Comparison Of Polymeric Clips And Endoscopic Staplers For Laparoscopic Appendectomy

Introduction: Appendectomy is the most common pediatric surgical procedure. To decrease the cost and environmental impact of single incision pediatric endosurgery (SIPES) appendectomy, we switched from using endoscopic staplers to polymeric clips placed with nondisposable laparoscopic appliers. The aim of this study was to compare the resulting reduction in cost and amount of waste generated per case, as well as to compare the perioperative variables and outcomes in patients in whom clips were used, with those of historical patients in whom staplers were used. Materials and Methods: Retrospective chart review of SIPES appendectomies was performed and patients in whom clips were used were compared with patients in whom staplers were used. Demographic, operative, and clinical data were collected. t-Test, Mann-Whitney test, and chi squared test were used to analyze the data as appropriate. The cost to the hospital of the clips and staplers was compared. The disposable waste generated from clips and the staplers was weighed. Results: A total of 246 patients were included: 111 in stapler group and 135 in clip group. There were no statistically significant differences between the groups in operative time, estimated blood loss, length of stay, and complications. There were no complications related to use of clips. In the clip group, staplers were used in 10% because base of appendix was too large, gangrenous, or perforated and could not be clipped. Use of polymeric clips was less expensive and generated less waste. Conclusions: Use of polymeric clips for appendectomy is safe and effective, and results are comparable with those of stapling. Based on our data, in 90% of appendectomies, the base of appendix is amenable to clipping. This study supports use of clips over staplers to decrease cost and environmental impact.
