Abstract:

Objective To explore the safety and feasibility of laparoscopic combined with endoscopic sinus surgery for gastric stromal tumors (GST). Method The clinical data of 8 cases of GST hospitalized patients undergoing laparoscopic extracranial tumor wedge resection after application of the electronic gastroscope positioning were retrospectively analyzed from August 2018 to November 2019 in the Donggang Branch of the First Hospital of Lanzhou University. Result 8 patients with GST were treated with laparoscopic tumor outside the gastric cavity wedge resection after electronic gastroscope positioning and the operation was successfully completed without metastatic laparotomy and intraoperative death. The operation time(71.6±9.8)min, intraoperative blood loss (35.0 ± 10.8) ml, postoperative gastrointestinal function recovery time (2.8±0.7) d, postoperative bedtime (1.0±0.4) d, Time for feeding semi liquid food (2.7±0.5) d, and postoperative hospital stay (6.8±1.7) d. 8 patients had no anastomotic bleeding, anastomotic fistula, anastomotic stenosis, incision infection, intestinal obstruction, urinary tract infection and pulmonary infection and other complications, and pathological biopsy confirmed GST, margin were not seen tumor organization. 8 patients were followed up for 6 months. All follow-up cases were examined by computed tomography and electron microscopy, no recurrence and metastasis were observed. Conclusion Laparoscopic combined with endoscopic sinus surgery for the treatment of GST is a safe and feasible precision minimally invasive surgical method, with accurate positioning, short operation time, less intraoperative bleeding and low complications.
