The development of direct peroral cholangioscopy (DPOC) using an ultraslim endoscope simplifies biliary cannulation. The conventional techniques are cumbersome to perform and require advanced skills. The recent introduction of the guidewires and balloons has improved the therapeutic outcomes. Here we describe an effective and easier method for performing DPOC using an ultraslim upper endoscope. Indications for DPOC were the presence of stones on follow-up of patients who had previously undergone complete sphincteroplasty, including endoscopic sphincterotomy or endoscopic papillary large balloon dilatation. Fifteen patients underwent DPOC. An ultraslim endoscope was inserted perorally and was advanced into the major papilla. The ampulla of Vater was visualized by retroflexing the endoscope in the distal second portion of the duodenum, and then DPOC was performed using a wire-guided cannulation technique with an anchored intraductal balloon catheter. One patient failed in the treatment due to looping of the endoscope in the fornix of the stomach. Fourteen (93.3%) were successfully treated with our modified DPOC technique. Only one patient (6.7%) experienced an adverse event (pancreatitis) who responded well to conservative management. Residual stones of the common bile duct were completely removed in 3 patients. The modified method of DPOC is simple, safe and easy to access the bile duct.

AIM: To report our experience using a recently introduced anchoring balloon for diagnostic and therapeutic direct peroral cholangioscopy (DPOC). METHODS: Consecutive patients referred for diagnostic or therapeutic peroral cholangioscopy were evaluated in a prospective cohort study. The patients underwent DPOC using an intraductal anchoring balloon, which was recently introduced to allow consistent access to the biliary tree with an ultraslim upper endoscope. The device was later voluntarily withdrawn from the market by the manufacturer. RESULTS: Fourteen patients underwent DPOC using the anchoring balloon. Biliary access with an ultraslim upper endoscope was accomplished in all 14 patients. In 12 (86%) patients, ductal access required sphincteroplasty with a 10-mm dilating balloon. Intraductal placement of the ultraslim upper endoscope allowed satisfactory visualization of the biliary mucosa to the level of the confluence of the right and left hepatic ducts in 13 of 14 patients (93%). Therapeutic interventions by DPOC were successfully completed in all five attempted cases (intraductal biopsy in one and DPOC guided laser lithotripsy in four). Adverse events occurred in a patient on immunosuppressive therapy who developed an intrahepatic biloma at the site of the anchoring balloon. This required hospitalization and antibiotics. Repeat endoscopic retrograde cholangiopancreatography 8 wk after the index procedure showed resolution of the biloma. CONCLUSION: Use of this anchoring balloon allowed consistent access to the biliary tree for performance of diagnostic and therapeutic DPOC distal to the biliary bifurcation. PMID:22912549

The incidence of residual stones after mechanical lithotripsy for retained common bile duct (CBD) stones is relatively high. Peroral cholangioscopy using a mother-baby system may be useful for confirming complete extraction of stones, but has several limitations regarding routine use. We evaluated the role of direct peroral cholangioscopy (DPOC) using an ultraslim upper endoscope for the evaluation and removal of residual CBD stones after mechanical lithotripsy. From August 2006 to November 2010, 48 patients who had undergone mechanical lithotripsy for retained CBD stones with no evidence of filling defects in balloon cholangiography were recruited. The bile duct was inspected by DPOC after balloon cholangiography. Detected residual CBD stones were directly retrieved with a basket or balloon catheter under DPOC. The incidence of residual stones detected by DPOC, and the success rate of residual stone retrieval under DPOC were investigated. DPOC was successfully performed in 46 of the 48 patients (95.8%). Of these, 13 patients (28.3%) had residual CBD stones (mean number 1.4, range 1-3; mean diameter 4.5 mm, range 2.3-9.6). The residual stones were removed directly under DPOC in 11 of these patients (84.6%). There were no complications associated with DPOC or stone removal. DPOC using an ultraslim upper endoscope is a useful endoscopic procedure for the evaluation and extraction of residual stones after mechanical lithotripsy for retained CBD stones. © Georg Thieme Verlag KG Stuttgart · New York.

An 89-year-old man was referred to our hospital for treatment of hepatolithiasis causing recurrent cholangitis. He had undergone a prior Whipple procedure. Computed tomography demonstrated left-sided hepatolithiasis. First, we conducted peroral direct cholangioscopy (PDCS) using an ultraslim endoscope. Although PDCS was successfully conducted, it was unsuccessful in removing all the stones. The stones located in the B2 segment were difficult to remove because the endoscope could not be inserted deeply into this segment due to the small size of the intrahepatic bile duct. Next, we substituted the endoscope with an upper gastrointestinal endoscope. After positioning the endoscope, the SpyGlass digital system (SPY-DS) was successfully inserted deep into the B2 segment. Upon visualizing the residual stones, we conducted SPY-DS-guided electrohydraulic lithotripsy. The stones were disintegrated and completely removed. In cases of PDCS failure, a treatment strategy using the SPY-DS can be considered for patients with hepatolithiasis after a Whipple procedure.

An estimated 1.6 million breast biopsies are performed in the US each year. In order to provide real-time, in-vivo imaging with sub-cellular resolution for optical biopsies, we have designed an ultra-slim objective to fit inside the 1-mm-diameter hypodermic needles currently used for breast biopsies to image tissue stained by the fluorescent probe proflavine. To ensure high-quality imaging performance, experimental tests were performed to characterize fiber bundle’s light-coupling efficiency and simulations were performed to evaluate the impact of candidate lens materials’ autofluorescence. A prototype of NA = 0.4, 250-µm field of view, ultra-slim objective optics was built and tested, yielding diffraction-limited performance and estimated resolution of 0.9 µm. When used in conjunction with a commercial coherent fiber bundle to relay the image formed by the objective, the measured resolution was 2.5 µm. PMID:20389489

As displays and electronics evolve to become lighter, thinner, and more flexible, the choice of substrate continues to be critical to their overall optimization. The substrate directly affects improvements in the designs, materials, fabrication processes, and performance of advanced electronics. With their inherent benefits such as surface quality, optical transmission, hermeticity, and thermal and dimensional stability, glass substrates enable high-quality and long-life devices. As substrate thicknesses are reduced below 200 μm, ultra-slim flexible glass continues to provide these inherent benefits to high-performance flexible electronics such as displays, touch sensors, photovoltaics, and lighting. In addition, the reduction in glass thickness also allows for new device designs and high-throughput, continuous manufacturing enabled by R2R processes. This paper provides an overview of ultra-slim flexible glass substrates and how they enable flexible electronic device optimization. Specific focus is put on flexible glass' mechanical reliability. For this, a combination of substrate design and process optimizations has been demonstrated that enables R2R device fabrication on flexible glass. Demonstrations of R2R flexible glass processes such as vacuum deposition, photolithography, laser patterning, screen printing, slot die coating, and lamination have been made. Compatibility with these key process steps has resulted in the first demonstration of a fully functional flexible glass device fabricated completely using R2R processes.

Rebleeding and mortality rates remain high in patients with nonvariceal upper gastrointestinal bleeding. To identify clinical and endoscopic risk factors for rebleeding and mortality in patients with nonvariceal upper gastrointestinal bleeding. This study was performed in patients with nonvariceal upper gastrointestinal bleeding who underwent upper endoscopic procedures between July 2006 and February 2013. Clinical and endoscopic characteristics were compared among patients with and without rebleeding and mortality. Logistic regression analysis was performed to determine independent risk factors for rebleeding and mortality. After excluding 64 patients, data for 689 patients with nonvariceal upper gastrointestinal bleeding were analyzed. Peptic ulcer (62.6 %) was by far the most common source of bleeding. Endoscopic intervention was performed within 24 h in 99.0 % of patients, and successful endoscopic hemostasis was possible in 80.7 % of patients. The 30-day rebleeding rate was 13.1 % (n = 93). Unsuccessful endoscopic hemostasis was found to be the only independent risk factor for rebleeding (odds ratio 79.6; 95 % confidence interval 37.8-167.6; p = 0.000). The overall 30-day mortality rate was 3.2 % (n = 23). Unsuccessful endoscopic hemostasis (odds ratio 4.9; 95 % confidence interval 1.7-13.9; p = 0.003) was also associated with increased 30-day mortality in patients with nonvariceal upper gastrointestinal bleeding. Successful endoscopic hemostasis is an independent protective factor for both rebleeding and mortality in patients with nonvariceal upper gastrointestinal bleeding.

Selecting patients with an urgent need for endoscopic hemostasis is difficult based only on simple parameters of presumed acute upper gastrointestinal bleeding. This study assessed easily applicable factors to predict cases in need of urgent endoscopic hemostasis due to acute upper gastrointestinal bleeding. The consecutively included patients were divided into the endoscopic hemostasis and nonendoscopic hemostasis groups. We reviewed the enrolled patients' medical records and analyzed various variables and parameters for acute upper gastrointestinal bleeding outcomes such as demographic factors, comorbidities, symptoms, signs, laboratory findings, rebleeding rate, and mortality to evaluate simple predictive factors for endoscopic treatment. A total of 613 patients were analyzed, including 329 patients in the endoscopic hemostasis and 284 patients in the non-endoscopic hemostasis groups. In the multivariate analysis, a bloody nasogastric lavage (adjusted odds ratio [AOR], 6.786; 95% confidence interval [CI], 3.990 to 11.543; p < 0.0001) and a hemoglobin level less than 8.6 g/dL (AOR, 1.768; 95% CI, 1.028 to 3.039; p = 0.039) were independent predictors for endoscopic hemostasis. Significant differences in the morbidity rates of endoscopic hemostasis were detected between the group with no predictive factors and the group with one or more predictive factors (OR, 2.677; 95% CI, 1.920 to 3.733; p < 0.0001). A bloody nasogastric lavage and hemoglobin < 8.6 g/dL were independent predictors of endoscopic hemostasis in patients with acute upper gastrointestinal bleeding.

Endoscopic management of upper tract urothelial carcinoma has become more popular over the last few decades as there has been an impetus for renal preservation in these patients. While radical nephroureterectomy has been the gold standard in treatment of this disease, ureteroscopic and percutaneous management has become a viable option for select patients. The literature on endoscopic management of upper urinary tract tumors was explored. Different management methods are discussed, both from published literature and experience of the authors of this chapter. We review the indications, details of the procedure, and troubleshooting methods in the endoscopic management of upper tract urothelial carcinoma. Imperative indications as well as controversial indications are discussed. The role and efficacy of adjuvant intrarenal topical agents are examined as well as the protocol for administering these agents. Follow-up protocols are also reviewed. In select patients, endoscopic management with ureteroscopy and/or percutaneous resection of upper tract urothelial tumors is appropriate and can preserve renal function while obtaining comparable oncologic control compared with radical surgery.

To determine the effectiveness of endoscopic cricopharyngeal myotomy on upper oesophageal sphincter dysfunction in adults with upper oesophageal sphincter dysfunction and neurological disease. Published and unpublished studies with a quasi-experimental design investigating endoscopic cricopharyngeal myotomy effects on upper oesophageal sphincter dysfunction in humans were considered eligible. Electronic databases, grey literature and reference lists of included studies were systematically searched. Data were extracted by two independent reviewers. Methodological quality was assessed independently using the PEDro scale and MINORS tool. Of 2938 records identified, 2 studies were eligible. Risk of bias assessment indicated areas of methodological concern in the literature. Statistical analysis was not possible because of the limited number of eligible studies. No determinations could be made regarding endoscopic cricopharyngeal myotomy effectiveness in the cohort of interest. Reliable and valid evidence on the following is required to support increasing clinical usage of endoscopic cricopharyngeal myotomy: optimal candidacy selection; standardised post-operative management protocol; complications; and endoscopic cricopharyngeal myotomy effects on aspiration of food and laryngeal penetration, mean upper oesophageal sphincter resting pressure and quality of life.

Peroral cholangioscopic lithotripsy is a useful procedure in patients with a normal gastrointestinal anatomy who have difficult-to-treat stones. We evaluated the usefulness of peroral direct cholangioscopy (PDCS) using single-balloon enteroscope (SBE) in patients with difficult-to-treat stones who had undergone Roux-en-Y reconstruction. Among 118 patients (169 sessions) who underwent SBE-assisted endoscopic retrograde cholangiopancreatography to treat biliary stones after Roux-en-Y reconstruction, patients in whom it was difficult to remove biliary stones via a transpapillary or transanastomotic approach and difficult to switch to ultra-slim endoscope, were retrospectively enrolled. The biliary insertion success rate, procedure success rate, procedure time, and procedural complications were assessed. The SBE was inserted into the bile-duct, first using a free-hand technique, second using a guide wire, and third using the large balloon anchoring and deflation (LBAD) technique. A total of 11 patients (14 sessions) were enrolled in this study. The biliary insertion success rate was 100%. Bile-duct insertion was performed using a free-hand technique in 4 sessions, a guide wire in 3 sessions (rendezvous technique, 2 sessions), and the LBAD technique in 7 sessions. The procedure success rate was 86% in first session, and 100% in second session. The median procedure time was 81 min (range 49-137). The median procedure time in the bile-duct was 21.5 min (range 6-60). Mild pancreatitis occurred as a complication in one patient. The median follow-up was 528 days (range 282-764). No patient had stone recurrence. PDCS using SBE is a useful procedure in patients with Roux-en-Y reconstruction. The LBAD technique is an useful technique of inserting SBE into the bile-duct.

Nonvariceal upper gastrointestinal (UGI) bleeding recurs after appropriate endoscopic therapy in 10 % - 15 % of cases. The mortality rate can be as high as 25 % when bleeding recurs, but there is no consensus about the best modality for endoscopic re-treatment. The aim of this study was to evaluate clipping and detachable snaring (CDS) for rescue endoscopic control of nonvariceal UGI hemorrhage. We report a case series of seven patients from a Korean tertiary center who underwent endoscopic hemostasis using the combined method of detachable snares with hemoclips. The success rate of endoscopic hemostasis with CDS was 86 %: six of the seven patients who had experienced primary endoscopic treatment failure or recurrent bleeding after endoscopic hemostasis were treated successfully. In conclusion, rescue endoscopic bleeding control by means of CDS is an option for controlling nonvariceal UGI bleeding when no other method of endoscopic treatment for recurrent bleeding and primary hemostatic failure is possible. © Georg Thieme Verlag KG Stuttgart · New York.

Pre-endoscopic triage of patients who require an early upper endoscopy can improve management of patients with non-variceal upper gastrointestinal bleeding. To validate a new simplified clinical score (T-score) to assess the need of an early upper endoscopy in non variceal bleeding patients. Secondary outcomes were re-bleeding rate, 30-day bleeding-related mortality. In this prospective, multicentre study patients with bleeding who underwent upper endoscopy were enrolled. The accuracy for high risk endoscopic stigmata of the T-score was compared with that of the Glasgow Blatchford risk score. Overall, 602 patients underwent early upper endoscopy, and 472 presented with non-variceal bleeding. High risk endoscopic stigmata were detected in 145 (30.7%) cases. T-score sensitivity and specificity for high risk endoscopic stigmata and bleeding-related mortality was 96% and 30%, and 80% and 71%, respectively. No statistically difference in predicting high risk endoscopic stigmata between T-score and Glasgow Blatchford risk score was observed (ROC curve: 0.72 vs. 0.69, p=0.11). The two scores were also similar in predicting re-bleeding (ROC curve: 0.64 vs. 0.63, p=0.4) and 30-day bleeding-related mortality (ROC curve: 0.78 vs. 0.76, p=0.3). The T-score appeared to predict high risk endoscopic stigmata, re-bleeding and mortality with similar accuracy to Glasgow Blatchford risk score. Such a score may be helpful for the prediction of high-risk patients who need a very early therapeutic endoscopy. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l.

Studies describing the prevalence of upper gastrointestinal (GI) Crohn disease (CD) and its histopathologic changes have been inconsistent as a result of different definitions used for upper GI involvement, diverse populations, and varying indications for endoscopy. We reviewed the literature describing endoscopic findings and histologic lesions in gastric and duodenal mucosa of patients with established CD. PubMed, EMBASE, and the Cochrane Library were searched for gastroduodenal biopsy findings in patients with CD from 1970 to 2014. We included all retrospective and prospective studies in adults. We calculated the prevalence of the most common endoscopic and histopathological findings among patients with overall CD and upper GI CD. Of the 385 articles identified, 20 eligible studies were included. A total of 2511 patients had CD and 815 had upper GI CD. In the CD group, the most common histopathological finding was nonspecific gastric inflammation in 32% of patients, followed by gastric granuloma in 7.9%. Focal gastritis was prevalent in 30.9% of patients. In the upper GI CD group, gastric inflammation was present in 84% of patients, followed by duodenal inflammation in 28.2% and gastric granuloma in 23.2%. The most common gastric endoscopic finding in patients with CD was erythema in 5.9%, followed by erosions in 3.7%. Duodenal endoscopic findings included ulcers and erythema in 5.3% and 3.0% of patients, respectively. We found a prevalence of 34% for CD involving the upper GI tract across these 20 studies. Routine upper endoscopy with biopsies of the upper GI tract in the diagnostic workup of patients with CD can correctly classify the distribution and extent of the disease.

AIM: To investigate predictive risk factors associated with complications in the endoscopic removal of foreign bodies from the upper gastrointestinal tract. METHODS: We retrospectively reviewed the medical records of 194 patients with a diagnosis of foreign body impaction in the upper gastrointestinal tract, confirmed by endoscopy, at two university hospital in South Korea. Patient demographic data, including age, gender, intention to ingestion, symptoms at admission, and comorbidities, were collected. Clinical features of the foreign bodies, such as type, size, sharpness of edges, number, and location, were analyzed. Endoscopic data those were analyzed included duration of foreign body impaction, duration of endoscopic performance, endoscopic device, days of hospitalization, complication rate, 30-d mortality rate, and the number of operations related to foreign body removal. RESULTS: The types of upper gastrointestinal foreign bodies included fish bones, drugs, shells, meat, metal, and animal bones. The locations of impacted foreign bodies were the upper esophagus (57.2%), mid esophagus (28.4%), stomach (10.8%), and lower esophagus (3.6%). The median size of the foreign bodies was 26.2 ± 16.7 mm. Among 194 patients, endoscopic removal was achieved in 189, and complications developed in 51 patients (26.9%). Significant complications associated with foreign body impaction and removal included deep lacerations with minor bleeding (n = 31, 16%), ulcer (n = 11, 5.7%), perforation (n = 3, 1.5%), and abscess (n = 1, 0.5%). Four patients underwent operations because of incomplete endoscopic foreign body extraction. In multivariate analyses, risk factors for endoscopic complications and failure were sharpness (HR = 2.48, 95%CI: 1.07-5.72; P = 0.034) and a greater than 12-h duration of impaction (HR = 2.42, 95%CI: 1.12-5.25, P = 0.025). CONCLUSION: In cases of longer than 12 h since foreign body ingestion or sharp-pointed objects, rapid endoscopic intervention should be provided in patients with ingested foreign bodies.

Foreign bodies in the upper esophagus should be removed as soon as possible to avoid serious complications. However, removals of foreign bodies in the upper esophagus are very difficult, especially if they have sharp edges, such as press-through-packs (PTPs). We experienced four cases of the impacted PTPs in the upper esophagus which was successfully extracted endoscopically with the overtube. Because two edges of PTPs were so firmly impacted in the esophageal wall in all cases, the PTPs were not movable in the upper esophagus. However, after insertion of the overtube, PTPs became movable and were successfully extracted and no serious complications occurred after extraction of PTPs. In one case, insertion of the overtube rapidly expanded the upper esophagus and PTP progressed to the gastric cavity and it could be extracted with the endoscopic protector hood. The endoscopic removal with the overtube was a simple, safe and effective technique for the removal of the impacted PTPs in upper esophagus.

This report describes a new, minimally invasive procedure, posterior percutaneous endoscopic cervical diskectomy, performed with a unilateral biportal endoscopic approach. The procedure is used to treat cervical foraminal soft disk protrusion. This report also describes the short-term results with this procedure. In 2015, 14 patients underwent this new, minimally invasive procedure. The technique was applied with a standard arthroscopy device and conventional spine instruments. The Neck Disability Index and visual analog scale scores for the neck and upper arm were evaluated, and 13 consecutive patients were included in the analysis. Mean follow-up was 14.8 months (range, 12-18 months). The Neck Disability Index decreased from 27.0±2.5 to 6.8±1.4 at the last follow-up (P<.05). Visual analog scale scores for the neck and upper arm also decreased significantly (neck, 6.2±0.8 to 2.4±0.9; upper arm, 7.0±1.1 to 2.2±0.6). Posterior percutaneous endoscopic cervical diskectomy with a uniportal endoscope provides a clear operative field because of continuous endoscopic saline irrigation and requires only a short hospitalization and no postoperative rehabilitation. Posterior percutaneous endoscopic cervical diskectomy with a unilateral biportal endoscopic approach also can be performed efficiently because of the wide field of visualization and familiar surgical field. Thus, posterior percutaneous endoscopic cervical diskectomy with the unilateral biportal endoscopic approach may be an alternative procedure for cervical foraminal soft disk protrusion.

The incidence of clinically relevant anastomotic leaks after upper gastrointestinal surgery is approximately 4% to 20%, and the associated mortality is up to 80%. Depending on the clinical presentation, the treatment options include surgery, conservative treatment with or without external drainage or endoscopic treatment. This report presents nine cases of anastomotic leaks or fistulae after surgery for upper gastrointestinal cancers that were treated by insertion of a Vicryl plug and sealing with fibrin glue. Under sedation, all nine patients underwent endoscopic lavage of the cavity at the site of anastomotic leakage. The entrance to the cavity then was filled with Vicryl mesh and sealed off with fibrin glue. After the procedure, the patients underwent endoscopy and a water-soluble contrast study for assessment of the result. Seven of the nine patients had complete healing of the anastomotic leak or fistula after one to two endoscopic treatments. In one case, the treatment failed immediately because of a large and direct tracheoesophageal fistula. Another patient experienced recurrent intrathoracic abscesses after initial technical success. Postoperative upper gastrointestinal fistulas or anastomotic leaks can be managed successfully with little morbidity by means of endoscopic insertion of Vicryl mesh with fibrin glue, thereby avoiding repetitive major surgery and its associated risks.
Prevalence of incidental pancreatic cyst on upper endoscopic ultrasound
Martínez, Belén; Martínez, Juan F.; Aparicio, José R.
2018-01-01
Background: This study aimed to determine the prevalence of incidental pancreatic cysts in patients undergoing upper endoscopic ultrasound without a known pancreatic abnormality. Methods: This prospective study was conducted in two hospitals in Spain and enrolled consecutive patients referred for upper endoscopic ultrasound for a condition unrelated to the pancreas. Patients with a previous pancreatic anomaly, history of acute or chronic pancreatitis, evidence of acute pancreatitis, previous upper gastrointestinal surgery, or chronic abdominal pain suggestive of pancreatic origin were excluded. Univariate logistic regression was performed to evaluate individual covariates and the incidental pancreatic cyst risk. Results: A total of 298 patients were included, of whom 64 had pancreatic cysts (21.5%; 16.9-26.6%). The mean size of the cysts was 6.3±3.7 (range 3-25) mm. Six cysts (2%) were >10 mm and 16 (5.4%) were compatible with branch duct intraductal papillary mucinous neoplasm. The pancreatic cyst prevalence was similar in the two hospitals and increased significantly with age. Conclusion: The prevalence of incidental pancreatic cysts during endoscopic ultrasound was very high in our study population. PMID:29333072

For 4 decades, stigmata of recent hemorrhage in patients with nonvariceal lesions have been used for risk stratification and endoscopic hemostasis. The arterial blood flow that underlies the stigmata rarely is monitored, but can be used to determine risk for rebleeding. We performed a randomized controlled trial to determine whether Doppler endoscopic probe monitoring of blood flow improves risk stratification and outcomes in patients with severe nonvariceal upper gastrointestinal hemorrhage. In a single-blind study performed at 2 referral centers we assigned 148 patients with severe nonvariceal upper gastrointestinal bleeding (125 with ulcers, 19 with Dieulafoy's lesions, and 4 with Mallory Weiss tears) to groups that underwent standard, visually guided endoscopic hemostasis (control, n = 76), or endoscopic hemostasis assisted by Doppler monitoring of blood flow under the stigmata (n = 72). The primary outcome was the rate of rebleeding after 30 days; secondary outcomes were complications, death, and need for transfusions, surgery, or angiography. There was a significant difference in the rates of lesion rebleeding within 30 days of endoscopic hemostasis in the control group (26.3%) vs the Doppler group (11.1%) (P = .0214). The odds ratio for rebleeding with Doppler monitoring was 0.35 (95% confidence interval, 0.143-0.8565) and the number needed to treat was 7. In a randomized controlled trial of patients with severe upper gastrointestinal hemorrhage from ulcers or other lesions, Doppler probe guided endoscopic hemostasis significantly reduced 30-day rates of rebleeding compared with standard, visually guided hemostasis. Guidelines for nonvariceal gastrointestinal bleeding should incorporate these results. ClinicalTrials.gov no: NCT00732212 (CLIN-013-07F). Copyright © 2017 AGA Institute. Published by Elsevier Inc.

We introduce Endoscopic Low Coherence Interferometry to obtain topology of upper airways through commonly used rigid endoscopes. Quantitative dimensioning of upper airways pathologies is crucial to provide maximum health recovery chances, for example in order to choose the correct stent to treat endoluminal obstructing pathologies. Our device is fully compatible with procedures used in day-to-day examinations and can potentially be brought to bedside. Besides this, the approach described here can be almost straightforwardly adapted to other endoscopy-related field of interest, such as gastroscopy and arthroscopy. The principle of the method is first exposed, then filtering procedure used to extract the depth information is described. Finally, demonstration of the method ability to operate on biological samples is assessed through measurements on ex-vivo pork bronchi.

Acute upper gastrointestinal (GI) bleeding is a common medical emergency. A common risk factor of upper GI bleeding is cirrhosis of liver, which can lead to variceal haemorrhage. 30-40% of cirrhotic patients who bleed may have non-variceal upper GI bleeding and it is frequently caused by peptic ulcers, portal gastropathy, Mallory-Weiss tear, and gastroduodenal erosions. The objective of this study was to determine the frequency of upper gastrointestinal endoscopic findings among patients presenting with upper gastrointestinal bleeding with liver cirrhosis. This descriptive cross-sectional study was carried out in Gastroenterology & Hepatology Department of Ayub Teaching Hospital, Abbottabad from February 2012 to June 2013. 252 patients diagnosed with cirrhosis, presenting with upper GI bleed, age 50 years of either gender, and were included in the study. Non-probability consecutive sampling was used, Endoscopy was performed on each patient and the findings documented. The mean age was 57.84 +/- 6.29 years. There were 158 (62.7%) males and 94 (37.3%) females. The most common endoscopic finding was oesophageal varices (92.9%, n=234) followed by portal hypertensive gastropathy (38.9%, n=98) with almost equal distribution among males and females. Gastric varices were found in 33.3% of patients (n=84). Among other non-variceal lesions, peptic ulcer disease was seen in 26 patients (10.3%) while gastric erosions were found in 8 patients (3.2%). In patients with acute upper GI bleeding and liver cirrhosis, the most common endoscopic finding is oesophageal varices, with a substantially higher value in our part of the country, apart from other non-variceal causes.

Upper non-variceal gastrointestinal bleeding is a condition that requires immediate medical intervention and has a high associated mortality rate (exceeding 10%). The vast majority of upper gastrointestinal bleeding cases are due to peptic ulcers. Helicobacter pylori infection, non-steroidal anti-inflammatory drugs and aspirin are the main risk factors for peptic ulcer disease. Endoscopic therapy has generally been recommended as the first-line treatment for upper gastrointestinal bleeding as it has been shown to reduce recurrent bleeding, the need for surgery and mortality. Early endoscopy (within 24 h of hospital admission) has a greater impact than delayed endoscopy on the length of hospital stay and requirement for blood transfusion. This paper aims to review and compare the efficacy of the types of endoscopic hemostasis most commonly used to control non-variceal gastrointestinal bleeding by pooling data from the literature.

Although well documented in racehorses, there is paucity in the literature regarding the prevalence of dynamic upper airway abnormalities in nonracing performance horses. To describe upper airway function of nonracing performance horses with abnormal respiratory noise and/or poor performance via exercising upper airway videoendoscopy. Medical records of nonracing performance horses admitted for exercising evaluation with a chief complaint of abnormal respiratory noise and/or poor performance were reviewed. All horses had video recordings of resting and exercising upper airway endoscopy. Relationships between horse demographics, resting endoscopic findings, treadmill intensity and implementation of head and neck flexion during exercise with exercising endoscopic findings were examined. Dynamic upper airway obstructions were observed in 72% of examinations. Head and neck flexion was necessary to obtain a diagnosis in 21 horses. Pharyngeal wall collapse was the most prevalent upper airway abnormality, observed in 31% of the examinations. Complex abnormalities were noted in 27% of the examinations. Resting laryngeal dysfunction was significantly associated with dynamic arytenoid collapse and the odds of detecting intermittent dorsal displacement of the soft palate (DDSP) during exercise in horses with resting DDSP was only 7.7%. Exercising endoscopic observations were different from the resting observations in 54% of examinations. Dynamic upper airway obstructions were common in nonracing performance horses with respiratory noise and/or poor performance. Resting endoscopy was only helpful in determining exercising abnormalities with recurrent laryngeal neuropathy. This study emphasises the importance of exercising endoscopic evaluation in nonracing performance horses with abnormal respiratory noise and/or poor performance for accurate assessment of dynamic upper airway function. © 2010 EVJ Ltd.

Upper gastrointestinal (GI) bleeding is a common medical emergency associated with significant morbidity and mortality. The clinical presentation depends on the amount and location of hemorrhage and the endoscopic profile varies according to different etiology. At present, there are limited epidemiological data on upper GI bleed and associated mortality from India, especially in the middle and elderly age group, which has a higher incidence and mortality from this disease. This study aims to study the clinical and endoscopic profile of middle aged and elderly patients suffering from upper GI bleed to know the etiology of the disease and outcome of the intervention. Out of a total of 1790 patients who presented to the hospital from May 2015 to August 2017 with upper GI bleed, and underwent upper GI endoscopy, data of 1270 patients, aged 40 years and above, was compiled and analyzed retrospectively. All the patients included in the study were above 40 years of age. Majority of the patients were males, with a male to female ratio of 1.6:1. The most common causes of upper GI bleed in these patients were portal hypertension-related (esophageal, gastric and duodenal varices, portal hypertensive gastropathy, and gastric antral vascular ectasia GAVE), seen in 53.62% of patients, followed by peptic ulcer disease (gastric and duodenal ulcers) seen in 17.56% of patients. Gastric erosions/gastritis accounted for 15.20%, and duodenal erosions were seen in 5.8% of upper GI bleeds. The in-hospital mortality rate in our study population was 5.83%. The present study reported portal hypertension as the most common cause of upper GI bleeding, while the most common endoscopic lesions reported were esophageal varices, followed by gastric erosion/gastritis, and duodenal ulcer.

Background/Aims: To validate the AIMS65 score for predicting mortality of patients with nonvariceal upper gastrointestinal bleeding and to evaluate the effectiveness of urgent (<8 hours) endoscopic procedures in patients with high AIMS65 scores. Methods: This was a 5-year single-center, retrospective study. Nonvariceal, upper gastrointestinal bleeding was assessed by using the AIM65 and Rockall scores. Scores for mortality were assessed by calculating the area under the receiver-operating characteristic curve (AUROC). Patients with high AIMS65 scores (≥2) were allocated to either the urgent or non-urgent endoscopic procedure group. In-hospital mortality, success of endoscopic procedure, recurrence of bleeding, admission period, and dose of transfusion were compared between groups. Results: A total of 634 patients were analyzed. The AIMS65 score successfully predicted mortality (AUROC=0.943; 95% confidence interval [CI], 0.876 to 0.99) and was superior to the Rockall score (AUROC=0.856; 95% CI, 0.743 to 0.969) in predicting mortality. The group with high AIMS65 score included 200 patients. The urgent endoscopic procedure group had reduced hospitalization periods (p<0.05) Conclusions: AIMS65 score may be useful in predicting mortality in patients with nonvariceal upper gastrointestinal bleeding. Urgent endoscopic procedures in patients with high scores may be related to reduced hospitalization periods. PMID:26668799

Non-variceal upper gastrointestinal bleeding remains an important emergency condition, leading to significant morbidity and mortality. As endoscopic therapy is the 'gold standard' of management, treatment of these patients can be considered in three stages: pre-endoscopic treatment, endoscopic haemostasis and post-endoscopic management. Since publication of the Asia-Pacific consensus on non-variceal upper gastrointestinal bleeding (NVUGIB) 7 years ago, there have been significant advancements in the clinical management of patients in all three stages. These include pre-endoscopy risk stratification scores, blood and platelet transfusion, use of proton pump inhibitors; during endoscopy new haemostasis techniques (haemostatic powder spray and over-the-scope clips); and post-endoscopy management by second-look endoscopy and medication strategies. Emerging techniques, including capsule endoscopy and Doppler endoscopic probe in assessing adequacy of endoscopic therapy, and the pre-emptive use of angiographic embolisation, are attracting new attention. An emerging problem is the increasing use of dual antiplatelet agents and direct oral anticoagulants in patients with cardiac and cerebrovascular diseases. Guidelines on the discontinuation and then resumption of these agents in patients presenting with NVUGIB are very much needed. The Asia-Pacific Working Group examined recent evidence and recommends practical management guidelines in this updated consensus statement. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

In this study, the authors introduce and evaluate the feasibility of endoscopic resection using the retroauricular approach for various benign lesions of the upper neck. A retrospective comparative analysis was performed on the clinical outcomes of patients who underwent surgery for upper neck masses as endoscopic resection using the retroauricular approach or conventional transcervical resection at the authors' center from January 2010 through August 2011. The primary outcome was the cosmetic satisfaction of the patients in each group. In addition, the feasibility of the procedure was evaluated by comparing the operation time; hospital stay; amount and duration of drainage; complications such as marginal mandibular nerve, lingual, or hypoglossal nerve palsy; paresthesia of the ear lobe; and wound problems such as hematoma and skin necrosis. Statistical analysis was performed by independent-samples t test and the Fisher exact test, and a P value less than .05 was considered statistically significant. Thirty-six patients underwent endoscopic resection (endo group; 15 men, 21 women; mean age, 38.8 ± 15.0 years) and 40 patients underwent conventional transcervical resection (conventional group; 18 men, 22 women; mean age, 45.1 ± 14.1 years). The operating time in the endo group was longer than in the conventional group (P = .003). No significant difference was observed in the overall perioperative complications between the 2 groups. Cosmetic satisfaction evaluated with a graded scale showed much better results in the endo group (P < .001). Endoscopic resection using the retroauricular approach is feasible for various benign upper neck masses when conducted by an experienced endoscopic surgeon, with excellent cosmetic results.

Foreign body ingestion is a relatively common occurrence, which may lead to morbidity and mortality. The aim of the present study was to report the experience of management of upper gastrointestinal foreign bodies by endoscopy in a large center. All patients who presented at the Department of Gastroenterology at Nanfang Hospital (Guangzhou, China) with complaints regarding upper gastrointestinal (GI) foreign body ingestion from December 1987 to December 2013. Hospital medical charts and endoscopic records were examined to evaluate etiology, treatment, and outcomes for these patients. A total of 846 patients were enrolled in the present study, from which foreign bodies were detected in 737 (87.1%) patients via X-ray or endoscopy. The objects most frequently ingested were bones (n=395, 53.6%). The detected foreign bodies were predominantly located in the cervical esophagus (n=325, 44.1%). Endoscopic foreign body extraction was successful in 92.5% of cases, whereas surgery was required in 6 patients. The most frequently used endoscopic accessory devices were retrieval forceps (n=480, 65.1%). The complication rate was 6.9%, including mucosal laceration (n=10) and others, all of which were managed conservatively. Associated GI diseases were reported in 74 (10.0%) patients, including postesophagectomy (n=34) and others. In conclusion, the endoscopic procedure was safe and effective for the removal of foreign bodies from the upper gastrointestinal tract, with a high success rate and low complication rate.

Transcatheter arterial embolization (TAE) is a therapeutic option for endoscopically unmanageable upper gastrointestinal (GI) bleeding. We aimed to assess the efficacy and clinical outcomes of TAE for acute non-variceal upper GI bleeding and to identify predictors of recurrent bleeding within 30 days. Visceral angiography was performed in 66 patients (42 men, 24 women; mean age, 60.3 ± 12.7 years) who experienced acute non-variceal upper GI bleeding that failed to be controlled by endoscopy during a 7-year period. Clinical information was reviewed retrospectively. Outcomes included technical success rates, complications, and 30-day rebleeding and mortality rates. TAE was feasible in 59 patients. The technical success rate was 98%. Rebleeding within 30 days was observed in 47% after an initial TAE and was managed with re-embolization in 8, by endoscopic intervention in 5, by surgery in 2, and by conservative care in 12 patients. The 30-day overall mortality rate was 42.4%. In the case of initial endoscopic hemostasis failure (n = 34), 31 patients underwent angiographic embolization, which was successful in 30 patients (96.8%). Rebleeding occurred in 15 patients (50%), mainly because of malignancy. Two factors were independent predictors of rebleeding within 30 days by multivariate analysis: coagulopathy (odds ratio [OR] = 4.37; 95% confidence interval [CI]: 1.25-15.29; p = 0.021) and embolization in ≥2 territories (OR = 4.93; 95% CI: 1.43-17.04; p = 0.012). Catheterization-related complications included hepatic artery dissection and splenic embolization. TAE controlled acute non-variceal upper GI bleeding effectively. TAE may be considered when endoscopic therapy is unavailable or unsuccessful. Correction of coagulopathy before TAE is recommended.

Hemospray is a new endoscopic haemostatic powder that can be used in the management of upper gastrointestinal bleedings. To assess the efficacy and safety of Hemospray as monotherapy for the treatment of acute upper gastrointestinal bleeding due to cancer. The endoscopy databases of 3 Italian Endoscopic Units were reviewed retrospectively and 15 patients (8 males; mean age 74 years) were included in this study. Immediate haemostasis was achieved in 93% of cases. Among the successful cases, 3 re-bled, one case treated with Hemospray and injection had a good outcome, while 2 cases died both re-treated with Hemospray, injection and thermal therapy. No complications related to Hemospray occurred. Finally, 80% of patients had a good clinical outcome at 30days and 50% at six months. Hemospray may be considered an effective and safe method for the endoscopic management of acute neoplastic upper gastrointestinal bleedings.

To validate the menstrual pictogram (superabsorbent polymer-c version) for Always Ultra-slim feminine towels containing superabsorbent polymers. Prospective, multicenter, evaluator-blinded study. Three gynecology research clinics in the United Kingdom. Women with self-perceived light, normal, or heavy menstrual periods who had not previously used a graphical method to assess their menstrual loss. One hundred twenty-two women were asked to complete the menstrual pictogram throughout two menstrual periods and collect their feminine towels for measurements of menstrual blood loss (MBL) by the alkaline hematin method and total menstrual fluid loss (MFL) by fluid weight. Agreement of menstrual pictogram MBL and MFL scores with alkaline hematin and towel weight, respectively. The percentage blood fraction was determined at various volumes of menstrual discharge. Alkaline hematin and fluid weight were highly correlated (r = .97). However, the percentage blood fraction progressively increased with total MFL and MBL score. After correction for this incremental rise in blood fraction, the menstrual pictogram gave a sensitivity of 82% and a specificity of 92% for a diagnosis of heavy menstrual bleeding. The menstrual pictogram (superabsorbent polymer-c version) provides a simple means of measuring MBL in the clinical setting. Copyright © 2014 American Society for Reproductive Medicine.

The efficacy of computed tomography (CT) in detailing upper urinary tract calculi is well established. There is no established acceptable annual recommended limit for medical exposure, yet the global accepted upper limit for occupational radiation exposure is <50 millisieverts (mSv) in any one year. We sought to appreciate the CT and fluoroscopic radiation exposure to our patients undergoing endoscopic removal of upper tract calculi during the periprocedure period. All patients undergoing upper urinary endoscopic stone removal between 2005 and 2009 were identified. To calculate the cumulative radiation exposure, we included all ionizing radiation imaging performed during a periprocedure period, which we defined as ≤90 days pre- and post-therapeutic procedure. A total of 233 upper urinary tract therapeutic patient stone procedures were identified; 127 patients underwent ureteroscopy (URS) and 106 patients underwent percutaneous nephrolithotomy (PCNL). A mean 1.58 CTs were performed per patient. Ninety (38.6%) patients underwent ≥2 CTs in the periprocedure period, with an average number in this group of 2.49 CT/patient, resulting in approximately 49.8 mSv of CT radiation exposure. Patients who were undergoing URS were significantly more likely to have multiple CTs (P=0.003) than those undergoing PCNL. Median fluoroscopic procedure exposures were 43.3 mGy for patients who were undergoing PCNL and 27.6 mGy for those patients undergoing URS. CT radiation exposure in the periprocedure period for patients who were undergoing endoscopic upper tract stone removal is considerable. Added to this is the procedure-related fluoroscopic radiation exposure. Urologic surgeons should be aware of the cumulative amount of ionizing radiation received by their patients from multiple sources.

Recent advances in endoscopic techniques have allowed minimally invasive approaches to the cranio-vertebral junction (CVJ) through the oropharynx (ETA) in addition to the transnasal approach (EEA). These minimally invasive endoscopic techniques allow for increased surgical exposure using no visible incisions, with a potential less morbidity. The ability to know preoperatively the limit of the ETA is vital for the surgical planning in order to better address CVJ pathology. The aim of the present study is to determine the anatomical limits of endoscopic dissection of the skull base and upper cervical spine through the transoral corridor and the superior limit reached by adopting this approach. Six fresh-frozen adult cadaver heads were dissected adopting ETA preserving the hard and soft palate. The most superior extent of the exposure was dissected. Post-operative CT scans were performed to confirm the superior extent. The superior most limit of dissection corresponded to the sphenoid-occipital junction, where the basilar portion of the occipital bone joins with the sphenoid bone's body. This ranged from 12.7 to 18.9 mm above the line of the hard palate. This was achieved without having to transgress any of the palatine structures. The sphenoid-occipital junction represents the rostral limit of endoscopic transoral approach to the lower skull base and CVJ area. This approach is limited superiorly by the orientation of the hard palate and mouth aperture and lower dentition due to the linear nature of the endoscope. Using the endoscope for this approach can allow for a more superior exposure than the traditional open transoral approach.

The diagnosis of intestinal lymphangiectasia (IL) has been associated with characteristic duodenal mucosal changes. However, the sensitivity and specificity of the endoscopic duodenal mucosal appearance for the diagnosis of IL are not reported. To evaluate the utility of endoscopic images of the duodenum for diagnosis of IL. Endoscopic appearance of the duodenal mucosal might predict histopathologic diagnosis of IL with a high degree of sensitivity and specificity. 51 dogs that underwent upper gastrointestinal (GI) endoscopy and endoscopic biopsies. Retrospective review of images acquired during endoscopy. Dogs were included if adequate biopsies were obtained during upper GI endoscopy and digital images were saved during the procedure. Images were assessed for the presence and severity of IL. Using histopathology as the gold standard, the sensitivity and specificity of endoscopy for diagnosing IL were calculated. Intestinal lymphangiectasia (IL) was diagnosed in 25/51 dogs. Gross endoscopic appearance of the duodenal mucosa had a sensitivity and specificity (95% confidence interval) of 68% (46%, 84%) and 42% (24%, 63%), respectively for diagnosis of IL. Endoscopic images in cases with lymphopenia, hypocholesterolemia, and hypoalbuminemia had a sensitivity of 80%. Endoscopic duodenal mucosa appearance alone lacks specificity and has only a moderate sensitivity for diagnosis of IL. Evaluation of biomarkers associated with PLE improved the sensitivity; however, poor specificity for diagnosis of IL supports the need for histopathologic confirmation.

Early refeeding after nonvariceal upper gastrointestinal bleeding is safe and reduces hospital stay/costs. The aim of this study was obtaining objective data on refeeding after nonvariceal upper gastrointestinal bleeding. From 1 year span records of nonvariceal upper gastrointestinal bleeding patients that underwent urgent endoscopy: clinical features; rockall score; endoscopic data, including severity of lesions and therapy; feeding related records of seven days: liquid diet prescription, first liquid intake, soft/solid diet prescription, first soft/solid intake. From 133 patients (84 men) Rockall classification was possible in 126: 76 score ≥5, 50 score <5. One persistent bleeding, eight rebled, two underwent surgery, 13 died. Ulcer was the major bleeding cause, 63 patients underwent endoscopic therapy. There was 142/532 possible refeeding records, no record 37% patients. Only 16% were fed during the first day and half were only fed on third day or later. Rockall <5 patients started oral diet sooner than Rockall ≥5. Patients that underwent endoscopic therapy were refed earlier than those without endotherapy. Most feeding records are missing. Data reveals delayed refeeding, especially in patients with low-risk lesions who should have been fed immediately. Nonvariceal upper gastrointestinal bleeding patients must be refed earlier, according to guidelines.
A case of gastric hamartomatous inverted polyp resected endoscopically
Dohi, Moyu; Gen, Yasuyuki; Yoshioka, Mika
2016-01-01
We report the case of a 55-year-old woman with a tumor in the greater curvature of the upper gastric body. The tumor was incidentally found on an upper gastrointestinal X-ray series performed during a routine medical examination. Whereas endoscopy revealed a gastric submucosal tumor (SMT), endoscopic ultrasonography demonstrated a heterogeneous tumor with small, cystic, hypoechoic spots originating from the second layer. The patient was clinically asymptomatic, with no contributory family history or abnormal laboratory data. The results of a physical examination, abdominal computed tomography, and plain chest radiography were all unremarkable. Although the endoscopic tumor type was determined to be SMT, the tumor was successfully resected by endoscopic submucosal dissection (ESD) and subsequently diagnosed as a gastric hamartomatous inverted polyp (GHIP). The findings of the present case highlight the importance of considering GHIP as a diagnosis and indicate the utility of en bloc resection of GHIP with ESD. PMID:27556064

Postoperative, iatrogenic or spontaneous upper gastrointestinal defects result in significant morbidity and mortality of the patients. In the last few years, endoscopic vacuum therapy (EVT) has been recognized as a new promising method for repairing upper gastrointestinal defects of different etiology. However, probably due to insufficient data and no commercially available system for EVT of the upper gastrointestinal tract, until the end of 2014, covering of esophageal defects with self-expanding metal stents (SEMS) were still the mainstay of endoscopic therapy. The aim of this article is to review the data available about EVT for various upper gastrointestinal defects. A selective literature search was conducted in Medline and PubMed (2007-2016), taking into account all the published case series and case reports reporting on the use of EVT in the management of upper gastrointestinal defects. EVT works through intracorporal application of negative pressure at the defect zone with an electronic controlled vacuum device along a polyurethane sponge drainage. This results in closure of the esophageal defect and internal drainage of the septic focus, simultaneously. Compared to stenting, EVT enables regular viewing of wound conditions with control of the septic focus and adjustment of therapy. Moreover, endoscopical negative pressure is applicable in all esophageal regions (cricopharygeal, tubular, gastroesophageal junction) and in anastomotic anatomic variants. EVT can be used solely as a definite treatment or as a complimentary therapy combined with operative revision. In total, there are published data of more than 200 patients with upper gastrointestinal defects treated with EVT, showing succes rates from 70-100%. The available data indicate that EVT is feasible, safe and effective with good short-term and long-term clinical outcomes in the damage control of upper GI-tract leaks. Still, a prospective multi-center study has to be conducted to proof the definite benefit of EVT for patients with esophageal defects.

Japan Gastroenterological Endoscopy Society (JGES) has compiled a set of guidelines for endoscopic management of non-variceal upper gastrointestinal bleeding using evidence-based methods. The major cause of non-variceal upper gastrointestinal bleeding is peptic gastroduodenal ulcer bleeding. As a result, these guidelines mainly focus on peptic gastroduodenal ulcer bleeding, although bleeding from other causes is also overviewed. From the epidemiological aspect, in recent years in Japan, bleeding from drug-related ulcers has become predominant in comparison with bleeding from Helicobacter pylori (HP)-related ulcers, owing to an increase in the aging population and coverage of HP eradication therapy by national health insurance. As for treatment, endoscopic hemostasis, in which there are a variety of methods, is considered to be the first-line treatment for bleeding from almost all causes. It is very important to precisely evaluate the severity of the patient's condition and stabilize the patient's vital signs with intensive care for successful endoscopic hemostasis. Additionally, use of antisecretory agents is recommended to prevent rebleeding after endoscopic hemostasis, especially for gastroduodenal ulcer bleeding. Eighteen statements with evidence and recommendation levels have been made by the JGES committee of these guidelines according to evidence obtained from clinical research studies. However, some of the statements that are supported by a low level of evidence must be confirmed by further clinical research. © 2016 Japan Gastroenterological Endoscopy Society.

Gas embolism is a rare but potentially devastating complication of endoscopic procedures. We describe 3 cases of gas embolism which were associated with endoscopic procedures (esophagogastroduodenoscopy and endoscopic retrograde cholangiopancreatography). We treated these at our hyperbaric medicine center with 3 different outcomes: complete resolution, death, and disability. We review the literature regarding this unusual complication of endoscopy and discuss the need for prompt identification and referral for hyperbaric oxygen therapy. Additional adjunctive therapies are also discussed.

Reports on endoscopic management of ingested foreign bodies of the upper-GI tract in China are scarce. To report our experience and outcome in the management of ingestion of foreign bodies in Chinese patients. Between January 1980 and January 2005, a total of 1088 patients (685 men and 403 women; age range, 1 day to 96 years old) with suspected foreign bodies were admitted to our endoscopy center. All patients underwent endoscopic procedure after admission. Demographic and endoscopic data, including age, sex, and referral sources of patients, types, number and location of foreign bodies, associated upper-GI diseases, endoscopic methods, and accessory devices for removal of foreign bodies were collected and analyzed. A total of 1090 foreign bodies were found in 988 (90.8%) patients. The types of foreign bodies varied greatly: mainly food boluses, coins, fish bones, dental prostheses, or chicken bones. The foreign bodies were located in the pharynx (n = 12), the esophagus (n = 577), the stomach (n = 441), the duodenum (n = 50), and the surgical anastomosis (n = 10). The associated GI diseases (n = 88) included esophageal carcinoma (33.0%), stricture (23.9%), diverticulum (15.9%), postgastrectomy (11.4%), hiatal hernia (10.2%), and achalasia (5.7%). A rat-tooth forceps and a snare were the most frequently used accessory devices. The success rate for foreign-body removal was 94.1% (930/988). Ingestion of foreign bodies is a common clinic problem in China. Endoscopy procedures are frequently performed, and a high proportion of patients with foreign bodies require endoscopic intervention.

Upper gastrointestinal endoscopies are primarily performed to observe the pathologies of the esophagus, stomach, and duodenum. However, when an endoscope is pushed into the esophagus or stomach by the physician, the organs behave similar to a balloon being gradually inflated. Consequently, their shapes and depth-of-field of images change continually, preventing thorough examination of the inflammation or anabrosis position, which delays the curing period. In this study, a 2.9-mm image-capturing module and a convoluted mechanism was incorporated into the tube like a standard 10- mm upper gastrointestinal endoscope. The scale-invariant feature transform (SIFT) algorithm was adopted to implement disease feature extraction on a koala doll. Following feature extraction, the smoothly varying affine stitching (SVAS) method was employed to resolve stitching distortion problems. Subsequently, the real-time splice software developed in this study was embedded in an upper gastrointestinal endoscope to obtain a panoramic view of stomach inflammation in the captured images. The results showed that the 2.9-mm image-capturing module can provide approximately 50 verified images in one spin cycle, a viewing angle of 120° can be attained, and less than 10% distortion can be achieved in each image. Therefore, these methods can solve the problems encountered when using a standard 10-mm upper gastrointestinal endoscope with a single camera, such as image distortion, and partial inflammation displays. The results also showed that the SIFT algorithm provides the highest correct matching rate, and the SVAS method can be employed to resolve the parallax problems caused by stitching together images of different flat surfaces.

Simethicone and N-acetylcysteine have been widely used in improving endoscopic visibility. However, the optimal dose, volume, and dosing time for the premedication regimen are still unclear. Our aim was to assess the efficacy of premedication in improving endoscopic visibility and determine the contributions of dose, volume, and premedication time. A total of 1849 patients were prospectively treated in three groups: group A: 100-mg simethicone suspension in 5 mL water; group B: 100-mg simethicone suspension in 100 mL water; and group C: 100-mg simethicone suspension in 100 mL water containing 200 mg N-acetylcysteine. Mucosa visibility was assessed at seven sites of upper gastrointestinal tract. The sum of scores was considered as total mucosal visibility score (TMVS). The upper body of stomach had the worst visibility score for all groups. TMVS of groups B and C were significantly lower than those of group A. Group C had a significantly fewer patients requiring endoscopic flushing than groups A and B. The TMVS for groups B and C were significantly lower than for group A within 30 min of beginning premedication. Beyond 30 min of premedication, there was no significant difference in the TMVS among groups. Premedication using 100 mg simethicone in 100 mL of water improves endoscopic visibility. Addition of N-acetylcysteine to simethicone in 100 mL of water reduces the need for endoscopic flushing. For patients unable to tolerate a large fluid volume, a 5-mL simethicone suspension administered more than 30 min prior to upper endoscopy is suggested. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

To overcome current limitations in combined transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI) studies by employing a dedicated coil array design for 3 Tesla. The state-of-the-art setup for concurrent TMS/fMRI is to use a large birdcage head coil, with the TMS between the subject's head and the MR coil. This setup has drawbacks in sensitivity, positioning, and available imaging techniques. In this study, an ultraslim 7-channel receive-only coil array for 3 T, which can be placed between the subject's head and the TMS, is presented. Interactions between the devices are investigated and the performance of the new setup is evaluated in comparison to the state-of-the-art setup. MR sensitivity obtained at the depth of the TMS stimulation is increased by a factor of five. Parallel imaging with an acceleration factor of two is feasible with low g-factors. Possible interactions between TMS and the novel hardware were investigated and were found negligible. The novel coil array is safe, strongly improves signal-to-noise ratio in concurrent TMS/fMRI experiments, enables parallel imaging, and allows for flexible positioning of the TMS on the head while ensuring efficient TMS stimulation due to its ultraslim design. © 2014 The Authors.

Multiband mucosectomy for advanced dysplastic lesions in the upper digestive tract
Espinel, Jesús; Pinedo, Eugenia; Ojeda, Vanesa; del Rio, Maria Guerra
2015-01-01
Endoscopic resection (ER) is at present an accepted treatment for superficial gastrointestinal neoplasia. ER provides similar efficacy to surgery; however, it is minimally invasive and less expensive. Endoscopic mucosal resection (EMR) is superior to biopsy for diagnosing advanced dysplasia and can change the diagnostic grade and the management. Several EMR techniques have been described that are alternatively used dependent upon the endoscopist personal experience, the anatomic conditions and the endoscopic appearance of the lesion to be resected. The literature suggests that EMR offers comparable outcomes to surgery for selected indications. EMR techniques using a cap fitted endoscope and EMR using a ligation device [multiband mucosectomy (MBM)] are the most frequently use. MBM technique does not require submucosal injection as with the endoscopic resection-cap technique, multiple resections can be performed with the same snare, pre-looping the endoscopic resection-snare in the ridge of the cap is not necessary, MBM does not require withdrawal of the endoscope between resections and up to six consecutive resections can be performed. This reduces the time and cost required for the procedure, while also reducing patient discomfort. Despite the increasing popularity of MBM, data on the safety and efficacy of this technique in upper gastrointestinal lesions with advanced dysplasia, defined as those lesions that have high-grade dysplasia or early cancer, is limited.

Nonvariceal upper gastrointestinal bleeding emerges as a major complication of using antiplatelet agents and/or anticoagulants and represents a clinical challenge in patients undergoing these therapies. To characterize patients with nonvariceal upper gastrointestinal bleeding related to antithrombotics and their management, and to determine clinical predictors of adverse outcomes. Retrospective cohort of adults who underwent upper gastrointestinal endoscopy after nonvariceal upper gastrointestinal bleeding from 2010 to 2012. The outcomes were compared between patients exposed and not exposed to antithrombotics. Five hundred and forty-eight patients with nonvariceal upper gastrointestinal bleeding (67% men; mean age 66.5 ± 16.4 years) were included, of which 43% received antithrombotics. Most patients had comorbidities. Peptic ulcer was the main diagnosis and endoscopic therapy was performed in 46% of cases. The 30-day mortality rate was 7.7% (n = 42), and 36% were bleeding-related. The recurrence rate was 9% and 14% of patients with initial endoscopic treatment needed endoscopic retreatment. There were no significant differences between the exposed and non-exposed groups in most outcomes. Co-morbidities, hemodynamic instability, high Rockall score, low hemoglobin (7.76 ± 2.72 g/dL) and higher international normalized ratio (1.63 ± 1.13) were associated significantly with mortality in a univariate analysis. Adverse outcomes were not associated with antithrombotic use. The management of nonvariceal upper gastrointestinal bleeding constitutes a challenge to clinical performance optimization and clinical cooperation.

The incidence of gastrointestinal disorders among patients with chronic kidney disease (CKD) is high, despite the lack of a good correlation between endoscopic findings and symptoms. Many services thus perform upper gastrointestinal (UGI) endoscopy on kidney transplant candidates. This study aims to describe the alterations seen on the upper endoscopies of 96 kidney-transplant candidates seen from 2014 to 2015. Ninety-six CKD patients underwent upper endoscopic examination as part of the preparation to receive kidney grafts. The data collected from the patients' medical records were charted on Microsoft Office Excel 2016 and presented descriptively. Mean values, medians, interquartile ranges and 95% confidence intervals of the clinic and epidemiological variables were calculated. Possible associations between endoscopic findings and infection by H. pylori were studied. Males accounted for 54.17% of the 96 patients included in the study. Median age and time on dialysis were 50 years and 50 months, respectively. The most frequent upper endoscopy finding was enanthematous pangastritis (57.30%), followed by erosive esophagitis (30.20%). Gastric intestinal metaplasia and peptic ulcer were found in 8.33% and 7.30% of the patients, respectively. H. pylori tests were positive in 49 patients, and H. pylori infection was correlated only with non-erosive esophagitis (P = 0.046). Abnormal upper endoscopy findings were detected in all studied patients. This study suggested that upper endoscopy is a valid procedure for kidney transplant candidates. However, prospective studies are needed to shed more light on this matter.

AIM: To prospectively assess the hemostatic efficacy of the endoscopic topical use of ankaferd blood stopper (ABS) in active non-variceal upper gastrointestinal system (GIS) bleeding. METHODS: Endoscopy was performed on 220 patients under suspiciency of GIS bleeding. Patients with active non-variceal upper gastrointestinal bleeding (NVUGIB) with a spurting or oozing type were included. Firstly, 8-10 cc of isotonic saline was sprayed to bleeding lesions. Then, 8 cc of ABS was applied on lesions in which bleeding continued after isotonic saline application. The other endoscopic therapeutic methods were applied on the lesions in which the bleeding did not stop after ABS. RESULTS: Twenty-seven patients had an active NVUGIB with a spurting or oozing type and 193 patients were excluded from the study since they did not have non-variceal active bleeding. 8 cc of ABS was sprayed on to the lesions of 26 patients whose bleeding continued after isotonic saline and in 19 of them, bleeding stopped after ABS. Other endoscopic treatment methods were applied to the remaining patients and the bleeding was stopped with these interventions in 6 of 7 patients. CONCLUSION: ABS is an effective method on NVUGIB, particularly on young patients with no coagulopathy. ABS may be considered as part of a combination treatment with other endoscopic methods.

Chronic gastritis in China: a national multi-center survey
2014-01-01
Background Chronic gastritis is one of the most common findings at upper endoscopy in the general population, and chronic atrophic gastritis is epidemiologically associated with the occurrence of gastric cancer. However, the current status of diagnosis and treatment of chronic gastritis in China is unclear. Methods A multi-center national study was performed; all patients who underwent diagnostic upper endoscopy for evaluation of gastrointestinal symptoms from 33 centers were enrolled. Data including sex, age, symptoms and endoscopic findings were prospectively recorded. Results Totally 8892 patients were included. At endoscopy, 4389, 3760 and 1573 patients were diagnosed to have superficial gastritis, erosive gastritis, and atrophic gastritis, respectively. After pathologic examination, it is found that atrophic gastritis, intestinal metaplasia and dysplasia were prevalent, which accounted for 25.8%, 23.6% and 7.3% of this patient population. Endoscopic features were useful for predicting pathologic atrophy (PLR = 4.78), but it was not useful for predicting erosive gastritis. Mucosal-protective agents and PPI were most commonly used medications for chronic gastritis. Conclusions The present study suggests non-atrophic gastritis is the most common endoscopic finding in Chinese patients with upper GI symptoms. Precancerous lesions, including atrophy, intestinal metaplasia and dysplasia are prevalent in Chinese patients with chronic gastritis, and endoscopic features are useful for predicting pathologic atrophy.

AIM: To study the preoperative and postoperative role of upper esophagogastroduodenoscopy (EGD) in morbidly obese patients. METHODS: This is a multicenter retrospective study by reviewing the database of patients who underwent bariatric surgery (laparoscopic sleeve gastrectomy, laparoscopic Roux en Y gastric bypass, or laparoscopic minigastric bypass) in the period between 2001 June and 2015 August (Jahra Hospital-Kuwait, Hafr Elbatin Hospital and King Saud Medical City-KSA, and Mansoura University Hospital - Egypt). Patients with age 18-65 years, body mass index (BMI) > 40, or > 35 with comorbidities after failure of many dietetic regimen and acceptable levels of surgical risk were included in the study after having an informed signed consent. We retrospectively reviewed the medical charts of all morbidly obese patients. The patients’ preoperative data included clinical history including upper digestive symptoms and preoperative full workup including EGD. Only patients whose charts revealed weather they were symptomatic or not were studied. We categorized patients accordingly into two groups; with (group A) or without (group B) upper digestive symptoms. The endoscopic findings were categorized into 4 groups based on predetermined criteria. The medical record of patients who developed stricture, leak or bleeding after bariatric surgery was reviewed. Logestic regression analysis was used to identify preoperative predictors that might be associated with abnormal endoscopic findings. RESULTS: Three thousand, two hundred and nineteen patients in the study period underwent bariatric surgery (75% LSG, 10% LRYDB, and 15% MGB). Mean BMI was 43 ± 13, mean age 37 ± 9 years, 79% were female. Twenty eight percent had presented with upper digestive symptoms (group A). EGD was considered normal in 2414 (75%) patients (9% group A vs 66% group B, P = 0.001). The abnormal endoscopic findings were found high in those patients with upper digestive symptoms. Abnormal findings (one or more) were found in 805 (25%) patients (19% group A vs 6% group B, P = 0.001). Seven patients had critical events during conscious sedation due to severe hypoxemia (< 60%). Rate of stricture in our study was 2.6%. Success rate of endoscopic dilation was 100%. One point nine percent patients with gastric leak were identified with 75% success rate of endoscopic therapy. Three point seven percent patients developed acute upper bleeding. Seventy-eight point two percent patients were treated by conservative therapy and EGD was performed in 21.8% with 100% success and 0% complications. CONCLUSION: Our results support the performance of EGD only in patients with upper gastrointestinal symptoms. Endoscopy also offers safe effective tool for anastomotic complications after bariatric surgery. PMID:27247708

The purpose of this study was to determine the prevalence of upper gastrointestinal tract lesions in children with human immunodeficiency virus (HIV) infection who undergo endoscopy of the upper gastrointestinal tract and to identify important clinical predictors of abnormal endoscopic results. All HIV-infected children who underwent endoscopy and were followed at Children's Hospital, Boston, from January 1985 to August 1994 were studied. The main outcome measure was endoscopic results, which were categorized into observational, histologic, and microbiologic findings. Potential predictors included height, weight, nutritional interventions, HIV disease stage, CD4 T-lymphocyte count, medications, active infections, and indications for endoscopy. Forty-three endoscopies in unique patients are reported. Most children had advanced HIV infection (67% acquired immunodeficiency syndrome, mean CD4 T-lymphocyte count z score = -2.71, weight z score = -2.04). An abnormal endoscopic finding was discovered in 93% of children and confirmed by histologic, microbiologic, or a combination of these studies in 72% of children. Thirty-five percent of children had an opportunistic pathogen identified endoscopically; 65% of these pathogens were previously undiagnosed. Observational findings often were poor indicators of histologic and microbiologic abnormalities. Independent predictors of abnormal histologic findings include younger age at endoscopy (odds ratio (OR) = 1.16 per year, 95% confidence interval (CI) (1.02, 1.33)) and guaiac-negative stools (OR = 16.7, 95% CI (1.92, 142.9)). Independent predictors of finding a pathogen at the time of endoscopy include a greater number of indications for endoscopy (OR = 2.6 per indication, 95% CI (1.3, 5.3)) and diagnosis of acquired immunodeficiency syndrome (OR = 16.4, 95% CI (1.3, 213)). No other gastrointestinal, nutritional, or immunologic parameters were significantly predictive of endoscopic outcomes. Medical management was changed in 70% of children because of the endoscopic findings. Endoscopy is a useful tool to direct therapy against peptic and infectious disorders of the upper gastrointestinal tract in children with HIV infection. Specific gastrointestinal symptoms are not useful predictors of abnormal results.

There is paucity of data as to the results of the endoscopic approach in comparison to the golden standard of nephro-ureterectomy in elective, low grade TCC, patients. Our purpose is to report our results of a nephron sparing approach compared to nephro-ureterectomy in those patients. From a retrospective data base we identified 25 patients and 23 patients who underwent a nephron sparing ureterosocpic resection and nephro-reterectomy for low grade UT-TCC, respectively. The endoscopic technique included endoscopic tumor biopsy followed by primary resection and/or fulguration. The nephron sparing group was followed by bi-annual ureteroscopy and upper tract imaging, timely cystoscopy and urine cytology collection. Data for overall and disease related mortality, bladder and ureteral TCC recurrence and renal function are reported in both groups. Median follow - up time was 26 months. 11 (44%) patients developed bladder recurrence at a median period of 9 months after initial ureteroscopy, compared to 9 (39%) in the NUx group (P < 0.05). Recurrent ureteral low grade TCC was observed in 9 patients (median: 9 months). All were treated endoscopicaly successfully. Renal function remained stable in the nephron sparing group. No disease related mortality was recorded in the nephron-sparing group while one patient died of his disease following NUx. Disease related mortality following a nephron sparing endoscopic approach or nephroureterectomy for low grade upper tract TCC is excellent. However, the nephron sparing approach is associated with a relatively high rate of ureteral and bladder recurrence. Therefore, a stringent follow-up protocol is required.

Upper gastrointestinal bleeding (UGIB) remains a common medical problem worldwide that has significant associated morbidity, mortality, and health care resource use. This study outlines the aetiology, clinical presentation, and treatment outcomes of patients with UGIB in a Nigerian low resource health facility. This was a descriptive study of consecutive patients who underwent upper gastrointestinal (GI) endoscopy for upper GI bleeding in the endoscopy unit of the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Osun State, Nigeria from January 2007 to December 2013. During the study period, 287 (12.4%) of 2,320 patients who underwent upper GI endoscopies had UGIB. Of these, 206 (72.0%) patients were males and their ages ranged from 3 to 100 years with a median age of 49 years. The main clinical presentation included passage of melaena stool in 268 (93.4%) of individuals, 173 (60.3%) had haematemesis, 110 (38.3%) had haematochezia, and 161 (56.1%) were dizzy at presentation. Observed in 88 (30.6%) of UGIB patients, duodenal ulcer was the most common cause, followed by varices [52 (18.1%)] and gastritis [51 (17.1%)]. For variceal bleeding, 15 (28.8%) and 21 (40.4%) of patients had injection sclerotherapy and variceal band ligation, respectively. The overall rebleeding rate for endoscopic therapy for varices was 16.7%. For patients with ulcers, only 42 of 55 who had Forrest grade Ia to IIb ulcers were offered endoscopic therapy. Endoscopic therapy was áin 90.5% of the cases. No rebleeding followed endoscopic therapy for the ulcers. The obtained Rockall scores ranged from 2 to 10 and the median was 5.0. Of all patients, 92.7% had medium or high risk scores. An increase in Rockall score was significantly associated with length of hospital stay and mortality (p < 0.001). The overall mortality rate was 5.9% (17 patients). Endoscopic therapy for UGIB in a resource-poor setting such as Nigeria is feasible, significantly reduces morbidity and mortality, and is cost effective. Efforts should be made to improve the accessibility of these therapeutic procedure for patients with UGIB in Nigeria.
Endoscopic Management of Tumor Bleeding from Inoperable Gastric Cancer
Kim, Young-Il
2015-01-01
Tumor bleeding is not a rare complication in patients with inoperable gastric cancer. Endoscopy has important roles in the diagnosis and primary treatment of tumor bleeding, similar to its roles in other non-variceal upper gastrointestinal bleeding cases. Although limited studies have been performed, endoscopic therapy has been highly successful in achieving initial hemostasis. One or a combination of endoscopic therapy modalities, such as injection therapy, mechanical therapy, or ablative therapy, can be used for hemostasis in patients with endoscopic stigmata of recent hemorrhage. However, rebleeding after successful hemostasis with endoscopic therapy frequently occurs. Endoscopic therapy may be a treatment option for successfully controlling this rebleeding. Transarterial embolization or palliative surgery should be considered when endoscopic therapy fails. For primary and secondary prevention of tumor bleeding, proton pump inhibitors can be prescribed, although their effectiveness to prevent bleeding remains to be investigated. PMID:25844339

AIM: To investigate the cooperative laparoscopic and endoscopic techniques used for the resection of upper gastrointestinal tumors. METHODS: A systematic research of the literature was performed in PubMed for English and French language articles about laparoscopic and endoscopic cooperative, combined, hybrid and rendezvous techniques. Only original studies using these techniques for the resection of early gastric cancer, benign tumors and gastrointestinal stromal tumors of the stomach and the duodenum were included. By excluding case series of less than 10 patients, 25 studies were identified. The study design, number of cases, tumor pathology size and location, the operative technique name, the endoscopy team and surgical team role, operative time, type of closure of visceral wall defect, blood loss, complications and length of hospital stay of these studies were evaluated. Additionally all cooperative techniques found were classified and are presented in a systematic approach. RESULTS: The studies identified were case series and retrospective cohort studies. A total of 706 patients were operated on with a cooperative technique. The tumors resected were only gastrointestinal stromal tumors (GIST) in 4 studies, GIST and various benign submucosal tumors in 22 studies, early gastric cancer (pT1a and pT1b) in 6 studies and early duodenal cancer in 1 study. There was important heterogeneity between the studies. The operative techniques identified were: laparoscopic assisted endoscopic resection, endoscopic assisted wedge resection, endoscopic assisted transgastric and intragastric surgery, laparoscopic endoscopic cooperative surgery (LECS), laparoscopic assisted endoscopic full thickness resection (LAEFR), clean non exposure technique and non-exposed endoscopic wall-inversion surgery (NEWS). Each technique is illustrated with the roles of the endoscopic and laparoscopic teams; the indications, characteristics and short term results are described. CONCLUSION: Along with the traditional cooperative techniques, new procedures like LECS, LAEFR and NEWS hold great promise for the future of minimally invasive oncologic procedures. PMID:26604655

Results MR sensitivity obtained at the depth of the TMS stimulation is increased by a factor of five. Parallel imaging with an acceleration factor of two is feasible with low g‐factors. Possible interactions between TMS and the novel hardware were investigated and were found negligible. Conclusion The novel coil array is safe, strongly improves signal‐to‐noise ratio in concurrent TMS/fMRI experiments, enables parallel imaging, and allows for flexible positioning of the TMS on the head while ensuring efficient TMS stimulation due to its ultraslim design.

We report our experience of endoscopy in the emergency management of dietary foreign bodies. One hundred thirty-six patients were admitted to the emergency department (ED) between January 1997 and October 2006 for the endoscopic removal of esophageal dietary foreign bodies. They had a mean age of 47.7 years, and 91 (67%) were women. Most of the ingested materials (98.5%) were successfully extracted using either flexible or rigid endoscope. The objects most frequently ingested were fish bones (48%) and chicken bones (46%). Most of the objects (84%) were lodged in the upper esophagus. Two patients with irretrievable foreign bodies or complicated perforations were taken to surgery. Because most of these foreign bodies lodged in the upper esophagus, physicians should take care of this area to avoid secondary injury or complications, especially with sharp bones.
Airway Management During Upper GI Endoscopic Procedures: State of the Art Review.
Goudra, Basavana; Singh, Preet Mohinder
2017-01-01
With the growing popularity of propofol mediated deep sedation for upper gastrointestinal (GI) endoscopic procedures, challenges are being felt and appreciated. Research suggests that management of the airway is anything but routine in this setting. Although many studies and meta-analyses have demonstrated the safety of propofol sedation administered by registered nurses under the supervision of gastroenterologists (likely related to the lighter degrees of sedation than those provided by anesthesia providers and is under medicolegal controversy in the United States), there is no agreement on the optimum airway management for procedures such as endoscopic retrograde cholangiopancreatography. Failure to rescue an airway at an appropriate time has led to disastrous consequences. Inability to evaluate and appreciate the risk factors for aspiration can ruin the day for both the patient and the health care providers. This review apprises the reader of various aspects of airway management relevant to the practice of sedation during upper GI endoscopy. New devices and modification of existing devices are discussed in detail. Recognizing the fact that appropriate monitoring is important for timely recognition and management of potential airway disasters, these issues are explored thoroughly.

