The dual-staged pathway for closure in cloacal exstrophy: Successful evolution in collaborative surgical practice

Area of Science:

• Pediatric Surgery
• Urology
• Developmental Biology

Background:

• Successful abdominal wall and bladder closure are crucial for managing cloacal exstrophy (CE).
• This study evaluates closure outcomes over four decades, focusing on the implementation of the Dual-Staged Pathway (DSP) in 1995.
• The DSP involves staged bladder closure, osteotomy, and external fixation for CE management.

Purpose of the Study:

• To compare the outcomes of cloacal exstrophy (CE) closures before and after the standardization of the Dual-Staged Pathway (DSP).
• To assess the efficacy and safety of the DSP in managing CE patients.

Main Methods:

• A retrospective review of 1332 Exstrophy-Epispadias Complex (EEC) patients, focusing on 49 CE patients with 50 closures between 1975 and 2015.
• Comparison of closure outcomes between two 20-year periods: pre-DSP (1975-1994) and post-DSP implementation (1995-2015).
• Data collected included timing of closure, postoperative management, complications, and outcomes. The study was a Level III retrospective comparative study.

Main Results:

• The DSP achieved a 100% closure success rate (34 patients) compared to 88% in the pre-DSP era (16 patients).
• Overall complication rates were similar between the two periods (29% for DSP vs. 19% previously).
• Patients referred after DSP implementation had significantly larger pre-closure diastasis (7.2 cm vs. 5.1 cm).

Conclusions:

• The standardized Dual-Staged Pathway (DSP) has demonstrated a 100% success rate in 34 primary and reoperative cloacal closures over 20 years.
• The DSP approach is associated with improved patient safety and better outcomes in cloacal exstrophy management.
• The DSP is a successful and safe standardized method for cloacal exstrophy closure.
