Comparison of the Clinical Efficacy and Safety of Endoscopic Superior Rectal Mucosal Ligation and Hemorrhoids Ligation

The patient takes the left side decubitus position, the endoscope is connected with 6 serial ligators, the cup of the sleeve is pointed at the upper edge of the straight anal line and the rectal mucosa is continuously aspirated under negative pressure. The mucosa enters the sleeve and sees a full-screen red sign. The sensing loop is successfully triggered, indicating that the loop is complete.

The patient takes the left side decubitus position,the endoscope is connected with 6 serial ligators,the cup the sleeve is aligned with the base of the hemorrhoid (above the dentate line) for continuous negative pressure suction.The hemorrhoid enters the sleeve and sees a full-screen red sign. Turn the handle of the sleeve clockwise and feel that the loop is successfully triggered, the ligature is completed.
