Iatrogenic Cushing's From Celiac Plexus Blocks for Chronic Pancreatitis: A Case Report.

Chronic pancreatitis and pancreatic malignancies can result in chronic pain that is difficult to treat with traditional regimens. Various pain management strategies have been implemented to improve the quality of life for patients with these conditions, but these strategies are limited by their efficacy and side effects, including opiate dependence. Celiac plexus blocks (CPB) and celiac plexus neurolysis (CPN) were implemented to decrease opiate dependency and treat chronic pain for pancreatitis and pancreatic malignancy. Numerous approaches are used to facilitate CPB/CPN, including percutaneous, surgical, and endoscopic, guided as computerized tomography (CT), fluoroscopy, ultrasound (US), or endoscopic ultrasound (EUS) techniques. EUS is the latest development in CPB/CPN and the least commonly utilized method; however, it is highly efficacious and associated with minimal complications and/or risks. With endoscopic CPB/CPN, overall mortality improves. Despite the various complications associated with other techniques, no case report or current literature has documented the development of iatrogenic Cushing's disease from the use of steroids during CPB via any approach. Herein, we report the first case of iatrogenic Cushing's disease from CPB in the treatment of chronic pancreatitis. Future studies are warranted to examine the agents used in the chemical destruction for CPB/CPN, to avoid complications such as this.
