Abstract: Objective To investigate the therapeutic effect of pathological anal fissure tissue resection on chronic anal fissure. Methods The clinical and follow-up data of 46 patients with chronic anal fissure who underwent pathological anal fissure tissue resection in our hospital from September 2019 to April 2020 were retrospectively analyzed. The operation time, intraoperative blood loss, postoperative complications, postoperative pain score, changes of anal canal resting pressure before and after surgery and clinical efficacy were observed. Results The operation time was （35.91±12.35） min, and the intraoperative blood loss was （7.33±3.48） ml. Postoperative urinary retention occurred in four cases （8.70%）, incision infection in one case （2.17%）, no incision bleeding, anal incontinence and other complications. Postoperative pain score： 24 h after operation （3.43±0.91）, 48 h after operation （3.00±0.73）, 72 h after operation （2.22±0.76）, one week after operation （0.67±0.63）. The resting pressure of anal canal was （19.86±2.24） kPa before operation and （10.396±1.97） kPa one week after operation, and the difference was statistically significant （P=0.000）. The wound healing time was （24.26±5.14） days. In this group, 42 cases （91.30%） were cured, 4 cases （8.70%） were improved, and the effective rate was 100%. The median follow-up time was 8 months, and no recurrence was found. Conclusion Pathological anal fissure tissue resection for chronic anal fissure is safe and effective.
