Abstract
Introduction: Post-endoscopic submucosal dissection (ESD) coagulation syndrome (PECS) is defined as abdominal pain with inflammatory responses, requiring careful differentiation from delayed perforation (DP). This study aimed to evaluate clinical and biochemical characteristics associated with PECS and DP following ESD and to develop a scoring system for predicting PECS.
Methods: We retrospectively analyzed 318 consecutive patients who underwent colorectal ESD at our institution between January 2022 and June 2024. Patients were classified into three groups: PECS (n = 32), DP (n = 7), and no-PECS/no-DP (NPD) (n = 279). Multivariate analysis was performed to identify predictors of PECS for clinical factors and values such as C-reactive protein (CRP), white blood cell (WBC) count, and body temperature. Based on significant predictors, we constructed a five-variable PECS-predictive scoring system (FPSS) for early post-procedure prediction of PECS.
Results: Among 318 patients, the incidence of PECS and DP was 10.1% and 2.2%, respectively. DP cases demonstrated greater CRP elevation (p < 0.001) and higher leukocytosis (p = 0.011) compared with PECS, while PECS cases showed significantly higher WBC (p < 0.001) and CRP (p < 0.001) than the NPD group. Multivariate analysis identified five independent predictors of PECS: right colon (odds ratio [OR] = 3.54; p = 0.004), female gender (OR = 2.10; p = 0.018), body temperature ≥37.6°C (OR = 16.70; p < 0.001), WBC >8,000/µL on day 1 (OR = 13.78; p < 0.001), and lesion size >24 mm (OR = 3.03; p = 0.003). The FPSS (range 0-9) achieved an area under the receiver operating characteristic curve of 0.881, with high negative predictive value (97.4%).
Conclusion: The characteristics of PECS were clarified in comparison with NPD and DP, and the newly developed FPSS demonstrated excellent diagnostic performance of PECS.
期刊介绍：
''Digestion'' concentrates on clinical research reports: in addition to editorials and reviews, the journal features sections on Stomach/Esophagus, Bowel, Neuro-Gastroenterology, Liver/Bile, Pancreas, Metabolism/Nutrition and Gastrointestinal Oncology. Papers cover physiology in humans, metabolic studies and clinical work on the etiology, diagnosis, and therapy of human diseases. It is thus especially cut out for gastroenterologists employed in hospitals and outpatient units. Moreover, the journal''s coverage of studies on the metabolism and effects of therapeutic drugs carries considerable value for clinicians and investigators beyond the immediate field of gastroenterology.
