Risk-Benefit Comparison Between Endoloop and Endostapler Devices for the Closure of Appendiceal Stumps in Laparoscopic Appendectomy

Introduction Acute appendicitis is a common cause of acute abdomen and the most frequent surgical emergency in the world. Since the nineteenth century, surgical resolution has been the most accepted treatment worldwide, and laparoscopic appendectomy is currently preferred as the treatment of choice because it has several benefits. The closure of the appendiceal stump is the most crucial step during appendectomy since its inadequate management can cause post-surgical complications. Throughout recent years, several methods have been proposed to perform this closure. This study was performed to compare the post-surgical outcomes of the use of endoloop and endostapler devices. Methods This is a retrospective study of 290 patients aged 18 to 83 who underwent laparoscopic appendectomy between 2016 and 2020. Demographic data, clinical history, tomographic findings, and laboratory data were collected, as well as appendicular base management technique, severity degree of appendicitis at hospital admission, postoperative complications at 30 days, hospital readmission, and in-hospital stay. Statistical tests and binary logistic regression analyses were used to identify risk factors, with a significance level of p<0.05. Results Demographic data and clinical history did not show statistically significant differences. The presence of a pre-surgical abscess with tomography was 1.58 times higher in the endostapler group. Post-surgical results showed that the use of endostapler devices represented a 2.7 times higher risk of post-surgical abscess. The endostapler group was also found to have 1.87 times the risk of post-surgical sepsis. Conclusion Our study shows that the use of an endoloop reduces the risk of postoperative abscess by 16.5% and protects against the development of post-surgical sepsis by 30%.
