Laparoscopic-assisted placement of a peritoneal dialysis catheter with partial omentectomy and omentopexy in dogs: an experimental study.

OBJECTIVE: To describe a technique of laparoscopic-assisted placement of a peritoneal dialysis (PD) catheter with simultaneously performed partial omentectomy and omentopexy.

STUDY DESIGN: Pilot experimental study.

ANIMALS: Beagle dogs (n = 6).

METHODS: After placement of 1 sub-umbilical laparoscope portal and 1 instrument portal in the left cranial abdominal quadrant, laparoscopic-assisted partial omentectomy, and omentopexy were performed, and a modified Tenckhoff PD catheter was placed under laparoscopic guidance. A modified dialysis protocol was used twice daily for 4 days. The feasibility of the procedure, surgical duration, operative complications, and dialysis efficacy were evaluated. Postoperative pain and inflammation were graded (0-3).

RESULTS: The procedure was successfully performed in all dogs with a median operating time of 25 minutes. No operative complications occurred. Procedure-related postoperative pain and inflammation were minimal. Eight consecutive PD procedures were successfully performed, and no leakage or obstruction was observed.

CONCLUSIONS: Laparoscopic-assisted partial omentectomy and omentopexy can be performed at the same time as PD catheter placement with minimal morbidity.
