Outcomes following laparoscopic sleeve gastrectomy versus Roux-en-Y gastric bypass in morbidly obese patients: A comparative study

Background: Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are the two most common bariatric surgery methods performed worldwide. We aimed to contrast the LSG versus LRYGB effect in morbidly obese patients on obesity associated comorbidities and weight loss. Methods: This retrospective comparative research was performed through the period from 2019 to 2023 on 100 morbidly obese cases. Patients were designed into LSG group (50 patients underwent LSG) or LRYGB group (50 patients underwent LRYGB). Results: Excess weight loss (EWL) at one year follow up was insignificantly different between LSG and LRYGB groups while it was significantly improved in LRYGB group than LSG group at two years follow up (P value =0.027). The changes in hypertension, hypothyroidism, diabetes mellitus, obstructive sleep apnea syndrome, and gastro-oesophageal reflux disease (GERD) after surgery were insignificantly different between LRYGB and LSG groups. The number of oral hypoglycemic drugs, number of anti-hypertensive drugs, and thyroxine dosage after surgery were insignificantly different between LSG and LRYGB groups. Regarding postoperative complications, 3 (6%) cases progressd new-onset GERD in LSG group while 4 (8%) patients developed internal hernia, and 1 (2%) patient developed ulcer at gastrojejunal anastomosis in LRYGB group with insignificant difference between,,
