Clinical predictors and outcome of bowel resection in paediatric intussusception

Scoring System to Evaluate Risk of Nonoperative Management Failure in Children With Intussusception

INTRODUCTION

Typical first-line management of children with intussusception is enema reduction; however, failure necessitates surgical intervention. The number of attempts varies by clinician, and predictors of failed nonoperative management are not routinely considered in practice. The purpose of this study is to create a scoring system that predicts risk of nonoperative failure and need for surgical intervention.

METHODS

Children diagnosed with intussusception upon presentation to the emergency department of a tertiary children's hospital between 2019 and 2022 were retrospectively identified. Univariable logistic regression identified predictors of nonoperative failure used as starting covariates for multivariable logistic regression with final model determined by backwards elimination. Regression coefficients for final predictors were used to create the scoring system and optimal cut-points were delineated.

RESULTS

We identified 143 instances of ultrasound-documented intussusception of which 28 (19.6%) required operative intervention. Predictors of failed nonoperative management included age ≥4 y (odds ratio [OR] 32.83, 95% confidence interval [CI]: 1.91-564.23), ≥1 failed enema reduction attempts (OR 189.53, 95% CI: 19.07-1884.11), presenting heart rate ≥128 (OR 3.38, 95% CI: 0.74-15.36), presenting systolic blood pressure ≥115 mmHg (OR 6.59, 95% CI: 0.93-46.66), and trapped fluid between intussuscepted loops on ultrasound (OR 17.54, 95% CI: 0.77-397.51). Employing these factors, a novel risk scoring system was developed (area under the curve 0.96, 95% CI: 0.93-0.99). Scores range from 0 to 8; ≤2 have low (1.1%), 3-4 moderate (50.0%), and ≥5 high (100%) failure risk.

CONCLUSIONS

Using known risk factors for enema failure, we produced a risk scoring system with outstanding discriminate ability for children with intussusception necessitating surgical intervention. Prospective validation is warranted prior to clinical integration.

Rotavirus vaccination is a protective factor for adverse outcomes in primary intussusception: a single-center retrospective study

Background

The clinical features and prognosis of intussusception in children vaccinated against rotavirus were undefined. Hence, we conducted the study to explore the clinical characteristics and outcomes of primary intussusception patients who received rotavirus vaccine.

Methods

A single-center retrospective study was performed in 327 primary intussusception patients between January 2019 and December 2021. Of these, 168 were vaccinated against rotavirus and 159 were not, the latter serving as the control group. Data on patients' clinical characteristics, commonly used inflammatory biomarkers, treatment, and outcomes were collected and evaluated.

Results

Most of the vaccination group received pentavalent rotavirus vaccine produced by Merck, USA (89.88%). There were no differences in demographic characteristics, time from onset to hospital attendance, clinical symptoms and signs between the vaccination group and the control group. The success rate of air enema reduction in the vaccination group was higher than that in the control group (98.21% vs. 88.68%, q=0.01). The vaccination group had lower rates of surgery and complication (1.79% vs. 11.32%, q=0.008; 2.98% vs. 12.58%, q=0.006). Both platelet-lymphocyte ratio (PLR) and C-reactive protein (CRP) levels were lower in the vaccinated group (q=0.02, q=0.004). Higher CRP level [odds ratio (OR): 1.635; 95% confidence interval (CI): 1.248-2.143; P=0.006] and the longer time from onset to hospital attendance (OR: 3.040; 95% CI: 2.418-12.133; P=0.01) were associated with increased adverse events. Rotavirus vaccination (OR: 0.527; 95% CI: 0.103-0.751; P=0.02) was associated with a reduction in the probability of adverse events.

Conclusions

Adverse events such as surgery and complications were lower in the vaccination group. Rotavirus vaccination was an independent protective factor for adverse events in patients with primary intussusception.

Clinical presentation and management outcome of pediatric intussusception at Wolaita Sodo University Comprehensive Specialized Hospital: a retrospective cross-sectional study

OBJECTIVE

To assess the pattern of clinical presentations and factors associated with the management outcome of pediatric intussusception among children treated at Wolaita Sodo University Comprehensive Specialized Hospital, Ethiopia.

METHODS

This retrospective cross-sectional study included the medical records of 103 children treated for intussusception from 2018 to 2020. The data collected were analyzed using SPSS 25.0 (IBM Corp., Armonk, NY, USA).

