The urachus is a tubular structure that is apparent on the third week and connects the ventral cloaca to the yolk sac, as a progression from the allantois. Following the normal regression procedure, the urachus remains as the median umbilical ligament. Urachal remnants are present in 1.03% of paediatric patients while in 92.5% of cases represent incidental findings. Urachal anomalies are classified in four types as patent urachus (50-52%), urachal sinus (15%), urachal cyst (30%) and urachal diverticulum (3-5%). Ultrasound scan is the most commonly performed diagnostic imaging study. In case of symptomatic urachal remnants, surgical excision is indicated. Asymptomatic urachal remnants that are diagnosed at the neonatal period or early infancy should be watched up to 6 months of age, as they are likely to resolve. In persistent or symptomatic urachal remnants there is a risk of inflammation or even malignancy development, therefore we believe that there is indication for preventive surgical excision that may be performed either open or laparoscopically or by robot-assisted laparoscopy.

This is a case report about a patient presenting with a urachal mass mimicking a urachus adenocarcinoma. Cystoscopy showed a vesicourachal patent diverticulum. Histological findings after the removal of the umbilicus, urachus, urachal tumor, as well as a bladder cuff, consisted of a nonspecific polymorphous suppurative inflammatory infiltrate. Urachal adenocarcinoma is an aggressive tumor with poor prognosis if not treated while it is still localized. Surgical excision is the only recommended treatment that offers the best chances of survival. As no preoperative procedure has been proven accurate enough to rule out the diagnosis of adenocarcinoma, surgery appears to be inevitable.

Rare developmental anomalies known as urachal remnants are brought on by flaws in the foetal developmental process. However, depending on the location and degree of incomplete obliteration, the urachus can undergo a variety of urachal anomalies. An umbilical fistulogram and a voiding cystourethrogram both supported the existence of the adult urachal cyst in this case. To treat the sepsis, we provided the patient with antibiotics first, then a surgical procedure. The entire vesico-umbilical tract with the urachal cyst was removed using the open approach. The excised specimen's histology revealed a foreign body giant cell reaction without any indication of malignancy. The presentation and diagnosis of vesico-umbilical urinary fistula (VUUF) in adults can occasionally be difficult. They happen very rarely. So we began putting forward this case for the same reason.

A long diffuse giant umbilical cord (GUC), caused by umbilical cord edema associated with a patent urachus, is an extremely rare anomaly. While patients with diffuse GUC appear to experience no significant complications and a good prognosis, little is known about their etiology and prenatal course. Here, we report the first case of prenatally diagnosed diffuse GUC resulted from patent urachus in a monochorionic diamniotic twin with selective intrauterine growth restriction. This case indicates that GUC is epigenetic and unrelated to multiple births.

BACKGROUND
Abnormalities of the urachus include the patent urachus, cysts, sinus, and fistula. Each of these entities represents a failure of complete obliteration of the urachus. Contrary to other urachus anomalies, urachal cysts are usually small and silent unless they are infected. The diagnosis is often made during childhood. A benign noninfected urachal cyst discovered in adulthood is a rare condition.
CASE PRESENTATION
Herein we report two cases of benign noninfected urachal cysts in adults. The first case is a 26-year-old Tunisian white man who presented with complaints of clear fluid draining from the base of the umbilicus evolving for a week, with no other associated symptoms. The other case was 27-year-old Tunisian white woman who was referred to the surgery department with a history of intermittent draining of clear fluid from the umbilicus. The two cases had laparoscopic resection of urachus cysts.
DISCUSSION
Laparoscopy represents a good alternative for the management of persistent or infected urachus, especially when this is suspected, despite a lack of radiological evidence. Laparoscopy in the management of urachal cysts is safe, effective, and offers good cosmesis, with all the advantages of a minimally invasive approach.
CONCLUSION
Managing persistent and symptomatic urachal anomalies requires a wide surgical excision. Such intervention is recommended to prevent symptom recurrence and complications, most notably malignant degeneration. A laparoscopic approach offers excellent outcomes, and is recommended to treat these abnormalities.

