Long-term results of mesocaval shunts with polytetrafluoroethylene grafts.

Despite the introduction of new procedures such as pharmacologic reduction of portal pressure and endoscopic sclerotherapy, the role of surgery in portal hypertension must be reconsidered. The aim of this retrospective study was to evaluate the long-term results of mesocaval interposition shunting in the treatment of recurrent variceal bleeding after sclerotherapy failure or in patients with intractable ascites in whom optimal medical treatments failed. Over a 20-year period, 85 patients (66 men and 19 women; mean age, 53.

[Ewing sarcoma of the mesocolon].

This case-report studies the clinical, radiological, anatomopatholo-gical and therapeutic aspects of peripheral primitive neuroectodermal tumours (PNET). PNET are neoplasms with a similar histology to tumours in the Ewing family. Diagnosis requires histopathology, immunohistochemistry and cytogenetic studies.

Platelet-activating factor in cirrhotic liver and hepatocellular carcinoma.

Aim: Platelet-activating factor (PAF) is a pro-inflammatory and angiogenic lipid mediator. Here we aimed to investigate levels of PAF, lyso-PAF (the PAF precursor), phospholipase A(2) (PLA(2), the enzymatic activity generating lyso-PAF), acetylhydrolase activity (AHA, the PAF degrading enzyme) and PAF receptor (PAF-R) transcripts in cirrhotic liver and hepatocellular carcinoma (HCC).

Methods: Twenty-nine patients with HCC were enrolled in this study.

Stapled hemorrhoidopexy versus milligan-morgan hemorrhoidectomy: a prospective, randomized, multicenter trial with 2-year postoperative follow up.

Purpose: The purpose of this study was to compare the outcome of stapled hemorrhoidopexy (SH group) performed using a circular stapler with that of the Milligan-Morgan technique (MM group). The goals of the study were to evaluate the efficacy and reproducibility of stapled hemorrhoidopexy and define its place among conventional techniques.

Methods: A series of 134 patients were included at 7 hospital centers.

Rectal injury caused by personal watercraft accident: report of a case.

A 16-year-old male riding as a passenger on a personal watercraft fell behind the jet nozzle while jumping waves. An unusual rectal injury caused by the accident and resulting in the death of the patient is presented. The surgical management and postoperative course is discussed.

Laparoscopic repair of small bowel injury in penetrating abdominal trauma.

A role for laparoscopy in the management of selected trauma patients is now possible. We report a case of a patient with a stab wound and a bowel perforation who underwent diagnostic and laparoscopic treatment.

[Perforated juxta-papillary duodenal diverticula: two cases].

Perforation of juxta-ampullary duodenal diverticula, occurring spontaneously or after abdominal trauma, is a severe condition. Diagnosis is difficult to establish and is based on tomodensitometry, which is the most reliable diagnostic tool. Treatment consists in diverticulectomy that can be associated with drainage of the duodenum or anastomosis between digestive and biliary tract.
