  • feasibility of single port laparoscopic surgery for Sigmoid Colon and rectal cancers and preoperative assessment of operative difficulty
    Journal of Gastrointestinal Surgery, 2014
    Co-Authors: Atsushi Hamabe, Ichiro Takemasa, Mitsugu Sekimoto, Masataka Ikeda, Tsunekazu Mizushima, Hirofumi Yamamoto, Yuichiro Doki, Mamoru Uemura, Junichi Nishimura, Masaki Mori
    Abstract:

    Purpose Single-port laparoscopic surgery is more difficult for Sigmoid Colon and rectal cancers than for right-sided Colon cancer. We sought to analyze the feasibility of this procedure for Sigmoid Colon and rectal cancers and to estimate its difficulty.

  • transumbilical single incision laparoscopic surgery for Sigmoid Colon cancer
    Surgical Endoscopy and Other Interventional Techniques, 2010
    Co-Authors: Ichiro Takemasa, Mitsugu Sekimoto, Masataka Ikeda, Tsunekazu Mizushima, Hirofumi Yamamoto, Yuichiro Doki, Masaki Mori
    Abstract:

    Background Transumbilical single-incision laparoscopic surgery is an emerging concept that could offer excellent cosmetic results [1]. The authors describe an index case of curatively intended resection of early-stage Sigmoid Colon cancer using this technique [2, 3].

  • differences between features of adenoma in the rectum versus Sigmoid Colon
    The American Journal of Gastroenterology, 2000
    Co-Authors: Yoichi Ikeda, Masaki Mori, Kazunari Akagi, Akinori Iwashita, Yukiaki Haraguchi, Yoshihiko Maehara, Keizo Sugimachi
    Abstract:

    Abstract OBJECTIVE: Although the prevalence of cancer in the rectoSigmoid is high compared with that in the more proximal Colon, the features of cancer developing from an adenoma have yet to be eluciated. The aim of this study is to examine the clinicopathological relationship between cancer and adenoma in the rectoSigmoid. METHODS: A total of 340 adenomas located in the rectoSigmoid in 255 patients were retrospectively examined regarding such clinicopathological factors as location and the grade of dysplasia. RESULTS: The prevalence of adenoma was 102 in the rectum and 238 in the Sigmoid Colon, respectively, whereas the prevalence of adenoma with high-grade dysplasia was 39 in the rectum and 48 in the Sigmoid Colon, respectively. This prevalence of adenoma with high-grade dysplasia was thus significantly higher in the rectum than in the Sigmoid Colon ( p CONCLUSIONS: These findings suggest the possibility of different types of cancer development between adenoma of the rectum and Sigmoid Colon.
