OKUT, Gokalp et al. Management of the staple line bleeding in laparoscopic sleeve gastrectomy: monopolar cautery versus oversewing. Cir. cir. [online]. 2022, vol.90, suppl.1, pp.115-120.  Epub Jan 20, 2023. ISSN 2444-054X.


Staple line bleeding control (SLBC) after laparoscopic sleeve gastrectomy (LSG) is a serious problem. Cauterization alone is generally not preferred because of concerns about weakening the staple line. The aim of this study was to compare the suturing and monopolar cauterization methods for SLBC in LSG.


212 patients were divided into two groups as cautery and suture groups. Demographic characteristics, intraoperative, and post-operative results were analyzed.


Post-operative complications were seen in seven patients, four of them staple line bleeding (three patients were in the cautery group and one patient was in the suture group), and three of them leakage (all patients were in the suture group) from the staple line. There was no significant difference between the groups in terms of staple line bleeding (p = 0.35), staple line leakage (p = 0.09), blood loss (p = 0.12), intraoperative complications (p = 0.16), post-operative hemoglobin decrease (p = 0.63), and length of hospital stay (p = 0.35), but the operation time was longer in the suture group.


This is the first study in literature comparing monopolar cauterization with another technique. Monopolar cauterization can be used for SLBC in LSG. It is a safe and efficient method as well as inexpensive.
