Abstract

Background

Compared with the piecemeal resection associated with endoscopic mucosal resection, endoscopic submucosal dissection (ESD) enables en bloc resection of larger lesions, allows for more accurate histological assessments, and has reduced recurrence rates. ESD is not widely performed in Western countries given increased technical difficulty, high complication rates, and long procedure times.

Aims

To evaluate the safety and efficacy of ESD in a single center in the USA.

Methods

A retrospective study on a prospectively collected database identified cases in which a single operator (IW) performed ESD at a tertiary referral center. Twenty cases were identified, nine in the upper digestive tract (four esophagus and five stomach) and 11 in the lower digestive tract (nine rectal and two sigmoid colon). Data regarding lesion location, pathology, method of ESD (composition/volume of lifting injection and resection method), post-procedure complications, and margin involvement were collected.

Results

En bloc resection was obtained in 14/20 patients (70 %). The average procedure time was 202 min in the esophagus, 148 min in the stomach, and 106 min for lower lesions. A major complication (perforation) occurred in 1/20 cases (5 %). Complete resection was obtained in 14/20 (70 %). R0 resection was obtained in 16/20 (80 %) cases.

Conclusions

The complication, en bloc resection, and complete resection rates of this study are similar to those found in large studies on ESD performed in Eastern settings. ESD is safe and efficacious for en bloc resections of pre-malignant and early-invasive lesions, and should be offered to patients with suitable lesions in Western settings.
