Global survey on point-of-care ultrasound (pocus) use in child surgery.

PURPOSE: To undertake a global assessment of existing ultrasound practices, barriers to access, point-of-care ultrasound (POCUS) training pathways, and the perceived clinical utility of POCUS in Child Surgery. METHODS: An electronic survey was disseminated via the GICS (Global Initiative of Children's Surgery) network. 247 anonymized responses from 48 countries were collated. 71.3% (176/247) worked in child surgery. RESULTS: Ultrasound was critical to practice with 84% (147/176) of requesting one daily or multiple times per week. Only 10% (17/176) could access emergency ultrasound < 1 h from request. The main barrier was a lack of trained personnel. HIC surgeons were more likely to have ultrasound training (24/29; 82.8%) compared with LMICs (74/147; 50.3%) (p = .001319; CI 95%). Self-perceived POCUS competence was associated with regularity of POCUS use (p < 0.001; CI 95%). Those who already practice POCUS most commonly use it for trauma, intussusception, and ultrasound-guided procedures. Majority (90%; 159/176) of child surgeons would attend formal POCUS training if available. CONCLUSIONS: Ultrasound is critically important in children's surgery globally, however, many surgeons experience barriers to timely access. There is a strong interest in learning POCUS for relevant pediatric surgical applications. Further research is needed to evaluate the best methods of training, accreditation, and governance.

Influence of Diet on Bowel Function and Abdominal Symptoms in Children and Adolescents with Hirschsprung Disease-A Multinational Patient-Reported Outcome Survey.

Introduction: This study aimed to understand the influence of diet and nutrition items on gastrointestinal symptoms in patients with Hirschsprung Disease (HD). Method: An online questionnaire was created to obtain patient-reported outcomes using the multinational Holistic Care in Hirschsprung Disease Network. This was distributed in Dutch, English, German, Italian, Polish, and Swedish via patient associations. Information on demographics, the extension of disease, current diet, and the influence of food ingredients on bowel function were obtained. Results: In total, 563 questionnaires were answered by parents or patients themselves. The length of the aganglionic segment was short in 33%, long in 45%, total colonic aganglionosis (TCA) in 11%, and involved the small intestine in 10%. Overall, 90% reported following a mixed diet, and 31% reported taking probiotics, with twice as many patients taking probiotics in the TCA group compared to standard HD. Mealtimes and behaviours around eating were affected by 61%, while 77% had established food items that worsened symptoms, and of these, 80% stated that they had worked these items out themselves. A high-fibre diet was followed by 24% and 18% a low-fibre diet. Symptoms were reported, particularly from dairy in 30%, fruits in 39%, pulses in 54%, and sugar in 48%. Conclusions: This first multinational survey on diet and bowel function in HD reports an association between certain dietary items with gastrointestinal symptoms. This study can support an improved understanding of the interaction between food items and bowel function in children with HD. We suggest a multidisciplinary approach to balance dietary exclusions and support adequate growth, preventing nutrition deficiencies and enhancing quality of life.

Improving care and survival of newborns with surgical conditions in Tanzania (TINY Tanzania): a focus on gastroschisis.

PURPOSE: Gastroschisis is associated with over 90% mortality in many sub-Saharan African countries. The introduction of the Gastroschisis Care Bundle at Muhimbili National Hospital (MNH) increased survival up to 60%. We aim to explain the impact of using implementation science methods to decentralize the care of babies with gastroschisis to other parts of Tanzania. METHODS: We used a Step-Wedge Implementation Science design to scale up gastroschisis care through training of providers, dissemination and current revision of evidence-based care protocols, advocacy, and engagement with stakeholders. We used mixed methods for data collection. Anonymous patient and provider evaluation data were collected using a nationwide Gastroschisis Database via REDCap. We evaluated the implementation and effectiveness of the care bundle in different hospitals in Tanzania. RESULTS: Decentralizing care nationally was feasible, acceptable, and adaptable. A total of nine trainings have been conducted training 420 providers (14 Master Trainers) reaching seven regions of Tanzania. The three advocacy national campaigns have ensured community reach and patient engagement. A countrywide gastroschisis database was developed to collect data on patients with gastroschisis, hosted locally at MNH with 332 patients' data entered in 1 year. The majority (90.2%) were treated using preformed silo bags with an overall survival of 28.5% in all centers. Late presentation and infection remain to be the main challenge. CONCLUSION: To achieve quality and sustainable surgical care, there is a need to design, implement, evaluate, and continuously improve context-relevant strategies to achieve and sustain the survival of neonates with congenital anomalies. Decentralization enables clear connectedness of hospitals, bringing care closer to patients.

