Abstract
AbstractBackgroundLaparoscopic gastric bypass (LGB) is an increasingly utilized approach to bariatric surgery in Australia. A high proportion of those procedures are revisional due to Australia's legacy of laparoscopic adjustable gastric banding (LAGB), which is not the case internationally. The aim of this study was to compare post‐operative outcomes in an Australian general foregut surgery unit against benchmarks published in the literature.MethodsThis is retrospective cohort study of morbidly obese patients undergoing primary or revisional laparoscopic Roux‐en‐Y gastric bypass (RYGB) or laparoscopic one anastomosis gastric bypass (OAGB) with the two senior authors between 5 May 2015 and 27 June 2019. Perioperative data for the unit's first 100 cases were collected prospectively, stored on a unit database and analysed. Post‐operative complications at 30 days, 90 days, mortality, length of hospital stay, and Defined Adverse Events were chosen as indicators of the perioperative outcome (as defined in the Monash Bariatric Surgery Registry).ResultsIn this cohort, 35% of procedures were RYGB and 65% were OAGB. The majority (58%) were revisional procedures. Most patients (74%) were female. The median age was 50. The comorbidity profile of the population was similar to those published internationally. The median hospital stay was 4 days. There was no mortality. Early complications occurred in 9% of patients, with 3% occurring late.ConclusionOutcomes of our first 100 cases are comparable with those recorded in the literature, notwithstanding a much higher proportion of revisional cases. LGB can be safely introduced in Australian general foregut surgery units by experienced laparoscopic surgeons.
