Abstract
Gastrointestinal duplication cyst is a rare congenital anomaly that may occur anywhere along the gastrointestinal tract from the tongue to the anus. Such cysts occur most commonly in the small bowel and about half are in the mesenteric border of the ileum. Such cystic duplications communicate only rarely with the intestinal lumen although the cysts are attached to the intestine and may even share a common wall with the adjacent alimentary tract. These lesions can vary in shape, being cystic or tubular, and often show the same structure of the adjacent normal bowel. It is usually asymptomatic and complications are rare but they may include obstruction by volvulus or intussusception, bleeding, infection, and perforation. When diagnosed these lesions should be surgically resected to avoid future possible complications. The authors present a case of enteric cystic duplication and its ultrasound appearance in a 12-month-old Caucasian female infant cause of acute abdominal pain and intestinal obstruction, thus requiring urgent surgery.
Riassunto
La duplicazione digestiva è una rara anomalia congenita che può essere localizzata in ogni tratto del canale digestivo, dalla base della lingua all’ano. Si riconoscono più comunemente nel piccolo intestino e circa la metà sono a localizzazione ileale. Comunicano solo raramente con il lume intestinale spesso stabilendo intimo contatto con il canale alimentare adiacente con condivisione di parete. Può mostrare forma cistica o tubolare e tipicamente mostra la stessa struttura delle viscere normale adiacente. Di solito è asintomatica e le complicanze sono rare ma possono includere occlusione da volvolo o da invaginazione, emorragie, infezioni, e perforazione. Quando diagnosticata, questa lesione deve essere asportata chirurgicamente per evitare in futuro possibili complicazioni. Gli Autori presentano un caso di duplicazione di tipo cistico dell’ileo terminale e le sue caratteristiche ecografiche osservate in una infante di 12 mesi giunta alla nostra attenzione con dolore addominale acuto ed occlusione intestinale, che ha richiesto successivo intervento chirurgico in regime di urgenza.
