Unusual Pancreatic Abscess Secondary to Embedded Fish Bone: A Challenging Clinical Scenario.

The incidental ingestion of fish bone is common, and the ingested fish bone mostly exits the gastrointestinal tract spontaneously. However, severe complications such as perforation in the digestive tract and abscess formation after a period of time may occasionally occur. Fewer than 10 cases of a migrated fish bone penetrating into the pancreas have been reported in the literature, and the development of a subsequent pancreatic abscess is extremely rare. We present one such rare case of pancreatic abscess formation in a middle-aged woman due to fish bone penetration through the gastric wall into the pancreas 2 months after ingestion and missed on endoscopy initially. Further imaging revealed that the fish bone was partially embedded in the pancreatic head surrounded with abscesses and was smoothly removed through laparoscopy.
