We conducted a systematic review to assess the efficacy of preoperative, topical ketamine application for preventing postoperative sore throat.

[Two cases of recurrence at anastomosis site with leakage after operation for rectal cancer].

We report two cases of recurrence at an anastomosis site with leakage after operation for rectal cancer. In these cases, we thought that an implantation on leakage sites should be occurring by remaining stool with cancer cell. Colorectal cancer with ileus owing to obstacle by tumor, such as our cases, has a high risk of leakage at the anastomosis site and developed a complication that increased the risk of local recurrence.
