Introduction And Hypothesis:
The present study aimed to assess the changes in manometric parameters after transperineal repair (TPR) of rectocele and interpret failure of symptom improvement in light of these changes.
Methods:
This was an observational cohort study on patients with anterior rectocele who underwent TPR in the period of February 2016 to February 2019. Data collected included patients' demographics, rectocele size, Wexner constipation and incontinence scores, anal pressures, and rectal sensation before and 12 months after TPR. Analysis of data was done by paired t-test and chi-square test.
Results:
Forty-six female patients with a mean age of 43.2 ± 10.7 years were included. After a mean follow-up of 13.9 ± 2.7 months, 30 (65.2%) patients reported clinical improvement and 16 (34.8%) had no significant improvement. At 12 months after rectocele repair, the entire cohort studied showed an insignificant increase in the mean anal pressures and a significant decrease in the thresholds of first rectal sensation, first urge, intense urge, and maximum tolerable volume (MTV). Patients who clinically improved showed similar physiologic changes to the entire cohort examined, whereas patients who had no clinical improvement showed significant increases in the mean anal pressures and insignificant decreases in rectal sensation and MTV.
Conclusion:
Patients who showed clinical improvement showed insignificant increases in anal pressures and significant decreases in thresholds of first rectal sensation, first urge, intense urge, and MTV. Contrarily, patients who did not show clinical improvement showed significant increases in anal pressures and insignificant reduction in sensory thresholds.
