- OBJECTIVE: The aims were to evaluate the outcome and to identify predictors for survival and enteral autonomy in neonatal intestinal failure (IF).METHODS: A retrospective observational study in a Swedish tertiary centre of children born between 1995 and 2016 with neonatal IF, defined as dependency on parenteral nutrition (PN) ≥60 days, starting with PN before the age of 44 gestational weeks. Data were extracted from medical records and predictors for survival and enteral autonomy were identified by the Cox regression model. Time to death and weaning off PN analysis were performed with Kaplan-Meier curves including log rank test.RESULTS: In total, 105 children were included. Median gestational age was 28 weeks (22-42), 50% were born extremely preterm (<28 gestational weeks). PN started at a median age of two days (0-147) with a median duration of 196 days (60-3091). Necrotising enterocolitis was the dominating cause of IF (61%). Overall survival was 88%, five children died of sepsis and four of intestinal failure-associated liver disease. Survival increased from 75% during 1995-2008 to 96% during 2009-2016 (p = 0.0040). Age-adjusted small bowel length of >50% and birth 2009-2016 were predictors for survival. Enteral autonomy was achieved in 87%, with positive prediction by small bowel length of >25% of expected for gestational age and remaining ileocaecal valve.CONCLUSION: Preterm neonates with IF, at high risk of IF associated morbidity, showed a high overall survival rate. Small-bowel length and being born 2009-2016 were predictors for survival and remaining ICV and small-bowel length were predictors for enteral autonomy.

- Background: Surgery for total colonic aganglionosis (TCA) is designed to preserve continence and achieve satisfactory quality of life. This study evaluated a comprehensive group of clinical and social outcomes.Methods: An international multicentre study from eight Nordic hospitals involving examination of case records and a patient-reported questionnaire survey of all patients born with TCA between 1987 and 2006 was undertaken.Results: Of a total of 116 patients, five (4 center dot 3 per cent) had died and 102 were traced. Over a median follow-up of 12 (range 0 center dot 3-33) years, bowel continuity was established in 75 (73 center dot 5 per cent) at a median age of 11 (0 center dot 5-156) months. Mucosectomy with a short muscular cuff and straight ileoanal anastomosis (SIAA) (29 patients) or with aJpouch (JIAA) (26) were the most common reconstructions (55 of 72, 76 per cent). Major early postoperative complications requiring surgical intervention were observed in four (6 per cent) of the 72 patients. In 57 children aged over 4 years, long-term functional bowel symptoms after reconstruction included difficulties in holding back defaecation in 22 (39 per cent), more than one faecal accident per week in nine (16 per cent), increased frequency of defaecation in 51 (89 per cent), and social restrictions due to bowel symptoms in 35 (61 per cent). Enterocolitis occurred in 35 (47 per cent) of 72 patients. Supplementary enteral and/or parenteral nutrition was required by 51 (55 per cent) of 93 patients at any time during follow-up. Of 56 responders aged 2-20 years, true low BMI for age was found in 20 (36 per cent) and 13 (23 per cent) were short for age.Conclusion: Reconstruction for TCA was associated with persistent bowel symptoms, and enterocolitis remained common. Multidisciplinary follow-up, including continuity of care in adulthood, might improve care standards in patients with TCA.

Tidskriftsartikel (refereegranskat)abstract
- Rhabdomyomatous mesenchymal hamartoma (RMH) is a rare hamartomatous lesion in the dermis and subcutaneous tissue. It is mostly found in the face and neck region of children. We report a case of solitary RMH located in the perineum of an 8-month-old boy. Microscopic examination of specimen showed a disordered collection of mature adipose tissue, skeletal muscle, adnexal elements and nerve bundles, and immunohistochemistry confirmed a RMH. This case emphasizes the possibility of RMH in the perineum of the children. Even if RMH is a rare condition in the perineum it should be considered as a differential diagnosis of a perineal mass in children.

