Calvopiña, Manuel; Flores, Jessica; Guaman, Isabel; Lara, Gabriela; Abarca, Jeyson
2017-10-01
For 11 years, a 38-year-old male residing in a subtropical region of Ecuador, was repeatedly diagnosed with chronic anemia, and treated with blood transfusions in a hospital of province of Cotopaxi, Ecuador. He was transferred to Quito for severe anemia, having hemoglobin of 4 g/dL. Duodenoscopy was performed and adult nematodes, identified later as Ancylostoma duodenale, were observed. The patient was successfully treated with albendazole for five consecutive days and given blood transfusions. In the control visit at eight months, without anemia and no hookworm ova in the stool examined were found.

Flexible Gastrointestinal Endoscopy in Ferrets (Mustela putorius furo).
Pignon, Charly; Huynh, Minh; Husnik, Roman; Jekl, Vladimir
2015-09-01
Gastrointestinal disease is a common complaint in ferrets (Mustela putorius furo). Their relatively simple and short gastrointestinal tract makes them good candidates for flexible endoscopy. However, apart from a few references in biomedical research articles, there is little information on the use of flexible endoscopy in ferrets. This review describes patient preparation, equipment, and select gastrointestinal endoscopy techniques in ferrets, including esophagoscopy, gastroscopy, duodenoscopy, percutaneous endoscopic gastrostomy, jejunoileoscopy, colonoscopy, and biopsy.

A Morgagni hernia was first described in 1761 by Giovanni Morgagni. In adults, it is accompanied by gastrointestinal- or respiratory-type symptoms. Herein, we report an 84-year-old woman presented to our hospital with nausea and vomiting. After hospitalization, an X-ray revealed a right diaphragmatic hernia. Based on the results of abdominal computed tomography, duodenoscopy, and upper gastrointestinography (gastrografin), we concluded that her symptoms were caused by Morgagni hernia. Our patient underwent laparoscopic surgery, and shortly thereafter, her symptoms resolved.

Keratinous inclusion cyst of oesophagus: unusual finding
Wan Abdul Rahman, Wan Faiziah; Mutum, Samarendra Singh; Fauzi, Mohd Hashairi
2013-01-01
Cysts of the oesophagus are unusual findings and they are classified according to the embryological site of origin. It may represent inclusion cysts, retention cysts and developmental cysts. We present a case of keratinous inclusion cyst of the lower oesophagus in a 71-year-old Malay woman who presented with dyspepsia and severe epigastric pain. An oesophago-gastro-duodenoscopy demonstrated a sliding hiatus hernia with whitish ulcer-like lesion at the lower oesophagus. Biopsy from the lesion revealed a keratinous inclusion cyst. The patient was given pantoprazole and put on regular follow-up for monitoring any other development. PMID:23878290

There are no prospective data regarding the risk of prosthetic joint infection following routine gastrointestinal endoscopic procedures. We wanted to determine the risk of prosthetic hip or knee infection following gastrointestinal endoscopic procedures in patients with joint arthroplasty. We conducted a prospective, single-center, case-control study at a single, tertiary-care referral center. Cases were defined as adult patients hospitalized for prosthetic joint infection of the hip or knee between December 1, 2001 and May 31, 2006. Controls were adult patients with hip or knee arthroplasties but without a diagnosis of joint infection, hospitalized during the same time period at the same orthopedic hospital. The main outcome measure was the odds ratio (OR) of prosthetic joint infection after gastrointestinal endoscopic procedures performed within 2 years before admission. 339 cases and 339 controls were included in the study. Of these, 70 cases (21%) cases and 82 controls (24%) had undergone a gastrointestinal endoscopic procedure in the preceding 2 years. Among gastrointestinal procedures that were assessed, esophago-gastro-duodenoscopy (EGD) with biopsy was associated with an increased risk of prosthetic joint infection (OR = 3, 95% CI: 1.1-7). In a multivariable analysis adjusting for sex, age, joint age, immunosuppression, BMI, presence of wound drain, prior arthroplasty, malignancy, ASA score, and prothrombin time, the OR for infection after EGD with biopsy was 4 (95% CI: 1.5-10). EGD with biopsy was associated with an increased risk of prosthetic joint infection in patients with hip or knee arthroplasties. This association will need to be confirmed in other epidemiological studies and adequately powered prospective clinical trials prior to recommending antibiotic prophylaxis in these patients.

