The objective of the work was to analyze the diagnostic accuracy of transabdominal ultrasound in diseases causing hematochezia. The present retrospective study included 427 pediatric patients with hematochezia or hematochezia accompanied by abdominal pain, who came to our hospital from October 2014 to September 2018. Transabdominal ultrasound was performed in all patients. Demographic data such as age, gender and clinical variables including symptoms and the hematochezia aspect were recorded. The diagnostic accuracy was analyzed. Among all patients, the hematochezia types were dark red bloody stools 163 (38.2%), black stools 102 (23.9%), jam-like bloody stools74 (17.3%), scarlet blood 55 (12.9%) and fecal occult blood 33 (7.7%). There were 153 (35.8%) patients with intussusception, 116 (27.2%) patients with Meckel’s diverticulum, 95 (22.2%) patients with intestinal duplication, and 63 (14.8%) patients with intestinal polyps. Transabdominal ultrasound showed there were 150 patients with intussusception, with an accuracy of 98.0%; 103 patients with Meckel’s diverticulum, with an accuracy of 88.8%; 84 patients with intestinal duplication, with an accuracy of 88.4%; and 54 patients with intestinal polyps, with an accuracy of 85.7%. The diagnostic sensitivity was significantly higher for intussusception than for other diseases. It is concluded that transabdominal ultrasound had a high accuracy in the diagnosis of hematochezia-related diseases, including intussusception, Meckel’s diverticulum, intestinal polyps and intestinal duplication.
