Air enema for intussusception: is predicting the outcome important?

A POCUS-first pathway to streamline care for children with suspected ileocolic intussusception

OBJECTIVES

As point-of-care ultrasound (POCUS) has emerged as a valuable tool for intussusception screening, this quality improvement study aimed to implement a "POCUS-first" pathway in a Pediatric Emergency Department (ED) to streamline workflow and expedite care for children with suspected intussusception.

METHODS

This was a prospective analysis of children diagnosed with ileocolic intussusception in a Pediatric ED between June 2022 and June 2023. The study compared the "POCUS-first" cohort with the group receiving only radiology-performed ultrasound. Key outcomes included physician initial assessment to radiology-performed US time and physician initial assessment to reduction time. Continuous improvement efforts incorporated pediatric emergency medicine physician training, education, and pathway dissemination through plan-do-study-act cycles.

RESULTS

The study included 29 patients in the "POCUS-first" pathway group and 70 patients in the non-POCUS group. The "POCUS-first" pathway demonstrated a significantly shorter physician initial assessment to reduction time compared to the non-POCUS group (170.7 min vs. 240.6 min, p = 0.02). Among non-transferred patients, the "POCUS-first" group also had a significantly shorter emergency department length of stay (386 min vs. 544 min, p = 0.047).

CONCLUSIONS

Implementation of a "POCUS-first" pathway for managing ileocolic intussusception led to notable improvements in process efficiency. The shorter physician initial assessment to reduction time highlights the potential for expedited decision-making and intervention. These study findings support the potential of this pathway to optimize the management and outcomes of children with ileocolic intussusception.

Factors Associated with Failure of Pneumatic Reduction in Children with Ileocolic Intussusception

Intussusception is one of the most common causes of intestinal obstruction in children. Pneumatic reduction is the treatment of choice and has a high success rate. The most common cause of pneumatic reduction failure is the presence of a pathological leading point. We aimed to identify other factors that can lead to pneumatic reduction failure in children with ileocolic intussusception. This was a retrospective study conducted in two centers. Data were collected from January 2013 to December 2014. A total of 156 patients were diagnosed with intussusception and underwent pneumatic reduction, with the exception of one patient with peritonitis. We included patients with ileocolic-type intussusception without apparent pathological leading points. Logistic regression analysis of clinical parameters was performed to identify factors associated with pneumatic reduction failure. Of 156 patients diagnosed with intussusception in both hospitals, 145 were enrolled in the study. The overall efficacy of pneumatic reduction was 85.7%, and surgical reduction was performed in 21 patients. Univariate analysis showed that a high segmented neutrophil count, low hemoglobin level, high body temperature, and higher weight percentile were associated with pneumatic reduction failure. Multivariate analysis showed that a high segmented neutrophil count, low hemoglobin level, and higher weight percentile were significantly associated with pneumatic reduction failure. Pneumatic reduction is safe and effective as a first-line treatment for pediatric intussusception. However, a high segmented neutrophil count, low hemoglobin level, and higher weight percentile are associated with the failure of this treatment.

Practical Imaging Strategies for Intussusception in Children

OBJECTIVE. Intussusception is the most common cause of intestinal obstruction in young children. Radiology has a key role in its diagnosis and treatment. This systematic review summarizes the currently available evidence for best practices in radiologic management of pediatric intussusception. CONCLUSION. High diagnostic accuracy and lack of ionizing radiation make ultrasound (US) the preferred imaging modality for diagnosing intussusception. For intussusception reduction, fluoroscopy-guided pneumatic enema and US-guided hydrostatic enema are equally dependable and safe techniques. The areas that warrant further research in this field include the efficacy and safety of the US-guided pneumatic enema, potential benefits of sedation and general anesthesia for the reduction procedure, and the optimal management of intussusceptions potentially involving pathologic lead points.

Factors associated with ultrasound-guided water enema reduction for pediatric intussusception in resource-limited setting: potential predictive role of thrombocytosis and anemia

BACKGROUND/PURPOSE

Although ultrasound-guided hydrostatic reduction (USGHR) is increasingly used in managing pediatric intussusception, there is limited literature concerning its use in Malaysia. We aim to examine the experience and factors associated with the effectiveness of USGHR using water.

