Medical Alert Cards for patients with an anorectal malformation: a useful tool to increase awareness

PURPOSE

Anorectal malformations (ARMs) are rare congenital anomalies causing altered anatomy and frequent hospitalizations. Parental awareness and clear communication are crucial in family-centered care. This study assesses the impact of patient-held ARM Medical Alert Cards on healthcare providers and caregivers.

METHODS

Caregivers of children with ARMs, including cloacal anomalies, received Medical Alert Cards with (1) contact details; (2) disease-related information; and (3) patient-specific data. A survey evaluated these cards' effectiveness in enhancing ARM awareness among healthcare professionals and caregivers.

RESULTS

Among 33 respondents, 29 (88%) found the cards helpful in increasing ARM awareness. Both caregivers and providers found the content coherent, with a median readability score of 9 (IQR 8-10). The card layout was well-received by 30 out of 32 respondents (94%), and all noted the clarity of the contact details, facilitating patient referrals to specialized care. Most caregivers (13 out of 14, 93%) expressed willingness to use these cards in medical settings. Suggestions for improvement included adding more patient-specific information, enhancing readability, and providing visual anatomy diagram.

CONCLUSION

Medical Alert Cards for patients with ARMs can enhance understanding of ARMs among caregivers and healthcare providers, serving as a vital tool in patient-centered management strategies tailored to individual needs.

Evaluation and Management of Total Colonic Hirschsprung Disease: A Comprehensive Review From the American Pediatric Surgical Association (APSA) Hirschsprung Disease Interest Group

BACKGROUND

Children with total colonic Hirschsprung disease (TCHD) are a unique group of patients with pre- and postoperative management challenges. This review provides a rational, expert-based approach to diagnosing and managing TCHD.

METHODS

The guidelines were developed by the Hirschsprung Disease Interest Group members established by the American Pediatric Surgical Association (APSA) Board of Governors. Group discussions, literature review, and expert consensus were used to summarize the current knowledge regarding diagnosis, staged approach, the timing of pull-through, and pre-and postoperative management in children with TCHD.

RESULTS

This paper presents recommendations for managing TCHD before and after reconstruction, including diagnostic criteria, surgical approaches, bowel management, diet, antibiotic prophylaxis, colonic irrigations, and post-surgical considerations.

CONCLUSIONS

A clear understanding of the unique challenges posed by TCHD and consensus on its treatment are lacking in the literature. This review standardizes this patient group's pre- and postoperative management.

Medical Costs of Patients Undergoing Esophageal Atresia Repair are Mainly Influenced by Associated Malformations

BACKGROUND

 Esophageal atresia (EA) is a rare disease requiring surgical repair, usually within the first days of life. Patients with EA require intensive postoperative care and often have comorbidities. There is a lack of data on the costs incurred by patients with EA during the first year of life.

METHODS

 Anonymized claims data were provided by the Techniker Krankenkasse (∼10.8 million clients). Data were extracted for patients who had an inpatient diagnosis of EA (International Classification of Diseases [ICD]: Q39.0 or Q39.1) and a reconstruction of the esophageal passage in case of atresia (Operationen-und Prozedurenschlüssel [German version of ICPM, International Classification of Procedures in Medicine; OPS] 5-428.0 to 5-428.7, 5-316.1 or 5-431.0) during their first hospital stay. All patients were in their first year of life at initial hospitalization (2016-2020) and were followed up for 1 year. Costs, length of hospital stay, and duration of mechanical ventilation and differentiated OPS services were analyzed using descriptive statistics. Multiple linear regression was used to analyze the determinants of hospital costs.

RESULTS

 A total of 119 patients with EA were included (55.5% male). The mean cost of the 1-year observation period was €89,736 ± 97,419 (range €12,755-640,154). The increasing costs of the initial hospitalization led to a disproportionate increase in the costs of the 1-year observation period. The presence of an associated malformation combined with surgical complications was associated with almost five-fold higher costs than in patients without an associated malformation and an uncomplicated course (€193,103 ± 157,507 vs. €39,846 ± 33,473). The mean duration of mechanical ventilation was 23.2 ± 43.1 days and the mean length of hospital stay was 80.3 ± 77.2 days.

CONCLUSION

 To our knowledge, this is the first study to investigate the costs of EA patients in the first year of life. The presence of an associated malformation combined with surgical complications was associated with almost five-fold higher costs than in patients without an associated malformation and an uncomplicated course.

ERN eUROGEN Guidelines on the Management of Anorectal Malformations, Part IV: Organization of Care and Communication between Providers

INTRODUCTION

 Being born with an anorectal malformation (ARM) can have profound and lifelong implications for patients and parents. Organization of care and communication between health care providers is an overlooked area of patient care. The European Reference Network eUROGEN for rare and complex urogenital conditions assembled a panel of experts to address these challenges and develop comprehensive guidelines for the management of ARM.

