Childhood intussusception: Correlation between ultrasound reports and intra-operative findings

Abstract

Background: Intussusception, a common cause of intestinal obstruction in children, is usually diagnosed through ultrasound scan. The aim of this study was to evaluate the correlation between the ultrasound report and intra-operating findings in children who had laparotomy for intussusception. Materials and methods: This was a retrospective study of children aged 12 months and below who had laparotomy for intussusception between January 2017–December 2019 at the pediatric surgery unit of Enugu State University Teaching Hospital Enugu, Nigeria. Findings at ultrasound and findings at surgery were statistically compared. Results: A total of 103 cases of intussusceptions were seen during the study period. Out of this number, 69 patients were treated by laparotomy and formed the basis of this report. There was male predominance and the median age of the patients was 8 months. Abdominal pain was the most common presenting symptom. At presentation, about one-quarter of the patients were anemic while one-half of the patients had electrolyte derangement. Comparing the findings at ultrasound and findings at surgery, ultrasound was found to have an accuracy of 89.9%. Approximately, equal number of patients had manual reduction and bowel resection. Surgical site infection was the most common post-operative complication and mortality occurred in 8 (11.6%) patients. Conclusion: Ultrasound has high accuracy rate and is quite reliable for the diagnosis of intussusception.
