Reoperations were common in all groups .
Reoperation rate was initially high but reduced markedly with improved b and and surgical and aftercare techniques .
Conclusion All current procedures are associated with substantial and durable weight loss .
More long-term data are needed for one-anastomosis gastric bypass and sleeve gastrectomy  .
Reoperation is likely to remain common across all procedures
Introduction Durability is a key requirement for the broad acceptance of bariatric surgery .
A Prospective Randomized Trial of Placement of the Laparoscopic Adjustable Gastric Band: Comparison of the Perigastric and Pars Flaccida Pathways
Background : Laparoscopic adjustable gastric b and ing ( LAGB ) is a safe and effective method for the treatment of obesity . The most common problem after LAGB has been the occurrence of prolapse ( slippage ) of the stomach through the b and . It has been proposed that the pars flaccida ( PF ) pathway ( dissection from the base of the right crus , along the left crus to the angle of His ) is less likely to be associated with prolapse than the traditional perigastric ( PG ) pathway ( dissection between the lesser curvature of stomach and lesser omentum , across the apex of the lesser sac , to the angle of His ) . We have tested this hypothesis using a r and omized controlled trial format . Methods : We have performed a r and omized controlled trial to compare the outcomes after LAGB using PF and PG pathways .  202 patients ( mean age 40 years , mean weight 123 kg , mean BMI 45 ) were r and omly allocated to the PF or PG pathway and followed for 2 years . Results : At 24 months , there have been 16 revisional procedures for prolapse , 4 in the PF group ( all anterior prolapse ) and 15 in the PG group ( 12 posterior and 3 anterior ) . This difference is significant ( P<0.001 ) . The mean % excess weight lost was 53 % for the PF group and 46 % for the PG group . There was equally significant improvements in the metabolic syndrome in both groups ( 59 % preoperatively and 19 % at 2 years ) . All 8 paired domain scores of the SF-36 measures of quality of life were improved significantly in both group ( P<0.001 ) . Conclusions : The PF pathway is as effective as the PG pathway in generating substantial weight loss , improved health and improved quality of life and is significantly less likely to be associated with prolapse ( slippage ) . It is recommended as the primary dissection pathway
