Background: Acute pancreatitis (AP) is a common cause of admission to the emergency room. Its etiopathogeny is poorly understood. The pancreatic inflammatory response in this process is unclear. The influence of the autonomic nervous system is a controversial issue.
Aims: To demonstrate the effects of truncular vagotomy on AP due to duodenal distention in the South American opossum. PLACE OF APPLICATION: Department of experimental surgery (Churruca-Visca Hospital) INEUCI (Neuroscience Institute, CONICET, UBA).
Population: Male and female South American opossum divided into: a control group (7 animals); group A: truncular vagotomy and pyloroplasty seven days after the onset of AP (7 animals). Group B: truncular vagotomy and pyloroplasty 30 days after provoking AP (7 animals). Group C: truncular vagotomy and pyloroplasty 45 days after the onset of AP (7 animals).
Methods: Acute pancreatitis was caused by duodenal distention of the second portion by inserting a Foley catheter through a gastrostomy.
Conclusions: The method of provoking AP is original. The influence of autonomous nervous system is being underestimated in most of the literature available.

Objective: We report the case of a 42-y-old morbidly obese woman who presented persistent anemia as result of Roux-en-Y gastric bypass.
Methods: The surgical procedure conducted in 1999 consisted of horizontal gastroplasty with truncular vagotomy, Roux-en-Y gastrojejunal anastomosis with an alimentary limb of 60 cm, and cholecystectomy. In 2000 a second surgery (subtotal gastrectomy, i.

Aim Of The Study: The aim of this prospective study was to report early results of videothoracoscopic truncal vagotomy in non-complicated chronic duodenal ulcers.
Patients And Methods: From 1995 to 1998, 250 patients suffering from chronic duodenal ulcer without pyloric stenosis were operated on in the main hospital of Dakar. They underwent videothoracoscopic truncal vagotomy without gastric drainage.

Aim: The aim of the study was to test the hypothesis that some patients with functional diarrhea could actually suffer from a mild clinical pattern of collagenous or lymphocytic colitis.
Patients And Methods: Twenty consecutive patients with chronic diarrhea were included in the study if the colonic mucosa appeared normal during colonoscopy. From multiple colonic biopsies were established a conventional histological diagnosis and a quantitative histological diagnosis.
