Long-term results of LAGB have been rarely reported, although publications on the procedure are copious. Our long-term data found that BMI evolution is good, the complication and re-operation rates are acceptable and the overall long-term results of the Lap-Band system are good.
A first approach to laparoscopic placement of the adjustable silicone gastric band (ASGB) was begun in our institution in 1992. This work started on an animal model first. In the animal lab, details of laparoscopic dissection around the stomach have been defined. A new prototype of the adjustable silicone band for laparoscopic use has been devised. Four voluntary patients underwent this operation on the 1st, 2nd, and 3rd of September 1993. All the patients were female and the average weight was 116 kg (102-120 kg). The mean body mass index was 43 kg/m2 (36-49 kg/m2). No major operative difficulty was encountered. Immediate postoperative outcome was uneventful.
We introduced open adjustable silicone gastric banding (ASGB) for treatment of morbid obesity in our institution in 1991. It was done in a prospective study comparing ASGB with vertical banded gastroplasty (VBG) with regard to weight loss. After 200 cases of open ASGB and 210 VBG procedures and the encouraging weight loss results, we started laparoscopic placement of the adjustable silicone band. The initial work was done in an animal laboratory program where a new surgical protocol has been established. Details of the laparoscopic dissection around the stomach in a deep operative field and fatty atmosphere have been developed, and a laparoscopically implantable version of the adjustable silicone band (LAGB) has been devised. The first human laparoscopic ASGB procedure was performed in our institution on September 1, 1993. Altogether 350 patients had undergone adjustable silicone gastric banding (LASGB) procedures by May 1997 (277 women, 73 men). All the patients were morbidly obese, with an average preoperative weight of 118 kg (92-200 kg). The mean BMI was 43 kg/m2 (36-65 kg/m2). The conversion rate to laparotomy has been low (1.4%). Early complications have been rare, and pouch dilatation and stomach slippage have been the only significant late complications. The rate of these complications has been considerably improved by reducing the pouch volume and using more gastrogastric sutures. Evaluation of postoperative weight loss of LASGB patients compared with our VBG and ASGB (open) patients showed a similar curve.
BACKGROUND: laparoscopic placement of the adjustable silicone gastric band (ASGB) was begun in our institution in 1992. METHODS: this work started on the animal model first. In the animal laboratory, details of laparoscopic dissection around the pig's stomach were defined. A new prototype of the adjustable silicone band for laparoscopic use was devised. The first human laparoscopic ASGB procedure was performed in our institution on September 1, 1993; 37 patients have undergone this operation by May, 1994. There were 33 women and four men. The average pre-operative weight was 114 kg (92160 kg). The mean BMI was 42 kg m(2) (37-50 kg m(2)). RESULTS: no major operative difficulty has been encountered. Immediate post-operative outcome was uneventful except for one patient. CONCLUSION: the technique of laparoscopic ASGB is described. Preliminary weight loss is comparable to open ASGB and vertical gastroplasty, provided that the surgeon has mastered laparoscopy and open bariatric surgery.
A prospective comparative study, comparing vertical banded gastroplasty (VBG) with adjustable silicone gastric banding (ASGB) has been undertaken. The purpose of the study was to see if ASGB could produce weight loss as good as VBG. Patient population was similar and patients' choice was based on informed consent. Male/ female ratio and excess body weight were comparable in both groups. Early as well as late complications were minor and rare In both groups. The evaluation of the results was based on excess weight loss and BMI curves. Weight loss as well as BMI curves were quite similar in the two groups. A 50% excess weight loss has been obtained at 6 months, In both groups.
