Unexpected outcome (positive or negative) including adverse drug reactions: An unusual hernia: losing a stone is not always a good thing!

摘要

A 42-year-old woman presented to the surgical outpatient department with what appeared to be a strangulated recurrent paraumbilical hernia. She was taken to theatre, where exploration revealed an unexpected diagnosis: an abdominal wall abscess that had formed around what appeared to be a gallstone dropped at the umbilical port site of a laparoscopic cholecystectomy performed 10 years previously. The abscess was incised and drained and a connection with the abdominal cavity excluded. The patient made a full recovery. Complications relating to spilled gallstones are rare, but can present in a variety of ways and sometimes many years after the original surgery. They should always be considered in a patient with a history of cholecystectomy presenting with an abdominal wall mass. There is no clear evidence of the best imaging modalities to be used for investigation. Methods for reducing the risk of such complications and the principles of different treatments are discussed.
