title: Laparoscopic surgery for gastric gastrointestinal stromal tumor is feasible irrespective of tumor size.
abstract: OBJECTIVE
  To compare the outcomes of laparoscopic surgery and open surgery for gastric gastrointestinal stromal tumors (GISTs) by size-matched analysis and evaluate whether laparoscopic surgery for lesions of >5 cm is feasible.
  
  
  METHODS
  Data of 44 consecutive patients with gastric GIST who underwent surgery from 1988 to 2011 were reviewed. Twenty-three patients who underwent successful laparoscopic surgery were compared with 10 patients with similar tumor sizes who underwent open surgery. Among the 23 patients in the laparoscopic group, we compared postoperative results between GISTs of ≤5 cm and >5 cm.
  
  
  RESULTS
  There were no differences in clinicopathological characteristics between the laparoscopic surgery group (LG) and the open surgery group (OG). The operation time was not different, but the blood loss (5.5 mL [range, 0-425 mL] in LG and 125 mL [range, 0-676 mL] in OG) (P=.008) and postoperative hospital stay (21 days in OG and 8 days in LG) (P<.001) were significantly less in the LG. Postoperative complications and recurrence were not different. Comparison between patients with lesions of >5 cm and patients with smaller lesions in the LG found that smaller lesions were associated with a shorter postoperative hospital stay (7.5 days versus 11 days) (P=.037).
  
  
  CONCLUSIONS
  Laparoscopic resection of primary gastric GISTs is feasible even for tumors of >5 cm.
