Abstract

Abdominal pain is one of the most common presenting chief complaints in the emergency department. Erector spinae plane block (ESPB) is an ultrasound-guided nerve block with proven effectiveness in treating visceral and somatic abdominal pain. Despite the increasing popularity of ESPB, its role in the management of nonsurgical abdominal pain has not yet been characterized. Our scoping review aims to synthesize current knowledge on the safety and efficacy of ESPB in the management of patients experiencing intractable, nonsurgical abdominal pain. We searched PubMed and Scopus to evaluate the existing literature on ESPB for nonsurgical abdominal pain. A total of 14 journal articles were included: 12 case-based studies, one systematic review, and one narrative review. All cases described the successful use of ESPB in treating abdominal pain refractory to oral or intravenous analgesic medications, and no complications were reported in any cases. This scoping review provides support for the use of ESPB to manage intractable, nonsurgical abdominal pain. ESPB has demonstrated efficacy in alleviating various conditions such as functional abdominal pain, renal colic, pancreatitis, herpetic pain, and cancer-related pain. Theoretical risks such as pneumothorax, bleeding, and infection are possible, although the studies reviewed did not report such complications.
