Apprehension regarding vaginal delivery in pregnant individuals with IBD persists due to concern for perianal disease and perineal trauma. The incidence of poor wound healing after obstetric anal sphincter injury is approximately 4% in the general population. In an IBD population, risk of developing and difficulty healing perineal tears and episiotomy is not well described.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>In a multicenter prospective cohort of pregnant individuals with IBD, we collected demographic information, IBD disease and treatment history, pregnancy and labor history, and reports of delayed wound healing &amp;gt;1 month from episiotomy, vaginal tear, or Cesarean (C-) section. Prospective data were collected using questionnaires that were administered each trimester of pregnancy, at delivery, and in the year postpartum.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>There were 743 patients in the PIANO registry who answered questions pertaining to postpartum wound healing, with 330 (44%) reporting a C-section and 413 (56%) reporting a vaginal delivery. Of 119 C-section deliveries assessed for delayed wound healing, only 1 (0.8%) patient reported this complication. Episiotomies were reported in 59 (14%) patients, with 9 (15%) reporting delayed wound healing. Vaginal tears were reported in 252 (64%) patients. Delayed wound healing from vaginal tear was reported in 9% of patients. Use of immunomodulators was associated with delayed wound healing from episiotomy (33% vs 0% for those on no medications, P\u2005=\u2005.024). No difference was seen in wound healing time for episiotomy with other medications, including corticosteroids, anti-tumor necrosis factor, or anti-integrin use. Delayed wound healing from vaginal tear was not associated with any class of IBD medication.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Episiotomy was a common occurrence in patients with IBD. Immunomodulator, but not biologic, use was found to be associated with delayed wound healing. This association could reflect a direct medication effect on episiotomy wound healing or inadequate treatment of underlying active disease prior to delivery. Vaginal tears were also common but delayed wound healing was not associated with IBD therapy. C-section occurred at high rates, particularly in Crohn\u2019s disease patients, with no reported delays in postpartum wound healing.<\/jats:p>\n
