Laparoscopic resection of antenataly identified duodenal duplication cyst

Abstract

We report the first case of complete laparoscopic resection of a duodenal duplication cyst (DDC) in an 8-mo-old patient. The cyst was diagnosed by routine antenatal ultrasound performed at 3 mo of gestational age. Although the baby was born asymptomatic without any congenital abnormalities, the cyst had continued to increase on serial sonographic examinations. Previous reports have described treatment of DDC by surgical resection (laparotomy) or endoscopic marsupialization; we describe here, the first report of laparoscopic approach to resect DDC in a pediatric patient with a favorable outcome.

Serial abdominal ultrasound examination revealed a RUQ cyst with an echogenic wall that demonstrated increase in size over 6 mo.

Figure 2.

Magnetic resonance imaging of abdomen revealed a 1.7cm x 1.2cm x 1.3cm fluid-containing structure with a uniform 3-mm wall (arrow) adjacent to the duodenal.

Computerized tomography (CT Scan) of the abdomen revealed a 1.9cm x 1.2cm diameter thin-walled cystic structure (arrow).
