Two hundred and twenty-three patients with colorectal carcinoma were treated consecutively at the University Hospital of South Manchester from May 1976 to January 1981. Twenty-four patients (10.7 per cent) were found to have more than one colorectal carcinoma. In 18 patients this was recognized either immediately or within 6 months of the initial diagnosis--synchronous carcinoma. In the other six cases a second carcinoma was found at a later time--metachronous carcinoma. The incidence of synchronous, and consequently the combined incidence of synchronous and metachronous carcinoma, was higher than previously documented. The anatomical distribution of the multiple carcinomas and the sex incidence in these patients was similar to that seen in patients with a single carcinoma of the large bowel. A high association of adenomatous polypi with multiple large bowel carcinomas was observed. The possibility of more extensive colonic resection in the younger patient with a favourable carcinoma is discussed.
There is controversy concerning the subsequent clinical course of patients whose gallbladder is left in situ following successful endoscopic removal of stones from their common bile ducts. A total of 191 patients (median age 76 years) were reviewed between 12 and 100 months (mean 38 months) after endoscopic sphincterotomy. Ten patients (5.2 per cent) had symptoms requiring cholecystectomy which was uneventful, nine in the first year. Cholangitis at presentation or failure to fill the gallbladder by endoscopic retrograde cholangiography were not helpful in identifying these patients. Forty-nine (25.6 per cent) patients died during the review period from non-biliary pathology (usually cardiovascular). Elective cholecystectomy is not required in elderly patients with symptomatic bile duct stones if the common bile duct can be cleared of stones after endoscopic sphincterotomy.
An 8 year experience of 602 patients (median age 76 years) referred for endoscopic management of common bile stones is reported. No patient referred for treatment has been excluded. A diagnostic cholangiogram was achieved in 94 per cent and sphincterotomy was accomplished in 91.5 per cent. The bile ducts were demonstrated to be completely cleared of stones in 491 (81.6 per cent) of 602 patients. A mean number of 1.9 endoscopic retrograde cholangiopancreatography examinations per patient were necessary to achieve this result. Complications of endoscopic sphincterotomy, which were strictly defined, occurred in 10.5 per cent of patients although five patients had two complications (total complication rate 11.3 per cent). The 30-day mortality rate was 2.2 per cent, seven of 13 deaths (1.2 per cent) occurring as a direct result of sphincterotomy. There have been statistically significant improvements in bile duct clearance and complication rates with increasing experience of endoscopists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
