Abstract
Background: Hypercontractile esophagus (HE) is a disorder of increased esophageal body contractile strength on high‐resolution esophageal manometry (HREM). Compartmentalized pressurization (CP) is a pattern with an isobaric contour of >30 mmHg extending from the contractile front to the lower esophageal sphincter on HREM. The relevance of CP to HE has yet to be explored.Methods: A retrospective review was performed on 830 HREM studies of patients to identify HE. HE patients' CP status and symptoms by Eckardt score (ES) were reviewed. Diagnoses were made using Chicago Classification (CC) v4.0.Key Results: Forty‐seven patients (5.6%) were identified as having HE by CCv3, 30 (3.6%) of which had HE by CCv4. 11/30 HE patients had CP, and 19/30 did not. CP was associated with chronic opioid use (36.4% vs. 5.3% p = 0.047). Presenting ES was greater for HE patients with CP (7 vs. 4). Seven HE patients with CP and 11 without CP were managed medically. ES after medical therapy was higher in HE patients with CP compared to those without CP (9 vs. 0). No HE patients with CP responded to medical therapy. Kaplan–Meier analysis demonstrated significance of this association over time. 83% of all HE patients had all‐cause symptom remission.Conclusions & Inferences: HE patients with CP are associated with a higher presenting ES. HE patients with CP do not respond to medical therapy, while HE patients without CP frequently do respond. CP in HE may have prognostic value in determination of treatment strategy for patients with HE.
