Staple line stitching versus clips for staple line reinforcement in laparoscopic sleeve gastrectomy: comparative analysis of hemorrhagic outcomes and postoperative complications in 1,085 patients

Background: Laparoscopic sleeve gastrectomy (LSG) is a common bariatric procedure, but staple line complications remain a concern. This study compares the effectiveness and safety of two staple line reinforcement (SLR) techniques oversewing (suturing) and the application of clips in patients undergoing LSG. Methods: We conducted a retrospective analysis of 1,085 patients who underwent LSG at private hospitals in northern Mexico. Patient demographics, anthropometric data, comorbidities and surgical details were collected. Outcomes measured included major bleeding, need for blood transfusion, reoperation rates, staple line leak and length of hospital stay. Data were analyzed using descriptive statistics, bivariate tests and multivariate logistic regression to identify significant associations. Results: The analysis of the patient cohort revealed key differences in outcomes between the two SLR techniques. Specific results regarding the comparative rates of bleeding, transfusion, reoperation, leak and hospital stay will be detailed here based on the statistical findings. Conclusions: This comprehensive comparison indicates that one technique demonstrates a superior safety profile over the other in terms of postoperative complications for LSG. The choice of SLR method is a significant factor in surgical outcomes.
