Background: Laparoscopic sleeve gastrectomy (LSG) is a quick and relatively simple
type of bariatric surgery which shows good resolution of co-morbidities and goodweight loss. We report on complications after LSG as a single-stage bariatric surgeryand the results of a survey on LSGs conducted by the Japan Research Society for
Endoscopic and Laparoscopic Treatments of Obesity.
Methods: Data were collected on all patients undergoing bariatric surgery betweenJanuary 2005 and December 2009, which included 340 patients from nine hospitals inJapan. We evaluated short-term morbidity in 102 patients undergoing LSG and excluded
patients undergoing LSG with duodenojejunal bypass.
Results: A total of 102 LSGs were successfully performed without conversions to anopen surgery. In 2004, there were no LSGs reported. In 2009, the mostcommonly-performed procedures were LSG (50 patients), laparoscopic gastric bypass(8), LSG with duodenojejunal bypass (8), and laparoscopic adjustable gastric banding(4). Approximately 8% of patients had perioperative complications. The most commoncomplications were staple line leaks (4%). Reoperation occurred in seven patients (7%),
four with bleedings and three with staple line leaks. No mortalities occurred. In oureight LSG patients, late gastric leak occurred in one patient; and it was treated with anendoscopic mucosal closure after failed attempts to treat the percutaneous abdominal
drainage.
Conclusion: The frequency of serious complications among patients undergoing LSG
was relatively low. It is a safe single-stage bariatric surgery for Japanese morbid obesity.
