Case and Management Considerations of Low-Grade Cystic Duct Stump Dysplasia after Laparoscopic Cholecystectomy.

Abstract

Cholecystectomies have become one of the more commonly practiced procedures. As a result, there has been a rise in neoplastic changes in excised specimens. Due to this, surgeons must be prepared to manage possible malignancy after resecting what was previously thought to be a benign gallbladder. While management for high-grade dysplasia has been more clearly laid out in literature, data on management of low-grade dysplasia are limited. Here, we report a novel case of a 46-year-old woman with an incidental low-grade dysplasia of the cystic duct stump after a laparoscopic cholecystectomy for biliary colic. The decision was made to excise the remaining stump without further surveillance postoperatively given benign pathology findings. More documented cases and their management and ultimately longitudinal cohort studies will help facilitate the creation of guidelines for managing this particular pathology.
