Background/Aim: In Japan, laparoscopic bariatric surgery has been performed since 2000. The number of the patients has gradually increased, and 152 patients underwent laparoscopic bariatric surgery in 2011. The most popular operations are now laparoscopic sleeve gastrectomy (LSG) and LSG with duodenal-jejunal bypass. We have performed laparoscopic adjustable gastric banding since 2005 and LSG since 2006. Here, our experience in LSG, together with Japanese experiences is presented. Methods: Since June 2006, 35 patients with 125kg averaged weight and 46kg/m2 BMI have undergone LSG. The inclusion criteria of LSG were morbid obesity (BMI>35kg/m2) with comorbidities. LSG was carried out using endoscopic linear staplers from the greater curvature of the antrum 5-6cm proximal to the pyloric ring to the angle of His alongside a 32-Fr endoscope. Staple-line reinforcement was performed by oversewing with 3-0 Vicryl in 21 cases and by buttress materials (Duet TRS, Covidien) in 13 cases. Results: All the procedures were laparoscopically completed, and no major complications such as staple-line leakage were experienced. Weight loss and % excess weight loss were 38kg and 57% after 12 months, and 44kg and 71% after 36 months. Accordingly, comorbidities such as type 2 diabetes and metabolic syndrome were frequently cured or improved. Conclusions: LSG is safe and effective in treatment for Japanese morbidly obese patients, and will be covered by the Japanese health insurance.
