3. Familial Polyposis of the Colon

Abstract

Analysis was made on the 7 cases of familial polyposis of the colon in our clinic and those collected from the Japanese literature.In our cases, malignant changes were found in 4 cases operatively. One case of them was performed panproctocolectomy with permanent ileostomy. As liver metastasis and peritonitis carcinomatosa wererecognized in 3 cases of them, palliative operation such as partial resection of the colon, anastomosis of the colon or amputatio recti were carried out.Three other cases had no malignant changes. Because of bleeding tendency with thrombocytopenia was found in one case of them, total colectomy with excluding of the rectum was performed. One case of 18-year-old male was carried out the total colectomy, resection of the rectal mucosa and anal ileostomy. Sphincter muscle of the anus could preserve on this case, more physiological fecal continence was obtained by this operative procedure than permanent ileostomy. The last case without malignancy had small number of the polyps in rectal region, and total colectomy with ileoproctostomy was performed. Several times of fulguration of polyps in the remaining rectum was carried out after operation. In. spite of the frequent incidence of carcinoma in the preserved rectum after ileoproctostomy, . good results of anal function and normal continence could be obtained by this operative: method.
