Technique of intraluminal biliary ultrasonography during laparoscopic cholecystectomy.

Journal Article (Journal Article)

Intraluminal ultrasonography of the common duct was performed in nine patients undergoing laparoscopic cholecystectomy, using a system comprising a 20-MHz crystal in a 95-cm, blunt-tipped 6F sheath, mechanically rotated at 1,800 rpm. The probe was introduced through an incision in the cystic duct and passed into the duodenum. When the catheter was withdrawn, excellent visualization of the common and cystic ducts and lower end of the common hepatic duct was achieved. In seven patients, the biliary tree was normal. A small calculus was discovered in the common duct in one patient. This stone was not seen on a subsequent cholangiogram and was subsequently retrieved. An additional patient had mucus or sludge noted in the duct, which cast no acoustic shadow and thus was distinguished from calculi. The technique was fast, efficient, and easy to perform in this small group of patients and holds promise for screening the common duct pathology during laparoscopic cholecystectomy.
