Should Pediatric Surgical Oncologists Receive Training in Vascular Surgery ? A Practice Survey Report From the International Society of Paediatric Surgical Oncology (IPSO).

BACKGROUND: Is vascular training in paediatric surgical oncology considered desirable ? METHODS: A voluntary survey of work practice was undertaken with the surgeon membership of The International Society Of Paediatric Surgical Oncology (IPSO) using a structured designed questionnaire. RESULTS: A total of 149 IPSO surgeon members completed the survey. 57% (N = 84) of surgeons surveyed had no specific training in vascular surgery. 43% surgeons (N = 63) stated they had acquired some skills in residency training and/or with transplantation surgery. 65% (N = 96) of respondent surgeons stated that vascular surgical training must be incorporated into pediatric surgical oncology training and 27% (N = 40) agreed that it was considered desirable. 89% (N = 133) of surgeon respondents had encountered major vascular injury during work practice while operating on pediatric solid tumors. Vascular injury repairs were undertaken and attempted by pediatric surgeons though expert assistance of vascular surgeons proved crucially essential in many instances. Emergent operations included patch repairs, vessel ligation techniques and insertion of vascular graft prostheses. Interventional radiology services to arrest life-threatening hemorrhage were also reportedly utilized by respondents. CONCLUSION: Vascular injuries have significant potential for devastating patient outcomes including never event 'mortality'. The IPSO surgeon survey highlights that there are visible 'gaps' in skills training. Training to be a pediatric oncology surgeon must incorporate acquisition of skill sets proficiency in vascular surgery.

Outcomes Assessment of Hypospadias Repair.

INTRODUCTION: Hypospadias is a congenital malformation, which involves the displacement of the urethral orifice on the underside of the penis. The mainstay treatment of hypospadias is surgery. Currently, there is no literature broadly assessing hypospadias repair outcomes in the Kingdom of Bahrain. This study aims to provide descriptive data on cosmetic, functional, and surgical outcomes of hypospadias repair at a single medical institute in the Kingdom of Bahrain. METHOD: Data on patients who underwent hypospadias repair from January 2012 to December 2020 by a single surgeon were reviewed. Parents of patients were contacted via telephone for consent. All consenting participants returned for an outpatient assessment of functional and cosmetic outcomes using an original questionnaire and the Pediatric Penile Perception Score, respectively. All responses were recorded using a four-point Likert scale. Surgical outcomes were assessed by reviewing postoperative notes. All collected data were anonymized. The study was approved by the King Hamad University Hospital institutional review board. RESULTS: Of the 29 patients who underwent surgical repair for hypospadias, 15 patients consented to participate. The mean age of the study population was 2.466 (SD = 0.496). Both parent and physician cosmetic assessments had similar results with the majority of participants very satisfied with all cosmetic parameters. Physician assessment reported higher satisfaction compared to parents. There were no reported cases of poor satisfaction. In terms of functional outcomes, there were no reported cases of straining on initiation, and a smooth and continuous urinary stream was reported in 80%. Only four patients reported post-void dribbling. When assessing surgical outcomes, 53.30% had coronally located urethra with no cases of postoperative complications. More than half of our patients were discharged after one day. CONCLUSION: Our study noted overall high satisfaction in terms of surgical, cosmetic, and functional outcomes. Physicians reported better cosmetic outcomes when compared to parents. Further analysis with a larger sample size across various medical institutes will be required to better assess post-repair outcomes.

Benchmarking of medication incidents reporting and medication error rates in a JCI accredited university teaching hospital at a GCC country.

