[Dehiscence of anastomosis in surgery of the colon. Causes and prevention].

150 operations on the large intestine performed in 1976-81 are presented with the percentage of dehiscences following surgery. In considering the problem of fistulas arising on the colonic sutures, the more frequent aetiopathogenetic factors are examined. The percentages reported are compared with those produced by the best medical schools. Curves recommended in recent literature are also reported.