ᅟ: Obesity is a global epidemic and will soon become the number one priority in healthcare management. Bariatric surgery causes a significant improvement in obesity and its related complications. Pre-operative esophago-gastro-duodenoscopy (EGD) is done by several bariatric surgical teams across the world but is still not mandatory. To study the percentage of symptomatic and asymptomatic pathological EGD findings in obese patients undergoing bariatric surgery and to analyze whether these findings influence the eventual choice of bariatric surgery. All patients posted for bariatric surgery at our institute from January 2015 to March 2017 had a pre-operative EGD done by the same team of endoscopists. In this study, totally, 675 patients were assessed prior to routine bariatric surgery. 78.52% of all pre-operative patients had an abnormal EGD. The most common endoscopic abnormalities found were hiatus hernia (52.44%), gastritis (46.22%), presence of Helicobacter (H.) pylori (46.67%), reflux esophagitis (16.89%), Barrett's esophagus (1.78%), gastric erosions (13.19%), and polyps (7.41%). Fifty patients had upper gastrointestinal polyps: 41 in the stomach, 3 in the esophagus, and 6 in the duodenum, mostly benign hyperplastic or inflammatory polyps. Two patients had gastrointestinal stromal tumor (GIST), 6 leiomyoma, and 6 neuroendocrine tumors (NET). Of those with endoscopic evidence of gastroesophageal reflux disease (GERD), 70 (60.03%) of patients were asymptomatic. The pre-operative EGD findings resulted in a change of the planned surgical procedure in 67 (9.93%) patients. Our study suggests that a large percentage of patients undergoing bariatric surgery have pathologically significant endoscopic findings of which a significant number are asymptomatic; this can lead to a change in the planned bariatric procedure in a section of patients; hence, we believe that EGD should be made mandatory as a pre-operative investigation in all bariatric surgery patients.

A woman in her 70s with Churg-Strauss syndrome presented with epigastric pain. She was being treated with steroids at the time of admission. Computed tomography showed swelling of the gallbladder, and percutaneous transhepatic cholangiography revealed bloody secretion. On duodenoscopy, bleeding was observed from the orifice of the major duodenal papilla. Emergency cholecystectomy was performed under a diagnosis of hemorrhagic cholecystitis;intraoperatively, extensive hematoma was detected in the thickened wall of the gallbladder. Subsequent histopathological examination revealed mucosal ulceration with infiltration of inflammatory cells, torn small vessels, and extensive transmural bleeding and abscess formation in the thickened wall of the gallbladder. We considered that the hemorrhagic cholecystitis was induced by either vasculitis or corticosteroid therapy. To the best of our knowledge, this is the first report of hemorrhagic cholecystitis associated with Churg-Strauss syndrome.

2007-01-01
The papilla of Vater emptying into the duodenal bulb site is extremely rare and considered an aberrant condition. We report here a case with recurrent duodenal ulcer bleeding associated with this anomaly. A 42-year-old man was admitted to St. Mary Hospital because of tarry stool for three days. Despite no documented etiology to explain recurrent ulceration, the patient had about ten episodes of ulcer bleeding since 1995. On duodenoscopy, 1.0 x 0.6 cm sized active stage duodenal ulcer with oozing was observed at the posterior wall side below the pylorus. The papilla of Vater was bulging just below the pylorus. Bile juice was excreted from its opening. Pancreatic duct and common bile duct, which drained into the bulb site, were observed on ERCP. In this report, we show that recurrent duodenal ulcer can be associated with the papilla of Vater just below the pylorus.

Gastrointestinal bleeding and obstructive jaundice: Think of hepatic artery aneurysm.
Vultaggio, Fabrice; Morère, Pierre-Henri; Constantin, Christophe; Christodoulou, Michel; Roulin, Didier
2016-06-27
Hemobilia is an uncommon and potential life-threatening condition mainly due to hepato-biliary tree traumatic or iatrogenic injuries. Spontaneously ruptured aneurysm of the hepatic artery is seldom described. We report the case of an 89-year-old woman presenting with abdominal pain, jaundice and gastrointestinal bleeding, whose ultrasound and computed tomography revealed a non-traumatic, spontaneous aneurysm of the right hepatic artery. The oeso-gastro-duodenoscopy and colonoscopy did not reveal any bleeding at the ampulla of Vater, nor anywhere else. Selective angiography confirmed the diagnosis of hepatic artery aneurysm and revealed a full hepatic artery originating from the superior mesenteric artery. The patient was successfully treated by selective embolization of microcoils. We discuss the etiologies of hemobilia and its treatment with selective embolization, which remains favored over surgical treatment. Although aneurysm of the hepatic artery is rare, especially without trauma, a high index of suspicion is needed in order to ensure appropriate treatment.

[Diagnosis of carcinoma of Vater's ampulla by duodenoscopy].
Ramírez-Degollado, J; García Bonilla, C; Aguirre García, J; Peniche Bojórquez, J
1977-01-01
Cancer of the ampula of Vater occurs in 10% of cases of jaundice caused by malignant neoplasms. Endoscopy with biopsy and citological study helps to establish the diagnosis in most instances, utilizing a duodeno fibroscope JFB-2. Fourteen patients, ten men and four women, were studied in a five year period in the Service of Endoscopy in the General Hospital of National Medical Center of the Mexican Institute of Social Security. All the patients presented with obstructive jaundice and only in four was papilary carcinoma suspected from the clinical and radiological studies. Direct biopsy was performed in all patients and brush biopsy for citology in 9. In all 14 patients a malignant lesion was observed macroscopically in the ampula of Vater projecting in to the duodenum. In thirteen of fourteen the lesion was diagnosed microscopically as adenocarcinoma and in eight of nine citologically. The utilization of this methodology facilitates the early diagnosis of the lesion in this way improves considerably the prognosis.

