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. 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). 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.

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.

Although propofol-based sedation can be used during emergency endoscopy for upper gastrointestinal bleeding (UGIB), there is a potential risk of sedation-related adverse events, especially in patients with variceal bleeding. We compared adverse events related to propofol-based sedation during emergency endoscopy between patients with non-variceal and variceal bleeding. Clinical records of patients who underwent emergency endoscopy for UGIB under sedation were reviewed. Adverse events, including shock, hypoxia, and paradoxical reaction, were compared between the non-variceal and variceal bleeding groups. Of 703 endoscopies, 539 and 164 were performed for non-variceal and variceal bleeding, respectively. Shock was more common in patients with variceal bleeding compared to those with non-variceal bleeding (12.2 vs. 3.5%, P < 0.001). All patients except one recovered from shock after normal saline hydration, and emergency endoscopy could be finished without interruption in most cases. The incidence of hypoxia and paradoxical reaction did not differ based on the source of bleeding (non-variceal bleeding vs. variceal bleeding: hypoxia, 3.5 vs. 1.8%, P = 0.275; paradoxical reaction interfering with the procedure, 4.1 vs. 5.5%, P = 0.442). Although shock was more common in patients with variceal bleeding compared to those with non-variceal bleeding, most cases could be controlled without procedure interruption. Paradoxical reaction, rather than shock or hypoxia, was the most common cause of procedure interruption in patients with variceal bleeding, but the rate did not differ between patients with non-variceal and variceal bleeding.

Laundry detergent pod ingestions: is there a need for endoscopy?

Laundry detergent pod (LDP) exposures in children have resulted in several referrals to the emergency department. Signs and symptoms can include gastrointestinal symptoms (vomiting, drooling), neurological symptoms (depressed sensorium), or metabolic changes (lactic acidosis). There is limited literature on esophageal injury following LDP ingestions. We reviewed three cases of pediatric LDP ingestions that underwent an upper endoscopy in a tertiary care pediatric hospital. All of our patients were younger than 3 years old. The upper endoscopies revealed superficial esophageal erosions in two patients and erythema in the other. None of the patients had oral burns. Two of them developed swallowing dysfunction. Follow-up upper GI studies were normal. Our three patients ingested laundry detergent pods and all of them developed some degree of esophageal injury despite the absence of oral erythema, ulcers, or swelling. A review of literature suggests LDP exposures are more severe than non-pod detergents. Reasons as to why this may be remain unclear, although investigation into the ingredients and mode of delivery may help us to better understand. In a literature review, no esophageal strictures have been reported after LDP ingestion. We reviewed esophageal injury classification systems in an attempt to predict who may be at greatest risk for stricture based on initial findings. Our case series demonstrates it is hard to predict esophageal injury based on signs and symptoms. Based on a literature review, long-term esophageal stricture is unlikely, but if gastrointestinal symptoms persist, it is reasonable to evaluate with an upper endoscopy. Larger studies are needed.

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.

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.

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.

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.

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.

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.

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.

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.

Gastro-oesophageal reflux disease (GORD) is the pathological reflux of gastric contents into the oesophagus. The oesophagus and the upper respiratory tract have a common origin from the foregut. There is increasing evidence for multiple associations of GORD with the upper respiratory tract. To study the presence of and association of upper respiratory symptoms (URS) with GORD. Seventy adults scoring ≥12.5 on a previously validated GORD symptom score (GORD patients) and 70 healthy controls who had infrequent GORD symptoms or no upper gastro-intestinal complaints completed a pre-tested URS questionnaire on the frequency of 14 URS in 5 categories (laryngeal, nasal, pharyngeal, sinusal and aural). All GORD patients underwent upper gastro-intestinal endoscopy. The calculated URS score was correlated against the GORD symptom score and endoscopy findings. URS scores and individual symptom scores were higher in GORD patients compared to controls (mean ± SE, 4.7 ± 4.0; 1.9 ± 2.3). Individuals with higher GORD symptom scores reported more frequent URS. Pharyngeal symptoms had the highest correlation with the GORD symptom score (r=0.507, p<0.001). The presence of oeso-phagitis did not seem to influence the frequency of reporting URS. Upper respiratory symptoms are common in individuals with GORD symptoms though there appears to be no association with oesophageal mucosal damage.

Raman spectroscopy is a vibrational analytic technique sensitive to the changes in biomolecular composition and conformations occurring in tissue. With our most recent development of near-infrared (NIR) Raman endoscopy integrated with diagnostic algorithms, in vivo real-time Raman diagnostics has been realized under multimodal wide-field imaging (i.e., white- light reflectance (WLR), narrow-band imaging (NBI), autofluorescence imaging (AFI)) modalities. A selection of 177 patients who previously underwent Raman endoscopy (n=2510 spectra) was used to render two robust models based on partial least squares - discriminant analysis (PLS-DA) for esophageal and gastric cancer diagnosis. The Raman endoscopy technique was validated prospectively on 4 new gastric and esophageal patients for in vivo tissue diagnosis. The Raman endoscopic technique could identify esophageal cancer in vivo with a sensitivity of 88.9% (8/9) and specificity of 100.0% (11/11) and gastric cancers with a sensitivity of 77.8% (14/18) and specificity of 100.0% (13/13). This study realizes for the first time the image-guided Raman endoscopy for real-time in vivo diagnosis of malignancies in the esophagus and gastric at the biomolecular level.

The objectives of this study were to define the utility of esophagogastroduodenoscopy in the diagnosis and management of patients presenting with dysphagia and to determine the relative incidence of the various causes of dysphagia in Sudan. This is a prospective, cross-sectional, descriptive, hospital-based study carried out at the endoscopy unit of Soba University Hospital, Khartoum, Sudan. All patients complaining of dysphagia underwent upper gastrointestinal endoscopy with therapeutic intervention when necessary. A total of 114 patients were enrolled in the study, with a mean age of 47 years SD +/- 19 and a male to female ratio of 1 : 1.04. A benign condition was diagnosed in 56% of the cases; this included esophageal strictures in 21% of the cases and achalasia in 14%. Malignant causes were mainly due to esophageal cancer (40.4%) and cancer of the stomach cardia (3.5%). Therapeutic intervention was attempted in 83% of the cases. Risk factors predictive of a malignant etiology were age over 40 years (P < 0.000), dysphagia lasting between 1 month and 1 year (P < 0.000), and weight loss (P < 0.000). A barium study was performed in 35 cases (31%) prior to endoscopic examination and proved to be inaccurate in three cases (8.6%). Upper gastrointestinal endoscopy in our African setting is an accurate and useful investigation in the diagnosis and management of patients presenting with dysphagia. Patients over the age of 40 years presenting with dysphagia and weight loss are more likely to have a neoplastic disease and should be referred for urgent endoscopy.

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.

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.

After the introduction of flexible fiber optic endoscopy to pediatric gastroenterology in the 1970s, upper gastrointestinal (UGI) endoscopy can be performed for the diagnosis and treatment of all age groups of children. We review indications, contraindications, preparation of patients for the procedure, and details of diagnostic and therapeutic UGI endoscopy used in pediatric surgery. We also discuss potential complications of endoscopy. PMID:26566483

To investigate the early upper gastrointestinal endoscopy (endoscopy) significantly reduces mortality resulting from upper gastrointestinal (GI) bleeding. Upper GI bleeding was defined as 1a, 1b, 2a, and 2b according to the Forrest classification. The hemoglobin (Hb), and C-reactive protein (CRP) were examined at around the day of endoscopy and 3 mo prior to endoscopy. The rate of change was calculated as follows: (the result of blood examination on the day of endoscopy - the results of blood examination 3 mo prior to endoscopy)/(results of blood examination 3 mo prior to endoscopy). Receiver operating characteristic curves were created to determine threshold values. Seventy-nine men and 77 women were enrolled. There were 17 patients with upper GI bleeding: 12 with a gastric ulcer, 3 with a duodenal ulcer, 1 with an acute gastric mucosal lesion, and 1 with gastric cancer. The area under the curve (AUC), threshold, sensitivity, and specificity of Hb around the day of endoscopy were 0.902, 11.7 g/dL, 94.1%, and 77.1%, respectively, while those of CRP were 0.722, 0.5 mg/dL, 70.5%, and 73%, respectively. The AUC, threshold, sensitivity, and specificity of the rate of change of Hb were 0.851, -21.3%, 76.4%, and 82.6%, respectively, while those of CRP were 0.901, 100%, 100%, and 82.5%, respectively. Predictors for upper GI bleeding were Hb < 11.7 g/dL, reduction rate in the Hb > 21.3% and an increase in the CRP > 100%, 3 mo before endoscopy.

Upper gastrointestinal endoscopy (UGI-ES) and double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) are two major image-based methods to diagnose atrophic gastritis, which is mostly induced by Helicobacter pylori infection. However, there have been few studies directly comparing them. Atrophic gastritis was evaluated using the data of 962 healthy subjects who underwent UGI-ES and UGI-XR within 1 year. Based on UGI-ES and UGI-XR, 602 subjects did not have atrophic gastritis and 254 subjects did have it. Considering UGI-ES-based atrophic gastritis as the standard, sensitivity and specificity of UGI-XR-based atrophic gastritis were 92.0 % (254/276) and 92.8 % (602/649), respectively. The seven-grade Kimura-Takemoto classification of UGI-ES-based atrophic gastritis showed a strong and significant association with the four-grade UGI-XR-based atrophic gastritis. Sensitivity and specificity of serum anti-Helicobacter pylori IgG to detect UGI-ES/UGI-XR-based atrophic gastritis were 89.4 % (227/254) and 99.8 % (601/602), indicating that atrophic gastritis can be overlooked according to serum anti-Helicobacter pylori IgG alone.

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.

Gastric carcinoma is derived from epithelial cells in the gastric mucosa. We reported an extremely rare case of submucosal gastric carcinoma originating from the heterotopic submucosal gastric gland (HSG) that was safely diagnosed by laparoscopy and endoscopy cooperative surgery (LECS). A 66-year-old man underwent gastrointestinal endoscopy, which detected a submucosal tumor (SMT) of 1.5 cm in diameter on the lesser-anterior wall of the upper gastric body. The tumor could not be diagnosed histologically, even by endoscopic ultrasound-guided fine-needle aspiration biopsy. Local resection by LECS was performed to confirm a diagnosis. Pathologically, the tumor was an intra-submucosal well differentiated adenocarcinoma invading 5000 μm into the submucosal layer. The resected tumor had negative lateral and vertical margins. Based on the Japanese treatment guidelines, additional laparoscopic proximal gastrectomy was curatively performed. LECS is a less invasive and safer approach for the diagnosis of SMT, even in submucosal gastric carcinoma originating from the HSG. PMID:26306144

BACKGROUND Aspartate aminotransferase-to-platelet ratio index (APRI), aspartate aminotransferase-to-alanine aminotransferase ratio (AAR), FIB-4, fibrosis index (FI), and King scores might be alternatives to the use of upper gastrointestinal endoscopy for the diagnosis of esophageal varices (EVs) in liver cirrhosis. This study aimed to evaluate their diagnostic accuracy in predicting the presence and severity of EVs in liver cirrhosis. MATERIAL AND METHODS All patients who were consecutively admitted to our hospital and underwent upper gastrointestinal endoscopy between January 2012 and June 2014 were eligible for this retrospective study. Areas under curve (AUCs) were calculated. Subgroup analyses were performed according to the history of upper gastrointestinal bleeding (UGIB) and splenectomy. RESULTS A total of 650 patients with liver cirrhosis were included, and 81.4% of them had moderate-severe EVs. In the overall analysis, the AUCs of these non-invasive scores for predicting moderate-severe EVs and presence of any EVs were 0.506-0.6 and 0.539-0.612, respectively. In the subgroup analysis of patients without UGIB, their AUCs for predicting moderate-severe varices and presence of any EVs were 0.601-0.664 and 0.596-0.662, respectively. In the subgroup analysis of patients without UGIB or splenectomy, their AUCs for predicting moderate-severe varices and presence of any EVs were 0.627-0.69 and 0.607-0.692, respectively. CONCLUSIONS APRI, AAR, FIB-4, FI, and King scores had modest diagnostic accuracy of EVs in liver cirrhosis. They might not be able to replace the utility of upper gastrointestinal endoscopy for the diagnosis of EVs in liver cirrhosis.

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.

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.

"Leopard skin sign": the use of narrow-band imaging with magnification endoscopy in celiac disease.

Celiac Disease (CD) is an immune reaction to gluten containing foods such as rye, wheat and barley. This condition affects individuals with a genetic predisposition; it targets the small bowel and may cause symptoms including diarrhea, malabsorption, weight loss, abdominal pain and bloating. The diagnosis is made by serologic testing of celiac-specific antibodies and confirmed by histology. Certain endoscopic characteristics, such as scalloping, reduction in the number of folds, mosaic-pattern mucosa or nodular mucosa, are suggestive of CD and can be visualized under white light endoscopy. Due to its low sensitivity, endoscopy alone is not recommended to diagnose CD; however, enhanced visual identification of suspected mucosal abnormalities through the use of new technologies, such as narrow band imaging with magnification (NBI-ME), could assist in targeting biopsies and thereby increasing the sensitivity of endoscopy. This is a case series of seven patients with serologic and histologic diagnoses of CD who underwent upper endoscopies with NBI-ME imaging technology as part of their CD evaluation. By employing this imaging technology, we could identify patchy atrophy sites in a mosaic pattern, with flattened villi and alteration of the central capillaries of the duodenal mucosa. We refer to this epithelial pattern as "Leopard Skin Sign". Since epithelial lesions are easily seen using NBI-ME, we found it beneficial for identifying and targeting biopsy sites. Larger prospective studies are warranted to confirm our findings.

Factitious disorder: a rare cause of haematemesis.

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.

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.

Upper gastrointestinal bleeding (UGIB) remains a significant cause of morbidity and mortality with mortality rates as high as 14%. This document addresses the indications for imaging UGIB that is nonvariceal and unrelated to portal hypertension. The four variants are derived with respect to upper endoscopy. For the first three, it is presumed that upper endoscopy has been performed, with three potential initial outcomes: endoscopy reveals arterial bleeding source, endoscopy confirms UGIB without a clear source, and negative endoscopy. The fourth variant, "postsurgical and traumatic causes of UGIB; endoscopy contraindicated" is considered separately because upper endoscopy is not performed. When endoscopy identifies the presence and location of bleeding but bleeding cannot be controlled endoscopically, catheter-based arteriography with treatment is an appropriate next study. CT angiography (CTA) is comparable with angiography as a diagnostic next step. If endoscopy demonstrates a bleed but the endoscopist cannot identify the bleeding source, angiography or CTA can be typically performed and both are considered appropriate. In the event of an obscure UGIB, angiography and CTA have been shown to be equivalent in identifying the bleeding source; CT enterography may be an alternative to CTA to find an intermittent bleeding source. In the postoperative or traumatic setting when endoscopy is contraindicated, primary angiography, CTA, and CT with intravenous contrast are considered appropriate. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. Copyright © 2017 American College of Radiology.

Bidirectional endoscopy (BE) is often used to assess patients for the reason of anemia or to screen asymptomatic population for malignancy. Limited clinical data favors to perform first the upper gastrointestinal system endoscopy, but its effect to the duration of colonoscopy is yet to be determined. The aim of this retrospective study is to evaluate the effect of upper gastrointestinal system endoscopy on the time to achieve cecal intubation during colonoscopy in patients undergoing BE. Patients of four endoscopists at similar experience levels were retrospectively identified and categorized into the upper gastrointestinal system endoscopy before colonoscopy group (group 1) or the colonoscopy only group (group 2). The demographics, clinical data and the time to achieve cecal intubation for each patient were analyzed. The mean time to achieve cecal intubation in the first group that included 319 cases was 8.4 ± 0.93 minutes and the mean time in the second group that included 1672 cases was 8.56 ± 1.16 minutes. There was no statistically significant difference between the groups. There was also no significant difference between the Group 1 and Group 2 when compared according to which of the four endoscopists performed the procedures. Performing the upper gastrointestinal system endoscopy prior to colonoscopy did not affect the time to achieve cecal intubation. Considering that performing the upper gastrointestinal system endoscopy prior to the colonoscopy is more advantageous in terms of patient comfort and analgesic requirement, beginning to BE with it seems more favorable.

To assess changes in practice and outcome in acute upper gastrointestinal haemorrhage following the feedback of data, the reemphasis of national guidelines, and specific recommendations following an initial survey. A prospective, multicentre, audit cycle. Forty five hospitals from three health regions participated in two phases of the audit cycle. Phase I: 2332 patients with acute upper gastrointestinal haemorrhage; phase II: 1625 patients with upper gastrointestinal haemorrhage. Patients were evaluated with respect to management (with reference to the recommendations in the national guidelines), mortality, and length of hospital stay. Following the distribution of data from the first phase of the National Audit and the formulation of specific recommendations for improving practice, the proportion of hospitals with local guidelines or protocols for the management of upper gastrointestinal haemorrhage rose from 71% (32/45) to 91% (41/45); 12 of the 32 hospitals with guidelines during the first phase revised their guidelines following the initial survey. There was a small but significant increase in the proportion of all patients who underwent endoscopy (from 81% to 86%), the proportion who underwent endoscopy within 24 hours of admission (from 50% to 56%), and the use of central venous pressure monitoring in patients with organ failure requiring blood transfusion or those with profound shock (from 30% to 43%). There was, however, no change in the use of high dependency beds or joint medical/surgical management in high risk cases. There was no significant change in crude or risk standardised mortality (13.4% in the first phase and 14.4% in the second phase). Although many of the participating hospitals have made efforts to improve practice by producing or updating guidelines or protocols, there has been only a small demonstrable change in some areas of practice during the National Audit. The failure to detect any improvement in mortality may reflect this lack of change of practice, but may also reflect the fact that a large proportion of the deaths in this unselected study are not preventable; only a very large study could hope to demonstrate a significant change out of the context of a clinical trial.

The prevalence of Barrett's esophagus has been calculated at between 1.3 and 1.6%. There is little information with respect to this in Mexico. To determine the frequency and characteristics of Barrett's esophagus in patients that underwent endoscopy at a national referral center, within a 10-year time frame. The databases of the pathology and gastrointestinal endoscopy departments of the Instituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubirán" were analyzed, covering the period of January 2002 to December 2012. Patients with a histologic diagnosis of Barrett's esophagus were included. The variables of age, sex, the presence of dysplasia/esophageal adenocarcinoma, Barrett's esophagus length, and follow-up were analyzed. Of 43,639 upper gastrointestinal endoscopies performed, 420 revealed Barrett's esophagus, corresponding to a frequency of 9.6 patients for every 1,000 endoscopies. Of those patients, 66.9% (n=281) were men, mean patient age±SD was 57.2±15.3 years, 223 patients (53%) presented with long-segment Barrett's esophagus, and 197 (47%) with short-segment Barrett's esophagus. Dysplasia was not present in 339 patients (80.7%). Eighty-one (19.3%) patients had some grade of dysplasia or cancer: 48/420 (11.42%) presented with low-grade dysplasia, 20/420 (4.76%) with high-grade dysplasia, and 13/420 (3.1%) were diagnosed with esophageal cancer arising from Barrett's esophagus. Mean follow-up time was 5.6 years. The frequency of Barrett's esophagus was 9.6 cases for every 1,000 upper gastrointestinal endoscopies performed. Dysplasia was not documented in the majority of the patients with Barrett's esophagus and they had no histopathologic changes during follow-up. A total of 19.3% of the patients presented with dysplasia or cancer. Copyright © 2017 Asociación Mexicana de Gastroenterología. Publicado por Masson Doyma México S.A. All rights reserved.

Early upper gastrointestinal (UGI) cancer detection had led to organ-preserving endoscopic therapy. Endoscopy is a suitable method of early diagnosis of UGI malignancies. In Iran, exclusion of malignancy is the most important indication for endoscopy. This study is designed to see whether using alarm symptoms can predict the risk of cancer in patients. A total of 3414 patients referred to a tertiary gastrointestinal (GI) clinic in Isfahan, Iran, from 2009 to 2016 with dyspepsia, gastroesophageal reflux disease (GERD), and alarm symptoms, such as weight loss, dysphagia, GI bleeding, vomiting, positive familial history for cancer, and anorexia. Each patient had been underwent UGI endoscopy and patient data, including histology results, had been collected in the computer. We used logistic regression models to estimate the diagnostic accuracy of each alarm symptoms. A total of 3414 patients with alarm symptoms entered in this study, of whom 72 (2.1%) had an UGI malignancy. According to the logistic regression model, dysphagia ( P < 0.001) and weight loss ( P < 0.001) were found to be significant positive predictive factors for malignancy. Furthermore, males were in a significantly higher risk of developing UGI malignancy. Through receiver operating characteristic curve and the area under the curve (AUC) with adequate overall calibration and model fit measures, dysphagia and weight loss as a related cancer predictor had a high diagnostic accuracy (accuracy = 0. 72, AUC = 0. 881). Using a combination of age, alarm symptoms will lead to high positive predictive value for cancer. We recommend to do an early endoscopy for any patient with UGI symptoms and to take multiple biopsies from any rudeness or suspicious lesion, especially for male gender older than 50, dysphagia, or weight loss.

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.

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.

A rapid image-guided Raman endoscopy system integrated with on-line diagnostic scheme is developed for in vivo Raman tissue diagnosis (optical biopsy) in the upper GI during clinical gastrointestinal endoscopy under multimodal wide-field imaging guidance. The real-time Raman endoscopy technique was tested prospectively on new gastric patients (n=4) and could identify dysplasia in vivo with sensitivity of 81.5% (22/27) and specificity of 87.9% (29/33). This study realizes for the first time the novel image-guided Raman endoscopy as a screening tool for real-time, online diagnosis of gastric cancer and precancer in vivo at endoscopy.

- Previous evidence trying to assess the risk of celiac disease among dyspeptic patients has been inconclusive, showing in some cases notorious discrepancies. - To determine the prevalence of celiac disease in patients with dyspepsia compared to healthy controls without dyspepsia. - Adult patients under evaluation for dyspepsia were invited to participate. These patients were offered an upper gastrointestinal endoscopy with duodenal biopsies. On the other hand, asymptomatic adult volunteers who performed a preventive visit to their primary care physician were invited to participate and agreed to undertake an upper gastrointestinal endoscopy with duodenal biopsies as well. Those patients with histologic signs of villous atrophy were furtherly evaluated and serological tests were performed in order to determine celiac disease diagnosis. Celiac disease prevalence was compared between groups. - Overall, 320 patients with dyspepsia and 320 healthy controls were recruited. There were no significant differences in terms of gender or age between groups. Celiac disease diagnosis was made in 1.25% (4/320) of patients in the dyspepsia group versus 0.62% (2/320) in the control group. - Patients with dyspepsia who underwent routine duodenal biopsies did not show an increased risk for celiac disease when compared to healthy individuals.

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.

We herein report a rare case of a massive upper gastrointestinal (GI) bleeding, caused by high-grade diffuse B-cell lymphoma of the duodenum, secondary to immunoproliferative small intestinal disease (IPSID) and treated with an emergency partial pancreatoduodenectomy. A 42-year-old man was admitted to our hospital because of hematemesis. Upper GI endoscopy was unrevealing because of the copious bleeding. Initially, the patient underwent conservative treatment, thus resulting in the temporary cessation of the bleeding. Later, the hemorrhage massively relapsed. An urgent abdominal ultrasound raised the suspicion of a large, possibly bleeding, neoplasm of the duodenum, which was finally confirmed by abdominal computed tomography. The patient underwent an emergency laparotomy, during which a partial pancreatoduodenectomy was performed (Whipple procedure). Histologically, the tumor was a high-grade B-cell lymphoma of the duodenum. The nearby small intestinal mucosa was suggestive of IPSID. A massive upper GI hemorrhage from a high-grade B-cell non-Hodgkin lymphoma of the duodenum, which develops secondary to IPSID, is a very rare clinical demonstration of this disease. Our case is one of the few reports in the English literature, for which the Whipple procedure has been performed as a curative treatment.

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.

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.

Among the randomized controlled trials evaluating the effect of pharyngeal anaesthesia only some suggest benefit. Spray is irritating for some people and leaves bitter taste in the throat. We hypothesized that delivering the local anaesthetic as a sucking lozenge would benefit the patients in terms of decreasing anxiety and will improve procedure performance and patient tolerance. To determine whether benzocaine/tyrothricin sucking lozenges with conscious sedation is superior to conscious sedation alone, with respect to procedure performance and tolerance in patients undergoing upper endoscopy. One hundred and seventy-four adult patients undergoing upper endoscopy with conscious sedation completed the study. They were randomized to receive sucking lozenge containing benzocaine or placebo before the procedure. Patients were asked to rate prestudy anxiety, tolerance for topical pharyngeal anaesthesia, comfort during endoscopy, degree of difficulty of intubation, postprocedure throat discomfort and willingness to undergo subsequent examinations using a 10-cm visual analogue scale. Endoscopists were asked to estimate the ease of oesophageal intubation and procedure performance. No significant statistical differences regarding all the points studied were found between the groups. Topical pharyngeal anaesthesia with benzocaine/tyrothricin lozenges with conscious sedation has no advantages over conscious sedation alone in patients undergoing upper endoscopy.

This observational, retrospective cohort study assessed outcomes of the current management strategies for nonvariceal upper gastrointestinal bleeding in several European countries (Belgium, Greece, Italy, Norway, Portugal, Spain, and Turkey) (NCT00797641; ENERGIB). Turkey contributed 23 sites to this study. Adult patients (≥18 years old) consecutively admitted to hospital and who underwent endoscopy for overt non-variceal upper gastrointestinal bleeding (hematemesis, melena or hematochezia, with other clinical/laboratory evidence of acute upper GI blood loss) were included in the study. Data were collected from patient medical records regarding bleeding continuation, re-bleeding, pharmacological treatment, surgery, and mortality during a 30-day follow-up period. A total of 423 patients (67.4% men; mean age: 57.8 ± 18.9 years) were enrolled in the Turkish study centers, of whom 96.2% were admitted to hospital with acute non-variceal upper gastrointestinal bleeding. At admission, the most common symptom was melena (76.1%); 28.6% of patients were taking aspirin, 19.9% were on non-steroidal anti-inflammatory drugs, and 7.3% were on proton pump inhibitors. The most common diagnoses were duodenal (45.2%) and gastric (27.7%) ulcers and gastritis/gastric erosions (26.2%). Patients were most often managed in general medical wards (45.4%). A gastrointestinal team was in charge of treatment in 64.8% of cases. Therapeutic procedures were performed in 32.4% of patients during endoscopy. After the endoscopy, most patients (94.6%) received proton pump inhibitors. Mean (SD) hospital stay was 5.36 ± 4.91 days. The cumulative proportions of continued bleeding/re-bleeding, complications and mortality within 30 days of the non-variceal upper gastrointestinal bleeding episode were 9.0%, 5.7% and 2.8%, respectively. In the Turkish sub-group of patients, the significant risk factors for bleeding continuation or re-bleeding were age >65 years, presentation with hematemesis or shock/syncope, and the diagnosis of duodenal ulcer. The risk of clinical complications after non-variceal upper gastrointestinal bleeding was higher in female patients older than 65 years, in patients with comorbidities, and in patients presenting with shock/syncope, and also according to time to endoscopy. The use of aspirin, non-steroidal anti-inflammatory drugs or warfarin at baseline was negatively associated with the development of bleeding or clinical complications. The risk of death within 30 days after non-variceal upper gastrointestinal bleeding was significantly higher in patients older than 65 years and in those receiving transfusions other than intravenous fluid or red blood cells within 12 hours of presentation. According to the survey results, non-variceal upper gastrointestinal bleeding in Turkey varies from that in other European countries in a number of aspects. These differences could be associated with a younger population and Helicobacter pylori incidence. Despite the diminishing need for surgical intervention and mortality rates for non-variceal upper gastrointestinal bleeding, as is the case in other European countries, non-variceal upper gastrointestinal bleeding remains a serious problem.

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.

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.

Esophageal capsule endoscopy is not the optimal technique to determine the need for primary prophylaxis in patients with cirrhosis

Introduction Capsule endoscopy has been suggested as a potential alternative to endoscopy for detection of esophagogastric varices and severe portal hypertensive gastropathy (PHG). The aim of the study was to determine whether PillCam esophageal capsule endoscopy could replace endoscopy for screening purposes. Material and methods Sixty-two patients with cirrhosis with no previous variceal bleeding had PillCam capsule endoscopy and video endoscopy performed on the same day. Sensitivity, specificity, and positive and negative predictive values (PPV, NPV) of capsule endoscopy were compared to endoscopy for the presence and severity of esophageal and gastric varices, PHG and the need for primary prophylaxis. Patients’ preference was assessed by a questionnaire. Results Four (6%) patients were unable to swallow the capsule. Sensitivity, specificity, PPV and NPV of capsule endoscopy for detecting any esophageal varices (92%, 50%, 92%, 50%), large varices (55%, 91%, 75%, 80%), variceal red signs (58%, 87%, 69%, 80%), PHG (95%, 50%, 95%, 50%), and the need for primary prophylaxis (91%, 57%, 78%, 80%) were not optimal, with only moderate agreement (κ) between capsule and upper GI endoscopy. Had only a capsule endoscopy been performed, 12 (21.4%) patients would have received inappropriate treatment. Capsule endoscopy also failed to detect (0/13) gastric varices. The majority of patients ranked capsule endoscopy as more convenient (69%) and their preferred (61%) method. Conclusions Despite the preference expressed by patients for capsule endoscopy, we believe that upper GI endoscopy should remain the preferred screening method for primary prophylaxis. PMID:27186182

Predicting outcome of acute non-variceal upper gastrointestinal haemorrhage without endoscopy using the clinical Rockall Score.

The Rockall risk scoring system uses clinical criteria and endoscopy to identify patients at risk of adverse outcomes after acute upper gastrointestinal haemorrhage. A clinical Rockall score obtained using only the clinical criteria may be able to predict outcome without endoscopy. To validate the clinical Rockall Score in predicting outcome after acute non-variceal upper gastrointestinal haemorrhage. A retrospective observational study of consecutive patients who were admitted with non-variceal acute upper gastrointestinal haemorrhage was undertaken. Medical records were abstracted using a standardised form. 102 cases were identified (51 men and 51 women; mean age 59 years). 38 (37%) patients considered to be at low risk of adverse outcomes (clinical Rockall Score 0) had no adverse outcomes and did not require transfusion. Patients with a clinical Rockall Score of 1-3 had no adverse outcomes, although 13 of 45 (29%) patients required blood transfusions. Clinical Rockall Scores >3 (n = 19) were associated with adverse outcomes (rebleeding in 4 (21%), surgery in 1 (5%) and death in 2 (10%)). The clinical Rockall Score without endoscopy may be a useful prognostic indicator in this cohort of patients with acute non-variceal upper gastrointestinal haemorrhage. This score may reduce the need for urgent endoscopy in low-risk patients, which can instead be carried out on a more elective outpatient basis.

Drug-induced sleep endoscopy is a diagnostic technique that allows dynamic evaluation of the upper airway during artificial sleep. The lack of a standardized procedure and the difficulties associated with direct visual detection of obstructive events result in poor intraobserver and interobserver reliability, especially when otolaryngology surgeons not experienced in the technique are involved. To describe a drug-induced sleep endoscopy technique implemented with simultaneous polygraphic monitoring of cardiorespiratory parameters (DISE-PG) in patients with a diagnosis of obstructive sleep apnea syndrome and discuss the technique's possible advantages compared with the standard procedure. This prospective cohort study included 50 consecutive patients with obstructive sleep apnea syndrome who underwent DISE-PG from March 1, 2013, to June 30, 2014. A standard protocol was adopted, and all the procedures were carried out in an operation room by an experienced otolaryngology surgeon under the supervision of an anesthesiologist. Endoscopic and polygraphic obstructive respiratory events were analyzed offline in a double-blind setting and randomized order. The feasibility and safety of the DISE-PG technique, as well as its sensitivity in detecting respiratory events compared with that of the standard drug-induced sleep endoscopy procedure. All 50 patients (43 men and 7 women; mean [SD] age, 51.1 [12.1] years) underwent DISE-PG without technical problems or patient difficulties regarding the procedure. As expected, polygraphic scoring was more sensitive than endoscopic scoring in identifying obstructive events (mean [SD] total events, 13.3 [6.8] vs 5.3 [3.6]; mean [SD] difference, 8.8 [5.6]; 95% CI, 7.3 to 10.4; Cohen d, -1.5). This difference was most pronounced in patients with a higher apnea-hypopnea index (AHI) at baseline (mean [SD] difference for AHI >30, 27.1% [31.0%]; 95% CI, -36.2% to 90.4%; Cohen d, 0.2; for AH I >40, 76.0% [35.5%]; 95% CI, 4.6% to 147.4%; Cohen d, 0.5; for AHI >50, 92.2% [37.2%]; 95% CI, 17.3% to 167.1%; Cohen d, 0.6) and a high percentage of hypopneas (≥75% of all obstructive events) at baseline (mean [SD] difference, 20.2% [5.4%]; 95% CI, 9.2% to 31.3%; Cohen d, 1.1). No other anthropomorphic or polygraphic features at baseline were associated with the differences between the DISE-PG and baseline home sleep apnea test. The DISE-PG technique is feasible, safe, and more sensitive at detecting an obstructed breathing pattern than is drug-induced sleep endoscopy alone. The DISE-PG technique could be helpful for accurate comprehension of upper airway obstructive dynamics (ie, degree of obstruction and multilevel pattern) and a nonobstructive breathing pattern (ie, central apneas).

Acute upper gastrointestinal bleeding (UGIB) - initial evaluation and management.

Acute upper gastrointestinal bleeding (UGIB) is the most common reason that the 'on-call' gastroenterologist is consulted. Despite the diagnostic and therapeutic capabilities of upper endoscopy, there is still significant associated morbidity and mortality in patients experiencing acute UGIB, thus this is a true GI emergency. Acute UGIB is divided into non-variceal and variceal causes. The most common type of acute UGIB is 'non-variceal' and includes diagnoses such as peptic ulcer (gastric and duodenal), gastroduodenal erosions, Mallory-Weiss tears, erosive oesophagitis, arterio-venous malformations, Dieulafoy's lesion, and upper GI tract tumours and malignancies. This article focuses exclusively on initial management strategies for acute upper GI bleeding. We discuss up to date and evidence-based strategies for patient risk stratification, initial patient management prior to endoscopy, potential causes of UGIB, role of proton pump inhibitors, prokinetic agents, prophylactic antibiotics, vasoactive pharmacotherapies, and timing of endoscopy.

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

Continuing the Original Stanford Sleep Surgery Protocol From Upper Airway Reconstruction to Upper Airway Stimulation: Our First Successful Case.

PubMed

Liu, Stanley Yung; Riley, Robert Wayne

2017-07-01

In 1993, a surgical protocol for dynamic upper airway reconstruction in patients with obstructive sleep apnea (OSA) was published, and it became commonly known as the Stanford phase 1 and 2 sleep surgery protocol. It served as a platform on which research and clinical studies have continued to perfect the surgical care of patients with OSA. However, relapse is inevitable in a chronic condition such as OSA, and a subset of previously cured surgical patients return with complaints of excessive daytime sleepiness. This report describes a patient who was successfully treated with phase 1 and 2 operations more than a decade previously. He returned at 65 years of age with relapse of moderate OSA, and after workup with polysomnography and drug-induced sleep endoscopy, he underwent upper airway stimulation of the hypoglossal nerve that resulted in a cure of OSA. This case shows why upper airway stimulation is an appropriate option for patients with OSA relapse, after previously successful maxillomandibular advancement. Copyright © 2017.

The incidence and complications of peptic ulcer disease (PUD) have declined, but mortality from bleeding ulcers has remained unchanged. The aims of the current study were to evaluate the significance of PUD among patients admitted for acute upper endoscopy and to evaluate the survival of PUD patients. In this prospective, observational cohort study, data on 1580 acute upper endoscopy cases during 2012-2014 were collected. A total of 649 patients were included with written informed consent. Data on patients' characteristics, living habits, comorbidities, drug use, endoscopy and short-term and long-term survival were collected. Of all patients admitted for endoscopy, 147/649 (23%) had PUD with the main symptom of melena. Of these PUD patients, 35% had major stigmata of bleeding (Forrest Ia-IIb) in endoscopy. Patients with major stigmata had significantly more often renal insufficiency, lower level of blood pressure with tachycardia and lower level of haemoglobin, platelets and ratio of thromboplastin time. No differences in drug use, Charlson comorbidity class, BMI, smoking or alcohol use were found. Of the PUD patients, 31% were Helicobacter pylori positive. The 30-day mortality was 0.7% (95% confidence interval: 0.01-4.7), 1-year mortality was 12.9% (8.4-19.5) and the 2-year mortality was 19.4% (13.8-26.8), with no difference according to major or minor stigmata of bleeding. Comorbidity (Charlson>1) was associated with decreased survival (P=0.029) and obesity (BMI≥30) was associated with better survival (P=0.023). PUD is still the most common cause for acute upper endoscopy with very low short-term mortality. Comorbidity, but not the stigmata of bleeding, was associated with decreased long-term survival.

Recommendations from the American Society of Anesthesiologists suggest that monitoring for apnea using the detection of exhaled carbon dioxide (capnography) is a useful adjunct in the assessment of ventilatory status of patients undergoing sedation and analgesia. There are no data on the utility of capnography in GI endoscopy, nor is the frequency of abnormal ventilatory activity during endoscopy known. The aims of this study were to determine the following: (1) the frequency of abnormal ventilatory activity during therapeutic upper endoscopy, (2) the sensitivity of observation and pulse oximetry in the detection of apnea or disordered respiration, and (3) whether capnography provides an improvement over accepted monitoring techniques. Forty-nine patients undergoing therapeutic upper endoscopy were monitored with standard methods including pulse oximetry, automated blood pressure measurement, and visual assessment. In addition, graphic assessment of respiratory activity with sidestream capnography was performed in all patients. Endoscopy personnel were blinded to capnography data. Episodes of apnea or disordered respiration detected by capnography were documented and compared with the occurrence of hypoxemia, hypercapnea, hypotension, and the recognition of abnormal respiratory activity by endoscopy personnel. Comparison of simultaneous respiratory rate measurements obtained by capnography and by auscultation with a pretracheal stethoscope verified that capnography was an excellent indicator of respiratory rate when compared with the reference standard (auscultation) (r = 0.967, p < 0.001). Fifty-four episodes of apnea or disordered respiration occurred in 28 patients (mean duration 70.8 seconds). Only 50% of apnea or disordered respiration episodes were eventually detected by pulse oximetry. None were detected by visual assessment (p < 0.0010). Apnea/disordered respiration occurs commonly during therapeutic upper endoscopy and frequently precedes the development of hypoxemia. Potentially important abnormalities in respiratory activity are undetected with pulse oximetry and visual assessment.

Sleep specialists usually do not pay much attention to the upper airway in patients who snore, because they can make the diagnosis of sleep-disordered breathing without performing nasopharyngeal endoscopy if they have the Epworth Sleepiness Scale scores and the results of polysomnography. The purpose of this study was to determine the prevalence of benign and malignant tumors and cysts in the upper airway in patients who snore. A retrospective multicenter trial was performed in 4 sleep laboratories. Adult male and female patients whose chief complaint on their first visit was witnessed snoring were enrolled in this study. All of the patients were evaluated by otolaryngologists using nasopharyngeal endoscopy to detect organic diseases in the upper airway. Among 2,923 patients, 2 patients had malignant tumors, 5 had benign tumors, and 2 had cysts in the upper airway. The prevalence of upper airway benign and malignant tumors and cysts among adult male and female patients was 0.24%. Routine detailed nasopharyngeal endoscopy should be carried out in each institution so as not to overlook organic diseases in the upper airway among patients who snore.

Drug-induced sleep endoscopy (DISE) has become an important diagnostic examination tool in the treatment decision process for surgical therapies in the treatment of obstructive sleep apnea (OSA). Currently, there is a variety of regimes for the performance of DISE, which renders comparison and assessment across results difficult. It remains unclear how the different regimes influence the findings of the examination and the resulting conclusions and treatment recommendations. This study aimed to investigate the correlation between increasing levels of sedation (i.e., light, medium, and deep) induced by propofol using a target-controlled infusion (TCI) pump, with the obstruction patterns at the levels of the velum, oropharynx, tongue base, and epiglottis (i.e., VOTE classification). A second goal was the establishment of a sufficient sedation level to enable a reliable decision regarding treatment recommendations. Forty-three patients with OSA underwent a DISE procedure using propofol TCI. Three levels of sedation were defined, depending on entropy levels and assessment of sedation: light sedation, medium sedation, and deep sedation. The evaluation of the upper airway at each level, with increasing sedation, was documented using the VOTE classification. The elapsed time at which each assessment was performed was recorded. Upper airway changes occurred and were measured throughout the DISE procedure. Clinically useful determinations of airway closure occurred at medium sedation; this level of sedation was most probably achieved with a blood propofol concentration of 3.2 μg/ml. In all 43 patients, definite treatment decisions could be made at medium sedation level. Increasing sedation did not result in changes in the treatment decision. Changes in upper airway collapse during DISE with propofol TCI occur at levels of medium sedation. Decisions regarding surgical treatment could be made at this level of sedation.

Upper gastrointestinal (GI) symptoms are common in both HIV and non-HIV-infected patients, but the difference of GI symptom severity between 2 groups remains unknown. Candida esophagitis and erosive esophagitis, 2 major types of esophagitis, are seen in both HIV and non-HIV-infected patients, but differences in GI symptoms that are predictive of esophagitis between 2 groups remain unknown. We aimed to determine whether GI symptoms differ between HIV-infected and non-HIV-infected patients, and identify specific symptoms of candida esophagitis and erosive esophagitis between 2 groups.We prospectively enrolled 6011 patients (HIV, 430; non-HIV, 5581) who underwent endoscopy and completed questionnaires. Nine upper GI symptoms (epigastric pain, heartburn, acid regurgitation, hunger cramps, nausea, early satiety, belching, dysphagia, and odynophagia) were evaluated using a 7-point Likert scale. Associations between esophagitis and symptoms were analyzed by the multivariate logistic regression model adjusted for age, sex, and proton pump inhibitors.Endoscopy revealed GI-organic diseases in 33.4% (2010/6.011) of patients. The prevalence of candida esophagitis and erosive esophagitis was 11.2% and 12.1% in HIV-infected patients, respectively, whereas it was 2.9% and 10.7 % in non-HIV-infected patients, respectively. After excluding GI-organic diseases, HIV-infected patients had significantly (P < 0.05) higher symptom scores for heartburn, hunger cramps, nausea, early satiety, belching, dysphagia, and odynophagia than non-HIV-infected patients. In HIV-infected patients, any symptom was not significantly associated with CD4 cell count. In multivariate analysis, none of the 9 GI symptoms were associated with candida esophagitis in HIV-infected patients, whereas dysphagia and odynophagia were independently (P < 0.05) associated with candida esophagitis in non-HIV-infected patients. However, heartburn and acid regurgitation were independently (P < 0.05) associated with erosive esophagitis in both patient groups. The internal consistency test using Cronbach's α revealed that the 9 symptom scores were reliable in both HIV (α, 0.86) and non-HIV-infected patients (α, 0.85).This large-scale endoscopy-based study showed that HIV-infected patients have greater GI symptom scores compared with non-HIV-infected patients even after excluding GI-organic diseases. None of the upper GI symptoms predict candida esophagitis in HIV-infected patients, but dysphagia and odynophagia predict candida esophagitis in non-HIV-infected patients. Heartburn and acid regurgitation predict erosive esophagitis in both patient groups.

Background Cigarette use is associated with esophageal adenocarcinoma, and cross-sectional studies suggest an association between smoking and Barrett's esophagus. Aims We sought to examine prospectively the influence of smoking on the risk for Barrett's esophagus. Methods This was a prospective cohort study among 20,863 women within the Nurses’ Health Study who underwent upper gastrointestinal endoscopy for any reason between 1980 and 2006. We assessed the association between smoking and pathologically-confirmed Barrett's esophagus (n=377). Self-reported data on smoking and potential confounding variables were collected from biennial questionnaires. Results Compared to women who never smoked, former smokers who used 1-24 cigarettes/day had a multivariate odds ratio for Barrett's esophagus of 1.25 (95% CI 0.99-1.59), former smokers who used ≥25 cigarettes/day had a multivariate odds ratio of 1.52 (95% CI 1.04-2.22), current smokers who used 1-24 cigarettes/day had a multivariate odds ratio of 0.89 (95% CI 0.54-1.45), and current smokers who used ≥25 cigarettes/day had a multivariate odds ratio of 0.92 (95% CI 0.34-2.54). The risk for Barrett's esophagus increased significantly with increasing pack-years smoked among former (P = 0.008), but not current smokers (p=0.99), especially when considering exposure ≥25 years prior to index endoscopy. Results were similar among women reporting regular heartburn/acid-reflux one or more times a week, and were not accounted for by changes in weight. Conclusions Heavy, remote smoking is associated with an increased risk for Barrett's esophagus. This finding suggests a long latency period between exposure and development of the disease, even after discontinuation of smoking. PMID:21448698

Aim of the Study. To compare the effect of glossopharyngeal nerve block with topical anesthesia on the tolerance of patients to upper gastrointestinal endoscopy. Methods. We performed a clinical trial in one hundred patients undergoing upper gastrointestinal endoscopy. Subjects were randomly assigned to one of the following two groups: (1) treatment with bilateral glossopharyngeal nerve block (GFNB) and intravenous midazolam or (2) treatment with topical anesthetic (TASS) and intravenous midazolam. We evaluated sedation, tolerance to the procedure, hemodynamic stability, and adverse symptoms. Results. We studied 46 men and 54 women, from 17 to 78 years of age. The procedure was reported without discomfort in 48 patients (88%) in the GFNB group and 32 (64%) in the TAAS group; 6 patients (12%) in GFNB group and 18 (36%) in TAAS group reported the procedure as little discomfort (χ (2) = 3.95, P = 0.04). There was no difference in frequency of nausea (4% in both groups) and retching, 4% versus 8% for GFNB and TASS group, respectively (P = 0.55). Conclusions. The use of glossopharyngeal nerve block provides greater comfort and tolerance to the patient undergoing upper gastrointestinal endoscopy. It also reduces the need for sedation.

A 68-year-old man presented to the emergency department with haematemesis and shock. Upper endoscopy and selective angiography could not identify the source of bleeding. He underwent selective embolisation of the gastroduodenal artery. The patient then had a period of about 24 hours with relative haemodynamic stability before having another episode of massive upper gastrointestinal bleed. A second attempt to embolise the common hepatic artery and distal coeliac axis was unsuccessful. Hence, he was urgently taken to the operating room for exploratory laparotomy. The source of bleeding could not be identified in the operating room. The patient went into cardiac arrest and expired. Autopsy revealed a fistula between proximal jejunum and a previously unknown abdominal aortic aneurysm (AAA). We present an entity that has only been described a few times in the literature while highlighting the importance of having a broad differential with upper gastrointestinal bleeding, especially when the source is not clearly evident. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Background and study aim  Upper endoscopy is the most common method for the diagnosis of upper gastrointestinal tract diseases. The aim of this study was to determine whether premedication with simethicone or N -acetylcysteine improves mucosal visualization during upper endoscopy. Patients and methods  This was a randomized, double-blind, placebo-controlled study of 297 patients scheduled for upper endoscopy who were premedicated 15 - 30 minutes before the procedure with: 100 mL of water (placebo, group A); water plus 100 mg simethicone (group B); water plus 100 mg simethicone plus 600 mg N -acetylcysteine (group C). The primary outcome measure was the quality of mucosal visualization (score: excellent, adequate or inadequate). Results  The addition of simethicone (group B) or simethicone plus N -acetylcysteine to the water (group C) improved the visualization scores of endoscopies compared with water alone (group A). In particular, groups B and C produced a significantly higher percentage of endoscopies with excellent visualization for the esophagus (91.1 % and 86.7 %, respectively, vs. 71.4 % in group A; P  < 0.001) and stomach (76.2 % and 74.5 % vs. 38.8 % in group A; P  < 0.001). For the duodenum, the use of simethicone also showed an increase in the endoscopies with excellent visualization compared with water alone (85.1 % vs. 73.5 %; P  = 0.042). There were no significant differences in scores between groups B and C or between gastric scores in patients with previous subtotal gastrectomy (B and C vs. A): 60.0 % and 42.1 % vs. 28.6 % ( P  = 0.14). The rate of reported lesions was higher in group B but without statistical significance. Conclusions  Premedication with simethicone resulted in better mucosal visibility. Such premedication might improve diagnostic yield, and should be considered for standard practice.

Response of patients to upper gastrointestinal endoscopy: effect of inherent personality traits and premedication with diazepam.

Webberley, M J; Cuschieri, A

1982-01-01

The influence of personality traits on the reaction of patients to upper gastrointestinal endoscopy was studied prospectively in 86 patients. High N (neuroticism) scores on the Eysenck personality inventory were associated with poor tolerance to and future compliance with the procedure. Although premedication with diazepam did not affect the degree of discomfort and distress during the procedure, it guaranteed acceptance of repeat endoscopy by virtue of its strong amnesic effect. By contrast, not giving premedication to patients who were anxious and had high N scores jeopardized future compliance. These findings suggest that a version of the Eysenck personality inventory should be used to assess patients' neurotic phenotype and their need for premedication before endoscopy. Alternatively, all patients might be given premedication. PMID:6807436

To determine different clinical presentationsand disease location demarcatedby upper and lower gastrointestinal endoscopyand relevant histopathologyin children diagnosed with inflammatory bowel disease (IBD). This is 5 years (2010 to 2015) retrospective studyconducted at the Aga Khan University Hospitalenrolling65admitted children between 6 months to 15years from either gender, diagnosed with IBD on clinical presentation, endoscopy and biopsy. Different clinical presentations at the time of diagnosis were noted in different categories of the disease. All patients underwent upper and lower (up to the terminal ileum) endoscopy with multiple punch biopsies and histologic assessment of mucosal specimens. All endoscopies were done by paediatric gastroenterologists at endoscopy suite of the hospital and all specimens were reported by the pathology department. ESPGHAN revised criteria for the diagnosis of inflammatory bowel disease in children and an adolescent was used to standardize our diagnosis. Extent of disease on endoscopy and relevant histopathology of the biopsy samples were noted at the time of diagnosis. Data was summarized using mean, standard deviation, numbers and percentages for different variables. Total 56 children were enrolled according to inclusion criteria. There were 34children (61.53%) diagnosed with ulcerative colitis (UC), 10 patients (16.92%) had Crohn'sDisease (CD) and 11 (21.53%) patients were labeled as Indeterminate colitis (IC). Mean age at onset of symptoms was10.03±2.44 and mean age at diagnosis was11.10±2.36. Abdominal pain (80%) and chronic diarrhea (70%) were common symptoms in CD whereas bloody diarrhea (79.41%) and rectal bleeding(64.70%)were common presentation in UC. Patients diagnosed with indeterminate colitis(IC) had similar clinical features as in UC patients. Only 7% patients had some extra-intestinal features in the form of joint pain and/or uveitis. Aspartate aminotransferase level (95.18 ±12.89) was relatively high in patients withCD in comparison with other categories of IBD. Endoscopic findings and relevant histopathology of biopsy samples in UC showed 65% patient had pan-colitis and 13 % with disease restricted to rectum only whereas in CD 70% patient had disease in ileo-colon and only 10 % had involvement of ileum at the time diagnosis. Patients with UC dominated in our cohort. The most common clinical presentation in UC was bloody diarrhea and rectal bleeding and patients with CDhad abdominal pain and chronic diarrhea as predominant clinical features. Extraintestinal features were uncommon in our cohort. In endoscopic findings, pan-colitis was the mostfrequentfinding in UC and ileo-colonwas common location in CD. IC and UC shared common clinical features and disease location on endoscopy.

Importance Drug-induced sleep endoscopy is a diagnostic technique that allows dynamic evaluation of the upper airway during artificial sleep. The lack of a standardized procedure and the difficulties associated with direct visual detection of obstructive events result in poor intraobserver and interobserver reliability, especially when otolaryngology surgeons not experienced in the technique are involved. Objectives To describe a drug-induced sleep endoscopy technique implemented with simultaneous polygraphic monitoring of cardiorespiratory parameters (DISE-PG) in patients with a diagnosis of obstructive sleep apnea syndrome and discuss the technique’s possible advantages compared with the standard procedure. Design, Setting, and Participants This prospective cohort study included 50 consecutive patients with obstructive sleep apnea syndrome who underwent DISE-PG from March 1, 2013, to June 30, 2014. A standard protocol was adopted, and all the procedures were carried out in an operation room by an experienced otolaryngology surgeon under the supervision of an anesthesiologist. Endoscopic and polygraphic obstructive respiratory events were analyzed offline in a double-blind setting and randomized order. Main Outcomes and Measures The feasibility and safety of the DISE-PG technique, as well as its sensitivity in detecting respiratory events compared with that of the standard drug-induced sleep endoscopy procedure. Results All 50 patients (43 men and 7 women; mean [SD] age, 51.1 [12.1] years) underwent DISE-PG without technical problems or patient difficulties regarding the procedure. As expected, polygraphic scoring was more sensitive than endoscopic scoring in identifying obstructive events (mean [SD] total events, 13.3 [6.8] vs 5.3 [3.6]; mean [SD] difference, 8.8 [5.6]; 95% CI, 7.3 to 10.4; Cohen d, –1.5). This difference was most pronounced in patients with a higher apnea-hypopnea index (AHI) at baseline (mean [SD] difference for AHI >30, 27.1% [31.0%]; 95% CI, –36.2% to 90.4%; Cohen d, 0.2; for AH I >40, 76.0% [35.5%]; 95% CI, 4.6% to 147.4%; Cohen d, 0.5; for AHI >50, 92.2% [37.2%]; 95% CI, 17.3% to 167.1%; Cohen d, 0.6) and a high percentage of hypopneas (≥75% of all obstructive events) at baseline (mean [SD] difference, 20.2% [5.4%]; 95% CI, 9.2% to 31.3%; Cohen d, 1.1). No other anthropomorphic or polygraphic features at baseline were associated with the differences between the DISE-PG and baseline home sleep apnea test. Conclusions and Relevance The DISE-PG technique is feasible, safe, and more sensitive at detecting an obstructed breathing pattern than is drug-induced sleep endoscopy alone. The DISE-PG technique could be helpful for accurate comprehension of upper airway obstructive dynamics (ie, degree of obstruction and multilevel pattern) and a nonobstructive breathing pattern (ie, central apneas).

