摘要
Background and Objective: Endoscopic treatment of digestive tract diseases, such as early esophageal and gastric neoplasia, has become increasingly popular in recent years as an alternative to surgical procedures in the hope of providing an improved quality of life for these patients. However, one of the limitations of a conventional endoscopic mucosal resection, such as an aspiration mucosectomy and a strip biopsy, has been the size of the lesions to be resected. Both an aspiration mucosectomy and strip biopsy useful variants for removing flat lesions measuring less than 20 mm in maximal diameter. To overcome such limitations, we devised a double endoscopic intraluminal operation (DEILO), which enables us to resect mucosal lesions by using 2 fine endoscopes and monopolar shears. Methods: DEILO was performed on patients with esophageal and gastric lesions measuring up to 40 mm in diameter. This novel technique is characterized by the use of 2 endoscopes (one for lifting the lesion and the other for cutting the lesions) inserted into the esophagus or stomach through an overtube. A mucosal resection is then performed by dissecting the mucosal margin with newly developed monopolar shears, thereby separating the mucosa from the submucosa. Results: A total of 25 lesions in the esophagus (8 lesions) and stomach (17 lesions) were resected by DEILO. The sizes of the esophageal lesions ranged from 8 to 40 mm in diameter (mean, 21.1 mm) whereas gastric lesions ranged from 8 to 30 mm (mean, 13.3 mm) in diameter, and histopathologic examinations revealed the resection margin to be clear and without any tumor. No complications or instances of recurrence were observed in this series. Conclusions: DEILO is considered to be feasible for the mucosal resection of esophageal and gastric lesions measuring more than 10 mm in diameter without submucosal invasion, whereas conventional endoscopic mucosal resection is indicated for such lesions measuring less than 10 ram in size.
