Adjustable gastric banding in a public university hospital: prospective analysis of 400 patients.

BACKGROUND: Laparoscopic application of an adjustable gastric band (LAGB) is considered the least invasive surgical option for morbid obesity. It has the advantage of being potentially reversible and can improve quality of life. METHOD: Between April 1997 and January 2001, 400 patients underwent LAGB. There were 352 women and 48 men with mean age 40.2 years (16-66). Preoperative mean body weight was 119 kg (85-195) and mean body mass index (BMI) was 43.8 kg/m2 (35.1-65.8). RESULTS: Mean operative time was 116 minutes (30-380), and mean hospital stay was 4.55 days (3-42). There was no death. There were 12 conversions (3%). 40 complications required an abdominal reoperation (10%), for perforation (n = 2), gastric necrosis (n = 1), slippage (n = 31), incisional hernia (n = 2) and reconnection of the tube (n = 4). We noticed 7 pulmonary complications (2 ARDS, 5 atelectasis) and 30 minor problems related to the access port. At 2 years, mean BMI had fallen from 43.8 to 32.7 kg/m2 and mean excess weight loss (EWL) was 52.7% (12-94). CONCLUSION: LAGB is a very beneficial operation with an acceptable complication rate. EWL is 50% at 2 years if multidisciplinary follow-up remains assiduous. Surveillance for late anterior stomach slippage within the band is essential.

STUDY AIM: 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. PATIENTS AND 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. CONCLUSION: 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.

OBJECTIVES: The laparoscopic approach for gastroplasty is gaining widespread acceptance for morbid obesity. Less invasive and potentially reversible, this gastroplasty guarantees better quality of life. We thus evaluated perioperative complications in our consecutive series of 300 patients and followed the excessive weight loss (EWL) for the first 150. PATIENTS AND METHODS: Between April 1997 and January 2000, 300 patients underwent laparoscopic gastroplasty for severe obesity according to the NIH criteria: 266 women, 34 men, mean age 40.1 years (16-66 years). Mean preoperative weight was 118 kg (85-195 kg) and mean body mass index (BMI) was 43.4 kg/m2 (31.5-65.8). Two hundred one patients had 1.3 comorbidity due to excess weight. The first 150 patients were followed 15.5 months (12-31) without any lost to follow-up. Medical, dietary and psychological data were recorded every 3 months for 18 months. The main evaluation criteria was EWL; others were tolerance and morbidity. RESULTS: There was no death. Mean operative time was 129 minutes (50-380), mean hospital stay was 4.76 days (3-42). There were 11 conversions (3.6%). There were 29 complications (9.6%): 11 were postoperative (5 underwent an abdominal operation for 2 perforations, 3 early slippages; and 6 respiratory problems with 2 ARDS) and 18 were late complications (7 late slippages, 2 incisional hernias and 9 port problems). Follow-up of the first 150 patients was complete: at one year, BMI fell from 43.6 to 33.8 kg/m2 and EWL reached 50.5% at 18 months. CONCLUSION: Our experience is recent, but in light of the danger of the spontaneous course of morbid obesity, the results are encouraging due to the absence of mortality and the low rate of complications after the first 50 procedures. Half of the excess weight can be lost in one and a half years. Patient comfort remains quite acceptable with the active support of the surgery and medical teams.
