Factors associated with in-hospital recurrence of intestinal intussusception in children.

BACKGROUND: A minority of children experience in-hospital recurrence of intestinal intussusception after treatment. This study investigated the factors associated with in-hospital recurrence of intussusception in pediatric patients in China. METHODS: This retrospective study included patients aged 0-18 years-old with intestinal intussusception treated at Hainan Women and Children's Medical Center between January 2019 and December 2019. Demographic and clinical characteristics were extracted from the medical records. Factors associated with in-hospital recurrence of intussusception were identified by logistic regression analysis. RESULTS: The analysis included 624 children (400 boys) with a median age of 1.8 years (range, 2 months and 6 days to 9 years). Seventy-three children (11.7%) had in-hospital recurrence of intussusception after successful reduction with air enema. Multivariate logistic regression analysis identified age > 1 year-old (odds ratio [OR]: 7.65; 95% confidence interval [95%CI]: 2.70-21.71; P < 0.001), secondary intestinal intussusception (OR: 14.40; 95%CI: 4.31-48.14; P < 0.001) and mesenteric lymph node enlargement (OR: 1.90; 95%CI: 1.13-3.18; P = 0.015) as factors independently associated with in-hospital recurrence of intussusception. CONCLUSIONS: Age > 1 year-old, secondary intussusception and mesenteric lymph node enlargement were independently associated with increased odds of in-hospital recurrence of intussusception after successful reduction with air enema.

[Reduction of ileocolic intussusception with hydrostatic enema under ultrasound guidance in pediatric patients: Case report]. / Reducción de intususcepción ileocólica con enema hidrostático bajo guía ecográfica en pacientes pediátricos: Reporte de casos.

Ileocolic intussusception is a pediatric emergency with initial non-surgical treatment. Ultrasound-guided hydrostatic reduction in pediatric patients is a widely used initial treatment method in the world; however, its use is not widespread in our environment. We present 4 cases of patients with ileocolic intussusception treated by ultrasound-guided hydrostatic reduction in the Instituto Nacional de Salud del Niño - San Borja (INSNSB), with therapeutic reduction and without complications.

Sedation and Analgesia for Reduction of Pediatric Ileocolic Intussusception.

Importance: Ileocolic intussusception is an important cause of intestinal obstruction in children. Reduction of ileocolic intussusception using air or fluid enema is the standard of care. This likely distressing procedure is usually performed without sedation or analgesia, but practice variation exists. Objective: To characterize the prevalence of opioid analgesia and sedation and assess their association with intestinal perforation and failed reduction. Design, Setting, and Participants: This cross-sectional study reviewed medical records of children aged 4 to 48 months with attempted reduction of ileocolic intussusception at 86 pediatric tertiary care institutions in 14 countries from January 2017 to December 2019. Of 3555 eligible medical records, 352 were excluded, and 3203 medical records were eligible. Data were analyzed in August 2022. Exposures: Reduction of ileocolic intussusception. Main outcomes and measures: The primary outcomes were opioid analgesia within 120 minutes of reduction based on the therapeutic window of IV morphine and sedation immediately before reduction of intussusception. Results: We included 3203 patients (median [IQR] age, 17 [9-27] months; 2054 of 3203 [64.1%] males). Opioid use was documented in 395 of 3134 patients (12.6%), sedation 334 of 3161 patients (10.6%), and opioids plus sedation in 178 of 3134 patients (5.7%). Perforation was uncommon and occurred in 13 of 3203 patients (0.4%). In the unadjusted analysis, opioids plus sedation (odds ratio [OR], 5.92; 95% CI, 1.28-27.42; P = .02) and a greater number of reduction attempts (OR, 1.48; 95% CI, 1.03-2.11; P = .03) were significantly associated with perforation. In the adjusted analysis, neither of these covariates remained significant. Reductions were successful in 2700 of 3184 attempts (84.8%). In the unadjusted analysis, younger age, no pain assessment at triage, opioids, longer duration of symptoms, hydrostatic enema, and gastrointestinal anomaly were significantly associated with failed reduction. In the adjusted analysis, only younger age (OR, 1.05 per month; 95% CI, 1.03-1.06 per month; P < .001), shorter duration of symptoms (OR, 0.96 per hour; 95% CI, 0.94-0.99 per hour; P = .002), and gastrointestinal anomaly (OR, 6.50; 95% CI, 2.04-20.64; P = .002) remained significant. Conclusions and Relevance: This cross-sectional study of pediatric ileocolic intussusception found that more than two-thirds of patients received neither analgesia nor sedation. Neither was associated with intestinal perforation or failed reduction, challenging the widespread practice of withholding analgesia and sedation for reduction of ileocolic intussusception in children.

