[From endoscopic mucosa ressection to gastrectomy. How radical must surgery be for stomach cancer?].
The aim of surgical treatment is complete resection (Ro-resection) of the tumor in all dimensions of its growth, i.e. resection of the tumor infiltrated stomach including the locoregional lymph nodes. This can be achieved by stage- or histology adapted surgery resulting in subtotal distal and total gastrectomy as complementary procedures. Local excision of gastric carcinoma in curative intent is indicated only in mucosal carcinoma of the intestinal type. The extent of lymph node dissection is still under discussion; the results depend on the experiences of the surgeon. Several studies have shown a prognostic improvement after systematic (D2) lymphadenectomy in stage II/IIIA-disease or in patients with a low incidence of lymph node metastases. Pancreas preserving splenectomy is suggested in tumors of the proximal stomach or after direct infiltration of these organs. The Roux-en-Y procedure represents the most commonly used method of reconstruction after subtotal distal or total gastrectomy. The importance of the duodenal passage as well as of the pouch construction must be investigated in prospective studies in the future. This is true for the value of perioperative multimodal treatment options.
