To compare the clinical effect of using RPH-4 to form zigzag line for binding point connection Combined with external hemorrhoidectomy and suture and PPH in the treatment of mixed hemorrhoids with grade Ⅱ~Ⅳ.

From April 2018 to April 2020, 120 patients with mixed hemorrhoids of grade Ⅱ~Ⅳ were included in Anorectal Department of Suzhou Integrated Traditional Chinese and Western Medicine Hospital as the study object, and randomly divided into treatment group and control group, sixty cases in each group. Serrated ligation with RPH-4 was performed in the treatment group and PPH in the control group.

The treatment group of the operation time (t=-9.351, P<0.05), intraoperative bleeding volume (t=-18.571, P<0.05), hospitalization time (t=-4.471, P<0.05), postoperative complications were significantly better than control group [pain (The first day after operation: t=-15.879, P<0.05; the third day after operation: t=-3.901, P<0.05), hemorrhage (The first day after operation: t=-6.914, P<0.05; the third day after operation: t=-2.335, P<0.05), edema (The first day after operation: t=-4.068, P<0.05; the third day after operation: t=-4.424, P<0.05)]. Total effective rate of the treatment group (98.3%) were significantly better than those of the control group (93.3%) (χ²=8.26, P<0.05).

Automatic ligation is superior to hemorrhoid mucosal circumcision in the treatment of grade Ⅱ~Ⅳmixed hemorrhoids. It is safe, rapid and effective in relieving clinical symptoms, and is more conducive to postoperative rehabilitation. It is worthy of clinical promotion.
