# Successful surgical internal drainage of postoperative pancreatic pseudocyst through pancreaticojejunostomy with distal pancreatectomy: a case report

## TL;DR

A 70-year-old man's pancreatic pseudocyst was successfully treated with a surgical procedure after other methods failed.

## Contribution

This case report presents a novel surgical approach using pancreaticojejunostomy for pseudocyst drainage when direct access was not possible.

## Key findings

- The pseudocyst was successfully drained using a pancreaticojejunostomy with distal pancreatectomy.
- An external pancreatic stent tube was used to facilitate drainage from the cut end into the duodenum.
- One month post-surgery, the pseudocyst had completely resolved.

## Abstract

Pancreatic pseudocyst is usually treated by percutaneous external drainage, endoscopic internal or external drainage, or surgical internal drainage such as cystogastrostomy. Surgical external drainage is an option if these procedures fail. We describe a case of a 70-year-old man with a pancreatic body pseudocyst that developed postoperatively. It was improved by endoscopic external drainage, and the stent was changed to an internal stent. However, surgery was required as the pseudocyst grew again. A direct approach to the pseudocyst was not possible because of severe adhesion. A distal pancreatectomy with pancreaticojejunostomy was performed, and an external pancreatic stent tube was inserted from the cut end into the duodenum to drain the pseudocyst. One month later, the pseudocyst disappeared, and the stent was removed.
