妊娠中の巨大子宮頸部脱落膜ポリープ：結紮、ラクトフェリン、プロバイオティクスによる管理：症例報告

Giant cervical decidual polyps during pregnancy increase the risk of miscarriage and preterm delivery; however, optimal management has not yet been established. We report the case of a pregnant woman who presented at 11 weeks of gestation with a bleeding 4-cm cervical polyp. Oral lactoferrin and probiotics (Clostridium butyricum, Enterococcus faecium, and Bacillus subtilis) were administered. The polyp stalk near the external cervical os was ligated with triclosan-coated polydioxanone, resulting in necrosis and removal at 13 weeks, with complete resolution by 14 weeks. Vaginal Lactobacillus spp. increased and cervicitis resolved by 20 weeks without the use of antibiotics, despite the presence of Ureaplasma and/or Mycoplasma in vaginal secretions. The patient delivered a healthy infant at 40 weeks. This case highlights a minimally invasive strategy-polyp ligation combined with lactoferrin and probiotics-to help restore vaginal homeostasis, avoid the use of antibiotics, and achieve a favorable pregnancy outcome.
