| pubmed-article:7061607 | pubmed:abstractText | External biliary drainage, the "routine" manner of terminating surgery on the common bile duct, should now become almost obsolete as new methods for operation and exploration during surgery are perfected. A review of cases receiving biliary surgery over a period of 20 years showed that external biliary drainage was conducted in only 4 p. cent of operations on the common bile duct (excluding biliodigestive anastomoses). External biliary drainage should be employed only after due reflection : trans-cystic drainage, the "minor" form, will be indicated less and less as investigational methods during operation develop, while Kehr's drain, the "major" form, will occupy a limited but necessary place in certain cases, primarily in angiocholitis. | lld:pubmed |
