THE UMBILICAL POLYP, A REMNANT OF THE OMPHALOMESENTERIC DUCT

THE PURPOSE of this paper is to report a recent case of an umbilical polyp and intestinal obstruction during the neonatal period. Umbilical polyps are rare. When present, they may be associated with Meckel's diverticulum because both are remnants of the omphalomesenteric duct. The presence of the visible polyp may give an external clue to otherwise obscure intraabdominal symptoms. A review of the literature earlier than 1916 is well summarized in a book by Thomas Cullen. This unusual volume lists six cases of umbilical polyp accompanied by other pathologic complications of Meckel's diverticulum. This author stressed that in these cases it should be pointed out to either the patient or his parents that possible intra-abdominal duct remnants may, at any time, give rise to symptoms such as intestinal obstruction. Penberthy and Benson reported a 9-year-old male with an umbilical polyp which had been present since birth and was without discharge. This youngster died following operation for intestinal obstruction due to volvulus about the diverticulum and its fibrous connection with the umbilical polyp. These authors pleaded for early elective operations in these cases prior to such complications. Gross gave other reasons for observation, and exploration at a reasonably early age, if a Meckel's diverticulum is suspected. Peritonitis from a ruptured Meckel's diverticulum is peculiarly dangerous; in young children the protecting omentum is inadequate and the migrating nature of the anomaly adds to the danger. Fluid from perforation of a diverticulum is usually of greater volume than that found in appendiceal rupture and abscess.