Depth of intact vascular plexus - visualized with optical coherence tomography - correlates to burn depth in thoracic thermic injuries in children.

Objectives: Deep thermal injuries are among the most serious injuries in childhood, often resulting in scarring and functional impairment. However, accurate assessment of burn depth by clinical judgment is challenging. Optical coherence tomography (OCT) provides structural images of the skin and can detect blood flow within the papillary plexus. In this study, we determined the depth of the capillary network in healthy and thermally injured skin and compared it with clinical assessment. Methods: In 25 children between 7 months and 15 years of age (mean age 3.5 years (SD±4.14)) with thermal injuries of the ventral thoracic wall, we determined the depth of the capillary network using OCT. Measurements were performed on healthy skin and at the center of the thermal injury (16 grade IIa, 9 grade IIb). Comparisons were made between healthy skin and thermal injury. Results: The capillary network of the papillary plexus in healthy skin was detected at 0.33 mm (SD±0.06) from the surface. In grade IIb injuries, the depth of the capillary network was 0.36 mm (SD±0.06) and in grade IIa injuries 0.23 mm (SD±0.04) (Mann-Whitney U test: p<0.001). The overall prediction accuracy is 84 %. Conclusions: OCT can reliably detect and differentiate the depth of the capillary network in both healthy and burned skin. In clinical IIa wounds, the capillary network appears more superficial due to the loss of the epidermis, but it is still present in the upper layer, indicating a good prognosis for spontaneous healing. In clinical grade IIb wounds, the papillary plexus was visualized deeper, which is a sign of impaired blood flow.

Surgical Strategies in Total Colonic Aganglionosis: Primary Pullthrough-Pathway of Care.

Background: Total colonic aganglionosis, as a rare variant of Hirschsprung Disease, still poses challenges to surgeons in terms of diagnosis and management. The optimal preparation for pullthrough is crucial for reconstructive surgery. This study aims to explore our surgical pathway for children with total colonic aganglionosis (TCA) and to describe the prehabilitation necessary to prepare for successful reconstructive pullthrough surgery. Methods: A prospective review of children with TCA receiving an abdominal surgical intervention between 1/22 and 4/24. The cohort included children receiving mapping +/- primary ileoanal pullthrough. An analysis of preoperative, perioperative, and postoperative data, and a short-term follow-up were performed. Results: A total of 18 children with TCA and no prior pullthrough received an abdominal intervention during the 29-month study period, and 5/18 (27.8%) were female. The children had a median of 4 (range 2-7) prior external surgeries; all had a stoma; 6 (33%) children received parental nutrition; 12 children underwent a mapping of the ganglia distribution and bowel length at a median age of 11 months (range 3-54), and in 10 of them, we relocated the stoma. There was a mean involvement of 15 (5-93) cm small bowel aganglionosis, with the remaining mean ganglionic small bowel having a length of 178 cm (110-254). A total of 11 children underwent straight primary ileoanal pullthrough of the stoma site at a median age of 16.7 months (10-133). Conclusions: The timely diagnosis of TCA still challenges the care team, and most children have a rough journey involving several surgeries until their diagnosis is established. The ensure bowel function with an adequate working stoma is the key to enabling enteral nutrition and growth, which are the baseline requirements to undertake a successful pullthrough procedure and restore continuity. Careful perioperative bowel management and parents' active involvement supports children with Hirschsprung Disease achieving the best possible quality of life.

Is the Transrectal Diameter (TRD) Suitable for Assessing Faecal Loads and Monitoring Bowel Management in Children with Hirschsprung Disease-ReKiSo Study: Prospective Study.

