Conclusions  Although this study was a limited, prospective, animal survival study without a control arm, it again indicates that STAT allows safe abdominal access, a reliable means of closure, and directed endoscope positioning. Although one significant mucosal tear did occur, this study suggests STAT will tolerate the mechanical forces of peroral transgastric procedures provided the organ resected is small to moderate in size (<8 Ãƒâ€” 3 cm).