METHODS

This is a single-center retrospective observational study in a Malaysian tertiary referral center. Children with intussusception admitted between year 2012 and 2016 were included and medical records reviewed. Factors associated with success or failure of USGHR were identified using multivariable logistic regression.

RESULTS

Of the 172 cases included, 151 cases (87.8%) underwent USGHR, of whom 129 cases were successfully reduced (success rate of 85.4%). One perforation (0.7%) was reported. Age more than 3years old (aOR=7.16; 95% CI=1.07-47.94; p=0.042), anemia (aOR=10.12; 95% CI=1.12-91.35; p=0.039), thrombocytosis (aOR=11.21; 95% CI=2.06-64.33; p=0.005) and ultrasound findings of free fluid (aOR=9.39; 95% CI=1.62-54.38; p=0.012) and left-sided intussusception (aOR=8.18;95% CI=1.22-54.90, p=0.031) were independently associated with USGHR irreducibility. Symptom duration, blood in stool, vomiting and other clinical presentations, however, showed no association.

CONCLUSIONS

USGHR with water is effective in the non-operative management of pediatric intussusception. Prolonged symptom duration need not necessarily preclude USGHR. The findings of anemia and thrombocytosis as independent predictors of USGHR irreducibility deserve further study.

Prognostic indicators for failed nonsurgical reduction of intussusception

Purpose

To identify the risk factors for failure of nonsurgical reduction of intussusception.

Methods

Data from intussusception patients who were treated with nonsurgical reduction in Chiang Mai University Hospital and Siriraj Hospital between January 2006 and December 2012 were collected. Patients aged 0–15 years and without contraindications (peritonitis, abdominal X-ray signs of perforation, and/or hemodynamic instability) were included for nonsurgical reduction. The success and failure groups were divided according to the results of the reduction. Prognostic indicators for failed reduction were identified by using generalized linear model for exponential risk regression. The risk ratio (RR) was used to report each factor.

Results

One hundred and ninety cases of intussusception were enrolled. Twenty cases were excluded due to contraindications. A total of 170 cases of intussusception were included for the final analysis. The significant risk factors for reduction failure clustered by an age of 3 years were weight <12 kg (RR =1.48, P=0.004), symptom duration >3 days (RR =1.26, P<0.001), vomiting (RR =1.63, P<0.001), rectal bleeding (RR =1.50, P<0.001), abdominal distension (RR =1.60, P=0.003), temperature >37.8°C (RR =1.51, P<0.001), palpable abdominal mass (RR =1.26, P<0.001), location of mass (left over right side) (RR =1.48, P<0.001), poor prognostic signs on ultrasound scans (RR =1.35, P<0.001), and method of reduction (hydrostatic over pneumatic) (RR =1.34, P=0.023). The prediction ability of this model was 82.21% as assessed from the area under the receiver operating characteristic curve.

Conclusion

The identified prognostic factors for the nonsurgical reduction failure may help to predict the reduction outcome and provide information to the parents.

Intussusception patients older than 1 year tend to have early recurrence after pneumatic enema reduction

PURPOSE

To identify age risk factors of early recurrent intussusception after pneumatic enema reduction. Management opinions are proposed.

METHODS

Two thousand two hundred and ninety-five intussusception patients' medical records from January 2009 to December 2011 were retrospectively reviewed and analyzed.

RESULTS

Of the 2295 patients, the intussusception of 1917 of them was initially reduced by pneumatic enema, with 127 cases recurring within 72 h. The early recurrence rate is 6.62%. The early recurrence rate of patients younger than 1 year old is 2.1% (22/1032), while the rate for those older than 1 year is 11.9% (105/885). The difference is significant (P = 0.0001). There were no significant differences between age groups older than 1 year. One hundred and seventeen cases of recurrence happened within 48 h, which accounted for 92.1% of all early recurrence. Recurrence patients were treated again with pneumatic enema, with a successful reduction in 93.7%. They were followed up for 2-4 years; the long-term recurrent rate was 11.8% (14/119). No patient had poor prognosis because of delayed treatment.

CONCLUSION

Intussusception patients older than 1 year tend to have greater early recurrence rate after pneumatic enema reduction; 92.1% of the early recurrent cases happened in 48 h. There is no need to hospitalize patients after pneumatic enema reduction. A repeat pneumatic enema is a good choice before surgical approach.

