Early derivation operation can restore the pancreas histology and function in chronic obstructive pancreatitis in the cat.

Background/aims: Obstruction of the main pancreatic duct leads to progressive obstructive and atrophying pancreatitis in the cat. The question remains whether "early" derivative procedures can halt the destructive process or not?

Methodology: Twelve cats submitted to total obstruction of the main pancreatic duct developed chronic obstructive pancreatitis as documented by histopathology. After 5 weeks, five animals underwent a caudal pancreaticojejunostomy, the others served as controls.

Outcome after 'curative' surgery for carcinoma of the lower third of the rectum.

Background: Controversy exists about the optimal surgical resection for lower third rectal carcinoma. The aim of this retrospective study was to analyse whether the type of surgery is a significant predictor of outcome after curative surgery alone.

Methods: Eighty-two consecutive patients underwent abdominoperineal rectum excision (APRE, 41 patients) or sphincter-saving operation (SSO, 41 patients) for adenocarcinoma at 3.

Clinical and manometric effects of combined external beam irradiation and brachytherapy for anal cancer.

This study evaluates anorectal function after combined tele- and brachytherapy for anal cancer using manometric measurements and a standardized questionnaire. Eight patients received 44 +/- 3 Gy external beam radiation followed by 20 +/- 4 Gy interstitial brachytherapy with iridium-192. Patients were examined 43 months (range 25-83) after therapy.

Surgery for gastric remnant carcinoma following Billroth II gastrectomy.

Between January 1983 and December 1995, 31 patients with gastric remnant carcinoma were operated on 6-45 years after a Billroth II resection for peptic ulcer disease. Total gastrectomy with Roux-en-Y reconstruction was performed in all cases. In 16 patients (52%) extended resection with removal of one or more adjacent organs was necessary for oncological reasons.
