# Endoscopic Ultrasound-Guided Celiac Plexus Block-Induced Peripancreatic Abscess Requiring Transgastric Drainage

## TL;DR

A 49-year-old woman with chronic pancreatitis developed a peripancreatic abscess after a celiac plexus block, requiring endoscopic drainage.

## Contribution

This case report highlights a rare complication of CPB and emphasizes the need for proper clinical management.

## Key findings

- A CPB led to abscess formation in a patient with chronic pancreatitis.
- Medical therapy failed, necessitating transgastric drainage via endoscopic ultrasound.
- The case underscores the importance of managing postprocedural complications.

## Abstract

Endoscopic ultrasound-guided celiac plexus block (CPB) is a widely used technique for managing refractory abdominal pain in patients with chronic pancreatitis. Although generally safe, adverse events such as infection and abscess formation are important considerations in the risk profile of the procedure. We present a case of a 49-year-old woman with a history of chronic pancreatitis who developed an abscess at the site of a CPB that failed medical therapy and required endoscopic ultrasound-guided transgastric drainage. This case highlights the need for appropriate clinical application of CPB and the importance of recognition and management of postprocedural adverse events.
