Prenatal ultrasonic diagnosis of congenital duplication of the stomach.

Abstract

A case of gastric duplication cyst first visualized sonographically in the prenatal period is described. The prenatal identification of abnormality allowed prompt postdelivery diagnosis and surgical treatment. The characteristic location of this cyst is in the right upper quadrant of the fetal abdomen. The presence of peristalitic activity within the cyst can point to a gastrointestinal origin. A hypoechoic outer rim and hyperechoic inner rim also suggests the stomach as the etiologic origin of the cyst. With this entity, the presence of associated congenital anomalies should be sought. No known associated genetic chromosomal anomalies are reported.

Management of alimentary tract duplication in children

“…Twenty-four (40 per cent) presented by 1 month of age and 40 (67 per cent) by 1 year. Associated anomalies, excluding Paper accepted 16 May 1994 74 vertebral defects, were recorded in 29 patients (48 per centi the commonest of these was midgut malrotation, which was identified in 12. In five patients (8 per cent), each with a different duplication site (thoracoabdominal, gastric, jejunal, ileal, caecal), the cyst had perforated before operation; this was secondary to peptic ulceration in three.…”

Prenatal diagnosis of an intrathoracic gastric duplication: a case report

“…Prenatal detection of gastric duplication allows appropriate management and approach at birth. As far as we know, all previously detected gastric duplications were located in the abdomen [6][7][8][9]. We report what we believe is the first case of an isolated intrathoracic gastric duplication detected on a routine prenatal ultrasound examination.…”

Prenatal diagnosis of abdominal enteric duplications

“…This may be related to the fetal ultrasonic features of the stomach, which enables easier detection of a neighbouring cyst. Following the prenatal appearance of an abdominal cyst, alimentary tract duplication was suspected only in the case reported by Bidwell and Nelson (1986) as well as in ours. In the other cases, the presumed prenatal diagnoses were: a gastrointestinal tract obstruction (van Dam, 1984;Bale Ân et al, 1993); a biliary tract abnormality (Goyert et al, 1991); a cystic neuroblastoma (Duncan et al, 1992;Richards et al, 1996); a renal cyst (Degani et al, 1995;Richards et al, 1996); and a gastric teratoma (Richards et al, 1996).…”

“…The prenatal diagnosis of an enteric duplication allows for planning of the appropriate postnatal workup in order to establish the diagnosis and to screen for associated malformations. Although performed only in our case, the detection of ectopic gastric mucosa by radioisotope scanning with 99m Tc-pertechnate could be helpful in postnatal work-up to con®rm the diagnosis, particularly as histological examination revealed ectopic gastric mucosa on at least 60% of antenatally detected enteric duplications (Bidwell and Nelson, 1986;Brink and Balsara, 1991;Goyert et al, 1991;Bale Ân et al, 1993, Degani et al, 1995, Richards et al, 1996, Ilari et al, 1998. Furthermore, antenatal detection allowed prompt surgical treatment and avoided complications.…”
