Common bile duct dynamics calculous and acalculous gallbladder disease before and after cholecystectomy

ABSTRACT

This work was carried out on 33 patients with chronic cholecystitis divided into two groups Group 1 included 20 patients with calculus cholecystitis and group 2 included 13 patients with acalculus cholecystitis. The diagnosis was established by oral cholecystography and ultrasonography. The common bile duct [CBD] diameter was measured preoperatively. All patients of group 1 and group 2 were submitted to cholecystectomy. Preoperative measurements of CBD pressure and flow before and after removal of the gall bladder were done. Measurements of CBD diameter, pressure and flow were repeated on the 4th and 10th days postoperatively. The results showed no significant difference in the CBD diameter, pressure and flow between the two groups. Following removal of the gall bladder, there was an immediate drop of both pressure and flow in both groups. Postoperative studies showed nonsignificant change in the CBD diameter in both groups. CBD pressure and flow readings returned to their preoperative values by the 10th postoperative day