- Background: Necrotizing enterocolitis (NEC) is an inflammatory bowel disease in preterm neonates with high morbidity and mortality. The only treatment available is supportive with broad-spectrum antibiotics and gastrointestinal rest. Better understanding of the pathogenesis is crucial for the development of new therapies. Vascular adhesion protein-1 (VAP-1), expressed in human blood vessels and lymphatic, plays a crucial role in the pathogenesis of inflammatory diseases in adults. The aim of the study was to investigate the VAP-1 expression in the intestines of infants affected by NEC.Methods: Intestinal tissues from 42 preterm infants with NEC were examined with immunohistochemical staining using antibodies against VAP-1 and semi-automated digital image analysis was performed to determine tissue protein expression of VAP-1 in blood vessels located in the submucosa. Intestinal tissue from 26 neonates that underwent laparotomy and ileostomy due to other intestinal surgical conditions served as controls. Clinical data and protein expression were compared between the NEC-group and Controls.Results: Mean gestational age was lower in NEC infants compared to controls, 26.6 +/- 3.0 gestational weeks versus 36.5 +/- 4.0 (p < 0.001) but without any significant difference in median postnatal age at surgery; for NEC 8 (5-27) days and for controls 3 (1-36) days (p = 0.6). Low VAP-1 correlated with increased risk for developing NEC in the logistic regression (p < 0.001). Multiple linear regression showed that both gestational age and NEC were independent predictors of VAP-1 expression.Conclusion: VAP-1 may play a role in the pathogenesis of NEC. Diminished expression of VAP-1 independent of maturation could indicate arrested vascular development in infants suffering from NEC. Further studies are needed to elucidate the role of VAP-1 in NEC.

- Background:Newborn infants with short bowel syndrome (SBS) represent a high risk group of developing intestinal failure-associated liver disease (IFALD) which may be fatal. However, infants have a great capacity for intestinal growth and adaptation if IFALD can be prevented or reversed. A major contributing factor to IFALD may be the soybean oil-based intravenous lipid emulsions used since the introduction of parenteral nutrition (PN) 40 years ago. Methods:This retrospective study compares the outcome in 20 neonates with SBS treated with parenteral fish oil (Omegaven) in combination with omega-6/9 lipid emulsions (ClinOleic) with the outcome in a historical cohort of 18 patients with SBS who received a soybean oil-based intravenous lipid emulsion (Intralipid).Results:Median gestational age was 26 weeks in the treatment group and 35.5 weeks in the historical group. All patients were started on PN containing Intralipid that was switched to ClinOleic/Omegaven in the treatment group at a median age of 39 gestational weeks. In the treatment group, direct bilirubin levels were reversed in all 14 survivors with cholestasis (direct bilirubin >50 umol/). Median time to reversal was 2.9 months. Only 2 patients died of liver failure (10%). In the historical cohort, 6 patients (33%) died of liver failure and only 2 patients showed normalization of bilirubin levels.Conclusions:Parenteral fish oil in combination with omega-6/9 lipid emulsions was associated with improved outcome in premature neonates with SBS. When used instead of traditional soybean-based emulsions, this mixed lipid emulsion may facilitate intestinal adaptation by increasing the IFALD-free period.

- Laparoscopic gastrostomy (LAPG) has gained popularity in children. The aim of this study was to compare the outcome of LAPG versus open gastrostomy (OG) in children with focus on complications, operative times and postoperative length of stay. Retrospective study of children who had gastrostomies inserted at our tertiary Pediatric Surgery Center from 2000 until 2013. The indications for a gastrostomy were an anticipated need for enteral support for at least 6 months. Totally 243 children were included in the study, 83 with LAPG and 160 with OG. We found a significant difference in postoperative length of stay, 3 days in the LAPG group versus 4 days in the OG group but no difference in a sub-group analysis from 2010 to 2013 when both techniques were used. There was no difference in median operative time or complications rates. Granuloma was the dominating complication in both groups. These two feeding-access techniques are comparable regarding complications, operative times and postoperative length of stay. The choice of surgical method should be individualized based on the patient's characteristics and the experience of the surgeon. The favorable results with LAPG in adults are not necessarily transferable to children since there are physiological and anatomical differences.

