Innovative Approaches to Managing Postoperative Complications in Laparoscopic Sleeve Gastrectomy: A Scoping Review

Background: Laparoscopic sleeve gastrectomy (LSG) is an effective surgical intervention for obesity, but managing complications post LSG remains crucial. Given the global prevalence of obesity, innovative approaches are needed to improve patient outcomes. Objective: This scoping review aimed to comprehensively map the existing literature on innovative approaches for managing complications in adult patients undergoing LSG to treat morbid obesity. This management strategy may include surgical techniques, perioperative care, nutritional support, or other relevant strategies. Methods: A systematic search of PubMed and Scopus databases was conducted to identify relevant studies. The prespecified inclusion criteria were applied through a two-stage screening process. Studies involving adult patients who underwent LSG for morbid obesity (body mass index > 35) and those investigating interventions related to complications were included. The scoping review process adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. The results were summarized using a narrative approach. Results: This review included 31 studies with 4547 participants, showing diverse study designs, patient demographics, and surgical locations. Among them, 6 were case reports, 18 were randomized controlled trials, and 7 were retrospective studies. Complications of LSG include staple-line leaks, stenosis, hemorrhage, infection, gastric volvulus, and nutrient malabsorption. Innovative interventions, such as staple-line reinforcement, plication methods, and the Over-the-Scope Clip system, have been investigated for effective management. Conclusion: This scoping review provides valuable insights into innovative interventions for managing complications post LSG. This review highlights the need for further research to explore long-term outcomes, compare different interventions, and address the existing gaps in the literature.
