Objective: To investigate the safety and oncological prognosis of laparoscopic seromuscular dissection (LSD) in the treatment of gastric stromal tumors.
Material and methods: From June 2016 to July 2022, 67 patients with gastric stromal tumors underwent laparoscopic seromuscular dissection (LSD), and 58 patients underwent non-LSD surgery during the same period (52 patients underwent laparoscopic gastric wedge resection (LWR), two patients underwent proximal gastrectomy, three patients underwent total gastrectomy, one patient underwent distal gastrectomy and partial hepatectomy). Gastric stromal tumor patients were compared to compare the surgical results, tumor relapse rate, and survival rate of the two groups.
Results: The results of the two groups were compared. For gastric stromal tumors, especially gastric stromal tumors located at 'difficult sites', LSD can reduce the amount of bleeding and the number of cutting staplers used during the operation, reduce the incidence of postoperative complications, shorten the postoperative hospitalization time, reduce the hospitalization cost and improve the quality of life of patients without increasing the operation time.
Conclusion: Laparoscopic seromuscular dissection for gastric stromal tumors is safe and technically feasible in the hands of experienced laparoscopic surgeons.
