Abstract

Introduction: Pediatric female genital trauma (PFGT) comprises injuries to the female external and internal genitalia. Examination under general anesthesia (GA) in the operating room (OR) is traditionally recommended, however repair at the bedside under conscious sedation (CS) in the emergency department (ED) may be a safe alternative. The Genitourinary Injury Score (GIS) objectively classifies PFGT severity, but designates all vaginal and urethral injuries as Grade III.

Objective: To compare outcomes and cost of patients with PFGT managed under CS in the ED vs GA in the OR.

Study design: All patients treated by a pediatric urologist from May 2009 to September 2019 with associated ICD codes for PFGT were included. Exclusion criteria included PFGT from sexual abuse or obstetric related complications. Clinical and demographic data was extracted from the EMR. A cost analysis comparing ED vs OR management was performed.

Results: 33 patients were identified with a median age of 6.8 years. The primary etiology was straddle trauma. Injuries were predominately GIS I-III (30, 91%) with possible urethral involvement in 6 patients. Sedation and repair in the ED was performed for 12 (36%) patients vs 21 (64%) taken to the OR. For the OR cohort, 15 (71%) were taken to the OR immediately and 6 (29%) initially underwent CS but this was aborted due to injury complexity. Aborting CS and proceeding to the OR did not result in compromised outcome or prolonged hospitalization. No patients in the ED cohort required post-procedural admission whereas all patients taken to the OR were admitted postoperatively. Cost of care for ED repair was less than two-thirds (60%) that of surgical repair in the OR. Using Onen GIS III or less without deep vaginal and/or urethral involvement as a cutoff for attempted bedside repair vs proceeding directly to the OR could have spared 7 (47%) patients GA and subsequent admission. A female-specific modification to the Onen GIS III criteria is proposed in light of these findings.

Discussion: The present study suggests CS and bedside repair of low-grade PFGTs is safe with a cost benefit. This is reflected by a proposed modification to the Onen GIS III criteria. These findings should be interpreted with caution given the retrospective nature of this single institution, small cohort study.

Conclusion: CS and bedside repair of low-grade PFGT appears to be safe and cost effective. Delineating GIS III injuries according to urethra and/or deep vaginal involvement may improve the GIS scale's clinical utility.
