Simple excision of umbilical polyp without peritoneal exploration in infants: a case series

Introduction Umbilical polyp is a rare form of vitelline duct remnant. Its optimal management remains controversial, particularly regarding the need for intraperitoneal exploration. Case Series Case 1 was a 5-month-old girl referred for a presumed umbilical granuloma. Ultrasonography showed a localized solid umbilical lesion without intraperitoneal communication, and ligation and excision were performed in an outpatient clinic. Histopathology confirmed an umbilical polyp with pyloric gland. Umbilical discharge resolved after excision, and she remained asymptomatic during follow-up. Case 2 was a 2-month-old girl with a suspected umbilical granuloma. Ultrasonography similarly showed no intraperitoneal continuity. Local excision was performed, and histopathology demonstrated fundic gland mucosa, ectopic pancreatic tissue, and intestinal epithelium, confirming the umbilical polyp. She remained asymptomatic during follow-up. Conclusion Umbilical polyps that have no intraperitoneal communication on ultrasonography seem to be amenable to a local excision in the outpatient setting without the need for an intraperitoneal exploration.