Over the past two decades, transcatheter arterial embolization has become the first-line therapy for the management of upper gastrointestinal bleeding that is refractory to endoscopic hemostasis. Advances in catheter-based techniques and newer embolic agents, as well as recognition of the effectiveness of minimally invasive treatment options, have expanded the role of interventional radiology in the management of hemorrhage for a variety of indications, such as peptic ulcer bleeding, malignant disease, hemorrhagic Dieulafoy lesions and iatrogenic or trauma bleeding. Transcatheter interventions include the following: selective embolization of the feeding artery, sandwich coil occlusion of the gastroduodenal artery, blind or empiric embolization of the supposed bleeding vessel based on endoscopic findings and coil pseudoaneurysm or aneurysm embolization by three-dimensional sac packing with preservation of the parent artery. Transcatheter embolization is a fast, safe and effective, minimally invasive alternative to surgery when endoscopic treatment fails to control bleeding from the upper gastrointestinal tract. This article reviews the various transcatheter endovascular techniques and devices that are used in a variety of clinical scenarios for the management of hemorrhagic gastrointestinal emergencies.

Systemic embolism is an unusual complication of endoscopic obturation of gastroesophageal varices with glue. This report describes a case of cerebral embolism after this procedure. Intracardiac glue within the left atrium was demonstrated by echocardiography. Cardiac fluoroscopy demonstrated an abnormal vessel connecting periesophageal veins with the right upper pulmonary vein. Cardiac surgery was performed. Intracardiac glue was removed and the entering orifice of the abnormal vessel in the right upper pulmonary vein was sutured. To our knowledge, this is the first reported case of intracardiac glue after variceal obturation. Echocardiography is useful in the diagnosis of this rare complication.

Although the Vienna Classification recommends endoscopic resection for gastric high-grade dysplasia (HGD), many resected lesions are diagnosed as gastric cancer after endoscopic resection. This study aims to evaluate the clinical outcomes of gastric HGD identified by endoscopic forceps biopsy (EFB) after endoscopic submucosal dissection (ESD) and factors associated with discrepant results. From December 2008 to July 2015, a total of 427 lesions diagnosed as initial HGD by EFB were enrolled. The rate of early gastric cancer (EGC) and factors predicting diagnosis upgrade were analyzed retrospectively. Tumors ranged between 2 and 65 mm in size (median 12.59). En bloc and complete resection rates were 97.4 and 95.3%, respectively. The diagnostic discrepancy rate was 76.3%. Upgrade and downgrade rates of pathological diagnoses were 66.5 and 9.8%, respectively. Central depression (OR 4.151), nodular surface (OR 5.582), surface redness (OR 2.926), lesion location (upper third of the stomach) (OR 3.894), and tumor size ≥10 mm (OR 2.287) were significantly associated with EGC. Nodular surface (OR 2.746), submucosal fibrosis (OR 3.958), lesion location (upper third of the stomach) (OR 6.652), and tumor size ≥10 mm (OR 4.935) significantly predicted invasive submucosal cancer. Central depression, nodular surface, surface redness, lesion location, large tumor size, and submucosal fibrosis were associated with EGC or submucosal cancer. Caution must be used in treating lesions with these features with ESD.

Upper gastrointestinal bleeding (UGIB) is a common emergency medical condition that may require hospitalization and resuscitation, and results in high patient morbidity. Upper gastrointestinal endoscopy is the preferred investigative procedure for UGIB because of its accuracy, low rate of complication, and its potential for therapeutic interventions. To determine the endoscopic findings in patients presenting with UGIB and its frequency among these patients according to gender and age in Lacor hospital, northern Uganda. The study was carried out at Lacor hospital, located at northern part of Uganda. The record of 224 patients who underwent endoscopy for upper gastrointestinal bleeding over a period of 5 years between January 2006 and December 2010 were retrospectively analyzed. A total of 224 patients had endoscopy for UGIB which consisted of 113 (50.4%) males and 111 (49.6%) females, and the mean age was 42 years ± SD 15.88. The commonest cause of UGIB was esophagealvarices consisting of 40.6%, followed by esophagitis (14.7%), gastritis (12.6%) and peptic ulcer disease (duodenal and gastric ulcers) was 6.2%. The malignant conditions (gastric and esophageal cancers) contributed to 2.6%. Other less frequent causes of UGIB were hiatus hernia (1.8), duodenitis (0.9%), others-gastric polyp (0.4%). Normal endoscopic finding was 16.1% in patients who had UGIB. Esophageal varices are the commonest cause of upper gastrointestinal bleeding in this environment as compared to the west which is mainly peptic ulcer disease.

The management of upper gastrointestinal bleeding (UGIB) in anticoagulated patients with supratherapeutic international normalized ratios (INRs) presents a challenge. The purpose of the study was to evaluate the safety of endoscopic therapy for UGIB in anticoagulated patients with supratherapeutic INR in terms of rebleeding and therapeutic outcomes. One hundred ninety-two anticoagulated patients who underwent endoscopic treatment for UGIB were enrolled in the study. Patients were divided into 2 groups based on the occurrence of rebleeding within 30 days of the initial therapeutic endoscopy: no-rebleeding group (n = 168) and rebleeding group (n = 24). The overall rebleeding rate was 12.5%. Bleeding from gastric cancer and bleeding at the duodenum were significantly related to rebleeding in a univariate analysis. Multivariate analysis determined that presenting symptoms other than melena (hematemesis, hematochezia, or others) (odds ratio, 3.93; 95% confidence interval, 1.44-10.76) and bleeding from gastric cancer (odds ratio, 6.10; 95% confidence interval, 1.27-29.25) were significant factors predictive of rebleeding. Supratherapeutic INR at the time of endoscopic therapy was not significantly associated with rebleeding in either univariate or multivariate analysis. Significant differences in bleeding-related mortality, additional intervention to control bleeding, length of hospital stay, and transfusion requirements were revealed between the rebleeding and no-rebleeding groups. There were no significant differences in therapeutic outcomes between patients with INR within the therapeutic range and those with supratherapeutic INR. Supratherapeutic INR at the time of endoscopic therapy did not change rebleeding and therapeutic outcomes. Thus, we should consider endoscopic therapy for UGIB in anticoagulated patients, irrespective of INR at the time of endoscopic therapy.

Current development of endoscopic technology, lithotripters, and stone-retrieval devices has expanded the indications for retrograde and antegrade endoscopic therapy in the management of urolithiasis. This technology has also resulted in minimally invasive therapy. As surgeons' experience of endourological procedures with the newer instruments has become integrated, the surgical technique and indications for urolithiasis have also changed in the past few years. The present review provides an overview of endourological procedures for upper urinary tract stones and the key points related to surgical techniques. © 2017 The Japanese Urological Association.
Non-Exposure, Device-Assisted Endoscopic Full-thickness Resection.
Bauder, Markus; Schmidt, Arthur; Caca, Karel
2016-04-01
Recent developments have expanded the frontier of interventional endoscopy toward more extended resections following surgical principles. This article presents two new device-assisted techniques for endoscopic full-thickness resection in the upper and lower gastrointestinal tract. Both methods are nonexposure techniques avoiding exposure of gastrointestinal contents to the peritoneal cavity by a "close first-cut later" principle. The full-thickness resection device is a novel over-the-scope device designed for clip-assisted full-thickness resection of colorectal lesions. Endoscopic full-thickness resection of gastric subepithelial tumors can be performed after placing transmural sutures underneath the tumor with a suturing device originally designed for endoscopic antireflux therapy.

Gastrointestinal endoscopy in pregnancy
Savas, Nurten
2014-01-01
Gastrointestinal endoscopy has a major diagnostic and therapeutic role in most gastrointestinal disorders; however, limited information is available about clinical efficacy and safety in pregnant patients. The major risks of endoscopy during pregnancy include potential harm to the fetus because of hypoxia, premature labor, trauma and teratogenesis. In some cases, endoscopic procedures may be postponed until after delivery. When emergency or urgent indications are present, endoscopic procedures may be considered with some precautions. United States Food and Drug Administration category B drugs may be used in low doses. Endoscopic procedures during pregnancy may include upper gastrointestinal endoscopy, percutaneous endoscopic gastrostomy, sigmoidoscopy, colonoscopy, enteroscopy of the small bowel or video capsule endoscopy, endoscopic retrograde cholangiopancreatography and endoscopic ultrasonography. All gastrointestinal endoscopic procedures in pregnant patients should be performed in hospitals by expert endoscopists and an obstetrician should be informed about all endoscopic procedures. The endoscopy and flexible sigmoidoscopy may be safe for the fetus and pregnant patient, and may be performed during pregnancy when strong indications are present. Colonoscopy for pregnant patients may be considered for strong indications during the second trimester. Although therapeutic endoscopic retrograde cholangiopancreatography may be considered during pregnancy, this procedure should be performed only for strong indications and attempts should be made to minimize radiation exposure.

Acute Upper Gastrointestinal Bleeding is a common medical emergency with a hospital mortality of approximately 10 percent. Higher mortality rate is associated with rebleeding. Rockall scoring system identifies patients at higher risk of rebleed and mortality. To study the clinical and endoscopic profile of acute upper gastrointestinal bleed to know the etiology, clinical presentation, severity of bleeding and outcome. This is a prospective, descriptive hospital based study conducted in Gastroenterology unit of College of Medical Sciences and Teaching Hospital, Bharatpur, Nepal from January 2012 to January 2013. It included 120 patients at random presenting with manifestations of upper gastrointestinal bleed. Their clinical and endoscopic profiles were studied. Rockall scoring system was used to assess their prognosis. Males were predominant (75%). Age ranged from 14 to 88 years, mean being 48.76+17.19. At presentation 86 patients (71.7%) had both hematemesis and malena, 24 patients (20%) had only malena and 10 patients (8.3%) had only hematemesis. Shock was detected in 21.7%, severe anemia and high blood urea were found in 34.2% and 38.3% respectively. Upper Gastrointestinal Bleeding endoscopy revealed esophageal varices (47.5%), peptic ulcer disease (33.3%), erosive mucosal disease (11.6%), Mallory Weiss tear (4.1%) and malignancy (3.3%). Median hospital stay was 7.28+3.18 days. Comorbidities were present in 43.3%. Eighty six patients (71.7%) had Rockall score < 5 and 34 (28.3%) had >6. Five patients (4.2%) expired. Risk factors for death being massive rebleeeding, comorbidities and Rockall score >6. Acute Upper Gastrointestinal bleeding is a medical emergency. Mortality is associated with massive bleeding, comorbidities and Rockall score >6. Urgent, appropriate hospital management definitely helps to reduce morbidity and mortality.
Gallbladder Agenesis with Refractory Choledocholithiasis.
Tjaden, Jamie; Patel, Kevin; Aadam, Aziz
2015-01-01
Congenital agenesis of the gallbladder is a rare anomaly which is usually asymptomatic and found incidentally. In some cases, however, patients are symptomatic. Common symptoms include right upper quadrant abdominal pain, nausea, and vomiting. Jaundice is present in some symptomatic cases and is due to associated choledocholithiasis (Fiaschetti et al. 2009). In this case, a 63-year-old female presents with jaundice and episodic right upper quadrant abdominal pain with nausea and vomiting. Bilirubin and alkaline phosphatase were found to be markedly elevated. Upper endoscopic ultrasound (EUS) revealed choledocholithiasis, and the patient required multiple endoscopic retrograde cholangiopancreatography (ERCP) sessions before successful extraction of all stones. Subsequent surgical exploration revealed congenital agenesis of the gallbladder. Although this is a rare finding, patients with agenesis of the gallbladder are at increased risk of developing de novo choledocholithiasis which may be challenging to extract.
Potential capacity of endoscopic screening for gastric cancer in Japan.
Hamashima, Chisato; Goto, Rei
2017-01-01
In 2016, the Japanese government decided to introduce endoscopic screening for gastric cancer as a national program. To provide endoscopic screening nationwide, we estimated the proportion of increase in the number of endoscopic examinations with the introduction of endoscopic screening, based on a national survey. The total number of endoscopic examinations has increased, particularly in clinics. Based on the national survey, the total number of participants in gastric cancer screening was 3 784 967. If 30% of the participants are switched from radiographic screening to endoscopic screening, approximately 1 million additional endoscopic examinations are needed. In Japan, the participation rates in gastric cancer screening and the number of hospitals and clinics offering upper gastrointestinal endoscopy vary among the 47 prefectures. If the participation rates are high and the numbers of hospitals and clinics are small, the proportion of increase becomes larger. Based on the same assumption, 50% of big cities can provide endoscopic screening with a 5% increase in the total number of endoscopic examinations. However, 16.7% of the medical districts are available for endoscopic screening within a 5% increase in the total number of endoscopic examinations. Despite the Japanese government's decision to introduce endoscopic screening for gastric cancer nationwide, its immediate introduction remains difficult because of insufficient medical resources in rural areas. This implies that endoscopic screening will be initially introduced to big cities. To promote endoscopic screening for gastric cancer nationwide, the disparity of medical resources must first be resolved. © 2016 The Authors.

Upper gastrointestinal bleeding.
Feinman, Marcie; Haut, Elliott R
2014-02-01
Upper gastrointestinal (GI) bleeding remains a commonly encountered diagnosis for acute care surgeons. Initial stabilization and resuscitation of patients is imperative. Stable patients can have initiation of medical therapy and localization of the bleeding, whereas persistently unstable patients require emergent endoscopic or operative intervention. Minimally invasive techniques have surpassed surgery as the treatment of choice for most upper GI bleeding. Copyright © 2014 Elsevier Inc. All rights reserved.

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the diagnosis and management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). Main Recommendations MR1. ESGE recommends immediate assessment of hemodynamic status in patients who present with acute upper gastrointestinal hemorrhage (UGIH), with prompt intravascular volume replacement initially using crystalloid fluids if hemodynamic instability exists (strong recommendation, moderate quality evidence). MR2. ESGE recommends a restrictive red blood cell transfusion strategy that aims for a target hemoglobin between 7 g/dL and 9 g/dL. A higher target hemoglobin should be considered in patients with significant co-morbidity (e. g., ischemic cardiovascular disease) (strong recommendation, moderate quality evidence). MR3. ESGE recommends the use of the Glasgow-Blatchford Score (GBS) for pre-endoscopy risk stratification. Outpatients determined to be at very low risk, based upon a GBS score of 0 - 1, do not require early endoscopy nor hospital admission. Discharged patients should be informed of the risk of recurrent bleeding and be advised to maintain contact with the discharging hospital (strong recommendation, moderate quality evidence). MR4. ESGE recommends initiating high dose intravenous proton pump inhibitors (PPI), intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour), in patients presenting with acute UGIH awaiting upper endoscopy. However, PPI infusion should not delay the performance of early endoscopy (strong recommendation, high quality evidence). MR5. ESGE does not recommend the routine use of nasogastric or orogastric aspiration/lavage in patients presenting with acute UGIH (strong recommendation, moderate quality evidence). MR6. ESGE recommends intravenous erythromycin (single dose, 250 mg given 30 - 120 minutes prior to upper gastrointestinal [GI] endoscopy) in patients with clinically severe or ongoing active UGIH. In selected patients, pre-endoscopic infusion of erythromycin significantly improves endoscopic visualization, reduces the need for second-look endoscopy, decreases the number of units of blood transfused, and reduces duration of hospital stay (strong recommendation, high quality evidence). MR7. Following hemodynamic resuscitation, ESGE recommends early (≤ 24 hours) upper GI endoscopy. Very early (< 12 hours) upper GI endoscopy may be considered in patients with high risk clinical features, namely: hemodynamic instability (tachycardia, hypotension) that persists despite ongoing attempts at volume resuscitation; in-hospital bloody emesis/nasogastric aspirate; or contraindication to the interruption of anticoagulation (strong recommendation, moderate quality evidence). MR8. ESGE recommends that peptic ulcers with spurting or oozing bleeding (Forrest classification Ia and Ib, respectively) or with a nonbleeding visible vessel (Forrest classification IIa) receive endoscopic hemostasis because these lesions are at high risk for persistent bleeding or rebleeding (strong recommendation, high quality evidence). MR9. ESGE recommends that peptic ulcers with an adherent clot (Forrest classification IIb) be considered for endoscopic clot removal. Once the clot is removed, any identified underlying active bleeding (Forrest classification Ia or Ib) or nonbleeding visible vessel (Forrest classification IIa) should receive endoscopic hemostasis (weak recommendation, moderate quality evidence). MR10. In patients with peptic ulcers having a flat pigmented spot (Forrest classification IIc) or clean base (Forrest classification III), ESGE does not recommend endoscopic hemostasis as these stigmata present a low risk of recurrent bleeding. In selected clinical settings, these patients may be discharged to home on standard PPI therapy, e. g., oral PPI once-daily (strong recommendation, moderate quality evidence). MR11. ESGE recommends that epinephrine injection therapy not be used as endoscopic monotherapy. If used, it should be combined with a second endoscopic hemostasis modality (strong recommendation, high quality evidence). MR12. ESGE recommends PPI therapy for patients who receive endoscopic hemostasis and for patients with adherent clot not receiving endoscopic hemostasis. PPI therapy should be high dose and administered as an intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour) for 72 hours post endoscopy (strong recommendation, high quality evidence). MR13. ESGE does not recommend routine second-look endoscopy as part of the management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). However, in patients with clinical evidence of rebleeding following successful initial endoscopic hemostasis, ESGE recommends repeat upper endoscopy with hemostasis if indicated. In the case of failure of this second attempt at hemostasis, transcatheter angiographic embolization (TAE) or surgery should be considered (strong recommendation, high quality evidence). MR14. In patients with NVUGIH secondary to peptic ulcer, ESGE recommends investigating for the presence of Helicobacter pylori in the acute setting with initiation of appropriate antibiotic therapy when H. pylori is detected. Re-testing for H. pylori should be performed in those patients with a negative test in the acute setting. Documentation of successful H. pylori eradication is recommended (strong recommendation, high quality evidence). MR15. In patients receiving low dose aspirin for secondary cardiovascular prophylaxis who develop peptic ulcer bleeding, ESGE recommends aspirin be resumed immediately following index endoscopy if the risk of rebleeding is low (e. g., FIIc, FIII). In patients with high risk peptic ulcer (FIa, FIb, FIIa, FIIb), early reintroduction of aspirin by day 3 after index endoscopy is recommended, provided that adequate hemostasis has been established (strong recommendation, moderate quality evidence). © Georg Thieme Verlag KG Stuttgart · New York.

Reporting our institutional experience with high-flow nasal oxygen therapy (HFNOT), a recently-introduced technique, for endoscopic airway approaches. Prospective collection of data of children (<16 years) undergoing endoscopic between January 2016 and August 2017 at a tertiary referral university hospital. HFNOT was used in 6 children who underwent 14 procedures for different forms and causes of upper airway obstruction of various origins. No intraoperative complications; related to oxygenation were observed, and the surgical procedures could be carried out as; initially planned. We found that HFNOT is an effective and safe technique with a variety of potential applications in the field of endoscopic pediatric airway surgery. Copyright © 2018 Elsevier B.V.

A Review of Endoscopic Simulation: Current Evidence on Simulators and Curricula.
King, Neil; Kunac, Anastasia; Merchant, Aziz M
2016-01-01
Upper and lower endoscopy is an important tool that is being utilized more frequently by general surgeons. Training in therapeutic endoscopic techniques has become a mandatory requirement for general surgery residency programs in the United States. The Fundamentals of Endoscopic Surgery has been developed to train and assess competency in these advanced techniques. Simulation has been shown to increase the skill and learning curve of trainees in other surgical disciplines. Several types of endoscopy simulators are commercially available; mechanical trainers, animal based, and virtual reality or computer-based simulators all have their benefits and limitations. However they have all been shown to improve trainee's endoscopic skills. Endoscopic simulators will play a critical role as part of a comprehensive curriculum designed to train the next generation of surgeons. We reviewed recent literature related to the various types of endoscopic simulators and their use in an educational curriculum, and discuss the relevant findings.

[Prediction of the efficiency of endoscopic lung volume reduction by valves in severe emphysema].
Bocquillon, V; Briault, A; Reymond, E; Arbib, F; Jankowski, A; Ferretti, G; Pison, C
2016-11-01
In severe emphysema, endoscopic lung volume reduction with valves is an alternative to surgery with less morbidity and mortality. In 2015, selection of patients who will respond to this technique is based on emphysema heterogeneity, a complete fissure visible on the CT-scan and absence of collateral ventilation between lobes. Our case report highlights that individualized prediction is possible. A 58-year-old woman had severe, disabling pulmonary emphysema. A high resolution thoracic computed tomography scan showed that the emphysema was heterogeneous, predominantly in the upper lobes, integrity of the left greater fissure and no collateral ventilation with the left lower lobe. A valve was inserted in the left upper lobe bronchus. At one year, clinical and functional benefits were significant with complete atelectasis of the treated lobe. The success of endoscopic lung volume reduction with a valve can be predicted, an example of personalized medicine. Copyright © 2016 SPLF. Published by Elsevier Masson SAS. All rights reserved.

1992-12-01
Endoscopy is extremely useful for the diagnosis of upper gastrointestinal bleeding. At the present time, therapeutic measures are been used during the endoscopy to stop bleeding. This paper reports the experience of hospital de Talca in the endoscopic treatment of upper gastrointestinal bleeding. Thirty four patients (22 male) with bleeding not originating from esophageal or gastric varices were treated with direct absolute alcohol injection into the bleeding lesions. The procedure was successful in 31 patients. Three of the 34 patients required surgery, but only one of those successfully sclerosed (97% success). There were no complications attributable to the procedure. It is concluded that this therapeutic modality must be implemented in places were gastrointestinal endoscopy is performed.
Review of Pure Endoscopic Full-Thickness Resection of the Upper Gastrointestinal Tract
Mori, Hirohito; Kobara, Hideki; Nishiyama, Noriko; Fujihara, Shintaro; Masaki, Tsutomu
2015-01-01
Natural-orifice transluminal endoscopic surgery (NOTES) using flexible endoscopy has attracted attention as a minimally invasive surgical method that does not cause an operative wound on the body surface. However, minimizing the number of devices involved in endoscopic, compared to laparoscopic, surgeries has remained a challenge, causing endoscopic surgeries to gradually be phased out of use. If a flexible endoscopic full-thickness suturing device and a counter-traction device were developed to expand the surgical field for gastrointestinal-tract collapse, then endoscopic full-thickness resection using NOTES, which is seen as an extension of endoscopic submucosal dissection for full-thickness excision of tumors involving the gastrointestinal-tract wall, might become an extremely minimally invasive surgical method that could be used to resect only full-thickness lesions approached by the shortest distance via the mouth. It is expected that gastroenterological endoscopists will use this surgery if device development is advanced. This extremely minimally invasive surgery would have an immeasurable impact with regard to mitigating the burden on patients and reducing healthcare costs. Development of a new surgical method using a multipurpose flexible endoscope is therefore considered a socially urgent issue. PMID:26343069

Mallory-Weiss syndrome (MWS) accounts for 6-14% of all cases of upper gastrointestinal bleeding. Prognosis of patients with MWS is generally good, with a benign course and rare recurrence of bleeding. However, no strict recommendations exist in regard to the mode of action after a failure of primary endoscopic hemostasis. We report a case of an 83-year-old male with MWS and rebleeding after the initial endoscopic treatment with epinephrine and clips. The final endoscopic control of bleeding was achieved by a combined application of clips and a nylon snare in a "tulip-bundle" fashion. The patient had an uneventful postprocedural clinical course and was discharged from the hospital five days later. To the best of our knowledge, this is the first case report showing the "tulip-bundle" technique as a rescue endoscopic bleeding control in the esophagus.

Minimally invasive surgical techniques expose surgeons to a variety of occupational hazards that may promote musculoskeletal disorders. Telerobotic systems for minimally invasive surgery may help to reduce these stressors. The objective of this study was to compare manual and telerobotic endoscopic surgery in terms of postural and mental stress. Thirteen participants with no experience as primary surgeons in endoscopic surgery performed a set of simulated surgical tasks using two different techniques--a telerobotic master--slave system and a manual endoscopic surgery system. The tasks consisted of passing a soft spherical object through a series of parallel rings, suturing along a line 5-cm long, running a 32-in ribbon, and cannulation. The Job Strain Index (JSI) and Rapid Upper Limb Assessment (RULA) were used to quantify upper extremity exposure to postural and force risk factors. Task duration was quantified in seconds. A questionnaire provided measures of the participants' intuitiveness and mental stress. The JSI and RULA scores for all four tasks were significantly lower for the telerobotic technique than for the manual one. Task duration was significantly longer for telerobotic than for manual tasks. Participants reported that the telerobotic technique was as intuitive as, and no more stressful than, the manual technique. Given identical tasks, the time to completion is longer using the telerobotic technique than its manual counterpart. For the given simulated tasks in the laboratory setting, the better scores for the upper extremity postural analysis indicate that telerobotic surgery provides a more comfortable environment for the surgeon without any additional mental stress.

In Korea, the nationwide gastric cancer screening program recommends biennial screening for individuals aged 40 years or older by way of either an upper gastrointestinal series or endoscopy. The national endoscopic quality assessment (QA) program began recommending endoscopy in medical institutions in 2009. We aimed to assess the effect, burden, and cost of the QA program from the viewpoint of medical institutions. We surveyed the staff of institutional endoscopic units via e-mail. Staff members from 67 institutions replied. Most doctors were endoscopic specialists. They responded as to whether the QA program raised awareness for endoscopic quality (93%) or improved endoscopic practice (40%). The percentages of responders who reported improvements in the diagnosis of gastric cancer, the qualifications of endoscopists, the quality of facilities and equipment, endoscopic procedure, and endoscopic reprocessing were 69%, 60%, 66%, 82%, and 75%, respectively. Regarding reprocessing, many staff members reported that they had bought new automated endoscopic preprocessors (3%), used more disinfectants (34%), washed endoscopes longer (28%), reduced the number of endoscopies performed to adhere to reprocessing guidelines (9%), and created their own quality education programs (59%). Many responders said they felt that QA was associated with some degree of burden (48%), especially financial burden caused by purchasing new equipment. Reasonable quality standards (45%) and incentives (38%) were considered important to the success of the QA program. Endoscopic quality has improved after 5 years of the mandatory endoscopic QA program.

Atelectasis is one of the pulmonary complications associated with anesthesia. Little is known about atelectasis following endoscopic procedures under deep sedation. This study evaluated the frequency, risk factors, and clinical course of atelectasis after endoscopic resection. A total of 349 patients who underwent endoscopic resection of the upper gastrointestinal tract at a single academic tertiary referral center from March 2010 to October 2013 were enrolled. Baseline characteristics and clinical data were retrospectively reviewed from medical records. To identify atelectasis, we compared the chest radiography taken before and after the endoscopic procedure. Among the 349 patients, 68 (19.5 %) had newly developed atelectasis following endoscopic resection. In univariate logistic regression analysis, atelectasis correlated significantly with high body mass index, smoking, diabetes mellitus, procedure duration, size of lesion, and total amount of propofol. In multiple logistic regression analysis, body mass index, procedure duration, and total propofol amount were risk factors for atelectasis following endoscopic procedures. Of the 68 patients with atelectasis, nine patients developed fever, and six patients displayed pneumonic infiltration. The others had no symptoms related to atelectasis. The incidence of radiographic atelectasis following endoscopic resection was nearly 20 %. Obesity, procedural time, and amount of propofol were the significant risk factors for atelectasis following endoscopic procedure. Most cases of the atelectasis resolved spontaneously with no sequelae.

Ingested foreign bodies and food bolus impaction are frequently seen in endoscopic practice. Successful foreign body and food bolus removal may depend on the method used, the choice of device, and the experience level of the endoscopist, although few papers report experience and outcome of tertiary centers. To investigate the effectiveness of our protocol designed for removal of ingested foreign bodies and food boluses. We retrospectively reviewed all patients with a diagnosis of foreign body ingestion and food bolus impaction from 1994 to 2005 identified by computer search. Patients were excluded if medical record was incomplete. The analysis included 171 patients. Foreign bodies and impacted food boluses were found in 77 and 62 patients, respectively. In 32 cases (23%), the foreign bodies passed spontaneously through the gastrointestinal tract. The overall success rate for endoscopic management was obtained in 137 patients (98.6%). Surgical removal of a foreign body was required in only 2 cases (1.4%). According to the type and location of the foreign object and food bolus we used Dormia baskets, retrieval forceps, polypectomy snares, and all sizes of Roth net. No complications relating to the endoscopic procedure were observed; 50 patients (35.2%) had an underlying esophageal disease. Endoscopic removal of upper gastrointestinal tract foreign bodies and food bolus impaction is efficacious and safe. Especially the Roth net is the best device for safe retrieval of food boluses and button disc batteries.

To investigate upper respiratory tract function in horses, previously undergoing laryngoplasty (LP), using exercising video-endoscopy. To evaluate arytenoid abduction and stability, diagnose any concurrent upper airway problems, and correlate these with the owners' perception of success. Horses undergoing LP during a 6-year period at one hospital were initially included. Those available for re-examination were exercised for a duration and intensity considered maximal for their discipline using an over-ground endoscope. Resting and exercising laryngeal and pharyngeal videos were analysed blindly. Multivariable analysis was used to test associations between resting and exercising endoscopic variables, and also between endoscopic variables and owner questionnaire findings. Forty-one horses were included and 78% had a form of upper airway collapse at exercise, with 41% having complex forms, despite 93% of owners reporting the surgery to have been beneficial. Horses with poor abduction (grades 4 or 5/5) were 6 times more likely to make respiratory noise compared with those with good (grades 2 or 3/5) abduction (P = 0.020; 95% confidence interval [CI] 1.3-27.0), and those not having a ventriculectomy were 4.9 times more likely to produce respiratory noise post operatively (P = 0.048; 95% CI 1.0-23.9). Palatal dysfunction was observed in 24% of horses at rest, and 56% at exercise, with the diagnosis at rest and exercise significantly associated (P = 0.001). Increasing severity of pharyngeal lymphoid hyperplasia (prevalence 61%) was significantly associated with increasing arytenoid abduction (P = 0.01). Thirty-four per cent of horses had aryepiglottic fold collapse and 22% of horses had vocal fold collapse. Many horses that had previously had LP were diagnosed with upper airway abnormalities, despite the procedure being considered as beneficial by most owners. When investigating cases of ongoing respiratory noise or poor performance following LP, exercising endoscopy must be considered. Continued respiratory noise may be associated with poor arytenoid abduction and not performing concurrent ventriculectomy. © 2012 EVJ Ltd.

Every gastrointestinal bleeding is an immediate threat to life, requiring close supervision in a hospital setting and making it mandatory to perform verification and endoscopic intervention. In some cases of a dynamic course, in order to make up deficiencies, it is necessary to use blood and blood products. One of the causes of bleeding located proximally to the ligament of Treitz is damage to the mucous membrane and deeper layers of the gastroesophageal junction, called Mallory-Weiss syndrome. The aim of the study was retrospective analysis of a selected group of patients with symptomatic upper gastrointestinal bleeding in the course of Mallory-Weiss syndrome, identification of typical characteristics of this disease entity in the studied population as well as demonstration of the effectiveness of endoscopic treatment using argon plasma coagulation (APC). The analysis included 2120 gastroscopy results, with 111 (5.24%) examinations conducted due to symptomatic gastrointestinal bleeding. In the studied group, endoscopic diagnosis of Mallory-Weiss syndrome was made in 22 patients (1.04%). The studied disease entity was the cause of upper gastrointestinal bleeding in 19.82% of cases. Although this condition is usually characterised by a mild and self-limiting course, 59.09% of patients in the studied group required therapeutic endoscopic intervention due to active bleeding. In 54.55%, argon plasma coagulation was successfully used to control the source of bleeding. Early gastroscopy, which remains both a diagnostic and therapeutic intervention, guarantees effective control of the clinical course of Mallory-Weiss syndrome. Endoscopic argon plasma coagulation is an effective way to treat bleeding, used in endoscopic monotherapy or in combination with other procedures.

Current capsule endoscopy procedures are ineffective for upper gastrointestinal (GI) tract examination because they do not allow for operator-controlled navigation of the capsule. External controllability of a capsule endoscope with an applied magnetic field is a possible solution to this problem. We developed a novel magnetic-assisted capsule endoscope (MACE) system to visualize the entire upper GI tract. The present study evaluated the safety and feasibility of the MACE system for the examination of the upper GI tract, including the esophagus, stomach, and duodenum. The present open clinical study enrolled ten healthy volunteers. All participants swallowed a MACE, and an external magnetic field navigator was used for magnetic capsule manipulation in the upper GI tract. We assessed the maneuverability of the magnetic capsule and completeness of the MACE examination as well as the safety and tolerability of the procedure. The present study enrolled ten healthy volunteers with a mean age and body mass index of 47.7 years and 25.6 kg/m 2 , respectively. One volunteer withdrew because of difficulty in swallowing the capsule. In total, nine volunteers underwent the MACE examination. The average examination time was 27.1 min. The maneuverability of the capsule was assessed as good and fair in 55.6 and 44.4% of the participants, respectively. The overall completeness of the examination in the esophagus, stomach, and duodenum was 100, 85.2, and 86.1%, respectively. No severe adverse events occurred during this study. All participants exhibited satisfactory tolerance of the MACE examination. The MACE system has satisfactory maneuverability and visualization completeness with excellent acceptance and tolerance.

Peptic ulcers are the leading cause of upper gastrointestinal (GI) bleeding. The aim of this study was the evaluation of the recent clinical practice in drug therapy and endoscopic treatment of ulcer bleedings in Germany and to compare the results with the medical standard. A structured questionnaire (cross-sectional study) was sent to 1371 German hospitals that provide an emergency service for upper GI bleeding. The project was designed similar to a nationwide inquiry in France in 2001. Forty-four questions concerning the following topics were asked: hospital organisation, organisation of emergency endoscopy service, endoscopic and drug therapy of ulcer bleeding, endoscopic treatment of variceal bleeding. Return of the questionnaires was closed in August 2004. Response rate was 675 / 1371 (49 %). Mean hospitals size was < 200 beds, 49 % (n = 325) had basic care level. 92 % provided a 24-hour endoscopy service, specialized nurses were available in 75 %. Fiberscopes were used only in 15 %. A mean of 10 +/- 12 (range: 0 - 160) bleeding cases/month were treated, 6 +/- 6 cases per month (60 %) were ulcer bleedings. Endoscopy was performed in 72 % immediately after stabilization but in all cases within 24 hours. The Forrest classification was used in 99 % whereas prognostic scores were applied only in 3 %. Forrest Ia,/Ib/IIa/IIb/IIc/III ulcers were indications for endoscopic therapy in 99 %/ 99 %/ 90 %/ 58 %/ 4 %/ 2 % respectively. Favoured initial treatment was injection (diluted epinephrine, mean volume 17 +/- 13 mL/lesion) followed by clipping. In re-bleedings, 93 % tried endoscopic treatment again. Scheduled re-endoscopy was performed in 63 %. PPI were used in 99.6 %, 85 % administered standard dose twice daily. PPI administration was changed from intravenous to oral with the end of fasting in nearly all hospitals. PPI administration schemes can be improved. Indications for Helicobacter pylori eradication followed rational principles. Medical and endoscopic treatment of bleeding ulcers reached a high standard, although some therapeutic strategies leave room for improvement. Bigger hospitals tend to be closer to the medical standard.
Upper gastrointestinal bleeding - state of the art.
Szura, Mirosław; Pasternak, Artur
2014-01-01
Upper gastrointestinal (GI) bleeding is a condition requiring immediate medical intervention, with high associated mortality exceeding 10%. The most common cause of upper GI bleeding is peptic ulcer disease, which largely corresponds to the intake of NSAIDs and Helicobacter pylori infection. Endoscopy is the essential tool for the diagnosis and treatment of active upper GI hemorrhage. Endoscopic therapy together with proton pump inhibitors and eradication of Helicobacter pylori significantly reduces rebleeding rates, mortality and number of emergency surgical interventions. This paper presents contemporary data on the diagnosis and treatment of upper gastrointestinal bleeding.

This is the first report which describes carbon dioxide laser photocoagulation of upper gastrointestinal bleeding via a flexible endoscope, using an infrared transmitting siver nalide fiber. Various laser parameters were checked to determine the optimal conditions for hemostasis. Both the acute effects of laser irradiation on tissue and the chronic effects on healing process were examined. Preliminary results indicate that carbon dioxide laser beam can successfully photocoagulate moderately bleeding ulcers.

There exists a complex interplay between asthma and gastroesophageal reflux disease. Both these diseases are known to aggravate each other and amelioration of one is necessary for the control of the other. There is a paucity of studies in Indian population on this subject. To evaluate the clinical features and the endoscopic findings of the upper gastrointestinal tract in patients with bronchial asthma. Study was conducted at KMC group of hospitals, Mangalore in the Department of chest medicine in association with Department of gastroenterology. Subjects included 50 cases of bronchial asthma and controls were 58 non asthmatic patients with allergic rhinitis and chronic urticaria. All patients were queried about presence or absence of symptoms of upper gastro intestinal tract disorders by gastro oesophageal reflux disease (GERD) questionnaire and all the included patients underwent upper gastro intestinal endoscopy. The study showed that symptoms of gastroesophageal reflux were significantly more in asthmatics (52%) as compared to the controls (28%). The common presenting features of gastroesophageal reflux in asthmatics were heartburn (40%) retrosternal pain (24%), nocturnal cough (18%), dyspepsia (16%) and regurgitation (14%) and the above symptoms were significantly more common in asthmatics as compared to controls. Gastroesophageal reflux disease was found to be significantly more common in the asthmatics (58%) as compared to the control group where it was present in 32.75% of the subjects. Clinical or endoscopic evidence of any upper gastrointestinal disorder was found in 68% of the asthmatics as compared to 37.93% of the controls. This difference was found to be statistically significant. The study showed that gastroesophageal reflux disease was significantly more in asthmatics as compared to the controls. Upper gastrointestinal symptoms were more common in asthmatics as against controls. Clinical or endoscopic evidence of upper gastrointestinal disorder and gastroesophageal reflux disease was found in significantly higher proportion of the asthmatics as compared to the controls. Clinically silent gastroesophageal reflux disease was however seen in both control and asthmatic groups equally with a lower prevalence.
Iron-deficiency anemia as a subclinical celiac disease presentation in an Argentinian population.
Lasa, J S; Olivera, P; Soifer, L; Moore, R
There is a wide heterogeneity in the reports of celiac disease prevalence in iron-deficiency anemia patients. To determine the prevalence of celiac disease in patients with iron-deficiency anemia. Adult patients with a diagnosis of iron-deficiency anemia were enrolled for upper endoscopy with duodenal biopsies. Healthy volunteers that underwent upper endoscopy were enrolled as controls. A total of 135 patients with iron-deficiency anemia and 133 controls were enrolled. Celiac disease prevalence was higher in the iron-deficiency anemia group [11.11 vs. 1.51%, OR: 8.18 (1.83-36.55), P=.001). Of the celiac disease patients in the iron-deficiency anemia group, 73.3% had at least one endoscopic sign suggesting villous atrophy, whereas 100% of the celiac disease patients in the control group presented with at least one endoscopic sign. Patients with iron-deficiency anemia have an increased risk for celiac disease. Up to 25% of these patients may not present any endoscopic sign suggesting villous atrophy.

The purpose of this study was to identify endoscopic and clinical parameters influencing the decision-making in salvage of endoscopically unmanageable, nonvariceal upper gastrointestinal hemorrhage (UGIH) and to report the outcome of selected therapy. We retrospectively retrieved all cases of surgery and arteriography for arrest of endoscopically unmanageable UGIH. Only patients with overt bleeding on endoscopy within the previous 24 h were included. Patients with preceding nonendoscopic hemostatic interventions, portal hypertension, malignancy, and transpapillar bleeding were excluded. Potential clinical and endoscopic predictors of allocation to either surgery or arteriography were tested using statistical models. Outcome and survival were regressed on themore » choice of rescue and clinical variables. Forty-six arteriographed and 51 operated patients met the inclusion criteria. Univariate analysis revealed a higher number of patients with a coagulation disorder in the catheterization group (41.4%, versus 20.4% in the laparotomy group; p = 0.044). With multivariate analysis, the identification of a bleeding peptic ulcer at endoscopy significantly steered decision-making toward surgical rescue (OR = 5.2; p = 0.021). Taking into account reinterventions, hemostasis was achieved in nearly 90% of cases in both groups. Overall therapy failure (no survivors), rebleeding within 3 days (OR = 3.7; p = 0.042), and corticosteroid use (OR = 5.2; p = 0.017) had a significant negative impact on survival. The odds of dying were not different for embolotherapy or surgery. In conclusion, decision-making was endoscopy-based, with bleeding peptic ulcer significantly directing the choice of rescue toward surgery. Unsuccessful hemostasis and corticosteroid use, but not the choice of rescue, negatively affected outcome.« less

Endoscopic hemoclip application is an effective and safe method of endoscopic hemostasis. We conducted a multicenter retrospective study on hemoclip and hemoclip combination therapy based on prospective cohort database in terms of hemostatic efficacy not in clinical trial but in real clinical practice. Data on endoscopic hemostasis for non-variceal upper gastrointestinal bleeding (NVUGIB) were prospectively collected from February 2011 to December 2013. Among 1,584 patients with NVUGIB, 186 patients treated with hemoclip were enrolled in this study. Subjects were divided into three groups: Group 1 (n = 62), hemoclipping only; group 2 (n = 88), hemoclipping plus epinephrine injection; and group 3 (n = 36), hemocliping and epinephrine injection plus other endoscopic hemostatic modalities. Primary outcomes included rebleeding, other therapeutic management, hospitalization period, fasting period and mortality. Secondary outcomes were bleeding associated mortality and overall mortality. Active bleeding and peptic ulcer bleeding were more common in group 3 than in group 1 and in group 2 (p < 0.001). However, primary outcomes (rebleeding, other management, morbidity, hospitalization period, fasting period and mortality) and secondary outcomes (bleeding associated mortality and total mortality) were not different among groups. Combination therapy of epinephrine injection and other modalities with hemoclips did not show advantage over hemoclipping alone in this prospective cohort study. However, there is a tendency to perform combination therapy in active bleeding which resulted in equivalent hemostatic success rate, and this reflects the role of combination therapy in clinical practice.
Endoscopic removal of over-the-scope clips: Clinical experience with a bipolar cutting device
Meier, Benjamin; Caca, Karel; Schmidt, Arthur
2016-01-01
Background Over-the-scope clips (OTSCs) are increasingly used for the closure of perforations/fistulae, hemostasis and endoscopic full-thickness resection (FTRD system). When OTSC-associated complications occur or re-therapy at the OTSC site is needed, OTSC removal may be indicated. An experimental study in an animal model and a case series have shown good results for OTSC removal with a bipolar cutting device. We present a larger clinical study using this device. Methods Data of all consecutive patients with indication for OTSC removal were collected and analyzed retrospectively. OTSCs were cut at two opposing sites using a bipolar grasping device to apply short direct current impulses. OTSC fragments were extracted with a standard forceps and a cap at the tip of the endoscope to avoid tissue damage. Results Between December 2012 and February 2016 a total of 42 OTSC removals in the upper (n = 25) and lower (n = 17) gastrointestinal tract have been performed at our department. Overall technical success, defined as cutting the OTSC at two opposing sites and extraction of both fragments, was achieved in 92.9% (39/42) of all cases. Successful fragmentation of the OTSC was achieved in 97.6% (41/42). Minor bleedings were rare and could be managed endoscopically in all cases. There were no perforations and no major or delayed bleedings. Conclusion Endoscopic OTSC removal with a bipolar cutting device is feasible, effective and safe. This technique can be applied in the upper and lower gastrointestinal tract. PMID:28588877

Acute nonvariceal upper gastrointestinal (UGI) hemorrhage is a frequent complication associated with significant morbidity and mortality. The most common cause of UGI bleeding is peptic ulcer disease, but the differential diagnosis is diverse and includes tumors; ischemia; gastritis; arteriovenous malformations, such as Dieulafoy lesions; Mallory-Weiss tears; trauma; and iatrogenic causes. Aggressive treatment with early endoscopic hemostasis is essential for a favorable outcome. However, severe bleeding despite conservative medical treatment or endoscopic intervention occurs in 5-10% of patients, requiring surgery or transcatheter arterial embolization. Surgical intervention is usually an expeditious and gratifying endeavor, but it can be associated with high operativemore » mortality rates. Endovascular management using superselective catheterization of the culprit vessel, < sandwich> occlusion, or blind embolization has emerged as an alternative to emergent operative intervention for high-risk patients and is now considered the first-line therapy for massive UGI bleeding refractory to endoscopic treatment. Indeed, many published studies have confirmed the feasibility of this approach and its high technical and clinical success rates, which range from 69 to 100% and from 63 to 97%, respectively, even if the choice of the best embolic agent among coils, cyanaocrylate glue, gelatin sponge, or calibrated particles remains a matter of debate. However, factors influencing clinical outcome, especially predictors of early rebleeding, are poorly understood, and few studies have addressed this issue. This review of the literature will attempt to define the role of embolotherapy for acute nonvariceal UGI hemorrhage that fails to respond to endoscopic hemostasis and to summarize data on factors predicting angiographic and embolization failure.« less

Peptic ulcer bleeding is treated using endoscopic hemostasis using clips or bands. Pancreas divisum (PD), a congenital anomaly of the pancreas, usually has no clinical symptoms; however, pancreatitis may occur if there are disturbances in the drainage of pancreatic secretions. We report an unusual case of PD accompanied by acute pancreatitis, following endoscopic band ligation for duodenal ulcer bleeding. A 48-year-old woman was admitted to our hospital due to melena. An upper endoscopy revealed a small ulcer with oozing adjacent minor papilla. An endoscopic band ligation was performed on this lesion. Acute pancreatitis developed suddenly 6 hours after the band ligation and improved dramatically after removal of the band. Magnetic resonance cholangiopancreatography was performed, revealing complete PD. Endoscopic band ligation is known as the effective method for peptic ulcer bleeding; however, it should be used carefully in duodenal ulcer bleeding near the minor duodenal papilla due to the possibility of PD.

Exclusive enteral nutrition is effective in pediatric Crohn disease but challenging as maintenance therapy. There is interest in food-based therapies such as the specific carbohydrate diet (SCD) but paucity of data on efficacy and effect on mucosal healing, an evolving target of IBD therapy. We conducted a retrospective review of the mucosal healing effect of the SCD in pediatric Crohn disease (CD). The endoscopic findings for children younger than 18 years with CD treated exclusively with the SCD or modified SCD (mSCD; SCD + addition of "illegal foods") were reviewed before and after the diet. Ileocolonoscopic examinations were scored according to the Simple Endoscopic Score for CD and findings on upper endoscopy were described. Seven subjects were identified, all on mSCD. The average age at starting the SCD was 11 ± 3.4 years and median duration of SCD/mSCD therapy was 26 months. All subjects reported no active symptoms before repeat endoscopic evaluation on mSCD, the majority had consistently normal C-reactive protein, albumin and hematocrit assessments, and mildly elevated fecal calprotectin (>50 μg/g, median 201, range 65-312) at any point within 3 months before the repeat endoscopy. One patient showed complete ileocolonic healing but persistent upper gastrointestinal tract ulceration. Complete macroscopic mucosal healing of both the ileocolon and upper gastrointestinal tract was not seen in any patient.

We present the case of a 52 years old man, with significant familial history, diagnosed with familial adenomatous polyposis-attenuated form, with no clinical and endoscopic surveillance until 2001 when he was admitted for an upper gastrointestinal haemorrhage episode. Upper gastrointestinal scopy revealed duodenal adenomatous polyps and gastric hyperplastic polyps. The patient underwent duodenopancreatectomy with total gastrectomy. The histopathological exam revealed duodenal G2 adenocarcinoma pT3N0, and gastric hyperplastic polyps with no signs of dysplasia. The surgical procedure was followed by chemotherapy. In 2002 the patient was admitted for rectal bleeding and colonoscopy showed 2 sigmoid polyps, appropriate for endoscopic removal and a poly-lobate polyp in the transverse colon. The patient underwent transverse colectomy (the histopathological exam--in situ carcinoma). March 2003--the patient underwent endoscopic removal for a rectal polyp (histopathological exam: moderate dysplasia). In 2005 was noted a pulmonary nodule, located in the postero-apical segment of upper left lobe, for which left superior lobe resection was performed (the histopathological exam: metastatic adenocarcinoma). In May 2006 was performed an exploratory laparotomy. Intraoperatively were noted: peritoneal carcinomatosis and multiple liver metastasis. The surgical procedure recommended in patients with attenuated form of familial adenomatous polyposis and suspect periampullary lesions is duodenopancreatectomy. The particularity of the case is the association of total gastrectomy for gastric hyperplastic polyps.

Measurements of tissue Zn in humans with upper gastrointestinal disease could provide information about underlying pathophysiology but these data have never been obtained. With recent endoscopic methods they obtained 2-6 mg pinch mucosal biopsies of epithelium and lamina propria from proximal (P), middle (M) and distal (D) areas of esophagus under direct vision through a flexible 1 cm endoscope in 35 subjects without gastrointestinal disease (N) and in 35 patients with the following endoscopically proven gastrointestinal pathology: 12 with esophagitis (E), 14 with duodenal ulcer disease (DU) and 9 with gastritis (G). Samples were dried, weighed, digested with HNO/sub 3/,more » dried, resuspended in 3% HNO/sub 3/ and Zn estimated by flame atomic absorption spectrophotometry. Esophageal Zn in N decreased progressively as biopsies extended from P to D (P, 108 +/- 29 ..mu..g/g dry weight, Mean +/- SEM; M, 158 +/- 23; D, 134 +/- 16) but this pattern was generally reversed in patients, with D consistently demonstrating Zn elevated 50-120% above normal. The greatest increase was in G in whom Zn in D was more than twice normal (DU, 290 +/- 76, p < 0.01). These are the first Zn levels obtained from esophagus in living human subjects and indicate (1) a specific pattern of Zn distribution in normal esophagus and (2) a significantly altered pattern in D in several diseases of the upper gastrointestinal tract.« less

Gastro-oesophageal reflux and dyspepsia are felt to be separate upper gastrointestinal (GI) conditions. We aimed to measure the degree of overlap between them, and assess whether endoscopic findings differed. Demographic, symptom, upper GI endoscopy and histology data were collected from consecutive adults in secondary care. Patients were categorised according to whether they reported gastro-oesophageal reflux alone, dyspepsia alone or both, and patient demographics and endoscopic findings were compared. Of 1167 patients, 97 (8.3%) had gastro-oesophageal reflux alone, 571 (48.9%) dyspepsia alone, and 499 (42.8%) overlap. Patients with overlap symptoms were more likely to smoke, compared with those with gastro-oesophageal reflux alone, or dyspepsia alone (p = .009), but there were no other differences. Patients with gastro-oesophageal reflux alone or overlap had a higher prevalence of erosive oesophagitis (18.6% and 15.4% respectively, p < .001), but this was still the commonest diagnosis among those with dyspepsia alone (7.2%). No significant differences were seen in prevalence of other endoscopic findings. Gastro-oesophageal reflux and dyspepsia symptoms commonly overlap. There were minimal differences in demographics or spectrum of underlying organic disease between various symptom groups, suggesting that restrictive classifications according to predominant symptom may not be clinically useful.

Acute esophageal necrosis (AEN), also called “black esophagus,” is a condition characterized by circumferential necrosis of the esophagus with universal distal involvement and variable proximal extension with clear demarcation at the gastroesophageal junction. It is an unusual cause of upper gastrointestinal bleeding and is recognized with distinct and striking mucosal findings on endoscopy. The patients are usually older and are critically ill with shared comorbidities, which include atherosclerotic cardiovascular disease, diabetes mellitus, hypertension, chronic renal insufficiency, and malnutrition. Alcoholism and substance abuse could be seen in younger patients. Patients usually have systemic hypotension along with upper abdominal pain in the background of clinical presentation of hematemesis and melena. The endoscopic findings confirm the diagnosis and biopsy is not always necessary unless clinically indicated in atypical presentations. Herein we present two cases with distinct clinical presentation and discuss the endoscopic findings along with a review of the published literature on the management of AEN. PMID:27642529

Complications associated with choledocholithiasis are uncommon during pregnancy. However, when it occurs, the morbidity and mortality related for the product and the mother increases, so a proper treatment is imperative in these patients. A 25-year-old pregnant woman on her second trimester. The current condition was started four days prior to the hospital admission with abdominal pain in the right upper quadrant with nausea and vomit.Twenty-four hours later jaundice and dark urine is observed. Physical examination shows scleral jaundice, right upper quadrant abdominal pain without peritoneal irritation. Uterus at umbilicus level without uterine activity. Uterus at umbilicus level without uterine activity. Laboratory tests showed elevated bilirubin and transaminases without leukocytosis; ultrasound reported live intrauterine unique product, with a heart rate of 128 beats per minute, gallbladder with multiple images inside that cast acoustic shadowing, and a 10 mm common bile duct dilated bile duct with dilatation of intrahepatic bile ducts. It was perform laparoscopic cholecystectomy with intraoperative cholangiography and placement of a transcystic jaguar guide for selective cannulation of the common bile duct. Intraoperative endoscopic retrograde cholangiopancreatography was performed with endoscopic stone extraction. The outcome was satisfactory with a hospital discharge at 48 hours. Current evidence has shown that the combined use of laparoscopy and therapeutic endoscopic cholangiography in one step is effective for the treatment of choledocholithiasis, decreasing the risk of complications associated with cannulation of the bile duct.

I-scan technology is the newly developed endoscopic tool that works in real time and utilizes a digital contrast method to enhance endoscopic image. We performed a feasibility study aimed to determine the diagnostic accuracy of i-scan technology for the evaluation of duodenal villous patterns, having histology as the reference standard. In this prospective, single center, open study, patients undergoing upper endoscopy for an histological evaluation of duodenal mucosa were enrolled. All patients underwent upper endoscopy using high resolution view in association with i-scan technology. During endoscopy, duodenal villous patterns were evaluated and classified as normal, partial villous atrophy, or marked villous atrophy. Results were then compared with histology. One hundred fifteen subjects were recruited in this study. The endoscopist was able to find marked villous atrophy of the duodenum in 12 subjects, partial villous atrophy in 25, and normal villi in the remaining 78 individuals. The i-scan system was demonstrated to have great accuracy (100 %) in the detection of marked villous atrophy patterns. I-scan technology showed quite lower accuracy in determining partial villous atrophy or normal villous patterns (respectively, 90 % for both items). Image-enhancing endoscopic technology allows a clear visualization of villous patterns in the duodenum. By switching from the standard to the i-scan view, it is possible to optimize the accuracy of endoscopy in recognizing villous alteration in subjects undergoing endoscopic evaluation.

We report an integrated Raman spectroscopy and trimodal (white-light reflectance, autofluorescence, and narrow-band) imaging techniques for real-time in vivo tissue Raman measurements at endoscopy. A special 1.8 mm endoscopic Raman probe with filtering modules is developed, permitting effective elimination of interference of fluorescence background and silica Raman in fibers while maximizing tissue Raman collections. We demonstrate that high-quality in vivo Raman spectra of upper gastrointestinal tract can be acquired within 1 s or subseconds under the guidance of wide-field endoscopic imaging modalities, greatly facilitating the adoption of Raman spectroscopy into clinical research and practice during routine endoscopic inspections.

The discrepancy between spatial orientations of an endoscopic image and a physician's working environment can make it difficult to interpret endoscopic images. In this study, we developed and evaluated a device that corrects the endoscopic image orientation using an accelerometer and gyrosensor. The acceleration of gravity and angular velocity were retrieved from the accelerometer and gyrosensor attached to the handle of the endoscope. The rotational angle of the endoscope handle was calculated using a Kalman filter with transmission delay compensation. Technical evaluation of the orientation correction system was performed using a camera by comparing the optical rotational angle from the captured image with the rotational angle calculated from the sensor outputs. For the clinical utility test, fifteen anesthesiology residents performed a video endoscopic examination of an airway model with and without using the orientation correction system. The participants reported numbers written on papers placed at the left main, right main, and right upper bronchi of the airway model. The correctness and the total time it took participants to report the numbers were recorded. During the technical evaluation, errors in the calculated rotational angle were less than 5 degrees. In the clinical utility test, there was a significant time reduction when using the orientation correction system compared with not using the system (median, 52 vs. 76 seconds; P = .012). In this study, we developed a real-time endoscopic image orientation correction system, which significantly improved physician performance during a video endoscopic exam.
Endoscopic Treatment of Upper Tract Urothelial Carcinoma.
Verges, Daniel P; Lallas, Costas D; Hubosky, Scott G; Bagley, Demetrius H
2017-04-01
This study aims to make the reader be aware of recent trends regarding the endoscopic management of upper tract urothelial carcinoma (UTUC) via review of the urologic literature over the past 5 years. Given the rare incidence of this disease, and the lack of level 1 evidence, systematic reviews and meta-analyses were also evaluated. Studies of importance are also considered and outlined in the annotated reference section. The PubMed database was queried using the following medical subject headings (MeSH terms): "carcinoma, transitional cell," "ureter," "ureteral neoplasms," "kidney pelvis," "endoscopy," "laser therapy," "ureteroscopy," "urologic surgical procedures," and "ureteroscopes." MeSH terms were linked together in varying combinations and limited to human studies in English. Given the relatively rare nature of upper tract urothelial carcinoma (UTUC), level 1 evidence regarding the efficacy of endoscopic treatment does not exist, even after 30+ years of experience. Rather, the literature available mostly is in the form of single institutional retrospective series consisting of relatively small numbers of patients with short to intermediate follow-up. Only within the last 3 years have published series with larger numbers of patients and mean follow-up over 5 years been made available. Even with these more robust experiences, comparisons among series are difficult given variable treatment and follow-up approaches. Most endoscopically managed UTUC will locally recur, especially with longer follow-up. Renal preservation rate is high, however, approaching 80% with follow-up well over 3 years. Patients with high-grade disease often fare poorly regardless of treatment modality. As such, endoscopic management for high-grade urothelial carcinoma should only be used in exceptional circumstances (i.e., in those patients medically unfit for NU or those with solitary kidneys wishing to avoid the morbidity of dialysis). No level 1 evidence exists for the routine use of intraluminal adjuvant therapy for UTUC (i.e., BCG and Mitomycin C) and multiple retrospective observational series claim there is no overt benefit. The recent formation of multiple international groups with interest in UTUC may eventually lead to the production of level 1 studies regarding optimal treatment; however, uniformity in treatment approach will likely still offer challenges.

We developed a novel method of endoscopic subserosal dissection (ESSD) for removal of subepithelial tumors (SETs) originating from the muscularis propria (MP) layer in the upper gastrointestinal (GI) tract. The aim of this study was to evaluate the efficacy, safety, and clinical outcome of this method. Eleven patients with upper GI SETs originating from the MP layer were treated by ESSD between October 2016 and March 2017. ESSD technique consists of six major procedures: (1) incising the mucosal and submucosal layer around the lesion and exposing MP layer; (2) continuous injection was performed while the injection needle slowly moved from the MP layer toward the subserosal layer; (3) incising MP layer; (4) subserosal injection was performed to further separate the serosa from the MP layer; (5) the mucosa, submucosa, and MP layer including SET were carefully dissected en bloc; and (6) closure of the gastric-wall defect with endoscopic techniques. Primary outcome including clinical procedural success and procedure-related adverse events were documented. ESSD was successfully performed in 11 patients. The complete resection rate was 100%, and the mean operation time was 51 (range 22-76) min. The mean resected lesion size was 27 (range 15-40) mm. Pathological diagnosis of these lesions included gastrointestinal stromal tumors (8/11), heterotopic pancreas (1/11), hamartoma (1/11), and leiomyoma (1/11). The small perforations occurred in two patients (4 × 4 and 5 × 5 mm, respectively) during the operation. All perforations and defects were closed successfully by endoscopic techniques. No GI bleeding, peritonitis, abdominal abscess, and other adverse events were observed. No lesion residual or recurrence was found during the follow-up period (mean 18 weeks; range 10-29 weeks). ESSD seems to be an efficacious, safe, and minimally invasive treatment for patients with upper GI SETs originating from the MP layer, making it possible to resect deep lesions, provide precise pathological diagnosis, and maintain the integrity of serosa.

In Korea, gastric cancer screening, either esophagogastroduodenoscopy or upper gastrointestinal series (UGIS), is performed biennially for adults aged 40 years or older. Screening endoscopy has been shown to be associated with localized cancer detection and better than UGIS. However, the diagnostic sensitivity of detecting cancer is not satisfactory. The National Endoscopy Quality Improvement (QI) program was initiated in 2009 to enhance the quality of medical institutions and improve the effectiveness of the National Cancer Screening Program (NCSP). The Korean Society of Gastrointestinal Endoscopy developed quality standards through a broad systematic review of other endoscopic quality guidelines and discussions with experts. The standards comprise five domains: qualifications of endoscopists, endoscopic unit facilities and equipment, endoscopic procedure, endoscopy outcomes, and endoscopic reprocessing. After 5 years of the QI program, feedback surveys showed that the perception of QI and endoscopic practice improved substantially in all domains of quality, but the quality standards need to be revised. How to avoid missing cancer in endoscopic procedures in daily practice was reviewed, which can be applied to the mass screening endoscopy. To improve the quality and effectiveness of NCSP, key performance indicators, acceptable quality standards, regular audit, and appropriate reimbursement are necessary.

Background and study aims: Congenital duodenal web (CDW) is an uncommon cause of duodenal obstruction and endoscopic balloon dilatation has been reported in just eight pediatric cases to date. Here we are reporting three cases of CDW managed successfully with balloon dilatation. Cases and methods: In 2014 we diagnosed three cases of CDW on the basis of typical radiological and endoscopic findings. Endoscopic balloon dilatation was done under conscious sedation with a through-the-scope controlled radial expansion (CRE) balloon. Results: All three children presented late (median age 8 [range 2 – 9] years) with bilious vomiting, upper abdominal distension, and failure to thrive. One of them had associated Down syndrome and another had horseshoe kidney. In all cases, CDW was observed in the second part of the duodenum beyond the ampulla, causing partial duodenal obstruction. After repeated endoscopic dilatation (2 – 4 sessions), all three patients became asymptomatic. None of the patients experienced complications after balloon dilatation. Conclusions: Duodenal diaphragm should be suspected in patients with abdominal distension with bilious vomiting, even in relatively older children. Endoscopic balloon dilatation is a simple and effective method of treating this condition. PMID:27004237

With increased use of percutaneous endoscopic gastrostomy, it became clear that neurologically impaired patients might benefit from its use. From August 1996 to July 1997, we performed 19 percutaneous endoscopic gastrostomies in patients with neurological sequelae, who were incapable to maintain their nutritional status by oral ingestion or had repeated episodes of aspiration. Sixteen patients were followed prospectively, from 30 days to 11 months (median: 6.4 months). Average weight (38.2 kg to 44.8 kg), BMI (14.8 kg/m2 to 17.8 kg/m2), weight/height ratio (23.5 kg/cm to 28 kg/cm), mid-upper arm circumference (19.4 cm to 21.6 cm) and triceps skinfold thickness (10.3 mm to 12.6 mm) were significantly increased (P < 0.01). Before percutaneous endoscopic gastrostomy, there were 10 (10/16, 62.5%) patients with grade III thinness. In this group, 3/10 patients (30%) showed improvement to grade I (two individuals) and II (one patient). All but five patients (68.75%) were below the fifth percentile of normal distribution for mid-upper arm circumference. One patient (6.2%) showed improvement of her status (between 25th and 50th percentiles). Four patients (25%) started the follow-up below the fifth percentile for normal distribution of triceps skinfold thickness, and showed no improvement. There were no early complications secondary the procedure. Late complications included granulation tissue on ostomy site (18.8%) and ostomy infection (6.2%). Statistical analysis showed significant improvement of anthropometric data. Percutaneous endoscopic gastrostomy is a simple, highly successful and safe procedure, when performed in neurologically impaired patients. It is efficient as a long-term enteral feeding method.

Pediatric small-bowel (SB) Crohn disease (CD) may be missed if the terminal ileum (TI) appears normal at endoscopy and SB imaging is not performed. We sought to estimate the prevalence and clinical characteristics of pediatric patients with CD and endoscopic skipping of the TI-that is, pediatric patients with active SB or upper gut inflammation and an endoscopically normal TI. This retrospective study included pediatric patients with CD who underwent both CT enterography (CTE) or MR enterography (MRE) and ileocolonoscopy within a 30-day period between July 2004 and April 2014. The physician global assessment was used as the reference standard for SB CD activity. Radiologists reviewed the CTE and MRE studies for inflammatory parameters; severity, length, and multifocality of SB inflammation; and the presence of penetrating complications. Of 170 patients who underwent ileal intubation, the TI was macroscopically normal or showed nonspecific inflammation in 73 patients (43%). Nearly half (36/73, 49%) of the patients with normal or nonspecific findings at ileocolonoscopy had radiologically active disease with a median length of SB involvement of 20 cm (range, 1 to > 100 cm). Seventeen (47%) of these patients had multifocal SB involvement and five (14%) had penetrating complications. Overall, endoscopic TI skipping was present in 43 (59%) patients with normal or nonspecific ileocolonoscopic findings: 20 with histologic inflammation (17 with positive imaging findings), 14 with inflammation at imaging only, and nine with proximal disease (upper gut, jejunum, or proximal ileum). There were no significant differences in the clinical parameters of the patients with and those without endoscopic TI skipping. Ileocolonoscopy may miss SB CD in pediatric patients that is due to isolated histologic, intramural, or proximal inflammation. Enterography is complementary to ileocolonoscopy in the evaluation of pediatric CD.

Although duodenal lymphangiectasia in individuals without clinical evidence of malabsorption has been reported, the prevalence and clinical significance in this situation are not yet known. The aim of this study was to evaluate the prevalence and clinical significance of incidentally found duodenal lymphangiectasia. A retrospective review of medical records was undertaken for consecutive patients who had undergone diagnostic upper endoscopy between January 2005 and June 2006. A prospective study was then performed in consecutive individuals undergoing routine upper endoscopy for health examination between July 2006 to October 2006. Endoscopic features of duodenal lymphangiectasia were classified into three types: (1) multiple scattered pinpoint white spots; (2) diffuse prominent villi with whitish-discolored tips; and (3) focal small whitish macule or nodule. The histologic grade of duodenal lymphangiectasia was classified according to the depth and severity of lymphatic duct dilatations. Prevalence and clinical data of incidentally found duodenal lymphangiectasia were evaluated in the retrospective and prospective studies. Among 1866 retrospective cases, duodenal lymphangiectasia was endoscopically suspected in 59 cases (3.2%), and histologically confirmed in 35 cases (1.9%). No clinical evidence of malabsorption was noted in the duodenal lymphangiectasia cases. The "scattered pinpoint white spots" type was the most frequently found endoscopic feature (40.0%). Duodenal lymphangiectasia was persistent in seven of 10 individuals who underwent repeat endoscopy after a median of 12 months. Among 134 prospective cases, duodenal lymphangiectasia was histologically confirmed in 12 cases (8.9%). There was no significant clinical difference between groups with and without duodenal lymphangiectasia. Lymphatic duct dilatation was histologically more severe in the "focal small whitish macule or nodule" type than in the other types. Duodenal lymphangiectasia without clinical evidence of malabsorption is not extremely rare among cases undergoing routine upper gastrointestinal endoscopy.

Acute gastrointestinal bleeding is a potentially life-threatening condition that requires rapid assessment and dynamic management. Several scoring systems are used to predict mortality and rebleeding in such cases. The aim of the present study was to compare three scoring systems for predicting short-term mortality, rebleeding, duration of hospitalization and the need for blood transfusion in elderly patients with upper gastrointestinal bleeding. The present study included 335 elderly patients with upper gastrointestinal bleeding. Pre- and post-endoscopic Rockall, Glasgow-Blatchford and AIMS65 scores were calculated. The ability of these scores to predict rebleeding, mortality, duration of hospitalization and the need for blood transfusion was determined. Pre- (4.5) and post-endoscopic (7.5) Rockall scores were superior to the Glasgow-Blatchford (12.5) score for predicting mortality (P = 0.006 and P = 0.015). Likewise, pre- (4.5) and post-endoscopic Rockall scores were superior to the respective Glasgow-Blatchford scores for predicting rebleeding (P = 0.013 and P = 0.03). There was an association between duration of hospitalization and mortality; as the duration of hospitalization increased the mortality rate increased. In all, 94% of patients hospitalized for a mean of 5 days were alive versus 56.1% of those hospitalized for 20 days, and 20.2% of those hospitalized for 40 days. In elderly patients with upper gastrointestinal bleeding, the Rockall score is clinically more useful for predicting mortality and rebleeding than the Glasgow-Blatchford and AIMS65 scores; however, for predicting duration of hospitalization and the need for blood transfusion, the Glasgow-Blatchford score is superior to the Rockall and AIMS65 scores.

With the aim of analysing the frequency of gastrointestinal (GI) metastases identified by endoscopic procedures, a survey was conducted by questionnaire, which was completed by 34 of 127 medical departments. Peritoneal carcinosis and direct tumor extension were disregarded. One GI metastasis (duodenum) was verified among 3477 upper GI tract endoscopies. Primary site was cutaneous melanoma. In another case metastatic origin is discussed (esophagus). Considering the average frequency of 102 upper GI tract endoscopies performed by the collaborating centers, one case of gastroduodenal metastasis could be expected every 17 (34) months in these institutions. 1634 examinations of the colon and rectum did not reveal any metastatic tumor growth. A longterm study is planned to provide further statistically reliable prevalence data.

Acute upper gastrointestinal bleedings from ulcers or esophago-gastric varices are life threatening medical conditions which require immediate endoscopic therapy. Despite successful endoscopic hemostasis, there is a significant risk of rebleeding often requiring close surveillance of these patients in the intensive care unit (ICU). Any time delay to recognize bleeding may lead to a high blood loss and increases the risk of death. A novel telemetric real-time bleeding sensor can help indicate blood in the stomach: the sensor is swallowed to detect active bleeding or is anchored endoscopically on the gastrointestinal wall close to the potential bleeding source. By telemetric communication with an extra-corporeal receiver, information about the bleeding status is displayed. In this study the novel sensor, which measures characteristic optical properties of blood, has been evaluated in an ex-vivo setting to assess its clinical applicability and usability. Human venous blood of different concentrations, various fluids, and liquid food were tested. The LED-based sensor was able to reliably distinguish between concentrated blood and other liquids, especially red-colored fluids. In addition, the spectrometric quality of the small sensor (size: 6.5mm in diameter, 25.5mm in length) was comparable to a much larger and technically more complex laboratory spectrophotometer. The experimental data confirm the capability of a miniaturized sensor to identify concentrated blood, which could help in the very near future the detection of upper gastrointestinal bleeding and to survey high-risk patients for rebleeding.

The translamina terminalis corridor was used in the transcranial anterior route to treat third ventricular craniopharyngioma (TVC), which presents a challenge to neurosurgeons. The endoscopic endonasal approach (EEA) has recently been used to treat craniopharyngiomas. However, there are few reports of the EEA being used to treat TVC. The authors' novel surgical approach of treating selected TVC by the endoscopic endonasal route via the suprachiasmatic translamina terminalis (STLT) corridor is described. In this single-center study, the EEA via the STLT corridor was used to resect TVC with great upper and anterior extension causing bulged lamina terminalis, and TVC with a residual upper compartment, after routine infrachiasmatic transmetastalk corridor resection. The STLT corridor was used in 3 patients. Gross-total resection was achieved in all cases. One patient achieved visual improvement, and the other 2 patients showed partial visual improvement. Leakage of CSF occurred in 1 patient. Postoperative hormone replacement therapy was required in all patients. The STLT corridor is a complementary minimally invasive corridor used in the EEA for treating selected TVC. The STLT alone or combined with infrachiasmatic transmetastalk corridors should be selected depending on the size of suprachiasmatic and infrachiasmatic space.

This case report is intended to inform clinicians, endoscopists, policy makers and industry of our experience in the management of a rare case of mobile phone ingestion. A 29-year-old prisoner presented to the Emergency Department with vomiting, ten hours after he claimed to have swallowed a mobile phone. Clinical examination was unremarkable. Both initial and repeat abdominal radiographs eight hours later confirmed that the foreign body remained in situ in the stomach and had not progressed along the gastrointestinal tract. Based on these findings, upper endoscopy was performed under general anaesthesia. The object could not be aligned correctly to accommodate endoscopic removal using current retrieval devices. Following unsuccessful endoscopy, an upper midline laparotomy was performed and the phone was delivered through an anterior gastrotomy, away from the pylorus. The patient made an uneventful recovery and underwent psychological counselling prior to discharge. In this case report, the use of endoscopy in the management when a conservative approach fails is questioned. Can the current endoscopic retrieval devices be improved to limit the need for surgical interventions in future cases? An ingested mobile phone in the stomach may not be amenable for removal using the current endoscopic retrieval devices. Improvements in overtubes or additional modifications of existing retrieval devices to ensure adequate alignment for removal without injuring the oesophagus are needed. Copyright © 2016 The Authors.