Introduction: The benchmarking for medication incidents rate is not regarded as a recognized key performance measure or indicator in national or international organizations. The absence of benchmarking the medication incidents results in the loss of a self-governing perception of how well we performed compared to other peers. Methodology and settings: This 600-bed tertiary, Joint Commission International (JCI) accredited hospital retrospective analysis looked at all medication management-related events from January-2018 to December-2021. The study design follows descriptive, cross-sectional, retrospective prevalence research. Results: The rate of medication incidents that resulted in harm declined from Q3-2019 to Q4-2021. A significant increase in Pharmacy interventions/clarifications was recorded. Additionally, a significant increase in incidents reported with no-harm coupled with a significant reduction in incidences of serious events from 2019 to 2020. Finally, no-harm events were significantly reduced from 2020 to 2021. Discussion: The Pharmacy's study analyzed every medication incident documented from 2019 to 2021. 99.7% of reported incidents were classified as no-harm (near misses). There was an exponential decrease from Q1-2020 to Q1-202. A significant increase in incidents fell in the category of (near misses) with no-harm and a significant reduction in serious events. Pharmacy interventions/clarifications saw a massive increase and impact from Q3-2018 to Q2-2019, compared to the same period in 2018. By preventing medical incidents, benchmarking, and analyzing incidents and the reporting system, the use of information technology could dramatically reduce the rate of drug incidents. Conclusion: This study found that benchmarking medication incidents is valuable, as it can help identify areas where improvements can be made, implement strategies to improve safety, and track progress over time. The benchmark was recommended to be below 100 incidents for every 10,000 prescriptions/orders processed, and for E-I categories, below one incident for every 10,000 prescriptions/orders processed. This will help develop a worldwide standard with an absolved culture with non-punitive consequences.

Retrospective review of patients with testicular torsion in a University Hospital in Bahrain.

Introduction: Testicular torsion is a surgical emergency that, with delayed treatment, may be associated with loss of the testis. It commonly presents with sudden onset testicular pain, vague lower abdominal pain, nausea, and vomiting. Management often requires emergent surgical scrotal exploration, detorsion, and fixation or removal of the affected testis. Materials and Methods: Retrospective review of all the patients in a hospital covering the Muharraq district in Bahrain presenting with testicular pain. Results: During the six-year period from 2015 to 2021, 48 patients with testicular torsion were managed, with a mean age of 18.4 (± 9.2) years. Most patients (54.7%) presented within 6 hours of the onset of symptoms. All 48 patients underwent a doppler ultrasound, which confirmed the presence of testicular torsion in 87.5% of patients, with a sensitivity of 87% and specificity of 98.5%. Fourteen patients had non-viable testis on surgical exploration, with an average age of 16.6 (± 6.8) years and took an average of 13 to 24 hours to present to the emergency department after the start of pain. Most patients underwent scrotal ultrasound 60 minutes from the presentation to the emergency department and surgical exploration within 120 to 179 minutes. The rate of testicular torsion in patients who underwent diagnostic ultrasound at 60 minutes or more from presentation was 40%, compared to an overall rate of 29%. All detected cases of testicular torsion, except for one case, underwent bilateral fixation of the testes. Of those patients who underwent contralateral fixation, none presented with contralateral torsion, supporting the recommendation of contralateral fixation. Conclusion: Patients underwent comprehensive assessment of their complaint and emergent surgical intervention, including an ultrasound that did not delay the surgical intervention. We agree that clinical judgment is the primary tool for assessment of patients with acute scrotum and an adjunct emergent ultrasound does not significantly cause delays. We concur with the current recommendations for contralateral fixation and prompt surgical management as the anatomical anomaly is present bilaterally.

The Accuracy of Point-of-Care Ultrasound (POCUS) in Acute Gallbladder Disease.

There is increasing recognition that point-of-care ultrasound (POCUS), performed by the clinician at the bedside, can be a natural extension of the clinical examination-the modern abdominal "stethoscope" and provides an opportunity to expedite the care pathway for patients with acute gallbladder disease. The primary aims of this study were to benchmark the accuracy of surgeon-performed POCUS in suspected acute gallbladder disease against standard radiology or pathology reports and to compare time to POCUS diagnosis with time to definitive imaging. This prospective single-arm observational cohort study was conducted in four hospitals in Ireland, Italy, and Portugal to assess the accuracy of POCUS against standard radiology in patients with suspected acute biliary disease (ClinicalTrials.govIdentifier: NCT02682368). The findings of surgeon-performed POCUS were compared with those on definitive imaging or surgery. Of 100 patients recruited, 89 were suitable for comparative analysis, comparing POCUS with radiological findings in 84 patients and with surgical/histological findings in five. The overall global accuracy of POCUS was 88.7% (95% CI, 80.3-94.4%), with a sensitivity of 94.7% (95% CI, 85.3-98.9%), a specificity of 78.1% (95% CI, 60.03-90.7%), a positive likelihood ratio (LR+) of 4.33 and negative likelihood ratio (LR) of 0.07. The mean time from POCUS to the final radiological report was 11.9 h (range 0.06-54.9). In five patients admitted directly to surgery, the mean time between POCUS and incision was 2.30 h (range 1.5-5), which was significantly shorter than the mean time to formal radiology report. Sixteen patients were discharged from the emergency department, of whom nine did not need follow-up. Our study is one of the very few to demonstrate a high concordance between surgeon-performed POCUS of patients without a priori radiologic diagnosis of gallstone disease and shows that the expedited diagnosis afforded by POCUS can be reliably leveraged to deliver earlier definitive care for patients with acute gallbladder pathology, as the general surgeon skilled in POCUS is uniquely positioned to integrate it into their bedside assessment.

