Translumbar retroperitoneal endoscopy: an alternative in the follow-up and management of drained infected pancreatic necrosis.

Background: The follow-up of drained infected pancreatic necrosis (IPN) is usually done with data on the patient's clinical evolution and information obtained from serial helical computed tomographic scans. Management often requires necrosectomies and periodic debridements.

Hypothesis: Translumbar retroperitoneal endoscopy is effective in the management of drained IPN.
