PPH与肛垫保存术治疗重度痔的临床对比研究

Comparative Study on the Therapeutic Effects of PPH and Anal Cushion Preserved Procedure in the Treatment of Severe Hemorrhoids

通过吻合器痔上黏膜环切钉合、肛垫复位固定术（PPH）与肛垫保存术治疗重度环状痔各35例，术后2个月至2年随访观察，比较两组的临床疗效。PPH组在手术时问、术后疼痛指数、术后出血、注射止痛药次数、术后刨面水肿、住院时间、恢复工作时间方面均优于对照组。术后尿潴留、痔复发方面差别两组无统计学意义。结果显示，PPH治疗重度环状痔具有手术时间短、术后出血少、疼痛轻、创面水肿轻、恢复快、疗效好等优点。

Thirty five patients with severe circumferential hemorrhoids underwent PPH treatment（PPH group） ,while another 35 cases with the same diseases underwent anal cushion preserved procedure（con- trolled group）. Postoperative follow-up of 2 24 monthcs was made, and the theraputic effects were compared. Results showed that PPH group was better in the aspects of operation duration of time,postoperative pain index, postoperative bleeding, time of analgesic injection, postoperative edema of the wound, days of hospitalization and recovery. There was no statistical significance in postoperative urine retention and recurrence of hemorrhoid between the two groups. It is suggested that PPH is of such strong points in the treatment of severe circumferential hemorrhoid as shorter duration of operation, less postoperative bleeding, less pain. less edema of wound, quicker recovery and better therapeutic effect.
