Portomesenteric vein thrombosis after laparoscopic sleeve gastrectomy.

Introduction: Portal and mesenteric vein thrombosis are relatively uncommon surgical complications, with difficult diagnosis and potentially severe consequences due to higher risk of bowel infarction. The purpose of this study was to present a series of patients who developed postoperative portal vein thrombosis after laparoscopic sleeve gastrectomy.

Methods: This is a retrospective analysis of patients who underwent sleeve gastrectomy between June 2005 and June 2011 who developed portal vein thrombosis.

Laparoscopic sleeve gastrectomy as a stand-alone procedure for morbid obesity: report of 1,000 cases and 3-year follow-up.

Background: Laparoscopic sleeve gastrectomy (LSG) is an emerging surgical technique with encouraging results. The objective of this study is to report surgical results after 1,000 consecutive LSG cases as a stand-alone procedure for morbid obesity during a 3-year follow-up.

Methods: Data were obtained by review of our prospectively maintained database, patients' clinical charts, and phone interview of all patients who underwent LSG in our institution from December 2005 to February 2010.
