[Sustained weight loss 2 years after laparoscopic adjustable gastric banding for morbid obesity]

Abstract

Objective: To analyse the results of the laparoscopic adjustable gastric banding (LAGB) procedure for morbid obesity. DESIGN. Retrospective, descriptive.

Method: From November 1, 1995 to May 31, 2005, laparoscopic adjustable banding surgery was performed in St. Antonius Hospital, Nieuwegein, the Netherlands, in 411 patients. Inclusion criteria were BMI > or = 40 kg/ m(2) or BMI > 35 kg/m(2) and severe comorbidity with > 3 attempts at weight loss in the past. Selection, inclusion and follow-up were performed in a specialised, multidisciplinary setting. Height, weight, and complications were prospectively recorded. In 1995-2000 the perigastric surgical procedure was used and in 2000-2005 the pars-flaccida method.

Results: The study group consisted of 350 (85%) women and 61 (I5%) men with a median age of 38 years (range 17-60). Out of these 411 patients, the median weight was 133.4 kg, the median overweight, 69.6 kg and the median BMI 46.3 kg/m2. Two years after surgery, data was known for 267 patients where 206 (77%) had a weight loss > 30%, and 7 patients (3%) a weight gain. The median BMI difference was then -10.2 kg/m2 (range +4.7--26.4). The median loss of overweight was 46.3% (+10.00--97.8). The weight loss remained stable in the following years. The most commonly seen complications were fundus slippage (13%) and port-a-cath related complications (7%). These occurred more often in patients who had had the perigastric method surgery than in the parsflaccida surgical method.

Conclusion: Three quarters of the patients with morbid obesity who received laparoscopic gastric banding surgery had achieved and sustained weight loss at 2 years following surgery. The pars-flaccida method resulted in fewer complications than the perigastric surgical method.
