[A Case of Curatively Resected Rectosigmoid Colon Cancer That Invaded the Urinary Bladder after Neoadjuvant Chemotherapy].

The patient was a 65-year-old man. His complaints included bloody stools and pain on urination. A detailed examination suggested vesical wall invasion, leading to a diagnosis of rectosigmoid cancer(cT4b, N+, M0).

[Usefulness of Laparoscopic Stoma Creation for Unresectable Colorectal Cancer].

Laparoscopic stoma creation enables good visualization of viscera within the abdominal cavity to ensure adequate mobilization of the large intestine. Laparoscopic stoma creation/construction was indicated and performed at our hospital in 7 patients who were diagnosed with unresectable colorectal cancer between July 2015 and May 2017. Duringthe ileostomy procedure, we made a skin incision at the stoma site and performed a single-incision(3-port)laparoscopic surgery.

[A Case of Adult Invagination Caused by Rectal Cancer].

An 87-year-old man visited our hospital with a chief complaint of melena. Invagination caused by rectal cancer or sigmoid colon cancer was suspected as a result of physical and radiological examinations. Since there were no subjective symptoms, laparoscopic surgery was planned electively.

Impact of the reduction of environmental and equipment contamination on vancomycin-resistant enterococcus rates.

More than 1,500 perirectal swab cultures and 552 environmental and equipment cultures were collected during the study period. Enterococcus faecium was the most frequent species isolated, being responsible for 71% of the positive cultures. Fifty infections were documented, with bloodstream infections (18, 36%) being the most frequent, followed by urinary tract infection (15, 30%).

[Induction of immunogenic variant of a murine fibrosarcoma].

Immunogenic variant was induced from the methylcholanthrene induced fibrosarcoma (MCA-F) by in vitro treatment with the mutagen 1-methyl-3-nitro-1-nitrosoguanidine (MNNG). D-10 tumor cell which was cloned from MNNG treated MCA-F tumor cell was rejected by normal syngeneic C3H-HeJ mice but not by 650 rad irradiated immunosuppressed mice. Host which had rejected D-10 tumor growth, rejected parental MCA-F tumor cells.
