"Mother-baby" biliary endoscopy: the University of Chicago experience.
OBJECTIVE: The "mother-baby" technique of peroral cholangioscopy is a relatively recent development in biliary endoscopy and permits direct visualization of the biliary tree. This paper presents the experience of one institution with this new technique. METHODS: We used the Olympus mother-baby endoscopy system at the University of Chicago and at one of its affiliated hospitals to examine and treat selected lesions in the biliary tree that had eluded successful diagnosis or treatment by standard means. In addition, we used the baby endoscope alone through surgically created percutaneous tracts to treat selected patients with retained stones. RESULTS: From July 1990 to June 1993, peroral cholangioscopy was performed 18 times in 12 patients at the University of Chicago and affiliated hospitals. The baby endoscope was successfully passed into the bile duct in 15 of 18 cases (83.3%). Additionally, the baby endoscope alone was used through a T-tube or cholecystostomy tract 10 times in six patients. Complications occurred in two patients and were minor; there were no fatalities. With refinement of technique, successful passage of the baby endoscope was accomplished in 100% of patients undergoing peroral cholangioscopy. CONCLUSIONS: Direct visualization of the biliary tree with the ability to sample (brush, biopsy) or treat (basket removal, electrohydraulic or laser lithotripsy) lesions significantly aided in the care of all patients in whom the baby endoscope was successfully passed by providing the correct diagnosis and, when appropriate, by allowing definitive treatment of lesions. The eventual role of this technique in the current cost-conscious climate is unclear, but at present it should be limited to selected referral centers.[1]References
