Bowel Management in Hirschsprung Disease—Pre-, Peri- and Postoperative Care for Primary Pull-Through

Background: Total colonic aganglionosis, as a rare variant of Hirschsprung Disease, still poses challenges to surgeons in terms of diagnosis and management. The optimal preparation for pullthrough is crucial for reconstructive surgery. This study aims to explore our surgical pathway for children with total colonic aganglionosis (TCA) and to describe the prehabilitation necessary to prepare for successful reconstructive pullthrough surgery. Methods: A prospective review of children with TCA receiving an abdominal surgical intervention between 1/22 and 4/24. The cohort included children receiving mapping +/− primary ileoanal pullthrough. An analysis of preoperative, perioperative, and postoperative data, and a short-term follow-up were performed. Results: A total of 18 children with TCA and no prior pullthrough received an abdominal intervention during the 29-month study period, and 5/18 (27.8%) were female. The children had a median of 4 (range 2–7) prior external surgeries; all had a stoma; 6 (33%) children received parental nutrition; 12 children underwent a mapping of the ganglia distribution and bowel length at a median age of 11 months (range 3–54), and in 10 of them, we relocated the stoma. There was a mean involvement of 15 (5–93) cm small bowel aganglionosis, with the remaining mean ganglionic small bowel having a length of 178 cm (110–254). A total of 11 children underwent straight primary ileoanal pullthrough of the stoma site at a median age of 16.7 months (10–133). Conclusions: The timely diagnosis of TCA still challenges the care team, and most children have a rough journey involving several surgeries until their diagnosis is established. The ensure bowel function with an adequate working stoma is the key to enabling enteral nutrition and growth, which are the baseline requirements to undertake a successful pullthrough procedure and restore continuity. Careful perioperative bowel management and parents’ active involvement supports children with Hirschsprung Disease achieving the best possible quality of life.

Background: Constipation and outlet obstruction may persist after successful pull-through in Hirschsprung Disease (HD). The radiographic assessment of the faecal load is widely used but exposes the child to radiation. This study aims to evaluate whether the transrectal diameter (TRD) assessed with ultrasound correlates with symptoms of faecal load and whether the TRD normalises when symptoms disappear. Method: Children with HD after pullthrough and functional constipation presenting to our colorectal clinic between 4/23 and 4/24 were assessed for symptoms of constipation, smearing and outlet obstruction, as well as healthy controls. Ultrasound measurement of the TRD was conducted. Bowel management was initiated according to our institutional pathway using Peristeen© irrigation after an orthograde disimpaction regime. Results: A total of 193 children underwent TRD assessment. Of 60 children with HD, 26 (43.3%) presented with obstructive symptoms, and 34 (56.7%) were asymptomatic. In asymptomatic patients with HD, the mean TRD of 2.26 cm (SD 0.61) was significantly (p < 0.001) lower than in HD with symptoms, with a mean TRD of 3.35 cm (SD 1.03). Individuals without colorectal pathology had a mean TRD of 2.04 cm (SD 0.37), and children with functional constipation and symptoms showed a mean TRD of 4.36 cm (SD 1.32). The mean TRD after symptom resolution was 2.37 cm. Conclusions: Children with HD without obstructive symptoms have a TRD < 3 cm, as do controls. The transrectal diameter allows the clinician to sonographically assess the faecal load in children with HD at the bedside without radiation. The TRD is useful for monitoring a bowel management program in children with HD.

The Role of Patient Organisations—Patients’ and Parents’ Views and Experience of Hirschsprung’s Disease

In many countries, patient organisations offer advice and the exchange of experiences to Hirschsprung’s disease patients and their families. Professional treatment by experienced health care providers and the availability of life-long multidisciplinary follow-up care are essential. However, outside the clinic, patients and their families have to manage life on a day-to-day basis at home, which often brings up uncertainties and questions: Parents go through different stages during the diagnosis and treatment of their child, the affected children themselves go through many different stages of development, and even through the course of adulthood, new questions regarding the chronic disease may arise. Patient organisations can support the patients and their families at all stages of life by listening, offering information in an understandable way, connecting people, and sharing others’ experiences. This enables families and patients to develop a better understanding of the rare disease and promotes their management strategies and confidence. The holistic approach of patient organisations aims to complement the medical treatment. Therefore, the referral of all patients and their families to patient organisations should be part of the medical advice in the treatment of Hirschsprung’s disease.
