Comparative study of external dissection & internal ligation versus Milligan-Morgan haemorrhoidectomy for mixed hemorrhoids / 中国医师进修杂志

ABSTRACT

Objective To study the efficacy of external dissection & internal ligation for beating mixed hemorrhoids, and compare with Milligan-Morgan. Methods One hundred and twenty-six patients with mixed hemorrhoids were divided into two groups treatment group(66 cases)and controlled group(60cases).In treatment group used external dissection & internal ligation for treating mixed hemorrhoids, but in eontrolled group used Milligan-Morgan. Then the differences between both groups in healing time of wound surface, as well in the statuses of bleeding, pain, edema, anus stenosis, and anus overflow liquid were observed. Results Averaged healing time in treatment group was significantly shorter than that in controlled group, (8.2±2.6)days vs (17.4±3.8)days, P＜0.01.The anus stenosis and anus overflow liquid were significantly less in treatment group than those in controlled group, P＜0.01.Conclusion External dissection & internal ligation of hemorrhoids for treating mixed hemorrhoids decreases anal transitional zone(ATZ)disorganization, shorten healing time, and significantly decreases crissum scar,protectes anus function effectively.