Methicillin-resistant Staphylococcus aureus enterocolitis in a 16-month-old boy: a case report.

BACKGROUND: Methicillin-resistant Staphylococcus aureus enterocolitis is a rare disease that typically affects immunocompromised adults. Most cases of pediatric enterocolitis are caused by Gram-negative bacteria, Gram-positive Clostridiodes difficile, or viruses. This is the first published case report of a toddler with methicillin-resistant Staphylococcus aureus enterocolitis. CASE PRESENTATION: A 16-month-old non-Hispanic White boy with no past medical or psychosocial history initially presented to the emergency room with abdominal pain and emesis. Past family history was pertinent only for his father having a history of constipation. He was diagnosed with intussusception and underwent successful contrast reduction on hospital day 0. The following day, the patient had recurrent symptoms and a repeat contrast enema showed no evidence of recurrent intussusception. A computed tomography scan was obtained, which was concerning for possible recurrence with compromised bowel. He was taken to the operating room for operative reduction and underwent an ileocecetomy with primary handsewn end-to-end anastomosis. His postoperative course was complicated by an anastomotic leak on hospital day 6 necessitating reoperation and creation of an end ileostomy with mucous fistula. He received intravenous metronidazole, ceftriaxone, and ceftazidime antibiotics during his hospital course. On postoperative day 12, the patient developed a sudden increase in ileostomy output, and stool cultures were obtained. His symptoms persisted despite diet modifications, stopping antibiotics, and initiating loperamide. Three days later, stool cultures resulted negative for Escherichia coli, Salmonella, Shigella, Campylobacter species, and Clostridiodes difficile but were positive for methicillin-resistant Staphylococcus aureus. The patient was started on a 10-day course of oral vancomycin and discharged home in good condition 4 days later. After 12 weeks, the patient underwent reversal of the ostomy and is doing well at the 1 month postoperative follow-up, now 5 months from his initial surgery. CONCLUSIONS: To our knowledge, this is the first published report of a toddler being diagnosed with methicillin-resistant Staphylococcus aureus enterocolitis. Because methicillin-resistant Staphylococcus aureus enterocolitis is rare and has overlapping symptoms with more common gastrointestinal pathologies, it is often misdiagnosed. When a patient presents with diarrhea or high ostomy output along with fecal cultures negative for Clostridiodes difficile and other common pathogenic agents, methicillin-resistant Staphylococcus aureus should be considered.

Yersinia pseudotuberculosis Infection Accompanied by Intussusception and Incomplete Kawasaki Disease in a 7-year-old Girl.

Infection with Yersinia pseudotuberculosis, a known causal pathogen of human bacterial gastroenteritis, causes various symptoms and complications. A previously healthy 7-year-old girl was admitted because of fever and gastrointestinal symptoms. She was initially diagnosed with intussusception by abdominal ultrasonography. Although the patient was successfully treated by air enema, the fever persisted. The patient was then diagnosed with incomplete Kawasaki disease based on the presence of four principal clinical features. Intravenous immunoglobulin and oral aspirin were initiated. The patient defervesced and the other symptoms subsided after the treatment. Cardiac ultrasound results showed normal coronary arteries. Because of the gastrointestinal symptoms, stool samples were cultured repeatedly, only to yield normal flora. However, serum levels of anti-Y. pseudotuberculosis-derived mitogen antibody were elevated between the 7th and 18th days of the disease, thereby confirming Y. pseudotuberculosis infection. Because Y. pseudotuberculosis infection results in various clinical manifestations, we must be aware of each symptom and address them systematically.

Predictors of failed enema reduction in children with intussusception: a systematic review and meta-analysis.

