BACKGROUND
Following injection sclerotherapy using ALTA (aluminum potassium sulfate and tannic acid) (ALTAS) and transanal rectocele repair (TAR), changes in anorectal physiology were analyzed to compare the significance of the two treatments.
METHODS
ALTAS was administered to 23 patients and 18 patients were treated using TAR. Efficacy measures included changes in defecography, anorectal manometry and constipation scoring system value.
RESULTS
This was a retrospective cohort analysis conducted on prospectively collected data. Comparing anorectal physiology pre- and post- ALTAS, a statistically significant difference in push was observed with pre-ALTAS treatment (pre-A) at 104.33 ± 4.91° compared with post-ALTAS treatment (post-A) at 113.95 ± 4.74° (p < 0.001). With a pre-A value of 1.55 ± 0.18 cm and a post-A value of 2.46 ± 0.34 cm, perineal descent also showed an increase as well (p < 0.001). The rectocele size decreased post-A from a pre-A value of 7.74 ± 0.86 cm compared with a post-A value of 2.91 ± 0.52 cm (p < 0.001). The rectal sensation improved post-A compared with pre-A. Comparing anorectal physiology results of ALTAS and TAR treatments, no differences in defecography and rectal sensation were detected pre- and post-treatment. However, in terms of anorectal manometry, the mean resting pressure and maximal squeezing pressure showed statistical difference with two treatments.
CONCLUSIONS
ALTAS treatment is a feasible option resulting in rapid and effortless long-term outcome, with low rates of complications. Therefore, this treatment may be an effective alternative for patients with symptomatic rectocele.
