Retrospective cohort describes anatomical tailoring of surgical approaches for cloaca in 20 pediatric patients

A retrospective cohort study at Cairo University Specialized Pediatric Hospitals examined surgical approaches for cloaca in 20 pediatric patients. The study described how surgical techniques were tailored to anatomical characteristics, specifically vaginal depth and common channel length, without reporting clinical outcomes or having a control group.

Based on anatomical findings, 4 cases with vaginal depth >2 cm and long common channels (>3 cm) received one-stage laparoscopic rectal and vaginal pull-through. For 6 cases with vaginal depth >2 cm and short common channels (<3 cm), single-stage posterior sagittal anorectovaginourethroplasty was performed. The remaining 10 cases with vaginal depth <2 cm underwent a staged approach with initial colostomy and later vaginal reconstruction.

Safety and tolerability data were not reported. The study has several limitations: it is retrospective and descriptive with no outcomes data, has a small sample size of 20 patients, lacks statistical comparisons, and represents a single-center experience. No funding or conflict of interest information was provided.

This study describes associations between anatomical characteristics and surgical approaches in a specific cohort but does not establish causation or compare effectiveness. The practice relevance is limited to describing one center's approach to anatomical tailoring without evidence of superior outcomes. Clinicians should interpret these findings cautiously given the absence of outcome data and the study's descriptive nature.
