1/2. anal canal duplication in infants and children--a series of 6 cases.The authors present a series of six anal canal duplications (ACD), duplications of the alimentary tract located along the posterior side of the anal canal, with a perineal opening just behind the anus. Five asymptomatic duplications were diagnosed before the age of one year, by simple perineal inspection. A twelve-year-old girl presented with perineal and anal pains and diarrhoea. Fistulography revealed a tubular structure in five cases and a cystic structure in one case, behind the normal anal canal, in one case communicating with it. A presacral sacrococcygeal teratoma was found in two children and in one case it was visualised by preoperative US in an infant with a lumbosacral myelomeningocele. Surgical excision was performed by a perineal approach in 5 cases, by a combined sacral and perineal approach in the last case, because of the associated teratoma. Non-invasive preoperative investigations, consisting of a pelvic X-ray, US examination, barium enema and fistulography, are sufficient in most cases; MRI is reserved for special indications. Surgical treatment restores a normal perineal aspect, without sequelae, and avoids complications like those described in other types of digestive duplications: infection, ulceration, bleeding, malignant changes during later adult life. Associated anomalies are frequently described in the literature, especially presacral tumours (16%) and anorectal malformations (21%); they can influence the management, the surgical approach and the functional prognosis.- - - - - - - - - - ranking = 1keywords = meningocele (Clic here for more details about this article) |
2/2. Congenital asplenia and anomalies of the gastrointestinal tract.Congenital asplenia has been traditionally described in association with cardiopulmonary anomalies (Ivemark syndrome). A case of congenital asplenia with duplication of the hindgut and genitourinary tract, myelomeningocele, situs inversus abdominis, and imperforate anus generated interest in review of the gastrointestinal anomalies of 36 patients who died of the disease in Childrens Hospital of los angeles. A significant number were found to have situs inversus, malrotation of the bowel, esophageal varices, duplication and hypoplasia of the stomach, Hirschsprung's disease, imperforate anus, and duplication of the hindgut. These patients present with symptoms referable to their gastrointestinal anomalies and may not draw attention to the concomitant cardiopulmonary anomalies or to the absence of the spleen. It becomes important, therefore, to establish the presence of the spleen in infants suffering from various anomalies of the gastrointestinal tract because of the overwhelming septicemia that is known to complicate the clinical management of these patients.- - - - - - - - - - ranking = 1keywords = meningocele (Clic here for more details about this article) |
