 note = {The accidental ingestion of a foreign body is not uncommon. However, the presence of a foreign body in the gallbladder is extremely rare. Here, we present a case of cholecystitis due to a fish bone that may have penetrated through the stomach wall and into the gallbladder without causing peritonitis. A laparoscopic cholecystectomy was performed; a fish bone, measuring 4.0 cm in length, was found in the gallbladder. To the best of our knowledge, this is the first such case to be reported., American journal of surgery, 198(2), pp.20-22; 2009},
