Importance of the early diagnosis of incarcerated gravid uterus: Case report and systematic review

To examine whether the early diagnosis of uterine incarceration before 20 weeks of gestation improves maternal-perinatal prognoses.A systematic review of all of the cases published in the past 30 years that met the inclusion and exclusion criteria was performed and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. A comparative analysis of diagnoses before and after 20 weeks of gestation was performed.Eighty-nine studies with a total of 146 cases of uterine incarceration during pregnancy were included. For cases of incarceration diagnosed before 20 weeks of gestation, a higher proportion of clinical symptoms was observed; however, a lower proportion of complications, such as premature delivery, need for cesarean section, and poor perinatal outcomes, were observed (P < 0.05). The proportion of spontaneous resolution and minimally invasive techniques for the treatment of incarceration was significantly higher among patients diagnosed with this pathology before 20 weeks (P < 0.05).The literature indicates that uterine incarceration is a rare complication during pregnancy with better maternal-perinatal results if diagnosed earlier than 20 weeks.
