Site-dependent resection techniques for gastric cancer.
In addition to tumor stage and growth pattern, the tumor site is a major factor in determining the extent of resection and lymphadenectomy necessary in patients with gastric carcinoma. Total gastrectomy with D2-lymphadenectomy is the procedure of choice for tumors of the gastric corpus. Extended total gastrectomy with trans-hiatal resection of the distal esophagus is required for tumors of the proximal region; in these patients lymphadenectomy may also include splenic hilum and left retroperitoneal nodes. In patients with distal gastric carcinoma, a subtotal gastrectomy often achieves a complete tumor resection. Extended lymphadenectomy in these patients includes the retroduodenal and right para-aortic nodes in addition to a D2-dissection. In patients with early tumor stages, anatomically oriented limited resection techniques are increasingly important. The concept of the sentinel lymph node may result in more selective lymphadenectomy strategies in the near future [15]. For patients with a locally advanced disease, these surgical concepts must be evaluated within multimodal treatment protocols [16].
