Operative choledochoscopy.
We have reported the results of 121 examinations with the rigid choledochoscope performed by 13 different surgeons between 1969 and 1977. Pre-exploratory choledochoscopy was performed in 48 patients with a diagnostic accuracy of 94 per cent. Post-exploratory choledochoscopy was used in 73 patients to define whether the common bile duct had been adequately cleared of stones. Fifty-one patients were correctly assessed as having a clear duct and unsuspected residual calculi were demonstrated by choledochoscopy in 13 patients. However, choledochoscopy failed to identify 9 patients with retained stones. The accuracy of post-exploratory choledochoscopy alone was 87 per cent and the accuracy of post-exploratory cholangiography was 82 per cent, but when choledochoscopy was combined with post-exploratory cholangiography there were no errors. We conclude that the addition of choledochoscopy to conventional radiological techniques is likely to reduce the incidence of residual calculi after choledochotomy.

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.