BACKGROUND: Constipation and outlet obstruction may persist after successful pull-through in Hirschsprung Disease (HD). The radiographic assessment of the faecal load is widely used but exposes the child to radiation. This study aims to evaluate whether the transrectal diameter (TRD) assessed with ultrasound correlates with symptoms of faecal load and whether the TRD normalises when symptoms disappear. METHOD: Children with HD after pullthrough and functional constipation presenting to our colorectal clinic between 4/23 and 4/24 were assessed for symptoms of constipation, smearing and outlet obstruction, as well as healthy controls. Ultrasound measurement of the TRD was conducted. Bowel management was initiated according to our institutional pathway using Peristeen© irrigation after an orthograde disimpaction regime. RESULTS: A total of 193 children underwent TRD assessment. Of 60 children with HD, 26 (43.3%) presented with obstructive symptoms, and 34 (56.7%) were asymptomatic. In asymptomatic patients with HD, the mean TRD of 2.26 cm (SD 0.61) was significantly (p < 0.001) lower than in HD with symptoms, with a mean TRD of 3.35 cm (SD 1.03). Individuals without colorectal pathology had a mean TRD of 2.04 cm (SD 0.37), and children with functional constipation and symptoms showed a mean TRD of 4.36 cm (SD 1.32). The mean TRD after symptom resolution was 2.37 cm. CONCLUSIONS: Children with HD without obstructive symptoms have a TRD < 3 cm, as do controls. The transrectal diameter allows the clinician to sonographically assess the faecal load in children with HD at the bedside without radiation. The TRD is useful for monitoring a bowel management program in children with HD.

Assessing fecal load with ultrasound in children with colorectal pathology: ReKiSo study.

PURPOSE: To evaluate bowel management for children with colorectal pathology by measuring transverse rectal diameter (TRD) and assessing fecal load with transabdominal rectal ultrasound (TRU). METHODS: Prospective case-control study of children receiving bowel management (BM) between 04/2023 and 04/2024 was done. There was inclusion of patients with Hirschsprung disease (HD), anorectal malformation (ARM) and functional constipation (FC). Patients with other congenital or neurological conditions were excluded. Control group consisted of inpatients and outpatients without abdominal complaints. FC was diagnosed according to ROM-IV-criteria. For HD and ARM, we followed a list of symptoms. To assess fecal load, we visualized the TRD using the Klijn (Klijn et al. in J Urol 172:1986-1988, 2004) method. The bladder was moderately full. The fecal load was assessed retrograde from the rectum. Follow-up was at 1/3/6 months. Secondary data were collected from medical records. Sample size calculated a priori and follow-up group with new gathered data. RESULTS: p value for TRD in all groups significant with p < 0.05 and in grouped follow-up. CONCLUSION: Ultrasound is a useful tool for assessing fecal load and helps diagnose constipation and monitor BM. Irrespective of colorectal pathology, a cut-off of 3 cm seems to discriminate between children without constipation/overload symptoms and asymptomatic patients. We present a radiation-free method for monitoring bowel management.

Bowel Management in Hirschsprung Disease-Pre-, Peri- and Postoperative Care for Primary Pull-Through.

(1) Background: Bowel management contributes throughout the pathway of care for children with Hirschsprung. Preoperative bowel management prepares the child and family for the pull-through surgery. Perioperative bowel management supports early recovery and tailored bowel management in the follow-up supports the achievement of social continence. (2) Methods: We conducted a cross-sectional assessment of our institutional bowel management program to illustrate the pre-, peri- and postoperative bowel management strategies. (3) Results: A total of 31 children underwent primary pull-through, 23 without a stoma and 8 with a stoma, at a median age of 9 months. All children without a stoma were prepared for surgery by using rectal irrigations. Children with a stoma were prepared for surgery with a transfer of stoma effluent. Transanal irrigation supported early recovery. (4) Conclusions: Bowel management is a key pillar of the management of children with Hirschsprung disease. Incorporating bowel management in the pathway of care facilitates primary pull-through and supports perioperative recovery.

Barriers and prospects for skin grafting in burn treatment across African countries.

INTRODUCTION: The current standard management of full-thickness or deep dermal burns is early tangential excision and skin grafting. A conservative approach to deep burns without the option of skin grafting results in delayed wound healing, possibly leading to wound infection and is associated with hypertrophic scarring and increased morbidity and mortality. The aim of this study was to improve the understanding of the management and availability to perform skin grafting for burns on the African continent. It also sought to identify challenges and perceived improvements. METHODS: A web-based, structured, closed-formatted, multinational survey was designed to gather information on the current state and availability of skin grafting of burn wounds on the African continent. The questionnaire consisted of 27 questions, available in English and French. It was reviewed within the GAP-Burn collaboration network and sent to 271 health care professionals who had participated in a previous study and had initially been recruited by means of the snowball system. RESULTS: The questionnaire was completed 84 times (response rate: 31.0%), of which 3 were excluded. Responses originated from 22 African countries. The majority 71 (87.7%) resulted from countries with a low Human Development Index (HDI), 7 (8.6%) from medium HDI countries. Split thickness skin grafting (STSG) is performed in 51 (63.0%) centers. The majority considers STSG to reduce length of stay (72.8%) and improve scarring (54.3%), yet some indicated that STSG is associated with increased risk of donor site infection (8.6%) and severe bleeding (7.4%). Factors preventing increased grafting included lack of equipment and training. CONCLUSION: Skin grafting is not performed in a significant number of hospitals treating burns. The majority of the staff believe that more skin grafting would lead to a better outcome. Advocacy and improved infrastructure, human resources coupled with introduction to well-structured health coverage for all in African countries could help to better access and affordability in burn care.

