Abstract:Objective To investigation the effect of endoscopic surgery in patients with gastric gastrointestinal stromal tumor (gastric GIST) of 2~5 cm.Methods 412 patients with gastric GIST who were treated from January 2017 to January 2020 were selected and divided into the endoscopic resection group (endoscopy group, 196 cases) and the laparoscopic resection group (laparoscopy group, 216 cases) according to different surgical methods. The perioperative indexes, postoperative complications, tumor localization, risk classification and postoperative follow-up status of two groups were observed.Results The comparison of the basic data showed that there were no significant differences between the two groups in terms of gender ratio, age, tumor localization, risk classification, previous operations in the history and tumor origin (P > 0.05). The operation time, fasting time, gastric tube indwelling time, postoperative hospitalization time and postoperative defecation time in the endoscopy group were shorter than those in the laparoscopy group, intraoperative blood loss in the endoscopy group was less than that in the laparoscopy group, the incidence of postoperative complications was 18.37% in the endoscopy group, which was lower than 27.78% in the laparoscopy group, the difference were statistically significant (P < 0.05). The followed up was 13~33 months in the endoscopy group postoperatively, with an average of (23.04 ± 10.38) months. The followed up was 13~35 months in the laparoscopy group postoperatively, with an average of (22.71 ± 10.69) months. There were 4 cases of postoperative recurrence in the endoscopy group, with no metastasis, accounting for 2.04%, there were 8 cases of recurrence and 8 cases of metastasis in the laparoscopy group, accounting for 7.41%. There were 4 cases of damaged tumor bodies in the endoscopy group, accounting for 2.04%, there were 8 cases of damaged tumor bodies in the laparoscopy group, accounting for 3.70%. There were no deaths in either group, and the difference in the above indicators was not significant (P > 0.05).Conclusion Endoscopic surgical treatment for gastric GIST patients with 2~5 cm can reduce intraoperative bleeding, improve postoperative recovery and reduce the occurrence of postoperative complications with good safety, which can be clinically promoted.