Ultrasound-guided hydrostatic reduction of intussusception with saline: Safe and effective

PURPOSE

The study was undertaken to assess the efficacy of ultrasound-guided saline enema in reducing intussusception and to determine the role of age and duration of symptoms on this event.

METHODS

The case records of patients who were treated for intussusception at our institutions over the past 10 years were retrospectively analyzed. A total of 419 patients were treated for intussusception and 375 of them were included into the study. Patients were excluded if they had symptoms and signs of acute abdominal disease and required surgery as an initial treatment.

RESULTS

Hydrostatic reduction was successful in 313 of the 375 patients (83.46%). The procedure-related complication rate was nil. There were 29 episodes of recurrences in 23 patients, and recurrence rates did not differ between patients who responded to hydrostatic reduction and those who required surgery. Younger age [median (range); 11 months (3-108 months) vs. 20 months (1-180 months); p<0.05], rectal bleeding (p<0.01) and long duration of symptoms [mean (range); 1.95 days (1-7 days) vs. 1.44 days (1-10 days); p<0.01] were significantly associated with failed hydrostatic reduction.

CONCLUSION

Ultrasound-guided hydrostatic reduction is an easy, safe and effective method for the treatment of intussusception in the absence of acute abdominal findings.

Nonsurgical management of childhood intussusception: retrospective comparison between sonographic and fluoroscopic guidance

OBJECTIVES

The purpose of this study was to compare the effectiveness of sonography and fluoroscopy in guiding intussusception reduction and evaluate possible complications for each procedure.

METHODS

A retrospective analysis was performed by reviewing 31 cases of intussusception diagnosed and managed between January 2009 and January 2014 at the University of California, Davis Children's Hospital, after obtaining approval from the Institutional Review Board. To eliminate other confounding factors related to technique and experience, only cases performed by 2 pediatric radiologists who exclusively used either fluoroscopy or sonography were compared.

RESULTS

Fourteen patients (age range, 6-35 months) were treated by sonographic guidance using saline, and another 17 patients (age range, 2-57 months) were treated by fluoroscopy using either air or a water-soluble contrast agent. All 14 patients (100%) who underwent sonographically guided reduction were successfully treated without complications. Fourteen of the 17 patients (82%) who underwent fluoroscopic guidance had successful reductions. One complication of perforation was documented.

CONCLUSIONS

Sonography and fluoroscopy are equally effective in the nonsurgical management of childhood intussusception. The absence of ionizing radiation and better visualization of possible pathologic lead points makes sonography the ideal method.

Childhood intussusceptions at a tertiary care hospital in northwestern Tanzania: a diagnostic and therapeutic challenge in resource-limited setting

BACKGROUND

Intussusception remains a common cause of bowel obstruction in children and results in significant morbidity and mortality if not promptly treated. There is a paucity of prospective studies regarding childhood intussusception in Tanzania and particularly the study area. This study describes the pattern, clinical presentations and management outcomes of childhood intussusception in our setting and highlights the challenging problems in the management of this disease.

METHODS

This was a prospective descriptive study of patients aged < 10 years operated for intussusception at Bugando Medical Centre. Ethical approval to conduct the study was obtained from relevant authorities. Data was analyzed using SPSS version 17.0.

RESULTS

A total of 56 patients were studied. The male to female ratio was 3.3: 1. The median age was 6 months. Three-quarter of patients were < 1 year. Etiology was mainly idiopathic in 91.1% of cases. The classic triad of bloody stool, vomiting and abdominal distention/abdominal pain was found in 24 (42.5%) patients. The diagnosis of intussusception was mainly clinically in 71.4% of cases. All patients were treated surgically. Ileo-colic was the most frequent type of intussusception (67.9%). Twenty-six (46.4%) patients required bowel resection. The rate of bowel resection was significantly associated with late presentation > 24 hour (p = 0.001). Complication rate was 32.1% and surgical site infection (37.5%) was the most frequent complication. The median length of hospital stay was 7 days. Patients who had bowel resection and those who developed complications stayed longer in the hospital and this was statistically significant (p < 0.001). Mortality rate was 14.3%. Age < 1 year, delayed presentation, associated peritonitis, bowel resection and surgical site infection were the main predictors of mortality (p < 0.001). The follow up of patients was generally poor

CONCLUSION

Intussusception in our setting is characterized by late presentation, lack of specialized facilities and trained personnel for nonsurgical reduction. Therefore, surgery remains the main stay of treatment in our centre. A high index of suspicion and proper evaluation of patients is essential for an early diagnosis and timely definitive treatment, in order to decrease the morbidity and mortality associated with this disease.

