ABSTRACT
BACKGROUND: Laparoscopic sleeve gastrectomy can lead to dangerous complications as leaks and hemorrhage. In addition, it can lead to gastric twist/torsion, prolonged postoperative nausea and vomiting (PONV), and de novo gastroesophageal reflux disease (GERD). We aimed to study the efficacy of omentopexy/gastropexy (OP/GP) in the prevention of these postoperative complications.
MATERIALS AND METHODS: PubMed and Google Scholar were queried in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data was analyzed using the Review Manager (RevMen) 5.4.1 software. Mantel-Haenszel statistical method and random effects analysis model were used in all meta-analyses. The odds ratio was used for dichotomous data. Subgroup analysis was done according to bougie size. Subgroup analysis according to the distance between the starting point of gastric transection and pylorus was not possible (limitation). Odds ratio and control event rate across studies were used to calculate the number needed to treat (NNT) with OP/GP for an additional beneficial outcome (prevention of adverse outcome) to occur.
RESULTS: The initial search identified 442 records; 371 were found irrelevant after screening and were excluded. The remaining 71 reports were retrieved and assessed for eligibility. An additional 57 reports were excluded following an in-depth assessment. The remaining 14 studies were included in this meta-analysis; 8 were nonrandomized studies (NRSs) while 6 were randomized controlled trials. Most studies originated from a single country (limitation). A statistically significant decrease in favor of OP/GP was observed for all outcomes (bleeding, leaks, gastric twist/torsion, prolonged PONV 1 month postoperatively, and postoperative de novo GERD). Data was consistent across studies (low I2), and subgroup analysis according to bougie size revealed no subgroup differences. However, this study had 3 limitations that does not allow for strong conclusions.
CONCLUSIONS: Although the current literature lacks strong scientific evidence, this study suggests that omentopexy/gastropexy (OP/GP) may offer protection against bleeding and leaks as a staple line reinforcement method, as well as against gastric twist/torsion, prolonged postoperative nausea and vomiting (PONV), and de novo gastroesophageal reflux disease (GERD) as a staple line fixation method. Therefore, it is worthwhile to proceed with large-scale, multicenter, randomized controlled trials to reevaluate our findings. Furthermore, conducting a comparison between OP/GP and other staple line reinforcement techniques would be beneficial.
