title: Laparoscopic bariatric surgery: a five-year review.
abstract: OBJECTIVE
  To review our results of laparoscopic adjustable gastric banding, laparoscopic sleeve gastrectomy, and laparoscopic gastric bypass for the treatment of morbid obesity.
  
  
  METHODS
  Prospective cohort study.
  
  
  METHODS
  Bariatric Surgery Centre, Prince of Wales Hospital, The Chinese University of Hong Kong, Hong Kong.
  
  
  METHODS
  All patients consisted of those referred to our Combined Obesity Clinic (to provide multidisciplinary weight management for severely obese patients) during the period July 2002 to December 2007. For patients who received bariatric surgeries as treatment of morbid obesity, peri-operative data, postoperative weight change, and co-morbidity improvements were collected and prospectively reviewed.
  
  
  RESULTS
  During the study period, 531 patients attended our Clinic for treatment of obesity. Their mean (standard deviation) body weight was 96 (22) kg, mean body mass index was 36 (6) kg/m(2), mean age was 40 (10) years, and 64% were female. Of these patients, 94 (18%) underwent bariatric surgery, which included: laparoscopic adjustable gastric banding (n=57), laparoscopic sleeve gastrectomy (n=30), and laparoscopic gastric bypass (n=7). Adverse events occurred in 11 (12%) of these 94 patients, but there was no operative mortality. At 2 years, the mean percentage weight loss for patients having laparoscopic adjustable gastric banding, laparoscopic sleeve gastrectomy, and laparoscopic gastric bypass were 34%, 51% and 61%, respectively. After operative treatment, obesity-related co-morbidities including metabolic syndrome, type 2 diabetes, hypertension, and sleep apnoea had also improved significantly.
  
  
  CONCLUSIONS
  Through a multidisciplinary weight management programme and various bariatric procedures, favourable results can be achieved in Chinese patients with severe obesity.
