Abstract
BACKGROUND: The outcome of bariatric surgery has been well documented in large series in the West. In Asia, where obesity has been less rampant, such surgery has been correspondingly less frequent, and there is a dearth of information on bariatric surgery on Asians. METHOD: The outcome of a personal series of 40 patients who underwent "gastric stapling" and banding from 1987 to 2003 in Singapore is analyzed. RESULTS: From 1987 to 1997, 26 patients underwent open bariatric surgery (Roux-en-Y gastric bypass 4, vertical banded gastroplasty 22). Initial mean BMI was 43.3 kg/m2. At 0.6, 1, 2, 4 and 8 years after surgery, mean BMI was 35.2, 31.9, 31.2, 31.1 and 34.1 kg/m2. Mean initial weight was 127.2 kg. %EWL was 42.2, 56.2, 56.9, 56.3 and 48.3%. From 1999 to 2003, 14 patients underwent adjustable gastric banding, 11 by laparoscopy. Initial mean BMI was 42.9 kg/m2. At 0.6, 1 and 2 years, mean BMI was 38.9, 36.6, and 32.6 kg/m2. Mean initial weight was 122.6 kg. %EWL was 26.6, 38.8 and 59.2%. One patient, following perigastric insertion of Lap-Band developed band slippage and gastric prolapse requiring removal. Since adopting the newer technique of combined pars flaccida and perigastric dissection in the last 6 patients, no band slippage has occurred. CONCLUSION: Our results of safety and low operative morbidity as well as the pattern and magnitude of weight loss following gastric stapling and banding for morbidly obese patients in Singapore appears to be similar to the Western experience.
