AIM: Laparoscopic appendectomy is currently the treatment of choice for acute appendicitis in emergency setting. When appendicitis is clinically suspected, an appendicolith can be found in 30% of the patients. Retained or dropped appendicoliths are an uncommon complication that may occur as a consequence of stone expulsion from the appendix, before or during laparoscopic appendectomies. This is very rare with only 30 reported cases of intra-abdominal abscess secondary to an appendicolith in the literature over the past 40 years. The objective of this case report is to illustrate an intrahepatic localization of a dropped appendicolith causing liver abscess.
CASE PRESENTATION: A 23-year-old female was admitted to the emergency department of our hospital for an acute appendicitis with coprolite obstructing the lumen and periappendicular effusion. Laparoscopic appendectomy was performed. Persistent liver abscess due to appendicolith was a rare complication treated by percutaneous drainage. The appendicolith was successfully removed from the liver parenchyma by Dormia basket recovery system.
DISCUSSION: Treatment options include percutaneous, open, or laparoscopic drainage of the abscess and retrieval of the fecalith, as antibiotics and drainage alone are usually insufficient.
CONCLUSION: Only a handful of cases of hepatic abscess formation as a result of dropped appendicoliths have been reported in literature. Our proposal of treatment was the percutaneous approach. There was no need for a surgical procedure to remove the intrahepatic appendicolith.