Surgeon-Performed Point-of-Care Ultrasound in the Diagnosis of Acute Sigmoid Diverticulitis: A Pragmatic Prospective Multicenter Cohort Study.

Background and purpose Early diagnosis and risk stratification of sigmoid diverticulitis rely heavily on timely imaging. Computerized tomography (CT), the gold standard diagnostic test, may be delayed due to resource constraints or patient comorbidity. Point-of-care ultrasound (POCUS) has an established role in trauma evaluation, and could potentially diagnose and stage acute diverticulitis, thus shortening the time to definitive treatment.  Aims This study aimed to benchmark the accuracy of surgeon-performed POCUS against CT in diagnosing and staging acute diverticulitis. A secondary aim was to evaluate the duration between the POCUS and the confirmatory CT scan report. Patients and methods A pragmatic prospective multicenter cohort study (ClinicalTrials.gov Identifier: NCT02682368) was conducted. Surgeons performed point-of-care ultrasound as first-line imaging for suspected acute diverticulitis. POCUS diagnosis and radiologic Hinchey classification were compared to CT as the reference standard. Results Of 45 patients with suspected acute diverticulitis, POCUS classified 37 (82.2%) as uncomplicated diverticulitis, four (8.8%) as complicated diverticulitis, and four (8.8%) as other diagnoses. The POCUS-estimated modified radiologic Hinchey classification was largely concordant with CT staging with an accuracy of 88.8% (95% CI, 75.95-96.2%), a sensitivity of 100% (95% CI, 90.2- 100%) and a specificity of 44.4% (95% CI, 13.7-78.8%). The positive predictive value (PPV) was 87.8% and the negative predictive value (NPV) was 100%. There was moderate agreement between CT and POCUS, with a Cohen's kappa coefficient of 0.56. The mean delay between CT and POCUS was 9.14 hours (range 0.33 to 43.5). Conclusion We examined the role of POCUS in the management of acute diverticulitis and our findings suggest that it is a promising imaging modality with the potential to reduce radiation exposure and treatment delays. Adding a POCUS training module to the surgical curriculum could enhance diagnosis and expedite the management of acute diverticulitis.

Pulmonary Actinomycosis in Children: A Prompt Diagnosis Can Prevent Surgery.

Pulmonary actinomycosis is an extremely rare disease in children. The diagnosis is challenging as the clinical presentation and radiological investigations may be atypical. We report a case of a pulmonary lesion extending to the chest wall posing as a malignant lesion. Biopsy revealed colonies of Actinomyces. Antibiotic therapy resolved the mass. A rare diagnosis of pulmonary actinomycosis should be kept as a differential diagnosis of such a mass in children.

Anomalous branching of the middle meningeal artery from the basilar artery: a systematic review.

