Improving Laparoscopic Appendectomy Outcomes Using an Ileocecal Fold of Treves Buttress Technique

Laparoscopic appendectomy (LA) is the preferred treatment for acute appendicitis; however, it still presents a risk of complications such as infection and bleeding. Improper closure of the appendiceal stump can contribute to the development of postoperative complications. This study evaluates the efficacy of a novel buttress technique using the ileocecal fold of Treves to reinforce the staple-line closure of the appendiceal stump.

We conducted a retrospective cohort study involving 351 patients who underwent LA between 2022 and 2024 at 2 hospitals. Patients were divided into 2 groups: those who received the fold of Treves buttress technique (n = 90) and those who underwent standard staple closure (n = 261).

Our results demonstrate that using the fold of Treves buttress technique for securing the appendiceal stump during LA results in favorable outcomes, particularly in postoperative complication rates and length of stay for cases of perforated appendicitis.

The use of autologous tissue in this technique offers a cost-effective alternative to commercial buttress materials with the potential to improve patient outcomes in LA. Further studies are necessary to validate these findings and assess the broader applicability of this technique.
