Risk Factors for Readmission After Same-Day Discharge Sleeve Gastrectomy: a Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program Database Analysis.

BACKGROUND: Same-day discharge after sleeve gastrectomy (SG) is gaining popularity. We aimed to determine risk factors associated with readmission in patients who underwent same-day discharge SG. METHODS: We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database for the period 2015-2018. Patients who underwent SG and were discharged the same day of the operation were included in the analysis. Multivariable logistic regression analysis was performed to determine risk factors for readmission. RESULTS: A total of 466,270 SG were performed during the study period; 14,624 (3.1%) patients were discharged the same day and were included in the analysis. Mean age was 43.4 (14.7-80) years and 11,718 (80.1%) were female. Mean preoperative BMI was 43.7 ± 7.4 kg/m2. Mean operative time was 58.3 ± 32.4 min. Thirty-day reoperation, reintervention, and mortality rates were 0.7%, 0.7%, and 0.1%, respectively. Readmission rates were similar in same-day discharge and inpatient SG (2.9% vs. 3%, p = 0.5). Female sex (OR 1.52, 95% CI 1.15-2.00), preoperative gastroesophageal reflux disease (OR 1.33, 95% CI 1.08-1.64), renal insufficiency (OR 3.06, 95% CI 1.01-9.32), and intraoperative drain placement (OR 1.78, 95% CI 1.37-2.31) were independent risk factors for readmission following same-day discharge SG. CONCLUSIONS: Same-day discharge SG appears to be safe and is associated with low readmission rates. However, the identification of preoperative and intraoperative variables associated with higher risk of readmission might help defining safer and more effective same-day discharge protocols.

Minimally Invasive Revisional Bariatric Surgery in a MBSAQIP Accredited High-Volume Center.

Background: With the rising number of bariatric surgeries performed annually, there has also been an increase in revisional bariatric surgeries (RBS). The aim of this study is to evaluate the safety and postoperative outcomes of RBS performed with a minimally invasive approach. Methods: Retrospective analysis on a prospectively collected database of patients who underwent minimally invasive RBS between 2012 and 2019. Primary endpoints were conversion rate, major morbidity, mortality, and 30-day reoperation rate. Comparative analysis of laparoscopic adjustable gastric banding (LAGB) conversion to sleeve gastrectomy (SG) vs. conversion to Roux-en-Y gastric bypass (RYGB) was performed. Results: A total of 221 patients underwent minimally invasive RBS, 137 (62%) laparoscopically and 84 (38%) robotically. The most common RBS were LAGB to SG (59.3%) and LAGB to RYGB conversions (16.7%). The main indication was weight loss failure (88.7%). Conversion rate, major morbidity, and mortality were 0.9, 3.2, and 0.4%, respectively. Urgent reoperation was required in 3.2% of cases. Total weight loss at 1 and 2-years follow- were 14.3 and 17.3%, respectively. Comparative analysis of LAGB conversion to SG vs. RYGB showed similar major morbidity (SG: 2.3% vs. RYGB 0%, p = 1). Greater total weight loss was achieved in LAGB to RYGB conversions at 1-year (SG: 14.8% vs. RYGB 25.3%, p < 0.001). Conclusions: Minimally invasive RBS can be performed safely in a broad patient population with low conversion and complication rates, and improved weight loss outcomes. LAGB to RYGB conversions are associated with greater weight loss. Further randomized trials are needed to draw more conclusive recommendations.

Laparoscopic versus robotic-assisted Heller myotomy for the treatment of achalasia: A systematic review with meta-analysis.

BACKGROUND: Robotic-assisted laparoscopic Heller myotomy has been proposed as an alternative minimally invasive approach to traditional laparoscopy for the treatment of achalasia. This systematic review aims to compare the safety and post-operative outcomes of the two procedures. METHODS: Systematic literature search was performed in MEDLINE through Ovid, Scopus and Cochrane to identify clinical trials and retrospective analyses. Outcome measures used for meta-analysis included operative time, estimated blood loss, length of stay, 30-day readmission, intraoperative oesophageal perforation, conversion, mortality, morbidity, symptom relief beyond 1 year, re-intervention for recurrent symptoms and gastroesophageal reflux during follow-up rates. RESULTS: Seven studies were selected with a total of 3214 patients. The only factor to be statistically different is intraoperative oesophageal perforation rate, which is lower in robotic-assisted Heller myotomy compared to laparoscopic (odds ratio = 0.1139; 95% confidence interval [0.0334, 0.3887]; p = 0.0005). CONCLUSIONS: The results suggest a robotic approach is associated with improved patient safety.
