Background:
Laparoscopy-assisted surgery has proved useful in the treatment of early gastric cancer, but its use in advanced cancer may be hindered by limitations in lymphadenectomy.
Study Design:
Data on lymph node retrieval after distal gastrectomy with D1 or D2 lymphadenectomy (n = 89) performed by the laparoscopy-assisted approach were collected between 1998 and 2002 and compared with data obtained from conventional open surgery performed for T1 cancer at a high-volume hospital (n = 342) during the same period. Comparisons of total number of lymph nodes, retrieval at each lymph node station, and the rate of noncompliance (no nodal tissue documented at a node station that should have been resected) were conducted using Student's t-test and the chi-square test.
Results:
D2 resection by the laparoscopy-assisted approach harvested a sufficient number of nodes for adequate TNM classification (>15 nodes) in 86% of patients. Nevertheless, a significantly greater number of lymph nodes were harvested by open surgery. The difference was significant for the perigastric lymph nodes along the major curvature (Nos. 4 and 6) and second tier nodes along the celiac and splenic arteries (Nos. 9 and 11).
Conclusions:
The extent of lymphadenectomy achieved by current laparoscopic procedure approaches the global standard for accurate staging, although performing extended resection as recommended in Japan remains a challenge.
