[Treatment strategy and results in primary inoperable rectal cancer]

The authors report their experience with laparotomy in patients with rectal carcinoma to identify those patients with locally non-resectable primary cancer of the rectum who may be treated initially by high-dose radiotherapy. The goal of this so-called "staging laparotomy" is to assess mobility and tumor size by means of bimanual palpation, to stage the abdominal cavity and to create total fecal diversion by performing an endcolostomy in order to condition these patients for maximum tolerance during the protracted radiotherapy course (greater than 50 Gy/5-6 weeks). The formation of an endcolostomy seems to avoid severe morbidity and even mortality of high-dose radiotherapy without delay of further surgery. Twenty-two patients with locally advanced rectal carcinoma were treated in this way. The tumor was resectable in 18 of the 20 patients who underwent relaparotomy after high-dose radiotherapy. Six out of the 13 patients with a radical resection died with evidence of disease during the follow-up (2 with local disease). One patient died with no evidence of disease after 5 years and 6 patients are still alive without disease after an average of 37 months (15-67 months).
