Background and Objectives: Appendiceal carcinoids are rare neuroendocrine tumors and mainly found incidentally during histopathological examination following appendectomy. This observational cohort study was performed to determine the prevalence, treatment modalities and outcomes in children diagnosed with an appendiceal carcinoid tumor. Materials and Methods: Data from the largest German statutory health insurance "Techniker Krankenkasse" were analyzed within an 8-year period: January 2010 to December 2012 and January 2016 to December 2020. Patient characteristics, surgical technique, type of surgical department, diagnostic management, and postoperative morbidity were analyzed. Results: Out of 40.499 patients following appendectomy, appendiceal carcinoids were found in 44 children, resulting in a prevalence of 0.11%. Mean age at appendectomy was 14.7 (±2.6) years. Laparoscopic approach was performed in 40 (91%) cases. Right-sided hemicolectomy was performed in 8 (18%) patients. Additional diagnostic work-up (CT and MRI) was recorded in 5 (11%) children. Conclusions: This large nationwide pediatric study shows that 1 in 1000 patients was found to have a neuroendocrine tumor of the appendix (prevalence 0.11%), emphasizing its low prevalence in the pediatric age group. The majority of patients were treated with appendectomy only. However, treatment modalities are still variable. Longer follow-up analyses are needed to evaluate published guidelines and recommendations to aim for a limited surgical approach. [ABSTRACT FROM AUTHOR]

Introduction:  The pros and cons of video-assisted thoracoscopic versus conventional thoracic surgery in infants and children are still under debate. We assessed reported advantages and disadvantages of video-assisted thoracoscopy in pediatric surgical procedures, as well as the evidence level of the available data.Materials and Methods:  A systematic literature search was performed to identify manuscripts comparing video-assisted thoracoscopic and the respective conventional thoracic approach in classic operative indications of pediatric surgery. Outcome parameters were analyzed and graded for level of evidence (according to the Oxford Centre of Evidence-Based Medicine).Results:  A total of 48 comparative studies reporting on 12,709 patients, 11 meta-analyses, and one pilot randomized controlled trial including 20 patients were identified. More than 15 different types of advantages for video-assisted thoracoscopic surgery were described, mostly with a level of evidence 3b or 3a. Most frequently video-assisted thoracoscopic surgery was associated with shorter hospital stay, shorter postoperative ventilation, and shorter time to chest drain removal. Mortality rate and severe complications did not differ between thoracoscopic and conventional thoracic pediatric surgery, except for congenital diaphragmatic hernia repair with a lower mortality and higher recurrence rate after thoracoscopic repair. The most frequently reported disadvantage for video-assisted thoracoscopic surgery was longer operative time.Conclusion:  The available data point toward improved recovery in pediatric video-assisted thoracoscopic surgery despite longer operative times. Further randomized controlled trials are needed to justify the widespread use of video assisted thoracoscopy in pediatric surgery. [ABSTRACT FROM AUTHOR]

Introduction:  We aimed to identify clinical factors affecting condition-specific health related quality of life (HRQOL) domains in children born with esophageal atresia (EA). This can facilitate preventive care to risk groups of HRQOL impairments.Materials and Methods:  A total of 124 Swedish and German families of EA children answered the validated EA-QOL questionnaires (response rate 68%), for evaluation of three HRQOL domains in children 2 to 7 years old (53 parents) and four HRQOL domains in children 8 to 17 years old (62 children/71 parents). Clinical data were collected through medical records and a questionnaire. Statistics included between-group analysis, univariable and stepwise multivariable regression analysis, p < 0.05.Results:  Between 2 to 7 years, no primary anastomosis (p = 0.022) and female gender (p = 0.026) predicted worse scores related to "physical health and treatment," and gastrostomy insertion related to "eating" (p = 0.0001), and "social isolation and stress" (p = 0.001). Between 8 to 17 years, no primary anastomosis (child report), prematurity, esophageal dilatation (parent report) predicted poor HRQOL related to "eating" (p < 0.05), associated anomalies to "body perception" (p = 0.031, parent report), female gender (p = 0.018, child report) and severe EA (p = 0.011 child report, p = 0.004 parent report) to "social relationships," and severe EA predicted worse "health and well-being" scores (p = 0.004, parent report). An increased number of digestive symptoms (difficulty swallowing food, heartburn, and vomiting), lowered all EA-QOL domain scores in both age groups (p < 0.001). An increased number of respiratory problems (cough, wheezing, airway infections. breathlessness, and chest tightness), lowered scores in two HRQOL domains among children 2 to 7 years (p < 0.05).Conclusion:  Impairments within condition-specific HRQOL domains in EA children are found in congenital and surgical subgroups, and notably related to digestive symptoms throughout childhood.

