Retrograde jejunal-duodenal intussusception associated with a jejunal duplication cyst in a newborn

Retrograde Intussusception and Giant Meckel’s Diverticulum: An Uncommon Encounter

Retrograde intussusception (RINT) and giant Meckel’s diverticulum (MD) are both rare pathologies and are seldom encountered in surgical practice. Thus, it is exceptional for both conditions to be seen in the same patient, with very few published case reports in the paediatric population.

This case describes a three-month-old male who was referred to our paediatric surgery unit following a diagnosis of intussusception on an ultrasound scan. The patient presented to the paediatric emergency department one day prior with a clinical history of fever, cough, vomiting and irritability. After resuscitation, the patient was admitted for overnight observation in the paediatric ward. However, the patient’s symptoms persisted with notable abdominal distension. Abdominal X-ray (AP erect) showed features of small bowel obstruction, while abdominal ultrasound showed a concentric mass in the right upper quadrant consistent with intussusception. Following this diagnosis of intussusception, pneumatic enema reduction under ultrasound guidance was attempted but proved unsuccessful. The patient was then taken for emergency laparotomy. At surgery, an ileo-ileal RINT with a proximal giant MD was discovered. Successful manual reduction of the RINT and wedge resection of the giant MD with primary ileo-ileal anastomosis was performed. The postoperative recovery and follow-up were uneventful.

Giant Brunner's gland hamartoma causing retrograde jejuno-duodenal intussusception: A case report

Brunner's gland hamartoma is a rare benign duodenal tumor. It occurs in Brunner's glands, which are found in the duodenum and produce secretions that protect the duodenum from pancreatic enzymes, gastric acid, and other agents. Endoscopic or surgical resection is required for these hamartomas. Duodenal intussusception is a relatively rare condition, usually caused by the presence of benign tumors, such as fibroadenomas, lipomas, papillomas, or sometimes with malignant neoplasms.

We report a case of giant Brunner's gland hamartoma in the duodenum causing antiperistaltic intussusception in a 45-year-old female patient. The patient reported a 3-year history of chronic anemia, and this mass was detected incidentally by computed tomography (CT) during investigations for chronic anemia and weight loss. Pre-operative abdominal and pelvis contrast revealed a sausage-shaped intraluminal structure with alternating fat planes and vessels distended in the third part of the duodenum up to the first part of the duodenum. Pancreas-sparing duodenectomy was performed. The patient recovered very slowly and was discharged on postoperative day 15 in good condition. Histology showed a large polypoid mass measuring 12.0 × 7.5 × 2.0 cm³, consistent with Brunner's gland hamartoma.

Brunner's gland hamartoma can present with features of duodenal intussusception or ampullary obstruction but is rarely seen to cause retrograde jejuno-duodenal intussusception. Pancreas-sparing duodenectomy is the best surgical option in adult patients with intestinal intussusception associated with giant lesions close to the ampulla of Vater, especially in the presence of features of malignancy.

Jejunal duplication cyst displaying peristalsis and a five-layered appearance of the wall: a preoperative ultrasound diagnosis

A case of preoperatively diagnosed jejunal duplication cyst displaying the characteristic five-layered appearance of the gastrointestinal tract wall and peristaltic activity is reported. Both these rare features allowed a specific diagnosis of enteric duplication to be made.