METHODS

 The Dutch Quality Standard for ARM served as the basis for the development of guidelines. Literature was searched in Medline, Embase, and Cochrane. The ADAPTE method was utilized to incorporate the newest available evidence. A panel of 15 experts from seven European countries assessed currency, acceptability, and applicability of recommendations. Recommendations from the Dutch Quality Standard were adapted, adopted, or rejected and recommendations were formed considering all available evidence, expert consensus, and the European context.

RESULTS

 Aspects pertaining to organization of care, patient/parent/health care provider communication, and referral and collaboration between providers caring for ARM patients were assessed. Two new studies were identified. In total, the panel adapted 12 recommendations, adopted 7, and developed 2 de novo. The overall level of newly found evidence was considered low and most recommendations were based on expert opinion.

CONCLUSION

 Collaborative care and organization of care are gaining importance in the field of ARM. This guideline gives practical guidance on how to achieve better communication and collaboration between all involved parties, applicable at the European level.

Development and Validation of a Realistic Neonatal Intestinal Jejunoileal Atresia Simulator for the Training of Pediatric Surgeons

Background: Neonatal surgical pathology presents highly technical complexity and few opportunities for training. Many of the neonatal surgical entities are not replicable in animal models. Realistic 3D models are a cost-effective and efficient alternative for training new generations of pediatric surgeons. Methods: We conceptualized, designed, and produced an anatomically realistic model for the open correction of jejunoileal atresia. We validated it with two groups of participants (experts and non-experts) through face, construct, and content validity questionnaires. Results: The model was validated by eleven experts and nine non-experts. The mean procedure time for the experts and non-experts groups was 41 and 42 min, respectively. Six non-experts and one expert did not complete the procedure by the designed time (45 min) (p = 0.02). The mean score of face validity was 3.1 out of 4. Regarding construct validity, we found statistically significant differences between groups for the correct calculation of the section length of the antimesenteric border (Nixon's technique) (p < 0.01). Concerning content validity, the mean score was 3.3 out of 4 in the experts group and 3.4 out of 4 in the non-experts group. Conclusions: The present model is a realistic and low-cost valid option for training for open correction of jejunoileal atresia. Before drawing definitive conclusions, future studies with larger sample sizes and blinded validators are needed.

Importance of Adequate Surgical Local Control in Fusion-Negative Para-Testicular Rhabdomyosarcoma: Data From the Cooperative Weichteilsarkom Studiengruppe Trials (CWS-96 and CWS-2002P) and the European Soft Tissue Sarcoma Registry (SoTiSaR)

BACKGROUND

This study aimed to assess the impact that the quality of primary and subsequent surgeries has on the survival of patients with para-testicular rhabdomyosarcoma (PTRMS).

METHODS

Patients with localized (IRS I-III) and metastatic (IRS IV) PTRMS were enrolled in the two Cooperative Weichteilsarkom Studiengruppe (CWS) trials (CWS-96, CWS-2002P) and the Soft Tissue Sarcoma Registry (SoTiSaR).

RESULTS

Among 196 patients (median age, 8.4 years), 106 (54.1%) had primary complete resection. Image-defined lymph node (LN) disease was detected in 21 (11.5%) patients in the localized cohort and 12 (92.3%) patients in the metastatic cohort. The 5-year event-free survival (EFS) and overall survival (OS) were respectively 87.3% and 94.0% for the patients with localized PTRMS and 46.2% and 42.2% for the patients with metastatic PTRMS. Protocol violations during the primary surgery (PV-PS) were observed in 70 (42%) of the IRS I-III patients. This resulted in higher rates of R1/R2 resections (n = 53 [76%] vs n = 20 [21%]; p < 0.001) with a need for pretreatment re-excision (PRE) (n = 50 [83%] vs n = 10 [17%]; p < 0.001) compared with the patients undergoing correct primary surgery. Protocol violations during PRE occurred for 13 (20%) patients. Although PV-PS did not influence the 5-year EFS or OS in the localized PTRMS cohort, the unadjusted log-rank test showed that R status after PRE is a prognostic factor for 5-year OS (R1 vs R0 [81.8% vs 97.6%]; p = 0.02).

CONCLUSIONS

The quality of surgical local control in PTRMS is unsatisfactory. Emphasis should be placed on evaluating the resection status after PRE in further clinical trials.

Treatment of Esophageal Atresia in Germany: Analysis of National Hospital Discharge Data From 2016 to 2022

BACKGROUND

Esophageal atresia (EA) is a complex malformation. Multidisciplinary management is necessary, with the operative repair being the most challenging step in the treatment algorithm. The complete care structure for children with EA in Germany has not been analyzed yet.

