Abstract

Background

The improved submucosal tunneling endoscopic resection (STER) with slant tunnel was created by our group innovatively for submucosal tumors (SMTs) in the proximal esophagus. This study aimed to provide the preliminary results of the improved STER from our center.

Methods

The key step of the improved STER is establishing a slant tunnel instead of a vertical tunnel. After a longitudinal incision was made proximally in the inclined top to the tumor, a submucosal tunnel was established from the incision to the SMT slantingly. 28 patients undergoing STER with slant tunnel were enrolled in the retrospective study. Clinical results including en bloc resection, curative resection and complication were collected.

Results

All the submucous tumors located at proximal esophagus originated from muscularis propria were successfully resected by the innovative STER. Tumor size ranged from 18-43 mm, with 96.4% (27/28) en bloc resection rate and 92.9% (26/28) curative rate. Three patients suffered complication, 1 patient with mild pleural effusion and another 2 patients with fever for one day. All of the complications were cured by conservative treatment.

Conclusions

STER with slant tunnel seems to provide an optional treatment for tumors in proximal esophagus.
