RESUMO
PURPOSE: It is unknown if failed preoperative vacuum bell (VB) treatment in patients undergoing minimally invasive repair of pectus excavatum (MIRPE), delays repair and/or affects postoperative outcomes. METHODS: A retrospective data analysis including all consecutive patients treated at one single institution undergoing MIRPE was performed between 2000 and 2016. Patients were stratified into preoperative VB therapy versus no previous VB therapy. RESULTS: In total, 127 patients were included. Twenty-seven (21.3%) patients had preoperative VB treatment for 17 months (median, IQR 8-34). All 27 patients stopped VB treatment due to the lack of treatment effect. Eight (47.1%) of 17 assessed VB patients showed signs of skin irritation or hematoma. VB treatment had no effect on length of hospital stay (p = 0.385), postoperative complications (p = 1.0), bar dislocations (p = 1.0), and duration of bar treatment (p = 0.174). Time spent in intensive care unit was shorter in patients with VB therapy (p = 0.007). Long-term perception of treatment including rating of primary operation (p = 0.113), pain during primary operation (p = 0.838), own perspective of look of chest (p = 0.545), satisfaction with the procedure (p = 0.409), and intention of doing surgery again (p = 1.0) were not different between groups. CONCLUSIONS: Failed preoperative VB therapy had no or minimal effect on short-term outcomes and long-term perceptions following MIRPE.

OBJECTIVES: To show the feasibility of magnetic double-J-stent (mDJS) removal without general anaesthesia in infants and children. METHODS: A retrospective analysis of mDJS removals was conducted between February 2018 and July 2020 in a cohort of 32 consecutive paediatric patients. Only patients with unilateral ureteric stenting were included. Stent retrieval was performed in an outpatient setting. In males the junction of the retrieval-catheter and the mDJS was confirmed by transabdominal ultrasound. All patients were followed-up for 4-12 weeks after stent removal. RESULTS: Thirty-two patients (54% males) were included. Median age was 3.8 years (range 1 month - 15 years). Ureteral stents remained in place for a median of 67.5 days (range 2 days - 6 months). General anaesthesia was necessary in one single patient due to expressed patient's and caregiver's wish. Thirty-one patients had stent removal without need for general anaesthesia. Thereof, nitrous oxide was used in 12 patients (37.5%), fentanyl in 3 patients (9.4%), midazolam in 3 patients (9.4%), and 17 patients (53.1%) did not need sedation at all. Seven patients (21.9%) being 8 months or younger had received peroral saccharosis. No complications occurred during stent removal. Retrieval was successful at first catheterization in 30 patients (93.8%). Two male patients needed a second catheterization (6.3%). CONCLUSION: The use of magnetic DJS is safe in the paediatric population and spares general anaesthesia during removal in almost all patients.

The expression of amino acid transporters in small intestine epithelia of human newborns has not been studied yet. It is further not known whether the maturation of imino acid (proline) transport is delayed as in the kidney proximal tubule. The possibility to obtain small intestinal tissue from patients undergoing surgery for jejunal or ileal atresia during their first days after birth was used to address these questions. As control, adult terminal ileum tissue was sampled during routine endoscopies. Gene expression of luminal imino and amino acid transporter SIT1 (SLC6A20) was approximately threefold lower in newborns versus adults. mRNA levels of all other luminal and basolateral amino acid transporters and accessory proteins tested were similar in newborn mucosa compared with adults. At the protein level, the major luminal neutral amino acid transporter B0AT1 (SLC6A19) and its accessory protein angiotensin-converting enzyme 2 were shown by immunofluorescence to be expressed similarly in newborns and in adults. SIT1 protein was not detectable in the small intestine of human newborns, in contrast to adults. The morphology of newborn intestinal mucosa proximal and distal to the obstruction was generally normal, but a decreased proliferation rate was visualized distally of the atresia by lower levels of the mitosis marker Ki-67. The mRNA level of the 13 tested amino acid transporters and accessory proteins was nonetheless similar, suggesting that the intestinal obstruction and interruption of amniotic fluid passage through the small intestinal lumen did not affect amino acid transporter expression. NEW & NOTEWORTHY System IMINO transporter SIT1 is not expressed in the small intestine of human newborns. This new finding resembles the situation in the proximal kidney tubule leading to iminoglycinuria. Lack of amniotic fluid passage in small intestinal atresia does not affect amino acid transporter expression distal to intestinal occlusion.

Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) and anorectal malformations (ARM) represent the severe ends of the fore- and hindgut malformation spectra. Previous research suggests that environmental factors are implicated in their etiology. These risk factors might indicate the influence of specific etiological mechanisms on distinct developmental processes (e.g. fore- vs. hindgut malformation). The present study compared environmental factors in patients with isolated EA/TEF, isolated ARM, and the combined phenotype during the periconceptional period and the first trimester of pregnancy in order to investigate the hypothesis that fore- and hindgut malformations involve differing environmental factors. Patients with isolated EA/TEF (n = 98), isolated ARM (n = 123), and the combined phenotype (n = 42) were included. Families were recruited within the context of two German multicenter studies of the genetic and environmental causes of EA/TEF (great consortium) and ARM (CURE-Net). Exposures of interest were ascertained using an epidemiological questionnaire. Chi-square, Fisher's exact, and Mann-Whitney U-tests were used to assess differences between the three phenotypes. Newborns with isolated EA/TEF and the combined phenotype had significantly lower birth weights than newborns with isolated ARM (P = 0.001 and P < 0.0001, respectively). Mothers of isolated EA/TEF consumed more alcohol periconceptional (80%) than mothers of isolated ARM or the combined phenotype (each 67%). Parental smoking (P = 0.003) and artificial reproductive techniques (P = 0.03) were associated with isolated ARM. Unexpectedly, maternal periconceptional multivitamin supplementation was most frequent among patients with the most severe form of disorder, i.e. the combined phenotype (19%). Significant differences in birth weight were apparent between the three phenotype groups. This might be attributable to the limited ability of EA/TEF fetuses to swallow amniotic fluid, thus depriving them of its nutritive properties. Furthermore, the present data suggest that fore- and hindgut malformations involve differing environmental factors. Maternal periconceptional multivitamin supplementation was highest among patients with the combined phenotype. This latter finding is contrary to expectation, and warrants further analysis in large prospective epidemiological studies.

The ARM-Net (anorectal malformation network) consortium held a consensus meeting in which the classification of ARM and preoperative workup were evaluated with the aim of improving monitoring of treatment and outcome. The Krickenbeck classification of ARM and preoperative workup suggested by Levitt and Peña, used as a template, were discussed, and a collaborative consensus was achieved. The Krickenbeck classification is appropriate in describing ARM for clinical use. The preoperative workup was slightly modified. In males with a visible fistula, no cross-table lateral X-ray is needed and an anoplasty or (mini-) posterior sagittal anorectoplasty can directly be performed. In females with a small vestibular fistula (Hegar size <5 mm), a primary repair or colostomy is recommended; the repair may be delayed if the fistula admits a Hegar size >5 mm, and in the meantime, gentle painless dilatations can be performed. In both male and female perineal fistula and either a low birth weight (<2,000 g) or severe associated congenital anomalies, prolonged preoperative painless dilatations might be indicated to decrease perioperative morbidity caused by general anesthesia. The Krickenbeck classification is appropriate in describing ARM for clinical use. Some minor modifications to the preoperative workup by Levitt and Peña have been introduced in order to refine terminology and establish a comprehensive preoperative workup.

BACKGROUND: Association between chronic airway diseases (CAD) and gastroesophageal reflux disease (GERD) is well described, but causality has not yet been conclusively established. This study evaluates the therapeutic significance of laparoscopic Thal fundoplication in children with CAD and diagnosed GERD. METHODS: We performed a retrospective analysis of 182 neurologically nonimpaired children, all with medically refractory CAD and GERD undergoing laparoscopic Thal fundoplication. The clinical response, ability to wean oral and inhaled medication and satisfaction with postoperative results were evaluated. RESULTS: Main symptoms disappeared completely in 68.7% of patients and were markedly improved in a further 22% of patients following surgery. Complete discontinuation of medication was achieved in 70.1-96.4% of cases and reduced in a further 1.8-23.5%. One intraoperative complication occurred (gastric perforation), however no conversion to laparotomy was necessary. Postoperative Dumping Syndrome occurred in 1% of cases and was managed dietetically. Prolonged postoperative dysphagia occurred in 4.3% of patients, but disappeared within 8 weeks in all but one case. CONCLUSIONS: Our study suggests that Thal fundoplication in neurologically nonimpaired children with CAD and documented GERD is effective and safe. Children unresponsive to preoperative medical management showed significant improvement in airway symptoms together with a marked reduction in the need for medication. We conclude that laparoscopic Thal fundoplication represents a significant treatment worthy of consideration in this group of patients.