OBJECTIVE: To identify predictors of failed enema reduction in children with intussusception. METHODS: PubMed and EMBASE were searched for all studies published over a 20-year time frame, prior to March 25, 2020. Original articles that reported predictors of failed enema reduction were included. The pooled odds ratio (OR) for successful enema reduction according to various features was calculated. The combined estimates were meta-analytically pooled by random-effects modeling. The risk of bias was assessed using the National Institute of Health Quality Assessment Tool. This review was registered to the PROSPERO (CRD42020190178). RESULTS: A total of 38 studies, comprising 40,133 cases, were included. The shorter duration of symptoms (< 24 h; combined OR, 3.812; 95% CI, 2.150-6.759) and abdominal pain (combined OR, 2.098; 95% CI, 1.405-3.133) were associated with the success (all p < 0.001). Age < 1 year (combined OR, 0.385; 95% CI, 0.166-0.893; p = 0.026), fever (combined OR, 0.519; 95% CI, 0.371-0.725; p < 0.001), rectal bleeding (combined OR, 0.252; 95% CI, 0.165-0.387; p < 0.001), and vomiting (combined OR, 0.497; 95% CI, 0.372-0.664; p < 0.001) were associated with the failed reduction. The ascites (combined OR, 0.127; 95% CI, 0.044-0.368; p = 0.001), left-sided intussusception (combined OR, 0.121; 95% CI, 0.058-0.252; p < 0.001), and trapped fluid (combined OR, 0.179; 95% CI, 0.061-0.525; p = 0.017) on US were associated with the failed reduction. CONCLUSIONS: Successful predictors for intussusception reduction have been summarized. This evidence can help identify patients who are more likely to fail non-operative reduction and could be potential surgical candidates. KEY POINTS: • A shorter duration of symptoms and presence of abdominal pain were associated with increased probability of success. • Age (less than 1 year), presence of fever, rectal bleeding, vomiting, and presence of ascites, left-sided intussusception, or trapped fluid on ultrasonography were associated with decreased probability of success. • This study suggests that various clinical and ultrasonography predictors would help identify patients who are more likely to fail nonoperative reduction and identify potential preoperative candidates.

Risk factors for failure of hydrostatic reduction of intussusception in pediatric patients: A retrospective study.

The aim of this current study was to explore the risk factors associated with failure of hydrostatic reduction of intussusception in pediatric patients.Patients with intussusception treated with hydrostatic reduction from January 2010 to December 2016 were retrospectively analyzed. Candidates for inclusion in the study were children from 0 to 18 who were diagnosed with intussusception and treated with hydrostatic reduction. We excluded the patients who had contraindications for hydrostatic reduction, which included peritonitis, perforation signs, and non-responsive shock that required surgery. The data collected included: demographic data (sex, age, and bodyweight), symptoms (vomiting, abdominal pain, rectal bleeding, diarrhea, distention, constipation, and duration of symptoms), signs (temperature, palpable mass, and location of the mass), and other investigations (white blood cell counts, neutrophils, electrolytes, and ultrasound findings).The risk factors for failure of hydrostatic reduction of intussusception were analyzed using the univariable analysis and the multivariable analysis. In the univariable model, the significant risk factors for failure of hydrostatic reduction of intussusception analyzed were age, bodyweight, duration of symptoms, rectal bleeding, constipation, palpable abdominal mass, poor prognosis signs on ultrasound scans and location of mass (the P value for each parameter are stated in ). After the multivariable analysis was done, we found that the significant risk factors for failure of hydrostatic reduction of intussusception were an age of under 1-year-old (OR = 3.915, P = .027), duration of symptoms more than or equal to 48 h (OR = 0.056, P < .001), rectal bleeding (OR = 0.283, P = .003), constipation (OR = 0.086, P < .001), palpable abdominal mass (OR = 0.370, P = .010), and location of mass (left over right side) (OR = 13.782, P < .001).(Table is included in full-text article.)Our study found that an age of under 1-year-old, a duration of symptoms of more than or equal to 48 h, rectal bleeding, constipation, palpable abdominal mass and location of mass (left over right side) were risk factors for the failure of hydrostatic reduction of intussusception.

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. TYPE OF STUDY: Treatment study LEVEL OF EVIDENCE: III.

Intussusception: a rare complication in a patient with acute leukaemia after consolidation chemotherapy.