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.

In most European countries, training in GI endoscopy has largely been based on hands-on acquisition of experience in patients rather than on a structured training programme. With the development of training models systematic hands-on training in a variety of diagnostic and therapeutic endoscopy techniques was achieved. Little, however, is known about methods of objectively assessing trainees' performance. We therefore developed an assessment 'score card' for upper GI endoscopy and tested it in endoscopists with various levels of experience. The aim of the study was therefore to assess interobserver variations in the evaluation of trainees. On the basis of textbook and expert opinions a consensus group of eight experienced endoscopists developed a score card for diagnostic upper GI endoscopy with biopsy. The score card includes an assessment of the single steps of the procedure as well as of the times needed to complete each step. This score card was then evaluated in a further conference including ten experts who blindly assessed videotapes of 15 endoscopists performing upper GI endoscopy in a training bio-simulation model (the 'Erlangen Endo-Trainer'). On the basis of their previous experience (i. e. the number of endoscopies performed) these 15 endoscopists were classified into four groups: very experienced, experienced, having some experience and inexperienced. Interobserver variability (IOV) was tested for the various score card parameters (Kendall's rank-correlation coefficient 0.0-0.5 poor, 0.5-1.0 good agreement). In addition, the correlation between the score card assessment and the examiners' experience levels was analysed. Despite poor IOV results for all the parameters tested (Kendall coefficient < 0.3), the assessment parameters correlated well when the examiners' different experience levels were taken into account (correlation coefficient 0.59-0.89, p < 0.05). The score card parameters were suitable for differentiating between the four groups of examiners with different levels of endoscopic experience. As expected with scores involving subjective assessment of performance, the variability between reviewers was substantial. Nevertheless, the assessment score was capable of distinguishing reliably between different experience levels in terms of a good individual observer consistency. The score card can therefore be used to document both training status and progress during endoscopy training courses using bio-simulation models, and this might be able to provide improved quality assurance in GI endoscopy training.

To investigate the structure of dyspeptic symptoms and determine the association between dyspeptic symptoms and endoscopic findings in patients referred for upper gastrointestinal endoscopy by family physicians in a country with a high prevalence of Helicobacter pylori infection. Consecutive outpatients (n=172; median 36 years, range 18-75; 85 male; 87 female) were referred to upper gastrointestinal endoscopy. Patient history was recorded prior to upper gastrointestinal endoscopy using the computer-aided Glasgow Diagnostic System for Dyspepsia (GLADYS). Family physicians used open access endoscopy with a short waiting list. Two biopsies, both from the antrum and the corpus, were taken for histological assessment. Out of the 172 patients studied, 81% (n=139) were H. pylori positive, 65% (n=112) were younger than 45 years. The incidence of peptic ulcer was 44% (n=75). Upper abdominal pain was the predominant complaint in 73% (n=126) of the patients, as well as the most frequent overall complaint. Hunger pain, night pain, periodical nature of symptoms, and history over 2 years were of independent value in differentiating between peptic ulcer and functional dyspepsia. The symptoms of gastroesophageal reflux disease and irritable bowel syndrome predominated in the minority of patients (11% and 5% respectively) but accompanied other complaints in almost 2/3 of the patients. In 32 out of 75 patients with peptic ulcer, the symptoms of irritable bowel syndrome and in 29 cases the presence of frequent heartburn and regurgitation were noted. Classical symptoms are valuable in predicting the diagnosis of peptic ulcer. Heartburn and acid regurgitation are present in both gastroesophageal reflux disease and peptic ulcer. Irritable bowel syndrome is common in patients with peptic ulcer.

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.

Abstract Introduction: A 13-year-old African–American female presented to her primary care physician's office with fatigue, syncope, and hematemesis. After initial evaluation, the patient was referred to pediatric gastroenterology clinic for further evaluation. Main concerns, important findings: An upper gastrointestinal endoscopy was performed to evaluate the source of her bleeding. Endoscopy revealed a 3-cm mass in the lesser curvature of the stomach, and a biopsy of the mass revealed a concern for carcinoid (neuroendocrine) features. Diagnosis: She underwent an open gastrectomy. Post-surgical pathology reports confirmed a well-differentiated neuroendocrine tumor of the stomach. Conclusion: Neuroendocrine tumors of the stomach in children are rare and we presently do not have pediatric-specific diagnostic and treatment guidelines. Although adult-based The North American Neuroendocrine Tumor Society (NANETS) guidelines are helpful, they are clearly not geared toward pediatric patients. To establish pediatric guidelines and to assess effectiveness of treatments, multicenter data collection is essential. In the long run, accumulation of clinically useful treatment information and long-term follow-up guidelines should enable clinicians to improve standard of care given to children with neuroendocrine tumors.

Raman spectroscopy is an optical vibrational technology capable of probing biomolecular changes of tissue associated with cancer transformation. This study aimed to characterize in vivo Raman spectroscopic properties of tissues belonging to different anatomical regions in the upper gastrointestinal (GI) tract and explore the implications for early detection of neoplastic lesions during clinical gastroscopy. A novel fiber-optic Raman endoscopy technique was utilized for real-time in vivo tissue Raman measurements of normal esophageal (distal, middle, and proximal), gastric (antrum, body, and cardia) as well as cancerous esophagous and gastric tissues from 107 patients who underwent endoscopic examinations. The non-negativity-constrained least squares minimization coupled with a reference database of Raman active biochemicals (i.e., actin, histones, collagen, DNA, and triolein) was employed for semiquantitative biomolecular modeling of tissue constituents in the upper GI. A total of 1189 in vivo Raman spectra were acquired from different locations in the upper GI. The Raman spectra among the distal, middle, and proximal sites of the esophagus showed no significant interanatomical variability. The interanatomical variability of Raman spectra among normal gastric tissue (antrum, body, and cardia) was subtle compared to cancerous tissue transformation, whereas biomolecular modeling revealed significant differences between the two organs, particularly in the gastroesophageal junction associated with proteins, DNA, and lipids. Cancerous tissues can be identified across interanatomical regions with accuracies of 89.3% [sensitivity of 92.6% (162/175) specificity of 88.6% (665/751)], and of 94.7% [sensitivity of 90.9% (30/33) specificity of 93.9% (216/230)] in the gastric and esophagus, respectively, using partial least squares-discriminant analysis together with the leave-one tissue site-out, cross validation. This work demonstrates that Raman endoscopy technique has promising clinical potential for real-time, in vivo diagnosis and detection of malignancies in the upper GI at the molecular level.

A randomized trial that compared endoscopic and surgical drainage of the pancreatic duct in patients with advanced chronic pancreatitis reported a significant benefit of surgery after a 2-year follow-up period. We evaluated the long-term outcome of these patients after 5 years. Between 2000 and 2004, 39 symptomatic patients were randomly assigned to groups that underwent endoscopic drainage or operative pancreaticojejunostomy. In 2009, information was collected regarding pain, quality of life, morbidity, mortality, length of hospital stay, number of procedures undergone, changes in pancreatic function, and costs. Analysis was performed according to an intention-to-treat principle. During the 79-month follow-up period, one patient was lost and 7 died from unrelated causes. Of the patients treated by endoscopy, 68% required additional drainage compared with 5% in the surgery group (P = .001). Hospital stay and costs were comparable, but overall, patients assigned to endoscopy underwent more procedures (median, 12 vs 4; P = .001). Moreover, 47% of the patients in the endoscopy group eventually underwent surgery. Although the mean difference in Izbicki pain scores was no longer significant (39 vs 22; P = .12), surgery was still superior in terms of pain relief (80% vs 38%; P = .042). Levels of quality of life and pancreatic function were comparable. In the long term, symptomatic patients with advanced chronic pancreatitis who underwent surgery as the initial treatment for pancreatic duct obstruction had more relief from pain, with fewer procedures, than patients who were treated endoscopically. Importantly, almost half of the patients who were treated with endoscopy eventually underwent surgery. Copyright © 2011 AGA Institute. Published by Elsevier Inc. All rights reserved.

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.

Numerous studies have addressed musculoskeletal disorders in the international working population. The literature indicates that injuries exist at astounding rates with significant economic impact. Attempts have been made by government, private industry, and special interest groups to address the issues related to the occurrence and prevention of musculoskeletal injuries. Because of the limited research on the gastrointestinal (GI) endoscopy nursing sector, this descriptive, correlational study explored the incidence of upper extremity injuries in GI endoscopy nurses and technicians in the United States. A total of 215 subjects were included in the study. Findings show that upper extremity injuries exist among nurses working in GI endoscopy. Twenty-two percent of respondents missed work for upper extremity injuries. The findings also show that the severity of disability is related to the type of work done, type of assistive aids available at work, and whether or not ergonomic or physiotherapy assessments were provided at the place of employment. In reference to rate of injury and the availability of ergonomics and physiotherapy assessments, those who had ergonomic assessments available to them had scores on the Disabilities of the Arm, Shoulder, and Hand (DASH) inventory (indicating upper extremity disability) that were significantly lower (DASH score, 9.96) than those who did not have the assessments available (DASH score, 14.66). The results suggest that there are a significant number of subjects who are disabled to varying degrees and the majority of these are employed in full-time jobs.

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.

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)

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.

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.

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.

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.

With the ever-increasing concern regarding morbidity and mortality associated with diseases of the gastrointestinal tract, the importance of an effective and efficient diagnostic tool cannot be overstated. The standard of care currently is an examination using conventional white light endoscopy. This approach may occasionally overlook areas exhibiting a premalignant change. Numerous image-enhanced modalities have been recently introduced. Narrow band imaging (NBI) appears to be the most prominent of these and perhaps the most commonly used. Thepresent review will focus on some of the newer studies on NBI and its utility in the diagnosis of malignant, pre-malignant and chronic inflammatory conditions of the upper gastrointestinal tract. © 2013 The Authors.

The incidence of acute upper gastrointestinal bleeding is about 85-108/100,000 inhabitants per year, nonvariceal bleeding accounts for 80-90%. Antiplatelet and anticoagulation treatment are the significant risk factors for upper gastrointestinal bleeding. To evaluate the occurrence of upper gastrointestinal bleeding in the general community of patients in a county hospital. And to compare the role played by antiplatelet and anticoagulation drugs and other risk medication. Retrospective analysis of patients over 18 years of age who underwent endoscopy for acute upper gastrointestinal bleeding or anaemia (haemoglobin<100 g/l) with proved source of blood losses in upper gastrointestinal tract during a hospital stay in 2013 (from January to June). We included 111 patients of average age 69±15 years, men 60%. Nonvariceal bleeding accounted for 90% of the cases. None of the patients with variceal bleeding (10% of patients) took antiplatelet or anticoagulation therapy. There were 100 patients with nonvariceal bleeding of average age 70±15, 61% men. With the symptoms of acute bleeding (hematemesis, melena) presented in 73% of patients. The most frequent cause of bleeding was gastric and duodenal ulcer (54%). 32% of patients with nonvariceal bleeding had antiplatelets, 19% anticoagulants and 10% used nonsteroidal anti-inflammatory drugs, selective serotonin reuptake inhibitors or corticosteroids. 30-days mortality of patients with nonvariceal bleeding was 11%, annual mortality was 23%. There was no significant difference in mortality, blood transfusion requirements or surgical intervention between the patients with antithrombotic agents and without them. 25% of patients (8 patients) using acetylsalicylic acid did not fulfil the indication for this treatment. Among the patients examined by endoscopy for symptomatic nonvariceal bleeding and/or anaemia (haemoglobin<100 g/l) significantly higher portions of patients are taking antiplatelet rather than anticoagulation therapy. This may be caused by greater use of these drugs in the population, but on the other hand it may reflect an association with greater risk of gastrointestinal bleeding. With regard to that, it is alarming, that there still exists a nonnegligible percentage of patients taking acetylsalicylic acid even though they do not meet the indication for the prescription according to the guidelines.

Diagnosis and management of nonvariceal upper gastrointestinal hemorrhage: European Society of Gastrointestinal Endoscopy (ESGE) Guideline.

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.

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.

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.

Upper and Lower Urinary Tract Endoscopy Training on Thiel-embalmed Cadavers.

PubMed

Bele, Uros; Kelc, Robi

2016-07-01

To evaluate Thiel-embalmed cadavers as a new training model for urological endoscopy procedures. Twelve urologists performed upper and lower urinary tract endoscopies on 5 different Thiel-embalmed cadavers to evaluate this potentially new training model in urological endoscopic procedural training. Using a 5-point Likert scale, the participants assessed the quality of the tissue and the overall experience of the endoscopy in comparison to a live patient procedure. Thiel-embalmed cadavers have shown to mimic live patient endoscopy of the upper and lower urinary tract in terms of almost identical overall anatomical conditions and manipulation characteristics of the tissue. The mucosa of the urethra and ureters showed similar colors and consistency in comparison to a live patient, whereas bladder mucosa was lacking the visibility of the vessels, thus was unsuitable for identifying any mucosal abnormalities. The flexibility of the muscles allowed for proper patient positioning, whereas the loss of muscle tonus made ureteroscopy more difficult although sufficiently comparable to the procedure done in a live patient. Thiel-embalmed cadavers have already been proven to be a suitable training model for several medical procedures. They are known for preserving tissue color, consistency, and flexibility without the irritant odors or risk of infection, which make them resemble live patients with real-life surgical challenges. The results of our study strongly suggest that despite some minor drawbacks, Thiel-embalmed cadavers are a suitable simulation model for initial training of urethrocystoscopy and ureteroscopy.

Aortoduodenal fistula in a patient on intravitreal bevacizumab injections: a case report.

PubMed

Pepper, Amber N; Valenzuela, Mauricio O; Oller, Kellee L

2015-01-01

An 88-year-old woman on long-term intravitreal bevacizumab presented with acute gastrointestinal hemorrhage. She was stabilized and underwent nonrevealing upper endoscopy. She continued to require intermittent blood transfusions, and resulting computed tomography of the abdomen revealed an aortoduodenal fistula. The patient was undergoing treatment for her macular degeneration with intravitreal bevacizumab, an angiogenesis inhibitor frequently used to treat solid organ malignancies. Systemic administration has been associated with serious adverse events, including gastrointestinal hemorrhage, perforation, and fistula formation. Intravitreal bevacizumab has been used off-label to treat macular degeneration, but data on the safety of this therapy are limited. Given her lack of other risk factors, the authors postulate a potential association between intravitreal bevacizumab and aortoduodenal fistula formation in this patient.

Objective. In the present study, we aimed to investigate epidemiological, clinical, and etiological characteristics of acute upper gastro-intestinal bleeding. Materials and Methods. This retrospective study was conducted between January 2003 and December 2008. It concerned all cases of acute upper gastroduodenal bleeding benefited from an urgent gastro-intestinal endoscopy in our department in Morocco. Characteristics of patients were evaluated in terms of age, gender, medical history, presenting symptoms, results of rectal and clinical examinations, and endoscopy findings. Results. 1389 cases were registered. As 66% of the patients were male, 34% were female. Mean age was 49. 12% of patients had a history of previous hemorrhage, and 26% had a history of NSAID and aspirin use. Endoscopy was performed in 96%. The gastroduodenal ulcer was the main etiology in 38%, followed by gastritis and duodenitis in 32.5%. Conclusion. AUGIB is still a frequent pathology, threatening patients' life. NSAID and aspirin are still the major risk factors. Their impact due to peptic ulcer remains stable in our country. PMID:21991509

To describe the multidetector-row computed tomography enterographic (MD-CTE) features of the ileal-anal pouch after ileal pouch anal anastomosis (IPAA) surgery and correlate them with pouch endoscopy and histopathologic findings. All MD-CTE examinations performed on patients who underwent IPAA from July 1, 2005 to December 1, 2010 (n = 35; 16 [45.7%] men; mean age, 37.7 years; age range, 22-72 years) were retrospectively evaluated in consensus by 2 radiologists. All studies were evaluated for the presence of multiple imaging features. Two radiographic scores were then calculated: a total radiographic score and a radiographic active inflammation score. In patients who underwent MD-CTE, pouch endoscopy, and biopsy within 30 days (n = 13), both scores were correlated with findings on pouch endoscopy and histopathology. Of the 35 patients, 33 (94%) had at least one MD-CTE finding of active or chronic pouch inflammation and 27 patients (77%) had at least one MD-CTE finding of active pouch inflammation. Of the 13 patients who underwent endoscopy and biopsy, the total radiographic score demonstrated a strong positive correlation with endoscopic score (r = 0.81; P = 0.001) and a moderate positive correlation with histopathologic score (r = 0.56; P = 0.047). The radiographic active inflammation score demonstrated a strong positive correlation with endoscopic score (r = 0.83; P = 0.0004), but only a weak nonsignificant positive correlation with histopathologic score (r = 0.492, P = 0.087). In patients who had IPAA surgery, findings on MD-CTE correlate positively with findings on pouch endoscopy and histopathology and are sensitive measures for pouch inflammation with high positive predictive value. Thus, MD-CTE can be a useful noninvasive test in the early evaluation of symptomatic patients.

2012-01-01

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.

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.

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.

An 82-year-old male presented with a chief complaint of upper abdominal pain. Subsequently, a bezoar and a gastric ulcer were detected by upper gastrointestinal endoscopy. The bezoar was dark green in color and extremely hard, having a major axis of 7 cm. After hospitalization, 500-1000 ml/day of Coca-Cola was orally administered continuously for 3 weeks. Thereafter, the bezoar decreased in size to a major axis of 4 cm and showed a softening trend. Therefore, lithotripsy was thereafter carried out under endoscopy using forceps.

Determine the feasibility of using power spectrum of the sleep electroencephalogram (EEG) as a more sensitive tool than sleep architecture to evaluate the relationship between gastroesophageal reflux disease (GERD) and sleep. GERD has been shown to adversely affect subjective sleep reports but not necessarily objective sleep parameters. Data were prospectively collected from symptomatic patients with heartburn. All symptomatic patients underwent upper endoscopy. Patients without erosive esophagitis underwent pH testing. Sleep was polygraphically recorded in the laboratory. Spectral analysis was performed to determine the power spectrum in 4 bandwidths: delta (0.8 to 4.0 Hz), theta (4.1 to 8.0 Hz), alpha (8.1 to 13.0 Hz), and beta (13.1 to 20.0 Hz). Eleven heartburn patients were included in the GERD group (erosive esophagitis) and 6 heartburn patients in the functional heartburn group (negative endoscopy, pH test, response to proton pump inhibitors). The GERD patients had evidence of lower average delta-power than functional heartburn patients. Patients with GERD had greater overall alpha-power in the latter half of the night (3 hours after sleep onset) than functional heartburn patients. No significant differences were noted in conventional sleep stage summaries between the 2 groups. Among heartburn patients with GERD, EEG spectral power during sleep is shifted towards higher frequencies compared with heartburn patients without GERD despite similar sleep architecture. This feasibility study demonstrated that EEG spectral power during sleep might be the preferred tool to provide an objective analysis about the effect of GERD on sleep.

Objective This study was performed to compare the functional and anatomical results of endoscopic-assisted and temporary keratoprosthesis (TKP)-assisted vitrectomy in patients with combat ocular trauma (COT). Methods The medical records of 14 severely injured eyes of 12 patients who underwent endoscopy or TKP implantation in combination with vitreoretinal surgery from 2007 to 2015 were retrospectively evaluated. The patients' ocular history and functional and anatomic anterior and posterior segment results were analyzed. Results Eight eyes (57%) underwent TKP-assisted vitrectomy and six eyes (43%) underwent endoscopic vitrectomy. The most common cause of COT was detonation of improvised explosive devices (72%), and the most common type of injury was an intraocular foreign body (50%). The median time from trauma to surgery and the median surgical time were significantly shorter in the endoscopy than TKP group. The postoperative functional and anatomical results were not significantly different between the two groups. Conclusions TKP-assisted vitrectomy should be performed in eyes requiring extensive bimanual surgery. In such cases, a corneal graft must be preserved for the TKP at the end of the surgery. Endoscopy shortens the surgical time and can reduce the complication rate.

Abstract Upper gastrointestinal (GI) symptoms are common in both HIV and non-HIV-infected patients, but the difference of GI symptom severity between 2 groups remains unknown. Candida esophagitis and erosive esophagitis, 2 major types of esophagitis, are seen in both HIV and non-HIV-infected patients, but differences in GI symptoms that are predictive of esophagitis between 2 groups remain unknown. We aimed to determine whether GI symptoms differ between HIV-infected and non-HIV-infected patients, and identify specific symptoms of candida esophagitis and erosive esophagitis between 2 groups. We prospectively enrolled 6011 patients (HIV, 430; non-HIV, 5581) who underwent endoscopy and completed questionnaires. Nine upper GI symptoms (epigastric pain, heartburn, acid regurgitation, hunger cramps, nausea, early satiety, belching, dysphagia, and odynophagia) were evaluated using a 7-point Likert scale. Associations between esophagitis and symptoms were analyzed by the multivariate logistic regression model adjusted for age, sex, and proton pump inhibitors. Endoscopy revealed GI-organic diseases in 33.4% (2010/6.011) of patients. The prevalence of candida esophagitis and erosive esophagitis was 11.2% and 12.1% in HIV-infected patients, respectively, whereas it was 2.9% and 10.7 % in non-HIV-infected patients, respectively. After excluding GI-organic diseases, HIV-infected patients had significantly (P < 0.05) higher symptom scores for heartburn, hunger cramps, nausea, early satiety, belching, dysphagia, and odynophagia than non-HIV-infected patients. In HIV-infected patients, any symptom was not significantly associated with CD4 cell count. In multivariate analysis, none of the 9 GI symptoms were associated with candida esophagitis in HIV-infected patients, whereas dysphagia and odynophagia were independently (P < 0.05) associated with candida esophagitis in non-HIV-infected patients. However, heartburn and acid regurgitation were independently (P < 0.05) associated with erosive esophagitis in both patient groups. The internal consistency test using Cronbach's α revealed that the 9 symptom scores were reliable in both HIV (α, 0.86) and non-HIV-infected patients (α, 0.85). This large-scale endoscopy-based study showed that HIV-infected patients have greater GI symptom scores compared with non-HIV-infected patients even after excluding GI-organic diseases. None of the upper GI symptoms predict candida esophagitis in HIV-infected patients, but dysphagia and odynophagia predict candida esophagitis in non-HIV-infected patients. Heartburn and acid regurgitation predict erosive esophagitis in both patient groups. PMID:26632738

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.

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.

Fluconazole Resistant Candida Oesophagitis in Immunocompetent Patients: Is Empirical Therapy Justifiable?

PubMed Central

Kakati, Barnali; Biswas, Debasis; Sahu, Shantanu

2015-01-01

Introduction C. albicans (Candida albicans) is the foremost cause of fungal oesophagitis, however other species such as Candida tropicalis, Candida krusei and Candida stellatoidea have also been implicated to cause this condition. Although, numerous studies have identified risk factors for C. albicans oesophagitis, data for non- C. albicans species is still sparse. Aim To determine the aetiology of Candida oesophagitis in our medical centre over a two year period. Additionally, to investigate predisposing conditions for oesophageal candidiasis caused by different Candida species. Material and Methods All consecutive patients posted for upper gastrointestinal endoscopy at the endoscopy unit of a tertiary care hospital in north India with findings consistent with oesophagitis were screened for the presence of Candida oesophagitis by performing KOH (potassium hydroxide) examination and culture on SDA (Sabouraud’s dextrose agar). Antifungal susceptibility testing as per CLSI guidelines was performed for fluconazole, a most common empirically prescribed antifungal for the condition. Results A total of 1868 patients with no known immune-compromised condition underwent upper gastroscopy at our centre during the study period. The prevalence of Candida oesophagitis was 8.7% (n = 163). C. albicans was recovered from majority of infections (52.1%), followed by C. tropicalis (24%), C. parapsilosis (13.4%), C. glabrata (6.9%) and C. krusei (3.6%). Alarmingly, among the C. albicans isolates 8.6% were resistant to fluconazole. Conclusion With rising reports of antifungal drug resistance among the isolates of Candida species, an increasing prevalence of this organism could have an impact on the treatment of Candidal oesophagitis and it should be approached with caution by the clinician.

We present a case in which we used a thoracoscopic approach for resection of multiple esophageal carcinomas diagnosed 33 years after surgery for esophageal achalasia. A 68-year-old Japanese man had been diagnosed with esophageal achalasia and underwent surgical treatment 33 years earlier. He was examined at our hospital for annual routine checkup in which upper gastrointestinal endoscopy showed a "0-IIb+IIa" lesion in the middle esophagus. Iodine staining revealed multiple irregularly shaped iodine-unstained areas, the diagnosis of which was esophageal carcinoma. Thoracoscopic subtotal esophagectomy was performed. Esophageal carcinoma may occur many years after surgery for esophageal achalasia, even if the passage symptoms have improved. So, long-term periodic follow-up is necessary for detection of carcinoma at an earlier stage.

We present a case in which we used a thoracoscopic approach for resection of multiple esophageal carcinomas diagnosed 33 years after surgery for esophageal achalasia. A 68-year-old Japanese man had been diagnosed with esophageal achalasia and underwent surgical treatment 33 years earlier. He was examined at our hospital for annual routine checkup in which upper gastrointestinal endoscopy showed a “0-IIb+IIa” lesion in the middle esophagus. Iodine staining revealed multiple irregularly shaped iodine-unstained areas, the diagnosis of which was esophageal carcinoma. Thoracoscopic subtotal esophagectomy was performed. Esophageal carcinoma may occur many years after surgery for esophageal achalasia, even if the passage symptoms have improved. So, long-term periodic follow-up is necessary for detection of carcinoma at an earlier stage. PMID:28951795

Splenic artery aneurysm is rare and its diagnosis is challenging due to the nonspecific nature of the clinical presentation. We report a case of a splenic artery aneurysm in which the patient presented with chronic dyspepsia and multiple episodes of minor intragastric bleeding. A 60-year-old, previously healthy Sri Lankan man presented with four episodes of hematemesis and severe dyspeptic symptoms over a period of 6 months. The results of two initial upper gastrointestinal endoscopies and an abdominal ultrasound scan were unremarkable. A third upper gastrointestinal endoscopy detected a pulsatile bulge at the posterior wall of the gastric antrum. A contrast-enhanced computed tomogram of his abdomen detected a splenic artery aneurysm measuring 3 × 3 × 2.5 cm. While awaiting routine surgery, he developed a torrential upper gastrointestinal bleeding and shock, leading to emergency laparotomy. Splenectomy and en bloc resection of the aneurysm with the posterior stomach wall were performed. Histology revealed evidence for a true aneurysm without overt, acute, or chronic inflammation of the surrounding gastric mucosa. He became completely asymptomatic 2 weeks after the surgery. Splenic artery aneurysms can result in recurrent upper gastrointestinal bleeding. The possibility of impending catastrophic bleeding should be remembered when managing patients with splenic artery aneurysms after a minor bleeding. Negative endoscopy and ultrasonography should require contrast-enhanced computed tomography to look for the cause of recurrent upper gastrointestinal bleeding.

Hemostatic powder TC-325 in the management of upper and lower gastrointestinal bleeding: a two-year experience at a single institution.

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.

A 25-year-old male presented with hematemesis, epigastric pain, and melena. He had dyspepsia with significant weight loss for 3 months period. On clinical examination, he was pale with no organomegaly or lymphadenopathy. The X-ray chest was normal, and ultrasound abdomen was normal. Upper GI endoscopy revealed nodularity and ulceration along proximal part of lesser curvature of the stomach. CT scan abdomen showed thickening of lesser curvature just below gastro-esophageal junction. The biopsies were negative for malignancy. Repeat upper GI endoscopy showed a nonhealing ulcer, on repeat well biopsies taken from the base of ulcer primary gastric tuberculosis was diagnosed. It showed many epithelioid cell granulomas and multinucleated giant cells with caseous necrosis on histology. Acid-fast bacilli on Zeil Neelsen staining and TB PCR were positive for Mycobacterium tuberculosis. He was put on four-drug anti-tuberculous treatment. On follow-up, the patient gradually improved and regained weight. Repeat upper GI endoscopy done after 8 weeks showed healing of the ulcer with decrease in nodularity.

To determine correlations between symptoms, nasal endoscopy findings, and computed tomography (CT) scan findings in post-surgical chronic rhinosinusitis (CRS) patients. Cross-sectional. A total of 51 CRS patients who had undergone endoscopic sinus surgery (ESS) completed symptom questionnaires, underwent endoscopy, and received an in-office sinus CT scan during one clinic visit. For metrics, we used the Sinonasal Outcomes Test-20 (SNOT-20) questionnaire, visual analog symptom scale (VAS), Lund-Kennedy endoscopy scoring scale, and Lund-MacKay (LM) CT scoring scale. We determined Pearson correlation coefficients, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) between scores for symptoms, endoscopy, and CT. The SNOT-20 score and most VAS symptoms had poor correlation coefficients with both endoscopy and CT scores (0.03-0.24). Nasal drainage of pus, nasal congestion, and impaired sense of smell had moderate correlation coefficients with endoscopy and CT (0.24-0.42). Endoscopy had a strong correlation coefficient with CT (0.76). Drainage, edema, and polyps had strong correlation coefficients with CT (0.80, 0.69, and 0.49, respectively). Endoscopy had a PPV of 92.5% and NPV of 45.5% for detecting an abnormal sinus CT (LM score ≥1). In post-ESS CRS patients, most symptoms do not correlate well with either endoscopy or CT findings. Endoscopy and CT scores correlate well. Abnormal endoscopy findings have the ability to confidently rule in the presence of CT opacification, thus validating the importance of endoscopy in clinical decision making. However, a normal endoscopy cannot assure a normal CT. Thus, symptoms, endoscopy, and CT are complementary in the evaluation of the post-ESS CRS patient.

Narrow band imaging with magnification enables detailed assessment of duodenal villi and may be useful in predicting the presence of villous atrophy or normal villi. We aimed to assess the morphology of duodenal villi using magnification narrow band imaging and correlate it with histology findings in patients with clinically suspected malabsorption syndrome. Patients with clinical suspicion of malabsorption presenting at a tertiary care center were prospectively recruited in this diagnostic intervention study. Patients underwent upper gastrointestinal endoscopy using magnification narrow band imaging. The villous morphology in the second part of the duodenum was assessed independently by two endoscopists and the presence of normal or atrophic villi was recorded. Biopsy specimen was obtained from the same area and was examined by two pathologists together. The sensitivity and specificity of magnification narrow band imaging in detecting the presence of duodenal villous atrophy was calculated and compared to the histology. One hundred patients with clinically suspected malabsorption were included in this study. Sixteen patients had histologically confirmed villous atrophy. The sensitivity and specificity of narrow band imaging in predicting villous atrophy was 87.5% and 95.2%, respectively, for one endoscopist. The corresponding figures for the second endoscopist were 81.3% and 92.9%, respectively. The interobserver agreement was very good with a kappa value of 0.87. Magnification narrow band imaging performed very well in predicting duodenal villous morphology. This may help in carrying out targeted biopsies and avoiding unnecessary biopsies in patients with suspected malabsorption. © 2014 The Authors.

Most delivery devices used for esophageal stents for obstructing esophageal cancer have a diameter of 5-8 mm, a size that is too large to pass through the endoscopic working channel. The conventional esophageal stent requires multiple endoscopic procedures for implantation. The purpose of the present study was to evaluate the clinical feasibility of a newly developed fully covered, self-expanding, through-the-scope (TTS) esophageal stent in a porcine model. Eight mini pigs were used. Each animal underwent placement of a fully covered TTS stent (Hanarostent® Esophagus TTS) and the upper part of the stent was fixed by suturing with nylon. Fluoroscopy was carried out every week to assess migration of the stent. Follow-up endoscopy was done every month for 3 months to evaluate the status of the membrane, stent mesh, grade of tissue hyperplasia, and mucosal changes at both ends of the stent. All stents were successfully and easily deployed, and were placed without any distortion in the stent or without rupture of the membrane. In two cases, stent migration was observed after 8 weeks. No case of membrane disruption, stent mesh disruption or tissue hyperplasia at either end of the stent was found at the completion of the study. Our findings indicate that the new fully covered self-expanding TTS esophageal stent is easy and simple to implant, and no significant distortion of mesh or disruption of membrane was observed. © 2013 The Authors.

Background An 82-year-old male presented with a chief complaint of upper abdominal pain. Subsequently, a bezoar and a gastric ulcer were detected by upper gastrointestinal endoscopy. Case presentation The bezoar was dark green in color and extremely hard, having a major axis of 7 cm. After hospitalization, 500–1000 ml/day of Coca-Cola was orally administered continuously for 3 weeks. Conclusion Thereafter, the bezoar decreased in size to a major axis of 4 cm and showed a softening trend. Therefore, lithotripsy was thereafter carried out under endoscopy using forceps.

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.

Preventing missed appointments, or "no-shows," is an important target in improving efficient patient care and lowering costs in gastrointestinal endoscopy practices. We aimed to investigate whether a nurse telephone call would reduce no-show rates for endoscopic appointments, and to determine if hiring and maintaining a nurse dedicated to pre-endoscopy phone calls is economically advantageous. Our secondary aim was to identify predictors of no-shows to endoscopy appointments. We hired and trained a full-time licensed nurse to make a telephone call to patients 7 days before their scheduled upper endoscopy or colonoscopy. We compared this intervention with a previous reminder system involving mailed reminders. The effect of the intervention and impact of other predictors of no-shows were analyzed in 2 similar preintervention and postintervention patient cohorts. A mixed effects logistic regression model was used to estimate the association of the odds of being a no-show to the scheduled appointment and the characteristics of the patient and visit. An analysis of costs was performed that included the startup and maintenance costs of the intervention. We found that a nurse phone call was associated with a 33% reduction in the odds of a no-show visit (odds ratio, 0.67; 95% confidence interval, 0.50-0.91), adjusting for gender, age, partnered status, insurer type, distance from the endoscopy center, and visit type. The recovered reimbursement during the study period was $48,765, with net savings of $16,190 when accounting for the maintenance costs of the intervention; this resulted in a net revenue per annum of $43,173. We found that endoscopy practices may increase revenue, improve scheduling efficiency, and maximize resource utilization by hiring a nurse to reduce no-shows. Predictors of no-shows to endoscopy included unpartnered or single patients, commercial or managed care, being scheduled for colonoscopy as opposed to upper endoscopy, and being scheduled for a screening or surveillance colonoscopy.

Cerebral Arterial Gas Embolism During Upper Endoscopy.

PubMed

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.

2010-01-01

Purpose Gastric emptying has been evaluated by scintigraphy in spite of its limitations of time consumption, cost, and danger of radioisotope. Endoscopy is a simple technique, however, its validation for gastric emptying and quantification of food has not yet been investigated. The aim of our study was to assess endoscopic gastric emptying compared with scintigraphy and radiopaque markers (ROMs) studies. We also investigated the effect of a single dose of mosapride on gastric emptying. Materials and Methods Fifteen healthy volunteers underwent scintigraphy. Next day, subjects received a standard solid meal with ROMs and underwent endoscopy and simple abdomen X-ray after 3 hrs. After one week, the same procedure was repeated after ingestion of mosapride (5 mg for group 1, n = 8; 10 mg for group 2, n = 7) 15 min before the meal. Quantification of gastric residue by endoscopy was scored from 0 to 3, and the scores were added up. Results All subjects completed the study without any complication. The gastric emptying rate [T1/2 (min)] was in normal range (65.6 ± 12.6 min). Endoscopic gastric emptying was correlated significantly with gastric clearance of ROMs (r = 0.627, p = 0.012). Endoscopic gastric emptying and gastric clearance of ROMs after administration of mosapride showed significant differences in the 10 mg group (p < 0.05). Conclusion Endoscopy can evaluate gastric emptying safely and simply on an outpatient basis. A 10 mg dose of mosapride enhanced gastric emptying, assessed by both endoscopy and ROMs. PMID:20046511

Capsule retention in the small bowel is a known complication of small-bowel video capsule endoscopy. Surgery is the most frequently used method of capsule retrieval. To determine the incidence and causes of capsule retention and to describe double-balloon endoscopy (DBE) as the primary technique used for capsule retrieval. Retrospective analysis of all video capsule studies was performed at our center, and evaluation of the outcome of DBE was the first method used to retrieve entrapped video capsules. Tertiary referral center. A total of 904 patients who underwent small-bowel video capsule endoscopy. Capsule retrieval by DBE. The number of patients in whom capsule retention occurred and the number of patients in whom an entrapped capsule could be retrieved by using DBE. Capsule retention occurred in 8 patients (incidence 0.88%; 95% CI, 0.41%-1.80%) and caused acute small-bowel obstruction in 6 patients. All retained capsules were successfully removed during DBE. Five patients underwent elective surgery to treat the underlying cause of capsule retention. One patient required emergency surgery because of multiple small-bowel perforations. Retrospective design. In our series, the incidence of capsule retention was low. DBE is a reliable method for removing retained capsules and might prevent unnecessary surgery. If surgery is required, preoperative capsule retrieval allows preoperative diagnosis, adequate staging in case of malignancy, and optimal surgical planning. 2010 American Society for Gastrointestinal Endoscopy.

Clinical practice guidelines recommend video capsule endoscopy (VCE) studies in patients with iron-deficiency anemia (IDA) after conventional upper and lower endoscopies but there is a need for studies demonstrating the diagnostic yield, clinical impact, and cost in some patient subgroups. 1.To determine the diagnostic yield of VCE in premenopausal women with IDA compared with that in men and postmenopausal women. 2. To identify the presence of VCE predictors in premenopausal women. 3. To estimate the cost-clinical impact relationship associated with VCE in this indication. We retrospectively analyzed 408 patients who underwent VCE. Patients with IDA were enrolled (premenopausal, postmenopausal women, and men), with previous normal work-up by conventional endoscopies. A total of 249 patients were enrolled: 131 women (52.6%), of which 51 were premenopausal and 80 were post-menopausal, and 118 men. The mean age was 60.7±16 years. The diagnostic yield of VCE for the diagnosis of IDA was 44.6% (95% CI 39.9 - 50.8). Diagnostic yield was 50.8% vs 38.9% in men vs women (p=0.05) and was 55% vs 13.7% in postmenopausal vs premenopausal women (p<0.001). No predictors of small bowel lesions were found in premenopausal women. The most common findings in the postmenopausal group were angioectasias (70.5%) and erosions (57.1%) in the premenopausal group. The cost in premenopausal women was 44.727€ and 86.3% of the procedures had no clinical impact. The diagnostic yield of VCE is low in the etiological study of IDA in premenopausal women and there is no cost-effectiveness in relation to clinical impact. No predictors of small bowel lesions were found in this group. Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.

To evaluate whether and when Drug-Induced Sleep Endoscopy (DISE) changes diagnosis and treatment plan in pediatric Obstructive Sleep Apnoea Syndrome (OSAS) with the aim to identify specific subgroups of patients for whom DISE should be especially considered. A case-control study of DISE in 150 children with OSAS. Pre-operative OSA were assessed through detailed history, Chervin questionnaire, physical examination and overnight polysomnography. The group of study was divided into three subgroups according to clinical and polysomnographyc criteria: conventional OSAS, disproportional OSAS and persistent OSAS. Endoscopic evaluation of the upper airway during DISE was scored using Chan classification. Surgical treatment was tailored individually upon the basis of sleep endoscopy findings: performance of any surgery other than tonsillectomy and adenoidectomy (T&A) was considered as a change of the treatment plan. Cases and controls were compared considering presence and absence of DISE-directed extra surgery, respectively. 150 patients with mean age (SD) 56.09 (23.94) months and mean apnoea-hypopnea index (AHI) of 5.79 (6.52) underwent DISE. The conventional subgroup represented the 58.67% of the sample (n = 88), while the disproportional one counted for the 26.67% (n = 40), and the persistent one for 14.66% (n = 22) of the population. Sleep endoscopy changed the surgical plan in 4.5% of conventional OSAS, 17.5% of disproportional OSAS and 72.7% of persistent OSAS (p < 0.005). Overall, a change of the treatment plan operated by DISE was associated with a non-conventional OSAS status (OR = 6; 95% CI = 1.6-26.4). DISE is a safe procedure in children suffering from OSAS, and, despite being unnecessary in conventional cases of OSA, DISE should be considered not only in syndromic children, as previously demonstrated, but also in the general non-syndromic pediatric population, in the case of non-conventional OSA patients, and in children with persistent OSAS.

Laparoscopic Heller myotomy and fundoplication is considered today the treatment of choice for achalasia. The optimal treatment for end-stage achalasia with esophageal dilation is still controversial. This multicenter and retrospective study aims to evaluate the outcome of laparoscopic Heller myotomy in patients with a massively dilated esophagus. Eleven patients (mean age, 56 years; 6 men) with massively dilated esophagus (esophageal diameter greater than 10 cm) underwent a laparoscopic Heller myotomy and anterior fundoplication between 2000 and 2009 at three different institutions. Preoperative workup included upper endoscopy, esophagram, and esophageal manometry in all patients. Average follow-up was 31.5 months (range, 3 to 60 months). Two patients (18%) had severe dysphagia, four patients (36%) had mild and occasional dysphagia to solid food, and five patients (45%) were asymptomatic. All patients gained or kept body weight, except for the two patients with severe dysphagia. Of the two patients with severe dysphagia, one underwent esophageal dilatation and the other a laparoscopic esophagectomy. They are both doing well. Heller myotomy relieves dysphagia in the majority of patients even when the esophagus is massively dilated.

To study the relationship between esophageal motor functional disorder [decreased lower esophageal sphincter pressure (LESP)and ineffective motility (IEM)] and gastroesophageal reflux disease (GERD). Totally 89 patients with GERD were enrolled in this study. All of them underwent 24-hour pH monitoring with dual-channel probe and stationary esophageal manometry. In addition, 77 of these patients underwent upper endoscopy. IEM and LES, 10 mmHg were common disturbances in patients with GERD (54% and 48%, respectively). The number of the acid reflux events of distal esophagus and prevalence of moderate or severe erosive esophagitis (EE) were significantly higher in patients with low LESP and IEM than patients without low LESP ( P<0.05). The number of the acid reflux events in distal esophagus was significantly correlated with the severity of esophagitis, distal esophagus amplitude, and LESP, while no such correlation was found between IEM and degree of esophageal acid exposure or esophagitis. The pathophysiology of GERD is probably multifactorial. Lower LESP or IEM is not a independent pathophysiological factor for GERD. However,one single factor is insufficient to explain all the pathogenic mechanism of GERD.

According to a methodologic plan for determining sources and the diseases that originate chronic diarrhoea. In all patients hematologic, bioquimic, coprocultures, coproparasitologic exams were done, chest and intestinal transit X-rays. All underwent duodenal content culture. Colon X-ray in 25 cases; proctosigmoidoscopy in 14 and upper digestive endoscopy in 19 patients. Abdominal echography in 12 and TAC in 2 cases. The final results showed as determinant diseases for chronic diarrhoea, according to their frequency: enteroparasitosis (23.3%), functional digestive disorders (20.0%), intestinal bacterial overpopulation (15.5%) of unknown origin (8.8%), colon diverticulus (7.7%) proven and probably (5.5%), lactose intolerance (3.3%), diabetes mellitus (2.2%), and in one case (1.1%) the following: intestinal linfoma, pancreas malignancy, AIDS, colonic and deformation and megaloblastic anemia. The causes of chronic diarrhoea are several and multifactorals and in this study we prove the preeminence of the intestinal parasitosis, functional disorders and intestinal bacterial overpopulation and with less frequency other pathologies.

Upper non-variceal gastrointestinal bleeding - review the effectiveness of endoscopic hemostasis methods

PubMed Central

Szura, Mirosław; Pasternak, Artur

2015-01-01

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.

Esophageal stenosis is a severe complication in dystrophic epidermolysis bullosa (EB). Endoscopic dilations may cause mucosal injury with stricture recurrence. Our aim was to describe our referral EB-center experience on safety and long-term efficacy of fluoroscopically guided balloon dilation without endoscopy. Over 14 years, 34 patients with EB, previously evaluated with barium esophagogram for dysphagia, underwent balloon esophageal dilation. Under fluoroscopy, a guide wire was introduced via a nostril into the stomach. A 12-mm pneumatic balloon, which passed over the wire, was filled using radio-opaque contrast, dilating the stricture. Orotracheal intubation was avoided. Antibiotics, dexamethasone, and proton-pump inhibitors were administered. Study approval was obtained from our ethical board. Ninety-three dilations were performed. Seventeen patients had a single stenosis. The mean age of onset was 18 years (range, 3-47 years). Thirteen patients underwent one dilation. In 6 cases, endoscopy was necessary to visualize the esophageal lumen. Complications included cervical esophageal perforation (2) and transitory dysphagia (10). Thirty patients were feeding within 24 hours. During the follow-up, 2 patients required a gastrostomy, and 2 patients underwent fundoplication for gastroesophageal reflux disease. Fluoroscopically guided balloon dilation in EB is a safe and well-tolerated procedure. An experienced endoscopy team is necessary in certain cases. Copyright © 2011 Elsevier Inc.

Chronic gastroesophageal reflux disease (GERD) is a risk factor for Barrett's esophagus (BE), the most important surrogate marker for the development of esophageal adenocarcinoma (EAC). The need to document the presence of intestinal metaplasia in esophageal biopsies from a columnar lined esophagus (CLE) to diagnose BE is debated. The objective of this study was to prospectively evaluate the prevalence and risk factors of CLE in a large cohort of GERD patients undergoing upper endoscopy. Consecutive patients presenting to the endoscopy unit at a tertiary referral center for their index upper endoscopy for evaluation of GERD symptoms were enrolled in this prospective cohort study. Patients were asked to complete a validated GERD questionnaire that documents the onset of GERD symptoms (heartburn and acid regurgitation) and grades the frequency and severity of symptoms experienced over the past year. Demographic information, body mass index, and use of aspirin/nonsteroidal antiinflammatory drugs were recorded. Endoscopic details including length of CLE, presence and size of hiatal hernia were noted. Patients with CLE (cases) were compared with those without CLE (controls) using Fischer's exact test and t-test. All factors that were statistically significant (P<0.05) were then entered into stepwise logistic regression to evaluate for independent predictors of CLE. A total of 1058 patients with GERD symptoms were prospectively enrolled. On index endoscopy, the prevalence of CLE was 23.3%, whereas of CLE with documented intestinal metaplasia was 14.1%. On univariate analysis, male gender, Caucasian race, heartburn duration of >5 years, presence and size of hiatal hernia were significantly associated with the presence of CLE compared with controls (P<0.05). On multivariate analysis, heartburn duration >5 years (odds ratio (OR): 1.50, 95% confidence interval (CI): 1.07-2.09, P=0.01), Caucasian race (OR: 2.40, 95% CI: 1.42-4.03, P=0.001), and hiatal hernia (OR: 2.07, 95% CI: 1.50-2.87, P<0.01) were found to be independent predictors for CLE. CLE length was significantly associated with the presence of intestinal metaplasia (P<0.001). If BE is defined by the presence of CLE alone on upper endoscopy, up to 25% of GERD patients are diagnosed with this lesion. Enrolling all these patients in surveillance programs would have significant ramifications on health-care resources.

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

To determine the prevalence of Helicobacter pylori (H. pylori) infection and of various upper gastrointestinal (GI) lesions in HIV + patients with GI symptoms and the relation of H. pylori infection to CD4 cell counts. In all, 56 HIV + patients and 56 age- and sex-matched HIV - controls, all with upper GI symptoms, were evaluated by an upper endoscopy examination and gastric biopsy. H. pylori status was assessed with a urease test and histology. HIV was diagnosed with the rapid test and enzyme-linked immunosorbent assay (ELISA). The prevalence of H. pylori was 50% (28/56 [95%CI 36.3-63.7]) in HIV + subjects and 55% (31/56 [95%CI 41.5-68.7]) in HIV - controls (p = 0.57). H. pylori infection rates did not differ significantly in HIV + patients between those with a CD4 count ≥200/mm 3 (52%) and those with a CD4 count <200/mm 3 (42%) (p = 0.62). The prevalence on endoscopy of specific lesions in HIV + patients and controls were compared: esophageal candidiasis (61%, 34/56 vs. 7%; p<0.0001), esophageal ulcers (18%, 10/56 vs 2%; p = 0.01), corpus gastritis (41%; 23/56 vs 5%; p<0.0001), and duodenitis (20%, 11/56, vs 0%; p = 0.001). The prevalence rate of H. pylori did not differ significantly between HIV + and HIV - subjects. Prevalence of H. pylori was also lower, although not significantly, among HIV + patients with CD4 T-cell counts below 200/mm 3 . On endoscopy, esophageal candidiasis was the most common finding in HIV + patients, discovered by dysphagia.

Capsule endoscopy is widely used for diagnosis of small-bowel disease; however, the impact of capsule endoscopy on clinical management remains uncertain. We conducted a prospective study of the impact capsule endoscopy on clinical management decisions in 128 patients with suspected small-bowel pathology. Prior to performing each procedure the gastroenterologist predicted the findings of capsule endoscopy and further management based on the clinical history and previous investigations. This prediction was compared with the actual results of capsule endoscopy and the following investigative and therapeutic management. The actual findings of capsule endoscopy and the further management were consistent with clinical prediction in 93/128 patients (73 %) and, irrespective of capsule endoscopy findings, no further procedures were required in 80 % of these patients. In 13 patients (10 %), gastric or colonic pathology was discovered that had not been detected on prior gastroscopy or colonoscopy. Thus, capsule endoscopy findings in the small bowel changed clinical management in 22 patients (17 %). In 4 patients, positive findings on capsule endoscopy that had not been predicted by the examiner prompted referral for abdominal surgery. Conversely, planned surgery was canceled in four other patients. In this series of patients referred for capsule endoscopy, small-bowel findings and appropriate clinical management were predicted on clinical grounds alone in approximately three-quarters of patients. Repetition of standard upper and lower endoscopy may be useful in many patients prior to small-bowel imaging. Referral for capsule endoscopy should take into account whether the findings will impact on clinical management; however, capsule endoscopy is mandatory in patients in whom surgery for small-bowel bleeding is intended.

Comparison of drug-induced sleep endoscopy and Müller's maneuver in diagnosing obstructive sleep apnea using the VOTE classification system.

Knowledge of the site of obstruction and the pattern of airway collapse is essential for determining correct surgical and medical management of patients with Obstructive Sleep Apnea Syndrome (OSAS). To this end, several diagnostic tests and procedures have been developed. To determine whether drug-induced sleep endoscopy (DISE) or Müller's maneuver (MM) would be more successful at identifying the site of obstruction and the pattern of upper airway collapse in patients with OSAS. The study included 63 patients (52 male and 11 female) who were diagnosed with OSAS at our clinic. Ages ranged from 30 to 66 years old and the average age was 48.5 years. All patients underwent DISE and MM and the results of these examinations were characterized according to the region/degree of obstruction as well as the VOTE classification. The results of each test were analyzed per upper airway level and compared using statistical analysis (Cohen's kappa statistic test). There was statistically significant concordance between the results from DISE and MM for procedures involving the anteroposterior (73%), lateral (92.1%), and concentric (74.6%) configuration of the velum. Results from the lateral part of the oropharynx were also in concordance between the tests (58.7%). Results from the lateral configuration of the epiglottis were in concordance between the tests (87.3%). There was no statistically significant concordance between the two examinations for procedures involving the anteroposterior of the tongue (23.8%) and epiglottis (42.9%). We suggest that DISE has several advantages including safety, ease of use, and reliability, which outweigh MM in terms of the ability to diagnose sites of obstruction and the pattern of upper airway collapse. Also, MM can provide some knowledge of the pattern of pharyngeal collapse. Furthermore, we also recommend using the VOTE classification in combination with DISE.

To determine whether patients with no alarm signs who ask the endoscopist to shorten their waiting time due to test result anxiety, represent a risk category for a major organic pathology. At our open-access endoscopy service, we set up an expedite list for six months for outpatients who complained that the waiting time for gastroscopy was too long. Over this period we studied 373 gastroscopy patients. In addition to personal details, we collected information on the presence of Hp infection and compliance with dyspepsia guideline indications for gastroscopy. Average waiting time was 38.2 days (SD 12.7). The 66 patients who considered the waiting time too long underwent gastroscopy within 15 days. We made 5 diagnoses of esophageal and gastric tumour and gastric ulcer (7.6%) among the expedite list patients and 14 (4.6%) among those on the normal list (p=0.31). On including duodenal peptic disease in the analysis, the total prevalence rate rose to 19.7% in the short-wait group and to 10.4% (p=0.036) in the longer-wait group. Our data suggests that asking to be fast-tracked does not have prognostic impact on the diagnosis of a major (gastric ulcer and cancer) pathology.

