外剥内扎加肛周皮瓣整形术治疗混合痔100例临床观察

External Dissection and Internal Ligation with Perianal Flap-plasty for Mixed Hemorrhoids： Clinical Observation of 100 Cases

为观察外剥内扎加肛周皮瓣整形术治疗混合痔的疗效，将200例混合痔患者随机分为两组，治疗组100例采用外剥内扎加肛周皮瓣整形术治疗．对照组100例采用单纯外剥内扎术治疗，比较两组的疗程、创面愈合时间等指标。结果显示，治疗组疗程短于对照组[（16．0±5．2）dVS（21．2±6．1）d，P〈0．013，治疗组在创面愈合时间、术后疼痛积分、尿潴留和感染发生率方面均优于对照组（P均〈0．05）。结果表明，外剥内扎加肛周皮瓣整形术治疗混合痔疗效优于单纯外剥内扎术。

This study was to observe the clinical efficacy of external dissection and internal ligation with perianal flap-plasty in treating mixed hemorrhoids. The 200 cases with mixed hemorrhoids were randomly divided into two groups： treatment group and control group, 100 cases for each. External dissection and internal ligation with perianal flap-plasty was performed oi1 treatment group, while external dissection and internal ligation alone on control group. Indicators such as treatment course, wound surface healing time etc. were compared between both groups. The results showed that treatment group had shorter treatment course than the control group[（16.0±5.2）d vs （21.2±6.1）d, P〈0.01]; treatment group was superior to the control group in wound surface healing time, scores of postoperative pain, urinary retention and in- cidence of infection （all P 〈0.01）. It is concluded that external dissection and internal ligation with peri anal flap-plasty is better than alone external dissection and internal ligation in treating mixed hemorroids.