[Whipple's disease associated with opportunistic infections].
Meier-Willersen, H J; Maiwald, M; von Herbay, A
1993-06-11
A 36-year-old man, with a history of recurrent respiratory infection, dermatomycosis, arthralgia and abnormal stools for 12 years, developed a febrile illness (up to 40 degrees C). A Serratia marcescens septicaemia responded to antibiotics. Four months later cervical and abdominal lymph-adenopathies were noticed. Cervical lymph node biopsy revealed lymphadenitis with epithelioid cell nests. Duodenoscopy with biopsy demonstrated Whipple's disease associated with lambliasis. Electron-microscopy showed rod-shaped bacteria typical of Whipple's disease, and Giardia lamblia. Using the polymerase chain reaction, Whipple-specific DNA fragments of 284 base pairs from the genome of the Whipple bacterium (Tropheryma whippelii) were demonstrated. Antibiotic treatment with Ampicillin (2 g three times daily) and ceftriaxone (2 g once daily) i.v. for 21 days, followed by oral ofloxacin (200 mg daily) and co-trimoxazole (three times daily 800 mg sulfamethoxazole and 160 mg trimethoprim), brought about remission of Whipple's disease. Long-term antibiotic treatment was continued with co-trimoxazole. Lambliasis recurred after 3 and 5 months, despite treatment with metronidazole, 250 mg three times daily for 7 days.

[Midazolam as a premedication for gastroscopy].
Eisner, M
1984-04-01
Midazolam (Ro 21-3981; Dormicum ) is a new water-soluble benzodiazepine. Compared with diazepam and flunitrazepam, it has the advantage of a short half-life and good tolerability after intravenous administration. It induces light sleep 1/2 to 2 min after injection, and anterograde amnesia. It has minimal hemodynamic and respiratory effects. We administered midazolam by intravenous injection in a dose of 3-7 mg to 100 patients about to undergo esophago-, gastro-, or duodenoscopy. The patient became quiet and relaxed, falling into a light sleep but remaining capable of following simple instructions. After completion of the endoscopy, the patients were half awake, and listened attentively to the report. They subsequently usually slept for 1-2 h, afterwards remembering nothing of the procedure. Two (at most, 3) hours after injection, the patients were again completely awake and able to go home or back to work. In some cases, concentration was slightly impaired for the rest of the day. Compared with other premedications , midazolam is better suited for use in endoscopy, owing to its rapid onset and short duration of action.

The treatment of iron-deficiency anemia with oral iron supplements can present side-effects on the GI tract mucosa including necrosis, ulceration, or ischemia. The particular endoscopic findings and the histopathological exam will establish the diagnosis of erosive gastritis with iron deposits in the gastric mucosa. We present the case of a 14-year-old female admitted in our clinic for upper digestive hemorrhage, nausea, melena, and abdominal pain. Her personal history revealed iron deficiency anemia receiving oral iron supplements for approximately 2 weeks. The laboratory tests at the moment of admission pointed out anemia, increased level of serum iron, increased liver transaminases, a decreased level of ferritin, but with normal levels of both total iron-binding capacity and transferrin. The eso-gastro-duodenoscopy revealed multiple brown deposits on the surface of the gastric mucosa and multiple hemorrhagic lesions, under the aspect of erosions all over the gastric mucosa, but more severe in the antral part, and the histopathological exam confirmed the presence of iron deposits at this level. Iron-pill induced gastritis is a rare, under-diagnosed entity that can be present even at pediatric ages with potential severe clinical impact.

Presence of 25(OH)D deficiency and its effect on vitamin D receptor mRNA expression.
Goswami, R; Mondal, A M; Tomar, N; Ray, D; Chattopadhyay, P; Gupta, N; Sreenivas, V
2009-03-01
Vitamin D and its metabolites act through vitamin D receptor (VDR). We hypothesized that subjects with low serum 25(OH)D levels but normal PTH might have increased VDR expression. VDRmRNA expression was assessed by real time PCR in duodenal mucosa and PBMC (peripheral blood mononuclear cells) in 45 subjects with normal duodenoscopy and in PBMC alone in 48 healthy volunteers with hypovitaminosis D. 25(OH)D, PTH and VDRmRNA expression in PBMC was reassessed after 8 weeks of oral cholecalciferol (60 000 IU per week) in a subset (n=23) of healthy volunteers. The VDRmRNA expressions in the duodenum and PBMC were significantly correlated (r=0.42), but the expression was 13 times higher in the former than the latter. The mean VDRmRNA expression was similar in 25(OH)D-deficient subjects with or without PTH elevation, both in the duodenum and PBMC. The PBMC VDRmRNA expression showed no significant change after cholecalciferol supplementation. A weak correlation coefficient between duodenal mucosa and PBMC VDRmRNA suggests that caution needs to be exercised while using the latter as a surrogate for other sites.