- BackgroundThe aims of this study were to compare the incidence of small bowel obstruction (SBO) requiring laparotomy after laparoscopic appendectomy (LA) and open appendectomy (OA) in children and to identify risk factors for SBO.MethodsMedical records of patients who underwent appendectomy from 2000 to 2014 at our department of Pediatric Surgery were reviewed. Risk factors were analyzed using Cox proportional hazard regression.ResultsTotally 619 out of 840 patients were included. OA was performed in 474 (76.6%), LA in 130 patients (21%), and 15 (2.4%) were converted from LA to OA. Age, sex and proportion of perforated appendicitis were comparable in the LA and OA groups. Median follow-up time was 11.4 years (2.6–18.4). The incidence of SBO after LA was 1.5%, after OA 1.9% and in the converted group 6.7% (p = 0.3650). There were no significant differences in the incidence of postoperative intraabdominal abscess, wound infection or length of stay between LA and OA. Perforation and postoperative intra-abdominal abscess were identified as risk factors with 9.03 (p < 0.001) and 6.98 (p = 0.004) times higher risk of SBO, respectively.ConclusionsThe risk for SBO after appendectomy in children was significantly related to perforated appendicitis and postoperative intra-abdominal abscess and not to the surgical approach.Level of EvidenceLevel III.

- Aim: Several studies in animal models have found that exposure to anesthetics in early life can cause cognitive dysfunction. Human studies show conflicting results and studies of cognitive function after anesthesia and neonatal surgery are scarce. The aim of this study was to investigate whether exposure to anesthesia and abdominal surgery during infancy was associated with cognitive dysfunction from the perspective of educational level, disposable income and attention deficit hyperactivity disorders (ADHD) in adolescent and adult individuals.Methods: A cohort study with patients born 1976 to 2002 that underwent abdominal surgery during infancy at a pediatric surgical center were matched by age, sex, and gestational age to ten randomly selected individuals from the Swedish Medical Birth Register. Individuals with chromosomal aberrations were excluded. Data on highest level of education and annual disposable income were attained from Statistics Sweden and the diagnosis of ADHD were retrieved from the Swedish National Patient Register.Results: 485 individuals and 4835 controls were included. Median gestational age was 38 weeks (24-44) and median age at surgery was seven days (0-365). Three hundred sixty-six individuals (70.0%) underwent surgery during the neonatal period (< 44 gestational weeks). Median operating time was 80 minutes (10-430). The mean age at follow-up was 28 years. Fisher's exact test for highest level of education for the exposed and unexposed groups were respectively: university 35% and 33%, upper secondary 44% and 47%, compulsory 21% and 20% (p = 0.6718). The median disposable income was 177.7 versus 180.9 TSEK respectively (p = 0.7532). Exposed individuals had a prevalence of ADHD of 5.2% and unexposed 4.4% (p = 0.4191).Conclusions: This study shows that exposure to anesthesia and abdominal surgery during infancy is not associated with cognitive dysfunction from the perspective of educational level, disposable income and ADHD in adolescent and adult individuals. Further studies in larger cohorts at earlier gestational ages are needed to verify these findings.

- To examine whether hepatocytes transplanted in the spleen can function as an ectopic liver, we performed hepatocyte transplantation in rats that were rendered anhepatic, Total hepatectomy was performed by using a novel single-stage technique. Following hepatectomy, Group 1 rats (n = 16) were monitored until death to determine survival time without prior intervention. Group 2 anhepatic rats (n = 20) were sacrificed at various times to measure blood hepatocyte growth factor (HGF) and transforming growth factor beta 1 (TGF-beta 1) levels. Group 3 (n = 16) rats received intrasplenic injection of isolated hepatocytes (2.5 x 10(7) cells/rat) followed by total hepatectomy after 3 days. Group 4 (n = 12) sham-transplanted rats received intrasplenic saline infusion, and after 3 days they were rendered anhepatic, Group 2, 3, and 4 rats were maintained on daily Cyclosporine A (10 mg/kg; intramuscularly). Group I anhepatic rats survived for 22.4 +/- 5.2 hours (standard deviation). The anhepatic state was associated with a progressive and statistically significant rise in blood HGF and TGF-beta 1 levels. Rats that received hepatocyte transplantation before total hepatectomy had a significantly longer survival time than sham-transplanted anhepatic controls (34.1 +/- 8.5 vs. 15.5 +/- 4.8 hrs, P < .01), Additionally, at 12 hours post-hepatectomy, transplanted rats had significantly lower blood ammonia, prothrombin time, international normalized ratio, and TGF-beta 1 levels when compared with sham-transplanted controls, In conclusion, intrasplenic transplantation of allogeneic hepatocytes prolonged survival, improved blood chemistry, and lowered blood TGF-beta 1 levels in rats rendered anhepatic.
