Weight Loss and Improvement of Obesity-Related Illness Following Laparoscopic Adjustable Gastric Banding Procedure for Morbidly Obese Patients in Taiwan

Background/Purpose: Laparoscopic adjustable gastric banding( LAGB) is a newly developed minimally invasive surgical procedure for the treatment of morbid obesity. This study was conducted to evaluate body weight loss, surgical complications, and comorbidities after LAGB surgery. Methods : Ninety-one morbidly obese patients (mean age, 31.2 years; mean preoperative weight, 120.8 kg) underwent LAGB in a private Taiwan hospital setting within a comprehensive multidisciplinary bariatric program. Patients were followed up to 36 months. Comorbidities were assessed in 55 patients who completed more than 12 months of follow-up by comparing each comorbid condition before surgery and during follow-up. Results: All procedures were performed laparoscopically with no conversion. Mean operation time was 88.7 +/- 32.9 minutes. There were no intraoperative or major postoperative complications. Minor complication of stoma stenosis occurred in three (3.3%) patients. At 36 months after surgery mean body mass index had decreased from 42.7 to 33.9 kg/m(2), and mean percentage of excess weight loss was 44.8 %. Late complications were as follows: intractable vomiting requiring band removal in one (1.1%) patient, tubing problems requiring revision surgery in four (4.3%), and stoma obstruction in two (2.1%). There was no mortality. Resolution or improvement of comorbidities was significant for hyperglycemia and diabetes-related index , dyslipidemia, abnormal liver function, hyperuricemia, sleep apnea, and arthralgia, but not for hypertension. Conclusion: LAGB provides good weight loss and significant reduction in comorbidities with few minor complications
