ABSTRACT
The incidence of severe mixed hemorrhoids is increasing year by year, and its surgical method has always been the focus in the study of anoenterology. On the basis of anal cushion downward movement theory, anal cushion suspension surgery moves up prolapsed anal cushion by suturing or ligating the mucosa above the dentate line. This not only ensures the effect of surgical treatment, but also protects the structure and function of the canal and anus in the most fine, which is in line with the minimally invasive treatment idea of severe mixed hemorrhoids, and is gradually widely used in clinical practice. As a new surgical method, anal cushion suspension surgery has unique advantages in treating severe mixed hemorrhoids, especially in severe prolapsed hemorrhoids. This paper will analyse the key points of anal cushion suspension surgery combined with procedure for prolapse and hemorrhoids, milligan morgan, hemorrhoidal artery ligation, automatic ligation of hemorrhoids, injection sclerotherapy, laser ablation and mixed surgeries respectively, in order to provide reference for clinicians to operate on severe mixed hemorrhoids.
ABSTRACT
Traditional Chinese surgical treatment "suture-dragging" therapy is based on medical thread therapy and tight seton drainage in combination of minimal invasive surgical principle. It can preserve the integrity of anal sphincter musculature involved in fistulous tract or abscess and maintain anal function. This article not only describes in detail about the operation points and mechanisms of "suture-dragging" therapy of anorectal fistula, but also reviews the application and modification of anorectal disease.

Objective: To observe the effects of mild moxibustion on angiogenesis and microcirculation in wound repair after operation of anal fistula, and to explore the mechanism of action. Methods: Seventy-two SD male rats were made to bear an "acute, open, bleeding, infected" wound surface and were divided randomly into mild moxibustion group, microwave group and control group (24 rats per group). The wound surfaces of the treatment groups were treated for 15 min with mild moxibustion or microwave medical instrument from the first day after operation, and the control group was not given any treatment. At the first, third, seventh and fourteenth days after operation (1, 3, 7 and 14 days of treatment), six rats in each group were sacrificed after examining the blood flow of the wound surface, and the samples of granulation tissues were collected. The numbers of CD34 and positive expression of vascular endothelial growth factor (VEGF) in granulation tissues were detected. Results: In the early and middle stages of wound healing, mild moxibustion could obviously increase the expression of VEGF, the number of CD34, and the blood flow of the wound surface. And the expression of VEGF, the number of CD34, and the blood flow of the wound surface began to increase at the third day, and reached the peak level at the seventh day, and then began to decrease. In the late stage of wound healing (day 14), mild moxibustion could decrease the expression of VEGF, the number of CD34, and decrease the blood flow of the wound surface. There were significant differences between the mild moxibustion group and the control group in the blood flow of the wound surface, the expression of VEGF and the numbers of CD34 in granulation tissues (P<0.05) after treatment, and except the number of CD34 at 14-day treatment, there were also differences between the mild moxibustion group and the microwave group. Conclusion: Mild moxibustion has better regulative actions on blood flow of the wound surface and the number of CD34 and positive expression of VEGF in granulation tissues, and can regulate microcirculation in wound surface and promote the wound healing.
ABSTRACT
OBJECTIVE: To evaluate the efficacy and safety of thread-dragging through fistula method in treating patients with simple anorectal fistula. METHODS: In this multi-centered, prospective, and randomized controlled clinical trial, 244 patients with simple low or high anorectal fistula were randomly divided into study group (with the method of thread-dragging through fistula) and control group (with the method of incision or thread-drawing). The healing time and curative rate of anorectal fistula, and the integral calculus of clinical symptom and life quality evaluations before and after treatment were all examined. The maximal anal canal squeeze pressure was measured to compare the therapeutic safety between these two groups. The health economical benefits were also assessed to determine which therapeutic method was more economical. RESULTS: The curative rate of simple low and high anorectal fistula were of no significant differences between the study group and the control group. The healing time of simple low anorectal fistula in the study group and the control group were (22.26+/-8.67) d and (31.41+/-11.39) d respectively, while the healing time of simple high anorectal fistula in the study group and the control group were (24.73+/-8.15) d and (32.20+/-12.60) d respectively, and there revealed significant differences between these two groups. Each integral calculus of clinical symptom evaluation in the study group was not obviously different from those in the control group besides the integral calculus of anal sphincter function. The integral calculus of life quality between the study group and the control group of simple low anorectal fistula had no significant differences. The integral calculus of anal sphincter function and confidence in treatment in the study group of high anorectal fistula were better than those in the control group. The hospitalization expense of the study group was remarkably lower than that of the control group. The maximal anal canal squeeze pressure in the study group after treatment was not reduced obviously as compared with that in the same group before treatment, while it was decreased significantly in the control group after treatment as compared with those in the same group before treatment and in the study group after treatment. CONCLUSION: The method of thread-dragging through fistula in treating simple low and high anorectal fistula can shorten the course of the disease, save the hospitalization expenses, improve the life quality of the patients, and protect the anal sphincter function.
