Abstract :During the past 2015-2017 years, patients with gastric submucosal tumor were hospitalized in the
Affiliated Hospital of Hangzhou Normal University.
Method: The treatment of submucous tumor by conventional ESD and Complete removal of
mucous and submucous tissue of the lesion and mucous and submucous tissue of cross-incision
method.
Results: In 40 patients, 37 cases of complete endoscopic gastric submucosal tumor resection, tumor
diameter 1.0 cm - 5.0 cm, complete resection of the tumor with success rate of 92.5%; intraoperative
transit surgery in 3 cases, 1 cases of extracellular growth of tumor and diameter 3.0 cm × 4.0 cm.
1 cases of lesions of capsule with bean curd residue, and cannot be completely stripped, bleeding
in 1 cases and no effective hemostasis; in 37 cases, endoscopic resection of tumor tissue of gastric
mucosa under send pathology, including 30 patients with gastric stromal tumors, 5 cases of gastric
ectopic pancreas, 2 cases of angiomyolipoma.
Conclusion: Conventional ESD technology for large gastric submucosal tumor complete resection
of gastric mucosa and submucosa, such as perforation wound closure is often difficult; "dispel top"
method, the utility model has the advantages of gastric submucosal tumors, first complete resection
of gastric mucosa and submucosa tissue to fully exposed tumor, direct discovery of tumor, increase
tumor stripping efficiency; the "cross incision" method, the utility model has the advantages of
the first lesions of the mucosa and submucosa of cross incision, and complete reservative gastric
mucosa and submucosa, reduce trauma and for large submucosal lesions, for titanium clips closed
the wound and reduce bleeding, perforation and postoperative complications.
