Late Diagnosis of Hirschsprung Disease: Clinical Presentation and Long-Term Functional Outcomes.

Abstract

PURPOSE:

Hirschsprung Disease (HD) is typically diagnosed in the neonatal period. A small subset of patients have a prolonged course of abdominal distention and constipation prior to diagnosis. Late HD is defined as having been diagnosed at greater than or equal to one year of age. The literature is limited and offers conflicting data on the implications of a late diagnosis. We aim to investigate the presentation, operative approach, and functional outcomes of a large cohort of patients with a late HD diagnosis.

METHODS:

All patients with a late diagnosis of HD (after 1 year of age) at our institution between 1997 and 2021 were included.

RESULTS:

Twenty-eight patients were diagnosed with HD at a median age of 3.4 years. Chronic constipation, failure to thrive, and enterocolitis occurred in 100 %, 31 %, and 14 %, respectively. All patients underwent contrast enema and biopsies during their workup, identifying primarily rectosigmoid disease (n = 27) and total colonic aganglionosis (n = 1). Surgical intervention was performed in 27 patients, with 4 patients (15 %) needing a stoma (3 with plan for staged pull-through, 1 long-term stoma) and 23 patients (85 %) undergoing a single-stage pull-through. Postoperative complications included Hirschsprung-associated enterocolitis (n = 5), ostomy prolapse and revision (n = 2), abdominal distention requiring ileostomy creation (n = 2), redo pull-through (n = 2), retroperitoneal hematoma (n = 1), and cecostomy tube placement (n = 1). At a median follow-up of 5.4 years, 83 % of eligible patients achieved fecal continence with 43 % needing laxatives for persistent constipation.

CONCLUSION:

Recognizing a late presentation of HD requires a high index of suspicion. Patients with a late diagnosis did not experience an increased rate of permanent stoma, complications, or redo surgery compared to rates reported for the larger HD population. Similar long-term functional outcomes were achieved compared to the larger HD population.
