Pregnancy and stomas: a 9-year retrospective series at a major metropolitan hospital in Brisbane Queensland

Abstract

Background

Over 42 000 Australians live with a stoma, and this number increases annually. Pregnancy in stoma patients is a rare but complex condition and there is limited published literature regarding surgical and obstetric complications in pregnant stoma patients. The aim of this paper was to review stoma outcomes, perinatal morbidity and mortality, and early postpartum period in pregnant stoma patients.

Methods

Data was retrospectively obtained on women of childbearing age, with a stoma, who had been pregnant and birthed in the last nine years at the Royal Brisbane and Women's Hospital between January 2014 to December 2022. Data recorded included patient demographics, type of stoma, indication for stoma, need for additional abdominal surgeries, method of conception, pregnancy complications, length of stay, neonatal outcomes and post pregnancy stomal complications.

Results

In total, there were 16 births from 13 mothers with stomas. Of 10 births to IBD patients, 40% experienced a serious stomal complication. Caesarean section (CS) rate was 90% for IBD and 83% for non-IBD. In-vitro fertilisation rates were 40% in IBD patients and 0% in non-IBD patients. The average gestational age at delivery was 36 weeks in IBD and 35 weeks in non-IBD patients. Neonates delivered to IBD mothers had a birth weight under 2500g in 40% of cases and in non IBD mothers at 33.3% (p = 0.62). Of the sixteen births there was five complications (31.25%) associated with the stoma either during pregnancy or during the sixty-day postpartum period.

Conclusion

Pregnancy in stoma patients is a rare occurrence and appears to be associated with high rates of CS, preterm delivery, low birth weight and stomal complication.
