Total colonic aganglionosis in Hirschsprung disease.
نویسنده
چکیده
Total colonic aganglionosis (TCA) is a relatively uncommon form of Hirschsprung disease (HSCR), occurring in approximately 2%-13% of cases. It can probably be classified as TCA (defined as aganglionosis extending from the anus to at least the ileocecal valve, but not >50 cm proximal to the ileocecal valve) and total colonic and small bowel aganglionosis, which may involve a very long segment of aganglionosis. It is not yet clear whether TCA merely represents a long form of HSCR or a different expression of the disease. There are many differences between TCA and other forms of HSCR, which require explanation if its ubiquitous clinical features are to be understood. Clinically, TCA appears to represent a different spectrum of disease in terms of presentation and difficulties that may be experienced in diagnosis, suggesting a different pathophysiology from the more common forms of HSCR. There is also some evidence suggesting that instead of being purely congenital, it may represent certain different pathophysiologic mechanisms. This study, in addition to reviewing current understanding and differences between TCA and the more frequently encountered rectosigmoid (or short-segment) expression, correlates them with what is currently known about the genetic and molecular biological background. Moreover, it reviews current outcomes to find consensus on management.

We present the case of a child with presumed total colonic Hirschsprung disease (HD) to highlight the problems the surgeon is likely to encounter if he/she relies on the appendix alone for histopathologic diagnosis. A newborn male infant, who was presumed to have total colonic aganglionosis when the appendix was found to be aganglionic at the time of initial exploratory laparoscopy, was managed...

We would like the authors to note the recent review on the subject in Lane et al. “The Appendix and Aganglionosis. A Note of Caution-How the Histology Can Mislead the Surgeon in Total Colonic Hirschsprung’s Disease”, [2] This report showed that the appendix is not reliable in determining whether there is Hirschsprung’s disease as many normal appendices have no ganglion cells. When we looked at ...
