Outcomes after laparoscopic ventral hernia repair: does the number of previous recurrences matter? A prospective study.

Background: It is not yet clearly known whether laparoscopic ventral hernia repair (LVHR) is superior to the open approach in recurrent hernias. The aim of this study is to determine the safety and efficacy of laparoscopic technique for ventral hernias and investigate whether these outcomes are affected by the number of previous failed repairs.

Methods: Data from 124 consecutive patients who underwent LVHR using a standardized technique between September 2007 and June 2014 were collected prospectively.

Colorectal anastomosis facilitated by the use of the LigaSure(®) sealing device: comparative study in an animal model.

Background: Recently, there has been speculation about the possibility of fusing intestinal tissue using bipolar sealing devices. In this study we compare in a porcine model the anastomoses created using the LigaSure(®) device with those created with a stapler after section and closure of a rectal stump.

Methods: Thirty pigs underwent laparoscopic colorectal anastomosis.
