Abstract: Objective To discuss and study the clinical effect of photodynamic therapy combined with liquid nitrogen cryotherapy on the treatment of condyloma acuminatum. Methods Totally 100 adult patients with condyloma acuminatum were randomly divided into two groups. The control group was treated with photodynamic therapy, and the observation group was treated with photodynamic therapy combined with liquid nitrogen freezing. The total effective rate, recurrence rate, adverse incidence rate, and wart removal before and after treatment were compared. Rate and the distribution of 21 HPV genes. Results The total effective rate of the observation group was 96%, the recurrence rate was 6%, and the incidence of adverse reactions was 10%; the total effective rate of the control group was 90%, the recurrence rate was 26%, and the incidence of adverse reactions was 38%. After treatment, the diameter of warts in the observation group shorter than the control group, the difference between the two groups is statistically significant (P<0.05). Conclusion Compared with the single application of photodynamic therapy, photodynamic combined with liquid nitrogen cryotherapy has a significant effect on the treatment of condyloma acuminatum, with high treatment efficiency, high wart clearance rate, low recurrence rate and adverse reaction rate, and it is worthy of clinical promotion.