We aimed to evaluate the prevalence of irritable bowel syndrome (IBS) in patients with typical reflux symptoms as distinguished into gastroesophageal reflux disease (GERD), hypersensitive esophagus (HE), and functional heartburn (FH) by means of endoscopy and multichannel intraluminal impedance (MII)-pH monitoring. The secondary aim was to detect pathophysiological and clinical differences between different sub-groups of patients with heartburn. Patients underwent a structured interview based on questionnaires for GERD, IBS, anxiety, and depression. Off-therapy upper-gastrointestinal (GI) endoscopy and 24 h MII-pH monitoring were performed in all cases. In patients with IBS, fecal calprotectin was measured and colonoscopy was scheduled for values >100 mg/kg to exclude organic disease. Multivariate logistic regression analysis was performed to identify independent risk factors for FH. Of the 697 consecutive heartburn patients who entered the study, 454 (65%) had reflux-related heartburn (GERD+HE), whereas 243 (35%) had FH. IBS was found in 147/454 (33%) GERD/HE but in 187/243 (77%) FH patients (P<0.001). At multivariate analysis, IBS and anxiety were independent risk factors for FH in comparison with reflux-related heartburn (GERD+HE). IBS overlaps more frequently with FH than with GERD and HE, suggesting common pathways and treatment. HE showed intermediate characteristic between GERD and FH.

Purpose. The aim of this study is to propose a simple and efficient combination surgery for the management of dacryocystitis with canalicular obstruction. Methods. A retrospective noncomparative case series of dacryocystitis with canalicular obstruction has been studied. Twelve patients with dacryocystitis and canalicular obstruction underwent a conventional endoscopic endonasal dacryocystorhinostomy (EE-DCR) combined with a modified canalicular repair. Postoperative observations included slit lamp, fluorescein dye disappearance test, lacrimal syringing, lacrimal endoscopy, and nasal endoscopy. Results. After 6-18 months of postoperative follow-up, the symptoms of epiphora and mucopurulent discharge disappeared completely in 10 patients, and occasional or intermittent epiphora remained in 2 patients. All of the twelve patients showed an opened intranasal ostium and normal fluorescein dye disappearance test. Patent bicanalicular irrigation was achieved in 9 patients. One patient had a partial and the other two had a complete reobstruction by lacrimal irrigation to their repaired lower canaliculus; however, all of them had a patent lacrimal irrigation to upper canaliculus. The functional success rate for the combination surgery is 83% (10/12), and anatomical success rate is 75% (9/12). Conclusion. EE-DCR combined with modified canalicular repair is a simple and efficient method for the management of dacryocystitis with canalicular obstruction.

A 43-year-old female patient presented with a chief complaint of upper abdominal pain. As her complaints had lasted for 1 month, an upper gastrointestinal system endoscopy was performed and discovered a bezoar in the stomach. The bezoar was quite hard and light green-yellow in color. Pathological examination revealed phytobezoar. The patient was hospitalized and given oral Coca-Cola(®) Zero for seven days at a dose of 500 mL three times daily. The upper gastrointestinal system endoscopy performed at the end of 7 days showed that the phytobezoar had softened and become smaller. The phytobezoar was broken into pieces with biopsy forceps and washing was applied, so the phytobezoar pieces could pass through the pylorus. The patient was discharged after the procedure without problem.

Endoscopic variceal ligation (EVL) is widely used to prevent esophageal variceal bleeding in patients with advanced cirrhosis. However, the safety and efficacy of EVL in this setting have not been clearly established. This study included 300 adult patients with cirrhosis on our liver transplant waitlist who underwent upper gastrointestinal endoscopy. Esophageal varices deemed to be at high risk of bleeding were banded until eradication or transplantation. A retrospective review of patient notes and endoscopy databases was undertaken, and the number of banding episodes, complications, and patient outcomes were recorded. Forty-two of 300 patients presented with or had previous variceal bleeding prior to referral and were excluded from the analysis. Of the remaining 258 patients, 101 underwent a total of 259 banding episodes (2.6 per patient) with a median follow-up post-banding of 18.4 months per patient (a total of 150 patient years). Failed prophylaxis occurred in 2 patients (2%), and there were 3 episodes (1.2%) of acute hematemesis from band-induced ulceration. One patient (1%) had mild esophageal stricturing post-banding without dysphagia. Four of 36 patients (11%) previously found to have moderately sized or larger varices that were not banded presented with hematemesis due to variceal bleeding and were subsequently banded. None of the patients that received banding died because of bleeding or failed to receive a transplant as a result of banding complications. This study shows that in liver transplant candidates, EVL is highly effective in preventing first variceal bleed. Although banding carries a small risk of band-induced bleeding, this rate is low in comparison with the predicted rate of variceal bleeding in this population.

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.

A 60-year-old woman underwent upper gastrointestinal endoscopy for an abnormality identified during routine examination. The lower gastric corpus showed a type 0-I elevated lesion with a faded mucosa and an area of converging mucosal folds in contact with the lesion. Biopsy indicated the former to be a high-grade adenoma and the latter to be a mucosa-associated lymphoid tissue (MALT) lymphoma. At the same time, Helicobacter pylori infection was diagnosed. Eradication therapy was administered to manage the MALT lymphoma; this resulted in improvement after 3 months. Endoscopic submucosal dissection was performed for the elevated lesion, and subsequent histopathology showed contact between the MALT lymphoma and gastric cancer. Therefore, the patient was diagnosed with a collision tumor. Concurrent cancers are increasingly reported and should be considered during examination.

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.

To evaluate, in a group of patients with long-standing type 1 diabetes (DM1), an association of dyspepsia symptoms with: changes in the gastroduodenal mucosa, infection by Helicobacter pylori, glycemic control, and psychological and nutritional factors. A total of 32 patient with DM1 were studied (age: 38 ± 9 years; females: 25; diabetes duration: 22 ± 5 years). All patients answered a standardized questionnaire for the evaluation of gastrointestinal symptoms and underwent upper gastrointestinal endoscopy, with gastric biopsies for the evaluation of Helicobacter pylori infection. The presence of anxiety and depression was evaluated by the HAD scale. Nutritional parameters were BMI, arm and waist circumference, skinfold measurement, and body fat percentage. Upper endoscopy detected lesions in the gastric mucosa in 34.4% of the patients, with similar frequency in those with (n = 21) and without dyspepsia (n = 11). The patients with dyspepsia complaints showed greater frequency of depression (60% vs. 0%; p = 0.001), higher values for HbA1c (9.6 ± 1.7 vs. 8.2 ± 1.3%; p = 0.01) and lower values for BMI (24.3 ± 4.1 vs. 27.2 ± 2.6 kg/m2; p = 0.02), body fat percentage (26.6 ± 6.2 vs. 30.8 ± 7.7%; p = 0.04), and waist circumference (78.7 ± 8 vs. 85.8 ± 8.1 cm; p = 0.02). No association was found between the symptoms and the presence of Helicobacter pylori. Dyspepsia symptoms in patients with long-standing DM1 were associated with glycemic control and depression, and they seem to negatively influence the nutritional status of these patients.

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.

Background Lymphocytic Esophagitis (LyE) is a recently described clinicopathological condition, but little is known about its features and clinical associations. Aim To characterize patients with LyE, compare them to non-LyE controls, and identify risk factors. Methods We conducted a retrospective study of all patients ≥18 years old who underwent upper endoscopy with esophageal biopsy between January 1, 2000 and June 1, 2012. Archived pathology slides were re-reviewed and LyE was diagnosed if there was lymphocyte-predominant esophageal inflammation with no eosinophils or granulocytes. Three non-LyE controls groups were also defined: reflux, eosinophilic esophagitis (EoE), and normal. Clinical data were extracted from electronic medical records, and LyE cases were compared to non-LyE controls. Results 27 adults were diagnosed with LyE, and the majority were female (63%). The most common symptom was dysphagia (70%). 52% had a prior or current diagnosis of reflux. Endoscopic findings included strictures (37%), erosive esophagitis (33%), rings (26%), and hiatal hernia (26%); 33% of patients required dilation. After histology re-review, 78% of LyE patients were found to have more than 20 lymphs/hpf. In comparison to the normal, reflux and EoE controls, patients with LyE tended to be non-white (p<0.01), were more commonly tobacco users (p=0.02), and less likely to have seasonal allergies (p=0.02). Conclusion LyE commonly presents with dysphagia due to esophageal strictures which require dilation. Smoking was associated with LyE whereas atopy was not. LyE should be considered as a diagnostic possibility in patients with these characteristics undergoing upper endoscopy. PMID:27343035

Clinical data were extracted from electronic medical records, and LyE cases were compared to non-LyE controls. Twenty-seven adults were diagnosed with LyE, and the majority were female (63 %). The most common symptom was dysphagia (70 %). Fifty-two percentage had a prior or current diagnosis of reflux. Endoscopic findings included strictures (37 %), erosive esophagitis (33 %), rings (26 %), and hiatal hernia (26 %); 33 % of patients required dilation. After histology re-review, 78 % of LyE patients were found to have more than 20 lymphs/hpf. In comparison with the normal, reflux and EoE controls, patients with LyE tended to be nonwhite (p < 0.01), were more commonly tobacco users (p = 0.02) and less likely to have seasonal allergies (p = 0.02). LyE commonly presents with dysphagia due to esophageal strictures which require dilation. Smoking was associated with LyE, whereas atopy was not. LyE should be considered as a diagnostic possibility in patients with these characteristics undergoing upper endoscopy.

In some patients, obstructive sleep apnea (OSA) can be resolved with improvement in pharyngeal patency by sleeping lateral rather than supine, possibly as gravitational effects on the tongue are relieved. Here we tested the hypothesis that the improvement in pharyngeal patency depends on the anatomical structure causing collapse, with patients with tongue-related obstruction and epiglottic collapse exhibiting preferential improvements. Twenty-four OSA patients underwent upper airway endoscopy during natural sleep to determine the pharyngeal structure associated with obstruction, with simultaneous recordings of airflow and pharyngeal pressure. Patients were grouped into three categories based on supine endoscopy: Tongue-related obstruction (posteriorly located tongue, N = 10), non-tongue related obstruction (collapse due to the palate or lateral walls, N = 8), and epiglottic collapse (N = 6). Improvement in pharyngeal obstruction was quantified using the change in peak inspiratory airflow and minute ventilation lateral versus supine. Contrary to our hypothesis, patients with tongue-related obstruction showed no improvement in airflow, and the tongue remained posteriorly located while lateral. Patients without tongue involvement showed modest improvement in airflow (peak flow increased 0.07 L/s and ventilation increased 1.5 L/min). Epiglottic collapse was virtually abolished with lateral positioning and ventilation increased by 45% compared to supine position. Improvement in pharyngeal patency with sleeping position is structure specific, with profound improvements seen in patients with epiglottic collapse, modest effects in those without tongue involvement and-unexpectedly-no effect in those with tongue-related obstruction. Our data refute the notion that the tongue falls back into the airway during sleep via gravitational influences. © Sleep Research Society 2017.

The diagnosis of gastro-oesophageal reflux disease (GERD) remains a challenge as both invasive methods and symptom-based strategies have limitations. The symptom-based management of GERD in primary care may be further optimised with the use of a questionnaire. To assess the diagnostic validity of the GerdQ questionnaire in patients with symptoms suggestive of GERD. Patients with symptoms suggestive of GERD without alarm features, underwent upper endoscopy, and if normal, pH-metry. Patients were followed for 4 weeks and GerdQ was completed blinded to the investigator at both visits. Reflux oesophagitis or pathological acid exposure was used as diagnostic references for GERD. The diagnostic accuracy for GERD on symptom response to proton pump inhibitor (PPI) was assessed. Among the 169 patients, a GerdQ cutoff ≥9 gave the best balance with regard to sensitivity, 66% (95% CI: 58-74), and specificity, 64% (95% CI: 41-83), for GERD. The high prevalence of reflux oesophagitis (81%) resulted in a high proportion of true positives, but at the same time a high proportion of false-negatives. Consequently, GerdQ had a high positive predictive value, 92% (95% CI: 86-97), but a low negative predictive value, 22% (95% CI: 13-34), for GERD. Symptom resolution on PPI therapy had high sensitivity, 76% (95% CI: 66-84), but low specificity, 33% (95% CI: 17-53), for GERD. GerdQ is a useful complementary tool for the diagnosis of gastro-oesophageal reflux disease in primary care. The implementation of GerdQ could reduce the need for upper endoscopy and improve resource utilisation. Symptom resolution on proton pump inhibitor did not predict gastro-oesophageal reflux disease. © 2013 Blackwell Publishing Ltd.

Gastro-oesophageal reflux disease (GORD) is 'a condition which develops when the reflux of gastric content causes troublesome symptoms or complications'. Instrumental diagnostic tests generally used for GORD are 24-hour pH-metry and upper gastrointestinal (GI) endoscopy but barium study associated with provocative manoeuvres such as the water-siphon test (WST), has also been used for GORD. The aim of this paper was to estimate the accuracy of several tests in patients with GORD in a tertiary care setting, focusing on WST, which is rapid and non-invasive, simple to perform and well-tolerated by patients. A total of 172 consecutive patients, symptomatic for reflux referred to a tertiary medical centre, were considered and data regarding the WST, 24-hour pH-metry, upper GI endoscopy with histology were analysed using latent class analysis, a multivariable statistical method for estimating the accuracy of tests when a gold standard is not available. The overall proportion of GORD in the sample was estimated at 0.664 [95% confidence interval (CI) = (0.589; 0.731)]. WST proved to be the most sensitive [Se = 0.886; 95% CI = (0.688; 1.000)] compared with pH-metry [Se = 0.620; 95% CI = (0.493; 0.745)] and endoscopy with histology [Se = 0.534; 95% CI = (0.273; 0.789)]. It was less specific [Sp = 0.537; 95% CI = (0.003; 1.000)] than pH-metry [Sp = 0.547; 95% CI = (0.281; 0.813)], and even less than endoscopy with histology [Sp = 0.862; 95% CI = (0.495; 1.00)]. Positive predictive values were estimated at 0.792 [95% CI = (0.721; 0.862)] for WST, 0.731 [95% CI = (0.643; 0.819)] for pH-metry and 0.886 [95% CI = (0.811; 0.961)] for endoscopy with histology. Negative predictive values were estimated at 0.707 [95% CI = (0.573; 0.841)] for WST, 0.422 [95% CI = (0.310; 0.534)] for pH-metry and 0.484 [95% CI = (0.387; 0.581)] for endoscopy with histology. Water-siphon test might possibly be useful in patients with suspected GORD because it is highly sensitive and predictive. A positive outcome of the WST associated with a barium study can certainly justify upper GI endoscopy and support any pharmacological treatment of GORD.

Acute upper gastrointestinal bleeding (AUGIB) results in 25 000 hospital admissions annually. Patients admitted at weekends with AUGIB have increased mortality, and guidelines advise out-of-hours endoscopy. We present retrospective data from our service involving the interhospital transfer of patients. We pooled resources of two neighbouring general hospitals, just north of London. Emergency endoscopy is performed at the start of the list followed by elective endoscopy in the endoscopy unit on Saturday and Sunday mornings. From Friday evening to Sunday morning, patients admitted to Queen Elizabeth II Hospital (QEII) are medically stabilised and transferred to Lister Hospital by ambulance. 240 endoscopies were performed out of hours from December 2007 to March 2011. Of these, 54 patients were transferred: nine had emergency endoscopy at QEII as they were medically unstable; eight of the patients transferred required therapeutic intervention for active bleeding. The mean pre-endoscopy Rockall score of those transferred was 2.5. We examined the records of 51 of the 54 patients transferred. There were three deaths within 30 days after endoscopy not associated with the transfer process. 19 (37%) patients had reduced hospitalisation after having their endoscopy at the weekend. The introduction of the out-of-hours endoscopy service in our trust has had multiple benefits, including patients consistently receiving timely emergency endoscopy, significantly reduced disruption to emergency operating theatres, and participation of endoscopy nurses ensures a better and safer experience for patients, and better endoscopy decontamination. We suggest our model is safe and feasible for other small units wishing to set up their own out-of-hours endoscopy service to adopt.

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.

During endoscopy of the esophagus fluorescence images were recorded at a delay of 20 ns after pulsed laser excitation simultaneously with conventional reflected white light images. To label malignant cells (dysplasia, tumor) 5-aminolaevulinic acid was applied prior to fluorescence guided bi-opsy. In this way pre-malignant and malignant lesions were detected not seen previously during routine endoscopy.

Background A 43-year-old female patient presented with a chief complaint of upper abdominal pain. As her complaints had lasted for 1 month, an upper gastrointestinal system endoscopy was performed and discovered a bezoar in the stomach. Case presentation The bezoar was quite hard and light green-yellow in color. Pathological examination revealed phytobezoar. The patient was hospitalized and given oral Coca-Cola® Zero for seven days at a dose of 500 mL three times daily. Conclusion The upper gastrointestinal system endoscopy performed at the end of 7 days showed that the phytobezoar had softened and become smaller. The phytobezoar was broken into pieces with biopsy forceps and washing was applied, so the phytobezoar pieces could pass through the pylorus. The patient was discharged after the procedure without problem. PMID:22393302

To evaluate the type, frequency, and severity of macroscopic small bowel mucosal injury after chronic NSAID intake as assessed by capsule endoscopy (CE), as well as to correlate the severity of gastroduodenal and intestinal damage in these patients. A prospective, endoscopist-blind, controlled trial. Sixteen patients (14F/2M; age: 57.06 +/- 10.16 yrs) with osteoarthritis (OA) on chronic therapy with NSAIDs underwent CE and upper gastrointestinal endoscopy (UGE). Seventeen patients with OA (9F/2M; age: 57.47 +/- 9.82 yrs) who did not take NSAIDs were included as a control group. A scale ranging from 0 to 2 (0 = no lesions, 1-minor = red spots or petechiae, denuded areas and/or 1-5 mucosal breaks; 2-major = > 5 mucosal breaks and/or strictures, or hemorrhage) was designed to assess the severity of small bowel mucosal injuries. CE found intestinal lesions in 75% (12/16) of patients in the study group and in 11.76% (2/17) of controls (p < 0.01). Seven out of 16 NSAID consumers (43.75%) and none in the control group (0%) had a major small bowel mucosal injury (p < 0.01). The percentages of patients with grade 1 and 2 gastroduodenopathy in the study group, as assessed by UGE, were 37.14 and 23.81%, respectively. There was no significant difference in the rate of major enteropathy between patients with none or minor gastroduodenal injury, and those with major gastroduodenopathy (43.75 vs. 40%; p = N.S.). Chronic NSAID intake is associated with a high rate of small bowel mucosal injuries. Our data have failed to demonstrate a relationship between the severity of gastroduodenal and intestinal injury.

Helicobacter pylori (Hp) infection is mainly acquired during childhood; it is recognised as a cause of gastritis and peptic ulcer and it has been classified as a group A carcinogen by World Health Organization. The exact mode of transmission is as yet, not known. Aim of our study has been to identify risk factors associated with Helicobacter pylori infection in a preschool and school population and to confirm if Hp antigen in faeces is useful as screening in epidemiological studies. We interviewed, with questionnaire, 400 children (203 male; age range 3-10 years; mean age 6 years) of 3 different schools and stool samples were collected of all children too. 35 of 400 (8%) children underwent to upper gastrointestinal endoscopy because of a suspect of upper gastrointestinal disease. stool were collected from 400 school children and 35 of them shown positivity of Hp antigen test. A questionnaire about presence of nausea, vomit, recurrent abdominal pain, family size, parent's occupations and education, use of antibiotics, country of birth of child and parents, personal hygiene, breast feeding, presence of the animals was completed. 35 children with positive Hp stool antigen test and a suspicious of upper gastrointestinal disease (recurrent abdominal pain, diurnal or nocturnal abdominal pain, nausea, vomiting, iron deficiency) underwent to esophagogastroduodenoscopy (EGDS) that demonstrated antral gastritis and positive histology and urease rapid test. the results of this study suggest that risk factors for Hp infection are low socioeconomics factors, hygiene and living conditions and that Hp antigen in faeces is useful as screening test.

Candida esophagitis in an immunocompetent pregnant woman.

Nausea and vomiting are common during the first half of pregnancy and usually require only supportive measures. When symptoms are progressive and weight loss occurs, treatable causes should be sought by means of upper gastrointestinal endoscopy. We report a case of an immunocompetent gravida with invasive Candida albicans esophagitis. The immunocompetent primigravida developed progressive nausea, vomiting, epigastric pain, and a 4.1 kg weight loss during the second trimester of pregnancy. Treatment with metoclopramide and cimetidine for presumed gastroesophageal reflux was not effective. The patient had normal T-cell CD4 and CD8 subsets and was human immunodeficiency virus (HIV) antibody negative. Upper gastrointestinal endoscopy revealed C. albicans esophagitis which was treated with oral nystatin. The esophagitis had resolved completely when reassessed postpartum. The use of histamine(2) blockers is associated with an increased risk for fungal esophagitis and may have been a contributing cause in this case. Pregnant patients with persistent nausea, vomiting, and weight loss should be evaluated by endoscopy for fungal esophagitis.

Laparoscopic sleeve gastrectomy is a safe and effective bariatric operation, but postoperative reflux symptoms can sometimes necessitate revisional surgery. Roux-en-Y gastric bypass is the preferred operation in morbidly obese patients with gastro-oesophageal reflux disease. In 2011, we introduced preoperative endoscopy to assess for hiatus hernia or evidence of oesophagitis in conjunction with an assessment of gastro-oesophageal reflux symptoms for all patients undergoing bariatric surgery with a view to avoid sleeve gastrectomy for these patients. A prospectively maintained database was used to identify patients who underwent sleeve gastrectomy before and after we changed the unit policy. The need for revisional surgery in patients with troublesome gastro-oesophageal reflux disease was examined. Prior to 2011, 130 patients underwent sleeve gastrectomy, and 11 (8.5%) of them required conversion to Roux-en-Y gastric bypass for symptomatic reflux disease. Following the policy change, 284 patients underwent sleeve gastrectomy, and to date, only five (1.8%) have required revisional surgery (p = 0.001). Baseline demographics were comparable between the groups, and average follow-up period was 47 and 33 months, respectively, for each group. Preoperative endoscopy and a detailed clinical history regarding gastro-oesophageal reflux symptoms may improve patient selection for sleeve gastrectomy. Avoiding sleeve gastrectomy in patients with reflux disease and/or hiatus hernia may reduce the incidence of revisional surgery. © 2016 World Obesity.

Esophageal foreign body retrieval is typically performed by rigid or flexible esophagoscopy. Despite evidence supporting the efficacy and safety of balloon extraction, it is rarely performed. We sought to establish the financial benefits of this minimally invasive approach. A retrospective review of 241 children with esophageal coins between 2011 and 2013 was performed. Coins were removed via endoscopy or fluoroscopic-guided balloon retrieval. Timing, symptoms, facility cost, and patient charges were compared. Two hundred patients had attempted balloon retrieval with 80% success. Forty-one patients went directly for operative removal. Patients with respiratory difficulty (p=0.05), wheezing (p<0.01), or fever (p=0.03) were more often taken directly for endoscopic retrieval. The median cost and charges for attempted balloon extraction were $484 and $1647. The median cost and charges for primary endoscopy were $1834 and $6746. The median total cost and charges of attempted balloon extraction including ED, OR, transport, admission, and balloon retrieval were $1231 and $3539 versus $3615 and $12,204 in the primary endoscopy group (p<0.001, p<0.001). Seventeen percent of patients who underwent attempted balloon retrieval were admitted prior to removal compared to 76% who underwent primary endoscopy (p<0.001). Fluoroscopic guided balloon extraction of esophageal coins is a financially prudent choice which shortens hospital stay. III. Retrospective treatment and economic study.

Hydes, Theresa; Hansi, Navjyot; Trebble, Timothy M

Upper gastrointestinal (UGI) endoscopy is a routine healthcare procedure with a defined patient pathway. The objective of this study was to redesign this pathway for unsedated patients using lean thinking transformation to focus on patient-derived value-adding steps, remove waste and create a more efficient process. This was to form the basis of a pathway template that was transferrable to other endoscopy units. A literature search of patient expectations for UGI endoscopy identified patient-derived value. A value stream map was created of the current pathway. The minimum and maximum time per step, bottlenecks and staff-staff interactions were recorded. This information was used for service transformation using lean thinking. A patient pathway template was created and implemented into a secondary unit. Questionnaire studies were performed to assess patient satisfaction. In the primary unit the patient pathway reduced from 19 to 11 steps with a reduction in the maximum lead time from 375 to 80 min following lean thinking transformation. The minimum value/lead time ratio increased from 24% to 49%. The patient pathway was redesigned as a 'cellular' system with minimised patient and staff travelling distances, waiting times, paperwork and handoffs. Nursing staff requirements reduced by 25%. Patient-prioritised aspects of care were emphasised with increased patient-endoscopist interaction time. The template was successfully introduced into a second unit with an overall positive patient satisfaction rating of 95%. Lean thinking transformation of the unsedated UGI endoscopy pathway results in reduced waiting times, reduced staffing requirements and improved patient flow and can form the basis of a pathway template which may be successfully transferred into alternative endoscopy environments with high levels of patient satisfaction.

The aim of the present study was to determine whether high-definition endoscopy (HD) plus equipped with the iScan function or chromoendoscopy with Lugol's solution might permit the differentiation of NERD patients from those without reflux symptoms, proven by targeted biopsies of endoscopic lesions. A total of 100 patients without regular intake of proton pump inhibitors and with a normal conventional upper endoscopy were prospectively divided into NERD patients and controls. A second upper endoscopy was performed using HD+ with additional iScan function and then Lugol's solution was applied. Biopsy specimens were taken from the gastroesophageal junction in all patients. A total of 65 patients with reflux symptoms and 27 controls were included. HD(+) endoscopy with iScan revealed subtle mucosal breaks in 52 patients; the subsequent biopsies confirmed esophagitis in all cases. After Lugol's solution, 58 patients showed mucosal breaks. Sensitivity for the iScan procedure was 82.5%, whereas that for Lugol's solution was 92.06%. Excellent positive predictive values of 100% and 98.3%, respectively, were noted. The present study suggests that the majority of patients with NERD and typical symptoms of reflux disease can be identified by iScan or Lugol's chromoendoscopy as minimal erosive reflux disease (ERD) patients. © 2014 International Society for Diseases of the Esophagus.

How to Improve the Quality of Screening Endoscopy in Korea: National Endoscopy Quality Improvement Program.

Cho, Yu Kyung

2016-07-01

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.

To evaluate the results of combined multilevel surgery with transoral robotic surgery (TORS) in patients with obstructive sleep apnea/hypopnea syndrome for multilevel upper airway obstruction. Subjects who underwent combined sleep surgery via TORS were evaluated. The drug-induced sleep endoscopy was used in diagnosing the presence of level-specific upper airway collapse and to detect the type of surgery. Pre- and postoperative Apnea-hypopnea index, Epworth sleepiness scale lowest oxygen saturation, total operation time, robotic set-up time and robotic surgery time, blood loss value, and complications were recorded. Twenty five subjects were identified. All subjects underwent base of tongue (BOT) + epiglottoplasty. The tracheotomy was not performed for any patient. Overall, 72% of patients met the criteria for cure, 8% met the criteria for cure, and 20% of patients met the criteria for failure. There was a significant decrease between preoperative and postoperative Apnea-hypopnea index scores (28.7 ± 17.8 SD versus 9.4 ± 12.4, P = 0.000) and Epworth sleepiness scale scores (13.5 ± 2.8 versus 3.4 ± 1.6, P = 0.000). There was a significant increase between preoperative and postoperative ED SPO2 levels (80.7 ± 7.6 versus 82.6 ± 18.1, P = 0.001). TORS BOT, epiglottoplasty, and multilevel procedures in patients with obstructive sleep apnea/hypopnea syndrome can be regarded as feasible, safe, and effective technique.

The aim of this study is to evaluate the efficacy and viability of hypnosis before and during a gastrointestinal endoscopy. Six Gastroscopies and 22 colonoscopies were carried out under hypnosis in a group of patients. The patients ranged in age from 20 and 67 years and have a history of previously incomplete and poorly tolerated examinations or expressed an active demand for sedation. For 6 of the patients who underwent a gastroscopy under hypnosis, the procedure was successfully completed, reaching the second part of the duodenum without difficulty for the endoscopist. Colonoscopy of the cecum was completed in 19 of 20 patients. All patients, except 1, considered their tolerance level as "good." Hypnosis facilitated an adequate endoscopy intervention without any discomfort in 85% of the cases examined. Avoidance of anaesthesia reduces risk to the patient. Hence, hypnosis for gastrointestinal endoscopy appears to provide a promising strategy.

There have been few reports concerning the endoscopic removal of impacted esophageal foreign bodies from patients. The objective of this study was to evaluate the effectiveness of dual-channel endoscopy in managing foreign-body ingestions in patients. A total of 19 patients with foreign-body ingestions between September 2008 and July 2011 were selected from the Digestive Endoscope Center in Lishui, a typical middle-sized city in China. The patients underwent endoscopy following admission. The impacted foreign bodies were successfully removed from 18 patients without complications using a dual-channel endoscope. One patient underwent surgery for an ingested denture following the failure of the endoscopic removal method. This study demonstrates that dual-channel endoscopic management may be a useful option for removing ingested foreign bodies from the esophagus. PMID:23935752

After gastrectomy or esophagectomy, esophagogastrostomy and esophagojejunostomy are commonly used for reconstruction. Water-soluble contrast swallow is often used as a routine screening to exclude anastomotic leakage during the first postoperative week. In this retrospective study, the sensitivity and specificity of oral water-soluble contrast swallow for the detection of anastomotic leakage and its clinical symptoms were analysed. Records of 104 consecutive total gastrectomies and distal esophagectomies were analysed. In all cases, upper gastrointestinal contrast swallow with the use of a water-soluble contrast agent was performed on the 5 th postoperative day. Extravasation of the contrast agent was defined as anastomotic leakage. When anastomotic insufficiency was suspected but no extravasation was present, a computed tomography (CT) scan and upper endoscopy were performed. Oral contrast swallow detected 7 anastomotic leaks. Based on CT-scans and upper endoscopy, the true number of anastomotic leakage was 15. The findings of the oral contrast swallow were falsely positive in 4 and falsely negative in 12 patients, respectively. The sensitivity and specificity of the oral contrast swallow was 20% and 96%, respectively. Routine radiological contrast swallow following total gastrectomy or distal esophagectomy cannot be recommended. When symptoms of anastomotic leakage are present, a CT-scan and endoscopy are currently the methods of choice.

Acute upper gastrointestinal bleeding is a rare, but serious complication of gastric bypass surgery. The inaccessibility of the excluded stomach restrains postoperative examination and treatment of the gastric remnant and duodenum, and represents a major challenge, especially in the emergency setting. A 59-year-old patient with previous history of peptic ulcer disease had an upper gastrointestinal bleeding from a duodenal ulcer two years after having a gastric bypass procedure for morbid obesity. After negative upper endoscopy finding, he was urgently evaluated for gastrointestinal bleeding. At emergency laparotomy, the bleeding duodenal ulcer was identified by intraoperative endoscopy through gastrotomy. The patient recovered well after surgical hemostasis, excision of the duodenal ulcer and completion of the remnant gastrectomy. Every general practitioner, gastroenterologist and general surgeon should be aware of growing incidence of bariatric operations and coherently possible complications after such procedures, which modify patient's anatomy and physiology.

Pseudoaneurysm is a life-threatening complication after pancreaticoduodenectomy. An endovascular covered stent was employed for treatment of pseudoaneurysm of the common hepatic artery after pancreaticoduodenectomy. A 77-year-old female underwent pylorus-preserving pancreaticoduodenectomy for lower bile duct cancer. She complained of hematochezia but upper gastrointestinal endoscopy did not find a bleeding source. Angiography was performed and pseudoaneurysm of the common hepatic artery was discovered. Since no collateral perfusion to the liver was detected, embolization of the common hepatic artery was considered to expose the patient to the danger of severe hepatic dysfunction. Successful exclusion of the pseudoaneurysm was completed with an endovascular covered stent. Inflow of the hepatic artery was secured and no hepatic dysfunction developed. Patency of the stent was confirmed at 5 months follow-up. An endovascular covered stent can be a feasible modality for selected cases of the hepatic arterial pseudoaneurysm.

A 65-year-old man underwent a thromboexclusionoperation for management of chronic Stanford type B dissecting aneurysmin 1991. However, long-term follow-up CT scans after the operation revealed that the ascending aorta gradually enlarged and was eventually complicated by recurrent aortic dissection. The patient complained of frequent bloody sputum, whereas chest roentogenography showed no pulmonary abnormalities. Subsequent swallow esophagogram demonstrated that the upper esophagus was deviated to the right and the middle esophagus was greatly compressed by the aortic clamp. Esophageal endoscopy showed a bloody inner surface and marked swelling of the middle esophagus. The patient eventually died of massive hematemesis in 2001.more » We describe the imaging features of unanticipated complications such as recurrent dissecting aneurysm or impending esophageal rupture.Furthermore, we discuss the cause of hematemesis and document that the aortic clamp migrated and resulted in development of a recurrent aneurysmal dissection, which in turn resulted in esophageal rupture with aneurysmal disruption.« less

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.

It is known that at least 90% of duodenal ulcers are caused by infection with the bacterium Helicobacter pylori. Eradicating this organism usually results in complete resolution of the disease (Rosengren, Br J Gen Pract 46(409):491-492, 1996). To study the different changes if any in stomach wall at sites other than the ulcer in chronic duodenal ulcer patients by upper Gastro-Intenstinal Endoscopy followed by histopathological examination of different parts of stomach. This study was a retrospective study conducted in the Department of General surgery, V.S.S. Medical College, Burla, Sambalpur, odisha during the period of June 2007 to May 2009. Subjects were patients with chronic duodenal ulcer who underwent endoscopic examination, gastric biopsy and rapid urease test. Chronic gastritis of antrum, followed by erythematous pangastritis was the prominent feature both in endoscopy and histopathological examination. The Inflammatory change affected the mucosa and submucosa of the stomach wall. The prevalence rate of Helicobacter pylori was 84%, the antrum being the most common affected part (84%) followed by gastric fundus (41%). Chronic superficial atrophic gastritis of antrum, followed by pangastritis is the most common pathological abnormality in stomach wall in CDU cases. Gastric antrum is the most common site for H. pylori colonization followed by fundus. Presence of H. pylori in stomach wall is associated with active on chronic gastritis.

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.

Background Symptom-based surveys suggest that the prevalence of gastrointestinal diseases is lower in China than in Western countries. The aim of this study was to validate a methodology for the epidemiological investigation of gastrointestinal symptoms and endoscopic findings in China. Methods A randomized, stratified, multi-stage sampling methodology was used to select 18 000 adults aged 18-80 years from Shanghai, Beijing, Xi'an, Wuhan and Guangzhou. Participants from Shanghai were invited to provide blood samples and undergo upper gastrointestinal endoscopy. All participants completed Chinese versions of the Reflux Disease Questionnaire (RDQ) and the modified Rome II questionnaire; 20% were also invited to complete the 36-item Short Form Health Survey (SF-36) and Epworth Sleepiness Scale (ESS). The psychometric properties of the questionnaires were evaluated statistically. Results The study was completed by 16 091 individuals (response rate: 89.4%), with 3219 (89.4% of those invited) completing the SF-36 and ESS. All 3153 participants in Shanghai provided blood samples and 1030 (32.7%) underwent endoscopy. Cronbach's alpha coefficients were 0.89, 0.89, 0.80 and 0.91, respectively, for the RDQ, modified Rome II questionnaire, ESS and SF-36, supporting internal consistency. Factor analysis supported construct validity of all questionnaire dimensions except SF-36 psychosocial dimensions. Conclusion This population-based study has great potential to characterize the relationship between gastrointestinal symptoms and endoscopic findings in China. PMID:19925662

2016-01-01

Most researchers believe that the presence of large epiphrenic diverticulum (ED) with severe symptoms should lead to the consideration of surgical options. The choice of minimally invasive techniques and whether Heller myotomy with antireflux fundoplication should be employed after diverticulectomy became points of debate. The aim of this study was to describe how to perform laparoscopic transhiatal diverticulectomy (LTD) and oesophagomyotomy with the aid of intraoperative gastrointestinal (GI) endoscopy and how to investigate whether the oesophagomyotomy should be performed routinely after LTD. From 2008 to 2013, 11 patients with ED underwent LTD with the aid of intraoperative GI endoscopy at our department. Before surgery, 4 patients successfully underwent oesophageal manometry: Oesophageal dysfunction and an increase of the lower oesophageal sphincter pressure (LESP) were found in 2 patients. There were 2 cases of conversion to an open transthoracic procedure. Six patients underwent LTD, Heller myotomy and Dor fundoplication; and 3 patients underwent only LTD. The dysphagia and regurgitation 11 patients experienced before surgery improved significantly. Motor function studies showed that there was no oesophageal peristalsis in 5 patients during follow-up, while 6 patients showed seemingly normal oesophageal motility. The LESP of 6 patients undergoing LTD, myotomy and Dor fundoplication was 16.7 ± 10.2 mmHg, while the LESPs of 3 patients undergoing only LTD were 26 mmHg, 18 mmHg and 21 mmHg, respectively. In 4 cases experiencing LTD, myotomy and Dor fundoplication, the gastro-oesophageal reflux occurred during the sleep stage. LTD constitutes a safe and valid approach for ED patients with severe symptoms. As not all patients with large ED have oesophageal disorders, according to manometric and endoscopic results, surgeons can categorise and decide whether or not myotomy and antireflux surgery after LTD will be conducted.

To determine whether improper high-level disinfection practices during endoscopy procedures resulted in bloodborne viral infection transmission.  Retrospective cohort study.  Four Veterans Affairs medical centers (VAMCs).  Veterans who underwent colonoscopy and laryngoscopy (ear, nose, and throat [ENT]) procedures from 2003 to 2009.  Patients were identified through electronic health record searches and serotested for human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B virus (HBV). Newly discovered case patients were linked to a potential source with known identical infection, whose procedure occurred no more than 1 day prior to the case patient's procedure. Viral genetic testing was performed for case/proximate pairs to determine relatedness.  Of 10,737 veterans who underwent endoscopy at 4 VAMCs, 9,879 patients agreed to viral testing. Of these, 90 patients were newly diagnosed with 1 or more viral bloodborne pathogens (BBPs). There were no case/proximate pairings found for patients with either HIV or HBV; 24 HCV case/proximate pairings were found, of which 7 case patients and 8 proximate patients had sufficient viral load for further genetic testing. Only 2 of these cases, both of whom underwent laryngoscopy, and their 4 proximates agreed to further testing. None of the 4 remaining proximate patients who underwent colonoscopy agreed to further testing. Mean genetic distance between the 2 case patients and 4 proximate patients ranged from 13.5% to 19.1%.  Our investigation revealed that exposure to improperly reprocessed ENT endoscopes did not result in viral transmission in those patients who had viral genetic analysis performed. Any potential transmission of BBPs from colonoscopy remains unknown.

Efficacy of PPI, levofloxacin and amoxicillin in the eradication of Helicobacter pylori compared to conventional triple therapy at a Venezuelan hospital.

Helicobacter pylori is the main cause of gastritis, gastroduodenal ulcers and gastric cancer. In the past two decades, the recommended treatment for its eradication as a first-line regimen is the standard triple therapy consisting of a proton pump inhibitor (PPI), amoxicillin and clarithromycin or metronidazole. However, the effectiveness of this traditional regime, which initially was 90%, progressively declined in many parts of the world and is currently 57-73%. The aim of this study was to evaluate whether the eradication rate with triple therapy with levofloxacin is superior as first-line therapy to that with treatment using clarithromycin in the population that attended as outpatients at the Hospital of Lídice. We designed a prospective study, with two groups of patients presenting dyspeptic symptoms, from October 2010 to October 2011, who underwent upper gastrointestinal endoscopy and whose biopsies were positive for infection with H. pylori. At the end, 81 patients were included in the order of biopsy result arrival to fill the quota of each group. The first group with 42 patients underwent triple therapy with clarithromycin and the second group with 39 patients underwent therapy with levofloxacin, amoxicillin and a PPI. The patients' age ranged between 23 and 76years, the average being 49.5. The predominant sex was female, at 72.84%. Both treatments lasted for 10days and the patients were clinically re-evaluated 15days after their conclusion and programmed for a second endoscopy to verify H. pylori eradication. Among the 42 patients in the control group, there were 14 eradication failures with 33.33% resistance to clarithromycin. Among the 39 patients in the experimental group, two eradication failures with 5.13% resistance to levofloxacin were observed. The χ(2) value was 6.96. Treatment with levofloxacin was more effective than conventional triple therapy. Triple therapy with levofloxacin can be implemented in populations where resistance to clarithromycin has been observed. Copyright © 2013 Arab Journal of Gastroenterology. Published by Elsevier Ltd.

Live demonstration of endoscopy is one of the most attractive and useful methods for education and is often organized locally in hospitals. However, problems have been apparent in terms of cost, preparation, and potential risks to patients. Our aim was to evaluate a new approach to live endoscopy whereby remote hospitals are connected by the Internet for live endoscopic demonstrations. Live endoscopy was transmitted to the Congress of the Japan Gastroenterological Endoscopic Society by 13 domestic and international hospitals. Patients with upper and lower gastrointestinal diseases and with pancreatobiliary disorders were the subjects of a live demonstration. Questionnaires were distributed to the audience and were sent to the demonstrators. Questions concerned the quality of transmitted images and sound, cost, preparations, programs, preference of style, and adverse events. Of the audience, 91.2% (249/273) answered favorably regarding the transmitted image quality and 93.8% (259/276) regarding the sound quality. All demonstrators answered favorably regarding image quality and 93% (13/14) regarding sound quality. Preparations were completed without any outsourcing at 11 sites (79%) and were evaluated as 'very easy' or 'easy' at all but one site (92.3%). Preparation cost was judged as 'very cheap' or 'cheap' at 12 sites (86%). Live endoscopy connecting multiple international centers was satisfactory in image and sound quality for both audience and demonstrators, with easy and inexpensive preparation. The remote transmission of live endoscopy from demonstrators' own hospitals was preferred to the conventional style of locally organized live endoscopy. © 2015 The Authors Digestive Endoscopy © 2015 Japan Gastroenterological Endoscopy Society.

Achalasia is rare in children. Surgical options include open, laparoscopic and robotic approaches. However, Heller's myotomy remains the treatment of choice. This report describes our experience with robot-assisted Heller's myotomy in children and presents a review of the literature. Included in this study are children who underwent robot-assisted Heller's myotomy for esophageal achalasia via the Da Vinci surgical system between 2004 and 2015 at King Saud University Medical City, Riyadh, Saudi Arabia. The medical records of these patients were reviewed for demographic data, presenting symptoms, diagnostic modalities, operative procedures, complications, outcomes and follow-ups. Six patients were identified. The age of the patients at surgery ranged between 2 and 12 years (mean 7.1 years). The most common presenting symptoms were dysphagia, vomiting and nocturnal cough. Contrast swallow and upper gastrointestinal endoscopy established a diagnosis of esophageal achalasia in all of the patients. Four patients underwent esophageal dilatation 2-5 times before the definitive procedure. All patients underwent successful robot-assisted Heller's myotomy with concomitant partial posterior fundoplication. The postoperative course was uneventful. Five patients had a complete resolution of the symptoms and one patient improved. The follow-up assessments have been consistent and have ranged from 0.5 to 11 years (mean 4.4 years). Robotic-assisted Heller's myotomy for esophageal achalasia in children is safe and effective and is a suitable alternative to open and laparoscopic approaches.

2007-01-01

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

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)

Eosinophilic esophagitis (EoE) prevalence fluctuates according to the population studied and varies from 0.4% in an open population to 6.5% in subjects with esophageal symptoms. Even though this entity has been described in North American and European populations, it is still considered an 'unusual' condition in Latin America. The study aimed to determine EoE prevalence in patients undergoing elective endoscopy in a tertiary referral center in southeastern Mexico. Consecutive patients were evaluated that had been referred to the Medical and Biological Research Institute, Veracruz, Mexico, for upper endoscopy due to gastrointestinal symptoms. Demographic variables and symptoms were analyzed in all the cases. Eight mucosal biopsies of the esophagus (four proximal and four distal) were obtained and were reviewed by a blinded pathologist. Histological diagnosis was established when the mean eosinophil count at a large magnification was ≥15. A total of 235 subjects (137 women, 51.16 years) were evaluated, and EoE prevalence was 1.7% (4/235 95% confidence interval 0.2-3.6%). In all four cases, pH test were normal. Among patients with histological diagnosis of EoE, a greater number of patients with a past history of asthma (50% vs. 19.3%, P = 0.04) and a tendency for a greater frequency of dysphagia (50% vs. 25%, P = 0.10). There were no differences in the endoscopic findings (rings, grooves, plaques, or stricture) when compared with the patients presenting with erosive esophagitis. EoE prevalence among patients undergoing upper endoscopy from southeastern Mexico was 1.7%, which can be regarded as intermediate to low. © 2014 International Society for Diseases of the Esophagus.

Barrett's oesophagus is the primary risk factor for oesophageal adenocarcinoma; erosive oesophagitis is considered an intermediate step with Barrett's oesophagus development potential upon healing. Barrett's oesophagus occurs in 9-19% following erosive oesophagitis but minimal data exists in African Americans. The study aim was to determine if ethnicity is associated with Barrett's oesophagus formation following erosive oesophagitis. Retrospective review of endoscopies from September 2007 to December 2012 was performed. Inclusion criteria were erosive oesophagitis on index endoscopy, repeat endoscopy ≥6 weeks later and non-Hispanic white or African American ethnicity. Barrett's oesophagus frequency following erosive oesophagitis by ethnicity was compared. A total of 14,303 patients underwent endoscopy during the study period; 1636 had erosive oesophagitis. Repeat endoscopy was performed on 125 non-Hispanic white or African American patients ≥6 weeks from the index procedure. Barrett's oesophagus occurred in 8% of non-Hispanic whites while no African American developed it on repeat endoscopy following erosive oesophagitis (p=0.029). No significant difference was seen between ethnic groups in any clinical parameter assessed. African American ethnicity appears to result in decreased Barrett's oesophagus formation following erosive oesophagitis. Further investigation to demonstrate factors resulting in decreased Barrett's oesophagus formation among African Americans should be performed. Copyright © 2015. Published by Elsevier Ltd.

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.

AIM: To present evidence and formulate recommendations for sedation in pediatric gastrointestinal (GI) endoscopy by non-anesthesiologists. METHODS: The databases MEDLINE, Cochrane and EMBASE were searched for the following keywords “endoscopy, GI”, “endoscopy, digestive system” AND “sedation”, “conscious sedation”, “moderate sedation”, “deep sedation” and “hypnotics and sedatives” for publications in English restricted to the pediatric age. We searched additional information published between January 2011 and January 2014. Searches for (upper) GI endoscopy sedation in pediatrics and sedation guidelines by non-anesthesiologists for the adult population were performed. RESULTS: From the available studies three sedation protocols are highlighted. Propofol, which seems to offer the best balance between efficacy and safety is rarely used by non-anesthesiologists mainly because of legal restrictions. Ketamine and a combination of a benzodiazepine and an opioid are more frequently used. Data regarding other sedatives, anesthetics and adjuvant medications used for pediatric GI endoscopy are also presented. CONCLUSION: General anesthesia by a multidisciplinary team led by an anesthesiologist is preferred. The creation of sedation teams led by non-anesthesiologists and a careful selection of anesthetic drugs may offer an alternative, but should be in line with national legislation and institutional regulations.

Capsule endoscopy is a noninvasive method for examining the small intestine. Recently, this method has been used to visualize the colon. However, the capsule often tumbles in the wider colon lumen, resulting in potentially missed pathology. In addition, the capsule does not have the ability to distend collapsed segments of the organ. Self-stabilizing capsule endoscopy is a new method of visualizing the colon without tumbling and with the ability to passively distend colon walls. To quantitatively compare the detection rate of intraluminal suture marker lesions for colonoscopy by using a custom-modified, self-stabilizing capsule endoscope (SCE); an unmodified capsule endoscope (CE) of the same brand; and a standard colonoscope. Four mongrel dogs underwent laparotomy and the implantation of 5 to 8 suture markers to approximate colon lesions. Each dog had both capsule endoscopy and self-stabilizing capsule endoscopy, administered consecutively in random order. In each case, the capsule was inserted endoscopically into the proximal lumen of the colon followed by pharmacologically induced colon peristalsis to propel it distally through the colon. Blinded standard colonoscopy was performed by an experienced gastroenterologist after the capsule endoscopies. Experimental study in a live canine model. Four dogs. Laparotomy, capsule endoscopy, colonoscopy. Comparison of the marker detection rate of the SCE to that of the unmodified MiroCam CE and a colonoscope. The average percentages of the marker detection rate for unmodified capsule endoscopy, self-stabilizing capsule endoscopy, and colonoscopy, respectively, were 31.1%, 86%, and 100% (P < .01), with both self-stabilizing capsule endoscopy and colonoscopy performing significantly better than the unmodified capsule endoscopy. Acute canine model, suture markings poorly representative of epithelial polyps, limited number of animals. The proposed self-stabilizing capsule endoscope delivered a significant improvement in detection rates of colon suture markings when compared with the unmodified capsule endoscope.

[Guide for the use of jet-ventilation during ENT and oral surgery].

2010-10-01

The aim of this synthesis was to give recommendations on the use of jet-ventilation during ENT surgical and endoscopy procedures. Literature was collected from PUBMED and analysed by the members of French association of anaesthesiologists in ENT surgery, all skilled in this field. Presentation of these recommendations was given during the general assembly held in Reims, the 15th May 2009. Jet-ventilation is especially indicated during upper airway endoscopy and laryngeal invasive endoscopic surgery. Furthermore, transtracheal jet ventilation is included on most of difficult oxygenation and difficult intubation algorithm. The main risk of jet-ventilation is pulmonary barotrauma when expiration of injected gas is impeded by an upper airway obstruction. Failure and complications of tracheal puncture are rare when performed by experimented operators. Clinical use of jet ventilation requires a dedicated device. Practice of jet ventilation without intubation may be dangerous when applied without control of driving pressure and end expiratory tracheal pressure. Every anaesthetist should be familiar with transtracheal ventilation since they may face a "cannot ventilate cannot intubate" situation. Upper airway endoscopy and laryngeal surgery are the ideal field for training jet ventilation, even more so as this technique offers perfect operative conditions. To apply this project, jet ventilation should be used more frequently in routine practice. To maintain skill, regular use of these techniques is required. Copyright © 2010 Elsevier Masson SAS.

2017-10-31

Endoscopy services are central to the diagnosis and management of many gastrointestinal (GI) diseases. To evaluate the adequacy of endoscopy services in the public sector hospitals of KwaZulu-Natal (KZN) Province, South Africa, in 2016. A cross-sectional study was performed using a questionnaire completed by the clinical heads of endoscopy units in the public hospitals in KZN. The heads of 11 of the 12 endoscopy units responded. Two units were in tertiary-level hospitals and nine in regional hospitals. A total of 22 353 endoscopic procedures were performed annually, averaging 2 032 cases per annum per centre; they were performed by 89 endoscopists, of whom 72 (80.1%) were general surgeons. There were 0.06 registered gastroenterologists (GEs) per 100 000 population. Each endoscopist performed an average of 263 endoscopies per annum. There were 1.18 endoscopy rooms available per unit, and two units had on-site fluoroscopy available. The average waiting period for an upper endoscopy was 27 (range 7 - 60) days, for colonoscopy 29 (range 7 - 90) days and for duodenoscopy/endoscopic retrograde cholangiopancreatography 13 (range 4 - 20) days. This included patients with alarm symptoms for GI cancers. Equipment breakages interrupted most services, except for one hospital that had a service contract. Unit heads cited lack of equipment, trained staff and maintenance contracts as major shortcomings. Endoscopy units in KZN are not adequately equipped to deal with the endoscopy workload and services are plagued by frequent disruptions, which impact negatively on service delivery. There is a need to train more GEs. Patient care is compromised in these public hospitals.

Upper gastrointestinal bleeding - state of the art.

PubMed

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.

The objective was to determine the results of the treatment of severe and/or refractory epistaxis requiring hospital admission. In addition, the results of arterial ligation versus embolization were compared. Sixty-three patients with severe and/or refractory epistaxis requiring hospital admission between August 2014 and December 2016 were included prospectively. Eleven patients (17%) underwent embolization, 5 (8%) endoscopy ligation and the remaining 47 (75%) underwent conservative treatment with tamponade. The mean age of the patients in which conservative measures were sufficient was 72 years, while the age of those treated with embolization was 71 years and of those who underwent surgery was 53 years. For the patients who underwent conservative treatment or surgery, the average stay was 6 days, compared to 9 days for those who underwent embolization. One patient suffered a hemispheric stroke after embolization. No post-surgical complications were observed. Most cases of severe and/or refractory epistaxis are resolved by conventional tamponade. Endoscopy ligation is associated with a decrease in hospital stay, without serious complications. It is advisable to have all the possible therapeutic options available, for which the presence of interventional radiologists and experienced surgeons is essential to avoid complications and decide the treatment to be performed individually for each patient.

To investigate the clinical effects of endoscopy-assisted sialolithectomy for the calculus in the Stensen's duct. From August 2005 to July 2013, 67 consecutive patients with calculus (or foreign bodies) in the Stensen's duct underwent explorative and interventional endoscopy in our hospital. The stones (or foreign bodies) were removed by endoscopy-assisted technique. After operation, the patients were followed-up periodically, and treatment effects were analyzed. Among the 67 patients, the stones (or foreign bodies) were completely removed in 58 cases, and almost completely removed in 3 cases, with a success rate of 87% (58/67). Among the 61 stone-removed cases, treatment options included direct removal with aid of basket or forceps (24 cases), basket entrapment and opening-up of the ostium (21 cases), basket entrapment and mucosal incision near the ostium (8 cases), open removal via buccal incision (2 cases) and open removal via pre-auricular flap (6 cases). During the 6-90 months' follow-up of the 61 cases, 48 cases were asymptomatic, 7 had mild symptoms, 3 developed ductal obturation, 1 had numbness in the parotid region, and the remaining 2 were missed. Endoscopy-assisted sialolithectomy is a safe and effective gland-preservation technique for the patients with parotid gland calculus.

