Hernia of the umbilical cord associated with a patent omphalomesenteric duct.

Congenital hernia of the cord is a different type of ventral abdominal wall defect in which the bowel usually herniates into the base of normally inserted umbilical cord through a patent umbilical ring. It is rare congenital anomaly with incidence of 1 in 5000. Although it was described as a distinct entity since 1920s it is often misdiagnosed as a small omphalocele. We present an unusal case of term male newborn with umbilical cord hernia associated with patent omphalomesenteric duct. The diagnose was made after birth despite antenatal ultrasound scans and it is managed successfully with uneventful recovery. If this is missdiagnosed, it could cause iatrogenic atresia of the ileum by clamping the umbilical cord after birth.

Patent vitellointestinal duct with ileal prolapse in a newborn: A case report and literature review.

RATIONALE: Patent vitellointestinal duct is the most common omphalomesenteric duct anomaly to present with symptoms. PATIENT CONCERNS: A 10-day-old child presented with increase in the size of a polypoidal lesion into a large, "Y"-shaped reddish, prolapsing lesion, discharging gaseous, and fecal matter at her umbilicus. A laparoscopic exploration was performed, followed by wedge resection and anastomosis. No complications occurred during postoperative follow-up. DIAGNOSES: A patent vitellointestinal duct with ileal prolapse. INTERVENTIONS: The resection of extended intraperitoneal intestinal tube was performed. OUTCOMES: During the follow-up 3 months after surgery, the umbilical cord of the child healed well after surgery. LESSONS: Timely surgical treatment can minimize the occurrence of complications, and the overall prognosis is good after surgery.

Ileal prolapse through patent omphalomesenteric duct in a two year-old boy: a case report.

BACKGROUND: Patent omphalomesenteric duct is one of the birth defects included in the spectrum of vitelline duct abnormalities. It is a rare anomaly with estimated prevalence of 0.13-0.2% in the general population. The most common presentation of patent vitelline duct is yellowish or mucoid type umbilical discharge which is usually noted in neonatal age or infancy. The main stay of diagnosis is clinical and outcome is favorable as long as timely surgical correction is offered. Here we present a 2 years old male child who presented with ileal prolapse through patent vitelline duct which is an exceptional mode of presentation of this pathology. CASE PRESENTATION: 2 years old Ethiopian male child who was noticed to have umbilical discharge since early infancy presented with protrusion of pinkish mass per the umbilicus of 4 h duration. He had no signs and symptoms of bowel obstruction. Abdominal examination revealed a prolapsed bowel which was viable via the umbilicus which was about 6 cm long. Otherwise, he had no abdominal tenderness or rigidity. He was explored with a smiley incision just above the umbilicus. The prolapsed bowel was reduced gently to the abdominal cavity. The tract of the Patent vitelline duct was identified and completely resected along with a wedge of ileum at its base. Primary repair of the ileal end where the tract was inserted was done in two layers and abdomen was closed in layers. The child had smooth post op course and was discharged on the 4th post-operative day. CONCLUSION: Prolapse of a bowel through the umbilicus is unusual presentation of a rare anomaly namely patent vitelline duct. This presentation warrants early surgical intervention before bowel ischemia issues. Hence, all clinicians dealing with children should be aware of this rare pathology so that urgent surgical management can be offered.

Next Generation Sequencing in Vitellointestinal Duct Adenoma: Existence of Adenoma-Carcinoma Sequence or too Early to Predict?

Patent vitello-intestinal duct with adenoma is rare presentation. We report a case of a 1-month-old boy presenting with intermittent passage of stool and blood from the umbilicus since birth. On local examination polypoidal mass measuring 1×1 cm was seen protruding from umbilicus with faecal discharge. Ultrasound was performed which revealed a tubular hyperechoic structure, extending from umbilicus to part of small intestine measuring 30 ×30 mm and clinical diagnosis of patent vitello-intestinal duct was given, exploratory laparotomy, excision with umbilicoplasty done, and send for histopathological examination. On histopathological examination, patent vitello-intestinal duct adenoma was rendered and next generation sequencing (NGS) was performed revealing somatic mutation of KRAS (NM_033360.4; c.38G>A; p.Gly12Asp). To our knowledge, this is the first report of the adenoma in patent vitello-intestinal duct with NGS analysis. This case emphasizes the importance of thorough microscopic examination of resected patent vitello-intestinal duct and mutational analysis of the early lesions.

