Parasitic Appendicitis: A Novel Laparoscopic Approach for the Prevention of Peritoneal Contamination.

BACKGROUND/AIM: Although rare, parasitic infection can cause acute appendicitis and result in contamination of the peritonea during appendectomy. The goal of this study was to summarize our experiences with parasitic appendicitis and describe a novel laparoscopic technique to prevent contamination.

METHOD

All patients diagnosed with acute appendicitis who underwent appendectomy between January 2016 and January 2017 were included in the study. All appendectomies were performed using the standard three-port laparoscopic method, and a video recording was made of each procedure. Following separation of the mesoappendix, a single endoloop was placed in the base of the appendix, and the appendix was then transected 3-4 mm above the clamp with the aid of a thermal cauterizing/sealing device. The appendix was extracted from the 10 mm trocar hole below the umbilicus and placed inside a bag prepared from a glove. After pathological confirmation of parasitic appendicitis, medical records were retrospectively analyzed in each case for whether peritoneal contamination had occurred or not.

RESULTS

Out of 97 appendectomies, parasitic infection was observed in 4 cases, as confirmed by pathological examination. In two of these patients, was detected, while the other two were infected with . Intraoperative contamination did not occur in any of the cases, and retrospective review of the video recordings indicated no peritoneal contamination.

CONCLUSION

As a result of the coagulation and sealing effects of thermal devices, airtight seals were created on the residual appendiceal stumps, and consequently, no contamination was observed in any of the cases.