This study aimed to compare the diagnostic effectiveness of narrow band imaging and autofluorescence imaging for malignant laryngopharyngeal tumours. Between May 2010 and October 2010, 50 consecutive patients with suspected laryngopharyngeal tumour underwent endoscopic laryngopharynx examination. The morphological characteristics of laryngopharyngeal lesions were analysed using high performance endoscopic systems equipped with narrow band imaging and autofluorescence imaging modes. The diagnostic effectiveness of white light image, narrow band imaging and autofluorescence imaging endoscopy for benign and malignant laryngopharyngeal lesions was evaluated. Under narrow band imaging endoscopy, the superficial microvessels of squamous cell carcinomas appeared as dark brown spots or twisted cords. Under autofluorescence imaging endoscopy, malignant lesions appeared as bright purple. The sensitivity of malignant lesion diagnosis was not significantly different between narrow band imaging and autofluorescence imaging modes, but was better than for white light image endoscopy (χ2 = 12.676, p = 0.002). The diagnostic specificity was significantly better in narrow band imaging mode than in both autofluorescence imaging and white light imaging mode (χ2 = 8.333, p = 0.016). Narrow band imaging endoscopy is the best option for the diagnosis and differential diagnosis of laryngopharyngeal tumours.

The patient was consented and taken to theatre for laparoscopic apendicectomy. At operation, the appendix was found to be normal but with surrounding turbid fluid in the right paracolic gutter and subhepatic space. On further inspection, a perforated pre pyloric ulcer was discovered. This was managed laparoscopically with a peritoneal lavage and falciform ligament patch repair. The patient made a good recovery and was discharged 2 days later. At 6 week follow-up the patient had an upper gastrointestinal (GI) endoscopy which showed complete healing of the ulcer. At 6 week follow-up the patient had an upper GI endoscopy which showed complete healing of the ulcer.

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.

Acute upper gastrointestinal bleeding is a rare, but serious complication of gastric bypass surgery. The inaccessibility of the excluded stomach restrains postoperative examination and treatment of the gastric remnant and duodenum, and represents a major challenge, especially in the emergency setting. A 59-year-old patient with previous history of peptic ulcer disease had an upper gastrointestinal bleeding from a duodenal ulcer two years after having a gastric bypass procedure for morbid obesity. After negative upper endoscopy finding, he was urgently evaluated for gastrointestinal bleeding. At emergency laparotomy, the bleeding duodenal ulcer was identified by intraoperative endoscopy through gastrotomy. The patient recovered well after surgical hemostasis, excision of the duodenal ulcer and completion of the remnant gastrectomy. Every general practitioner, gastroenterologist and general surgeon should be aware of growing incidence of bariatric operations and coherently possible complications after such procedures, which modify patient’s anatomy and physiology.

In general and digestive surgical departments, an accurate diagnosis and appropriate treatment of our patients require a wide and continuous access to endoscopy. As many surgical clinics have already developed their own endoscopy units, we plead for the future presence of at least 1 or 2 surgeons, board certified in endoscopy, in every surgical department. We have retrospectively analyzed the activity of the endoscopic unit as a part of the Surgical Clinic of "œDr. I. Cantacuzino" Clinical Hospital since 2007, when it was settled, and its benefits, regarding a higher accessibility for our patients and a reliable support for all the doctors. The number of procedures has increased constantly, from 137, performed by 2 surgeons in 2007 to 1546, in 2015, when 7 surgeons were able to get involved in endoscopic procedures, on a 24/7 schedule. The etiological diagnosis of gastrointestinal hemorrhages, the early detection of gastric, colonic and upper rectal tumors, the follow-up of oncologic patients are only a few of the fields in which endoscopy proved its benefits. Furthermore, surgeons have the practical training and the legal board certification for the approach and treatment of complications. An increased number of surgeons who have also board certification in endoscopy cannot be but very useful. The best way to accomplish this goal would be the inclusion of a digestive endoscopy module during the training program of all future general surgeons. Celsius.

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.

Per-oral endoscopic myotomy (POEM) is safe and efficacious for the management of achalasia cardia (AC). POEM is usually performed under general anesthesia in an endoscopy suite or operating theatre. The current study was conducted with the aim to analyse anesthetic management of patients with AC who underwent POEM at our institution. We retrospectively analysed the data of patients with AC who underwent POEM at our institution from January 2013 to September 2016. All cases were performed in an endoscopy suite under supervision of an anesthesia management team. Pre-procedure endoscopic evacuation of esophagogastric contents was done in all cases. Management strategies used for gas-related adverse events and outcomes were assessed. Four hundred and eighty patients (median age 40 years, range 4-77 years) underwent POEM during the study period. The sub-types of AC were type I (163), type II (297), and type III (20). POEM was successfully completed in 97.5% patients. Gas-related events were noted in 30.6% cases including-capno-thorax in 1%, capno-peritoneum in 12.3%, retroperitoneal air in 16.5%, capno-mediastinum in 0.2%, and capno-pericardium in 0.4% patients. Significant rise in end tidal CO2 (> 45) and peak airway pressure were observed in 8.1% and 5.4% cases, respectively. Drainage was required in 12.3% patients. There was no occurrence of aspiration during or after POEM. POEM could be safely performed in an endoscopy suite under supervision of an expert anesthesia management team. Gas-related adverse events were common during POEM and could be managed with a standardized approach.

The non-operative management of perforated peptic ulcer has previously been shown to be both safe and effective although it remains controversial. A protocol for non-operative management was set up in this hospital in 1989. Adherence to the guidelines in the protocol has been audited over a 6-year period with a review of outcome. The case-notes of patients with a diagnosis of perforated peptic ulcer were reviewed. Twelve guidelines from the protocol were selected for evaluation of compliance to the protocol. Forty-nine patients underwent non-operative treatment initially. Eight patients failed to respond and underwent operation. Complications included abscess formation (seven patients), renal failure (one), gastric ileus (one), chest infection (two), and cardiac failure and stroke (one). Four deaths occurred in this group. Adherence to certain protocol guidelines was poor, notably those concerning prevention of thromboembolism, use of antibiotics, use of contrast examination to confirm the diagnosis and referral for follow-up endoscopy. Two gastric cancers were detected on subsequent endoscopy. This experience demonstrates that non-operative treatment can be used successfully in a general hospital. Adherence to protocol guidelines was found to be variable and the protocol has therefore been simplified. This study highlights the need for an accurate diagnosis and the importance of follow-up endoscopy.

Informed consent (IC) is an essential communication between patient/representative and physician that acknowledges patient autonomy; assent is the equivalent process performed between youth and physician. For clinical procedures involving youth, only the IC process between guardian/parent and physician is required to be performed. Nevertheless, experts recommend that youth undergo assent whenever possible. In the present study, we explored both parental and youth understanding of required IC elements in IC discussions before pediatric endoscopy. Following signing of IC documents on the day of endoscopy at a tertiary care academic medical center, youth and their parents underwent structured interviews to assess comprehension of key elements of the IC process. A total of 88 children and adolescents and their parents were evaluated. Two youth and 12 parents demonstrated comprehensive understanding of key IC elements for pediatric endoscopy. Suboptimal youth understanding was demonstrated for nature of the procedure (25% with adequate understanding) and related risks (17%), and alternatives (14%) to the procedure. Suboptimal parental understanding was demonstrated for procedure alternatives (24%). Youth overall understanding of IC varied by age, whereas parental global understanding of IC varied by physician. Understanding of IC performed for pediatric endoscopy could be improved in both parents and youth. Our findings suggest that interventions targeting parents, youth, and physicians may be helpful. Further study is needed to determine whether our findings are representative of IC understanding at other pediatric endoscopy centers.

Patient experiences with endoscopy visits within a large central Canadian health region were evaluated to determine the relationship between the visit experience and the patients' willingness to return for future endoscopy, and to identify the factors associated with patients' willingness to return. A self-report survey was distributed to 1200 consecutive individuals undergoing an upper and⁄or lower gastrointestinal endoscopy at any one of the six hospital-based endoscopy facilities in the region. The Spearman correlation coefficient was used to assess the association between the patients' overall rating of the visits and willingness to return for repeat procedures under similar medical circumstances. Logistic regression analyses were performed to identify the factors associated with willingness to return for repeat endoscopy and overall satisfaction (rating) of the visit. A total of 529 (44%) individuals returned the questionnaire, with 45% rating the visit as excellent and 56% indicating they were extremely likely to return for repeat endoscopy. There was a low moderate correlation between overall rating of the visit and patients' willingness to return for repeat endoscopy (r=0.30). The factors independently associated with patient willingness to return for repeat endoscopy included perceived technical skills of the endoscopists (OR 2.7 [95% CI 1.3 to 5.5]), absence of pain during the procedure (OR 2.2 [95% CI 1.3 to 3.6]) and history of previous endoscopy (OR 2.4 [95% CI 1.4 to 4.1]). In contrast, the independent factors associated with the overall rating of the visit included information provided pre- and postprocedure, wait time before and on the day of the visit, and the physical environment. To facilitate patient return for needed endoscopy, it is important to assess patients' willingness to return because positive behavioural intent is not simply a function of satisfaction with the visit.

Sedation with detomidine and acepromazine influences the endoscopic evaluation of laryngeal function in horses.

Endoscopy of the upper airways of horses is used as a diagnostic tool and at purchase examinations. On some occasions it is necessary to use sedation during the procedure and it is often speculated that the result of the examination might be influenced due to the muscle-relaxing properties of the most commonly used sedatives. To evaluate the effect of detomidine (0.01 mg/kg bwt) and acepromazine (0.05 mg/kg bwt) on the appearance of symmetry of rima glottidis, ability to abduct maximally the arytenoid cartilages and the effect on recurrent laryngeal neuropathy (RLN) grade. Forty-two apparently normal horses underwent endoscopic examination of the upper airways on 3 different occasions, under the influence of 3 different treatments: no sedation (control), sedation with detomidine and sedation with acepromazine. All examinations were performed with a minimum of one week apart. The study was performed as an observer-blind cross-over study. Sedation with detomidine had a significant effect on the RLN grading (OR = 2.91) and ability maximally to abduct the left arytenoid cartilages (OR = 2.91). Sedation with acepromazine resulted in OR = 2.43 for the RLN grading and OR = 2.22 for the ability to abduct maximally. The ability to abduct maximally the right arytenoid cartilage was not altered. Sedating apparently healthy horses with detomidine or acepromazine significantly impairs these horses' ability to abduct fully the left but not the right arytenoid cartilage. This resulted in different diagnosis with respect to RLN when comparing sedation to no sedation. Since the ability to abduct the right arytenoid cartilage fully is not altered by sedation, it is speculated that horses changing from normal to abnormal laryngeal function when sedated, might be horses in an early stage of the disease. To confirm or reject these speculations, further studies are needed. Until then sedation during endoscopy should be used with care.

Peptic ulcer bleeding can be fatal. Non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids and immunosuppressive agents are administered for long-term usage. The present study assessed the association between peptic ulcer bleeding and administration of NSAIDs, corticosteroids and immunosuppressive agents. Furthermore, the efficacy of lowering the risk of peptic ulcer bleeding with proton pump inhibitors (PPI) and histamine 2 receptor antagonists (H2RA) was evaluated. Medical records were retrospectively analyzed for patients subjected to an upper gastrointestinal (GI) endoscopy performed at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) from October 2014 to September 2015. During this period, a total of 1,023 patients underwent an upper GI endoscopy. A total of 1,023 patients, including 431 males (age, 68.1±12.9 years) and 592 females (age, 66.4±12.3 years), who had been administered NSAIDs, corticosteroids, immunosuppressive agents, PPIs and H2RAs, were respectively enrolled. Endoscopic findings of the patients were reviewed and their data were statistically analyzed. Logistic regression analysis was used to determine the odds ratio of peptic ulcer bleeding for each medication; immunosuppressive agents had an odds ratio of 5.83, which was larger than that for NSAIDs (4.77). The Wald test was applied to confirm the correlation between immunosuppressive agents and peptic ulcer bleeding. Furthermore, χ 2 tests were applied to the correlation between peptic ulcer bleeding and administration of PPIs or H2RAs. Immunosuppressive agents had the largest χ 2 , and the P-value was 0.03. Administration of PPIs was significantly correlated with non-peptic ulcer bleeding (P=0.02); furthermore, a tendency toward non-peptic ulcer bleeding with administration of H2RA was indicated, but it was not statistically significant (P=0.12). In conclusion, immunosuppressive agents were correlated with peptic ulcer bleeding and PPIs were effective at lowering the risk of peptic ulcer bleeding.

The aim of this study was to externally validate the four commonly used scoring systems in the risk stratification of patients with upper gastrointestinal bleed (UGIB). Patients of UGIB who underwent endoscopy within 24 h of presentation were stratified prospectively using the pre-endoscopy Rockall score (PRS) >0, complete Rockall score (CRS) >2, Glasgow Blatchford bleeding scores (GBS) >3, and modified GBS (m-GBS) >3 scores. Patients were followed up to 30 days. Prognostic accuracy of the scores was done by comparing areas under curve (AUC) in terms of overall risk stratification, re-bleeding, mortality, need for intervention, and length of hospitalization. One hundred and seventy-five patients were studied. All four scores performed better in the overall risk stratification on AUC [PRS = 0.566 (CI: 0.481-0.651; p-0.043)/CRS = 0.712 (CI: 0.634-0.790); p<0.001)/GBS = 0.810 (CI: 0.744-0.877; p->0.001); m-GBS = 0.802 (CI: 0.734-0.871; p<0.001)], whereas only CRS achieved significance in identifying re-bleed [AUC-0.679 (CI: 0.579-0.780; p = 0.003)]. All the scoring systems except PRS were found to be significantly better in detecting 30-day mortality with a high AUC (CRS = 0.798; p-0.042)/GBS = 0.833; p-0.023); m-GBS = 0.816; p-0.031). All four scores demonstrated significant accuracy in the risk stratification of non-variceal patients; however, only GBS and m-GBS were significant in variceal etiology. Higher cutoff scores achieved better sensitivity/specificity [RS > 0 (50/60.8), CRS > 1 (87.5/50.6), GBS > 7 (88.5/63.3), m-GBS > 7(82.3/72.6)] in the risk stratification. GBS and m-GBS appear to be more valid in risk stratification of UGIB patients in this region. Higher cutoff values achieved better predictive accuracy.

Helicobacter pylori, one of the most prevalent human pathogens, is associated with chronic gastritis, peptic ulcer disease, and possibly gastric cancer and primary gastric lymphoma. The need to treat these patients has necessitated the development of improved methods to diagnose H. pylori infection. We present the preliminary assessment of a 13C-urea breath test (UBT) in which the expired 13CO2 is detected in a rapid, simple, inexpensive way by the LARA (Laser Assisted Ratio Analyzer) System (Alimenterics, Inc., Morris Plains, NJ). Eighty-seven consecutive patients, examined for upper gastrointestinal symptoms, underwent endoscopy. H. pylori infection was established by antral biopsies and a rapid urease test (CLOtest). The UBT was performed between 2 and 24 hours after endoscopy. Of the 84 analyzable patients, 70 were found to be H. pylori-positive either by histology or by CLOtest. All 70 were positive by the LARA UBT, yielding a sensitivity of 100%. Fourteen patients were negative for H. pylori by histology and the CLOtest. Of these, 12 were negative by the LARA UBT and 2 were positive, yielding a specificity of 85.7%; because of the limitations of H. pylori detection by histology or urease assays, however, the specificity of the UBT may have been underestimated. Our study demonstrates the feasibility of a nonradioactive, rapid UBT based on the LARA system and suggests the need for its more detailed evaluation.

The aim of this study was to assess the value of drug-induced sleep endoscopy (DISE) using a custom-made simulation bite in maximal comfortable protrusion (MCP) of the mandible, in the prediction of treatment outcome for obstructive sleep apnea (OSA) with a mandibular advancement device (MAD). Two hundred patients (74% male; age 46 ± 9 years; apnea-hypopnea index [AHI] 19 ± 13 h(-1) sleep; body mass index [BMI] 27 ± 4 kg m(-2) ) with sleep-disordered breathing underwent DISE with a simulation bite in MCP. One hundred and thirty-five patients with an established diagnosis of OSA commenced MAD treatment. The associations between the findings during DISE with simulation bite and treatment outcome were evaluated. Treatment response was defined as a reduction in AHI following MAD treatment of ≥ 50% compared to baseline. Overall MAD treatment response in the studied population was 69%. The results of this study demonstrated a statistically significant association between a positive effect of the simulation bite on the upper airway patency during DISE and treatment response with MAD (P < 0.01). The results of this study suggest that the use of a simulation bite in maximal comfortable protrusion (MCP) of the mandible, as used during DISE in patients with OSA, tends to be effective in predicting treatment response of MAD treatment. © 2012 European Sleep Research Society.

The aim of this study was to identify possible upper airway obstructions causing a higher continuous positive airway pressure (CPAP) titration level, utilizing drug-induced sleep endoscopy (DISE). A total of 76 patients with obstructive sleep apnea (OSA) underwent CPAP titration and DISE. DISE findings were recorded using the VOTE classification system. Polysomnographic (PSG) data, anthropometric variables, and patterns of airway collapse during DISE were analyzed with CPAP titration levels. A significant association was found between the CPAP titration level and BMI, oxygen desaturation index (ODI), apnea-hypopnea index (AHI), and neck circumference (NC) (P < 0.001, P < 0.001, P < 0.001, and P < 0.001, respectively, by Spearman correlation). Patients with concentric collapse of the velum or lateral oropharyngeal collapse were associated with a significantly higher CPAP titration level (P < 0.001 and P = 0.043, respectively, by nonparametric Mann-Whitney U test; P < 0.001 and P = 0.004, respectively, by Spearman correlation). No significant association was found between the CPAP titration level and any other collapse at the tongue base or epiglottis. By analyzing PSG data, anthropometric variables, and DISE results with CPAP titration levels, we can better understand possible mechanisms resulting in a higher CPAP titration level. We believe that the role of DISE can be expanded as a tool to identify the possible anatomical structures that may be corrected by oral appliance therapy or surgical intervention to improve CPAP compliance.

None of current diagnostic methods has been proven to be a reliable tool for gastro-esophageal reflux disease (GERD). Pepsin in saliva has been proposed as a promising diagnostic biomarker for gastro-esophageal reflux. We aimed to determine the diagnostic value of salivary pepsin detection for GERD. Two hundred and fifty patients with symptoms suggestive of GERD and 35 asymptomatic healthy volunteers provided saliva on morning waking, after lunch and dinner for pepsin determination using the Peptest lateral flow device. All patients underwent 24-h multichannel intraluminal impedance pH (24-h MII-pH) monitoring and upper gastrointestinal endoscopy. Based on 24-h MII-pH and endoscopy study, patients were defined as GERD (abnormal MII-pH results and/or reflux esophagitis) and non-GERD otherwise. Patients with GERD had a higher prevalence of pepsin in saliva and higher pepsin concentration than patients with non-GERD and healthy controls (P < 0.001 for all). The pepsin test had a sensitivity of 73% and a specificity of 88.3% for diagnosing GERD using the optimal cut-off value of 76 ng/mL. Postprandial saliva samples collected when the symptoms occurred had a more powerful ability to identify GERD. Salivary pepsin test had moderate diagnostic value for GERD. It may be a promising tool to replace the use of currently invasive tools with advantages of non-invasive, easy to perform and cost effective.

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.

Small intestinal tumors are rare with adenocarcinoma of the small intestine accounting for less than 2% of all gastrointestinal cancers. Primary jejunal adenocarcinoma constitutes a minute portion of small intestine adenocarcinomas. Clinically, this cancer presents at latter stages of its progression, mainly due to vague and non-specific symptoms, and the difficulty encountered in accessing the jejunum on upper endoscopy. Diagnosis of jejunal adenocarcinoma is usually inconclusive with the use of computed tomography (CT) scan, small bowel series, or upper endoscopy. Laparoscopy followed by frozen section biopsy provides a definitive diagnosis. In the past decade, balloon-assisted enteroscopy (BAE) and capsule endoscopy have become popular as useful modalities for diagnosing small bowel diseases. Wide excisional jejunectomy is the only treatment option with an estimated 5-year survival of 40-65%. Physicians are advised to suspect jejunal adenocarcinoma as a differential diagnosis in patients who present with non-specific symptoms of abdominal pain, nausea, vomiting, weight loss, anemia, gastrointestinal bleeding or signs of small bowel obstruction. We present a rare case of a 37-year-old woman with suspected bilateral ovarian masses, which was immunohistochemically confirmed as primary jejunal adenocarcinoma with bilateral ovarian metastasis.

Zenker’s diverticulum: flexible versus rigid repair

PubMed Central

Beard, Kristen

2017-01-01

Zenker’s diverticula (ZDs) are a relatively common cause of cervical dysphagia. Diagnosis is best by a good upper GI exam though upper endoscopy should be performed as well. Treatment is either by open, transcervical approaches or trans-oral. Over the past 20 years, transoral approach has mostly replace transcervical approaches due to less pain, no scarring and a rapid recovery. Transoral approaches are either using rigid access or flexible endoscopy. Today, the most common approach is transoral stapling using a 12 mm laparoscopic linear cutting stapler. This has the drawbacks of requiring extreme neck extension, the massive size of the stapler making visualization mostly impossible and the current staple design that does not cut/staple all the way to the end of the blades—resulting in a residual pouch. Flexible endoscopy allows a more tailored approach under direct vision, the myotomy can even be extended beyond the diverticulum and onto the esophageal wall to minimize the risk of incomplete myotomy. Experienced endoscopists report high technical success and low complication. Success rates are similar but maybe slightly higher than with ridged transoral approaches or open surgery. Today, flexible endoscopic Zenkers is our preferred initial approach—with open or ridged being reserved for special indications. PMID:28446979

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.

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.

Esophageal cancer (ECA) is an important cancer in Malaysia. The aim of the study is to review the demographic data and clinical presentation of patients with ECA seen at the University of Malaya Medical Centre, Kuala Lumpur. Patients with histologically proven ECA were recruited for the study. Patients' case notes, endoscopy and operating theater records were reviewed. All cases were histologically confirmed. A total of 143 patients with ECA was diagnosed between 1998 and 2003. The mean age of the patients was 63.1 +/- 12.1 years with a male : female ratio of 1.8:1. Of these 50.3 percent were Indians, 32.9 percent, Chinese and 16.8 percent Malays. The overall hospital-based prevalence rates per 100 000 admissions according to races were: Malay; 23.5, Chinese; 57.4 and Indian; 134.1. The location of the tumors was: upper; 16 (11.2%) middle; 52 (36.4%) and lower; 75 (52.4%). The histological type of ECA were: squamous cell carcinomas; 113 (79.0%) and adenocarcinomas; 30 (21.0%). The ECA stage at diagnosis, was: II; 18 (12.6%), III; 23 (16.1%) and IV; 102 (71.3%). Only 24 (16.8%) patients underwent surgery and13 (9.1%) were considered curative. Overall 114 (79.7%) patients underwent palliative endoscopic stenting and six (4.2%) were given other palliative therapy including radiotherapy. Squamous cell cancer was the predominant type. ECA presents late in our patients and only a minority of patients underwent curative surgery.

This study aimed to compare the body composition, dietary intake and serum levels of vitamins and minerals, and exocrine pancreatic function in patients late after pancreaticoduodenectomy (PD) and healthy subjects. Fifteen patients (PD group) who had undergone PD over 1 year before the study and 15 health volunteers (control group) were included in the study. All volunteers underwent dietary intake evaluation, body composition, laboratory data, exocrine pancreatic function by elastase-1, and carbon (C )-labeled triglycerides in breath tests. The PD group subjects also underwent upper gastrointestinal endoscopy and small intestinal bacterial overgrowth analysis. Nutrient intake was adequate, and there were no differences in body mass index and mineral serum levels between the groups. The PD group showed lower serum levels of retinol, α-tocopherol, and ascorbic acid. Small intestinal bacterial overgrowth occurred in 39% of the patients. Fecal elastase-1 was lower in the PD group. The PD group had a higher C peak time; the cumulative label C recovery in 7 hours was similar in both groups. Fecal elastase-1 decreased, and the excretion of C in breath was similar to healthy controls. Although the data point toward an adaptation in the absorptive capacity of fats, A, C, and E hypovitaminosis indicate that some absorptive insufficiency persists late after PD.

Data on the clinical presentation of constitutional mismatch repair deficiency syndrome (CMMRD) is accumulating. However, as the extraintestinal manifestations are often fatal and occur at early age, data on the systematic evaluation of the gastrointestinal tract is scarce. Here we describe 11 subjects with verified biallelic carriage and who underwent colonoscopy, upper endoscopy and small bowel evaluation. Five subjects were symptomatic and in six subjects the findings were screen detected. Two subjects had colorectal cancer and few adenomatous polyps (19, 20 years), three subjects had polyposis-like phenotype (13, 14, 16 years), four subjects had few adenomatous polyps (8, 12-14 years) and two subjects had no polyps (both at age 6). Of the three subjects in the polyposis-like group, two subjects had already developed high-grade dysplasia or cancer and one subject had atypical juvenile polyps suggesting juvenile polyposis. Three out of the five subjects that underwent repeated exams had significant findings during short interval. The gastrointestinal manifestations of CMMRD are highly dependent upon age of examination and highly variable. The polyps may also resemble juvenile polyposis. Intensive surveillance according to current guidelines is mandatory. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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.

Refractory gastro-oesophageal reflux disease: diagnosis and management.

PubMed

Liu, Julia J; Saltzman, John R

2009-10-01

Refractory gastro-oesophageal reflux disease (GORD) is described when reflux symptoms have not responded to 4-8 weeks of proton pump inhibitor therapy and occurs in a heterogeneous mixture of patients. The causes of refractory GORD include inadequate acid suppression, non-acid gastro-oesophageal reflux, and non-reflux causes of GORD symptoms including achalasia, gastroparesis and functional heartburn. Upper gastrointestinal tract endoscopy should initially be performed to identify the presence of oesophagitis, and exclude other diagnoses including eosinophilic oesophagitis and peptic ulcer disease. Patients with refractory symptoms but with a normal upper endoscopy are more difficult to diagnose and may require ambulatory pH monitoring, impedance testing, oesophageal motility tests and gastric emptying scans. The primary goal of treatment is symptom reduction and eventual elimination, which can be achieved with proper identification of the underlying cause of the symptoms.

A human Echinostoma hortense infection was diagnosed by gastroduodenoscopy. An 81-year-old Korean male, living in Yeongcheon-shi, Gyeongsangbuk-do and with epigastric discomfort of several days duration, was subjected to upper gastrointestinal endoscopy. He was in the habit of eating fresh water fish. Two live worms were found in the duodenal bulb area and were removed using an endoscopic forcep. Based on their morphological characteristics, the worms were identified as E. hortense. The patient was treated with praziquantel 10 mg/kg as a single dose. The source of the infection in this case remains unclear, but the fresh water fish consumed, including the loach, may have been the source. This is the second case of E. hortense infection diagnosed by endoscopy in Korea. PMID:12815324

Acute upper and lower gastrointestinal bleeding, enteral feeding, cecostomy tubes and luminal strictures are some of the common reasons for gastroenterology service. While surgery was initially considered the main treatment modality, the advent of both therapeutic endoscopy and interventional radiology have resulted in the paradigm shift in the management of these conditions. In this paper, we discuss the patient’s work up, indications, and complementary roles of endoscopic and angiographic management in the settings of gastrointestinal bleeding, enteral feeding, cecostomy tube placement and luminal strictures. These conditions often require multidisciplinary approaches involving a team of interventional radiologists, gastroenterologists and surgeons. Further, the authors also aim to describe how the fields of interventional radiology and gastrointestinal endoscopy are overlapping and complementary in the management of these complex conditions.

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.

To analyze the related factors of complications and treatment efficacy with flexible endoscopy for esophageal foreign body (FB). In a retrospective study with consecutive data, 101 adults including 52 males and 49 females with esophageal FB impaction between January 2005 and December 2012 admitted into Department of Gastroenterology's Endoscopic Unit at Peking University Third Hospital were included, aged (49 ± 21) years. (1) FB impaction in upper and middle esophagus accounted for 87.1% (n = 88) of all esophageal FBs. No significant difference existed in interval time from impaction to removal of FB impacted between upper, middle and lower esophagus (P > 0.05) . (2) Patients with esophageal FB seeking hospital treatment accounted for 82.2% (n = 83) within 24 h and 99.0% (n = 100) within 48 h. Food lump, fish bone, chicken bone and fruit seeds accounted for 76.2% (n = 77). (3) Positive rates were 91.3% (21/23) and 24.1% (7/29) with upper gastrointestinal barium contrast and chest or abdominal plain film. The success rate was 94.1% (n = 95) with flexible endoscopy for removal of FB. (4) Denture was the most difficult FB for removal. Four patients in all 11 patients with denture impacted were not removed successfully with flexible endoscopy. (5) The complication (except for mild scratch) rate was 48.5% (n = 49) and the perforation rate 3.0% (n = 3) . Whether complications took place or not was independent of age, location of impaction, time from impaction to removal and size of FB (all P > 0.05) , but dependent on piercing into esophageal wall, concomitant with esophageal stricture and types of FB (all P < 0.01) . Whether perforation or not was independent of any above factor. Esophageal FB should be removed as soon as possible within 24 h especially for those with sharp edges and piercing into esophageal wall.

The etiology of gastric cancer is multifactorial. Marked differences in the incidence of gastric cancer among different ethnic groups living in the same geographical area have been observed. This study looked at ethnic and dietary factors in patients with gastric cancer diagnosed at a tertiary referral centre in Sikkim over a period of one year. Patients of 60 years and above were included in the study and divided into four ethnic groups : Bhutias, Lepchas, Rais and other groups. 211 cases underwent upper GI endoscopy and 32 were diagnosed to have gastric cancer. Gastric cancer incidence was highest in Bhutia ethnic group. A trend towards higher intake of smoked meats, fermented vegetables, salt tea, and H.pylori positivity in the Bhutia ethnic group was associated with higher incidence of gastric cancer as compared to other ethnic groups. The study with a referral centre bias showed that Bhutia ethnic group had a higher incidence of gastric cancer as compared to other ethnic groups.

A 77-year-old man underwent total gastrectomy with D1+ lymph node dissection after being diagnosed with cT4aN2M0, cStage ⅢB gastric cancer. Peritoneal dissemination was detected in the bursa omentalis. The pathological diagnosis after surgery was pT4aN3b (21/41) M1 (P1). He was treated with 6 courses of S-1 chemotherapy. Two years after surgery, upper gastrointestinal endoscopy revealed the presence of a tumor in the mid-thoracic esophagus. It was diagnosed to as metastatic esophageal cancer and treated with combination chemotherapy consisting of docetaxel (25 mg/m2, days 1, 8, 15) and cisplatin (25 mg/m2, days 1, 8, 15) in a 28-day cycle. A clinically complete response was observed after 5 courses of chemotherapy. Currently, the patient is alive with no signs of recurrence 12 months after the initial recurrence.

AIM: To investigate whether autofluorescence imaging (AFI) endoscopy can distinguish non-erosive reflux disease (NERD) from functional heartburn (FH). METHODS: In this prospective observational trial, 127 patients presenting with typical reflux symptoms for > 6 mo were screened. All the participants underwent endoscopy, during which white light imaging (WLI) was followed by AFI. Finally 84 patients with normal esophageal appearance on WLI were enrolled. It was defined as being suggestive of NERD if one or more longitudinal purple lines longer than one centimeter were visualized in the distal part of the esophagus during AFI endoscopy. Ambulatory 24-h multichannel intraluminal impedance and pH monitoring was also performed. After standard proton-pump inhibitor (PPI) tests, subjects were divided into an NERD group and an FH group and the diagnostic performance of AFI endoscopy to differentiate NERD from FH was evaluated. RESULTS: Of 84 endoscopy-negative patients, 36 (42.9%) had a normal pH/impedance test. Of these, 26 patients with favorable responses to PPI tests were classified as having NERD. Finally 10 patients were diagnosed with FH and the others with NERD. Altogether, 68 (81.0%) of the 84 patients were positive on AFI endoscopy. In the NERD group, there were 67 (90.5%) patients with abnormal esophageal findings on AFI endoscopy while only 1 (10%) patient was positive on AFI endoscopy in the FH group. The sensitivity and specificity of AFI in differentiating NERD from FH were 90.5% (95%CI: 81.5%-96.1%) and 90.0% (95%CI: 55.5%-99.7%), respectively. Meanwhile, the accuracy, positive predictive value and negative predictive value of AFI in differentiating between NERD and FH were 90.5% (95%CI: 84.2%-96.8%), 98.5% (95%CI: 92.1%-99.9%) and 56.3% (95%CI: 30.0%-80.2%), respectively. CONCLUSION: Autofluorescence imaging may serve as a complementary method in evaluating patients with NERD and FH. PMID:27076770

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'.

The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute upper gastrointestinal bleeding (UGIB) with special reference to peptic ulcer bleeding (PUB). The study included 2198 consecutive patients referred to our emergency department due to acute UGIB from January 2008 to December 2012. All patients underwent urgent upper GI endoscopy within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed-up. The cumulative incidence of UGIB was 126/100,000 in the 5-year period. Two out of five patients had a bleeding peptic ulcer; in total, 440 (52.3%) had bleeding gastric ulcer, 356 (42.3%) had bleeding duodenal ulcer, 17 (2%) had both bleeding gastric and duodenal ulcers, and 29 (3.5%) patients had bleeding ulcers on gastroenteric anastomoses. PUB was more common in men. The mean patient age was 65.9 years. The majority of patients (57%) with PUB were taking agents that attenuate the cytoprotective function of gastric and duodenal mucosa. Rebleeding occurred in 77 (9.7%) patients and 47 (5.9%) patients required surgical intervention. The 30-day morality was 5.2% and 10% of patients died from uncontrolled bleeding and concomitant diseases. In conclusion, PUB is the main cause of UGIB, characterized by a significant rebleeding rate and mortality.

We studied the features of upper gastrointestinal bleeding (UGIB) in patients taking antithrombotic drugs. The records of 430 patients taking antithrombotic drugs who underwent emergency endoscopy for UGIB in Saga Medical School Hospital between 2002 and 2011 were studied. We also compared the characteristics of our cohort of 11,919 patients prescribed antithrombotic drugs in our hospital between 2002 and 2011. UBGI patients of variceal bleeding were not included in this study. 186 patients presented with UGIB in the first period (2002-2006) and 244 in the second period (2007-2011). The proportion of patients infected with Helicobacter pylori was lower in the second period, while the proportion taking antithrombotic drugs rose significantly. Peptic ulcer disease was responsible for the majority of bleeding episodes; however, bleeding from other sources is increasing. In the whole cohort, the risk of UGIB was 1.08%; however, of the 31.8% who also took an acid-secretion inhibitor only 18 (0.28%) developed bleeding. In contrast, 102 (1.87%) of those not taking an acid-secretion inhibitor developed UGIB, a statistically significant difference. Risk of UGIB in Japanese patients taking antithrombotics was 1.01% and the incidence is increasing. Acid-secretion inhibitors reduced the risk of antithrombotic drug-related UGIB.

Baveno VI Recommendation on Avoidance of Screening Endoscopy in Cirrhotic Patients: Are We There Yet?

Introduction Recent studies assessed the predictive value of liver transient elastography, combined or not with platelet count, for the presence of esophageal varices in patients with liver cirrhosis, and multiple cutoffs have been proposed. The Baveno VI consensus states that patients with compensated advanced chronic liver disease, liver stiffness <20 kPa, and a platelet count >150,000 have a very low risk of having varices requiring treatment and can avoid screening endoscopy. We aimed to validate this recommendation in a cohort of cirrhotic patients. Methods Retrospective analysis of all patients evaluated at the Gastroenterology Department (Centro Hospitalar de Lisboa Central) between September 2009 and October 2015 with a liver stiffness (FibroScan®) compatible with liver cirrhosis as well as upper endoscopy and blood tests within 12 months from elastography. Patients on propranolol ≥80 mg/day or carvedilol ≥12.5 mg/day, as well as those with previous variceal bleeding, variceal endoscopic treatments, or cirrhosis decompensations were excluded. We validated the new Baveno VI recommendation and explored alternative cutoffs. Results Ninety-seven patients were analyzed, 76.3% (74/97) male, mean age 54.3 ± 11.2 years. Most patients (55.7%) had no varices and 14.4% had varices requiring treatment. Most patients (78.4%) had cirrhosis related to chronic hepatitis C. If the new Baveno VI recommendation had been applied to this cohort, upper endoscopy would have been avoided in 11.3% (11/97) of patients, none of them with esophageal varices requiring treatment: specificity 100%, sensitivity 13.3%, positive predictive value 100%, and negative predictive value 16.3% for absence of varices requiring treatment. If screening endoscopy had been avoided in those patients with liver stiffness <30 kPa and platelet count ≥120,000, endoscopy would have been avoided in 27.8% (27/97) of patients, none of whom with esophageal varices requiring treatment: specificity 100%, sensitivity 32.5%, positive predictive value 100%, and negative predictive value 20% for absence of varices requiring treatment. Conclusions The new Baveno VI criteria identified compensated cirrhotic patients without varices requiring treatment in whom screening endoscopy could have been avoided safely. Further studies are needed to confirm these findings and potentially explore more ambitious but still safe cutoffs for those criteria. PMID:28848787

A portable disposable ultrathin endoscope (DUE) with high visual quality and maneuverability would reduce the need for expensive facilities and emergency endoscopy could be available anywhere. It would increase patient satisfaction, prevent unnecessary sedation, and reduce infection. Our aim was to evaluate the usefulness of portable DUE in performing percutaneous endoscopic gastrostomy (PEG). We prospectively enrolled patients who underwent PEG under DUE guidance and compared them with historical controls who underwent PEG under conventional ultrathin endoscopy (CUE) guidance. The primary outcomes were successful stomach visualization and PEG tube insertion. Twenty-five patients (19 male) were enrolled and compared with 25 gender and indication-matched controls. The most common indications for PEG were aspiration due to stroke or brain injury, dementia, and head and neck cancer. Entrance into the stomach was achieved in 92.0% (23/25) and 96% (24/25) in the DUE and CUE groups, and PEG was performed in 91.3% (21/23) and 95.8% (23/24), respectively. The mean insertion time for the DUE and CUE groups were 22.7 ± 9.3 minutes and 17.1 ± 5.7 minutes (P = 0.044). The 3 cases of failure to reach the stomach in both groups were caused by esophageal blockage. The 3 cases of failed PEG tube insertion were caused by poor visualization of the insertion site. Bleeding and pneumoperitoneum occurred in 1 and 2 patients in the DUE group. One case of fever was noted in the CUE group. All adverse events were conservatively managed. Our study shows that portable DUE in facilities without endoscopy equipment may be clinically feasible.

Abstract Background: A portable disposable ultrathin endoscope (DUE) with high visual quality and maneuverability would reduce the need for expensive facilities and emergency endoscopy could be available anywhere. It would increase patient satisfaction, prevent unnecessary sedation, and reduce infection. Our aim was to evaluate the usefulness of portable DUE in performing percutaneous endoscopic gastrostomy (PEG). Methods: We prospectively enrolled patients who underwent PEG under DUE guidance and compared them with historical controls who underwent PEG under conventional ultrathin endoscopy (CUE) guidance. The primary outcomes were successful stomach visualization and PEG tube insertion. Results: Twenty-five patients (19 male) were enrolled and compared with 25 gender and indication-matched controls. The most common indications for PEG were aspiration due to stroke or brain injury, dementia, and head and neck cancer. Entrance into the stomach was achieved in 92.0% (23/25) and 96% (24/25) in the DUE and CUE groups, and PEG was performed in 91.3% (21/23) and 95.8% (23/24), respectively. The mean insertion time for the DUE and CUE groups were 22.7 ± 9.3 minutes and 17.1 ± 5.7 minutes (P = 0.044). The 3 cases of failure to reach the stomach in both groups were caused by esophageal blockage. The 3 cases of failed PEG tube insertion were caused by poor visualization of the insertion site. Bleeding and pneumoperitoneum occurred in 1 and 2 patients in the DUE group. One case of fever was noted in the CUE group. All adverse events were conservatively managed. Conclusions: Our study shows that portable DUE in facilities without endoscopy equipment may be clinically feasible. PMID:27902596

The newly developed technique of peroral endoscopic myotomy (POEM) has been shown to be effective in several short- and mid-term studies. Limited information is available about the adequacy of immediate post-POEM monitoring tests. POEM was performed under general anesthesia in 228 patients (59.6% male, mean age 45.6 ± 15.5 years). Post-procedural checks comprised clinical and laboratory examination, and, during post-procedure days 1-5, endoscopy and-in the first 114 cases-radiologic examination using water-soluble contrast (1st group); the remaining patients underwent post-procedure controls without radiology (2nd group). Main outcome was value of endoscopic compared to radiologic control for recognition of early adverse events. In the first group, routine fluoroscopic contrast swallow suggested minor leakages at the mucosal entry site in two cases which was confirmed endoscopically in only one. Endoscopy revealed two minor entry site leakages and, in six additional cases, dislocated clips without leakage (overall 5.3%). All eight patients underwent reclipping and healed without clinical sequelae. In the 2nd group, endoscopy showed 5 clip dislocations (all reclipped) and one ischemic cardiac perforation in a patient with clinical deterioration on post-POEM day 1 who had to undergo surgery after confirmation of leakage by CT. Radiologic monitoring (contrast swallow) after POEM is not useful and can be omitted. Even routine endoscopic monitoring for detection and closure of minor defects of the mucosal entry site yields limited information with regards to final outcome; major complications are very rare and probably associated with clinical deterioration.

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.

Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and⁄or anatomical anomalies. To determine the motor and anatomical causes of dysphagia. A total of 41 adults, followed at the Esophageal Atresia Clinic at Hôpital Saint-Luc (Montreal, Quebec), were approached to particpate in the present prospective study. Evaluation was completed using upper endoscopy, manometry and barium swallow for the participants who consented. The medical charts of respondents were systematically reviewed from the neonatal period to 18 years of age to assess medical and surgical history. All 41 patients followed at the clinic consented and were included in the study. Dysphagia was present in 73% of patients. Esophagogastroduodenoscopy was performed in 32 patients: hiatal hernia was present in 62% (n=20); esophageal diverticulum in 13% (n=4); macroscopic Barrett esophagus in 31% (n=10); and esophagitis in 19% (n=6). Histological esophagitis was present in 20% and intestinal metaplasia in 10%. There were no cases of dysplagia or adenocarcinoma. Esophageal manometry was performed on 56% of the patients (n=23). Manometry revealed hypomotility in 100% of patients and included an insufficient number of peristaltic waves in 96%, nonpropagating peristalsis in 78% and low-wave amplitude in 95%. Complete aperistalsis was present in 78%. The lower esophageal sphincter was abnormal in 12 (52%) patients, with incomplete relaxation the most common anomaly. Of the 41 patients, 29 (71%) consented to a barium swallow, which was abnormal in 13 (45%). The anomalies found were short esophageal dilation in 28%, delay in esophageal emptying in 14%, diverticula in 14% and stenosis in 7% of patients. There was more than one anomaly in 14% of patients. Dysphagia was a highly prevalent symptom in adults who underwent surgery for esophageal atresia. The present study is the first to demonstrate that motor and anatomical abnormalities may be implicated in causes of dysphagia in this population. Furthermore, these anomalies may be demonstrated with simple investigations such as endoscopy, manometry and barium swallow.

A 58-year-old man with hepatitis B cirrhosis noticed black stools and underwent an endoscopy at a community hospital. The presence of esophageal varices (EVs) was confirmed, but the bleeding point was not found. He was referred to our institution and underwent a second endoscopy. Extensive white patches of esophageal candidiasis were visible on endoscopy by white-light imaging (WLI), but it was difficult to find the fibrin cap of the EVs. This was easier under narrow-band imaging (NBI), however, as the color turned red from absorption by hemoglobin adhered to it. We retrospectively measured the color differences (CD) between the fibrin cap and the surrounding mucosa 10 times using the CIE (L*a*b*) color space method. The median value of CD increased after NBI (13.9 → 43.0, p < 0.001), with increased visibility. However, the median CD between the white patch and surrounding mucosa decreased after NBI (44.8 → 30.3, p < 0.001). The fibrin cap was paler than the white patch of candidiasis, but the increased visibility of the fibrin cap by NBI enabled it to be found more easily. This is the first report of a case in which NBI was helpful in locating a fibrin cap of EVs.

Both jejunal nodular lymphoid hyperplasia (NLH) and polyethylene glycol (PEG)-3350 hypersensitivity are extremely rare. We describe a 30-year-old female who had previously taken a PEG-3350 bowel preparation without adverse effects, and presented for evaluation of chronic diarrhea. An upper and lower gastrointestinal endoscopy, and small bowel series were scheduled. PEG-3350 and electrolytes for oral solution was prescribed for bowel cleansing. During consumption of the bowel preparation she developed urticarial hypersensitivity. An alternative bowel preparation was used. Colonoscopy and upper endoscopy were normal, but small bowel series revealed innumerable sand-like lucencies in the jejunum. NLH was confirmed on biopsy from antegrade enteroscopy. This is the first case report on the pathological jejunal NLH in association with the PEG-3350 urticarial hypersensitivity. The potential pathophysiological etiology of this association is discussed.

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.

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.

Compare nasal endoscopy with 3 mm versus conventional 4 mm rigid 30° endoscopes for visualization, patient comfort, and examiner ease. Ten adults with no previous sinus surgery underwent bilateral nasal endoscopy with both 4 mm and 3 mm endoscopes (resulting in 20 paired nasal endoscopies). Visualization, patient discomfort and examiner's difficulty were assessed with every endoscopy. Sino-nasal structures were checked on a list if visualized satisfactorily. Patients rated discomfort on a standardized numerical pain scale (0-10). Examiners rated difficulty of examination on a scale of 1-5 (1 = easiest). Visualization with 3 mm endoscope was superior for the sphenoid ostium ( P  = 0.002), superior turbinate ( P  = 0.007), spheno-ethmoid recess ( P  = 0.006), uncinate process ( P  = 0.002), cribriform area ( P  = 0.007), and Valve of Hasner ( P  = 0.002). Patient discomfort was not significantly different for 3 mm vs. 4 mm endoscopes but correlated with the examiners' assessment of difficulty ( r  = 0.73). The examiner rated endoscopy with 4 mm endoscopes more difficult ( P  = 0.027). The 3 mm endoscope was superior in visualizing the sphenoid ostium, superior turbinate, spheno-ethmoid recess, uncinate process, cribriform plate, and valve of Hasner. It therefore may be useful in assessment of spheno-ethmoid recess, nasolacrimal duct, and cribriform area pathologies. Overall, patients tolerated nasal endoscopy well. Though patient discomfort was not significantly different between the endoscopes, most discomfort with 3 mm endoscopes was noted while examining structures difficult to visualize with the 4 mm endoscope. Patients' discomfort correlated with the examiner's assessment of difficulty.

AIM: To evaluate the safety of endoscopic procedures in neutropenic and/or thrombocytopenic cancer patients. METHODS: We performed a literature search for English language studies in which patients with neutropenia and/or thrombocytopenia underwent endoscopy. Studies were included if endoscopic procedures were used as part of the evaluation of neutropenic and/or thrombocytopenic patients, yielding 13 studies. Two studies in which endoscopy was not a primary evaluation tool were excluded. Eleven relevant studies were identified by two independent reviewers on PubMed, Scopus, and Ovid databases. RESULTS: Most of the studies had high diagnostic yield with relatively low complication rates. Therapeutic endoscopic interventions were performed in more than half the studies, including high-risk procedures, such as sclerotherapy. Platelet transfusion was given if counts were less than 50000/mm3 in four studies and less than 10000/mm3 in one study. Other thrombocytopenic precautions included withholding of biopsy if platelet count was less than 30000/mm3 in one study and less than 20000/mm3 in another study. Two of the ten studies which examined thrombocytopenic patient populations reported bleeding complications related to endoscopy, none of which caused major morbidity or mortality. All febrile neutropenic patients received prophylactic broad-spectrum antibiotics in the studies reviewed. Regarding afebrile neutropenic patients, prophylactic antibiotics were given if absolute neutrophil count was less than 1000/mm3 in one study, if the patient was undergoing colonoscopy and had a high inflammatory condition without clear definition of significance in another study, and if the patient was in an aplastic phase in a third study. Endoscopy was also withheld in one study for severe pancytopenia. CONCLUSION: Endoscopy can be safely performed in patients with thrombocytopenia/neutropenia. Prophylactic platelet transfusion and/or antibiotic administration prior to endoscopy may be considered in some cases and should be individualized. PMID:26674926

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.

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.

This study investigated the role of drug-induced sleep endoscopy (DISE) in the surgical treatment planning of patients with obstructive sleep apnea syndrome (OSAS). This study was conducted using patients diagnosed with OSAS between January 2007 and March 2009, who were scheduled for surgical treatment. DISE was performed using propofol in patients considered to have upper respiratory tract obstruction as indicated by Muller's maneuver. After completing the sleep endoscopy, the patient was intubated and surgery was performed (tonsillectomy and uvulopalatopharyngoplasty). A successful operation was defined as a decrease in the respiratory disturbance index to below 5 or a decrease of ≥50 % following the operation. The study included 20 patients (4 female and 16 male) aged 19-57 years. No statistically significant correlation between modified Mallampati class and operation success or between the polysomnographic stage of disease and operation success was identified. A significantly high operation success rate was found in the group with obstruction of the upper airway according to DISE (p < 0.05), whereas a significantly low operation success rate was found in the group with obstruction of the lower airway according to DISE (p < 0.01). DISE may be used to identify the localization of obstruction for diagnostic purposes, and it can be helpful in selecting the treatment method.

Esophagogastric junction (EGJ) distensibility and distension-mediated peristalsis can be assessed with the functional lumen imaging probe (FLIP) during a sedated upper endoscopy. We aimed to describe esophageal motility assessment using FLIP topography in patients presenting with dysphagia. In all, 145 patients (aged 18-85 years, 54% female) with dysphagia that completed upper endoscopy with a 16-cm FLIP assembly and high-resolution manometry (HRM) were included. HRM was analyzed according to the Chicago Classification of esophageal motility disorders; major esophageal motility disorders were considered "abnormal". FLIP studies were analyzed using a customized program to calculate the EGJ-distensibility index (DI) and generate FLIP topography plots to identify esophageal contractility patterns. FLIP topography was considered "abnormal" if EGJ-DI was <2.8 mm 2 /mm Hg or contractility pattern demonstrated absent contractility or repetitive, retrograde contractions. HRM was abnormal in 111 (77%) patients: 70 achalasia (19 type I, 39 type II, and 12 type III), 38 EGJ outflow obstruction, and three jackhammer esophagus. FLIP topography was abnormal in 106 (95%) of these patients, including all 70 achalasia patients. HRM was "normal" in 34 (23%) patients: five ineffective esophageal motility and 29 normal motility. In all, 17 (50%) had abnormal FLIP topography including 13 (37%) with abnormal EGJ-DI. FLIP topography provides a well-tolerated method for esophageal motility assessment (especially to identify achalasia) at the time of upper endoscopy. FLIP topography findings that are discordant with HRM may indicate otherwise undetected abnormalities of esophageal function, thus FLIP provides an alternative and complementary method to HRM for evaluation of non-obstructive dysphagia.

Previous reports suggest that sex differences may exist in dreaming under anesthesia, but their results were inconclusive. The current study explored sex differences in the incidence and content of dreams during short propofol sedation for upper gastrointestinal endoscopy and investigated whether sex differences or dream content affect patient satisfaction with sedation. A total of 200 patients (100 men and 100 women) undergoing upper gastrointestinal endoscopy participated in this study. Patients were interviewed with the modified Brice questionnaire about the incidence and the content of dreams, and satisfaction with sedation was assessed. The results showed that the incidence of dreaming was significantly higher in men (31%) than in women (17%) (P=0.02), but recovery time was similar. In men, 45% (14/31) of dreamers reported positive emotional content and only 6% (2/31) reported negative emotional content. In contrast, in women, 18% (3/17) reported positive and 29% (5/17) reported negative content (P=0.04). Men reported dreams that were more vivid, meaningful, familiar, and memorable (P<0.01). No significant sex differences were observed in the emotional intensity of dreams, and emotional content did not influence patients' satisfaction. In sum, sex differences existed in dreaming during short propofol sedation despite similar recovery time and matching in terms of age. Men reported dreaming more frequently and had a higher incidence of recall for their dream narratives. In particular, men reported significantly more positive emotional content, less negative emotional content, and more meaningful content. Dreamer satisfaction with sedation was not influenced by sex or dream content.

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.

To investigate changes in upper airway volume parameters measured by computerized tomography scans in patients with surgically treated by anterior palatoplasty of whom having pure snoring and mild-moderate obstructive sleep apnea. A prospective study on consecutively anterior palatoplasty performed pure snoring and obstructive sleep apnea patients. Computerized tomography scans were obtained preoperatively and following anterior palatoplasty procedure to measure changes in upper airway volume. Patients underwent diagnostic drug induced sleep endoscopy to assess the site of obstruction. Preoperative and postoperative measurements were compared using student's t test and Chi-square test. Twenty-two patients (16 men and 6 women, age 48.22 ± 9.23, body mass index 25.85 ± 2.57) completed the trial. Anterior palatoplasty was associated with an increase in total upper airway volume from 4.81 ± 1.73 cm 3 before treatment to 6.57 ± 2.03 cm 3 after treatment (p < 0.005). Change in soft palate thickness did not vary significantly (p < 0.039). The mean soft palate length has changed from 4.13 ± 0.41 to 3.93 ± 0.51 cm (p < 0.001). The preoperative and postoperative measurements of cross-sectional areas and volumes all showed significant difference except velopharynx minimal lateral airway dimension. The operational procedure increased the total upper airway volume much more in men than in women (p < 0.05). Results of this study indicate that anterior palatoplasty operation appears to produce significant increase in upper airway volume and cross sectional area. It does not seem to have an effect on lateral airway dimension. Computerized tomography is a quick and noninvasive imaging technique that allows for quantitative assessment of the velopharyngeal patency changes.

