RESUMO

BACKGROUND/AIMS: We wanted to evaluate if the guidelines for appropriately performing colonoscopy by the American Society for Gastrointestinal Endoscopy (ASGE) yield good diagnostic efficacy, and we wanted to assess the appropriateness of referrals. METHODS: A total of 2,412 consecutive patients (1,605 men and 807 women) who were undergoing colonoscopy from September 2006 to February 2007 were prospectively enrolled in the study. The diagnostic yield was defined as the percentage of relevant colonic pathologies of the total number of performed colonoscopies. The 2000 ASGE guidelines were used to assess the appropriateness of the indications for the procedure. RESULTS: The large majority (64.2%) of patients had colonoscopy for an indication that was considered 'generally indicated', while the procedure was considered 'generally not indicated' for 22.4% of the patients. The diagnostic yield of colonoscopy was significantly higher for the appropriate colonoscopies (59.1%) than for the inappropriate colonoscopies (23.2%). On the multivariable analysis, the diagnostic yield was independently associated with the appropriateness of the indication that was "generally indicated" (odds ratio=9.5) and with the referrals by a gastroenterologist (odds ratio=1.7). CONCLUSIONS: The ASGE guidelines have shown a good diagnostic yield. Further steps are required to update and standardize the guidelines to increase the diagnostic yield.

RESUMO

BACKGROUND/AIMS: Gastric varices (GV) are one of the most serious complications of portal hypertension, but there is limited information on the clinical course of GV in Korea. The aim of this study was to elucidate the natural history of GV bleeding in Korean patients. METHODS: Of 604 patients with GV diagnosed between May 1995 and May 2005 at the Samsung Medical Center, 237 patients without a history of variceal bleeding or previous intervention for varices were investigated. The cumulative incidence rates of GV bleeding, long-term survival rates, and risk factors for GV bleeding were evaluated. RESULTS: The cumulative incidence rates of GV bleeding were 4.8%, 19.9%, and 23.2% at 1, 3, and 5 years after diagnosis, respectively. The overall survival rates were 88.6%, 53.2%, and 37.2% at 1, 5, and 10 years. In the univariate analysis, fundal varices, large (F3) GV, red color sign, and poor liver function (Child-Pugh class B or C) were significant risk factors for GV bleeding. In the multivariate analysis, large GV (hazard ratio 2.49) and poor liver function (hazard ratio 3.95) were the independent risk factors. CONCLUSIONS: GV bleeding was more frequent in patients with fundal varices than in patients with type 1 gastroesophageal varices, and large GV and poor liver function were risk factors for GV bleeding. Close observation and prophylaxis for variceal bleeding might be warranted in high-risk patients.

RESUMO

An ectopic pancreas is the presence of pancreatic tissue outside of its usual location. This condition rarely causes clinical symptoms, and the most commonly reported sites of these lesions are the stomach, the duodenum and jejunum. The presence of this ectopic tissue is not a rare condition, but its unusual locations, clinical symptoms, and complications are of clinical interest. We report a case of a gastric ectopic pancreas with recurrent upper gastrointestinal bleeding in a 20-year-old man.
