Pneumatic Reduction For Intussusception In Children: A Retrospective Cohort Study
An observational study of Intussusception, run by National Children's Hospital, Vietnam at 2 sites in Vietnam.
Trial summary
In pediatric patients, intussusception predominantly occurs in the ileocecal region, with over 90% of cases lacking identifiable causative factors, initiating through peristalsis-driven invagination of bowel segments leading to compromised blood flow and subsequent bowel edema.

Study population: Pediatric patients diagnosed with idiopathic intussusception admitted to the National Children's Hospital between January 2016 and December 2017
Who may be able to join
- All patients diagnosed with idiopathic intussusception, admitted to the National Children's Hospital between January 2016 and December 2017, exhibiting clinical signs and symptoms consistent with intussusception, and confirmed via ultrasound examination.
- Fluoroscopy-guided pneumatic reduction was performed with a maximum of three attempts. Patients who did not respond to pneumatic reduction underwent minimally invasive surgical intervention, either laparoscopic reduction or trans-umbilical mini-open reduction.
Who cannot join
- Patients demonstrating clinical instability characterized by signs of peritonitis or intestinal perforation necessitating conventional laparotomy.

About this study
Official title: Pneumatic Reduction For Intussusception In Children: A Retrospective Cohort Study In An Ultrahigh Volume Center
In pediatric patients, intussusception predominantly occurs in the ileocecal region, with over 90% of cases lacking identifiable causative factors, initiating through peristalsis-driven invagination of bowel segments leading to compromised blood flow and subsequent bowel edema. Persistent obstruction may progress to bowel ischemia and infarction. Vietnam exhibits a higher incidence of intussusception compared to other countries, albeit with similar clinical presentations and anatomical locations, hinting at shared pathophysiology. Despite evidence supporting the safety and efficacy of non-surgical reduction techniques, many medical centers in low- to middle-income countries (LMICs) have not adopted these methods, resulting in unnecessary surgical interventions. The Vietnam National Hospital of Pediatrics (NCH) has employed air enema reduction since the early 2000s but lacks a comprehensive study on fluoroscopic-guided air-enema reduction (FGAR) techniques or success rates. Thus, this study aims to evaluate the long-term outcomes of pneumatic reduction for intussusception at NCH, a high-volume institution in a lower-middle-income country.
Read the detailed description
In pediatric patients, intussusception primarily occurs in the ileocecal region, with more than 90% of cases lacking identifiable causative factors. The invagination of bowel segments is propelled by peristalsis, leading to compromised blood flow. This venous occlusion precipitates bowel edema, and if the obstruction persists, it can progress to bowel ischemia and infarction. The incidence of intussusception in Vietnam exceeds that of any other country with available data on incidence rates. Despite variations in incidence rates, intussusception's clinical presentation and anatomical location remain largely consistent between Vietnam and other countries, suggesting a common underlying pathophysiology. Many medical centers in low- to middle-income countries (LMICs) have yet to adopt these non-surgical approaches, resulting in unnecessary surgical interventions for a significant portion of patients. At the Vietnam National Hospital of Pediatrics (NCH), air enema reduction has been a standard practice since the early 2000s. Nonetheless, there has been no comprehensive study delineating the technique of fluoroscopic-guided air-enema reduction (FGAR) at NCH, nor assessing its success rate.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Fluoroscopic-guided air-enema reduction (FGAR)Procedure or surgery
A hand-held pump facilitated the delivery of atmospheric air, while pressure was monitored using a digital gauge. A two-way Foley's balloon catheter, ranging from 18oF to 24oF in diameter depending on age, was inserted rectally to introduce air. Following insertion, the balloon was filled with 10cc of saline to prevent air leakage, with patient immobilization ensured by leg straps and hand positioning above the head for abdominal exposure. Under intermittent fluoroscopy, the surgeon operated the pump with the right hand, inflating the catheter to 80 to 120 mmHg, simultaneously palpating the intussusceptum with the left hand, employing a deep gliding motion for deep and fixed cases. Successful reduction, indicated by air entry into the small bowel, was confirmed under fluoroscopy, with a subsequent brief rotating abdominal massage ensuring uniform air distribution throughout the small intestine, confirming complete reduction.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
In pediatric patients, intussusception predominantly occurs in the ileocecal region, with over 90% of cases lacking identifiable causative factors, initiating through peristalsis-driven invagination of bowel segments leading to compromised blood flow and subsequent bowel edema. Persistent obstruction may progress to bowel ischemia and infarction. Vietnam exhibits a higher incidence of intussusception compared to other countries, albeit with similar clinical presentations and anatomical locations, hinting at shared pathophysiology. Despite evidence supporting the safety and efficacy of non-surgical reduction techniques, many medical centers in low- to middle-income countries (LMICs) have not adopted these methods, resulting in unnecessary surgical interventions. The Vietnam National Hospital of Pediatrics (NCH) has employed air enema reduction since the early 2000s but lacks a comprehensive study on fluoroscopic-guided air-enema reduction (FGAR) techniques or success rates. Thus, this study aims to evaluate the long-term outcomes of pneumatic reduction for intussusception at NCH, a high-volume institution in a lower-middle-income country.

Questions about this trial
What is this clinical trial studying?
An observational study of Intussusception, run by National Children's Hospital, Vietnam at 2 sites in Vietnam.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Vietnam. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Complicated intussusception (time frame: through study completion (2 years)). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06365333, which also lists 20 linked publications.
Does a listing mean the treatment is approved or proven to work?
