dc.description.abstract | The relationship between the anorectal angle (ARA) and the levator ani muscle (LAM) is
well known. In this study, we aimed to demonstrate that the ARA changes when LAM avulsion
occurs after vaginal delivery. This was a secondary, observational retrospective study with data
obtained from three previous studies. Using transperineal ultrasound, the presence of avulsion was
assessed when abnormal insertion of the LAM was observed in three central slices. In addition, the
ARA was assessed in the midsagittal plane (at rest, in Valsalva and at maximum contraction) as the
angle between the posterior border of the distal part of the rectum and the central axis of the anal
canal. The ARA was higher in patients with bilateral LAM avulsion than in patients without LAM
avulsion at rest (131.8 ± 14.1 vs. 136.2 ± 13.8), in Valsalva (129.4 ± 15.5 vs. 136.5 ± 14.4) and at
maximum contraction (125.7 ± 15.5 vs. 132.3 ± 13.2). The differences between both groups expressed
as the odds ratio (OR) adjusted for maternal age were 1.031 (95% confidence interval (CI), 1.001–1.061;
p = 0.041) at rest, 1.036 (95% CI, 1.008–1.064; p = 0.012) in Valsalva and 1.031 (95% CI, 1.003–1.059;
p = 0.027) at maximum contraction. In conclusion, LAM avulsion produces an increase in the ARA at
rest, during contraction and in Valsalva, especially in cases of bilateral LAM avulsion. | es |
