Retroperitoneal abscess after retained stones during laparoscopic cholecystectomy.
Laparoscopic cholecystectomy is associated with a significant risk of gallbladder perforations with bile and stone spillage. The retrieval of dropped stones is sometimes impossible, and intraperitoneally retained stones can be the source of serious complications, such as inflammatory masses or abscesses. The authors describe a patient in whom a large retroperitoneal abscess developed as a result of missed stone fragments during cholecystectomy. Although several cases of intraperitoneal abscess have been reported in the literature, retroperitoneal collection is very uncommon. Crushed and infected stones seem to be the essential prerequisite for abscess formation. Therefore, every attempt should be made to avoid stone spillage and intra-abdominally retained stones. Conversion to open surgery has to be considered in the presence of adverse factors, such as primary acute cholecystitis or cholecystitis induced by previous sphincterotomy, or bilirubinate stones believed to be infected. Abdominal abscess treatment requires removal of missed stones by surgical incision or new laparoscopic procedure because simple percutaneous drainage is usually unsuccessful.
