Background and Objective The master and slave transluminal endoscopic robot and other flexible endoscopy platforms are designed primarily for the remote control of forceps, with manipulation of the endoscope itself still dependent on conventional techniques. We have developed an endoscopic therapeutic robot system (ETRS) that provides complete remote control of all forceps and endoscope operations. Method We carried out endoscopic submucosal dissection (ESD) in porcine stomachs using the ETRS. All procedures were completed with the endoscopist seated at the console the entire time. Results Total en bloc resection was achieved in all 7 cases with no complications. The mean total procedure time was 36.14 ± 14.98 min, the mean size of the resected specimen was 3.39 ± 0.66 cm × 3.03 ± 0.63 cm, and the mean dissection time was 14.91 ± 8.61 min. Conclusion We successfully used the ETRS to perform completely remote-controlled ESD in porcine stomachs.

In the article titled "Development of a Novel Gastrointestinal Endoscopic Robot Enabling Complete Remote Control of All Operations: Endoscopic Therapeutic Robot System (ETRS)" [1], there was an error in Supplementary Materials (available here), whereby the second supplementary video was omitted. This error occurred during the production process. The correct supplementary materials are as follows. Supplementary Materials Video 1: the functions and method of operation of the ETRS. Video 2: the performance of ESD in a porcine stomach using the ETRS. The video displays four divided images; these show the operation, as captured by the 2 robot operation cameras: console operation in close-up (right lower), console operation from distance (right upper), commentary of operation (left lower), and the endoscope monitor (left upper).
