title: Laparoscopic resection of patent omphalomesenteric duct in an adult.
abstract: The omphalomesenteric duct is the embryonic structure connecting the yolk sac to the primitive gut that disappears at 8 to 9 weeks of gestation. Failure of this duct to involute results in various anomalies. Failure of complete closure at different stages results in various anomalies, which occur in approximately 2% of the population. However, complete patency of omphalomesenteric duct is rare, reportedly occurring in approximately 15% omphalomesenteric duct anomalies. Adult presentations are extremely rare. We report the case of a 44-year-old man with a patent omphalomesenteric duct (POMD). He was admitted with a foul-smelling discharge from the umbilicus that he had experienced for 5 years. The condition had been interpreted as an umbilical granuloma at other centers, and multiple unsuccessful sessions of cauterization with silver-nitrate bar had been performed. At laparoscopy through three ports, the POMD was resected with the aid of a laparoscopic linear stapler. To our knowledge, this is the first adult case of POMD resected laparoscopically. The pitfalls of this diagnosis in the adult and the technique of laparoscopic resection is discussed in light of the available literature.
