RESUMO
Objective To Investigate the safety and clinical significance of self-made wrapper tube assisted endoscopic mucosal resection for upper esophageal mucosal endometriosis.Methods A total of 53 patients with upper esophageal mucosal endometriosis and the corresponding symptoms, which was confirmed by endoscopy and pathology, underwent endoscopic treatment.The endoscope was inserted into the esophagus together with wrapper tube.Then the endoscope was retreated into the wrapper tube and pulled back together with the tube.When the tip of the wrapper tube reached at the oral side of the lesion, it was fixed, and submucosal resection was performed.All patients were followed up to 6 months.Results All lesions were completely resected, which was achieved by one session in 45 patients, by two in 5, and by three in 3 other patients, with a mean procedure time at 6.5 minutes (4.5-7.5).Symptoms were relieved in 43 patients (81.1%) at 3 months after the procedure, and in 45 patients (85%) at 6 months.No local recurrence was observed under endoscopy and biopsy.No complications including esophageal stenosis, perforation or cardiopulmonary accidence were recorded. Conclusion For upper esophageal mucosal endometriosis presented with local symptoms, wrapper tube assisted endoscopic mucosal resection is safe, less invasive, easy to manipulate and effective.
