IS CLEAN DISSECTION OF CALOT'S TRIANGLE NECESSARY IN CHOLECYSTECTOMIES?

In this study when patients were followed up for post-operative symptoms, it was seen that the incidence of narrowing of lumen of the common bile duct was more in cases where the operation was done by retrograde cholecystectomy with clean dissection of Calot's triangle. Though this was a coincidental finding, it raises a doubt whether the narrowing is a result of impairment of blood supply to the common bile duct, which may result from clean dissection and display of Calot's triangle area. The above dissection removes the fascial layer over the common bile duct and is likely to result in damage to end-arteries piercing through it to the common bile duct. This conjecture requires further study in a larger series.
