A 14-year analysis of laparoscopic cholecystectomy: conversion--when and why?

Background: Contraindications to laparoscopic cholecystectomy diminished over the last decade but still conversion is about 5% to 6% in elective cases and higher in acute cholecystitis. The aim of this study was to analyze the reason for conversion in all patients operated on in our department and to create strategies for critical moments, which may need conversion.

Methods: From 1990 to 2004, operations have been divided in 3 groups: primary open cholecystectomy (OC), laparoscopic cholecystectomy, and conversion.

[Laparoscopic devascularization of the stomach and the abdominal esophagus with the LigaSure instrument in a porcine model].

Objectives: In this study we proved the feasibility of a new minimally invasive procedure for the devascularisation of the proximal stomach and the abdominal esophagus to prevent recurrent variceal bleeding in portal hypertension in a new animal model.

Materials And Methods: Experiments were performed on 12 female pigs, in two animal groups. In the first step (I.

Transilluminated powered phlebectomy: advantages and disadvantages of a new technique.

Objective: To evaluate this technique for its benefit and the technique-related risks and complications.

Methods: Thirty patients were prospectively operated with this new technique by the same surgeon (11 of them bilaterally [41 legs in all]).
