Why every colorectal surgeon should learn endoluminal surgery

Endoscopic submucosal dissection (ESD) is an advanced therapeutic technique used to remove non-malignant polyps (NMP) and early cancers. Benefits include reducing unnecessary colectomies, cost, and morbidity of NMP treatment. Other roles for ESD and associated skills are likely to expand in the future, including in the non-operative management of rectal cancer. The learning curve is feasible with established training methods. Colorectal surgeons already perform routine endoscopy and manage endoscopic complications and endoscopically incurable lesions- endoluminal surgery (ELS) is a natural extension of this. Expanding technologies will only improve our ability to resect these lesions endoluminally moving forward. Collaboration with gastroenterologists and acquiring, rather than abandoning, this skillset is important and obtainable. Colorectal surgeons have the tools and professional duty to stay at the forefront of managing colorectal diseases endoscopically. Despite substantial barriers to mastering ELS, the value to our patients and profession means all colorectal surgeons should learn these techniques.
