Purpose:
Staple line leakage (SLL) and staple line bleeding (SLB) are the most relevant postoperative complications of sleeve gastrectomy (SG). It is controversial whether and which method of staple line reinforcement (SLR) can best reduce these complications. The primary objective of this study was to investigate whether reinforcement of the most proximal part of the staple line with synthetic buttressing material, a strategy we termed partial SLR (p-SLR), reduces the 30-day incidence of SLL.
Methods:
A retrospective search of medical records of all bariatric patients from 2010 to 2019 was performed. Patients who underwent SG with either p-SLR or non-SLR were included. Intraoperative and postoperative outcomes were analyzed before and after propensity score matching (PSM).
Results:
Data from 431 patients were analyzed (364 in the p-SLR group and 67 in the non-SLR group). No difference in the 30-day incidence of SLL was observed between the two groups. The 30-day incidence of SLB (1.1% vs. 6.0% in the p-SLR and non-SLR groups, respectively) was significantly lower in the p-SLR group. These results were confirmed by PSM analysis.
Conclusion:
Partial staple line reinforcement with synthetic buttressing material does not reduce the 30-day incidence of SLL. Although our analysis showed a significant reduction in the 30-day incidence of SLB in the p-SLR group, this result should be interpreted with caution.
