Abstract:

Objective

To compare the difference in long-term efficacy between injection therapy and other non-injection therapy for the treatment of complete rectal prolapse.

Methods

A retrospective cohort study was conducted to include 180 patients with complete rectal prolapse who were treated with Xiaozhiling injection therapy (116 patients) versus non-injection therapy (64 patients) at Guang'anmen Hospital of the China Academy of Traditional Chinese Medicine from January 1, 2013 to June 30, 2024. Statistical analyese were performed using the R and Fengrui statistical software, with two consecutive survival analysis models constructed to compare patients with different treatment modalities for overall recurrence rate, cumulative recurrence-free survival rate, and postoperative distant recurrence.

Results

The recurrence rate was lower for non-injection therapy (28.1%) than for injection therapy (42.2%). In the unadjusted model, hazard ratio (HR) was 1.34 for non-injection therapy, while it was 1.34 after adjusting for age and sex (model 1), and 1.35 after further adjusting for disease duration and prolapse length (model 2) (0.62~2.96, P=0.451). All models showed that the risk of recurrence associated with injection therapy was not significantly different from that with non-injection therapy, and the cumulative recurrence-free survival analysis was consistent with the results of the multi-factorial analysis.

Conclusion

Despite numerically lower recurrence rates with non-injection therapy, the effect of treatment modality (injection therapy vs. non-injection therapy) on the risk of recurrence was not statistically significant after adjusting for age, sex, duration of disease, and length of prolapse, suggesting that the choice of treatment modality is not a central factor in independently predicting recurrence.