Immediate Partial Breast Reconstruction with Endoscopic Latissimus Dorsi Muscle Flap Harvest
Yang, Chae Eun; Roh, Tai Suk; Yun, In Sik; Lew, Dae Hyun
2014-01-01
Background Currently, breast conservation therapy is commonly performed for the treatment of early breast cancer. Depending on the volume excised, patients may require volume replacement, even in cases of partial mastectomy. The use of the latissimus dorsi muscle is the standard method, but this procedure leaves an unfavorable scar on the donor site. We used an endoscope for latissimus dorsi harvesting to minimize the incision, thus reducing postoperative scars. Methods Ten patients who underwent partial mastectomy and immediate partial breast reconstruction with endoscopic latissimus dorsi muscle flap harvest were reviewed retrospectively. The total operation time, hospital stay, and complications were reviewed. Postoperative scarring, overall shape of the reconstructed breast, and donor site deformity were assessed using a 10-point scale. Results In the mean follow-up of 11 weeks, no tumor recurrence was reported. The mean operation time was 294.5 (±38.2) minutes. The postoperative hospital stay was 11.4 days. Donor site seroma was reported in four cases and managed by office aspiration and compressive dressing. Postoperative scarring, donor site deformity, and the overall shape of the neobreast were acceptable, scoring above 7. Conclusions Replacement of 20% to 40% of breast volume in the upper and the lower outer quadrants with a latissimus dorsi muscle flap by using endoscopic harvesting is a good alternative reconstruction technique after partial mastectomy. Short incision benefits from a very acceptable postoperative scar, less pain, and early upper extremity movement. PMID:25276643

Background There exists a complex interplay between asthma and gastroesophageal reflux disease. Both these diseases are known to aggravate each other and amelioration of one is necessary for the control of the other. There is a paucity of studies in Indian population on this subject. Aim To evaluate the clinical features and the endoscopic findings of the upper gastrointestinal tract in patients with bronchial asthma. Materials and Methods Study was conducted at KMC group of hospitals, Mangalore in the Department of chest medicine in association with Department of gastroenterology. Subjects included 50 cases of bronchial asthma and controls were 58 non asthmatic patients with allergic rhinitis and chronic urticaria. All patients were queried about presence or absence of symptoms of upper gastro intestinal tract disorders by gastro oesophageal reflux disease (GERD) questionnaire and all the included patients underwent upper gastro intestinal endoscopy. Results The study showed that symptoms of gastroesophageal reflux were significantly more in asthmatics (52%) as compared to the controls (28%). The common presenting features of gastroesophageal reflux in asthmatics were heartburn (40%) retrosternal pain (24%), nocturnal cough (18%), dyspepsia (16%) and regurgitation (14%) and the above symptoms were significantly more common in asthmatics as compared to controls. Gastroesophageal reflux disease was found to be significantly more common in the asthmatics (58%) as compared to the control group where it was present in 32.75% of the subjects. Clinical or endoscopic evidence of any upper gastrointestinal disorder was found in 68% of the asthmatics as compared to 37.93% of the controls. This difference was found to be statistically significant. Conclusion The study showed that gastroesophageal reflux disease was significantly more in asthmatics as compared to the controls. Upper gastrointestinal symptoms were more common in asthmatics as against controls. Clinical or endoscopic evidence of upper gastrointestinal disorder and gastroesophageal reflux disease was found in significantly higher proportion of the asthmatics as compared to the controls. Clinically silent gastroesophageal reflux disease was however seen in both control and asthmatic groups equally with a lower prevalence. PMID:26557556

Background Cholesterol granulomas arising at the petrous apex can be treated via traditional open surgical, endoscopic, and endoscopic-assisted approaches. Endoscopic approaches require access to the sphenoid sinus, which is technically challenging in patients with conchal sphenoidal anatomy. Clinical Presentation A 55-year-old woman presented with intermittent headaches and tinnitus. Formal audiometry demonstrated moderately severe bilateral hearing loss. CT of the temporal bones and sella revealed a well-demarcated expansile lytic mass. MRI of the face, orbit, and neck showed a right petrous apex mass measuring 22 × 18 × 19 mm that was hyperintense on T1- and T2-weighted images without enhancement, consistent with a cholesterol granuloma. The patient had a conchal sphenoidal anatomy. Operative Technique Herein, we present an illustrative case of a low-lying petroclival cholesterol granuloma in a patient with conchal sphenoidal anatomy to describe an alternative high nasopharyngeal corridor for endoscopic transnasal transclival access. Postoperative Course Postoperatively, the patient's symptoms recovered and no complications occurred. Follow-up imaging demonstrated a patent drainage tract without evidence of recurrence. Conclusion In patients with a conchal sphenoid sinus, endoscopic transnasal transclival access can be gained using a high nasopharyngeal approach. This corridor facilitates safe access to these lesions and others in this location.

The importance of minimally invasive surgery in urology has constantly increased in the last 20 years. Endoscopic resection of prostate and bladder tumors is actually a gold standard with many advantages for patients. To analyze the problems related to the ergonomic conditions faced by urologist during video endoscopic surgery by review of the recent literature. All evidence-based experimental ergonomic studies conducted in the fields of urology endoscopic surgery and applied ergonomics for other professions working with a display were identified by PubMed searches. Data from ergonomic studies were evaluated in terms of efficiency as well as comfort and safety aspects. Constraint postures for urologists are described and ergonomic requirements for optimal positions are discussed. The ergonomics of urological endoscopic surgery place urologists at risk for potential injury. The amount of neck flexion or extension, the amount of shoulder girdle adduction or abduction used, and stability of the upper extremities during surgery; which are maintained in a prolonged static posture; are the main risk factors. All these constraints may lead to muscle and joint fatigue, pain, and eventual musculoskeletal injury. Moreover, these issues may impact surgical accuracy. Urologist posture, operating period, training are important ergonomic factor during video surgery to prevent musculoskeletal disorders.

Dieulafoy's lesion is one of an unusual cause of upper gastrointestinal bleeding (U GIB). Endoscopic intervention has always been a preferred non-surgical method in treating UGIB including bleeding from Dieulafoy's lesion. Owing to recent advances in angiography, arterial embolization has become a popular alternative in non- variceal UGIB especially in cases with failed endoscopic treatment. However, managing bleeding Dieulafoy's with selective arterial embolization as the first line of treatment has not been exclusively practiced. We hereby, report a case of bleeding Dieulafoy lesion which had been primarily treated with arterial embolization.

It is not clear whether H 2 -receptor antagonists (H2RAs) reduce the risk of gastrointestinal (GI) bleeding in aspirin users at high risk. We performed a double-blind randomized trial to compare the effects of a proton pump inhibitor (PPI) vs a H2RA antagonist in preventing recurrent upper GI bleeding and ulcers in high-risk aspirin users. We studied 270 users of low-dose aspirin (≤325 mg/day) with a history of endoscopically confirmed ulcer bleeding at 8 sites in Hong Kong and Japan. After healing of ulcers, subjects with negative results from tests for Helicobacter pylori resumed aspirin (80 mg) daily and were assigned randomly to groups given a once-daily PPI (rabeprazole, 20 mg; n = 138) or H2RA (famotidine, 40 mg; n = 132) for up to 12 months. Subjects were evaluated every 2 months; endoscopy was repeated if they developed symptoms of upper GI bleeding or had a reduction in hemoglobin level greater than 2 g/dL and after 12 months of follow-up evaluation. The adequacy of upper GI protection was assessed by end points of recurrent upper GI bleeding and a composite of recurrent upper GI bleeding or recurrent endoscopic ulcers at month 12. During the 12-month study period, upper GI bleeding recurred in 1 patient receiving rabeprazole (0.7%; 95% confidence interval [CI], 0.1%-5.1%) and in 4 patients receiving famotidine (3.1%; 95% CI, 1.2%-8.1%) (P = .16). The composite end point of recurrent bleeding or endoscopic ulcers at month 12 was reached by 9 patients receiving rabeprazole (7.9%; 95% CI, 4.2%-14.7%) and 13 patients receiving famotidine (12.4%; 95% CI, 7.4%-20.4%) (P = .26). In a randomized controlled trial of users of low-dose aspirin at risk for recurrent GI bleeding, a slightly lower proportion of patients receiving a PPI along with aspirin developed recurrent bleeding or ulcer than of patients receiving an H2RA with the aspirin, although this difference was not statistically significant.

Cerebral Arterial Gas Embolism During Upper Endoscopy.
Eoh, Eun J; Derrick, Bruce; Moon, Richard
2015-09-15
Arterial gas embolism can be caused by direct entry of gas into systemic arteries or indirectly by venous-to-arterial shunting. Although arterial gas embolism is rare, most documented cases are iatrogenic, resulting from the entry of gas during procedures that involve direct vascular cannulation or intracavitary air insufflation. Of the 18 identified case reports of air embolism during endoscopy, 11 cases describe findings of cerebral arterial gas embolism during upper endoscopy. Only 1 of these occurred during endoscopic balloon dilation of an esophageal stricture. We report a rare case of cerebral arterial gas embolism in a 64-year-old woman, which occurred during endoscopic dilation of an esophageal stricture and was subsequently treated with hyperbaric oxygen therapy. In this case report, we explore the possible etiologies, clinical workup, and therapeutic management of cerebral artery gas embolisms. Hyperbaric oxygen therapy is the treatment of choice for cerebral arterial gas embolism, with earlier treatments resulting in better outcomes.

Heterotopic gastric mucosa patches are congenital gastrointestinal abnormalities and have been reported to occur anywhere along the gastrointestinal tract from mouth to anus. Complications of heterotopic gastric mucosa include dysphagia, upper gastrointestinal bleeding, upper esophageal ring stricture, adenocarcinoma and fistula formation. In this case report we describe the diagnosis and treatment of the first case of esophago-bronchial fistula due to heterotopic gastric mucosa in mid esophagus. A 40-year old former professional soccer player was referred to our department for treatment of an esophago-bronchial fistula. Microscopic examination of the biopsies taken from the esophageal fistula revealed the presence of gastric heterotopic mucosa. We decided to do a non-surgical therapeutic endoscopic procedure. A sclerotherapy catheter was inserted through which 1 mL of ready to use synthetic surgical glue was applied in the fistula and it closed the fistula opening with excellent results.

To evaluate the severity of airway pathologies, quantitative dimensioning of airways is of utmost importance. Endoscopic vision gives a projective image and thus no true scaling information can be directly deduced from it. In this article, an approach based on an interferometric setup, a low-coherence laser source and a standard rigid endoscope is presented, and applied to hollow samples measurements. More generally, the use of the low-coherence interferometric setup detailed here could be extended to any other endoscopy-related field of interest, e.g., gastroscopy, arthroscopy and other medical or industrial applications where tri-dimensional topology is required. The setup design with a multiple fibers illumination system is presented. Demonstration of the method ability to operate on biological samples is assessed through measurements on ex vivo pig bronchi.

There have been no reports of primary leiomyosarcoma of the stomach treated by endoscopic submucosal dissection (ESD). We report an extremely rare case of gastric leiomyosarcoma that was successfully treated by ESD. An asymptomatic 74-year-old female underwent esophagogastroduodenoscopy for screening in December 2013. A centrally depressed submucosal tumor 10 mm in diameter was detected at the posterior wall of the upper gastric body. Follow-up esophagogastroduodenoscopy conducted 5 months later showed that the tumor diameter had increased to 15 mm. Endoscopic ultrasound revealed a hypoechoic mass located in the second to the middle of the third layer. Endoscopic ultrasound-guided fine-needle aspiration demonstrated a myogenic tumor. The tumor was completely resected by ESD without complications. Immunohistopathological diagnosis of the resected specimen was gastric leiomyosarcoma derived from the muscularis mucosae, with negative lateral and vertical margins. No local recurrence or metastasis has been detected at 36 months after ESD. This is the first report of gastric leiomyosarcoma treated by ESD in the English language literature.

Type I gastric carcinoid tumors result from hypergastrinemia in 1%-7% of patients with pernicious anemia. We diagnosed pernicious anemia in a 48-year-old female patient with complaint of fatigue for three months. She had no gastrointestinal symptoms. Endoscopic examination ot the upper gastrointestinal tract revealed atrophic gastritis and a polypoid lesion in the corpus of 3-4 mm in size. Endoscopic polypectomy was performed. Histopathological examination of the specimen revealed positive chromogranin A and synaptophysin stainings compatible with the diagnosis of a carcinoid tumor. Serum gastrin level was increased, urinary 5-hydroxyindoleacetic acid was within the normal range. There was no other symptom, sign, or laboratory finding of a carcinoid syndrome in the patient. No metastasis was found with indium-111 octreotide scan, computed tomographies of abdomen and thorax. Type I gastric carcinoid tumors are only rarely solitary and patients with tumors < 1 cm in size may benefit from endoscopic polypectomy. PMID:16830392

Helicobacter pylori is a known contributor to ulcerogenesis and nonvariceal acute upper gastrointestinal hemorrhage. Its incidence in operatively managed patients with upper gastrointestinal hemorrhage is ill defined. Patients undergoing surgery for upper gastrointestinal hemorrhage secondary to gastroduodenal ulceration between 1993 and 1998 at the University of Tennessee were retrospectively reviewed. Factors examined included age, nonsteroidal drug use, endoscopic intervention, urgency of operation, and H. pylori status confirmed by histologic examination. Forty-two patients had surgery with three excluded because of a lack of histologic evaluation. The site of bleeding was gastric in 23 and duodenal in 14. H. pylori infection was present in nine (39.1%) gastric and 11 (68.7%) duodenal ulcers. The incidence of H. pylori infection was reduced in those over 60 years of age (28.6%). Endoscopy was performed in all patients, but only two had biopsies for assessment of H. pylori. Operative morbidity was 17.9% and mortality was 5.1%. No patient had rebleeding following surgery. The incidence of H. pylori in this population is less than that reported in uncomplicated ulcer disease. Those older than 60 tended to be H. pylori negative. Endoscopic assessment for H. pylori was infrequent. Traditional indications for surgical intervention in ulcer hemorrhage should not be altered based on H. pylori status.

To aid in diagnosis and treatment of upper airway obstructive disorders (UAOD), we propose anatomic Optical Coherence Tomography (aOCT) for endoscopic imaging of the upper airway lumen with high speed and resolution. aOCT and CT scans are performed sequentially on in vivo swine to compare dynamic airway imaging data. The aOCT system is capable of capturing the dynamic deformation of the airway during respiration. This may lead to methods for airway elastography and aid in our understanding of dynamic collapse in UAOD.

Background and aim: This technical review is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the utilization of advanced endoscopic imaging in gastrointestinal (GI) endoscopy. Methods: This technical review is based on a systematic literature search to evaluate the evidence supporting the use of advanced endoscopic imaging throughout the GI tract. Technologies considered include narrowed-spectrum endoscopy (narrow band imaging [NBI]; flexible spectral imaging color enhancement [FICE]; i-Scan digital contrast [I-SCAN]), autofluorescence imaging (AFI), and confocal laser endomicroscopy (CLE). The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was adopted to define the strength of recommendation and the quality of evidence. Main recommendations: 1. We suggest advanced endoscopic imaging technologies improve mucosal visualization and enhance fine structural and microvascular detail. Expert endoscopic diagnosis may be improved by advanced imaging, but as yet in community-based practice no technology has been shown consistently to be diagnostically superior to current practice with high definition white light. (Low quality evidence.) 2. We recommend the use of validated classification systems to support the use of optical diagnosis with advanced endoscopic imaging in the upper and lower GI tracts (strong recommendation, moderate quality evidence). 3. We suggest that training improves performance in the use of advanced endoscopic imaging techniques and that it is a prerequisite for use in clinical practice. A learning curve exists and training alone does not guarantee sustained high performances in clinical practice. (Weak recommendation, low quality evidence.) Conclusion: Advanced endoscopic imaging can improve mucosal visualization and endoscopic diagnosis; however it requires training and the use of validated classification systems. © Georg Thieme Verlag KG Stuttgart · New York.

Wireless capsule endoscopy (WCE) is an increasingly used procedure for visualization of the small intestine. One challenge in pediatric WCE is the placement of the capsule in a population unable to swallow it for a variety of reasons. Here we present a novel use of the real-time (RT) viewer in the endoscopic deployment of the capsule endoscope. We performed a retrospective chart review on all WCE completed at the Children's Memorial Hospital from February 2010 to May 2011. Following a diagnostic upper endoscopy, the RT viewer was attached to the capsule recorder and image was noted before insertion. The endoscope and AdvanCE capsule delivery device were slowly advanced into duodenum while maintaining visualization on the RT viewer. A total of 17 patients who underwent a WCE with endoscopic placement were identified. They ranged in ages from 2 to 19 years. Thirteen patients required endoscopic placement because of the inability to swallow the capsule, whereas 4 were placed during a scheduled procedure to take advantage of sedation and airway protection. All of the 17 patients had successful deployment of the capsule into the duodenal lumen. In each case, the endoscopist was able to confirm capsule location in duodenum during scope withdrawal. There was no evidence of iatrogenic trauma or bleeding in any patient. There were 5 incomplete studies, a completion rate consistent with that described in the literature. The use of the RT viewer for endoscopic deployment of WCE is an effective technique to improve visualization of capsule placement in the pediatric population.

Endoscopic Mucosal Resection (EMR) is now widely practised by western endoscopists to treat large sessile colonic polyps or laterally spreading tumours. Despite its widespread application, the technique of colonic EMR is not standardised. A lesion specific endoscopic treatment approach is also lacking. For lesions larger than 25mm, EMR is limited by its inability to achieve en-bloc resection. En-bloc resection has many theoretical advantages including more accurate histological assessment, reduced recurrence and potentially curative treatment for low risk submucosal invasive neoplasia particularly in patients with significant co-morbidity. Hence, Japanese endoscopists, having pioneered endoscopic submucosal dissection (ESD) in the upper gastrointestinal tract for the en-bloc resection of superficial neoplasia, now advocate the use of ESD for laterally spreading tumours of the colon greater than 25-30mm. This treatment strategy is not widely accepted or practised in the west and has its own inherent problems. The absence of suitable gastric lesions on which to develop ESD skills is also another significant barrier to the development of colonic ESD. It is also possible that modification and refinement in EMR technique may increase the size limit for colonic EMR.

Here, we report the first successful endoscopic resection of an exophytic gastrointestinal stromal tumor (GIST) using a novel perforation-free suction excavation technique. A 49-year-old woman presented for further management of a gastric subepithelial tumor on the lesser curvature of the lower body, originally detected via routine upper gastrointestinal endoscopy. Abdominal computed tomography and endoscopic ultrasound showed a 4-cm extraluminally protruding mass originating from the muscularis propria layer. The patient firmly refused surgical resection owing to potential cardiac problems, and informed consent was obtained for endoscopic removal. Careful dissection and suction of the tumor was repeated until successful extraction was achieved without serosal injury. We named this procedure the suction excavation technique. The tumor’s dimensions were 3.5 cm × 2.8 cm × 2.5 cm. The tumor was positive for C-KIT and CD34 by immunohistochemical staining. The mitotic count was 6/50 high-power fields. The patient was followed for 5 years without tumor recurrence. This case demonstrated the use of endoscopic resection of an exophytic GIST using the suction excavation technique as a potential therapy without surgical resection. PMID:27340363

Roux-en-Y gastric bypass (RYGB) is amongst the commonest surgical intervention for weight loss in obese patients. Gastrocutaneous fistula, which usually occurs along the vertical staple line of the pouch, is amongst its most alarming complications. Medical management comprised of wound drainage, nutritional support, acid suppression, and antibiotics may be ineffective in as many as a third of patients with this complication. We present outcomes after endoscopic application of SurgiSIS, which is a novel biomaterial for the treatment of this complication. A case series of 25 patients. Twenty-five patients who had failed conservative medical management of gastrocutaneous fistula after RYGB underwent endoscopic application of SurgiSIS--an acellular fibrogenic matrix biomaterial to help fistula healing. Fistula closure as assessed by upper gastrointestinal imaging and endoscopic examination. In patients who had failed medical management lasting 4-25 (median, 7) weeks, closure of the fistulous tract was successful after one application in six patients (30%), two applications in 11 patients (55%), and three applications in three patients (15%). There were no procedure-related complications. Endoscopic application of SurgiSIS-an acellular fibrogenic matrix--is safe and effective for the treatment of gastrocutaneous fistula after RYGB.

Bleeding esophageal and gastric varices constitute a serious complication in liver cirrhosis. Previous studies have shown that endoscopic ultrasonography (EUS) can be used to predict early esophageal variceal bleeding in liver cirrhosis. We report a case of a 46-year-old man with hepatitis B liver cirrhosis (CTP score, 5; Child-Pugh class, A) who was admitted to our hospital due to a decreased appetite lasting 1 week. He was initially diagnosed with decompensated hepatitis B cirrhosis; an abdominal computed tomography (CT) scan indicated a diagnosis of liver cirrhosis and portal hypertension (PHT). Common endoscopic examination showed no evidence of gastroesophageal varices; EUS revealed distinct varices of the esophageal and gastric veins. Six months after discharge, the patient was rehospitalized because of upper gastrointestinal bleeding. Endoscopic ligation was implemented as well as esophageal varices loop ligature (EVL). Six months later, EUS showed obvious collateral and perforator veins. We should strongly recommend that patients with liver cirrhosis undergo EUS in addition to a routine endoscopic examination. EUS can play an important role in evaluating the risk for bleeding in PHT and can be used to assess the efficacy of EVL.
Endoscopic therapy in early adenocarcinomas (Barrett's cancer) of the esophagus.

The incidence of early esophageal adenocarcinoma has been increasing significantly in recent decades. Prognosis depends greatly on the choice of treatment. Early cancers can be treated by endoscopic resection, whereas advanced carcinomas have to be sent for surgery. Esophageal resection is associated with high perioperative mortality (1-5%) even in specialized centers. Early diagnosis enables curative endoscopic treatment option. Patients with gastrointestinal symptoms and a familial risk for esophageal cancer should undergo upper gastrointestinal endoscopy. High-definition endoscopes have been developed with technical add-on that helps endoscopists to find fine irregularities in the esophageal mucosa, but interpreting the findings remains challenging. In this review we discussed novel and old diagnostic procedures and their values, as well as our own recommendations and those of the authors discussed for the diagnosis and treatment of early Barrett's carcinoma. Endoscopic resection is the therapy of choice in early esophageal adenocarcinoma. It is mandatory to perform a subsequent ablation of all residual Barrett's mucosa to avoid metachronous lesions. © 2015 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

There a shortage of robust information about profiles of gastrointestinal disease in sub-Saharan Africa. The endoscopy unit of the University Teaching Hospital in Lusaka has been running without interruption since 1977 and this 38-year record is largely intact. We report an analysis of endoscopic findings over this period. Written endoscopy records from 29th September 1977 to 16th December 2014 were recovered, computerised, coded by two experienced endoscopists and analysed. Temporal trends were analysed using tables, graphs, and unconditional logistic regression, with age, sex of patient, decade, and endoscopist as independent variables to adjust for inter-observer variation. Sixteen thousand nine hundred fifty-three records were identified and analysed. Diagnosis of gastric ulcer rose by 22 %, and that of duodenal ulcer fell by 14 % per decade. Endoscopically diagnosed oesophageal cancer increased by 32 % per decade, but gastric cancer rose only in patients under 60 years of age (21 % per decade). Oesophageal varices were the commonest finding in patients presenting with haematemesis, increasing by 14 % per decade in that patient group. Two HIV-related diagnoses, oesophageal candidiasis and Kaposi's sarcoma, rose from almost zero to very high levels in the 1990s but fell substantially after 2005 when anti-retroviral therapy became widely available. This useful dataset suggests that there are important trends in some endoscopic findings over four decades. These trends are not explained by inter-observer variation. Reasons for the divergent trends in incidence of peptic ulceration and apparent trends in diagnosis of upper gastrointestinal cancers merit further exploration.

Abstract At present, we do not know the exact prevalence of Barrett esophagus (BE) developing later in patients without BE in their first endoscopic screening. The purpose of this study was to determine the prevalence of BE on the second endoscopic examination of patients who had no BE in their first endoscopic examination. The data of the patients older than 18 years who had undergone upper gastrointestinal system endoscopy more than once at the endoscopy unit of our clinic during the last 6 years were retrospectively analyzed. During the last 6 years, 44,936 patients had undergone at least one endoscopic examination. Among these patients, 2701 patients who had more than one endoscopic screening were included in the study. Of the patients, 1276 (47.3%) were females and 1425 (52.7%) were males, with an average age of 54.9 (18–94) years. BE was diagnosed in 18 (0.66%) of the patients who had no BE in the initial endoscopic examination. The patients with BE had reflux symptoms in their medical history and in both endoscopies, they revealed a higher prevalence of lower esophageal sphincter laxity, hiatal hernia, and reflux esophagitis when compared to patients without BE (P < 0.001). Our study showed that in patients receiving no diagnosis of BE on their first endoscopic examination performed for any reason, the prevalence of BE on their second endoscopy within 6 years was very low (0.66%).

Patients with an upside-down stomach usually receive surgical treatment. In high-risk patients, endoscopic repositioning and gastropexy can be performed. However, the risk of recurrence after endoscopic treatment is not known. We treated a case of recurrent upside-down stomach after endoscopic therapy that indicated the limits of endoscopic treatment and risk of recurrence. An 88-year-old woman was treated three times for vomiting in the past. She presented to our hospital with periodic vomiting and an inability to eat, and a diagnosis of upside-down stomach was made. Endoscopic repositioning and gastropexy were performed. The anterior stomach wall was fixed to the abdominal wall in three places as widely as possible. Following treatment, she became symptom-free. Three months later, she was hospitalized again because of a recurrent upside-down stomach. Laparoscopic repair of hernias and gastropexy was performed. Using a laparoscope, two causes of recurrence were found. One cause was that the range of adherence between the stomach and the abdominal wall was narrow (from the antrum only to the lower corpus of stomach), so the upper corpus of stomach was rotated and herniated into the esophageal hiatus. The other cause was adhesion between the omentum and the esophageal hiatus which caused the stomach to rotate and repeatedly become herniated. Although endoscopic treatment for upside-down stomach can be a useful alternative method in high-risk patients, its ability to prevent recurrence is limited. Moreover, a repeated case caused by adhesions has risks of recurrence.

Capsule endoscopy performed via the traditional peroral route is technically challenging in patients with dysphagia, gastroparesis, and/or abnormal upper-GI (UGI) anatomy. To describe the indications and outcomes of cases in which the AdvanCE capsule endoscope delivery device, which has recently been cleared by the Food and Drug Administration, was used. Retrospective, descriptive, case series. Tertiary care, university hospital. We report a case series of 16 consecutive patients in whom the AdvanCE delivery device was used. The study period was May 2005 through July 2006. Endoscopic delivery of the video capsule to the proximal small bowel by using the AdvanCE delivery device. Indications, technique, and completeness of small bowel imaging in patients who underwent endoscopic video capsule delivery. The AdvanCE delivery device was used in 16 patients ranging in age from 3 to 74 years. The primary indications for endoscopic delivery included inability to swallow the capsule (10), altered UGI anatomy (4), and gastroparesis (2). Of the 4 patients with altered UGI anatomy, 3 had dual intestinal loop anatomy (ie, Bilroth-II procedure, Whipple surgery, Roux-en-Y gastric bypass) and 1 had a failed Nissen fundoplication. In all cases, the capsule was easily deployed without complication, and complete small intestinal imaging was achieved. Small patient size. Endoscopic placement of the Given PillCam by use of the AdvanCE delivery device was safe and easily performed in patients for whom capsule endoscopy would otherwise have been contraindicated or technically challenging.

Upper airway nerve and muscle damage associated with obstructive sleep apnea may impair the strength and dynamics of pharyngeal and esophageal contractions during swallowing. To evaluate the presence of alterations in pharyngoesophageal manometry in patients with obstructive sleep apnea with and without oropharyngeal dysphagia. This study prospectively evaluated 22 patients with obstructive sleep apnea without spontaneous complaints of dysphagia, using a questionnaire, fiberoptic endoscopic evaluation of swallowing, and pharyngoesophageal manometry, including measurement of the upper and lower esophageal sphincter pressures and mean pharyngeal pressures at three levels during swallowing. The dysphagia group consisted of 17 patients (77.3%) in whom swallowing abnormalities were detected on fiberoptic endoscopic evaluation of swallowing (n=15; 68.2%) and/or in the questionnaire (n=7; 31.8%). The five remaining cases comprised a control group without oropharyngeal dysphagia. In all cases of abnormalities on fiberoptic endoscopic evaluation of swallowing, there was premature bolus leakage into the pharynx. There was no statistically significant difference between the groups regarding any of the pharyngoesophageal manometry measurements, age, or severity of obstructive sleep apnea. Pharyngoesophageal manometry detected no statistically significant difference between the groups with and without oropharyngeal dysphagia.

This study describes the case of the youngest patient ever reported with ampullary adenoma. The incidence of ampullary adenomas in childhood is unknown. Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound are used in adults to assess and treat these lesions, although there are no instruments designed specifically for use in young children. A six-year-old girl was admitted for abdominal pain, vomiting, pruritus and weight loss. Abdominal ultrasound showed biliary tree (8mm) and pancreatic duct dilatation (4mm). Magnetic resonance cholangiopancreatography and computed tomography confirmed these findings, and also showed displacement of the ampulla to the left upper quadrant. An upper endoscopy confirmed a large ampullary adenoma. A laparotomy was performed and a 5cm villous tumour arising from the ampulla was excised. The postoperative course was uneventful. The histology demonstrated adenoma of the ampulla (intestinal type) without low-grade dysplasia. all clinical and radiological parameters are normal at 20 months follow-up. We describe the case of the youngest patient ever reported with ampullary adenoma. Pancreaticoduodenectomy carries high morbidity and mortality rates, and therefore it should be avoided in absence of histologically proven malignancy. We believe that surgical ampullectomy is a safe and oncologically correct procedure until better endoscopic instruments for peadiatric use will be designed.

Objectives To evaluate the efficacy and safety of using a buccal fat pad for endoscopic skull base defect reconstruction. Design Descriptive anatomical study with an illustrative case presentation. Setting Anatomical study was performed on 12 fresh human cadaver specimens with injected arteries (24 sides). Internal carotid artery was exposed in the coronal plane via the endoscopic transpterygoid approach. The pedicled buccal fat pad was used for reconstruction. Participants: 12 human cadaver head specimens; one patient operated using the proposed technique. Main outcome measures: Proximity of the buccal fat pad flap to the defect, compliance of the flap, comfort and safety of harvesting procedure, and compatibility with the Hadad–Bassagasteguy nasoseptal flap. Results: Harvesting procedure was performed using anterior transmaxillary corridor. The pedicled buccal fat pad flap can be used to pack the sphenoid sinus or cover the internal carotid artery from cavernous to upper parapharyngeal segment. Conclusion The buccal fat pad can be safely harvested through the same approach without external incisions and is compliant enough to conform to the skull base defect. The proposed pedicled flap can replace free abdominal fat in central skull base reconstruction. The volume of the buccal fat pad allows obliteration of the sphenoid sinus or upper parapharyngeal space. PMID:28180047

The purpose of this study was to determine the effects of trial (i.e., Trial 1 vs. Trial 2); viscosity (i.e., saliva, thin, nectar-thick, honey-thick, and pudding-thick water); volume (i.e., 5 mL vs. 10 mL); age (i.e., young vs. older adults); and gender on pharyngeal (i.e., upper and lower) and upper esophageal sphincter (UES) pressures, durations, and onsets (i.e., onset of upper pharyngeal pressures relative to onsets of UES relaxations and onset of lower relative to upper pharyngeal pressures). Twenty-three young adults (M=30 years) and 21 older healthy adults (M=75 years) participated. Measurements were acquired with a 2.1-mm catheter during simultaneous manometric and endoscopic swallowing assessment. Participants contributed 18 swallows, affording a study total of 792 swallows for analyses. There was no significant effect of trial on any measurement of pressure, duration, and onset (ps=.63, .39, and .71, respectively). It was found that viscosity, volume, age, and gender affected pressure, duration, and onset measurements (e.g., onset of upper pharyngeal pressures relative to onsets of UES relaxations) but in varying degrees relative to the location in the pharynx or UES and the type of measurement (e.g., pressure, onset). Manometric measurements vary with respect to age, gender, and bolus variables and interactions of each. Consideration of these variables is paramount in understanding normal and pathological swallowing if manometry is to develop as a quantitative adjunct to videofluoroscopic and endoscopic swallowing tools.

To propose a less invasive surgical treatment for schistosomal portal hypertension. Ten consecutive patients with hepatosplenic schistosomiasis and portal hypertension with a history of upper gastrointestinal hemorrhage from esophageal varices rupture were evaluated in this study. Patients were subjected to a small supraumbilical laparotomy with the ligature of the splenic artery and left gastric vein. During the procedure, direct portal vein pressure before and after the ligatures was measured. Upper gastrointestinal endoscopy was performed at the 30(th) postoperative day, when esophageal varices diameter were measured and band ligature performed. During follow-up, other endoscopic procedures were performed according to endoscopy findings. There was no intra-operative mortality and all patients had confirmed histologic diagnoses of schistosomal portal hypertension. During the immediate postoperative period, two of the ten patients had complications, one characterized by a splenic infarction, and the other by an incision hematoma. Mean hospitalization time was 4.1 d (range: 2-7 d). Pre- and post-operative liver function tests did not show any significant changes. During endoscopy thirty days after surgery, a decrease in variceal diameters was observed in seven patients. During the follow-up period (57-72 mo), endoscopic therapy was performed and seven patients had their varices eradicated. Considering the late postoperative evaluation, nine patients had a decrease in variceal diameters. A mean of 3.9 endoscopic banding sessions were performed per patient. Two patients presented bleeding recurrence at the late postoperative period, which was controlled with endoscopic banding in one patient due to variceal rupture and presented as secondary to congestive gastropathy in the other patient. Both bleeding episodes were of minor degree with no hemodynamic consequences or need for blood transfusion. Ligature of the splenic artery and left gastric vein with supraumbilical laparotomy is a promising and less invasive method for treating presinusoidal schistosomiasis portal hypertension.

Adenomas are frequently encountered in the lower digestive tract but are rarely diagnosed in the biliary tree. We report a case of villous adenoma of the common hepatic duct. A 58-year old male was admitted with a four week history of intermittent upper right quadrant pain. Gray scale and contrast-enhanced abdominal ultrasound showed a mass inside the common hepatic duct with arterial enhancement and slow wash-out during the late venous phase. Subsequent endoscopic retrograde cholangiopancreatography and intraductal ultrasound confirmed the presence of the lesion. The final histopathological examination showed villous adenoma of the common hepatic duct with high-grade dysplasia. Contrast enhanced ultrasonography used in conjecture with endoscopic retrograde cholangiopancreatography can help in differentiating biliary tumors.

Self-expandable metal stents (SEMS) and self-expandable plastic stents (SEPS) maybe used for the treatment of benign upper gastrointestinal (GI) leaks and strictures. This study reviewed our experience with stent insertions in patients with benign upper GI conditions. Patients who underwent stent placement for benign upper GI strictures and leaks between March 2007 and April 2011 at a tertiary referral academic center were studied using an endoscopic database and electronic patient records. The technical success, complications, and clinical improvement after stent removal were compared according to type of stent. The outcomes measured were clinical response, adverse events, and predictors of stent migration. Thirty-eight patients (50 % male, mean age = 54 years, range = 12-82) underwent 121 endoscopic procedures. Twenty patients had stents placed for strictures, and 18 had stents placed for leaks. Stent placement was technically successful in all patients. The average duration of stent placement was 54 days (range = 18-118). Clinical improvement immediately after stent placement was seen in 29 of the 38 patients (76.3 %). Immediate post-procedure adverse events occurred in 8 patients. Late adverse events were seen in 18 patients. Evidence of stent migration occurred in 16 patients and was seen in 42 of the 118 successfully placed stents (35.5 %). Migration was more frequent with fully covered SEMS (p = 0.002). After stent removal, 27 patients were evaluable for long-term success (median follow-up time of 283 days, IQR 38-762). Resolution of strictures or leaks was seen in 11 patients (40.7 %). Predictors for long-term success included increasing age and if the stent did not cross the GE junction. Placement of SEPS and SEMS for benign refractory strictures and fistulas has modest long-term clinical efficacy and is limited by a significant migration rate. Stent migration is common and frequent with fully covered SEMS compared to other types of stents, regardless of indication or location.

Current guidelines recommend upper endoscopic screening for patients with hepatic cirrhosis and primary prophylaxis with a nonselective beta-blocker for those with large varices. However, only 25% of cirrhotics develop large varices. Thus, the aim of this study is to evaluate the most cost-effective approach for primary prophylaxis of variceal hemorrhage. Using a Markov model, we compared the costs and clinical outcomes of three strategies for primary prophylaxis of variceal bleeding. In the first strategy, patients were given a beta-blocker without undergoing upper endoscopy. In the second strategy, patients underwent upper endoscopic screening; those found to have large varices were treated with a beta-blocker. In the third strategy, no prophylaxis was used. Selected sensitivity analyses were performed to validate outcomes. Our results show screening prophylaxis was associated with a cost of $37,300 and 5.72 quality-adjusted life yr (QALYs). Universal prophylaxis was associated with a cost of $34,100 and 6.65 QALYs. The no prophylaxis strategy was associated with a cost of $36,600 and 4.84 QALYs. The incremental cost-effectiveness ratio was $800/QALY for the endoscopic strategy relative to the no prophylaxis strategy. Screening endoscopy was cost saving when the compliance, bleed risk without beta-blocker, and variceal bleed costs were increased, and when the discount rate, bleed risk on beta-blockers, and cost of upper endoscopy were decreased. In contrast, the universal prophylaxis strategy was persistently cost saving relative to the no prophylaxis strategy. In comparing the strategies, sensitivity analysis on the death rates from variceal hemorrhage did not alter outcomes. Our results provide economic and clinical support for primary prophylaxis of esophageal variceal bleeding in patients with hepatic cirrhosis. Universal prophylaxis with beta-blocker is preferred because it is consistently associated with the lowest costs and highest QALYs.

Advances in Endoscopic submucosal dissection (ESD) technology have established ESD for early gastric cancer as a safe and stable technique. However, ESD may induce delayed gastric emptying and the cause of food residue retention in the stomach after ESD is not clear. This study aimed to clarify risk factors for delayed gastric emptying with food retention after gastric ESD. We retrospectively examined for food residue in the stomach 1 week after ESD was performed for early gastric carcinoma at Osaka Saiseikai Nakatsu Hospital from February 2008 to November 2016. Food residue was observed in 68 (6.1%) of 1114 patients who underwent gastric ESD. The percentage of lesions located on the lesser curvature of the upper third of the stomach was 45.6% (31/68) in the food residue group and 3.5% (37/1046) in the non-food residue group, which was significantly different (P < 0.01). Multivariate logistic regression analysis revealed that lesions on the lesser curvature of the upper third of the stomach (Odds ratio [OR] 23.31, 95% confidence interval [CI] 12.60-43.61, P < 0.01), post-ESD bleeding (OR 4.25, 95%CI 1.67-9.80, P < 0.01), submucosal invasion (OR 2.80, 95%CI 1.34-5.63, P < 0.01), and age over 80 years (OR 2.34, 95%CI 1.28-4.22, P < 0.01) were independent risk factors for food retention after gastric ESD. Of the 68 patients, 3 had food residue in the stomach on endoscopic examination for follow-up observation after the ESD ulcer had healed. Delayed gastric emptying with food retention after gastric ESD was associated with lesions located in the lesser curvature of the upper stomach, submucosal invasion of the lesion, age older than 80 years, and post-ESD bleeding, though it was temporary in most cases.

Gastric bezoars are rare and are usually found incidentally. They can sometimes cause severe complications, including gastric outlet obstruction (GOO) or gastric pneumatosis (GP). In cases of bezoars with GP, the optimal treatment strategy has not yet been defined. We report the case of an 89-year-old man with a history of type 2 diabetes mellitus and hypertension who presented to our emergency room with a 2-day history of upper abdominal pain, nausea, and vomiting. Physical examination revealed no rebound tenderness or guarding, and laboratory values revealed no elevation of the serum lactate level. A computed tomography scan of the abdomen showed a dilated stomach with significant fluid collection, GOO, and GP due to a 42 × 40 mm mass composed of fat and air densities. Emergency esophagogastroduodenoscopy revealed two gastric bezoars, one of which was incarcerated in the pyloric region. We used various endoscopic devices to successfully break and remove the bezoars. We used endoscopic forceps and a water jet followed by an endoscopic snare to cut the bezoars into several pieces and remove them with an endoscopic net. Follow-up endoscopy confirmed that the gastric bezoar had been completely removed. As seen in this case, endoscopic treatment may be a safe and viable option for the extraction of gastric bezoars presenting with GOO and GP. PMID:29430223

To characterize the associations between clinical signs of nasopharyngeal cicatrix syndrome (NCS) and endoscopic findings in horses. Retrospective, case-control study. 239 horses (118 case horses and 121 control horses). Medical records of horses that had an endoscopic evaluation of the upper airway performed between January 2003 and December 2008 were reviewed. Clinical signs and the appearance and anatomic locations of lesions identified during endoscopic evaluation were reviewed and recorded for each horse. The associations between clinical signs and endoscopic findings were evaluated by the use of a prospective logistic model that used a Bayesian method for inference and was implemented by a Markov chain Monte Carlo method. Nasal discharge was associated with acute inflammation of the pharynx and larynx. Exercise intolerance was associated with circumferential pharyngeal lesions. Respiratory noise was associated with chronic scarring of the pharynx, a combination of pharyngeal and laryngeal scarring, and circumferential scarring of the pharynx. Respiratory distress was associated with acute inflammation of all portions of the airway, especially when there was preexisting scarring and narrowing of the airway by ≥ 50%. Cough did not have any significant association with NCS, compared with results in control horses. Associations between the endoscopic appearance of NCS lesions and relevant clinical signs will help practitioners identify horses with NCS and allow them to select appropriate treatment.

Transnasal endoscopy (TNE) is an upper endoscopy method which is performed by the nasal route using a thin endoscope less than 6 mm in diameter. The primary goal of this method is to improve patient tolerance and convenience of the procedure. TNE can be performed without sedation and thus eliminates the risks associated with general anesthesia. In this way, TNE decreases the cost and total duration of endoscopic procedures, while maintaining the image quality of standard caliber endoscopes, providing good results for diagnostic purposes. However, the small working channel of the ultra-thin endoscope used for TNE makes it difficult to use for therapeutic procedures except in certain conditions which require a thinner endoscope. Biopsy is possible with special forceps less than 2 mm in diameter. Recently, TNE has been used for screening endoscopy in Far East Asia, including Japan. In most controlled studies, TNE was found to have better patient tolerance when compared to unsedated endoscopy. Nasal pain is the most significant symptom associated with endoscopic procedures but can be reduced with nasal pretreatment. Despite the potential advantage of TNE, it is not common in Western countries, usually due to a lack of training in the technique and a lack of awareness of its potential advantages. This paper briefly reviews the technical considerations as well as the potential advantages and limitations of TNE with ultra-thin scopes.

We report a case of chronic debilitating BPF following right upper lobe resection. Despite several endobronchial applications of fibrin glue, we could not close it. Since the patient was extremely debilitated by symptoms due to the BPF, a thoracoplasty was attempted but was not successful. Finally, the BPF was definitely closed by instillation of talc into the pleura through thoracoscopy. To our knowledge, this is the first reported case of chemical closure of a recalcitrant BPF by the route of thoracoscopy. It also shows the failure of endoscopic fibrin glue application in such a condition.

The ingestion of a foreign body is one of the most common endoscopic emergencies. Foreign bodies in the upper gastrointestinal tract should be extracted as soon as possible to avoid serious complications such as perforation o bleeding. However, removals of foreign bodies with sharp edges are very difficult and can develop complications during their removal. Various devices have therefore been developed to prevent mucosal injury from the sharp edges during endoscopic extraction. We report a new technique for the successful foreign body extraction of upper digestive tract using the cap from six shooter variceal banding reused. We present 17 cases (9 males and 8 females). The types of foreign bodies removed were: chicken bones (n:7), fish bones (n:3), denture prosthesis (n:2), food bolus (n:2), long pin (n:1), golden thumb tack (n: 1) and press-through package (n:1). There were no complications. This new technique is safe and effective. Highlights its advantages: enhanced sight pharyngo esophageal junction, foreign bodies disimpact at that level, food bolus suck, avoid sharp object damage mucosal or scope and decrease time removal.

Examination of the equine upper airway during racing has not previously been documented. To describe the feasibility and appearance of the upper airways by overground respiratory endoscopic examination during racing conditions. Overground videoendoscopic examinations were performed on 46 Standardbred racehorses during qualifying races. Examined horses' speeds were recorded throughout the race with a portable GPS device. The procedure did not interfere with performance as there were no significant differences in race times between races in which horses were examined with the endoscope in place and prior unexamined races. Airway obstructions during or after the race were documented in 21 horses. Most previously reported causes of upper airway obstruction were observed; surprisingly bilateral ventro-medial arytenoid displacement (VMAD; n = 5) was seen during exercise as frequently as dorsal displacement of the soft palate (DDSP). Although DDSP (n = 10) was the most common diagnosis made, many displacements (n = 5) occurred after the race. Horses that demonstrated DDSP after the race had slower speeds than unaffected horses during the race. Racing endoscopy permits the diagnosis of upper airway obstructions without affecting performance. The occurrence of DDSP immediately after exercise may be clinically relevant. During racing VMAD may be an important anomaly. Racing endoscopy could be used to correlate the sensitivity of diagnostic endoscopy during race-training or treadmill examination. The pathogenesis and significance of VMAD deserves further investigation. © 2012 EVJ Ltd.
Efficacy of deep biopsy for subepithelial lesions in the upper gastrointestinal tract.

Accurate diagnosis of subepithelial lesions (SELs) in the gastrointestinal tract depends on a variety of methods: endoscopy, endoscopic ultrasound and different types of biopsy. Making an error-free diagnosis is vital for the subsequent application of an appropriate treatment. To evaluate the efficacy of deep biopsy via the endoscopic submucosal dissection (ESD) technique for SELs in the upper gastrointestinal tract. It was a case series study. Deep biopsy via the ESD technique was completed in 38 patients between November 2012 and October 2014. Thirty-eight SELs in the upper gastrointestinal tract of varying size (very small ≤ 1 cm, small 1-2 cm and large ≥ 2 cm) by means of the ESD technique after an incision with an electrosurgical knife of the overlying layers and revealing a small part of the lesion were biopsied under direct endoscopic view. Deep biopsy via the ESD technique was diagnostic in 28 of 38 patients (73.3%; 95% CI: 59.7-89.7%). The diagnostic yield for SELs with a clear endophytic shape increased to 91.3%. An evident endophytic appearance of a subepithelial lesion, the mean number of biopsied samples (6.65 ±1.36) and the total size in length of all samples per case (19.88 ±8.07 mm) were the main criteria influencing the positiveness of deep biopsy in the diagnostic group compared to the nondiagnostic one (p = 0.001; p = 0.025; p = 0.008). Deep biopsy via the ESD technique is an effective and safe method for the diagnosis of SELs especially with a clear endophytic appearance in a large number of biopsied samples.

To compare the efficacy and safety of a hook knife (HO) with a hybrid knife (HK) during endoscopic submucosal tunnel dissection (ESTD) procedure. Between August 2012 and December 2015, the ESTD procedure was performed for 83 upper GI submucosal lesions, which originated from the muscularis propria layer identified by upper endoscopy and endoscopic ultrasonography. Of these, 34 lesions were treated by a HO, whereas 49 lesions were treated by a HK. Data regarding age, gender, presenting symptoms, tumor location and size, procedure time, complications, en bloc resection rate and others were analyzed and compared between the two groups. There were no significant differences in the age, gender, presenting symptoms and tumor location between the two groups. ESTD was successfully completed in all the patients, and no case was converted to laparoscopy. The mean procedure time was significantly shorter in the HK group than in the HO group (41.3 ± 20.3 min vs 57.2 ± 28.0 min, P = 0.004). The mean frequency of device exchange was 1.4 ± 0.6 in the HK group and significantly less than 3.3 ± 0.6 in the HO group ( P < 0.001). The differences in tumor size and histopathological diagnoses were not significant between the two groups ( P = 0.813, P = 0.363, respectively). Both groups had an equal en bloc resection rate and complete resection rate. Additionally, the complication rate was similar between the two groups ( P = 0.901). During the follow-up, no recurrence occurred in either group. We demonstrate for the first time that HO and HK do not differ in efficacy or safety, but HK reduces the frequency of device exchange and procedure time.

To investigate the efficacy and clinical outcome of patients treated with an over-the-scope-clip (OTSC) system for severe gastrointestinal hemorrhage, perforations and fistulas. From 02-2009 to 10-2012, 84 patients were treated with 101 OTSC clips. 41 patients (48.8%) presented with severe upper-gastrointestinal (GI) bleeding, 3 (3.6%) patients with lower-GI bleeding, 7 patients (8.3%) underwent perforation closure, 18 patients (21.4%) had prevention of secondary perforation, 12 patients (14.3%) had control of secondary bleeding after endoscopic mucosal resection or endoscopic submucosal dissection (ESD) and 3 patients (3.6%) had an intervention on a chronic fistula. In 78/84 patients (92.8%), primary treatment with the OTSC was technically successful. Clinical primary success was achieved in 75/84 patients (89.28%). The overall mortality in the study patients was 11/84 (13.1%) and was seen in patients with life-threatening upper GI hemorrhage. There was no mortality in any other treatment group. In detail OTSC application lead to a clinical success in 35/41 (85.36%) patients with upper GI bleeding and in 3/3 patients with lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases (57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18 (100%) patients for the prevention of bleeding or perforation after endoscopic mucosal resection and ESD and in 3/3 cases of fistula closure. Two application-related complications were seen (2%). This largest single center experience published so far confirms the value of the OTSC for GI emergencies and complications. Further clinical experience will help to identify optimal indications for its targeted and prophylactic use.

Endoscopic hemostasis is a useful treatment modality for gastric ulcer bleeding. However, it is sometimes difficult to achieve hemostasis in cases with arterial bleeding, especially those complicated with vascular abnormalities. We describe a case with gastric ulcer bleeding from a variant left gastric artery accompanied by congenital absence of the splenic artery. A 50-year-old female was admitted to our hospital with dizziness and tarry stools. Upper gastrointestinal endoscopy revealed bleeding from a gastric ulcer, and endoscopic hemostasis by endoscopic clipping was carried out. Computed tomography and abdominal angiography revealed the variant left gastric artery running below the gastric ulcer. In spite of endoscopic hemostasis and medication, re-bleeding from the gastric ulcer occurred. A transcatheter coil embolization for the variant left gastric artery was performed and successfully achieved hemostasis. This case was accompanied by congenital absence of the splenic artery, which is an extremely rare condition. We herein describe this rare case and review previously reported cases.

Patients with an upside-down stomach usually receive surgical treatment. In high-risk patients, endoscopic repositioning and gastropexy can be performed. However, the risk of recurrence after endoscopic treatment is not known. We treated a case of recurrent upside-down stomach after endoscopic therapy that indicated the limits of endoscopic treatment and risk of recurrence. An 88-year-old woman was treated three times for vomiting in the past. She presented to our hospital with periodic vomiting and an inability to eat, and a diagnosis of upside-down stomach was made. Endoscopic repositioning and gastropexy were performed. The anterior stomach wall was fixed to the abdominal wall in three places as widely as possible. Following treatment, she became symptom-free. Three months later, she was hospitalized again because of a recurrent upside-down stomach. Laparoscopic repair of hernias and gastropexy was performed. Using a laparoscope, two causes of recurrence were found. One cause was that the range of adherence between the stomach and the abdominal wall was narrow (from the antrum only to the lower corpus of stomach), so the upper corpus of stomach was rotated and herniated into the esophageal hiatus. The other cause was adhesion between the omentum and the esophageal hiatus which caused the stomach to rotate and repeatedly become herniated. Although endoscopic treatment for upside-down stomach can be a useful alternative method in high-risk patients, its ability to prevent recurrence is limited. Moreover, a repeated case caused by adhesions has risks of recurrence. PMID:24574947

The main object of this work was to determine the role and place of esophagogastroduodenoscopy (EGDS) in the diagnostic diseases upper portion of the gastrointestinal tract. We analysed endoscopic pictures of patients, which have HIV and active form of tuberculosis (T. B.). 141 patients with HIV/T. B., who are on the treatment in Tubercular hospital No 11 of Moscow, were examined during 2008 year. About 86% of patients (121 of 141) had a positive endoscopic picture of gastroesophageal reflux disease (GERB). About 69.5% of patients had a mycotic lesion of esophagus: 52 patients (17.8%) had a mycotic lesion of esophagus, which was visually discovered by EGDS; mycotic lesion of esophagus was confirmed by method of polymerase chain reaction (PCR (at 46 patients (51.7%)). The smear for identification micobacteria of tuberculosis was taken from 52 patients (from group 89 patients) with negative endoscopic picture of a mycotic lesion by method PCR additionally. The results have shown, that 23 patients have a positive reaction (43.4%). A diagnostic bronchoscopy was made to examed group. 20 patients from 141 with HIV (14.9%) had a positive result PCR of mycotic lesion. It shows that a defeat of candidosis take place not only in the gastrointestinal tract, but also in the bronchial tree. EGDS+ PCR+ histology is the basis method of the diagnostic diseases upper portion of the gastrointestinal tract. This research established that almost 70% of patients with HIV/T. B. have mycotic lesion of esophagus and 86%--defeat of GERB. That's why, we recommend to include proton- pump inhibitors and antimycotic preparations in the scheme of patient's treatment.
Management of Patients with Acute Lower Gastrointestinal Bleeding
Strate, Lisa L.; Gralnek, Ian M.

This guideline provides recommendations for the management of patients with acute overt lower gastrointestinal hemorrhage. Hemodynamic status should be initially assessed with intravascular volume resuscitation started as needed. Risk stratification based upon clinical parameters should be performed to help distinguish patients at high and low-risk of adverse outcomes. Hematochezia associated with hemodynamic instability may be indicative of an upper GI bleeding source and thus warrants an upper endoscopy. In the majority of patients, colonoscopy should be the initial diagnostic procedure and should be performed within 24 hours of patient presentation after adequate colon preparation. Endoscopic hemostasis therapy should be provided to patients with high risk endoscopic stigmata of bleeding including active bleeding, non-bleeding visible vessel, or adherent clot. The endoscopic hemostasis modality used (mechanical, thermal, injection or combination) is most often guided by the etiology of bleeding, access to the bleeding site, and endoscopist experience with the various hemostasis modalities. Repeat colonoscopy, with endoscopic hemostasis performed if indicated, should be considered for patients with evidence of recurrent bleeding. Radiographic interventions (tagged red blood cell scintigraphy, CT angiography, angiography) should be considered in high-risk patients with ongoing bleeding who do not respond adequately to resuscitation, and who are unlikely to tolerate bowel preparation and colonoscopy. Strategies to prevent recurrent bleeding should be considered. NSAID use should be avoided in patients with a history of acute lower GI bleeding particularly if secondary to diverticulosis or angioectasia. In patients with established cardiovascular disease who require aspirin (secondary prophylaxis), aspirin should not be discontinued. The exact timing depends on the severity of bleeding, perceived adequacy of hemostasis and the risk of a thromboembolic event. Surgery for the prevention of recurrent lower gastrointestinal bleeding should be individualized and the source of bleeding should be carefully localized prior to resection. PMID:26925883

The aim of this clinical investigation was to register the frequency of endoscopically defined diseases of the upper intestinal tract in a given region (Münster and Münsterland) within the period of one year (1.8.1999-31.7.2000). Furthermore, we tried to get an impression on the quality of the upper intestinoscopies by standardised conditions which had been developed by a steering committee (endoscopists and pathologists). 20 physicians (internal specialists and gastroenterologists) examined non-preselected patients and registered all relevant findings in the upper intestinal tract. The following items were of special interest: sex, age, operations in the past, indication, way of preparation, local findings (in the upper intestinal tract), and histological assessment. The examination forms were gathered, checked for completeness and evaluated statistically. Within the given period 8859 examinations forms (45.2% male and 54% female) could be evaluated. In 16% of the patients a reflux oesophagitis was diagnosed, three times more frequently than could have been expected anamnestically regarding the patients' complaints. In 274 patients (3%) the endoscopist suspected a Barrett's oesophagus; the according histological examination confirmed this suspicion in only 125 cases. Furthermore 17 adenocarcinomas and 13 squamous cell carcinomas were found. Macroscopically 44 polyps were registered but not all of them were biopsied. In 257 patients oesophageal varices (of varying degrees) were described. Only in 30.7% of the patients a H. pylori infection (diagnosed by urease test and by histological examination) was detected in the mucosa of the stomach. In 172 patients a gastritis was macroscopically suspected but the following histological assessments were not sufficient. The prevalence of gastric ulcers was 10 %, higher than the prevalence of duodenal ulcers. Only in 50% of the patients with a duodenal ulcer a H. pylori infection could be detected. In 51 cases carcinomas (diagnosis histologically confirmed) were found with the same ratio of the diffuse type and the intestinal type. In 18 patients a carcinoma could be detected in the neighbouring area of gastric ulcers. The endoscopic findings in this investigation do not differ significantly from the results found in literature. It is important that there are more gastric ulcers than duodenal ulcers. This can be explained by the frequent use of PPIs which are prescribed additionally to NSARs and ASS. The deficits of histological diagnostics on Barett's oesophagus and gastritis were remarkable. An improvement of the endoscopic and histologic assessment quality by valid standards systematically applied should be aimed at in future. Furthermore it could be helpful to use the same nomenclature for pathologic findings to intensify the co-operation between the physicians in hospitals and the practitioners.

Background. Foreign object ingestion and food bolus impaction are a common clinical problem. We report our clinical experiences in endoscopic management for adults, foreign body ingestion, and food bolus impaction. Method. A retrospective chart review study was conducted on adult patients with foreign body ingestion and food bolus impaction between January 2011 and November 2014. Patients with incomplete medical records were excluded. Results. A total of 198 patients (226 incidents) were included in the study (male/female: 1.54/1; age 57 ± 16 years). Among them, 168 foreign bodies were found successfully (74.3%). 75.6% of the foreign bodies were located in the esophagus. Food bolus impaction was most common (41.6%). 93.5% of foreign bodies in current study cohort were successfully extracted and 5 patients required surgical interventions. Comparisons between symptomatic and asymptomatic patients revealed that locations of foreign bodies in the pharynx and esophagus were the significant relevant factors (P < 0.001). Shorter time taken to initiate endoscopic interventions increased detection rate (289.75 ± 465.94 versus 471.06 ± 659.93 minutes, P = 0.028). Conclusion. Endoscopic management is a safe and highly effective procedure in extracting foreign body ingestion and food bolus impaction. Prompt endoscopic interventions can increase the chance of successful foreign bodies' detection. PMID:26258140

Pantoprazole for the treatment of peptic ulcer bleeding and prevention of rebleeding.
van Rensburg, Christo J; Cheer, Susan
2012-01-01
Adding proton pump inhibitors (PPIs) to endoscopic therapy has become the mainstay of treatment for peptic ulcer bleeding, with current consensus guidelines recommending high-dose intravenous (IV) PPI therapy (IV bolus followed by continuous therapy). However, whether or not high-dose PPI therapy is more effective than low-dose PPI therapy is still debated. Furthermore, maintaining pH ≥ 4 appears to prevent mucosal bleeding in patients with acute stress ulcers; thus, stress ulcer prophylaxis with acid-suppressing therapy has been increasingly recommended in intensive care units (ICUs). This review evaluates the evidence for the efficacy of IV pantoprazole, a PPI, in preventing ulcer rebleeding after endoscopic hemostasis, and in controlling gastric pH and protecting against upper gastrointestinal (GI) bleeding in high-risk ICU patients. The review concludes that IV pantoprazole provides an effective option in the treatment of upper GI bleeding, the prevention of rebleeding, and for the prophylaxis of acute bleeding stress ulcers.

Objective This study aims to analyze the clinical and endoscopic presentations of upper gastrointestinal bleeding (UGIB) in the Chinese children. Methods A 10-year retrospective study was made on children with UGIB and undertaken esophagogastroduodenoscopy (EGD) from 4 tertiary referral centers in China. Results Of the 1218 children studied, the bleeding source was found in 76.4%. Erosive gastritis was the most common endoscopic finding (33.5%), followed by duodenal ulcer (23.2%). The proportion of erosive gastritis decreased with age (correlation coefficient = -0.787), and duodenal ulcer increased with age (correlation coefficient = 0.958). The bleeding source was more likely to be determined in children having EGDs within 48 hours (80.6% vs 67.9%). Conclusions In Chinese children with UGIB, erosive gastritis and duodenal ulcer were the leading causes, and their proportions varied with age. EGDs performed within 48 hours may improve the possibility of finding the source of bleeding. © The Author(s) 2015.

About 40% of the general population report dyspepsia at some time in their life making it a fairly common disease. Uncomplicated dyspepsia refers to patients whose dyspepsia is not accompanied by alarm features or associated with NSAIDS usage. To assess the need for UGI Endoscopy and find out the patterns of different endoscopic presentations in patients presenting with uncomplicated dyspepsia. Our study conducted in KR Hospital, Mysore, Department of General Surgery is a retrospective endoscopic study of 1450 patients with uncomplicated dysepsia. A significant 64% of the patients presenting with uncomplicated dyspepsia were found to have findings on endoscopy. The most common age range for positive endoscopic findings was 40-50 years in our hospital. Malignancy was diagnosed in 2.5% patients. We recommend upper GI endoscopy in patients presenting with uncomplicated dyspepsia for patients above 40 years of age in our hospital.

Fascioliasis is an endemic zoonotic disease in Iran. It occurs mainly in sheep-rearing areas of temperate climates, but sporadic cases have been reported from many other parts of the world. The usual definitive host is the sheep. Humans are accidental hosts in the life cycle of Fasciola. Typical symptoms may be associated with fascioliasis, but in some cases diagnosis and treatment may be preceded by a long period of abdominal pain and vague gastrointestinal symptoms. We report a case with epigastric and upper quadrant abdominal pain for the last 6 months, with imaging suggesting liver abscess and normal biliary ducts. The patient had no eosinophilia with negative stool examinations, so she was initially treated with antibiotics for liver abscess. Her clinical condition as well as follow-up imagings showed appropriate response after antibiotic therapy. Finally, endoscopic ultrasonography revealed Fasciola hepatica, which was then extracted with endoscopic retrograde cholangiopancreatography.

Medical and Endoscopic Management of Gastric Varices
Al-Osaimi, Abdullah M. S.; Caldwell, Stephen H.
2011-01-01
In the past 20 years, our understanding of the pathophysiology and management options among patients with gastric varices (GV) has changed significantly. GV are the most common cause of upper gastrointestinal bleeding in patients with portal hypertension after esophageal varices (EV) and generally have more severe bleeding than EV. In the United States, the majority of GV patients have underlying portal hypertension rather than splenic vein thrombosis. The widely used classifications are the Sarin Endoscopic Classification and the Japanese Vascular Classifications. The former is based on the endoscopic appearance and location of the varices, while the Japanese classification is based on the underlying vascular anatomy. In this article, the authors address the current concepts of classification, epidemiology, pathophysiology, and emerging management options of gastric varices. They describe the stepwise approach to patients with gastric varices, including the different available modalities, and the pearls, pitfalls, and stop-gap measures useful in managing patients with gastric variceal bleed.

We describe the treatment of a patient with long-gap esophageal atresia with an upper pouch fistula, mircogastria and minimal distal esophageal remnant. After 4.5 months of feeding via gastrostomy, a proximal fistula was identified by bronchoscopy and a thoracoscopic modified Foker procedure was performed reducing the gap from approximately 7-5 cm over 2 weeks of traction. A second stage to ligate the fistula and suture approximate the proximal and distal esophagus resulted in a gap of 1.5 cm. IRB and FDA approval was then obtained for endoscopic placement of 10-French catheter mounted magnets in the proximal and distal pouches promoting a magnetic compression anastomosis (magnamosis). Magnetic coupling occurred at 4 days and after magnet removal at 13 days an esophagram demonstrated a 10 French channel without leak. Serial endoscopic balloon dilation has allowed drainage of swallowed secretions as the baby learns bottling behavior at home.

Here we report the case of a 34-year-old man who underwent endoscopic removal of a tablespoon from the stomach that was lodged within the duodenum. Removal required the use of a two-channel upper endoscope and polypectomy snares. Using the double-snare technique, the spoon was grasped at the proximal and distal parts of the handle. The double-snare was first pulled unsuccessfully and then pulled with simultaneous manual abdominal compression of the bulbus from the body surface. Compression was gently applied towards the stomach. As a result, the head of the spoon prolapsed from the bulbus, and was easily retracted from the stomach without any complications. In cases of foreign body lodging within the duodenum, the manual abdominal compression technique may help clinicians pull out the object and avoid surgery. The usefulness of manual compression is dependent on the foreign body’s sharpness and the location. PMID:25945026

Pharyngo-esophageal stenosis (PES) and upper esophageal stricture are common in patients who receive radiation therapy for laryngeal and hypopharyngeal cancers. In severe or complete stenosis, the patients generally have complete dysphagia with inability to swallow their saliva. Diagnostic and therapeutic esophagogastroduodenoscopy (EGD) plays an important role in investigating the dysphagia and in managing the underlying stenosis. We translate endoscopic retrograde cholangiopancreatography (ERCP) techniques and skills in approaching pancreaticobiliary obstruction in the management of severe and complete PES. We select and report three cases of severe or complete PES in which flexible endoscopic therapy was successfully provided by using fluoroscopy, ERCP wire guides, endoscopic balloons, and by performing pharyngo-esophageal puncture (PEP). We propose the term PEP in managing complete PES. We believe this approach can offer safety and efficiency with very high success rate.

Multi-detector-row computed tomography (MDCT) has been reported to be a potentially useful modality for detection of the bleeding origin in patients with acute upper massive gastrointestinal (GI) bleeding. The purpose of this study is to investigate the efficacy of MDCT as a routine method for detecting the origin of acute upper GI bleeding prior to urgent endoscopy. Five hundred seventy-seven patients with acute upper GI bleeding (514 nonvariceal patients, 63 variceal patients) who underwent urgent upper GI endoscopy were retrospectively analyzed. Patients were divided into three groups: enhanced MDCT, unenhanced MDCT, and no MDCT before endoscopy. The diagnostic accuracy of MDCT for detection of the bleeding origin was evaluated, and the average procedure times needed to endoscopically identify the bleeding origin were compared between groups. Diagnostic accuracy among endoscopists was 55.3% and 14.7% for the enhanced MDCT and unenhanced MDCT groups, respectively. Among nonvariceal patients, accuracy was 50.2% in the enhanced MDCT group, which was significantly better than that in the unenhanced MDCT group (16.5%). In variceal patients, accuracy was significantly better in the enhanced MDCT group (96.4%) than in the unenhanced MDCT group (0.0%). These accuracies were similar to those achieved by expert radiologists. The average procedure time to endoscopic detection of the bleeding origin in the enhanced MDCT group was significantly faster than that in the unenhanced MDCT and no-MDCT groups. Enhanced MDCT preceding urgent endoscopy may be an effective modality for the detection of bleeding origin in patients with acute upper GI bleeding. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

To determine risk factors associated with the development of nasopharyngeal cicatrix syndrome (NCS) in horses. Retrospective case-control study. 242 horses referred for endoscopic evaluation of the upper portion of the respiratory tract (121 horses with NCS and 121 control horses). Medical records of horses that had an endoscopic evaluation of the upper airway performed between January 2003 and December 2008 were reviewed. Signalment, housing management, and season of evaluation were recorded and reviewed for each horse. The associations between clinical signs and endoscopic findings were evaluated by the use of a prospective logistic model that included a Bayesian method for inference. Results-Breed and sex had no significant effect on the risk of having NCS. The risk that a horse had NCS increased significantly with age. Exclusive housing in a stall was protective against the development of NCS. In addition, the amount of pasture turnout had a dose-related effect, with exclusive pasture turnout positively correlated with increased risk of developing NCS, compared with a mixture of pasture turnout and stall confinement. Horses were significantly more likely to be evaluated because of clinical signs of the syndrome during the warm months of the year. The risk factors for NCS identified in this study may support chronic environmental exposure to an irritant or infectious agent as the cause of NCS. Information gained from this study should be useful for investigating the cause of NCS.

Recently, endoscopic clip application devices have undergone redesign and improvements to optimize their clinical use and effectiveness. Initially designed for the treatment of bleeding nonvariceal lesions, these devices are also increasingly used for the closure of perforations, fistulas, and anastomotic leaks. Several clinical studies, both randomized and nonrandomized, have used endoscopic hemoclips for hemostasis. However, no comparative studies have yet been reported in the literature comparing the latest endoscopic clip devices for usability and effectiveness for hemostasis of acute upper GI hemorrhage. We aimed to compare the usability and efficacy of 3 different types of endoscopic clip application devices in an established experimental setting by using a porcine ex-vivo simulator of upper GI hemorrhage. Randomized, controlled, ex-vivo study. Academic medical center. Spurting vessels were created within ex-vivo porcine stomachs as published in prior studies. The vessels were attached to a pressure transducer to record the pressure of the circulating blood replacement. Before the initiation of bleeding, each vessel was randomized to 1 of 3 endoscopic clipping devices: 2 different commonly used hemoclips deployed through the working channel and 1 novel clip deployed via an over-the-scope applications device. Two investigators treated 45 bleeding sites (15 bleeding sites for each device at various randomized locations in the stomach: fundus, body, and antrum). Usability was measured via the endpoints of procedure time and quantity of clips required to achieve hemostasis. Efficacy was measured via the endpoint of pressure increase (Δp) from baseline to after treatment. All of the 45 hemostasis treatments were carried out successfully. The mean procedure times were significantly different among the hemoclips, with the clip deployed in an over-the-scope fashion requiring significantly less time to attain hemostasis compared with the other 2 clips. For number of clips needed to attain hemostasis, the clip deployed in an over-the-scope fashion was significantly superior to the others. There were also significant differences among the changes in pressure (Δp ± SD) among the different hemoclips tested. Ex-vivo study. In this prospective, randomized ex-vivo study, we observed significant differences in the usability (time to achieve hemostasis and number of clips required) and the efficacy (change in pressure achieved by the hemoclips) among the 3 clips. The clip applied in the over-the-scope fashion was superior to the other 2 tested clips with regard to time to achieve hemostasis and number of clips required.

This report describes a novel approach to endoscopically induce bleeding by removing a clot from the bleeding site during angiography for upper gastrointestinal (UGI) hemorrhage. This procedure enabled accurate identification of the bleeding site, allowing for successful targeted embolization despite a negative initial angiogram. Provocative endoscopy may be a feasible and useful option for angiography of obscure bleeding sites in patients with UGI arterial hemorrhage. Copyright © 2016 SIR. Published by Elsevier Inc.

Celiac disease is a common non-communicable disease with varied presentations. Purpose of this study was to find the duodeno-endoscopic features in celiac disease and to compare duodeno-endoscopic and histological findings between typical and atypical celiac disease in children. Hospital based observational study was conducted at Sir Padampat Mother and Child Health Institute, Jaipur from June 2015 to May 2016. Patients were selected and divided in two groups- typical and atypical celiac disease based upon the presenting symptoms. Upper gastrointestinal endoscopy and duodenal biopsy was performed for serology positive patients. Results were analysed using appropriate statistical test of significance. Out of 101 enrolled patients, 47.5% were male. Age ranged from 1 to 18 years. Study showed that 54.5% were typical and 45.5% were atypical. Patients presenting with atypical symptoms were predominantly of older age group. On endoscopy, scalloping, mosaic pattern, reduced fold height and absent fold height; and in histology, advanced Marsh stage were significantly higher in the typical group. Awareness of atypical presentations as well as duodeno-endoscopic features may have considerable practical importance for the diagnosis of celiac disease in children. Scalloping, mosaic pattern, reduced fold height and nodularity are main endoscopic markers of celiac disease in children. Endoscopic markers of duodenal mucosa may be important in early diagnosis of celiac disease, in children subjected to endoscopy for atypical presentations or indication other than suspected celiac disease.

Nodular gastritis is characterized histologically by hyperplasia and enlargement of lymphoid follicles in the lamina propria. With the objective of elucidating the relationship between different endoscopic types of nodular gastritis and lymphoid follicles, distributions of lymphoid follicles in the lamina propria were investigated in young gastric cancer patients with nodular gastritis. For the study, whole-mucosal step sectioning of each resected stomach was performed, the densities of lymphoid follicles of all specimens were measured microscopically, and the horizontal and depth distributions were calculated. For assessment in the horizontal direction, density distribution diagrams of lymphoid follicles were created. For assessment in the depth direction, the different endoscopic types of nodular gastritis were compared in the five different analysis sites. In the assessment of the horizontal distribution, no characteristic distribution tendencies were observed in either the granular type group or the scattered type group; however, it was found that areas with relatively high densities of lymphoid follicles generally coincided with the areas where nodular gastritis was observed endoscopically. These results suggested that hyperplasia and aggregation of lymphoid follicles in the lamina propria are involved at the sites where nodular gastritis is observed endoscopically. In the assessment of the depth distribution, lymphoid follicles tended to be more unevenly distributed in the upper lamina propria in the granular type group than in the scattered type at the three different analysis sites where nodular gastritis was observed endoscopically. These results suggested the possibility of a granular type characteristic.

Chronic unilateral hematuria (CUH) is also called lateralizing essential hematuria, benign essential hematuria, and benign lateralizing hematuria, which was defined as intermittent or continuous gross hematuria that cannot be diagnosed with standard radiology and hematology studies, together with unilateral bloody efflux by cystoscopy. CUH is rare, but sometimes confused with malignancy or life-threatening hemorrhage. Therefore, it can cause considerable anxiety to not only patients but also urologists. For this study, we summarized articles about endoscopic diagnosis and treatment of CUH, and discussed the development of endourology for CUH. We searched articles related to CUH that were indexed in the PubMed database and published in English. Key terms used were "unilateral," "lateralizing," "chronic," "benign," and "idiopathic" hematuria. We found 15 pertinent articles reporting CUH. Endoscopically, CUH can be classified into three categories: discrete lesion, diffuse lesion, or no (unidentified) lesion. Currently, endoscopic techniques for CUH are similar to the techniques for upper tract urothelial carcinoma, using semi-rigid and flexible ureteroscopes with diathermy fulguration or laser ablation for treatment. The overall success rate of endoscopic treatment for CUH, defined as resolution of gross hematuria after treatment, was 93% (190/205). The recurrence rate, defined as recurrent gross hematuria after treatment, was 10% (19/189). Advancements in endoscopic devices and techniques have enabled more accurate and less invasive diagnosis and treatment of CUH. Once CUH is defined, flexible ureteroscopy is the diagnostic and therapeutic technique of choice.