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.

We have proposed a new user interface with workflow customization, implemented and evaluted in Endoscopy Department Mini-PACS that has been introduced and routinely used for two years at Toshiba General Hospital. We have set some task at endoscopy image acquisition units during examinations for two different types of user interfaces and compared performance. One is a command-button based operation using a remote control, and another is that with eight graphic buttons which are displayed on a CRT monitor and can be customized. Results of the two-year study show that mean number of input diagnosis codes per examination with graphic and customized interface is significantly greater than that with conventional interface. Also, mean time to complete one upper gastric endoscopy examination with new user interface is about 17 percent less than that with conventional interface. These result suggest that systems with the visualized and customized operation and feedback encourages physicians to use more functions and to compete tasks more efficiently than systems with conventional command-button based user interfaces.

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.

Videoscopic Heller Myotomy with Intraoperative Endoscopy Promotes Optimal Outcomes

PubMed Central

Bloomston, Mark; Brady, Patrick

2002-01-01

Background and Objectives: Minimally invasive surgical techniques are applicable to achalasia, but the optimum approach to intraoperative assessment of adequacy of myotomy remains unestablished. We set out to show that videoscopic Heller myotomy with concurrent endoscopy ensures adequacy of myotomy while limiting postoperative clinically apparent reflux. Methods: Seventy-eight consecutive patients with achalasia underwent videoscopic Heller myotomy with concomitant endoscopy between 1992 and 1998. Fundoplication was not routinely undertaken. Results: Preoperative symptoms consisted of dysphagia (100%), emesis/regurgitation (68%), heartburn (58%), and postprandial chest pain (49%). Following myotomy, significant improvement (P < 0.0001) was seen in dysphagia (43%), postprandial chest pain (13%), and emesis/regurgitation (9%) at a mean follow-up of 33 ± 2.2 months. Mean reflux score (scale 0 to 5) improved from 3.7 ± 0.3 to 1.5 ± 0.2 (P < 0.0001). Improvement in symptoms was reported in 96% of patients. Fundoplication was used in 8 patients as part of hiatus reconstruction (n = 6) or repair of esophageal perforation (n = 2). Conclusions: Intraoperative endoscopy during video-scopic Heller myotomy guides the extent and adequacy of myotomy. By utilizing a focused dissection with preservation of the natural antireflux mechanisms around the gastroesophageal junction and limiting the extent of myotomy along the cardia, postoperative reflux symptoms are minimized. We advocate concomitant endoscopy during Heller myotomy to guide myotomy and submit that routine fundoplication is clinically unnecessary. PMID:12113416

Capsule endoscopy was approved by the FDA in 2001. Gastrointestinal bleeding and inflammatory bowel disease are the main indications. It has been available in our hospital since 2004. We retrospectively analysed data from patients who underwent small bowel capsule endoscopy in our hospital from October 2004 to April 2015. Indications were divided into: Obscure gastrointestinal bleeding (occult and overt), inflammatory bowel disease, and other indications. Findings were divided into: Vascular lesions, inflammatory lesions, other lesions, normal studies, and inconclusive studies. A total of 1027 out of 1291 small bowel studies were included. Mean patient age was 56.45 years; 471 were men and 556 women. The most common lesion observed was angiectasia, as an isolated finding or associated with other lesions. Findings were significant in up to 80% of studies when the indication was gastrointestinal bleeding, but in only 50% of studies in inflammatory bowel disease. Diagnostic yield was low in the group «other indications». No major complications were reported. Small bowel capsule endoscopy has high diagnostic yield in patients with gastrointestinal bleeding, but yield is lower in patients with inflammatory bowel disease. Our experience shows that capsule endoscopy is a safe and useful tool for the diagnosis of small bowel disease. The diagnostic yield of the technique in inflammatory bowel disease must be improved.

Evaluation of dysphagia typically starts with esophagogastroduodenoscopy (EGD); further testing is pursued if this is negative. When no mucosal, structural, or motor esophageal disorders are identified with persisting symptoms, functional dysphagia is considered. We evaluated outcomes in patients undergoing EGD for dysphagia, and estimated prevalence of functional dysphagia. The endoscopy database at single tertiary care center was interrogated to identify EGDs performed for an indication of 'dysphagia' over a 12-month period (2008-09). Electronic medical records were reviewed over the next 8 years to assess if an etiology was identified. Data were analyzed to assess the diagnostic yield of endoscopy and subsequent tests in the evaluation of dysphagia. Of 5486 EGDs, 822 (15.0%) were performed for dysphagia in 694 patients (58.4 ± 0.6 year, range: 18-95 year, 55.8% female). Of these, 529 (76.2%) had EGD findings that explained dysphagia; another 22 (3.2%) had findings on histopathology. Of the remainder 143 patients (20.6%) with normal index EGD, 38 (26.6%) patients underwent barium esophagram with 15 (39.5%) having abnormal studies. 19 patients (13.3%) underwent esophageal high resolution manometry with 12 (63.2%) being abnormal, and 7 had a mechanism for dysphagia on alternate testing. A repeat EGD was abnormal in 6 patients, while 45 patients were lost to follow-up. 42 patients had complete resolution of symptoms despite normal endoscopy, of which 30 were treated empirically with a proton pump inhibitor (PPI). Only 16 patients had no findings on evaluation, and had continued dysphagia symptoms, representing true functional dysphagia in 2.3% of all dysphagia patients and 11.2% of patients with normal EGD. Endoscopy remains the test with the highest yield (over 75%) for a diagnosis in patients presenting with dysphagia; secondary tests are useful when endoscopy does not provide a diagnosis. Benign strictures and GERD-related etiologies are leading causes; PPI therapy is useful even when testing is negative. Functional dysphagia is extremely rare, accounting for <2.5% of all dysphagia.

Hereditary hemorrhagic telangiectasia (HHT) is a rare genetic disease that results in mucocutaneous telangiectasias and arteriovenous visceral malformations. Nasal telangiectasias lead to recurrent epistaxis, which affects up to 96% of patients. Different morphologic classifications and methods of visualization of nasal lesions have been described in the literature. We developed a new method of intraoperative endoscopy based on the intravenous administration of fluorescein. Preliminary data of this technique are reported. After the intravenous administration of sodium fluorescein, an intraoperative fluorescein-guided endoscopy was carried out using photographic customized yellow filters on top of a 0-degree, 4-mm endoscope. In 2015, 65 HHT patients underwent surgery for their epistaxis in our institution, and in 7 patients (3 males, 4 females; mean age, 54 years) an intraoperative fluorescein-guided intraoperative nasal endoscopy was performed. No adverse events or complications were observed. First impressions regarding the usage of this technique in HHT patients seem to be promising and positive in terms of efficacy and safety. However, further studies with larger cohorts of patients should be performed in order to better investigate the use of this method for diagnostic and surgical purposes in HHT. © 2016 ARS-AAOA, LLC.

Recent studies have shown that pronase can improve mucosal visibility, but this agent is not uniformly available for human use worldwide. This study aimed to assess the efficacy of N-acetylcysteine (NAC), a mucolytic agent, in improving mucus elimination as measured by decreased endoscopic water flushes during narrow-band imaging (NBI) endoscopy. A consecutive series of patients scheduled for upper gastrointestinal endoscopy at outpatient clinics were enrolled in this double-blind, randomized controlled trial. The control group drank a preparation of 100 mg dimethicone (5 ml at 20 mg/ml) plus water up to 100 ml, and the NAC group drank 300 mg NAC plus 100 mg dimethicone and water up to 100 ml. During the endoscopy, the endoscopist used as many flushes of water as deemed necessary to produce a satisfactory NBI view of the entire gastric mucosa. In all, 177 patients with a mean age of 51 years were evaluated in this study. Significantly lesser water was used for flushing during NBI endoscopy for the NAC group than the control group; 40 ml (30-70, 0-120) versus 50 ml (30-100, 0-150) (median (interquartile range, range), p = 0.0095). Considering the safety profile of NAC, decreasing the number of water flushes for optimal vision and unavailability of pronase in some areas, the authors suggest the use of add-on NAC to eliminate mucus during NBI endoscopy.

We aimed to prospectively determine patient burden and patient preference for magnetic resonance enteroclysis, capsule endoscopy and balloon-assisted enteroscopy in patients with suspected or known Crohn's disease (CD) or occult gastrointestinal bleeding (OGIB).  Consecutive consenting patients with CD or OGIB underwent magnetic resonance enteroclysis, capsule endoscopy and balloon-assisted enteroscopy. Capsule endoscopy was only performed if magnetic resonance enteroclysis showed no high-grade small bowel stenosis. Patient preference and burden was evaluated by means of standardized questionnaires at five moments in time. From January 2007 until March 2009, 76 patients were included (M/F 31/45; mean age 46.9 years; range 20.0-78.4 years): 38 patients with OGIB and 38 with suspected or known CD. Seventeen patients did not undergo capsule endoscopy because of high-grade stenosis. Ninety-five percent (344/363) of the questionnaires were suitable for evaluation. Capsule endoscopy was significantly favored over magnetic resonance enteroclysis and balloon-assisted enteroscopy with respect to bowel preparation, swallowing of the capsule (compared to insertion of the tube/scope), burden of the entire examination, duration and accordance with the pre-study information. Capsule endoscopy and magnetic resonance enteroclysis were significantly preferred over balloon-assisted enteroscopy for clarity of explanation of the examination, and magnetic resonance enteroclysis was significantly preferred over balloon-assisted enteroscopy for bowel preparation, painfulness and burden of the entire examination. Balloon-assisted enteroscopy was significantly favored over magnetic resonance enteroclysis for insertion of the scope and procedure duration. Pre- and post-study the order of preference was capsule endoscopy, magnetic resonance enteroclysis and balloon-assisted enteroscopy. Capsule endoscopy was preferred to magnetic resonance enteroclysis and balloon-assisted enteroscopy; it also had the lowest burden. Magnetic resonance enteroclysis was preferred over balloon-assisted enteroscopy for clarity of explanation of the examination, bowel preparation, painfulness and burden of the entire examination, and balloon-assisted enteroscopy over magnetic resonance enteroclysis for scope insertion and study duration. © 2012 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

A primary intestinal lymphangiectasia patient diagnosed by capsule endoscopy and confirmed at surgery: A case report

Intestinal lymphangiectasia (IL) is a rare disease characterized by dilated lymphatic vessles in the intestinal wall and small bowel mesentery which induce loss of protein and lymphocytes into bowel lumen. Because it most often occurs in the intestine and cannot be detected by upper gastroendoscopy or colonoscopy, and the value of common image examinations such as X-ray and computerized tomography (CT) are limited, the diagnosis of IL is difficult, usually needing the help of surgery. Capsule endoscopy is useful in diagnosing intestinal diseases, such as IL. We here report a case of IL in a female patient who was admitted for the complaint of recurrent edema accompanied with diarrhea and abdominal pain over the last twenty years, and aggravated ten days ago. She was diagnosed by M2A capsule endoscopy as a primary IL and confirmed by surgical and pathological examination. PMID:17465517

Obstructive sleep apnea syndrome has multifactorial causes. Although indications for surgery are evaluated by well-known diagnostic tests in the awake state, these do not always correlate with satisfactory surgical results. To undertake a systematic review on endoscopy during sleep, as one element of the diagnosis routine, aiming to identify upper airway obstruction sites in adult patients with OSAS. By means of electronic databases, a systematic review was performed of studies using drug-induced sleep endoscopy to identify obstruction sites in patients with OSAS. Ten articles were selected that demonstrated the importance of identifying multilevel obstruction, especially in relation to retrolingual and laryngeal collapse in OSAS. DISE is an additional method to reveal obstruction sites that have not been detected in awake patients. Copyright © 2015 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Advances in the management of childhood portal hypertension.

McKiernan, Patrick; Abdel-Hady, Mona

2015-05-01

Portal hypertension is one of the most serious complications of childhood liver disease, and variceal bleeding is the most feared complication. Most portal hypertension results from cirrhosis but extra hepatic portal vein obstruction is the single commonest cause. Upper gastrointestinal endoscopy endoscopy remains necessary to diagnose gastro-esophageal varices. Families of children with portal hypertension should be provided with written instructions in case of gastrointestinal bleeding. Children with large varices should be considered for primary prophylaxis on a case-by-case basis. The preferred method is variceal band ligation. Children with acute bleeding should be admitted to hospital and treated with antibiotics and pharmacotherapy before urgent therapeutic endoscopy. All children who have bled should then receive secondary prophylaxis. The preferred method is variceal band ligation and as yet there is little evidence to support the use of β-blockers. Children with extrahepatic portal vein obstruction should be assessed for suitability of mesoportal bypass.

The cost-effectiveness of initial strategies in managing Canadian patients with uninvestigated upper gastrointestinalsymptoms remains controversial. To assess the cost-effectiveness of six management approaches to uninvestigated upper gastrointestinal symptoms in the Canadian setting. The present study analyzed data from four randomized trials assessing homogeneous and complementary populations of Canadian patients with uninvestigated upper gastrointestinal symptoms with comparable outcomes. Symptom-free months, qualityadjusted life-years (QALYs) and direct costs in Canadian dollars of two management approaches based on the Canadian Dyspepsia Working Group (CanDys) Clinical Management Tool, and four additional strategies (two empirical antisecretory agents, and two prompt endoscopy) were examined and compared. Prevalence data, probabilities, utilities and costs were included in a Markov model, while sensitivity analysis used Monte Carlo simulations. Incremental cost-effectiveness ratios and cost-effectiveness acceptability curves were determined. Empirical omeprazole cost $226 per QALY ($49 per symptom-free month) per patient. CanDys omeprazole and endoscopy approaches were more effective than empirical omeprazole, but more costly. Alternatives using H2-receptor antagonists were less effective than those using a proton pump inhibitor. No significant differences were found for most incremental cost-effectiveness ratios. As willingness to pay (WTP) thresholds rose from $226 to $24,000 per QALY, empirical antisecretory approaches were less likely to be the most costeffective choice, with CanDys omeprazole progressively becoming a more likely option. For WTP values ranging from $24,000 to $70,000 per QALY, the most clinically relevant range, CanDys omeprazole was the most cost-effective strategy (32% to 46% of the time), with prompt endoscopy-proton pump inhibitor favoured at higher WTP values. Although no strategy was the indisputable cost effective option, CanDys omeprazole may be the strategy of choiceover a clinically relevant range of WTP assumptions in the initial management of Canadian patients with uninvestigated dyspepsia.

Selecting patients appropriately for upper endoscopy (EGD) is crucial for efficient use of endoscopy. The objective of this study was to compare different clinical strategies and statistical methods to select patients for EGD, namely appropriateness guidelines, age and/or alarm features, and multivariate and artificial neural network (ANN) models. A nationwide, multicenter, prospective study was undertaken in which consecutive patients referred for EGD during a 1-month period were enrolled. Before EGD, the endoscopist assessed referral appropriateness according to the American Society for Gastrointestinal Endoscopy (ASGE) guidelines, also collecting clinical and demographic variables. Outcomes of the study were detection of relevant findings and new diagnosis of malignancy at EGD. The accuracy of the following clinical strategies and predictive rules was compared: (i) ASGE appropriateness guidelines (indicated vs. not indicated), (ii) simplified rule (>or=45 years or alarm features vs. <45 years without alarm features), (iii) logistic regression model, and (iv) ANN models. A total of 8,252 patients were enrolled in 57 centers. Overall, 3,803 (46%) relevant findings and 132 (1.6%) new malignancies were detected. Sensitivity, specificity, and area under the receiver-operating characteristic curve (AUC) of the simplified rule were similar to that of the ASGE guidelines for both relevant findings (82%/26%/0.55 vs. 88%/27%/0.52) and cancer (97%/22%/0.58 vs. 98%/20%/0.58). Both logistic regression and ANN models seemed to be substantially more accurate in predicting new cases of malignancy, with an AUC of 0.82 and 0.87, respectively. A simple predictive rule based on age and alarm features is similarly effective to the more complex ASGE guidelines in selecting patients for EGD. Regression and ANN models may be useful in identifying a relatively small subgroup of patients at higher risk of cancer.

Background Transnasal endoscopy (TNE) is performed with an ultrathin scope via the nasal passages and is increasingly used. This review covers the technical characteristics, tolerability, safety and acceptability of TNE and also diagnostic accuracy, use as a screening tool and therapeutic applications. It includes practical advice from an ear, nose, throat (ENT) specialist to optimise TNE practice, identify ENT pathology and manage complications. Methods A Medline search was performed using the terms “transnasal”, “ultrathin”, “small calibre”, “endoscopy”, “EGD” to identify relevant literature. Results There is increasing evidence that TNE is better tolerated than standard endoscopy as measured using visual analogue scales, and the main area of discomfort is nasal during insertion of the TN endoscope, which seems remediable with adequate topical anaesthesia. The diagnostic yield has been found to be similar for detection of Barrett's oesophagus, gastric cancer and GORD-associated diseases. There are some potential issues regarding the accuracy of TNE in detecting small early gastric malignant lesions, especially those in the proximal stomach. TNE is feasible and safe in a primary care population and is ideal for screening for upper gastrointestinal pathology. It has an advantage as a diagnostic tool in the elderly and those with multiple comorbidities due to fewer adverse effects on the cardiovascular system. It has significant advantages for therapeutic procedures, especially negotiating upper oesophageal strictures and insertion of nasoenteric feeding tubes. Conclusions TNE is well tolerated and a valuable diagnostic tool. Further evidence is required to establish its accuracy for the diagnosis of early and small gastric malignancies. There is an emerging role for TNE in therapeutic endoscopy, which needs further study. PMID:28839865

Capsule endoscopy (CE) has transformed investigation of the small bowel providing a non-invasive, well tolerated means of accurately visualising the distal duodenum, jejunum and ileum. Since the introduction of small bowel CE thirteen years ago a high volume of literature on indications, diagnostic yields and safety profile has been presented. Inclusion in national and international guidelines has placed small bowel capsule endoscopy at the forefront of investigation into suspected diseases of the small bowel. Most commonly, small bowel CE is used in patients with suspected bleeding or to identify evidence of active Crohn’s disease (CD) (in patients with or without a prior history of CD). Typically, CE is undertaken after upper and lower gastrointestinal flexible endoscopy has failed to identify a diagnosis. Small bowel radiology or a patency capsule test should be considered prior to CE in those at high risk of strictures (such as patients known to have CD or presenting with obstructive symptoms) to reduce the risk of capsule retention. CE also has a role in patients with coeliac disease, suspected small bowel tumours and other small bowel disorders. Since the advent of small bowel CE, dedicated oesophageal and colon capsule endoscopes have expanded the fields of application to include the investigation of upper and lower gastrointestinal disorders. Oesophageal CE may be used to diagnose oesophagitis, Barrett’s oesophagus and varices but reliability in identifying gastroduodenal pathology is unknown and it does not have biopsy capability. Colon CE provides an alternative to conventional colonoscopy for symptomatic patients, while a possible role in colorectal cancer screening is a fascinating prospect. Current research is already addressing the possibility of controlling capsule movement and developing capsules which allow tissue sampling and the administration of therapy. PMID:24976712

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.

Purpose: To investigate whether neonatal dacryocystoceles and dacryocystitis are associated with nasolacrimal duct cysts, and to report the outcomes of treatment of these disorders. Methods: This was a retrospective medical record review of two groups of infants with nasolacrimal duct (NLD) obstruction. The first group had dacryocystoceles with or without dacryocystitis. The second group had NLD obstruction with symptoms severe enough to require early NLD probing. All of the patients underwent NLD probing and nasal endoscopy. When present, NLD cysts were removed. Results: In the first group, 33 infants had dacryocystoceles. Acute dacryocystitis was present in 16 patients, 12 had noninfected dacryocystoceles that did not resolve, and 5 had dacryocystoceles that resolved but severe symptoms persisted. All of the patients had NLD cysts that were surgically removed. The symptoms resolved after surgery in 31 patients (94%). In the second group, 27 infants less than 6 months old without dacryocystoceles underwent early NLD probing and endoscopy due to severity of symptoms. Twelve (44%) of these patients had NLD cysts. The symptoms resolved in 11 (92%) of 12 patients following NLD probing and cyst removal. Conclusions: Neonatal dacryocystoceles are almost always associated with NLD cysts. The success rate of NLD probing and endoscopic cyst removal in these patients is excellent. Nasolacrimal duct cysts also are present in many young infants with severe symptoms of NLD obstruction. Nasal endoscopy is an important adjunct to the management of these infants. PMID:23818736

To assess rates of further bleeding, surgery and mortality in patients hospitalized owing to peptic ulcer bleeding. Consecutive patients hospitalized for peptic ulcer bleeding and treated with a proton pump inhibitor (PPI) (esomeprazole or pantoprazole) were identified retrospectively in 12 centers in Spain. Patients were included if they had high-risk stigmata (Forrest class Ia-IIb, underwent therapeutic endoscopy and received intravenous PPI ≥120 mg/day for ≥24 h) or low-risk stigmata (Forrest class IIc-III, underwent no therapeutic endoscopy and received intravenous or oral PPI [any dose]). Of 935 identified patients, 58.3% had high-risk stigmata and 41.7% had low-risk stigmata. After endoscopy, 88.3% of high-risk patients and 22.1% of low-risk patients received intravenous PPI therapy at doses of at least 160 mg/day. Further bleeding within 72 h occurred in 9.4% and 2.1% of high- and low-risk patients, respectively (p < 0.001). Surgery to stop bleeding was required within 30 days in 3.5% and 0.8% of high- and low-risk patients, respectively (p = 0.007). Mortality at 30 days was similar in both groups (3.3% in high-risk and 2.3% in low-risk patients). Among patients hospitalized owing to peptic ulcer bleeding and treated with PPIs, patients with high-risk stigmata have a higher risk of further bleeding and surgery, but not of death, than those with low-risk stigmata.

Improving early detection of gastric cancer: a novel systematic alphanumeric-coded endoscopic approach.

PubMed

Emura, Fabian; Gralnek, Ian; Baron, Todd H

2013-01-01

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.

Oesophageal papilloma and Barrett's oesophagus are benign lesions known as risk factors of carcinoma in the oesophagus. Therefore, it is important to diagnose these early changes before neoplastic transformation. Autofluorescence endoscopy is a fast and non-invasive method of imaging of tissues based on the natural fluorescence of endogenous fluorophores. The aim of this study was to prove the diagnostic utility of autofluorescence endoscopy with digital image processing in histological diagnosis of endoscopic findings in the upper digestive tract, primarily in the imaging of oesophageal papilloma. During the retrospective analysis of about 200 endoscopic procedures in the upper digestive tract, 67 cases of benign, precancerous or cancerous changes were found. White light endoscopy (WLE) image, single-channel (red or green) autofluorescence images, as well as green and red fluorescence intensities in two modal fluorescence image and red-to-green (R/G) ratio (Numerical Colour Value, NCV) were correlated with histopathologic results. The NCV analysis in autofluorescence imaging (AFI) showed increased R/G ratio in cancerous changes in 96% vs. 85% in WLE. Simultaneous analysis with digital image processing allowed us to diagnose suspicious tissue as cancerous in all of cases. Barrett's metaplasia was confirmed in 90% vs. 79% (AFI vs. WLE), and 98% in imaging with digital image processing. In benign lesions, WLE allowed us to exclude tissue as malignant in 85%. Using autofluorescence endoscopy R/G ratio was increased in only 10% of benign changes causing the picture to be interpreted as suspicious, but when both methods were used together, 97.5% were cases excluded as malignancies. Mean R/G ratios were estimated to be 2.5 in cancers, 1.25 in Barrett's metaplasia and 0.75 in benign changes and were statistically significant (p=0.04). Autofluorescence imaging is a sensitive method to diagnose precancerous and cancerous early stages of the diseases located in oesophagus. Especially in two-modal imaging including white light endoscopy, autofluorescence imaging with digital image processing seems to be a useful modality of early diagnostics. Also in observation of papilloma changes, it facilitates differentiation between neoplastic and benign lesions and more accurate estimation of the risk of potential malignancy.

While endoscopy is the most commonly used modality for diagnosing upper GI tract disease, this procedure usually requires patient sedation that increases cost and mandates its operation in specialized settings. In addition, endoscopy only visualizes tissue superfically at the macroscopic scale, which is problematic for many diseases that manifest below the surface at a microscopic scale. Our lab has previously developed technology termed tethered capsule OCT endomicroscopy (TCE) to overcome these diagnostic limitations of endoscopy. The TCE device is a swallowable capsule that contains optomechanical components that circumferentially scan the OCT beam inside the body as the pill traverses the organ via peristalsis. While we have successfully imaged ~100 patients with the TCE device, the optics of our current device have many elements and are complex, comprising a glass ferrule, optical fiber, glass spacer, GRIN lens and prism. As we scale up manufacturing of this device for clinical translation, we must decrease the cost and improve the manufacturability of the capsule's optical configuration. In this abstract, we report on the design and development of simplificed TCE optics that replace the GRIN lens-based configuration with an angle-polished ball lens design. The new optics include a single mode optical fiber, a glass spacer and an angle polished ball lens, that are all fusion spliced together. The ball lens capsule has resolutions that are comparable with those of our previous GRIN lens configuration (30µm (lateral) × 7 µm (axial)). Results in human subjects show that OCT-based TCE using the ball lens not only provides rapid, high quality microstructural images of upper GI tract, but also makes it possible to implement this technology inexpensively and on a larger scale.

A high level of preoperative anxiety is common among patients undergoing medical and surgical procedures. Anxiety impacts of gastroenterological procedures on psychological and physiological responses are worth consideration. To analyze the effect of listening to Vedic chants and Indian classical instrumental music on anxiety levels and on blood pressure (BP), heart rate (HR), and oxygen saturation in patients undergoing upper gastrointestinal (GI) endoscopy. A prospective, randomized controlled trial was done on 199 patients undergoing upper GI endoscopy. On arrival, their anxiety levels were assessed using state and trait scores and various physiological parameters such as HR, BP, and SpO 2 . Patients were randomly divided into three groups: Group I of 67 patients who were made to listen prerecorded Vedic chants for 10 min, Group II consisting of 66 patients who listened to Indian classical instrumental music for 10 min, and Group III of 66 controls who remained seated for same period in the same environment. Thereafter, their anxiety state scores and physiological parameters were reassessed. A significant reduction in anxiety state scores was observed in the patients in Group I (from 40.4 ± 8.9 to 38.5 ± 10.7; P < 0.05) and Group II (from 41.8 ± 9.9 to 38.0 ± 8.6; P < 0.001) while Group III controls showed no significant change in the anxiety scores. A significant decrease in systolic BP ( P < 0.001), diastolic BP ( P < 0.05), and SpO 2 ( P < 0.05 was also observed in Group II. Listening to Vedic chants and Indian classical instrumental music has beneficial effects on alleviating anxiety levels induced by apprehension of invasive procedures and can be of therapeutic use.

To describe the results of a long-term follow-up of Bartter syndrome patients treated with different drugs. Patients were diagnosed according to clinical and laboratory data. Treatment protocol was potassium supplementation, sodium, spironolactone, and non-steroidal anti-inflammatory drug. Patients who developed proteinuria were converted to angiotensin conversion enzyme inhibitor. The variables evaluated for each drug were Z-score for weight and stature, proteinuria, creatinine clearance, gastrointestinal complaints, amount of potassium supplementation, serum potassium and bicarbonate levels, and findings of upper digestive endoscopy. 20 patients were included. Follow-up was 10.1 ± 5.2 years. 17 patients received indomethacin for 5.9 ± 5.3 years; 19 received celecoxib, median of 35 months; and five received enalapril, median of 23 months. During indomethacin, a statistically significant increase was observed in the Z-score for stature and weight, without a change in the creatinine clearance. Seven of 17 patients had gastrointestinal symptoms, and upper digestive endoscopy evidenced gastritis in three patients and gastric ulcer in four patients. During celecoxib use, a significant increase was detected in the Z-score for stature and weight and a reduction of hyperfiltration; seven patients presented gastrointestinal symptoms, and upper digestive endoscopy evidenced mild gastritis in three. During enalapril use, no significant changes were observed in the Z-score for stature, weight and creatinine clearance. The conversion to enalapril resulted in a significant reduction in proteinuria. The authors suggest starting the treatment with celecoxib, and replacing by ACEi if necessary, monitoring the renal function. The safety and efficacy of celecoxib need to be assessed in larger controlled studies. Copyright © 2014 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

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.

Patients with gastroesophageal reflux disease (GERD) also have various extra-esophageal symptoms. Laryngopharyngeal reflux disease (LPRD) is a subtype of GERD associated with globus sensation, but proton pump inhibitor (PPI) therapy achieves disappointing results. This study investigated esophageal motility in GERD patients with globus sensation who were resistant to PPI therapy. The subjects were 350 patients with globus sensation. All patients underwent both laryngoscopy and upper gastrointestinal endoscopy to exclude organic disease. After 4 weeks of treatment with rabeprazole sodium (20 mg daily), the patients were divided into PPI-responsive and PPI-resistant groups. Then we investigated esophageal motility in the PPI-resistant group by a multichannel intraluminal impedance and manometry study. A total of 119 patients (55.6%) were resistant to PPI therapy, among whom 57 patients (47.9%) had abnormal esophageal motility. They included 36 patients (66.4%) with ineffective esophageal motility, 9 patients (14.4%) with achalasia, 6 patients (9.6%) with diffuse esophageal spasm, 5 patients (8%) with nutcracker esophagus, and 1 patient (1.6%) with hypertensive lower esophageal sphincter. There were significant differences of upper esophageal sphincter pressure and esophageal body peristalsis between the patients with PPI-resistant LPRD and healthy controls matched for age and sex. Among patients with PPI-resistant LPRD, 47.9% had abnormal esophageal motility.

Closure of the duodenal stump using a stapling device is commonly applied in Roux-en-Y reconstruction after gastrectomy. However, serious and possibly fatal duodenal stump perforation can develop in extremely rare cases. We describe a case of subtotal gastrectomy with Roux-en-Y reconstruction followed by repeated duodenal stump perforations. A 79-year-old man with a long history of diabetes and hypertension was admitted to our institution with epigastralgia and right hypochondralgia. Computed tomography and an upper gastrointestinal imaging series revealed remarkable wall thickening of the gastric antrum and corpus. Upper endoscopy also showed a giant ulcerative lesion in the same area. The lesion was confirmed by histology to be poorly differentiated adenocarcinoma. The patient underwent open subtotal gastrectomy with Roux-en-Y reconstruction. However, duodenal stump perforation occurred repeatedly on postoperative days 1, 3, and 19, which caused peritonitis. The patient was kept alive through duodenal stump repair, an additional resection using a stapling device, and repeated drainage treatments; but he suffered considerable morbidity due to these complications. We report a case of a life-threatening duodenal stump perforation after subtotal gastrectomy, highlighting lessons learned from the profile and clinical course. Abdominal surgeons should be aware of the possibility of this serious complication of duodenal stump perforation, and be able to perform immediate interventions, including life-saving reoperation.

Knowledge of quality measures in endoscopy among trainees is unknown. To assess knowledge of endoscopy-related quality indicators among U.S. trainees and determine whether it improves with a Web-based intervention. Randomized, controlled study. Multicenter. This study involved trainees identified from the American Society for Gastrointestinal Endoscopy membership database. Participants were invited to complete an 18-question online test. Respondents were randomized to receive a Web-based tutorial (intervention) or not. The test was readministered 6 weeks after randomization to determine the intervention's impact. Baseline knowledge of endoscopy-related quality indicators and impact of the tutorial. A total of 347 of 1220 trainees (28%) completed the test; the mean percentage of correct responses was 55%. For screening colonoscopy, 44% knew the adenoma detection rate benchmark, 42% identified the cecal intubation rate goal, and 74% knew the recommended minimum withdrawal time. A total of 208 of 347 trainees (59%) completed the second test; baseline scores were similar for the tutorial (n = 106) and no tutorial (n = 102) groups (56.4% vs 56.9%, respectively). Scores improved after intervention for the tutorial group (65%, P = .003) but remained unchanged in the no tutorial group. On multivariate analysis, each additional year in training (odds ratio [OR] 2.3; 95% confidence interval [CI], 1.5-3.4), training at an academic institution (OR 2.6; 95% CI, 1.1-6.3), and receiving the tutorial (OR 3.2; 95% CI, 1.7-5.9) were associated with scores in the upper tertile. Low response rate. Knowledge of endoscopy-related quality performance measures is low among trainees but can improve with a Web-based tutorial. Gastroenterology training programs may need to incorporate a formal didactic curriculum to supplement practice-based learning of quality standards in endoscopy.

Portal hypertension secondary to portal vein obstruction following liver transplant occurs in 5%-10% of children. Jejunal varices are uncommon in this group. We present a case series of children with significant GI blood loss, negative upper endoscopy, and jejunal varices detected by CE. Case series of patients who had CE for chronic GI blood loss following liver transplantation. Three patients who had their initial transplants at a median age of 7 months were identified at our institution presenting at a median age of 8 years (range 7-16 years) with a median Hgb of 2.8 g/dL (range 1.8-6.8 g/dL). Upper endoscopy was negative for significant esophageal varices, gastric varices, and bleeding portal gastropathy in all three children. All three patients had significant jejunal varices noted on CE in mid-jejunum. Jejunal varices were described as large prominent bluish vessels underneath visualized mucosa, one with evidence of recent bleeding. The results led to venoplasty of the portal vein in two patients and a decompressive shunt in one patient with resolution of GI bleed and anemia. CE is useful to diagnose intestinal varices in children with portal hypertension and GI bleeding following liver transplant. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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.

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.

There are few data in the literature on microscopic gastritis and colitis in the pediatric population. The diagnosis is often made after the occurrence of complications. We report the case of a 10.5 year-old girl for whom the diagnosis was made several years after the initial symptoms. Test for infections, inflammation, and auto-immunity yielded normal results. Upper endoscopy and colonoscopy revealed an abnormal mucosa. However, histology showed microscopic inflammation and fibrotic lesions in the lamina propria, and a thick subepithelial collagenous band. This led to the diagnosis of collagenous gastritis and colitis. Budesonide treatment resulted in the cessation of diarrhea and significant weight gain. Treatment by oral budesonide indeed seems to be highly effective but relapses are frequent when the treatment is stopped. This case shows the importance of being vigilant regarding transit disorders with impact on growth kinetics. Upper endoscopy and colonoscopy need to be carried out when children have organic diarrhea with normal blood tests. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Unsedated upper gastrointestinal endoscopy (UGE) can induce patient discomfort, mainly due to a strong gag reflex. The aim was to assess the effect of a bupivacaine lozenge as topical pharyngeal anesthetic compared with standard treatment with a lidocaine spray before UGE. Ninety-nine adult outpatients undergoing unsedated diagnostic UGE were randomized to receive either a bupivacaine lozenge (L-group, n = 51) or lidocaine spray (S-group, n = 42). Primary objective was assessment of patient discomfort including acceptance of the gag reflex during UGE. The L-group assessed the discomfort significantly lower on a visual analog scale compared with the S-group (P = 0.02). There was also a significant difference in the four-point scale assessment of the gag reflex (P = 0.03). It was evaluated as acceptable by 49% in the L-group compared with 31% in the S-group. A bupivacaine lozenge compared with a lidocaine spray proved to be a superior option as topical pharyngeal anesthetic before an UGE. PMID:25374463

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

Transnasal endoscopy: Technical considerations, advantages and limitations.

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.

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.

The aim of this study was to analyze digestive hemorrhage by oesophageal varicose vein bleeding, were pharmacological and endoscopic treatments suitable are not available. This prospective study related to 50 patients admitted for oesophageal varicose vein bleeding in the service of hepato-gastro-enterology of the hospital Gabriel Touré (MALI), from June 2003 to December 2005. The patients underwent clinical examination and upper digestive endoscopy to appreciate oesophageal varicose vein and marks of bleeding. Some biological examinations (haemoglobin, hematocrit, prothrombin time) were carried out in emergency to appreciate systemic repercussion of the haemorrhage. Our results showed that by oesophageal varicose vein bleeding represented 2.5% of the hospitalizations during the period of study.The average age of the patients was 37 years with, a sex ratio of 6.1% in favour of men. Antecedent of jaundice was frequently found (54%). The main cause of the varicose vein was cirrhosis. Mortality was 48%. The prognosis was not significantly improved by blood transfusion. At the end of this study, the stress must be laid on the HBV prevention because HBV is the main cause of chronic liver diseases.

To evaluate the proportion of children with moderate to severe iron-deficiency anemia who have associated celiac disease. This cross-sectional analytical study was conducted among children aged 1 to 12 years of age with moderate-to-severe iron deficiency anemia and control children without anemia. Serum IgA-tissue trans-glutaminase levels were assessed in both cases and controls. All children with positive celiac serology underwent upper gastrointestinal endoscopy and duodenal biopsy; biopsy finding of Marsh grade 3 was considered positive for celiac disease. There were 152 anemic children and 152 controls with mean (SD) hemoglobinof 7.7 (1.8) and 12.2 (0.74) g/dL, respectively. 16 (10.5%) cases and 3 (2%) control patients had positive serology for celiac disease [OR (95% CI) 5.33 (1.52-18.67), P=0.007]. Six (3.9%) children with iron-deficiency anemia and none of the controls had biopsy features diagnostic of celiac disease. In the Northern Indian tertiary-care hospital outpatient setting, Celiac disease was associated with 4% of children presenting with moderate-to-severe anemia.

Gastric metastases from renal cell carcinoma (RCC) are rare with few cases described in the literature. We report the history of a 77-year-old male patient who underwent a right radical nephrectomy because of RCC. Two years after the diagnosis, he presented with abdominal pain and evidence of upper gastrointestinal bleeding. Esophagogastroduodenoscopy revealed a 3 cm, ulcerated, pedunculated polypoid mass in the stomach that was removed with a diathermic snare. Histology with immunohistochemistry confirmed the diagnosis of metastatic RCC. Three months of follow-up revealed no further episode of rebleeding. We identified (using the PubMed database) 44 cases of gastric metastasis of RCC in the literature; the majority were male patients, with mean age at presentation of 67.2 years and average time from nephrectomy to presentation of gastric metastases of 6.9 years. Our results suggest that endoscopy may have an important role in the treatment of these patients for controlling the complications and/or improving mean survival time. Gastric metastases of RCC are rare but should be considered even many years after diagnosis and treatment of RCC, particularly in patients with gastrointestinal symptoms.

This prospective study aimed to compare serology for Helicobacter pylori with two, symptom questionnaires in screening patients before direct access endoscopy. Methods were compared in terms of the number of endoscopies saved and pathology missed in 315 patients referred to a gastroenterology unit by 65 local GPs. The serology used was based on an acid glycine extract of H pylori. One in-house questionnaire was based on the Glasgow dyspepsia (GLADYS) system and the other questionnaire was that reported by Holdstock et al. A cut off point of 6.3 U/ml for H pylori serology was selected for screening patients (97% sensitive and 75% specific). Serology was combined with a history of NSAID usage in determining who should have endoscopy. For the in-house questionnaire, a cut off score of more than 8 out of a possible maximum of 18 was chosen, after prior evaluation in 118 patients referred for direct access endoscopy (the sensitivity for detection of peptic ulcer was 88%, specificity 61%). A cut off score of more than 412 was used for the Holdstock questionnaire. In patients under 45 years, serology detected more peptic ulcers than the in-house questionnaire and the Holdstock questionnaire (27/28 v 24/28, NS and v 20/28, p < 0.05 respectively). The Holdstock questionnaire saved significantly more endoscopies than the other two methods (76/149 v 57/149 for the in-house questionnaire, p = 0.05 and 59/149 for serology, p = 0.05). In all age groups combined, serology was significantly better than the in-house and Holdstock questionnaires at detecting peptic ulcers and gastric cancer (61/63, 52/63, p<0.02, and 50/63, p<0.01 respectively). But serology saved significantly fewer endoscopies (89/315, 135/315, p<0.005, and 119/315, p<0.05 respectively). Serology was inferior to the Holdstock questionnaire at detecting severe oesophagitis. It is concluded that serology is the method of choice in screening before direct access upper gastrointestinal endoscopy in those under 45 years. It best combines a high sensitivity for peptic ulcer disease with a large reduction in unnecessary negative endoscopies.

The present study aimed to investigate the efficacy of endoscopy in the treatment of post-shunt placement for slit ventricle syndrome (SVS). Endoscopic surgery was performed on 18 patients with SVS between October 2004 and December 2012. Sex, age, causes of the hydrocephalus, ventricular size and imaging data were collected and analyzed. All patients were divided into two groups according to ventricular size and underwent endoscopic surgeries, including endoscopic third ventriculostomy (ETV), endoscopic aqueductoplasty and cystocisternostomy. All treated patients were observed postoperatively for a period of 2 to 3 weeks, and outpatient follow-up was subsequently scheduled for >12 months. Clinical results, including catheter adherence, shunt removal and complications, were analyzed during the follow-up period. The success rate of endoscopic surgery was indicated to be 82.7%. Syndromes caused by aqueductal stenosis in 15 patients who underwent ETV were relieved; however, syndromes in the 3 patients with cerebral cysticercosis, suprasellar arachnoid cysts, pinea larea glioma and communicating hydrocephalus, respectively, were not relieved and underwent shunt placement again. Brain parenchyma, choroid plexus and ependymal tissue were the predominant causes for catheter obstruction and the obstruction rate was indicated to be 77.8% (14/18). Complications, such as pseudobulbar paralysis, infection and intraventricular hemorrhage arose in 3 patients. The present study indicates that endoscopic treatments are effective and ETV may be considered as a recommended option in the treatment of post-shunt placement SVS in hydrocephalus patients.

Chromoendoscopy and magnification endoscopy in Barrett's esophagus.

Connor, Michael J; Sharma, Prateek

Chromoendoscopy and magnification endoscopy appear to be a valuable adjuncts for the detection and classification of BE. These techniques may also prove to be useful aids in surveillance protocols for identifying dysplastic epithelium or early cancer within a segment of BE. Ideally, the use of these techniques would enable the endoscopist to rule in or out the presence of IM and of dysplastic or cancerous epithelium by obtaining only a minimal number of targeted biopsy specimens, or potentially performing no biopsies at all. This could transform upper endoscopy into a much more effective screening and surveillance tool for BE. Several problems currently exist for the use of chromoendoscopy for BE. Results of studies reporting the accuracy of chromoendoscopy remain mixed,and are likely explained by the wide range of techniques and materials used in the investigations. Staining adds several steps, and likely several minutes, to an upper endoscopy. Staining within the esophagus is often patchy and uneven. In addition, poor spraying technique exaggerates the irregular uptake by the mucosa. There is a high false-positive rate when staining gastric-type epithelium and denuded epithelium. Areas of dysplasia or cancer may take up stain in an irregular manner, or may not stain at all. Chromoendoscopy is a relatively new technique in the management of BE and depends on the skill and experience of the endoscopist. Magnification, however, only allows the endoscopist to observe small areas of mucosa at a time, increasing the overall complexity and length of the procedure. The learning curve for this procedure is relatively short, however, and endoscopists can usually become proficient in the technique quickly. Currently, the greatest body of literature exists concerning the use of methylene blue for diagnosing BE. At the present time, chromoendoscopy and magnification endoscopy appear to be most beneficial in detecting IM in short segments of esophageal columnar-appearing mucosa. If used consistently by practicing physicians, the accuracy of biopsies for IM could be improved. If endoscopic ablative therapy for HGD and early adenocarcinoma becomes accepted, sensitive methods of detecting residual BE after ablation will be needed to help guide additional endoscopic therapy. Chromoendoscopy and magnification endoscopy could prove helpful in this setting. Further research in this field remains to be performed. As a first step, a uniform classification system for staining and magnification patterns should be devised. If investigators can reach a consensus, and validate classification, terminology, and pattern-types, future studies could be performed using "common and similar language." More controlled investigations with larger numbers of patients must be performed before tissue staining and magnification endoscopy become a part of the practicing endoscopist's armamentarium. The ultimate aims of chromoendoscopy and magnification endoscopy in the setting of BE are to show improved outcomes--namely, early detection of cancer and improved survival rates. These goals have not yet been realized and meeting them will require well-designed studies in the future.

Esophageal involvement, which causes stricture, is a complication in epidermolysis bullosa. This causes dysphagia and malnutrition and leads to deterioration of skin lesions in these patients. The charts of 11 patients with epidermolysis bullosa and esophageal stricture who were included into dilatation program between 2003 and 2015 were retrospectively reviewed. Seven of the patients were female and four were male. The median age was 14 (2-32) years. The mean body weight of patients was 27.8 (9-51) kg. The location and number of strictured parts of the esophagus were previously evaluated with upper gastrointestinal contrast study and after that flexible endoscopy was used for dilatation. Eight patients had middle esophageal, three patients had proximal esophageal and one of them had both proximal and middle esophageal strictures. The strictures were dilated 56 times in total (mean 5 times). One patient underwent gastrostomy and was medically followed-up after a perforation occurrence during the dilatation procedure. In a 32-year-old female patient, colon interposition was performed after four dilatations since optimal nutritional and developmental status could not be achieved. The dilatation program of nine patients is still in progress. Seven of them can easily swallow solid food but two of them have some difficulties in swallowing between dilatations. One patient rejected the program and quitted, while one patient refused colon interposition and died because of complications related to amyloidosis during the dilatation program. After resolution of the swallowing problem, skin lesions were observed to heal quickly. Epidermolysis bullosa is a rare cause of dysphagia. Esophageal balloon dilatation with flexible endoscopy is a safe and efficient method in patients with this condition. © 2016 International Society for Diseases of the Esophagus.

Minimal change esophagitis (MCE) is a reflux disease without mucosal breaks, known to be partially associated with abnormal gastric motor function. Electrogastrography (EGG) is commonly applied to assess gastric motor function in a noninvasive fashion. We aimed to determine the relationship between MCE and gastric myoelectrical activity (GME) recorded on EGG in children. We retrospectively assessed the records of 157 children without underlying disease who underwent both EGG and upper gastrointestinal endoscopy at Gachon University Gil Medical Center between January 2010 and June 2015. The children were stratified according to the appearance of the esophagus (normal vs. MCE). Between-group differences in EGG parameters and their correlation with each MCE finding were statistically analyzed. Only the power ratio, one of the EGG parameters analyzed, differed significantly between the two groups (MCE, 1.68±3.37 vs. normal, 0.76±1.06; p <0.05), whereas the other parameters, such as dominant frequency, dominant power, and the ratio of abnormal rhythm, showed no differences. Among children with MCE, significant correlations were noted between erythema and power ratio ( p <0.05), friability and postprandial dominant frequency ( p <0.05), and edema and/or accentuation of mucosal folds and pre-prandial frequency ( p <0.05). Helicobacter pylori infection correlated with postprandial arrhythmia (MCE, 33.59±15.52 vs. normal, 28.10±17.23; p <0.05). EGG parameters did not differ between children with normal esophagus and those with biopsy-proven chronic esophagitis. In children with MCE, gastric dysmotility may affect the development of MCE, manifesting as EGG abnormalities. H. pylori infection may also affect GME. However, larger prospective investigations are needed to confirm these findings.

Background and study aim  Barrett's esophagus (BE)-associated dysplasia is an important marker for risk of progression to esophageal adenocarcinoma (EAC) and an indication for endoscopic therapy. However, BE surveillance technique is variable. The aim of this study was to assess the effect of dedicated BE surveillance lists on dysplasia detection rate (DDR). Patients and methods  This was a prospective study of patients undergoing BE surveillance at two hospitals - community (UHL) and upper gastrointestinal center (GSTT). Four endoscopists (Group A) were trained in Prague classification, Seattle protocol biopsy technique, and lesion detection prior to performing BE surveillance endoscopies at both sites, with dedicated time slots or lists. The DDR was then compared with historical data from 47 different endoscopists at GSTT and 24 at UHL (Group B) who had undertaken Barrett's surveillance over the preceding 5-year period. Results  A total of 729 patients with BE underwent surveillance endoscopy between 2007 and 2012. There was no significant difference in patient age, sex, or length of BE between the two groups. There was a significant difference in detection rate of confirmed indefinite or low grade dysplasia and high grade dysplasia (HGD)/EAC between the two groups: 18 % (26 /142) Group A vs. 8 % (45/587) in Group B ( P  < 0.001). Documentation of Prague criteria and adherence to the Seattle protocol was significantly higher in Group A. Conclusion  This study demonstrated that a group of trained endoscopists undertaking Barrett's surveillance on dedicated lists had significantly higher DDR than a nonspecialist cohort. These findings support the introduction of dedicated Barrett's surveillance lists. © Georg Thieme Verlag KG Stuttgart · New York.

Introduction: Gastric cancer (GC) is the fourth most common type of neoplasm and the second cause of malignancy-related death across much of the world. Complex multi-factorial processes are involved in its genesis, classified in two determinant clusters: non-genetic and genetic . Variation in CDH1 gene expression may play an important role in increasing risk of diffuse and intestinal subtypes of GC. This tumor suppressor gene, located on chromosome 16q22.1, encodes a trans membrane glycoprotein called epithelial cadherin (E-cadherin). Materials and Methods: In this historical cohort study, from June 2004 to Journey 2005 we collected 50 samples from Kurdish patients with stage II pathologically diagnosed gastric cancer that underwent surgery. Tumor tissues were paraffin-embedded along with 54 control samples from non-ulcer dyspepsia (NUD) cases undergoing upper gastrointestinal endoscopy. Three biopsies were captured by endoscopy from each individual’s gastric antrum. Result: The mean age of the patients was 59.5±2 years. Some 23 cases (53.4%) had the CC genotype, 19 AC and 1 AA. H.pylori infection was noted in 30 patients (69%). Survival rates of gastric cancer patients were 90.7% in the first year, 39.5% in the second year and 6.9% in the third year. Female patients had higher survival rates (P=0.004). Conclusion: In this study we found that frequencies of -160(C>A) CDH1 genotypes were not comparable in H.pylori-infected and H.pylori-uninfected subjects in both case and control groups. These findings suggest that -160 (C>A) CDH1 polymorphism is not related with H.pylori infection susceptibility. In addition we found no significant relationship between the CDH1 -160(C/A) promoter polymorphism with predisposition to gastric cancer. Creative Commons Attribution License

Gastroesophageal reflux disease (GERD) is an emerging disease, and can impair quality of life and sleep. This study aimed to investigate whether GERD patients with different timings of reflux symptoms have different clinical characteristics. This study prospectively enrolled individuals who underwent upper gastrointestinal endoscopy during a health checkup. Each participant completed all questionnaires including Reflux Disease Questionnaire, Nighttime GERD questionnaire, Pittsburg Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory. Combined reflux was defined as the timing of reflux symptoms occurring at both daytime and nighttime. A total of 2604 participants were enrolled. Of them, 651 symptomatic GERD patients, according to the Reflux Disease Questionnaire score, were recruited for final analysis. Of them, 224 (34.4%) had erosive esophagitis on endoscopy. According to the timing of reflux symptoms, 184 (28.3%) were assigned to the daytime reflux group, 71 (10.9%) to the nighttime reflux group, and 396 (60.8%) to the combined reflux group. In post hoc analysis, the combined reflux group had a significantly higher Reflux Disease Questionnaire score than the daytime reflux group (p < 0.0001). Combined and nighttime reflux groups had higher body mass index and longer duration (> 12 years) of education than the daytime reflux group (p < 0.05). There was no difference in Pittsburg Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory scores among three groups. GERD patients with combined daytime and nighttime reflux of have more troublesome symptoms than those with daytime reflux. GERD patients with different timings of reflux symptoms have different clinical characteristics in terms of body mass index and duration of education, but not in terms of esophageal inflammation, quality of sleep, and psychosocial status.

Increased esophageal sensitivity and impaired mucosal integrity have both been described in patients with gastroesophageal reflux disease, but the relationship between hypersensitivity and mucosal integrity is unclear. The aim of the present study was to investigate acid sensitivity in patients with erosive and nonerosive reflux disease and control subjects to determine the relation with functional esophageal mucosal integrity changes as well as to investigate cellular mechanisms of impaired mucosal integrity in these patients. In this prospective experimental study, 12 patients with nonerosive reflux disease, 12 patients with esophagitis grade A or B, and 11 healthy control subjects underwent an acid perfusion test and upper endoscopy. Mucosal integrity was measured during endoscopy by electrical tissue impedance spectroscopy and biopsy specimens were analyzed in Ussing chambers for transepithelial electrical resistance, transepithelial permeability and gene expression of tight junction proteins and filaggrin. Patients with nonerosive reflux disease and esophagitis were more sensitive to acid perfusion compared with control subjects, having a shorter time to perception of heartburn and higher perceived intensity of heartburn. In reflux patients, enhanced acid sensitivity was associated with impairment of in vivo and vitro esophageal mucosal integrity. Mucosal integrity was significantly impaired in patients with esophagitis, displaying higher transepithelial permeability and lower extracellular impedance. Although no significant differences in the expression of tight junction proteins were found in biopsies among patient groups, mucosal integrity parameters in reflux patients correlated negatively with the expression of filaggrin. In conclusion, sensitivity to acid is enhanced in patients with gastroesophageal reflux disease, irrespective of the presence of erosions, and is associated with impaired esophageal mucosal integrity. Mucosal integrity of the esophagus is associated with the expression of filaggrin. Copyright © 2014 the American Physiological Society.

