[Rates and histological characteristics of rectal polyps in childhood].

Aim Of Study: To determine a single centre incidence, rate of early and late complications and sequelae and histological characteristics of solitary rectosigmoideal polyps in children.

Methods: Retrospective analysis of hospital charts and histological characteristics of patients operated for rectosigmoideal polyps between January 1995 and December 2005. There were 23 children operated on, the study group consists of 20 patients (3 patients were excluded because of insufficient documentation).

The risk of medullary thyroid carcinoma in patients with Hirschsprung's disease.

Hirschsprung's disease (HD) can be associated with the development of neuroendocrine tumours such as medullary thyroid carcinoma (MTC). The RET proto-oncogene is the major gene responsible for both HD and MTC. Mutations in exon 10 (codons 609, 611, 618, 620) were found in patients with co-occurrence of HD and MTC.

Intestinal neuronal dysplasia.

Intestinal neuronal dysplasia type B (IND B) is currently defined as a disease of the submucous plexus of the intestine. The aetiology of IND B remains largely obscure. The congenital origin of IND B is supposed; nevertheless, the findings of IND B associated with chronic intestinal obstruction support the notion that this disease could be caused by a reaction of the enteral nervous system to intestinal obstruction or inflammatory disease either in the fetal or the postnatal period.

[The cystadenocarcinoma of the appendix].

The authors present a case-review of a patient with a large retroperitoneal tumor. A right-sided hemicolectomy with a removal of a large retroperitoneal cyst extending behind the liver up to the diaphragm on the right side, was conducted. Histology confirmed a mucous cystadenocarcinoma of the appendix.

[Transanal resection of the recto-sigmoid--the future in the treatment of classic Hirschsprung's disease?].

Introduction: The technique of transanal resection (TAR) of aganglionary part in rectosigmoid, published in 1998, has gradually become a standard operation technique in the treatment of Hirschsprung's disease (H.d.).