Helicobacter pylori infection in peptic ulcer disease: the importance of smoking and ethnicity.
Pillay, K V K; Htun, M; Naing, N N; Norsa'adah, B
2007-11-01
This study was conducted to determine the prevalence of Helicobacter pylori (H. pylori) and its associated factors among patients with peptic ulcer disease in Taiping Hospital. Consecutive peptic ulcer disease patients who had undergone esophagogastro-duodenoscopy were included. The H. pylori status was assessed by the rapid urease test. We excluded those who had active bleeding, a perforated peptic ulcer, severe vomiting, a history of gastric surgery, peptic ulcer disease or renal or liver diseases, carcinoma of the stomach, and recent use of antibiotics or proton pump inhibitors. Socio-demography, H. pylori status, medication history and other relevant clinical data were collected from case notes. A total of 416 subjects were selected, 49.7% were positive and 50.3% were negative for H. pylori infection. There were significant associations between H. pylori and age, ethnicity, smoking status and NSAID usage. However, there were no significant relationships between H. pylori status and gender or type of peptic ulcer. Multiple logistic regression showed that other ethnicities than Malays and smokers had a higher risk of H. pylori. Our prevalence rate was low and the identified risk factors were consistent with previous studies. Ethnic differences may be related to genetic and sociocultural behaviors. Quitting smoking may benefit peptic ulcer patients with H. pylori infection.

Venkatesh, Krishnappa; Cohen, Marta; Evans, Clair; Delaney, Peter; Thomas, Steven; Taylor, Christopher; Abou-Taleb, Ashraf; Kiesslich, Ralf; Thomson, Mike
2009-01-01
AIM: To evaluate the feasibility and utility of confocal laser endomicroscopy (CLE) in the description of normal gastrointestinal (GI) mucosa and in the diagnosis of GI disorders in children, in comparison to histology. METHODS: Forty-four patients (19 female) median age 10.9 years (range 0.7-16.6 years) with suspected or known GI pathology underwent esophago-gastro-duodenoscopy (OGD) (n = 36) and/or ileocolonoscopy (IC) (n = 31) with CLE using sodium fluorescein and acriflavine as contrast agents. Histological sections were compared with same site confocal images by two experienced pediatric and GI histopathologists and endoscopists, respectively. RESULTS: Duodenum and ileum were intubated in all but one patient undergoing OGD and IC. The median procedure time was 16.4 min (range 7-25 min) for OGD and 27.9 min (range 15-45 min) for IC. A total of 4798 confocal images were compared with 153 biopsies from the upper GI tract from 36 procedures, and 4661 confocal images were compared with 188 biopsies from the ileocolon from 31 procedures. Confocal images were comparable to conventional histology both in normal and in pathological conditions such as esophagitis, Helicobacter pylori gastritis, celiac disease, inflammatory bowel disease, colonic heterotopia, and graft versus host disease. CONCLUSION: CLE offers the prospect of targeting biopsies to abnormal mucosa, thereby increasing diagnostic yield, reducing the number of biopsies, decreasing the burden on the histopathological services, and reducing costs.

Gastric infection with Helicobacter pylori (Hp) can lead to chronic inactive gastritis, atrophy and intestinal metaplasia. To investigate in a cross-sectional study these changes among different socioeconomic and ethnic groups within the USA. We used the Miraca Life Sciences database, an electronic depository of clinicopathological records from patients distributed throughout the USA, to extract data from 487 587 patients who underwent oesophago-gastro-duodenoscopy with biopsy between 1/2008 and 12/2014. We then classified patients into ethnic and socioeconomic categories using previously validated algorithms, as well as ZIP code-based information derived from the 2011-2012 US Census. The prevalence of Hp increased significantly until the age-group 40-49, before it leveled off and started a gradual decrease. The prevalence of chronic inactive gastritis, atrophy, and intestinal metaplasia increased significantly with age. The prevalence of Hp, chronic inactive gastritis, intestinal metaplasia, and atrophy decreased significantly with the percentage of Whites per ZIP code. The prevalence of all four diagnoses also decreased significantly with rising levels of income or college education. Hp, chronic inactive gastritis, atrophy and intestinal metaplasia were more common among Hispanics and the influence of income or college education less pronounced than in the entire population. Hp, chronic inactive gastritis, atrophy, and intestinal metaplasia were also more common among East-Asians, Hp and atrophy decreasing with rising income but remaining unaffected by levels of college education. Ethnicity and socioeconomic factors influence the occurrence of Hp gastritis, and its progression to chronic inactive gastritis, atrophy or intestinal metaplasia. © 2017 John Wiley & Sons Ltd.

