Bilious vomiting is a relevant sign in children that requires immediate evaluation and diagnosis. One of the causes is an obstruction of the intestinal tract due to duplication if located distal to the major duodenal papilla of Vater. Most of the duplications involve the jejunum, stomach, and colon. Duodenal duplications are very rare and can have an endoscopic or surgical treatment after diagnosis. We are reporting here a case of duodenal duplication in a 3-month-old male child who presented to us with bilious vomiting. Most of them are associated with other anomalies. Completely isolated duodenal duplication is very rare. Therefore, we tried to review the topic while presenting this rare case report of isolated duodenal duplication cyst.

| Introduction|| |
Duplications of the alimentary tract are rare developmental abnormalities. They can be observed anywhere along the alimentary tract, and they are located most often in the ileum and least often in the duodenum. Duodenal duplication constitutes 5%–7% of all gastrointestinal duplications. The clinical features of the duodenal duplication may vary from asymptomatic to symptoms such as abdominal pain, abdominal distension, and vomiting. Patients may develop symptoms of gastric outlet obstruction or small bowel obstruction. Ulceration or perforation due to the presence of an ectopic mucosa may cause duodenal bleeding or peritonitis, respectively. It may present as recurrent pancreatitis due to direct pressure over the pancreatic duct, stone formation in cyst due to stasis, jaundice and intussusception, and hemorrhagic ascites. We are presenting here a case of huge duodenal duplication in a 3-month-old male child, presented to us with the complaint of bilious vomiting with a palpable lump abdomen.
| Case Report|| |
Parents of a 3-month-old male child presented to us with complaints of bilious vomiting with palpable lump abdomen for the past 5 days. There was also history of the intermittent episodes of nonbilious vomiting which were relieved by medications locally. On examination, the abdomen was soft with palpable lump in the right hypochondrium. Routine blood investigations were within normal limits. Ultrasound abdomen revealed a 52 mm × 33 mm size double-layered anechoic cystic lesion with echoes adjacent to the second part of the duodenum, causing compression on the duodenum. Contrast-enhanced computed tomography (CECT) abdomen revealed a well-defined cystic hypodense lesion (42 × 35 × 47) noted abutting the second part of the duodenum and anterior part of the right kidney [Figure 1]. It was causing the compression of the second part of the duodenum with mild distension of the duodenum. Both ultrasound sonography abdomen and CECT abdomen were suggestive isolated duodenal duplication cyst in the second part of the duodenum on the mesenteric border. The lumen did not connect with the duodenum. We explored the patient; huge duodenal duplication was present in the second part of the duodenum [Figure 2]. Due to proximity with the other structure, partial excision with internal deviation was done. The patient was discharged uneventfully after 7 days. Histopathology report showed duodenal duplication with the ectopic gastric mucosa [Figure 3].
| Discussion|| |
Gastrointestinal tract duplication is a congenital abnormality. It has well-developed smooth muscle lining. The epithelial lining represents some portion of the alimentary tract. It has equal incidences among males and females. They may be single or multiple and usually found along the first and second portions of the duodenum on its mesenteric side on the anterior wall. The blood supply is usually associated with that of the duodenum so that surgical dissection of the duplication from the duodenum is often impossible. Communication with the main lumen is rare. Communication with the pancreaticobiliary ductal system has also been reported.
They are lined by mucosa, usually similar to that of the duodenum, but ectopic gastric (15%), small intestinal, and pancreatic mucosae have has also been reported. Outer lining is one or more layer of smooth muscle. Peristaltic movements may be present. Contents may be mucilaginous, mucoid or watery, and clear or reddish brown in color. It can be associated with other congenital anomalies such as double gallbladder, congenital dislocation of the hip, ventricular septal defect, patent ductus arteriosus, ileal and gastric duplications, and mediastinal and esophageal cysts, while in our case, it was isolated duodenal duplication.
Duodenal duplication can be cystic or tubular, communicating or noncommunicating, but the most common type is cystic and noncommunicating. In our case, it was cystic, noncommunicating, and located in the second part of the duodenum. It is usually diagnosed in infancy and childhood. However, many patients can remain asymptomatic until adulthood.
The preoperative diagnosis of intestinal duplications is rarely accurate. In barium studies, in noncommunicating cysts, the first and the second parts of the duodenum can be seen as compressed and displaced by a mass, whereas in the communicating type, the cyst itself can be observed as being filled with barium. Duodenal duplication is differentiated from other cystic lesions by the “gut signature” of its wall observed by abdominal or endoscopic ultrasound. Gut signature refers to the layered pattern of the wall, with the hyperechoic inner layer representing the submucosa and the hypoechoic outer layer representing the smooth muscle. Peristalsis of the cyst wall noted on real-time ultrasound is strongly suggestive of a duplication cyst. CT is valuable in identifying the type, location, and size of the duplication cyst. Magnetic resonance imaging and gastroduodenoscopy are the other modalities that can be used for diagnosis.
In spite of the diagnostic workup performed before the operation, accurate diagnosis of duodenal duplication is by histological examination. According to the analysis made by Uzun et al., two types of intra- or juxta-duodenal duplications occur: (1) a common wall formed by two separate mucosae with their own muscularis mucosa and a layer of intervening connective tissue and (2) a common wall that comprises two mucosal layers with two smooth muscle layers but that also contains biliary and pancreatic ducts.
Prenatal diagnosis has been reported from 20 weeks of pregnancy, allowing the medical team to plan in advance an early postnatal treatment. The isolated cyst can be managed conservatively. Surgical management is required based on symptoms and complications (obstruction or bleeding).
If the distal biliary and pancreatic ducts are not traveling through the common wall between the duplication cyst and duodenum, endoscopic treatment with duodenocystostomy is favored as a less invasive procedure. If located in the common wall, then laparotomy or laparoscopic exploration is recommended, and the technique includes duodenotomy and then duodenocystostomy or fenestration of the cyst.
Total excision is an optimal approach. However, if the lesion occurs closed to the pancreaticobiliary tract, performing the total excision is difficult and risky, and then, partial resection or internal derivation must be carried out. In partial resection, the entire cyst wall is removed wherever possible while the area of maximum adherence to the duodenum is preserved.,, Recently, endoscopic fenestration has been reported. Duodenal duplication has the possibility to become malignant. In some cases, carcinoid tumor was found in the wall of the duplication cyst. it can be treated endoscopically, but it relieve only symptoms without excising the lesion. in future there is chance to turn in malignancy. Therefore, we treated our patient with subtotal excision and internal derivation, which cured the patient.
Histologically, duodenal cysts have all layers of the intestinal wall, but in few cases, they can present ectopic gastric and pancreatic mucosa, which might be related to local bleeding before or after the surgical treatment. Complete resection of the cyst or mucosal stripping are indicated because of the possibility of the malignancy from the ectopic tissues and chronic inflammation of the mucosa.,,, We also did mucosal stripping.
Nowadays, after diagnosis and if surgery is indicated, laparoscopic treatment should be considered in the first place with the possibility of resection or duodenocystostomy and mucosal stripping if technically possible, though the chances of future malignancies are noted in one report only. Resection of the duodenal segment and Roux-en-Y anastomosis should be reserved for cases in which there was an extremely distorted anatomy, and biliary ducts were injured during endoscopic or surgical treatment.
| Conclusion|| |
Duodenal duplication should be considered in the differential diagnosis of a patient who presents with vomiting and abdominal symptoms, especially when cystic structures neighboring the duodenum are demonstrated radiologically. Ideal treatment is total excision but, if not possible, subtotal excision and/or internal derivation should be performed. When treated properly, these lesions usually have favorable outcomes.