BACKGROUND: Intracorporeal suturing and knot tying (ICKT) in minimal invasive surgery (MIS) represents a key skill for advanced procedures. Different methods exist for measuring knot quality and performance, but the heterogeneity of these methods makes direct comparisons difficult. The aim of this study is to compare the quality of a laparoscopic knot to one that is performed open. METHODS: To compare open and laparoscopic knot-tying methods we used a surgeon's square knot. For laparoscopic knot tying we used a Pelvitrainer. The 32 participants were divided among 4 groups of different skill levels. Group 1 consisted of 6 senior physicians. Group 2 was made up of 10 first to fourth year interns. Groups 3 and 4 contained 16 medical students who had never performed either laparoscopic procedures or open sutures before. Group 3 participants received a 1-hour hands-on training in suturing, whereas group 4 participants received no prior training. Total time, knot quality, suture placement accuracy, and performance defined the parameters for assessment in this study. RESULTS: All participants, irrespective of education level were inferior in ICKT compared to open suturing. Only Group 1 showed no significant difference in knot quality and accuracy between the open and laparoscopic suture performance. CONCLUSION: It is well documented that psychomotor skills need to be developed before more advanced skills can be put into practice. Training centres for minimally invasive surgery should be an integral part of surgical education. The variables in our study are meaningful and easy to implement. They can be used to measure personal progress and as objective parameters in the development of laparoscopic trainee education.

BACKGROUND: While enhanced recovery after surgery (ERAS) programs are the standard for perioperative management, special nutritional care has to be administered to malnourished patients and those at metabolic risk with special regard to patients with postoperative complications. METHODS: Existing guidelines of the German and European societies of nutritional medicine (DGEM and ESPEN) on enteral and parenteral nutrition in surgery were merged and in accordance with the principles of the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF, German Association of the Scientific Medical Societies) and Ärztliches Zentrum für Qualität in der Medizin (AeZQ, German Agency for Quality in Medicine) revised and extended. RESULTS AND DISCUSSION: The working group developed 41 consensus-based recommendations for perioperative nutrition. The recommendation strength is: 9x A (recommendation based on significant good quality literature containing at least one randomized controlled trial), 12x B (recommendation based on well-designed trial without randomization), 13x C (recommendation based on expert opinions and/or clinical experience of respected authorities) and 7x CCP (clinical consensus point). CONCLUSION: Even in patients without obvious malnutrition perioperative nutritional support is indicated when oral food intake is not feasible or inadequate for a longer period of time.

BACKGROUND: Short bowel syndrome (SBS) is still a life-threatening disease in both children and adults. Although the therapeutic options are improving, challenges still remain, and to overcome these challenges is a major focus of SBS research today. In order to simulate anatomical and physiological conditions similar to those in humans for research, porcine models of SBS are often used. Various approaches for generating SBS models have been described in the literature. METHODS/RESULTS: In this work, we present a review of different types of porcine models of SBS and outline the differences between those models regarding types of animals, surgical procedures, monitoring, and methods of assessment. CONCLUSION: The aim of this study was to select the most suitable SBS model regarding the purpose of the research.