To combine community and hospital services in order to enable improvements in patient management, an integrated gastroenterology service (IGS) was established. Referral patterns to specialist clinics were optimized; open access route for endoscopic procedures (including esophago-gastro-duodenoscopy, sigmoidoscopy and colonoscopy) was established; family physicians' knowledge and confidence were enhanced; direct communication lines between experts and primary care physicians were opened. Continuing education, guidelines and agreed instructions for referral were promoted by the IGS. Six quality indicators were developed by the Delphi method, rigorously designed and regularly monitored. Improvement was assessed by comparing 2010, 2011 and 2012 indicators. An integrated delivery system in a specific medical field may provide a solution to a fragmented healthcare system impaired by a lack of coordination. In this paper we describe a new integrated gastroenterology service established in April 2010. Waiting time for procedures decreased: 3 mo in April 30th 2010 to 3 wk in April 30th 2011 and stayed between 1-3 wk till December 30th 2012. Average cost for patient's visit decreased from 691 to 638 NIS (a decrease of 7.6%). Six health indicators were improved significantly comparing 2010 to 2012, 2.5% to 67.5%: Bone densitometry for patients with inflammatory bowel disease, preventive medications for high risk patients on aspirin/NSAIDs, colonoscopy following positive fecal occult blood test, gastroscopy in Barrett's esophagus, documentation of family history of colorectal cancer, and colonoscopy in patients with a family history of colorectal cancer. Establishment of an IGS was found to effectively improve quality of care, while being cost-effective.

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.

The aim of this study was to determine the number of OGDs (oesophago-gastro-duodenoscopies) trainees need to perform to acquire competency in terms of successful unassisted completion to the second part of the duodenum 95% of the time. OGD data were retrieved from the trainee e-portfolio developed by the Joint Advisory Group on GI Endoscopy (JAG) in the UK. All trainees were included unless they were known to have a baseline experience of >20 procedures or had submitted data for <20 procedures. The primary outcome measure was OGD completion, defined as passage of the endoscope to the second part of the duodenum without physical assistance. The number of OGDs required to achieve a 95% completion rate was calculated by the moving average method and learning curve cumulative summation (LC-Cusum) analysis. To determine which factors were independently associated with OGD completion, a mixed effects logistic regression model was constructed with OGD completion as the outcome variable. Data were analysed for 1255 trainees over 288 centres, representing 243 555 OGDs. By moving average method, trainees attained a 95% completion rate at 187 procedures. By LC-Cusum analysis, after 200 procedures, >90% trainees had attained a 95% completion rate. Total number of OGDs performed, trainee age and experience in lower GI endoscopy were factors independently associated with OGD completion. There are limited published data on the OGD learning curve. This is the largest study to date analysing the learning curve for competency acquisition. The JAG competency requirement for 200 procedures appears appropriate.

Histomorphological Spectrum of Duodenal Pathology in Functional Dyspepsia Patients
Rane, Sharada Raju; Jadhav, Meenal Vitthal
2017-01-01
Introduction Functional Dyspepsia (FD) is one of the most common causes of gastrointestinal symptoms aetiology of which is poorly understood. Aim To study duodenal histomorphological features and their relationship with Helicobacter pylori (H Pylori) infection in patients of FD. Materials and Methods This case control study included 50 cases of FD patients selected according to Rome III criteria and 30 age and sex matched controls. These were subjected to oesophago-gastro-duodenoscopy, rapid urease test for detection of H. pylori on gastric antral biopsy and duodenal biopsy from second part of duodenum for histopathological evaluation by light microscopy. Ten antral urease positive cases of FD with highest Intraepithelial Lymphocyte Count (IEL) were subjected to Immunohistochemistry (IHC). Results Duodenal inflammation was an invariable feature noted in FD. Morphological spectrum consisted of increased IEL in 72%, increased duodenal eosinophils in 92%, presence of focal villous atrophy in 16%, lymphoid aggregates, colonic metaplasia, and duodenal H. pylori infection in 4% each. Gastric H. pylori positivity was noted in 48% cases of FD. Increased duodenal IEL count and duodenal eosinophilia was noted in 75%, 87.5% such cases. Same was noted respectively, with 61.5% and 95.15% cases with gastric H. pylori negativity. In cases of FD, duodenal IEL and eosinophil count in lamina propria showed statistically significant rise when compared with control and had positive correlation with gastric H pylori infection. On IHC, increased expression of CD 8 was noted in duodenal IEL and lymphocytes in lamina propria as compared to CD4. Conclusion Our study provided some insight in pathogenesis of FD and role of H. pylori in its aetiology. PMID:28764169

Currently, no standard approach exists to the level of monitoring or presence of staff with anaesthetic expertise required during emergency esophago-gastro-duodenoscopy (EGD) for peptic ulcer bleeding (PUB). We assess the association between anaesthesia care and mortality. We further describe the prevalence and inter-hospital variation of anaesthesia care in Denmark and identify clinical predictors for choosing anaesthesia care. This population-based cohort study included all emergency EGDs for PUB in adults during 2012-2013. About 90-day all-cause mortality after EGD was estimated by crude and adjusted logistic regression. Clinical predictors of anaesthesia care were identified in another logistic regression model. Some 3.056 EGDs performed at 21 hospitals were included; 2074 (68%) received anaesthesia care and 982 (32%) were managed under supervison of the endoscopist. Some 16.7% of the patients undergoing EGD with anaesthesia care died within 90 days after the procedure, compared to 9.8% of the patients who had no anaesthesia care, adjusted OR = 1.51 (95% CI = 1.25-1.83). Comparing the two hospitals with the most frequent (98.6% of al EGDs) and least frequent (6.9%) use of anaesthesia care, mortality was 13.7% and 11.7%, respectively, adjusted OR = 1.22 (95% CI = 0.55-2.71). The prevalence of anaesthesia care varied between the hospitals, median = 78.9% (range 6.9-98.6%). Predictors of choosing anaesthesia care were shock at admission, high ASA score, and no pre-existing comorbidity. Use of anaesthesia care for emergency EGD was associated with increased mortality, most likely because of confounding by indication. The use of anaesthesia care varied greatly between hospitals, but was unrelated to mortality at hospital level.