Introduction:  For parents of chronically ill children, the experiences of caregiving are challenged by increased demands and restrictions imposed by their child's disease. Therefore, this study aims to investigate the quality of life (QoL) in parents of children born with esophageal atresia (EA) and to explore associated factors.Materials and Methods:  Parents of children (2-17 years) with EA recruited from two German pediatric hospitals participated in this cross-sectional study about QoL in EA. Data on QoL, sociodemographic, and clinical characteristics were collected from parents and children. Parental QoL was assessed using the Short-Form 8 questionnaire, containing eight dimensions aggregated to a mental and physical health summary score which was compared with German representative population norms.Results:  Forty-nine families (47 mothers and 40 fathers) participated in the study. Compared with German population norms, both mothers and fathers showed significantly lower mental component score (MCS) but no differences in physical component score (PCS). Within the study sample, parents of younger children (2-7 years), severe EA, or high school/kindergarten absence had lower MCSs compared with those with older, less severe, and less absent children. Parental female gender was associated with lower MCS as well as lower family income.Conclusion:  Parents of children with EA reported lower mental health compared with the general population, especially mothers, and parents of young children, with severe EA, and a frequent school/kindergarten absence. This shows that parents may experience substantial emotional burden and highlights the need for psychosocial support for EA parents, especially in the first years. [ABSTRACT FROM AUTHOR]

Abstract: Background: Health-related quality of life (HRQoL) after esophageal atresia (EA) repair is postulated to be good. However, little is known about the long-term results after repair of complex and/or complicated EA regarding HRQoL. We investigated long-term HRQoL after delayed anastomosis, esophageal replacement, major revisions, or multiple dilatations in patients registered in a support group. Methods: Patients registered in the German patient support group database (KEKS) were enrolled and allocated to subgroups according to surgical treatment and age. HRQoL was evaluated using validated questionnaires (GIQLI, WHO-5, KIDSCREEN27). Results: Complete follow-up (mean 14.5±9.8years) was available for 90/92 patients. Patients were allocated to subgroups delayed anastomosis (n=28), esophageal replacement (n=27), major revisions (n=15), and multiple dilatations (n=20). Adult patients presented with impaired well-being according to WHO-score and gastrointestinal function (GIQLI). In contrast, HRQoL of children was comparable to controls in most KIDSCREEN27-dimensions. Delayed anastomosis was associated with most-favourable HRQoL. Regarding physical well-being, these children scored significantly better than controls [64.01±10.40 vs. 52.36±8.73;p=0.0011], children after replacement [51.40±5.70;p=0.008], revisions [52.04±6.97;p=0.026], and multiple dilatations [50.22±9.67,p=0.04]. Conclusions: HRQoL after complex and/or complicated EA is excellent in children registered in a patient support group. In adults, disease-specific symptoms negatively affect HRQoL. Our data indicate that saving the esophagus may achieve the best HRQoL. [Copyright &y& Elsevier]

Introduction Laparoscopic techniques have evolved quickly in recent years and are regarded as standard procedures in pediatric surgery today. However, most studies comparing laparoscopic operations with the corresponding open procedure do not reach a high level of evidence according to the criteria of the Oxford Centre for Evidence- Based Medicine. For evidence Level 1a, a meta-analysis (MA) of different randomized controlled trials (RCTs) is required. For evidence Level 1b, at least one RCT is required. The aim of our study was to evaluate the availability of Level 1 studies comparing laparoscopic procedures with the corresponding open operation in pediatric surgery. Materials and Methods Systematic review of clinical Level 1 studies using PubMed. All MA and RCT were identified and individually reviewed. Only studies comparing pediatric laparoscopic procedures with the corresponding open operation were included. RCTs included in MA were only individually analyzed if they focused on additional endpoints. Endpoints of the study were advantages and disadvantages of laparoscopy compared with the open operation. Results A total of 20manuscriptsmet the inclusion criteria (9 MA and 11 RCT). Studies providing evidence Level 1a were identified for five types of laparoscopic procedures (laparoscopic appendectomy, inguinal hernia repair, orchidopexy, pyloromyotomy, and varicocelectomy). Studies providing evidence Level 1b were identified for two types of laparoscopic procedures (fundoplication and pyeloplasty). The advantages of laparoscopy were less wound infections, ileus and postoperative pain (appendectomy), less retching (fundoplication), lower incidence of metachronous inguinal hernia, shorter hospital stay (appendectomy, orchiopexy, and pyeloplasty), and shorter time to full feeds (pyloromyotomy). Conclusion Studies providing evidence Level 1 are only available for seven laparoscopic procedures in pediatric surgery. Effort has to be made to extend the existing Level 1 evidence and to gain high level evidence for further laparoscopic procedures. [ABSTRACT FROM AUTHOR]

Summary: Background: Vascular clamping techniques are commonly used but so far the impact on pediatric liver surgery has not been investigated. The purpose of this study was to analyze pedicle clamping during pediatric liver resection in terms of hepato-cellular injury and blood loss. Methods: Sixty-seven children undergoing liver resection were analyzed retrospectively. Vascular clamping was used in 28 cases (PC group), in 39 the resection was performed without clamping (NPC group). Major hepatectomies (resection of more than three segments) were carried out in 88%, minor hepatectomies (resection of three and less segments) in 12% of patients. Twenty-six children underwent extended liver resection. Patient data, liver function tests (LFTs) and blood loss were analyzed statistically. Results: There were no significant differences in patient preoperative and postoperative data and LFTs between the groups. Within the NPC group the amount of administered fresh frozen plasma (FFP) in total and per kilogram (FFP/kg) was significantly higher (p=0.023 and 0.028) than in the PC group. For patients with extended liver resection, operation times were significantly longer (p=0.016) in the group without vascular clamping (NPCext). In the NPCext group significantly more children required packed red cells, FFP and FFP/kg. LFTs showed no significant differences in all children regardless of vascular clamping. Conclusions: For children undergoing liver resection, vascular clamping offers a blood saving surgical technique. Postoperative LFTs were not statistically different, regardless of vascular clamping. Pedicle clamping proved to be a safe method, not associated with an increase in perioperative complications. [Copyright &y& Elsevier]
