Duplication cyst of the pylorus: a case report

Abstract

IntroductionPyloric duplication is an extremely rare gastrointestinal tract malformation in neonates. This is the first case report of pyloric duplication in our country (Lithuania).Case presentationWe report the case of a 2-day-old Lithuanian girl who suffered from pyloric duplication mimicking an alternative common bile duct cyst or other intra-abdominal organs cysts. A laparotomy was performed and the cystic formation of the pyloric area was successfully resected. The postoperative course was uneventful.ConclusionsThere are only a few reports describing abdominal masses caused by pyloric duplication mimicking common bile duct cyst or other intra-abdominal organs cysts. Therefore thorough clinical and instrumental examination is needed to determine the most accurate diagnosis that allows one to choose the right treatment.

Pyloric Duplication: About Two Cases

“…Only one third of the duplications is present in the neonatal period [19,20]. In literature, ages vary between 1 day and 2 years old [15,21]. Our patients are the oldest reported in case of pyloric duplication.…”

“…Nuclear scans using radioisotopes may show tracer uptake by ectopic gastric mucosa. Magnetic resonance imaging studies are useful in demonstrating the relationship with other structures [4,15]. If, after appropriate investigations, the diagnosis remains unclear, we suggest that laparoscopy should be used to confirm the diagnosis [22].…”

“…Some GID may be totally asymptomatic, identified on routine physical examination or during investigations for other problems. Common clinical manifestations of pyloric duplications include a palpable abdominal mass and non bilious vomiting which is almost present in all the cases of literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Bleeding, intussusception can be an occasion for discovering such unusual anomalies [3,20].…”

“…In most cases preoperative diagnosis is not made [2]. To our knowledge, no more than 20 cases of pyloric duplication have been reported in the English literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], most of them were extra luminal masses. Here in, we describe two cases with pyloric duplication cyst.…”

Enteric duplication in children: A case series

“…One of patients in our study also had pyloric ED (n = 1). [14,15] Enteric duplications may be cystic, tubular or mixed and they are located on mesenteric side of intestine. EDs may share its blood supply with adjacent intestine by residing in leaves of its mesentery, posing a difficulty for safe resection.…”
