Granulomatous peritonitis after laparoscopic cholecystectomy

Granulomatous peritonitis may indicate a number of infectious, malignant, and idiopathic inflammatory conditions. It is a very rare postoperative complication, which is thought to reflect a delayed cellmediated response to cornstarch from surgical glove powder in susceptible individuals. This mechanism, however, is much more likely to occur with open abdominal surgery when compared with the laparoscopic technique.

We report a case of sterile granulomatous peritonitis in an 80-y-old female after a laparoscopic cholecystectomy. Management was conservative, and no relapse was observed after over 1-y of follow-up.

We propose that peritoneal exposure to bile acids during the laparoscopic removal of the gallbladder was the trigger of granulomatous peritonitis in this patient. Severe complications, such as peritoneal adhesions, intestinal obstruction, and fistula formation, were observed, but no fatalities were reported.

We should be aware of this rare cause of peritonitis in the surgical setting.