RESULTS

In total, 84 (81.6%) patients were released with a favorable outcome. Ileocolic intussusception was a positive predictor, with a nine-fold higher likelihood of a favorable outcome than other types of intussusception [adjusted odds ratio (AOR), 9.16; 95% confidence interval (CI), 2.39-21.2]. Additionally, a favorable outcome was three times more likely in patients who did than did not undergo manual reduction (AOR, 3.08; 95% CI, 3.05-5.48). Patients aged <1 year were 96% less likely to have a positive outcome than those aged >4 years (AOR, 0.04; 95% CI, 0.03-0.57).

CONCLUSION

Most patients were discharged with favorable outcomes. Having ileocolic intussusception and undergoing manual reduction were associated with significantly more favorable outcomes of pediatric intussusception. Therefore, nonsurgical management such as hydrostatic enema and pneumatic reduction is recommended to reduce hospital discharge of patients with unfavorable outcomes.

Trends in childhood intussusception in a Nigerian tertiary hospital

Background

Early presentation, high rate of successful non-operative treatment, low morbidity and mortality in childhood intussusception is common in High and Upper Middle-Income Countries but not in many Lower middle- and Low-income countries.

Aim

To assess the trends in the profile, treatment modalities and outcomes of intussusception in our hospital.

Materials and methods

Retrospective study over a 12-year period divided into two 6-year periods. Data entry/analysis was done using SPSS and various indices were compared between these two periods. Two-tailed t-test for two independent means was used to compare means while two-tailed Fisher exact tests were used to compare categorical variables. Results were presented as tables, means, ranges, percentages and a p-value less than 0.05 was deemed statistically significant.

Results

There was a significant increase in the proportion of successful non-operative treatment (18.6% vs 34%, p=0.03), reduction in the incidence of operative manual reduction (27.1% vs 12.8%; p=0.026), reduction in operative treatment (78.5% vs 63.9%, p=0.034), increased utilization of pre-intervention ultrasound (75% vs96.7%, p<0.0001) and reduction in hospital stay duration (10.47 ±7.95days vs 7.24±4.86 days; p=0.004).

Conclusions

Contribution of successful non-operative treatment to the overall treatment of intussusception significantly increased while that of operative manual reduction significantly reduced and bowel resection showed no change. Preoperative utilization of ultrasonography significantly increased while mean duration of admission reduced significantly, but late presentation, morbidity and mortality rates had no significant changes.

Clinical characteristics of pediatric intussusception and predictors of bowel resection in affected patients

Background

Surgery is required for the treatment of intussusception when enema reduction is unsuccessful, or when the patient develops peritonitis, bowel perforation, or intestinal damage. We aimed to evaluate the clinical and laboratory parameters that may be used to predict the need for bowel resection in children with intussusception.

Methods

This observational retrospective study included children who were admitted to the pediatric emergency department with intussusception. Univariate and multivariate logistic regression models were used to evaluate factors associated with bowel resection.

Results

In total, 584 children with intussusception were admitted to the pediatric emergency department; 129 of these children underwent surgery. Multivariate analysis revealed the following independent predictors of bowel resection for intussusception: symptoms for at least 2 days before surgery (OR = 6.863; p = 0.009), long intussusception (OR = 5.088; p = 0.014), pathological lead point (OR = 6.926; p = 0.003), and intensive care unit admission (OR = 11.777; p = 0.001) were factors independently associated with bowel resection.

Conclusion

Symptoms for at least 2 days before surgery, long intussusception, pathological lead, and intensive care unit admission were predictors of bowel resection in children with intussusception. These findings can be used to identify patients at high risk of needing surgery and bowel resection.

Temporal Validation of Chiang Mai University Intussusception Failed Reduction Score (CMUI)

This study aimed to validate the “Chiang Mai University Intussusception Failed Score (CMUI)” for intussusception non-operative reduction. Both a 2-year retrospective and a 5-year prospective consecutive review of patients with intussusception were conducted. Data were collected from January 2013 to December 2020. Related retrospective data of a developmental set from two centers from January 2006 to December 2012 were used. Ten prespecified prognostic factors for failed reduction were collected and from these a predictive score was calculated. The actual results of non-operative reduction were collected and set as a reference standard. Altogether, 195 episodes of intussusception were found. Twenty-two patients were excluded due to contraindications; therefore, a total of 173 episodes were included in the validation dataset. The development data set comprised 170 episodes. We found that no statistical significance was found from comparing the areas under the ROC of two datasets (p-value = 0.31), while specificity of the validation set was 93.8% (88.1–97.3). This temporal validation showed a high specificity and a high affinity for prediction of failed reduction as the development dataset despite being in an era of a higher successful reduction rate. The intensive reduction protocols might be introduced among patients with high-risk scores.

