RESUMO
Objective To observe the safety and efficacy of RPH with the simplified. Milligan-Mor- gan(M-M) surgery on mixed hemorrhoids. Methods Totally 1 200 patients with mixed hemorrhoid were assigned to the control group(600 cases) and the treatment group(600 cases) according to randomized, parallel controlled,multi-center trial design. Patients in the control group received PPH with the simplified M-M surgery, and patients in the treatment group received RPH with the simplified M-M surgery. Postop- erative complications, operation time,the postoperative hospitalization days and the efficacy were ob- served. Results Compared with the control group, the numbers of postoperation hemorrhage, postop- erative uroschesis, anal fissure and anorectal stenosis in treatment group were decreased(P <0. 01 , P < 0. 05), operation time and the postoperative hospitalization days were decreased (P <0. 01 , P <0. 05 ), the cure rate for 3 and 12 months after operation were increased (P <0. 01, P <0. 05). Conclusions RPH with the simplified M-M surgery could reduce the incidence of postoperative complications,improve the clinical cure rate and the curative effect in treatment of mixed hemorrhoids.
