This document discusses surgical techniques for treating gastroesophageal cancers and early stage esophageal adenocarcinoma. It finds that laparoscopic staging is useful for gastric cancer and laparoscopic resection may provide benefits over open surgery. While D2 lymphadenectomy provides more thorough staging, it also carries higher risks than D1 with no clear survival benefit. For early esophageal cancers, esophagectomy carries a small but definite risk of recurrence compared to endoscopic mucosal resection, but laparoscopic esophagectomy outcomes are similar to open surgery.

- Figure 11-22. Level of lymph node dissection. Data from several series suggest that the level of lymph node dissection accompanying gastrectomy for gastric cancer can influence survival. The lymphadenectomies that have come into use are classified according to the specific echelon of nodes removed and may differ depending on tumor location. A , Tiers of nodes from perigastric (N1) to para-aortic (N4) are shown. B , Removal of the primary draining lymph nodes (N1) shown as closed circles in with greater and lesser omenta is an R1 dissection and constitutes the minimal acceptable operation for gastric cancer. R2 dissection requires secondary lymph node excision (N2) in the celiac and hepatic regions, as well as splenic hilar nodes when the tumor involves the adjacent stomach. Splenectomy is controversial as a means to remove the latter nodes. More extensive dissections (R3) of tertiary nodes and the lining of the lesser sac are rarely performed because of their greater morbidity and unclear benefits.

- Figure 11-19. Operations for gastric carcinoma. At the present time, surgical extirpation is the only method of cure for invasive gastric cancer. In the United States, however, 10% to 15% of patients with gastric carcinoma will prove to be resectable for possible cure (removal of all gross disease with microscopic margins free of tumor) at operation. Of these, only a subgroup of patients with early disease by careful staging have a good chance of 5-year survival. Although the operations offered to patients for gastric cancer vary in their technical aspects related to lymph node dissection, distal subtotal gastrectomy ( A ) and total gastrectomy ( B ) remain the operations of choice in treating resectable gastric cancers with the exception of those involving the gastric cardia. This latter group is managed by esophagogastrectomy. The distal stomach can be brought up to either the midesophagus in the right chest or to the cervical esophagus after transhiatal esophagectomy []. ( From Scott et al. []; with permission.)
- Figure 12-29. A-B , Lymph node involvement. Identification of lymph node involvement is best characterized by mapping of the cervical, mediastinal, and subdiaphragmatic areas. This information is useful in predicting survival rates as well as in directing radiation therapy. ( Adapted from Casson [].)