Clinical profile and treatment outcome of acute intussusception among children in eastern Ethiopia: A seven years retrospective study

BACKGROUND

Acute intussusception is the main cause of abdominal surgical emergencies worldwide in young children, with an incidence of approximately 1 to 4 per 2,000 children. An accurate estimate of the treatment outcomes of acute intussusception in children is unknown in low-and middle-income countries like Ethiopia. Hence, this study aimed to determine the clinical profile, treatment outcomes of acute intussusception and its associated factors among children admitted to Hiwot Fana Specialized University Hospital in eastern Ethiopia.

METHODS

An institutional-based retrospective cross-sectional study was conducted from November 01 to 30, 2021, among children admitted and managed for acute intussusception. All medical records of children admitted and managed for acute intussusception at Hiwot Fana Specialized University hospital between January 2014 and December 2020 were included. Data were collected using pretested structured checklists through a review of medical records, entered and analyzed using Statistical Package for Social Sciences version 25.0. Chi-square (χ ²) tests were applied to determine the associated factors with treatment outcome. The statistical significance was considered at a p-value < 0.05.

RESULTS

In this chart review of children, 13.3% (95% CL: 11.8-14.8) died. The median age of the study participant was 13 months. The majority, 72% were male and 76% were less than 24 months old. Regarding the clinical profile; abdominal pain (94.7%), vomiting (93.3%), bloody diarrhea (70.7%), and abdominal distention (76.0%) were the most common clinical presentations. Age less than 24 months [X ²= 8.13 (df = 1); p = 0.004], preoperative vital signs [X ²= 19.21 (df = 2); p = 0.000], intraoperative findings [X ²= 18.89 (df = 1); p = 0.000], and postoperative complications [X ²= 14.60 (df = 1); p = 0.000] were significantly associated with treatment outcome of acute intussusception.

CONCLUSION

In this chart review, the overall mortality rate in children was relatively high. One in seven children died from acute intussusception. Age less than 24 months, preoperative vital signs, intraoperative findings, and postoperative complications were significantly associated with acute intussusception treatment outcomes. Surgical management was the only treatment performed in all cases. Delayed presentation of patients and lack of other treatment modalities such as non-surgical interventions are serious concerns in this facility. The initiation of non-surgical reduction may reduce the need for surgical intervention-related complications, and child mortality.

Evaluation of spontaneous reduction among the invagination cases admitted to the paediatric emergency department; retrospective study

AIMS

We aimed to determine the factors that determine the conditions in cases of invagination with spontaneous reduction.

METHODS

Study was conducted retrospectively in the Paediatric Emergency Department (PED) of the tertiary University Hospital in Ankara, Turkey. Invagination cases admitted between January 1, 2019 and December 31, 2019 were included in the study. Patient information (demographic data such as age, gender, physical examination findings, laboratory and imaging methods, treatment and follow-up) were recorded on the data form prepared by the researchers before the study, using patient files and hospital patient information system. Data were analysed with IBM SPSS V23.

RESULTS

During the study period, the number of cases who applied to the PED was 33,849 and 74 of these cases were diagnosed with invagination. In the cases diagnosed with invagination, 69 (93%) of them spontaneously reduced during the follow-up. Among all cases, the male sex ratio was 56.5% (39/69). The average age was 44.6 months (minimum: 6; maximum: 154). The mean follow-up time in the emergency room was 12 hours and in the hospital service was 38 hours. Vomiting was observed in 89.9% (58/69) of all cases, abdominal pain in 68.1% (44/69) and rectal bleeding in 1.4% (1/69).The invagination of 21.7% (15/69) of the patients at the first USG was ileo-ileal. 63.8% (44/69) of the patients were discharged after followed up in emergency observation. The number of USGs was lower in the group that was discharged after the follow-up in the emergency room, than the follow-up groups in the service monitoring (P = .012).

CONCLUSION

Invagination is one of the surgical emergencies. With the widespread use of USG, most of these cases are followed up by clinical and USG follow-up in paediatric emergency services. Spontaneous reduction frequently develops in cases of intussusception with small bowel localisation and short bowel segment (less than 3 cm).
