Cholecystostoma: unusual evolution of a cholecystocutaneous fistula following percutaneous incision and drainage of perforated cholecystitis

Cholecystocutaneous fistulas (CCFs) are rare complications of gallbladder disease, wherein chronic inflammation leads the formation of an anomalous fistulous tract between the gallbladder and skin. Widespread availability of imaging modalities and timely access to surgical expertise has caused a marked decline in their incidence. Consequently, there is notable heterogeneity in management approaches to this disease entity, and guidance regarding the best, evidence-based treatment strategy is lacking. Most patients are definitively managed with cholecystectomy and en bloc excision of the adjoining fistula tract. However, there is no guidance on how to manage patients whose comorbidities preclude them from operative intervention. We provide the first report chronicling the stepwise development of a CCF in a 75-year-old woman, complete with pictorial documentation of its evolution. Furthermore, we present the inaugural account of a practical, safe approach to the long-term conservative management of CCFs in patients in whom surgical or endoscopic intervention is prohibitive.
