Endoscopic retrieval method using a small grip-seal plastic bag for large colorectal resection specimens after endoscopic submucosal dissection

Abstract

Endoscopic submucosal dissection (ESD) has recently been developed for endoscopic treatment of colorectal polyps, enabling en bloc resection regardless of size and shape [1] [2]. However, it is often difficult to retrieve a large resected colorectal specimen after ESD without damage to the specimen by the anal sphincter muscle. Here, we report an effective technique to retrieve a large colorectal resected specimen after ESD without damage.