Cholangioscopy is a useful tool for the study and treatment of biliary pathology. Ultrathin upper endoscopes allow direct peroral cholangioscopy (DPC) but have some drawbacks. The aim of the study was to evaluate the success rate of DPC with an ultrathin endoscope using a balloon catheter to reach the biliary confluence. Prospective observational study. An ultrathin endoscope (Olympus XP180N, outer diameter 5.5 mm, working channel 2 mm) was used. To access the biliary tree, free-hand technique was used. To reach the biliary confluence an intraductal balloon catheter (Olympus B5-2Q diameter 1.9 mm) and a 0.025 inch guide wire was used. In all cases sphincterotomy and/or sphincteroplasty was performed. The success rate was defined as the percentage of cases in which the biliary confluence could be reached with the ultrathin endoscope. Fifteen patients (8 men/7 women) were included. Mean age was 77.7 + or - 10.8 years (range 45-91). The indications for cholangioscopy were suspected bile duct stones (n = 9), electrohydraulic lithotripsy for the treatment of difficult choledocholithiasis (n = 5) and evaluation of biliary stricture (n = 1). Access to the bile duct was achieved in 14/15 cases (93.3%). Biliary confluence was reached in 13/15 cases (86.7%). One complication was observed in one patient (oxigen desaturation). DPC with an ultrathin endoscope can be done with the free-hand technique. Intraductal balloon-guided DPC allows full examination of the common bile duct in most cases.

The aim of this study was to identify the ability of Glasgow-Blatchford score (GBS) and pre-endoscopic Rockall score (pre-E RS) to predict the occurrence of hypotension in patients with non-variceal upper gastrointestinal bleeding who are initially normotensive at emergency department. Retrospective observational study was conducted at Asan Medical Center emergency department (ED) in patients who presented with non-variceal upper gastrointestinal bleeding from January 1, 2011 to December 31, 2013. Study population was divided according to the development of hypotension, and demographics, comorbidities, and laboratory findings were compared. GBS and pre-E RS were estimated to predict the occurrence of hypotension. A total of 747 patients with non-variceal upper gastrointestinal bleeding were included during the study period, and 120 (16.1%) patients developed hypotension within 24 hours after ED admission. The median values GBS and pre-E RS were statistically different according to the occurrence of hypotension (8.0 vs. 10.0, 2.0 vs. 3.0, respectively; p<0.001). In the receiver operating characteristic curve analysis of hypotension development, the area under the curve of GBS and pre-E RS were 66% and 64%, respectively. The sensitivity and the specificity of GBS using optimal cut-off value were 81% and 46%, respectively, while those based on the pre-E RS were 74% and 46%, respectively. GBS and pre-E RS were both not sufficient for predicting the occurrence of hypotension in non-variceal upper gastrointestinal bleeding. Development of other scoring systems are needed.

Gastric carcinoma is a common malignant disease associated with an unfavorable prognosis in the case of late dia-gnosis. The most significant precancerous condition is chronic atrophic gastritis and intestinal metaplasia caused by Helicobacter pylori infection. These longlasting changes may lead to formation of dysplastic precancerous lesions. Upper endoscopy and histologic examination of forceps bio-psy specimens play a key role in the dia-gnosis of gastric precancerous conditions and lesions. Helicobacter pylori eradication therapy and endoscopic surveillance are main therapeutic modalities of gastric precancerous conditions. Localized precancerous lesions and early gastric neoplasia without the risk of lymphatic spread could be cured by means of endoscopic resection techniques.
Development of optical laser balloon and drainage from radiation vulcanized natural rubber latex
NASA Astrophysics Data System (ADS)
Shimamura, Yoshiyuki
Rubber film made of radiation vulcanized natural rubber latex (RVNRL) has better transparency and lower toxicity compared with sulfur-vulcanized latex film. Optical laser balloon (optical endoscopical balloon) and drainage were developed by using RVNRL. An endoscope was equipped with a saline-filled latex rubber balloon at its tip to displace contaminating blood, bile, or gastric contents during operative portoscopy, biliary endoscopy, or upper gastrointestinal endoscopy. The transmission of Nd-Yag laser through the balloon is 98%, higher than the sulfur-vulcanized latex rubber (75%). High transparency of the drainage bag facilitated easy observation of discharged fluids without detaching the bag from the tube.

A case of Fasciola gigantica-induced biliary obstruction and cholestasis is reported in Turkey. The patient was a 37- year-old woman, and suffered from icterus, ascites, and pain in her right upper abdominal region. A total of 7 living adult flukes were recovered during endoscopic retrograde cholangiopancreatography (ERCP). A single dose of triclabendazole was administered to treat possible remaining worms. She was living in a village of southeast of Anatolia region and had sheeps and cows. She had the history of eating lettuce, mallow, dill, and parsley without washing. This is the first case of fascioliasis which was treated via endoscopic biliary extraction during ERCP in Turkey.

This is a companion paper to two previous publications on recommended practices for cleaning and reprocessing flexible endoscopes used in Otolaryngology (Burlingame, Arcilla, & McDermott, 2008; Adams & Baker, 2010). In this paper we capture and expand upon the audience question and answer session in which the Society of Otorhinolaryngology and Head-Neck Nurse (SOHN)--endorsed the Association of periOperative Registered Nurses (AORN) recommended practices were presented to the SOHN membership (Adams & Waddington, September, 2010). We include additional background information to assist readers in understanding some of the science behind the recommendations and share successful implementation strategies from Otorhinolaryngology (ORL) outpatient nurses and published references.

Objective: The aim of this study is to investigate the causes and the strategy of frontal sinusitis after transfrontal craniotomy by endoscopic frontal sinus surgery and traditional surgery with facial incision. Method: A total of thirty-four patients with frontal sinusitis after transfrontal craniotomy were admitted, with the symptom of purulence stuff, headache and upper eyelid discharging. The onset time was 2.6 years on average. The frontal sinus CT and MRI images showed frontal sinusitis. Twenty-seven patients were treated with endoscopic frontal sinus surgery, and seven patient was treated with combined endoscopic and traditional frontal sinus surgery. In the revision surgery, the bone wax and inflammatory granulation tissue were cleaned out in both operational methods. The cure standard was that the postoperative frontal sinus inflammation disappeared and the drainage of the volume recess was unobstructed. Result: Thirty-four patients had a history of transfrontal craniotomy, and there was a record of bone wax packing in every operation. Among twenty-seven patients with endoscopic frontal sinus surgery, Twenty-five cases cured and two cases were operated twice. Seven patients were cured with combined endoscopic and traditional frontal sinus surgery. Conclusion: The frontal sinusitis after transfrontal craniotomy may be related to the inadequate sinus management, especially bone wax to be addressed to the frontal sinus ramming leading to frontal sinus mucosa secretion obstruction and poor drainage. Endoscopic frontal sinus surgery is a way of minimally invasive surgery. The satisfying curative effect can be obtained by endoscopic removal of bone wax, inflammatory granulation tissue, and the enlargement of frontal sinus aperture after exposure to the frontal sinus, and some cases was treated with both operation method.

The optimal management of bleeding peptic ulcer with adherent clot remains controversial. The purpose of this study was to compare clinical outcome between endoscopic therapy and medical therapy. We also evaluated the risk factors of rebleeding in Forrest type IIB peptic ulcer. Upper gastrointestinal (UGI) bleeding registry data from 8 hospitals in Korea between February 2011 and December 2013 were reviewed and categorized according to the Forrest classification. Patients with acute UGI bleeding from peptic ulcer with adherent clots were enrolled. Among a total of 1,101 patients diagnosed with peptic ulcer bleeding, 126 bleedings (11.4%) were classified as Forrest type IIB. Of the 126 patients with adherent clots, 84 (66.7%) received endoscopic therapy and 42 (33.3%) were managed with medical therapy alone. The baseline characteristics of patients in two groups were similar except for higher Glasgow Blatchford Score and pre-endoscopic Rockall score in medical therapy group. Bleeding related mortality (1.2% vs.10%; p=0.018) and all cause mortality (3.7% vs. 20.0%; p=0.005) were significantly lower in the endoscopic therapy group. However, there was no difference between endoscopic therapy and medical therapy regarding rebleeding (7.1% vs. 9.5%; p=0.641). In multivariate analysis, independent risk factors of rebleeding were previous medication with aspirin and/or NSAID (OR, 13.1; p=0.025). In patients with Forrest type IIB peptic ulcer bleeding, endoscopic therapy was associated with a significant reduction in bleeding related mortality and all cause mortality compared with medical therapy alone. Important risk factor of rebleeding was use of aspirin and/or NSAID.

To obtain prospective outcomes data on patients (pts) undergoing palliative operative or endoscopic procedures for malignant bowel obstruction due to recurrent ovarian cancer. An institutional study was conducted from July 2002 to July 2003 to prospectively identify pts who underwent an operative or endoscopic procedure to palliate the symptoms of advanced cancer. This report focuses on pts with malignant bowel obstruction due to recurrent ovarian cancer. Procedures performed with an upper or lower gastrointestinal (GI) endoscope were considered "endoscopic." All other cases were classified as "operative." Following the procedure, the presence or absence of symptoms was determined and followed over time. All pts were followed until death. Palliative interventions were performed on 74 gynecologic oncology pts during the study period, of which 26 (35%) were for malignant GI obstruction due to recurrent ovarian cancer. The site of obstruction was small bowel in 14 (54%) cases and large bowel in 12 (46%) cases. Palliative procedures were operative in 14 (54%) pts and endoscopic in the other 12 (46%). Overall, symptomatic improvement or resolution within 30 days was achieved in 23 (88%) of 26 patients, with 1 (4%) postprocedure mortality. At 60 days, 10 (71%) of 14 pts who underwent operative procedures and 6 (50%) of 12 pts who had endoscopic procedures had symptom control. Median survival from the time of the palliative procedure was 191 days (range, 33-902) for those undergoing an operative procedure and 78 days (range, 18-284) for those undergoing an endoscopic procedure. Patients with malignant bowel obstructions due to recurrent ovarian cancer have a high likelihood of experiencing relief of symptoms with palliative procedures. Although recurrence of symptoms is common, durable palliation and extended survival are possible, especially in those patients selected for operative intervention.
[TITANIUM NICKELIDE TECHNOLOGIES IN MINIMALLY INVASIVE SURGERY OF KIDNEY AND UPPER URINARY TRACT].
Feofilov, L V
2015-01-01
The most common pathology of the kidney and upper urinary tract includes nephrolithiasis, ureteral strictures and renal cysts. In the treatment of patients with these diseases, the majority of surgeons prefer minimally invasive techniques, including endoscopic surgery. The complication rate of percutaneous surgery is a major factor in encouraging the search for new treatments. We have analyzed the results of 402 x-ray-endoscopic operations performed with the use of technologies based on titanium nickelide materials in patients with nephrolithiasis, ureteral strictures and kidney cysts. The high effectiveness and reliability of porous titanium nickelide cryoapplicator was noted in control of percutaneous channel bleeding and prevention. The proposed suspension nephropexy with fine titanium granules in coexisting nephrolithiasis and nephroptosis demonstrated 1.5 times greater effectiveness compared to the traditional nephropexy, reducing duration of nephrostomy and rehabilitation by almost 3 times. The proposed methods of intubation by permanent and temporary stents with shape memory after percutaneous ureteropelvic junction stricture correction are promising in the treatment of patients with this pathology of the upper urinary tract. Application of titanium nickelide implants in simple renal cyst surgery has led to a significant increase in the effectiveness of these operations, improvement in long-term results and patients' quality of life.

The goal of this study was to retrospectively assess the efficacy of emergency percutaneous transcatheter arterial embolization in patients with severe bleeding due to upper gastrointestinal or jejunal tumor. Twelve patients (7 men, 5 women; mean age, 74 years±14 (SD); range: 54-86 years) with severe bleeding from the upper gastrointestinal tract, with failed endoscopic treatment not eligible for emergency surgery were treated by emergency percutaneous transcatheter arterial embolization. The bleeding cause was gastric tumor in 7 patients, duodenal tumor in 4 patients and jejunal tumor in one patient. Procedure details and follow-up were reviewed. Twelve embolization procedures were performed using various embolic agents. Embolization was achieved and bleeding was stopped in all patients. Five patients underwent surgery within the 30 days following embolization. In the remaining 7 patients, no bleeding occurred at 1 month follow-up in 6 patients and bleeding recurred in one patient at 1 month. In this later patient, endoscopic treatment was successful. The results of our study suggest that transcatheter arterial embolization is safe and effective in patients with severe arterial bleeding due to upper gastrointestinal or jejunal tumor. In some patients, transcatheter arterial embolization can be used as a bridge to surgery. Copyright © 2016 Éditions françaises de radiologie. Published by Elsevier Masson SAS. All rights reserved.

The aim was to assess the incidence of endoscopic findings based on the indication of the procedures in upper/lower endoscopies, and measuring quality indicators of colonoscopies at the 1st Department of Medicine, Semmelweis University, Budapest. Data of 2987 patients (male/female:1361/1626, mean age: 60.7 years(y), SD: 16.7y) between 01.01.2010 and 31.12.2011 were analyzed. Both inpatient and outpatient records were collected. Incidence of peptic ulcer disease, esophageal varices, gastric polyps and gastric cancer were 10.8%, 4.5%, 6.1%, 2.9% in upper endoscopies, respectively. In colonoscopies colorectal polyps, diverticulosis, colorectal cancer and IBD were found in 29.9%, 22.4%, 6.9%, 9.7%, respectively. In patients having upper endoscopy with GI bleeding indication, older age (p<0.001), male gender (p<0.001, OR: 1.64), acenocoumarol/heparin use (p<0,001, peptic ulcers and esophageal varices were more frequent (p<0.001, OR: 2.83 and p<0.001, OR: 2.79), while in colonoscopies colorectal cancer had higher incidence (p<0.001, OR:3.27). 81% of colonoscopies were complete. Causes of incomplete procedures were ineffective bowel preparation (38.2%), technical difficulties (25.1%) and strictures (20.5%). The endoscopic findings and quality indicators (adenoma detection rate, coecal intubation rate) were in line with that reported in published series. Orv. Hetil., 2016, 157(52), 2074-2081.

Retrograde gastroesophageal intussusception (RGEI) is a relatively rare gastrointestinal (GI) disorder in which a portion of the stomach wall invaginates into the esophagus. More recently, peroral endoscopic myotomy (POEM) has emerged as an endoscopic alternative to surgical myotomy for achalasia, and, to the best of our knowledge, our case is the first RGEI after POEM to be reported. A 22-year-old male was presented with a history of vomiting, intractable retching and hematemesis for 3 days. He had a history of achalasia and underwent POEM 3 years ago caused by symptoms of severe dysphagia to solid and liquid. Initially, the patient was diagnosed with a blood-filled esophagus, and the mid esophagus was occluded with a ball-like mass, however, the final diagnosis of RGEI was made by thoracotomy. A therapeutic strategy of conservative treatment and left transthoracic surgery were applied. The surgery and post operative course were uneventful, and he remained asymptomatic 1 year after operation. POEM is a reliable and minimally invasive endoscopic method for esophageal achalasia. Early recognition and severity of RGEI are essential to decrease the unwanted complications. Upper GI series, esophagogastroduodenoscopy and computed tomography scan are helpful for diagnostic purposes of RGEI. Conservative treatment, endoscopic intervention, and surgery are the mainstay of treatments for RGEI. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

Monthly sampling of shovelnose sturgeon Scaphirhynchus platorynchus, a biological surrogate for the endangered pallid sturgeon Scaphirhynchus albus, was conducted to develop a multiseasonal profile of reproductive stages. Data collected included histological characteristics of gonads from wild caught fish and laboratory and field ultrasonic and endoscopic images. These data were used to compare effectiveness of ultrasonic and endoscopic techniques at identifying gender of adult shovelnose sturgeon at different reproductive stages. The least invasive method (i.e. ultrasound) was least effective while the most invasive (i.e. endoscope through an abdominal incision) was the most effective at identifying shovelnose sturgeon gender. In most cases, success rate for identifying males was greater than females, with success at identifying both genders greater in more advanced reproductive stages. Concomitantly, for most months average reproductive stage was more advanced for males than females. April and May were the months with the most advanced reproductive stage, and were the months when ultrasound was most effective. Methods were also applied in the Upper Missouri River to validate their use on pallid sturgeon Scaphirhynchus albus. Ultrasound was successful at identifying pallid sturgeon gender, however, endoscopic examination through the urogenital duct was only successful at identifying pallid sturgeon gender when the urogenital duct was not opaque. ?? 2005 The Fisheries Society of the British Isles.

Ectopic variceal bleeding is a rare (2-5%) but fatal gastrointestinal bleed in patients with portal hypertension. Patients with ectopic variceal bleeding manifest melena, hematochezia, or hematemesis, which require urgent managements. Definitive therapeutic modalities of ectopic varices are not yet standardized because of low incidence. Various therapeutic modalities have been applied on the basis of the experiences of experts or availability of facilities, with varying results. We have encountered eight cases of gastrointestinal ectopic variceal bleeding in five patients in the last five years. All patients were diagnosed with liver cirrhosis presenting melena or hematemesis. All patients were treated with various endoscopic modalities (endoscopic variceal obturation [EVO] with cyanoacrylate in five cases, endoscopic variceal band ligation (EVL) in two cases, hemoclipping in one case). Satisfactory hemostasis was achieved without radiologic interventions in all cases. EVO and EVL each caused one case of portal biliopathy, and EVL induced ulcer bleeding in one case. EVO generally accomplished better results of variceal obturations than EVL or hemoclipping, without serious adverse events. EVO may be an effective modality for control of ectopic variceal bleeding without radiologic intervention or surgery.

Dysphagia is a common problem and an indication for upper endoscopy. There is no data on the frequency of the different endoscopic findings and whether they change according to demographics or by single versus repeat endoscopy. To determine the prevalence of endoscopic findings in patients with dysphagia and whether findings differ in regard to age, gender, ethnicity, and repeat procedure. This was a retrospective study using a national endoscopic database (CORI). A total of 30,377 patients underwent esophagogastroduodenoscopy (EGD) for dysphagia of which 4,202 patients were repeat endoscopies. Overall frequency of endoscopic findings was determined by gender, age, ethnicity, and single vs. repeat procedures. Esophageal stricture was the most common finding followed by normal, esophagitis/ulcer (EU), Schatzki ring (SR), esophageal food impaction (EFI), and suspected malignancy. Males were more likely to undergo repeat endoscopies and more likely to have stricture, EU, EFI, and suspected malignancy (P = 0.001). Patients 60 years or older had a higher prevalence of stricture, EU, SR, and suspected malignancy (P < 0.0001). Esophageal stricture was most common in white non-Hispanic patients compared to other ethnic groups. In patients undergoing repeat EGD, stricture, SR, EFI, and suspected malignancy were more common (P < 0.0001). The prevalence of endoscopic findings differs significantly by gender, age, and repeat procedure. The most common findings in descending order were stricture, normal, EU, SR, EFI, and suspected malignancy. For patients undergoing a repeat procedure, normal and EU were less common and all other abnormal findings were significantly more common.

In the present study, clips were used as markers to evaluate displacement differences between proximal and distal ends of esophageal tumors and to test whether their internal target volume (ITV) margins should be determined separately. A total of 23 patients with mid-upper thoracic esophageal squamous-cell carcinoma, a tumor length of ≤8 cm and an esophageal lumen suitable for endoscopic ultrasonography were recruited for the present study. Clips were implanted endoscopically at the proximal and distal ends of the esophageal tumor (upper and lower clips). In a further exploratory study on 16 of the patients, a third clip was placed at the distal esophagus 2 cm above the gastro-esophageal junction (GEJ) (cardiac clip). The clips were contoured for all 10 phases of the four-dimensional computed tomography and the maximum displacements of the clip centroids among different breathing phases in left-right (LR), superior-inferior (SI) and anterior-posterior (AP) directions were marked as x, y and z, respectively. The ITV margins that covered 95% of the LR, SI and AP motion were 2.89, 5.00 and 2.36 mm, respectively. Axial displacement (y) was greater than radial displacement (x, z; P<0.05). It was also revealed that LR(x), SI(y) and AP(z) displacement of cardiac clips was greater than that of upper or lower clips (P<0.05). Differences in the axial and radial displacement of the upper and lower clips indicated that axial and radial ITV margins should be determined separately. However, further study is required on patients in whom the distal tumor end is located in proximity to the GEJ.

Background Patients with malignant tumours of the upper gastrointestinal tract tumours exhibit important alarm symptoms such as dysphagia that warrant clinical investigations. An endoscopic examination of the upper gastrointestinal tract will be required in most cases. This study evaluates the diagnostic potential of index endoscopy in a random population of patients with dysphagia. Methods This is a retrospective analysis of prospectively collected data over 10 years. Patients with previous endoscopic evaluation or upper gastrointestinal pathology were excluded from the study. Data was analysed to see the number and frequency of abnormal findings in upper gastrointestinal tract, and their significance in relation to the presenting symptoms. Results Total number of index endoscopies was 13, 881. 913 patients were included in the study including 465 males (age range: 17–92 years, median: 55 years) and 448 females (age range: 18–100, median: 59 years), with male to female ratio of 1.04: 1. Oesophagus was abnormal in 678 cases (74%) and biopsies were taken in 428 patients (47%). Superficial oesophagitis, Barrett's oesophagus, oesophageal cancer, and oesophageal ulcer were main histological findings. Age more than 50 years and weight loss were significant predictors of oesophageal cancer (p < 0.0001). Male gender, heartburn, epigastric pain, weight loss and vomiting were significantly related to Barrett's oesophagus. A total of 486 gastric and 56 duodenal biopsies were also taken. There were 20 cases of gastric adenocarcinoma. Conclusion OGD is an effective initial investigation to assess patients with dysphagia, especially males above the age of 50 years. Patients may be started on treatment or referred for further investigations, for example, a barium meal in the absence of any anatomical abnormality. PMID:18034883

Inappropriateness of upper endoscopy (EGD) indication causes decreased diagnostic yield. Our aim of was to identify predictors of appropriateness rate for EGD among endoscopic centres. A post-hoc analysis of two multicentre cross-sectional studies, including 6270 and 8252 patients consecutively referred to EGD in 44 (group A) and 55 (group B) endoscopic Italian centres in 2003 and 2007, respectively, was performed. A multiple forward stepwise regression was applied to group A, and independently validated in group B. A <70% threshold was adopted to define inadequate appropriateness rate clustered by centre. discrete variability of clustered appropriateness rates among the 44 group A centres was observed (median: 77%; range: 41-97%), and a <70% appropriateness rate was detected in 11 (25%). Independent predictors of centre appropriateness rate were: percentage of patients referred by general practitioners (GP), rate of urgent examinations, prevalence of relevant diseases, and academic status. For group B, sensitivity, specificity and area under receiver operating characteristic curve of the model in detecting centres with a <70% appropriateness rate were 54%, 93% and 0.72, respectively. A simple predictive rule, based on rate of patients referred by GPs, rate of urgent examinations, prevalence of relevant diseases and academic status, identified a small subset of centres characterised by a high rate of inappropriateness. These centres may be presumed to obtain the largest benefit from targeted educational programs. Copyright (c) 2010 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

In the recent study delta-aminolevulinic acid/Protoporphyrin IX (5-ALA/PpIX) is used as fluorescent marker for dysplasia and tumor detection in esophagus and stomach. The 5-ALA is administered per os six hours before measurements at dose 20mg/kg weight. High-power light-emitting diode at 405 nm is used as an excitation source. Special opto-mechanical device is built for LED to use the light guide of standard video-endoscopic system (Olimpus Corp.). Through endoscopic instrumental channel a fiber is applied to return information about fluorescence to microspectrometer (USB4000, OceanOptics Inc.). Very good correlation between fluorescence signals and histology examination of the lesions investigated is achieved.

Confocal LASER endomicroscopy (CLE) is a new endoscopic technique which allows subsurface in vivo microscopic analysis during ongoing endoscopy, using systemically or topically administered fluorescent agents. It allows targeted biopsies to be taken, potentially improving the diagnostic rate in certain gastrointestinal diseases. Worldwide experience with CLE for upper gastrointestinal malignant and premalignant lesions is still reduced. Potential clinical applications are presented, including diagnosis of NERD, Barrett's esophagus, atrophic gatritis, gastric intestinal metaplasia and dysplasia, gastric adenomatous or hyperplastic polyps, gastric cancer.

Vascular ectasias, including gastric antral vascular ectasia (GAVE) and angiodysplasia, are increasingly recognized as important sources of gastrointestinal bleeding. This study investigated and compared the efficacies and outcomes of treatment of upper gastrointestinal (UGI) angiodysplasia and GAVE hemorrhage by endoscopic argon plasma coagulation (APC). From January 2006 to December 2009, 46 patients diagnosed with upper GI bleeding caused by angiodysplasia or GAVE at a tertiary hospital were recruited into this study. They included 26 males and 20 females with an average age of 65.6 years (range, 45-90 years). All patients underwent APC for hemostasis during an endoscopic procedure. Parameters such as underlying co-morbidities, number of endoscopic treatment sessions, recurrent bleeding, and clinical outcomes during follow-up were analyzed. The 46 patients with UGI vascular ectasia hemorrhage included 27 patients with angiodysplasia and 19 with GAVE. The patients with angiodysplasia were older than those with GAVE (71.6 ± 10.2 years versus 61.8 ± 11.9 years, P = 0.005). More GAVE patients than angiodysplasia patients had co-existing liver cirrhosis (63.2% versus 25.9%, P = 0.012). The patients with GAVE had a higher rate of recurrent bleeding (78.9% versus 7.4%, P < 0.001) and required more treatment sessions to achieve complete hemostasis (2.4 ± 1.4 versus 1.1 ± 0.1, P < 0.001) than those with angiodysplasia. Univariate analysis demonstrated that age greater than 60 years (odds ratio (OR) = 8.929, P = 0.003), GAVE (OR = 0.021, P < 0.001), and previous radiation therapy (OR = 11.667, P = 0.032) were associated with higher rates of recurrent bleeding. Further multivariate analysis revealed that GAVE was the only independent risk factor for recurrent bleeding after APC treatment (OR = 0.027, P < 0.001). Endoscopic hemostasis with APC is a safe treatment modality for both angiodysplasia and vascular ectasia bleeding. The efficacy of APC treatment is greater for angiodysplasia than for vascular ectasia bleeding. GAVE patients have a higher recurrent bleeding rate and may require multiple treatment sessions for sustained hemostasis.

Carpal tunnel release is the most common upper-limb surgical procedure performed annually in the U.S. There are 2 surgical methods of carpal tunnel release: open or endoscopic. Currently, there is no clear clinical or economic evidence supporting the use of one procedure over the other. We completed a cost-minimization analysis of open and endoscopic carpal tunnel release, testing the null hypothesis that there is no difference between the procedures in terms of cost. We conducted a retrospective review using a private-payer and Medicare Advantage database composed of 16 million patient records from 2007 to 2014. The cohort consisted of records with an ICD-9 (International Classification of Diseases, Ninth Revision) diagnosis of carpal tunnel syndrome and a CPT (Current Procedural Terminology) code for carpal tunnel release. Payer fees were used to define cost. We also assessed other associated costs of care, including those of electrodiagnostic studies and occupational therapy. Bivariate comparisons were performed using the chi-square test and the Student t test. Data showed that 86% of the patients underwent open carpal tunnel release. Reimbursement fees for endoscopic release were significantly higher than for open release. Facility fees were responsible for most of the difference between the procedures in reimbursement: facility fees averaged $1,884 for endoscopic release compared with $1,080 for open release (p < 0.0001). Endoscopic release also demonstrated significantly higher physician fees than open release (an average of $555 compared with $428; p < 0.0001). Occupational therapy fees associated with endoscopic release were less than those associated with open release (an average of $237 per session compared with $272; p = 0.07). The total average annual reimbursement per patient for endoscopic release (facility, surgeon, and occupational therapy fees) was significantly higher than for open release ($2,602 compared with $1,751; p < 0.0001). Our data showed that the total average fees per patient for endoscopic release were significantly higher than those for open release, although there currently is no strong evidence supporting better clinical outcomes of either technique. Value-based health-care models that favor delivering high-quality care and improving patient health, while also minimizing costs, may favor open carpal tunnel release.
Focal achalasia – case report and review of the literature
TUTUIAN, RADU
2018-01-01
Esophageal achalasia is a primary smooth muscle motility disorder specified by aperistalsis of the tubular esophagus in combination with a poorly relaxing and occasionally hypertensive lower esophageal sphincter (LES). These changes occur secondary to the destruction of the neural network coordinating esophageal peristalsis and LES relaxation (plexus myentericus). There are limited data on segmental involvement of the esophagus in adults. We report on the case of a 54-year-old man who presented initially with complete aperistalsis limited to the distal esophagus. After a primary good response to BoTox-infiltration of the distal esophagus the patient relapsed two years later. The manometric recordings documented now a progression of the disease with a poorly relaxing hypertensive lower esophageal sphincter and complete aperistalsis of the tubular esophagus (type III achalasia according to the Chicago 3.0 classification system). This paper also reviews diagnostic findings (including high resolution manometry, CT scan, barium esophagram, upper endoscopy and upper endoscopic ultrasound data) in patients with achalasia and summarizes the therapeutic options (including pneumatic balloon dilatation, botulinum toxin injection, surgical or endoscopic myotomy).

We have studied 80 patients with pernicious anaemia. Upper gastrointestinal endoscopy (with biopsy and cytology) showed no lesion other than atrophic gastritis in 34 patients. Thirty three patients, however, had varying degrees of gastric mucosal dysplasia, which was detected more frequently by histology than by cytology. The endoscopic appearance of the mucosa was abnormal in four of the six patients with moderate dysplasia, and in all three patients with severe dysplasia. One patient was found to have a small carcinoma in the gastric antrum, and underwent total gastrectomy; 18 patients had polyps (often multiple); four of these were treated by endoscopic polypectomy. One of the patients with polyps had multiple carcinoid tumours, and an asymptomatic parathyroid adenoma. Seventeen of the patients also underwent barium meal examination; abnormalities were revealed in only three of the seven patients with lesions visible at endoscopy. Our results justify further endoscopic studies in patients with pernicious anaemia, and sequential examinations to establish the natural history of gastric dysplasia.

Epidemiology, Diagnosis, and Management of Esophageal Adenocarcinoma
Rubenstein, Joel H.; Shaheen, Nicholas J.
2015-01-01
Esophageal adenocarcinoma (EAC) is rapidly increasing in incidence in Western cultures. Barrett’s esophagus (BE) is the presumed precursor lesion for this cancer. Several other risk factors for this cancer have been described, including chronic heartburn, tobacco use, Caucasian race, and obesity. Despite these known associations, most patients with EAC present with symptoms of dysphagia from late-stage tumors—only a small minority of patients are identified in screening and surveillance programs. Diagnostic analysis of EAC usually commences with upper endoscopy, followed by cross-sectional imaging. Endoscopic ultrasound is useful to assess local extent of disease as well as the involvement regional lymph nodes. T1a EAC may be treated endoscopically; some patients with T1b disease might also benefit from endoscopic therapy. Locally advanced disease is generally managed with esophagectomy, often accompanied by neoadjuvant chemoradiotherapy or chemotherapy. The prognosis is based on tumor stage: patients with T1a tumors have an excellent prognoses, whereas few patients with advanced disease have longterm survival. PMID:25957861
Diagnosis and management of upper gastrointestinal bleeding in children.
Owensby, Susan; Taylor, Kellee; Wilkins, Thad
2015-01-01
Upper gastrointestinal bleeding is an uncommon but potentially serious, life-threatening condition in children. Rapid assessment, stabilization, and resuscitation should precede all diagnostic modalities in unstable children. The diagnostic approach includes history, examination, laboratory evaluation, endoscopic procedures, and imaging studies. The clinician needs to determine carefully whether any blood or possible blood reported by a child or adult represents true upper gastrointestinal bleeding because most children with true upper gastrointestinal bleeding require admission to a pediatric intensive care unit. After the diagnosis is established, the physician should start a proton pump inhibitor or histamine 2 receptor antagonist in children with upper gastrointestinal bleeding. Consideration should also be given to the initiation of vasoactive drugs in all children in whom variceal bleeding is suspected. An endoscopy should be performed once the child is hemodynamically stable. © Copyright 2015 by the American Board of Family Medicine.

Failure of proton pump inhibitor (PPI) treatment in patients with heartburn is very common. Because endoscopy is easily accessible, it is commonly used as the first evaluative tool in these patients. To compare GERD-related endoscopic and histologic findings in patients with heartburn in whom once-daily PPI therapy failed versus those not receiving antireflux treatment. Cross-sectional study. A Veterans Affairs hospital. Heartburn patients from the GI outpatient clinic. Recording of endoscopic results. Endoscopic findings and association between PPI treatment failure and esophageal mucosal injury by using logistic regression models. A total of 105 subjects (mean age 54.7 +/- 15.7 years; 71 men, 34 women) were enrolled in the PPI treatment failure group and 91 (mean age 53.4 +/- 15.8 years; 68 men, 23 women) were enrolled in the no-treatment group (P = not significant). Anatomic findings during upper endoscopy were significantly more common in the no-treatment group compared with the PPI treatment failure group (55.2% vs 40.7%, respectively; P = .04). GERD-related findings were significantly more common in the no-treatment group compared with the PPI treatment failure group (erosive esophagitis: 30.8% vs 6.7%, respectively; P < .05). Eosinophilic esophagitis was found in only 0.9% of PPI treatment failure patients. PPI treatment failure was associated with a significantly decreased odds ratio of erosive esophagitis compared with no treatment, adjusted for age, sex, and body mass index (adjusted odds ratio 0.11; 95% CI, 0.04-0.30). Heartburn patients in whom once-daily PPI treatment failed demonstrated a paucity of GERD-related findings compared with those receiving no treatment. Eosinophilic esophagitis was uncommon in PPI therapy failure patients. Upper endoscopy seems to have a very low diagnostic yield in this patient population. 2010 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc. All rights reserved.
[Differentiation therapy for non-acidic gastroesophageal reflux disease].

2017-01-01
To investigate the clinical and pathogenetic features of the non-acidic types of gastroesophageal reflux disease (GERD) and to evaluate the impact of combined therapy versus monotherapy on the course of this disease. The investigation enrolled 62 patients with non-acidic GERD. The follow-up period was 6 weeks. The patients were divided into 2 groups: 1) weakly acidic gastroesophageal refluxes (GER); 2) weakly alkaline GER. Then each group was distributed, thus making up 4 groups: 1) 19 patients with weakly acidic GER who received monotherapy with rabeprazole 20 mg/day; 2) 21 patients with weakly acidic GER had combined therapy with rabeprazole 20 mg and itopride; 3) 8 patients with weakly alkaline GER who received ursodeoxycholic acid (UDCA) monotherapy; and 4) 14 patients with weakly alkaline GER who had combined therapy with UDCA and itopride, The clinical symptoms of the disease, the endoscopic pattern of the upper gastrointestinal tract (GIT) mucosa, histological changes in the esophageal and gastric mucosa, and the results of 24-hour impedance pH monitoring were assessed over time. During differentiation therapy, the majority of patients reported positive clinical changes and an improved or unchanged endoscopic pattern. Assessment of impedance pH monitoring results revealed decreases in the overall number of GERs, the presence of a bolus in the esophagus, and the number of proximal refluxes. These changes were noted not only in patients taking proton pump inhibitors (PPIs), but also in those treated with UDCA monotherapy or combined PPI and prokinetic therapy. A differentiated approach to non-acidic GER treatment contributes to its efficiency. Adding the prokinetic itomed (itopride hydrochloride) to PPI therapy in a patient with weakly acidic GER enhances the efficiency of treatment, by positively affecting upper GIT motility. The mainstay of therapy for GERD with a predominance of weakly alkaline refluxes is UDCA, the combination of the latter and the prokinetic can exert a more pronounced effect on the clinical and endoscopic pattern and upper GIT motility.
ACG Clinical Guideline: Management of Patients With Acute Lower Gastrointestinal Bleeding.
Strate, Lisa L; Gralnek, Ian M
2016-04-01
This guideline provides recommendations for the management of patients with acute overt lower gastrointestinal bleeding. Hemodynamic status should be initially assessed with intravascular volume resuscitation started as needed. Risk stratification based on clinical parameters should be performed to help distinguish patients at high- and low-risk of adverse outcomes. Hematochezia associated with hemodynamic instability may be indicative of an upper gastrointestinal (GI) bleeding source and thus warrants an upper endoscopy. In the majority of patients, colonoscopy should be the initial diagnostic procedure and should be performed within 24 h of patient presentation after adequate colon preparation. Endoscopic hemostasis therapy should be provided to patients with high-risk endoscopic stigmata of bleeding including active bleeding, non-bleeding visible vessel, or adherent clot. The endoscopic hemostasis modality used (mechanical, thermal, injection, or combination) is most often guided by the etiology of bleeding, access to the bleeding site, and endoscopist experience with the various hemostasis modalities. Repeat colonoscopy, with endoscopic hemostasis performed if indicated, should be considered for patients with evidence of recurrent bleeding. Radiographic interventions (tagged red blood cell scintigraphy, computed tomographic angiography, and angiography) should be considered in high-risk patients with ongoing bleeding who do not respond adequately to resuscitation and who are unlikely to tolerate bowel preparation and colonoscopy. Strategies to prevent recurrent bleeding should be considered. Nonsteroidal anti-inflammatory drug use should be avoided in patients with a history of acute lower GI bleeding, particularly if secondary to diverticulosis or angioectasia. Patients with established high-risk cardiovascular disease should not stop aspirin therapy (secondary prophylaxis) in the setting of lower GI bleeding. [corrected]. The exact timing depends on the severity of bleeding, perceived adequacy of hemostasis, and the risk of a thromboembolic event. Surgery for the prevention of recurrent lower gastrointestinal bleeding should be individualized, and the source of bleeding should be carefully localized before resection.

The clinical importance of Crohn's disease (CD)-specific lesions in the upper gastrointestinal tract (upper GIT) has not been sufficiently established. The aim of this case-control study is to investigate the characteristic findings of CD in the upper GIT. In 2740 patients who underwent gastroduodenoscopy at Asahikawa Medical University between April 2011 and December 2012, 81 CD patients, 81 gender- and age-matched non-IBD patients, and 66 ulcerative colitis (UC) patients were investigated in the present study. (1) The diagnostic ability and odds ratio of each endoscopic finding (a bamboo joint-like appearance in the cardia, erosions, and/or ulcers in the antrum, notched signs, and erosions and/or ulcers in the duodenum) were compared between the CD and non-IBD patients or UC patients. (2) The interobserver agreement of the diagnosis based on the endoscopic findings was evaluated by 3 experienced and 3 less-experienced endoscopists. The incidence of detecting a bamboo joint-like appearance, notched signs, and erosions and/or ulcers in the duodenum was significantly higher in the CD patients than in the non-IBD and UC patients. In addition, the diagnostic ability and odds ratio of a bamboo joint-like appearance for CD were higher than those for the other findings. Kendall's coefficients of concordance in the group of experienced and less-experienced endoscopists were relatively high for a bamboo joint-like appearance (0.748 and 0.692, respectively). A cardiac bamboo joint-like appearance is a useful finding for identifying high-risk groups of CD patients using only gastroduodenoscopy.

Upper gastrointestinal bleeding (UGIB) is a severe and life-threatening complication among patients with portal hypertension (PH). Covered transjugular intrahepatic portosystemic shunt (TIPS) is the treatment of choice for patients with refractory or recurrent UGIB despite pharmacological and endoscopic therapy. In some patients, TIPS implantation is not possible due to co-morbidity or vascular disorders. Spleen embolization (SE) may be a promising alternative in this setting. We retrospectively analyzed 9 patients with PH-induced UGIB who underwent partial SE between 2012 and 2016. All patients met the following criteria: (i) upper gastrointestinal hemorrhage with primary or secondary failure of endoscopic interventions and (ii) TIPS implantation not possible. Each patient was followed for at least 6 months after embolization. Five patients (56%) suffered from cirrhotic PH, 4 patients (44%) from non-cirrhotic PH. UGIB occured in terms of refractory hemorrhage from gastric varices (3/9; 33%), hemorrhage from esophageal varices (3/9; 33%), and finally, hemorrhage from portal-hypertensive gastropathy (3/9; 33%). None of the patients treated with partial SE experienced re-bleeding episodes or required blood transfusions during a total follow-up time of 159 months, including both patients with cirrhotic- and non-cirrhotic PH. Partial SE, as a minimally invasive intervention with low procedure-associated complications, may be a valuable alternative for patients with recurrent PH-induced UGIB refractory to standard therapy.

Topical therapy (TT) for upper tract urothelial carcinoma (UTUC) has been explored as a kidney sparing approach to treat carcinoma in situ (CIS) and as adjuvant for endoscopically treated Ta/T1 tumors. In bladder cancer, data support use of salvage TT for repeat induction. We investigate the outcomes of salvage TT for UTUC in patients ineligible for or refusing nephroureterectomy. A single-center retrospective review on patients receiving salvage TT via percutaneous nephrostomy tube or cystoscopically placed ureteral catheters was performed. Primary outcome was response to therapy based on International Bladder Cancer Group criteria. 51 patients with 58 renal units (RUs) received TT. Of these, 17 patients with 18 RUs received the second-line TT, with a median follow-up of 36.5 months (IQR 24.5-67 months). 44% (8/18) received salvage TT for refractory disease and 56% (10/18) as reinduction. 5 RUs with CIS were unresponsive to initial TT and went on to receive salvage TT, of which 20% (1/5) responded. 13 RUs recurred or relapsed following initial TT and received salvage TT for papillary tumors, with 62% (8/13) responding. Our data provide preliminary clinical rationale for the second-line TT for refractory and recurrent, endoscopically managed papillary UTUC in patients ineligible for or refusing nephroureterectomy. However, refractory upper tract CIS appears to have poor response to salvage TT.

The conservative management of upper tract urothelial carcinoma (UTUC) has historically been offered to patients with imperative indications. The recent International Consultation on Urologic Diseases (ICUD) publication on UTUC stratified treatment allocations based on high- and low-risk groups. This report updates the conservative management of the low-risk group. The ICUD for low-risk UTUC working group performed a thorough review of the literature with an assessment of the level of evidence and grade of recommendation for a variety of published studies in this disease space. We update these publications and provide a summary of that original report. There are no prospective randomized controlled studies to support surgical management guidelines. A risk-stratified approach based on clinical, endoscopic, and biopsy assessment allows selection of patients who could benefit from kidney-preserving procedures with oncological outcomes potentially similar to radical nephroureterectomy with bladder cuff excision, with the added benefit of renal function preservation. These treatments are aided by the development of high-definition flexible digital URS, multi-biopsies with the aid of access sheaths and other tools, and promising developments in the use of adjuvant topical therapy. Recent developments in imaging, minimally invasive techniques, multimodality approaches, and adjuvant topical regimens and bladder cancer prevention raise the hope for improved risk stratification and may greatly improve the endoscopic treatment for low-risk UTUC.

Gastric bezoars are a rare condition associated with situations of gastric dysmotility and prior gastric surgery, though sometimes they can present without any risk factor. We describe the first successful treatment in medical literature of a large gastric bezoar in the outpatient setting through endoscopic fragmentation. A 76-year-old man was referred to our outpatient endoscopy clinic because of dyspepsia and epigastric pain. Upper GI endoscopy with a standard endoscope revealed a 10-cm-diameter gastric phytobezoar with necrotic pressure ulcer of the angulus. We fragmentized the bezoar into smaller pieces, with complete dissolution and without any complication. The patient was then promptly discharged home with a medical therapy. Follow-up endoscopy at 6 months showed the total disappearance of any residual fibers. Different types of bezoars are described in literature, of which phyto- and trychobezoars are the most frequent. They can be absolutely asymptomatic or can arise with epigastric pain, pressure ulcer bleeding, gastrointestinal perforation or small bowel obstruction. The treatment is debated though endoscopic removal or fragmentation with the help of Coca-Cola lavages has showed the best success rate. The main experiences in literature concern hospitalized patients or describe treatment techniques which require overnight stays. An effective and rapid treatment in the outpatient setting is described in our experience, without short- or long-term complications. The endoscopic fragmentation of large gastric bezoars in the outpatient setting is safe with a good clinical course. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Background Sampling of submucosal lesions in the gastrointestinal tract through a flexible endoscope is a well-recognized clinical problem. One technique often used is endoscopic ultrasound-guided fine-needle aspiration, but it does not provide solid tissue biopsies with preserved architecture for histopathological evaluation. To obtain solid tissue biopsies from submucosal lesions, we have constructed a new endoscopic biopsy tool and compared it in a crossover study with the standard double cupped forceps. Methods Ten patients with endoscopically verified submucosal lesions were sampled. The endoscopist selected the position for the biopsies and used the instrument selected by randomization. After a biopsy was harvested, the endoscopist chose the next site for a biopsy and again used the instrument picked by randomization. A total of 6 biopsies, 3 with the forceps and 3 with the drill instrument, were collected in every patient. Results The drill instrument resulted in larger total size biopsies (mm 2 ; Mann-Whitney U test, P = .048) and larger submucosal part (%) of the biopsies (Mann-Whitney U test, P = .003) than the forceps. Two patients were observed because of chest pain and suspicion of bleeding in 24 hours. No therapeutic measures were necessary to be taken. Conclusion The new drill instrument for flexible endoscopy can safely deliver submucosal tissue samples from submucosal lesions in the upper gastrointestinal tract. © The Author(s) 2016.

The upper GI tract and the colon are readily accessible endoscopically, but the small intestine is relatively difficult to evaluate. To demonstrate the feasibility of using suction as a means of locomotion and to assess the initial design of a suction enteroscope. Feasibility study. Animal laboratory. Various prototype suction devices designed in our laboratory were tested in swine small intestine in a force test station. For in vivo experiments in live anesthetized animals, two suction devices (1 fixed tip and 1 movable tip) were attached to the outside of the endoscope. By creating suction in the fixed tip, the endoscope was anchored while the movable tip was advanced. Suction was then applied to the extended tip to attach it to the distal bowel. Suction on the fixed tip was then released and the movable tip with suction pulled back, resulting in advancement of the endoscope. These steps were sequentially repeated. Intestinal segments were sent for pathologic assessment after testing. Force generated ranged from 0.278 to 4.74 N with 64.3 to 88 kPa vacuum pressure. A linear relationship was seen between the pull force and vacuum pressures and tip surface area. During in vivo experiments, the endoscope was advanced in 25-cm segmental increments with sequential suction-and-release maneuvers. No significant bowel trauma was seen on pathology and necropsy. The enteroscopy system requires further refinement. A novel suction enteroscope was designed and tested. Suction tip characteristics played a critical role impacting the functionality of this enteroscopy system. Copyright © 2012 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc.

Accurate intraoperative localization of esophageal lesions is essential for successful surgical resection. We tested whether preoperative endoscopic placement of titanium clips could facilitate intraoperative localization of early-stage esophageal cancer or severe dysplasia. A prospective randomized clinical trial was performed between May 2012 and July 2014. All enrolled patients received preoperative endoscopy and esophageal endoscopic ultrasound, as well as pathological study on the biopsy specimen, to confirm early stage esophageal cancer or severe dysplasia. One day before the surgical operation, patients in the experimental group received the preoperative endoscopic titanium labeling of esophageal lesions. Then, during the surgical operation, palpitation of titanium clips was used to localize the lesions in these patients. In patients in the control group, palpitation of nodules or esophageal wall mucosal thickening, together with the consideration of the results from preoperative endoscopic and ultrasound studies, was applied to estimate the location of the esophageal lesions. Study outcomes included the proportions of patients having successful intraoperative pre-resection lesion localization, post-esophagectomy lesion visualization, negative upper surgical margin, change of surgical approaches, and positive postoperative pathological diagnosis. A total of 27 patients were enrolled into the study, with 14 in the experimental group and 13 in the control group. Compared to the patients in the control group, a higher proportion of patients in the experimental group had statistically significant successful intraoperative esophageal lesion localization (100 versus 15.3% in the experimental versus control group). Preoperative endoscopic titanium clip placement could facilitate intraoperative localization of early-stage esophageal cancer or severe dysplasia. Current study was registered in Chinese Clinical Trial Registry and World Health Organization International Clinical Trials Registry Platform, ChiCTR-INR-17010949 .

Wide resection of the ureteral orifice (UO) may result in scarring and stenosis of the ureterovesical junction (UVJ). We aimed to describe a technique of endoscopic spatulation of the intramural ureter in patients undergoing resection of the UO at the time of transurethral resection of bladder tumor (TURBT) and compare the surgical and oncological outcomes of this procedure with those of patients undergoing conventional UO resection. The clinical records of patients who underwent TURBT at a single institution were retrospectively analyzed. Patients who underwent conventional UO resection or UO resection followed by endoscopic spatulation of the intramural ureter were included in the analysis. The two groups were compared in terms of intra- and postoperative outcomes. A total of 227 patients were included in the final comparative analyses. Of them, 104 underwent conventional UO resection and 123 underwent UO resection followed by endoscopic spatulation of the intramural ureter. The two groups were comparable for demographic and clinical features. There were not statistically significant differences in terms of mean operative times. The incidence of transient postoperative hydronephrosis as well as UVJ scarring and stenosis was significantly lower in patients undergoing endoscopic spatulation of the intramural ureter. The two groups were similar in terms of incidence of vesicoureteral reflux (VUR) and upper urinary tract cancer recurrence. Endoscopic spatulation of the intramural ureter after UO resection is a safe and quick procedure that significantly reduces the incidence of transient early postoperative hydronephrosis and late UVJ stricture if compared with UO resection alone. This procedure is quick to perform, safe, and does not increase the risk of VUR.

Treatment of frontal sinus using surgery is complicated owing to the complex anatomical structure of the sinus region. The aim of the present study was to investigate the efficacy and safety of Draf IIb endoscopic frontal sinus surgery treatment for frontal sinus lesions using the agger nasi approach on 19 patients (28 left or and right nasal cavities). A 10-12 mm excision of the upper frontal maxilla was performed for endoscopic resection between the middle turbinate and lateral nasal wall. No serious complications in frontal sinus surgery treatment for the removal of the frontal sinus were observed. Patients were followed up after surgery for 6-36 months. Chronic sinusitis and nasal polyps were identified in 10 cases (19 left or and right nasal cavities; disease control, 15 left or and right nasal cavities; and disease partial control, 4 left or and right nasal cavities). Frontal sinus inverted papilloma was observed in 9 cases (9 left or and right nasal cavities). Frontal sinus inverted papilloma were successfully treated in 8 cases, and 1 case of recurrence was observed. In conclusion, the nasal endoscopic Draf IIb agger nasi approach is a minimally invasive treatment for frontal sinus lesions. This surgical procedure is safe and less complicated and may be applied in the clinic.
Reality named endoscopic ultrasound biliary drainage

Endoscopic ultrasound (EUS) is used for diagnosis and evaluation of many diseases of the gastrointestinal (GI) tract. In the past, it was used to guide a cholangiography, but nowadays it emerges as a powerful therapeutic tool in biliary drainage. The aims of this review are: outline the rationale for endoscopic ultrasound-guided biliary drainage (EGBD); detail the procedural technique; evaluate the clinical outcomes and limitations of the method; and provide recommendations for the practicing clinician. In cases of failed endoscopic retrograde cholangiopancreatography (ERCP), patients are usually referred for either percutaneous transhepatic biliary drainage (PTBD) or surgical bypass. Both these procedures have high rates of undesirable complications. EGBD is an attractive alternative to PTBD or surgery when ERCP fails. EGBD can be performed at two locations: transhepatic or extrahepatic, and the stent can be inserted in an antegrade or retrograde fashion. The drainage route can be transluminal, duodenal or transpapillary, which, again, can be antegrade or retrograde [rendezvous (EUS-RV)]. Complications of all techniques combined include pneumoperitoneum, bleeding, bile leak/peritonitis and cholangitis. We recommend EGBD when bile duct access is not possible because of failed cannulation, altered upper GI tract anatomy, gastric outlet obstruction, a distorted ampulla or a periampullary diverticulum, as a minimally invasive alternative to surgery or radiology.

Introduction. Unlike Rockall scoring system, AIMS65 is based only on clinical and laboratory features. In this study we investigated the correlation between the AIMS65 score and Endoscopic Rockall score, in cirrhotic and noncirrhotic patients. Methods. This is a retrospective study of patients admitted with overt UGIB and undergoing esophagogastroduodenoscopy (EGD). AIMS65 and Rockall scores were calculated at the time of admission. We investigated the correlation between both scores along with stigmata of bleed seen on endoscopy. Results. A total of 1255 patients were studied. 152 patients were cirrhotic while 1103 patients were noncirrhotic. There was significant correlation between AIMS65 and Total Rockall scores in patients of both groups. There was significant correlation between AIMS65 score and Endoscopic Rockall score in noncirrhotics but not cirrhotics. AIMS65 scores in both cirrhotic and noncirrhotic groups were significantly higher in patients who died from UGIB than in patients who did not. Conclusion. We observed statistically significant correlation between AIMS65 score and length of hospitalization and mortality in noncirrhotic patients. We found that AIMS65 score paralleled the endoscopic grading of lesion causing UGIB in noncirrhotics. AIMS65 score correlated only with mortality but not the length of hospitalization or endoscopic stigmata of bleed in cirrhotics.

AIM: Late unset of dysphagia due to vascular abnormalities is a rare condition. We aimed to present a case of right subclavian artery abnormalities caused dysphagia in the elderly. METHODS: A 68-year-old female was admitted with dysphagia seven months ago. Upper endoscopic procedures and routine examinations could not demonstrate any etiology. Multislice computed thorax tomography was performed for probable extra- esophagial lesions. RESULTS: Multislice computed thorax tomography showed right subclavian artery abnormality and esophagial compression with this aberrant artery. CONCLUSION: Causes of dysphagia in the elderly are commonly malignancies, strictures and/or motility disorders. If routine examinations and endoscopic procedures fail to show any etiology, rare vascular abnormalities can be considered in such patients. Multislice computed tomography is a usefull choice in such conditions. PMID:15285045

A diospyrobezoar is a type of phytobezoar that is considered to be harder than any other types of phytobezoars. Here, we describe a new treatment modality, which effectively and easily disrupted huge gastric diospyrobezoars. A 41-year-old man with a history of diabetes mellitus was admitted with lower abdominal pain and vomiting. Upper gastrointestinal endoscopy revealed three huge, round diospyrobezoars in the stomach. He was made to drink two cans of Coca-Cola every 6 h. At endoscopy the next day, the bezoars were partially dissolved and turned to be softened. We performed direct endoscopic injection of Coca-Cola into each bezoar. At repeated endoscopy the next day, the bezoars were completely dissolved.

Peptic ulcer disease is a common cause of gastrointestinal bleeding, independent of the patient's age. With advancing age, an increase of lower gastrointestinal bleeding (diverticula, angiodysplasia) has been observed. The administration of non-steroidal anti-inflammatory drugs and aspirin is an important risk factor for upper and lower gastrointestinal bleeding, thus in patients aged 65 years and more a concomitant therapy with proton pump inhibitors is recommended in order to prevent ulcer bleeding. Even in very old individuals endoscopy should be used for the diagnosis of gastrointestinal bleeding, providing the opportunity for definite endoscopic bleeding therapy. In elderly patients with comorbidities and recurrent bleeding after endoscopic therapy or continuous blood loss, surgery or transarterial embolisation should be considered in good time.

Anastomotic stenosis presents as one of the most common late complications in the postoperative period after bariatric surgery. It is often diagnosed by upper gastrointestinal series (UGIS) and/or upper endoscopy (UE). The aim of this study was to determine whether a correlation exists between the Gastrografin UGIS and UE findings in the determination of gastrojejunal anastomotic strictures after Roux-en-Y gastric bypass (RYGB). Between July 2001 and October 2003, all medical records of patients who underwent RYGB at our institution were retrospectively reviewed. The medical records of patients who underwent UE because of symptoms suggestive of gastric outlet obstruction and those of patients who were initially evaluated by Gastrografin UGIS before UE were evaluated further. Of 535 morbidly obese patients who underwent RYGB, 52 (9.7%) had UE and were included in this study. The mean number of UEs performed per patient was 2.67. Of these 52 patients, 30 underwent Gastrografin UGIS before UE. The mean diameter of the anastomosis on the first UE was 5.97 mm and on Gastrografin UGIS was 6.83 mm. A good correlation was found between the Gastrografin UGIS and UE findings using Pearson's correlation coefficient (0.44, P = .02) and single linear regression analysis using the endoscopic diameter as the outcome and radiographic findings as the predictor (beta = 0.27, P = .025, 95% confidence interval 0.30-0.49). In our study, the Gastrografin UGIS findings correlated positively with the endoscopic gastrojejunal anastomosis findings in patients with anastomotic stricture who had undergone RYGB.
Role of Interventional Radiology in the Emergent Management of Acute Upper Gastrointestinal Bleeding
Navuluri, Rakesh; Patel, Jay; Kang, Lisa

Approximately 100,000 cases of upper gastrointestinal bleeding (UGIB) require inpatient admission annually in the United States. When medical management and endoscopic therapy are inadequate, endovascular intervention can be lifesaving. These emergent situations highlight the importance of immediate competence of the interventional radiologist in the preangiographic evaluation as well as the endovascular treatment of UGIB. We describe a case of UGIB managed with endovascular embolization and detail the angiographic techniques used. The case description is followed by a detailed discussion of the treatment approach to UGIB, with attention to both nonvariceal and variceal algorithms. PMID:23997408
[Upper gastrointestinal bleeding: usefulness of prognostic scores].
Badel, S; Dorta, G; Carron, P-N
2011-08-24
Upper gastrointestinal bleeding is a potentially serious event, usually requiring urgent endoscopic treatment. Better stratification of the risk of complication or death could optimize management and improve patient outcomes, while ensuring adequate resource allocation. Several prognostic scores have been developed, in order to identify high risk patients, who require immediate treatment, and patients at low risk for whom endoscopy may be delayed. An ideal prognostic score should be accurate, simple, reproducible, and prospectively validated in different populations. Published scores meet these requirements only partially, and thus can only be used as part of an integrative diagnostic and therapeutic process.

Confocal LASER endomicroscopy (CLE) is a newly developed endoscopic technique which allows subsurface in vivo histological assessment during ongoing endoscopy and targeted biopsies. Ultrasound endoscopy (EUS) is a useful tool in staging upper GI malignant lesions. We describe for the first time the use of both techniques during the same endoscopic session, in a pilot study, in order to increase the diagnostic yield of histological assessment and provide the staging of the gastric neoplastic lesions thus decreasing the time to therapeutic decision. CLE has been performed with the Pentax EG-3870CIK confocal endomicroscope after a 5 ml intravenous 10% fluorescein injection; EUS has been performed subsequently, during the same endoscopic Propofol sedation session, using a standard radial EUS-scope. Eleven patients have been investigated, 4 females, 7 males, mean age 59.7 +/- 12.3 years. The indication of CLE/EUS exploration was the presence of a gastric polypoid lesion in 37% of cases, atypical gastric ulcer in 27% of patients, gastric lymphoma 18%, suspicion of gastric cancer recurrence after resection 9% and infiltrating type gastric cancer 9%. Histological assessment after targeted biopsy has established the diagnosis of gastric adenocarcinoma in 55% of cases, gastric lymphoma in 18% of cases, gastric adenoma, gastric GIST and gastric foveolar hyperplasia in 9% of cases respectively. CLE has allowed targeted biopsies in 81.8% of cases. In 2 patients - one case with suspected recurrent gastric cancer after surgery and one case of gastric lymphoma, CLE has indicated normal gastric mucosa. The EUS evaluation has shown TO lesion in two cases, T1 in 3 cases, T2 in 3 cases, T3 in one case. The EUS evaluation showed in one gastric lymphoma patient a lesion interesting the mucosa and submucosa with regional adenopathy and a submucosal lesion with regional adenopathy in the other gastric lymphoma case. The therapeutic decision was surgery in 73% of cases, chemotherapy and follow-up in 18% of cases and follow-up in 9% of cases. No complications were registered during the CLE/EUS explorations. CLE and EUS can be successfully associated during the same endoscopic session, for upper GI neoplastic lesions allowing targeted biopsies for histological assessment and disease staging for optimal therapeutic decision.
[Laparoscopic Proximal Gastrectomy as a Surgical Treatment for Upper Third Early Gastric Cancer].

Recently, the incidence of upper third gastric cancer has increased, and with it the number of endoscopic submucosal dissection (ESD) procedures performed has been increasing. However, if ESD is not indicated or non-curable, surgical treatment may be necessary. In the case of lower third gastric cancer, it is possible to preserve the upper part of the stomach; however, in the case of upper third gastric cancer, total gastrectomy is still the standard treatment option, regardless of the stage. This is due to the complications associated with upper third gastric cancer, such as gastroesophageal reflux after proximal gastrectomy rather than oncologic problems. Recently, the introduction of the double tract reconstruction method after proximal gastrectomy has become one of the surgical treatment methods for upper third early gastric cancer. However, since there has not been a prospective comparative study evaluating its efficacy, the ongoing multicenter prospective randomized controlled trial (KLASS-05) comparing laparoscopic proximal gastrectomy with double tract reconstruction and laparoscopic total gastrectomy is expected to be important for determining the future of treatment of upper third early gastric cancer.

With the increasing adoption of peroral endoscopic myotomy (POEM) as a first-line therapy for achalasia as well as a growing list of other indications, it is apparent that there is a need for effective training methods for both endoscopists in training and those already in practice. We present a hands-on-focused with pre- and post-testing methodology to teach these skills. Six POEM courses were taught by 11 experienced POEM endoscopists at two independent simulation laboratories. The training curriculum included a pre-training test, lectures and discussion, mentored hands-on instruction using live porcine and ex-plant models, and a post-training test. The scoring sheet for the pre- and post-tests assessed the POEM performance with a Likert-like scale measuring equipment setup, mucosotomy creation, endoscope navigation, visualization, myotomy, and closure. Participants were stratified by their experience with upper-GI endoscopy (Novices <100 cases vs. Experts ≥100 cases), and their data were analyzed and compared. Sixty-five participants with varying degrees of experience in upper-GI endoscopy and laparoscopic achalasia cases completed the training curriculum. Participants improved knowledge scores from 69.7 ± 17.1 (pre-test) to 87.7 ± 10.8 (post-test) (p < 0.01). POEM performance increased from 15.1 ± 5.1 to 25.0 ± 5.5 (out of 30) (p < 0.01) with the greatest gains in mucosotomy [1.7-4.4 (out of 5), p < 0.01] and equipment (3.4-4.7, p < 0.01). Novices had significantly lower pre-test scores compared with Experts in upper-GI endoscopy (overall pre-score: 11.9 ± 5.6 vs. 16.3 ± 4.6, p < 0.01). Both groups improved significantly after the course, and there were no differences in post-test scores (overall post-score: 23.9 ± 6.6 vs. 25.4 ± 5.1, p = 0.34) between Novices and Experts. A multimodal curriculum with procedural practice was an effective curricular design for teaching POEM to practitioners. The curriculum was specifically helpful for training surgeons with less upper-GI endoscopy experience.

AIM: To prospectively assess the impact of time of endoscopy and endoscopist’s experience on the outcome of non-variceal acute upper gastrointestinal (GI) bleeding patients in a large teaching hospital. METHODS: All patients admitted for non-variceal acute upper GI bleeding for over a 2-year period were potentially eligible for this study. They were managed by a team of seven endoscopists on 24-h call whose experience was categorized into two levels (high and low) according to the number of endoscopic hemostatic procedures undertaken before the study. Endoscopic treatment was standardized according to Forrest classification of lesions as well as the subsequent medical therapy. Time of endoscopy was subdivided into two time periods: routine (8 a.m.-5 p.m.) and on-call (5 p.m.-8 a.m.). For each category of experience and time periods rebleeding rate, transfusion requirement, need for surgery, length of hospital stay and mortality we compared. Multivariate analysis was used to discriminate the impact of different variables on the outcomes that were considered. RESULTS: Study population consisted of 272 patients (mean age 67.3 years) with endoscopic stigmata of hemorrhage. The patients were equally distributed among the endoscopists, whereas only 19% of procedures were done out of working hours. Rockall score and Forrest classification at admission did not differ between time periods and degree of experience. Univariate analysis showed that higher endoscopist’s experience was associated with significant reduction in rebleeding rate (14% vs 37%), transfusion requirements (1.8±0.6 vs 3.0±1.7 units) as well as surgery (4% vs 10%), but not associated with the length of hospital stay nor mortality. By contrast, outcomes did not significantly differ between the two time periods of endoscopy. On multivariate analysis, endoscopist’s experience was independently associated with rebleeding rate and transfusion requirements. Odds ratios for low experienced endoscopist were 4.47 for rebleeding and 6.90 for need of transfusion after the endoscopy. CONCLUSION: Endoscopist’s experience is an important independent prognostic factor for non-variceal acute upper GI bleeding. Urgent endoscopy should be undertaken preferentially by a skilled endoscopist as less expert staff tends to underestimate some risk lesions with a negative influence on hemostasis. PMID:16437658

The gastroduodenal artery (GDA) is frequently embolized in cases of upper GI bleed that has failed endoscopic therapy. Additionally, it may be done for GDA pseudoaneurysms or as an adjunctive procedure prior to Yttrim-90 (Y90) treatment of hepatic tumors. This clinical review will summarize anatomy and embryology of the GDA, indications, outcomes and complications of GDA embolization. PMID:29724061
Role of transcatheter arterial embolization for massive bleeding from gastroduodenal ulcers
Loffroy, Romaric; Guiu, Boris
2009-01-01
Intractable bleeding from gastric and duodenal ulcers is associated with significant morbidity and mortality. Aggressive treatment with early endoscopic hemostasis is essential for a favourable outcome. In as many as 12%-17% of patients, endoscopy is either not available or unsuccessful. Endovascular therapy with selective catheterization of the culprit vessel and injection of embolic material has emerged as an alternative to emergent operative intervention in high-risk patients. There has not been a systematic literature review to assess the role for embolotherapy in the treatment of acute upper gastrointestinal bleeding from gastroduodenal ulcers after failed endoscopic hemostasis. Here, we present an overview of indications, techniques, and clinical outcomes after endovascular embolization of acute peptic-ulcer bleeding. Topics of particular relevance to technical and clinical success are also discussed. Our review shows that transcatheter arterial embolization is a safe alternative to surgery for massive gastroduodenal bleeding that is refractory to endoscopic treatment, can be performed with high technical and clinical success rates, and should be considered the salvage treatment of choice in patients at high surgical risk.

European experience in endoscopic mucosal resection (EMR) for early gastric cancer is still relatively low, since early stomach cancer is diagnosed at a much lower rate in Europe than in Japan and generally operable patients are referred to surgery for radical resection. Endoscopic mucosal resection or mucosectomy was developed as a promising technology to diagnose and treat mucosal lesions in the esophagus, stomach and colon. In contrast to surgical resection, EMR allows "early cancers" to be removed with a minimal cost, morbidity and mortality. We present the case of a patient with hepatic cirrhosis incidentally diagnosed with an elevated-type IIa early gastric cancer. Echoendoscopy was performed in order to assess the depth of invasion into the gastric wall confirming the only mucosal involvement. We performed an EMR using "cup and suction" method. After the procedure, the patient experienced an acute upper gastrointestinal bleeding from the ulcer bed requiring argon plasma coagulation. The histopathological examination confirmed an early cancer, without involvement of muscularis mucosae. The patient has had an uneventful evolution being well at six months after the procedure

We report a case of gastric bezoar-induced gastric outlet obstruction that was successfully treated with a combination of endoscopic injection and irrigation with Coca Cola. A 73-year-old diabetic woman had a history of perforated peptic ulcer and had received pyloroplasty more than 20 years previously. She had been ingesting Pho Pu Zi (Cordia dichotoma Forst. f.) as an appetizer for 1 month. She presented with epigastric pain, nausea, and vomiting. Upper gastrointestinal endoscopy, performed at a local hospital, showed 2 gastric bezoars in the stomach, and 1 of them impacted at the pylorus. She was referred to our emergency department for removal of the gastric bezoars that were suspected to be causing gastric outlet obstruction. All attempts at endoscopic removal using a polypectomy snare, biopsy forceps and Dormia basket failed. We then injected Coca Cola directly into the bezoar mass, followed by irrigation with Coca Cola. Follow-up endoscopy was performed the next day, which revealed that the gastric bezoars had dissolved spontaneously.

Bleeding from a pancreatic pseudocyst is a severe complication after pancreatitis that can lead to a massive gastrointestinal blood loss. Pseudocyst rupture into the stomach is an unusual complication. We report the case of a 34-year-old woman with a history of alcoholism and a pancreatic pseudocyst. One year after follow-up of her pseudocyst, she arrived at the emergency room with an episode of upper gastrointestinal bleeding. An upper digestive endoscopy showed active bleeding in the subcardial fundus, which could not be endoscopically controlled. Abdominal angio-CT confirmed the diagnosis of a splenic artery pseudoaneurysm in close contact with the back wall of the stomach, as well as a likely fistulization of it. The patient was urgently operated and a distal splenopancreatectomy and fistulorrhaphy was performed. The rupture of a splenic artery pseudoaneurysm may rarely present as upper gastrointestinal bleeding. This may be lethal if not urgently treated.

Gastroesophageal reflux is considered a risk factor for recurrent or persistent upper and lower respiratory tract conditions including asthma, chronic cough, sinusitis, laryngitis, serous otitis and paroxysmal laryngospasm. Fifty-one subjects with recurrent (more than three) episodes of upper respiratory tract infection (URTI), serous otitis or sinusitis who had been admitted to an earnose- throat (ENT) outpatient clinic during the previous year were enrolled in the present study to evaluate the presence of laryngeal and/or esophageal reflux. The participants, who were randomly selected, were questioned about symptoms of reflux, including vomiting, abdominal pain, failure to thrive, halitosis, bitter taste in the mouth, chronic cough, heartburn, constipation and hoarseness. All subjects had an endoscopic examination, an otoscopic examination, a tympanogram and upper GI system endoscopy. Esophagitis was diagnosed endoscopically and histologically. The likelihood of occurrence of esophagitis was found to be higher only among subjects with postglottic edema/erythema as determined by pathological laryngeal examination. The reflux complaints reported did not predict the development of esophagitis, but the odds of esophagitis occurring were ninefold greater among subjects with recurrent otitis. Of the subjects, 45.1% were Helicobacter pylori-positive. However, no association was found between esophagitis and Helicobacter pylori positivity. The likelihood of the occurrence of esophagitis was found to be increased in the presence of recurrent otitis media and/or postglottic edema, irrespective of the presence of reflux symptoms. We concluded that, in contrast to the situation where adults are concerned, the boundaries for discriminating laryngopharyngeal reflux from gastroesophageal reflux are somewhat blurred in pediatric patients.

Aim: Foreign bodies ingested by the oral route enter into the gastrointestinal tract and are considered a significant health problem in the childhood. In this study, we evaluated the pediatric patients who presented to our hospital with the complaint of ingestion of foreign body. Material and Methods: The hospital records of all children who presented to our clinic because of ingestion of foreign body between January 2008 and January 2015 were examined retrospectively. The complaints at admission, the types of foreign bodies ingested, the localization of the foreign body in the gastrointestinal tract and the approaches and treatment methods used were examined. Results: Thirty-six (56%) of 64 patients included in the study were male and 28 (44%) were female and the mean age was 5.7±4.6 years (10 months–17 years). Thirty eight (59%) of 64 children who were included in the assessment were below the age of five years. The most common complaint at presentation was parental recognition of the ingested object and dysphagia. The most commonly ingested foreign bodies included coins, sewing pins, safety pins and hairclips. Nail clipper detected in the stomach, sewing pin which penetrated through the duodenal wall and stuck to hepatic parenchyma were the first pediatric cases in the literature. Upper esophagus was the most common location for foreign bodies. Endoscopic examinations were performed in 55 of 64 children. Conclusions: Early detection and treatment of ingested foreign bodies in the upper gastrointestinal system is important in terms of preventing possible complications. In our study, the most frequent foreign bodies detected in the upper digestive tract were coins and they were most frequently detected in the upper esophagus. Most of our patients were below the age of five years. Flexible endoscopic method was used commonly for treatment. PMID:26884693

To compare the predictive accuracy and clinical utility of five risk scoring systems in the assessment of patients with upper gastrointestinal bleeding. International multicentre prospective study. Six large hospitals in Europe, North America, Asia, and Oceania. 3012 consecutive patients presenting over 12 months with upper gastrointestinal bleeding. Comparison of pre-endoscopy scores (admission Rockall, AIMS65, and Glasgow Blatchford) and post-endoscopy scores (full Rockall and PNED) for their ability to predict predefined clinical endpoints: a composite endpoint (transfusion, endoscopic treatment, interventional radiology, surgery, or 30 day mortality), endoscopic treatment, 30 day mortality, rebleeding, and length of hospital stay. Optimum score thresholds to identify low risk and high risk patients were determined. The Glasgow Blatchford score was best (area under the receiver operating characteristic curve (AUROC) 0.86) at predicting intervention or death compared with the full Rockall score (0.70), PNED score (0.69), admission Rockall score (0.66, and AIMS65 score (0.68) (all P<0.001). A Glasgow Blatchford score of ≤1 was the optimum threshold to predict survival without intervention (sensitivity 98.6%, specificity 34.6%). The Glasgow Blatchford score was better at predicting endoscopic treatment (AUROC 0.75) than the AIMS65 (0.62) and admission Rockall scores (0.61) (both P<0.001). A Glasgow Blatchford score of ≥7 was the optimum threshold to predict endoscopic treatment (sensitivity 80%, specificity 57%). The PNED (AUROC 0.77) and AIMS65 scores (0.77) were best at predicting mortality, with both superior to admission Rockall score (0.72) and Glasgow Blatchford score (0.64; P<0.001). Score thresholds of ≥4 for PNED, ≥2 for AIMS65, ≥4 for admission Rockall, and ≥5 for full Rockall were optimal at predicting death, with sensitivities of 65.8-78.6% and specificities of 65.0-65.3%. No score was helpful at predicting rebleeding or length of stay. The Glasgow Blatchford score has high accuracy at predicting need for hospital based intervention or death. Scores of ≤1 appear the optimum threshold for directing patients to outpatient management. AUROCs of scores for the other endpoints are less than 0.80, therefore their clinical utility for these outcomes seems to be limited.Trial registration Current Controlled Trials ISRCTN16235737.

