Comparison of outcomes between complete and incomplete congenital duodenal obstruction

Table 2 Prenatal ultrasonographic detection rate and preoperative diagnostics for 50 patients with complete or incomplete congenital duodenal obstruction, and clinical presentations for 26 patients with prenatally unknown complete or incomplete congenital duodenal obstruction undergoing operative repair

	Complete	Incomplete	P value
	n = 27	n = 23
Fetal US screening, n (%)	261 (96)	23 (100)	1
Prenatally suspected by US (yes:no), n (%)	23 (88):3 (12)	1 (4):22 (96)	< 0.01a
Clinical presentation all prenatally unknown CDO	n = 42	n = 22
Vomiting, n (%)	4 (100)	20 (91)	1
Failure to thrive, n (%)		13 (59)
Intolerance of age-appropriate p.o. intake, n (%)		10 (45)
Constipation, n (%)	1 (25)	7 (32)	1
Postprandial discomfort/pain/restlessness, n (%)		5 (23)
ALTE (aspiration, apnea, bradycardia), n (%)		1 (5)
Intolerance to solid food, n (%)		1 (5)
Preoperative diagnostics	n = 27	n = 23
Plain abdominal X-ray, n (%)	27 (100)	1 (4)	< 0.01a
Upper GI contrast study, n (%)	0	23 (100)	< 0.01a
Gastroduodenoscopy, n (%)	0	4 (17)	0.04a

^aP < 0.05;

¹One maternity in the complete group was unsupervised (no prenatal ultrasound screening);

²n = 4 is sum of three prenatally unsuspected patients plus one patient without prenatal ultrasound. US: ultrasound; p.o.: Per oral; ALTE: Acute life-threatening event; GI: Gastrointestinal; CDO: Congenital duodenal obstruction.
