Comparison of laparoscopy combined with gastroscopy positioning and open resection for gastric stromal tumours: A meta-analysis

BACKGROUND AND OBJECTIVES: The aim of the study was to assess the efficacy and safety in treating gastric stromal tumours by laparoscopy combined with gastroscopy positioning surgery. METHODS: I searched the randomized controlled trials (RCTs) about the efficacy and safety of laparoscopy combined with gastroscopy positioning surgery in treating gastric stromal tumours from the PubMed (1998～2018.06), Wanfang Data (1990～2018.06), China National Knowledge Infrastructure (1979～2018.06) and International Statistical Institute (1998～2018.06). I extracted the data from these trials, and I got the meta-analysis from RevMan 5.3 software. RESULTS: Twenty-six RCTs involving 1710 patients were included (870 patients in the laparoscopy combined with gastroscopy positioning group and 840 patients in openresection group). Compared with open resection group, this meta-analysis showed that laparoscopy combined with gastroscopy positioning group could reduce the intraoperative blood (P < 0.05), shorten the post-operative time of recovery of intestinal peristalsis (P < 0.05), shorten the diet recovery time (P < 0.05), reduce the incidence of the incision infection, intestinal obstruction and pneumonia and also shorten the post-operation hospital stay (P < 0.05). However, there was no significant difference in the operation time (P > 0.05). CONCLUSION: Compared with open resection group, the total effect of laparoscopy combined with gastroscopy positioning group in the treatment of gastric stromal tumours is better. Laparoscopy combined with gastroscopy positioning group for the gastric stromal tumours is acceptable.
