Background: Recently, combination S-1 and CDDP chemotherapy is considered as a standard regimen for unresectable or recurrent gastric cancer. Second-line chemotherapy is reportedly important to improve survival, and combination of Irinotecan and Mitomycin C as second-line chemotherapy has proven effective in phase II study of JCOG 0109-DI.

Purpose: We assessed the efficacy of combination of Irinotecan and Mitomycin C as second-line chemotherapy for unresectable and recurrent gastric cancer.

Background: Endoscopic mucosal resection with a cap-fitted panendoscope (EMRC) such as a soft prelooped hood is a useful, effective, and safe technique. One problem with this method is that the lesion cannot always be maintained in the center of the cap because the procedure is performed blindly after aspiration.

Objective: We developed a 2-channel prelooped hood that facilitates EMRC while simultaneously allowing both grip of the center in the lesion and irrigation of the aspiration site and evaluated the usefulness of this end hood for early gastric cancer.

Purpose: Premedication with glucagon or hyoscyamine is reported to be effective in reducing colonic spasm. However, these drugs can be associated with unfavorable events. This prospective study was designed to compare the effects of premedication with glucagon with those of scopolamine butylbromide on cardiopulmonary parameters, intubation time, and patient discomfort in unsedated patients undergoing diagnostic colonoscopy.

Background/aims: Since endoscopic en bloc resection of large and sessile tumors is technically difficult, endoscopic en bloc piecemeal mucosal resection (EPMR) is usually chosen for resection of such tumors. Tumors resected by EPMR are, however, difficult to evaluate histologically. The aim of this study was to evaluate the safety and effectiveness of EPMR.

Objectives: Application of a new variable stiffness colonoscope (VSC) is expected to control loop formation and to lessen patient discomfort. The aim of this prospective study was to compare the efficacy of VSC with a conventional colonoscope (CC) in unsedated colonoscopy, based on the experience of examiners.

Methods: Four-hundred sixty-seven patients were randomly assigned to undergo colonoscopy with either VSC or CC by an endoscopist, including experienced and less-experienced examiners.
