ABSTRACT
Objective:To investigate the feasibility,moderate-and short-term efficacies of laparoscopic surgery in the resection of the gastric gastrointestinal stromal tumors(GIST)with the tumor diameter more than 5 cm.Methods:The clinicopathological data of 26 gastric GIST patients with the diameter more than 5 cm underwent laparoscopic complete resection were retrospectively analyzed.The postoperative recovery,complications and moderate-and short-term prognosis of the patients were observed.Results:All the patients underwent laparoscopic surgery resection without open operation.According to the location and growth types of tumors,the total gastrectomy was performed in 1 case,the approximal gastrectomy was performed in 2 cases,the distal gastrectomy was performed in 2 cases,and the gastric local resection was performed in the rest 20 cases.The mean diameter of tumors was (5.94±1.28) cm,the mean operational time was (84.23±27.02) min,and the mean blood loss was (72.38±34.24) mL.The postoperative recovery time of bowel function was (2.77±0.65)d and the mean length of postoperative hospitalization time was (7.04±2.24) d.There was 1 case of intraperitoneal hemorrhage and 1 case of anastomotic stenosis;they recovered after conservative therapy.The postoperative pathology results(according to the modified NIH standard) indicated the number of moderate-risk patients was 18(69.23%),and the number of high-risk patients was 8(30.77%).A total of 12 cases accepted the adjuvant therapy with imatinib.There was 1 case of hepatic multimetastasis,and there was no local recurrence or death in the other patients.Conclusion:The moderate-and short-term efficacies of laparoscopic surgery in the gastric GIST patients with the tumor diameter more than 5 cm is safe and feasible.