Childhood intussusception: a literature review

Background

Postlicensure data has identified a causal link between rotavirus vaccines and intussusception in some settings. As rotavirus vaccines are introduced globally, monitoring intussusception will be crucial for ensuring safety of the vaccine programs.

Methods

To obtain updated information on background rates and clinical management of intussusception, we reviewed studies of intussusception in children <18 years of age published since 2002. We assessed the incidence of intussusception by month of life among children <1 year of age, seasonality, method of diagnosis, treatment, and case-fatality.

Findings

We identified 82 studies from North America, Asia, Europe, Oceania, Africa, Eastern Mediterranean, and Central & South America that reported a total of 44,454 intussusception events. The mean incidence of intussusception was 74 per 100,000 (range: 9–328) among children <1 year of age, with peak incidence among infants 5–7 months of age. No seasonal patterns were observed. A radiographic modality was used to diagnose intussusception in over 95% of the cases in all regions except Africa where clinical findings or surgery were used in 65% of the cases. Surgical rates were substantially higher in Africa (77%) and Central and South America (86%) compared to other regions (13–29%). Case-fatality also was higher in Africa (9%) compared to other regions (<1%). The primary limitation of this review relates to the heterogeneity in intussusception surveillance across different regions.

Conclusion

This review of the intussusception literature from the past decade provides pertinent information that should facilitate implementation of intussusception surveillance for monitoring the postlicensure safety of rotavirus vaccines.

Reduction of intussusception: defining a better index of successful non-operative treatment

The reported non-operative reduction rate for intussusception is usually the proportion of attempted non-operative (radiological) reductions that succeed, which we term the "selective reduction rate." This value shows wide variation that may result from selection bias that is difficult to quantify because data regarding primary operative treatment are frequently lacking. The proportion of patients with late clinical presentation or pathological lead points can also distort the apparent efficacy of non-operative treatment. We found no definitions of outcome measures in the literature or practice guidelines to inform analysis. Based on analysis of our own audit data we derived a "composite reduction rate" from first principles that can account for variations in radiological and surgical treatment thresholds that might bias other measures of successful non-operative treatment. This index is the proportion of intussusceptions not requiring resection that are successfully reduced non-operatively. We propose that the composite reduction rate be used as a key component of standardised multidisciplinary outcome reporting for intussusception rather than the selective reduction rate. The reduced bias and confounding would allow fairer comparisons and lead to better outcome standards.

Needle decompression to avoid tension pneumoperitoneum and hemodynamic compromise after pneumatic reduction of pediatric intussusception

BACKGROUND

The contemporary management of children with ileocolic intussusception often includes pneumatic reduction. While failure of the procedure or recurrence after reduction can result in the need for surgical treatment, more serious adverse sequelae can occur including perforation and, rarely, tension pneumoperitoneum. During the last year, four cases of perforation during attempted pneumatic reductions complicated by tense pneumoperitoneum have occurred in our center.

OBJECTIVE

We have elected to report our patient experience, describe methods of management and review available literature on this uncommon but serious complication.

MATERIALS AND METHODS

Using ICD-9 diagnosis codes, we reviewed the records of children with intussusception during 2011. Demographic and therapeutic clinical data were collected and summarized.

RESULTS

During the study period, 101 children with intussusception were treated at our institution, with 19% (19/101) of them requiring surgical intervention. Four children (4%) experienced a tense pneumoperitoneum during air enema reduction, prompting urgent needle decompression in the fluoroscopy suite. These children required bowel resection during subsequent laparotomy. No deaths occurred.

CONCLUSION

Pneumoperitoneum is a real and life-threatening complication of pneumatic enemas. It requires immediate intervention and definitive surgical management. Caution should be exercised by practitioners performing this procedure at institutions where pediatric radiology experience is limited and immediate pediatric surgical support is not available.

Risk factors for surgery in pediatric intussusception in the era of pneumatic reduction

INTRODUCTION

Surgical treatment is still necessary for intussusception management in a subgroup of patients, despite advances in enema reduction techniques. Early identification of these patients should improve outcomes.

