Choosing between Roux-en-Y and Sleeve Gastrectomy for Morbid Obesity Bariatric Surgery

This systematic review aims to compare the methods of SG and RYGB used in bariatric surgeries regarding early post-surgical complications, weight loss and regain, gender, age, and ethnicity, as well as management of diabetes, hypertension, and dyslipidemia. Previous review articles have only examined some of the topics discussed here, making a general decision-leading comparison of SG and RYGB difficult. By compiling the most recent evidence in a single article, we hope to make data interpretation and procedure selection easier.

  • Abstract: Obesity is a worldwide epidemic affecting millions of people. Bariatric surgery is one method for tackling morbid obesity in people with a body mass index greater than 30 kg/m2. Vertical Sleeve Gastrectomy and Roux-en-Y gastric bypass (RYGB) are surgical techniques currently used in bariatric surgeries. It is critical to assess the benefits and drawbacks of each surgical technique to select the best option for each patient. Sleeve gastrectomy and RYGB were compared regarding patients' age, gender, ethnicity, weight loss, weight gain, early post-surgical complications, systemic hypertension, diabetes, and dyslipidemia. Studies about Sleeve and Gastric Bypass bariatric surgeries in adults who experienced weight loss and were published in the last five years were selected for a systematic review following the PRISMA guidelines. Non-human studies, nonrandomized studies, studies on gastric banding, and studies that did not address the topic or were irrelevant to the work were excluded. The mean age of the 45 studies chosen was 42 years old, with most patients female (63.2%). Despite a higher risk of post-surgical complications, RYGB was more effective than sleeve gastrectomy for systemic arterial hypertension, diabetes, dyslipidemia, and weight loss. Setting weight loss goals should be a collaborative effort between the doctor and the patient, and the limitations, risks, and benefits of bariatric surgery should be discussed before.