Intestinal prolapse through a persistent omphalomesenteric duct causing small-bowel obstruction.

Persistent omphalomesenteric duct as a cause of small-bowel obstruction is an exceptional finding. A neonate presented with occlusion due to intestinal prolapse through a persistent omphalomesenteric duct. Remnants of the duct were successfully resected, and the postoperative course was uneventful. We discuss the presentation of omphalomesenteric duct and its management.

Omphalomesenteric duct remnants: umbilical versus umbilical cord lesions.

The omphalomesenteric duct is an embryologic connection between the digestive tract and yolk sac, which typically involutes by the time of birth. Failure of the obliteration process can result in omphalomesenteric duct remnants. We present two cases of children with such remnants, one with an umbilical polyp requiring traditional excisional therapy and one more unusual case of an umbilical cord cyst resolving spontaneously without intervention. The differential diagnosis, which includes urachal remnants and umbilical pyogenic granulomas, is discussed, along with management and special considerations that practioners should be aware of when treating pediatric umbilical and umbilical cord lesions.

Postoperative ileo-ileal intussusception following surgical resection of patent omphalomesenteric duct.

A female neonate with patent omphalomesenteric duct was treated by ductal excision. Six days following surgery, she developed vomiting and abdominal distension. On plain radiographs, distended bowel loops with multiple, air-fluid levels consistent with an intestinal obstruction were evident. Sonography demonstrated an ileo-ileal intussusception. At surgery, a 3-cm, ileo-ileal intussusception was noted proximal to the previous Lembert suture site and was manually reduced. Awareness of the possibility of small-bowel intussusception following surgery was critical to ensuring prompt and successful treatment of this infant.

[A neonate with soft tissue protruding through the umbilicus]. / Een neonaat met weefsel uit de navel.

A 6-week-old neonate presented with soft tissue protruding through the umbilicus due to a persisting ductus omphalo-entericus. This remnant was surgically removed the next day.

Paediatric Postoperative Intussusception.

Intussusception is one of the common causes of acute abdomen in early childhood, particularly in children younger than two years of age. The majority of cases in children are idiopathic. Pathologic lead points can be identified in only 25 percent of cases. Here. we present a case of 15 months female child with Ileoileal postoperative intussusception with an anastomotic margin as a lead point, following resection anastomosis done for patent vitello intestinal duct. Role of high clinical suspicion, investigations and judgement are highlighted in managing the case. Keywords: Anastomosis; ileoileal; postoperative intussusception; patent vitello-intestinal duct.

Persistent omphalomesenteric duct causing small bowel obstruction in an adult.

An extremely rare case of persistent omphalomesenteric duct causing small bowel obstruction is presented. A 20-year-old female patient without medical history presented with colicky abdominal pain, vomiting, absence of passage of gas and feces, and abdominal distension of 24 h duration. Physical examination and blood tests were normal. Abdominal X-ray showed small bowel obstruction. Computed tomography of the abdomen demonstrated dilated small bowel and a band originating from the umbilicus and continuing between the small bowel loops; an omphalomesenteric duct remnant was suspected. In exploratory laparotomy, persistent omphalomesenteric duct causing small bowel obstruction was identified and resected. The patient had an uneventful recovery and was discharged on the 5(th) postoperative day. Although persistent omphalomesenteric duct is an extremely infrequent cause of small bowel obstruction in adult patients, it should be taken into consideration in patients without any previous surgical history.

Patent omphalomesenteric duct and exomphalos minor: a rare and interesting association.

