Maladie de Hirschsprung à forme iléocolique associée à une malrotation intestinale

Hirschsprung disease in an adult with intestinal malrotation and volvulus: an exceptional association

Background

Hirschsprung disease is a neonatal discovery in almost all cases, and the association of Hirschsprung disease in adults with symptomatic intestinal malrotation is unusual. This combination delays diagnosis and can lead to mistake in surgical strategy.

Case presentation

A 43-year-old patient with a history of colectomy for colonic inertia and megadolichocolon was admitted to the Carcassonne Hospital emergency room for a volvulus of small bowel obstruction in a chronic intestinal obstruction context with episodes of acute, variable-looking occlusive syndromes. Intestinal malrotation was discovered during surgical small bowel detorsion. The acute occlusion syndrome recurred after the procedure. In view of the unfavorable evolution, an emptying of the dilated small bowel and a discharge ileostomy upstream of the rectum were performed. In the face of postoperative improvement, rectal manometry and deep full parietal rectal biopsies made it possible to highlight the diagnosis of Hirschsprung disease. The patient thus had functional acute occlusive syndromes and chronic occlusion due to Hirschsprung disease of attenuated form and acute organic occlusive syndromes related to her incomplete common mesentery.

Conclusions

This rare association, which may be responsible for delayed diagnostic and therapeutic wandering, highlights the importance of performing manometry and deep full parietal biopsies before a colectomy for colonic inertia, as well as the possibility of suggesting a common Hirschsprung disease and/or mesentery in an adult with multiple occlusive syndromes of variable appearance.

Rare Association of Extended Total Colonic Aganglionosis and Intestinal Malrotation

Total colonic aganglionosis occurring together with malrotation is a rare occurrence and may pose diagnostic and management dilemmas for the paediatric surgeon. We report a case of a neonate that presented with extended total colonic aganglionosis and malrotation, along with a spectrum of central nervous system and renal abnormalities. The clinical and radiological features and potential diagnostic and management pitfalls are discussed along with a literature review of this exceptionally infrequent association.

Midgut malrotation and associated Hirschsprung's disease: a diagnostic dilemma

Malrotation and Hirschsprung's disease (HSD) are rarely reported together. We report our experience with three patients who presented during the neonatal period in whom the association resulted in diagnostic difficulty. In this report, we focus on the clinical presentation, diagnosis and appropriate management.

Imperforate anus, malrotation, and Hirschsprung's disease: a rare and important association

Imperforate anus and malrotation rarely occur together. The conjoint occurrence of these with Hirschsprung's disease is exceedingly rare, but failure to recognize its existence may lead to catastrophic results. We present a case in which awareness to this possibility caused early detection and avoidance of possible complications.

The contribution of associated congenital anomalies in understanding Hirschsprung's disease

Hirschsprung's disease (HSCR) is a complex congenital disorder which, from a molecular perspective, appears to result due to disruption of normal signalling during development of enteric nerve cells, resulting in aganglionosis of the distal bowel. Associated congenital anomalies occur in at least 5-32% (mean 21%) of patients and certain syndromic phenotypes have been linked to distinct genetic sites, indicating underlying genetic associations of the disease and probable gene-gene interaction in its pathogenesis. Clear-cut associations with HSCR include Down's syndrome, dominant sensorineural deafness, Waardenburg syndrome, neurofibromatosis, neuroblastoma, phaeochromocytoma, the MEN type IIB syndrome and other abnormalities. Individual anomalies vary from 2.97% to 8%, the most frequent being the gastrointestinal tract (GIT) (8.05%), the central nervous system (CNS) and sensorineural anomalies (6.79%) and the genito-urinary tract (6.05%). Other associated systems include the musculoskeletal (5.12%), cardiovascular systems (4.99%), craniofacial and eye abnormalities (3%) and less frequently the skin and integumentary system (ectodermal dysplasia) and syndromes related to cholesterol and fat metabolism. In addition to associations with neuroblastoma and tumours related to MEN2B, HSCR may also be associated with tumours of neural origin such as ganglioneuroma, ganglioneuroblastoma, retinoblastoma and tumours associated with neurofibromatosis and other autonomic nervous system disturbances. The contribution of the major susceptibility genes on chromosome 10 (RET) and chromosome 13 (EDNRB) is well established in the phenotypic expression of HSCR. Whereas major RET mutations may result in HSCR by haploinsufficiency in 20-25% of cases, the etiology of the majority of sporadic HSCR is not as clear, appearing to arise from the combined cumulative effects of susceptibility loci at critical genes controlling the mechanisms of cell proliferation, differentiation and maturation. In addition, potential "modifying" associations exist with chromosome 2, 9, 20, 21 and 22, and we explore the importance of certain flanking genes of critical areas in the final phenotypic expression of HSCR.