METHODS

The medical records of patients treated for intussusception at our institution from 2006 to 2011 were reviewed. Univariate and multivariate analyses, including stepwise logistic regression, were performed.

RESULTS

Overall, 379 patients were treated for intussusception, and 101 (26%) patients required operative management, with 34 undergoing intestinal resection. The post-operative complication rate was 8%. On multivariate analysis, failure of initial reduction (OR 9.9,p=0.001 95% CI, 4.6-21.2), a lead point (OR 18.5,p=0.001 95% CI, 6.6-51.8) or free/interloop fluid (OR 3.3,p=0.001 95% CI, 1.6-6.7) or bowel wall thickening on ultrasound (OR 3.3,p=0.001 95% CI, 1.1-10.1), age <1 year at reduction (OR 2.7,p=0.004, 95% CI, 1.4-5.9), and abdominal symptoms>2 days (OR 2.9,p=0.003, 95% CI, 1.4-5.9) were significantly associated with a requirement for surgery. Similarly, a lead point (OR 14.5, p=0.005 95% CI, 2.3-90.9) or free/interloop fluid on ultrasound (OR 19.8, p=0.001 95% CI, 3.4-117) and fever (OR 7.2, p=0.023 95% CI, 1.1-46) were significantly associated with the need for intestinal resection.

CONCLUSION

Abdominal symptoms>2 days, age<1 year, multiple ultrasound findings, and failure of initial enema reduction are significant predictors of operative treatment for intussusception. Patients with these findings should be considered for early surgical consultation or transfer to a hospital with pediatric surgical capabilities.

Does the length of the history influence the outcome of pneumatic reduction of intussusception in children?

PURPOSE

Intussusception is the most common cause of acute abdomen in infants and preschool children. Nonoperative reduction using air enema is an established treatment in children with intussusception. The aim of this study was to determine whether length of the history influences the outcome of pneumatic reduction of intussusception in children?

METHODS

The medical records of 256 consecutive children with intussusception between July 1998 and June 2010, who underwent air enema reduction regardless of the length of the history were reviewed. In all 256 patients, intussusception was confirmed by ultrasound before proceeding to air enema.

RESULTS

The length of history ranged from 2 to 240 h with median time of 18.5 h. The median age in 256 patients was 7 months (range 1 day to 12 years). The presenting clinical features included irritability/abdominal pain (77%), vomiting (80%), bleeding per rectum (36%) and palpable abdominal mass (50%). Air enema reduction was successful in 234 (91.5%) of the 256 patients. In 22 (8.5%) patients, air enema failed to reduce the intussusception and 3 (1.1%) of these patients had colonic perforation during the procedure. All 22 patients required surgery. The duration of symptoms did not influence the outcome of pneumatic reduction. 37 (14%) patients developed recurrence after successful pneumatic reduction of intussusception, with 58% presenting within 48 h of the initial procedure.

CONCLUSION

Our data suggest that pneumatic reduction should be first-line treatment in all children with intussusception regardless of the length of the history.

Air encircling the intussusceptum on air enema for intussusception reduction: an indication for surgery?

OBJECTIVES

The prompt identification of children in whom enema reduction of intussusception might fail and surgery is necessary is crucial in order to avoid futile repeat attempts and untoward complications. The purpose of this retrospective review was to determine whether air encircling the intussusceptum in the small bowel during air enema for intussusception reduction could serve as an indication for operation rather than repeat attempts at radiological reduction.

METHODS

Imaging studies of 83 children aged 4 to 40 months with idiopathic intussusception who had air enema for intussusception reduction were reviewed for the presence of air encircling the intussusceptum in the distal small bowel. Findings were correlated with clinical course and surgical findings.

RESULTS

In 12 of 83 patients, air was seen encircling the intussusceptum in the small bowel, and in 11 of these (88%) air enema failed to reduce the intussusception. In 8 of the 11, delayed repeated attempts using air enema failed to reduce intussusception. Clinical signs and their duration did not differ between those children without and those with air encircling the intussusceptum.

CONCLUSION

In the presence of air encircling the intussusceptum in the distal small bowel on air enema, delayed repeated attempts for intussusception reduction are unlikely to succeed, and surgery is indicated.

Epidemiology of childhood intussusception and determinants of recurrence and operation: analysis of national health insurance data between 1998 and 2007 in Taiwan

BACKGROUND

To study the epidemiology of childhood intussusception and risk factors of recurrence and operation based on a nationwide data.

