Operative cholangiography: a perspective.

Two hundred and eighty-seven patients having operative cholangiograms were identified from a prospective study of 346 patients undergoing surgery for gallstones. Forty-two patients (14.6%) had filling defects and bile duct (BD) exploration. The false-positive exploration rate was 2.8%. Eight patients (2.8%) had unexpected BD calculi with no abnormality in pre-operative liver function tests or ultrasound. If a policy of selective operative cholangiography is pursued, then failure to detect a small number of duct stones must be expected, although unnecessary duct exploration is likely to be eliminated. The clinical significance of undetected BD calculi remains debatable.

Experience with biliary audit.

Experience with an audit of surgery for gallstones is discussed. Three hundred and forty-six patients were treated in a three and a half year period. There was no mortality. There was a duct exploration rate of 17%, an infection rate of 8.6%, and a re-operation rate for retained bile duct stone of 1.6%. Bile was cultured from 278 gall-bladders and culture was positive in 66 cases (23.7%). The most common organisms grown were coliforms and streptococci. Our antibiotic policy has changed as a result of this study. Audit is becoming increasingly necessary in surgical practice, not only for research purposes, but also to monitor performance. The design can be broad, to identify groups of patients for further study, or narrow, to concentrate on a particular problem. Someone must be responsible for checking the completed forms for accuracy before the data are entered into the computer. It is important that the form be as simple as possible. Forms which are too detailed will be filled in inaccurately or not at all.

The influence of colonoscopy on the operative management of colorectal cancer.

Total colonoscopy was used in the evaluation of 85 patients with colorectal cancer, either preoperatively or within six months of surgery. Synchronous lesions (six carcinomas, 22 adenomatous polyps, one villous adenoma and nine cases of severe diverticular disease) were detected in 38 (44.7%) patients. The planned surgical procedure was altered in 10 patients (11.8%)--a more extensive resection being performed in each case. In particular, five of the six cases of synchronous cancers were located in different surgical segments. Colonoscopy is a necessary prerequisite in the evaluation of patients with colorectal cancer.
