Persistencia de conducto onfalomesenterico permeable / Patent onfalomesenteric conduct / Persistência do ducto onfalomesentérico permeável

La persistencia del conducto onfalomesentérico permeable es una de las formas de presentación menos frecuente, dentro de la patología, de los restos embrionarios derivados de este conducto. Se presenta el caso de un lactante de 30 días de vida a quien se le hace un diagnóstico de conducto onfalomesentérico permeable y se realiza cirugía resectiva, con una buena evolución postoperatoria inmediata y con alta a domicilio a los 8 días. Se revisan los datos de embriología así como de patología, la presentación clínica, los diagnósticos diferenciales y las opciones terapéuticas.

The persistence of permeable omphalosenteric duct is one of the less frequent forms of presentation, within the pathology, of the embryonic remnants derived from this duct. We present the case of a 30-day-old infant who is diagnosed with permeable omphalomesenteric duct, and resective surgery is performed, with a good postoperative evolution and with home discharge at 8 days. The embryology data as well as the pathology, the clinical presentation, the differential diagnoses and the therapeutic options are reviewed.

A persistência do ducto onfalossentérico permeável é uma das formas menos freqüentes de apresentação, dentro da patologia, dos remanescentes embrionários derivados desse ducto. Apresentamos o caso de um lactente de 30 dias que é diagnosticado comducto oncomumentérico permeável, sendo realizada cirurgia ressectiva, com boa evolução pós-operatória e com descarga domiciliar aos 8 dias. Os dados da embriologia, bem como a patologia, a apresentação clínica, os diagnósticos diferenciais e as opções terapêuticas são revisados.

Persistent Vitellointestinal Duct Causing Small Bowel Obstruction - A Rare Entity.

Vitellointestinal {omphalo-mesenteric (OMD)} duct connects the developing mid-gut to the primitive yolk sac, provides nutrition to the embryo and remains patent and connected to the intestines until the fifth to ninth week of gestational period. Varied remnants of the vitellointestinal duct have been reported. The present case report describes a completely obliterated fibrous remnant of the duct. The remnant presented as a thick cord extending from the umbilicus towards the terminal part of ileum with a Meckel’s diverticulum. Herein, we report a case of 20 yr old male who presented with the features of small bowel obstruction due to completely obliterated fibrous remnant of the duct which is a rare entity. Although persistent omphalomesentric duct is an extremely infrequent cause of small bowel obstruction in adult patients, it should be taken into consideration in patients without any previous surgical history.

Obstrucción intestinal por remanente onfalomesentérico obliterado en paciente adulto: reporte de un caso / Bowel obstruction caused by an omphalomesenteric duct remnant: report of one case

Omphalomesenteric duct remnant is one of the least common congenital abnormalities due to vitelline sac persistence. Among the five types of this abnormalities, omphalomesenteric band or obliterated omphalomesenteric duct remnant is the least common. We report a 64 years old male presenting with vomiting, abdominal pain and absence of stools. The patient was operated with the diagnosis of intestinal obstruction and a persistent omphalomesenteric duct that caused the bowel obstruction was found. The patient had an uneventful postoperative period as is discharged 24 hours later.

El remanente del conducto onfalomesentérico es una de las anomalías congénitas más raras asociadas con la permanencia del saco vitelino. Dentro de los cinco subtipos que se describen en la literatura, la banda onfalomesentérica o conducto onfalomesentérico obliterado es el de menor frecuencia. Presentamos un caso muy infrecuente de persistencia del conducto onfalomesentérico, que ocasionó una obstrucción intestinal en un paciente adulto y que fue resuelto de forma quirúrgica.

Persistencia del conducto onfalomesentérico / Patent omphalomesenteric duct

La persistencia del conducto onfalomesentérico es una de las formas de presentación más raras de los restos embrionarios derivados de este conducto. Se presenta el caso de un recién nacido en el que se constata salida de contenido intestinal através del ombligo. Se confirma el diagnóstico de persistencia del conducto onfalomesentérico mediante fistulografía umbilical, procediéndose a su corrección quirúrgica (resección de conducto onfalomesentérico). Se describe la metodología diagnóstica, su tratamiento y se revisa la bibliografía sobre esta patología.

Omphalomesenteric duct cyst as a content of omphalocele.

A rare occurrence of an omphalomesenteric duct cyst in an exomphalos minor sac is reported herein. The noteworthy points in this case were an unusual presentation of the rarest variety of umbilical cord cyst. The tapering intra-abdominal end of the cyst was found to be attached to the ileal mesentry, thereby simulating a herniating mesenteric cyst till the histolopathological report resolved the issue.

Spontaneous regression of patent omphalo-mesenteric duct.

We report a one-month-old male child with a patent omphalo-mesenteric duct that regressed spontaneously in the neonatal period and resulted in a Meckel's diverticulum.

Patent vitello-intestinal duct: an unusual presentation.

The case history of a child passing a roundworm through the umbilicus is presented. The diagnosis and management of a patent vitello-intestinal duct is discussed.
