OBJECTIVE: To explore the association of delivery mode and the number of pregnancies with anorectal manometry data in patients with postpartum constipation.
METHODS: This retrospective study included women with postpartum constipation treated at the pelvic floor rehabilitation department of Huzhou Maternity & Child Health Care Hospital between January 2018 and December 2019.
RESULTS: Among 127 patients included, 55 (43.3%) had one pregnancy, 72 (56.7%) had two pregnancies, 96 (75.6%) delivered spontaneously, 25 (16.7%) underwent Cesarean section, and six (4.7%) needed a Cesarean section despite spontaneous labor. The median duration of constipation was 12 months (range, 6-12). There were no differences between the two groups for any manometry parameters (all P > 0.05). The patients with a spontaneous delivery had a lower change in maximal contracting sphincter pressure compared with those with Cesarean section (14.3 (4.5-25.0) vs. 19.6 (13.4-40.0), P = 0.023). Only the delivery mode (Cesarean vs. spontaneous) independently affected the changes in contracting sphincter pressure (B = 10.32, 95%CI: 2.95-17.69, P = 0.006); age (P = 0.201), number of pregnancies (P = 0.190), and constipation duration (P = 0.161) were not associated.
CONCLUSION: The patients with a spontaneous delivery had a lower change in maximal contracting sphincter pressure compared with those with a Cesarean section, suggesting that patients with Cesarean may retain a better "push" function during defecation.
