Venocutaneous fistula.

This is the first description of venocutaneous fistula, a late complication of elective laparoscopic cholecystectomy that arose 18 months after the initial operation. Postoperatively, the patient twice developed an abscess in the abdominal wall at the former site of the umbilical trocar. The first abscess occurred on the 6th postoperative day; the second, after 14 months. After an additional 4 months, a fistula opening appeared just below the umbilicus. Fistulography revealed a connection with the venous system of the omentum majus. During subsequent resection of the fistula, a pigment gallstone was retrieved from the base of the fistula.