METHODS

Children with hospitalization due to intussusception (ICD9: 560.0) between 1998 and 2007 were identified from a national health insurance database. The incidence was calculated by age, sex, calendar year and month of admission. Recurrence and operation rates, duration and costs of hospitalization were analyzed.

RESULTS

A total of 8217 intussusception-related hospitalizations were identified in 7541 children. The incidence of intussusception peaked between 3 and 36 months of age. Male -to-female incidence rate ratio increased from 1.31 in the first year to 2.52 in the ninth year of life. The overall recurrence and operation rates were 7.9% and 24.9%, respectively. In children less than 1 year old, the recurrence rate was 10.1%, which decreased to 5.3% in children over 3 years old. Multiple logistic regression analysis showed that children receiving operation had a significantly lower risk of recurrence with an odds ratio (95% confidence interval) of 0.31 (0.24-0.41) after controlling for age and sex. There are significantly more cases occurring during the warmer months between May and October compared to the cooler months between November and April.

CONCLUSIONS

There was a male predominance of intussusception with a dynamic male-to-female incidence rate ratio. Children under 1 year of age have the highest recurrence and operation rates. Seasonal variation of intussusception was suspected in Taiwan.

Failure of enema reduction for ileocolic intussusception at a referring hospital does not preclude repeat attempts at a children's hospital

BACKGROUND

Some children with intussusception undergo attempted enema reduction at a hospital without pediatric radiology expertise and are transferred to a children's hospital (CH) if this is unsuccessful. We sought to determine whether a failed reduction (FR) at a referring hospital predicted failure of repeated attempts by a pediatric radiologist at a CH.

METHODS

A retrospective review of all children with ileocolic intussusception admitted to a large CH over 9 years was performed. Differences in outcome between those who initially presented to the CH and those who had a FR elsewhere before transfer (FR --> CH) were assessed.

RESULTS

A total of 152 subjects were identified. There was no difference in the frequency of successful enema reduction at the CH for those who initially presented at the CH (60.5%) and those who were transferred after a FR elsewhere (60.7%). The only predictor of successful reduction was anatomy, whereby 64% of intussusceptions proximal to the splenic flexure were reduced, but only 35% of those distal to that point (P < .01).

CONCLUSIONS

Children who are transferred to a CH after failed enema reduction elsewhere should undergo a repeat hydrostatic or pneumatic enema reduction in the absence of other contraindications.

Intussusception in infants younger than 3 months: a single center's experience

BACKGROUND

The diagnosis and treatment of intussusception is often confusing in infants aged younger than 3 months. This study aimed to discuss the particularity of diagnosis and treatment of intussusception in this age group.

METHODS

From April 1983 to June 2008, 39 infants aged 3 months or younger who had been diagnosed with intussusception were treated and their clinical data were analyzed retrospectively.

RESULTS

Of the 39 infants (29 boys and 10 girls), ages ranged from 12 hours to 3 months, with a mean age of 52.6 days. The duration from onset to admission ranged from 7 to 142 hours (mean 39.6 hours). Three infants had intrauterine intussusception and 36 postnatal intussusception. The 3 infants with intrauterine intussusception had typical presentations of complete ileus after birth. Gap type ileal atresia was found in surgery in 2 of the 3 infants and primary anatomosis was performed therapeutically. The other infant was found to have ileal separation and a patent proximal end with diffused meconium peritonitis. The patient died 2 days after primary anastomosis. Most infants with postnatal intussusception had two or more manifestations of the tetralogy, namely intermittent screaming, vomiting, bloody stool, and abdominal mass. In 23 infants who underwent pneumatic reduction, 17 had a successful reduction and 6 converted to open surgery. Surgery was indicated for 19 infants, with maneuver procedure in 14. Meckel's diverticulum was noted as a leading cause in 2 infants, ileal duplication in 1 with necrosis of intussusceptum, and primary intussusception with lead point necrosis in 2. The 5 infants, on whom segmental resection was performed, underwent primary anastomosis. All infants with postnatal intussusception had a smooth recovery.

CONCLUSIONS

Infants aged 3 months or younger may suffer from intussusception and most of them present with typical symptoms. Early diagnosis and treatment are needed for a good prognosis. Intrauterine intussusception may be an etiological factor for ileal atresia.
