Fetal ascites in cloacal malformations-a red flag

Area of Science:

• Pediatric Surgery
• Fetal Surgery
• Neonatal Care

Background:

• Cloacal malformation is a rare congenital anomaly challenging prenatal diagnosis.
• Ascites can be an isolated or associated finding, sometimes progressive, raising questions about antenatal intervention.
• Previous diagnostic modalities like ultrasonography and MRI have limitations in identifying this condition.

Purpose of the Study:

• To highlight the association between prenatal ascites and surgical complexity in cloacal malformation.
• To emphasize the need for specialized surgical and anesthetic preparedness for affected neonates.
• To underscore the importance of experienced teams in managing these challenging cases.

Main Methods:

• Retrospective review of ten patients diagnosed with cloacal malformation between 2010 and 2022.
• Analysis of prenatal findings, specifically the presence of ascites.
• Correlation of prenatal findings with intraoperative findings and outcomes.

Main Results:

• The presence of antenatal ascites in cloacal malformation cases was linked to extensive bowel adhesions.
• These adhesions significantly complicated the initial laparotomy and peri-operative management.
• Patients with ascites faced a higher risk of hemodynamic instability during surgery.

Conclusions:

• Antenatal detection of ascites in newborns with cloacal malformation warrants heightened surgical and anesthetic vigilance.
• Surgeons and anesthesiologists must anticipate operative difficulties stemming from bowel adhesions and potential hemodynamic instability.
• An experienced surgical team is crucial for successful initial laparotomy in these high-risk neonates.
