AIM: To investigate post endoscopic submucosal dissection electrocoagulation syndrome (PEECS) of the esophagus. METHODS: We analyzed 55 consecutive cases with esophageal endoscopic submucosal dissection for superficial esophageal squamous neoplasms at a tertiary referral hospital in South Korea. Esophageal PEECS was defined as "mild" meeting one of the following criteria without any obvious perforation: fever (≥ 37.8°C), leukocytosis (> 10800 cells/μl), or regional chest pain more than 5/10 points as rated on a numeric pain intensity scale. The grade of PEECS was determined as "severe" when meet two or more of above criteria. RESULTS: We included 51 cases without obvious complications in the analysis. The incidence of mild and severe esophageal PEECS was 47.1% and 17.6%, respectively. Risk factor analysis revealed that resected area, procedure time, and muscle layer exposure were significantly associated with PEECS. In multivariate analysis, a resected area larger than 6.0 cm2 (OR = 4.995, 95%CI: 1.110-22.489, P = 0.036) and muscle layer exposure (OR = 5.661, 95%CI: 1.422-22.534, P = 0.014) were independent predictors of esophageal PEECS. All patients with PEECS had favorable outcomes with conservative management approaches, such as intravenous hydration or antibiotics. CONCLUSION: Clinicians should consider the possibility of esophageal PEECS when the resected area exceeds 6.0 cm2 or when the muscle layer exposure is noted.
