Published studies on endoscopic full-thickness resection with pure NOTES in humans

NOTES = natural orifice transluminal endoscopic surgery; GIST = gastrointestinal stromal tumor; OTSC = over-the-scope clip. ^*Success of complete and en bloc resection followed by clipping using pure NOTES. ^†In 6 of 20 cases, pure NOTES was impossible and conversion to laparoscopic wedge resection was necessary due to extraluminal growth and the large size of the tumors. Incomplete resection with positive deep margins occurred in 2 cases of 14 patients in the pure NOTES group. ^‡Needed ulltrosound-guided percutaneous puncture drainage.
