Abstract
BACKGROUND
Insufficient weight loss after primary laparoscopic sleeve gastrectomy (LSG) occasionally requires revisional surgery. A few single-institution studies have examined the safety of redo LSG (RSG) and have shown mixed results.
OBJECTIVES
The aim of this study was to evaluate the safety of RSG compared with LSG over a period of 30 days.
SETTING
University of Southern California, United States; Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database.
METHODS
The 2020-2021 MBSAQIP registry was used to evaluate patients who underwent RSG. Thirty-day outcomes were evaluated using univariable analysis and multivariable logistic and linear regression.
RESULTS
A total of 226,029 patients were reviewed, of whom 1454 (.7%) underwent RSG and 224,575 (99.3%) underwent initial LSG. Patients who underwent RSG were older (45 versus 42 yr), predominantly female (86.2% versus 81.3%), had a lower body mass index (40.0 versus 43.4), fewer co-morbidities, and greater rates of gastroesophageal reflux (38.7% versus 25.1%). They demonstrated increased overall complications (3.6% versus 2.1%, P < .001) and a longer operative time (81 versus 62 min, P < .001), but there was no difference in mortality. On multivariable analysis, patients who underwent RSG were independently associated with an increased risk of overall postoperative complications (odds ratio [OR]: 1.493, P = .018), organ space infection (OR: 6.231, P < .001), staple line leak (OR: 12.838, P < .001), pneumonia (OR: 3.85, P = .013), ventilator requirement over 48 hours (OR: 6.404, P = .035), sepsis (OR: 4.397, P = .010), septic shock (OR: 8.669, P < .001), reoperation (OR: 1.808, P = .013), readmission (OR: 2.104, P < .001), reintervention (OR: 4.435, P < .001), and longer operative times (β = 12.790, P < .001).
CONCLUSIONS
In this national database study, RSG was associated with increased rates of postoperative complications and a longer operative time. Although these results are concerning, further studies are required to examine long-term outcomes.
