Abstract

Background: The type of osteotomy and pelvic fixation in the management of primary cloacal exstrophy (CE) closure is variable. The purpose of this study was to evaluate primary CE closure outcomes with osteotomy, immobilization, and multi-staging procedure trends over time. Methods: An institutional database was retrospectively reviewed for patients who underwent primary CE closure from 1960 to 2020. Demographics, osteotomy, fixation, and outcomes were noted. Subanalyses by location of primary closure (AH=author's hospital; OH=outside hospital). Results: Out of 122 patients, multi-stage became more common than single-stage procedures (p = 0.019), with multi-stage associated with higher success rates (77.4% v 45.7%; p = 0.001). The use of any osteotomy increased over time (p = 0.007), with a posterior approach falling out of favor and increasing prevalence of a combined osteotomy (p<0.001). The use of any osteotomy compared to no osteotomy was associated with successful closure (77.6% v 41.7%; p = 0.007). The combined, posterior, and anterior approaches were associated with 90%, 76.2%, and 60.9% successful primary closure rates, respectively (p<0.001). Fixation modalities changed over time as Buck's traction (p<0.001) and external fixation (p<0.001) became more prevalent. Spica casting has become less common (p = 0.0002). Immobilization type was associated with success rates with Buck's (92.1%; p<0.001) and external fixation (86.0%; p<0.001) performing best. Conclusions: The use of osteotomy and fixation in the CE spectrum has changed markedly. In this cohort, a staged approach with combination osteotomy was associated with better outcomes when using a multidisciplinary team approach.