Background: Anomalous origin of the middle meningeal artery (MMA) from the basilar artery is a rare congenital neurological variant that has been detected in both children and adults with diagnoses ranging from intracranial haemorrhage to ependymoma. This review aims to investigate the anatomical course of an anomalous basilar-middle meningeal artery and its clinical presentation. Methods: A systematic search was performed in PubMed using the keywords (middle meningeal artery) and (basilar artery). Ninety-four papers were identified, of which seven were included. One paper was further identified through cross-referencing. Results: The average age of presentation was 43 years with a male predominance (7/9). In most cases, the MMA arose between the superior cerebellar artery and the anterior inferior cerebellar artery (8/9) (versus 1 case between the anterior inferior cerebellar artery and the posterior inferior cerebellar artery). The anomaly mostly presented on the left side (6/11), but was bilateral in one case. Most of the cases showed a pontine artery branching from the basilar artery arising 5 mm to 10 mm proximal to the superior cerebellar artery, which would then assume the trajectory of the MMA. In three cases, the vessel increased in calibre near the trigeminal ganglion. Foramen spinosum absence in the anomalous side was noted in 3/6 of the patients. Conclusion: To avoid unexpected complications during neurosurgical and neuroradiointerventional procedures, it is essential to have a clear understanding of the anomalous routes of the MMA. This is especially important when it proves to be the only available route for embolization.

The role of registered charities in the delivery of global surgery in low- and middle-income countries - a personal experience.

The world's resources are unequally divided. Investment in healthcare in Low- and Middle-Income Countries (LMICs) has traditionally involved vertical public health strategies with little emphasis on the delivery of safe and effective surgery and anesthesia. The past 20 years has witnessed greater awareness of the numbers of people who have no access to surgery, the morbidity and mortality of such limited access, and the cost to the individual and society if a solution is not found. Global surgery has become a hot topic and The Millennium Development Goals (MDG) and the Sustainable Development Goals (SDG) have underlined the importance of surgery in national health care plans. The harsh metrics reported by the Lancet Commission has framed the problem in more concrete terms and as of today, over 5 billion people lack access to safe surgery, over 143 million extra surgeries are needed annually to affect the imbalance and more than 15,000 children die each day in Sub Saharan Africa and Southeast Asia from preventable disease, including the lack of access to safe surgery. Horizontal integrated healthcare that includes surgical provision is the new norm, but its introduction is expensive and will need time. The ambition of universal healthcare access for all people (SDG) with a corresponding reduction in child and maternal mortality will be difficult for most governments. Altruistic, Non-Governmental Organizations (NGOs) are ideally placed to assist this goal but must introduce changes in practice to include onsite and off-site training, broad partnerships with other NGOs and academic bodies and greater advocacy with governments to ensure sustainability. NGOs should work in concert with local agencies, hospitals and governments to meet local needs.

A novel technique for NGT fixation: Secure, simple, and safe.

Nasogastric tubes are often vitally important in post-operative management. Usually required for short term use, they are easily taped to the nose and face. Occasionally, longer term use is needed, such as in post esophageal reconstruction, where substitution and fixation of the NGT becomes an issue. We describe a novel method of NGT fixation that can be used for prolonged periods of time with minimal risk of dislodgement and without the need for suturing. INTRODUCTION: Nasogastric tubes (NGT) are a common practice in many clinical scenarios, and an easy and available method that is often essential for the prevention of life-threatening adverse complications such as aspiration pneumonia [1]. A common challenge arises in securing the NGT in place. Here, we describe a simple method to securely anchor an NGT tube for a prolonged period without the need to suture. METHOD: Steps of tube Fixation: 1. Distance between xiphisternum and mastoid process is measured and marked [Position A, Fig. 1]. This mark will correspond to the portion of the tube in the pharynx once the NGT is inserted. 2. A silk suture is tied to the NGT at the point marking the pharynx [Position A]. The two loose ends are not cut. 3. The NGT is inserted routinely through the nose. 4. Through the mouth, the NGT (and marked suture) is visualized using a laryngoscope. 5. Using a Magill forceps, the loose ends of the suture are pulled through the mouth. 6. The two loose ends are fed through a sleeve (small size feeding tube, cut to size) as to not cause irritation to the lips or the mucosa of the mouth and palate. 7. The two ends of the suture are tied around the nasal end of the NGT [Position B, Fig. 1] This method effectively creates a mini- "A-shaped"- double loop around the nasopharynx without interrupting the patency of the NGT, securing the tube safely without risk of dislodgement [Fig. 1]. It is of note that when marking the pharyngeal level on the NGT prior to insertion, it should be done with an overestimation of the distance by about 1,2 cm as the tube will be minimally pulled out after securing it using the method we described. (Fig. 1) DISCUSSION: Commonly used method of NGT fixation includes the triangular/Butterfly taping of the NGT to the tip of the nose. This can be challenging in patients with facial burns, facial hair, or simply uncooperative patients, where prolonged restraining is not a feasible option. Stitching of the NGT to the face or cheek has also been used in practice, but this could raise many complications including bleeding, or facial scarring [2]. With the method we described above, the NGT can be safely and easily secured in place without anchoring material on the face. It also negates the need for stitching. Additionally, it can be done with readily available tools and materials, without the need for high levels of training. While possible without sedation or anesthesia, this technique is best performed at the primary operation while the patient is under general anesthesia. CONCLUSION: This method of Nasogastric Tube fixation is a safe and secure method to maintain the long-term positioning of an NGT. When using this method, we did not note any dislodgement, minimal mucosal and lip irritation, and only minimal patient discomfort. It obviates the need for suture fixation.

