Strangulated small bowel obstruction in children

Infographic · Oct 2018 · 1 min read

In brief

Retrospective study of 69 pediatric SBO cases identifies clinical scoring system combining intractable pain, tachycardia, leukocytosis, and distention with imaging findings (ascites on US or wall thickening/reduced enhancement on CT) to predict intestinal strangulation. Clinical score ≥2 plus positive imaging shows strong predictive value for strangulation requiring urgent intervention.

Clinical score ≥2 (pain, tachycardia, WBC >13,600, distention) plus imaging findings predicts strangulation in pediatric SBO
Ascites on ultrasound or bowel wall thickening with reduced enhancement on CT are key imaging markers of strangulation
39% of pediatric SBO cases (27/69) had intestinal strangulation requiring prompt surgical intervention
Intractable continuous abdominal pain is a critical clinical indicator distinguishing strangulated from simple obstruction
Combined clinical scoring with targeted imaging improves preoperative identification of strangulation in children

The infographic uses a green banner to highlight four clinical predictors, with a stylized black intestine illustration on the left. Below, a flowchart in blue boxes shows the diagnostic algorithm: two or more predictors combined with either ascites or imaging findings indicate strong evidence for strangulation. The Journal of Pediatric Surgery logo appears in the top right corner.

Background

Diagnosing intestinal strangulation as a complication of small bowel obstruction (SBO) remains a considerable challenge in children. We evaluated the clinicoradiological parameters for predicting the presence of a strangulated intestine.

Methods

We reviewed the medical records of 69 pediatric patients who underwent operation for acute SBO. Regression analysis was used to identify the parameters for predicting strangulated SBO.

Results

Of the 69 patients with SBO, 27 patients had intestinal strangulation and were awarded one point each towards the overall clinical score: intractable continuous abdominal pain, tachycardia, white blood cell count >13,600/mm3, and abdominal distention. Patients with a clinical score ≥2 combined with the presence of ascites in ultrasound (US) results or with wall thickness and reduced wall contrast enhancement in abdominal computed tomography (CT) scans showed strong evidence for intestinal strangulation.

Conclusion

The combination of two or more clinical parameters, including intractable continuous abdominal pain, tachycardia, leukocytosis, and abdominal distention with the presence of ascites in US or wall thickness and reduced wall contrast enhancement in, is useful for the identification of strangulated SBO.
