PurposeThe aim of this long-term study was the comparison of appendiceal stump closure with polymeric clips or staplers with respect to perioperative costs and surgical outcome under routine conditions in a university centre.MethodsFor this retrospective chart review, a total of 618 patients undergoing laparoscopic appendectomy for suspected acute appendicitis between 2010 and 2017 were reviewed: 410 patients in the stapler group and 208 patients in the clip group. The database contained demographic data, operation time, inflammation parameters, closure method of the stump, surgeon status, length of hospital stay, and complications as well as histology reports. The costs were also compared.ResultsClip application was more likely among younger patients (mean age 33.6 years vs. 41.7 years). Histopathological evidence for appendiceal pathology was found in 96.6% of patients in the clip group and 99.5% of patients in the stapler group. Laparoscopic appendectomy in the clip group was more frequently performed by resident physicians (69.2%) than in the stapler group (57.8%). The mean postoperative stay was 2.9 days in the clip group and 3.7 days in the stapler group. The use of the polymeric clip resulted in considerable cost savings (19.94€ vs. 348.70€).ConclusionsThe use of polymeric clips for appendiceal stump closure during appendectomy is safe and effective. The base of the appendix is amenable to clipping in 32% of appendectomies in adult patients. This study supports the use of polymeric clips over staplers to decrease cost and environmental impact.
