| Popis: | Background and study aims Endoscopic submucosal dissection (ESD) is widely used as a treatment modality for gastric mucosal neoplasia. While proton pump inhibitors (PPIs) have been used for the control of artificial ulcers created by ESD (ESD-ulcers), complete healing of the ulcers is not always achieved in all the cases. The purpose of this study was to identify the clinical factors that are predictive of refractory ESD-ulcers. Patients and methods We recruited 90 patients with 102 artificial ulcers that formed after the patients underwent ESD for gastric tumours. All the patients received a 20-mg capsule of esomeprazole daily until the 56th day after ESD, and underwent endoscopy at 1, 4, 6 and 8 weeks after the ESD. We analyzed the clinical factors that were associated with the complete healing at 8 weeks after the ESD (CH-8w). The ulcers in the scar stage were defined as the complete healing in this study. Results Of the 102 ESD-ulcers, 16.7% failed to show complete healing after the 8 weeks of PPI therapy. Univariate analysis identified the percent reduction of the ulcer size at 4 weeks after ESD (PR-4w) as being significantly associated with CH-8w. Multivariate analysis identified ulcer location in the lower-third of the stomach and PR-4w > 95% as being independently correlated with the CH-8w (odds ratio = 4.86 and 7.89, respectively). Analysis of the area under the receiver operating characteristic (AUROC) curve demonstrated that the AUROC curve of PR-4w for predicting the CH-8w was 0.78. Conclusion Based on the results of our study, endoscopic observation at 4 weeks after ESD would help in the early identification of refractory ESD-ulcers. |
