A modified combination technique for performing diagnostic peritoneal lavage.

Abstract

Existing open diagnostic peritoneal lavage techniques (DPL) use small bore catheters, through a small lower midline incision or infra-umbilical incision. This study evaluated a modified DPL technique using a 10 mm umbilical incision, with open insertion of a 20 French peritoneal lavage catheter. The catheter has 27 radial side holes in the terminal distal 13 cm, and a female Leur lock connector. Warmed saline is infused via a cystoscopy infusion set. The time required to perform a new technique was studied in 10 patients. The median time to catheter insertion was 2.4 +/- 3.8 min, infusion time 0.75 +/- 0.3 min, effusion time 0.3 +/- 1.7 min, and a median total time of 7.6 +/- 4.2 min (median +/- s.d.). There was no complications. This technique of DPL is cosmetically attractive, much quicker than existing techniques and we have found its initial use encouraging.
