[Laparoscopic gastroplasty for morbid obesity: prospective study of 300 cases].
OBJECTIVE
Laparoscopic gastric banding for morbid obesity is noninvasive and reversible. The aim of this prospective study was to report the preliminary results of this procedure in the first 300 patients.


METHODS
From April 1997 to January 2000, 300 patients were laparoscopically operated for severe obesity: 266 women, 34 men, with a mean age of 40.1 years (range: 16-66). The mean preoperative weight was 118 kg (range: 85-195) and the mean body mass index (BMI) was 43.6 kg/m2 (range: 35.1-65.8). This is a recent and complete series with a mean follow-up of 10 months (range: 3-31). The primary endpoint was excessive weight loss (EWL) and the secondary endpoints were tolerance and morbidity.


RESULTS
There were no postoperative deaths. The mean operating time was 129 minutes (range: 50-380). A conversion to laparotomy was necessary in 11 patients. The mean hospital stay was 4.76 days (range: 3-42). There were 29 complications (9.6%), 16 among the first 50 procedures: 14 patients underwent an abdominal reoperation (2 perforations, 3 early slippages, 7 late slippages, 2 incisional hernias); 6 had respiratory complications with 2 ARDS and 9 developed a complication related to the port. At one year, BMI decreased from 43.6 to 33.7 kg/m2 and EWL reached 44.2%; 80% of the patients lost 60% of their excess weight.


CONCLUSIONS
Our experience is encouraging with an acceptable complication rate (5%) after 50 procedures. Slippage remains the main reason for close surveillance. Half of the excess weight can be comfortably lost in one year when the whole medical and surgical staff provide close support for each patient.
