Ultrasonographic evaluation of common duct diameter in pre and post cholecystectomy patients.

ABSTRACT

Thirty four patients with gall bladder disease and normal common duct were investigated prospectively by ultrasonography just before cholecystectomy and at periodic intervals of 1 months, 2 months, 3 months and once in 4-6 months after cholecystectomy. The pre and post cholecystectomy common duct diameters were measured at each visit and compared with each other to determine the statistical significance. No significant change (p > 0.05) occurred in common duct diameter following cholecystectomy.
