Abstract
Thirty mongrel dogs underwent 4000- or 5000-rad single treatment orthovoltage irradiation to the pelvis according to the nominal standard dose equation. Following a resting period of six months, 21 dogs were randomized to low anterior resection with either stapled or hand-sewn anastomoses. Anastomotic leaks were evaluated on clinical and radiographic grounds. The radiographic leak rate was 81 percent for sutured and 0 percent for stapled anastomoses. The clinical leak rate was 18 percent for sutured and 0 percent for stapled anastomoses. The difference between the 4000- and 5000-rad groups was not significant. The data suggest that late effects of irradiation do not preclude the safe construction of low anterior anastomoses, and that the circular stapling device is superior to hand-sewn techniques.
