“…Resection of a lesion is critical for making a histopathological diagnosis and the only method currently available for larger tumors, 3 cm or more in diameter, in the right colon is piecemeal removal with snare wire strangulations (13)(14)(15). Laparoscopic surgery combined with lymph node dissection has been reported to be most suitable for the treatment of larger superficial tumors of the large bowel, including early large bowel cancer (16)(17)(18)(19).…”

“…We have already reported various experimental and clinical results on our large bowel EMR technique using two-channel to three-channel outer tubes and needle knives (13)(14)(15). However, we found that it was often difficult to accurately manipulate the forceps to treat a target lesion in the right colon because this region is about 150 cm from the anus.…”

In the present study, we experimentally examined the feasibility of two-colonoscope surgery using two types of forceps to achieve safe, reliable, and complete endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) of large superficial tumors in the right colon. It was confirmed at all experimental sessions that the two pairs of forceps intersected with each other over a wide angle of at least 90˚ in the cecum, and that the tips of the forceps could be moved by at least 180˚ in the longitudinal and horizontal directions. In another experiment, a piece of tissue measuring 3x3 cm or larger could be safely resected from a chicken thigh as the pseudo-tumor. Based on these results, twocolonoscope surgery is considered clinically promising as a next-generation EMR/ESD technique for safe, reliable, and complete resection of superficial tumors of the right colon measuring 3 cm or more in diameter.

Submucosal injection is the most important procedure for the safe performance of endoscopic mucosal resection in the large intestine while avoiding the risk of perforation. We used dilute sodium hyaluronate containing Bosmin and achieved safe piecemeal resection of large superficial tumors in the right colon in two patients. Piecemeal snare resection is considered to be acceptable if all the tissue pieces can be collected for histopathological diagnosis.

Novel Three-Channel and Three-Slit Stiffening Tube for Total Colonoscopy

Abstract: The TCTS stiffening tube was as easy to use as the standard stiffening tube, and is considered to be both safe and useful.