Gastroesophageal reflux disease (GERD) is clinically-identified in patients with systemic sclerosis (SSc). The GERD-questionnaire (GERD-Q) score is a sensitive, non-invasive, diagnostic screening tool for diagnosis of GERD in general patients, but it has been not investigated for use in SSc. Our aim was to evaluate the proper cut-off GERD-Q score, sensitivity and specificity for a diagnosis of GERD in SSc patients. A cross-sectional study using the GERD-Q was performed during May 2012-January 2013 on patients over 18 with the diffuse SSc subset. Both esophago-gastro-duodenoscopy (EGD) and 24-hr pH-monitoring (24hr-pH) were performed as the gold standard tests for both symptomatic and asymptomatic GERD. A total of 75 SSc patients completed the GERD-Q, EGD and 24hr-pH. We identified 22 males (29.3%), 53 females (70.7%) with a mean age of 54.2 years. The respective number of symptomatic and asymptomatic GERD was 69 and 6 cases. For a GERD diagnosis, a cut-off GERD-Q score of 4 provided the best balance between sensitivity and specificity (96.9% and 50%, respectively). Of 48 participants (69.6%) with symptomatic GERD (i.e. positive for both EGD and 24hr-pH), 65 (94.2%) were positive for either EGD or 24hr-pH, and 4 (5.8%) were negative for both EGD and 24hr-pH. A respective majority (83%) vs. one-third of the asymptomatic group had reflux as detected by 24hr-pH vs. A GERD-Q score of 4 or higher indicates a high sensitivity for a diagnosis of GERD in SSc. It can thus be used as a non-invasive screening tool for diagnosing GERD in cases where EGD and 24hr-pH are unavailable.

Severity of chronic gastritis associated with Helicobacter pylori infection (CGAHpI) could play a role in evaluating the potential risk to develop gastric cancer. Our aim was to estimate the risk for gastric cancer in a clinical setting, according to histopathologic criteria, by applying the gastric cancer risk index (GCRI) METHODS: Histopathologic study of the gastric biopsies (corpus-antrum) from consecutive adult patients that underwent gastroesophageal duodenoscopy was carried out, and the GCRI was applied in patients presenting with CGAHpI. One hundred eleven patients (77% female) with a mean age of 38.6±13.1 years were included. Active Helicobacter pylori infection (aHpi) was diagnosed in 77 cases (69.40%). In 45% of the cases with aHpi, pangastritis (23%) or corpus-predominant gastritis (22%) was diagnosed. Nine cases were diagnosed with intestinal metaplasia (8%), 7 of which (77.70%) were in the aHpi group. Twenty one percent of the patients with aHpi had a GCRI of 2 (18.10%) or 3 (2.50%) points (high risk index), while 79.10% accumulated a GCRI of 0 or 1 points (low risk index). Of the patients with no aHpi, none of them had 3 points (p=0.001). Of the 18 patients that accumulated 2 or 3 points, 6 (33.30%) presented with intestinal metaplasia (all with pangastritis and corpus-predominant gastritis), of which 4 cases (66.60%) had aHpi. The estimated gastric cancer risk in patients with CGAHpI in the clinical setting studied was relatively low and 5% of the patients had a histopathologic phenotype associated with an elevated risk for developing gastric cancer.

Breast cancer resistance protein (BCRP) is an efflux transporter expressed in tissues that act as barriers to drug entry. Given that single nucleotide polymorphisms (SNPs) in the ABCG2 gene encoding BCRP are common, the possibility exists that these genetic variants may be a determinant of interindividual variability in drug response. The objective of this study is to confirm the human BCRP-mediated transport of sulfasalazine in vitro, evaluate interindividual variation in BCRP expression in human intestine and to determine the role of ABCG2 SNPs to drug disposition in healthy patients using sulfasalazine as a novel in vivo probe. To evaluate these objectives, pinch biopsies were obtained from 18 patients undergoing esophagogastro–duodenoscopy or colonoscopy for determination of BCRP expression in relation to genotype. Wild-type and variant BCRP were expressed in a heterologous expression system to evaluate the effect of SNPs on cell-surface trafficking. A total of 17 healthy individuals participated in a clinical investigation to determine the effect of BCRP SNPs on sulfasalazine pharmacokinetics. In vitro, the cell surface protein expression of the common BCRP 421 C>A variant was reduced in comparison with the wild-type control. Intestinal biopsy samples revealed that BCRP protein and mRNA expression did not significantly differ between patients with 34GG/421CC versus patients with 34GG/421CA genotypes. Remarkably, in subjects with 34GG/421CA genotype, sulfasalazine area under the concentration-time curve was 2.4-fold greater compared with 34GG/421CC subjects (P<0.05). This study links commonly occurring SNPs in BCRP with significantly increased oral sulfasalazine plasma exposure in humans. Accordingly, sulfasalazine may prove to have utility as in vivo probe for assessing the clinical impact of BCRP for the disposition and efficacy of drugs. PMID:18408567

