Late reoperation for retained gallstone after laparoscopic cholecystectomy.

Complications due to retained gallstones after a laparoscopic cholecystectomy occur in 1.7 per 1000 cases. Significant delay to definitive diagnosis and treatment is common due to late presentation and nonspecific symptoms. Despite the low frequency, complications due to retained gallstones may be serious, including abscess and fistula formation. In the present case, we discuss the removal of abdominal wall and peritoneal stones 8 months after the original laparoscopic cholecystectomy. The case illustrates that complications may arise months to years after the original procedure and requires a high degree of clinical suspicion for expeditious diagnosis. Ultrasound is a sensitive and specific test to identify retained stones. Laparoscopic retrieval is recommended upon identification of intraperitoneal stones within this timeline.