We present four cases of hydrocephalus caused by occlusion of foramen of Magendie associated with Chiari Type I malformation and syringomyelia. The aim of this study is to evaluate the results of surgical treatment via fourth ventriculostomy with catheter from the fourth ventricle to the upper cervical subarachnoid space. Obstructive tetraventricular hydrocephalus due to occlusion of the foramina of Luschka and Magendie can be treated with cerebrospinal fluid shunting, opening the membranes with suboccipital craniotomy, placement of a catheter, endoscopic third ventriculostomy, and endoscopic fourth ventriculostomy. Our aim was to solve all the pathologies such as Chiari malformation, hydrocephalus, and syringomyelia in one approach. Thus, the treatment consisted of posterior fossa decompression and exploration. All the patients were treated with suboccipital craniectomy and C1 laminectomy with excision of the membrane obstructing the foramen of Magendie. Fourth ventriculostomy with cathetering from fourth ventricle to upper cervical subarachnoid space was performed. The postoperative period was uneventful in all the patients. Neurological status of all the patients improved. Tetraventricular hydrocephalus and syrinx were reduced in the control cranial magnetic resonance imaging. Complications such as infection and catheter migration were not observed during the follow-up period. Treatment with fourth ventriculostomy using a catheter from fourth ventricle to upper cervical subarachnoid space could be a treatment of choice in cases with hydrocephalus caused by occlusion of the foramina of Magendie, with associated Chiari Type I malformation and syringomyelia.

Gastric stump carcinoma was initially reported by Balfore in 1922, and many reports of this disease have since been published. We herein review previous reports of gastric stump carcinoma with respect to epidemiology, carcinogenesis, Helicobacter pylori (H. pylori) infection, Epstein-Barr virus infection, clinicopathologic characteristics and endoscopic treatment. In particular, it is noteworthy that no prognostic differences are observed between gastric stump carcinoma and primary upper third gastric cancer. In addition, endoscopic submucosal dissection has recently been used to treat gastric stump carcinoma in the early stage. In contrast, many issues concerning gastric stump carcinoma remain to be clarified, including molecular biological characteristics and the carcinogenesis of H. pylori infection. We herein review the previous pertinent literature and summarize the characteristics of gastric stump carcinoma reported to date.

We describe a long-range optical coherence tomography system for size and shape measurement of large hollow organs in the human body. The system employs a frequency-domain optical delay line of a configuration that enables the combination of high-speed operation with long scan range. We compare the achievable maximum delay of several delay line configurations, and identify the configurations with the greatest delay range. We demonstrate the use of one such long-range delay line in a catheter-based optical coherence tomography system and present profiles of the human upper airway and esophagus in vivo with a radial scan range of 26 millimeters. Such quantitative upper airway profiling should prove valuable in investigating the pathophysiology of airway collapse during sleep (obstructive sleep apnea).

Duodenal ulcer is the most common peptic ulcer disease worldwide. In the past, sub-Saharan Africa has been described as an area of mixed prevalence for peptic ulcer disease, but recent reports have disputed this. Changes in the prevalence of duodenal ulcer have been reported, with various reasons given for these. To describe the change in endoscopic prevalence of duodenal ulcer at Obafemi Awolowo University Teaching Hospital (OAUTH), Ile-Ife, Nigeria, between January 2000 and December 2010. This was a retrospective, descriptive study of patients who underwent upper gastrointestinal endoscopy in the endoscopy unit of OAUTH between January 2000 and December 2010. The data were obtained from the endoscopy register, demographic indices, presenting symptoms and post-endoscopic diagnoses being retrieved for each patient. The study period was divided into the years 2000 - 2004 and 2005 - 2010, the frequencies of duodenal ulcer and other post-endoscopic diagnoses being compared between these two time periods to see whether there were changes. Over the study period, 292 patients (15.8%) were diagnosed with duodenal ulcer, second only to 471 patients (26.2%) with acute gastritis. The prevalence of duodenal ulcer for 2000 - 2004 was 22.9% (n=211 patients) compared with 9.2% (n=81) for 2005 - 2010 (p<0.001). There was a significant decline in the endoscopic prevalence of duodenal ulcer over the decade.

We present a case report regarding a 74-year-old male with iatrogenic esophageal perforation, after an attempt to remove a food bolus impaction at Lannier’s triangle (proximal esophagus). The perforation was treated endoscopically (flexible EGD) by clip application in two sessions, with excellent outcome. Esophageal perforations occur rarely, usually following a medical procedure. The clinical manifestations are often insidious with potentially catastrophic complications. Although the majority of cases have been treated conservatively and/or operatively over the years, there is a rising tendency for non-operative endoscopic interventions due to the high morbidity and mortality rates seen even in specialized units. For this reason self-expandable stents, endoclips, tissue sealants and suturing devices have been used. A high degree of clinical suspicion is essential for successful management of esophageal perforations, as is early decision to intervene and respect for basic surgical principles such as prevention and limitation of extraesophageal contamination, prevention of reflux of gastric contents and restoration of gastrointestinal tract integrity. The published reports on the use of endoclips for repairing perforations of the proximal esophagus are rare. To our knowledge, this is the first case report regarding the endoscopic application of endoclips for the successful closure of an iatrogenic perforation at Lannier’s triangle. PMID:24714287

The Spigelman classification stratifies cancer risk in familial adenomatous polyposis (FAP) patients with duodenal adenomatosis. High-resolution endoscopy (HRE) and narrow-band imaging (NBI) may identify lesions at high risk. To compare HRE and NBI for the detection of duodenal and gastric polyps and to characterize duodenal adenomas harboring advanced histology with HRE and NBI. Prospective, nonrandomized, comparative study. Retrospective image evaluation study. Tertiary-care center. Thirty-seven FAP patients undergoing surveillance upper endoscopies. HRE endoscopy was followed by NBI. The number of gastric polyps and Spigelman staging were compared. Duodenal polyp images were systematically reviewed in a learning and validation phase. Number of gastric and duodenal polyps detected by HRE and NBI and prevalence of specific endoscopic features in duodenal adenomas with advanced histology. NBI did not identify additional gastric polyps but detected more duodenal adenomas in 16 examinations, resulting in upgrades of the Spigelman stage in 2 cases (4.4%). Pictures of 168 duodenal adenomas (44% advanced histology) were assessed. In the learning phase, 3 endoscopic features were associated with advanced histology: white color, enlarged villi, and size ≥1 cm. Only size ≥1 cm was confirmed in the validation phase (odds ratio 3.0; 95% confidence interval, 1.2-7.4). Nonrandomized study, scant number of high-grade dysplasia adenomas. Inspection with NBI did not lead to a clinically relevant upgrade in the Spigelman classification and did not improve the detection of gastric polyps in comparison with HRE. The only endoscopic feature that predicted advanced histology of a duodenal adenoma was size ≥1 cm. Copyright © 2013 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc.

Background Several types of forceps are available for use in sampling Barrett’s esophagus (BE). Few data exist with regard to biopsy quality for histologic assessment. Objective To evaluate sampling quality of 3 different forceps in patients with BE. Design Single-center, randomized clinical trial. Patients Consecutive patients with BE undergoing upper endoscopy. Interventions Patients randomized to have biopsy specimens taken with 1 of 3 types of forceps: standard, large capacity, or jumbo. Main Outcome Measurements Specimen adequacy was defined a priori as a well-oriented biopsy sample 2 mm or greater in diameter and with at least muscularis mucosa present. Results A total of 65 patients were enrolled and analyzed (standard forceps, n = 21; large-capacity forceps, n = 21; jumbo forceps, n = 23). Compared with jumbo forceps, a significantly higher proportion of biopsy samples with large-capacity forceps were adequate (37.8% vs 25.2%, P = .002). Of the standard forceps biopsy samples, 31.9% were adequate, which was not significantly different from specimens taken with large-capacity (P = .20) or jumbo (P = .09) forceps. Biopsy specimens taken with jumbo forceps had the largest diameter (median, 3.0 mm vs 2.5 mm [standard] vs 2.8 mm [large capacity]; P = .0001). However, jumbo forceps had the lowest proportion of specimens that were well oriented (overall P = .001). Limitations Heterogeneous patient population precluded dysplasia detection analyses. Conclusions Our results challenge the requirement of jumbo forceps and therapeutic endoscopes to properly perform the Seattle protocol. We found that standard and large-capacity forceps used with standard upper endoscopes produced biopsy samples at least as adequate as those obtained with jumbo forceps and therapeutic endoscopes in patients with BE.

There have been no studies investigating the distribution of abnormal gastroesophageal flap valve (GEFV) among patients with dyspepsia, non-erosive reflux disease (NERD), and reflux esophagitis (RE) in the same set of patients. The aims of this study are to investigate (1) the association between GEFV and gastroesophageal reflux disease questionnaire (GERDQ) score, and (2) the distribution of abnormal GEFV in Vietnamese patients presenting with upper gastrointestinal symptoms. Three hundred and thirty-one patients recruited in this prospective cross-sectional study were classified into 3 groups: reflux esophagitis (RE), non-erosive reflux disease (NERD) (GERDQ score ≥ 8, no endoscopic mucosal injury), and dyspepsia (GERDQ score < 8, no endoscopic mucosal injury). The GEFV was graded endoscopically according to the Hill classification. GEFV grades I and II were regarded as normal, while grades III and IV were regarded as abnormal GEFV. There were 215 (65.0%) patients with dyspepsia, 55 (16.6%) patients with NERD, and 61 (18.4%) patients with RE. Abnormal GEFV was an independent risk factor for GERD (OR, 2.93; CI 95%, 1.76-4.88) and RE (OR, 3.41; CI 95%, 1.78-6.53). The mean GERDQ score of patients with abnormal GEFV was significantly higher than that of patients with normal GEFV (5.7 ± 2.4 vs 4.9 ± 2.7, P = 0.011). The prevalence of abnormal GEFV gradually increased in patients with dyspepsia (27.4%), NERD (43.6%), grade A RE (56.8%), and grades B/C RE (80.0%) ( P < 0.001). Abnormal GEFV was significantly associated with high GERDQ score. Its prevalence gradually increased in patients with dyspepsia, NERD, and RE, respectively.

Contrast-enhanced endoscopic ultrasonography (CE-EUS) was introduced in the early 1990s. The concept of the injection of carbon dioxide microbubbles into the hepatic artery as a contrast material (enhanced ultrasonography) led to "endoscopic ultrasonographic angiography". After the arrival of the first-generation contrast agent, high-frequency (12 MHz) EUS brought about the enhancement of EUS images in the diagnosis of pancreatico-biliary diseases, upper gastrointestinal (GI) cancer, and submucosal tumors. The electronic scanning endosonoscope with both radial and linear probes enabled the use of high-end ultrasound machines and depicted the enhancement of both color/power Doppler flow-based imaging and harmonic-based imaging using second-generation contrast agents. Many reports have described the usefulness of the differential diagnosis of pancreatic diseases and other abdominal lesions. Quantitative evaluation of CE-EUS images was an objective method of diagnosis using the time-intensity curve (TIC), but it was limited to the region of interest. Recently developed Inflow Time Mapping™ can be generated from stored clips and used to display the pattern of signal enhancement with time after injection, offering temporal difference of contrast agents and improved tumor characterization. On the other hand, three-dimensional CE-EUS images added new information to the literature, but lacked positional information. Three-dimensional CE-EUS with accurate positional information is awaited. To date, most reports have been related to pancreatic lesions or lymph nodes. Hemodynamic analysis might be of use for diseases in other organs: upper GI cancer diagnosis, submucosal tumors, and biliary disorders, and it might also provide functional information. Studies of CE-EUS in diseases in many other organs will increase in the near future.

In the UK, the majority of diagnostic upper gastrointestinal (UGI) endoscopies are a result of direct-to-test referral from the primary care physician. The diagnostic yield of these tests is relatively low, and the burden high on endoscopy services. Dual-focus magnification, high-definition endoscopy is expected to improve detection and classification of UGI mucosal lesions and also help minimize biopsies by allowing better targeting. This is a retrospective study of patients attending for direct-to-test UGI endoscopy from January 2015 to June 2015. The primary outcome of interest was the identification of significant pathology. Detection of significant pathology was modelled using logistic regression. 500 procedures were included. The mean age of patients was 61.5 (±15.6) years; 60.8% of patients were female. Ninety-four gastroscopies were performed using dual-focus magnification high-definition endoscopy. Increasing age, male gender, type of endoscope, and type of operator were all identified as significant factors influencing the odds of detecting significant mucosal pathology. Use of dual-focus magnification, high-definition endoscopy was associated with an odds ratio of 1.87 (95%CI 1.11-3.12) favouring the detection of significant pathology. Subsequent analysis suggested that the increased detection of pathology during dual-focus magnification, high-definition endoscopy also influenced patient follow-up and led to a 3.0 fold (p=0.04) increase in the proportion of patients entered into an UGI endoscopic surveillance program. Dual-focus magnification, high-definition endoscopy improved the diagnostic yield for significant mucosal pathology in patients referred for direct-to-test endoscopy. If this finding is recapitulated elsewhere it will have substantial impact on the provision of UGI endoscopic services.

BACKGROUND: Transnasal esophagogastroduodenoscopy (EGD) without sedation has been reported to be safe and tolerable. It has recently been used widely in Japan for the detection of upper gastrointestinal disease. Alternatively, transoral examination using a thin endoscope has also been reported to be highly tolerable. OBJECTIVE: To examine the cardiocirculatory effects of transoral versus transnasal EGD in an attempt to determine the most suitable endoscopic methods for patients ≥75 years of age. METHODS: Subjects who underwent monitoring of respiratory and circulatory dynamics without sedation during endoscopic screening examinations were enrolled at the New Ooe Hospital (Kyoto, Japan) between April 2008 and March 2009. A total of 165 patients (age ≥75 years) provided written informed consent and were investigated in the present study. Patients were randomly divided into three subgroups: UO group – thin endoscope; SO group – standard endoscope; and UT group – transnasal EGD. Percutaneous arterial blood oxygen saturation, heart rate and blood pressure were evaluated just before EGD and at five time points during EGD. After transnasal EGD, patients who had previously been examined using transoral EGD with a standard endoscope were asked about preferences for their next examination. RESULTS: There were no statistical differences in the characteristics among the groups. Percutaneous oxygen saturation in the UT group showed a transient drop compared with the SO and UO groups at the beginning of the endoscopic procedure. Heart rate showed no significant differences among the SO, UO and UT groups; Systolic blood pressure in the UO group was lower immediately after insertion compared with the SO and UT groups. The rate pressure product in the UO group was comparable with that in the UT group during endoscopy, and the SO group showed a continuously higher level than the UO and UT groups. More than one-half (54.4%) of patients were ‘willing to choose transnasal EGD for next examination’. CONCLUSIONS: For elderly patients, unsedated transnasal EGD failed to show an advantage over unsedated standard endoscopy. Transoral thin EGD was estimated to be safe and tolerable. PMID:24288691

Gastro-entero anastomosis with flexible endoscope with the help of rare-earth magnets on biosynthetic model made of the gastrointestinal tract of slaughtered pigs Numerous malignant diseases may cause gastric outlet obstruction. The surgical gastrointestinal bypass, besides the fact that it requires narcosis, is also associated with high risks for patients with poor general condition. Endoscopic insertion of self-expandable metal stent is less invasive, but often causes complications. In the last years some studies examined a new minimal invasive technique, in which magnets are used to create gastroenteric anastomosis. A biosynthetic model was developed from combined synthetic materials with biogenic specimens taken from slaughtered domestic pigs. The procedure was performed with endoscopic and fluoroscopic guidance. To increase X-ray contrast differences the model was put into physiological saline solution. Two rare-earth magnets (Br: 2500 Gauss, D: 10 mm) with central hole were inserted with the help of a guiding wire and duodenal probe. The first magnet was placed in the first jejunal loop; the second one was placed in the stomach. The gastric magnet was maneuvered using the endoscope. When the magnets reached the right position, the guiding wires were removed to let the magnets stick together. The pressure between the magnets will result in a sterile inflammation on the living tissue which develops adhesion between the bowels, and 7-10 days later anastomosis will develop as a result of the necrosis. The biosynthetic model could be used for training endoscopy without sacrificing animals. In the end of the procedure the magnets stuck together across gastric and jejunal walls in all ten cases successfully. By practice the period necessary for the procedure could be decreased from 40 to 20 minutes. The technique could be made with standard upper endoscope and instruments, and after practice on living animals it could potentially be a useful solution for complaints of gastric outlet obstruction.

A total of 30 consecutive morbidly obese patients, six males and 24 females, who underwent vertical banded gastroplasty (VBG) between January 1992 and December 1994 and were followed up by endoscopy and biopsy were included in this study with the aim to determine the short- and mid-term complications and to investigate alterations in esophageal, gastric, and duodenal mucosa after surgery. All patients underwent endoscopy before operation. Postoperatively, 28 patients were reendoscoped at 6 months, 26 at 12 months, and 22 at 18 months. Biopsies were taken from the lower part of esophagus, just below the esophagogastric junction (vertical part of the partitioned stomach), corpus, antrum, and duodenal bulb. Before operation 5 patients (16.6%) had a hiatus hernia and four of them (13.3%) had esophagitis. Endoscopic gastritis was diagnosed in nine patients (30%) and endoscopic duodenitis in two (6. 6%). Histologically, in 15 patients (50%) esophagitis was recognized; in 24 patients (80%) corpus gastritis; in 27 patients (90%) antral gastritis; and in 23 (76.6%) duodenitis. Helicobacter pylori was found in 20 (66.6%) patients. Postoperatively, three patients developed a mild stoma stenosis and were treated only by passing the endoscope 6 months after operation; one patient, with a severe stoma stenosis, was treated by Eder-Puestow dilatations and surgery. Gastric ulcer was found in two patients 6 and 12 months after surgery. One patient developed an endostomach channel because of staple line dehiscence 18 months after VBG. An increasing incidence of esophagitis and gastritis of the vertical part of the stomach was found at 6 and 12 months. Endoscopic and histologic gastritis of the corpus and antrum, as well as endoscopic and histologic duodenitis decreased gradually after surgery. Our findings suggest that postoperative complications of VBG can be diagnosed by endoscopy, and some of them can easily be managed. Vertical banded gastroplasty causes not only no harm to the esophageal, gastric, and duodenal mucosa but also influences them favorably.

Gastric antral vascular ectasia (GAVE) or 'watermelon stomach' is a rare and often misdiagnosed cause of occult upper gastrointestinal bleeding. Treatment includes conservative measures such as transfusion and endoscopic therapy. A recent report suggests that endoscopic band ligation (EBL) offers an effective alternative treatment. The aim of the present study is to demonstrate our experiences with this novel technique, and to compare argon plasma coagulation (APC) with EBL in terms of safety and efficacy. A retrospective analysis of all endoscopies with a diagnosis of GAVE was carried out between 2004 and 2010. Case records were examined for information pertaining to the number of procedures carried out, mean blood transfusions, mean hemoglobin, and complications. A total of 23 cases of GAVE were treated. The mean age was 73.9 (55-89) years. Female to male ratio was 17:6 and mean follow up was 26 months. Eight patients were treated with EBL with a mean number of treatments of 2.5 (1-5). This resulted in a statistically significant improvement in the endoscopic appearance and a trend towards fewer transfusions. Of the eight patients treated with EBL, six (75%) patients had previously failed APC treatment despite having a mean of 4.7 sessions. Band ligation was not associated with any short- or medium-term complications. The 15 patients who had APC alone had a mean of four (1-11) treatments. Only seven (46.7%) of these patients had any endoscopic improvement with a mean of four sessions. EBL represents a safe and effective treatment for GAVE. © 2012 The Authors.

Improvement in the Reflux Symptom Index Following Surgery for Cricopharyngeal Dysfunction.
Jiang, Nancy; Sung, C Kwang; Damrose, Edward J

Gastroesophageal reflux may contribute to the development of cricopharyngeal dysfunction and Zenker's diverticulum. Common dictum suggests that if upper esophageal sphincter tone is reduced through cricopharyngeal myotomy, symptoms of laryngopharyngeal reflux may worsen. We hypothesized that patients who undergo myotomy should show decreased dysphagia symptoms with concurrent worsening of reflux symptomatology and that these changes would be greater in those patients undergoing complete versus partial myotomy. A retrospective chart review was performed for patients who underwent endoscopic or open cricopharyngeal myotomy, with or without Zenker's diverticulectomy. Preoperative and postoperative reflux symptomatology was subjectively measured with the Reflux Symptom Index (RSI), and dysphagia symptomatology was measured with the Eating Assessment Tool 10 (EAT-10). Patients who underwent partial myotomy via endoscopic stapling of Zenker's diverticulum were compared with patients who underwent complete myotomy (either endoscopic laser-assisted or via an open transcervical approach). The patients were further subdivided into three groups for data analysis: endoscopic staple diverticulotomy, laser cricopharyngeal myotomy, and open approach. A total of 41 patient charts were reviewed. Of these 41 patients, 17 underwent endoscopic stapler-assisted diverticulotomy, 4 underwent endosopic laser-assisted cricopharyngeal myotomy, and 20 underwent open transcervical cricopharyngeal myotomy, with diverticulectomy as indicated. Mean pre- and postoperative RSIs were 21.8 and 8.9, respectively (P < 0.001). Mean pre- and postoperative EAT-10 scores were 19.1 and 5.0, respectively (P < 0.001). Patients' reflux symptoms significantly improved after cricopharyngeal myotomy, with significant improvement in dysphagia symptoms. Concern for worsening of reflux symptoms following surgery does not appear to be clinically common. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

AIM—To document the results of erbium (Er)-YAG laser treatment in presaccal canalicular obstruction in combination with the use of a flexible endoscope. METHODS—For the first time an Er-YAG laser (Schwind, Sklerostom) was attached to a flexible endoscope (Schwind, Endognost) and used to recanalise a stenosis of the upper, lower, or common canaliculus. In 17 patients (mean age 41.5 (SD 11.9) years), 19 treatments (two bilateral) were performed. In all cases the scar was observed using the endoscope and was excised by laser ablation. A silicone intubation was performed in all cases. In addition to the endoscopy an irrigation was performed to prove the intactness of the lacrimal pathway system after laser treatment. RESULTS—Membranous obstructions with a maximum length of 2.0 mm (14 procedures) in the canaliculus were opened easily using the laser, and the silicone intubation was subsequently performed without difficulty. Scars thicker than 2.0 mm could not be opened safely without canaliculus penetration (five procedures). Irrigation was positive in all cases up to the end of a 6 month period, providing the tubes remained in place. The maximum follow up is now 17 months (minimum 8 months) and in 16 cases (84.2%) the canaliculi are still intact. CONCLUSION—Endoscopic laser treatment combined with silicone intubation enables us to recanalise presaccal stenoses of canaliculi under local anaesthesia up to a scar thickness of 2.0 mm. Best results can be achieved in cases where much tissue can be saved. Under such conditions this procedure can substitute for more invasive surgical techniques, especially a conjunctivo-dacryocystorhinostomy (CDCR).

Background. Upper gastrointestinal bleeding is a major cause of morbidity and mortality in patients with portal hypertension secondary to schistosomiasis mansoni. To evaluate the efficacy of combined surgery and sclerotherapy versus endoscopic treatment alone in the prophylaxis of esophageal variceal rebleeding due to portal hypertension in schistosomiasis. During a two-years period consecutive patients with schistosomiasis and a recent bleeding history were evaluated for prospective randomization. Absolute exclusion criteria were alcoholism or other liver diseases, whereas platelet count < 50,000/mm3, INR > 1.5 or presence of gastric varices were relative exclusion criteria. By random allocation 25 (group A) have received endoscopic sclerotherapy for esophageal varices alone and 22 (group B) combined treatment: esophagogastric devascularization with splenectomy followed by sclerotherapy. Interim analysis at 24 months has shown significant statistical differences between the groups and the randomization was halted. Mean age was 38.9 ± 15.4 years and 58.46% were male. Mean follow-up was 38.6 ± 20.1 months. Endoscopic comparison of the size of esophageal varices before and after treatment did not show significant differences among the two groups. Treatment efficacy was assessed by the rate of recurrent esophageal variceal bleeding, that was more common in group A- 9/25 patients (36.0%) vs. 2/22 (9.0%) in group B (p = 0.029). Other complications were odynophagia, dysphagia and esophageal ulcer in group A and ascites and portal vein thrombosis in the surgical group. In portal hypertension due to schistosomiasis, combined surgical and endoscopic treatment was more effective for the prevention of recurrent esophageal variceal bleeding.

Duodenal perforations during diagnostic upper endoscopy are rare; however, when therapeutic techniques are performed, the reported incidence is as great as 2.8%. Surgical repair is usually mandated, but it is associated with significant morbidity and mortality. To compare closure of duodenal perforations by using an over-the-scope clip (OTSC) with a surgical closure. Randomized, controlled animal study. Animal facility laboratory. Domestic pigs (24 females). Large (10-mm) duodenal perforations were created by using an endoscopic needle-knife. The animals were randomly assigned to either open surgical repair (n=12) or endoscopic closure by using the OTSC system (n=12). Pressurized leak tests were performed during necropsy. One major bleed occurred because of a liver injury during creation of the duodenotomy. Mean time for endoscopic closure was 5 minutes (range, 3-8 min; SD +/- 2). No complications occurred during any of the closure procedures. At necropsy, all OTSC and surgical closures demonstrated complete sealing of duodenotomy sites. Pressurized leak tests demonstrated a mean burst pressure of 166 mm Hg (range, 80-260; SD +/- 65) for OTSC closures and 143 mm Hg (range, 30-300, SD +/- 83) for surgical sutures. Ex vivo intact duodenal specimens exhibited a mean burst pressure of 247 mm Hg (range, 200-300; SD +/- 35), which was significantly higher compared with in vivo OTSC and surgical closures (P < .01). There were no significant differences between burst pressures of OTSC and surgical closures (P = .461). Nonsurvival setting. Endoscopic closure of duodenal perforations by using the OTSC system is comparable with surgical closure in a nonsurvival porcine model. This technique is easy to perform and seems suitable for repairing duodenal perforations. 2010 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc. All rights reserved.

During 1991-1997 period 37 patients with foreign bodies in the esophagus were treated in our clinic. In 36 cases the foreign body was "starlet". That is a construction made for this special purpose. It lodges mainly in the upper digestive tract. The most usual localization is the middle third of the esophagus. Unlike the foreign bodies that impact there by accident the operative activity is very high in these cases. Out of the total number of 37 patients 22 were operated, in 7 cases an endoscopic extraction was performed and in one case the foreign body eliminated spontaneously. Three patients died before we performed any manipulations whatsoever and four of them refused any treatment. We offer methods for treating such patients which in our opinion are the most appropriate ones for this type of pathology.
[Longterm controls after endoscopic papillotomy [EPT] (author's transl)].

1980-10-01
In 117 patients who have undergone endoscopic papillotomy (EPT) long term controls have been done. 51 were controlled in the hospital and 66 did answer a questionnaire. The mean time interval to the EPT was mean = 21.6 months. Nine out of every ten patients had no complaints. One third had minimal changes of laboratory dates, which can easily be explained by second diseases. With nearly no exception there was a large orifice to the common bile duct at the upper brim of the papilla. There was no bilioduodenal pressure gradient in 75%. Duodenobiliary reflux could be demonstrated in 25% and aerobilia in 65%. Although there was a massive bacteriobilia in all cases, no signs of cholangitis could be found in any patient. As a result, no unfavourable effects of the EPT became obvious during this follow-up study.

AIM: To analyze reliability among endoscopists in diagnosing portal hypertensive gastropathy (PHG) and to determine which criteria from the most utilized classifications are the most suitable. METHODS: From January to July 2009, in an academic quaternary referral center at Santa Casa of São Paulo Endoscopy Service, Brazil, we performed this single-center prospective study. In this period, we included 100 patients, including 50 sequential patients who had portal hypertension of various etiologies; who were previously diagnosed based on clinical, laboratory and imaging exams; and who presented with esophageal varices. In addition, our study included 50 sequential patients who had dyspeptic symptoms and were referred for upper digestive endoscopy without portal hypertension. All subjects underwent upper digestive endoscopy, and the images of the exam were digitally recorded. Five endoscopists with more than 15 years of experience answered an electronic questionnaire, which included endoscopic criteria from the 3 most commonly used Portal Hypertensive Gastropathy classifications (McCormack, NIEC and Baveno) and the presence of elevated or flat antral erosive gastritis. All five endoscopists were blinded to the patients’ clinical information, and all images of varices were deliberately excluded for the analysis. RESULTS: The three most common etiologies of portal hypertension were schistosomiasis (36%), alcoholic cirrhosis (20%) and viral cirrhosis (14%). Of the 50 patients with portal hypertension, 84% were Child A, 12% were Child B, 4% were Child C, 64% exhibited previous variceal bleeding and 66% were previously endoscopic treated. The endoscopic parameters, presence or absence of mosaic-like pattern, red point lesions and cherry-red spots were associated with high inter-observer reliability and high specificity for diagnosing Portal Hypertensive Gastropathy. Sensitivity, specificity and reliability for the diagnosis of PHG (%) were as follows: mosaic-like pattern (100; 92.21; High); fine pink speckling (56; 76.62; Unsatisfactory); superficial reddening (69.57; 66.23; Unsatisfactory); red-point lesions (47.83; 90.91; High); cherry-red spots (39.13; 96.10; High); isolated red marks (43.48; 88.31; High); and confluent red marks (21.74; 100; Unsatisfactory). Antral elevated erosive gastritis exhibited high reliability and high specificity with respect to the presence of portal hypertension (92%) and the diagnosis of portal hypertensive gastropathy (88.31%). CONCLUSION: The most suitable endoscopic criteria for the diagnosis of PHG were mosaic-like pattern, red-point lesions and cherry-red spots with no subdivisions, which were associated with a high rate of inter-observer reliability.

Endoscopic ultrasound (EUS) has developed significantly over the last two decades and has had a considerable impact on the imaging and staging of mass lesions within or in close proximity to the gastrointestinal (GI) tract. In conjunction with conventional imaging such as helical computed tomography and magnetic resonance imaging, the indications for EUS include (1) differentiating between benign and malignant lesions of the mediastinum and upper GI tract, (2) staging malignant tumors of the lung, esophagus, stomach, and pancreas prior to surgery or oncological treatment, (3) excluding common bile duct stones before laparoscopic cholecystectomy, thereby avoiding the need for endoscopicmore » retrograde cholangiopancreatography (ERCP) in some patients, and (4) assessing suspected lesions that are either equivocal or not seen on conventional imaging. In recent years, EUS has charted a course similar to that taken by ERCP, evolving from a purely diagnostic modality to one that is interventional and therapeutic. These indications include (5) obtaining a tissue diagnosis by EUS-guided fine-needle aspiration or trucut-type needle biopsy and (6) providing therapy such as coeliac plexus neurolysis and pancreatic pseudocyst drainage-in many cases, more accurately and safely than conventional techniques. Emerging investigational techniques include EUS-guided enteric anastomosis formation and fine-needle injection therapy for malignant disease.« less
Diagnosis and therapy of non-variceal upper gastrointestinal bleeding
Biecker, Erwin
2015-01-01
Non-variceal upper gastrointestinal bleeding (UGIB) is defined as bleeding proximal to the ligament of Treitz in the absence of oesophageal, gastric or duodenal varices. The clinical presentation varies according to the intensity of bleeding from occult bleeding to melena or haematemesis and haemorrhagic shock. Causes of UGIB are peptic ulcers, Mallory-Weiss lesions, erosive gastritis, reflux oesophagitis, Dieulafoy lesions or angiodysplasia. After admission to the hospital a structured approach to the patient with acute UGIB that includes haemodynamic resuscitation and stabilization as well as pre-endoscopic risk stratification has to be done. Endoscopy offers not only the localisation of the bleeding site but also a variety of therapeutic measures like injection therapy, thermocoagulation or endoclips. Endoscopic therapy is facilitated by acid suppression with proton pump inhibitor (PPI) therapy. These drugs are highly effective but the best route of application (oral vs intravenous) and the adequate dosage are still subjects of discussion. Patients with ulcer disease are tested for Helicobacter pylori and eradication therapy should be given if it is present. Non-steroidal anti-inflammatory drugs have to be discontinued if possible. If discontinuation is not possible, cyclooxygenase-2 inhibitors in combination with PPI have the lowest bleeding risk but the incidence of cardiovascular events is increased. PMID:26558151

Hematemesis and acute postsurgical upper gastrointestinal hemorrhage are common emergent on-call consultations for the interventional radiologist. Upper GI bleleding (UGIB) is a relatively frequent problem. The incidence and mortality vary among patient populations, but studies have shown an overall incidence ranging from 36-172 cases per 100,000 adults per year, with a mortality rate of 5%-14%. The incidence is significantly higher in men. Peptic ulcer disease is the predominant etiology, responsible for 28%-59% of UGIB. Other causes include varices, mucosal erosive disease, Mallory-Weiss syndrome, and malignancy. After assessment of hemodynamic status and airway stability with resuscitative efforts as needed, initial consultation with gastroenterology for endoscopic evaluation and treatment is well regarded as the initial therapeutic strategy. Angiography with embolization and interventional techniques directed at managing variceal hemorrhage have emerged as very capable second-line strategies for patients who have failed endoscopic therapy. In certain circumstances, the interventional radiologist may be called upon as the first line, notably for patients who have had recent surgical intervention or who have extraluminal hemorrhage. As the role of the interventional radiologist in the evaluation and treatment of UGIB continues to evolve, familiarity and knowledge of how to deal with these urgent and emergent clinical scenarios becomes paramount.

Although proximal gastrectomy has become a procedure of choice for patients' early cancer in the upper third of stomach, no clinical guide for optimal gastric resection in order to avoid postoperative jejunal ulcer is available. The aim of this study was to investigate whether determining the distribution of parietal and chief cells of the stomach using Congo red test is clinically relevant. The F-line was defined as a boundary line between fundic and intermediate area of the stomach according to the pathological findings in 29 patients who underwent total gastrectomy for early gastric cancer, whereas the f-line was regarded as a boundary line between intermediate and pyloric area. In the additional 6 patients undergoing vagus-preserving proximal gastrectomy with jejunal pouch interposition, endoscopic Congo red test was preoperatively performed to determine the F-f-line. The distances from the pyloric ring to f-line on the lesser and greater curvatures were variable. Long-term outcomes of proximal gastrectomy guided by preoperative endoscopic Congo red test were favorable. It is suggested that preoperative endoscopic Congo red test is useful to determine the appropriate cutting line in order to avoid postoperative jejunal ulcer after proximal gastrectomy.

We report a novel method for in situ imaging of microvascular permeability in inflamed gingival tissue, using state-of-the-art Cellvizio™ intravital endoscopic technology and a mouse model of ligature-induced periodontitis. The silk ligature was first placed at the upper left second molar. Seven days later, the ligature was removed, and the animals were intravenously injected with Evans blue. Evans blue dye, which selectively binds to blood albumin, was used to monitor the level of inflammation by monitoring vascular permeability in control non-diseased and ligature-induced experimental periodontitis tissue. More specifically, leakage of Evans blue-bound albumin from the micro-capillary to connective tissue indicates the state of inflammation occurring in the specific site. Evans blue leakage from blood vessels was imaged in situ by directly attaching the endoscope (mini Z tip) of the Cellvizio™ system to the gingival tissue without any surgical incision. Evans blue emission intensity was significantly elevated in gingiva of periodontitis lesions, but not control non-ligature placed gingiva, indicating that this technology can be used as a potential minimally invasive diagnostic tool to monitor the level of inflammation at the periodontal disease site.

Upper gastrointestinal hemorrhage from bleeding peptic ulcer is sometimes difficult to treat by conventional endoscopic methods. Recently, monopolar electrocoagulation using a soft-coagulation system and hemostatic forceps (soft coagulation) has been used to prevent bleeding during endoscopic submucosal dissection. The aim of this study was to assess the safety and efficacy of soft coagulation in the treatment of bleeding peptic ulcer. A total of 39 patients with peptic ulcers were treated using soft coagulation at our hospital between January 2005 and March 2010. Emergency treatment employed an ERBE soft-mode coagulation system using hemostatic forceps. Second-look endoscopy was performed to evaluate the efficacy of prior therapy. Initial hemostasis was defined as accomplished by soft coagulation, with or without other endoscopic therapy prior to soft coagulation. The rate of initial hemostasis, rebleeding, and ultimate hemostasis were retrospectively analyzed. The study subjects were 31 men and 8 women with a mean age of 68.3±13.7 years, with 29 gastric ulcers and 10 duodenal ulcers. Initial hemostasis was achieved in 37 patients (95%). During follow-up, bleeding recurred in two patients, who were retreated with soft coagulation. The monopolar soft coagulation is feasible and safe for treating bleeding peptic ulcers.

The high frequency of complications accompanying endoscopic submucosal dissection (ESD) and its complex processes suggest that the process requires improvement. The objective of the present study was to investigate the feasibility of an innovated splash-needle for ESD. An animal feasibility study with a living pig was conducted. Six resections per portion (esophagus and upper, middle, and lower thirds of the stomach) in a total of 24 resections were carried out by using an original splash-needle or an innovated splash-needle. Major innovations were a thicker part in the middle of the knife and a metal plate on the tip of the sheath to obtain more coagulation ability. Injection solution in the submucosal layer was also changed due to possible influence on the outcomes. Main outcome measurements were entire procedure time, cutting speed, and frequency of bleeding during ESD. All the 24 resections were completed without complications. Among the obtained data, only mean cutting speeds were significantly influenced by location of the simulated lesion, which revealed that ESD at the upper third was significantly quicker than that at the lower third (P = 0.01), and ESD at the esophagus was significantly slower than that at the three parts of the stomach (P < 0.01). There was no significant difference between the different knives in each variable. The innovated splash-needle will be feasible for human use, although the safety and advantages in clinical settings must be elucidated by proper comparative studies with existing knives in humans. © 2012 The Authors.

Endoscopy of the upper respiratory tract during treadmill exercise: a clinical study of 100 horses.
Kannegieter, N J; Dore, M L
1995-03-01
Endoscopy of the upper respiratory tract was performed in 100 horses during high speed treadmill exercise. Reasons for endoscopy were a history of an abnormal noise during exercise in 75 horses, poor performance in 17 horses and to evaluate the results of upper respiratory tract surgery in 8 horses. Of the 75 horses with a history of an abnormal noise during exercise the cause was determined in 67 (89%). Endoscopic abnormalities were detected at rest in 40 of these 75 horses (53%). In these 40 horses, a similar diagnosis as to the cause of the abnormal noise was made at rest and during exercise on the treadmill in 19 cases, while in the remaining 21 the endoscopic findings during exercise varied from that seen at rest. This included 3 horses in which a diagnosis was made at rest but no abnormalities were detected during exercise. Some of the findings during treadmill endoscopy included laryngeal dysfunction, grades 3, 4 and 5 (22 cases), dorsal displacement of the soft palate (20), epiglottic entrapment (8), epiglottic flutter (4), aryepiglottic fold flutter (4), pharyngeal collapse (3), arytenoiditis (3), vocal cord flutter (3), false nostril noise (2), pharyngeal lymphoid hyperplasia (2), soft palate haemorrhage (1) and positional arytenoid collapse (1). More than one abnormality was observed during exercise in 7 horses. A complete and correct diagnosis based on the resting endoscopy findings alone was made in 19 (25%) of these 75 cases. In the 17 horses examined because of poor performance, no abnormalities were detected during treadmill endoscopy that were not evident at rest.(ABSTRACT TRUNCATED AT 250 WORDS)

Lingual thyroglossal duct cysts (LTGDCs) are very rare and liable to be misdiagnosed as simple vallecular or mucus retention cysts. We recognized the importance of complete resection by means of the Sistrunk operation and applied the revised surgical technique to the treatment of LTGDCs. The aim of this study was to evaluate the results of surgical management of LTGDCs from the author's series and analyze its utility. Twelve patients, 10 male and 2 female, who were diagnosed with LTGDCs between January 2007 and December 2012, underwent endoscopic radical resection with microdissection electrodes. All cases were evaluated by enhanced CT and flexible laryngoscope before surgery. We reviewed the collected data including presentation, CT findings, surgical techniques, postoperative complication, and recurrence. Most adult LTGDCs presented with foreign body sensation, while one infant presented acute upper airway obstruction. All cysts abutted on the hyoid bone and were located at the midline of the posterior tongue. Endoscopic radical resection with microdissection electrodes was possible by dissecting hyoid periosteum without significant morbidity. All patients excluding 1 infant were not intubated electively overnight and went home the following morning. All patients showed no evidence of recurrence during follow-up. We found that the diagnosis of LTGDCs must be based on the anatomic relationship with the hyoid bone by enhanced sagittal neck CT. Endoscopic radical resection with microdissection electrodes can be recommended for reducing recurrence and morbidity by dissecting the hyoid perichondrium in the treatment of LTGDCs.

Two hundred patients affected by liver cirrhosis and oesophageal varices were studied in 9 Gastrointestinal Units in Lombardy (Northern Italy) in order to assess factors possibly related to variceal bleeding. Only patients without any previous episode of gastrointestinal bleeding were included in the prospective evaluation. For each patient demographic data, aetiology of cirrhosis, various clinical and biochemical parameters able to group patients into the three Child-Pugh Classes, endoscopic items for calculation of Beppu's and of NIEC prognostic scores were recorded on computerized cards. Patients were regularly interviewed every three months for one year and underwent an upper gastrointestinal endoscopy at enrollment, after six months and in case of bleeding. Within the twelve-month follow-up period, 29 out of the 200 patients (14%) bled and 52 out of 200 died (26%). In 16 of the 52 patients who died (59% of bleeding patients) death was directly related to gastrointestinal bleeding. Bleeding from oesophageal varices was endoscopically proven in 19/29 patients, in another 9 bleeding was classified as from unknown source and in one patient a bleeding gastric ulcer was diagnosed. Univariate analysis of all the recorded clinical, biochemical and endoscopic parameters, performed by Chi-square method and Fisher exact test showed that the presence of RWM (p < 0.001) was the only factor significantly associated to variceal bleeding within one year. Relationship between size of varices and bleeding was very close to the statistical significance but did not achieve it (p = 0.058).

Ureteral stents and ureteral catheters externalized through the urethra are not ideal solutions to manage complicated upper urinary tract fistulae. We sought an effective method of drainage, minimally invasive, reproducible allowing a rapid patient's discharge. Between November 2013 and February 2015, an ureteral stent was exteriorized in trans-vesico-parietal by an endoscopic and percutaneous access in patients with complicated upper urinary tract fistulae. Monitoring of tolerance, complications and urinary fistula healing was performed. Nine consecutive patients had an ureteral stent exteriorized in trans-vesico-parietal to manage complicated upper urinary tract fistulae. There was no failure in introducing the catheter, or postoperative complication. Catheters were left in place on average 36.1days (24-55). The patients were able to return home with the catheter in place in 77.8% of cases. The tolerance of the catheter was good. All fistulae were able to be treated conservatively at the end of the drainage period. Trans-vesico-parietal ureteral catheters enable efficient and reproducible conservative treatment of upper tract urinary fistulae regardless of their cause. 5. Copyright © 2016 Elsevier Masson SAS.

The upper airway is a complex and intricate system responsible for respiration, phonation, and deglutition. Obstruction of the upper airways afflicts an estimated 12-18 million Americans. Pharyngeal size and shape are important factors in the pathogenesis of airway obstructions. In addition, nocturnal loss in pharyngeal muscular tone combined with high pharyngeal resistance can lead to collapse of the airway and periodic partial or complete upper airway obstruction. Anatomical optical coherence tomography (OCT) has the potential to provide high-speed three-dimensional tomographic images of the airway lumen without the use of ionizing radiation. In this chapter we describe the methods behind endoscopic OCT imaging and processing to generate full three dimensional anatomical models of the human airway which can be used in conjunction with numerical simulation methods to assess areas of airway obstruction. Combining this structural information with flow dynamic simulations, we can better estimate the site and causes of airway obstruction and better select and design surgery for patients with obstructive sleep apnea.

Endoscopic treatment of upper-tract transitional-cell carcinoma (TCC) is well established. Nevertheless, many patients still required major ablative surgery. We have applied our experience with laparoscopic nephrectomy to the performance of laparoscopic nephroureterectomy in order to make the management of upper-tract TCC entirely minimally invasive. Since 1993, we have performed 22 laparoscopic nephroureterectomies for upper-tract TCC. Initially, we excluded patients with tumors below the pelvic brim, but we now offer a trial of laparoscopy to all patients. We describe the evolution of our technique, which involves resecting the ureteral orifice prior to laparoscopic dissection of the kidney and ureter. We have had to convert three cases to open surgery, one each for bleeding, failure to progress, and unappreciated tumor extent. Operative times averaged 156 minutes, which compares well with contemporary times for open nephroureterectomy. Complication rates, transfusion requirements, and length of stay, although higher than those of laparoscopic nephrectomy, were all reduced in comparison with open nephroureterectomy.

Acute upper gastrointestinal (GI) bleeding is a common condition in the UK with 50-70,000 admissions per year. In 20% of cases no cause can be found on endoscopy. Here, we present the case of a young female patient who was admitted on three occasions with large volume haematemesis and bleeding from other sites. She was extensively investigated and underwent multiple endoscopic procedures. She was eventually diagnosed with factitious disorder after concerns were raised about the inconsistent nature of her presentations. She was found to be venesecting herself from her intravenous cannula, and ingesting the blood to simulate upper GI bleeding. This is a rare cause of 'haematemesis' but perhaps not as rare as is thought.

Adenocarcinoma of the distal esophagus, gastric cardia, and upper gastric third are grouped in type I-III by the Siewert classification. This classification is based on the endoscopic localisation of the tumor center, and is the most important diagnostic tool to group these tumors. On a molecular level, there is currently no marker that would allow to differentiate the three different types. Furthermore, the Siewert classification was not uniformly used in the recent literature, making interpretation and generalization of these results difficult. However, several potential targets have been identified that may help to separate these tumors by molecular markers, and are summarized in this chapter.

We present a case of intramural duodenal hematoma as a complication of endoscopic therapy for a bleeding duodenal ulcer in an adult patient with no evidence of other pathologies. A 18-year-old man was admitted in emergency room with gastrointestinal bleeding manifested by melena. Previous medical history revealed that he had endoscopic sclerotherapy for bleeding duodenal ulcer 5 months before. Endoscopy revealed a Forrest 2a ulcer in the duodenal bulb and sclerotherapy was performed by injecting 10 ml of 0.2% epinephrine and 20 ml of NaCl 0.9% solution. Upper occlusion’s signs appeared 36 hours after the procedure. The hematoma, that was identified by endoscopy and confirmed by MRI and CT scan of the abdomen, caused transient duodenal obstruction. Combined conservative management with nasogastric tube and total parenteral nutrition resulted in reduction of obstructive symptoms within 4 weeks. PMID:25827667

Foreign bodies and caustic lesions.
Dray, Xavier; Cattan, Pierre
2013-10-01
Foreign body ingestions, food bolus impactions, and caustic agent injuries are frequent but specific situations. Although most foreign bodies will naturally pass through the digestive tract, practitioners should recognize specific situations were endoscopic management is required. In such cases, timing and adequate equipment are critical. Endoscopic treatment is successful in about 95% of patients. Severe complications (including oesophageal perforations) are rare. Underlying diseases (including eosinophilic oesophagitis) must be investigated after food bolus impaction. Accidental or suicidal ingestion of corrosive agents may result in severe upper gastrointestinal tract injuries requiring a multidisciplinary approach including gastroenterologists, surgeons, otorhynolaryngologists, anaesthesiologists and psychiatrists. Treatment includes conservative management of patients with mild injuries, while patients with severe injuries undergo emergency surgical exploration. At distance of the ingestion episode, oesophageal reconstruction is required in patients who underwent oesophageal resection and in patients who developed oesophageal strictures that failed dilatation.

Cryptococcal nasopharyngeal polypoid mass in a cat
Javard, Romain; Alexander, Kate; Girard, Christiane; Dunn, Marilyn
2015-01-01
Case summary An indoor 9-year-old castrated male domestic cat was referred with a 4 month history of increased upper airway noise. Computed tomography revealed a nasopharyngeal polypoid mass, which was removed endoscopically with basket forceps. Histopathology was compatible with a polypoid granulomatous pharyngitis with Cryptococcus-like organisms. This was supported by a positive serum latex cryptococcal antigen agglutination test (LCAT). Minimal inflammation of the nasal tissue was noted on histopathology, with no evidence of fungus. Following endoscopic removal of the mass, the patient was treated with systemic antifungal medication (itraconazole). One year after diagnosis, the LCAT titer was negative and the cat remained free of clinical signs. Relevance and novel information This case report emphasizes the importance of considering Cryptococcus species as a potential etiology in cats presented with signs of nasopharyngeal obstruction with an isolated nasopharyngeal polypoid mass, even if kept indoors.

History, instrumentation, and techniques of flexible endoscopic laser surgery in horses.
Blikslager, A T; Tate, L P
2000-08-01
There are clearly a number of applications for which flexible endoscopic laser surgery has become the state of the art in equine surgery, and the Nd:YAG laser seems to be the most versatile instrument for this type of surgery. Nevertheless, it is critical to understand the advantages and disadvantages of each laser technique. For example, the Nd:YAG laser used in a noncontact fashion seems to be superior when ablation of tissue is required such as treatment of upper airway masses. Conversely, contact Nd:YAG laser techniques have proven themselves to be superior when more precise cutting is advantageous such as treatment of epiglottic entrapment. Ultimately, it seems that a range of lasers is necessary to ensure selection of the most appropriate technique, adding significantly to the expense of equipment but improving the outcome for a range of equine diseases.

Abstract Rationale: The development of postoperative bronchopleural fistula (BPF) remains a challenge in thoracic surgery. We herein report a case of BPF successfully treated with endoscopic bronchial occlusion under computed tomography (CT) fluoroscopy and virtual bronchoscopic navigation (VBN). Patient concerns: A 63-year-old man underwent right upper lobectomy with concomitant S6a subsegmentectomy for lung adenocarcinoma. On postoperative day 24, he complained of shaking chills with high fever. Diagnoses: BPF with subsequent pneumonia and empyema. Interventions: Despite aggressive surgical interventions for the BPF, air leakage persisted postoperatively. On days 26 and 34 after the final operation, endobronchial occlusions were performed under CT fluoroscopy and VBN. Outcomes: The air leaks greatly decreased and the patient was discharged. Lessons: CT fluoroscopy and VBN can be useful techniques for endobronchial occlusion in the treatment of BPF. PMID:29443771

Esophageal thermal injury caused by food has been reported to occur mostly after drinking hot liquid food, and is known to produce alternating white and red linear mucosal bands. In addition, thermal injury caused by ingestion of hot solid foods is documented to be a cause of esophageal ulcers or pseudomembranes. From January 2006 to August 2012, five patients with suspected esophageal thermal injury underwent esophagogastroduodenoscopy with biopsy. A "candy-cane" appearance was observed in one case, pseudomembrane was observed in two cases, an esophageal ulcer was observed in one case, and a friable and edematous mucosa was noted in one case. We believe that the endoscopic findings of esophageal thermal injury depend on the following factors: causative materials, amount of food consumed, exposure period, and time to endoscopy after the incident. Therefore, physicians who encounter patients with suspected esophageal thermal injury should carefully take the patient's history considering these factors.

Zheng, Dongtian; Tan, Haishu; Zhou, Fuqiang
2017-03-01
An endoscopic imaging system of hyper long pipeline is designed to acquire the inner surface image in advance for the hyper long pipeline detects measurement. The system consists of structured light sensors, pipe robots and control system. The pipe robot is in the form of wheel structure, with the sensor which is at the front of the vehicle body. The control system is at the tail of the vehicle body in the form of upper and lower computer. The sensor can be translated and scanned in three steps: walking, lifting and scanning, then the inner surface image can be acquired at a plurality of positions and different angles. The results of imaging experiments show that the system's transmission distance is longer, the acquisition angle is more diverse and the result is more comprehensive than the traditional imaging system, which lays an important foundation for later inner surface vision measurement.
Chronic pancreatitis with multiple pseudocysts and pancreatic panniculitis: A case report.
Gu, Yuqing; Qian, Zhuyin
2018-06-01
Pancreatic pseudocyst can present single or multiple, inside or outside the pancreas. Pancreatic panniculitis is a rare skin lesion in pancreatic disease patients. The purpose of this study is to report a case of chronic pancreatitis coexisting with multiple pseudocysts and pancreatic panniculitis. A 46-year-old man with chronic pancreatitis presented multiple small cystic lesions inside the head of the pancreas and two large cystic lesions adjacent to the tail of the pancreas. The patient also developed subcutaneous nodules involving upper and lower limbs, hands, and lower abdomen bilaterally. The patient was diagnosed with pancreatic pseudocyst and pancreatic panniculitis resulted from chronic pancreatitis. Bile duct stent and pancreatic duct stent placement was performed endoscopicly. Panniculitis faded three weeks later and the pancreatic pseudocysts disappeared six weeks later. Clinicians should be aware of the manifestation of multiple pancreatic pseudocyst and pancreatic panniculitis, and endoscopic transpapillary drainage may be a effective way in this scenario.

Gastrointestinal bleeding is one of the most common indications for urgent endoscopy in the pediatric setting. The majority of these procedures are performed for control of variceal bleeding, with few performed for nonvariceal upper gastrointestinal (NVUGI) bleeding. The data on therapeutic endoscopy for NVUGI are sparse. The aims of our study were to review our experience with NVUGI bleeding, describe technical aspects and outcomes of therapeutic endoscopy, and determine gastroenterology fellows' training opportunities according to the national training guidelines. We performed a retrospective review of endoscopy database (Endoworks, Olympus Inc, Center Valley, PA) from January 2009 to December 2014. The search used the following keywords: bleeding, hematemesis, melena, injection, epinephrine, cautery, clip, and argon plasma coagulation. The collected data included demographics, description of bleeding lesion and medical/endoscopic therapy, rate of rebleeding, relevant laboratories, physical examination, and need for transfusion and surgery. The study was approved by the institutional review board. During the study period 12,737 upper endoscopies (esophagogastroduodenoscopies) were performed. A total of 15 patients underwent 17 esophagogastroduodenoscopies that required therapeutic intervention to control bleeding (1:750 procedures). The mean ± standard deviation (median) age of patients who required endoscopic intervention was 11.6 ± 6.0 years (14.0 years). Seven out of 17 patients received dual therapy to control the bleeding lesions. All but 3 patients received medical therapy with intravenous proton pump inhibitor, and 3 received octreotide infusions. Six of the patients experienced rebleeding (40%), with 4 out of 6 initially only receiving single modality therapy. Two of these patients eventually required surgical intervention to control bleeding and both patients presented with bleeding duodenal ulcers. There were no cases of aspiration, perforation, or deaths. There were a total of 24 fellows trained in our program during the study period. Less than 1 therapeutic endoscopy per fellow for NVUGI bleeding was performed. NVUGI bleeding requiring therapeutic endoscopic intervention is rare in pediatrics. A high rate (40%) of rebleeding was noted with a large proportion (66%) of patients receiving single modality therapy. Two patients required surgical intervention to control bleeding and both presented with bleeding duodenal ulcers. An insufficient number of therapeutic procedures is available for adequate fellow training requiring supplemental simulator and hands-on animal model, or adult endoscopy unit training.

This study compares the effects of two different benzodiazepines used for conscious sedation during combined upper gastrointestinal endoscopy (EGD) and colonoscopy. Subjects were assessed for their degree of analgesia and amnesia for the procedure, prior experience with endoscopy, and willingness to undergo another similar procedure should such be necessary. The patients were randomized single blind to receive either midazolam or diazepam for their preprocedure sedation. The amount of preprocedure sedation utilized was determined by titration of the dose to achieve slurring of speech. Prior to receiving either agent, the subjects were shown a standard card containing pictures of 10 common objects, were asked to name and remember them, and were told they would be "quizzed" (at 30 min and 24 hr) after being sedated for their recollection as to the objects pictured on the card. Each subject filled out a questionnaire addressing their perceived discomfort during the endoscopic procedure and their memory of the procedure 24 hr after the procedure. Sixty-three percent of the midazolam-sedated subjects reported total amnesia for their colonoscopy vs 20% of diazepam-sedated patients (P less than 0.001). Fifty-three percent of midazolam-sedated patients reported total amnesia of their upper gastrointestinal endoscopy vs only 23% of diazepam-sedated subjects (P less than 0.05). The midazolam-sedated subjects reported experiencing less pain with both upper gastrointestinal endoscopy (P less than 0.05) and colonoscopy (P less than 0.001) than did the diazepam-sedated group. Most importantly, the midazolam group was more willing to undergo another similar endoscopic procedure should they be asked to do so by their physician (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

To review the indications, procedures, complications, and related treatments of double pigtail stent (DPS) placement as an adjunct for some types of endoscopic and open urologic surgery. From July 1998 to December 2006, 2413 patients aged 8 to 81 years underwent stent placement (2685 total placements). The indications consisted of ureteroscopic lithotripsy (1984 cases), percutaneous nephrolithotomy (329 cases), ureteral incision to remove calculi (71 cases), extracorporeal shockwave lithotripsy for upper urinary tract calculi (145 cases), ureteropelvic junction obstruction (31 cases), ureterocystoneostomy (29 cases), benign ureteral stenosis (52 cases), extrinsic ureteral stenosis (16 cases), and iatrogenic ureteral trauma (28 cases). DPSs were inserted into the ureter by cystoscopy (115 stents), ureteroscopy (2052 stents), percutaneous nephrostomy (393 stents), or open surgery (125 stents), and were kept inside the body for 28 +/- 1.7 days (range 1-193 days). The mean follow-up period was 31 +/- 1.9 days (range 1-123 days). Three hundred sixty-five patients (19.6%) experienced one or more problems during the stenting procedure. The main complications were gross hematuria (385 cases), pain (101 cases), bladder irritation (105 cases), high fever (6 cases), encrustation (53 cases), stent migration (42 cases), and stenosis or restenosis (51 cases). Most of the complications were mild and tolerable, and all were immediately treated appropriately. However, 60 stents had to be removed: 29 for gross hematuria, 18 for pain, 7 for bladder irritation, and 6 for high fever. DPS is a safe and useful adjunct for both endoscopic and open procedures to treat upper urinary tract diseases. Most of the complications of DPS placement can be well managed.

Ureteral stents are employed in the upper and urethral stents in the lower urinary tract for restitution or maintenance of urinary drainage. Placement of ureteral stents is indicated as an adjuvant measure prior to extracorporal disintegration (ESWL) of large kidney stones to insure urinary drainage and enhance expulsion of fragments and disintegrate. Also, obstruction by very small urinary tract stones that are not treatable by ESWL because they cannot be localized can be relieved by placement of a double-J-stent with immediate elimination of colic. If the cause of urinary tract obstruction is external ureteral compression (retroperitoneal mass), placement of a special tumor stent is one possibility. This, however, has the danger of becoming reobstructed with detritus and blockage of the drainage holes in the stent. In these cases the essential drainage along the stent is blocked by the mass. Therefore, a percutaneous nephrostomy providing direct drainage is easier to control and preferable. Obstructive pyelonephritis is an absolute indication for drainage of the upper urinary tract with a double-J-stent, or even better by percutaneous nephrostomy. If pyeloureteral or ureteral stenoses of the upper urinary tract are opened endoscopically, then the double-J-stent serves to maintain and insure drainage until the new lumen is reepithelialized. In patients with prostatic hyperplasia who no longer respond to medical treatment and who are not candidates for more invasive surgical treatment, a stent can be placed in the prostatic urethra under local anesthesia as a last resort. This procedure is seldom used but, in view of the satisfactory long-term results, it provides a true alternative to bladder drainage by transurethral catheter or percutaneous cystostomy. The same stents may be used in the bulbar urethra to reduce restricture rates following endoscopic treatment of strictures.

Patients with upper gastrointestinal bleeding (UGIB) require an early, tailored approach best guided by knowledge of the bleeding lesion, especially a variceal versus a nonvariceal source. To identify, by investigating a large national registry, variables that would be predictive of a variceal origin of UGIB using clinical parameters before endoscopic evaluation. A retrospective study was conducted in 21 Canadian hospitals during the period from January 2004 until the end of May 2005. Consecutive charts for hospitalized patients with a primary or secondary discharge diagnosis of UGIB were reviewed. Data regarding demographics, including historical, physical examination, initial laboratory investigations, endoscopic and pharmacological therapies administered, as well as clinical outcomes, were collected. Multivariable logistic regression modelling was performed to identify clinical predictors of a variceal source of bleeding. The patient population included 2020 patients (mean [± SD] age 66.3±16.4 years; 38.4% female). Overall, 215 (10.6%) were found to be bleeding from upper gastrointestinal varices. Among 26 patient characteristics, variables predicting a variceal source of bleeding included history of liver disease (OR 6.36 [95% CI 3.59 to 11.3]), excessive alcohol use (OR 2.28 [95% CI 1.37 to 3.77]), hematemesis (OR 2.65 [95% CI 1.61 to 4.36]), hematochezia (OR 3.02 [95% CI 1.46 to 6.22]) and stigmata of chronic liver disease (OR 2.49 [95% CI 1.46 to 4.25]). Patients treated with antithrombotic therapy were more likely to experience other causes of hemorrhage (OR 0.44 [95% CI 0.35 to 0.78]). Presenting historical and physical examination data, and initial laboratory tests carry significant predictive ability in discriminating variceal versus nonvariceal sources of bleeding.

Conventional endoscopy for self-expandable metallic stent (SEMS) placement may be technically limited in long and tortuous strictures. Therefore, we analyzed the feasibility, safety and usefulness of ultrathin endoscopy (UTE)-guided SEMS placement. This study involved 24 patients with upper gastrointestinal obstruction and unsuccessful initial attempts to place SEMS using conventional endoscopy. After completely passing a UTE across the stricture, the UTE was withdrawn, leaving a guidewire placed via the working channel. Through-the-scope SEMS placement was done using a conventional endoscope inserted along the guidewire. The primary endpoints were assessed by technical/clinical success and stent patency duration. Stents were successfully placed at target locations in all but one case with a long tortuous stricture, with 95.8% (23/24) technical success. One week after stent placement, mean gastricoutlet obstruction score improved significantly from baseline (1.74 ± 0.62 and 0.33 ± 0.48, respectively; P < 0.001). Stent migration, restenosis, and fracture occurred in four (17.4%), six (26.1%), and one (4.3%) of 23 stents, respectively. Median stent patency duration was 79 days. Mean stent patency was significantly longer in patients who received palliative chemotherapy than in those who did not (122.9 ± 11.0 and 38.3 ± 4.6, respectively; P < 0.001). UTE guidance SEMS delivery can be a feasible and safe rescue treatment method for malignant upper gastrointestinal obstruction in cases of failed attempts to place SEMS using conventional endoscopy. Our result warrants a further study to define the efficacy of this method in difficult SEMS placement cases. © 2013 The Authors.

Chordoma is a rare bony malignancy known to have a high rate of local recurrence after surgery. The best treatment paradigm is still being evaluated. We report our experience and review the literature. We emphasize on the difference between endoscopic and open craniotomy in regard to the anatomical compartment harboring the tumor, the limitations of the approaches and the rate of surgical resection. We retrospectively collected all patients with skull-base chordomas operated on between 2004 and 2014. Detailed radiological description of the compartments being occupied by the tumor and the degree of surgical resection is discussed. Eighteen patients were operated on in our facility for skull-base chordoma. Seventeen endoscopic surgeries were done in 15 patients, and 7 craniotomies were done in 5 patients. The mean age was 48.9 years (±19.8 years). When reviewing the anatomical compartments, we found that the most common were the upper clivus (95.6%) and lower clivus (58.3%), left cavernous sinus (66.7%) and petrous apex (∼60%). Most of the patients had intradural tumor involvement (70.8%). In all craniotomy cases, there was residual tumor in multiple compartments. In the endoscopic cases, the most difficult compartments for total resection were the lower clivus, and lateral extensions to the petrous apex or cavernous sinus. Our experience shows that the endoscopic approach is a good option for midline tumors without significant lateral extension. In cases with very lateral or lower extensions, additional approaches should be added trying to achieve complete resection.

Peptic ulcer represents the most common cause of upper gastrointestinal bleeding. Endoscopic therapy can reduce the risks of rebleeding, continued bleeding, need for surgery, and mortality. The objective of this review is to compare the different modalities of endoscopic therapy. Studies were identified by searching electronic databases MEDLINE, Embase, Cochrane, LILACS, DARE, and CINAHL. We selected randomized clinical trials that assessed contemporary endoscopic hemostatic techniques. The outcomes evaluated were: initial hemostasis, rebleeding rate, need for surgery, and mortality. The possibility of publication bias was evaluated by funnel plots. An additional analysis was made, including only the higher-quality trials. Twenty-eight trials involving 2988 patients were evaluated. Injection therapy alone was inferior to injection therapy with hemoclip and with thermal coagulation when evaluating rebleeding and the need for emergency surgery. Hemoclip was superior to injection therapy in terms of rebleeding; there were no statistically significant differences between hemoclip alone and hemoclip with injection therapy. There was considerable heterogeneity in the comparisons between hemoclip and thermal coagulation. There were no statistically significant differences between thermal coagulation and injection therapy, though their combination was superior, in terms of rebleeding, to thermal coagulation alone. Injection therapy should not be used alone. Hemoclip is superior to injection therapy, and combining hemoclip with an injectate does not improve hemostatic efficacy above hemoclip alone. Thermal coagulation has similar efficacy as injection therapy; combining these appears to be superior to thermal coagulation alone. Therefore, we recommend the application of hemoclips or the combined use of injection therapy with thermal coagulation for the treatment of peptic ulcer bleeding.

To compare endoscopic findings of the upper portion of the respiratory tract in Thoroughbred yearlings with their subsequent race records to determine whether subjective assessment of airway function may be used as a predictor of future racing performance. Retrospective study. 427 Thoroughbred yearlings. Endoscopic examination findings were obtained from the medical records and the videoendoscopic repository of the Keeneland 1996 September yearling sales. Racing records were requested for the yearlings through the end of their 4-year-old racing season (1997-2000). Twenty-nine measures of racing performance were correlated with endoscopic findings. Subjective arytenoid cartilage movement grades were determined, using a 4-point grading scale (grade 1 = symmetrical synchronous abduction of the arytenoid cartilages; grade 4 = no substantial movement of the left arytenoid cartilage). Of the 427 Thoroughbred yearlings included in this study, 364 established race records, and 63 did not. Opinions regarding suitability for purchase, meeting conditions of the sale, and the presence of epiglottic abnormalities had no significant association with racing performance. Arytenoid cartilage movement grades were significantly associated with many of the dependent variables. However, palatine abnormalities were not predictive of inferior racing performance. Thoroughbred yearlings with grade-1 and -2 arytenoid cartilage movements had significantly better racing performance as adults, compared with yearlings with grade-3 arytenoid cartilage movements. In contrast, epiglottic and palatine abnormalities were not predictive of inferior racing performance. Therefore, evaluation of laryngeal function, but not epiglottic or palatine abnormalities, using the 4-point grading system, should be the major factor in developing recommendations for prospective buyers.

Gastrointestinal (GI) tumor bleeding can vary from occult bleeding to massive hemorrhage and can be the presenting sign of malignancy. Our primary aims were to: (1) characterize the natural history, treatment, and outcomes in patients with GI tumor bleeding and (2) compare and contrast bleeding in upper GI (UGI)/small bowel (SB) and lower GI malignancies. Patients with endoscopically confirmed tumor bleeding were identified through search of consecutive electronic medical records: Bleeding was determined by the presence of melena, hematochezia, hematemesis, or fecal occult blood. Comprehensive clinical and management data were abstracted. A total of 354 patients with GI tumors were identified: 71 had tumor bleeding (42 UGI/SB and 29 colonic). GI bleeding was the initial presenting symptom of malignancy in 55/71 (77%) of patients; 26/71 patients had widely metastatic disease at presentation. Further, 15 of 26 patients with metastatic disease presented with GI bleeding. Visible bleeding was present in 14/42 (33%) and 4/29 (14%) of UGI/SB and colonic tumors, respectively. Endoscopic hemostasis was attempted in 10 patients, and although initial control was successful in all, bleeding recurred in all of these patients. The most common endoscopic lesion was clean-based tumor ulceration. Overall mortality at 1 year was 57% for esophageal/gastric, 14% for SB, and 33% for colonic tumors. When patients with GI malignancy present with GI bleeding, it is often the index symptom. Initial endoscopic hemostasis is often successful, but rebleeding is typical. Esophageal and gastric tumors carry the poorest prognosis, with a high 1-year mortality rate.

Background Peptic ulcer bleeding (PUB) is the main cause of non-variceal upper gastrointestinal bleeding (UGIB). Endoscopic treatment and acid suppression with proton-pump inhibitors (PPIs) are most important in the management of PUB and these treatments have reduced mortality. However, elderly patients sometimes have a poor prognostic outcome due to severe comorbidities. Methods A retrospective study was performed on 504 cases with acute non-variceal UGIB who were examined in our hospital, in order to reveal the risk factor of a poor outcome in elderly patients. Results Two hundred and thirty-four cases needed hemostasis; 11 cases had unsuccessful endoscopic treatments; 31 cases had re-bleeding after endoscopic hemostasis. Forty-three cases died within 30 days after the initial urgent endoscopy, but only seven cases died from bleeding. Elderly patients aged over 65 years had more severe comorbidities, and were prescribed non-steroidal anti-inflammatory drugs (NSAIDs), antiplatelet agents and/or anticoagulation agents, more frequently, compared with non-elderly patients. The significant risk factor of needing hemostatic therapy was the taking of two or more NSAIDs, antiplatelet agents and/or anticoagulation agents. The most important risk of a poor outcome in elderly patients was various kinds of severe comorbidities. And so, it is important to predict such an outcome in these cases. AIMS65 is a simple and relatively useful scoring system that predicts the risk of a poor outcome in UGIB. High-score patients via AIMS65 were associated with a high mortality rate because of death from comorbidities. Conclusions The elderly patients in whom were prescribed two or more NSAIDs, antiplatelet agents and/or anticoagulation agents, should have UGIB prevented using a PPI. The most significant risk of a poor outcome in elderly patients was severe comorbidities. We recommend that elderly patients with UGIB should be estimated as having a poor outcome as soon as possible via the risk scoring system AIMS65. PMID:28616396

ACG Clinical Guideline: Diagnosis and Management of Small Bowel Bleeding.
Gerson, Lauren B; Fidler, Jeff L; Cave, David R; Leighton, Jonathan A
2015-09-01
Bleeding from the small intestine remains a relatively uncommon event, accounting for ~5-10% of all patients presenting with gastrointestinal (GI) bleeding. Given advances in small bowel imaging with video capsule endoscopy (VCE), deep enteroscopy, and radiographic imaging, the cause of bleeding in the small bowel can now be identified in most patients. The term small bowel bleeding is therefore proposed as a replacement for the previous classification of obscure GI bleeding (OGIB). We recommend that the term OGIB should be reserved for patients in whom a source of bleeding cannot be identified anywhere in the GI tract. A source of small bowel bleeding should be considered in patients with GI bleeding after performance of a normal upper and lower endoscopic examination. Second-look examinations using upper endoscopy, push enteroscopy, and/or colonoscopy can be performed if indicated before small bowel evaluation. VCE should be considered a first-line procedure for small bowel investigation. Any method of deep enteroscopy can be used when endoscopic evaluation and therapy are required. VCE should be performed before deep enteroscopy if there is no contraindication. Computed tomographic enterography should be performed in patients with suspected obstruction before VCE or after negative VCE examinations. When there is acute overt hemorrhage in the unstable patient, angiography should be performed emergently. In patients with occult hemorrhage or stable patients with active overt bleeding, multiphasic computed tomography should be performed after VCE or CTE to identify the source of bleeding and to guide further management. If a source of bleeding is identified in the small bowel that is associated with significant ongoing anemia and/or active bleeding, the patient should be managed with endoscopic therapy. Conservative management is recommended for patients without a source found after small bowel investigation, whereas repeat diagnostic investigations are recommended for patients with initial negative small bowel evaluations and ongoing overt or occult bleeding.

The infraorbital nerve (ION) is a terminal branch of the maxillary nerve (V2) providing sensory innervation to the malar skin. It is sometimes necessary to sacrifice the ION and its branches to obtain adequate maxillary sinus exposure for radical resection of sinonasal tumors. Consequently, patients suffer temporary or permanent paresthesia, hypoestesthia, and neuralgia of the face. We describe an innovative technique used for preservation of the ION while removing the anterior, superior, and lateral walls of the maxillary sinus through a medial endoscopic transnasal maxillectomy. All patients who underwent transnasal endoscopic maxillectomy with ION transposition in our institute were retrospectively reviewed. Two patients were identified who had been treated for sinonasal cancers using this approach. No major complications were observed. Transient loss of ION function was observed with complete recovery of skin sensory perception within 6 months of surgery. One patient referred to a mild permanent anesthesia of the upper incisors. No diplopia or enophthalmos were encountered in any of the patients. The ION transposition is useful for selected cases of benign and malignant sinonasal tumors that do not infiltrate the ION itself but involve the surrounding portion of the maxillary sinus. Anatomic preservation of the ION seems to be beneficial to the postoperative quality of life of such patients. © 2016 ARS-AAOA, LLC.

