Abstract

© 2018 Elsevier Inc. Introduction: Acquired skin-level strictures following posterior sagittal anorectoplasty (PSARP) and some rare cases of congenital anal stenosis can be managed using a Heineke–Mikulicz like anoplasty (HMA). We hypothesized that this procedure was an effective, safe, and durable outpatient procedure in select patients. Methods: We retrospectively reviewed all patients who underwent HMA for skin level strictures following PSARP or for certain congenital anal stenoses from 2014 to 2017. Results: Twenty-eight patients (19 males, 9 females) with a mean age of 5.8 years (range 0.5–24.4) underwent HMA. Twenty-six had a prior PSARP, of which 18 were redo, and 8 were primary procedures. Two patients had congenital skin level anal stenosis. The mean follow up was 1.0 years (range 0.4–2.9). The average preprocedure anal size was Hegar 8, which after HMA increased 8 Hegar sizes to 16 (95% CI 7–9, p < 0.001). There were no operative complications. One patient restenosed and required a secondary procedure. Conclusion: HMA is a safe procedure for skin-level anal strictures following PSARP (primary and redo) and can also be used in some rare cases of congenital anal stenosis. Long-term follow up to determine the restricture rate is ongoing. A plan to do an HMA if a stricture develops may offer an alternative to routine anal dilations, particularly after a redo PSARP in an older child. Type of study: Case series. Level of evidence: Level IV.