Point of Care Ultrasound in Pediatric Surgery across the European Region-European Pediatric Surgery Association Endorsed Survey.

INTRODUCTION: Our purpose was to assess the state of training, clinical practice, and barriers to use point-of-care ultrasound (POCUS) in pediatric surgery in Europe. METHODS: An electronic survey was disseminated among European pediatric surgeons utilizing the European Pediatric Surgery Association network and other existing networks. RESULTS: There were 186 respondents from 27 European countries and 7 non-European countries. In most countries (86.6%; N = 161), the initial ultrasound for acute admissions is performed by radiologists, with 1 to 6 hours turnover in 62.9% (N = 117) of urgent cases. Ultrasound by pediatric surgeons (point-of-care ultrasound/POCUS) is performed by 48.4% (N = 90) of respondents, with 29% (N = 54) using it at least once per week. The most common indications for POCUS include abdominal focused abdominal sonography in trauma (53.8%; N = 100), diagnosis of appendicitis (41.9%; N = 78), and intussusception (44.6%; N = 84). In malrotation-volvulus, 28.5% (N = 53) used ultrasound for its diagnosis, while 27.5% (N = 51) would not see an indication here. Training in POCUS occurred informally for 55.4% (N = 103) of participants, while 31.2% (N = 58) attended formal training courses. Almost all respondents wanted to attain further POCUS training (89.3%; N = 166), only 7% (N = 13) did not think this would be useful. For 73.1% (N = 136), POCUS is not currently part of the pediatric surgery training curriculum in their country. Perceived barriers to POCUS use include a lack of training opportunities (26.3% [N = 49]) and a paucity of portable ultrasound machines (17.8% [N = 33]). CONCLUSION: There is a wide spectrum of POCUS use in pediatric surgery across Europe. For those surgeons who practice POCUS, it is most used for the diagnosis of abdominal conditions. There are differing views among clinicians concerning the most useful applications of POCUS. The extent to which ultrasound is taught during pediatric surgery training differs substantially across European curricula.

State of burns management in Africa: Challenges and solutions.

INTRODUCTION: Understand the availability of human resources, infrastructure and medical equipment and perceived improvement helps to address interventions to improve burn care. METHODS: Online survey covering human resources, infrastructure, and medical equipment of burn centers as well as perceived challenges and points for improvement. The survey was distributed in English and French via snowball method. Descriptive statistics and AI-based technique random forest analysis was applied to identify determinants for a reduction of the reported mortality rate. RESULTS: 271 questionnaires from 237 cities in 40 African countries were analyzed. 222 (81.9 %) from countries with a very low Human Development Index (HDI) (4th quartile). The majority (154, 56.8 %) of all responses were from tertiary health care facilities. In only 18.8 % (n = 51) therapy was free of charge for the patients. The majority (n = 131, 48.3 %) had between 1 and 3 specialist doctors (n = 131, 48.3 %), 1 to 3 general doctors (n = 138, 50.9 %) and more than 4 nurses (n = 175, 64.6 %). A separate burn ward was available in 94 (34.7 %) centers. Regular skin grafting was performed in 165 (39.1 %) centers. Random forest-based analysis revealed a significant association between HDI (feature importance: 0.38) and mortality. The most important reason for poor outcome was perceived late presentation (212 institutions, 78.2 %). The greatest perceived potential for improvement was introduction of intensive care units (229 institutions, 84.5 %), and prevention or education (227 institutions, 83.7 %). INTERPRETATION: A variety of factors, including a low HDI, delayed hospital presentation e.g. due to prior care by non-physicians and lack of equipment seem to worsen the outcome. Introduction of an intensive care unit and communal education are perceived to be important steps in improving health care in burns.

