Laparoscopic Sleeve Gastrectomy with Roux en-Y Bypass (A Novel Modification) for Morbid Obesity: A Prospective Observational Study.

Abstract

Recently, obesity witnessed a dramatic increase and its related comorbidities have grown. Bariatric surgeries were developed to reduce weight. However, all techniques had their advantages and shortages. In this work, we aimed to assess our new modification of combining sleeve gastrectomy with Roux en-y bypass for the management of obesity, hoping to gain benefits from both techniques to increase the excess bodyweight loss (EBW%). The study was a prospective observational study on 23 Morbidly obese patients. The study was held from January 2020 to April 2022. The recruited patients were submitted to detailed clinical assessment and investigations to check fitness for surgery. Besides operative data, any intra- or post-operative complications were recorded. Each patient was followed up for at least one year. The follow-up visits were scheduled at regular intervals (one week, one month, six months, and twelve months). The mean operative time was 113.91 minutes (65-150). No intraoperative complications or conversion. There was intraluminal bleeding in one patient within 48 hours postoperatively with successful conservative management. There was a complete cure of diabetes mellitus (DM) for 5, 2, and 3 patients and antidiabetic drugs were reduced for 64.3%, 21.43%, and 7.14% at 1, 6, and 12 months follow up respectively. Hypertension was cured in 1,1,2 patients, and antihypertensives were reduced for 2,1,1 patient, at 1, 6, and 12 months follow up respectively. EWL% was 14.4%, 40.78%, and 73.74% at 1,6,12 months follow up respectively. Hemoglobin concentration and ionized calcium improved over time. Finally, serum albumin at 1, 6, and 12 months follow-up was 3.64, 3.58, 3.78 g/dL respectively. New modifications of combining LSG and LRYGB have shown to be safe and effective procedures. In addition, it is associated with minimal postoperative nutritional complications and permits complete visualization of the biliary system using endoscopy.
