Prognosis of rectal carcinoma patients operated with a stapling device: a review of 150 cases.

A new type of suturing stapler was designed and has been tried in animal experiments and in clinical application, showing it to be an efficient instrument to use in colorectal surgery. During the period September 1977 to 1982, 150 cases of carcinoma of the rectum were treated by tumor resection and colorectal anastomosis with a suturing stapler device. The 1-, 2-, 3-, and 4-year survival rates were 94.0, 83.8, 75.7, and 62.5%, respectively. For those patients with liver metastasis, operation including resection of the primary and, if possible, surgical removal of solitary metastatic nodules, was recommended.