Intussusception is telescoping of one segment of the gastrointestinal tract into an adjacent one. It is more common in children than adults. When it occurs in adults, it is usually associated with a lead point. Intussusception is very rare in acute leukaemia and has only been reported in few cases. We present a case of an adult woman who presented with intussusception after a cycle of consolidation chemotherapy with high-dose cytarabine for acute myeloid leukaemia. Other causes of acute abdominal pain were excluded, and the diagnosis was established by CT scan of the abdomen and barium enema. No pathological lead points were found intraoperatively. She underwent a right-sided hemicolectomy with complete recovery. To the best of our knowledge, this is only the fourth case of intussusception that has been reported in an adult patient with acute myeloid leukaemia.

Risk factors associated with intestinal necrosis in children with failed non-surgical reduction for intussusception.

BACKGROUND: Intestinal necrosis is the most serious complication of intussusception. The risk factors associated with intestinal necrosis in pediatric patients with intussusception have not been well characterized. OBJECTIVE: This study aimed to investigate the risk factors associated with intestinal necrosis in pediatric patients with failed non-surgical reduction for intussusception. METHODS: Hospitalized patients who failed the air-enema reduction for intussusception in the outpatient department and subsequently underwent surgery were retrospectively reviewed. All cases were categorized into two groups: intestinal necrosis group and non-intestinal necrosis group based on the surgical findings. Demographic and clinical features including the findings from the surgery were recorded and analyzed. Factors associated with intestinal necrosis were analyzed using univariate and multivariate unconditional logistic regression analyses. RESULTS: A total of 728 cases were included. Among them, 171 had intestinal necrosis at the time of surgery. The group with intestinal necrosis had a longer duration of symptom or length of illness (P = 0.000), and younger (P = 0.000) than the non-intestinal necrosis group. Complex/compound type of intussusceptions is more likely to have intestinal necrosis. Multivariate analysis showed that the presence of grossly bloody stool (OR = 2.12; 95% CI 1.19-3.76, P = 0.010) and duration of symptom (OR = 1.07; 95% CI 1.06-1.08, P = 0.000) were independent risk factors for intestinal necrosis in patients hospitalized for surgical reduction for intussusceptions. CONCLUSION: At time of admission, the presence of bloody stools and duration of symptom are the important risk factors for developing intestinal necrosis for those patients who failed non-surgical reduction. The length of illness has the highest sensitivity and specificity to correlate with intestinal necrosis. This finding may suggest that we should take the intussusception cases that have the longer duration of symptom directly to operation room for reduction.

Intussusception in Children Presenting to the Emergency Department: An Asian Perspective.

OBJECTIVE: This project examines the presenting complaints of children with intussusception in the emergency department in an Asian population, with a focus on older children, which has not been well described in previous studies. METHODS: A retrospective study was conducted on children aged 6 months to 15 years, whose conditions were diagnosed with intussusception in KK Women's and Children's Hospital for a 5-year period (2009-2013), based on the case definition established by the Brighton Collaborate Intussusception Working Group. RESULTS: Three hundred ninety-one cases were identified to fulfill the case definition as per the Brighton Collaborative Intussusception Working Group. The mean age of children diagnosed with intussusception is 2.59 years, predominantly in males (65.22%). A total of 3.33% were 10 years or older. Only 3.58% presented with the classical triad-intermittent abdominal pain, vomiting, and bloody stools. In contrast, 22.51% of our Asian patients presented with a triad of intermittent abdominal pain, indrawing of legs, and vomiting. A total of 76.73% of our subjects were treated by air enema only, whereas 22 required surgical treatment after unsuccessful attempts of air enema, and 63 resolved spontaneously, including 7 with ileoileal intussusception. No mortality was documented. CONCLUSIONS: Intussusception is usually diagnosed in the younger population (age <1 year) and predominantly in males. Our study has established that older Asian children can also have intussusception. The classical triad is not a very sensitive diagnostic tool, but the combination of abdominal pain, indrawing of legs, and vomiting may be a more common presenting triad in Asian children.

Predictors of successful air enema reduction of intussusception in infants younger than 4 months.