METHODS

In the observed period 2016-2022, inpatient EA cases were analyzed 1) during the hospital stay of birth, and 2) during the hospital stay of corrective surgery in patients aged up to 365 days, both based on national hospital discharge data. Patients' comorbidities, hospital caseload, treatment characteristics (e.g. surgical approach) and outcome parameters were analyzed.

RESULTS

1) 1190 newborn EA cases were treated in 260 hospitals during the perinatal period. 54% had at least one additional malformation, and 16% had a birthweight below 1500 g. In-hospital mortality was 8.4%. 2) 1475 corrective operations for EA were performed in 111 hospitals with a consistent median annual caseload of 2 (P25-P95 1-8) per hospital. At least one indicator for a complicated perioperative course was documented in 63.7% of cases. The use of bronchoscopy was coded in 50% of cases. Median ventilation time during the entire hospital stay was 176 h (P25-P95: 95-1759 h).

CONCLUSIONS

Newborns with EA are complex and early postoperative complications are common. The care structure is decentralized, and there was no trend towards centralization in the observed period. The low documented use of bronchoscopy is noteworthy. Centralization of the highly complex and schedulable corrective surgery for EA is necessary to evaluate outcomes and might improve the quality of care and resource utilization. CATEGORY OF THE MANUSCRIPT AND TYPE OF STUDY: original article, observational cross-sectional study, secondary data analysis.

Influence of surgical volume on the mortality and morbidity of gastrointestinal perforation in children

PURPOSE

To clarify the influence of surgical volume on the mortality and morbidity of gastrointestinal perforation in children in Japan.

METHODS

We collected data on pediatric patients with gastrointestinal perforation between 2017 and 2019, from the National Clinical Database. The surgical volumes of various institutions were classified into three groups: low (average number of surgeries for gastrointestinal perforation/year < 1), medium (≥ 1, < 6), and high (≥ 6). The observed-to-expected (o/e) ratios of 30-day mortality and morbidity were calculated for each group using an existing risk model.

RESULTS

Among 1641 patients (median age, 0.0 years), the 30-day mortality and morbidity rates were 5.2% and 37.7%, respectively. The 30-day mortality rates in the low-, medium-, and high-volume institutions were 4.9%, 5.3%, and 5.1% (p = 0.94), and the 30-day morbidity rates in the three groups were 26.8%, 39.7%, and 37.7% (p < 0.01), respectively. The o/e ratios of 30-day mortality were 1.05 (95% confidence interval [CI] 0.83-1.26), 1.08 (95% CI 1.01-1.15), and 1.02 (95% CI 0.91-1.13), and those of 30-day morbidity were 1.72 (95% CI 0.93-2.51), 1.03 (95% CI 0.79-1.28), and 0.95 (95% CI 0.56-1.33), respectively.

CONCLUSION

Surgical volume does not have significant impact on the outcomes of pediatric gastrointestinal perforation in Japan.

Development of a Standardized Algorithm for Management of Newly Diagnosed Anorectal Malformations

Neonates with a new diagnosis of anorectal malformation (ARM) present a unique challenge to the clinical team. ARM is strongly associated with additional midline malformations, such as those observed in the VACTERL sequence, including vertebral, cardiac, and renal malformations. Timely assessment is necessary to identify anomalies requiring intervention and to prevent undue stress and delayed treatment. We utilized a multidisciplinary team to develop an algorithm guiding the midline workup of patients newly diagnosed with ARM. Patients were included if born in or transferred to our neonatal intensive care unit (NICU), or if seen in clinic within one month of life. Complete imaging was defined as an echocardiogram, renal ultrasound, and spinal magnetic resonance imaging or ultrasound within the first month of life. We compared three periods: prior to implementation (2010-2014), adoption period (2015), and delayed implementation (2022); p ≤ 0.05 was considered significant. Rates of complete imaging significantly improved from pre-implementation to delayed implementation (65.2% vs. 50.0% vs. 97.0%, p = 0.0003); the most growth was observed in spinal imaging (71.0% vs. 90.0% vs. 100.0%, p = 0.001). While there were no differences in the rates of identified anomalies, there were fewer missed diagnoses with the algorithm (10.0% vs. 47.6%, p = 0.05). We demonstrate that the implementation of a standardized algorithm can significantly increase appropriate screening for anomalies associated with a new diagnosis of ARM and can decrease delayed diagnosis. Further qualitative studies will help to refine and optimize the algorithm moving forward.

Swedish registry study showed that 50% of paediatric operations were performed in university hospitals and mortality was low

AIM

To investigate the distribution of paediatric surgery in various hospitals and to study postoperative risk factors of mortality.

METHODS

Retrospective registry-based cohort study of children aged 0-14 years undergoing surgery from 2017 to 2021. Data were extracted from the Swedish Perioperative Registry. A mixed logistic regression was applied for the all-risk mortality analysis.

