 Necessity for more accurate preoperative staging to determine the proper treatment strategy for locally advanced gastric cancer Intraabdominal observation with laparoscopy is useful to determine the appropriate staging for patients with type 4 gastric cancer or highly advanced one. The aim of this study is to clarify the role of staging laparoscopy in patients with locally advanced gastric cancer. Twenty-one patients with T 3 or T 4 gastric cancer underwent staging laparoscopy(SL)with peritoneal lavage cytology. The stages determined by SL were compared with those obtained by conventional methods like preoperative CT scan. The discrepancy rate of staging was 38%(8/21), with down-staging in 3 of 11(28.5%)patients with SL and up-staging in 5 of 10(50%)patients with SL. SL is an effective tool for detecting unsuspected peritoneal metastasis . Moreover SL plays an important role for determining the appropriate stage for local advanced gastric cancer.