OBJECTIVES: Intussusception is rare in infants younger than 4 months, and the use of air enema for reduction of intussusception has been limited. In this retrospective study, we analyzed the predictors of successful reduction of intussusception using air enema in infants younger than 4 months. METHODS: This is a retrospective chart review of 97 intussusception patients of younger than 4 months between January 2008 and December 2012. Demographic data, clinical presentation, and outcomes of air enemas were collected and analyzed. We used univariate and multivariate logistic regression analyses for significant predictors of successful reduction of intussusception using air enemas. RESULTS: Of the 97 infants younger than 4 months (median age 97.6 days, age range 41-119 days), 63 (65%) were boys and 34 (35%) were girls. The duration of symptoms ranged from 5 to 53 hours, with a median of 16.3 hours. The clinical features included paroxysmal crying (75%), vomiting (68%), bloody stools (61%), and palpable abdominal masses (32%). The duration of symptoms, bloody stools, and the shape of the intussusceptum were found to be significantly predictive of the outcome of air enema reduction of intussusception. CONCLUSIONS: The rate of successful reduction of intussusception using air enemas in infants younger than 4 months is low. Factors such as the duration of symptoms, bloody stools, and the shape of the intussusceptum are predictive of the outcome of air enema reduction of intussusception.

Waugh syndrome: a report of 7 patients and review of the published reports.

BACKGROUND AND OBJECTIVES: Waugh syndrome (WS) is the association of intussusception and intestinal malrotation. The association is rarely reported in the literature though intussusception is a commonly encountered problem in pediatric patients as a cause of intestinal obstruction. We present our experience in 7 patients with a review of published reports. DESIGN AND SETTING: Retrospective analysis of 7 patients with the diagnosis of Waugh syndrome who were treated at our department between February 1982 to December 2012. PATIENTS AND METHODS: Seven patients with Waugh syndrome presented to our unit during the period February 1982 to December 2012. The clinical findings and management are presented and discussed. RESULTS: Seven patients (three males and four females) presented with intussusception in association with mal.rotation. The age range was from 4 to 11 months; the patients had bilious vomiting and blood in the stool; the diagnosis was confirmed by ultrasound (2), Ba enema (2) and intraoperatively (3). All required operative intervention; either manual reduction or bowel resection and Ladd procedure; one patient died of sepsis; recurrence of obstruction was seen in another patient while the rest did well postoperatively. CONCLUSION: The relationship between intestinal malrotation and intussusceptions may be more frequent than is reported; failure of non-operative management of intussusception may be due to this association and hence brings the attention to its existence. A prospective study is needed to look for intestinal malrotation in patient with intussusceptions who undergo abdominal sonographic examination to determine the true incidence of this association. The anomaly is suspected by presence of a reversed anatomic relationship of the superior mesenteric artery and vein and in such cases to perform an upper gastrointestinal contrast study to define the exact location of the duodenojejuonal (DJ).

Recurrent intussusception.

Recurrent intussusception is defined as an occurrence of intussusception of a bowel loop in a patient with a prior resolution of intussusception, either spontaneously or with an intervention. It is not rare to develop a subsequent episode after a successful reduction of intussusception. We report the cases of 2 children who presented to the emergency department with recurrent intussusception and review the pertinent literature.

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.

Predictors of failed enema reduction in childhood intussusception.

BACKGROUND: Initial management of intussusception is enema reduction. Data are scarce on predicting which patients are unlikely to have a successful reduction. Therefore, we reviewed our experience to identify factors predictive of enema failure. METHODS: A retrospective review of all episodes of intussusception over the past 10 years was conducted. Demographics, presentation variables, colonic extent of intussusceptions, and hospital course were collected. Extent of intussusception was classified as right, transverse, descending, and rectosigmoid. Episodes were grouped as success or failure of enema reduction and compared using the Student t test for continuous variables and χ(2) test for dichotomous variables. Significance was P less than .05. RESULTS: We identified 405 episodes of intussusception and 371 attempts at enema reduction. There were 285 successful enema reductions. There was no difference between groups in age; sex; or the presence of emesis, fever, or abdominal mass. The failed enema group was more likely to have had symptoms over 24 hours before presentation (P = .006), bloody diarrhea (P < .001), and lethargy (P < .001). The chance of success diminished with colonic extent (right, 88%; transverse, 73%; left, 43%; colorectal, 29%; P < .001). CONCLUSION: Predictors of failed enema reduction of intussusception include presence of symptoms over 24 hours, diarrhea, lethargy, and distal extent of intussusception.

Intussusception among Japanese children: an epidemiologic study using an administrative database.