Depth resolved and en face OCT visualization in vivo may have important clinical applications in endoscopy. We demonstrate a high speed, two-dimensional (2D) distal scanning capsule with a micromotor for fast rotary scanning and a pneumatic actuator for precision longitudinal scanning. Longitudinal position measurement and image registration were performed by optical tracking of the pneumatic scanner. The 2D scanning device enables high resolution imaging over a small field of view and is suitable for OCT as well as other scanning microscopies. Large field of view imaging for screening or surveillance applications can also be achieved by proximally pulling back or advancing the capsule while scanning the distal high-speed micromotor. Circumferential en face OCT was demonstrated in living swine at 250 Hz frame rate and 1 MHz A-scan rate using a MEMS tunable VCSEL light source at 1300 nm. Cross-sectional and en face OCT views of the upper and lower gastrointestinal tract were generated with precision distal pneumatic longitudinal actuation as well as proximal manual longitudinal actuation. These devices could enable clinical studies either as an adjunct to endoscopy, attached to an endoscope, or as a swallowed tethered capsule for non-endoscopic imaging without sedation. The combination of ultrahigh speed imaging and distal scanning capsule technology could enable both screening and surveillance applications. PMID:25909001

Post-intubation tracheal laceration (PITL) is a rare and potential life-threatening condition requiring prompt diagnosis and treatment. A conservative treatment is indicated in patients with laceration <2 cm in length while surgery is the treatment of choice for laceration >4 cm. For laceration between 2–4 cm, the best treatment is debate; some authors recommend surgery while others do not definitely exclude endoscopic treatment. Herein, we reported the endoscopic treatment with fibrin glue of PITL. The procedure is performed using a standard video-bronchoscopy in operating room; the patient is in spontaneous breathing and deep sedation. After identification of tracheal laceration, the fibrin glue is injected through a dedicated double lumen catheter into the lesion. After mixing both components of fibrin glue, polymerization of fibrin occurs resulting in an elastic and opaque clot that closes the lesion. The key success of the procedure is based on accurate patient selection. Patients are eligible if (I) they are clinically stable and in spontaneous respiration; (II) with a small and superficial tracheal laceration (≤4 cm in length and without oesophageal injury); (III) localized at level of the upper or middle trachea; and (IV) without clinical and/or radiological signs of mediastinal collection, of emphysema or pneumomediastinum progression, and of infection.

Laparoscopic repairs for perforated peptic ulcer (PPU) are likely to fail in patients with shock, gastric outlet obstruction, or large perforations. This prospective study was performed to evaluate a revised approach of laparoscopic repair with endoscopic assistance to treat these patients. Between April 2001 and February 2002, 30 consecutive patients with PPU were enrolled in this study. The mean age was 43.1 +/- 12.2 years. Male to female ratio was 27:2. One patient was excluded from laparoscopic repair due to a gastric outlet obstruction. The other 29 patients were managed according to a protocol of preoperative upper endoscopy and laparoscopic intracorporeal suture repair with an omental patch. The average operative time was 58.1 +/- 13.5 minutes (range, 36-96 min). The average diameter of perforation was 4.2 +/- 2.0 mm (range, 1-12 mm). The average time to resume oral fluids was 3.2 +/- 0.8 days (range, 2-8 days). The average hospital stay was 4.7 +/- 1.1 days (range, 3-10 days). There was no leakage or mortality. Most patients did not receive parenteral analgesics postoperatively. We conclude that endoscope-assisted laparoscopic repair for PPU is safe and effective. This revised technique allows surgeons to exclude patients who are likely to fail the laparoscopic repair.

We assessed the effectiveness and safety of holmium:YAG laser lithotripsy for managing upper urinary tract calculi in a prospective cohort of 598 patients. Ureteroscopic holmium:YAG laser lithotripsy was performed in 598 patients between 1993 and 1999. Calculi were located in the distal ureter in 39.6% of cases, mid ureter in 18.6%, proximal ureter in 32.4% and kidney in 9.4%. Patients were treated on an outpatient basis with various flexible and semirigid endoscopes. Of the cases 59% were referred as previous treatment failures. Patients were assessed 6 to 12 weeks postoperatively with repeat plain x-ray and ultrasound or excretory urography for late obstructive complications. The overall stone-free rate was 97%. As stratified by location, the stone-free rate was 98% in the distal ureter, 100% in the mid ureter, 97% in the proximal ureter and 84% in the kidney. Fragmentation was incomplete in 6% of cases and secondary intervention was required in 6%. The overall complication rate was 4%. New onset ureteral stricture developed postoperatively in 0.35% of patients. Holmium:YAG laser lithotripsy is a highly effective and safe treatment modality for managing ureteral and a proportion of intrarenal calculi on an outpatient basis. The effectiveness and versatility of the holmium laser combined with small rigid or flexible endoscopes make it our modality of choice for ureteroscopic lithotripsy.

Gastric polyps are usually found incidentally during upper gastrointestinal endoscopic examinations. These polyps are generally benign, with hyperplasia being the most common. While gastric polyps are often asymptomatic, they can cause gastric outlet obstruction. A 64 years-old female patient presented to our polyclinic with a history of approximately 2 months of weakness, occasional early nausea, vomiting after meals and epigastric pain. A polypoid lesion of approximately 25mm in diameter was detected in the antral area of the stomach, which prolapsed through the pylorus into the duodenal bulbus, and subsequently caused gastric outlet obstruction, as revealed by upper gastrointestinal endoscopy of the patient. The polyp was retrieved from the pyloric canal into the stomach with the aid of a tripod, and snare polypectomy was performed. Currently, widespread use of endoscopy has led to an increase in the frequency of detecting hyperplastic polyps. While most gastric polyps are asymptomatic, they can cause iron deficiency anemia, acute pancreatitis and more commonly, gastric outlet obstruction because of their antral location. Although there are no precise principles in the treatment of asymptomatic polyps, polyps >5mm should be removed due to the possibility of malignant transformation. According to the medical evidence, polypectomy is required for gastric hyperplastic polyps because of the risks of complication and malignancy. These cases can be successfully treated endoscopically.

To observe ulcer characteristics of Crohn's disease under double balloon enteroscopy, and to evaluate the correlation between endoscopic severity and clinical manifestations. Methods: A prospective, observational study from July 2015 to December 2016 in the Third Xiangya Hospital, Central South University, we selected 45 patients with positive double-balloon enteroscopy (DBE) and confirmed Crohn's disease. Two digestive internal physician observed the ulcer characteristics of Crohn's disease under double balloon enteroscopy, and gave a simple endoscopic score for CD (SES-CD). We analyzed the correlation between SES-CD and Crohn's disease activity index (CDAI). Results: DBE indicated 24 patient ulcers (53.33%) locating at the end of the ileum, 5 (11.11%) locating at ileocolon, 16 (35.56%) locating at upper gatrointestinal tract and they did not affect the end of the ileum. Among them, 8 cases (17.78%) affected only jejunum. Thirty-two patients with longitudinal ulcers in Crohn's disease, accounting for 71.11%. There was no correlation between SES-CD score and CDAI score (r=0.237, P=0.136). Conclusion: The ulcerative appearance in Crohn's disease were diverse under double balloon enteroscopy. Crohn's disease could only affect the upper gastrointestinal tract or jejunum. The unwounded ileum and ileocecal valve couldn't be a sign to exclude Crohn's disease. CDAI score couldn't fully assess the prognosis of Crohn's disease.

This study was performed to investigate the clinical role of urgent esophagogastroduodenoscopy (EGD) for acute nonvariceal upper gastrointestinal bleeding (ANVUGIB) performed by experienced endoscopists after hours. A retrospective analysis was performed for consecutively collected data of patients with ANVUGIB between January 2009 and December 2010. A total of 158 patients visited the emergency unit for ANVUGIB after hours. Among them, 60 underwent urgent EGD (within 8 hours) and 98 underwent early EGD (8 to 24 hours) by experienced endoscopists. The frequencies of hemodynamic instability, fresh blood aspirate on the nasogastric tube, and high-risk endoscopic findings were significantly higher in the urgent EGD group. Primary hemostasis was achieved in all except two patients. There were nine cases of recurrent bleeding, and 30-day mortality occurred in three patients. There were no significant differences between the two groups in primary hemostasis, recurrent bleeding, and 30-day mortality. In a multiple linear regression analysis, urgent EGD significantly reduced the hospital stay compared with early EGD. In patients with a high clinical Rockall score (more than 3), urgent EGD tended to decrease the hospital stay, although this was not statistically significant (7.7 days vs. 12.0 days, p > 0.05). Urgent EGD after hours by experienced endoscopists had an excellent endoscopic success rate. However, clinical outcomes were not significantly different between the urgent and early EGD groups.
Outcomes studies of the gastrointestinal safety of cyclooxygenase-2 inhibitors.
Scheiman, James M
2002-01-01
Short-term endoscopic studies of the highly selective cyclooxygenase-2 (COX-2) inhibitors (coxibs) rofecoxib and celecoxib have shown that these agents are well tolerated and have efficacy equivalent to nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) with fewer adverse effects on the upper gastrointestinal (GI) tract. These studies are limited, however, as the detection of endoscopic lesions is not well correlated with symptomatic ulcers and ulcer complications. Outcomes studies of the GI safety are, therefore, essential to understanding how coxibs are likely to perform in a clinical practice setting. Four large outcomes studies (Vioxx Gastrointestinal Outcomes Research, VIGOR; Assessment of Difference Between Vioxx and Naproxen to Ascertain Gastrointestinal Tolerability and Effectiveness trial, ADVANTAGE; Celecoxib Long-term Arthritis Safety Study, CLASS; and the Successive Celecoxib Efficacy and Safety Studies, SUCCESS) examined the GI safety of rofecoxib and celecoxib in over 39,000 patients with osteoarthritis or rheumatoid arthritis. Results of these studies showed that patients taking a supratherapeutic dose of rofecoxib or celecoxib had significantly lower rates of GI-related adverse events than those taking a nonselective NSAID (naproxen, ibuprofen, or diclofenac). Reduced risk of upper GI events was seen in patients with multiple risk factors and in patients using low-dose aspirin and corticosteroids concomitantly with a coxib. Results of large outcomes studies provide support for the COX-2 hypothesis and demonstrate the long-term safety and tolerability of coxibs.

The timely detection of early gastric cancer (EGC) is important in performing endoscopic submucosal dissection (ESD). We attempted to determine the location characteristics of regions where EGC is frequently detected and analyzed the EGC characteristics associated with that location. We retrospectively reviewed the medical records of patients with EGC treated by ESD between November 2008 and August 2016. We retrospectively investigated and analyzed 647 EGC lesions. The patients' mean age was 66.7 ± 10.8 years. The patient population was predominantly male (77.1%, 499/647). A well-to-moderately differentiated carcinoma was observed in 97.2% of patients. The common site of carcinoma occurrence was the lower part of the stomach (the antrum and lower third of body, 89.6%). Among the stomach hemispheres, the lesser curvature side was the most frequent site of EGC (43.9%). The posterior side of EGC was more frequent than anterior side of EGC (20.4 vs. 15.6%, respectively). Submucosal invasive EGC was more frequent in the mid-to-upper parts of stomach than lower part of stomach (odds ratio 1.919; confidence interval 1.014-3.623; p = 0.045). Most EGCs that are resectable with ESD were found in the lower part and in the lesser curvature of the stomach. The submucosal invasive EGC was more frequent in the mid-to-upper part of stomach.

to describe the main topographic and anatomical features of the clival region and its adjacent structures for improvement and optimization of the extended endoscopic endonasal posterior (transclival) approach for resection of tumors of the clival region and ventral posterior cranial fossa. We performed a craniometric study of 125 human skulls and a topographic anatomical study of heads of 25 cadavers, the arterial and venous bed of which was stained with colored silicone (the staining technique was developed by the authors) to visualize bed features and individual variability. Currently, we have clinical material from more than 120 surgical patients with various skull base tumors of the clival region and ventral posterior cranial fossa (chordomas, pituitary adenomas, meningiomas, cholesteatomas, etc.) who were operated on using the endoscopic transclival approach. We present the main anatomical landmarks and parameters of some anatomical structures that are required for performing the endoscopic endonasal posterior approach. The anatomical landmarks, such as the intradural openings of the abducens and glossopharyngeal nerves, may be used to arbitrarily divide the clival region into the superior, middle, and inferior thirds. The anatomical landmarks important for the surgeon, which are detected during a topographic anatomical study of the skull base, facilitate identification of the boundaries between the different clival portions and the C1 segments of the internal carotid arteries. The superior, middle, and inferior transclival approaches provide an access to the ventral surface of the upper, middle, and lower neurovascular complexes in the posterior cranial fossa. The endoscopic transclival approach may be used to access midline tumors of the posterior cranial fossa. The approach is an alternative to transcranial approaches in surgical treatment of clival region lesions. This approach provides results comparable (and sometimes better) to those of the transcranial and transfacial approaches.

Roux-en-Y gastric bypass is a common surgical procedure used to treat patients with morbid obesity. One of the rare, but potentially fatal complications of gastric bypass is upper gastrointestinal bleeding, which can pose diagnostic and therapeutic dilemmas. This report describes a 39-year-old male with morbid obesity who underwent a Roux-en-Y gastric bypass. Three months postoperatively, he sustained repeated and severe upper attacks of upper gastrointestinal bleeding. He received multiple blood transfusions, and had repeated upper and lower endoscopies with no diagnostic yield. Finally, he underwent laparoscopic endoscopy which revealed a bleeding duodenal ulcer. About 5 ml of saline with adrenaline was injected, followed by electrocoagulation to seal the overlying cleft and blood vessel. He was also treated with a course of a proton pump inhibitor and given treatment for H pylori eradication with no further attacks of bleeding. Taking in consideration the difficulties in accessing the bypassed stomach endoscopically, laparoscopic endoscopy is a feasible and valuable diagnostic and therapeutic procedure in patients who had gastric bypass.

We are reporting the first-to our knowledge-case of duodenal Plexiform Fibromyxoma causing obscure upper gastrointestinal bleeding. Plexiform fibromyxoma triggered recurrent upper gastrointestinal bleeding episodes in a 63-year-old man who remained undiagnosed, despite multiple hospitalizations, extensive diagnostic workups and surgical interventions (including gastrectomies), for almost 17 years. During hospitalization for the last bleeding episode, an upper gastrointestinal endoscopy revealed an intestinal hemorrhagic nodule. The lesion was deemed unresectable by endoscopic means. An abdominal computerized tomography disclosed no further lesions and surgery was decided. The lesion at operation was found near the edge of the duodenal stump and treated with pancreas-preserving duodenectomy (1st and 2nd portion). Postoperative recovery was mainly uneventful and a 20-month follow-up finds the patient in good health with no need for blood transfusions.Plexiform fibromyxomas stand for a rare and widely unknown mesenchymal entity. Despite the fact that they closely resemble other gastrointestinal tumors, they distinctly vary in clinical management as well as the histopathology. Clinical awareness and further research are compulsory to elucidate its clinical course and prognosis.

Stricture at the gastrojejunal anastomosis after Roux-en-Y gastric bypass is a significant sequela that often requires intervention. The diagnosis of stricture is usually established by a recognized constellation of symptoms, followed by contrast radiography or endoscopy. The purpose of this report was to evaluate the accuracy of contrast swallow studies in excluding the diagnosis of gastrojejunal stricture. A retrospective analysis of the charts of 119 patients who had undergone laparoscopic Roux-en-Y gastric bypass, representing 41 upper gastrointestinal (GI) swallow studies, was conducted. Of those patients who underwent GI swallow studies, 30 then underwent definitive upper endoscopy to confirm or rule out stricture. The overall sensitivity, specificity, and negative predictive value of the swallow studies were calculated. Of the 30 patients who underwent upper endoscopic examination for symptoms of stricture after laparoscopic gastric bypass, 20 were confirmed to have a stricture. The sensitivity, specificity, and negative predictive value of the upper GI swallow study in this group was 55%, 100%, and 53%, respectively. The demographics of the patients with strictures were similar to those of the study group as a whole. The results of our study have shown that a positive upper GI swallow study is 100% specific for the presence of stricture. However, the sensitivity and negative predictive value of upper GI swallow studies were poor, making this modality unsatisfactory in definitively excluding the diagnosis of gastrojejunal stricture.
Infectious mononucleosis and bilateral peritonsillar abscesses resulting in airway obstruction.
Burstin, P P; Marshall, C L
1998-12-01
Upper airway obstruction is an uncommon but recognized complication of infectious mononucleosis. The management depends upon the degree of airway compromise. In the case described, severe airway obstruction was treated by securing the airway with awake fibre-optic endoscopic intubation and then proceeding to tonsillectomy. Bilateral inferiorly loculated quinsies were encountered unexpectedly and drained. This is the first report of 'bilateral' quinsies, associated with infectious mononucleosis and severe airway obstruction. The association, pathogenesis and significance of this finding are also discussed.

Acute pancreatitis is rare in pregnancy but it is associated with increased incidence of maternal and fetal mortality. It should be considered in the differential diagnosis of upper quadrant abdominal pain with or without nausea and vomiting. The commonest identified causes of acute pancreatitis in pregnancy are gallstones, alcohol and hypertriglyceridemia. The main laboratory finding is increased amylase activity. Appropriate investigations include ultrasound of the right upper quadrant and measurement of serum triglycerides and ionized calcium. Management of gallstone pancreatitis is controversial, although laparoscopic cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) are often used and may be associated with lower complication rates. In hypertriglyceridemia-induced acute pancreatitis ω-3 fatty acids and even therapeutic plasma exchange can be used. We also discuss preventive measures. Copyright © 2011 Elsevier Ireland Ltd.

Post-gastrectomy anastomosis site obstruction is a relatively rare complication after a subtotal gastrectomy. We present a case of a 75-year-old man who underwent a truncal vagotomy, omental patch, gastrojejunostomy, and Braun anastomosis for duodenal ulcer perforation and a gastric outlet obstruction. Following the 10(th) postoperative day, the patient complained of abdominal discomfort and vomiting. We diagnosed post-gastrectomy anastomosis site obstruction by an upper gastrointestinal series and an upper endoscopic examination. We inserted a self-expandable metallic stent (SEMS) at the anastomosis site. The stent was fully expanded after deployment. On the day following the stent insertion, the patient began to eat, and his abdominal discomfort was resolved. This paper describes the successful management of post-gastrectomy anastomosis site obstruction with temporary placement of a SEMS.

Upper gastrointestinal bleeding implies significant clinical and economic repercussions. The correct establishment of the latest therapies for the upper gastrointestinal bleeding is associated with reduced in-hospital mortality. The use of clinical pathways for the upper gastrointestinal bleeding is associated with shorter hospital stay and lower hospital costs. The primary objective is the development of a clinical care pathway for the management of patients with upper gastrointestinal bleeding, to be used in tertiary hospital. It was conducted an extensive literature review on the management of upper gastrointestinal bleeding, contained in the primary and secondary information sources. The result is a clinical care pathway for the upper gastrointestinal bleeding in patients with evidence of recent bleeding, diagnosed by melena or hematemesis in the last 12 hours, who are admitted in the emergency rooms and intensive care units of tertiary hospitals. In this compact and understandable pathway, it is well demonstrated the management since the admission, with definition of the inclusion and exclusion criteria, passing through the initial clinical treatment, posterior guidance for endoscopic therapy, and referral to rescue therapies in cases of persistent or rebleeding. It was also included the care that must be taken before hospital discharge for all patients who recover from an episode of bleeding. The introduction of a clinical care pathway for patients with upper gastrointestinal bleeding may contribute to standardization of medical practices, decrease in waiting time for medications and services, length of hospital stay and costs.

To retrospectively review a series of children with anterior urethral valves (AUV), with emphasis on patterns of urodynamic change and long-term outcome of endoscopic treatment. We reviewed the medical records of eight patients who had undergone thorough radiological and urodynamic exams before and after treatment. The diagnosis of AUV was based on radiological imaging and confirmed by urethrocystoscopy. The valves were ablated through either transurethral fulguration or resection. The upper urinary tracts were studied by renal scan and ultrasonography before and after the procedure. Bladder function was assessed urodynamically 3 months after surgery. Uroflowmetry was performed as soon as the children were toilet trained. Endoscopic ablation of AUV was successful in all cases and no surgical complications occurred. The initial symptoms resolved in all boys. VUR disappeared in two out of three patients, and five children had bladder trabeculation that was resolved after surgery. The final outcome was successful in seven patients (88%). The major urodynamic dysfunction was bladder hypercontractility that resolved following valve ablation. The mean maximum voiding detrusor pressure (P(detmax)) decreased from 213.2+/-17.9 cmH(2)O to 80.7+/-9.9 cmH(2)O, 6 months after treatment (P<0.001). None of the patients had low-compliant bladder, detrusor instability or myogenic failure. The voiding pattern in all toilet-trained patients was staccato and of an interrupted shape prior to surgery, but changed to a normal bell-shaped voiding pattern following valve ablation. AUV should be considered in the differential diagnosis of patients presenting with infravesical obstruction. We recommend endoscopic valve ablation as the treatment of choice.

Background/Aims Duodenitis is not infrequent finding in patient undergoing endoscopy. However, hospitalized patients have a higher incidence of secondary duodenal mucosal lesions that might be related with inflammatory bowel disease (IBD), cytomegalovirus (CMV) infection, tuberculosis, immunologic disorders, or other rare infections. We aimed to identify clinicopathologic features of duodenal mucosal lesions in hospitalized patients. Methods All hospitalized patients having duodenal mucosal lesions were identified by endoscopic registration data and pathologic data query from 2011 to 2014. The diagnostic index was designed to be sensitive; however, a detailed review of medical record and endoscopic findings was undertaken to improve specificity. Secondary duodenal lesion was defined as having specific reason to explain the duodenal lesion. Results Among 6,334 hospitalized patients have undergone upper endoscopy, endoscopic duodenal mucosal lesions was detected in 475 patients. Secondary duodenal lesions was 21 patients (4.4%) and the most frequent secondary cause was IBD (n = 7). The mean age of secondary group was significantly lower than that in primary group (42.3 ± 18.9 years vs. 58.5 ± 16.8 years, p = 0.00), and nonsteroidal anti-inflammatory drugs were less frequently used in secondary group, but there was no differences of gender or presence of Helicobacter pylori. The involvement of distal part of duodenum including postbulbitis or panduodenitis was more frequently detected in secondary group than in primary group. By multivariate regression analysis, younger age of 29 years and the disease extent were significant predictors for the secondary mucosal lesions. Conclusions Secondary duodenal mucosal lesions with different pathophysiology, such as IBD or CMV infection, are rare. Disease extent and age seems the most distinctive feature of secondary duodenal mucosal lesions. PMID:28823115

Our main objective was to study gastritis associated to duodeno-gastric reflux. It is about a longitudinal study case/witness, paired according to the sex and the age. It was unrolled from February 2005 to January 2006 in the digestive diseases department of the hospital Gabriél Touré, and endoscopic centers of Promenade des Angevins, and clinique Farako. The patients profited from an upper digestive endoscopy to appreciate endoscopic aspect of gastritis associated to bile in the stomach mucus lake. The gastric biopsies were systematic. This study included 50 patients having gastritis associated to bile in gastric mucus lake compared to 50 patients having gastritis associated to clearly gastric mucus lake. The sex-ratio was 1.26 in favour of men. The average age of the patients was of 41.30 +/- 15.43 years. On the symptomatic hand, fetid breath was significantly met in duodeno-gastric reflux (p = 0.013). Potash consumption in the "tô" (millet cake) was significantly reported in gastritis associated to bile in gastric mucus lake (p = 0.042). The endoscopic aspects were comparable. Histological aspects of nonatrophic chronic gastritis were significantly mint in witnesses as well into the antrum as into the fundus (p = 0.0001 and p = 0.00023). The reactional gastritis aspect was the prerogative of duodenogastric reflux (p ranging between 10(-6) and 3.10 (-6). Helicobacter pylori infection was found comparable in the two groups (p = 0.297). Dysplasia although rare was found only in gastritis associated to duodeno-gastric reflux. Gastritis associated to bile in gastric mucus does not se,nm to have specific clinical, endoscopic and histological presentation. However the presence of dysplasia must have an attentive monitoring.

Achieving a clear distal or circumferential resection margins with laparoscopic total mesorectal excision (TME) may be laborious, especially in obese males and when operating on advanced distal rectal tumors with a poor response to neoadjuvant treatment. Transanal (TaTME) is a new natural orifice translumenal endoscopic surgery modality in which the rectum is mobilized transanally using endoscopic techniques with or without laparoscopic assistance. We conducted a comprehensive systematic review of publications on this new technique in PubMed and Embase databases from January, 2008, to July, 2014. Experimental and clinical studies written in English were included. Experimental research with TaTME was done on pigs with and without survival models and on human cadavers. In these studies, laparoscopic or transgastric assistance was frequently used resulting in an easier upper rectal dissection and in a longer rectal specimen. To date, 150 patients in 16 clinical studies have undergone TaTME. In all but 15 cases, transabdominal assistance was used. A rigid transanal endoscopic operations/transanal endoscopic microsurgery (TEO/TEM) platform was used in 37 patients. Rectal adenocarcinoma was the indication in all except for nine cases of benign diseases. Operative times ranged from 90 to 460 min. TME quality was deemed intact, satisfactory, or complete. Involvement in circumferential resection margins was detected in 16 (11.8 %) patients. The mean lymph node harvest was equal or greater than 12 in all studies. Regarding morbidity, pneumoretroperitoneum, damage to the urethra, and air embolism were reported intraoperatively. Mean hospital stay varied from 4 to 14 days. Postoperative complications occurred in 34 (22.7 %) patients. TaTME with TEM is feasible in selected cases. Oncologic safety parameters seem to be adequate although the evidence relies on small retrospective series conducted by highly trained surgeons. Further studies are expected.

To describe the use of fiberoptic endoscopic evaluation of swallowing (FEES) as an adjunct in the management of children presenting with psychogenic dysphagia, defined as food avoidance and excessive fear of eating without identifiable anatomic or functional swallowing abnormalities. Case series of patients presenting to the otolaryngology clinic of a tertiary pediatric teaching hospital between 2007 and 2008 that were evaluated and managed with the utilization of FEES. The outcomes measured were age, gender, duration of symptoms, findings of FEES, additional work-up and resolution of symptoms at follow-up. Five patients (4 males, 1 female) with ages ranging from 5 to 13 years old (mean=8.6). The median duration of symptoms before presentation was 3 weeks. Four families described refusal of solids starting after choking episode and variable estimated weight loss (mean 2.8kg). One child presented with vague complaints of intermittent odynophagia and food refusal. Fiberoptic endoscopic evaluation of swallowing was performed on all patients. No abnormalities of the oropharyngeal swallow were appreciated. Additional management included different combinations of modified barium swallow study, esophagastroduodenoscopy (EGD), upper GI series, antibiotics, and psychotherapy. Mean follow-up with clinic visit was 4.2 months. Three of the five children reported complete resolution of symptoms after FEES at follow-up visit. Fiberoptic endoscopic evaluation of swallowing can be a useful management tool in children with psychogenic dysphagia as it provides direct visualization of the oropharyngeal swallowing mechanism. This can be used to provide visual reassure and biofeedback to patients and parents. Additional workup should be decided on an individual basis. Copyright © 2014 Elsevier Ireland Ltd.

The need for endoscopic investigation in patients with iron deficiency without anemia (ID) is not established. Data from patients with ID (serum ferritin ≤20 ng/mL, normal hemoglobin) studied with upper and lower endoscopies were retrospectively analyzed. Patients evaluated for iron deficiency anemia (IDA) served as controls, matched by sex and age in the proportion of 2:1. The groups were compared for the presence, type, location and age distribution of endoscopic findings. Altogether 109 patients (55% women; mean age 59.6 ± 13.5 years; aged <50 years [27.5%]; 50-69 years [43.1%]; ≥70 years [29.4%]) were included in the ID group and 218 matched controls in the IDA group. Lesions were found in a similar proportion of patients (53.2% in the ID group vs 49.1% in the IDA group, P = 0.48) irrespective of age (P = 0.92). The colonoscopy diagnostic yield was low in both the ID and IDA subgroups of aged <50 years (6.3% vs 4.2%, P = 0.76). Multivariate analysis revealed a significant relationship between age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02-1.06) and male sex (OR 2.28, 95% CI 1.18-4.39) with a positive colonoscopy. Malignancy was significantly less frequent in the ID group (1.8% vs 14.2%, P < 0.05). The prevalence of gastrointestinal lesions in patients with and without anemia was similar but malignancy was eight times less frequent in the ID group. Systematic endoscopic evaluation in patients with ID is therefore questionable. © 2017 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

Previous studies have shown similar effects of rabeprazole and omeprazole, when used at the same dose in the treatment of reflux oesophagitis. However, such studies have been conducted as superiority studies but interpreted as equivalence ones. To properly assess the comparative efficacy of rabeprazole and omeprazole in inducing complete endoscopic healing and symptom relief in patients with reflux oesophagitis. Patients (n=560) with Savary-Miller grade I-III reflux oesophagitis were randomised in a double-blind, double-dummy fashion to rabeprazole or omeprazole 20 mg once daily for 4-8 weeks. Then, patients endoscopically healed and symptomatically relieved were openly maintained with rabeprazole 10 mg or 2x10 mg once daily (in the event of clinical and/or endoscopic relapse) for a maximum of 48 weeks. After 4-8 weeks of treatment, healing (primary end-point) was observed in 228/233 (97.9%) patients in the rabeprazole group and in 231/237 (97.5%) in the omeprazole one (equivalence effect demonstrated by p<0.0001 at Blackwelder test and an upper confidence limit at 97.5% of 0.023). However, rabeprazole was faster in inducing heartburn relief than omeprazole (2.8+/-0.2 versus 4.7+/-0.5 days of therapy to reach the first day with satisfactory heartburn relief, p=0.0045 at log-rank test). In the maintenance phase, 15.2% of patients had an endoscopic and/or clinical relapse. Rabeprazole is equivalent to omeprazole in healing reflux oesophagitis, but shows a faster activity on reflux symptoms in the early treatment phase.

Dumping syndrome is a long-term postoperative complication of Roux-en-Y gastric bypass procedures. Morphologically, dumping syndrome usually correlates with a dilatation of the gastroenterostomy with accelerated pouch emptying. Conservative therapy includes diet changes, complementary pharmacotherapy and, if symptoms persist, surgical revision. Surgical options include endoscopic, endoluminal surgery to constrict the gastrojejunostomy using a novel endoscopic suturing device (OverStitch(TM), Apollo). In our study, we aimed to assess the viability, safety and efficacy of this procedure in patients with late dumping; 14 patients who had developed late dumping syndrome underwent surgery using an endoscopic suturing technique (OverStitch(TM), Apollo). Late dumping was confirmed by Sigstad score and an oral glucose tolerance test (OGTT). Prior to surgery, objective analysis of pouch emptying speed was assessed by gastric scintigraphy. Surgery was performed under general anaesthesia. None of the 14 patients suffered intra- or postoperative complications. No postsurgical increase in inflammation parameters was observed. The postinterventional pain scale (visual analogue scale) showed a mean score of 0.5 (range 0-10). In 13 of the 14 patients, no dumping was observed 1-month postsurgery. The postoperative Sigstad score (3.07 ± 2.06; range 1-9) showed an impressive reduction compared with the preoperative score (12.71 ± 4.18; range 7-24) (p < 0.001). Postoperative upper gastrointestinal gastrografin swallow revealed regular emptying in all the patients. The endoluminal endoscopic suturing technique-applied here for surgical revision of gastroenterostomy following Roux-en-Y gastric bypass-represents a promising, novel therapeutic option in late dumping syndrome involving minimal trauma and offering rapid reconvalescence.

To evaluate the prognostic factors, including risk scores (Glasgow-Blatchford score and AIMS65) in patients with acute upper or lower gastrointestinal bleeding. The medical records of patients who had undergone emergency gastrointestinal endoscopy for suspected gastrointestinal bleeding during the past 5 years were retrospectively analyzed. A total of 232 endoscopies (130 esophagogastroduodenoscopies, 102 colonoscopies) for 192 patients met the inclusion criteria. Median age was 66 years, and 64% of patients were males. Endoscopy identified causes for bleeding in 173 patients (post-endoscopic interventions for neoplastic lesions in 36 cases, colonic diverticula in 34, gastroduodenal ulcers in 29, gastric erosions in 15, vascular ectasia in 14, post-biopsy bleeding in 13, malignant tumors in 10, inflammatory conditions in nine, esophagogastric varices in five, Mallory-Weiss tears in four, nasalbleeding in three, and injury by swallowed blister pack in one), whereas the source of bleeding remained obscure in 19 patients. Blood transfusion was given in 97 patients (51%), and 97 (51%) underwent endoscopic hemostasis. During the follow-up period, 49 patients (26%) experienced rebleeding, seven of whom were treated by interventional radiology. Thirty-nine patients (20%) died as a result of various diseases. The probabilities of overall survival (OS) after 3 and 5 years were 71% and 67%, respectively. Cox multivariate analysis revealed blood transfusion, co-existing malignancy, absence of endoscopic hemostasis, and high AIMS65 score to be independent prognostic factors for poor OS. The AIMS65 score is useful for predicting the prognosis of patients with acute gastrointestinal bleeding. © 2013 The Authors. Digestive Endoscopy © 2013 Japan Gastroenterological Endoscopy Society.

Upper gastrointestinal bleeding (UGIB) is a common emergency gastrointestinal problem which has substantial mortality and health care resources use. The nationwide basic information on UGIB is not available in Thailand. To identify the hospitalized incidence, outcomes and hospitalization cost of patients who presented with UGIB in Thailand. Information on illness of in-patients from hospitals nationwide was retrieved from three major health schemes database in fiscal year 2010. The hospitalized incidence rate of UGIB was 166.3 admissions per 100,000 populations and the hospitalized incidence rate of non-variceal upper gastrointestinal bleeding (NVUGIB) and variceal bleeding were 152.9 and 13.5 admissions per 100,000 populations respectively. Endoscopic procedure was undertaken in 27.6% of NVUGIB admissions and 80.7% of variceal bleeding admissions. The in-hospital mortality rate, hospitalization cost and length of stay were higher in variceal bleeding patients compared with NVUGIB patients. UGIB is an important emergency gastrointestinal problem which has significant mortality and substantial health care resources consumption.
Management by the intensivist of gastrointestinal bleeding in adults and children
2012-01-01
Intensivists are regularly confronted with the question of gastrointestinal bleeding. To date, the latest international recommendations regarding prevention and treatment for gastrointestinal bleeding lack a specific approach to the critically ill patients. We present recommendations for management by the intensivist of gastrointestinal bleeding in adults and children, developed with the GRADE system by an experts group of the French-Language Society of Intensive Care (Société de Réanimation de Langue Française (SRLF), with the participation of the French Language Group of Paediatric Intensive Care and Emergencies (GFRUP), the French Society of Emergency Medicine (SFMU), the French Society of Gastroenterology (SNFGE), and the French Society of Digestive Endoscopy (SFED). The recommendations cover five fields of application: management of gastrointestinal bleeding before endoscopic diagnosis, treatment of upper gastrointestinal bleeding unrelated to portal hypertension, treatment of upper gastrointestinal bleeding related to portal hypertension, management of presumed lower gastrointestinal bleeding, and prevention of upper gastrointestinal bleeding in intensive care.

Imaging of the human upper airway is widely used in medicine, in both clinical practice and research. Common imaging modalities include video endoscopy, X-ray CT, and MRI. However, no current modality is both quantitative and safe to use for extended periods of time. Such a capability would be particularly valuable for sleep research, which is inherently reliant on long observation sessions. We have developed an instrument capable of quantitative imaging of the human upper airway, based on endoscopic optical coherence tomography. There are no dose limits for optical techniques, and the minimally invasive imaging probe is safe for use in overnight studies. We report on the design of the instrument and its use in preliminary clinical studies, and we present results from a range of initial experiments. The experiments show that the instrument is capable of imaging during sleep, and that it can record dynamic changes in airway size and shape. This information is useful for research into sleep disorders, and potentially for clinical diagnosis and therapies.

Vasculopathy is rarely reported in neurofibromatosis type 1, but when it occurs it primarily involves the aorta and its main branches. Among vasculopathies, aneurysmal dilatation is the most common form. Although several case reports concerning aneurysms or pseudoaneurysms of visceral arteries in neurofibromatosis type 1 patients have been reported, there are no reports describing gastroduodenal artery aneurysms associated with neurofibromatosis type 1. We experienced a case of life-threatening duodenal ulcer bleeding from a ruptured gastroduodenal artery aneurysm associated with neurofibromatosis type 1. We treated our patient by transarterial embolization after initial endoscopic hemostasis. To our knowledge, this is the first reported case of its type. High levels of suspicion and prompt diagnosis are required to select appropriate treatment options for patients with neurofibromatosis type 1 experiencing upper gastrointestinal bleeding. Embolization of the involved arteries should be considered an essential treatment over endoscopic hemostasis alone to achieve complete hemostasis and to prevent rebleeding.

Vagus nerve stimulation (VNS) is a useful tool for drug-resistant epilepsy, but it induces known laryngeal side effects, with a significant role on patients' quality of life. VNS patients may show persistent left vocal fold (LVF) palsy at rest and/or recurrent LVF adduction during stimulation. This study aims at electromyographically evaluating laryngeal muscles abnormalities in VNS patients. We compared endoscopic laryngeal evaluation data in six VNS patients with laryngeal muscle electromyography (LMEMG) carried out on the thyroarytenoid, cricothyroid, posterior cricoarytenoid, and cricopharyngeal muscles. Endoscopy showed LVF palsy at rest in 3/6 patients in whom LMEMG documented a tonic spastic activity with reduced phasic modulation. In four out of six patients with recurrent LVF adduction during VNS activation, LMEMG showed a compound muscle action potential persisting for the whole stimulation. This is the first LMEMG report of VNS-induced motor unit activation via recurrent laryngeal nerve and upper laryngeal nerve stimulation. LMEMG data were could, therefore, be considered consistent with the endoscopic laryngeal examination in all patient.

Cyanoacrylate injection is a recognised endoscopic treatment option for variceal haemorrhage. We describe a 34-year old man with hepatitis B cirrhosis who presented to the hospital with upper gastrointestinal haemorrhage from gastric and oesophageal varices. Haemostasis was achieved via cyanoacrylate injection sclerotherapy and banding. Ten days later, the patient developed acute hypoxia and fever. His chest radiograph showed wide-spread pulmonary shadowing. A non-contrast CT scan confirmed multiple emboli of injected glue material from the varix with parenchymal changes either suggesting acute lung injury or pulmonary oedema. He gradually recovered with supportive treatment and was discharged home. On follow-up, he remained asymptomatic from a chest perspective. This case report discusses the rare complication of pulmonary embolisation of cyanoacrylate glue from variceal injection sites and the diagnostic dilemmas involved. Emphasis is placed on the importance of maintaining high index of clinical suspicion when assessing patients with possible procedure related complications. PMID:25320260

Previous studies reported that endoscopic resection is effective for the treatment of superficial pharyngeal cancers, as for digestive tract cancers. However, the optimal treatment for superficial cancer of the uvula has not been established because of the rarity of this condition. We present two male patients in their 70s with superficial cancer of the uvula, detected with upper gastrointestinal endoscopy. Both patients underwent surgical resection of the uvula under general anesthesia. The extent of the lesions was determined by means of gastrointestinal endoscopy by using magnifying observation with narrow-band imaging, enabling the performance of minimally invasive surgery. Endoscopic submucosal dissection was performed to achieve en bloc resection of the intramucosal carcinoma that had infiltrated the area adjacent to the uvula. Gastrointestinal endoscopists should carefully examine the laryngopharynx to avoid missing superficial cancers. Our minimally invasive treatment for superficial cancer of the uvula had favorable postoperative outcomes, and prevented postoperative loss of breathing, swallowing, and articulation functions.

Perforation is a major complication of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). However, there have been no reports on delayed perforation after ESD for EGC. We aimed to elucidate the incidence and outcomes of delayed perforation after ESD. Clinical courses in 1159 consecutive patients with 1329 EGCs who underwent ESD were investigated. Delayed perforation occurred in six patients (0.45 %). All these patients had complete en bloc resection without intraoperative perforation during ESD. Five of six perforations were located in the upper third of the stomach, while one lesion was found in the middle third. Symptoms of peritoneal irritation with rebound tenderness presented within 24 h after ESD in all cases. One patient did not require surgery because the symptoms were localized, and recovered with conservative antibiotic therapy by nasogastric tube placement. The remaining five patients required emergency surgery. There was no mortality in this case series. © Georg Thieme Verlag KG Stuttgart · New York.
Identifying Minimal Changes in Nonerosive Reflux Disease: Is the Pay Worth the Labor?

Gastroesophageal reflux disease has a variable presentation on upper endoscopy. Gastroesophageal reflux disease can be divided into 3 endoscopic categories: Barrett's esophagus, erosive esophagitis, and normal mucosa/nonerosive reflux disease (NERD). Each of these phenotypes behave in a distinct manner, in regards to symptom response to treatment, and risk of development of complications such as esophageal adenocarcinoma. Recently, it has been proposed to further differentiate NERD into 2 categories: those with and those without "minimal changes." These minimal changes include endoscopic abnormalities, such as villous mucosal surface, mucosal islands, microerosions, and increased vascularity at the squamocolumnar junction. Although some studies have shown that patients with minimal changes may have higher rates of esophageal acid exposure compared with those without minimal changes, it is currently unclear if these patients behave differently than those currently categorized as having NERD. The clinical utility of identifying these lesions should be weighed against the cost of the requisite equipment and the additional time required for diagnosis, compared with conventional white light endoscopy.

The European Association of Endoscopic Surgeons (EAES) conducted this study aiming to identify the top research questions which are relevant to surgeons in Minimal Access Surgery (MAS). This is in order to promote and link research questions to the current clinical practice in MAS in Europe. Using a systematic methodology, (modified Delphi), the EAES members and leadership teams were surveyed to obtain consensus on the top research priorities in MAS. The responses were categorized and redistributed to the membership to rate the level of importance of each research question. The data were reported as the weighted average score with a scale from 1 (lowest agreement) to 5 (highest agreement). In total, 324 of 2580 (12.5%) of the EAES members and the leaders responded to the survey and contributed to the final consensus. The ranked responses over the 80th percentile identified 39 research priorities with rating ranged from 4.22 to 3.67. The top five highest ranking research priorities in the EAES were centered on improving training in MAS, laparoscopic surgery for benign upper gastrointestinal conditions, integration of novel technology in OR, translational and basic science research in bariatric surgery and investigating the role of MAS in rectal cancer. An EAES research agenda was developed using a systematic methodology and can be used to focus MAS research. This study was commissioned by the European Association for Endoscopic Surgery (EAES).

Oesophageal lichen planus is an idiopathic inflammatory disorder characterized by significant oesophageal stricturing. Oesophageal lichen planus is a rare, difficult to diagnose, and likely an under recognized disease. As a result, there is no standardized approach to therapy and treatment strategies vary. To examine the utility of topical steroid therapy (fluticasone or budesonide) in the management of oesophageal lichen planus. A retrospective chart review was conducted of patients diagnosed with oesophageal lichen planus who underwent baseline and follow up endoscopy pre and post topical steroid therapy between 1995 and 2016 at Mayo Clinic, Rochester MN. Average time between upper GI endoscopy was 3.2 months (0.7-11.7). Swallowed steroid preparations included fluticasone 880 μg twice daily or budesonide 3 mg twice daily. Patients were reviewed for symptomatic response to therapy using the Dakkak-Bennett dysphagia score (0-4, no dysphagia to total aphagia). Pre- and post-endoscopic findings were assessed. Additional baseline demographic, endoscopic, and histologic data were also obtained. We identified 40 patients who met the inclusion criteria. A significant reduction in median dysphagia score from 1 (0-4) to 0 (0-3) after steroid therapy (P < 0.001) was noted. 62% of patients reported resolution of their dysphagia after receiving topical corticosteroids. 72.5% had an endoscopic response to steroid therapy. Topical swallowed budesonide or fluticasone appear to effective treatment for oesophageal lichen planus. © 2016 John Wiley & Sons Ltd.
How good is the neosquamous epithelium?
Orlando, Roy C
2014-01-01
Endoscopic radiofrequency ablation of dysplastic Barrett's esophagus (BE) combined with proton pump inhibitor therapy is commonly utilized for preventing progression of dysplastic BE to esophageal adenocarcinoma. Fundamental to the success of this and all ablative approaches is the healing of the ablated areas of BE with a stratified squamous epithelium referred to as 'neosquamous epithelium' (NSE). Although NSE appears 'normal' endoscopically, the reemergence of BE over time in the previously ablated segments raises the question of the health and integrity of NSE. The health of NSE was recently investigated in endoscopic biopsies in vitro in a group of patients after ablation while on proton pump inhibitors. Biopsies of NSE were compared to upper squamous epithelium (USE) from the same patients morphologically (light microscopy) and with respect to barrier function by measuring electrical resistance and fluorescein flux in mini-Ussing chambers. Compared to USE, NSE exhibited dilated intercellular spaces and inflammation and defective barrier function by low electrical resistance and high fluorescein flux. Moreover, NSE exhibited downregulation of claudin-4, a highly expressed protein in squamous tight junctions. NSE has defective barrier function in part due to downregulation of claudin-4. Since downregulation of claudin-4 increases paracellular permeability to cations, e.g. hydrogen ions, NSE is more vulnerable to attack and damage by acidic and weakly acidic refluxates--a phenomenon that may contribute in part to the reemergence of BE. 2014 S.

Endoscopic-assisted transaxillary dual-plane (EATD) technique is a popular procedure for breast augmentation, especially for Chinese women. However, frustration is often expressed by plastic surgeons when first attempting EATD surgery. Simulation-based teaching is beneficial for EATD training, but it is expensive. This study presents a low-cost simulator to help plastic surgeons exercise psychomotor skills during EATD surgery. The low-cost simulator was invented by Dr Jie Luan (the senior author) and made of some easily available materials including a mannequin, a T-shirt printed the bottom anatomical structure of the chest, the order of dissection, and the potential bleeding spot, and an elastic compression garment printed the upper anatomical structure and the cut-off position to sever the pectoralis major muscle. The first-year residents of plastic surgery assessed their improvement by completing a 5-item evaluation questionnaire at the beginning and at the end of the simulation. Fifty participants enrolled in this study. There was a significant difference (P < 0.05) before and after the training regarding candidate confidence, anatomical awareness, and endoscope control including the dexterity and hand-to-eye coordination. The low-cost and simple maintenance simulator may help plastic surgeons, especially those in developing countries, to improve gradually their EATD breast augmentation skills with no risks in a way. Further randomized controlled trials are needed to test its validity and reliability.

Objective The aim of this study was to determine the prevalence and risk factors of reflux esophagitis and Helicobacter pylori (H.pylori) infection and their interrelationship in healthy young Japanese volunteers. Methods Between 2010 and 2016, 550 fifth-year medical students at Saga Medical School, aged 22 to 30 years, underwent upper gastrointestinal endoscopy and completed a questionnaire (frequency scale for symptoms of gastroesophageal reflux disease). H. pylori infection was determined by detecting urinary immunoglobulin G antibodies. Results H. pylori antibodies were detected in 45 of the 550 subjects (8.2%). Endoscopic reflux esophagitis was detected in 38 out of 550 (6.9%): grade A in 37 subjects (97.3%) and grade B in 1. Most subjects with reflux esophagitis were H. pylori-negative (35/37). Nodular gastritis was observed in 33.3% (15/45) of H. pylori-positive subjects. The risk factors for H. pylori infection were drinking well water in childhood, nodular gastritis, and duodenal ulcer scars. The risk factors for endoscopic reflux esophagitis were male gender and obesity (body mass index ≥25). Conclusion This study describes the risk factors for H. pylori infection and reflux esophagitis in healthy young Japanese subjects. The prevalence of reflux esophagitis was relatively high, and the infection rate of H. pylori was low compared with the aged Japanese population.

Endoscopic balloon dilatation (EBD) is currently accepted as an effective, safe, and first-line treatment of postoperative benign gastrointestinal anastomosis stenosis (BGAS); however, a limited number of publications on the subject exist in the literature. The aim of the study was to retrospectively evaluate the efficiency of endoscopic dilatation in patients with postoperative intestinal anastomotic stenoses at a single surgical center. Patients with postoperative BGAS treated by EBD at our institution from February 2008 to 2012 were included. The dilatations were all performed using through-the-scope balloons. The balloon was introduced into the stricture using a guidewire under radiologic guidance. Each dilatation session consisted of 2 to 3 two-minute multistep inflations of the balloon until adequate dilatation was achieved. Of the 48 patients included in the study, 44 patients (91.7%) fully recovered and 4 (8.3%) did not respond to treatment. The mean follow-up period was 24 months (range, 3 to 57 mo). Four patients who did not respond to the procedure were treated surgically. Two patients (4.1%) with intestinal perforation during EBD were treated conservatively with a stent. EBD has a low rate of complications and a high success rate, is well tolerated, and avoids further surgical procedures for BGAS. Therefore, EBD should be the first choice of treatment for postoperative anastomotic stenoses.

The aim of this study was to determine the efficacy of pectin solution, which increases the viscosity of liquid nutrient, for prevention of gastro-esophageal reflux in comparison with half-solid nutrient. The subjects were 10 elderly patients undergoing percutaneous endoscopic gastrostomy feeding. Twenty-four-hour esophageal multichannel intraluminal impedance and pH testing was performed during intake of half-solid nutrient and a combination of pectin solution and liquid nutrient. During 4 h after delivery, there was no significant difference in the total number of gastro-esophageal reflux events between the feeding of the half-solid nutrient and the combination of pectin solution and liquid nutrient (5.7 ± 1.2 vs 5.3 ± 1.0/4 h). Acidic reflux after delivery of the half-solid nutrient was significantly more frequent than that after delivery of the combination of pectin solution and liquid nutrient (80.7% vs 60.4%, p = 0.018). The incidence of gastro-esophageal reflux reaching the upper portion of the esophagus tended to be higher during delivery of the half-solid nutrient than during delivery of the combination of pectin solution and liquid nutrient (47.4% vs 34.0%, p = 0.153). In conclusion, the usage of pectin solution combined with liquid nutrient is effective for preventing acidic gastro-esophageal reflux and gastro-esophageal reflux reaching the upper portion of the esophagus.

To explore the utility of endoscopic ultrasound (EUS) in the evaluation of chronic upper abdominal pain (UAP) of undetermined etiology. Chronic UAP is a common problem with a challenging diagnosis and management. The role of EUS in the diagnosis of UAP may minimize additional testing; however, few studies describe the percentage of new diagnoses yielded in these patients. We conducted a retrospective analysis by reviewing electronic medical records at Scott and White Memorial Hospital, Texas A&M Health Sciences Center for patients with abdominal pain for ≥ 12 months not explained by previous workup referred for EUS for chronic UAP from January 1, 1998 through October 1, 2007. Patients with previous EUS in past 12 months were excluded from the study. Patient demographic data and imaging performed 6 months before and 24 months after EUS were reviewed and results documented. EUS was successful at diagnosing a new clinical etiology of chronic UAP in 33 patients (8.89%) with previous workup that was unrevealing for a definitive diagnosis. The most frequent diagnoses included pancreaticobiliary tree abnormalities, chronic pancreatitis, and fatty liver disease. Our results support the fact that the majority of patients UAP with prior imaging will have no identifiable organic etiology found on EUS to explain their pain; however, we suggest that EUS be considered in patients with suspected pancreatic or biliary pathology.

The reasons for aspiration in healthy adults remain unknown. Given that the pharyngeal phase of swallowing is a key component of the safe swallow, it was hypothesized that healthy older adults who aspirate are likely to generate less pharyngeal peak pressures when swallowing. Accordingly, pharyngeal and upper esophageal sphincter pressures were examined as a function of aspiration status (i.e., nonaspirator vs. aspirator), sensor location (upper vs. lower pharynx), liquid type (i.e., water vs. milk), and volume (i.e., 5 vs. 10 ml) in healthy older adults. Manometric measurements were acquired with a 2.1-mm catheter during flexible endoscopic evaluation. Participants (N = 19, mean age = 79.2 years) contributed 28 swallows; during 8 swallows, simultaneous manometric measurements of upper and lower pharyngeal and upper esophageal pressures were obtained. Pharyngeal manometric peak pressure was significantly less for aspirators (mean = 82, SD = 31 mmHg) than for nonaspirators (mean = 112, SD = 20 mmHg), and upper pharyngeal pressures (mean = 85, SD = 32 mmHg) generated less pressure than lower pharyngeal pressures (mean = 116, SD = 38 mmHg). Manometric measurements vary with respect to aspiration status and sensor location. Lower pharyngeal pressures in healthy older adults may predispose them to aspiration. PMID:20623303

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the removal of foreign bodies in the upper gastrointestinal tract in adults. Recommendations Nonendoscopic measures 1 ESGE recommends diagnostic evaluation based on the patient's history and symptoms. ESGE recommends a physical examination focused on the patient's general condition and to assess signs of any complications (strong recommendation, low quality evidence). 2 ESGE does not recommend radiological evaluation for patients with nonbony food bolus impaction without complications. We recommend plain radiography to assess the presence, location, size, configuration, and number of ingested foreign bodies if ingestion of radiopaque objects is suspected or type of object is unknown (strong recommendation, low quality evidence). 3 ESGE recommends computed tomography (CT) scan in all patients with suspected perforation or other complication that may require surgery (strong recommendation, low quality evidence). 4 ESGE does not recommend barium swallow, because of the risk of aspiration and worsening of the endoscopic visualization (strong recommendation, low quality evidence). 5 ESGE recommends clinical observation without the need for endoscopic removal for management of asymptomatic patients with ingestion of blunt and small objects (except batteries and magnets). If feasible, outpatient management is appropriate (strong recommendation, low quality evidence). 6 ESGE recommends close observation in asymptomatic individuals who have concealed packets of drugs by swallowing ("body packing"). We recommend against endoscopic retrieval. We recommend surgical referral in cases of suspected packet rupture, failure of packets to progress, or intestinal obstruction (strong recommendation, low quality evidence). Endoscopic measures 7 ESGE recommends emergent (preferably within 2 hours, but at the latest within 6 hours) therapeutic esophagogastroduodenoscopy for foreign bodies inducing complete esophageal obstruction, and for sharp-pointed objects or batteries in the esophagus. We recommend urgent (within 24 hours) therapeutic esophagogastroduodenoscopy for other esophageal foreign bodies without complete obstruction (strong recommendation, low quality evidence). 8 ESGE suggests treatment of food bolus impaction in the esophagus by gently pushing the bolus into the stomach. If this procedure is not successful, retrieval should be considered (weak recommendation, low quality evidence). The effectiveness of medical treatment of esophageal food bolus impaction is debated. It is therefore recommended, that medical treatment should not delay endoscopy (strong recommendation, low quality evidence). 9 In cases of food bolus impaction, ESGE recommends a diagnostic work-up for potential underlying disease, including histological evaluation, in addition to therapeutic endoscopy (strong recommendation, low quality evidence). 10 ESGE recommends urgent (within 24 hours) therapeutic esophagogastroduodenoscopy for foreign bodies in the stomach such as sharp-pointed objects, magnets, batteries and large/long objects. We suggest nonurgent (within 72 hours) therapeutic esophagogastroduodenoscopy for medium-sized blunt foreign bodies in the stomach (strong recommendation, low quality evidence). 11 ESGE recommends the use of a protective device in order to avoid esophagogastric/pharyngeal damage and aspiration during endoscopic extraction of sharp-pointed foreign bodies. Endotracheal intubation should be considered in the case of high risk of aspiration (strong recommendation, low quality evidence). 12 ESGE suggests the use of suitable extraction devices according to the type and location of the ingested foreign body (weak recommendation, low quality evidence). 13 After successful and uncomplicated endoscopic removal of ingested foreign bodies, ESGE suggests that the patient may be discharged. If foreign bodies are not or cannot be removed, a case-by-case approach depending on the size and type of the foreign body is suggested (weak recommendation, low quality evidence). © Georg Thieme Verlag KG Stuttgart · New York.

Background Upper gastrointestinal (GI) bleeding is recognized as a common and potentially life-threatening abdominal emergency that needs a prompt assessment and aggressive emergency treatment. A retrospective study was undertaken at Bugando Medical Centre in northwestern Tanzania between March 2010 and September 2011 to describe our own experiences with fibreoptic upper GI endoscopy in the management of patients with upper gastrointestinal bleeding in our setting and compare our results with those from other centers in the world. Findings A total of 240 patients representing 18.7% of all patients (i.e. 1292) who had fibreoptic upper GI endoscopy during the study period were studied. Males outnumbered female by a ratio of 2.1:1. Their median age was 37 years and most of patients (60.0%) were aged 40 years and below. The vast majority of the patients (80.4%) presented with haematemesis alone followed by malaena alone in 9.2% of cases. The use of non-steroidal anti-inflammatory drugs, alcohol and smoking prior to the onset of bleeding was recorded in 7.9%, 51.7% and 38.3% of cases respectively. Previous history of peptic ulcer disease was reported in 22(9.2%) patients. Nine (3.8%) patients were HIV positive. The source of bleeding was accurately identified in 97.7% of patients. Diagnostic accuracy was greater within the first 24 h of the bleeding onset, and in the presence of haematemesis. Oesophageal varices were the most frequent cause of upper GI bleeding (51.3%) followed by peptic ulcers in 25.0% of cases. The majority of patients (60.8%) were treated conservatively. Endoscopic and surgical treatments were performed in 30.8% and 5.8% of cases respectively. 140 (58.3%) patients received blood transfusion. The median length of hospitalization was 8 days and it was significantly longer in patients who underwent surgical treatment and those with higher Rockall scores (P < 0.001). Rebleeding was reported in 3.3% of the patients. The overall mortality rate of 11.7% was significantly higher in patients with variceal bleeding, shock, hepatic decompensation, HIV infection, comorbidities, malignancy, age > 60 years and in patients with higher Rockall scores and those who underwent surgery (P < 0.001). Conclusion Oesophageal varices are the commonest cause of upper gastrointestinal bleeding in our environment and it is associated with high morbidity and mortality. The diagnostic accuracy of fibreoptic endoscopy was related to the time interval between the onset of bleeding and endoscopy. Therefore, it is recommended that early endoscopy should be performed within 24 h of the onset of bleeding. PMID:22537571

Endoscopic stents have evolved dramatically over the past 20 years. With the introduction of uncovered self-expanding metal stents in the early 1990s, they are primarily used to palliate symptoms of malignant obstruction in patients with inoperable gastrointestinal (GI) cancer. At present, stents have emerged as an effective, safe, and less invasive alternative for the treatment of malignant GI obstruction. Clinical decisions about stent placement should be made based on the exact understanding of the patient's condition. These recommendations based on a critical review of the available data and expert consensus are made for the purpose of providing endoscopists with information about stent placement. These can be helpful for management of patients with inoperable cancer or various nonmalignant conditions in the upper GI tract. PMID:23964331

To investigate the efficacy of combined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication for cardiochalasia patients. Clinical data of 11 cardiochalasia patients who underwent combined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication by the same medical team from January 2015 to December 2016 at The Second Hospital of Jilin University were retrospectively analyzed. The procedure was as follows: an incision was made in the anterior wall of esophagus and dissection of esophageal muscular layer was performed, then the bulged esophageal mucosa was covered by the fundus after 180 degrees fold to the right (fundoplication), finally the gastric fundus was joined to the right diaphragmatic foot by 3 to 5 knotted suture. The efficacy was judged by the Eckardt scoring standard: the postoperative Eckardt score ≤3 points indicated effectiveness, otherwise the treatment was invalid. Combined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication was completed successfully in all the 11 patients without any subsequent laparotomy and death. The mean operative time was 85 (78 to 137) min, blood loss was 15 (5 to 35) ml, and no upper digestive tract perforation occurred. The mean postoperative hospital stay was 7.0(6 to 9) d. After the operation, the pressure of lower esophageal sphincter decreased significantly compared to that before operation [(5.31±6.23) mmHg vs. (35.72±17.13) mmHg, P<0.05], and the Eckardt score decreased significantly as well (0.53±0.56 vs. 6.17±1.17, P<0.05). During the follow-up of 2 to 23 months, there was no postoperative mortality. One case experienced mild gastroesophageal reflux 6 months after operation, and another patient had recurrent dysphagia 17 months after operation, who both were improved after receiving proton pump inhibitors or gastric dynamic drugs, and balloon dilation. Combined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication is an effective and safe surgical procedure for cardiochalasia with minimal invasion and fast recovery.

Capsule endoscopy was invented to visualize the entire small intestine in a non- invasive manner in adults. 1 y, 9 mo-old boy presented with generalized edema for last 3 months. His routine investigations, including the upper gastrointestinal endoscopy, colonoscopy, and contrast enhanced computed tomography scan (CECT) were normal. In view of clinical suspicion of protein losing enteropathy, we planned capsule endoscopy. The capsule was not passed even after 3 weeks. Laparoscopy revealed impacted capsule in a dilated intestinal loop proximal to an ileal stricuture. Capsule endoscopy should be used judiciously in children.

Background and study aims TC-325 (Hemospray, Cook Medical) is a powder agent for endoscopic hemostasis in patients with upper gastrointestinal bleeding (UGIB). Although most publications are based on case-reports and retrospective studies, data on efficacy are promising. Here we report our experience with TC-325 for diffuse or refractory UGIB. Patients and methods Data on patients receiving TC-325 for endoscopic hemostasis from November 2013 to February 2017 at our center were analyzed retrospectively. Primary endpoints were technical success (successful immediate hemostasis) and clinical success (effective hemostasis and no recurrent bleeding). Secondary endpoints were recurrent bleeding within 3 and 7 days, hospital mortality and TC-325 associated complications. TC-325 was used for bleeding not amenable to standard endoscopic treatment (e. g. diffuse bleeding) or as salvage therapy after failure of conventional methods Results Fifty-two patients received TC-325 treatment. Most of the patients were treated for peptic ulcer bleeding (18/52 patients, 34.6 %) and post-interventional bleeding (13/52 patients, 25 %). Hemospray was used in 23/52 (44.2 %) patients as monotherapy and in 29/52 (55.8 %) patients as a salvage therapy. Application of the powder on the bleeding source was successful in all patients with no therapy-related adverse events (AEs). Immediate hemostasis was achieved in 51/52 (98.1 %) patients. Recurrent bleeding within 3 and 7 days was observed in 22/51 and 25/51 patients respectively (43.1 % and 49 %). The overall clinical success was 56.9 % on day 3 and 51 % on day 7. Total mortality was 15.4 % (8 patients), bleeding associated mortality was 3.8 % (2 patients). There were no therapy-related AEs. Conclusions TC-325 showed a high technical success rate as monotherapy for bleeding sources not amenable to standard methods or as an “add-on” therapy after unsuccessful hemostasis. However, rebleeding was frequent in this cohort and further studies are warranted to exactly define a treatment algorithm for TC-325 use. PMID:29124127

Gastrointestinal bleeding is a well-known risk of systemic anticoagulation. However, bleeding in the setting of supratherapeutic anticoagulation may have a milder natural history than unprovoked bleeding. It is a common clinical gestalt that endoscopy is common, but bleeding source identification or intervention is uncommon, yet few data exist to inform this clinical impression. Consequently, we sought to examine our institutional experience with gastrointestinal bleeding in the setting of supratherapeutic international normalized ratio (INR) with the aim of identifying predictors of endoscopically identifiable lesions, interventions, and outcomes. A retrospective review was conducted at a tertiary referral academic medical center to identify patients presenting with gastrointestinal bleeding in the setting of warfarin and a supratherapeutic INR (>3.5) who underwent an endoscopic procedure. Relevant clinical covariates, endoscopic findings, need for intervention, and outcomes were collected by review of the medical record. Logistic regression adjusting for potential confounders identified predictors of endoscopically significant lesions as well as intervention and outcomes. A total of 134 patients with INR 3.5 or greater (mean 5.5, range 3.5-17.1) presented with symptoms of gastrointestinal bleeding, most commonly as melena or symptomatic anemia. Antiplatelet agents were used by 54% of patients, and 60% of patients were on concomitant acid suppression on admission. Procedures included esophagogastroduodenoscopy (upper endoscopy; EGD) (n = 128), colonoscopy (n = 73), and video capsule endoscopy (n = 32). Active bleeding at first EGD or colonoscopy was found in only 19 patients (18%), with endoscopic intervention in only 26 patients (25%). At a critical threshold of INR 7.5 at presentation, the likelihood of finding an endoscopically significant lesion fell to <20%. On multivariate logistic regression, concomitant antiplatelet therapy (odds ratio [OR] 2.59; 95% confidence interval [CI], 1.13-5.94), timing of EGD within 12 hours of presentation (OR 3.71; 95% CI, 1.05-13.08), and INR level (OR 0.79; 95% CI, 0.64-0.98) were the only significant independent predictors of identifying a source of bleeding. A risk score incorporating these covariates performed modestly in identifying risk of significant finding on EGD (area under the curve 0.68). We found no association between identification of a significant lesion at EGD and future readmission for gastrointestinal bleeding. This study demonstrates that the relationship between INR elevation and identification of a bleeding source or endoscopic intervention at EGD are indeed antiparallel. Concomitant antiplatelet therapy increases the likelihood of bleeding source identification and intervention, as does EGD within 12 hours of presentation. However, regardless of source identification or endoscopic intervention, important clinical outcomes were unchanged, suggesting that decisions about endoscopy should be made on a case-by-case basis, particularly in patients with INR > 7.5. Future prospective studies on appropriate indications and timing of endoscopy in such patients are warranted. Copyright © 2016 Elsevier Inc. All rights reserved.

AIM: To compare the therapeutic effects of proton pump inhibitors vs H2 receptor antagonists for upper gastrointestinal bleeding in patients after successful endoscopy. METHODS: We searched the Cochrane library, MEDLINE, EMBASE and PubMed for randomized controlled trials until July 2014 for this study. The risk of bias was evaluated by the Cochrane Collaboration’s tool and all of the studies had acceptable quality. The main outcomes included mortality, re-bleeding, received surgery rate, blood transfusion units and hospital stay time. These outcomes were estimated using odds ratios (OR) and mean difference with 95% confidence interval (CI). RevMan 5.3.3 software and Stata 12.0 software were used for data analyses. RESULTS: Ten randomized controlled trials involving 1283 patients were included in this review; 678 subjects were in the proton pump inhibitors (PPI) group and the remaining 605 subjects were in the H2 receptor antagonists (H2RA) group. The meta-analysis results revealed that after successful endoscopic therapy, compared with H2RA, PPI therapy had statistically significantly decreased the recurrent bleeding rate (OR = 0.36; 95%CI: 0.25-0.51) and receiving surgery rate (OR = 0.29; 95%CI: 0.09-0.96). There were no statistically significant differences in mortality (OR = 0.46; 95%CI: 0.17-1.23). However, significant heterogeneity was present in both the numbers of patients requiring blood transfusion after treatment [weighted mean difference (WMD), -0.70 unit; 95%CI: -1.64 - 0.25] and the time that patients remained hospitalized [WMD, -0.77 d; 95%CI: -1.87 - 0.34]. The Begg’s test (P = 0.283) and Egger’s test (P = 0.339) demonstrated that there was no publication bias in our meta-analysis. CONCLUSION: In patients with upper gastrointestinal bleeding after successful endoscopic therapy, compared with H2RA, PPI may be a more effective therapy. PMID:26034370

Background and study aims Self-expandable metallic stents (SEMS) have been increasingly used in benign conditions (e. g. strictures, fistulas, leaks, and perforations). Fully covered SEMS (FSEMS) were introduced to avoid undesirable consequences of partially covered SEMS (PSEMS), but come with higher risk of stent migration. Endoscopic suturing (ES) for stent fixation has been shown to reduce migration of FSEMS. Our aim was to compare the outcomes of FSEMS with ES (FS/ES) versus PSEMS in patients with benign upper gastrointestinal conditions. Patients and methods We retrospectively identified all patients who underwent stent placement for benign gastrointestinal conditions at seven US tertiary-care centers. Patients were divided into two groups: FSEMS with ES (FS/ES group) and PSEMS (PSEMS group). Clinical outcomes between the two groups were compared. Results A total of 74 (FS/ES 46, PSEMS 28) patients were included. On multivariable analysis, there was no significant difference in rate of stent migration between FS/ES (43 %) and PSEMS (15 %) (adjusted odds ratio 0.56; 95 % CI 0.15 – 2.00). Clinical success was similar [68 % vs. 64 %; P = 0.81]. Rate of adverse events (AEs) was higher in PSEMS group [13 (46 %) vs. 10 (21 %); P = 0.03). Difficult stent removal was higher in the PSEMS group (n = 5;17 %) vs. 0 % in the FS/ES group; P = 0.005. Conclusions The proportion of stent migration of FS/ES and PSEMS are similar. Rates of other stent-related AEs were higher in the PSEMS group. PSEMS was associated with tissue ingrowth or overgrowth leading to difficult stent removal, and secondary stricture formation. Thus, FSEMS with ES for stent fixation may be the preferred modality over PSEMS for the treatment of benign upper gastrointestinal conditions. PMID:29404384

AIM To systematically review the syndrome of giant gastric lipomas, report 2 new illustrative cases. METHODS Literature systematically reviewed using PubMed for publications since 1980 with following medical subject heading/keywords: (“giant lipoma”) AND (“gastric”) OR [(“lipoma”) and (“gastric”) and (“bleeding”)]. Two authors independently reviewed literature, and decided by consensus which articles to incorporate. Computerized review of pathology/endoscopy records at William Beaumont Hospitals, Royal Oak and Troy, Michigan, January 2005-December 2015, revealed 2 giant gastric lipomas among 117110 consecutive esophagogastroduodenoscopies (EGDs), which were thoroughly reviewed, including re-review of original endoscopic photographs, radiologic images, and pathologic slides. RESULTS Giant gastric lipomas are extremely rare: 32 cases reported since 1980, and 2 diagnosed among 117110 consecutive EGDs. Average patient age = 54.5 ± 17.0 years old (males = 22, females = 10). Maximal lipoma dimension averaged 7.9 cm ± 4.1 cm. Ulcerated mass occurred in 21 patients. Lipoma locations: antrum-17, body-and-antrum-4, antrum-intussuscepting-into-small-intestine-3, body-2, fundus-1, and unspecified-5. Intramural locations included submucosal-22, subserosal-2, and unspecified-8. Presentations included: acute upper gastrointestinal (UGI) bleeding-19, abdominal pain-5, nausea/vomiting-5, and asymptomatic-3. Symptoms among patients with UGI bleeding included: weakness/fatigue-6, abdominal pain-4, nausea/vomiting-4, early-satiety-3, dizziness-2, and other-1. Their hemoglobin on admission averaged 7.5 g/dL ± 2.8 g/dL. Patients with GI bleeding had significantly more frequently ulcers than other patients. EGD was extremely helpful diagnostically (n = 31 patients), based on characteristic endoscopic findings, including yellowish hue, well-demarcated margins, smooth overlying mucosa, and endoscopic cushion, tenting, or naked-fat signs. However, endoscopic mucosal biopsies were mostly non-diagnostic (11 of 12 non-diagnostic). Twenty (95%) of 21 abdominal CTs demonstrated characteristic findings of lipomas, including: well-circumscribed, submucosal, and homogeneous mass with attenuation of fat. Endoscopic-ultrasound showed characteristic findings in 4 (80%) of 5 cases: hyperechoic, well-localized, mass in gastric-wall-layer-3. Transabdominal ultrasound and UGI series were generally less helpful. All 32 patients underwent successful therapy without major complications or mortality, including: laparotomy and full-thickness gastric wall resection of tumor using various surgical reconstructions-26; laparotomy-and-enucleation-2; laparoscopic-transgastric-resection-2; endoscopic-mucosal-resection-1, and other-1. Two new illustrative patients are reported who presented with severe UGI bleeding from giant, ulcerated, gastric lipomas. CONCLUSION This systematic review may help standardize the endoscopic and radiologic evaluation and therapy of patients with this syndrome. PMID:28852321

This study aims to determine the incidence, etiology, and management options for symptomatic gastric obstruction caused by axially twisted sleeve gastrectomy. In this retrospective study, we reviewed medical charts of all morbidly obese patients who underwent laparoscopic sleeve gastrectomy. Patients who developed gastric obstruction symptoms and were diagnosed with twisted sleeve gastrectomy were identified and included in this study. From October 2005 to December 2015, there are 3634 morbidly obese patients who underwent laparoscopic sleeve gastrectomy (LSG). Eighty-six (2.3%) patients developed symptoms of gastric obstruction. Forty-five (1.23%) patients were included in this study. The mean time of presentation was 59.8 days after surgery. Upper GI contrast study was done routinely, and it was positive for axial twist in 37 (82%) patients. Abdominal CT with oral and IV contrast was done in eight (18%) when swallow study was equivocal. Endoscopic treatment was successful in 43 patients (95.5%). Sixteen patients were successfully managed by endoscopic stenting, and 29 patients had balloon dilation. The average numbers of dilation sessions were 1.7. Out of these 29 patients, 18 responded well to a single session of dilatation and did not require any further dilatation sessions. Two patients who failed to respond to three subsequent sessions of balloon dilation underwent laparoscopic adhesiolysis and gastropexy. Endoscopic stenting is an effective tool in management of axial rotation of sleeved stomach. Balloon dilation can also be effective in selected cases. Few cases might require laparoscopic adhesiolysis and gastropexy.