BACKGROUND: In order to prevent stricture of the neoanus after surgical correction, regular dilatation is recommended. There is a lack of knowledge about the performance of anal dilatation and the occurrence of pain. The aim of our investigation was to describe the practice of dilatation and to identify possible risk factors for painful procedures. METHODS: Congenital Uro-Rectal Malformations Network is a German interdisciplinary multicenter research network. With standard questionnaires, physicians interviewed 243 patients and/or their parents at home, additional 103 patients born since 2009 were assessed through their treating physicians. RESULTS: In total, 88 % of the patients received dilatations. Treatment lasted for 7 months in median (range 1-156 months), until the age of 13 months (range 1-171 months). In 69 % painful dilatation was reported; without a significant differences in age or gender. In 32 % bleeding was reported. In 30 % at least one dilatation was performed under general anesthesia. In 11 % some kind of analgesia was used. Type of fistula, dilatations lasting longer than 10 months and Hegar size above 15 were relevant factors for experience of pain. There were about 16 % postoperative strictures of the neoanus, without reported differences in dilatation procedures; but there was a relation to type of malformation. CONCLUSION: Considering the high number of painful treatments, predictors for painful dilatations should be further clarified through standardized documentation and prospective evaluation in order to improve follow-up.

Traumatic dislocation of the elbow is rare in children with an incidence of 3-6% of all elbow injuries. In the literature the outcome after elbow dislocation in childhood is rarely discussed. In the present study 33 children treated in our clinic from 2001 to 2008 with an acute traumatic dislocation of the elbow were retrospectively included. All events were unilateral whereby 1 child (3%) showed a recurrence of elbow dislocation after 9 weeks, 30% had a pure dislocation, 70% had a concomitant fracture, 55% showed a fracture of the medial epicondyle, 6% a fracture of the lateral epicondyle and 9% a further fracture. Of the fractures 83% required open reduction with osteosynthesis. After an average of 4.5 years 20 children (61%) were clinically examined. There were no instabilities of the joint and only minor clinical limitations of the range of motion. The established Mayo elbow performance score showed good to excellent results for all children. Despite severe joint trauma with frequently accompanying fractures, post-traumatic functional deficits are rarely limiting, independent of the accompanying fracture. The frequency of recurrence is low and instabilities were not seen.

UNLABELLED: The mechanism of therapeutic success of propranolol for severe infantile haemangioma remains unclear. Propranolol was shown to modify matrix metalloproteinase (MMP) levels, which are associated with tumour pathogenesis. We hypothesized that urinary MMP2/9 is higher in patients with infantile haemangioma compared to healthy infants and that propranolol reduces MMP2/9 levels and thus leads to an involution of the haemangioma. In this case, MMP2/9 could be used as a marker of indicated therapy or therapeutic success. Urinary samples were taken before, 2 weeks after, and 2 months after the beginning of propranolol treatment in haemangioma patients and once in healthy controls. Activity of MMP2/9 was determined by commercially available activity kits. Urine of 22 haemangioma patients and 21 control subjects was obtained. Propranolol therapy had significant success in all patients. MMP2/9 was present in most samples, the younger the children the higher the MMP2 levels. Haemangioma patients showed lower levels of MMP2. The MMP2 levels were significantly higher after 2 weeks of propranolol than prior to therapy. There were no differences in MMP9 levels. CONCLUSIONS: Presence of MMP2/9 in the urine of infants <1 year can be explained by high rate of physiological tissue remodelling. Unexpectedly, MMP2 was lower in the urine of haemangioma patients and higher 2 weeks after propranolol treatment. Taking this and the diverse results in literature into account, the correlation between MMPs, proliferation, and regression of haemangiomas and propranolol remains unclear.

PURPOSE: Short bowel syndrome (SBS) is a malabsorption disorder of the intestine, which leads to an inadequate alimentary supply. A number of therapeutic approaches are already in use, but research advances may provide new options in the future. The purpose of this paper was to provide an overview of the established therapeutic approaches together with a discussion of the future perspectives in the treatment of patients with SBS. We review those studies dealing with the treatment of SBS patients and discuss both surgical and non-surgical approaches together with tissue engineering. METHODS: A systemic review of Medline-cited studies dealing with current practice and future perspectives in the treatment of short bowel in children was performed. RESULTS: Surgical approaches, non-surgical approaches, and tissue engineering which was used in the treatment of SBS were analyzed. Among the surgical approaches, the bowel lengthening procedures and small bowel transplantation are prevalent. Stimulants are most important concerning non-surgical approaches. Tissue engineering seems to be more experimental and was also evaluated. CONCLUSION: The treatment of SBS patients remains very complex. It is eminent to find the best therapeutic option for each patient and to individualize and modify the different possible types of applied techniques frequently.

