the patients were divided into a group irradiated at the anastomosis site on the anal side and the group not irradiated in the same region. The change over time in the rate of patients who could eat a normal diet in these groups is shown in figure 3. About one third of patients in both groups were able to eat a normal diet within postoperative six moths; however, in the group without irradiation of the anastomotic region, sround 90% of patients could eat a normal diet from one and a half years postoperatively. In the group where an anastomic region was irradiated, the rate of normal diet intake was low from postoperative six months to two and half years: and about 60% of patients could eat a normal diet from two and a half years postoperatively. However, all patients in both groups could eata normal diet more than three years postoperatively. In other words, it will take three years until they can eat a normal diet. Meanwhile, the patients underwent frequentbougie for stenosis of anal side anastomosis. When the anastomotic area was in the radiation field, half of all cases underwent an average of 3.5 expansion bougies of the anastomotic area. On the other hand, 27% of cases without irradiation to the anastomotic area underwent an average of 2.4 bougie. Overall, 36% of cases showed a symptom of anastomotic stenosis. By the maneuver of the free jejunum autograft at Kurume University at that time, the feeding situation was also not satisfactory.
