[Practical approach to tumoral perforations of cancers of the colon. Apropos of 7 cases].

In 4 to 5% of cases, the cancer of large bowel is presented with a perforation in situ. The mortality rate in these conditions is high, and it is evaluated in the literature between 40 to 50% of cases. The authors present their experience with 7 consecutive patients, operated for this complication. In all cases, the tumour is excised: in 6 patients, terminal colostomy is realised while one patient only had a direct resection anastomosis. No per-operative mortality, was noted, and in four patients retauration of intestinal tract is realised, within 3 to 6 months latter. In our experience, the perforated tumour does not appear as a factor of immediate gravity.
