Initial Japanese experience with the LAP‐BAND system

Abstract

Laparoscopic bariatric surgery has gradually spread in Japan since it was introduced in 2000. In 2005, we introduced laparoscopic adjustable gastric banding (LAGB) with the LAP-BAND system into Japan. Here, we evaluate our intermediate-term results with the LAP-BAND system. Between August 2005 and June 2010, 27 Japanese patients with morbid obesity (BMI ≥ 35 kg/m(2) ) underwent LAGB with the LAP-BAND system in our institution. Our patients' average weight was 111 kg and BMI was 41 kg/m(2) . All LAGB procedures were performed through the pars flaccida pathway with band fixation using gastric-to-gastric sutures. The average follow-up period was 48 months. All procedures were completed laparoscopically. One early complication (sudden cardiac arrest due to postoperative bleeding) and three late complications (port trouble, megaesophagus, and band slippage) were experienced, and reoperations were performed in three of the patients. Weight loss and percentage of excess weight loss on average were 26 kg and 53% after 3 years and 22 kg and 53% after 6 years, respectively. In line with this good weight loss, comorbidities, especially those of type 2 diabetes and metabolic syndrome were frequently resolved or improved. LAGB with the LAP-BAND system appears to be beneficial in obese Japanese patients.
