Laparoscopic sleeve gastrectomy (LSG) has gained prominence as a therapeutic option for obesity and metabolic diseases. The choice of staple line reinforcement technique in LSG remains a subject of debate, particularly concerning postoperative bleeding complications.

The aim of this retrospective analysis is to assess the influence of different staple line reinforcement techniques on the occurrence of bleeding complications LSG.

Material and methods
We conducted a retrospective analysis of patients undergoing LSG between September 2021 and April 2023 at our institution. Patients were stratified into two groups based on the staple line reinforcement method: continuous suturing (n = 53) and clipping (n = 28). Surgical outcomes, including operative time, length of hospital stay, and bleeding complications, were assessed. Complications were classified using the Clavien-Dindo classification.

Continuous suturing was associated with a significantly longer operative time (88.15 min vs. 74.64 min, p < 0.05) but a similar length of hospital stay. Notably, no bleeding complications occurred in the continuous suturing group, while the clipping group experienced postoperative bleeding in 7.14% of cases (p < 0.05). Continuous suturing exhibited a slightly higher incidence of minor complications classified as Class I in the Clavien-Dindo classification (7.55% vs. 0%).

This retrospective analysis suggests that continuous suturing may provide enhanced hemostasis along the staple line, reducing the risk of postoperative bleeding compared to clipping. Despite the longer operative time and a slightly higher rate of minor complications, the clinical significance of these findings should be considered within the context of individual patient risk profiles.
