Of the malignant tumors in our country, colorectal cancer has the highest incidence. Currently, the radical treatment of cancer is mainly performed with surgical resection, and the demand for minimum invasive, laparoscopic surgery has been increasing. Radical operation for colorectal cancer is of course the most important; however, the number of laparoscopic surgery has increased sharply from the recent improvements in technology and good results of multiple clinical trials (Fig. 1). In our hospital, we have actively introduced laparoscopic surgery from the opening of the hospital and have improved the technology.
In addition, regarding a permanent stoma in radical surgery for rectal cancer, we have introduced a technique reconstructed by anastomotic suturing of colon and anus (intersphincteric resection: ISR) that remained radical by resecting a part of the internal anal sphincter since the time of opening of the hospital, and have avoided permanent stoma in many cases.
At now, the ratio of having stoma due to rectal cancer has been about 10%.
For metastatic lesions of colorectal cancer, it is important for us to have comprehensive treatment capability in cooperation with the departments of Hepato-Biliary-Pancreatic Surgery, Respiratory Surgery, and Radiation Therapy. We make efforts to provide the latest, optimal treatment by collaborating with each department.
