Background/Aim: Since bariatric surgery had not been so popular in Japan, we introduced laparoscopic adjustable gastric banding (LAGB) for the treatment of morbid obesity into Japan. Here, our intermediate-term results were evaluated.
Methods: Between August 2005 and September 2010, 31 morbidly obese patients (18 women / 13 men, mean age of 39yr) received LAGB in our institute. All patients were morbidly obese (BMI>35 kg/m²), and the averaged weight was 118 kg and BMI was 43 kg/m². In regard to LAGB devices, LAP-BAND® (Allergan Medical) was used in 29 patients and SAGB® (OBTECH Medical GmbH) in 2 patients. All procedures of LAGB were performed through the pars flaccida pathway with band fixation using gastric-to-gastric sutures. Averaged follow-up duration was 35 months.
Results: All the procedures were completed laparoscopically. Two complications were experienced (postoperative bleeding and port trouble), and reoperations were needed in the patients. Weight loss and % excess weight loss on the average were 25kg and 44% after 1 year, 33 kg and 57% after 3 years and 29 kg and 51% after 5 years. Accordingly, comorbidities were frequently improved, and type 2 diabetes and metabolic syndrome were resolved in 9 of 10 patients (90%) and in 14 of 17 patients (82%), respectively.
Conclusions: LAGB will play an important role in treatment for Japanese morbidly obese patients in the near future.
