Objective Abdominal pain is the most common emergency department (ED) chief complaint, with many patients experiencing recurrent episodes due to non–life-threatening etiologies such as disorders of gut-brain interaction. This pilot study aimed to characterize patients with recurrent low-risk abdominal pain, focusing on pain severity, management, biopsychosocial factors, opioid use, and 30-day return visits. Methods This prospective, observational pilot study enrolled adult ED patients with recurrent abdominal pain at a single academic center between July 2022 and June 2023. Inclusion required at least one similar episode in the prior year with symptom resolution between episodes. Exclusions included unstable clinical status or high-risk conditions. Patient-reported outcomes, social determinants of health, and clinical data were collected. Primary outcomes included pain severity, opioid use, and 30-day return visit rates. Results A total of 101 participants were enrolled (mean age, 43.7 years; 65.3% female; 69.3% Black). Pain severity was high (triage pain score, 7.1±2.6). Frequent prior computed tomography imaging was noted in 56.4% of participants. Opioids were administered in 50 participants (49.5%), while Patient-Reported Outcomes Measurement Information System (PROMIS)-29 scores highlighted risks of anxiety (T-score, 56.0±11.1) and pain interference (T-score, 60.8±8.2). Return visits occurred in 11 participants (10.9%) within 30 days. Conclusion In this pilot study, patients with recurrent low-risk abdominal pain showed high symptom burden and healthcare utilization. Targeted interventions addressing biopsychosocial factors and improving pain management are needed to reduce ED revisits and improve outcomes.
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.
