Complications of supraduodenal choledochotomy: a comparison of three methods of management.

The complications of elective choledochotomy in a prospective study of 116 patients with suspected intraduct calculi are reported. Management included T tube drainage (n = 59), primary closure of the bile duct (n = 29) and choledochoduodenostomy (n = 28). Septicaemia occurred in 12 patients (10%), with 1 death, and was unrelated to the type of operation. Thirty patients (26%) developed wound infection; this complication was more common after T tube drainage than the other procedures. Intra-abdominal abscess occurred in 3 patients only. Thrombo-embolism was recorded in 10 patients (9%), 7 of whom had an intraduct drain. Postoperative pancreatitis occurred in 5 patients (4%), with 2 deaths; a third of the patients in whom sphincteroplasty had been combined with supraduodenal choledochotomy developed this complication. Reoperation for stones was required in 3 patients with T tube; 3 patients developed a temporary biliary fistula after choledochoduodenostomy. The hospital stay was 9-5 days after primary closure, 14-0 days after choledochoduodenostomy and 16-8 days after T tube drainage. Wound sepsis (32%) and thrombo-embolism (12%) were more common in patients with bacterbilia than in patients where the bile was sterile at operation (13 and 3% respectively). Furthermore, wound sepsis, septicaemia and thrombo-embolism were reduced in patients who were given effective antibiotic cover.
