Removal of large colorectal lesions resected by endoscopic submucosal dissection using a laparoscopic bag.

Colorectal endoscopic submucosal dissection (ESD) has become the standard of care for large superficial colorectal neoplasms, and allows en bloc resection of very large lesions [1]. The first goal of this technique is en bloc and R0 resection of large colorectal lesions to allow good pathological examination and determination of whether the endoscopic resection was curative. Such a conclusion is only possible if the lesion is resected en bloc without damaging the specimen. For lesions of standard size (2–6cm), a basket net is most frequently used to retrieve the specimen. However, the tools available to retrieve larger lesions are often too small, making retrieval of the specimen without damage challenging. Recently, a Japanese team reported an innovative technique known as tumor extraction by defecation (TED) [2]. At the end of ESD performed under conscious sedation, spontaneous extraction by defecation controlled by the patient E-Videos
