Abstract
Objective To study the clinical efficacy of low-cut high-level virtual hanging in the treatment of high anal fistula. Methods Ninety-four cases with high anal fistula were divided into treatment group and control group according to random number table method. Patients in the treatment group were treated with low-cut high-level virtual hanging therapy, while patients in the control group were treated with common low-cut high-level hanging therapy. During the 3 months following-up, the anus and rectal pressure including rectal rest pressure (RRP), anal rest pressure (ARP), anal longest construction time (ALCT) and anal maximal construction pressure (AMCP) at the time of discharging, 1 month and 3 months after treatment were recorded. The cure time, cure rate and recurrence rate of the patients were also recorded. Results At the time of discharging, there was no significant difference in the levels of RRP, ARP, ALCT and AMCP among the two groups (P>0.05). The levels of ARP and AMCP in the treatment group were significantly higher than those in the control group (P<0.05). One month after treatment, the levels of RRP, ARP, ALCT and AMCP were [(3.26±0.58) kPa], [(17.63±4.127) kPa], [(37.02±5.35) min], [(23.86±4.89) kPa] in the treatment group, and [(3.07±0.52) kPa], [(16.93±4.11) kPa], [(36.47±5.01) kPa], [(21.92±4.72) kPa] in the control group, respectively. There was no significant difference in RRP and ALCT between the two groups (P>0.05) and the levels of ARP and AMCP in the treatment group were significantly higher than those in the control group (P<0.05). Three months after the treatment, the levels of RRP, ARP, ALCT and AMCP were [(3.53±0.72) kPa], [(19.87±3.82) kPa], [(35.16±5.12) min], [(25.36±5.93) kPa] in the treatment group, and [(3.23±0.68) kPa], [(17.24±3.61) kPa], [(36.25±4.83) min], [(22.65±5.12) kPa] in the control group, respectively. The levels of RRP, ARP and AMCP in the treatment group were significantly higher than those in the control group (P<0.05) and ALCT was significantly lower than that in the control group (P<0.05). There was no significant difference in the total effective rate between the two groups (91.49% vs 89.36%, χ2=0.382, P=0.537), and the average cure time of the treatment group was shorter than that of the control group [(28.43±2.78) d vs (33.62±3.27) d, P=0.03]. There was one case of recurrence in control group. Conclusion Low-cut high-level virtual hanging therapy can significantly protect the anus function of patients with high anal fistula.关键词