After thermal ablation of Barrett's esophagus (BE), stricture formation is reported in 5 to over 10% of patients. The question arises whether submucosal fluid injection prior to ablation may lower the risk of stricture formation. The aim of the present study was to evaluate the efficacy and safety of the new technique of Hybrid-APC which combines submucosal injection with APC. Patients who had a residual BE segment of at least 1 cm after endoscopic resection of early Barrett's neoplasia underwent thermal ablation of BE by Hybrid-APC. Prior to thermal ablation, submucosal injection of sodium chloride 0.9% was carried out using a flexible water-jet probe (Erbejet 2; Erbe Elektromedizin, Tuebingen, Germany). Check-up upper GI endoscopy was carried out 3 months after macroscopically complete ablation including biopsies from the neo-Z-line and the former BE segment, and recording of stricture formation. From May 2011 to November 2012, a total of 60 patients (pt) were included in the study [55 pt male (92%); mean age 62 ± 9 years, range 42-79]. Ten patients were excluded from the study. In the remaining 50 pt, Hybrid-APC ablation and check-up endoscopy at 3 months were carried out. Forty-eight out of 50 pt (96%; ITT: 49/60, 82%) achieved macroscopically complete remission after a median of 3.5 APC sessions [SD 2.4; range 1-10]. Freedom from BE was histopathologically observed in 39/50 patients (78%). There was one treatment-related stricture (2%). Minor adverse events of Hybrid-APC were observed in 11 patients (22%). According to this pilot series, Hybrid-APC was effective and safe for BE ablation in a tertiary referral center. The rate of stricture formation was only 2%. Further studies are required to confirm the present results. DRKS00003369.

(1) The number of endoscopic examinations performed is rising. Epidemiological data and the workload of well developed units show that annual requirements per head of population are approaching: Upper gastrointestinal 1 in 100 Flexible sigmoidoscopy 1 in 500 Colonoscopy 1 in 500 ERCP 1 in 2000 (2) Open access endoscopy to general practitioners is desirable and increasingly sought. For a district general hospital serving a population of 250,000, this workload entails about 3500 procedures annually, performed during 10 half day routine sessions plus emergency work. (3) High standards of training and experience are needed by all staff, who must work in purpose built accommodation designed to promote efficient and safe practice. (4) The endoscopy unit should be adjacent to day care facilities and near the x ray department. There should be easy access to wards. (5) An endoscopy unit needs at least two endoscopy rooms; a fully ventilated cleaning/disinfection area; rooms for patient reception, preparation, and recovery; and accommodation for administration, storage, and staff amenities. (6) The service should be consultant based. At least 10 clinical sessions are required, made up of six or more consultant sessions and two to four clinical assistant, hospital practitioner, or staff specialist sessions. Each consultant should be expected to commit at least two sessions weekly to endoscopy. Extra consultant sessions may be needed to provide an efficient service. (7) A specially trained nursing sister (grade G or H) and five other endoscopy nurses are needed to care for the patients; their work may be supplemented by care assistants. (8) A new post of endoscopy department assistant (analogous to an operating department assistant) is proposed to maintain and prepare instruments, and to give technical assistance during procedures. (9) A full time secretary should be employed. Records, appointments, and audit should be computer based. (10) ERCP needs the collaboration of an interventional radiologist working with high quality x ray equipment in a specially prepared radiology screening room. This facility may need to serve more than one hospital. (11) A gastrointestinal measurement laboratory can conveniently be combined with the endoscopy unit. In some hospitals one or more gastrointestinal measurement technicians may staff this laboratory. (12) An endoscopy unit is a service department analogous to a radiology department. It needs an annual budget.

Studies on the role of duodenal bulb biopsy (DBB) in coeliac disease (CD) evaluation have increased in recent years; growing evidence suggests that the disease can present solely in the duodenal bulb. Moreover, recent CD guidelines recommend obtaining a DBB. The study aim was to examine DBB performance in children undergoing CD evaluation and to identify independent predictors of DBB performance. The authors performed a structured chart review of children aged <18 years who underwent CD evaluation between 2000 and 2010 at a large teaching hospital. The authors collected data including demographics, serology, endoscopy and histopathological findings. Predictors of DBB performance (obtained vs not obtained) were determined using multivariable logistic regression. Among 616 children who underwent endoscopy, DBB was performed in 103 children (17%, 95% CI 14% to 20%) with an increasing trend in the more recent years (2008-2010, 25%; 2004-2007, 16%; and 2000-2003, 5%, p<0.001). Three independent predictors of DBB performance were older age at endoscopy (OR 1.05 per year of age), gross gastric antral abnormalities (OR 2.81) and gross duodenal abnormalities (OR 5.55). Regarding the DBB histological findings, patchiness of CD was found in 15%. Positive Marsh III biopsy presented solely on the DBB in 6/103 (6%, 95% CI 2% to 12%) children. The authors found a significant increase in DBB performance over time, but the overall performance remains suboptimal. Improving education on obtaining a DBB for CD evaluation is crucial, especially among those children in whom DBB is more likely to be omitted.

To correlate resting and exercising endoscopic grades of laryngeal function in horses undergoing high-speed treadmill endoscopy (HSTE) using the Havemeyer grading system. To correlate dorsal displacement of the soft palate (DDSP) seen at rest with palatal function during exercise. Records of horses that underwent HSTE examination (1999-2009) were reviewed. Resting laryngeal function score and other abnormalities noted on resting endoscopy were recorded as were results of HSTE. Results of resting and exercising endoscopic findings were correlated. 281 horses underwent HSTE. There was significant correlation between grade of laryngeal function at rest (grades 1-4) and exercise (ρ=0.53, P<0.001) and between resting subgrades 3.1, 3.2 and 3.3 and exercising grades of laryngeal function (ρ=0.43, P=0.0017). DDSP was observed at rest significantly more often in horses that developed DDSP during HSTE than those without DDSP during HSTE (RR=4.1, P<0.001). The sensitivity and specificity of DDSP seen during resting endoscopy as a test for DDSP occurring during exercise were 25.5 and 95.1% respectively (positive predictive value 0.57, negative predictive value 0.83). The results of the current study support the use of the Havemeyer system for grading laryngeal function in the resting horse, and corroborate findings of previous studies correlating resting and exercising palatal abnormalities. Studies that use the presence of spontaneous DDSP during resting endoscopic examination as an inclusion criterion for investigating efficacy of treatments for DDSP are likely to have a low proportion of horses with false positive diagnoses. © 2010 EVJ Ltd.

Capturing and stitching images with a large viewing angle and low distortion properties for upper gastrointestinal endoscopy

NASA Astrophysics Data System (ADS)

Liu, Ya-Cheng; Chung, Chien-Kai; Lai, Jyun-Yi; Chang, Han-Chao; Hsu, Feng-Yi

2013-06-01

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.

Update on Functional Heartburn

PubMed Central

Yamasaki, Takahisa; O’Neil, Jessica

2017-01-01

The definition of functional heartburn has been refined over the years. It is currently described, based upon Rome IV criteria, as typical heartburn symptoms in the presence of normal upper endoscopy findings (including normal biopsies), normal esophageal pH testing, and a negative association between symptoms and reflux events. Functional heartburn is very common, affecting women more than men, and with reflux hypersensitivity makes up the majority of heartburn patients who fail twice-daily proton pump inhibitor therapy. These disorders overlap with other functional gastrointestinal disorders and are often accompanied by psychological comorbidities. Diagnosis is made by using endoscopy with esophageal biopsies, wireless pH capsule, pH-impedance monitoring, and high-resolution esophageal manometry. Additional diagnostic tools that may be of value include magnification endoscopy, chromoendoscopy, narrow-band imaging, autofluorescence imaging, mucosal impedance, impedance baseline values, and histopathology scores. Functional heartburn is primarily treated with neuromodulators. Psychological intervention and complementary and alternative medicine may also play important roles in the treatment of these patients.

Endoscopy and histopathology in the examination of the nasal cavity in dogs.

PubMed

Sapierzyński, R; Zmudzka, M

2009-01-01

Nasal diseases of chronic nature are a common clinical complaint in canine practice. However, precise diagnosis in these cases is often difficult and require the use of various, additional diagnostic methods. The aim of this study was to estimate the occurrence of diseases of the upper respiratory tracts in dogs, and to evaluate the usefulness of endoscopy in the diagnostic process as a method of obtaining a final diagnosis. In the group of dogs in which rhinoscopy was performed, the most common final diagnoses were nonspecific chronic rhinitis, followed by neoplasms and infectious rhinitis. It can be concluded that rhinoscopy should be considered mainly as a preliminary method of inspection of the nasal cavity, helpful in obtaining the most representative tissue specimen/specimens for histopathology. In some cases, especially foreign objects and congenital abnormalities rhinoscopy can give the possibility of obtaining a final diagnosis. However, even in these situations and also when any macroscopic lesion is found during endoscopy, microscopic examination of the mucosa specimen should be performed.

Nerve Injuries in Gynecologic Laparoscopy.

Abdalmageed, Osama S; Bedaiwy, Mohamed A; Falcone, Tommaso

2017-01-01

Nerve injuries during gynecologic endoscopy are an infrequent but distressing complication. In benign gynecologic surgery, most of these injuries are associated with patient positioning, although some are related to port placement. Most are potentially preventable with attention to patient placement on the operating room bed and knowledge of the relative anatomy of the nerves. The highest risk group vulnerable to these injuries includes women who have extreme body mass index and those with longer surgical times in the Trendelenburg position. Upper and lower limb peripheral nerves are the most common nerves injured during gynecologic endoscopy. These injuries can result in transient or permanent sensory and motor disabilities that can interrupt patient recovery in an otherwise successful surgery. Numerous strategies are suggested to reduce the frequency of nerve injuries during gynecologic endoscopies. Proper patient positioning and proper padding of the pressure areas are mandatory to prevent malposition-related nerve injuries. Anatomic knowledge of the course of nerves, especially ilioinguinal and iliohypogastric, nerves can minimize injury. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

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.

Background and study aims  Screening for esophageal and gastric varices is indicated for patients with portal hypertension or cirrhosis. Typically, conventional endoscopy is used; however, the need for sedation increases the costs and risks, especially in cirrhotic patients. Use of transnasal endoscopy with an ultrathin endoscope enables study of the upper gastrointestinal tract without the need for sedation. The objective of this study is to evaluate the feasibility of transnasal endoscopy in screening for esophageal and gastric varices in patients with chronic liver disease. Patients and methods  This was a prospective study in which transnasal endoscopy was carried out in patients with cirrhosis or portal hypertension who had indications for screening of esophageal and gastric varices. The following variables were evaluated: demographical data, duration of procedure, patient tolerance and acceptance, adverse events (AEs), endoscopic findings and interobserver agreement related to portal hypertension alterations ( kappa index). Results  A total of 50 patients entered the study. The most common cause of liver disease was chronic viral hepatitis (66 %). Among the cirrhotic patients, most of the patients were Child-Pugh A (74 %). In 5 patients (10 %), nasal intubation was not possible. Two patients (4 %) experienced minor epistaxis. Tolerance was excellent or good in 92 % according with a visual analogic scale. In 16 patients (32 %), esophageal varices were detected and in 2 patients (4 %) gastric varices were detected. The mean duration of the procedure was 7 minutes. Conclusions  Transnasal endoscopy is feasible, effective and well tolerated for screening of esophageal and gastric varices in patients with chronic liver disease. It can be performed in outpatient clinics safely and without the use of sedation. PMID:28691048

The goal of the present study was to establish the occurrence of structural disorders in the larynx and pharynx during treadmill exercise tests in horses diagnosed with Equine Asthma (EA). Investigation was performed in 29 horses, patients of the Equine Clinic of the Warsaw University of Life Sciences in Poland, admitted with poor exercise performance. Upper and lower airway examinations were performed in all patients revealing both mild to moderate Equine Asthma (13 horses), and no lower airway abnormalities (16 animals). In the group of horses with EA, 11 did not have structural disorders of the pharynx and larynx at rest. During exercise two horses were free of abnormalities, while 11 had structural disorders, eight of them solely in the pharynx, two in the larynx, and one in both the pharynx and larynx. In the non- asthmatic group, 11 horses had no structural disorders during resting endoscopy. Endoscopy performed during exercise revealed disorders of the larynx in 10 horses, of the pharynx in three horses, and in both the larynx and pharynx in the remaining three horses. horses with diagnosed EA frequently have disorders of the pharynx during treadmill exercise tests, while without EA, often have disorders of the larynx. Endoscopy of upper airways during exercise testing is a valuable tool in the diagnosis of poor performance in horses with lower airway inflammatory disease.

There has been a drive to raise the standard of management of acute upper gastrointestinal bleeding (AUGIB) in the UK, including three previous audits, sponsored by the British Society of Gastroenterology (BSG). To review the results of the latest BSG/National Health Service (NHS) England national survey of endoscopy services in England between 2014 and 2015. All NHS hospitals accepting acute admissions in England (168) were invited to respond to the survey. Overall, 142 hospitals (84%) returned data. 85% of hospitals used a validated risk assessment score at the time of patient's admission. While 80% of hospitals provided a 24/7 endoscopy service for unstable patients, and another 10% were in network to provide an acute service, only 60% performed an endoscopy within 24 hours for stable acute admissions or inpatients with AUGIB. 11% of hospitals operated an out-of-hours ad hoc rota. 43% felt that pressure from routine work affected their ability to offer a next-day oesophagogastroduodenoscopy service, while 20% of hospitals struggled to recruit endoscopists. 28% of units reported that the previous national audit performed in 2013 had a positive influence on service development. This survey has revealed significant deficiencies in provision of services for patients with AUGIB in England, without a significant increase in number of hospitals providing an emergency AUGIB service since the last national audit in 2013.

It's been tested with the technique of the questionnaire/interview on 80 outpatients who underwent in the month of September 2014 to endoscopic examinations of the gastrointestinal tract. The patients were divided into 2 groups of 40 patients: group 1 was administered before the questionnaire and subsequently the interview was conducted, on the contrary on the group 2 was administered before the interview and subsequently the questionnaire. The results of the two groups were compared using the inter-rater agreement. It was also evaluated the internal consistency of the questions. The results show that the instrument is experienced as simple and quick to use for patients. Data analysis allowed us to conclude that the Italian translation is valid and consistent. In the phase of the interview there were some aspects that suggest, in a development of this tool, some changes that could increase the accuracy and informational content. The Italian version of the questionnaire GHAA-9m has good validity, reliability, and shows property valuation comparable to those of the American version and can therefore be used in daily practice Digestive Endoscopy.

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%).

Although digital rectal examination is an established part of physical examinations in patients with acute gastrointestinal bleeding, clinicians are reluctant to perform a rectal examination. We intended to assess whether rectal examination affects the clinical management decision in these patients. We performed a single-center, retrospective, cross-sectional study using data from electronic health records of patients aged ≥18 years presenting to the emergency department with acute gastrointestinal bleeding. Hospital admissions, intensive care unit admissions, gastroenterology consultation, initiation of medical therapy (proton pump inhibitor or octreotide), and inpatient endoscopy (upper endoscopy or colonoscopy) were assessed as outcomes. Univariate and multivariate logistic regression analyses were performed. Of 1237 patients with acute gastrointestinal bleeding, 549 (44.4%) did not have a rectal examination. Patients who had a rectal examination were less likely to be admitted than patients who did not have a rectal examination (adjusted odds ratio [AOR], 0.49; 95% confidence interval [CI], 0.30-0.79; P = .004). Patients who had a rectal examination were less likely to be started on medical therapy (AOR, 0.64; 95% CI, 0.41-0.98; P = .04) and to have endoscopy (AOR, 0.64; 95% CI, 0.44-0.94; P = .02) than patients who did not have a rectal examination. Rectal examination in patients with acute gastrointestinal bleeding can assist clinicians with clinical management decision and reduce admissions, endoscopies, and medical therapy in these patients.

Pulmonary aspiration of gastric contents during routine endoscopy

DOE Office of Scientific and Technical Information (OSTI.GOV)

La France, N.D.; Cole, P.; Wolfe, E.

Radioactive tracer studies are a sensitive means to detect occult pulmonary aspiration of gastric contents. A complication of diagnostic endoscopy is aspiration of contents even in fasted patients. The authors have studied 21 hospitalized patients who underwent elective endoscopy (END) for suspected UGI pathology. Fifteen minutes before END, and prior to pharygeal anesthesia, 1 mCi Tc-99m-sulfur colloid, added to the usual 30cc of simethicone routinely administered before END, was given orally. END was performed as usual and 2 hours later anterior 100,000 count images of the chest were obtained. All the studies were interpreted without history or clinical information. Fevermore » developed within 24 hours (and septic shock in 1) in both patients with positive studies while no fever occurred in the remaining patients with negative studies (rho<.001). The authors conclude that oral radionuclide pulmonary aspiration studies may; detect aspiration not recognized by the endoscopist, reveal evidence of aspiration that preceeds adverse clinical signs and symptoms, and be influenced by systemic pre-END drugs known to affect GI secretions and motility.« less

Background Knowledge of quality measures in endoscopy among trainees is unknown. Objective To assess knowledge of endoscopy-related quality indicators among U.S. trainees and determine whether it improves with a Web-based intervention. Design Randomized, controlled study. Setting Multicenter. Participants This study involved trainees identified from the American Society for Gastrointestinal Endoscopy membership database. Intervention Participants were invited to complete an 18-question online test. Respondents were randomized to receive a Web-based tutorial (intervention) or not. The test was readministered 6 weeks after randomization to determine the intervention’s impact. Main Outcome Measurements Baseline knowledge of endoscopy-related quality indicators and impact of the tutorial. Results A total of 347 of 1220 trainees (28%) completed the test; the mean percentage of correct responses was 55%. For screening colonoscopy, 44% knew the adenoma detection rate benchmark, 42% identified the cecal intubation rate goal, and 74% knew the recommended minimum withdrawal time. A total of 208 of 347 trainees (59%) completed the second test; baseline scores were similar for the tutorial (n = 106) and no tutorial (n = 102) groups (56.4% vs 56.9%, respectively). Scores improved after intervention for the tutorial group (65%, P = .003) but remained unchanged in the no tutorial group. On multivariate analysis, each additional year in training (odds ratio [OR] 2.3; 95% confidence interval [CI], 1.5–3.4), training at an academic institution (OR 2.6; 95% CI, 1.1–6.3), and receiving the tutorial (OR 3.2; 95% CI, 1.7–5.9) were associated with scores in the upper tertile. Limitations Low response rate. Conclusion Knowledge of endoscopy-related quality performance measures is low among trainees but can improve with a Web-based tutorial. Gastroenterology training programs may need to incorporate a formal didactic curriculum to supplement practice-based learning of quality standards in endoscopy. (Gastrointest Endosc 2012;76:100–6.)

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.

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.

To validate veterans affairs (VA) administrative data for the diagnosis of nonsteroidal anti-inflammatory drug (NSAID)-related upper gastrointestinal events (UGIE) and to develop a diagnostic algorithm. A retrospective study of veterans prescribed an NSAID as identified from the national pharmacy database merged with in-patient and out-patient data, followed by primary chart abstraction. Contingency tables were constructed to allow comparison with a random sample of patients prescribed an NSAID, but without UGIE. Multivariable logistic regression analysis was used to derive a predictive algorithm. Once derived, the algorithm was validated in a separate cohort of veterans. Of 906 patients, 606 had a diagnostic code for UGIE; 300 were a random subsample of 11 744 patients (control). Only 161 had a confirmed UGIE. The positive predictive value (PPV) of diagnostic codes was poor, but improved from 27% to 51% with the addition of endoscopic procedural codes. The strongest predictors of UGIE were an in-patient ICD-9 code for gastric ulcer, duodenal ulcer and haemorrhage combined with upper endoscopy. This algorithm had a PPV of 73% when limited to patients >or=65 years (c-statistic 0.79). Validation of the algorithm revealed a PPV of 80% among patients with an overlapping NSAID prescription. NSAID-related UGIE can be assessed using VA administrative data. The optimal algorithm includes an in-patient ICD-9 code for gastric or duodenal ulcer and gastrointestinal bleeding combined with a procedural code for upper endoscopy.

Acute non-variceal upper gastrointestinal bleeding (ANVUGIB) is one of the most common medical emergencies in China and worldwide. In 2009, we published the "Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleeding" for the patients in China; however, during the past years numerous studies on the diagnosis and treatment of ANVUGIB have been conducted, and the management of ANVUGIB needs to be updated. The guidelines were updated after the databases including PubMed, Embase and CNKI were searched to retrieve the clinical trials on the management of ANVUGIB. The clinical trials were evaluated for high-quality evidence, and the advances in definitions, diagnosis, etiology, severity evaluation, treatment and prognosis of ANVUGIB were carefully reviewed, the recommendations were then proposed. After several rounds of discussions and revisions among the national experts of digestive endoscopy, gastroenterology, radiology and intensive care, the 2015 version of "Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleeding" was successfully developed by the Chinese Journal of Internal Medicine, National Medical Journal of China, Chinese Journal of Digestion and Chinese Journal of Digestive Endoscopy. It shall be noted that although much progress has been made, the clinical management of ANVUGIB still needs further improvement and refinement, and high-quality randomized trials are required in the future. © 2016 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.

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

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.

Drug induced sleep endoscopy: its role in evaluation of the upper airway obstruction and patient selection for surgical and non-surgical treatment

PubMed Central

De Vito, Andrea

2018-01-01

Sleep related breathing disorders cause obstruction of the upper airway which can be alleviated by continuous positive airway pressure (CPAP) therapy, oral devices or surgical intervention. Non-surgical treatment modalities are not always accepted by patients and in order to attain successful surgical outcomes, evaluation of the upper airway is necessary to carefully select the patients who would benefit from surgery. There are numerous techniques available to assess the upper airway obstruction and these include imaging, acoustic analysis, pressure transducer recording and endoscopic evaluation. It is essential to note that the nocturnal obstructive upper airway has limited muscle control compared to the tone of the upper airway lumen during wakefulness. Thus, if one were to attempt to identify the anatomical segments contributing to upper airway obstruction in sleep related breathing disorders; it must be borne in mind that evaluation of the airway must be performed if possible when the patient is awake and asleep albeit during drug induced sleep. This fact as such limits the use of imaging techniques for the purpose. Drug induced sleep endoscopy (DISE) was pioneered at Royal National Throat, Nose and Ear Hospital, London in 1990 and initially introduced as sleep nasendoscopy. The nomenclature and the technique has been modified by various Institutions but the core value of this evaluation technique remains similar and extremely useful for identifying the anatomical segment responsible for obstructing the upper airway during sleep in patients with sleep related breathing disorders. There have been numerous controversies that have surrounded this technique but over the last two decades most of these have been addressed and it now remains in the forefront of methods of evaluating the upper airway obstruction. A variety of sedative agents and different grading systems have been described and efforts to unify various aspects of the technique have been made. This article will look at its usefulness and advantages and will discuss some important contributions made to the field of evaluation of the upper airway using DISE. PMID:29445527

The aim of this study was to identify the incidence of upper gastrointestinal bleeding (UGIB) in the postprocedural period following transcatheter aortic valve replacement (TAVR). As TAVR moves into intermediate- and low-risk patients, it has become increasingly important to understand its extracardiac complications. The patient population undergoing TAVR have clinical and demographic characteristics that place them at significant risk of UGIB. Practical aspects of TAVR, including use of antithrombotic therapy, further increase risk of UGIB. A retrospective single-center evaluation of 841 patients who underwent TAVR between January 2005 and August 2014 was performed in conjunction with analysis of referral patterns to the gastroenterology service for UGIB at the same site. The overall risk of UGIB following TAVR was found to be 2.0% (n = 17/841). Additionally, the risk of UGIB in patients receiving triple antithrombotic therapy was found to be 10-fold greater than patients not receiving triple antithrombotic therapy (11.8% vs 1.0%). Endoscopy findings demonstrated five high-risk esophageal lesions including erosive esophageal ulcers, visible vessels at the GE junction, erosions at distal esophagus, and an actively bleeding esophageal ring that had been intubated through by the transesophageal echocardiography (TEE) probe. This large cohort study demonstrates that TAVR is associated with a moderate risk of severe UGIB. The results of this study suggest that patients on triple antithrombotic therapy are at highest risk for severe UGIB. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

To elucidate the clinicopathological characteristics of clinically early gastric cancer in the upper-third stomach and to clarify treatment precautions. A total of 683 patients with clinical early gastric cancer were enrolled in this retrospective study, 128 of whom had gastric cancer in the upper-third stomach (U group). All patients underwent a double contrast barium examination, endoscopy, and computed tomography (CT), and were diagnosed preoperatively based on the findings obtained. The clinicopathological features of these patients were compared with those of patients with gastric cancer in the middle- and lower-third stomach (ML group). We also compared clinicopathological factors between accurate-diagnosis and under-diagnosis groups in order to identify factors affecting the accuracy of a preoperative diagnosis of tumor depth. Patients in the U group were older (P = 0.029), had a higher ratio of males to females (P = 0.015), and had more histologically differentiated tumors (P = 0.007) than patients in the ML group. A clinical under-diagnosis occurred in 57 out of 683 patients (8.3%), and was more frequent in the U group than in the ML group (16.4% vs 6.3%, P < 0.0001). Therefore, the rates of lymph node metastasis and lymphatic invasion were slightly higher in the U group than in the ML group (P = 0.071 and 0.082, respectively). An under-diagnosis was more frequent in histologically undifferentiated tumors (P = 0.094) and in those larger than 4 cm (P = 0.024). The median follow-up period after surgery was 56 mo (range, 1-186 mo). Overall, survival and disease-specific survival rates were significantly lower in the U group than in the ML group (P = 0.016 and 0.020, respectively). However, limited operation-related cancer recurrence was not detected in the U group in the present study. Clinical early gastric cancer in the upper-third stomach has distinguishable characteristics that increase the risk of a clinical under-diagnosis, especially in patients with larger or undifferentiated tumors.

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.

In adults, most intussusceptions develop from a lesion, usually a benign or malignant neoplasm, and can occur at any site in the gastrointestinal tract. Intussusception in the proximal gastrointestinal tract is uncommon, and gastro-gastric intussusception is extremely rare. We present a case of gastro-gastric intussusception secondary to a primary gastric lymphoma. An 82-year-old female patient presented with acute onset chest pain and vomiting. Abdominal CT revealed a gastro-gastric intussusception. We performed upper gastrointestinal endoscopy, revealing a large gastric mass invaginated into the gastric lumen and distorting the distal stomach. Uncomplicated gastric reposition was achieved with endoscopy of the distal stomach. Histological evaluation of the gastric mass revealed a diffuse large B cell lymphoma that was treated with chemotherapy.

A novel ablation system has been introduced for rapid treatment of atrial fibrillation (AF). This system delivers duty-cycled phased radiofrequency (RF) energy via an over-the-wire catheter (PVAC® , Medtronic) to achieve pulmonary vein (PV) isolation. Lower power and depth control suggests that collateral damage might be minimized. However, no studies have investigated the potential for thermal effect and damage to the esophagus. Ninety consecutive patients undergoing PV-isolation were evaluated. Group A (48 patients) had continuous luminal esophageal temperature (LET) monitoring using a temperature probe with 3 metal electrodes located in the vicinity of the targeted PV ostia. Ablation ceased when LET exceeded 40 °C. Only patients with LET ≥ 39 °C underwent endoscopic evaluation to assess esophageal damage. Group B (42 patients) excluded LET monitoring but all patients underwent endoscopy. In Group A, 27 (56%) patients showed LET ≥ 39 °C (mean LET 40.5 °C). Endoscopy revealed esophageal alterations in 5 (8%) (3 erythema and 2 intramural bleeding). One hundred eighty-nine out of 190 (99.5%) targeted PVs were successfully isolated, with 1 PV unsuccessful due to high LET. In Group B all 165 targeted PVs (100%) were successfully isolated. Endoscopy in Group 2 revealed no esophageal alterations. Using a duty-cycled, phased RF ablation system is safe and effective to isolate PVs. No Eso alteration was documented after ablation when LET was not monitored. This suggests that the LET probe may contribute to the thermal effect. Whether the documented increments in LET are due to direct tissue heating or possible interaction between the LET probe requires further investigation. © 2010 Wiley Periodicals, Inc.

Through-the-needle microforceps are a recent addition to the EUS armamentarium for evaluation of pancreatic cystic lesions (PCLs). The main aim of this study was to assess the technical feasibility, diagnostic yield, and safety of EUS-guided microforceps biopsy for PCLs. Our electronic endoscopy database was queried to identify patients who underwent EUS-guided FNA (EUS-FNA) of PCLs and microforceps biopsies during the same procedure. A biopsy was done on the wall of the cyst with the microforceps through the 19-gauge needle, and cyst fluid was collected for cytology and carcinoembryonic antigen (CEA) levels. Adverse events were recorded per published American Society for Gastrointestinal Endoscopy criteria. Twenty-seven patients underwent EUS-FNA and microforceps biopsy of PCLs from February 2016 to July 2017. Fourteen cysts were located in the pancreatic head and/or uncinate, and 13 were located in the body and/or tail region. Microforceps biopsies were technically successful in all cases and provided a pathology diagnosis in 24 of 27 cases (yield 88.9%). Microforceps biopsies diagnosed mucinous cyst in 9 patients (33.3%), serous cystadenoma in 4 (14.8%), neuroendocrine tumor in 1 (3.7%), and benign and/or inflammatory cyst in 10 (37.1%). In 7 patients (26%), microforceps biopsy results drastically changed the diagnosis, providing diagnoses otherwise not suggested by cytology or cyst fluid CEA levels. However, cytology provided a diagnosis of mucinous cyst in 4 cases (14.8%) not detected by microforceps biopsies. No adverse events were noted. Microforceps biopsies were associated with high technical success, and an excellent safety profile and may be a useful adjunctive tool, complementing existing EUS-FNA sampling protocols for PCLs.

Background Endoscopy-assisted breast surgery (EABS) performed through minimal axillary and/or periareolar incisions is a possible alternative to open surgery for certain patients with breast cancer. In this study, we report the early results of an EABS program in Taiwan. Methods The medical records of patients who underwent EABS for breast cancer during the period May 2009 to December 2014 were collected from the Taiwan Endoscopic Breast Surgery Cooperative Group database. Data on clinicopathologic characteristics, type of surgery, method of breast reconstruction, complications and recurrence were analyzed to determine the effectiveness and oncologic safety of EABS in Taiwan. Results A total of 315 EABS procedures were performed in 292 patients with breast cancer, including 23 (7.8%) patients with bilateral disease. The number of breast cancer patients who underwent EABS increased initially from 2009 to 2012 and then stabilized during the period 2012–2014. The most commonly performed EABS was endoscopy-assisted total mastectomy (EATM) (85.4%) followed by endoscopy-assisted partial mastectomy (EAPM) (14.6%). Approximately 74% of the EATM procedures involved breast reconstruction, with the most common types of reconstruction being implant insertion and autologous pedicled TRAM flap surgery. During the six-year study period, there was an increasing trend in the performance of EABS for the management of breast cancer when total mastectomy was indicated. The positive surgical margin rate was 1.9%. Overall, the rate of complications associated with EABS was 15.2% and all were minor and wound-related. During a median follow-up of 26.8 (3.3–68.6) months, there were 3 (1%) cases of local recurrence, 1 (0.3%) case of distant metastasis and 1 (0.3%) death. Conclusion The preliminary results from the EABS program in Taiwan show that EABS is a safe procedure and results in acceptable cosmetic outcome. These findings could help to promote this under-used surgical technique in the field of breast cancer. PMID:26950469

Preclinical simulator training has the potential to decrease endoscopic procedure time and patient discomfort. This study aims to characterize the learning curve of endoscopic novices in a part-task simulator and propose a threshold score for advancement to initial clinical cases. Twenty novices with no prior endoscopic experience underwent repeated endoscopic simulator sessions using the part-task simulator. Simulator scores were collected; their inverse was averaged and fit to an exponential curve. The incremental improvement after each session was calculated. Plateau was defined as the session after which incremental improvement in simulator score model was less than 5%. Additionally, all participants filled out questionnaires regarding simulator experience after sessions 1, 5, 10, 15, and 20. A visual analog scale and NASA task load index were used to assess levels of comfort and demand. Twenty novices underwent 400 simulator sessions. Mean simulator scores at sessions 1, 5, 10, 15, and 20 were 78.5 ± 5.95, 176.5 ± 17.7, 275.55 ± 23.56, 347 ± 26.49, and 441.11 ± 38.14. The best fit exponential model was [time/score] = 26.1 × [session #] -0.615 ; r 2  = 0.99. This corresponded to an incremental improvement in score of 35% after the first session, 22% after the second, 16% after the third and so on. Incremental improvement dropped below 5% after the 12th session corresponding to the predicted score of 265. Simulator training was related to higher comfort maneuvering an endoscope and increased readiness for supervised clinical endoscopy, both plateauing between sessions 10 and 15. Mental demand, physical demand, and frustration levels decreased with increased simulator training. Preclinical training using an endoscopic part-task simulator appears to increase comfort level and decrease mental and physical demand associated with endoscopy. Based on a rigorous model, we recommend that novices complete a minimum of 12 training sessions and obtain a simulator score of at least 265 to be best prepared for clinical endoscopy.

We aimed to determine the incidence of esophageal strictures in corrosive ingestions and potential predictors of severe injury. This was a retrospective cohort study of corrosive ingestions from a toxicology unit (1987-2013) with telephone follow-up at least 1 y post-ingestion. Clinical data and investigations were obtained from a toxicology admission database. The primary outcome was esophageal stricture. Other outcomes included in-hospital mortality, endoscopy grade and early complications. There were 89 corrosive ingestions; median age, 31 y [1-87 y; 46 females], including 13 strong alkalis (pH>12), 8 strong acids (pH<2), 29 domestic bleaches, 30 other domestic products, 6 non-domestic products and three unknown. Three patients died in hospital within 24 h (phenol, sodium azide, HCl). Two developed strictures (both strong alkalis): one had complete esophageal destruction; another developed a stricture after 25 d (inpatient grade 2A endoscopy). 24 patients were asymptomatic and discharged without complication. 65 patients were symptomatic (4 catastrophic injuries). 61 reported sore mouth/throat (50), abdominal pain (21), chest pain (17), dysphagia (13); 28 had an abnormal oropharyngeal examination. 25/61 symptomatic patients underwent inpatient endoscopy: normal (3), grade 1 (5), grade 2 (15) and grade 3 (2). Of 88 patients, 12 died (3 inpatients, 9 unrelated), 28 couldn't be contacted and 48 were contacted after 1.7-24 y, including two with strictures. Five couldn't be interviewed (normal endoscopy (1), no dysphagia (3) and stroke (1). 4/41 interviewed reported dysphagia but no objective evidence of stricture. All inpatient deaths and severe complications were apparent within hours of ingestion, and occurred with highly corrosive substances. One delayed stricture occurred, not predicted by inpatient endoscopy. Copyright © 2016 Elsevier Inc. All rights reserved.

Chromoendoscopy in magnetically guided capsule endoscopy

PubMed Central

2013-01-01

Background Diagnosis of intestinal metaplasia and dysplasia via conventional endoscopy is characterized by low interobserver agreement and poor correlation with histopathologic findings. Chromoendoscopy significantly enhances the visibility of mucosa irregularities, like metaplasia and dysplasia mucosa. Magnetically guided capsule endoscopy (MGCE) offers an alternative technology for upper GI examination. We expect the difficulties of diagnosis of neoplasm in conventional endoscopy to transfer to MGCE. Thus, we aim to chart a path for the application of chromoendoscopy on MGCE via an ex-vivo animal study. Methods We propose a modified preparation protocol which adds a staining step to the existing MGCE preparation protocol. An optimal staining concentration is quantitatively determined for different stain types and pathologies. To that end 190 pig stomach tissue samples with and without lesion imitations were stained with different dye concentrations. Quantitative visual criteria are introduced to measure the quality of the staining with respect to mucosa and lesion visibility. Thusly determined optimal concentrations are tested in an ex-vivo pig stomach experiment under magnetic guidance of an endoscopic capsule with the modified protocol. Results We found that the proposed protocol modification does not impact the visibility in the stomach or steerability of the endoscopy capsule. An average optimal staining concentration for the proposed protocol was found at 0.4% for Methylene blue and Indigo carmine. The lesion visibility is improved using the previously obtained optimal dye concentration. Conclusions We conclude that chromoendoscopy may be applied in MGCE and improves mucosa and lesion visibility. Systematic evaluation provides important information on appropriate staining concentration. However, further animal and human in-vivo studies are necessary. PMID:23758801

Severe methemoglobinemia complicating topical benzocaine use during endoscopy in a toddler: a case report and review of the literature.

PubMed

Dahshan, Ahmed; Donovan, G Kevin

2006-04-01

Severe methemoglobinemia resulting from the use of topical benzocaine has been reported in adults as a rare complication. Here we report a case of severe acquired methemoglobinemia resulting from topical use of benzocaine spray during diagnostic upper gastrointestinal endoscopy in a 3-year-old boy with repeated episodes of hematemesis 3 weeks posttonsillectomy. He developed marked cyanosis and became increasingly agitated immediately after completion of his unremarkable endoscopic procedure, which was performed under intravenous sedation. He did not respond to maximum supplemental oxygen and had increased respiratory effort. His pulse oximetry dropped to 85%, but simultaneous arterial blood-gas analysis showed marked hypoxemia (Po2 = 29%) and severe methemoglobinemia (methemoglobin = 39%). His cyanosis and altered mental status promptly resolved after intravenous administration of methylene blue. In patients with methemoglobinemia, pulse oximetry tends to overestimate the actual oxygen saturation and is not entirely reliable. Posttonsillectomy bleeding is a rare but occasionally serious complication that could occur weeks after the surgery, although it more commonly occurs within the first few days. Physicians should remain aware of the possibility of its late onset. This case illustrates the severity of acquired methemoglobinemia that may result from even small doses of topical benzocaine and highlights the fact that prompt treatment of the disorder can be life saving. We question the rationale for routine use of topical anesthetic spray for sedated upper gastrointestinal endoscopy in children. By bringing the attention of pediatricians to this rare but serious complication, we hope that it will result in its improved recognition and possible prevention.

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

Helicobacter pylori (HP)-associated chronic gastritis can cause mucosal atrophy and intestinal metaplasia, both of which increase the risk of gastric cancer. The accurate diagnosis of HP infection during routine medical checks is important. We aimed to develop a convolutional neural network (CNN), which is a machine-learning algorithm similar to deep learning, capable of recognizing specific features of gastric endoscopy images. The goal behind developing such a system was to detect HP infection early, thus preventing gastric cancer.  For the development of the CNN, we used 179 upper gastrointestinal endoscopy images obtained from 139 patients (65 were HP-positive: ≥ 10 U/mL and 74 were HP-negative: < 3 U/mL on HP IgG antibody assessment). Of the 179 images, 149 were used as training images, and the remaining 30 (15 from HP-negative patients and 15 from HP-positive patients) were set aside to be used as test images. The 149 training images were subjected to data augmentation, which yielded 596 images. We used the CNN to create a learning tool that would recognize HP infection and assessed the decision accuracy of the CNN with the 30 test images by calculating the sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve (AUC).  The sensitivity and specificity of the CNN for the detection of HP infection were 86.7 % and 86.7 %, respectively, and the AUC was 0.956.  CNN-aided diagnosis of HP infection seems feasible and is expected to facilitate and improve diagnosis during health check-ups.

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.

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.

Abstract Rationale: Only a few cases of putative lung adenocarcinoma presenting as carcinoma of unknown primary site (CUP) with epidermal growth factor receptor (EGFR) mutation have been reported, and the efficacy of EGFR-tyrosine kinase inhibitors (TKIs) for these cases is unclear. Patient concerns and diagnoses: A 67-year-old man complained of paresis of the right lower extremity, dysarthria, and memory disturbance. Computed tomography and magnetic resonance imaging showed multiple brain tumors with brain edema and swelling of the left supraclavicular, mediastinal, and upper abdominal lymph nodes. Moreover, a metastatic duodenal tumor was detected via upper gastrointestinal endoscopy examination. The biopsy specimen of the lesion was examined and was diagnosed as adenocarcinoma with CK7 and TTF-1 positivity. Finally, the case was diagnosed as EGFR mutation-positive putative lung adenocarcinoma presenting as CUP. Interventions and outcomes: Oral erlotinib, an EGFR-TKI, was administered at 150 mg daily. Five weeks later, the brain lesions and several swollen lymph nodes showed marked improvement, and the symptoms of the patient also improved. Three months later, the duodenal lesion was undetected on upper gastrointestinal endoscopy. After an 8-month follow-up, the patient was well with no disease progression. Lessons: Putative lung adenocarcinoma presenting as CUP may have EGFR mutation, and EGFR-TKI therapy may be effective for such malignancy. PMID:29443782

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.

Cancers found in the resected branchial cleft cyst are rare clinically but usually impose substantive diagnostic and treatment challenges for clinicians. A 31-year-old man presented with a lateral neck mass that was suspected to be an inflammatory branchial cleft cyst. After excision, the pathologic specimen revealed a benign cystic appearance with a focus of undifferentiated carcinoma. Serologic tests for Epstein-Barr virus were negative. A positron emission tomography scan and upper aerodigestive tract endoscopies were negative for any other suspicious lesion. The patient underwent random biopsies of the nasopharynx, tongue base, and hypopharynx and bil tonsillectomy. Pathologic examination of the nasopharyngeal biopsies showed the presence of undifferentiated carcinoma. The cancerous part of the branchial cleft cyst and this nasopharyngeal specimen were positive for the latent membrane protein-1 and EBV-encoded RNAs of Epstein-Barr virus (EBV) and confirmed our diagnosis. This is the first report of a NPC metastasizing to a branchial cleft cyst. Molecular diagnostic techniques facilitate the definite diagnosis that enabled us to refine treatment plans and offered the patient a favorable outcome. Copyright © 2017 Elsevier B.V.

SUMMARY Aim of the present study was to investigate the prevalence of allergy in patients affected by both organic and/or functional vocal fold disorders. The secondary aim was to assess the correlation between sex and allergy in dysphonic patients. A retrospective chart review was performed on dysphonic patients. A total of 76 patients underwent fiberoptic endoscopy to assess the objective picture. Logistic regression analyses have been conducted to assess the association between sex and the outcome variables. The laryngoscopic examination revealed the presence of poor glottic closure in 32.9%, hyperkinesias in 11.8%, redness in 11.84%, polyps in 5.3%, oedema in 3.95%, vocal fold hypertrophy in 5.3%, nodules in 42.1%, cordectomy in 2.6%. Allergic rhinitis was present in 56.6%, milk intolerance in 13.2%, asthma in 9.2%, atopic dermatitis in 3.9%, drugs intolerance in 11.8%. A total of 76.32% patients presenting with dysphonia were allergic. A statistically significant association was found between female sex and presence of allergy. In conclusion, allergy testing should be performed routinely on female professional voice users. Mild respiratory disorders must be taken into serious consideration in female professional voice users, who may primarily complain of vocal dysfunction rather than upper and lower respiratory diseases.

Mucormycosis is a rare fungal infection of the mucorales order, which affects mostly immunocompromised patients. The association with emphysematous gastritis is rare and often fatal produced by gas -forming bacteria. We report the case of a trauma patient with type 1 diabetes mellitus, and diabetic ketoacidosis complicated with gastric mucormycosis associated with emphysematous gastritis. A male aged 32 who is involved in a car accident, who suffered head trauma, is admitted to the Intensive Care Unit, presenting diabetic ketoacidosis and upper gastrointestinal bleeding. An endoscopy was performed and an erosive esophagitis Class C, ischemia and gastric necrosis was found. A computed tomography scan showed emphysematous gastritis and gastric necrosis. He underwent total gastrectomy with a histopathology report of gastric mucormycosis. After the surgical procedure the patient died because of sepsis secondary to pulmonary mucormycosis Mucormycosis is a rare fungical disease which infrequently affects the gastrointestinal tract, being the stomach the most affected site. The mortality is high if the diagnosis is not done promptly and appropriate treatment is given. Suspecting its existence is necessary in patients with immunocompromised status to diagnose and provide timely treatment to increase survival, because of its high mortality. Copyright © 2015.

A 69-year-old man was admitted to the emergency department 3 hours after ingestion of a bleaching agent containing hypochlorous acid and sodium hydroxide in a suicide attempt. Enhanced chest computed tomography scans taken on admission indicated an edematous esophagus and air bubbles in the mediastinum. He underwent endotracheal intubation and mechanical ventilation until day 9 because of laryngeal edema. On day 10, his endoscopy indicated diffuse reddish mucosal hyperemia, erosions, and lacerated mucosal lesions in the esophagus that were indicative of grade 2b corrosive esophagitis. Treatment with a proton pump inhibitor was initiated, with which the condition of the esophagus improved, and on day 44, a slight stricture of the upper part of the esophagus was observed. He was discharged on day 64 without any complaints. The ingestion of sodium hypochlorite induces corrosive esophagitis and acute phase of gastritis. Ingestion of any corrosive agent is known as a risk factor for esophagus cancer in the long-term. In such cases with esophageal stricture, esophagectomy is recommended for preventing esophagus cancer. Considering the age of the patient, however, he did not undergo esophagectomy.

The goal of the study was to evaluate the prevalence and risk factors of esophageal motor disorders in systemic sclerosis. In 183 consecutive cases of scleroderma, as diagnosed by American College of Rheumatology criteria (1980). Patients' mean age was 40.6+/-13.3 years, the gender ratio was 0.13 and the average duration of disease was 6.8+/-7.5 years. A localized, cutaneous form was observed in 148 patients (81%) and a diffuse form in 35 (19%). All patients underwent upper gastrointestinal endoscopy and standard esophageal manometry. Esophageal symptoms and reflux esophagitis were found in 108 (59%) and 68 (37%) of patients, respectively. Esophageal motor disorders were present in 148 patients (81%), and were associated with a hypotensive lower esophageal sphincter in 114 (62%). The presence of these motor abnormalities was not related to age, gender, skin extension or duration of disease. Esophageal motor disorders were present in almost all patients with esophageal symptoms or esophagitis, and were also found in 48 (64%) of the asymptomatic patients. Esophageal motor disorders are frequently seen in scleroderma, especially in cases with clinical symptoms, but are not associated with a specific form of the disease.

To evaluate the prevalence and clinical features of Celiac disease among children with severe acute malnutrition (SAM). This prospective observational study was conducted in PBM Children Hospital, Bikaner from July 2012 through December 2013. All consecutively admitted children with SAM were recruited. All subjects were screened for Celiac disease by serological test for IgA-anti tissue Transglutaminase (IgA tTG) antibodies. All seropositive children underwent upper gastrointestinal endoscopy for small bowel biopsy for the confirmation. Clinical features of patients with and without celiac disease were compared. The sero-prevalence (IgA tTg positivity) of Celiac disease was found to be 15.38% while prevalence of biopsy confirmed Celiac disease was 14.42% among SAM children. Abdominal distension, diarrhea, anorexia, constipation, pain in abdomen, vitamin deficiencies, edema, clubbing and mouth ulcers were more common in patients of Celiac disease compared to patients without Celiac disease but the difference was statistically significant only for abdominal distension and pain abdomen. There is a high prevalence of Celiac disease in SAM. Screening for Celiac disease (especially in presence of pain abdomen and abdominal distension) should be an essential part of work-up in all children with SAM.

This prospective study was conducted over a 12-month period on patients who underwent upper digestive endoscopy for hematemesis in the medical intensive care unit (ICU) of the Tokoin University Hospital Center in Lomé, Togo. A total of 44 patients with a mean age of 44 years were included. The sex-ratio was 2.61. Risk factors included use of non-steroid anti-inflammatory (NSAI) in 16 patients (36.4%) and alcohol abuse in 13 (29.6%). At the time of admission to the ICU, 21 patients (47.7%) were in hemodynamic shock and 11 (25%) presented signs of portal hypertension. The underlying etiology was peptic ulcer in 18 cases (40.9%) including 13 cases of duodenal ulcer and 5 cases of stomach ulcer, rupture of esophageal varicosities in 8 (18.2%), gastric tumor in 6 (13.6%), Mallory Weiss syndrome in 5 (11.4%), gastritis in 4 (9,1%), and esophagitis in 3 (6.8%) due to peptic inflammation in 2 and mycotic infection in 1. The mortality rate was 45.5%. The main causes of hematemesis were peptic ulcer and rupture of esophageal varicosities. The death rate was high due to inadequate care facilities.

Does endoscopy diagnose early gastrointestinal cancer in patients with uncomplicated dyspepsia?

Background Recent guidelines from NICE have proposed that open access gastroscopy is largely limited to patients with “alarm” symptoms. Aims and methods This study reviewed the outcome of all our patients with verified oesophageal or gastric carcinoma who presented with uncomplicated dyspepsia to see if endoscopic investigation is warranted in this group. All patients with histologically verified upper gastrointestinal (GI) cancers who presented over a period from 1998 to 2002 were identified. Their presenting symptoms, treatment, and outcome were analysed. Results 228 upper GI cancers (119 oesophageal, 109 gastric; mean age 72 years (29–99 years); 130 male, 82 female) were identified in 11 145 endoscopies performed. Only 14 patients (6.2%) presented without alarm symptoms; three patients were under 55 years of age and all had gastric carcinoma—one of these had chronic diarrhoea only. Eleven had dyspepsia or reflux symptoms only, and two were under surveillance for Barrett's oesophagus. Only five patients had a curative surgical resection and are still alive two—six years from diagnosis. A sixth patient had a curative operation but died of a cerebrovascular accident one year later. The remaining eight patients unfortunately had either metastatic disease or comorbidity, which precluded surgery. All of these died within two years of diagnosis, mean survival 10 months. Conclusion Only five patients with dyspepsia and no alarm symptoms had resectable upper GI malignancies over a four year period. Limiting open access gastroscopy to those with alarm features only would “miss” a small number of patients who have curable upper GI malignancy. PMID:16397081

Acute upper gastrointestinal bleeding, previously often a surgical problem, is now the most common gastroenterological emergency. To evaluate the current situation in terms of mortality and need of surgery. Retrospective non-randomised clinical study performed between 1st January-31st December 2011, at "Professor Dr. Octavian Fodor" Regional Institute of Gastroenterology and Hepatology in Cluj Napoca. 757 patients with upper gastrointestinal bleeding were endoscopically examined within 24 hours from presentation in the emergency unit. Data were collected from admission charts and Hospital Manager programme. Statistical analysis was performed with GraphPad 2004, using the following tests: chi square, Spearman, Kruskall-Wallis, Mann-Whitney, area under receiver operating curve. Non-variceal etiology was predominant, the main cause was bleeding being peptic ulcer. In hospital global mortality was of 10.43%, global rebleeding rate was 12.02%, surgery was performed in 7.66% of patients. Urgent haemostatic surgery was needed in 3.68% of patients with nonvariceal bleeding. The need for surgery correlated with the postendoscopic Rockall score (p=0.0425). In peptic ulcer, the need for surgery was not influenced by time to endoscopy or type of treatment (p=0.1452). Weekend (p=0.996) or night (p=0.5414) admission were not correlated with a higher need for surgery. Over the last decade, the need for urgent surgery in upper gastrointestinal bleeding has decreased by half, but mortality has remained unchanged. Celsius.

Re-bleeding after initial hemostasis in peptic ulcer bleeding can be life threatening. Identification of factors associated with re-bleeding is important. The aims of this study were to determine incidence of rebleeding in patients with high risk peptic ulcer bleeding and to evaluate factors associated with rebleeding. Among patients diagnosed as upper gastrointestinal hemorrhage at seven hospitals in Daegu-Gyeongbuk, and one hospital in Gyeongnam, South Korea, from Feb 2011 to Dec 2013, 699 patients diagnosed as high risk peptic ulcer bleeding with Forrest classification above llb were included. The data were obtained in a prospective manner. Among 699 patients, re-bleeding occurred in 64 (9.2 %) patients. Second look endoscopy was significantly more performed in the non-rebleeding group than the rebleeding group (81.8 vs 62.5 %, p < 0.001). In multivariate analysis, use of non-steroidal anti-inflammatory agents, larger transfusion volume (≥5 units), and non-performance of second look endoscopy were found as risk factors for rebleeding in high risk peptic ulcer bleeding. In our study, rebleeding was observed in 9.2 % of patients with high risk peptic ulcer bleeding. Performance of second look endoscopy seems to lower the risk of rebleeding in high risk peptic ulcer bleeding patients and caution should be paid to patients receiving high volume transfusion and on medication with NSAIDs.

Capsule endoscopy: The road ahead

2016-01-01

Since its introduction into clinical practice 15 years ago, capsule endoscopy (CE) has become the first-line investigation procedure in some small bowel pathologies, and more recently, dedicated esophageal and colon CE have expanded the fields of application to include the upper and lower gastrointestinal disorders. During this time, CE has become increasingly popular among gastroenterologists, with more than 2 million capsule examinations performed worldwide, and nearly 3000 PubMed-listed studies on its different aspects published. This huge interest in CE may be explained by its non-invasive nature, patient comfort, safety, and access to anatomical regions unattainable via conventional endoscopy. However, CE has several limitations which impede its wider clinical applications, including the lack of therapeutic capabilities, inability to obtain biopsies and control its locomotion. Several research groups are currently working to overcome these limitations, while novel devices able to control capsule movement, obtain high quality images, insufflate the gut lumen, perform chromoendoscopy, biopsy of suspect lesions, or even deliver targeted drugs directly to specific sites are under development. Overlooking current limitations, especially as some of them have already been successfully surmounted, and based on the tremendous progress in technology, it is expected that, by the end of next 15 years, CE able to perform both diagnostic and therapeutic procedures will remain the major form of digestive endoscopy. This review summarizes the literature that prognosticates about the future developments of CE. PMID:26755883

Diagnosis and management of upper gastrointestinal bleeding in children.

PubMed

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.

