Background: Laparoscopic adjustable gastric banding (LAGB) has been a widely performed bariatric procedure. Unfortunately, revisional surgery is required in 20-30 % of cases. Data comparing revisional and primary gastric bypass procedures are scarce. This study compared revisional malabsorptive laparoscopic very very long limb (VVLL) Roux-en-Y gastric bypass (RYGB) with primary VVLL RYGB and tested the hypothesis that one-stage revisional laparoscopic VVLL RYGB is an effective procedure after failed LAGB.

Methods: In this study, 48 revisional VVLL RYGBs were matched one-to-one with 48 primary VVLL RYGBs. The outcome measures were operating time, conversion to open surgery, excess weight loss (EWL), and early and late morbidity.

Results: Surgical and medical morbidities did not differ significantly. No conversions occurred. The revisional group showed an EWL of 41.8 % after 12 months of follow-up evaluation and 45.1 % after 24 months based on the pre-revisional weight. The total EWL based on the weight before the LAGB was calculated to be 54.3 % after 12 months and 57.2 % after 24 months. The EWL in the primary RYGB group was significantly higher for both types of calculation: 41.8 %/54.3 % versus 64.1 % (p < 0.001 and >0.01) after 12 months and 45.1 %/57.2 % versus 70.4 % (p < 0.001 and <0.002) after 24 months.

Conclusions: Revisional laproscopic VVLL RYGB can be performed as a one-stage procedure by experienced bariatric surgeons but shows less effective EWL than primary RYGB procedures.