To present our experience with the detection of bleeding in the small intestine by means of scintigraphy with in vivo-labelled red blood cells (RBCs) in the period of 1998-2009. A 12-year prospective study was accomplished with 40 patients (23 men, 17 women, aged 12-91, mean 56 years) who had lower gastrointestinal bleeding (obscure-overt bleeding) and underwent scintigraphy with in vivo-labelled RBCs by means of technetium 99m. The scintigraphy was usually performed after other diagnostic tests had failed to locate the bleeding. A total of 26 patients had a positive scintigraphy with in vivo-labelled RBCs and 14 patients had negative scintigraphy. The final diagnosis was confirmed in 20 of 26 patients with a positive scintigraphy by push enteroscopy (6/20), intraoperative enteroscopy (7/20), surgery (4/20), duodenoscopy (1/20), double-balloon enteroscopy (1/20) and X-ray angiography (1/20). The correct location of the bleeding site was identified by RBC scintigraphy in 15 of 20 (75%) patients with the confirmed source. The locations of the bleeding site identified by scintigraphy and enteroscopy (push, intraoperative) and surgical investigations were highly correlated in patients with a positive scintigraphy within the first 3 h. Eleven of the 20 correctly localized studies and none of the incorrectly localized studies were positive in the dynamic phase of imaging. In 5 patients (all erroneously localized), scintigraphy was positive only at a period longer than 18 h. RBC scintigraphy is an effective imaging modality in localizing lower gastrointestinal bleeding in patients for whom other diagnostic tests have failed to locate the bleeding. RBC scintigraphy can be successful in the detection of bleeding sites in the small intestine. Copyright © 2011 S. Karger AG, Basel.

The objective of this study was to evaluate the function of the minor duodenal papilla and to investigate the relationship between the history of acute pancreatitis and individual dorsal pancreatogram findings and the minor papilla function in pancreas divisum. Eight of the 21 patients with PD diagnosed by endoscopic retrograde cholangiopancreatography had a history of acute pancreatitis (group A), and 13 patients did not (group B). The reaction of pancreatic juice excreted via the minor papilla was evaluated after intravenous administration of secretin, by observing the repulsion of indigo carmine dye scattered on the surface of the minor papilla. The function of the minor papilla was classified into two types. In 12 patients, all of the pigment on the minor papilla was repelled within 5 min of secretin administration (type I), and in the remaining nine patients it was not (type II). After secretin administration, the pH of the minor papilla surface in type I was significantly higher than that in type II. There was no significant difference between the type I and type II patients in exocrine pancreatic function, as evaluated by a BT-PABA test. In the group A patients, the rate of occurrence of dorsal duct dilation (including changes of the terminal shape) was significantly greater than in the group B patients. The function of the minor papilla in the group A patients was significantly worse than in the group B patients. Outflow obstruction of pancreatic group B patients. Outflow obstruction of pancreatic juice, i.e., "relative stenosis of the minor papilla," was considered to be present in the patients with type II papilla, and, therefore, the patients with type II papilla might suffer from acute pancreatitis resulting from poor drainage of pancreatic juice and excessive pressure in the dorsal duct. The finding that patients with PD have one of two types of minor papilla will be useful for understanding the condition and selecting the therapeutic plan for individual patients.

Patients with idiopathic hypoparathyroidism (IH) require variable doses of calcium and 1-α-(OH)D. The reasons for such variability are not clear. As autoimmune mechanisms may play a role in IH, there is a possibility of coexistent coeliac disease with calcium/vitamin D malabsorption. We assessed the prevalence of coeliac disease and antitissue transglutaminase autoantibodies (anti-tTGAbs) in IH and analysed the effect of a gluten-free diet on calcaemic control. A total of 171 patients with IH and 126 healthy controls were screened for anti-tTGAb. IH patients with anti-tTGAb >20 RU/ml underwent duodenoscopy and intestinal biopsy; those with biopsy-proven coeliac disease were followed up on a gluten-free diet. Eleven of 171 (6·4%) patients with IH and seven of 126 (5·6%) controls had anti-tTGAb (P = 0·81). There was no difference in the clinical and biochemical parameters at diagnosis and during long-term follow-up of 7·2 ± 4·8 year (mean serum total calcium = 1·88 ± 0·16 vs 1·82 ± 0·36 mmol/l, P = 0·52; phosphorus = 1·81 ± 0·17 vs 1·87 ± 0·36 mmol/l, P = 0·53) in IH patients with and without anti-tTGAb. Although CaSRAb positivity was comparable in the two groups, IH patients with anti-tTGAb had higher TPOAb positivity (45·5% vs 12·8%, P = 0·02). Coeliac disease was diagnosed in only 2/9 patients with IH on biopsy, both of whom showed improved calcaemic control with a gluten-free diet. The prevalence of coeliac autoimmunity (6·4%) and coeliac disease (1·2%) in patients with IH seems to be similar to that in the general population. Notwithstanding this modest prevalence, it is important to be aware of the potential occurrence of coeliac disease with IH and the beneficial effect of a gluten-free diet on calcium control. © 2015 John Wiley & Sons Ltd.

