ABSTRACT
BACKGROUND: The recent American College of Obstetricians and Gynecologists Practice Bulletin offers no guidance on the management of preeclampsia with severe features at <24 weeks of gestation. Historically, immediate delivery was recommended because of poor perinatal outcomes and high maternal morbidity. Recently, advances in neonatal resuscitation have led to increased survival at periviable gestational ages. OBJECTIVE: This study aimed to report perinatal and maternal outcomes after expectant management of preeclampsia with severe features at <24 weeks of gestation. STUDY DESIGN: This was a retrospective case series of preeclampsia with severe features at <24 weeks of gestation at a level 4 center between 2017 and 2023. Individuals requiring delivery within 24 hours of diagnosis were excluded. Perinatal and maternal outcomes were analyzed. Categorical variables from our database were compared with previously published data using chi-square tests. RESULTS: A total of 41 individuals were diagnosed with preeclampsia with severe features at <24 weeks of gestation. After the exclusion of delivery within 24 hours, 30 individuals (73%) were evaluated. The median gestational age at diagnosis was 22 weeks (interquartile range, 22-23). Moreover, 16% of individuals had assisted reproductive technology, 27% of individuals had chronic hypertension, 13% of individuals had pregestational diabetes mellitus, 30% of individuals had previous preeclampsia, and 73% of individuals had a body mass index of >30 kg/m2. The median latency periods at 22 and 23 weeks of gestation were 7 days (interquartile range, 4-23) and 8 days (interquartile range, 4-13). In preeclampsia with severe features, neonatal survival rates were 44% (95% confidence interval, 3%-85%) at 22 weeks of gestation and 29% (95% confidence interval, 1%-56%) at 23 weeks of gestation. There were 2 cases of acute kidney injury (7%) and 2 cases of pericardial or pleural effusions (7%). Overall perinatal survival at <24 weeks of gestation was 30% in our current study vs 7% in previous reports (P=.02). CONCLUSION: For cases of expectant management of preeclampsia with severe features at <24 weeks of gestation, our findings showed an increased perinatal survival rate with decreased maternal morbidity compared with previously published data. This information may be used when counseling on expectant management of preeclampsia with severe features at <24 weeks of gestation.
ABSTRACT
BACKGROUND: Abdominal wall reconstruction (AWR) is one of the most commonly performed procedures, yet large comparative studies comparing outcomes of AWR using bovine acellular dermal matrix (BADM) and porcine acellular dermal matrix (PADM) are lacking. METHODS: In this retrospective cohort study of patients who underwent AWR from March of 2005 to June of 2019, the primary comparative outcome measure was hernia recurrence with BADM versus PADM. The secondary outcome was the incidence of surgical-site occurrence (SSO) and surgical-site infection. A propensity score matching approach was applied to compare the clinical outcomes between the two study groups. RESULTS: The authors identified 725 patients who underwent AWR using BADM (50.5%) or PADM (49.5%). Their mean ± SD age was 59.8 ± 11.5 years, mean body mass index was 31.4 ± 6.7 kg/m 2 , and mean follow-up time was 42 ± 29 months. With propensity score matching, 219 matched pairs were identified. Hernia recurrence rates in BADM (11.4%) and PADM (13.7%) groups did not differ significantly ( P = 0.793). SSO (26.5% versus 29.2%; P = 0.518) and SSI (13.2% versus 11%; P = 0.456) rates did not differ significantly in the PADM and BADM groups, respectively. Conditional logistic regression model and marginal Cox proportional hazards regression model determined that type of acellular dermal matrix was not significantly associated with SSOs (adjusted OR, 1.11; 95% CI, 0.74 to 1.70; P = 0.589) or hernia recurrence (adjusted hazard ratio, 0.85; 95% CI, 0.50 to 1.42; P = 0.52). CONCLUSIONS: Both BADMs and PADMs provide durable, long-term outcomes. The hernia recurrence and postoperative surgical complication rates were not significantly different between BADM and PADM. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
