Tensile Strength After Closure of Mesenteric Gaps in Laparoscopic Gastric Bypass: Three Techniques Tested in a Porcine Model.
BACKGROUND: Internal hernias occur frequently after laparoscopic gastric bypass. We have found no data on the relative strength of the various techniques available for closing these defects. The present study was performed to obtain such data to form a theoretical basis for clinical studies. METHODS: Six piglets were operated laparoscopically and four loops of small bowel created in each. These me