A completely patent omphalomesenteric duct was seen in association with two cases of exomphalos minor. Both the patients also had limb anomalies, and one patient had an ileal duplication and colonic atresia. Both babies underwent emergency surgery to correct the anomalies, and one survived. There have been few reports of this combination of anomalies, and there is increasing appreciation that these lesions occur together more often than by chance.

Unusual Ileal Anomalies Associated with Omphalomesenteric Duct Remnants.

The association between omphalomesenteric duct remnants and other digestive tract malformations is not rare. Most associated anomalies are reported with Meckel's diverticulum. We report two associated anomalies which were never reported: an ileal stenosis and an ileal duplication. Surgeons must be aware of associated anomalies to prevent post-operative complications.

These umbilical lesions weren't granulomas after all.

Consider a VID remnant as part of the differential diagnosis for any patient who has what appears to be a granulomatous umbilical lesion. Order ultrasonography to evaluate a suspected VID, especially for lesions that fail to respond to 2 or 3 silver nitrate treatments. Surgical excision of a VID remnant is usually curative.

Vitelline duct anomalies. Experience with 217 childhood cases.

Of 217 children with vitelline duct anomalies, 85 (40%) had symptomatic lesions (mean age, 2.4 years). Forty-eight patients presented with rectal bleeding; 28, with intestinal obstruction; five, with abdominal pain; and four, with bilious umbilical drainage. An asymptomatic Meckel's diverticulum was discovered incidentally at laparotomy in 132 children. Surgical therapy included bowel resection in nine patients with volvulus, four with intussusception, seven with bleeding, three with vitelline cysts, and one with a perforation. Diverticulectomy was performed in 189 cases, and excision of a patent vitelline duct was accomplished in four neonates with umbilical drainage. Ectopic gastric mucosa was present in all 48 patients with bleeding and in four of five with inflammation but in only two asymptomatic specimens. More than one third of the cases were symptomatic and presented in younger patients. This suggests that elective resection of asymptomatic vitelline remnants in early childhood is reasonable at the time of laparotomy for other conditions.

Laparoscopic resection of patent omphalomesenteric duct in an adult.

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.

Laparoscopic management of incidentally noted omphalomesenteric duct remnant.

An adolescent undergoing laparoscopic varicocele ligation was incidentally found to have a persistent omphalomesenteric duct remnant. The fibrous band coursing between the umbilicus and terminal ileum was resected laparoscopically without difficulty. Remnants of the type presented herein should be removed to prevent subsequent complications.

Recognition and treatment of persistent omphalomesenteric ligament. A report of two cases.

Two patients undergoing diagnostic laparoscopy for chronic pelvic pain were discovered to have persistent omphalomesenteric ligaments. Excision was accomplished with Silastic banding and electrocauterization. These fibrous ligaments should be removed to relieve symptoms and to prevent other serious bowel complications.

Surgical treatment of patent omphalomesenteric duct presenting as faecal umbilical discharge.

A newborn infant with patent omphalomesenteric duct (POMD), who presented faecal umbilical discharge, was treated with a semicircular periumbilical incision up to the abdominal cavity. The omphalomesenteric duct was followed up to the junction with the small intestine and there resected. The abdominal wall was closed without resection of the umbilicus.

[The wet umbilicus: maybe not an umbilical granuloma?]. / De nattende navel: misschien geen navelgranuloom?

Three infants, 1 girl aged 10 months and 2 boys aged 2 and 4 months, presented with a discharging umbilicus directly or shortly after birth. Echography and cystography showed three different causes: a cystic remnant of the omphalomesenteric duct, a persistent urachus and a persistent omphalomesenteric duct. All were successfully managed surgically. The most common cause of a discharging umbilicus is an umbilical granuloma. This is usually treated by application of silver nitrate. In some patients, however, the discharge may not disappear or may contain urine or faecal material. These cases should be referred and echography performed. In case of an anomaly of the urachus or the omphalomesenteric duct, surgical exploration is mandatory. The lesion should be excised en bloc, together with a part of the bladder or the bowel.