Epidemiology of pediatric trauma in the Kingdom of Bahrain: a national pediatric trauma registry pilot study.

BACKGROUND: A pediatric trauma registry for the Kingdom of Bahrain would be a novel public health tool for the Bahraini health system. The aim of this study was to explore the epidemiology of pediatric trauma at the national level by describing the distribution of pediatric injury in the Kingdom, and quantifying the burden of injury shouldered by the study population. METHODS: This multicenter observational cross-sectional study was conducted in Bahrain using data from the Pediatric Trauma Registry (PTR), which was a short-term paper-based prospective trauma registry that collected data over a three-month period in 2018. PTR was based in the pediatric emergency departments (ED) of the three national referral hospitals in the Kingdom. By simultaneously collecting data from all three trauma hospitals in the country, it was assumed that during the data collection period all major pediatric trauma patients in the country would be captured by the study, and that the data collected would provide national estimates of trauma. Inclusion criteria for the study was any individual under the age of 14, that arrived at the ED seeking care for intentional and unintentional injuries. RESULTS: A total of 1328 patients were included in the study. Sixty-nine percent of patients were treated and discharged from the ED, 30.5% were admitted to the hospital, admitted for surgery, or seen by a specialist, and 0.5% were declared deceased. The percentage of patients documented as unrestrained during Motor Vehicle Collisions (MVC) was 92.3%, and amongst those involved in MVC, 12% were ejected from the cabin of the vehicle. CONCLUSIONS: There are significant implications that this study holds for policy implementation and practice surrounding injury prevention in the Kingdom of Bahrain. Low seatbelt utilization and the high proportion of ejection amongst MVC victims warrant immediate public health policy implementation, including enforcement of seat belt laws, strengthening of the traffic court system, and awareness campaigns for MVC prevention. Additionally, pediatric drowning prevention programs centered on constant adult supervision, pool isolation fencing, personal flotation devices, and swimming education should be created to address the mortality attributable to drowning in this study.

Smartphone Usage Among Doctors in the Clinical Setting in Two Culturally Distinct Countries: Cross-sectional Comparative Study.

BACKGROUND: Smartphones and mobile applications have seen a surge in popularity in recent years, a pattern that has also been reflected in the health care system. Despite increased reliance among clinicians however, limited research has been conducted on the uptake and impact of smartphone usage in medical practice, especially outside the Western world. OBJECTIVE: This study aimed to identify the usage of smartphones and medical apps by doctors in the clinical setting in 2 culturally distinct countries: King Hamad University Hospital (KHUH), Bahrain and Queen Mary Hospital (QMH), Hong Kong. METHODS: A cross-sectional, comparative study was conducted where doctors in both hospitals were asked to take part in a 15-item online survey. The questions were categorized into the following groups: demographics of the study population, ownership and main use of smartphones, number and names of medical apps currently owned, rating usage of smartphones for medical purposes, time spent on a smartphone related to clinical use, clinical reliance on smartphones, and views on further integration of smartphones. The results were then tabulated and analyzed using SPSS Statistics 25 for Mac (IBM Corp Inc, Armonk, NY). RESULTS: A total of 200 doctors were surveyed, with a total of 99.0% (99/100) of the doctors owning a smartphone in both KHUH and QMH; 58% (57/99) and 55% (54/99) of the doctors from KHUH and QMH, respectively, identified communication as their main use of smartphones in the clinical setting (P=.004). Doctors from KHUH were likely to spend more time on medical apps than doctors from QMH (P=.002). According to the overall results of both hospitals, 48% (32/67) of the junior doctors claimed high reliance on smartphones, whereas only 32.3% (41/127) of the senior doctors said the same (P=.03). Of doctors in KHUH and QMH, 78.0% (78/100) and 69.0% (69/100), respectively, either strongly agreed or agreed that smartphones need to be integrated into the clinical setting. In terms of preferences for future apps, 48% (48/100) and 56% (56/100) of the doctors in KHUH and QMH, respectively, agreed that more medical applications need to be created in order to support smartphone use in the clinical setting. CONCLUSIONS: These results suggest a substantial acceptance of smartphones by doctors in the clinical setting. It also elicits the need to establish policies to officially integrate smartphone technology into health care in accordance with ethical guidelines. More emphasis should be placed on creating medical applications that aid health care professionals in attaining their information from accurate sources and also regulate a system to monitor the usage of mobile devices within hospitals to prevent a breach of patient privacy and confidentiality.