Colonoscopy allows for the inspection of the entire colon and provides the ability to perform a number of therapeutic operations during a single procedure. During a colonoscopic procedure, a tiny video camera at the tip of the endoscope generates a video signal of the internal mucosa of the colon. The video data are displayed on a monitor for real-time analysis by the endoscopist. Other endoscopic procedures include upper gastrointestinal endoscopy, enteroscopy, bronchoscopy, cystoscopy, and laparoscopy. However, a significant number of out-of-focus frames are included in this type of videos since current endoscopes are equipped with a single, wide-angle lens that cannot be focused. The out-of-focus frames do not hold any useful information. To reduce the burdens of the further processes such as computer-aided image processing or human expert"s examinations, these frames need to be removed. We call an out-of-focus frame as non-informative frame and an in-focus frame as informative frame. We propose a new technique to classify the video frames into two classes, informative and non-informative frames using a combination of Discrete Fourier Transform (DFT), Texture Analysis, and K-Means Clustering. The proposed technique can evaluate the frames without any reference image, and does not need any predefined threshold value. Our experimental studies indicate that it achieves over 96% of four different performance metrics (i.e. precision, sensitivity, specificity, and accuracy).

Proton-pump inhibitors have been used for at least two decades. They are among the most commonly sold drugs in the world. However, some controversy remains about the indications for their use and the consequences of their prolonged use. To evaluate and compare the endoscopic and histopathologic gastric changes in chronic users of proton-pump inhibitors to changes in non-users. A prospective study performed at a tertiary Public Hospital involving 105 patients undergoing upper-gastrointestinal endoscopy. Subjects included 81 proton-pump inhibitor users and 24 non-users (control group). Biopsies of the antral-type mucosa, the antral-fundic transition, and the fundus were evaluated by the Sydney System. The presence of erosion or ulceration, lymphatic follicles, reactive gastropathy, and polypoid or epithelial hyperplasia was also determined. Serum levels of gastrin were measured. We found two polyps, one in each group, both of which were negative for Helicobacter pylori. There were two cases of parietal cell hyperplasia in users of proton-pump inhibitors. Gastrin was elevated in 28 users of proton-pump inhibitors and in four members of the control group. We did not find statistically significant differences in the endoscopic or histopathologic findings between the two groups. Chronic use of proton-pump inhibitors for the duration examined was not associated with significant gastric changes. An interesting finding was that the 4 chronic users of proton-pump inhibitors who had serum gastrin levels above 500 pg/mL also had positive serology for Chagas disease.

We developed an ultrahigh speed endoscopic swept source optical coherence tomography (OCT) system for clinical gastroenterology using a vertical-cavity surface-emitting laser (VCSEL) and micromotor based imaging catheter, which provided an imaging speed of 600 kHz axial scan rate and 8 μm axial resolution in tissue. The micromotor catheter was 3.2 mm in diameter and could be introduced through the 3.7 mm accessory port of an endoscope. Imaging was performed at 400 frames per second with an 8 μm spot size using a pullback to generate volumetric data over 16 mm with a pixel spacing of 5 μm in the longitudinal direction. Three-dimensional OCT (3D-OCT) imaging was performed in patients with a cross section of pathologies undergoing standard upper and lower endoscopy at the Veterans Affairs Boston Healthcare System (VABHS). Patients with Barrett's esophagus, dysplasia, and inflammatory bowel disease were imaged. The use of distally actuated imaging catheters allowed OCT imaging with more flexibility such as volumetric imaging in the terminal ileum and the assessment of the hiatal hernia using retroflex imaging. The high rotational stability of the micromotor enabled 3D volumetric imaging with micron scale volumetric accuracy for both en face and cross-sectional imaging. The ability to perform 3D OCT imaging in the GI tract with microscopic accuracy should enable a wide range of studies to investigate the ability of OCT to detect pathology as well as assess treatment response.

Natural orifice transluminal endoscopic surgery (NOTES) makes it possible to perform intraperitoneal surgical procedures with a minimal number of access points in the abdominal wall. Currently, it is not possible to perform these interventions without the help of abdominal wall entryways, so these procedures are hybrids fusing minilaparoscopy and transluminal endoscopic surgery. This report presents a prospective clinical series of 25 patients who underwent transvaginal hybrid cholecystectomy for cholelithiasis. The study comprised a clinical series of 25 consecutive nonrandomized women who underwent a fusion transvaginal NOTES and minilaparoscopy procedure with two trocars for cholelithiasis: one 5-mm umbilical trocar and one 3-mm trocar in the upper left quadrant. The study had no control group. The scheduled surgical intervention was performed for all 25 women. No intraoperative complications occurred. One patient had mild hematuria that resolved in less than 12 h, but no other complications occurred during an average follow-up period of 140 days. Of the 25 women, 20 were discharged in 24 h, and 5 were discharged less than 12 h after the procedure. Hybrid transvaginal cholecystectomy, combining NOTES and minilaparoscopy, is a good surgical model for minimally invasive surgery. It can be performed in surgical settings where laparoscopy is practiced regularly using the instruments normally used for endoscopy and laparoscopic surgery. Due to the reproducibility of the intervention and the ease of vaginal closure, hybrid transvaginal cholecystectomy will permit further development of NOTES in the future.

We describe the design and performance tested during six years of clinical trials of a fluorescence endoscope for the detection and delineation of cancers in several hollow organs. The apparatus is based on the imaging of the laser-induced fluorescence that differs between a tumor and its surrounding normal tissue. The tests are carried out in the upper aerodigestive tract, the tracheobronchial tree, the esophagus, and the colon. In the three former cases an exogenous dye is used (Photofrin II), whereas in the latter case fluorescein molecules conjugated with monoclonal antibodies directed against carcinoembryonic antigen are injected. The decrease of native tissue autofluorescence observed in early cancers is also used for detecting lesions in the tracheobronchial tree. The fluorescence contrast between the tumor and surrounding normal tissue is enhanced by real time image processing. This is done by simultaneously recording the fluorescence image in two spectral domains, after which these two images are digitized and manipulated with a mathematical operator (look-up table) at video frequency. Moreover, the device that is described below allows for an immediate observation of the endoscopic area under white light illumination during fluorescence detection in order to localize the origin of the "positive" fluorescence signals. Typical results obtained in the tracheobronchial tree and in the colon are presented and the sources of false positives and false negatives are evaluated in terms of the fluorescent dye, tissue optical properties, and illumination optics.

The study compared the endoscopic anatomy of the transnasal and transoral approaches to the craniovertebral junction (CVJ). Structures examined and compared with both the straight and angled telescopes in 10 cadaveric specimens included the pharyngeal walls and adjacent musculature, resected anterior arch of the axis and odontoid, cruciform, axial, and apical ligaments, clival and dural openings, and the intradural exposure. There is considerable overlap at the pharyngeal level in the structures that can be viewed by the transoral and transnasal routes. The transoral approach provides a wider corridor with less restricted manipulation of instruments than the transnasal approach, but the transnasal approach provides a better view of the clivus, upper part of the CVJ, and the structures posterior to the removed odontoid and anterior arch of C1. Combining the two approaches provides significantly better access to the midline anterior CVJ than either approach alone, allows the scopes to be advanced in one cavity and the surgical instruments in the other cavity, and reduces the need to split the palate, tongue, or mandible in order to reach the target area. The transnasal approach also allows access to the superior part of the occipital condyles, paraclival areas, and hypoglossal canals without removal of the condyles, but these structures can be exposed by the transoral route only after at least partial removal of the condyles. The endoscopic transoral and transnasal approaches to the CVJ should be viewed as complementary routes as opposed to strict alternatives. Copyright © 2010 Elsevier Inc. All rights reserved.
Hemobilia: An Uncommon But Notable Cause of Upper Gastrointestinal Bleeding.

A literature review to improve practitioners' knowledge and performance concerning the epidemiology, diagnosis, and management of hemobilia. A search of Pubmed, Google Scholar, and Medline was conducted using the keyword hemobilia and relevant articles were reviewed and analyzed. The findings pertaining to hemobilia etiology, investigation, and management techniques were considered and organized by clinicians practiced in hemobilia. The majority of current hemobilia cases have an iatrogenic cause from either bile duct or liver manipulation. Blunt trauma is also a significant cause of hemobilia. The classic triad presentation of right upper quadrant pain, jaundice, and upper gastrointestinal bleeding is rarely seen. Computed tomography and magnetic resonance imaging are the preferred diagnostic modalities, and the preferred therapeutic management includes interventional radiology and endoscopic retrograde cholangiopancreatography. Surgery is rarely a therapeutic option. With advances in computed tomography and magnetic resonance imaging technology, diagnosis with these less invasive investigations are the favored option. However, traditional catheter angiography is still the gold standard. The management of significant hemobilia is still centered on arterial embolization, but arterial and biliary stents have become accepted alternative therapies.

Despite new treatment methods, upper gastrointestinal bleeding remains challenging. Samen-ista emulsion is a new agent based on traditional medicine with coagulant properties. The efficacy and safety of Samen-ista were assessed in cutaneous and mucosal bleeding animal models. Coagulant properties of Samen-ista were evaluated using mice tail bleeding assay, marginal ear vein and upper gastrointestinal mucosal bleeding times in rabbits. After 7 days, clinical signs, mortality and end-organ (kidney, liver, lung, brain and gastric mucosa) histopathological changes were also examined. Samen-ista dose-dependently decreased mean cutaneous tail (128 vs. 14 s) and marginal ear vein (396 vs. 84 s) bleeding times. Rabbit's upper gastrointestinal bleeding time was also significantly decreased (214 vs. 15.8 s) upon Samen-ista local endoscopic application. Treatment with Samen-ista for 7 days did not cause any mortality, abnormal signs of bleeding, changes in appetite or significant histopathologicl changes. Samen-ista emulsion is well tolerated and highly effective in achieving hemostasis in cutaneous and mucosal bleeding animal models.

The aim of this study was to describe a minimally invasive laparoscopic jejunostomy (Lap-J) technique for obstruction due to upper gastrointestinal malignancies and evaluate the nutritional benefit of Lap-J during neoadjuvant chemotherapy (NAC) in cases with obstructing esophageal cancer. Under general anesthesia, the jejunum 20–30 cm distant from the Treitz ligament was pulled out through an extended umbilical laparoscopic incision and a jejunal tube was inserted to 30 cm. The loop of bowel was gently returned to the abdomen and the feeding tube was drawn through the abdominal wall via the left lower incision. The jejunum was then laparoscopically sutured to the anterior abdominal wall. Lap-J was performed in 26 cases. The median operative time was 82 min. The postoperative course was uneventful. Lap-J prior to NAC was not associated with a decrease in body weight or serum total protein during NAC, compared with patients who received NAC without Lap-J. This minimally invasive jejunostomy technique may be particularly useful in patients in whom endoscopic therapy is not feasible due to obstruction from upper gastrointestinal malignancies.

Urea breath test (UBT) using an infrared spectral analyzer is widely used for non-invasive and rapid detection of gastric Helicobacter spp. in human, but not veterinary medicine. The main purposes of this study were to determine the reference range of the UBT in dogs and to evaluate its clinical usefulness. To address the first aim, 6 healthy laboratory beagles were subjected to UBT and upper gastrointestinal endoscopy. Gastric endoscopic biopsy samples from the antrum, corpus and fundus were examined for Helicobacter spp. by polymerase chain reaction (PCR) testing, rapid urease test (RUT), histology and cytology. Amoxicillin, metronidazole and omeprazole were given to infected dogs for 14 days, and dogs that became Helicobacter-negative were used to determine the reference range for UBT. To address the second aim, 32 canine patients underwent UBT before upper gastrointestinal endoscopy, and the sensitivity and specificity of UBT were calculated based on our newly determined reference range using PCR as the gold standard for detection of Helicobacter spp. Initially, all 6 laboratory beagles were infected in all gastric regions and became uninfected after eradication. The mean ± 2 SD UBT value after eradication was 0.6 ± 1.8‰, and the reference range for UBT was determined to be less than 2.5‰. UBT was completed successfully in 27 patients. Using our reference range, UBT displayed 89% (16/18) sensitivity and 89% (8/9) specificity, indicating that UBT was quite useful for the detection of gastric Helicobacter spp. infection in dogs.

Although endoscopic submucosal dissection (ESD) is a widely accepted treatment for early gastric cancer (EGC), there is no consensus regarding the management of positive horizontal margin (HM) despite en bloc ESD. The aim of the current study was to identify the risk factors and optimal management of positive HM in EGCs resected by en bloc ESD. A total of 890 consecutive patients with 1,053 intramucosal EGCs resected by en bloc ESD between April 2005 and June 2011. Clinicopathological data were retrieved retrospectively to assess the positive HM rate, local recurrence rate, risk factors for positive HM, and outcomes of treatment for local recurrent tumor. Positive HM was defined as a margin with direct tumor invasion (type A), the presence of cancerous cells on either end of 2-mm-thick cut sections (type B), or an unclear tumor margin resulting from crush or burn damage (type C). The positive HM rate was 2.0% (21/1,053). The local recurrence rate was 0.3% (3/1,053). All local recurrent tumors were intramucosal carcinomas, and were resected curatively by re-ESD. Multivariate analysis with logistic regression showed tumor location in the upper third of the stomach and lesions not matching the absolute indication to be independent risk factors for positive HM. The risk factors for HM positivity in cases of EGC resected by en bloc ESD are tumor location in the upper third of the stomach and dissatisfaction of the absolute indication for curative ESD.

The development of gastric dysplasia and neoplasia in patients with pernicious anaemia has been evaluated in a prospective clinical and endoscopic follow up study. After initial screening of 80 patients between 1978 and 1980, one patient underwent total gastrectomy for a gastric malignancy and 12 were kept under surveillance and underwent endoscopy at a mean interval of 14 months. In the remaining 67 patients further investigation was attempted six to seven years after the initial investigation. The continuous follow up study identified carcinoids in one patient and an adenoma with severe dysplasia in a further patient. The grade and site of mucosal dysplasia differed from one investigation to the next, but no overall progression was observed. Of the 79 patients, eight had died by the time of the reinvestigation, two of unknown cause and six of causes unrelated to pernicious anaemia. In 38 of the remaining 71 patients, clinical data only were available, with no evidence of new gastric malignancy. In 27 patients it was possible to perform an upper gastrointestinal endoscopy, when no change in the degree of dysplasia was detected. In six patients no follow up information was obtainable. In conclusion, patients with pernicious anaemia should be investigated by upper gastrointestinal endoscopy soon after diagnosis. Polyps should be removed wherever possible. In the presence of severe mucosal dysplasia or polyps that are not removed, frequent reinvestigation should be performed, provided the patient is eligible for gastric surgery. In the remaining patients, follow up endoscopies at about five year intervals would seem sufficient. PMID:2083855

The present study aimed to clarify the features and management of non-variceal upper gastrointestinal bleeding (UGIB) in Japanese patients taking antithrombotic agents. We retrospectively investigated the medical records of 560 patients who underwent emergency endoscopy for UGIB from 2002 to 2013. The patients were divided into two groups: group A, antithrombotic agent use; and group NA, no antithrombotic agent use. We compared clinical characteristics, comorbidities, and causes of UGIB between the groups. We also investigated management with antithrombotics. Of 560 patients with UGIB, 27.5% were taking antithrombotics, and this proportion gradually increased during the study period. Mean hemoglobin levels on admission were significantly lower in group A (8.0 ± 1.7 g/dL) than in group NA (8.9 ± 2.9 g/dL) (P < 0.001). Patients in group A developed more gastric ulcers and multiple ulcers than did patients in group NA. Incidence of Forrest Ia-type bleeding was lower in group A than in group NA (P < 0.001), and the rate of endoscopic hemostasis was significantly higher in group A (98.7%) than in group NA (94.3%) (P = 0.022). After the release of the 2012 Japan Gastroenterological Endoscopy Society guidelines, the antithrombotic agent cessation periods were significantly shortened (P < 0.001). Among patients with UGIB, those taking antithrombotics exhibited more severe clinical signs. However spurting hemorrhage was rare. Antithrombotics may be resumed early after endoscopic hemostasis. © 2014 The Authors. Digestive Endoscopy © 2014 Japan Gastroenterological Endoscopy Society.

Numerous publications on the successful application of prolit super septo ( Greenwood, RF) in metaphylaxis of urolithiasis after extracorporeal shockwave lithotripsy, and in infectiousand inflammatory diseases of the upper and lower urinary tract gave rise to research aimed at investigating the efficacy and safety of long-term use of prolit super septo in patients undergoing various transurethral and percutaneous interventions. From September 2012, to March 2013, 894 transurethral and percutaneous endoscopic interventions were performed. The main group (n=450) consisted of patients treating with prolit super septo at a dose of 2 capsules 2 times a day for a one month in addition to standard uroantiseptic therapy after endourological interventions. The control group (n=444) consisted of patients receiving standard therapy for the same period after same interventions. The evaluation of patients both main and control group was focused on pyuria, daily diuresis, symptoms and quality of life of patients. It was found that after transurethral surgery of the lower urinary tract, the use of prolit super septo reduces the severity of irritative symptoms, improves the quality of life, reduces the leucocyturia, and increases the diuresis. Application of prolit super septo after operations on the upper urinary tract leads to a decrease of leucocyturia, increase of dieresis, and improves the discharge of residual fragments. In patients with oxalate and urate calculi, persistent increase in the pH of urine was noteda, which may be a part of metaphylaxis of urolithiasis. Adverse effects associated with taking of prolit super septo were not observed.

Gastrointestinal foreign bodies (FB) are comprised of food bolus impaction and intentionally or unintentionally ingested or inserted true FB. Food bolus impaction and true FB ingestion represent a recurrent problem and a true challenge in gastrointestinal endoscopy. More than 80-90% of the ingested true FB will pass spontaneously through the gastrointestinal tract without complications. However, in 10-20% of the cases an endoscopic intervention is deemed necessary. True FB ingestion has its greatest incidence in children, psychiatric patients and prisoners. On the other hand, food bolus impaction typically occurs in the elderly population with an underlying esophageal pathology. The most serious situations, with higher rates of complications, are associated with prolonged esophageal impaction, ingestion of sharp and long objects, button batteries and magnets. Physicians should recognize early alarm symptoms, such as complete dysphagia, distressed patients not able to manage secretions, or clinical signs of perforation. Although many papers are yearly published regarding this subject, our knowledge is mainly based on case-reports and retrospective series. Herein, the authors summarize the existing evidence and propose an algorithm for the best approach to FB ingestion.
Endoscopic duodenal perforation: surgical strategies in a regional centre
2014-01-01
Background Duodenal perforation is an uncommon complication of endoscopic retrograde cholangio-pancreatography (ERCP) and a rare complication of upper gastrointestinal endoscopy. Most are minor perforations that settle with conservative management. A few perforations however result in life-threatening retroperitoneal necrosis and require surgical intervention. There is a relative paucity of references specifically describing the surgical interventions required for this eventuality. Methods Five cases of iatrogenic duodenal perforation were ascertained between 2002 and 2007 at Cairns Base Hospital. Clinical features were analyzed and compared, with reference to a review of ERCP at that institution for the years 2005/2006. Results One patient recovered with conservative management. Of the other four, one died after initial laparotomy. The other three survived, undergoing multiple procedures and long inpatient stays. Conclusions Iatrogenic duodenal perforation with retroperitoneal necrosis is an uncommon complication of endoscopy, but when it does occur it is potentially life-threatening. Early recognition may lead to a better outcome through earlier intervention, although a protracted course with multiple procedures should be anticipated. A number of surgical techniques may need to be employed according to the individual circumstances of the case. PMID:24461069

The present paper describes a case of hemorrhagic cholecystitis in a patient on maintenance dialysis. The patient presented with right upper quadrant abdominal pain. Computed tomography revealed swelling of the gallbladder, high- and isodensity contents of the gallbladder, and high-density stone in the gallbladder neck. He was hospitalized for suspected acute cholecystitis. After hospitalization, his levels of total bilirubin, aspartate aminotransferase, and alanine aminotransferase increased. T2-weighted magnetic resonance imaging showed low-intensity contents expanded to include a wide area from the common bile duct to the cystic duct and gallbladder neck. Endoscopic retrograde cholangiopancreatography revealed clotting from the duodenal papilla. After cannulation of the bile duct, old blood and pus began to flow from the mammary papilla, and an endoscopic nasobiliary drainage tube was placed. After his liver function had improved, the patient underwent laparoscopic cholecystectomy. His sample revealed that the gallbladder was filled with blood clots and stones. His postoperative course was uneventful and he was discharged on day 19 after the procedure. Although hemorrhagic cholecystitis is rare, it should be considered as a differential diagnosis for patients on dialysis who have acute abdominal symptoms. PMID:29033767

TC-325 is a novel endoscopic hemostatic powder. Our aim was to describe a single-center experience with the use of TC-325 in the upper and lower gastrointestinal tract, while for the first time attempting to determine how long the powder remains on a lesion. The charts of consecutive patients receiving TC-325 therapy between July 2011 and July 2013 were reviewed retrospectively. Primary endpoints included immediate hemostasis and early rebleeding (≤ 72 hours). Overall, 60 patients received 67 treatments with TC-325: 21 for nonmalignant nonvariceal upper gastrointestinal bleeding, 19 for malignant upper gastrointestinal bleeding, 11 for lower gastrointestinal bleeding, and 16 for intra-procedural bleeding. Immediate hemostasis was achieved in 66 cases (98.5 %), with 6 cases (9.5 %) of early rebleeding. No serious adverse events were noted. No TC-325 powder was identified in the 11 patients who underwent second-look endoscopy, performed within 24 hours in 4 patients. TC-325 appears safe and effective for managing bleeding in the upper and lower gastrointestinal tract with a variety of causes. The time during which the powder remains in the gastrointestinal tract is short, with complete elimination from the gastrointestinal tract as early as within 24 hours after use. © Georg Thieme Verlag KG Stuttgart · New York.

Placement of self-expandable nitinol stents is useful for the treatment of esophageal and upper gastrointestinal (GI) obstruction. However, complications such as stent migration, tumor overgrowth, and bleeding occur. Although stent migration and tumor overgrowth are well documented in previous studies, the occurrence of bleeding has not been fully evaluated. To evaluate the incidence, management strategies, and predictors of bleeding after placement of self-expandable nitinol stents in patients with esophageal and upper GI obstruction. We retrospectively reviewed the medical records and results of computed tomography and endoscopy of 1485 consecutive patients with esophageal and upper GI obstructions who underwent fluoroscopically guided stent placement. Bleeding occurred in 25 of 1485 (1.7%) patients 0 to 348 days after stent placement. Early stent-related bleeding occurred in 10 patients (40%) and angiographic embolization was used for 5/10. Late bleeding occurred in 15 patients (60%) and endoscopic hemostasis was used for 7/15. Twenty-two of 25 (88%) patients with bleeding had received prior radiotherapy and/or chemotherapy. Bleeding is a rare complication after placement of expandable nitinol stents in patients with esophageal and upper GI obstruction, but patients with early bleeding may require embolization for control. Care must be exercised on placing stents in patients who have received prior radiotherapy or chemotherapy. © The Foundation Acta Radiologica 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Our aim was to evaluate the biopsy quality of upper urinary tract urothelial transitional cell carcinoma with a new biopsy forceps (BIGopsy®, Cook Medical) compared to a classic biopsy forceps (Piranha®, Boston Scientific). From December 2009 to December 2011, 20 patients with upper urinary tract urothelial transitional cell carcinoma underwent conservative treatment endoscopically. All lesions were evaluated and biopsied with 3 Fr cup forceps using both types of forceps (BIGopsy and Piranha). A single pathologist blindly analyzed the specimens in order to determine the optimal biopsy for each patient. Specimen histopathology results were graded; however, they were staged if the lamina propria was not invaded (T1) or if the tumor was detected at the lamina propria (T1+). Of the 20 upper urinary tract lesions, 12 (60%) were in the renal pelvis, 3 (15%) in the upper calyx, 1 (5%) in the middle calyx, 1 (5%) in the lower calyx, 1 (5%) in the upper third of the ureter and 2 (10%) in the middle third of the ureter. We did not detect T1 in all biopsies. One patient had no valid biopsies by both forceps. A diagnosis of urothelial carcinoma was made in 17 BIGopsy biopsies compared to 7 Piranha biopsies. Despite the limited number of cases, our study demonstrated the advantage of the new forceps (BIGopsy) in obtaining a valid biopsy of upper urinary tract urothelial tumors. Therefore, we recommend it in evaluating this pathology for optimal treatment. © 2014 S. Karger AG, Basel.
Percutaneous Nephrolithotomy in Children
DeMarco, Romano T.
2011-01-01
The surgical management of pediatric stone disease has evolved significantly over the last three decades. Prior to the introduction of shockwave lithotripsy (SWL) in the 1980s, open lithotomy was the lone therapy for children with upper tract calculi. Since then, SWL has been the procedure of choice in most pediatric centers for children with large renal calculi. While other therapies such as percutaneous nephrolithotomy (PNL) were also being advanced around the same time, PNL was generally seen as a suitable therapy in adults because of the concerns for damage in the developing kidney. However, recent advances in endoscopic instrumentation and renal access techniques have led to an increase in its use in the pediatric population, particularly in those children with large upper tract stones. This paper is a review of the literature focusing on the indications, techniques, results, and complications of PNL in children with renal calculi. PMID:22013438

Obstruction in the upper airway can often cause reductions in breathing or gas exchange efficiency and lead to rest disorders such as sleep apnea. Imaging diagnosis of the obstruction region has been accomplished using computed tomography (CT) and magnetic resonance imaging (MRI). However CT requires the use of ionizing radiation, and MRI typically requires sedation of the patient to prevent motion artifacts. Long-range optical coherence tomography (OCT) has the potential to provide high-speed three-dimensional tomographic images with high resolution and without the use of ionizing radiation. In this paper, we present work on the development of a long-range OCT endoscopic probe with 1.2 mm OD and 20 mm working distance used in conjunction with a modified Fourier domain swept source OCT system to acquire structural and anatomical datasets of the human airway. Imaging from the bottom of the larynx to the end of the nasal cavity is completed within 40 s.

Insertion of a nasogastric tube is a routine procedure but during anaesthesia it is often difficult and time consuming. One hundred and sixty adults undergoing elective surgery under general anaesthesia were randomly divided into two groups. After induction of anaesthesia, neuromuscular blockade and tracheal intubation, a nasogastric tube was inserted through the nose with the head of the patient in the neutral position, either with or without prior inflation with air via a facepiece attached to a self-inflating bag applied firmly with the face. Insertion of the nasogastric tube was successful in 75/78 (96%) following inflation compared with 54/80 (68%) without inflation (p<0.001). In four patients receiving inflation, a fibreoptic endoscope was passed as far as the upper oesophageal sphincter; this revealed opening of the upper oesophageal sphincter during inflation.

Helicobacter pylori infection, non-steroidal anti-inflammatory drugs and peptic ulcer are considered as the major factors for upper gastrointestinal system bleeding. The objective of the study was to determine the sociodemographic and etiologic factors, management and outcome of patients with non-variceal upper gastrointestinal system bleeding in Turkey. Patients who admitted to hospitals with upper gastrointestinal system bleeding and in whom upper gastrointestinal endoscopy was performed were enrolled in this retrospective study. The detailed data of medical history, comorbid diseases, medications, admission to intensive care units, Helicobacter pylori infection, blood transfusion, upper gastrointestinal endoscopy, and treatment outcome were documented. The most frequent causes of bleeding (%) were duodenal ulcer (49.4), gastric ulcer (22.8), erosion (9.6), and cancer (2.2) among 1,711 lesions in endoscopic appearances of 1,339 patients from six centers. Seven hundred and four patients were evaluated for Helicobacter pylori infection and the test was positive in 45.6% of those patients. Comorbid diseases were present in 59.2% of the patients. The percentage of patients using acetylsalicylic acid and/or other non-steroidal anti-inflammatory drug was 54.3%. Bleeding was stopped with medical therapy in 66.9%. Only 3.7% of the patients underwent emergency surgery, and a 1.1% mortality rate was determined. Patients with upper gastrointestinal system bleeding were significantly older, more likely to be male, and more likely to use non-steroidal anti-inflammatory drugs. Though most of the patients were using gastro-protective agents, duodenal and gastric ulcers were the contributing factors in more than 70% of the upper gastrointestinal bleeding. The extensive use of non-steroidal anti-inflammatory drug is a hazardous health issue considering the use of these drugs in half of the patients.

AIM To determine if patients can localise dysphagia level determined endoscopically or radiologically and association of gender, age, level and pathology. METHODS Retrospective review of consecutive patients presenting to dysphagia hotline between March 2004 and March 2015 was carried out. Demographics, clinical history and investigation findings were recorded including patient perception of obstruction level (pharyngeal, mid sternal or low sternal) was documented and the actual level of obstruction found on endoscopic or radiological examination (if any) was noted. All patients with evidence of obstruction including oesophageal carcinoma, peptic stricture, Schatzki ring, oesophageal pouch and cricopharyngeal hypertrophy were included in the study who had given a perceived level of dysphagia. The upper GI endoscopy reports (barium study where upper GI endoscopy was not performed) were reviewed to confirm the distance of obstructing lesion from central incisors. A previously described anatomical classification of oesophagus was used to define the level of obstruction to be upper, middle or lower oesophagus and this was compared with patient perceived level. RESULTS Three thousand six hundred and sixty-eight patients were included, 42.0% of who were female, mean age 70.7 ± 12.8 years old. Of those with obstructing lesions, 726 gave a perceived level of dysphagia: 37.2% had oesophageal cancer, 36.0% peptic stricture, 13.1% pharyngeal pouches, 10.3% Schatzki rings and 3.3% achalasia. Twenty-seven point five percent of patients reported pharyngeal level (upper) dysphagia, 36.9% mid sternal dysphagia and 25.9% lower sternal dysphagia (9.5% reported multiple levels). The level of obstructing lesion seen on diagnostic testing was upper (17.2%), mid (19.4%) or lower (62.9%) or combined (0.3%). When patients localised their level of dysphagia to a single level, the kappa statistic was 0.245 (P < 0.001), indicating fair agreement. 48% of patients reporting a single level of dysphagia were accurate in localising the obstructing pathology. With respect to pathology, patients with pharyngeal pouches were most accurate localising their level of dysphagia (P < 0.001). With respect to level of dysphagia, those with pharyngeal level lesions were best able to identify the level of dysphagia accurately (P < 0.001). No association (P > 0.05) was found between gender, patient age or clinical symptoms with their ability to detect the level of dysphagia. CONCLUSION Patient perceived level of dysphagia is unreliable in determining actual level of obstructing pathology and should not be used to tailor investigations. PMID:28246477

INTRODUCTION Upper gastrointestinal endoscopy, traditionally performed in Cuba in specialized hospitals, was decentralized to the primary health care level in 2004 to make it more patient-accessible. OBJECTIVES Describe frequency and distribution of the principal symptomatic diseases of the upper gastrointestinal tract and their relation to the main risk factors associated with each in a sample of urban adults who underwent upper gastrointestinal endoscopy in primary care facilities in Havana in selected months of 2007. METHODS A multicenter cross-sectional study was conducted, including 3556 patients seen in the primary health care network of Havana from May through November 2007. The endoscopies were performed at the 22 polyclinics (community health centers) providing this service. Diagnostic quality and accuracy were assessed by experienced gastroenterologists using a validated tool. Patients responded to a questionnaire with clinical, epidemiologic, and sociodemographic variables. Univariate and multivariate analyses (unconditional logistical regression) were used to identify associated risk factors. The significance level was set at p < 0.05 (or confidence interval excluding 1.0). RESULTS The diagnoses were: gastritis (91.6%), duodenitis (57.8%), hiatal hernia (46.5%), esophagitis (25.2%), duodenal ulcer (15.8%), gastric ulcer (6.2%) and malignant-appearing lesions (0.4%). Overall prevalence of Helicobacter pylori infection was 58.4%. The main risk factors for duodenal ulcer were H. pylori infection (OR 2.70, CI 2.17-3.36) and smoking (OR 2.08, CI 1.68-2.58); and for gastric ulcer, H. pylori (OR 1.58, CI 1.17-2.15) and age ≥60 years (OR 1.78, CI 1.28-2.47). H. pylori infection was the main risk factor for gastritis (OR 2.29, CI 1.79-2.95) and duodenitis (OR 1.58, CI 1.38-1.82); and age ≥40 years for hiatal hernia (OR 1.57, CI 1.33-1.84). External evaluation was "very good" or "good" for 99.3% of endoscopic procedures and 97.9% of reports issued. CONCLUSIONS Gastrointestinal endoscopy performed in primary care yielded high quality results and important information about prevalence of the most common diseases of the upper GI tract and associated risk factors. This study provides a reference for new research and can inform objective recommendations for community-based interventions to prevent and control these diseases. The existence of a network of universally accessible diagnostic endoscopy services at the primary care level, will contribute to conducting further research.

Endoscopic tools have provided versatile examination and treatment for kidney stone procedures. Despite endourologists researching urinary stone disease using endoscopes to collect tissue, this tissue collection method is limited. Endoscopically removed tissues are small in size, restricting the types of genome-based examination possible. We investigated a new method of renal papilla biopsy and RNA extraction to establish a genomic research methodology for kidney stone disease. We conducted a prospective multi-institutional study and collected renal papilla specimens from consecutive percutaneous nephrolithotomy and ureteroscopy (URS) cases performed for removal of upper urinary tract stones. Renal papilla tissue was extracted using ureteroscopic biopsy forceps after stone removal. RNA was extracted using two different extraction kits, and their quantity and quality were examined. Additionally, the impact of biopsy on surgical complications was compared between cases performed with and without biopsy by matched case-control analysis adjusted for age, gender, body mass index, bilaterality, and stone burden. A total of 90 biopsies from 49 patients were performed, and the median duration between specimen collection and RNA extraction was 61 days. Both univariate and multivariate analyses showed BIGopsy ® forceps usage significantly increased the total yield (p = 0.004) and quality (p = 0.001 for A260/280, p = 0.004 for A260/A230) of extracted RNA. Extraction using the RNeasy Micro Kit ® also improved A260/A230, whereas reduced RNA integrity number of extracted RNA by univariate and multivariate analyses (p = 0.002 and p < 0.001, respectively). Moreover, matched case-control study demonstrated that endoscopic renal papilla biopsy caused no significant surgical complications, including bleeding, decreased stone clearance and hematocrit, and renal dysfunction. Biopsies during URS imparted an average of 20 minutes of procedure time over nonbiopsy cases. We demonstrate a safe methodology for optimal RNA extraction of renal papilla tissue. This technique will accelerate advanced genomic studies for kidney stone formers by facilitating larger tissue yields.

AIM To investigate the current management of gastric antral webs (GAWs) among adults and identify optimal endoscopic and/or surgical management for these patients. METHODS We reviewed our endoscopy database seeking to identify patients in whom a GAW was visualized among 24640 esophagogastroduodenoscopies (EGD) over a seven-year period (2006-2013) at a single tertiary care center. The diagnosis of GAW was suspected during EGD if aperture size of the antrum did not vary with peristalsis or if a “double bulb” sign was present on upper gastrointestinal series. Confirmation of the diagnosis was made by demonstrating a normal pylorus distal to the GAW. RESULTS We identified 34 patients who met our inclusion criteria (incidence 0.14%). Of these, five patients presented with gastric outlet obstruction (GOO), four of whom underwent repeated sequential balloon dilations and/or needle-knife incisions with steroid injection for alleviation of GOO. The other 29 patients were incidentally found to have a non-obstructing GAW. Age at diagnosis ranged from 30-87 years. Non-obstructing GAWs are mostly incidental findings. The most frequently observed symptom prompting endoscopic work-up was refractory gastroesophageal reflux (n = 24, 70.6%) followed by abdominal pain (n = 11, 33.4%), nausea and vomiting (n = 9, 26.5%), dysphagia (n = 6, 17.6%), unexplained weight loss, (n = 4, 11.8%), early satiety (n = 4, 11.8%), and melena of unclear etiology (n = 3, 8.82%). Four of five GOO patients were treated with balloon dilation (n = 4), four-quadrant needle-knife incision (n = 3), and triamcinolone injection (n = 2). Three of these patients required repeat intervention. One patient had a significant complication of perforation after needle-knife incision. CONCLUSION Endoscopic intervention for GAW using balloon dilation or needle-knife incision is generally safe and effective in relieving symptoms, however repeat treatment may be needed and a risk of perforation exists with thermal therapies.

Aim of the present study is to assess, according to the guidelines of the Maastricht Consensus Conference, the appropriateness and diagnostic yield of upper gastrointestinal endoscopy in an open-access endoscopy system, in order to evaluate the diffusion of knowledge about Helicobacter pylori among different types of physicians. Patients undergoing endoscopy because of dyspeptic symptoms were prospectively considered in 21 endoscopy services of Campania during two different 1-week periods in 1998 and 2001. The following data were recorded: age, sex, symptoms, history of peptic ulcer with regard to previous endoscopic or radiographic examinations and treatment, endoscopic diagnosis, and H. pylori status. The indication for endoscopy was evaluated according to Maastricht guidelines and current medical knowledge. In the two periods, 1998 and 2001, 706 and 520 patients were, respectively, considered. The two series were matched for demographic characteristics, symptoms, and endoscopic diagnosis. Endoscopy was considered not indicated in 398 patients (56.4%) in 1998 and in 265 patients (50.9%) in 2001 (p = NS). The majority of them, 288/398 (72.3%) in 1998 and 162/265 (61.1%) in 2001 (p = 0.001), had recently undergone endoscopy or radiology and empiric antisecretory treatment or eradication. They had been referred to endoscopy because of recurrence of symptoms or to assess healing. In 110 cases in 1998 (27.6%) and in 103 cases in 2001 (38.9%; p = 0.001) endoscopy was performed in dyspeptic patients younger than 45 years without alarm symptoms. 4 years after the Maastricht Conference, a large number of endoscopic examinations are not indicated and could be avoided following the Maastricht guidelines. In 2001, in comparison to 1998, a larger number of physicians are likely to investigate and treat correctly the H.-pylori-related diseases, but there are still some problems with the application of the 'test-and-treat policy'.

Gastroparesis is a functional disorder with a variety of symptoms that is characterized by delayed gastric emptying in the absence of mechanical obstruction. A recent series of retrospective studies has demonstrated that peroral endoscopic pyloromyotomy (G-POEM) is a promising endoscopic procedure for treating patients with refractory gastroparesis. The aim of this prospective study was to evaluate the feasibility, safety, and efficacy of G-POEM. 20 patients with refractory gastroparesis (10 diabetic and 10 nondiabetic) were prospectively included in the trial. Patients were treated by G-POEM after evaluation of pyloric function using an endoscopic functional luminal imaging probe. Clinical responses were evaluated using the Gastroparesis Cardinal Symptom Index (GCSI), and quality of life was assessed using the Patient Assessment of Upper Gastrointestinal Disorders - Quality of Life scale and the Gastrointestinal Quality of Life Index scores. Gastric emptying was measured using 4-hour scintigraphy before G-POEM and at 3 months. Feasibility of the procedure was 100 %. Compared with baseline values, G-POEM significantly improved symptoms (GCSI: 1.3 vs. 3.5; P < 0.001), quality of life, and gastric emptying (T½: 100 vs. 345 minutes, P < 0.001; %H2: 56.0 % vs. 81.5 %, P < 0.001; %H4: 15.0 % vs. 57.5 %, P = 0.003) at 3 months. The clinical success of G-POEM using the functional imaging probe inflated to 50 mL had specificity of 100 % and sensitivity of 72.2 % ( P = 0.04; 95 % confidence interval 0.51 - 0.94; area under the curve 0.72) at a distensibility threshold of 9.2 mm 2 /mmHg. G-POEM was efficacious and safe for treating refractory gastroparesis, especially in patients with low pyloric distensibility. © Georg Thieme Verlag KG Stuttgart · New York.
Endoscopic palliation of advanced esophageal cancer
Mocanu, A; Bârla, R; Hoara, P; Constantinoiu, S
2015-01-01
Esophageal cancer represents one of the most aggressive digestive tumors, with a survival rate at 5 years of only 10%. Globally, during the last three decades, there has been an increasing incidence of the esophageal cancer, approx. 400,000 new esophageal cancers being currently diagnosed annually. This represents the eighth leading cause of cancer incidence and the sixth leading cause of cancer death overall. Taking into account the population’s global aging and thus, the increase in the number of patients who will not bear surgery, PCT and radiation, or the fact that they do not want it especially because of deficiencies and associated pathology, the endoscopic ablative techniques with palliation purposes represent the alternative. If we refer to the Western Europe countries and North America, we notice an increase of esophageal adenocarcinoma rate versus squamous cancer. As for the Asian region, referring in particular to China and Japan, 9 out of 10 esophageal cancers are squamous cell carcinomas. For at least half of the patients with EC (esophageal cancer) there is no hope of healing because of the advanced regional malignant invasion (T3-4, N+, M+) with no chemo and radiotherapy response, poor preoperative patients’ conditions or systemic metastasis. The low life expectancy does not justify the risky medical procedures, the goal of the therapy consisting in the improvement of the quality of life by eliminating dysphagia (reestablishing oral feeding) which represents the most common complication of EC, the respiratory tract complication caused by eso-tracheal fistulas or by eliminating chest pain. To treat dysphagia, which is the main target of palliation, combined methods like endoscopic, chemo and radio-therapy, can be used, each one with indications, benefits and risks.

Current grading systems may not allow clinicians to reliably document and communicate adenotonsillar size in the clinical setting. A validated endoscopic grading system may be useful for reporting tonsillar size in future clinical outcome studies. This is especially important as tonsillar enlargement is the cause of a substantial health care burden on children. To propose and validate an easy-to-use flexible fiberoptic endoscopic grading system that provides physicians with a more accurate sense of the three-dimensional relationship of the tonsillar fossa to the upper-airway. 50 consecutive pediatric patients were prospectively recruited between February 2015 and February 2016 at a pediatric otolaryngology outpatient clinic. The patients had no major craniofacial abnormalities and were aged 1 to 16years. Each patient had data regarding BMI, Friedman palate position, OSA-18 survey results collected. For each child, digital video clips of fiberoptic nasopharyngeal, oropharyngeal and laryngeal exams were presented to 2 examiners. Examiners were asked to independently use the proposed Endoscopic tonsillar grading system, the Brodsky tonsillar grading scale, the Modified Brodsky tonsillar grading scale with a tongue depressor, and the Parikh adenoid grading system to rate adenotonsillar hypertrophy. Cohen's Kappa and weighted Kappa scores were used to assess interrater reliability for each of the four grading scales. The Spearman correlation was used to test the associations between each scale and OSA-18 scores, as well as Body Mass Index (BMI). 50 pediatric patients were included in this study (mean age 6.1years, range of 1year to 16years). The average BMI was 20. The average OSA-18 score was 61.7. The average Friedman palate position score was 1.34. Twelve percent of the patients had a Friedman palate position score≥3, which made traditional Brodsky grading of their tonsils impossible without a tongue depressor. All four scales showed strong agreement between the two raters. The weighted Kappa was 0.83 for the Modified Brodsky scale, 0.89 for the Brodsky scale, 0.94 for the Parikh scale to 0.98 for the Endoscopic scale (almost perfect agreement). The Endoscopic scale showed the most consistent agreement between the raters during the study. There was a moderate association between the Parikh adenoid grading system with OSA-18 scores (Spearman's ρ=0.58, p<0.001) compared to a low association of the tonsillar grading systems with OSA- 18 scores. None of the scales correlated with patient BMI. The proposed Endoscopic tonsillar grading system is as reliable of a method of grading tonsillar size as conventional grading systems. It offers the advantage of allowing for critical evaluation of the tonsils without any anatomic distortion which may occur with the use of a tongue blade. This new validated endoscopic grading system provides a tool for communicating the degree of airway obstruction at the level of the oropharynx regardless of Friedman palate position and may be used in future outcomes projects.

We studied 24-h rhythms of acid production and alkalization in 30 patients with duodenal ulcer (DU) and 30 healthy subjects using upper endoscopic examination and computer intragastric pH-metry. Gastric acid production was higher in DU patients and was more intensive in the daytime than at night. Healthy subjects had low and monotonous acid production. In DU decompensation of alkalization in the antral stomach and suppression of duodenogastric reflux is total. In healthy subjects antrum alkalization is more evident and intensive at night due to, among other causes, duodenogastric reflux.

A 72-year-old man with chronic alcohol related pancreatitis was admitted for dyspnea and pain at the upper body. Chest X-ray showed right massive pleural effusion. Chest and abdominal contrast enhanced thin slice computed tomography revealed the route from the pancreatic head reaching the right thoracic cavity via the esophagus hiatus and the communication between the cystic lesion and main pancreatic duct. We drained the pleural effusion that showed abnormally high amylase activity. We diagnosed his illness as mediastinal pancreatic pseudocyst with pancreatic pleural effusion. Endoscopic Nasopancreatic Drainage catheter was placed in the main pancreatic duct, and the pleural effusion disappeared.

We report a case of a 56-year-old woman with a history of allogenic bone marrow transplantation for two years, complaining with dysphagia and weight loss. Upper endoscopy revealed esophageal stenosis and extensive mucosa sloughing. Biopsies confirmed the diagnosis of graft-vs-host disease (GVHD). Balloon dilation, corticosteroids and cyclosporin resulted in marked clinical improvement. Gastrointestinal tract is involved in the majority of patients with chronic GVHD. Esophageal manifestations are rare and include vesiculobullous disease, ulceration, esophageal webs, casts or strictures. Sloughing esophagitis along with severe stenosis requiring endoscopic dilation has never been reported in this context.

To investigate the new surgical pathway of endoscopic frontal sinus surgery for frontal sinus lesions through the upper-agger nasi approach. The computed tomography (CT) scans from 32 patients were collected and subjected to three-dimensional reconstruction by Mimics. The distance in sagittal planes from anterior ethmoid artery to midpoint of axilla and to skull base attachment at anterior middle turbinate was measured. The distance in coronal planes between the perpendicular plate of middle turbinate and the orbital lamina was also detected as well as the height of agger nasi. Three-dimensional structures of the frontal sinus and its surrounding cells was reconstructed by Sinuses Trachea I software. We integrated the CT scans and the above data for simulating surgical operation on cadaveric heads. (1) Skull base attachment at anterior middle turbinate located at the anterior or posterior of aperture of frontal sinus. (2) The mean distance between anterior ethmoid artery and midpoint of axilla was (22.23 ± 2.78) mm on the left side and (22.30 ± 2.80) mm on right. The mean distance between anterior ethmoid artery and skull base attachment at anterior middle turbinate was (15.31 ± 2.82) mm on left and (15.39 ± 3.53) mm on right. The distance between perpendicular plate of middle turbinate and orbital lamina was (7.61 ± 1.34) mm on left and (7.80 ± 1.40) mm on right side. The height of the agger nasi was (8.33 ± 2.14) mm on left and (8.00 ± 2.57) mm on right. There was no statistical difference in the above data between left and right side (P > 0.05). (3) The visible three-dimensional structure showed that skull base attachment at the anterior middle turbinate was closely adjoined the aperture of frontal sinus, the space between sub-outer side of the attachment and orbital lamina, above the agger nasi cell or the upper area of the agger nasi cell was solely cell structures. Endoscopic frontal sinus surgery for frontal sinus lesions through the upper-agger nasi approach was practicable to solitary frontal sinus lesions and to solve the complex frontal sinus or frontal recess lesions by flexible operation according to the feature of the lesions.

Recent non-randomized studies suggest that extended endoscopic mucosal resection (EMR) is equally effective in removing large rectal adenomas as transanal endoscopic microsurgery (TEM). If equally effective, EMR might be a more cost-effective approach as this strategy does not require expensive equipment, general anesthesia and hospital admission. Furthermore, EMR appears to be associated with fewer complications.The aim of this study is to compare the cost-effectiveness and cost-utility of TEM and EMR for the resection of large rectal adenomas. Multicenter randomized trial among 15 hospitals in the Netherlands. Patients with a rectal adenoma > or = 3 cm, located between 1-15 cm ab ano, will be randomized to a TEM- or EMR-treatment strategy. For TEM, patients will be treated under general anesthesia, adenomas will be dissected en-bloc by a full-thickness excision, and patients will be admitted to the hospital. For EMR, no or conscious sedation is used, lesions will be resected through the submucosal plane in a piecemeal fashion, and patients will be discharged from the hospital. Residual adenoma that is visible during the first surveillance endoscopy at 3 months will be removed endoscopically in both treatment strategies and is considered as part of the primary treatment. Primary outcome measure is the proportion of patients with recurrence after 3 months. Secondary outcome measures are: 2) number of days not spent in hospital from initial treatment until 2 years afterwards; 3) major and minor morbidity; 4) disease specific and general quality of life; 5) anorectal function; 6) health care utilization and costs. A cost-effectiveness and cost-utility analysis of EMR against TEM for large rectal adenomas will be performed from a societal perspective with respectively the costs per recurrence free patient and the cost per quality adjusted life year as outcome measures. Based on comparable recurrence rates for TEM and EMR of 3.3% and considering an upper-limit of 10% for EMR to be non-inferior (beta-error 0.2 and one-sided alpha-error 0.05), 89 patients are needed per group. The TREND study is the first randomized trial evaluating whether TEM or EMR is more cost-effective for the treatment of large rectal adenomas. (trialregister.nl) NTR1422.

Background Recent non-randomized studies suggest that extended endoscopic mucosal resection (EMR) is equally effective in removing large rectal adenomas as transanal endoscopic microsurgery (TEM). If equally effective, EMR might be a more cost-effective approach as this strategy does not require expensive equipment, general anesthesia and hospital admission. Furthermore, EMR appears to be associated with fewer complications. The aim of this study is to compare the cost-effectiveness and cost-utility of TEM and EMR for the resection of large rectal adenomas. Methods/design Multicenter randomized trial among 15 hospitals in the Netherlands. Patients with a rectal adenoma ≥ 3 cm, located between 1–15 cm ab ano, will be randomized to a TEM- or EMR-treatment strategy. For TEM, patients will be treated under general anesthesia, adenomas will be dissected en-bloc by a full-thickness excision, and patients will be admitted to the hospital. For EMR, no or conscious sedation is used, lesions will be resected through the submucosal plane in a piecemeal fashion, and patients will be discharged from the hospital. Residual adenoma that is visible during the first surveillance endoscopy at 3 months will be removed endoscopically in both treatment strategies and is considered as part of the primary treatment. Primary outcome measure is the proportion of patients with recurrence after 3 months. Secondary outcome measures are: 2) number of days not spent in hospital from initial treatment until 2 years afterwards; 3) major and minor morbidity; 4) disease specific and general quality of life; 5) anorectal function; 6) health care utilization and costs. A cost-effectiveness and cost-utility analysis of EMR against TEM for large rectal adenomas will be performed from a societal perspective with respectively the costs per recurrence free patient and the cost per quality adjusted life year as outcome measures. Based on comparable recurrence rates for TEM and EMR of 3.3% and considering an upper-limit of 10% for EMR to be non-inferior (beta-error 0.2 and one-sided alpha-error 0.05), 89 patients are needed per group. Discussion The TREND study is the first randomized trial evaluating whether TEM or EMR is more cost-effective for the treatment of large rectal adenomas.

Upper gastrointestinal bleeding is a major cause of hospitalization and the most prevalent emergency worldwide, with a mortality rate of up to 14%. In Peru, there have not been any studies on the use of the Glasgow-Blatchford Scoring System to predict mortality in upper gastrointestinal bleeding. The aim of this study is to perform an external validation of the Glasgow-Blatchford Scoring System and to establish the best cutoff for predicting mortality in upper gastrointestinal bleeding in a hospital of Lima, Peru. This was a longitudinal, retrospective, analytical validation study, with data from patients with a clinical and endoscopic diagnosis of upper gastrointestinal bleeding treated at the Gastrointestinal Hemorrhage Unit of the Hospital Nacional Edgardo Rebagliati Martins between June 2012 and December 2013. We calculated the area under the curve for the receiver operating characteristic of the Glasgow-Blatchford Scoring System to predict mortality with a 95% confidence interval. A total of 339 records were analyzed. 57.5% were male and the mean age (standard deviation) was 67.0 (15.7) years. The median of the Glasgow-Blatchford Scoring System obtained in the population was 12. The ROC analysis for death gave an area under the curve of 0.59 (95% CI 0.5-0.7). Stratifying by type of upper gastrointestinal bleeding resulted in an area under the curve of 0.66 (95% CI 0.53-0.78) for non-variceal type. In this population, the Glasgow-Blatchford Scoring System has no diagnostic validity for predicting mortality.

Upper GI endoscopy has an important diagnostic and therapeutic role in the management of nonvariceal upper GI bleeding (NVUGB). To characterize nationwide patterns of utilization of upper GI endoscopy in pregnant women with NVUGB and to assess health outcomes. Retrospective cohort study. Participating hospitals from the Nationwide Inpatient Sample, 1998-2007. Pregnant and age-matched nonpregnant women admitted for NVUGB. The study population was classified as pregnant women with NVUGB (n = 1210) and nonpregnant women with NVUGB (n = 6050). Rate of upper GI endoscopy, maternal mortality, fetal death/complications, and premature delivery. Pregnant women were less likely than nonpregnant women to undergo upper GI endoscopy (26% vs 69%; P < .0001) even after adjustment for comorbidities, transfusion requirement, and the presence of hypovolemic shock (adjusted odds ratio, 0.19; 95% confidence interval, 0.16-0.22). Among those who underwent endoscopy, pregnant women were less likely to undergo the procedure within 24 hours of admission (50% vs 57%; P = .02). Mortality was lower among pregnant women compared with nonpregnant women (0% vs 0.6%; P = .006). In comparing outcomes between those who did and did not undergo endoscopy, there was no difference in fetal loss (0.2% vs 0.6%), fetal distress/complications (2.7% vs 2.6%), or premature delivery (7.3% vs 6.4%). The study was based on administrative data. A conservative nonendoscopic approach is common in the management of pregnant women with NVUGB and is not associated with worse maternal or fetal outcomes. Upper GI endoscopy is, however, safe when judiciously implemented in the actively bleeding patient. Copyright © 2010 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc.

We have recognized a unique clinical syndrome in patients with upper gastrointestinal bleeding who are found to have severe esophagitis. We aimed to more clearly describe the clinical entity of upper gastrointestinal bleeding in patients with severe esophagitis. We conducted a retrospective matched case-control study designed to investigate clinical features in patients with carefully defined upper gastrointestinal bleeding and severe esophagitis. Patient data were captured prospectively via a Gastrointestinal Bleeding Healthcare Registry, which collects data on all patients admitted with gastrointestinal bleeding. Patients with endoscopically documented esophagitis (cases) were matched with randomly selected controls that had upper gastrointestinal bleeding caused by other lesions. Epidemiologic features in patients with esophagitis were similar to those with other causes of upper gastrointestinal bleeding. However, hematemesis was more common in patients with esophagitis 86% (102/119) than in controls 55% (196/357) (p < 0.0001), while melena was less common in patients with esophagitis 38% (45/119) than in controls 68% (244/357) (p < 0.0001). Additionally, the more severe the esophagitis, the more frequent was melena. Patients with esophagitis had less abnormal vital signs, lesser decreases in hematocrit, and lesser increases in BUN. Both pre- and postRockall scores were lower in patients with esophagitis compared with controls (p = 0.01, and p < 0.0001, respectively). Length of hospital stay (p = 0.002), rebleeding rate at 42 days (p = 0.0007), and mortality were less in patients with esophagitis than controls. Finally, analysis of patients with esophagitis and cirrhosis suggested that this group of patients had more severe bleeding than those without cirrhosis. We have described a unique clinical syndrome in patients with upper gastrointestinal bleeding who have erosive esophagitis. This syndrome is manifest by typical clinical features and is associated with favorable outcomes.

Esophageal candidiasis mostly occurs in the immunocompromised host. However, it may also affect healthy people and is frequently asymptomatic. The clinical significance of asymptomatic esophageal candidiasis (AEC) is still unclear. The aims of the study were to investigate the prevalence of AEC during health inspection and to identify its predisposing factors and clinical significance. A total of 49,497 subjects who underwent a health inspection that included upper endoscopy were enrolled. We retrospectively reviewed the subject's self-reporting questionnaires, medical records and endoscopic findings. We considered "long-term" follow-up to be >6 months with at least one more follow-up endoscopy. One hundred and seventy (0.4%) subjects were endoscopically diagnosed as esophageal candidiasis and 141 subjects were AEC. Multivariate analysis revealed that old age (≥60 years) was an independent risk factor for AEC (OR, 1.862, p = 0.005). The number of subjects with long-term follow-up was 79 (195.3 person-years). Among these, AEC of 64 subjects (81.0%) had disappeared on the follow-up endoscopy and was not recurrent. The other 15 subjects had AEC diagnosed more than once on the follow-up endoscopy, and 5 of them were spontaneously healed during the follow-up period. The remaining 10 subjects whose candidiasis was sustained up to the last endoscopy did not complain of symptoms during the follow-up period, and their endoscopic findings did not worsen. AEC is rare and old age is the only risk factor. AEC does not require medical care because it is a self-limited disease.

Helicobacter pylori (Hp) infection is a common and universally distributed bacterial infection. It is predominantly acquired in childhood. To assess the relationship between endoscopic nodular gastritis and Hp infection. A retrospective study was conducted in children who underwent upper gastrointestinal endoscopy for chronic abdominal pain. All children who had five gastric biopsies for histologic analysis, urease test and Hp culture were included in the study. The Sensitivity and sensibility of nodular gastritis were determined and different parameters were studied according the presence or not of nodular gastritis(age, gender, Hp status, gastritis score and lymphoid follicles). 49 children, mean age 6.9 ± 3 years (range 1-12 years) were eligible for the analysis. Hp Infection was diagnosed in 35 out of the 49 children (71.5 %). Nodular gastritis was recorded in 16 out of 49 children and in 14 infected children and 2 out of 14 non infected children (p=0.07), 40% sensitivity, 85.7% specificity, 87.5% positive predictive value, and 36,4% negative predictive value. The parameters associated significantly to the presence of nodular gastritis were older age: (p=0.04), Hp infection: (p=0.01), chronic gastritis: (p=0.05), active gastritis: (p=0.02), follicular gastritis: (p=0.005), higher gastritis score: (p=0.005). Completely normal gastric mucosal histology was never found in infected children with antral nodularity. Among all infected children, the gastritis score was significantly higher when there was a nodular gastritis and follicular gastritis was significantly associated to nodular gastritis. The endoscopic pattern of antral nodularity identifies children with Hp infection, and active chronic follicular gastritis.

We previously reported a modified endoscopic medial maxillectomy (modified transnasal endoscopic medial maxillectomy through prelacrimal duct approach [MTEMMPDA]) to resect inverted papilloma (IP), for which the inferior turbinate (IT) and nasolacrimal duct (ND) can be preserved. MTEMMPDA is a safe and effective method to obtain wide, straight access to the maxillary sinus (MS). However, there are few reported cases of patients who underwent MTEMMPDA, and even fewer of patients who underwent partial osteotomy of the apertura piriformis and the anterior wall of the MS. In this study, we analyzed the outcomes of 51 patients who underwent MTEMMPDA. Retrospective review. All patients who underwent MTEMMPDA at our hospital between January 2004 and December 2015 were included in this study. Fifty-one patients with sinonasal IP in the MS underwent MTEMMPDA. Recurrence was seen in the MS of one patient (follow-up of 2-138 months). The IT remained unchanged in all 51 patients without atrophy. We have not observed epiphora, eye discharge, dry nose, or persistent crusting after this surgery. Although seven patients had numbness around the upper lip after surgery, this had disappeared by 1 year after surgery. Additional partial osteotomy of the apertura piriformis and the anterior wall of the MS were done in eight patients. Deformation of the external nose was not seen. This approach appears to be a safe and effective method to resect IP in the MS, even if there is additional partial osteotomy of the apertura piriformis and the anterior wall of the MS. 4.

The impact of new technology on surgery for colorectal cancer
Makin, Gregory B; Breen, David J; Monson, John RT
2001-01-01
Advances in technology continue at a rapid pace and affect all aspects of life, including surgery. We have reviewed some of these advances and the impact they are having on the investigation and management of colorectal cancer. Modern endoscopes, with magnifying, variable stiffness and localisation capabilities are making the primary investigation of colonic cancer easier and more acceptable for patients. Imaging investigations looking at primary, metastatic and recurrent disease are shifting to digital data sets, which can be stored, reviewed remotely, potentially fused with other modalities and reconstructed as 3 dimensional (3D) images for the purposes of advanced diagnostic interpretation and computer assisted surgery. They include virtual colonoscopy, trans-rectal ultrasound, magnetic resonance imaging, positron emission tomography and radioimmunoscintigraphy. Once a colorectal carcinoma is diagnosed, the treatment options available are expanding. Colonic stents are being used to relieve large bowel obstruction, either as a palliative measure or to improve the patient’s overall condition before definitive surgery. Transanal endoscopic microsurgery and minimally invasive techniques are being used with similar outcomes and a lower mortality, morbidity and hospital stay than open trans-abdominal surgery. Transanal endoscopic microsurgery allows precise excision of both benign and early malignant lesions in the mid and upper rectum. Survival of patients with inoperable hepatic metastases following radiofrequency ablation is encouraging. Robotics and telemedicine are taking surgery well into the 21st century. Artificial neural networks are being developed to enable us to predict the outcome for individual patients. New technology has a major impact on the way we practice surgery for colorectal cancer.

The use of the retrosigmoid approach has recently been expanded by several modifications, including the suprameatal, transmeatal, suprajugular, and inframeatal extensions. Intradural temporal bone drilling without damaging vital structures inside or beside the bone, such as the internal carotid artery and jugular bulb, is a key step for these extensions. This study aimed to examine the microsurgical and endoscopic anatomy of the extensions of the retrosigmoid approach and to evaluate the clinical feasibility of an electromagnetic navigation system during intradural temporal bone drilling. Five temporal bones and 8 cadaveric cerebellopontine angles were examined to clarify the anatomy of retrosigmoid intradural temporal bone drilling. Twenty additional cerebellopontine angles were dissected in a clinical setting with an electromagnetic navigation system while measuring the target registration errors at 8 surgical landmarks on and inside the temporal bone. Retrosigmoid intradural temporal bone drilling expanded the surgical exposure to allow access to the petroclival and parasellar regions (suprameatal), internal acoustic meatus (transmeatal), upper jugular foramen (suprajugular), and petrous apex (inframeatal). The electromagnetic navigation continuously guided the drilling without line of sight limitation, and its small devices were easily manipulated in the deep and narrow surgical field in the posterior fossa. Mean target registration error was less than 0.50 mm during these procedures. The combination of endoscopic and microsurgical techniques aids in achieving optimal exposure for retrosigmoid intradural temporal bone drilling. The electromagnetic navigation system had clear advantages with acceptable accuracy including the usability of small devices without line of sight limitation. Copyright © 2017 Elsevier Inc.

Surgery of the craniocervical junction (CCJ) and clivus is technically demanding. For many years, we have used the submandibular retropharyngeal approach for surgery of the upper cervical spine, especially hangman fracture. We hypothesized that submandibular gland resection could offer a significant cranial enlargement of the operative field, up to the clivus. Our aim in this work was to assess the feasibility of an endoscope-assisted retropharyngeal approach to the CCJ and clivus. Eight anatomic specimens were used, including 4 silicon-injected specimens. We performed a submandibular retropharyngeal approach with gland resection, and then we exposed the CCJ and clivus. We drilled the C2 vertebral body, odontoid process, C1 anterior arch, and the clivus. We noted 8 anatomic landmarks that were easily identified on each anatomic specimen. These measurements were designed to quantify the exposure of the clivus and CCJ after bone resection. A submandibular approach was feasible in all specimens. The main dimensions of the area of dural exposure after bone drilling were as follows: mean width between C1 lateral masses, 19 mm (range, 17-20 mm); at the tip of the clival window, 18 mm (range, 16-20 mm); distance between the C3 vertebra and the tip of the window within the clivus, 57 mm (range, 55-60 mm). An endoscopic submandibular retropharyngeal approach provides a simple and straightforward access to the CCJ. It also conveniently exposes the clivus. This technique could be added to the techniques used for this difficult surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

OBJECTIVES--To ascertain the proportion of endoscopic examinations with normal findings in patients referred for gastroscopy through hospital medical staff or directly by their general practitioner and to assess the likely effect of targeting endoscopy in older patients. DESIGN--Retrospective audit of the gastroscopy practice of one consultant from 1986 to 1988 from information recorded on a standard form completed at the time of the examination, which contained details of patients, their endoscopic findings, and mode of referral (open access or clinic). SETTING--One district general hospital. PATIENTS--1545 Consecutive patients from primary catchment area attending for their first gastroscopy; 454 were referred through the outpatient clinic or by hospital colleagues (clinic group) and 1091 were accepted for endoscopy solely on their general practitioner's clinical diagnosis (open access group). RESULTS--Similar numbers (about 40%) of examinations with normal findings were performed in each group, although in patients aged over 40 the proportion with normal findings was significantly higher in the clinic group (p less than 0.03). Endoscopic evidence of gastro-oesophageal reflux disease, peptic ulceration, and gastroduodenal inflammation was equally common in each group; upper gastrointestinal malignancy, however, was significantly more common in patients referred through hospital doctors (5%, 23/454 v 2%, 22/1091 respectively; p less than 0.005) (although many of these patients had already been extensively investigated). IMPLICATIONS--Open access gastroscopy does not increase the number of unnecessary examinations and should become more widely available. Targeting this service to patients aged over 40 would reduce the number of requests but increase the diagnostic yield. PMID:2106992

To retrospectively evaluate the incidence, predictive factors, and interventional management of food impaction after expandable metallic stent placement in patients with obstruction of the esophagus or upper gastrointestinal tract caused by benign or malignant disease. Between March 1993 and March 2010, 1,360 patients (1,029 men, 331 women; age range, 21-89 y; mean age, 61 y) underwent fluoroscopically guided stent placement for dysphagia caused by esophageal or gastrointestinal tract strictures. Five types of covered expandable metal stents were used, including four types of esophageal stents (types A-D) and one type of gastroduodenal stent (type E), with types A, B, C, D, and E stents used in 180, 60, 90, 432, and 598 patients, respectively. Multivariate analysis was performed to evaluate factors predictive of food impaction. Food impaction occurred in 41 of 1,360 patients (3.0%). The food impaction rates for types A, B, C, D, and E stents were 0.6%, 1.7%, 1.1%, 3.2%, and 4.0%, respectively. Multivariate analysis showed that stent length was an independent predictor of food impaction (odds ratio, 0.839; P = .012). Of the 41 patients with food impaction, 23 underwent endoscopic management, 12 underwent fluoroscopically guided management, and six did not require management because impacted food spontaneously passed through the stent. The overall food impaction rate was 3.0%, with multiple logistic regression analysis showing that shorter stent length was the only significant predictor of food impaction. Food impaction can be managed by endoscopic or fluoroscopically guided removal or placement of a second stent. Copyright © 2011 SIR. Published by Elsevier Inc. All rights reserved.

Current video-assisted thoracoscopic surgery training models rely on animals or mannequins to teach procedural skills. These approaches lack inherent teaching/testing capability and are limited by cost, anatomic variations, and single use. In response, we hypothesized that video-assisted thoracoscopic surgery right upper lobe resection could be simulated in a virtual reality environment with commercial software. An anatomy explorer (Maya [Autodesk Inc, San Rafael, Calif] models of the chest and hilar structures) and simulation engine were adapted. Design goals included freedom of port placement, incorporation of well-known anatomic variants, teaching and testing modes, haptic feedback for the dissection, ability to perform the anatomic divisions, and a portable platform. Preexisting commercial models did not provide sufficient surgical detail, and extensive modeling modifications were required. Video-assisted thoracoscopic surgery right upper lobe resection simulation is initiated with a random vein and artery variation. The trainee proceeds in a teaching or testing mode. A knowledge database currently includes 13 anatomic identifications and 20 high-yield lung cancer learning points. The "patient" is presented in the left lateral decubitus position. After initial camera port placement, the endoscopic view is displayed and the thoracoscope is manipulated via the haptic device. The thoracoscope port can be relocated; additional ports are placed using an external "operating room" view. Unrestricted endoscopic exploration of the thorax is allowed. An endo-dissector tool allows for hilar dissection, and a virtual stapling device divides structures. The trainee's performance is reported. A virtual reality cognitive task simulation can overcome the deficiencies of existing training models. Performance scoring is being validated as we assess this simulator for cognitive and technical surgical education. Copyright © 2011. Published by Mosby, Inc.

Low-dose aspirin is known to cause upper gastrointestinal complications. The mechanism by which the aspirin disrupts gastric mucosal integrity remains to be clarified. In this study we investigated the temporal association of gastric secretory parameters (acid and mucus) with aspirin-induced gastropathy. In 42 long-term low-dose aspirin-takers and the same number of sex- and age-matched controls, pentagastrin-stimulated gastric juice was collected for 10 min during endoscopic examination. The collected gastric juice was divided and half was submitted to analysis for gastric acid (mEq/10 min) and the other half was analyzed for mucin (mg hexose/10 min) output. The grade of gastric mucosal injury was assessed endoscopically according to the modified Lanza score, and a score of more than 4 was defined as the presence of severe gastropathy. While gastric acid secretion did not differ significantly between aspirin-takers and controls, gastric mucus secretion, in terms of mucin output, was significantly increased in aspirin-takers compared to controls (4.1 (SD 4.8) vs. 2.3 (1.4) mg hexose/10 min, P < 0.05). Consequently, the acid/mucin ratio was significantly decreased in aspirin-takers compared to controls (1.2 (1.0) vs. 1.7 (1.4), P < 0.05). In the subanalysis of 25 aspirin-takers without severe gastropathy, gastric mucus secretion was increased and the acid/mucus ratio was decreased compared with controls, but there was no such association in the remaining 17 aspirin-takers with severe gastropathy. Overall, gastric mucus secretion is increased in aspirin-takers, suggesting a functional adaptive response to long-term administration of the drug. However, it is possible that the adaptive response is impaired in some aspirin takers, who might be susceptible to severe upper gastrointestinal complication.

Some gastric cancers are Epstein-Barr virus associated. To assess the prevalence of Helicobacter pylori and viral co-infection in benign upper digestive diseases. One hundred and four outpatients were included in a prospective endoscopic-serologic study. Epstein-Barr virus immunoglobulin G (IgG), immunoglobulin M and viral capsid antigen titres were assayed with an ELISA test. Helicobacter pylori was determined by the modified Giemsa stain and by IgG-chemiluminescence. The overall prevalence of Helicobacter pylori was 56.7%. Duodenal ulcer patients were infected in 72.5 % of the cases, with the prevalence being 33.3% in functional dyspepsia (p = 0.0008) and 25.8% in reflux patients (p = 0.0001). Epstein-Barr virus IgG was detected in 70.1% of the whole group, 75% of duodenal ulcer patients, 51.2% of functional dyspepsia patients (p = 0.04) and 51.6% of the reflux disease cases (p = 0.04). Co-infection with both agents was detected in 60% of duodenal ulcer patients, 18.1% of functional dyspepsia (p = 0.00014) and 12.9% of reflux disease patients (p = 0.00012). Anti-viral IgG titre displayed a 31.7 ± 3.0 cut-off index in duodenal ulcer, 20.5 ± 3.5 in functional dyspepsia (p = 0.01) and 21.4 ± 3.6 in reflux cases (p = 0.03). Both Helicobacter pylori and Epstein-Barr virus, and co-infection with these agents, were significantly more prevalent in duodenal ulcer patients than in dyspeptic/reflux patients.

Background and study aims Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome caused by a germline mutation in the adenomatous polyposis coli (APC) gene, characterized by the presence of more than 100 adenomatous polyps in the colorectum. The upper gastrointestinal tract is an extracolonic site for malignancy in patients with FAP. The frequency of death in Japanese patients with FAP because of gastric cancer is 2.8 % and that because of colon cancer is 60.6 %. Few studies have reported upper gastrointestinal diseases in patients with FAP. In the present study, we investigated the clinical outcomes of patients with FAP diagnosed with gastric neoplasms. Patients and methods We enrolled 80 patients with FAP who underwent esophagogastroduodenoscopy from October 1997 to December 2011. We investigated patient characteristics, endoscopic findings of gastric lesions, treatment outcomes, and long-term courses. Results Fundic gland polyposis was observed in 51 patients (64 %) and gastric neoplasms in 22 patients (28 %), including 20 with non-invasive and 2 with invasive neoplasm. Of the 26 neoplasms, 11 were treated by endoscopic resection (ER) and 4 by surgical resection. Metachronous gastric neoplasms were observed in 7 patients (15 lesions) and treated by ER, except for in 1 patient. No patients died of gastric lesions during a median follow-up period of 6.5 years (range, 0 – 14). Conclusion Because gastric lesions including gastric cancers in patients with FAP did not cause any deaths, they can be considered to have favorable prognoses. Early detection of gastric neoplasms through an appropriate follow-up interval may have contributed to these good outcomes. PMID:28271094

Background and Objectives: Failures of endoscopic ultrasound (EUS) imaging of the head of the pancreas (HOP) and the common bile duct (CBD) have been reported in up to 50% of patients with status postsurgery (e.g., Billroth II and Roux-en-Y). This is attributable to inability to intubate the afferent limb or the duodenum. Recently, a forward-view (FV) echoendoscope has become available. The frontal endoscopic and ultrasound field of view theoretically allow easier manipulation throughout the gastrointestinal tract compared to the traditional echoendoscopes. The aim of our study was to evaluate the safety and performance of the FV echoendoscope for the investigation of the biliary tree and the pancreas, including fine-needle aspiration (FNA), in patients with surgically altered upper gastrointestinal anatomy. Patients and Methods: This was a retrospective evaluation of a prospectively maintained database. All EUS procedures were performed at our institution by one experienced endosonographer from March to September 2009 under conscious sedation. The FV echoendoscope was used for all procedures. Results: Twenty-five (25) out of 37 presented status post-Billroth II and 12 out of 37 with status post-Roux-en-Y surgery. Overall, HOP and CBD were adequately visualized in 28 out of 37 (75.7%). All the failures occurred in the Roux-en-Y patients. EUS-FNA was successfully performed in 16 patients. No adverse events were observed. Conclusions: The FV echoendoscope proved to be safe and effective in reaching the periampullary area in patients with previous Billroth II, allowing complete exploration of the HOP and the CBD and performance of EUS-FNA. However, FV EUS was unsuccessful in the majority of patients with Roux-en-Y, which still remains a challenging condition. PMID:26643703

Upper gastrointestinal bleeding (UGIB) is a common emergency, with in-hospital mortality between 3 and 14%. However, the long-term mortality and causes of death are unknown. We investigated the long-term mortality and causes of death in UGIB patients in a retrospective single-centre case-control study design. A total of 569 consecutive patients, aged ≥18 years, admitted to Kuopio University Hospital for their first endoscopically verified UGIB during the years 2009-2011 were identified from hospital records. For each UGIB patient, an age, sex and hospital district matched control patient was identified from the Statistics Finland database. Data on endoscopy procedures, laboratory values, comorbidities and medication were obtained from patient records. Data on deaths and causes of death were obtained from Statistics Finland. In-hospital mortality of UGIB patients was low at 3.3%. The long-term (mean follow-up 32 months) mortality of UGIB patients was significantly higher than controls (34.1 versus 12.1%, p < .001). During the 6 months following UGIB, the risk of death compared to controls was highest (HR 19.2, 95% CI 7.0-52.4, p < .001) and remained higher up to 3 years after the bleeding. Beyond 3 years' follow-up, there was no difference in mortality between the groups (HR 0.7, 95% CI 0.4-1.6, p = .436). During the first 3 months after the UGIB episode, mortality was related to gastrointestinal diseases; after 3 months, the causes of death were related to comorbidities and did not differ from causes of death in controls. UGIB patients have three times higher long-term mortality than population controls.

