Increased susceptibility to oxidant injury in hepatocytes from rats with intra-abdominal hypertension.

Background: Intra-abdominal hypertension leads to visceral organ hypoperfusion, and subsequent decompression may cause ischemia-reperfusion, releasing toxic metabolites. This study focuses on the effect of intra-abdominal hypertension on hepatic antioxidant store and the susceptibility of hepatocytes to oxidant injury.

Methods: Sprague-Dawley rats (150-180 g) were acclimatized to an environment for 3 days and then divided into two groups according to challenge based on intra-abdominal pressure (0 and 30 cm H2O for control and experimental groups, respectively).

Ectopic pancreas with gastric outlet obstruction: report of two cases and literature review.

Ectopic pancreas is a rare entity and is usually an incidental finding in clinical practice. Most patients with an ectopic pancreas are asymptomatic, and if present, symptoms are non-specific according to the site of the lesion and different complications encountered. The most-common site is the stomach, accounting for 25%-38.