Background: Based on 190,000 applications for asylum, Germany remains a top destination for refugees and asylum seekers in Europe. The updated recommendations are considered evidence-based and targeted guidelines for the diagnosis and prevention of infectious diseases in underage refugees and asylum seekers. Objective: The objective of these recommendations is to guide medical staff in the care of minor refugees, in particular to:1. assure early recognition and completion of incomplete vaccination status,2. diagnose and treat common infectious diseases,3. recognize and treat imported infectious diseases that are considered uncommon to the German healthcare system. Material and methods: The recommendations have been formally written to be published as AWMF S1 guidelines.This includes a representative expert panel appointed by several professional societies, and formal adoption of the recommendations by the board of directors of all societies concerned. Results: Recommendations are given for the medical evaluation of minor refugees, including medical history and physical examination. A blood count as well as screening for tuberculosis and hepatitis B should be offered to all minor refugees. In addition, screening for other infectious diseases like hepatitis C, HIV or schistosomiasis should be considered depending on age and country of origin. Vaccinations are recommended based on both age and country of origin. Conclusion: As thousands of minor refugees continue to seek shelter in Germany every year, professional health care with adequate financial support needs to be established to ensure an appropriate medical treatment of this particularly vulnerable population.

Infants Younger Than 90 Days Admitted for Late-Onset Sepsis Display a Reduced Abundance of Regulatory T Cells.

Objective: To provide epidemiological data of infants < 90 days of age with suspected late-onset sepsis (LOS) and evaluate distinct immunological specificities. We hypothesized that previously healthy infants < 3 months of age with sepsis have a yet undefined immunological predisposition; e.g. differences in lymphocyte subsets including regulatory T cells. Methods: We performed an exploratory, single center study between January 1st, 2019 and June 1st, 2021. Routine diagnostics included conventional culture (blood, cerebrospinal fluid, urine), PCR and inflammatory markers in infants < 90 days of age with suspected sepsis. We additionally analyzed lymphocyte subsets and CD4+ CD25+ forkhead box protein (FoxP3)+ Tregs at admission for sepsis workup as compared to age-matched controls. Results: A convenience sample cohort of n= 51 infants with sepsis workup was enrolled. Invasive bacterial infection (IBI) was diagnosed in 25 (49.0%) patients including two infants with a rhinovirus co-infection and viral infection in 14 (27.5%) neonates. No infectious cause was found in 12 cases. Infants with suspected LOS displayed a decreased abundance of CD4+ FoxP3+ T cells as compared to controls, which was most pronounced in the subgroup of infants with IBI. We also noticed elevated HLA-DR-positive CD3+ cells in infants with LOS and a higher CD4/CD8-ratio in infants with viral infection as compared to healthy controls. Infants with viral infections had a higher number of natural killer cells as compared to infants with IBI. Conclusion: Our exploratory data support the concept of a potential immaturity state and failed immune tolerance development for young infants with LOS. Future large-scale studies are needed to elucidate pre-sepsis conditions and to target the microbiome-immunity interplay as a potential risk pattern.

Optical coherence tomography provides an optical biopsy of burn wounds in children-a pilot study.

Thermic injuries are among the most severe injuries in childhood. Burn depth is the most relevant prognostic factor, and still its assessment is both difficult and controversial. This diagnostic uncertainty results in repeated wound assessments over a 10-day period and carries a relevant risk for over- and undertreatment. Precise wound assessment would thus be a significant step toward improved care. Optical coherence tomography (OCT) is a noninvasive laser-based technique with a penetration depth of ∼2 mm. It provides structural images of the skin while dynamic OCT (D-OCT) shows blood vessels. In this study, we investigated burns and scalds in 130 children with OCT and D-OCT to identify patterns of injury related to the depth of the burn wound. OCT and D-OCT images from burned skin differed consistently from normal skin. We observed several not formerly described morphologic patterns associated with burn injuries. Superficial wounds are characterized by a loss of the epidermal layer and a smooth surface. With deeper wounds, surface irregularity, loss of the dermal papillary pattern, disappearance of skin lines, and characteristic changes in the microvascular architecture were observed. This is the first systematic study of D-OCT in the assessment of burn wounds in children. A number of burn-associated patterns of injury were identified. Thus, D-OCT provided an "optical biopsy" of burn wounds that adds significant information about the severity of a burn wound.

Endoscopy and Laparoscopy in Disorders of Sex Development.

Endoscopy and laparoscopy are used for the assessment of disorders of sex development (DSD) and therapeutic interventions. Endoscopy (urethra-cystoscopy, vaginoscopy) is especially useful when vaginal or urethral surgery is planned. It is also valuable for the assessment of complications. Laparoscopy is used to identify sex ducts and gonads and to perform minimally invasive abdominal and pelvic surgery. This article reviews clinical indications, limitations, findings, and their reporting. It further discusses the impact of these findings on care in typical clinical situations.
