title: Gastric stenosis after laparoscopic sleeve gastrectomy in morbidly obese patients.
abstract: Laparoscopic sleeve gastrectomy (LSG) is an effective bariatric procedure. The objective of this study is to describe a series of patients who were subjected to LSG and then developed gastric stenosis, with an emphasis on their treatment and a discussion of the possible underlying mechanisms. From January 2006 to October 2012, 717 patients with morbid obesity underwent LSG in our institution. Out of 717 patients, 571 (79.6 %) were women. The mean age was 36.9 years with a BMI of 37.3 kg/m(2). Five patients (0.69 %) developed gastric stenosis. Treatment of the stenosis was endoscopic dilatations; however, one patient required a conversion to laparoscopic Roux-en-Y gastric bypass. Stenosis after LSG is rare but requires early diagnosis and treatment.
