Simultaneous incision and suturing of a large wound in the full-layer resection of stromal tumor under the traction of a snare -- a new method of endoscopic suturing.

A 67-year-old woman with abdominal distension underwent endoscopy and computed tomography examination, in which a stromal tumor, approximately 1.7 × 1.7 cm in size, was identified in the fundus of the stomach. Most of the tumor was in the serosal layer ([Fig. 1]), and therefore traditional endoscopic full-thickness resection could not remove the tumor [1] [2].
