OBJECTIVES: The aim of this study was to look at our intermediate outcomes after LDJB-SG.

SETTING: An academic medical center.

METHODS: A prospective analysis of T2D patients who underwent LDJB-SG between October 2011 and October 2014 was performed. Data collected included baseline demographic, body mass index, fasting blood glucose, glycosylated hemoglobin, C-peptide, resolution of co-morbidities, and postoperative complications.

RESULTS: A total of 163 patients with minimum of follow-up >1 year were enrolled in this study (57 men and 106 women). The mean age and body mass index were 47.7 (±10.7) years and a 30.2 (±5.1) kg/m2, respectively. There were 119 patients on oral hypoglycemic agents only, 29 patients were on oral hypoglycemic agents and insulin, 3 patients were on insulin only, and the other 12 patients were not on diabetic medication. Mean operation time and length of hospital stay were 144.7 (± 45.1) minutes and 2.4 (± 1.0) days, respectively. Seven patients (3.6%) needed reoperation due to bleeding (n = 1), anastomotic leak (n = 2), sleeve strictures (n = 2), and incisional hernia (n = 2). At 2 years of follow-up, there were 56 patients. None of the patients were on insulin and only 20% of patients were on oral hypoglycemic agents. Mean body mass index significantly dropped to 22.9 (±5.6) kg/m2 at 2 years. The mean preoperative fasting blood glucose, glycosylated hemoglobin, and C-peptide levels were 174.7 mg/dL (± 61.0), 8.8% (±1.8), and 2.6 (±1.7) ng/mL, respectively. The mean fasting blood glucose, glycosylated hemoglobin, and C-peptide at 2 years were 112.5 (±60.7) mg/dL, 6.4% (±2.0), and 1.5 (±0.6) ng/mL, respectively. No patient needed revisional surgery because of dumping syndrome, marginal ulcer, or gastroesophageal reflux disease at the last follow up period.

MATERIALS AND METHODS: Retrospective review on patients that had undergone conversion of OAGB to RYGB between June 2007-June 2019 in a tertiary bariatric center, followed by literature review.

RESULTS: Out of 386 revisional bariatric surgery, a total of 14 patients underwent laparoscopic conversion of OAGB to RYGB. The mean age was 44.7 with 71% female. The mean pre-revision BMI was 29.2 kg/m2. The primary indications for revision were bile reflux (n=7), marginal ulcer (n=3), inadequate weight loss or weight regain (IWL/WR) (n=3) and protein-calorie malnutrition (n=1). Conversion of OAGB to RYGB was completed laparoscopically in all cases. The mean length of stay was 4.1 days. There was no intraoperative or early post-operative complication. The mean total weight loss (rTWL%) after revision at year one, year three and year five post-revision were 11.5%, 18.1% and 29.1%, respectively. All patients achieved resolution of bile reflux and marginal ulcer. There was no mortality in this cohort.
