OBJECTIVES: Early diagnosis and prompt surgical intervention are important to prevent intestinal necrosis in patients with volvulus. The purpose of this study was to determine which ultrasound (US) findings may predict bowel ischemic changes in pediatric patients with intestinal volvulus.
METHODS: Thirty-one pediatric patients with surgically proven intestinal volvulus were retrospectively reviewed. We compared the demographics and US findings (eg, superior mesenteric artery collapse, ascites, echogenic ascites, and degree of intestinal twist) between patients with and without bowel ischemic changes during surgery. Data are presented as median and range. The Fisher exact test, Mann-Whitney U test, and Wilcoxon signed rank sum test were used for statistical analyses.
RESULTS: Eleven patients had bowel ischemic changes. Significant differences existed between patients with and without ischemic changes for age (2 days [range, 0-137 days] versus 6.5 days [range, 2-1618 days]; P = .02), superior mesenteric artery collapse (present/absent, 10/1 versus 9/11 patients; P = .02), the presence of ascites (present/absent, 8/3 versus 6/14 patients; P = .03), and intestinal twist degree on US imaging (540° [range, 180°-720°] versus 360° [range, 180°-720°]; P = .02). The groups did not significantly differ for sex, the time from the US examination to the operation, or echogenic ascites. The intestinal twist degree insignificantly differed between US and surgical findings (360° [range, 180°-720°] versus 360° [range, 0°-1080°]; P = .36).
CONCLUSIONS: The presence of superior mesenteric artery collapse, ascites, and a large intestinal twist on US imaging were significant predictors of intestinal ischemic changes. Pediatric surgeons should perform prompt surgical interventions in cases of volvulus with these US findings.
