High proficiency of esophageal endoscopic submucosal dissection with a "tunnel plus clip traction" strategy: a large french multicentric study

Résumé

Background Esophageal endoscopic submucosal dissection (ESD) is the gold standard for the treatment of precancerous lesions or superficial esophageal cancers. This procedure is currently performed by expert endoscopists only, and poorly standardized. We aimed to assess the technical results and outcomes of a "tunnel + clip" strategy for esophageal ESD procedures performed by less experienced operators for the treatment of superficial neoplasms. Methods All consecutive esophageal ESDs performed with the "tunnel + clip" technique for patients with early esophageal cancer in 3 centers were enrolled. Procedural characteristics, clinical outcomes, and complications were recorded. Results Among 195 esophageal ESD procedures performed, early adenocarcinomas or high-grade dysplasia complicating Barrett's esophagus were predominant (132/195, 67.7%) compared with early squamous cell carcinomas (63/195, 32.3%). The en bloc, R0 and curative resection rates were 100% (195/195), 78.5% (153/195) and 67.2% (131/195), respectively. The mean rate of ESD was 29.7 mm(2)/min. One (0.5%) perprocedural perforation and 7 (3.6%) postprocedural bleedings occurred, all managed endoscopically. No delayed perforation occurred. Overall, 31 patients (31/195; 15.9%) of patients developed stenosis. Conclusions The "tunnel + clip" strategy is safe, and allows to achieve high en bloc, R0 and curative resection rates. This standardized procedure could be used by physicians with little experience and might help spreading esophageal ESD in Western countries.