Can we improve patient safety?

Despite greater awareness of patient safety issues especially in the operating room and the widespread implementation of surgical time out World Health Organization (WHO), errors, especially wrong site surgery, continue. Most such errors are due to lapses in communication where decision makers fail to consult or confirm operative findings but worryingly where parental concerns over the planned procedure are ignored or not followed through. The WHO Surgical Pause/Time Out aims to capture these errors and prevent them, but the combination of human error and complex hospital environments can overwhelm even robust safety structures and simple common sense. Parents are the ultimate repository of information on their child's condition and planned surgery but are traditionally excluded from the process of Surgical Pause and Time Out, perhaps to avoid additional stress. In addition, surgeons, like pilots, are subject to the phenomenon of "plan-continue-fail" with potentially disastrous outcomes. If we wish to improve patient safety during surgery and avoid wrong site errors then we must include parents in the Surgical Pause/Time Out. A recent pilot study has shown that neither staff nor parents found it added to their stress, but, moreover, 100% of parents considered that it should be a mandatory component of the Surgical Pause nor does it add to the stress of surgery. Surgeons should be required to confirm that the planned procedure is in keeping with the operative findings especially in extirpative surgery and this "step back" should be incorporated into the standard Surgical Pause. It is clear that we must improve patient safety further and these simple measures should add to that potential.

Parental involvement in the preoperative surgical safety checklist is welcomed by both parents and staff.

We involved the parents of paediatric patients in the first part of the three-stage WHO Surgical Safety Checklist (SSC) process. Forty-two parents took part in the study. They came to the theatre suite with their child and into the induction room. Immediately before induction of anaesthesia they were present at, and took part in, the first stage of the three-stage SSC process, confirming with staff the identity of their child, the procedure to be performed, the operating site, and the consent being adequately obtained and recorded. We asked parents and theatre staff later whether they thought that parental involvement in the SSC was beneficial to patient safety. Both parents and staff welcomed parental involvement in the WHO Surgical Safety Checklist and felt that it improved patient safety.

The use of the trapdoor incision for access to thoracic inlet pathology in children.

Lesions at the thoracic inlet are difficult to access via a thoracic or cervical approach. The use of the anterior cervico-thoracic trapdoor incision has been reported to give good exposure to the anterior superior mediastinum in adults. We report our experience of four cases where a trapdoor incision was used to gain excellent access and exposure to thoracic inlet pathology in children.

Esophageal strictures during treatment for acute lymphoblastic leukemia.

Esophageal stricture is a rare complication of paediatric cancer treatment that usually occurs after esophageal exposure to radiotherapy. We describe 4 cases of esophageal stricture during chemotherapy for acute lymphoblastic leukemia. All patients presented with refractory vomiting and were diagnosed with radiologic contrast studies. None of the patients had received radiotherapy. Esophageal candidiasis was seen in 2 patients but the remaining 2 patients had earlier systemic candidiasis. High-dose dexamethasone may predispose these children to both esophageal candidiasis and peptic esophagitis. The etiology of esophageal strictures during treatment for acute leukemia is likely to be multifactorial but systemic candidiasis may play a significant role.