Several treatments have been proven to be effective for variceal bleeding in patients with cirrhosis. The aim of this multicenter, prospective, cohort study was to assess how these treatments are used in clinical practice and what are the posttherapeutic prognosis and prognostic indicators of upper digestive bleeding in patients with cirrhosis. A training set of 291 and a test set of 174 bleeding cirrhotic patients were included. Treatment was according to the preferences of each center and the follow-up period was 6 weeks. Predictive rules for 5-day failure (uncontrolled bleeding, rebleeding, or death) and 6-week mortality were developed by the logistic model in the training set and validated in the test set. Initial treatment controlled bleeding in 90% of patients, including vasoactive drugs in 27%, endoscopic therapy in 10%, combined (endoscopic and vasoactive) in 45%, balloon tamponade alone in 1%, and none in 17%. The 5-day failure rate was 13%, 6-week rebleeding was 17%, and mortality was 20%. Corresponding findings for variceal versus nonvariceal bleeding were 15% versus 7% (P =.034), 19% versus 10% (P =.019), and 20% versus 15% (P =.22). Active bleeding on endoscopy, hematocrit levels, aminotransferase levels, Child-Pugh class, and portal vein thrombosis were significant predictors of 5-day failure; alcohol-induced etiology, bilirubin, albumin, encephalopathy, and hepatocarcinoma were predictors of 6-week mortality. Prognostic reassessment including blood transfusions improved the predictive accuracy. All the developed prognostic models were superior to the Child-Pugh score. In conclusion, prognosis of digestive bleeding in cirrhosis has much improved over the past 2 decades. Initial treatment stops bleeding in 90% of patients. Accurate predictive rules are provided for early recognition of high-risk patients.

Eosinophilic esophagitis (EoE) is being recognized increasingly all over the globe; Indian data is however sparse. We screened patients with symptoms of gastroesophageal reflux disease (GERD) for presence of EoE in them. Consecutive patients with symptoms suggestive of GERD underwent gastroduodenoscopy and esophageal biopsies, obtained from both the upper esophagus (5 cm below the upper esophageal sphincter) and lower esophagus (5 cm above gastroesophageal junction), as well as from any other endoscopically visible abnormal mucosa. Demographic and clinical characteristics, endoscopic findings, peripheral blood eosinophilic count, and history of use of proton-pump inhibitors (PPIs) were analyzed. Stool examination was done to rule out parasitoids. EoE was diagnosed if number of mucosal eosinophil infiltrate was >20 per high-power field. In the latter, Warthin-Starry stain was performed to rule out presence of H elicobacter pylori. Of 190 consecutive patients with symptoms of GERD screened, esophageal biopsies were available in 185 cases. Of them, 6 had EoE, suggesting a prevalence of 3.2% among patients with GERD. On univariate analysis, history of allergy, non-response to PPI, and absolute eosinophil counts and on multivariable analysis, history of allergy and no response to PPIs were significant predictors of EoE. Presence of EOE did not correlate with severity of reflux symptoms. In this hospital-based study from northern part of India, prevalence of EoE in patients with GERD was 3.2%. EoE should be considered as a diagnostic possibility, especially in those with history of allergy, no-response to PPI, and absolute eosinophil count of ≥250/cumm.

To evaluate the safety and efficacy of a modified cyanoacrylate [N-butyl-2-cyanoacrylate associated with methacryloxysulfolane (NBCA + MS)] to treat non-variceal upper gastrointestinal bleeding (NV-UGIB). In our retrospective study we took into account 579 out of 1177 patients receiving endoscopic treatment for NV-UGIB admitted to our institution from 2008 to 2015; the remaining 598 patients were treated with other treatments. Initial hemostasis was not achieved in 45 of 579 patients; early rebleeding occurred in 12 of 579 patients. Thirty-three patients were treated with modified cyanoacrylate: 27 patients had duodenal, gastric or anastomotic ulcers, 3 had post-mucosectomy bleeding, 2 had Dieulafoy's lesions, and 1 had duodenal diverticular bleeding. Of the 45 patients treated endoscopically without initial hemostasis or with early rebleeding, 33 (76.7%) were treated with modified cyanoacrylate glue, 16 (37.2%) underwent surgery, and 3 (7.0%) were treated with selective transarterial embolization. The mean age of patients treated with NBCA + MS (23 males and 10 females) was 74.5 years. Modified cyanoacrylate was used in 24 patients during the first endoscopy and in 9 patients experiencing rebleeding. Overall, hemostasis was achieved in 26 of 33 patients (78.8%): 19 out of 24 (79.2%) during the first endoscopy and in 7 out of 9 (77.8%) among early rebleeders. Two patients (22.2%) not responding to cyanoacrylate treatment were treated with surgery or transarterial embolization. One patient had early rebleeding after treatment with cyanoacrylate. No late rebleeding during the follow-up or complications related to the glue injection were recorded. Modified cyanoacrylate solved definitively NV-UGIB after failure of conventional treatment. Some reported life-threatening adverse events with other formulations, advise to use it as last option.

Upper gastrointestinal bleeding (UGIB) is a threatening condition leading to urgent hospitalization. This study aims to investigate etiology and outcome in UGIB patients in Iran. Medical records of GIB patients admitted to Alzahra referral hospital (in Isfahan) during 2010-2015 were retrospectively reviewed for demographic data, comorbidities, history of smoking and taking non-steroidal anti-inflammatory drugs (NSAIDs), presenting symptoms, endoscopic findings, therapeutic endoscopy, blood products' infusion, surgical intervention, rebleeding, and mortality. A total of 4747 patients were enrolled in the study (69.2% men, mean age = 55.46 ± 21.98 years). Hematemesis was the most frequent presenting symptom (63.5%). Peptic ulcer (duodenal ulcer in most cases) was seen as the main reason for UGIB (42.4%). Rebleeding (present in 16.5% of patients) was found to be more frequent in patients with older age, presenting sign of hematochezia and hypotension, history of taking NSAIDs and smoking, presence of comorbidities, history of bleeding because of UGI tract neoplasm and esophageal varices, history of needing blood products' infusion, and history of therapeutic endoscopy or surgical intervention (P < 0.005). We found that mortality (5.5% in total) was also higher in the same group of patients that were seen to have a higher tendency for rebleeding (P < 0.005). Peptic ulcers are the most common cause of UGIB. Comorbidities, hemodynamic instability, high-risk endoscopic stigmata, history of smoking and taking NSAIDs, gastric and esophageal malignancies, may be important predisposing factors for rebleeding and mortality in patients with UGIB. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Previous studies support good intra- and interobserver agreements for endoscopic evaluation of various upper respiratory tract (URT) diseases in horses. However, these studies mainly assessed resting endoscopic examination videos and/or focussed on a single URT abnormality. To estimate intra- and interobserver agreement for identification and grading of all URT abnormalities from resting and overground endoscopy (OGE) videos of Thoroughbreds. Blinded, fully crossed design. Resting and OGE URT videos for n = 43 Thoroughbreds were retrospectively chosen based on identification of common URT disorders. The videos were randomly evaluated in duplicate by 4 raters blinded to all information including prior URT disorder(s) diagnosis. Abnormalities were graded using well-described ordinal scales. Intra- and interobserver agreements were estimated using Cohen's weighted κ and Krippendorff's α, respectively. Intraobserver agreement was perfect/nearly perfect for arytenoid symmetry at exercise, epiglottic entrapment and epiglottic retroversion, substantial for arytenoid asymmetry at rest, palatal dysfunction (PD), medial deviation of the aryepiglottic folds (MDAF), pharyngeal mucus and epiglottic grade at exercise and moderate for vocal fold collapse (VFC), ventromedial luxation of the apex of the corniculate process of the arytenoid (VLAC), nasopharyngeal collapse (NPC) and epiglottic grade at rest. Interobserver agreement was substantial for arytenoid symmetry at exercise and PD and moderate for arytenoid asymmetry at rest, MDAF, VLAC and epiglottic entrapment. It was only fair for VFC, epiglottic grade at exercise, epiglottic retroversion, pharyngeal mucus and NPC and poor for epiglottic grade at rest. Sample size was insufficient to allow assessment of the effect of one abnormality on the grading of another abnormality. Observers were consistent in grading URT disorders. However, significant disparity in grading existed between observers for some conditions affecting reliability. © 2016 EVJ Ltd.

Bronchoscopic thermal vapor ablation (BTVA) represents one of the endoscopic lung volume reduction (ELVR) techniques that aims at hyperinflation reduction in patients with advanced emphysema to improve respiratory mechanics. By targeted segmental vapor ablation, an inflammatory response leads to tissue and volume reduction of the most diseased emphysematous segments. So far, BTVA has been demonstrated in several single-arm trials and 1 multinational randomized controlled trial to improve lung function, exercise capacity, and quality of life in patients with upper lobe-predominant emphysema irrespective of the collateral ventilation. In this review, we emphasize the practical aspects of this ELVR method. Patients with upper lobe-predominant emphysema, forced expiratory volume in 1 second (FEV1) between 20 and 45% of predicted, residual volume (RV) > 175% of predicted, and carbon monoxide diffusing capacity (DLCO) ≥20% of predicted can be considered for BTVA treatment. Prior to the procedure, a special software assists in identifying the target segments with the highest emphysema index, volume and the highest heterogeneity index to the untreated ipsilateral lung lobes. The procedure may be performed under deep sedation or preferably under general anesthesia. After positioning of the BTVA catheter and occlusion of the target segment by the occlusion balloon, heated water vapor is delivered in a predetermined specified time according to the vapor dose. After the procedure, patients should be strictly monitored to proactively detect symptoms of localized inflammatory reaction that may temporarily worsen the clinical status of the patient and to detect complications. As the data are still very limited, BTVA should be performed within clinical trials or comprehensive registries where the product is commercially available. © 2018 S. Karger AG, Basel.

Proximal or 'downhill' esophageal varices are a rare cause of upper gastrointestinal hemorrhage. Unlike the much more common distal esophageal varices, which are most commonly a result of portal hypertension, downhill esophageal varices result from vascular obstruction of the superior vena cava (SVC). While SVC obstruction is most commonly secondary to malignant causes, our review of the literature suggests that benign causes of SVC obstruction are the most common cause actual bleeding from downhill varices. Given the alternative pathophysiology of downhill varices, they require a unique approach to management. Variceal band ligation may be used to temporize acute variceal bleeding, and should be applied on the proximal end of the varix. Relief of the underlying SVC obstruction is the cornerstone of definitive treatment of downhill varices. A young woman with a benign superior vena cava stenosis due to a tunneled internal jugular vein dialysis catheter presented with hematemesis and melena. Urgent upper endoscopy revealed multiple 'downhill' esophageal varices with stigmata of recent hemorrhage. As there was no active bleeding, no endoscopic intervention was performed. CT angiography demonstrated stenosis of the SVC surrounding the distal tip of her indwelling hemodialysis catheter. The patient underwent balloon angioplasty of the stenotic SVC segment with resolution of her bleeding and clinical stabilization. Downhill esophageal varices are a distinct entity from the more common distal esophageal varices. Endoscopic therapies have a role in temporizing active variceal bleeding, but relief of the underlying SVC obstruction is the cornerstone of treatment and should be pursued as rapidly as possible. It is unknown why benign, as opposed to malignant, causes of SVC obstruction result in bleeding from downhill varices at such a high rate, despite being a less common etiology of SVC obstruction.

The aim of this study was to clarify whether dental floss clip (DFC) traction improves the technical outcomes of endoscopic submucosal dissection (ESD). A superiority, randomized control trial was conducted at 14 institutions across Japan. Patients with single gastric neoplasm meeting the indications of the Japanese guidelines for gastric treatment were enrolled and assigned to receive conventional ESD or DFC traction-assisted ESD (DFC-ESD). Randomization was performed according to a computer-generated random sequence with stratification by institution, tumor location, tumor size, and operator experience. The primary endpoint was ESD procedure time, defined as the time from the start of the submucosal injection to the end of the tumor removal procedure. Between July 2015 and September 2016, 640 patients underwent randomization. Of these, 316 patients who underwent conventional ESD and 319 patients who underwent DFC-ESD were included in our analysis. The mean ESD procedure time was 60.7 and 58.1 minutes for conventional ESD and DFC-ESD, respectively (P = .45). Perforation was less frequent in the DFC-ESD group (2.2% vs .3%, P = .04). For lesions located in the greater curvature of the upper or middle stomach, the mean procedure time was significantly shorter in the DFC-ESD group (104.1 vs 57.2 minutes, P = .01). Our findings suggest that DFC-ESD does not result in shorter procedure time in the overall patient population, but it can reduce the risk of perforation. When selectively applied to lesions located in the greater curvature of the upper or middle stomach, DFC-ESD provides a remarkable reduction in procedure time.

Nowadays, capsule endoscopy (CE) is the first-line procedure after negative upper and lower gastrointestinal (GI) endoscopy for obscure gastrointestinal bleeding (OGIB). Approximately, two-thirds of patients undergoing CE for OGIB will have a small-bowel abnormality. However, several patients who underwent CE for OGIB had the source of their blood loss in the stomach or in the colon. The aim of the present study is to determine the incidence of bleeding lesions missed by the previous gastroscopy/colonoscopy with CE and to evaluate the indication to repeat a new complete endoscopic workup in subjects related to a tertiary center for obscure bleeding before CE. We prospectively reviewed data from 637/1008 patients underwent to CE for obscure bleeding in our tertiary center after performing negative gastroscopy and colonoscopy. CE revealed a definite or likely cause of bleeding in stomach in 138/637 patients (yield 21.7%) and in the colon in 41 patients (yield 6.4%) with a previous negative gastroscopy and colonoscopy, respectively. The lesions found were outside the small bowel in only 54/637 (8.5%) patients. In 111/138 patients, CE found lesions both in stomach and small bowel (small-bowel erosions in 54, AVMs in 45, active small-bowel bleeding in 4, neoplastic lesions in 3 and distal ileum AVMs in 5 patients). In 24/41 (58.5%) patients, CE found lesions both in small bowel and colon (multiple small-bowel erosions in 15; AVMs in 8 and neoplastic lesion in 1 patients. All patients underwent endoscopic therapy or surgery for their nonsmall-bowel lesions. Lesions in upper or lower GI tract have been missed in about 28% of patients submitted to CE for obscure bleeding. CE may play an important role in identifying lesions missed at conventional endoscopy.

To report the effect of unilateral laser vocal cordectomy on respiratory noise and airway function in horses with experimentally induced laryngeal hemiplegia (LH). Experimental study. Six Standardbred horses without upper airway abnormalities at rest or during high-speed treadmill exercise. Respiratory sounds and inspiratory trans-upper airway pressure (P(Ui)) were measured before (baseline) and 14 days after induction of LH by left recurrent laryngeal neurectomy, and again 30, 60, 90, and 120 days after endoscopically assisted laser cordectomy of the left vocal cord. Data were collected with the horses exercising on a treadmill at a speed producing maximum heart rate (HR(max)). In horses exercising at HR(max), induction of LH caused a significant increase in P(Ui), sound level (SL), and the sound intensity of formant 2 (F(2)) and 3 (F(3)). The sound intensity of formant 1 (F(1)) was unaffected by induction of LH. Laser vocal cordectomy had no effect on SL, or on the sound intensity of F(1) and F(3). At 30, 60, 90, and 120 days after surgery, P(Ui) and the sound intensity of F(2) were significantly reduced, but these variables remained significantly different from baseline values. Unilateral laser vocal cordectomy did not effectively improve upper airway noise in horses with LH. The procedure decreased upper airway obstruction to the same degree as bilateral ventriculocordectomy. Currently, laser vocal cordectomy cannot be recommended for the treatment of upper airway noise in horses with LH.

In patients with acute nonvariceal upper gastrointestinal bleeding, rebleeding after an initial treatment is observed in 10-20% and is associated with mortality. To investigate whether the initial serum C-reactive protein level could predict the risk of rebleeding in patients with acute nonvariceal upper gastrointestinal bleeding. This was a retrospective study using prospectively collected data for upper gastrointestinal bleeding. Initial clinical characteristics, endoscopic features, and C-reactive protein levels were compared between those with and without 30-day rebleeding. A total of 453 patients were included (mean age, 62 years; male, 70.9%). The incidence of 30-day rebleeding was 15.9%. The mean serum C-reactive protein level was significantly higher in these patients than in those without rebleeding (P<0.001). The area under the receiver operating characteristics curve with a cutoff value of 0.5mg/dL was 0.689 (P<0.001). High serum C-reactive protein level (odds ratio, 2.98; confidence interval, 1.65-5.40) was independently associated with the 30-day rebleeding risk after adjustment for the main confounding risk factors, including age, blood pressure, and initial haemoglobin level. The serum C-reactive protein was an independent risk factor for 30-day rebleeding in patients with acute nonvariceal upper gastrointestinal bleeding, indicating a possible role as a useful screening indicator for predicting the risk of rebleeding.

To implement an online, prospective collection of clinical data and outcome of patients with acute nonvariceal upper gastrointestinal bleeding (UGIB) in Italy ("Prometeo" study). Epidemiology, clinical features, and outcomes of nonvariceal UGIB are mainly known by retrospective studies and are probably changing. Data were collected by 13 Gastrointestinal Units in Italy from June 2006 to June 2007 (phase 1) and from December 2008 to December 2009 (phase 2): an interim analysis of data was performed between the 2 phases to optimize the online database. All the patients consecutively admitted for acute nonvariceal UGIB were enrolled. Demographic and clinical data were collected, a diagnostic endoscopy performed, with endoscopic hemostasis if indicated. One thousand four hundred thirteen patients (M=932, mean age±SD=66.5±15.8; F=481, mean age±SD=74.2±14.6) were enrolled. Comorbidities were present in 83%. 52.4% were treated with acetyl salicylic acid or other nonsteroidal anti-inflammatory drugs (NSAIDs): only 13.9% had an effective gastroprotection. Previous episodes of UGIB were present in 13.3%. Transfusion were needed in 43.9%. Shock was present in 9.3%. Endoscopic diagnosis was made in 93.2%: peptic lesions were the main cause of bleeding (duodenal ulcer 36.2%, gastric ulcer 29.6%, gastric/duodenal erosions 10.9%). At endoscopy, Helicobacter pylori was searched in 37.2%, and found positive in 51.3% of tested cases. Early rebleeding was observed in 5.4%: surgery was required in 14.3% of them. Bleeding-related death occurred in 4.0%: at multivariate analysis, the risk of death was correlated with female sex [odds ratio (OR=2.19, P=0.0089)], presence of neoplasia (OR=2.70, P=0.0057) or multiple comorbidities (OR=5.04, P=0.0280), shock at admission (OR=4.55, P=0.0001), and early rebleeding (OR=1.47, P=0.004). Prometeo database has provided an up-to-date picture of acute nonvariceal UGIB in Italy: patients are elderly, predominantly males, and with important comorbidities. Gastroprotection is underutilized during NSAIDs treatment. With respect to previous studies, Prometeo shows a higher incidence of low-dose acetyl salicylic acid use and comorbidities, whereas no significant difference were found in other items (etiology of bleeding, NSAIDs use, need for endoscopic hemostasis, incidence of rebleeding, and overall mortality).

Sleeve gastrectomy (SG) is currently the most commonly performed bariatric procedure in France. It achieves both adequate excess weight loss and significant reduction in comorbidities. However, fistula is still the most common complication after SG, occurring in more than 3 % of cases, even in specialized centers (Gagner and Buchwald in Surg Obes Relat Dis 10:713-723. doi: 10.1016/j.soard.2014.01.016 , 2014). Its management is not standardized, long, and challenging. We have already reported the short-term results of Roux-en-Y fistulo-jejunostomy (RYFJ) as a salvage procedure in patients with post-SG fistula (Chouillard et al. in Surg Endosc 28:1954-1960 doi: 10.1007/s00464-014-3424-y , 2014). In this study, we analyzed the mid-term results of the RYFJ emphasizing its endoscopic, radiologic, and safety outcome. Between January 2007 and December 2013, we treated 75 patients with post-SG fistula, mainly referred from other centers. Immediate management principles included computerized tomography (CT) scan-guided drainage of collections or surgical peritoneal lavage, nutritional support, and endoscopic stenting. Ultimately, this approach achieved fistula control in nearly two-thirds of the patients. In the remaining third, RYFJ was proposed, eventually leading to fistula control in all cases. The mid-term results (i.e., more than 1 year after surgery) were assessed using anamnesis, clinical evaluation, biology tests, upper digestive tract endoscopy, and IV-enhanced CT scan with contrast upper series. Thirty patients (22 women and 8 men) had RYFJ for post-SG fistula. Mean age was 40 years (range 22-59). Procedures were performed laparoscopically in all but 3 cases (90 %). Three patients (10 %) were lost to follow-up. Mean follow-up period was 22 months (18-90). Mean body mass index (BMI) was 27.4 kg/m(2) (22-41). Endoscopic and radiologic assessment revealed no persistent fistula and no residual collections. Despite the lack of long-term follow-up, RYFJ could be a safe and feasible salvage option for the treatment of patients with post-SG fistula, especially those who failed conservative management. Mid-term outcome analysis confirms that fistula control is durable. Weight loss panel is satisfactory.

Self-expandable metal stents (SEMSs) can be used for the palliation of malignant obstruction in the upper gastrointestinal tract. This study assessed the feasibility and efficacy of endoscopically inserted SEMSs for the palliation of malignant obstruction in the stomach and duodenum. Between January 2011 and April 2014, 220 patients with gastric or duodenal obstruction due to malignancy underwent endoscopic SEMS insertion at Asan Medical Center. The associations of technical/clinical outcomes and complications with the type of stent and site of obstruction were analyzed. The 220 patients included 125 men (56.8 %) and 95 women (43.2 %); median patient age was 63 years. Fully covered, partially covered, and uncovered SEMSs were inserted into 16, 77, and 120 patients, respectively. Obstructions were located in the gastric outlet, including the duodenal bulb, in 106 patients, and in the duodenal second and third portions in 114 patients. Technical success was achieved in 213 of 220 patients (96.8 %) and clinical success in 184 of 213 (86.4 %). Clinical success rates were similar to the type of stent, but were significantly greater for gastric outlet (95/104, 91.3 %) than for duodenal (89/109, 81.7 %) obstructions (p = 0.039). Stent migration was observed in 20 patients (9.1 %) and stent obstruction in 51 (23.2 %). Rates of stent migration were significantly higher for fully covered (6/16, 37.5 %) than for partially covered (7/77, 9.1 %) and uncovered (7/120, 5.8 %) SEMSs (p < 0.001) and were significantly higher for gastric outlet (16/104, 15.4 %) than for duodenal (4/109, 1.2 %) obstructions (p = 0.003). Rates of stent obstruction were similar for fully covered (2/16, 12.5 %), partially covered (17/77, 22.1 %), and uncovered (32/120, 26.7 %) SEMSs (p = 0.409) and in patients with gastric outlet (26/104, 25.0 %) and duodenal (25/109, 22.9 %) obstruction (p = 0.724). SEMS selection for malignant obstruction of the upper gastrointestinal tract depends on the site of obstruction.

Despite extensive worldwide use of standard esophagogastroduodenoscopy (EGD) examinations, gastric cancer (GC) is one of the most common forms of cancer and ranks as the most common malignant tumor in East Asia, Eastern Europe and parts of Latin America. Current limitations of using non systematic examination during standard EGD could be at least partially responsible for the low incidence of early GC diagnosis in countries with a high prevalence of the disease. Originally proposed by Emura et al., systematic alphanumeric-coded endoscopy (SACE) is a novel method that facilitates complete examination of the upper GI tract based on sequential systematic overlapping photo-documentation using an endoluminal alphanumeric-coded nomenclature comprised of eight regions and 28 areas covering the entire surface upper GI surface. For precise localization or normal or abnormal areas, SACE incorporates a simple coordinate system based on the identification of certain natural axes, walls, curvatures and anatomical endoluminal landmarks. Efectiveness of SACE was recently demonstrated in a screening study that diagnosed early GC at a frequency of 0.30% (2/650) in healthy, average-risk volunteer subjects. Such a novel approach, if uniformly implemented worldwide, could significantly change the way we practice upper endoscopy in our lifetimes.

To determine risk factors associated with mortality and increased drug costs in patients with nonvariceal upper gastrointestinal bleeding. We retrospectively analyzed data from patients hospitalized with nonvariceal upper gastrointestinal bleeding between January 2001-December 2011. Demographic and clinical characteristics and drug costs were documented. Univariate analysis determined possible risk factors for mortality. Statistically significant variables were analyzed using a logistic regression model. Multiple linear regression analyzed factors influencing drug costs. p < 0.05 was considered statistically significant. The study included data from 627 patients. Risk factors associated with increased mortality were age > 60, systolic blood pressure<100 mmHg, lack of endoscopic examination, comorbidities, blood transfusion, and rebleeding. Drug costs were higher in patients with rebleeding, blood transfusion, and prolonged hospital stay. In this patient cohort, re-bleeding rate is 11.20% and mortality is 5.74%. The mortality risk in patients with comorbidities was higher than in patients without comorbidities, and was higher in patients requiring blood transfusion than in patients not requiring transfusion. Rebleeding was associ-ated with mortality. Rebleeding, blood transfusion, and prolonged hospital stay were associated with increased drug costs, whereas bleeding from lesions in the esophagus and duodenum was associated with lower drug costs.

Guidelines issued by the Association of Operating Room Nurses and the Association of Professionals in Infection Control and Epidemiology recommend high-level disinfection (HLD) for semicritical instruments, such as flexible endoscopes. We aim to examine the durability of endoscopes to continued use and automated HLD. We report the number of duty cycles a flexible endoscope can withstand before repairs should be anticipated. Retrospective review. A total of 4,336 endoscopic exams and subsequent disinfection cycles were performed with 60 flexible endoscopes in an outpatient tertiary pediatric otolaryngology practice from 2005 to 2009. All endoscopes were systemically cleaned with mechanical cleansing followed by leak testing, enzymatic cleaning, and exposure to Orthophthaldehyde (0.55%) for 5 minutes at a temperature of at least 25°C, followed by rinsing for 3 minutes. A total of 77 repairs were performed, 48 major (average cost $3,815.97), and 29 minor (average cost $326.85). On average, the 2.2-mm flexible endoscopes were utilized for 61.9 examinations before major repair was needed, whereas the 3.6 mm endoscopes were utilized for 154.5 exams before needing minor repairs. No major repairs have been needed to date on the 3.6-mm endoscopes. Automated endoscope reprocessor use for HLD is an effective means to disinfect and process flexible endoscopes. This minimizes variability in the processing of the endoscopes and maximizes the rate of successful HLD. Even when utilizing standardized, automated HLD and limiting the number of personnel processing the endoscopes, smaller fiberoptic endoscopes demonstrate a shortened time interval between repairs than that seen with the larger endoscopes.

The present study was carried out in the context of current discussions concerning ways in which simulation systems can be integrated sensibly and effectively into clinical educational structures, in order to shorten the training period for assistants and reduce potential risks for the patient. In our study, a number of centers used a standardized training approach, in 1 week courses, to investigate the learning curve improvement that can be achieved with a group of beginners in upper gastroduodenal endoscopy. The multicenter study used the Erlangen Endo-Trainer, with specially prepared biological specimens from pigs. Using this, the individual steps of diagnostic upper gastrointestinal endoscopy with biopsy can be carried out following a score-card system. After a theoretical introduction and a demonstration of the examination by an experienced endoscopist, an initial evaluation score for each participant was obtained on day 1. On the following days, the program consisted of 2 hours' training by a tutor, followed by a test run for each participant. On days 1, 2, 3, 4, and 5 the test run was directly followed by a self-assessment. In addition, on days 1, 3, and 5 the test run for each beginner was recorded on video, with each video assigned an encrypted code number. All the end of the study week, control assessments of these videos were carried out by an experienced endoscopist. Both the self-assessments and the control assessments showed significant improvements in the endoscopic parameters tested during the course (days 1-5; all parameters P < 0.001, Wilcoxon-test). However, it was found that the trainees tended to give themselves better marks than the marks given by experienced endoscopists. During 1 week of training, using the model and following the score card, a significant improvement in the learning curve was achieved in the beginners' group for the individual steps involved in diagnostic upper gastrointestinal endoscopy. When this approach is used with trainees who are also provided with the necessary theoretical background, this type of preparation may lead to a better, lower-risk start to supervised practical endoscopic examinations in patients.
[Watermelon stomach: Chronic renal failure and/or imatinib?].

Watermelon stomach or gastric antral vascular ectasia (GAVE) syndrome is an uncommon cause of sometimes severe upper gastro-intestinal bleeding. Essentially based on a pathognomonic endoscopic appearance, its diagnosis may be unrecognised because mistaken with portal hypertensive gastropathy, while treatment of these two entities is different. Its etiopathogeny remains still unclear, even if it is frequently associated with different systemic illnesses as hepatic cirrhosis, autoimmune disorders and chronic renal failure. The mechanism inducing these vascular ectasia may be linked with mechanical stress on submucosal vessels due to antropyloric peristaltic motility dysfunction modulated by neurohormonal vasoactive alterations. Because medical therapies are not very satisfactory, among the endoscopic modalities, argon plasma coagulation seems to be actually the first-line treatment because the most effective and safe. However, surgical antrectomy may be sometimes necessary. Recently GAVE syndrome appeared as a new adverse reaction of imatinib mesylate, one of the tyrosine kinase inhibitors used in chronic myeloid leukemia, and we report here the observation of such a pathology in one patient treated at the same time by haemodialysis and by imatinib mesylate for chronic myeloid leukemia.

AIM: To determine the prevalence and risk factors of work-related musculoskeletal disorders in gastrointestinal endoscopists in Korea. METHODS: A survey of musculoskeletal symptoms, using a self-administered questionnaire, was conducted on 55 endoscopists practicing in general hospitals or health promotion centers. RESULTS: Forty-nine (89.1%) endoscopists reported musculoskeletal pain on at least one anatomic location and 37 (67.3%) endoscopists complained of pain at rest. Twenty-six (47.3%) endoscopists had severe musculoskeletal pain defined as a visual analogue score greater than 5.5. Factors related to the development of severe pain were (1) standing position during upper endoscopy, (2) specific posture/habit during endoscopic procedures, and (3) multiple symptomatic areas. Finger pain was more common in beginners, whereas shoulder pain was more common in experienced endoscopists. Sixteen percent of symptomatic endoscopists have modified their practice or reduced the number of endoscopic examinations. Only a few symptomatic endoscopists had sought professional consultation with related specialists. CONCLUSION: The prevalence of musculoskeletal pain in endoscopists is very high. The location of pain was different between beginners and experienced endoscopists. Measures for the prevention and adequate management of endoscopy-related musculoskeletal symptoms are necessary.

Current issues and future perspectives of gastric cancer screening
Hamashima, Chisato
2014-01-01
Gastric cancer remains the second leading cause of cancer death worldwide. About half of the incidence of gastric cancer is observed in East Asian countries, which show a higher mortality than other countries. The effectiveness of 3 new gastric cancer screening techniques, namely, upper gastrointestinal endoscopy, serological testing, and “screen and treat” method were extensively reviewed. Moreover, the phases of development for cancer screening were analyzed on the basis of the biomarker development road map. Several observational studies have reported the effectiveness of endoscopic screening in reducing mortality from gastric cancer. On the other hand, serologic testing has mainly been used for targeting the high-risk group for gastric cancer. To date, the effectiveness of new techniques for gastric cancer screening has remained limited. However, endoscopic screening is presently in the last trial phase of development before their introduction to population-based screening. To effectively introduce new techniques for gastric cancer screening in a community, incidence and mortality reduction from gastric cancer must be initially and thoroughly evaluated by conducting reliable studies. In addition to effectiveness evaluation, the balance of benefits and harms must be carefully assessed before introducing these new techniques for population-based screening. PMID:25320514

We describe an ultrahigh speed endoscopic swept source optical coherence tomography (OCT) system for clinical gastroenterology using a vertical-cavity surface-emitting laser (VCSEL) and micromotor imaging catheter. The system had a 600 kHz axial scan rate and 8 µm axial resolution in tissue. Imaging was performed with a 3.2 mm diameter imaging catheter at 400 frames per second with a 12 µm spot size. Three-dimensional OCT (3D-OCT) imaging was performed in patients with a cross section of pathologies undergoing upper and lower endoscopy. The use of distally actuated imaging catheters enabled OCT imaging with more flexibility, such as volumetric imaging in the small intestine and the assessment of hiatal hernia using retroflex imaging. The high rotational scanning stability of the micromotor enabled 3D volumetric imaging with micron scale volumetric accuracy for both en face OCT and cross-sectional imaging, as well as OCT angiography (OCTA) for 3D visualization of subsurface microvasculature. The ability to perform both structural and functional 3D OCT imaging in the GI tract with microscopic accuracy should enable a wide range of studies and enhance the sensitivity and specificity of OCT for detecting pathology.

Craniocervical junction pathology is infrequent in daily neurosurgical practice. In general, most of these lesions are of traumatic or rheumatic origin. Atlantoaxial instability of inflammatory origin (Grisel syndrome) is a rare entity of which only 16 adult cases have been reported in the literature. This pathology is characterized by the development of an osteolytic lesion at the level of the atlantoaxial joint after an infectious event, usually of the upper airways. We present the case of a 76-year-old patient who attended our office for clinical symptoms of spinal instability secondary to an osteolytic lesion, with involvement of C1 and C2. The symptomatology began after an infectious respiratory process. A posterior cervical occiput fixation and an endoscopic transnasal odontoidectomy with anterior decompression were performed. The patient evolved with complete resolution of symptoms. The cultures were negative, and the pathological anatomy study concluded nonspecific inflammatory changes. Until a few years ago, the only option to address this pathology was the transoral pathway with microsurgical technique. Nowadays, endoscopy offers many technical advantages. This is an option to be considered when planning approaches to craniocervical junction.

Overweight can be a risk factor for pathological gastroesophageal reflux or hiatal hernia. To study the prevalence of gastroesophageal reflux in patients with severe obesity. Sixty seven patients, 51 female, aged 17 to 56 years old with a body mass index over 35 kg/m2, were studied. An upper gastrointestinal endoscopy was performed in all, esophageal manometry was done in 32 and 24 h pH monitoring was done in 32 patients. Seventy nine percent of patients complained of heartburn and 66% of regurgitation. In 16 patients, endoscopy was normal. An erosive esophagitis was found in 33 patients, a short columnar epithelium in 12 and a Barret esophagus with intestinal metaplasia in six. Normal endoscopic findings and erosive esophagitis were present with a higher frequency in women. No association between the degree of obesity and esophageal lesions was observed. Lower esophageal sphincter pressure and abdominal length were significantly higher in subjects with a body mass index over 50 compared to those with a body mass index between 35 and 39.9 kg/m2. No differences were observed in 24 h pH monitoring. A high proportion of severely obese patients had symptoms and endoscopical findings of pathological gastroesophageal reflux.
Gastroscopy: a primary diagnostic procedure.
Coleman, W H
1988-03-01
EGD, using 1986 models of either the fiberoptic gastroscope or the videoscope, is a safe and accurate procedure that can be performed by any physician trained in the technique of endoscope passage. It may be performed at large medical centers or small rural hospitals, outpatient clinics, or even private offices. Patients themselves have indicated preference for endoscopic evaluation over the double-contrast barium meal after they have experienced both procedures. The short time of procedure, its accuracy, safety, and its relative lack of discomfort to the patient lend it readily to being an initial component in the primary evaluation of symptoms of abdominal distress, gastrointestinal bleeding, dysphagia, esophageal reflux, persistent vomiting, and odynophagia. It is essential in the evaluation of complications of esophageal reflux and the evaluation of abnormal radiological findings in the upper gastrointestinal tract. It should never be overlooked in evaluating the patient with iron deficiency anemia of unknown etiology. Economic pressures have already moved EGD from the surgery wards to endoscopy labs and to the outpatient setting. These same forces will project more physicians into the role of the diagnostic endoscopist and the patient will benefit by decreased medical costs, quicker diagnosis and treatment, and enhanced continuity of care.

A 66-year-old woman was admitted to our clinic for appetite loss and abdominal distension in August 1995. Endoscopic study revealed an advanced gastric cancer in the upper body of her stomach. Abdominal CT study revealed massive ascites and para-aortic lymph nodal involvement. Cytological study of the ascites revealed class V. She was diagnosed to be in the terminal stage of gastric cancer with carcinomatosa peritonitis. Combination chemotherapy with 5-fluorouracil (5-FU) and low-dose cisplatin (CDDP) was given by continuous intravenous injection of 5-FU 500 mg/day, and intermittent intravenous injection of CDDP 30 mg/week was performed for reduction of the ascites and her complaint. Endoscopic study 6 weeks after starting chemotherapy could not find crater of the gastric cancer but only a shallow ulcerative lesion. The biopsy specimen of that lesion was group III. No ascites and over 50% reduction of the para-aortic lymph node were found by the abdominal CT study. This state persisted over 4 weeks. No myelo-suppression, renal dysfunction or any severe side effect were observed during chemotherapy. Her performance status improved from 3 to 1.

A 39-year-old woman visited our hospital because of epigastric pain. Gastrointestinal endoscopy revealed a gastric submucosal tumor, 30mm in size, with ulcer locating near to the esophagogastric junction, and it was diagnosed with GIST by the endoscopic ultrasonography-guided fine needle aspiration. Then, she underwent laparoscopic surgery for the removal of gastric GIST. After peeling around the upper stomach, the local resection of the stomach was performed with linear staplers in the minor axis direction under the vision of the endoscope and laparoscope. Histopathological examinations confirmed that the tumor was GIST with an intermediate risk, and all surgical margins were free of GIST cells. Local resection with the laparoscopy endoscopy cooperative surgery(LECS)technique is a very useful way of the removal of gastric GISTs locating near to the esophagogastric junction in terms of the remnant gastric functions. Meanwhile, because the standard LECS requires the opening of the gastric lumen, there remains concerns about the intraperitoneal tumor dissemination for the gastric GIST with ulcer. We herein reported a case of laparoscopic local resection for a gastric GIST with ulcer locating near to the esophagogastric junction without gastric opening.

Purpose Gastric mucosal neoplastic lesions should have characteristic endoscopic features for successful endoscopic submucosal dissection. Materials and Methods Out of the 1,010 endoscopic submucosal dissection, we enrolled 62 patients that had the procedure cancelled. Retrospectively, whether the reasons for cancelling the endoscopic submucosal dissection were consistent with the indications for an endoscopic submucosal dissection were assessed by analyzing the clinical outcomes of the patients that had the surgery. Results The cases were divided into two groups; the under-diagnosed group (30 cases; unable to perform an endoscopic submucosal dissection) and the over-diagnosed group (32 cases; unnecessary to perform an endoscopic submucosal dissection), according to the second endoscopic findings, compared with the index conventional white light image. There were six cases in the under-diagnosed group with advanced gastric cancer on the second conventional white light image endoscopy, 17 cases with submucosal invasion on endoscopic ultrasonography findings, 5 cases with a size greater than 3 cm and ulcer, 1 case with diffuse infiltrative endoscopic features, and 1 case with lymph node involvement on computed tomography. A total of 25 patients underwent a gastrectomy to remove a gastric adenocarcinoma. The overall accuracy of the decision to cancel the endoscopic submucosal dissection was 40% (10/25) in the subgroup that had the surgery. Conclusions The accuracy of the decision to cancel the endoscopic submucosal dissection, after conventional white light image and endoscopic ultrasonography, was low in this study. Other diagnostic options are needed to arrive at an accurate decision on whether to perform a gastric endoscopic submucosal dissection. PMID:22792522

The use of computer simulation to develop a high-fidelity model has been proposed as a novel and cost-effective alternative to help guide therapeutic intervention in sleep apnea surgery. We describe a computer model based on patient-specific anatomy of obstructive sleep apnea (OSA) subjects wherein the percentage and sites of upper airway collapse are compared to findings on drug-induced sleep endoscopy (DISE). Basic science computer model generation. Three-dimensional finite element techniques were undertaken for model development in a pilot study of four OSA patients. Magnetic resonance imaging was used to capture patient anatomy and software employed to outline critical anatomical structures. A finite-element mesh was applied to the volume enclosed by each structure. Linear and hyperelastic soft-tissue properties for various subsites (tonsils, uvula, soft palate, and tongue base) were derived using an inverse finite-element technique from surgical specimens. Each model underwent computer simulation to determine the degree of displacement on various structures within the upper airway, and these findings were compared to DISE exams performed on the four study patients. Computer simulation predictions for percentage of airway collapse and site of maximal collapse show agreement with observed results seen on endoscopic visualization. Modeling the upper airway in OSA patients is feasible and holds promise in aiding patient-specific surgical treatment. NA.

The preoperative diagnosis of T stage is important in selecting limited treatments, such as laparoscopic proximal gastrectomy (LPG), which lacks the ability to palpate the tumor. Therefore, the present study examined the accuracy of preoperative diagnosis of the depth of tumor invasion in early gastric cancer from the view point of the indication for LPG. A total of 193 patients with cT1 gastric cancer underwent LPG with gastrointestinal endoscopic examinations and a series of upper gastrointestinal radiographs. The patients with pT1 were classified into the correctly diagnosed group (163 patients, 84.5%), and those with pT2 or deeper were classified into the underestimated group (30 patients, 15.5%). Factors that were associated with underestimation of tumor depth were analyzed. Tumor size in the underestimated group was significantly larger; the lesions were more frequently located in the upper third of the stomach and were more histologically diffuse, scirrhous, with infiltrative growth, and more frequent lymphatic and venous invasion. For upper third lesions, in univariate analysis, histology (diffuse type) was associated with underestimation of tumor depth. Multivariate analysis found that tumor size (≥20 mm) and histology (diffuse type) were independently associated with underestimation of tumor depth. gastric cancer in the upper third of the stomach with diffuse type histology and >20 mm needs particular attention when considering the application of LPG.

We herein describe the case of a 67-year-old woman with a duodenal ulcer thought to be caused by elevated pancreatic ductal pressure. The patient complained of continuous upper abdominal pain. Her medical history included idiopathic chronic pancreatitis. Endoscopy revealed a huge duodenal ulcer located on the inferior duodenal angle, which had not been seen on endoscopic retrograde pancreatography two months previously. A combination study using endoscopy and contrast imaging confirmed the relationship between the duodenal ulcer and the pancreatic branch duct. To our knowledge, this is the first case of duodenal ulcer thought to be caused by elevated pancreatic ductal pressure.
Acute Necrotizing Esophagitis Followed by Duodenal Necrosis
del Hierro, Piedad Magdalena
2011-01-01
Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved. PMID:27957030
Methemoglobinemia and benzocaine.
Moos, Daniel D; Cuddeford, James D
2007-01-01
Benzocaine administration to facilitate upper endoscopic procedures can result in the relatively uncommon but potentially fatal complication known as methemoglobinemia. For this reason, the Veterans Health Administration (VA) announced on February 8, 2006, that they would stop using benzocaine-containing sprays for procedures involving the mouth and throat. Methemoglobinemia should be considered in any patient who demonstrates cyanosis, respiratory distress, headache, lightheadedness, and a dark, chocolate-colored blood after receiving pharyngeal anesthesia. Prompt recognition of this rare (but potentially fatal) condition is important. Once identified, treatment is generally rapid with methylene blue. The patient should be monitored in the intensive care setting for recurrence. Knowledge of this adverse medication reaction is essential for all gastroenterology nurses.
Endoscopic management of foreign bodies in the upper gastrointestinal tract: A review
Sugawa, Choichi; Ono, Hiromi; Taleb, Mona; Lucas, Charles E
2014-01-01
Foreign body ingestion is a common condition, especially among children who represent 80% of these emergencies. The most frequently ingested foreign bodies in children are coins, toys, magnets and batteries. Most foreign body ingestions in adults occur while eating, leading to either bone or meat bolus impaction. Flexible endoscopy is the therapeutic method of choice for relieving food impaction and removing true foreign bodies with a success rate of over 95% and with minimal complications. This review describes a comprehensive approach towards patients presenting with foreign body ingestion. Recommendations are based on a review of the literature and extensive personal experience.

We report here the case of a 65-year-old woman who suffered intraperitoneal sclerosant leakage after endoscopic injection sclerotherapy for bleeding gastric varices. In total, 3 ml of N-butyl-2-cyanoacrylate and Lipiodol mixture was injected. The patient developed mild fever and pain over the left upper quadrant and flank after the procedure. In addition to a Lipiodol-filled gastric varix, the imaging studies disclosed a wide spread of Lipiodol over the left peritoneal cavity. The patient was kept fasting with parenteral antibiotics and nutrition. She responded well to the treatment, and all of the symptoms had subsided 6 days later.

Upper gastrointestinal bleeding (UGIB) is defined as bleeding that results from lesions located above the ligament of Treitz and is a common cause for emergency hospital admissions in patients with gastrointestinal disorders. UGIB also increases the risk of morbidity and mortality in patients already hospitalized for other reasons. According to epidemiological surveys of acute UGIB in Iran, peptic ulcer is the most common endoscopic diagnosis. Gastric and duodenal erosion accounts for 16.4%-25% of etiologies. Other relatively common causes of UGIB are variceal hemorrhage, Mallory-Weiss tears, and arterial and venous malformations. However, in 9%-13.3% of patients, the endoscopy is normal. PMID:24829656

The current International Organization for Standardization (ISO) standard (ISO 8600-3: 1997 including Amendment 1: 2003) for determining endoscope field of view (FOV) does not accurately characterize some novel endoscopic technologies such as endoscopes with a close focus distance and capsule endoscopes. We evaluated the endoscope FOV measurement method (the FOV WS method) in the current ISO 8600-3 standard and proposed a new method (the FOV EP method). We compared the two methods by measuring the FOV of 18 models of endoscopes (one device for each model) from seven key international manufacturers. We also estimated the device to device variation of two models of colonoscopes by measuring several hundreds of devices. Our results showed that the FOV EP method was more accurate than the FOV WS method, and could be used for all endoscopes. We also found that the labelled FOV values of many commercial endoscopes are significantly overstated. Our study can help endoscope users understand endoscope FOV and identify a proper method for FOV measurement. This paper can be used as a reference to revise the current endoscope FOV measurement standard.

Khan, Mubarak M; Parab, Sapna R
2016-06-01
The well established techniques in tympanoplasty are routinely performed with operating microscopes for many decades now. Endoscopic ear surgeries provide minimally invasive approach to the middle ear and evolving new science in the field of otology. The disadvantage of endoscopic ear surgeries is that it is one-handed surgical technique as the non-dominant left hand of the surgeon is utilized for holding and manipulating the endoscope. This necessitated the need for development of the endoscope holder which would allow both hands of surgeon to be free for surgical manipulation and also allow alternate use of microscope during tympanoplasty. To report the preliminary utility of our designed and developed endoscope holder attachment gripping to microscope for two handed technique of endoscopic tympanoplasty. Prospective Non Randomized Clinical Study. Our endoscope holder attachment for microscope was designed and developed to aid in endoscopic ear surgery and to overcome the disadvantage of single handed endoscopic surgery. It was tested for endoscopic Tympanoplasty. The design of the endoscope holder attachment is described in detail along with its manipulation and manoeuvreing. A total of 78 endoholder assisted type 1 endoscopic cartilage tympanoplasties were operated to evaluate its feasibility for the two handed technique and to evaluate the results of endoscopic type 1 cartilage tympanoplasty. In early follow up period ranging from 6 to 20 months, the graft uptake was seen in 76 ears with one residual perforation and 1 recurrent perforations giving a success rate of 97.435 %. Our endocsope holder attachment for gripping microscope is a good option for two handed technique in endoscopic type 1 cartilage tympanoplasty. The study reports the successful application and use of our endoscope holder attachment for gripping microscope in two handed technique of endoscopic type 1 cartilage tympanoplasty and comparable results with microscopic techniques.

Background Endoscopic technique is often applied for the diagnosis of diseases affecting internal organs and image-guidance of surgical procedures. Although the endoscope has become an indispensable tool in the clinic, its utility has been limited to medical offices or operating rooms because of the large size of its ancillary devices. In addition, the basic design and imaging capability of the system have remained relatively unchanged for decades. Objective The objective of this study was to develop a smartphone-based endoscope system capable of advanced endoscopic functionalities in a compact size and at an affordable cost and to demonstrate its feasibility of point-of-care through human subject imaging. Methods We developed and designed to set up a smartphone-based endoscope system, incorporating a portable light source, relay-lens, custom adapter, and homebuilt Android app. We attached three different types of existing rigid or flexible endoscopic probes to our system and captured the endoscopic images using the homebuilt app. Both smartphone-based endoscope system and commercialized clinical endoscope system were utilized to compare the imaging quality and performance. Connecting the head-mounted display (HMD) wirelessly, the smartphone-based endoscope system could superimpose an endoscopic image to real-world view. Results A total of 15 volunteers who were accepted into our study were captured using our smartphone-based endoscope system, as well as the commercialized clinical endoscope system. It was found that the imaging performance of our device had acceptable quality compared with that of the conventional endoscope system in the clinical setting. In addition, images captured from the HMD used in the smartphone-based endoscope system improved eye-hand coordination between the manipulating site and the smartphone screen, which in turn reduced spatial disorientation. Conclusions The performance of our endoscope system was evaluated against a commercial system in routine otolaryngology examinations. We also demonstrated and evaluated the feasibility of conducting endoscopic procedures through a custom HMD. PMID:28751302

Intraluminal erosion of a laparoscopic gastric band into the stomach has been reported as a complication of laparoscopic adjustable gastric banding. To our knowledge, however, intraluminal erosion of the band tubing into the duodenum has not been described. We report a 46-year-old man in whom a laparoscopic adjustable gastric band tubing eroded into the duodenal lumen, causing recurrent port-site infections. This complication was diagnosed on upper endoscopy and also, in retrospect, on an upper gastrointestinal barium study and computed tomography. The patient underwent surgical removal of the band and tubing, with a primary duodenal repair, and made a complete recovery without complications. Erosion of laparoscopic band tubing into the duodenum should be included in the differential diagnosis for recurrent port-site infections after laparoscopic adjustable gastric banding. Radiographic or endoscopic visualization of the intraluminal portion of the tubing may be required for confirmation. Definitive treatment of this complication entails surgical removal of the tubing from the duodenum.

Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a common medical emergency that can be life threatening. This study evaluated predictive factors of 30-day mortality in patients with this condition. A prospective observational study was conducted at a single hospital between April 2010 and November 2012, and 336 patients with symptoms and signs of gastrointestinal bleeding were consecutively enrolled. Clinical characteristics and endoscopic findings were reviewed to identify potential factors associated with 30-day mortality. Overall, 184 patients were included in the study (men, 79.3%; mean age, 59.81 years), and 16 patients died within 30 days (8.7%). Multivariate analyses revealed that comorbidity of diabetes mellitus (DM) or metastatic malignancy, age ≥ 65 years, and hypotension (systolic pressure < 90 mmHg) during hospitalization were significant predictive factors of 30-day mortality. Comorbidity of DM or metastatic malignancy, age ≥ 65 years, and hemodynamic instability during hospitalization were predictors of 30-day mortality in patients with NVUGIB. These results will help guide the management of patients with this condition.

Breathing vitally serves body homeostasis. The prevalence of upper airway infections is often taken as an indicator of overall health status of a population living at a given time. In the present study we examined the unearthed remains of skulls from the XIII-XV century inhabitants searching for signs of maxillary sinusitis. Maxillary sinuses of the skulls of 92 individuals were inspected macroscopically and, if necessary, endoscopically. Osseous changes, including the pitting and abnormal spicule formation were present in 69 cases (75.0 %). It was found that, overall, dental infection was a major cause of maxillary sinusitis (18.8 %). Severe bone changes were observed in the adults' skulls, but were also present in the sinus walls of children's skulls. Post-inflammatory changes were manifest as remodeling and damage to the sinus walls. The results indicate that both children and adults of the Middle Ages suffered from chronic sinusitis. These observations confirm that the climate, environment, and lifestyle of the medieval populations contributed to the morbidity of the upper respiratory tract.
Use of a chain écraseur for excision of a pharyngeal granuloma in a cow.
Boileau, Mélanie J; Jann, Henry W; Confer, Anthony W
2009-04-01
A 10-year-old Longhorn cow pregnant with a valuable fetus was evaluated because of progressive inspiratory dyspnea of 6 weeks' duration. Physical examination findings were consistent with upper respiratory tract obstruction. A large pedunculated soft tissue mass was evident in the mid-dorsal aspect of the pharynx during palpation and endoscopic examination. Results of microscopic examination of transendoscopic fine-needle aspirates and a biopsy specimen were suggestive of a bacterial granuloma. Transtracheal intubation was performed, and the mass was excised with a chain écraseur. Results of histologic examination were consistent with a diagnosis of actinobacillosis. The owner reported that the cow was doing well without any recurrence of respiratory distress 8 months after surgery. Findings suggested that pharyngeal granuloma resulting from actinobacillosis should be included in the differential diagnoses when examining mature cattle with upper respiratory tract obstruction and that a chain écraseur may be useful for excising soft tissue pharyngeal masses in cattle.

Endoscopic balloon dilatation (EBD) is an effective therapy for caustic-induced gastric outlet obstruction (GOO). Gaining access to the stricture site is the most important step. It is sometimes difficult to negotiate a balloon through the stricture with a front-viewing endoscope due to deformed anatomy of stomach. To overcome this technical difficulty, a side-viewing endoscope can be used. There is limited data regarding the use of side-viewing endoscopes in EBD. We here report on the short-term efficacy and safety of EBD in caustic-induced GOO. In technically difficult cases, a side-viewing endoscope was used for EBD and its efficacy and safety were assessed. The study included 25 patients with caustic-induced GOO. Patients underwent EBD using a through-the-scope balloon. Initial balloon dilatation was performed with a front-viewing endoscope. A side-viewing endoscope was used where negotiation across the stricture failed with a front-viewing endoscope. Dilatation was started at 8 mm diameter and was performed at 1-week intervals. The end point of dilatation was 15 mm diameter. In 18 patients successful balloon dilatation was possible with a front-viewing endoscope. A side-viewing endoscope was used in six patients as negotiation across the stricture was not possible with a front-viewing endoscope. In all six patients negotiation across the stricture followed by successful dilatation was successful with a side-viewing endoscope. Of the 25 patients included in this study, 24 (96%) achieved procedural success (18 with a front-viewing endoscope and 6 with a side-viewing endoscope) in 3-9 sessions. Our results show that EBD is a safe and effective option for caustic-induced GOO and in difficult cases a side-viewing endoscope can be used to achieve technical success.

To investigate whether omeprazole has improved morbidity-mortality among patients with upper gastrointestinal bleeding of non-variceal origin in comparison with ranitidine. Prospective, randomized and open study. We study 519 consecutive patients admitted to our Service between June 1991 and January 1993 for upper gastrointestinal bleeding of peptic origin, dividing the patients into two randomized groups that were homogeneous in terms of age, sex, previous history of gastric disease and upper gastrointestinal bleeding, intake of non-steroidal antiinflammatory drugs, and the severity of bleeding on admittance. Thus, Group A consisted of 252 patients treated immediately upon arrival at the emergency ward with 50 mg intravenous ranitidine, followed by a further 50 mg every 6 hours. Group B in turn consisted of 267 patients initially given a bolus dose of 80 mg omeprazole intravenously, followed by an additional 40 mg every 8 hours for 48 hours. Forty mg were subsequently administered every 12 hours until hospital discharge. Endoscopy was performed in all cases within the first 24 hours following admittance, those patients with active upper gastrointestinal bleeding resulted from Forrest-type ulcer of subjected to endoscopic sclerotherapy were excluded. Duodenal ulcer was the most common cause of bleeding, followed by gastric ulcer and acute lesions of the mucosa. Emphasis should be placed on the high incidence of previous non-steroidal antiinflammatory drug intake in our series (54.5%). We encountered no statistically significant differences between the two groups on comparing bleeding stigmata, transfusion requirements, recurrences, emergency surgery, the duration of hospital stay, and mortality. Both drugs were found to possess a similar efficacy in treating upper gastrointestinal bleeding of peptic origin.

This is a retrospective analysis of interventional embolisation performed with catheter angiography in 29 patients with upper gastrointestinal bleeding in the setting of a secondary care hospital. From April 2007 to February 2013, 29 patients with upper gastrointestinal bleeding underwent endovascular diagnostics and treatment. The diagnosis was established by endoscopy, computed tomography or clinically based on a significant decrease in hemoglobin. Transcatheter arterial embolisation was performed with coils, liquid embolic agents, and particles. The technical and clinical outcomes were assessed by postinterventional endoscopy, hemoglobin concentrations, number of necessary transfusions, or surgical interventions, as well as by post-interventional mortality within 28 days after the procedure. Selective angiographic embolisation in upper gastrointestinal bleeding was primarily successful technically and clinically in 22 of 29 patients. In 4/29 cases an angiographic reintervention was performed, which was successful in 3 cases. In 3 cases of primarily technically unsuccessful procedures reintervention was not attempted. No catheterisation-related complications were recorded. Peri-interventional mortality was 31%, but only 2 of these patients died due to uncontrolled massive bleeding, whereas the lethal outcome in the other 7 patients was due to their underlying diseases. Transcatheter arterial embolisation is an effective and rapid method in the management of upper gastrointestinal bleeding. Radiological endovascular interventions may considerably contribute to reduced mortality in GI bleeding by avoiding a potential surgical procedure following unsuccessful endoscopic treatment. The study underlines the importance of the combination of interventional endoscopy with interventional radiology in secondary care hospitals for patient outcome in complex and complicated upper gastrointestinal bleeding situations. © Georg Thieme Verlag KG Stuttgart · New York.

Acute bleeding from the upper gastrointestinal system is a medical emergency which is followed by high mortality rate, ranging from 6 to 15% in spite of modern diagnostic methods and treatment. Bleeding from the upper gastrointestinal system may be caused by gastrointestinal stromal tumors of the stomach, which are mainly characterized by occult bleeding, while profuse bleeding rarely occurs accompanied by hemorrhagic shock. Gastrointestinal stromal tumors of stomach are the most common mesenchimal tumors of the gastrointestinal tract. In our study we showed a 60-year-old female patient with profuse bleeding from the stomach and the clinical picture of severe hemorrhagic shock, caused by gastrointestinal stromal tumor. An ovoid junction, raised towards the lumen, covered with ulcerated mucosa in several places and followed by massive arterial bleeding was found intraoperatively, after the performed gastrotomy. Histopathological examination with immunohistochemical analysis confirmed that this was a gastrointestinal stromal tumor of the stomach. Acute bleeding from the digestive system is a sudden and serious condition of the body. Urgent esophagogastroduodenoscopy is a sensitive and specific diagnostic and therapeutic method of choice. Massive bleeding from the upper gastrointestinal tract is very rarely caused by gastrointestinal stromal tumors, whose clinical picture is very heterogeneous and depends on tumor size and location. Abundant bleeding from the tumor is an indication for urgent surgical intervention. According to the literature massive hemorrhage of the upper digestive system can rarely be caused by gastrointestinal stromal tumor of the stomach. It is shown that abundant hemorrhage of the upper digestive tract can be caused with gastric gastrointestinal stromal tumor. Surgical resection is the main form of treatment of gastrointestinal stromal tumors of the digestive system and bleeding from these tumors caused by failure of endoscopic hemostasis.

Multiple scoring systems have been developed to predict outcomes in patients with upper gastrointestinal bleeding. We determined how well these and a newly established scoring model predict the need for therapeutic intervention, excluding transfusion, in Japanese patients with upper gastrointestinal bleeding. We reviewed data from 212 consecutive patients with upper gastrointestinal bleeding. Patients requiring endoscopic intervention, operation, or interventional radiology were allocated to the therapeutic intervention group. Firstly, we compared areas under the curve for the Glasgow-Blatchford, Clinical Rockall, and AIMS65 scores. Secondly, the scores and factors likely associated with upper gastrointestinal bleeding were analyzed with a logistic regression analysis to form a new scoring model. Thirdly, the new model and the existing model were investigated to evaluate their usefulness. Therapeutic intervention was required in 109 patients (51.4%). The Glasgow-Blatchford score was superior to both the Clinical Rockall and AIMS65 scores for predicting therapeutic intervention need (area under the curve, 0.75 [95% confidence interval, 0.69-0.81] vs 0.53 [0.46-0.61] and 0.52 [0.44-0.60], respectively). Multivariate logistic regression analysis retained seven significant predictors in the model: systolic blood pressure <100 mmHg, syncope, hematemesis, hemoglobin <10 g/dL, blood urea nitrogen ≥22.4 mg/dL, estimated glomerular filtration rate ≤ 60 mL/min per 1.73 m 2 , and antiplatelet medication. Based on these variables, we established a new scoring model with superior discrimination to those of existing scoring systems (area under the curve, 0.85 [0.80-0.90]). We developed a superior scoring model for identifying therapeutic intervention need in Japanese patients with upper gastrointestinal bleeding. © 2016 Japan Gastroenterological Endoscopy Society.

To compare the efficacy of proton pump inhibitors (PPIs) with rebamipide versus PPIs alone for the treatment of ulcers after endoscopic submucosal dissection (ESD). PubMed, Web of Science, Medline, Embase, the Cochrane Central Register of Controlled Trials and China Naitonal Knowledge Infrastructure were searched up to the end of October 2013 in order to identify all randomized controlled trials reporting the effects of PPIs plus rebamipide on healing ulcers after ESD. The outcome measurement was complete ulcer healing. A total of six studies involving 724 patients were included. The pooled data suggested a significantly higher rate of ulcer healing after endoscopic therapy among patients treated with PPIs plus rebamipide than among those treated with PPIs alone [odds ratio (OR)=2.40, 95% confidence interval (CI): 1.68-3.44]. The subgroup analysis showed PPI plus rebamipide therapy to be more effective in healing ESD-induced ulcers than treatment with PPIs alone after both four (OR=2.22, 95%CI: 1.53-3.24) and eight weeks of treatment (OR=3.19, 95%CI: 1.22-8.31). In addition, the combination therapy was found to be significantly more effective than the use of PPIs alone for all ESD ulcers greater than 20 mm in size (OR=4.77, 95%CI: 2.22-10.26). There were no significant differences between the treatment groups with regard to ulcer location (low, middle or upper stomach) or the presence of absence of H. pylori infection. No serious adverse events were observed in either group. The results of this meta-analysis suggest that treatment with PPIs plus rebamipide is superior to PPI monotherapy for healing ESD-induced ulcers over four weeks, particularly large ulcers. However, more well-designed trials are needed to confirm these findings.

Gastrointestinal (GI) involvement in Behçet's disease (BD) mainly appears in mucosa and affects 5-40% of patients, however the effects of the disease on lower esophageal sphincter (LES) pressure and esophageal contractions are not well known. The aims of this study were to evaluate esophageal motor function and to identify whether there was any specific motility pattern for patients with BD who had upper GI symptoms without endoscopic abnormality. 25 patients with BD, with a mean age of 43.1 (range 20-66) years, were admitted to our clinic whose main complaints were dyspeptic such as reflux, epigastric pain, vomiting and bloating. 25 healthy and age-matched individuals were also included in the study as controls. After one night fasting, LES pressure and esophageal contractions were measured. Esophageal motor abnormalities were detected in 16% (4/25) of these patients with manometric studies (non-specific esophageal motor disorder in 1, esophageal hypomotility in 2, and LES hypotension in 1 patient); 16% (4/25) of these patients had endoscopic findings and overall 32% (8/25) of the cases showed esophageal pathology. All cases with esophageal motor abnormalities were suffering from reflux and endoscopy showed grade B esophagitis in 2 of these cases. Median LES pressure and LES relaxation were significantly lower in patients with BD compared to the control group (16.8 +/- 10.5 vs. 20.4 +/- 6.1, p = 0.02, and 92.1 +/- 10.1 vs. 96.4 +/- 4.5, p = 0.03 respectively). Esophageal involvement in BD is significantly high. We propose manometric studies are necessary to evaluate esophageal manifestations in BD patients with esophageal symptoms even without endoscopic findings.

Atrophic gastritis can be classified according to characteristic mucosal patterns observed by Blue LASER Imaging (BLI) in a medium-range to distant view. To facilitate the endoscopic diagnosis of Helicobacter pylori (HP)-related gastritis, we investigated whether atrophic mucosal patterns correlated with HP infection based on the image interpretations of three endoscopists blinded to clinical features. This study included 441 patients diagnosed as having atrophic gastritis by upper gastrointestinal endoscopy at Nishikawa Gastrointestinal Clinic between April 1, 2015 and March 31, 2016. The presence/absence of HP infection was not taken into consideration. Endoscopy was performed using a Fujifilm EG-L580NW scope. Atrophic mucosal patterns observed by BLI were classified into Spotty, Cracked and Mottled. Image interpretation results were that 89, 122 and 228 patients had the Spotty, Cracked and Mottled patterns, respectively, and 2 patients an undetermined pattern. Further analyses were performed on 439 patients, excluding the 2 with undetermined patterns. The numbers of patients testing negative/positive for HP infection in the Spotty, Cracked and Mottled pattern groups were 12/77, 105/17, and 138/90, respectively. The specificity, positive predictive value and positive likelihood ratio for endoscopic diagnosis with positive HP infection based on the Spotty pattern were 95.3%, 86.5% and 8.9, respectively. In all patients with the Spotty pattern before HP eradication, the Cracked pattern was observed on subsequent post-eradication endoscopy. The Spotty pattern may represent the presence of HP infection, the Cracked pattern, a post-inflammatory change as seen after HP eradication, and the Mottled pattern, intestinal metaplasia.

Hyaluronic acid (HA) is involved in modulating inflammatory airway processes and mucociliary clearance. Some studies have tested the effectiveness of the topical administration of HA in patients with upper airway diseases with positive preliminary results. A prospective, single-blind, 1:1 randomised controlled study was performed to assess the efficacy and safety of the daily topical administration of 9 mg of sodium hyaluronate in 3 mL of a 0.9 % sodium saline solution on the basis of endoscopic and clinical parameters in children with chronic adenoiditis associated with recurrent acute otitis media and otitis media with effusion; age- and gender-matched children receiving normal 0.9 % sodium chloride saline solution were used as controls. Analysis was based on 103 (mean age 63.3 ± 18.2 months; 52 males, 50.5 %) children: 54 in the study group and 49 in the control group. A statistically significant reduction in the mean number of all acute otitis media episodes (AOME) (mean reduction 0.8 ± 0.4 per month; p value 0.05) and AOME without tympanic membrane perforation (mean reduction 0.6 ± 0.3 per month; p value 0.04) after recruitment was documented only in the study group. HA significantly improved all the endoscopic outcomes (p values ranging between 0.05 and <0.01) but one. Nasal washing with saline solution was effective on only three of them (p values ranging between 0.03 and <0.01). No untoward effects were documented. Our results confirm the safety and document the positive effect of topically administered HA solution on children with chronic adenoiditis associated with middle ear disease.

Although nonsteroidal anti-inflammatory drugs (NSAIDs) are widely prescribed globally, their chronic use increases the risk of upper gastrointestinal (GI) damage. Cyclooxygenase-2-selective NSAIDs are considered to reduce this risk. Current guidelines in Japan recommend loxoprofen sodium (loxoprofen), a pro-drug in the propionic acid class of nonselective NSAIDs, as first-line therapy in rheumatoid arthritis. To confirm the superiority of celecoxib, a cyclooxygenase-2-selective NSAID, to loxoprofen in the incidence of gastroduodenal (GD) endoscopic ulcers. A randomised, multicentre, placebo-controlled, double-blind, phase IV clinical trial in healthy Japanese volunteers [mean age 57.5 (range: 40-74) years; >70% female], stratified by Helicobacter pylori status at screening (~40% positive) and randomised 2:2:1 to receive celecoxib 100 mg b.d., loxoprofen 60 mg t.d.s. or placebo. Primary end point was incidence of any GD endoscopic ulcers after 2 weeks of treatment. Of 190 randomised subjects, 189 received at least one dose of celecoxib (n = 76), loxoprofen (n = 76), or placebo (n = 37). Incidence of GD ulcers was 1.4%, 27.6% and 2.7% in the celecoxib, loxoprofen and placebo groups respectively (P < 0.0001 in favour of the celecoxib group); incidence of adverse events (AEs) was 34.2%, 51.3% and 21.6% in the celecoxib, loxoprofen and placebo groups respectively. No serious or severe AEs were reported. Celecoxib 100 mg b.d. was superior to loxoprofen 60 mg t.d.s. regarding the incidence of gastro-duodenal endoscopic ulcers over 2 weeks. Celecoxib was well tolerated and no major safety concerns were observed. © 2012 Blackwell Publishing Ltd.

Objective: To evaluate the usefullness of flexible esophagoscopy and chromoendoscopy with Lugol's solution in the detection of synchronous esophageal neoplasm in patients with hypopharyngeal squamous cell carcinoma (HSCC). Methods: A retrospective review of 96 cases with HSCC that received surgical treatment from March 2016 to March 2017 was accomplished. In these patients, the site of origin were pyriform sinus ( n =75), posterior pharyngeal wall ( n =11) and postcricoid ( n =10). Esophagoscopy was prospectively performed on all patients before treatment for HSCC. All patients underwent conventional white-light endoscopic examination with Lugol chromoendoscopy and narrow band image. Suspicious areas of narrow band image or Lugol-voiding lesions were observed and biopsied. The treatment strategy of primary HSCC was modified according to the presence of synchronous esophageal squamous cell neoplasms by a multidisciplinary approach. Results: Ninety-six patients were enrolled (age ranging from 37-80 years). All patients did not have previous treatment.Histopathological analysis revealed middle to high-grade dysplasia in 5 cases, Tis cancer in 5 cases, cancer in 16 cases and inflammation or normal findings in the others. Four cases were treated with endoscopic submucosal dissection before hypopharygeal surgery, 3 cases with lower esophageal cancers were treated with gastric pull-up combined with free jejunal flap after total circumferential pharyngolaryngectomy (TCPL) and certical esophagectomy, and 14 cases were treated with TCPL, total esophagectomy and gastric pull-up. Conclusions: Esophagoscopy is a feasible and justified procedure in HSCC cases as it enhances the detection of premalignant lesion or second primary cancer. Routine esophagoscopy for detecting synchronous second primary tumor should be recommended for patients with HSCC. The treatment strategy for primary HSCC is modified according to the presence of synchronous second primary tumor.

To determine the association between functional dyspepsia and the severity of depression. Cross-sectional study. Department of Medicine, King Edward Medical University/Mayo Hospital, Lahore, from September 2012 till January 2013. After taking informed written consent, patients with symptoms of dyspepsia fulfilling the Rome III criteria were included in the study. All patients were evaluated for depression, using Hamilton depression rating scale (HDRS). Upper gastrointestinal endoscopy was done. Fischers' exact test and independent t-test were used for determining significance of association. One hundred and one patients with mean age of 35.81 (±14.81) years and male to female ratio of 1.41:1 (54/47) were included. Predominant symptoms were early satiety (72.3%), epigastric pain (65.3%), bloating (49.5%), postprandial fullness (40.6%), and regurgitation (40.6%). Alarm symptoms were positive in 44 (43.6%) patients. Dyspepsia were classified as epigastric pain syndrome (EPS, 69.3%), and postprandial distress syndrome (PDS, 30.7%). Significantly more females had PDS (p=0.04), with positive endoscopic findings in EPS (p=0.03). Positive endoscopic findings noted were esophagitis in 21.8%, and gastritis in 48.5% patients. All patients except one had depression, mild in 22.8%, moderate in 33.7%, severe in 31.7%, and very severe in 10.9% patients. Severe depression was seen in 32 (45.7%) patients with EPS and PDS; whereas very severe depression was in 11 (15.7%) patients of EPS, while 11 (35.4%) patients of PDS had severe depression but the difference was not significant. Functional dyspepsia is associated with depression, while positive endoscopic findings are more likely in patients with EPS. Very severe depression was only seen with epigastric pain syndrome.