BACKGROUND: The epidemiology of intussusception, including its incidence, can vary between different countries. The aim of this study was to describe the epidemiology of childhood intussusception in Japan using data from a nationwide inpatient database. METHODS: We screened the database for eligible cases ≤ 18 years of age, who were coded with a discharge diagnosis of intussusception (International Classification of Diseases, 10th revision: K-561) between July to December in 2007 and 2008. We then selected cases according to Level 1 of the diagnostic certainty criteria developed by the Brighton Collaboration Intussusception Working Group. We examined the demographics, management, and outcomes of cases, and estimated the incidence of intussusception. RESULTS: We identified 2,427 cases of intussusception. There were an estimated 2,000 cases of infantile intussusception annually in Japan, an incidence of 180-190 cases per 100,000 infants. The median age at diagnosis was 17 months, and two-thirds of the patients were male. Treatment with an enema was successful in 93.0% of cases (2255/2427). The remainder required surgery. Secondary cases accounted for 3.1% (76/2427). Median length of hospital stay was 3 days. Of the 2,427 cases, we found 2 fatal cases associated with intussusception. CONCLUSIONS: This is currently the largest survey of childhood intussusception in Asia using a standardized case definition. Our results provide an estimate of the baseline risk of intussusception in Japan, and it is higher than the risk observed in other countries.

The diagnostic accuracy of an abdominal radiograph with signs and symptoms of intussusception.

OBJECTIVE: The objective of this study was to compare the diagnostic accuracy of an abdominal ultrasound to that of a highly suggestive abdominal radiograph combined with signs and symptoms of intussusception. DESIGN: This was a retrospective cross-sectional study of children 3 years or younger with signs and symptoms of intussusceptions who presented to a pediatric emergency department (ED). Univariate analysis, multivariate analysis, and diagnostic accuracy of clinical characteristics and radiographic findings were derived. RESULTS: A highly suggestive abdominal radiograph (14.80; 5.85-37.45), right upper quadrant mass (8.90; 1.14-69.47), vomiting (2.54; 1.36-4.76), and abdominal pain (2.45; 1.36-4.40) were found to be significantly associated with intussusception by univariate analysis. Vomiting (2.80; 1.34-5.85), abdominal pain (2.75; 1.33-5.69), and bloody stools (2.70; 1.07-6.81) were independently associated with intussusceptions by multivariate analysis. Bloody stools were time dependent. Bloody stools occurred in those patients with intussusception at a median time of 24 hours, from the time the patient started with signs and symptoms to the time of presentation to the ED, vs those without bloody stools presenting at a median time of 11 hours. The combination of a highly suggestive abdominal radiograph, abdominal pain, lethargy, and vomiting was highly specific (95%) for intussusception, comparable to that of an ultrasound (93%). In patients with this combination, all were found to have intussusception by enema or surgery. CONCLUSIONS: Ultrasound is not needed before an enema for the diagnosis of intussusception for those with a highly suggestive abdominal radiograph, abdominal pain, lethargy, and vomiting.

Colocolonic intussusception in a four-yr-old with a heart transplant: a case report and review of the literature.

A rare case of a colocolonic intussusception in a pediatric cardiac transplant patient is reported along with a review of colocolonic intussusception in pediatric patients after organ transplantation. A four-yr-old girl with a history of heart transplantation shortly after birth presented with a 12-hour history of abdominal pain, vomiting, and bloody stools. Initial abdominal x-ray showed rectal edema. A rectal examination revealed a palpable intussusceptum that prompted a therapeutic contrast enema, which failed to reduce the intussusception. Surgical exploration was performed with reduction of the intussusception and resection of the terminal ileum and cecum. A pathologic lead point was not identified.

Perforated appendicitis and appendicolith in a child presenting as intussusception: a case report.

Simultaneous diagnoses of intussusception and appendicitis in the same patient have rarely been described in the pediatric literature. A case of a 30-month-old boy is presented with an initial diagnosis of intussusception that was successfully reduced by air contrast enema. When the patient's condition deteriorated, a diagnostic search surprisingly revealed a missed perforated appendicitis with an appendicolith that had been part of the intussusception. The patient's hospitalization and surgical course is described along with a discussion of the intermingling of intussusception and appendicitis in a young child. This case illustrates the need to consider alternative diagnoses when a patient's course takes an unexpected and confusing turn.
