Difficulties in making the diagnosis of Hirschsprung disease in early infancy

Diagnosing Hirschsprung Disease in Children Younger than 6 Months of Age: Insights in Incidence of Complications of Rectal Suction Biopsy and Other Final Diagnoses

BACKGROUND

 The gold standard for diagnosing Hirschsprung disease (HD) in patients younger than 6 months is pathological examination of rectal suction biopsy (RSB). The aim of this study was to gain insight into the following: (1) complications following RSB, (2) final diagnosis of patients referred for RSB, and (3) factors associated with HD.

METHODS

 Patients suspected of HD referred for RSB at our center were analyzed retrospectively. Severity of complications of RSB was assessed using Clavien-Dindo (CD) grading. Factors associated with HD were tested using multivariate logistic regression analysis.

RESULTS

 From 2000 to 2021, 371 patients underwent RSB because of infrequent defecation, at a median age of 44 days. Three patients developed ongoing rectal bleeding (0.8%) graded CD1. Most frequent final diagnoses were: HD (n = 151, 40.7%), functional constipation (n = 113, 31%), idiopathic meconium ileus (n = 11, 3%), and food intolerance (n = 11, 3%). Associated factors for HD were male sex (odds ratio [OR], 3.19; confidence interval [CI], 1.56-6.53), presence of syndrome (OR, 7.18; CI, 1.63-31.69), younger age at time of RSB (OR, 0.98; CI, 0.85-0.98), meconium passage for more than 48 hours (OR, 3.15; CI, 1.51-6.56), distended abdomen (OR, 2.09; CI, 1.07-4.07), bilious vomiting (OR, 6.39; CI, 3.28-12.47), and failure to thrive (OR, 8.46; CI, 2.11-34.02) (model R 2 = 0.566).

CONCLUSION

 RSB is a safe procedure with few and only minor complications. In the majority of patients referred for RSB under the age of 6 months, HD was found followed by a functional cause for the defecation problems. RSB should be obtained on a low threshold in all patients under the age of 6 months with the suspicion of HD.

Parental Concerns on Gastroesophageal Reflux

Parents often perceive infant gastroesophageal reflux (GER) as a serious problem. Frequently, GER is explained as a normal process, but there are instances where parents’ concerns are valid. Provided are 3 case studies from the private practice of an IBCLC. Each case initially presented with what sounded like normal infant GER. Upon further evaluation, with close follow-up and more detailed history taking, each case required advanced medical attention. These cases highlight the unique role of the IBCLC in helping to assess GER, the value of working as a team member with baby’s physicians, and the importance of listening carefully to parental instincts and concerns.

Diagnosis of Hirschsprung's disease with particular emphasis on histopathology. A systematic review of current literature

Hirschsprung's disease (HD) is a disorder that involves several medical specialties such as paediatric gastroenterology, paediatric surgery, and pathology. Hirschsprung's disease is a congenital bowel innervation disorder characterised by the absence of ganglion cells in myenteric (Auerbach) and submucosal (Meissner) plexus in the distal colon in its classical form. Rapid and accurate diagnosis of HD is a key element in further treatment patterns. The efficiency of different diagnostic methods used in HD patients may vary. Using one limited diagnostic procedure can lead to as much as a few per cent of overlooked cases. In recent years, rectal biopsy was recognised as an important diagnostic tool that allows for a definitive HD diagnosis with an accuracy of 95% of cases. A correct diagnosis depends on the localisation of the biopsied sample, its representativeness, the number of specimens, and proper interpretation of microscopic studies supported by histochemical and immunohistochemical methods. When several methods are used and all diagnostic criteria are used, the diagnostic sensitivity can almost eliminate cases of undiagnosed patients.

Long-term outcomes and quality of life after subtotal colectomy combined with modified Duhamel procedure for adult Hirschsprung's disease

BACKGROUND

Subtotal colectomy combined with modified Duhamel procedure (Jinling procedure) was used in patients with adult Hirschsprung's disease (AHD) at Jinling Hospital in the last decade. The aim of this study is to evaluate the safety, effectiveness and quality of life of Jinling procedure for AHD.

MATERIALS AND METHODS

All the data are from the database of the Jinling Hospital Constipation Registry System. Primary outcomes, including safety (morbidity and adverse events), effectiveness (satisfaction rate, Wexner constipation scale (WCS) and bowel function score (BFS)) and gastrointestinal quality of life index (GIQLI), were all evaluated.

RESULTS

Fifty-nine patients were available for this study and the mean postoperative period was 44 months. Seventeen major complications were found in 11 patients and most of the complications could be managed conservatively. A significant improvement in WCS, BFS and GIQLI at 6 months postoperatively was obtained.

CONCLUSION

Jinling procedure is safe and effective for AHD.

Application of a plain abdominal radiograph transition zone (PARTZ) in Hirschsprung's disease

Background

A standard contrast enema for Hirschsprung's disease can sometimes be inconclusive in delineating a transition zone especially in neonates and infants. The aim of this study was to determine the utility and diagnostic accuracy of a plain abdominal radiograph transition zone (PARTZ) in predicting the level of aganglionosis.

Methods

A prospective observational study of neonates and infants with biopsy proven Hirschsprung's disease was carried out from March 2004 through March 2006. All patients underwent a plain abdominal radiograph and a contrast enema followed by a rectal biopsy. The transition zone on a plain radiograph (PARTZ) and contrast enema (CETZ) were compared with operative and pathology reports. Results were analyzed by chi square test and expressed as their p values and 95% confidence intervals.

Results

PARTZ and CETZ suggestive of Hirschsprung's disease was seen in 24(89%) and 18(67%) patients respectively. The PARTZ and CETZ matched with the pathologic level of transition zone in 22(92%) and 13(72%) patients, p = 0.001, 95% CI (-1.87 to -0.79). In the 9 (33%) patients in whom contrast enema failed to reveal a transition zone, PARTZ was seen in 6/9(66%) patients and correlated with the pathological level of aganglionosis in 4/6(67%) patients, p = 0.001 95% CI (-1.87 to -0.79). The overall accuracy of PARTZ and CETZ was 96% and 84% respectively, p = 0.008, 95% CI (-6.09 to -3.6).

Conclusion

A plain abdominal radiographic transition zone is reliable in predicting the level of transition zone in cases of inconclusive contrast enema. It may be particularly helpful developing countries where laparoscopic techniques are not available to accurately identify the transition zone.
