The omphalomesenteric or vitelline duct is an embryonic structure that communicates the yolk sac with the midgut, obliterating between 5-9 weeks of intrauterine life. Persistence of the omphalomesenteric duct, which can exist in up to 2% of population, is a congenital anomaly of the gastrointestinal tract that can present as abdominal pain, intestinal obstruction, or gastrointestinal bleeding.

Recognizing perforated Meckel's diverticulum: A crucial differential in acute appendicitis imitation.
Clin Case Rep
September 2024
The Medical Research Circle (MedReC) Goma Democratic Republic of Congo.
Article Synopsis
- Meckel's diverticulitis (MD) can mimic symptoms of acute appendicitis, specifically right lower abdominal pain, making it critical for clinicians to consider MD in such cases to prevent delays in diagnosis.
- The article presents a case of a 4-year-old girl who experienced sudden abdominal pain, ultimately leading to the discovery of a perforated MD during surgery, highlighting the need for vigilance in diagnosis.
- Timely advanced imaging and surgical intervention are crucial for accurately diagnosing MD and managing potential complications, as perforation can lead to serious health risks despite being uncommon.
Omphalomesenteric Ducts and Urachal Remnants: A Retrospective Study and Case Series.

Purpose: The management strategies for umbilical disorders remain undefined. This study aims to review our experience and propose a management algorithm for symptomatic urachal and omphalomesenteric duct anomalies.
Methods: We retrospectively reviewed medical charts between January 2013 and September 2017 of 28 patients with clinical concern for umbilical disorders, out of which 10 were diagnosed with omphalomesenteric duct remnants (OMDR) or urachal remnants (UR).

The venous pole of the heart where the pulmonary veins will develop encompasses the sinus venosus and the atrium. In the fourth week of development, the sinus venosus consists of a left and a right part receiving blood from the common cardinal vein, the omphalomesenteric and umbilical veins. Asymmetrical expansion of the common atrium corresponds with a rightward shift of the connection of the sinus to the atrium.

We present the case of a term newborn with trisomy 21 who presented to the paediatric emergency department with periumbilical flare and green-brown discharge from a clamped umbilical cord, initially suspected to be omphalitis. However, it was noticed later, that when the infant strained or cried, a thick, bubbling and offensive green-brown discharge came out of the clamped umbilical cord with umbilical flatus. An ultrasound abdomen and umbilical cord confirmed the presence of a persistent omphalomesenteric duct (POMD).

BACKGROUND Meckel's diverticulum is a congenital remnant of the omphalomesenteric duct and is the most common congenital gastrointestinal malformation. Most patients are asymptomatic, but a rare presentation is with subacute small bowel obstruction (SBO) due to herniation of bowel loops through an internal hernia formed by the Meckel's diverticulum and adjacent mesentery that forms an internal hernia. This report is of a 15-year-old girl presenting as an emergency with vomiting and small bowel obstruction due to an internal hernia associated with Meckel's diverticulum.
