The Syringe Technique for Ultrasound-Guided Hydrostatic Intussusception Reduction

BACKGROUND: Ultrasound-guided hydrostatic reduction (UGHR) is a well accepted and widely used method of paediatric intussusception reduction, with the saline drip technique being the most commonly employed. AIMS AND OBJECTIVES: In this study we aimed to assess the outcomes of a novel technique of UGHR. MATERIALS AND METHODS: Data was obtained from a 15 year retrospective chart review of paediatric intussusceptions. Following resuscitation, UGHR was performed for uncomplicated intussusceptions using a 50cc syringe to infuse saline into the colon. It was performed in the ultrasound suite without sedation and time taken was monitored. A maximum of 3 attempts were done to achieve reduction. RESULTS: UGHR was attempted in 66 of 93 intussusceptions. The commonest type of intussusception was ileo-colic(91%) and the commonest symptom was vomiting(70%). Surgery was performed only when there was shock, peritonitis or repeated failed reductions. The median time taken for reduction was 4.9 minutes. The overall success rate was 83% with 89% of these requiring only a single attempt. There were no deaths or procedure related complications. CONCLUSIONS: The syringe technique for intussusception reduction is a safe, effective, and time-saving technique. Additionally, it offers the advantages of simplicity and rapidity of reduction and in experienced hands may not require pressure monitoring
