Abstract
AbstractAimExtended total colonic aganglionosis (ETCA) represents uncommon forms of Hirschsprung disease (HD), with aganglionosis extending into the proximal small bowel. ETCA management is challenging and associated with poor outcomes and high mortality. This study compares management and outcomes of ETCA to more common HD forms.MethodsA retrospective cohort of HD patients (2012–2023) from two institutions. Three HD forms were compared: short‐segment HD (SSHD, n = 19), long‐segment HD or total colonic aganglionosis (LS/TCA, n = 9) and ETCA (n = 7).ResultsNormally innervated segments in ETCA patients ranged 0–70 cm. Median times to first surgery were; ETCA = 3 days versus TCA = 21 days (p = 0.017) and SSHD = 95 days (p < 0.001), respectively. Median number of surgeries were; ETCA = 4, versus TCA = 2 (p = 0.17) and SSHD = 1 (p = 0.002), respectively. All the patients underwent a definitive pull‐through procedure, except four ETCA patients with a permanent jejunostomy and residual aganglionic segment of 57–130 cm. ETCA patients had 92% lower odds of enterocolitis (14%) compared to TCA patients (67%, p = 0.054), and comparable odds to SSHD patients (16%, p = 0.92). ETCA mortality was 14%.ConclusionExtended total colonic aganglionosis patients require earlier and multiple interventions. Leaving an aganglionic segment may be advantageous, without increasing risk for enterocolitis. Tailored surgical treatment and rehabilitation programmes may prevent mortality and need for transplantation.
