title: Laparoscopic resection of gastrointestinal mesenchymal tumors located in the upper stomach.
abstract: BACKGROUND
  The treatment strategy for a gastrointestinal mesenchymal tumor located close to the esophagogastric junction remains controversial. The authors evaluate the criteria indicating that a gastrointestinal mesenchymal tumor is suitable for laparoscopic resection and assess the surgical techniques on the basis of clinical outcomes.
  
  
  METHODS
  The criteria specified a tumor more than 2 cm in diameter or a tendency for it to increase in size during the follow-up period. For eight patients in whom the tumor was located within 3 cm of the esophagogastric junction, an intragastric laparoscopic approach was used, whereas for seven patients in whom the tumor was further from the esophagogastric junction, an exogastric approach was used.
  
  
  RESULTS
  In all 15 cases, the laparoscopic resection was successful, with no complications. The intragastric group had a mean maximal tumor size of 2.9 cm, a mean operation time of 168 min, and a mean postoperative hospital stay of 8.8 days, whereas these values in the exogastric group, were respectively, 3.9 cm, 121 min (p = 0.0442), and 9.6 days. There were no recurrences in either group during the follow-up period.
  
  
  CONCLUSIONS
  The good clinical outcomes suggest hat the criteria used as an indication for laparoscopic resection and the surgical techniques applied were appropriate for the resection of gastrointestinal mesenchymal tumors.