High-resolution endoscopy (HRE) may improve the detection of early neoplasia in Barrett's esophagus. Indigo carmine chromoendoscopy (ICC) and narrow-band imaging (NBI) may be useful techniques to complement HRE. The aim of this study was to compare HRE-ICC with HRE-NBI for the detection of high-grade dysplasia or early cancer (HGD/EC) in patients with Barrett's esophagus. Twenty-eight patients with Barrett's esophagus underwent HRE-ICC and HRE-NBI (separated by 6 - 8 weeks) in a randomized sequence. The two procedures were performed by two different endoscopists, who were blinded to the findings of the other examination. Targeted biopsies were taken from all detected lesions, followed by four-quadrant biopsies at 2-cm intervals. Biopsy evaluation was supervised by a single expert pathologist, who was blinded to the imaging technique used. Fourteen patients were diagnosed with HGD/EC. The sensitivity for HGD/EC was 93 % and 86 % for HRE-ICC and HRE-NBI, respectively. Targeted biopsies had a sensitivity of 79 % with HRE alone. HGD was diagnosed from random biopsies alone in only one patient. ICC and NBI detected a limited number of additional lesions occult to HRE, but these lesions did not alter the sensitivity for identifying patients with HGD/EC. In most patients with high-grade dysplasia or early cancer in Barrett's esophagus, subtle lesions can be identified with high-resolution endoscopy. Indigo carmine chromoendoscopy and narrow-band imaging are comparable as adjuncts to high-resolution endoscopy.

In 1971, Micheal Hogan introduced the Lateral Port Control Pharyngeal Flap (LPCPF) which obtained good results with elimination of VPI. However, there was a high incidence of hyponasality and OSA. We hypothesized that preoperative assessment with videofluoroscopy and nasal endoscopy would enable modification and customization of the LPCPF and result in improvement in the result in both hyponasality and obstructive apnea while still maintaining results in VPI. Thirty consecutive patients underwent customized LPCPF. All patients had preoperative diagnosis of VPI resulting from cleft palate. Patient underwent either videofluoroscopy or nasal endoscopy prior to the planning of surgery. Based on preoperative velar and pharyngeal movement, patients were assigned to wide, medium, or narrow port designs. Patients with significant lateral motion were given wide ports while patients with minimal movement were given narrow ports. There was a 96.66% success rate in the treatment of VPI with one patient with persistent VPI (3.33%). Six patients had mild hyponasality (20 %). Two patients had initial OSA (6.67%), one of which had OSA which lasted longer than six months (3.33%). The modifications of the original flap description have allowed for success in treatment of VPI along with an acceptably low rate of hyponasality and OSA. PMID:23365734

Postoperative leak is a serious complication of bariatric surgery and often results in significant morbidity and mortality. Stent placement is a less invasive alternative to surgery for the treatment of bariatric surgical leak. We evaluated the efficacy and complications of covered self-expandable metal stents (SEMS) in the treatment of post-bariatric surgical leak. We retrospectively reviewed patients who underwent stent placement for leak after bariatric surgery. Leak was diagnosed by upper gastrointestinal series or was visualized during the endoscopy. We examined the timing of stent placement, size of the leak, stent migration and its complications, total stent treatment duration, and treatment outcome. Between January 2011 and April 2015, seven patients underwent covered SEMS placement for leak after bariatric surgery, including laparoscopic sleeve gastrectomy (LSG) (n = 5) and laparoscopic loop duodenojejunal bypass with sleeve gastrectomy (LDJB-SG) (n = 2). A stent was placed in one patient for infection control and bridging to revisional surgery. Among the other six patients, one patient who received stent placement one year after leak diagnosis failed to achieve leak closure, and five patients with early stent placement achieved leak closure. Three patients with small leak achieved leak closure more quickly. Stent migration was found in six patients, and associated ulcers occurred in five patients. We conclude that stenting is effective in the management of staple-line leaks following LSG and LDJB-SG. Stent migration and associated ulcers are common after stent placement. Early stent removal can be achieved in patients with small leaks. Copyright © 2017. Published by Elsevier Taiwan.

To investigate gastrointestinal complications associated with non-steroidal anti-inflammatory drug (NSAIDs) use in children. A retrospective, multicenter study was conducted between January 2005 and January 2013, with the participation of 8 Italian pediatric gastroenterology centers. We collected all the cases of patients who refer to emergency room for suspected gastrointestinal bleeding following NSAIDs consumption, and underwent endoscopic evaluation. Previous medical history, associated risk factors, symptoms and signs at presentation, diagnostic procedures, severity of bleeding and management of gastrointestinal bleeding were collected. In addition, data regarding type of drug used, indication, dose, duration of treatment and prescriber (physician or self-medication) were examined. Fifty-one patients, including 34 males, were enrolled (median age: 7.8 years). Ibuprofen was the most used NSAID [35/51 patients (68.6%)]. Pain was the most frequent indication for NSAIDs use [29/51 patients (56.9%)]. Seven patients had positive family history of Helicobacter pylori (H. pylori) infection or peptic ulcer, and 12 had associated comorbidities. Twenty-four (47%) out of 51 patients used medication inappropriately. Hematemesis was the most frequent symptom (33.3%). Upper gastrointestinal endoscopy revealed gastric lesions in 32/51 (62%) patients, duodenal lesions in 17 (33%) and esophageal lesions in 8 (15%). In 10/51 (19.6%) patients, a diagnosis of H. pylori gastritis was made. Forty-eight (94%) patients underwent medical therapy, with spontaneous bleeding resolution, while in 3/51 (6%) patients, an endoscopic hemostasis was needed. The data collected in this study confirms that adverse events with the involvement of the gastrointestinal tract secondary to NSAID use are also common in children.

The value of using heparin as a pharmacologic intervention to induce a positive scintiscan was studied in a patient with chronic occult gastrointestinal bleeding. When all standard diagnostic tests (upper and lower gastrointestinal series, upper and lower endoscopy, and conventional noninterventional Tc-99m RBC imaging) fail to detect and localize gastrointestinal bleeding in a patient who has definite clinical evidence (guaiac positive stool and dropping hemoglobin, hematocrit) of chronic occult gastrointestinal oozing, heparin may be used (with proper precaution) as a last resort to aid in the scintigraphic detection and localization of chronic occult gastrointestinal bleeding.

[Upper gastrointestinal bleeding: usefulness of prognostic scores].

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.

Evaluation and treatment of iron deficiency anemia: a gastroenterological perspective.

A substantial volume of the consultations requested of gastroenterologists are directed towards the evaluation of anemia. Since iron deficiency anemia often arises from bleeding gastrointestinal lesions, many of which are malignant, establishment of a firm diagnosis usually obligates an endoscopic evaluation. Although the laboratory tests used to make the diagnosis have not changed in many decades, their interpretation has, and this is possibly due to the availability of extensive testing in key populations. We provide data supporting the use of the serum ferritin as the sole useful measure of iron stores, setting the lower limit at 100 microg/l for some populations in order to increase the sensitivity of the test. Trends of the commonly obtained red cell indices, mean corpuscular volume, and the red cell distribution width can provide valuable diagnostic information. Once the diagnosis is established, upper and lower gastrointestinal endoscopy is usually indicated. Nevertheless, in many cases a gastrointestinal source is not found after routine evaluation. Additional studies, including repeat upper and lower endoscopy and often investigation of the small intestine may thus be required. Although oral iron is inexpensive and usually effective, there are many gastrointestinal conditions that warrant treatment of iron deficiency with intravenous iron.

The aim of this study is to report our six-year experience with portal-endocrine and gastric-exocrine drainage technique of pancreatic transplantation, which was first developed and implemented at our center in 2007. In this study, the outcomes of all patients at our center who had pancreas transplantation with portal-endocrine and gastric-exocrine drainage technique were evaluated. From October 2007 to November 2013, 38 patients had pancreas transplantation with this technique - 31 simultaneous kidney pancreas and seven pancreas alone. Median duration of follow-up was 3.8 years. One-, three-, and five-year patient and graft survival rates were 94%, 87%, 70% and 83%, 65%, 49%, respectively. For pancreas allograft dysfunction evaluation, 51 upper endoscopies were performed in 14 patients; donor duodenal biopsies were successfully obtained in 45 (88%). We detected nine episodes of acute rejection (eight patients) and seven episodes of cytomegalovirus (CMV) duodenitis (six patients). No patient developed any complication due to upper endoscopy. Portal-endocrine and gastric-exocrine drainage technique of pancreas transplantation provides lifelong easy access to the transplanted duodenum for evaluation of pancreatic allograft dysfunction.

Upper Gastrointestinal Conditions: Nonmalignant Conditions of the Esophagus.

Estores, David S; Chang, Ku-Lang

Eosinophilic esophagitis (EE) is an allergic disorder of the esophagus. This diagnosis requires the presence of specific symptoms and a significantly elevated number of eosinophils in the esophageal lining as determined by endoscopic biopsies. Symptoms tend to be nonspecific among patients younger than 15 years. Among adults, dysphagia is the most common symptom. Comanagement with a gastroenterology subspecialist is essential, particularly for EE patients with a stricture. EE is commonly misdiagnosed as gastroesophageal reflux disease (GERD). The diagnosis of GERD is established by symptom response (eg, postprandial heartburn, regurgitation) to acid suppression, such as administration of a once-daily proton pump inhibitor. Red flag signs and symptoms for esophageal cancer include dysphagia, weight loss, and unexplained anemia. Risk factors include tobacco use, obesity, a long history of heartburn, and a family history of esophageal cancer. Most experts agree that the presence of risk factor(s) signals the need for screening with an upper endoscopy. An abnormal or pathologic pH study result for a patient with negative endoscopy results indicates the presence of nonerosive reflux disease.

AIM: To examine the available evidence on safety, competency and cost-effectiveness of nursing staff providing gastrointestinal (GI) endoscopy services. METHODS: The literature was searched for publications reporting nurse endoscopy using several databases and specific search terms. Studies were screened against eligibility criteria and for relevance. Initial searches yielded 74 eligible and relevant articles; 26 of these studies were primary research articles using original datasets relating to the ability of non-physician endoscopists. These publications included a total of 28883 procedures performed by non-physician endoscopists. RESULTS: The number of publications in the field of non-specialist gastrointestinal endoscopy reached a peak between 1999 and 2001 and has decreased thereafter. 17/26 studies related to flexible sigmoidoscopies, 5 to upper GI endoscopy and 6 to colonoscopy. All studies were from metropolitan centres with nurses working under strict supervision and guidance by specialist gastroenterologists. Geographic distribution of publications showed the majority of research was conducted in the United States (43%), the United Kingdom (39%) and the Netherlands (7%). Most studies conclude that after appropriate training nurse endoscopists safely perform procedures. However, in relation to endoscopic competency, safety or patient satisfaction, all studies had major methodological limitations. Patients were often not randomized (21/26 studies) and not appropriately controlled. In relation to cost-efficiency, nurse endoscopists were less cost-effective per procedure at year 1 when compared to services provided by physicians, due largely to the increased need for subsequent endoscopies, specialist follow-up and primary care consultations. CONCLUSION: Contrary to general beliefs, endoscopic services provided by nurse endoscopists are not more cost effective compared to standard service models and evidence suggests the opposite. Overall significant shortcomings and biases limit the validity and generalizability of studies that have explored safety and quality of services delivered by non-medical endoscopists. PMID:25945022

To evaluate the adequacy of paediatric informed consent and its augmentation by a supplemental computer-based module in paediatric endoscopy. The Consent-20 instrument was developed and piloted on 47 subjects. Subsequently, parents of 101 children undergoing first-time, diagnostic upper endoscopy performed under moderate IV sedation were prospectively and consecutively, blinded, randomised and enrolled into two groups that received either standard form-based informed consent or standard form-based informed consent plus a commercial (Emmi Solutions, Inc, Chicago, Il), sixth grade level, interactive learning module (electronic assisted consent). Anonymously and electronically, the subjects' anxiety (State Trait Anxiety Inventory), satisfaction (Modified Group Health Association of America), number of questions asked, and attainment of informed consent were assessed (Consent-20). Statistics were calculated using t test, paired t test, and Mann Whitney tests. The ability to achieve informed consent, as measured by the new instrument, was 10% in the control form-based consent group and 33% in the electronic assisted consent group (p<0.0001). Electronically assisting form-based informed consent did not alter secondary outcome measures of subject satisfaction, anxiety or number of questions asked in a paediatric endoscopy unit. This study demonstrates the limitations of form-based informed consent methods for paediatric endoscopy. It also shows that even when necessary information was repeated electronically in a comprehensive and standardised video, informed consent as measured by our instrument was incompletely achieved. The supplemental information did, however, significantly improve understanding in a manner that did not negatively impact workflow, subject anxiety or subject satisfaction. Additional study of informed consent is required.

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.

To distinguish upper from lower gastrointestinal (GI) bleeding. Patient records between April 2011 and March 2014 were analyzed retrospectively (3296 upper endoscopy, and 1520 colonoscopy). Seventy-six patients had upper GI bleeding (Upper group) and 65 had lower GI bleeding (Lower group). Variables were compared between the groups using one-way analysis of variance. Logistic regression was performed to identify variables significantly associated with the diagnosis of upper vs lower GI bleeding. Receiver-operator characteristic (ROC) analysis was performed to determine the threshold value that could distinguish upper from lower GI bleeding. Hemoglobin (P = 0.023), total protein (P = 0.0002), and lactate dehydrogenase (P = 0.009) were significantly lower in the Upper group than in the Lower group. Blood urea nitrogen (BUN) was higher in the Upper group than in the Lower group (P = 0.0065). Logistic regression analysis revealed that BUN was most strongly associated with the diagnosis of upper vs lower GI bleeding. ROC analysis revealed a threshold BUN value of 21.0 mg/dL, with a specificity of 93.0%. The threshold BUN value for distinguishing upper from lower GI bleeding was 21.0 mg/dL.

Gastric lipoma presenting as a giant bulging mass in an oligosymptomatic patient: a case report

PubMed Central

2012-01-01

Introduction Lipomas of the gastrointestinal tract are a rare condition. Only 5% are of gastric origin, and this corresponds to 2% to 3% of all benign tumors of the stomach and less than 1% of all gastric neoplasms. It is our purpose to report an unusual presentation of a giant gastric lipoma in an oligosymptomatic patient and highlight the importance of discussing differential diagnosis in this situation. A review of the literature has shown that this is one of the largest gastric lipomas described. Case presentation We describe a rare case of a benign gastric tumor with uncommon features in a 63-year-old Caucasian woman. She was admitted with abdominal discomfort, nausea, and upper abdominal fullness after eating. The lesion was suspicious of malignancy because of its dimension and central contrast enhancement on computed tomography. Conventional upper digestive endoscopy revealed a large bulging mass in the gastric posterior wall and three ulcerated areas. In this procedure, a technical limitation due to the location of the mass in the submucosa prevented an adequate biopsy from being obtained. The fragments obtained from the ulcers revealed nothing but necrotic mucosa. Our patient underwent a subtotal gastrectomy and D1 lymphadenectomy with a Roux-en-Y reconstruction. Macroscopic findings revealed a 12 × 8 × 6cm mass with a volume of 576cm3, and the histological pattern demonstrated well-differentiated mature adipose tissue surrounded by a fibrous capsule, confirming the diagnosis of gastric submucosal lipoma. Conclusions Gastric lipoma is a rare benign disease that eventually simulates a malignant tumor. PMID:23006791

Management of a postbulbar duodenal ulcer and stricture causing gastric outlet obstruction: A case report.

Mirande, Maxwell D; Mirande, Raul A

Peptic ulcer disease has significantly decreased over the past several decades making the need for definitive surgical intervention an infrequent occurrence. A 44-year-old Caucasian female was sent to the emergency department by her primary care physician for right upper quadrant abdominal pain which had been intermittent for the past two months but acutely worsened over the last five days. During this time, she was unable to tolerate oral intake with intractable nausea and vomiting. Upper GI endoscopy revealed a tight stricture in the second part of the duodenum and antral biopsy was Helicobacter pylori negative. Patient underwent two rounds of balloon dilation with short lived symptomatic relief. An open pylorus-preserving duodenal stricturoplasty using a Heineke-Mikulicz technique was then performed. The operation was successful and the patient has had no reoccurrence of her symptoms. Gastric outlet obstruction is an uncommon complication of peptic ulcer disease in respect to chronic nonsteroidal anti-inflammatory drug use. The unique location of the patient's stricture and her desire to minimize post-operative GI alterations demanded a review of surgical options and identified the benefits of maintaining the patient's original anatomy versus choosing an extra-anatomic approach. This case presented a unique challenge and demonstrated the need for definitive surgical interventions in the treatment of peptic ulcer induced gastric outlet obstruction. This case adds support for the direct anatomic treatment of duodenal strictures when conservative measures fail and perhaps promotes further development of laparoscopic management of gastric outlet obstruction in the future.

Recent guidelines recommend that all cirrhotics undergo screening upper endoscopy to identify those patients at risk for bleeding from varices. However, this practice may not be cost effective as large esophageal varices are seen only in 9-36% of these patients. The aim of this study was to determine whether clinical variables were predictive of the presence of large esophageal varices. This is a retrospective analysis of cirrhotics who had a screening upper endoscopy during an evaluation for liver transplantation at three different centers and who had not previously bled from varices. A multivariate model was derived on the combined cohort using logistic regression. Three hundred forty-six patients were eligible for the study. The prevalence of large esophageal varices was 20%. On multivariate analysis, splenomegaly detected by computed tomographic scan (odds ratio: 4.3; 95% confidence interval: 1.6-11.5) or by physical examination (odds ratio: 2.0; 95% confidence interval: 1.1-3.8), and low platelet count were independent predictors of large esophageal varices. On the basis of these variables, cirrhotics were stratified into high- and low-risk groups for the presence of large esophageal varices. Patients with a platelet count of > or = 88,000/mm3 (median value) and no splenomegaly by physical examination had a risk of large esophageal varices of 7.2%. Those with splenomegaly or platelet count < 88,000/mm3 had a risk of large esophageal varices of 28% (p < 0.0001). Our data show that clinical predictors could be used to stratify cirrhotic patients for the risk of large esophageal varices and such stratification could be used to improve the cost effectiveness of screening endoscopy.

Diagnosis of eosinophilic esophagitis (EoE) and determination of response to therapy is based on histological assessment of the esophagus, which requires upper endoscopy. In children, in whom a dietary approach is commonly used, multiple endoscopies are needed, because foods are eliminated and then gradually reintroduced. Ideally, noninvasive methods could supplement or replace upper endoscopy to facilitate management. Fractionated exhaled nitric oxide (FeNO) has been proposed as a useful measure for monitoring disease activity in studies of patients with eosinophil-predominant asthma and in other atopic disorders. Thus, we evaluated whether FeNO levels could be a useful biomarker to assess the response to therapy in EoE patients. This study was designed to determine whether there is a change in FeNO levels during treatment with topical corticosteroids and whether changes correlated with clinical response. This was a prospective, multicenter study that enrolled nonasthmatic patients with established EoE. FeNO levels and symptom scores were measured at baseline, biweekly during 6-week swallowed fluticasone treatment, and 4 weeks posttreatment. Twelve patients completed the trial. We found a statistically significant difference between median pre- and posttreatment FeNO levels [20.3 ppb (16.0–29.0 ppb) vs 17.6 ppb (11.7–27.3 ppb), p=0.009]. However, neither the pretreatment FeNO level, a change of FeNO level after 2 weeks of treatment, nor the FeNO level at the end of treatment confidently predicted a clinical or histological response. Although our findings suggest nitric oxide possibly has a physiological role in EoE, our observations do not support a role of FeNo determination for management of EoE. PMID:23394511

Not all patients with upper gastrointestinal bleeding (UGIB) require emergency endoscopy. Lactate clearance has been suggested as a parameter for predicting patient outcomes in various critical care settings. This study investigates whether lactate clearance can predict active bleeding in critically ill patients with UGIB. This single-center, retrospective, observational study included critically ill patients with UGIB who met all of the following criteria: admission to the emergency department (ED) from April 2011 to August 2014; had blood samples for lactate evaluation at least twice during the ED stay; and had emergency endoscopy within 6 h of ED presentation. The main outcome was active bleeding detected with emergency endoscopy. Classification and regression tree (CART) analyses were performed using variables associated with active bleeding to derive a prediction rule for active bleeding in critically ill UGIB patients. A total of 154 patients with UGIB were analyzed, and 31.2 % (48/154) had active bleeding. In the univariate analysis, lactate clearance was significantly lower in patients with active bleeding than in those without active bleeding (13 vs. 29 %, P < 0.001). Using the CART analysis, a prediction rule for active bleeding is derived, and includes three variables: lactate clearance; platelet count; and systolic blood pressure at ED presentation. The rule has 97.9 % (95 % CI 90.2-99.6 %) sensitivity with 32.1 % (28.6-32.9 %) specificity. Lactate clearance may be associated with active bleeding in critically ill patients with UGIB, and may be clinically useful as a component of a prediction rule for active bleeding.

To (1) assess upper airway function by videoendoscopy in horses performing poorly after laryngoplasty and (2) establish whether dynamic collapse of the left arytenoid can be predicted by the degree of resting postsurgical abduction. Case series. Horses that had left laryngoplasty (n=45). Medical records (June 1993-December 2007) of horses evaluated for abnormal respiratory noise and/or poor performance after laryngoplasty were reviewed. Horses with video recordings of resting and exercising upper airway endoscopy were included and postsurgical abduction categorized. Horses with immediate postoperative endoscopy recordings were also evaluated and postsurgical abduction categorized. Relationships between resting postsurgical abduction and historical information with exercising endoscopic findings were examined. Dynamic collapse of the left arytenoid cartilage was probable in horses with no postsurgical abduction and could not be predicted in horses with grade 3 or 4 postsurgical abduction. Respiratory noise was associated with upper airway obstruction but was not specific for arytenoid collapse. Most horses with a left vocal fold had billowing of the fold during exercise. Other forms of dynamic collapse involved the right vocal fold, aryepiglottic folds, corniculate process of left arytenoid cartilage, dorsal displacement of soft palate, and pharyngeal collapse. Complex obstructions were observed in most examinations and in all horses with exercising collapse of the left arytenoid cartilage. There was no relationship between exercising collapse of the left arytenoid cartilage and grade 3 or 4 postsurgical abduction but was likely in horses with no abduction. © Copyright 2010 by The American College of Veterinary Surgeons.

Assessing the likelihood of a variceal versus nonvariceal source of upper gastrointestinal bleeding (UGIB) guides therapy, but can be difficult to determine on clinical grounds. The objective of this study was to determine if there are easily ascertainable clinical and laboratory findings that can identify a patient as low risk for a variceal source of hemorrhage. This was a retrospective cohort study of adult ED patients with UGIB between January 2008 and December 2014 who had upper endoscopy performed during hospitalization. Clinical and laboratory data were abstracted from the medical record. The source of the UGIB was defined as variceal or nonvariceal based on endoscopic reports. Binary recursive partitioning was utilized to create a clinical decision rule. The rule was internally validated and test characteristics were calculated with 1,000 bootstrap replications. A total of 719 patients were identified; mean age was 55 years and 61% were male. There were 71 (10%) patients with a variceal UGIB identified on endoscopy. Binary recursive partitioning yielded a two-step decision rule (platelet count > 200 × 10 9 /L and an international normalized ratio [INR] < 1.3), which identified patients who were low risk for a variceal source of hemorrhage. For the bootstrapped samples, the rule performed with 97% sensitivity (95% confidence interval [CI] = 91%-100%) and 49% specificity (95% CI = 44%-53%). Although this derivation study must be externally validated before widespread use, patients presenting to the ED with an acute UGIB with platelet count of >200 × 10 9 /L and an INR of <1.3 may be at very low risk for a variceal source of their upper gastrointestinal hemorrhage. © 2017 by the Society for Academic Emergency Medicine.

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.

Background and aims: The indication for endoscopy to investigate anemia of causes other than iron deficiency is not clear. Increasing numbers of endoscopic procedures for anemia raises concerns about costs to the health system, waiting times, and patient safety. The primary aim of this study was to determine the diagnostic yield of endoscopy in patients referred to undergo investigation for anemia. Secondary aims were to identify additional factors enabling the risk stratification of those likely to benefit from endoscopic investigation, and to undertake a cost analysis of performing endoscopy in this group of patients. Methods: We performed a retrospective review of endoscopy referrals for the investigation of anemia over a 12-month period at a single center. The patients were divided into three groups: those who had true iron deficiency anemia (IDA), tissue iron deficiency without anemia (TIDWA), or anemia of other cause (AOC). Outcome measures included finding a lesion responsible for the anemia and a significant change of management as a result of endoscopy. A costing analysis was performed with an activity-based costing method. Results: We identified 283 patients who underwent endoscopy to investigate anemia. A likely cause of anemia was found in 31 of 150 patients with IDA (21 %) and 0 patients in the other categories (P < 0.001). A change of management was observed in 35 patients with IDA (23 %), 1 of 14 patients with TIDWA (7.14 %), and 8 of 119 patients with AOC (6.7 %) (P < 0.001). The cost of a single colonoscopy or gastroscopy was approximated to be $ 2209. Conclusions: Endoscopic investigation for non-IDA comes at a significant cost to our institution, equating to a minimum of $ 293 797 per annum in extra costs, and does not result in a change of management in the majority of patients. No additional factors could be established to identify patients who might be more likely to benefit from endoscopic investigation. The endoscopic investigation of non-IDA should be minimized.

Background/Aim: There are currently no data on the relative retention rates of the Instinct clip, Resolution clip, and QuickClip2Long. Also, it is unknown whether retention rate differs when clips are applied to ulcerated rather than normal mucosa. The aim of this study is to compare the retention rates of three commonly used endoscopic clips. Materials and Methods: Six pigs underwent upper endoscopy with placement of one of each of the three types of clips on normal mucosa in the gastric body. Three mucosal resections were also performed to create “ulcers”. Each ulcer was closed with placement of one of the three different clips. Repeat endoscopy was performed weekly for up to 4 weeks. Results: Only the Instinct and Resolution clips remained attached for the duration of the study (4 weeks). At each time point, a greater proportion of Instinct clips were retained on normal mucosa, followed by Resolution clips. QuickClip2Long had the lowest retention rate on normal mucosa. Similar retention rates of Instinct clips and Resolution clips were seen on simulated ulcers, although both were superior to QuickClip2Long. However, the difference did not reach statistical significance. All QuickClip2Long clips were dislodged at 4 weeks in both the groups. Conclusions: The Resolution and Instinct clips have comparable retention rates and both appeared to be better than the QuickClip2Long on normal mucosa-simulated ulcers; however this did not reach statistical significance. Both the Resolution clip and the Instinct clip may be preferred in clinical situations when long-term clip attachment is required, including marking of tumors for radiotherapy and anchoring feeding tubes or stents. Either of the currently available clips may be suitable for closure of iatrogenic mucosal defects without features of chronicity. PMID:25434317

It still remains an open debate whether Helicobacter pylori eradication is beneficial or not for the improvement of symptoms in functional dyspepsia. Differences in geographic distribution, the worldwide H. pylori genetic variability and the fact that the outcome of infection is strongly related to the virulence of the infecting strain are factors that might be driving ongoing controversies. To study the correlation between gastric histology and H. pylori serology status in patients with dyspepsia. This is a cross-sectional study where 40 consecutive dyspeptic patients (28 women and 12 men, mean age 48.5 years) with endoscopically normal stomachs were selected from the endoscopy unit at a university hospital in Recife, PE, Northeast of Brazil, between March 1998 and July 1999. Patients underwent gastric mucosal biopsy and serological tests (anti-Hp and anti-CagA antibodies). Gastric biopsies were examined using H-E and Giemsa stains and gastritis was classified and graded (mild, moderate or severe) according to 'the updated Sydney System-Houston, 1994'. Among 40 patients with dyspepsia the gastric histology revealed that about (1/4) had moderate (25%) or severe (2.5%) gastritis. This subgroup of patients also had a greater positive frequency of anti-Hp (100% vs 41%; P = 0.0005) and anti-CagA (91% vs 58%; P = 0.09) antibodies when compared with those with normal histology (27.5%) or mild gastritis (45%). Since upper gastrointestinal endoscopy is part of the functional dyspepsia investigation and serology for anti-CagA antibody is not available in daily clinical practice, by biopsying gastric mucosa we would only be able to selectively apply H. pylori eradication therapy for those with histology that best correlate with virulent infecting strains (moderate or severe gastritis)--around (1/4) of our study patients with dyspepsia.

Background and study aims  Unsedated transnasal endoscopy (uTNE) has become accepted as a safe and tolerable method for upper gastrointestinal tact examinations. Epistaxis is 1 of the major complications of TNE, though its risk factors have not been elucidated. Generally, patients administered an anticoagulant or antiplatelet drug are considered to have an increased risk of epistaxis during TNE. Here, we investigated risk factors of epistaxis in patients undergoing uTNE, with focus on those who received antithrombotic agents. Patients and methods  We enrolled 6860 patients (average age 55.6 ± 12.97 years; 3405 males, 3455 females) who underwent uTNE and received the same preparations for the procedure. Epistaxis was evaluated using endoscopic images obtained while withdrawing the scope through the nostril. We also noted current use of medications including anticoagulant or antiplatelet agents prior to the endoscopic examination. Results  Epistaxis occurred in 3.6 % of the enrolled patients (245/6860), and that rate was significantly higher in younger patients (average age 49.31 ± 11.8 years for epistaxis group vs. 55.83 ± 13.0 years for no epistaxis group, P  < 0.01) as well as females (4.78 % vs. 2.35 %, P  < 0.01). The odds ratio for occurrence of epistaxis was 2.31 (95 %CI: 1.746 – 3.167) in the younger patients and 2.02 (95 % CI: 1.542 – 2.659) in females. In contrast, there was no significant difference for rate of epistaxis between patients with and without treatment with an antithrombotic agent (3.0 % vs. 3.6 %). Conclusions  The rate of epistaxis was higher in younger and female patients. Importantly, that rate was not significantly increased in patients who were administered an antithrombotic agent.

To determine the prognostic risk factors of gastrointestinal bleeding in emergency department cases. The trial was a retrospective single-center study involving 600 patients over 18-years-old and carried out with approval by the Institutional Ethics Committee. Patient data included demographic characteristics, symptoms at admission, past medical history, vital signs, laboratory results, endoscopy and colonoscopy results, length of hospital stay, need of intensive care unit (ICU) admission, and mortality. Mortality rate was the principal endpoint of the study, while duration of hospital stay, required interventional treatment, and admission to the ICU were secondary endpoints. The mean age of patients was 61.92-years-old. Among the 600 total patients, 363 (60.5%) underwent upper gastrointestinal endoscopy and the most frequent diagnoses were duodenal ulcer (19.2%) and gastric ulcer (12.8%). One-hundred-and-fifteen (19.2%) patients required endoscopic treatment, 20 (3.3%) required surgical treatment, and 5 (0.8%) required angiographic embolization. The mean length of hospital stay was 5.21 ± 5.85 d. The mortality rate was 6.3%. The ICU admission rate was 5.3%. Patients with syncope, higher blood glucose levels, and coronary artery disease had significantly higher ICU admission rates (P = 0.029, P = 0.043, and P = 0.002, respectively). Patients with low thrombocyte levels, high creatinine, high international normalized ratio, and high serum transaminase levels had significantly longer hospital stay (P = 0.02, P = 0.001, P = 0.019, and P = 0.005, respectively). Patients who died had significantly higher serum blood urea nitrogen and creatinine levels (P = 0.016 and P = 0.038), and significantly lower mean blood pressure and oxygen saturation (P = 0.004 and P = 0.049). Malignancy and low Glasgow coma scale (GCS) were independent predictive factors of mortality. Prognostic factors for gastrointestinal bleeding in emergency room cases are malignancy, hypotension on admission, low GCS, and impaired kidney function.

Wireless Capsule Endoscopy (WCE) is a relatively new technology (FDA approved in 2002) allowing doctors to view most of the small intestine. Other endoscopies such as colonoscopy, upper gastrointestinal endoscopy, push enteroscopy, and intraoperative enteroscopy could be used to visualize up to the stomach, duodenum, colon, and terminal ileum, but there existed no method to view most of the small intestine without surgery. With the miniaturization of wireless and camera technologies came the ability to view the entire gestational track with little effort. A tiny disposable video capsule is swallowed, transmitting two images per second to a small data receiver worn by the patient on a belt. During an approximately 8-hour course, over 55,000 images are recorded to a worn device and then downloaded to a computer for later examination. Typically, a medical clinician spends more than two hours to analyze a WCE video. Research has been attempted to automatically find abnormal regions (especially bleeding) to reduce the time needed to analyze the videos. The manufacturers also provide the software tool to detect the bleeding called Suspected Blood Indicator (SBI), but its accuracy is not high enough to replace human examination. It was reported that the sensitivity and the specificity of SBI were about 72% and 85%, respectively. To address this problem, we propose a technique to detect the bleeding regions automatically utilizing the Expectation Maximization (EM) clustering algorithm. Our experimental results indicate that the proposed bleeding detection method achieves 92% and 98% of sensitivity and specificity, respectively.

BACKGROUND Many studies have reported an association between periodontal infections and some systemic diseases such as respiratory and cardiovascular diseases. Some studies found a direct association between chronic gastritis caused by Helicobacter pylori (HP) infection and poor periodontal health. METHODS In a cross-sectional study from November 2014 to December 2015 in Kerman, the largest province in southeast Iran, patients with dyspepsia who were candidate for diagnostic upper gastrointestinal (GI) endoscopy were included in our study. Decayed, Missing, and Filled Teeth (DMFT) index and Loe plaque index that are two popular indexes in dental epidemiology were used to assess the oral health by a dentist before the upper GI endoscopy. According to the Loe plaque index, score: 0= no plaque, score: 1= a film of plaque attaching to the free gingival border and near area of the tooth, score: 2= moderate reposition of deposits within the gingival pocket, score :3= plenty of soft matter within the gingival pocket±on the tooth and gingival border. Scores ≤1, 2 and 3 equal to good, moderate, and poor oral hygiene, respectively. During upper GI endoscopy a total of six biopsy samples were taken from fundus, body, and antrum. A pathologist reported these samples according to Sidney's classification into superficial gastritis, atrophic gastritis, intestinal metaplasia, and dysplasia. RESULTS According to Sidney's classification 77 (89.5%) patients had superficial gastritis, 3 (3.5%) had atrophic gastritis, and 6 (7%) had intestinal metaplasia. HP was found in 80.2% of the gastric mucosal biopsy samples. There were not statistically significant relationship between Sidney's classification, presence of HP in gastric mucosal biopsies, and hygiene indicators ( p >0.05). No relation was found between the DMFT index and superficial gastritis, atrophic gastritis, and intestinal metaplasia ( p >0.05). Gastric infection with HP was found in 70%, 75%, and 100% of patients with mild, moderate, and sever DMFT index, respectively. CONCLUSION Our study showed that there might be a relation between poor oral hygiene and gastric precancerous lesions. In addition, HP infection in gastric histopathology might be associated with periodontal disease.

The introduction of propofol (2,6-diisopropylphenol) as a sedative agent has transformed the area of sedation for endoscopic procedures. However, a major drawback of sedation with the use of propofol is its high incidence of injection pain. The most widely used technique in reducing propofol injection pain is through the association of other drugs. The aim of this study was to evaluate the effect of remifentanil-propofol combination on the incidence of propofol injection pain and its influence on the total dose of propofol required for sedation in upper digestive tract endoscopy (UDE) diagnostic tests. One hundred and five patients undergoing upper digestive tract endoscopy were evaluated and randomly divided into 3 groups of 35 patients each. The Control Group received propofol alone; Study-group 1 received remifentanil at a fixed dose of 0.2mg/kg combined with propofol; Study-group 2 received remifentanil at a fixed dose of 0.3mg/kg combined with propofol. The incidence of propofol injection pain and the total dose of propofol required for the test were evaluated. The sample was very similar regarding age, weight, height, sex, and physical status. Statistical analysis was performed according to the nature of the evaluated data. Student's t-test was used to compare the mean of age, weight, height (cm), and dose (mg/kg) variables between groups. The χ(2) test was used to compare sex, physical status, and propofol injection pain between groups. The significance level was α<0.05. There was significant statistical difference between the study groups and the control group regarding the parameters of propofol injection pain and total dose of propofol (mg/kg) used. However, there were no statistical differences between the two study groups for these parameters. We conclude that the use of remifentanil at doses of 0.2mg/kg and 0.3mg/kg was effective for reducing both the propofol injection pain and the total dose of propofol used.

Although intravenous proton pump inhibitor (PPI) has been used for the prevention of post endoscopic submucosal dissection (ESD) bleeding, the route of administration has not been confirmed. The aim of the present study was to compare the efficacy of intravenous and oral PPI administration for the prevention of delayed post ESD bleeding. Total 166 consecutive patients were randomly assigned to 30 mg lansoprazol twice a day (PO group) and 120 mg pantoprazole intravenous injection (IV group) for 48 hours. Finally, 65 patients in PO group and 87 patients in IV group were analyzed. After ESD, all patients underwent follow up endoscopy after 24 hours and were observed the symptoms of bleeding up to 60 days after ESD. Age, sex and use of anticoagulants were not different between groups. At follow up endoscopy after 24 hours, oozing and exposed vessel was noted in 4.6% of PO group and 8.0% of IV group and there was no significant difference. Delayed bleeding occurred in 4 of 65 patients (6.2%) in the PO group and 8 of 87 patients (9.2%) in the IV group (p>0.999). By multivariate analysis, oozing or exposed vessels at follow up endoscopy were risk factors for delayed bleeding (OR=17.5, p=0.022). There was no significant difference in the delayed bleeding, length of hospital stay according to the administration route. Bleeding stigmata at follow up endoscopy was risk factor of delayed bleeding. Oral PPI administration can cost-effectively replace IV PPI for prevention of post ESD bleeding.

The aim was to determine the polyp detection rate and per-patient sensitivity for polyps > 9 mm of colon capsule endoscopy (CCE) compared with colonoscopy as well as the diagnostic accuracy of CCE. Individuals who had a positive immunochemical faecal occult blood test during screening had investigator blinded CCE and colonoscopy. Participants underwent repeat endoscopy if significant lesions detected by CCE were considered to have been missed by colonoscopy. There were 253 participants. The polyp detection rate was significantly higher in CCE compared with colonoscopy (P = 0.02). The per-patient sensitivity for > 9 mm polyps for CCE and colonoscopy was 87% (95% CI: 83-91%) and 88% (95% CI: 84-92%) respectively. In participants with complete CCE and colonoscopy examinations (N = 126), per-patient sensitivity of > 9 mm polyps in CCE (97%; 95% CI: 94-100%) was superior to colonoscopy (89%; 95% CI: 84-94%). A complete capsule endoscopy examination (N = 134) could detect patients with intermediate or greater risk (according to the European guidelines) with an accuracy, sensitivity, specificity and positivity rate of 79%, 93%, 69% and 58% respectively, using a cut-off of at least one polyp > 10 mm or more than two polyps. CCE is superior to colonoscopy in polyp detection rate and per-patient sensitivity to > 9 mm polyps, but only in complete CCE examinations. The rate of incomplete CCE examinations must be improved.

The Agile patency capsule (PC; Given Imaging Ltd, Yoqneam, Israel) is used as a dummy prior to capsule endoscopy (CE) to avoid retention of the CE capsule. However, impaction of the PC's inner radio frequency identification (RFID) tag in a stricture could cause small-bowel ileus. Recently, the RFID tag-less PC was introduced into clinical practice. Herein, we aimed to retrospectively evaluate the usefulness of the tag-less PC. Of 154 patients who were scheduled to undergo CE, 100 consecutive patients (65%) who underwent PC evaluation were enrolled in the present study. Primary study end point was the retention rate of the CE capsule after successful passage of the PC. Secondary end point was analysis of the significant factors affecting the passage of the PC. In total, 87 patients (87%) had bowel patency confirmed by PC evaluation. There was no capsule retention in any of these 87 patients during CE. Abnormal findings were obtained from 60 CE, and 41 patients received new or modified treatment. Multivariate analysis of factors related to the confirmation of patency demonstrated that stenosis on imaging was the most influential factor (P = 0.002, odds ratio 16.387). The results confirmed that passage of the PC depends on stenosis on imaging. Use of the tag-less PC confirmed gastrointestinal tract patency for most of the patients who did not have stenosis on imaging and allowed estimation of the patency for patients who did have stenosis on imaging. © 2014 The Authors.

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.

The aim of the study is to examine the importance of Rockall scoring system in long-term setting to estimate re-bleeding and mortality rate due to upper gastrointestinal bleeding. A total of 321 patients who had been treated for upper gastrointestinal bleeding were recruited to the study. Patients' demographic and clinical data, the amount of blood transfusion, endoscopy results, and Rockall scores were retrieved from patients' charts. The re-bleeding, morbidity, and mortality rates were noted after 3 years of follow-up with telephone. Re-bleeding rate was statistically significantly higher in Rockall 4 group compared to Rockall 0 group. Mortality rate was also statistically significantly higher in Rockall 4 group. Rockall risk scoring system is a valuable tool to predict re-bleeding and mortality rates for patients with upper gastrointestinal bleeding in long-term setting.

In this paper we are reporting one case of exsanguinating upper gastrointestinal tract (GIT) bleed requiring massive blood transfusion and immediate life saving surgery. A 30 years old female, 12 weeks pregnant was referred to our hospital from the earth-quake affected area of Kashmir with history of upper abdominal pain, haematemesis and melaena for one week. After stabilizing the patient, upper gastro-intestinal endoscopy was performed. It revealed gastric ulcer just distal to the gastro-esophageal junction on the lesser curvature. Biopsy from the ulcer edge led to profuse spurting of the blood and patient went into state of shock. Immediate resuscitation led to rebleeding and recurrence of post haemorrahagic shock. The patient was immediately explored and total gastrectectomy with splenectomy concluded as life saving procedure. A review of literature was conducted to make this report possible.

Drug-induced sleep endoscopy (DISE) is a new tool in the work-up of patients with sleep-disordered breathing (SDB). We assessed the impact of DISE on the treatment plan of snoring patients. This is a single institution prospective longitudinal clinical trial. The setting is a private teaching hospital. A consecutive series of 100 snoring patients prospectively underwent a standardised questionnaire, clinical examination, rhinomanometry, allergy skin prick testing, DISE and polysomnography. Management plan before and after DISE evaluation was compared. In 61 patients (excluding 16 patients sent for continuous positive airway pressure, three patients refused sleep endoscopy and 20 were lost to follow-up), we compared the treatment plans. DISE showed single level airway collapse in 13 and multilevel collapse in 48 patients. The site of flutter did not add additional information as compared to the pattern and the location of the collapse. After DISE, the initial management plan changed in 41% of patients irrespective of the type of initial management plan. The only somewhat accurate initial treatment plan was uvulopalatopharyngoplasty (unchanged in 11/13 patients). Excluding moderate to severe obstructive sleep apnea patients DISE is an indispensable tool in treatment decision in all SDB patients. We suggest to simplify the protocol for DISE reporting.

AIM: To evaluate the full-spectrum endoscopy (FUSE) colonoscopy system as the first report on the utility thereof in a Korean population. METHODS: We explored the efficacy of the FUSE colonoscopy in a retrospective, single-center feasibility study performed between February 1 and July 20, 2015. A total of 262 subjects (age range: 22-80) underwent the FUSE colonoscopy for colorectal cancer screening, polyp surveillance, or diagnostic evaluation. The cecal intubation success rate, the polyp detection rate (PDR), the adenoma detection rate (ADR), and the diverticulum detection rate (DDR), were calculated. Also, the success rates of therapeutic interventions were evaluated with biopsy confirmation. RESULTS: All patients completed the study and the success rates of cecal and terminal ileal intubation were 100% with the FUSE colonoscope; we found 313 polyps in 142 patients and 173 adenomas in 95. The overall PDR, ADR and DDR were 54.2%, 36.3%, and 25.2%, respectively, and were higher in males, and increased with age. The endoscopists and nurses involved considered that the full-spectrum colonoscope improved navigation and orientation within the colon. No colonoscopy was aborted because of colonoscope malfunction. CONCLUSION: The FUSE colonoscopy yielded a higher PDR, ADR, DDR than did traditional colonoscopy, without therapeutic failure or complications, showing feasible, effective, and safe in this first Korean trial.

In the expanded indications for endoscopic resection, Japanese guidelines for gastric cancer include differentiated cancers confined to the mucosa with an ulcer <30 mm. We describe a patient with lymph node metastasis after curative endoscopic submucosal dissection (ESD) for a tumor of this indication. The patient was a 70-year-old man with chronic hepatitis C. He underwent ESD for early gastric cancer in May 2010. Pathology revealed a moderately differentiated adenocarcinoma, 22 × 17 mm in size, that was confined to the mucosa with an ulcer. The horizontal and vertical margins were negative for the tumor. We diagnosed thiscase as curative resection of expanded indication and followed this patient with endoscopy, abdominal ultrasonography (AUS) or enhanced computed tomography (CT) approximately every 6 months. After 17 months, lymph node metastasis was detected with AUS and CT and diagnosed by endoscopic ultrasound-guided fine-needle aspiration biopsy in August 2011. Distal gastrectomy with D2 dissection was carried out in December 2011. Although it is low, the possibility of recurrence should be borne in mind after endoscopic treatment of early gastric cancer, despite its inclusion in the expanded indications for endoscopic resection. © 2014 The Authors.

The purpose of this research was to investigate the usefulness of three-dimensional (3D) endoscopy compared with two-dimensional (2D) endoscopy in neuroendoscopic surgeries in a comparative study and to test the clinical applications. Forty-three examinees were divided into three groups according to their endoscopic experience: novice, beginner, or expert. Examinees performed three separate tasks using 3D and 2D endoscopy. A recently developed 3D high-definition (HD) neuroendoscope, 4.7 mm in diameter (Shinko Optical Co., Ltd., Tokyo, Japan) was used. In one of the three tasks, we developed a full-sized skull model of acrylic-based plastic using a 3D printer and a patient's thin slice computed tomography data, and evaluated the execution time and total path length of the tip of the pointer using an optical tracking system. Sixteen patients underwent endoscopic transnasal transsphenoidal pituitary surgery using both 3D and 2D endoscopy. Horizontal motion was evaluated using task 1, and anteroposterior motion was evaluated with task 3. Execution time and total path length in task 3 using the 3D system in both novice and beginner groups were significantly shorter than with the 2D system (p < 0.05), although no significant difference between 2D and 3D systems in task 1 was seen. In both the novice and beginner groups, the 3D system was better for depth perception than horizontal motion. No difference was seen in the expert group in this regard. The 3D HD endoscope was used for the pituitary surgery and was found very useful to identify the spatial relationship of carotid arteries and bony structures. The use of a 3D neuroendoscope improved depth perception and task performance. Our results suggest that 3D endoscopes could shorten the learning curve of young neurosurgeons and play an important role in both general surgery and neurosurgery.

[Gastrointestinal bleeding--concepts of surgical therapy in the upper gastrointestinal tract].

PubMed

Knoefel, W T; Rehders, A

2006-02-01

Bleeding of the upper gastrointestinal tract is the main symptom of a variety of possible conditions and still results in considerable mortality. Endoscopy is the first diagnostic modality, enabling rapid therapeutic intervention. In case of intractable or relapsing bleeding, surgery is often inevitable. However, emergency operations result in significantly higher mortality rates. Therefore the option of early elective surgical intervention should be considered for patients at increased risk of relapsing bleeding. If bleeding is symptomatic due to a complex underlying condition such as hemosuccus pancreaticus or hemobilia, angiography is now recognized as the definitive investigation. Angiographic hemostasis can be achieved in most cases. Due to the underlying condition, surgical management still remains the mainstay in treating these patients. This paper reviews surgical strategy in handling upper gastrointestinal bleeding.

Management of Upper Gastrointestinal Bleeding in Children: Variceal and Nonvariceal.

PubMed

Lirio, Richard A

2016-01-01

Upper gastrointestinal (UGI) bleeding is generally defined as bleeding proximal to the ligament of Treitz, which leads to hematemesis. There are several causes of UGI bleeding necessitating a detailed history to rule out comorbid conditions, medications, and possible exposures. In addition, the severity, timing, duration, and volume of the bleeding are important details to note for management purposes. Despite the source of the bleeding, acid suppression with a proton-pump inhibitor has been shown to be effective in minimizing rebleeding. Endoscopy remains the interventional modality of choice for both nonvariceal and variceal bleeds because it can be diagnostic and therapeutic. Copyright © 2016 Elsevier Inc. All rights reserved.

Patient-to-patient transmission of hepatitis C virus (HCV) during colonoscopy diagnosis

PubMed Central

2010-01-01

Background No recognized risk factors can be identified in 10-40% of hepatitis C virus (HCV)-infected patients suggesting that the modes of transmission involved could be underestimated or unidentified. Invasive diagnostic procedures, such as endoscopy, have been considered as a potential HCV transmission route; although the actual extent of transmission in endoscopy procedures remains controversial. Most reported HCV outbreaks related to nosocomial acquisition have been attributed to unsafe injection practices and use of multi-dose vials. Only a few cases of likely patient-to-patient HCV transmission via a contaminated colonoscope have been reported to date. Nosocomial HCV infection may have important medical and legal implications and, therefore, possible transmission routes should be investigated. In this study, a case of nosocomial transmission of HCV from a common source to two patients who underwent colonoscopy in an endoscopy unit is reported. Results A retrospective epidemiological search after detection of index cases revealed several potentially infective procedures: sample blood collection, use of a peripheral catheter, anesthesia and colonoscopy procedures. The epidemiological investigation showed breaches in colonoscope reprocessing and deficiencies in the recording of valuable tracing data. Direct sequences from the NS5B region were obtained to determine the extent of the outbreak and cloned sequences from the E1-E2 region were used to establish the relationships among intrapatient viral populations. Phylogenetic analyses of individual sequences from viral populations infecting the three patients involved in the outbreak confirmed the patient pointed out by the epidemiological search as the source of the outbreak. Furthermore, the sequential order in which the patients underwent colonoscopy correlates with viral genetic variability estimates. Conclusions Patient-to-patient transmission of HCV could be demonstrated although the precise route of transmission remained unclear. Viral genetic variability is proposed as a useful tool for tracing HCV transmission, especially in recent transmissions. PMID:20825635

Background & Aims Abdominal obesity increases the risk of gastroesophageal reflux disease (GERD) and might also contribute to development of Barrett's esophagus (BE), although results are inconsistent. We examined the effects of waist-to-hip ratio (WHR) and body mass index (BMI) on the risk of BE and investigated whether race, GERD symptoms, or hiatus hernia were involved. Methods We conducted a case-control study using data from eligible patients who underwent elective esophagogastroduodenoscopy (EGD); 237 had BE and the other 1021 served as endoscopy controls. We also analyzed data and tissue samples from enrolled patients who were eligible for screening colonoscopies at a primary care clinic (colonoscopy controls, n=479). All patients underwent EGD, completed a survey, and had anthropometric measurements taken. WHR was categorized as high if was ≥0.9 for men and ≥0.85 for women. Data were analyzed with logistic regression. Results There was no association between BMI and BE. However, more patients with BE had a high WHR (92.4%) than endoscopy controls (79.5%) or colonoscopy controls (84.6%) (P<.001 and P=.008, respectively). In adjusted analysis, patients with BE were 2-fold more likely to have a high WHR than endoscopy controls (odds ratio [OR], 1.93; 95% confidence interval [CI], 1.1– 3.5), this association was stronger for patients with long-segment BE (OR, 2.81; 95% CI, 1.0−7.9). A high WHR was significantly associated with BE only in Whites (OR=2.5; 95% CI, 1.2–5.4)—not in Blacks or Hispanics. GERD symptoms, hiatus hernia, or gastroesophageal valve flap grade could not account for the association. Conclusions High WHR, but not BMI, is associated with a significant increase in the risk of BE, especially long-segment BE and in Whites. The association is not due to GERD symptoms or hiatus hernia.

Background and aims  Early ( < 24 hours) esophagogastroduodenoscopy (EGD) is used to prognosticate mucosal injury after caustic ingestion. We aimed to compare differences in endoscopic grading on EGDs performed on day 5 and day 1 and to assess the impact of relook endoscopy findings on the development of esophageal and/or antropyloric cicatrization. Patients and methods  Consecutive patients admitted within 24 hours of caustic ingestion between 2009 and 2014 underwent EGD and had their mucosal changes graded. Injuries of grade ≤ 2a were classified as mild and ≥ 2b were classified as severe. Patients were followed up for the development of cicatrization and managed per protocol. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and likelihood ratios (LRs) were calculated to compare day 1 and day 5 EGD findings. Results  A total of 62 patients (35 men; mean age 33 ± 15) underwent both day 1 and day 5 EGDs. Antropyloric stenosis developed in 16 patients, esophageal strictures in nine, and four had both esophageal and antropyloric strictures. Compared with day 1 EGD, endoscopic grading of severe injury on day 5 had higher specificity (83 % vs. 65 %), higher PPV (60 % vs. 41 %), and higher positive LR (5.65 vs. 2.66) for predicting the development of esophageal stricture. Similarly, day 5 endoscopic grading had higher specificity (95 % vs. 61 %), higher PPV (88 % vs. 54 %), and higher positive LR (16 vs. 2.5) for predicting the development of antropyloric stenosis. Conclusion  Endoscopic assessment on day 5 is a better predictor of esophageal and gastric cicatrization than day 1 EGD, which significantly overestimates the grade of injury. © Georg Thieme Verlag KG Stuttgart · New York.

