- CONCLUSIONS: Limited quality of the collected data, reporting bias.OMD is relatively rare; however the clinician must consider it while examining patients with umbilical abnormalities, since mismanagement could cause severe morbidity and mortality.

- CONCLUSIONS: Symptomatic VDP in the newborn demonstrates a significant gender difference. Symptomatic cases are more likely to have ectopic gastric tissue than non-symptomatic cases. Incidentally detected cases without removal should be followed closely for future complications.

The aim of this study was to examine the prevalence of embryologic remnants in umbilical cords of different gestational ages. Sections from 392 umbilical cords were examined using light microscopy. Of these, 52% contained at least 1 remnant, most commonly of the allantoic duct type. Although there was a significant decrease in vitelline duct remnants over increasing gestational age, from 11% at weeks 11-25 to 1.6% at weeks 36-42 (P = .009; χ2 test), the allantoic duct remnants remained constant in prevalence irrespective of gestational age.

Meckel's diverticulum represents a remnant of the proximal end of the omphalomesenteric duct, which constitutes a connection between the middle intestine and the vitelline vesicle. It is the most common congenital anomaly of the gastrointestinal tract and is found in approximately 0.3-2% of the general population. Complications such as hemorrhage, bowel obstruction, inflammation, perforation, intussusception, volvulus and malignant transformation develop in only 4-4.8% of all patients, with most cases presenting in childhood, while relative risk decreases during life. The aim of the present study is to present our experience in managing a 15-year old male patient with Meckel's diverticulum covered perforation. It was a case of disguised perforation of the Meckel's diverticulum, with development of adhesions to the anterior surface of the right third of the transverse colon, which was successfully treated on the basis of emergency. Diagnosis was made intraoperatively and was documented by histological examination of the excised diverticulum.

A total of 44 adult or juvenile nutrias were necropsied for disease survey. A large nodule was found in the liver of a nutria. The histopathological specimen of the hepatic nodule was microscopically examined, and sectional worms were found in the bile duct. The worms showed a tegument with spines, highly branches of vitelline glands and intestine. Finally, we histopathologically confirmed fascioliasis in a wild nutria. In the present study, a case of fascioliasis in a wild nutria is first confirmed in Korea.

The persistence of the embryonic vitelline duct can lead to omphalomesenteric duct anomalies. A wide variety of anomalies, depending on the remnant segment and its degree of involution, may occur as a result of the omphalomesenteric duct failing to obliterate completely. The most frequent omphalomesenteric duct anomaly is Meckel's diverticulum, which is present in approximately 2-3 % of the population. Despite the progress in medical imaging, conventional abdominal computed tomography and endoscopy have limitations for the diagnosis of Meckel's diverticulum. The laparoscopic exploratory remains the best choice for diagnosis and treatment.
- Vitelline fistula associated with omphalocele: Diagnostic dilemma? [Journal Article]
- IJInt J Surg Case Rep 2018; 47:45-47
- CONCLUSIONS: In our review of literature, VF associated with omphalocele had not been reported. Combination of anomaly maybe misleading, however, can be easily diagnosed the location of VF opening on the omphalocele sac, which is adjacent to the umbilical cord and luminal passage of meconium stool after birth. A fistulogram may be the best initial diagnostic imaging approach for identifying and confirmation of a fistula tract.VF associated with omphalocele is rare. Post-natal diagnosis is easily by gross appearance stoma like lesion, which is located just lateral of the umbilical cord, an intact omphalocele sac and post-natal meconium stool passage.

During embryonic development, most organs are in a state of mechanical compression because they grow in a confined and limited amount of space within the embryo's body; the early gut is an exception because it physiologically herniates out of the coelom. We demonstrate here that physiological hernia is caused by a tensile force transmitted by the vitelline duct on the early gut loop at its attachment point at the umbilicus. We quantify this tensile force and show that applying tension for 48 h induces stress-dependent elongational growth of the embryonic gut in culture, with an average 90% length increase (max: 200%), 65% volume increase (max: 160%), 50% dry mass increase (max: 100%), and 165% cell number increase (max: 300%); this mechanical cue is required for organ growth as guts not subject to tension do not grow. We demonstrate that growth results from increased cell proliferation when tension is applied. These results outline the essential role played by mechanical forces in shaping and driving the proliferation of embryonic organs.