RESULTS

A total of 126 539 cases were identified, 50% in university, 36% in county and 14% in district hospitals. The dominating operations were appendectomy in 6667, orchidopexy in 5287, inguinal hernia repair in 4200 and gastrostomy in 1152 children. Among children under 1 year of age or American Society of Anesthesiologists Physical Status classification (ASA-PS-Class) 3-5, the majority underwent surgery in university hospitals. The 30-day mortality in university hospitals was 0.5% and in county hospitals 0%. The proportion of emergency surgery was similar in university and county hospitals. Independent risk factors of mortality were being under 1 year of age, ASA-PS-class 4-5, emergency surgery and surgery at university hospitals.

CONCLUSION

Half of all operations in children were performed in university hospitals, with low postoperative mortality despite effective centralisation of high risk patients <1 year of age or ASA-PS-Class 3-5.

Trends in Management of Fetuses with Suspected Lower Urinary Tract Obstruction (LUTO): A High-Risk Fetal and Pediatric Center Experience in a Universal-Access-to-Care System

INTRODUCTION

 Neonates with lower urinary tract obstruction (LUTO) experience high morbidity and mortality associated with the development of chronic kidney disease. The prenatal detection rate for LUTO is less than 50%, with late or missed diagnosis leading to delayed management and long-term sequelae in the remainder. We aimed to explore the trends in prenatal detection and management at a high-risk fetal center and determine if similar trends of postnatal presentations were noted for the same period.

METHODS

 Prenatal and postnatal LUTO databases from a tertiary fetal center and its associated pediatric center between 2009 and 2021 were reviewed, capturing maternal age, gestational age (GA) at diagnosis, and rates of termination of pregnancy (TOP). Time series analysis using autocorrelation was performed to investigate time trend changes for prenatally suspected and postnatally confirmed LUTO cases.

RESULTS

 A total of 161 fetuses with prenatally suspected LUTO were identified, including 78 terminations. No significant time trend was found when evaluating the correlation between time periods, prenatal suspicion, and postnatal confirmation of LUTO cases (Durbin-Watson [DW] = 1.99, p = 0.3641 and DW = 2.86, p = 0.9113, respectively). GA at referral was 20.0 weeks (interquartile range [IQR] 12, 35) and 22.0 weeks (IQR 13, 37) for TOP and continued pregnancies (p < 0.0001). GA at initial ultrasound was earlier in terminated fetuses compared to continued (20.0 [IQR 12, 35] weeks vs. 22.5 [IQR 13, 39] weeks, p < 0.0001). While prenatal LUTO suspicion remained consistently higher than postnatal presentations, the rates of postnatal presentations and terminations remained stable during the study years (p = 0.7913 and 0.2338), as were GA at TOP and maternal age at diagnosis (p = 0.1710 and 0.1921).

CONCLUSION

 This study demonstrated that more severe cases of LUTO are referred earlier and are more likely to undergo TOP. No significant trend was detected between time and prenatally suspected or postnatally confirmed LUTO, highlighting the need for further studies to better delineate factors that can increase prenatal detection.

Surgical Simulation of Posterior Sagittal Anorectoplasty for Rectovestibular Fistula: Low-Cost High-Fidelity Animal-Tissue Model

PURPOSE

To provide a high-fidelity, animal tissue-based model for the advanced surgical simulation of a Posterior Sagittal Anorectoplasty (PSARP) for rectovestibular fistula in anorectal malformation (ARM).

MATERIALS AND METHODS

A chicken cadaver was used to assess the feasibility of simulating a PSARP for rectovestibular fistula in ARM. No modification was required to implement the surgical simulation.

RESULTS

A detailed description of the high-fidelity surgical simulation model is provided. The PSARP can be simulated while providing realistic anatomy (e.g. common wall between rectovestibular fistula and vagina), adequate rectal size, location and placement of the rectovestibular fistula, and proximity to the vagina. Haptic conditions of the tissue resemble human tissue and operative conditions as well.

DISCUSSION

Concerning the decreased exposure of index cases of pediatric surgical trainees and pediatric surgeons in practice, simulation-based training can provide means to acquire or maintain the necessary skills to perform complex surgical procedures [1-5] Surgical simulation models for ARM are limited. Few low-cost trainers are available with predominant artificial and mostly unrealistic tissue [6-8] Animal models have the advantage of realistic multilayer tissue haptic feedback [6].

CONCLUSION

We provide a low-cost, high-fidelity model for correcting a rectovestibular fistula in a child with ARM, a complex operative procedure with low incidence but high-stake outcomes. The described tissue model utilizing the chicken cloaca anatomy provides a high-fidelity model for operative correction of rectovestibular ARM. For simulation purposes in the treatment of ARM, this model appears to be promising in terms of providing realistic pathology and haptic feedback in pediatric dimensions.
