title: Laparoscopy in the management of gastric adenocarcinoma.
abstract: OBJECTIVE
  The authors determined the accuracy of laparoscopy in detecting metastatic disease in patients with gastric adenocarcinoma.
  
  
  BACKGROUND
  The majority of patients with gastric adenocarcinoma in the United States present with advanced disease. They are at high risk for intraabdominal metastatic spread.
  
  
  METHODS
  One hundred eleven patients with gastric adenocarcinoma underwent laparoscopy at Memorial-Sloan Kettering Cancer Center from December 1991 to December 1995. All were judged to be free of intra-abdominal metastatic disease on preoperative computed tomographic scan imaging.
  
  
  RESULTS
  Laparoscopic exploration was successful in 110 of 111 patients and accurately staged 94% of the patients with respect to metastatic disease with a sensitivity of 84% and a specificity of 100%. The prevalence rate of metastatic disease was 37%. Twenty-four patients underwent laparoscopy only and were discharged in an average 1.4 days versus 6.5 days in patients undergoing exploratory laparotomy without resection (p < 0.05). No patients undergoing laparoscopy only have returned for palliative surgery.
  
  
  CONCLUSIONS
  Laparoscopy should be performed in nonobstructed, nonbleeding patients with advanced gastric cancer in the United States. More than one third of these patients have unsuspected metastatic disease at time of operation. Laparoscopy is highly accurate in detecting occult metastases and identifies a unique population of stage IV patients who may benefit from newer induction chemotherapeutic approaches while avoiding unnecessary laparotomy.
