# Nephroscope-Assisted Debridement of Pancreatic Necrosis Using the Palanivelu Hydatid Trocar Cannula System: A Novel Technique

## TL;DR

A new technique uses a specialized cannula system to drain infected pancreatic necrosis when other methods fail.

## Contribution

The novel use of the Palanivelu hydatid trocar cannula system for nephroscopy-assisted drainage of pancreatic necrosis is introduced.

## Key findings

- The Palanivelu system allows simultaneous irrigation and suction, which is beneficial for debridement.
- This technique may be effective in cases where percutaneous drainage fails.
- The method has not been previously described in the literature.

## Abstract

Percutaneous catheter drainage has been proven to be an effective treatment for infected pancreatic necrosis and pancreatic abscess. In cases with failure of drainage of pancreatic necrosis by percutaneous catheters, video-assisted retroperitoneal debridement (VARD) has been recommended. The Palanivelu hydatid trocar cannula system has been developed for its use in laparoscopic management of hydatid cyst disease, as it allows for simultaneous irrigation and suction of daughter cysts. We describe our technique of nephroscopic-assisted drainage of infected pancreatic necrosis using the Palanivelu hydatid trocar cannula system, which, to the best of our knowledge, has not been described in the literature to date.