Because of their complex design, duodenoscopes have been long recognized to be difficult to fully disinfect and may play a role in transmission of bacteria between patients. Recent reports of duodenoscope-associated carbapenem-resistant enterobacteriaceae transmission have confirmed these suspicions. An outbreak of a multidrug resistant strain of Escherichia coli was recently reported at our institution. Herein we report the results of our investigation and the process improvements that we deployed in an effort to contain the outbreak. A full investigation into the environment, endoscopists, infection control practices, high-level disinfection process as well as endoscopes was undertaken in conjunction with the local county health authority and the Centers for Disease Control and Prevention. Duodenoscopes were cultured and quarantined for 48 hours until negative cultures were obtained. Ergonomic changes were made to the endoscope reprocessing area, duodenoscopes were returned for routine maintenance, and surveillance cultures were obtained from all patients undergoing ERCP. Between November 2012 and August 2013, 32 patients were found to harbor 1 of 2 clonal strains of multidrug-resistant E coli, all of whom had undergone ERCP or duodenoscopy. A total of 1149 ERCPs were performed during this time period. Seven patients died within 31 days of the organism being identified in culture, 16 patients died overall by March 2015. The exact contribution of E coli to death is unclear because most patients had underlying late-stage malignancy or other severe medical comorbidities. No breach in high-level disinfection protocol or infection control practices was identified. The clonal strain of E coli was identified in culture on 4 of 8 duodenoscopes, 3 of which required critical repairs despite lack of obvious malfunction. The defect rate in high-level disinfection of duodenoscopes was 2% over a 1-year period. The implemented quality improvements, subsequent to which 1625 ERCPs have been performed, were successful in halting the outbreak. The existing manufacturer-recommended high-level disinfection protocols for duodenoscopes are inadequate. Although the ultimate solution may be a design change to the instrument, the timeline for such a change appears long and potentially difficult to exact. In the interim, a reliable method to ensure that bacterial pathogens are not present on the duodenoscope after high-level disinfection is needed.

AIM: To assess the esophageal motility in patients with irritable bowel syndrome (IBS) and to compare those with patients with autoimmune disorders. METHODS: 15 patients with IBS, 22 with systemic lupus erythematosus (SLE) and 19 with systemic sclerosis (SSc) were prospectively selected from a total of 115 patients at a single university centre and esophageal motility was analysed using standard manometry (Mui Scientific PIP-4-8SS). All patients underwent esophago-gastro-duodenoscopy before entering the study so that only patients with normal endoscopic findings were included in the current study. All patients underwent a complete physical, blood biochemistry and urinary examination. The grade of dysphagia was determined for each patient in accordance to the intensity and frequency of the presented esophageal symptoms. Furthermore, disease activity scores (SLEDAI and modified Rodnan score) were obtained for patients with autoimmune diseases. Outcome parameter: A correlation coefficient was calculated between amplitudes, velocity and duration of the peristaltic waves throughout esophagus and patients’ dysphagia for all three groups. RESULTS: There was no statistical difference in the standard blood biochemistry and urinary analysis in all three groups. Patients with IBS showed similar pathologic dysphagia scores compared to patients with SLE and SSc. The mean value of dysphagia score was in IBS group 7.3, in SLE group 6.73 and in SSc group 7.56 with a P-value > 0.05. However, the manometric patterns were different. IBS patients showed during esophageal manometry peristaltic amplitudes at the proximal part of esophagus greater than 60 mmHg in 46% of the patients, which was significant higher in comparison to the SLE (11.8%) and SSc-Group (0%, P = 0.003). Furthermore, IBS patients showed lower mean resting pressure of the distal esophagus sphincter (Lower esophageal sphincter, 22 mmHg) when compared with SLE (28 mmHg, P = 0.037) and SSc (26 mmHg, P = 0.052). 23.5% of patients with SLE showed amplitudes greater as 160 mmHg in the distal esophagus (IBS and SSc: 0%) whereas 29.4% amplitudes greater as 100 mmHg in the middle one (IBS: 16.7%, SSc: 5.9% respectively, P = 0.006). Patients with SSc demonstrated, as expected, in almost half of the cases reduced peristalsis or even aperistalsis in the lower two thirds of the esophagus. SSc patients demonstrated a negative correlation coefficient between dysphagia score, amplitude and velocity of peristaltic activity at middle and lower esophagus [r = -0.6, P < 0.05]. CONCLUSION: IBS patients have comparable dysphagia-scores as patients with autoimmune disorders. The different manometric patterns might allow differentiating esophageal symptoms based on IBS from other organic diseases. PMID:24151359
