Access to healthcare can facilitate parents’ self-management of their children’s care. Healthcare access can be described as consisting of six dimensions: approachability, acceptability, affordability, availability, appropriateness, and aperture. The aim of this study was to analyse these dimensions of healthcare access experienced by parents caring for their children at home following paediatric surgery. The method-directed content analysis, conducted with the six-dimensional framework of access to healthcare as a guide, was used to analyse twenty-two interviews with parents of children treated with paediatric surgery. All six dimensions were represented in the results. Acceptability was the most frequent dimension, followed by appropriateness and approachability. Affordability, availability, and aperture were less represented. Although access to healthcare after paediatric surgery is generally appropriate and approachable, parents may experience insecurity in performing the self-management needed. Complementary forms of information provision, e.g., telemedicine, can be valuable in this regard.

Hirschspung’s disease (HD) is a congenital gastrointestinal (GI) disorder frequently accompanied by GI complaints. Despite the lack of evidence regarding whether diet affects GI symptoms, advice on dietary changes is common. The aim was to investigate self-reported dietary effects on GI symptoms, comparing children with HD with healthy children. This was an observational, cross-sectional, self-reported case-control study using the validated Diet and Bowel Function questionnaire. All children with HD aged 1–18 years were surgically treated during 2003–2021 at a national HD center, and their parents were invited to participate. Healthy children served as controls. The data were presented as median (range) and n (%). 71/85 children with HD (6 years (1–17); 76% boys) and 265/300 controls (9 years (1–18); 52% boys) participated. Dietary effects on GI symptoms were reported more frequently by children with HD than controls (55/71 [77%] vs. 137/265 [52%], p ≤ 0.001), as were dietary adjustments to improve GI symptoms (49/71 [69%] vs. 84/265 [32%], p ≤ 0.001), and social limitations due to dietary adjustments (20/48 [42%] vs. 22/121 [18%], p = 0.002). Of 90 food items, children with HD reported that more of the items induced GI symptoms compared to controls (7 (0–66) vs. 2 (0–34), p = 0.001). Diet-induced GI symptoms and dietary adjustments’ impact on daily life are reported more frequently by children with HD than controls. Moreover, the number and types of food items causing GI symptoms differ. The results indicate the need for disease-specific dietary advice to improve support for families of children with HD.

Ultra-high-frequency ultrasound (UHFUS) has a reported potential to differentiate between aganglionic and ganglionic bowel wall, referred to as histoanatomical differences. A good correlation between histoanatomy and UHFUS of the bowel wall has been proven. In order to perform more precise and objective histoanatomical morphometrics, the main research objective of this study was to develop a computer program for the assessment and automatic calculation of the histoanatomical morphometrics of the bowel wall in UHFUS images. A computer program for UHFUS diagnostics was developed and presented. A user interface was developed in close collaboration between pediatric surgeons and biomedical engineers, to enable interaction with UHFUS images. Images from ex vivo bowel wall samples of 23 children with recto-sigmoid Hirschsprung’s disease were inserted. The program calculated both thickness and amplitudes (image whiteness) within different histoanatomical bowel wall layers. Two observers assessed the images using the program and the inter-observer variability was evaluated. There was an excellent agreement between observers, with an intraclass correlation coefficient range of 0.970–0.998. Bland–Altman plots showed flat and narrow distributions. The mean differences ranged from 0.005 to 0.016 mm in thickness and 0 to 0.7 in amplitude units, corresponding to 1.1–3.6% and 0.0–0.8% from the overall mean. The computer program enables and ensures objective, accurate and time-efficient measurements of histoanatomical thicknesses and amplitudes in UHFUS images of the bowel wall. The program can potentially be used for several bowel wall conditions, accelerating research within UHFUS diagnostics.
