title: Laparoscopic versus open resection of gastric gastrointestinal stromal tumors.
abstract: The aims of this study were to explore whether laparoscopic surgical resections of gastric gastrointestinal stromal tumors (GISTs) would produce better perioperative and similar oncologic outcomes compared with open surgical resection in Chinese patients. Thirty-six gastric GISTs cases were divided into a minimally invasive laparoscopic group and open resection group, depending on the surgical approach that was used. The general preoperative information, operative time, incision length, intraoperative blood loss, postoperative time to first flatulence, postoperative complications, postoperative hospital stay, total hospitalization costs, and such follow-up data as recurrence, metastasis, and mortality rates were compared between two groups. Among the 36 gastric GISTs, 15 received laparoscopic surgical treatment (laparoscopy group, n=15), and 21 received routine open resection treatment (open resection group, n=21). The laparoscopy group and the open resection group showed statistically significant differences (P<0.05) in incision length (7.8±2.3 vs. 16.9±3.8 cm), postoperative time to first flatulence (3.8±1.3 vs. 5.1±2.1 d), postoperative hospitalization time (7.6±2.5 vs. 11.3±3.7 d), and total cost of hospitalization (RMB 28,239±5,521 vs. RMB 23,761±5,362). There were no statistically significant differences (P>0.05) between the laparoscopy group and the open resection group in operative time (147.8±59.3 vs. 139.2±62.1 min) and intraoperative blood loss (149.8±98.9 vs. 154.2±99.3 mL). Both groups had no postoperative complications, no recurrence and metastasis, and no postoperative mortality. There were no statistically significant differences between the two groups in postoperative complications, postoperative recurrence and metastasis, and postoperative mortality. In conclusion, compared with open resection, the laparoscopic resection of gastric GISTs offers the advantages of less trauma, faster recovery, and shorter hospital stay.
