Accurate localization and extraperitoneal drainage of pancreatic abscess.

Localization of a pancreatic abscess can be difficult. CT scanning can confirm the presence of an intraabdominal collection and define its extent. Five consecutive patients with pancreatic abscess have been investigated by CT scanning and the site and extent of the abscess defined. Extraperitoneal dissection with drainage was undertaken in all five patients. In four patients the abscess resolved completely, and in one laparotomy with further drainage was necessary. No complications occurred as a result of the procedure.
