title: [Surgical standards in primary colon cancer].
abstract: The surgical standards in the treatment of primary cancer of the colon include the radical resection of the tumor-bearing colon with truncal ligation of its vessels. Eradication of the tumor with complete dissection of the lymphatic drainage area increases the chance for cure (R0). The lymphatic dissection determines the extent of colonic resection: right hemicolectomy (ileo-transversostomy) with truncal ligation of the iliocolic and right colonic arteries for carcinomas of the cecum and ascending colon; transverse colectomy (ascendo-descendostomy) with ligation of the middle colic artery for carcinomas in the middle of the transverse colon; left hemicolectomy (transverso-rectostomy) with ligation of the inferior mesenteric artery at the aorta for cancer of the descending and sigmoid colon; extended sigmoid resection (descendo-rectostomy) with central lymphadenectomy and ligation of the inferior mesenteric artery distal to the left colic artery for cancer of the distal sigmoid colon. Carcinomas located in between two drainage areas (lateral transverse colon, hepatic or splenic flexure) are treated by extended hemicolectomies or subtotal colectomies with dissection of two lymphatic drainage areas. The monobloc no-touch isolation technique requires the ligation of vessels prior to the mobilisation of the colon. Exceptions from these standard operations (limited resections) are necessary for metastatic disease or in the acute emergency situation of perforation or obstruction. Application of these surgical principles will ensure the best possible treatment results in primary colonic cancer.
