Relationship between directly measured portal pressure gradient and variceal hemorrhage.
It is commonly believed that variceal hemorrhage in patients with cirrhosis and portal hypertension does not occur below a portal pressure gradient (PPG) of 12 mm Hg. The aim of this study was to assess the relationship between directly measured portal pressure gradient and variceal hemorrhage. ⋯ The results of this study do not support the concept of a discrete bleeding threshold.

Review Case ReportsHemosuccus pancreaticus as a source of obscure upper gastrointestinal bleeding: three cases and literature review.
We report three patients with chronic pancreatitis and recurrent episodes of severe upper gastrointestinal bleeding caused by hemosuccus pancreaticus. No bleeding source could be identified despite repeated endoscopies. ⋯ No rebleeding occurred after operation. In cases of obscure upper gastrointestinal hemorrhage, the pancreas should be considered as a bleeding source, especially in patients with chronic pancreatitis.

Randomized Controlled Trial Comparative Study Clinical TrialEffect of triple therapy or amoxycillin plus omeprazole or amoxycillin plus tinidazole plus omeprazole on duodenal ulcer healing, eradication of Helicobacter pylori, and prevention of ulcer relapse over a 1-year follow-up period: a prospective, randomized, controlled study.
Triple therapy and amoxycillin plus omeprazole are the two most widely recommended regimens for the eradication of Helicobacter pylori. However, no controlled studies with a large number of cases are available for the reliable comparison of these two regimens. The aim of this controlled, randomized, prospective study was to compare the effect of these two regimens and a further regimen for metronidazole-resistant patients on duodenal ulcer healing, H. pylori eradication, and prevention of ulcer relapse. ⋯ The 2-wk triple therapy plus an additional 2-wk treatment with the bismuth derivative (without a prolonged administration of acid suppressing drugs) seems to be an effective and economic treatment not only for the eradication of H. pylori but also for the healing of acute DU. The higher incidence of side effects found after triple therapy compared with the other two regimens was tolerated by the patients.
