Objective To investigate the clinical efficacy of pouched suture plus external dissection and internal ligation in the treatment of mixed hemorrhoids. Methods Seventy patients with Ⅲ-Ⅳ internal henmorrhoids and mixed hemorrhoids who were admitted into Jiangsu Provincial Hospital of Traditional Chinese Medicine form June 2015 to June 2016 were enrolled. The patients were randomly divided into two groups: the combined operativ group and control group. The combined operativ group in which 35 cases were treated by pouched suture plus external dissection and internal ligation, and the control group in which 35 cases were treated by external dissection and internal ligation. The wound healing time, clinical curative effect, hospital stay, the operative time and postoperative complications (postoperative pain, edema, postoperative bleeding volume, urination difficulties, residual skin tag, anorectal stenosis) between two groups were compared. Results No significant difference were found in the clinical curative effect, the operative time and anorectal stenosis in two groups (P>0.05). The visual analogue scale (VAS) scores and the edema scores of the combined operativ group on the first day, the third day, and the fifth day after operation were lower than those of control group, the difference was statistically significant (P<0.05), while there were no statistically significant on the seventh day after operation in two groups (P>0.05) . The wound healing time, hospital stay, postoperative bleeding volume, urination difficulties, and residual skin tag in the combined operativ group were significantly shorter or lower than those in the control group (P<0.05). Conclusion Pouched suture plus external dissection and internal ligation has the advantages of less pain, fewer complications and quicker recovery, it also meets the modern concept of minimally invasive, so it is worthy of popularization and application.
