Background: Vertical banded gastroplasty (VBG) and sleeve gastrectomy(SG) are purely gastric restrictive procedures designed to reduce appetite by decreasing the size of the stomach. Butterfly gastroplasty, is a modification of (VBG) in which a micro funnel shaped pouch was constructed limited to cardia in order to reduce the risk oflong-term staple-line disruption. This study presents preliminary results of our early experience with both procedures.
Methods: From August 2010 till August 2012 (60) consecutive patients with morbid obesity (9 males and 51 females) divided into two groups, (group 1) underwent laparoscopic butterfly gastroplasty (30 patients) and (group 2) underwent laparoscopic sleeve gastrectomy (30 patients). This study aimed to compare the preliminary results of both procedures including operative morbidity and mortality, short and long-term complications, as well as follow-up rates and parameters of weight loss.
Results: There were 6/30 (20%) and 3/30 (10%) cases with intra-abdominal bleeding in butterfly gastroplasty and sleeve gastrectomy groups respectively. In butterfly gastroplasty group, one (1130) early complication (3.3%) was encountered, late complications occurred in one (1130) patient (3.3%) with no mortality occurred; two patients had persistant vomiting. In sleeve gastrectomy group, two (2130) early complications (6.7%) (leakage arising from stable line of the stomach) were encountered with no late complications or mortality occurred. Substantial weight loss occurred in all patients. For butterfly gastroplasty group mean excess weight loss (EWL %) was 41.99±6.17 % at 6 month and 64.02±5.16% at 1 year, while for sleeve gastrectomy EWL% was 41.12±3.7 % at 6 month and 53.85±5.44% at 1 year. The rate of complete resolution of co-morbidities in butterfly gastroplasty was 100% for hypertension at 6 month and diabetes mellitus at 12 month, while in sleeve gastrectomy group resolution of hypertension was 90.9% and diabetes mellitus was 92.6% at 12 month
Conclusion: Butterfly gastroplasty and sleeve gastrectomy are feasible and safe restrictive bariatric procedures, with good short-term results and low morbidity rates. In comparison to sleeve gastrectomy, Butterfly gastroplasty has higher intra-operative complication rate (in the form ofbleeding), however it has also higher percentage of postoperative excess weight loss as well as reduction of assoiated preoperative morbidities.
