Between January 1975 and December 1979, 71 patients over the age of 70 underwent attempted duodenoscopic sphincterotomy for stones in the common bile duct. Fifteen patients still had gall bladders in situ. Sphincterotomy was possible in 69 of the patients and in 65 of these duct clearance was achieved, giving an overall success rate of 92%. Failure to achieve sphincterotomy in two cases was due to substantial peripapillary diverticula. Duct clearance failed in four patients, mostly due to the size of the retained stones. The largest stone extracted was 24 mm diameter. There were no deaths but complications occurred in nine patients (13%); these were haemorrhage in four (requiring surgery in one), cholangitis in four (two of whom required surgical extraction of stones), and pancreatitis in one. The average duration of hospital stay in successful cases was 11 days (range three to 30). Clinical follow-up of 55 patients one to five years after sphincterotomy showed no evidence of stones or of stenosis of the sphincter. Duodenoscopic sphincterotomy is a major advance in the management of elderly patients with stones in the common bile duct.  相似文献

Among 100 consecutive patients who had removal or drainage of the gallbladder and exploration of the common bile duct for stones, there were no serious, immediate or late complications and there were no operative deaths. Ninety-six of the 100 patients had stones in the gallbladder, in the common duct, or in both, and 52 of these patients had one or more stones in the common duct. Ten patients died subsequently of unrelated causes. Six patients were lost to followup. Of the 84 patients whose present condition is known, 75 or 89 per cent have had a completely satisfactory result. Six more patients have minor residual symptoms, and for them the result has been classified as good. In three patients, the results were unsatisfactory. Cholangiograms taken before the removal of the T-tube showed residual stones in two patients. In each instance, the stone or stones have been subsequently passed and both patients are in excellent condition.  相似文献

We attempted to identify parasite DNA in the biliary stones of humans via PCR and DNA sequencing. Genomic DNA was isolated from each of 15 common bile duct (CBD) stones and 5 gallbladder (GB) stones. The patients who had the CBD stones suffered from cholangitis, and the patients with GB stones showed acute cholecystitis, respectively. The 28S and 18S rDNA genes were amplified successfully from 3 and/or 1 common bile duct stone samples, and then cloned and sequenced. The 28S and 18S rDNA sequences were highly conserved among isolates. Identity of the obtained 28S D1 rDNA with that of Clonorchis sinensis was higher than 97.6%, and identity of the 18S rDNA with that of other Ascarididae was 97.9%. Almost no intra-specific variations were detected in the 28S and 18S rDNA with the exception of a few nucleotide variations, i.e., substitution and deletion. These findings suggest that C. sinensis and Ascaris lumbricoides may be related with the biliary stone formation and development.  相似文献

A 54-year-old man with clinical and radiologic findings suggestive of pancreatic carcinoma had cytologic examination of bile drainage fluid specimens prepared by membrane filtration and cytocentrifugation. Examination showed clumps of malignant cells with features most consistent with a well-differentiated papillary neoplasm of bile duct origin, rather than a primary pancreatic carcinoma. Partial pancreatoduodenectomy with resection of the proximal common bile duct confirmed the presence of a small, well-differentiated but invasive papillary bile duct carcinoma. Pancreatic carcinoma and papillary carcinoma of the bile duct are anatomically and biologically different lesions that should be distinguished, when possible, by cytologic examination. In this case, surgical treatment was planned on the assumption that cytologic examination could distinguish a papillary carcinoma of the bile duct from the clinically suspected pancreatic adenocarcinoma.  相似文献
