Comparing quality of life outcomes between Laparoscopic Sleeve Gastrectomy and Laparoscopic Roux-en-Y Gastric Bypass using the RAND36 questionnaire

Abstract

Background: Obesity surgery is an effective treatment to improve the health of patients. There is a lack of data regarding weight loss surgery outcomes and effects on Quality of Life (QoL). This study aims to compare changes in QoL following either Laparoscopic Sleeve Gastrectomy (LSG) or Laparoscopic Roux-en-Y Gastric Bypass (LRYGB).

Methods: SF36 questionnaires were mailed to all LSG and LRYGB patients who underwent surgery in 2013. Demographic data was obtained from hospital records. Statistical analysis was undertaken using Stats direct.

Results: 158 patients were sent postal questionnaires. 60 were returned (38%). 41 were women, 16 LSG, 44 LRYGB, mean age 52 years, mean BMI pre-surgery 41.0. Both procedures yielded similar weight loss over 2 year follow up (p = 0.01), and similar improvements in obesity related co-morbidities. These procedures yielded significant improvements in all QoL scales and domains other than the emotional role limitations scale following sleeve gastrectomy.

Conclusion: Bariatric surgery has been shown to improve a patient's QoL. More research is needed to explain the reasons why there was a difference between Sleeve and Bypass procedures in emotional changes to patients.
