Ultrasound-Guided Erector Spinae Block for Refractory Abdominal Pain Due to Acute on Chronic Pancreatitis.

Erector spinae blocks (ESBs) are a type of fascial pain block that has been safely used for various applications, including post-operative and post-trauma pain in several thoracic and abdominal surgeries. Pain related to an acute flare-up of chronic pancreatitis is usually challenging to control and impacts patient comfort and discharge planning. This case report describes an application of ESBs for the effective treatment of refractory abdominal pain associated with acute exacerbation of chronic pancreatitis. Application of ESB in the emergency room setting can potentially decrease hospital admission for this common condition and increase patient satisfaction.
