INITIAL EXPERIENCE OF ENDOSCOPIC SUBMUCOSAL DISSECTION IN BRAZIL TO TREAT EARLY GASTRIC AND ESOPHAGHEAL CANCER: a multi-institutional analysis
Objective This study aimed to evaluate the feasibility and clinicopathological characteristics of early gastric and esophageal cancers treated with endoscopic submucosal dissection (ESD) at five centers in Brazil. Methods Five centers in Brazil reported their initial experience with ESD. The cases reported had already been collected by each center before pooled analysis. Results Were resected 62 gastric lesions; 52(83,8%) of the gastric lesions were well-differentiated adenocarcinoma, 31(50%) from the antrum, 24 (38.7%) type IIa. 51 (82.2%) lesions had en-block resection with three showing lateral margin compromise. Concerning invasion, 25 (40.3%) tumors were M1. Mean tumor diameter was 18.9 mm (range, 0.6-5.0 cm) and mean procedure duration was 119.45 minutes. Gastric perforation occurred in three (4.8%) patients. Mean follow-up duration was 11.3 months, with two local recurrences and one death from pneumonia Seven months after treatment. Of the 16 esophageal lesions resected, 14 (87.4%) were squamous cell carcinoma, 10 (62.5%) were located proximally and 8 (50.0%) type IIa. Mean tumor diameter was 23.8 mm (range, 6-60 mm). Thirteen (81.2%) lesions had en-block resection with five cases of lateral margin compromise. Eight (50.0%) lesions were M1. Mean procedure duration was 78 minutes (range, 20-150 min). Complications included pneumomediastinum in two (12.5%) patients and stenosis in one (6.2%). Mean duration of follow-up was 8.6 months, with no local recurrence despite the presence of lateral margin compromise. Conclusion Different centers in Brazil feasibly perform ESD with a high success rate.