Gastrointestinal (GI) bleeding is a common surgical problem. The aim of this study was to evaluate how insertion of the nasogastric tube may enable differentiation between upper and lower GI bleeding in patients with melena. A retrospective study involving patients admitted to our surgery division with a melena was carried out between the years 2010 and 2012. A total of 386 patients were included in the study. Of these, 279 (72.2%) patients had negative nasogastric aspirate. The sensitivity of examination of nasogastric aspirate to establish the upper GI as the source of bleeding was only 28% and the negative predictive value of a negative nasogastric aspirate was less than 1%. Most patients who initially presented with melena and were found to have upper GI bleeding had a negative nasogastric aspirate. Insertion of a nasogastric tube does not affect the clinical decision to perform upper endoscopy and should not be routinely carried out.

Endoscopy in screening for digestive cancer

Lambert, René

2012-01-01

The aim of this study is to describe the role of endoscopy in detection and treatment of neoplastic lesions of the digestive mucosa in asymptomatic persons. Esophageal squamous cell cancer occurs in relation to nutritional deficiency and alcohol or tobacco consumption. Esophageal adenocarcinoma develops in Barrett’s esophagus, and stomach cancer in chronic gastric atrophy with Helicobacter pylori infection. Colorectal cancer is favoured by a high intake in calories, excess weight, low physical activity. In opportunistic or individual screening endoscopy is the primary detection procedure offered to an asymptomatic individual. In organized or mass screening proposed by National Health Authorities to a population, endoscopy is performed only in persons found positive to a filter selection test. The indications of primary upper gastrointestinal endoscopy and colonoscopy in opportunistic screening are increasingly developing over the world. Organized screening trials are proposed in some regions of China at high risk for esophageal cancer; the selection test is cytology of a balloon or sponge scrapping; they are proposed in Japan for stomach cancer with photofluorography as a selection test; and in Europe, America and Japan; for colorectal cancer with the fecal occult blood test as a selection test. Organized screening trials in a country require an evaluation: the benefit of the intervention assessed by its impact on incidence and on the 5 year survival for the concerned tumor site; in addition a number of bias interfering with the evaluation have to be controlled. Drawbacks of screening are in the morbidity of the diagnostic and treatment procedures and in overdetection of none clinically relevant lesions. The strategy of endoscopic screening applies to early cancer and to benign adenomatous precursors of adenocarcinoma. Diagnostic endoscopy is conducted in 2 steps: at first detection of an abnormal area through changes in relief, in color or in the course of superficial capillaries; then characterization of the morphology of the lesion according to the Paris classification and prediction of the risk of malignancy and depth of invasion, with the help of chromoscopy, magnification and image processing with neutrophil bactericidal index or FICE. Then treatment decision offers 3 options according to histologic prediction: abstention, endoscopic resection, surgery. The rigorous quality control of endoscopy will reduce the miss rate of lesions and the occurrence of interval cancer. PMID:23293721

Laparoscopy shows superiority over endoscopy for early detection of malignant atrophic papulosis gastrointestinal complications: a case report and review of literature.

The malignant form of atrophic papulosis (Köhlmeier-Degos disease) is a rare thrombo-occlusive vasculopathy that can affect multiple organ systems. Patients typically present with distinctive skin lesions reflective of vascular drop out. The small bowel is the most common internal organ involved, resulting in considerable morbidity and mortality attributable to ischemic microperforations. Determination of the presence of gastrointestinal lesions is critical in distinguishing systemic from the benign, cutaneous only disease and in identifying candidates for treatment. We describe an 18 year old male who first presented with cutaneous atrophic papulosis but became critically ill from small bowel microperforations. He had an almost immediate and dramatic response to treatment. Prior to his presentation with acute abdomen he had upper and lower endoscopy showing areas of nonspecific patchy erythema. At laparotomy, innumerable characteristic lesions with central pearly hue and erythematous border were seen. PubMed was used for a literature search using the keywords malignant atrophic papulosis, Degos disease, endoscopy, laparoscopy and laparotomy. This search yielded 200 articles which were further analyzed for diagnostic procedures and findings. Among the 200 articles we identified only 11 cases in which endoscopy was performed. Results of endoscopy and laparotomy in our patient with malignant atrophic papulosis were compared to those in the literature. Endoscopy of the gastrointestinal tract has shown gastritis and non-specific inflammation whereas laparoscopy shows white plaques with red borders on the serosal surface of the small bowel and the peritoneum. From personal communications with other physicians worldwide, we identified three additional unpublished cases in which endoscopy revealed only minimal changes while laparoscopy showed dramatic lesions. From our experience the endoscopic findings are often subtle and nonspecific, whereas laparascopy or laparotomy will reveal pathognomic lesions on the serosal surface of the intestine. Our report contrasts the endoscopic and laparoscopic findings in malignant atrophic papulosis which suggest laparoscopy is the more powerful means of detecting gastrointestinal involvement. Imaging studies may serve as a key indicator of systemic progression. Based on our experience, laparoscopy should be performed when there is a high index of suspicion for gastrointestinal malignant atrophic papulosis, even if endoscopic examination is non-diagnostic or normal.

Capsule Endoscopy in the Assessment of Obscure Gastrointestinal Bleeding: An Evidence-Based Analysis

PubMed Central

2015-01-01

Background Obscure gastrointestinal bleeding (OGIB) is defined as persistent or recurrent bleeding associated with negative findings on upper and lower gastrointestinal (GI) endoscopic evaluations. The diagnosis and management of patients with OGIB is particularly challenging because of the length and complex loops of the small intestine. Capsule endoscopy (CE) is 1 diagnostic modality that is used to determine the etiology of bleeding. Objectives The objective of this analysis was to review the diagnostic accuracy, safety, and impact on health outcomes of CE in patients with OGIB in comparison with other diagnostic modalities. Data Sources A literature search was performed using Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid Embase, the Wiley Cochrane Library, and the Centre for Reviews and Dissemination database, for studies published between 2007 and 2013. Review Methods Data on diagnostic accuracy, safety, and impact on health outcomes were abstracted from included studies. Quality of evidence was assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results The search yielded 1,189 citations, and 24 studies were included. Eight studies reported diagnostic accuracy comparing CE with other diagnostic modalities. Capsule endoscopy has a higher sensitivity and lower specificity than magnetic resonance enteroclysis, computed tomography, and push enteroscopy. Capsule endoscopy has a good safety profile with few adverse events, although comparative safety data with other diagnostic modalities are limited. Capsule endoscopy is associated with no difference in patient health-related outcomes such as rebleeding or follow-up treatment compared with push enteroscopy, small-bowel follow-through, and angiography. Limitations There was significant heterogeneity in estimates of diagnostic accuracy, which prohibited a statistical summary of findings. The analysis was also limited by the fact that there is no established reference standard to which the diagnostic accuracy of CE can be compared. Conclusions There is very-low-quality evidence that CE has a higher sensitivity but a lower specificity than other diagnostic modalities. Capsule endoscopy has few adverse events, with capsule retention being the most serious complication. Capsule endoscopy is perceived by patients as less painful and less burdensome compared with other modalities. There is low-quality evidence that patients who undergo CE have similar rates of rebleeding, further therapeutic interventions, and hospitalization compared with other diagnostic modalities.

The objective of our study was to report the technique, complications, and clinical outcomes of interventional radiology-operated cholecystoscopy with stone removal for the management of symptomatic cholelithiasis. Ten (77%) men and three (23%) women (mean age, 65 years) with symptomatic cholelithiasis underwent cholecystostomy followed by interventional radiology-operated cholecystoscopy with stone removal. Major comorbidities precluding cholecystectomy included prior cardiac, pulmonary, or abdominal surgery; cirrhosis; sepsis with hyponatremia; seizure disorder; developmental delay; and cholecystoduodenal fistula. Cholecystostomy access, time between cholecystostomy and cholecystoscopy, endoscopic and fragmentation devices used, technical success, procedure time, fluoroscopy time, complications, length of hospital stay, time between cholecystoscopy and cholecystostomy removal, follow-up, and acute cholecystitis recurrence were recorded. Eleven (85%) patients underwent transhepatic cholecystostomy, and two (15%) patients underwent transperitoneal cholecystostomy. The mean time from cholecystostomy to cholecystoscopy was 151 days. Flexible endoscopy was used in eight (62%) patients, rigid endoscopy in three (23%), and both flexible and rigid in two (15%). Electrohydraulic lithotripsy was used in eight procedures, nitinol baskets in seven, ultrasonic lithotripsy in two, and percutaneous thrombectomy devices in one. Primary technical success was achieved in 11 (85%) patients, and secondary technical success was achieved in 13 (100%) patients. The mean procedure time was 164 minutes, and the mean number of procedures required to clear all gallstones was 1. One (8%) patient developed acute pancreatitis, and one (8%) patient died of gastrointestinal hemorrhage. The median hospital length of stay after cholecystoscopy was 1 day for postoperative monitoring. The mean time between cholecystoscopy and cholecystostomy removal was 39 days. One (8%) patient developed recurrent acute cholecystitis 1095 days after cholecystoscopy. Interventional radiology-operated cholecystoscopy may serve as an effective method for percutaneous gallstone removal in patients with multiple comorbidities precluding cholecystectomy.

To analyze the clinical characteristics, outcomes and prognostic factors in elderly patients (aged 75 years and elder) with acute nonvariceal upper gastrointestinal bleeding (UGIB). Consecutive patients admitted with acute nonvariceal UGIB who underwent upper gastrointestinal endoscopy were prospectively recruited and subdivided into two age-based groups, elderly (aged ≥75 years) and younger patients (<75 years). The patients' characteristics and outcomes were recorded. Altogether 1136 patients were included in the study, 276 (24.3%) aged ≥75 years. Peptic ulcers, gastroduodenal erosions and esophagitis represented the three most common endoscopic lesions found in 87.7% of the elderly patients compared with 80.8% in younger patients ( P  = 0.008). Overall, the rebleeding rate (4.0% vs 3.3%, P = 0.568), need for blood transfusion (66.3% vs 61.0%, P = 0.122), surgery rate (1.2% vs 1.4%, P = 0.947) and in-hospital mortality (13.0% vs 10.0%, P = 0.157) were not different between the two groups. In elderly patients, serum albumin was the only predictive variable independently associated with mortality in the overall analysis (OR 5.867, 95% CI 2.206-15.604, P < 0.001) and in the subgroup patients with peptic ulcers (OR 5.230, 95% CI 2.099-13.029, P = 0.001). Elderly patients with serum albumin >23.5 g/L at admission presented a low mortality (negative predictive value 97.3%). Clinical evolution and mortality do not differ between the elderly and younger patients with acute nonvariceal UGIB. Serum albumin level at admission is a prognostic marker for mortality in elder patients. © 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.

Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is a method broadly used for gastric cancer screening in Japan. Gastric polyp is one of the most frequent findings detected by UGI-XR, but how to handle it remains controversial. Gastric polyps of the 17,264 generally healthy subjects in Japan who underwent UGI-XR or upper gastrointestinal endoscopy (UGI-ES) in 2010 were analyzed. Of the 6,433 UGI-XR examinees (3,405 men and 3,028 women, 47.4 ± 9.0 years old), gastric polyps were detected in 464 men (13.6 %) and 733 women (24.2 %) and were predominantly developed on the non-atrophic gastric mucosa (p < 0.0001). Multiple logistic regression analysis showed that the presence of gastric polyps has significant association with lower value of serum anti-Helicobacter pylori IgG titer, female gender, lighter smoking habit, older age, and normal range of body mass index (≥18.5 and <25), but not with drinking or serum pepsinogen I/II ratio. During the 3-year follow-up, gastric cancer occurred in 7 subjects (0.11 %), but none of them had gastric polyps at the beginning of the follow-up period. Of the 2,722 subjects with gastric polyps among the 10,831 UGI-ES examinees in the same period, 2,446 (89.9 %) had fundic, 267 (9.8 %) had hyperplastic, and 9 (0.3 %) had adenomatous/cancerous polyps. Gastric polyps diagnosed by UGI-XR predominantly arise on the Helicobacter pylori-negative gastric mucosa with a low risk of gastric cancer in Japan. In the prospective observation, none of the UGI-XR examinees with gastric polyps developed gastric cancer for at least 3 years subsequently.

AIM: To compare the mid-term outcomes of laparoscopic calibrated Nissen-Rossetti fundoplication with Dor fundoplication performed after Heller myotomy for oesophageal achalasia. METHODS: Fifty-six patients (26 men, 30 women; mean age 42.8 ± 14.7 years) presenting for minimally invasive surgery for oesophageal achalasia, were enrolled. All patients underwent laparoscopic Heller myotomy followed by a 180° anterior partial fundoplication in 30 cases (group 1) and calibrated Nissen-Rossetti fundoplication in 26 (group 2). Intraoperative endoscopy and manometry were used to calibrate the myotomy and fundoplication. A 6-mo follow-up period with symptomatic evaluation and barium swallow was undertaken. One and two years after surgery, the patients underwent symptom questionnaires, endoscopy, oesophageal manometry and 24 h oesophago-gastric pH monitoring. RESULTS: At the 2-year follow-up, no significant difference in the median symptom score was observed between the 2 groups (P = 0.66; Mann-Whitney U-test). The median percentage time with oesophageal pH < 4 was significantly higher in the Dor group compared to the Nissen-Rossetti group (2; range 0.8-10 vs 0.35; range 0-2) (P < 0.0001; Mann-Whitney U-test). CONCLUSION: Laparoscopic Dor and calibrated Nissen-Rossetti fundoplication achieved similar results in the resolution of dysphagia. Nissen-Rossetti fundoplication seems to be more effective in suppressing oesophageal acid exposure. PMID:21876635

Despite recent advances in enteroscopy, such as balloon enteroscopy, accessing the small intestine remains challenging. Spiral enteroscopy is a novel technique in which an endoscope is fitted with a rotating overtube that has a soft spiral fin at the tip. Whereas spiral enteroscopy is beginning to be carried out in Western countries, it is not common in many Asian countries. The aim of the present study was to evaluate the efficacy and safety of spiral enteroscopy in Japanese patients. We prospectively conducted spiral enteroscopy in patients with suspected or known small bowel disease. All procedures were carried out using a spiral overtube. The main outcome measurements of the study were diagnosis rate, endoscopic intervention rate, and complication rate. Thirty-two patients underwent spiral enteroscopy. Spiral enteroscopy diagnosed 16 patients (50%) with small intestinal lesions, including six malignant lymphomas (19%), three erosions or ulcers (9%), three polyps (9%), two angioectasias (6%), one carcinoma (3%), and one submucosal tumor (3%). Additionally, four patients underwent endoscopic interventions (13%). Mallory-Weiss syndrome occurred in one patient (3%). No perforation occurred in any patient (0%). Our initial experience of spiral enteroscopy suggests that it can be introduced safely, but it is relatively invasive and technically demanding. More experience is needed to conduct spiral enteroscopy easily and safely. © 2012 The Authors. Digestive Endoscopy © 2012 Japan Gastroenterological Endoscopy Society.

A 75-year-old male who underwent an Ivor Lewis esophagectomy due to a distal adenocarcinoma had a leak at the gastroplasty on the 5th day after surgery, which required two surgeries and a primary suture. He was transferred to our hospital due to a poor outcome and endoscopy revealed a 2.5cm gap perianastomotically on the gastroplasty wall, for which a stent was placed. Due to hemodynamic impairment, a thoracotomy procedure was performed, which revealed stent protrusion into the cavity. The patient underwent an esophagogastric anastomosis resection, cervical esophagostomy and gastrostomy. Sepsis was resolved postoperatively and the patient had a protracted stay in the PACU due to poor respiratory dynamics following a prolonged intubation.

The aim of this study is to evaluate a functional correlation between the pancreas and the small intestine and the association of this relationship with nutritional status, using magnifying enteroscopy. The subjects were adults aged 20 years or older who underwent upper gastrointestinal endoscopy. An endoscope was inserted into the jejunum, and 10% glucose was sprayed under magnifying observation to evaluate changes in blood flow in the villous capillary network. Mucosal biopsy was performed before and after spraying to evaluate the incretin response in the jejunal mucosa. A total of 124 patients participated in the study. There was a positive correlation between villous blood flow change and exocrine pancreas function (R = 0.4337, P < 0.0001). Changes of gastric inhibitory polypeptide and glucagon-like peptide messenger RNAs in biopsy samples were positively correlated with endocrine pancreas function in 88 patients without treatment for diabetes (R = 0.4314, P = 0.0012; R = 0.4112, P = 0.0081). In patients with lower villous blood flow change and decreased pancreatic exocrine function, the prognostic nutritional index were significantly lower (P = 0.0098), compared with other patients. This study provides the first evidence of a close functional correlation between the pancreas and the small intestine.

The aim of this study was to evaluate patient's experience when performing transnasal flexible endoscopy using EndoSheath Technology without sedation in an ENT outpatient department. Patients were seen at the laryngological clinic of the Department of Otorhinolaryngology, Head and Neck Surgery, University Hospital Heidelberg, presenting with complaints of reflux like throat cleaning, persistent cough, globus sensation, heartburn, or voice problems. First, we performed stroboscopy. In cases where physical examination findings revealed the presence of LPR, we performed a transnasal flexible esophagoscopy (TNE) using sterile EndoSheath Technology under local anesthesia. 55 patients were investigated and completed a questionnaire on subjective discomfort that they felt during the procedure. The different steps of the examination were assessed separately. Complications were noted down by the surgeon. All patients underwent a complete examination of the upper aerodigestive tract. The time needed for preparation, examination and cleaning measures was recorded as well. The average preparation time for each examination was 24 min. No complications were observed during the procedure. The procedure was well tolerated by all patients and was classified on average as "low-grade unpleasant". In summary, TNE is a safe, quick and well-tolerated procedure that can be performed in a regular examination room under local anesthesia without sedation.

Successful preoperative diagnosis of a branchial cyst requires a systematic approach. The aim of this study was to evaluate methods of investigation of a lateral neck swelling suspicious for a branchial cyst, and to highlight cases where a less benign cause for the swelling should be suspected and therefore management altered appropriately. A retrospective case study of 24 patients with presumed branchial cysts managed operatively was undertaken. Demographic, clinical, imaging, cytology and histopathological data were analysed to formulate an approach to the work-up of a lateral neck swelling suspected to be a branchial cyst. All 24 patients presented with a lateral neck mass thought to be a branchial cyst preoperatively underwent preoperative fine-needle aspiration cytology. The overall accuracy of cytology in predicting a benign branchial cyst histopathologically was 83.3% (20 out of 24). Successful preoperative diagnosis of a branchial cyst requires a combination of imaging and cytology. If there is concern that a lateral neck swelling is not a branchial cyst on clinical, imaging or cytological features, then a full preoperative work-up, including computed tomography scan of the neck and upper aero-digestive tract endoscopy should be performed, prior to an excisional biopsy. © 2011 The Authors.

Excessive flatulence which impairs social performance in patients is one of the common reasons for referrals to gastroenterology clinics. Celiac Disease is a rare but important cause of increased intestinal gas (bloating) and if not diagnosed, patients face complications such as malabsorption, anemia, osteoporosis and even intestinal lymphoma. This study aimed to determine the frequency of Celiac Disease in patients with excessive flatulence.One hundred and fifty patients with a chief complaint of experiencing flatulence more than 15 times a day and lasting for three months were referred to the gastroenterology clinic of Rasoul-e-Akram Teaching Hospital. Serological tests for Celiac Disease, Anti TTG Ab (IgA-IgG) were requested and the patients with positive tests underwent upper GI endoscopy. Biopsies of the second part of the duodenum were then sent to the laboratory.From one hundred and thirty patients who completed the study, 92 (70.7%) were female. Mean age of the patients was 32 ± 13 years. Anti TTG Ab was found in 5 patients (3.85%). Only 2 patients (1.5%) had a documented positive pathology for Celiac Disease.According to the results of this study and other studies, we conclude that Celiac Disease is an uncommon etiology for excessive flatulence but it is of importance to investigate it in excessive flatulence patients.

Testicular cancer is the most common solid malignancy affecting males between the ages of 15 and 35. The symptomatology caused by this tumor varies according to the site of metastasis. We present the case of a 26-year-old male who arrived to the emergency department with hematemesis. He had no previous medical history. On arrival, we noted enlargement of the left scrotal sac. There was also a mass in the left scrotum which provoked displacement of the penis and right testis. The serum alpha-fetoprotein level was 17,090 ng/mL, lactate dehydrogenase was 1480 U/L, and human chorionic gonadotropin was 287.4 IU/mL. Upper endoscopy revealed a type 1 isolated gastric varix, treated with cyanoacrylate. A CT scan showed extrinsic compression of the portal vein by lymphadenopathy along with splenic vein partial thrombosis, which caused left-sided portal hypertension. Neoadjuvant chemotherapy was started with etoposide and cisplatin, and seven days later the patient underwent left radical orchiectomy. A postoperative biopsy revealed a pure testicular teratoma. Noncirrhotic left portal hypertension with bleeding from an isolated gastric varix secondary to metastasic testicular cancer has not been described before. Clinicians must consider the possibility of malignancy in the differential diagnosis of a young man presenting with unexplained gastrointestinal bleeding.

To evaluate the feasibility, safety, and efficacy of laparoscopic pancreaticoduodenectomy (LPD) using a reverse-"V" approach with four ports. This is a retrospective study of selected patients who underwent LPD at our center between April 2011 and April 2012. The following data were collected and reviewed: patient characteristics, tumor histology, surgical outcome, resection margins, morbidity, and mortality. All patients were thoroughly evaluated preoperatively by complete hematologic investigations, triple-phase helical computed tomography, upper gastrointestinal endoscopy, and biopsy of ampullary lesions (when present). Magnetic resonance cholangiopancreatography was performed for doubtful cases of lower common bile duct lesions. There was no perioperative mortality. LPD was performed with tumor-free margins in all patients, including patients with pancreatic ductal adenocarcinoma (n = 6), ampullary carcinoma (n = 6), intra-ductal papillary mucinous neoplasm (n = 2), pancreatic cystadenocarcinoma (n = 2), pancreatic head adenocarcinoma (n = 3), and bile duct cancer (n = 2). The mean patient age was 65 years (range, 42-75 years). The median blood loss was 240 mL, and the mean operative time was 368 min. LPD using a reverse-"V" approach can be performed safely and yields good results in elective patients. Our preliminary experience showed that LDP can be performed via a reverse-"V" approach. This approach can be used to treat localized malignant lesions irrespective of histopathology.

2017-02-01

Alpha-fetoprotein (AFP)-producing esophageal adenocarcinoma (EAC) is a rare occurrence. Elevation of serum AFP is commonly associated with hepatocellular carcinoma and yolk sac tumors, but rarely with esophageal carcinoma. Here, we report a rare case of AFP-producing EAC. A 51-year-old man presented with two weeks of acid reflux and a 35-lb weight loss. Laboratory data were notable for transaminitis and AFP was 2524 ng/mL. Computed tomography of the abdomen revealed abnormal thickening of the esophagus and multiple metastatic masses throughout the liver. Biopsy of one of the masses revealed adenocarcinoma of gastrointestinal origin. Subsequent upper endoscopy revealed an esophageal mass with biopsy notable for ulcerated dysplastic glandular mucosa with likely underlying malignancy. The patient underwent palliative esophageal stent placement but died two months later. Elevated AFP levels are an unusual occurrence in EAC. Prognosis is poor given its advanced presenting stage and high metastatic potential. Most cases are unsuccessfully treated with surgery and chemotherapy. Serial measurement of serum AFP may be useful for monitoring clinical status and treatment response. Clinicians should consider AFP-producing EAC in their differential diagnosis in the work-up of a liver mass in the setting of elevated AFP or liver function impairment, especially in the absence of chronic liver disease.

Neurologically impaired children (NIC) have a high risk of recurrence of gastroesophageal reflux (GER) following fundoplication. A postpyloric feeding tube may be useful when gastric emptying disorders occur; however, dislocation and difficulty in feeding management often require more aggressive procedures. Total esophagogastric dissociation (Bianchi's TEGD) is an alternative to the classic fundoplication procedure, whereas laparoscopic gastric bypass is a frequently performed procedure in morbid obesity, improving gastric outlet. The aim of this paper is to present a preliminary experience on the laparoscopic Roux-en-Y gastrojejunal bypass, associated with Nissen fundoplication and gastrostomy, to treat and prevent GER in NIC with gastric emptying disorders. Eight neurologically impaired children underwent surgical treatment because of feeding problems and pulmonary complications. The procedure included: 1) hiatoplasty, 2) Nissen fundoplication, 3) 20-cm Roux-en-Y gastrojejunal anastomosis and jejuno-jejunal anastomosis, and 4) gastrostomy. All cases were fed on postoperative day 3 without any intraoperative complications. One case developed an obstruction of the distal anastomosis due to adhesion and needed reoperation. Outcome was clinically evaluated with serial upper gastrointestinal contrast studies and endoscopies. Laparoscopic proximal Roux-en-Y gastrojejunal diversion, without gastric resection, is a safe, feasible procedure that improves gastric emptying and reduces the risk of GER recurrence. Yet, long-term results still have to be evaluated.

Omega loop gastric bypass is a successful bariatric surgery with numerous favorable circumstances as being basic, effective on weight reduction and treatment of obesity associated metabolic disorder, the short expectation to learn and adapt, and the simplicity of correction and inversion. However, there are arguments about the possibility of biliary reflux and/or the potential danger of gastroesophageal malignancy after the procedure. Fifty patients experiencing morbid obesity with body mass index >40 or >35 kg/m 2 with two related comorbidities, for example, diabetes type II, hypertension, or dyslipidemia, underwent omega loop gastric bypass with a follow-up period up to 18 months, investigating for any symptom of reflux infection by upper gastrointestinal tract endoscopy and pH metry. Reflux esophagitis (a gastroesophageal reflux disease) was detected in 3 patients (6%); 2 cases (4%) showed (Grade A) acidic reflux esophagitis at 6 and 12 months postoperatively. Just 1 case (2%) had experienced gastroesophageal biliary reflux esophagitis (Grade A) at 12 months. No metaplasia or dysplasia was detected in the endoscopic biopsies. Omega loop gastric bypass is a safe and effective bariatric procedure with low incidence of postoperative biliary reflux, metaplasia, or dysplasia at the esophagogastric junction, confirmed 18 months after the operation.

Extramedullary plasmacytoma is a plasma cell neoplasm that presents as a solitary lesion in soft tissue. Most extramedullary plasmacytomas involve the nasopharynx or upper respiratory tract. Primary plasmacytoma of the stomach is extremely rare. A 78-year-old Korean woman presented with epigastric pain for 3 months. She had a history of an intractable gastric ulcer despite repeated endoscopic biopsies and appropriate medical therapy for the ulcer. She underwent another endoscopy and a biopsy was performed for multiple large and deep specimens. Ultimately, primary gastric plasmacytoma was confirmed. However, she and her attendant refused standard local radiotherapy or surgical resection. She came to our emergency room 3 months later with hematemesis due to a large gastric ulcer, despite management with medication for over 3 months at a local clinic. We again recommended local radiation or surgical resection. However, as she was willing to undergo only medical therapy, she was prescribed high-dose dexamethasone. Surprisingly, her ulcer completely regressed and remission was maintained for over 1 year. We report successful treatment of a rare primary gastric plasmacytoma mimicking intractable ulcer by using high-dose dexamethasone. To the best of our knowledge, this is the first reported case successfully treated with only high-dose dexamethasone.

Sixty-eight patients with various types of gastritis, 23 patients with normal stomachs, and four patients with other gastric diseases were examined in a prospective study to assess the sensitivity and specificity of single-contrast (SC) and double-contrast (DC) upper gastrointestinal examinations in the evaluation of gastritis. All patients underwent endoscopy with biopsy followed first by DC and then by SC radiography. The respective sensitivities of SC and DC radiography were 58% and 72% for all examinations and 59% and 77% for adequate examinations only. The respective specificities were 59% and 55% based on all examinations. Useful radiographic features included polypoid defectsmore » and erosions detected by both methods, abnormal folds and flattened margins detected by the SC technique, and narrowed lumen and crenulated margins detected by the DC technique. In 93% of all cases, the correct diagnosis was based on two or more of these radiographic features. According to this study, the radiographic sensitivity in the detection of gastritis is reliable only in cases of moderate-to-severe disease and only when based on findings of the DC examination. Neither SC nor DC radiography should be used as the primary screening method for patients with suspected gastritis, and the radiographic diagnosis should be restricted to the terms ''erosive'' or ''nonerosive gastritis.''« less

Objectives: To observe the effects of both propofol/alfentanil and propofol/ketamine on sedation during upper gastrointestinal system endoscopy in morbidly obese patients (UGSEMOP). Methods: In a prospective, double-blinded, randomized clinical study, 52 patients scheduled for UGSEMOP were assigned to either group A (n=26; 10 µg/kg intravenous [IV] alfentanil) or group K (n=26; 0.5 mg/kg IV ketamine). Each patient was administered 0.7 mg/kg propofol for induction. If it was needed, the patients were administered an additional dose of IV propofol. This study was performed in Sehitkamil State Hospital, Gaziantep, Turkey, between January 2014-2015. Total propofol consumption, time to achieve Modified Aldrete Scores (MAS) of 5 and 10 following the procedure, physician and patient satisfaction scores, and instances of side effects, such as bradycardia and hypotension were recorded. Results: Time to onset of sedation and duration of sedation were both significantly shorter in group A. Patients in group A also required less time to achieve an MAS of 5. Total propofol consumption was significantly lower in group A. Conclusion: Both propofol/alfentanil and propofol/ketamine combinations provided appropriate hypnosis and analgesia during UGSEMOP. However, propofol consumption was significantly higher using the propofol/ketamine combination. PMID:27761556

A lactose breath test (LBT) is usually used to diagnose lactase deficiency, and a lactose quick test (LQT) has been proposed as a new test on duodenal biopsies to detect this disorder. We aimed to assess the diagnostic accuracy of LBT and LQT and their ability to predict the clinical response to a lactose-free diet in patients with self-reported lactose intolerance. Fifty-five patients (age 47 ± 14 y; M/F 15/36) underwent upper gastrointestinal endoscopy and 25g-LBT. Two duodenal biopsies were taken to determine lactase deficiency (normal, mild, or severe) by LQT and to rule out other causes of secondary lactose malabsorption. Patients with a positive LBT and normal LQT also underwent a glucose breath test to exclude small intestinal bacterial overgrowth as a cause of the former result. The severity of gastrointestinal symptoms was measured with a GSS questionnaire, under basal condition and 1 month after a lactose-free diet. Lactose malabsorption was detected in 31/51 patients with LBT and in 37/51 patients with LQT (P = NS). Celiac disease was found in 2 patients. Two LBT+ patients showed a positive glucose breath test for small intestinal bacterial overgrowth. Eight patients had a mild hypolactasia by LQT and a negative LBT, but they had a significant improvement of symptoms after diet. LQT and LBT were concordant in 83% of cases and predicted the response to a lactose-free diet in 98% and 81% of the cases, respectively (P = 0.03). LQT is as sensitive as LBT in detecting lactase deficiency; however, it seems to be more accurate than LBT in predicting the clinical response to a lactose-free diet.

AIM: To investigate gastrointestinal complications associated with non-steroidal anti-inflammatory drug (NSAIDs) use in children. METHODS: A retrospective, multicenter study was conducted between January 2005 and January 2013, with the participation of 8 Italian pediatric gastroenterology centers. We collected all the cases of patients who refer to emergency room for suspected gastrointestinal bleeding following NSAIDs consumption, and underwent endoscopic evaluation. Previous medical history, associated risk factors, symptoms and signs at presentation, diagnostic procedures, severity of bleeding and management of gastrointestinal bleeding were collected. In addition, data regarding type of drug used, indication, dose, duration of treatment and prescriber (physician or self-medication) were examined. RESULTS: Fifty-one patients, including 34 males, were enrolled (median age: 7.8 years). Ibuprofen was the most used NSAID [35/51 patients (68.6%)]. Pain was the most frequent indication for NSAIDs use [29/51 patients (56.9%)]. Seven patients had positive family history of Helicobacter pylori (H. pylori) infection or peptic ulcer, and 12 had associated comorbidities. Twenty-four (47%) out of 51 patients used medication inappropriately. Hematemesis was the most frequent symptom (33.3%). Upper gastrointestinal endoscopy revealed gastric lesions in 32/51 (62%) patients, duodenal lesions in 17 (33%) and esophageal lesions in 8 (15%). In 10/51 (19.6%) patients, a diagnosis of H. pylori gastritis was made. Forty-eight (94%) patients underwent medical therapy, with spontaneous bleeding resolution, while in 3/51 (6%) patients, an endoscopic hemostasis was needed. CONCLUSION: The data collected in this study confirms that adverse events with the involvement of the gastrointestinal tract secondary to NSAID use are also common in children PMID:26855547

There is a bidirectional relationship between gastroesophageal reflux disease (GERD) and sleep. It has been demonstrated that antireflux treatment can improve sleep quality in GERD patients with nighttime reflux. Patients with heartburn and/or regurgitation ≥3 times/week and insomnia for ≥3 months were included. Patients were assessed at baseline with the demographic, GERD symptom assessment scale, Epworth sleepiness scale, Berlin sleep apnea, Pittsburgh sleep quality index, and the Insomnia severity index questionnaires. Subjects underwent an upper endoscopy followed by pH testing. Subsequently, subjects were randomized, in a double-blind, placebo-controlled trial, to receive either ramelteon 8 mg or placebo before bedtime for 4 weeks. During the last week of treatment, subjects completed a daily GERD symptom and sleep diary and underwent actigraphy. Sixteen patients completed the study, 8 in each arm (mean age and M/F were 48.5 vs. 57.8 y, and 8/0 vs. 6/2, respectively). Patients who received ramelteon demonstrated a statistically significant decrease in symptom score as compared with those who received placebo for daytime heartburn (-42% vs. -29%), nighttime heartburn (-42% vs. 78%), 24-hour heartburn (-42% vs. -3%), and 24-hour acid regurgitation (-26% vs. 19%) (all P<0.05). Insomnia severity index score was significantly reduced in patients receiving ramelteon as compared with placebo (-46% vs. -5%, P<0.05). Ramelteon group also demonstrated a significant improvement in sleep efficiency and sleep latency, as compared with placebo, P<0.05). No significant adverse events were observed with ramelteon. Ramelteon significantly improved symptoms in patients with GERD. In addition, ramelteon significantly improved patients' sleep experience. Further studies are needed in the future (NCT01128582).

We sought to compare intercellular space diameter in children with non-erosive and erosive reflux disease, and a control group. We also aimed to characterize the reflux pattern in erosive and non-erosive reflux disease patients, and to explore the relationship between intercellular space diameter values and reflux parameters. Twenty-four children with non-erosive reflux disease, 20 with erosive reflux disease, and 10 controls were prospectively studied. All patients and controls underwent upper endoscopy. Biopsies were taken at 2-3 cm above the Z-line, and intercellular space diameter was measured using transmission electron microscopy. Non-erosive and erosive reflux disease patients underwent impedance-pH monitoring. Mean intercellular space diameter values were significantly higher in both non-erosive (0.9 ± 0.2 μm) and erosive reflux disease (1 ± 0.2 μm) compared to controls (0.5 ± 0.2 μm, p<0.01). No difference was found between the two patient groups. Acid exposure time, the number of acid, weakly acidic and weakly alkaline reflux events did not differ between the two patient groups. No difference was found in the mean intercellular space diameter between non-erosive reflux disease children with and without abnormal acid exposure time (1 ± 0.3 vs. 0.9 ± 0.2 μm). No correlation was found between any reflux parameter and intercellular space diameter values. Dilated intercellular space diameter seems to be a useful and objective marker of oesophageal damage in paediatric gastro-oesophageal reflux disease, regardless of acid exposure. In childhood, different gastro-oesophageal reflux disease phenotypes cannot be discriminated on the basis of reflux pattern. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l.

AIM: To assess the necessity of esophagogastroduodenoscopy (EGD) to predict the outcome of caustic ingestion in children. METHODS: The study included 206 children who underwent EGD because of ingestion of caustic substances between January 2005 and August 2010. Retrospective analysis of data of the patients was performed. RESULTS: The male/female ratio was 1.6 and mean age was 38.1 ± 28.8 mo. The caustic substances were acidic in 72 (34.9%) cases, alkaline in 56 (27.2%), liquid household bleach in 62 (30.1%), and unknown in 16 (7.8%). Fifty-seven (27.7%) patients were symptom-free. Significant clinical findings were observed in 149 (72.3%) patients. Upper gastrointestinal endoscopy findings of esophageal injury were grade 0 in 86 (41.7%) patients, grade 1 in 49 (23.8%), grade 2a in 42 (20.4%), grade 2b in 28 (13.6%), and grade 3a in 1 (0.5%) patient. 35 patients with grade 2a, 2b, and 3a injuries underwent esophageal dilation at second week of ingestion. Esophageal stricture, which necessitated a regular dilation program developed in 13 of the aforementioned 35 patients. There is no statistically significant difference in the rate of development of esophageal stricture between the patients who ingested acidic (15.3%) and alkaline (8.9%) substances (P = 0.32). Severe gastric injury was detected in 38 (18.5%) patients. The rate of development of gastric injury was significantly higher in the acidic group (14%) than in the alkaline group (2.9%) (P = 0.001). Out of 149 patients with clinical findings, 49 (32.9%) patients had no esophageal injury and 117 (78.5%) patients had no gastric lesion. Esophageal and severe gastric injuries were detected in 20 (35.1%) and 8 (14%) of patients with no clinical findings respectively. Pyloric stenosis developed in 6 patients. Pyloric obstruction improved with balloon dilation in 2 patients. Mean hospitalization time were 1.2 ± 0.5 d for grade 0 and 2.3 ± 5 d for grade 1 and 6.3 ± 6.2 d for grade 2a and 15.8 ± 18.6 d for grade 2b. It was significantly longer for patients with grade 2a and 2b injuries (P = 0.000). CONCLUSION: Endoscopy is an effective technique for determining the presence of esophageal and gastric damage and to avoid unnecessary treatment in patients with no or mild injury. PMID:22416185

Portal hypertension is a common pathology in childhood and one of its most common causes is cavernomatosis of the portal vein. This obstruction causes hemodynamic changes which lead to splenomegaly and collateral circulation. Esophageal varices are one of the most important sequelae, which endanger the patient's life because of a bleeding tendency. Ecosonography helps to detect the thickening of the lesser omentum vis a vis the aortic diameter, caused by the collateral circulation. We studied 15 children presenting with portal hypertension resulting from portal vein cavernomatosis; we performed an upper GI endoscopy and abdominal ecosonography. The endoscopy revealed grade II esophageal varices in 20% of cases, the remaining 80% had grade III and grade IV. Ecosonography revealed an increased lesser omentum/aorta ratio in children with portal hypertension, compared to controls (p < 0.001). Our results suggest that the lesser omentum/aorta ratio has diagnostic value in pediatric portal hypertension.

Heterotopic gastric mucosa (HGM) of the esophagus is a congenital anomaly consisting of ectopic gastric mucosa. It may be connected with disorders of the upper gastrointestinal tract, exacerbated by Helicobacter pylori. The diagnosis of HGM is confirmed via endoscopy with biopsy. Histopathology provides the definitive diagnosis by demonstrating gastric mucosa adjacent to normal esophageal mucosa. HGM located in the distal esophagus needs differentiation from Barrett's esophagus. Barrett's esophagus is a well-known premalignant injury for adenocarcinoma of the esophagus. Malignant progression of HGM occurs in a stepwise pattern, following the metaplasia-dysplasia-adenocarcinoma sequence.We present a rare case of a teenage girl with HGM located in the distal esophagus, associated with chronic gastritis and biliary duodenogastric reflux. Endoscopy combined with biopsies is a mandatory method in clinical evaluation of metaplastic and nonmetaplastic changes within HGM of the esophagus.

Esophagogastroduodenoscopy (EGD) is a commonly used, safe diagnostic modality for evaluation of epigastric pain and rarely its major complications include perforation, haemorrhage, dysrhythmias and death. Gastric volvulus has been reported to complicate percutaneous endoscopic gastrostomy but its occurrence after diagnostic EGD has not yet been reported in literature. The successful management relies on prompt diagnosis and gastric untwisting, decompression and gastropexy or gastrectomy in full thickness necrosis of the stomach wall. A 38-year-old woman presented with epigastric pain and EGD showed pangastritis. Immediately after EGD she developed increased severity of pain, vomiting and abdominal distension. Emergency laparotomy carried out for peritoneal signs revealed eventration of left hemidiaphragm with the stomach twisted anticlockwise in the longitudinal axis. After gastric decompression and untwisting of volvulus, anterior gastropexy and gastrostomy was carried out. Hence, we report this rare complication of diagnostic endoscopy and review the existing literature on the management.

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

Reflux Hypersensitivity: A New Functional Esophageal Disorder.

PubMed

Yamasaki, Takahisa; Fass, Ronnie

2017-10-30

Reflux hypersensitivity, recently introduced by Rome IV as a new functional esophageal disorder, is currently considered as the presence of typical heartburn symptoms in patients with normal upper endoscopy and esophageal biopsies, normal esophageal pH test and with evidence of a close correlation between patients' heartburn and reflux events. Reflux hypersensitivity is very common and together with functional heartburn accounts for more than 90% of the heartburn patients who failed treatment with proton pump inhibitor twice daily. In addition, reflux hypersensitivity affects primarily young to middle aged women, commonly overlaps with another functional gastrointestinal disorders, and is often associated with some type of psychological comorbidity. Diagnosis is made by using endoscopy with esophageal biopsies, pH-impedance, and high-resolution esophageal manometry. Reflux hypersensitivity is primarily treated with esophageal neuromodulators, such as tricyclic anti-depressants and selective serotonin reuptake inhibitors among others. Surgical anti-reflux management may also play an important role in the treatment of reflux hypersensitivity.

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.

Upper digestive endoscopy with biopsy and histopathological evaluation of the biopsy material is the standard method for diagnosing gastric cancer (GC). However, this procedure may not be widely available for screening in the developing world, whereas in developed countries endoscopy is frequently used without major clinical gain. There is a high demand for a simple and non-invasive test for selecting the individuals at increased risk that should undergo the endoscopic examination. Here, we studied the feasibility of a nanomaterial-based breath test for identifying GC among patients with gastric complaints. Alveolar exhaled breath samples from 130 patients with gastric complaints (37 GC/32 ulcers / 61 less severe conditions) that underwent endoscopy/biopsy were analyzed using nanomaterial-based sensors. Predictive models were built employing discriminant factor analysis (DFA) pattern recognition, and their stability against possible confounding factors (alcohol/tobacco consumption; Helicobacter pylori) was tested. Classification success was determined (i) using leave-one-out cross-validation and (ii) by randomly blinding 25% of the samples as a validation set. Complementary chemical analysis of the breath samples was performed using gas chromatography coupled with mass spectrometry. Three DFA models were developed that achieved excellent discrimination between the subpopulations: (i) GC vs benign gastric conditions, among all the patients (89% sensitivity; 90% specificity); (ii) early stage GC (I and II) vs late stage (III and IV), among GC patients (89% sensitivity; 94% specificity); and (iii) ulcer vs less severe, among benign conditions (84% sensitivity; 87% specificity). The models were insensitive against the tested confounding factors. Chemical analysis found that five volatile organic compounds (2-propenenitrile, 2-butoxy-ethanol, furfural, 6-methyl-5-hepten-2-one and isoprene) were significantly elevated in patients with GC and/or peptic ulcer, as compared with less severe gastric conditions. The concentrations both in the room air and in the breath samples were in the single p.p.b.v range, except in the case of isoprene. The preliminary results of this pilot study could open a new and promising avenue to diagnose GC and distinguish it from other gastric diseases. It should be noted that the applied methods are complementary and the potential marker compounds identified by gas-chromatography/mass spectrometry are not necessarily responsible for the differences in the sensor responses. Although this pilot study does not allow drawing far-reaching conclusions, the encouraging preliminary results presented here have initiated a large multicentre clinical trial to confirm the observed patterns for GC and benign gastric conditions.

Ultrathin endoscopy (UTE) is an acceptable and cost-effective alternative to EGD with the patient under sedation, although the diagnostic accuracy of UTE is not well established. To compare the diagnostic accuracy of UTE and high-resolution endoscopy (HRE) for superficial gastric neoplasia. Prospective comparative study. Academic center. Patients with or without superficial gastric neoplasia underwent peroral UTE and HRE, back-to-back in a random order while under standard sedation. The procedures were performed by 2 endoscopists who were blinded to the clinical information. The rate of missed lesions and misdiagnosis, sensitivity, and specificity for the diagnosis of gastric neoplasia when using pathology as the reference standard. In total, 126 lesions (41 superficial gastric neoplasias, 85 nonneoplastic lesions) were recorded in 57 enrolled patients. For the diagnosis of gastric neoplasia, the sensitivity of UTE (58.5%) was significantly (P = .021) lower than that of HRE (78%), and the specificity of UTE (91.8%) was significantly (P = .014) lower than that of HRE (100%). The rate of missed lesions and misdiagnosis of gastric neoplasias when using UTE (41.5%) was significantly (P > .001) higher than that of HRE (22.0%). The corresponding rate of neoplasias at the proximal portion (fornix and corpus) when using UTE (29%) was significantly (P = .002) higher than that of HRE (7.2%), although the rates of neoplasias at the distal portion (angulus and antrum) were comparable for UTE and HRE. Small sample numbers in an enriched population. The diagnostic accuracy of UTE is significantly lower than that of HRE for superficial gastric neoplasia, and this difference is particularly striking for neoplasias in the proximal stomach. For UTE to be used as an alternative modality, improvements in optical quality and the incorporation of additional procedures, including close-range observations and chromoendoscopy, are required to enhance visualization.

The European Position Paper on Rhinosinusitis and Nasal Polyps (EP3OS) incorporates symptomatic, endoscopic, and radiologic criteria in the clinical diagnosis of chronic rhinosinusitis (CRS), while in epidemiological studies, the definition is based on symptoms only. We aimed to assess the reliability and validity of a symptom-based definition of CRS using data from the GA(2) LEN European survey. On two separate occasions, 1700 subjects from 11 centers provided information on symptoms of CRS, allergic rhinitis, and asthma. CRS was defined by the epidemiological EP3OS symptom criteria. The difference in prevalence of CRS between two study points, the standardized absolute repeatability, and the chance-corrected repeatability (kappa) were determined. In two centers, 342 participants underwent nasal endoscopy. The association of symptom-based CRS with endoscopy and self-reported doctor-diagnosed CRS was assessed. There was a decrease in prevalence of CRS between the two study phases, and this was consistent across all centers (-3.0%, 95% CI: -5.0 to -1.0%, I(2) = 0). There was fair to moderate agreement between the two occasions (kappa = 39.6). Symptom-based CRS was significantly associated with positive endoscopy in nonallergic subjects, and with self-reported doctor-diagnosed CRS in all subjects, irrespective of the presence of allergic rhinitis. Our findings suggest that a symptom-based definition of CRS, according to the epidemiological part of the EP3OS criteria, has a moderate reliability over time, is stable between study centers, is not influenced by the presence of allergic rhinitis, and is suitable for the assessment of geographic variation in prevalence of CRS. © 2010 John Wiley & Sons A/S.

The treatment of peptic ulcer bleeding (PUB) is complex, and mortality remains high. We present results from a nationwide initiative to monitor and improve the quality of care (QOC) in PUB. All Danish hospitals treating PUB patients between 2004 and 2011 prospectively registered demographic, clinical, and prognostic data. QOC was evaluated using eight process and outcome indicators, including time to initial endoscopy, hemostasis obtainment, proportion undergoing surgery, rebleeding risks, and 30-day mortality. A total of 13,498 PUB patients (median age 74 years) were included, of which one-quarter were in-hospital bleeders. Preadmission use of anticoagulants, multiple coexisting diseases, and the American Society of Anesthesiologists scores increased between 2004 and 2011. Considerable improvements were observed for most QOC indicators over time. Endoscopic treatment was successful with primary hemostasis achieved in more patients (94% in 2010-2011 vs. 89% in 2004-2006, relative risk (RR) 1.06 (95% confidence intervals 1.04-1.08)), endoscopy delay for hemodynamically unstable patients decreased during this period (43% vs. 34% had endoscopy within 6 h, RR 1.33 (1.10-1.61)), and fewer patients underwent open surgery (4% vs. 6%, RR 0.72 (0.59-0.87)). After controlling for time changes in prognostic factors, rebleeding rates improved (13% vs. 18%, adjusted RR 0.77 (0.66-0.91)). Crude 30-day mortality was unchanged (11% vs. 11%), whereas adjusted mortality decreased nonsignificantly over time (adjusted RR 0.89 (0.78-1.00)). QOC in PUB has improved substantially in Denmark, but the 30-day mortality remains high. Future initiatives to improve outcomes may include earlier endoscopy, having fully trained endoscopists on call, and increased focus on managing coexisting disease.

We investigated the incidence of gastrointestinal disorders requiring endoscopic and histopathologic diagnoses in renal transplant recipients. In this retrospective analysis, we examined records of patients seen at the Department of Hepato-Gastroenterology and Transplantation Sciences, Sindh Institute of Urology and Trans?lantation (Karachi, Pakistan) from January 2010 to December 2014. Renal transplant recipients with gastrointestinal disorders who required endoscopy, including proctoscopy and upper and lower gastrointestinal endoscopy as per indication, were included. Of 1770 patients included in this study, most were male patients (n = 1517; 85.7%). In this patient group, 1957 endoscopies, including proctoscopies, were performed, which included 1033 esophagogastroduodenoscopies (52.8%), 571 sigmoidoscopies (29.2%), and 107 colonoscopies (5.5%). The most common indications were diarrhea (n = 697; 31.2%) and weight loss (n = 690; 31%). Findings showed esophageal candidiasis in 127 patients (12%); however, biopsy revealed Candida species in 33 patients (34%). Cytomegalovirus and herpes esophagitis were observed in 8 (8.3%) and 5 patients (5.2%). Helicobacter pylori gastritis was seen in 119 patients (15.4%), cytomegalovirus gastritis in 9 patients (1.2%), and gastric lymphoma in 1 patient (0.1%). Duodenal fissuring was the most common pathology observed during endoscopy (396 patients; 33.9%), followed by decreased height of duodenal folds in 157 patients (13.4%), with biopsy showing sprue in 325 patients (37.6%) and giardiasis in 118 patients (13.7%). Lower gastrointestinal endoscopy showed ulcers in 198 patients (24.6%) and polyps in 31 patients (3.9%). Histopathologic examination showed cytomegalovirus colitis in 89 patients (15.5%), amebic colitis in 21 (3.7%), and tuberculosis in 11 (1.9%). We observed a wide spectrum of pathologic lesions, including opportunistic infections, in endoscopic biopsies from our renal transplant patients. Cytomegalovirus colitis was the most common infection in the lower gastrointestinal tract, whereas giardiasis was the most common in the duodenum.

Dyspepsia is defined as persistent or recurrent abdominal pain or discomfort centered in the upper abdomen. Dyspepsia represents up to 8.3% of all primary care physician visits and causes huge economic costs to patients and to the economy as a whole. The aim of this study was to measure the influence of dyspepsia on work productivity of people within the Brazilian workforce. Adult patients were enrolled if they met the Roma III criteria for uninvestigated dyspepsia. All patients answered a demographic questionnaire. Productivity impairment was measured by the Work Productivity and Activity Impairment questionnaire. Subjects underwent upper gastrointestinal endoscopy and were classified as having functional or organic dyspepsia. The study protocol was approved by the Ethics Committee of Hospital de Clínicas de Porto Alegre, Brazil. Eight hundred fifty patients with dyspepsia were evaluated: 628 were women (73.9%); mean age was 46.4 ± 12.9 years; 387 (45.5%) were active workers. Among active workers, 32.2% mentioned that dyspepsia had caused absenteeism from work during the preceding week and 78% reported a reduction of the work productivity (presenteeism). The lost work productivity score was 35.7% among all employed patients. The affect on work productivity was similar between patients with functional or organic dyspepsia. Our study showed an important influence of dyspepsia on work productivity. We did not find any statistically significant difference on the influence on work between patients with organic dyspepsia and functional dyspepsia. The social impact of these findings is underscored by taking into account the prevalence (up to 40%) of this condition in Brazil.

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.

Bleeding 'downhill' esophageal varices associated with benign superior vena cava obstruction: case report and literature review.

PubMed

Loudin, Michael; Anderson, Sharon; Schlansky, Barry

2016-10-24

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.

Prophylactic endotracheal intubation (PEI) is often advocated to mitigate the risk of cardiopulmonary adverse events in patients presenting with brisk upper GI bleeding (UGIB). However, the benefit of such a measure remains controversial. Our study aimed to compare the incidence of cardiopulmonary unplanned events between critically ill patients with brisk UGIB who underwent endotracheal intubation versus those who did not. Patients aged 18 years or older who presented at Cleveland Clinic between 2011 and 2014 with hematemesis and/or patients with melena with consequential hypovolemic shock were included. The primary outcome was a composite of several cardiopulmonary unplanned events (pneumonia, pulmonary edema, acute respiratory distress syndrome, persistent shock/hypotension after the procedure, arrhythmia, myocardial infarction, and cardiac arrest) occurring within 48 hours of the endoscopic procedure. Propensity score matching was used to match each patient 1:1 in variables that could influence the decision to intubate. These included Glasgow Blatchford Score, Charleston Comorbidity Index, and Acute Physiology and Chronic Health Evaluation scores. Two hundred patients were included in the final analysis. The baseline characteristics, comorbidity scores, and prognostic scores were similar between the 2 groups. The overall cardiopulmonary unplanned event rates were significantly higher in the intubated group compared with the nonintubated group (20% vs 6%, P = .008), which remained significant (P = .012) after adjusting for the presence of esophageal varices. PEI before an EGD for brisk UGIB in critically ill patients is associated with an increased risk of unplanned cardiopulmonary events. The benefits and risks of intubation should be carefully weighed when considering airway protection before an EGD in this group of patients.