INTRODUCTION: Neuroblastoma (NB) is one of the most common malignant tumors in infancy. The commonly used International Neuroblastoma Staging System is not suitable for determining the surgical risks. To address this, we aimed to evaluate the correlation between so-called image-defined risk factors (IDRFs) and the surgical risks in abdominal neuroblastoma. MATERIAL AND METHODS: We evaluated 60 cases who underwent surgical intervention and examined the pre-surgical radiological imaging to look for IDRFs and surgical complications in children with abdominal neuroblastoma. RESULTS: The MRI- and CT-scans showed a total of 122 IDRFs in 39 cases. Complete resection was carried out in 50%, partial excision in 32%, and biopsy in 18% of cases. Total resection was possible in 100% of cases with no IDRF. Where IDRFs were present, total resection was only possible in 26% of cases (p<0.0001). We found a highly significant, negative correlation between the number of IDRFs and the possibility of performing complete resection of NB (p<0.0001). 7 (11.6%) complications were detected, all in patients who showed at least one IDRF previously. CONCLUSION: Our findings indicate that IDRFs are useful indicators for predicting surgical risk and surgical outcome and thus should be taken into account when planning surgery.

BACKGROUND: 4 methods are used in pediatric laparoscopic surgery to close trocar wounds. While tissue adhesives or adhesive strips have been shown to produce fewer wound complications and a better cosmetic result compared to trans- or only subcutaneous sutures, the choice of technique is still often based on the surgeon's personal experience. Thus, the objective of this trial was to assess the impact of tissue adhesives (Dermabond™) compared to adhesive strips (Steri-Strip™) on potential complications of wound healing, wound pain, cosmetic outcome, and patient satisfaction after laparoscopic appendectomy in children. METHODS: 49 patients undergoing laparoscopic appendectomy were enrolled in this prospective randomized trial. In every patient, two 5-mm and one 10-mm port-site incision was closed either with Dermabond™ or Steri-Strip™ after placing subcuticular absorbable sutures (4-0 Vicryl™). Postoperative complications, pain, and patient satisfaction with scars were evaluated at follow-up on day 10 and day 90 after the operation using a questionnaire and a visual analogue scale (VAS). Photographs of scars taken on day 90 were evaluated on a VAS by 2 pediatric surgeons blinded to the closure method used. RESULTS: According to the surgeons' evaluation of the cosmetic outcome, a significant difference between the 2 groups with regard to the cosmetic score was found on day 90 of follow-up, favoring Steri-Strip™ wound closure (p < 0.05). On day 10 and 90 there were no statistical differences between the 2 methods as regards the result of patient evaluations (p > 0.05). Only one wound infection (4%) was observed in the Steri-Strip™ group (n = 25) on day 10. At follow-up on day 90 two patients (9.1%) in the Dermabond™ group and one (4.8%) in the Steri-strip™ group complained of wound pain (p = 0.52). CONCLUSIONS: Both tissue adhesives and adhesive strips are excellent "no needle" alternatives for the closure of laparoscopic port-site incisions in children. As regards cosmetic outcome, Steri-Strip™ wound closure seems to be the most suitable and is also the less expensive technique.

INTRODUCTION: Our studies of clipped intestinal non-perforating anastomosis (CINPA) of the small bowel in a rat model have demonstrated that all clips migrated from the outside to the inside of the small bowel during the healing process. The aim of this study was to describe how the clips migrate. MATERIAL AND METHODS: In male Sprague Dawley rats small bowel anastomoses were performed with single, non-perforating metal clips. Bowel specimens were obtained from the anastomosed region for histological examination. RESULTS: On the day of surgery all clips were situated in the serous membrane. On the first postoperative day, an intramural migration could be observed. By days 6, 8, and 10 no clip was found in the peritoneum. All egested clips were found either in the distal lumen of the bowel or in the solid feces. H&E staining of the anastomoses studies indicated that the bowel wall everts immediately after being cut and becomes more and more inverted during the first few days after being anastomosed. CONCLUSION: Our studies showed that the observed dynamic movement of the bowel wall determines the movement of clip migration from the serosal to the mucosal side of the small bowel. In pediatric surgery the observed clip migration would be an important precondition for employing clipped intestinal non-perforating anastomosis (CINPA) routinely. However, further studies are necessary before the technique can be applied in daily practice.