Review
One of the typical complaints in the pediatric population is umbilical discharge. Among the congenital causes, remnants of omphalomesenteric duct or patent urachus are often detected. On a few occasions, multiple types of ectopic tissue are present. We describe histopathologic findings of two cases reported recently at our center as pediatric umbilical lesions with associated ectopic tissue. Histopathology of the excised mass confirmed the patent omphalomesenteric duct with ectopic gastric, duodenal, and colonic mucosa and pancreatic tissue in two patients with the clinical presentation of umbilical discharge. There were no associated congenital anomalies in these patients. The presence of multiple ectopic gastrointestinal mucosa and pancreas in the umbilical mass is unusual. Herein, we report these cases because of its rarity, multiple ectopic tissues, and reviewing the literature of the reported cases of multiple ectopic tissues.

Journal of Minimal Access Surgery 2023To report our experience in the laparoscopic management of symptomatic urachal remnants (URs) in adults.
AIM
To report our experience in the laparoscopic management of symptomatic urachal remnants (URs) in adults.
PATIENTS AND METHODS
A retrospective study included all patients who underwent laparoscopic excision of URs during the period January 2015-January 2020. The following data were retrieved from the files of the patients: demographic data, clinical presentations, intra-operative findings, the procedure performed, operative details, intraoperative or post-operative complications and follow-up period mentioned in the files for those patients.
RESULTS
The study included 10 patients (four males and six females) with a mean age of 27.8 ± 11.0 years. URs were discovered preoperatively in all patients except one patient who was diagnosed intraoperatively. URs were associated with other pathologies in four patients (40%) that required two simultaneous surgical procedures. Eight patients (80%) presented with simple umbilical discharge and were diagnosed easily by ultrasonography. All patients were managed successfully with laparoscopic excision and umbilical sparing technique. Excision of the dome of the bladder was done on the selective approach to one patient. No patients showed early post-operative complications. Only one patient had stitch sinus 6 months postoperatively due to a concomitant hernia repair rather than due to the excision of the URs.
CONCLUSIONS
Laparoscopic excision of symptomatic urachus is a feasible procedure even when the excision of the bladder is required. It could be performed successfully with other pathologies. It is associated with a low incidence of complications. Laparoscopy allows good visualisation and complete excision that leads to almost no recurrence rate.

Review
BACKGROUND
Giant umbilical cord, defined as a cord diameter of more than 5 cm, is an extremely rare malformation. There are few case reports of giant umbilical cord often associated with patent urachus duct or cystic malformation. These cases are usually managed by surgical excision and repair of patent urachus or cyst resection.
CASE PRESENTATION
We report the case of a 1-day-old Iranian boy with giant umbilical cord detected postnatally. The pregnancy course was uneventful, except for preterm premature rupture of the membrane and preterm delivery. There was no relevant family history. The patient was delivered by vaginal delivery with a good Apgar score. On clinical examination, the umbilical cord was very thick (about 6 cm in diameter), and huge fluctuating Wharton's jelly was observed. Other organs were normal. During the hospital stay, the patient did not develop any complications except borderline hyperbilirubinemia, which improved with conventional phototherapy. Since the umbilical cord had no discharge and was dried, the newborn was discharged with advice for cord drying care.
CONCLUSION
The newborn was well, and the dried umbilical stump was detached after 32 days, leaving a granulomatous structure without discharge. The patient was followed up for 4.5 months and had no problems except delayed separation of the umbilical cord.

Hepatic ciliated foregut remnants or cysts are congenital abnormalities resulting from retention of embryonic ciliated foregut within the liver. These structures are rarely reported in the human medical literature and have not been reported in the veterinary literature previously, to our knowledge. We describe here a case of an 8-wk-old male French Bulldog with a congenital patent hepatic ciliated foregut remnant resulting in an umbilicobiliary sinus tract. The dog also had concurrent gallbladder agenesis. The patient had yellow fluid discharging from the umbilicus, mimicking a patent urachus. Surgical exploration, removal, and histology provided a conclusive diagnosis of a hepatic foregut remnant and therapeutic resolution of the clinical signs. The histologic appearance of a hepatic foregut remnant is classical, namely a duct composed of 4 layers: an inner ciliated epithelial lining, loose connective tissue, smooth muscle, and a fibrous capsule.