Prenatal findings and neonatal immature gastric teratoma.

Immature teratoma of the stomach in the neonate is extremely rare.1(,)2 This report outlines a case of giant immature teratoma of the stomach, which was detected by prenatal ultrasonography in the third trimester as an echogenic mass contiguous with the stomach bubble. It increased from 4.5 cm in diameter to 7 cm between 34 and 37 weeks gestation. The baby was delivered by elective caesarean section at 37 weeks gestation. Neonatal imaging highlighted a differential diagnosis of nephroblastoma, neuroblastoma, pancreatoblastoma and teratoma. The infant underwent surgical excision of the abdominal mass on the 10th day of life. Histology revealed grade III immature gastric teratoma arising from the posterior wall of stomach, outlining the unknown implications of such a designation in an extraovarian site. The infant made a good postoperative recovery and is currently well 9 months later, without adjuvant therapy, and with no evidence of recurrent disease.

Experience with aortic grafting during excision of large abdominal neuroblastomas in children.

BACKGROUND: Total or near total resection of high-risk, stage 4 abdominal neuroblastoma has been correlated with improved local control and overall survival but may be complicated by vascular injury. We describe our experience in the management of significant aortic injuries during this procedure. METHODS: With the institutional review board waiver, medical records of children who had major abdominal aortic reconstruction during neuroblastoma resection from 1996 to 2006 were retrospectively reviewed. RESULTS: There were 5 children with aortic grafting: 3 girls and 2 boys. Mean age at surgery was 7.2 years (range, 16 months to 17 years). Two children were operated on for recurrent retroperitoneal disease. Tumor encasement of the aorta was seen in all children. In 3 children, the injury occurred during dissection of paraaortic and interaortocaval lymph nodes below the level of the renal arteries. In the remaining 2 children, injury occurred early during mobilization of the tumor. Three polytetrafluoroethylene tube grafts and 1 on-lay patch graft were used to repair the 4 distal aortic injuries. One 4-year-old female with aortic and renal arterial injuries was managed with an aortic Dacron tube graft and a polytetrafluoroethylene tube graft for the renal artery. The mean period of follow-up is 28 months after aortic graft (range, 3 months to 10 years). Total colonic ischaemia, transient acute tubular necrosis, and duodenal perforation were seen in one child, who needed subtotal colectomy and ileostomy. Another child with an omental patch over the graft had a transient duodenal obstruction, which was managed conservatively. There were no other complications, and 4 of the 5 children are disease-free to date. One child at 10 years after his distal aortic tube graft remained asymptomatic with normal distal blood flow on magnetic resonance angiogram and with normal growth. CONCLUSION: The neuroblastoma surgeon should be prepared to perform aortic and vascular reconstruction. Aortic encasement, preoperative radiation therapy, and reoperative surgery were observed in these patients and may be risk factors.

Transhepatic central venous catheter for long-term access in paediatric patients.

Vascular access in paediatric patients with chronic and/or life-threatening illness is crucial to survival. Access is frequently lost in this group because of thrombosis, infection, or displacement, and vascular options can quickly be exhausted. The last resort access procedure is generally a direct atrial catheter inserted via a thoracotomy. A viable alternative is the percutaneous transhepatic Broviac catheter (Bard Access Systems, Salt Lake City, UT). We retrospectively reviewed the charts of 5 patients who underwent percutaneous transhepatic Broviac insertion for long-term access over a 4-year period in a single institution. Four of the patients (80%) had a significant cardiac abnormality, with 1 patient requiring long-term parenteral nutrition after complicated necrotizing enterocolitis. All patients had significant caval thrombosis, which precluded them having placement of a standard percutaneous or openly placed central catheter. Of the 5 patients, 2 (40%) died of cardiac-related illnesses. Of the 3 surviving patients, 2 had functioning catheters electively removed because they were no longer required. One catheter was removed at thoracotomy for right atrial perforation because of catheter erosion. Vascular access in paediatric patients with chronic and/or life-threatening illness is crucial to survival. Transhepatic central venous catheters are a feasible, reliable, and relatively easily placed form of central access in patients with multiple venous thromboses requiring long-term access. This route should be considered in paediatric patients requiring central access in preference to a thoracotomy.
