Laparoscopic Sleeve Gastrectomy (LSG) v/s One Anastomosis Gastric Bypass (OAGB): comparing quality of life after bariatric surgery

Abstract

Introduction: Various studies have shown that obesity affects people’s physical, mental and psycho-social functioning in turn affecting the Quality of Life (QoL). Research has shown an improvement in QoL after Bariatric Surgery. Objectives: The main aim of the study was to see whether there was any difference in QoL among patients undergoing LSG and OAGB at one and a half year after surgery. Methods: 32 patients (16 matched pairs each on age, gender and BMI), males and females had a mean age of 48.75 years. The mean BMI was 45.25kg /m2 and 41.56kg /m2 for OAGB and LSG respectively. They were administered a standardized scale: Impact of Weight on Quality of Life (IWQoL) at baseline and one and a half year post surgery. Results: Mean BMI dropped to 27.31 kg /m2 and 29.20 kg /m2 for OAGB and LSG respectively. The Mean total score on QoL scale pre-op was 12.93 and 10 and post-op 93.69 and 80.3 for OAGB and LSG respectively. But no statistically significant difference is seen among the LSG and OAGB groups on post op score on QoL. Conclusion: OAGB and SG both improve QoL. Larger sample size and longer duration studies are required to re-evaluate the same.
