Development of a Two Port Laparoscopic Appendectomy Technique at a Rural Hospital.

Abstract

Background Laparoscopic appendectomy (LA) is most commonly performed using two 5-mm and one 10/12-mm ports. Various attempts to reduce the number and size of ports have been made and new technologies such as single port LA have been introduced. Appendix and mesoappendix are usually divided with a stapler or energy device with electrocautery, clips, and endoloop being cheaper options. Patients and Methods This study includes 51 consecutive LAs performed at a rural hospital. Patients were divided into 4 groups: group 1 was the standard technique group (n=12), group 2 served as a “try-out” (n=12), group 3 served as feasibility group (n=12), and group 4 was the final patient cohort in which the optimized technique was preferably used (n=15). Results Median age of the study cohort was 35.4 (range: 6.2-80.6) years, and 55% of patients were male. Whereas in G1 all patients had standard port placement (10/12-mm, 2x5-mm), in an increasing number of patients in G2-4 only two 5-mm ports and the 2.3-mm Teleflex minigrasper were inserted. Usage of staplers and/or energy devices was reduced from 100% in G1 to 20% in G4, and in the majority of cases both the appendix and the vascular pedicle were secured with an endoloop. The new technique did not add time to the procedure or total OR time. No stump-leaks or surgical site infections were encountered in this series, and there were no conversions to open surgery. Cost savings when not using a stapler or energy device are approximately 400$ per case; the minigrasper added approximately 200$ to the case. Discussion LA with use of two ports and a portless needle grasper is feasible in the majority of cases and was associated with high patient satisfaction and excellent cosmetic results. Avoiding energy devices and staplers is cost saving; the endoloop securely controls appendix and mesoappendix.
