To evaluate the utilization of double-J stents in children with congenital hydronephrosis in order to avoid or postpone more invasive surgical intervention. Numerous studies have demonstrated that ...congenital hydronephrosis caused by ureteropelvic junction obstruction (UPJO) or primary obstructive megaureter (POM) may require a surgical correction in up to 20% of cases.
All infants with severe hydronephrosis and/or an obstructive pattern on renal scintigraphy that received double-J stent placement between 2010 to 2015 in our center were analyzed. Children were followed regularly with ultrasound and received antibiotic metaphylaxis. Urinary tract infection (UTI) and double-J dislocation were defined as complications. Treatment success was defined as avoidance of surgery and reduction of hydronephrosis to grade 1 or 0 during the observation period.
29 children were included, in these, 34 (23 UPJO, 7 POM, 4 UPJO and POM) treatment attempts were performed. Stent implantation failed in six cases, resulting in 28 double-J stent treatments, of which 19 (69%) were successful within the follow-up period of 20 to 104 months. The most common complications were febrile UTI in 6 of29 cases and double-J dislocation in 3 of 29 cases.
During the observation period, the success rate of temporary double-J in urodynamically relevant obstruction was relatively high. However, urinary tract infections and a complex disease course due to renal stent dislocation, as well as the need for repeated anesthesia and radiation exposure, should be taken into account. Hence, we do not recommend double-J stents placement in all children with congenital hydronephrosis; it may be useful in selected cases.
•Bacterial nanocellulose (BNC)-dressings reduce length of hospital stay.•BNC-dressings reduce the number of interventions requiring general anesthesia.•A temporary epidermal substitute from first ...application until reepithelialization.•Cost-effective and easy treatment with excellent patient comfort.
Management of pediatric thermal injuries involves a high standard of care in a multidisciplinary setting. To avoid physical and psychological sequelae, wound dressings should minimize hospitalization time and anesthesia while maximizing patient comfort.
190 children with thermal injuries of the torso, arms and legs were treated with polyurethane foam dressings or bacterial nanocellulose sheets. Data were analyzed retrospectively regarding hospitalization, procedures with general anesthesia, scar formation, rate of infection and need for skin grafting.
The groups did not differ significantly concerning age, gender distribution or percentage of injured total body surface area. Statistical analysis showed that length of hospitalized care and procedures undergoing anesthesia were significantly reduced in the nanocellulose group (each p < 0.0001). There was no significant difference in rate of complications, wound healing and rate of skin grafting between the two subgroups.
Acting as a temporary epidermal substitute, bacterial nanocellulose enables undisturbed reepithelialization without further wound dressing changes. In children, no additional topical antimicrobial agents are indicated for unimpaired wound healing.
Bacterial nanocellulose is superior to polyurethane foam regarding length of hospitalization and number of interventions under anesthesia. It offers a safe, cost-effective treatment option and provides excellent comfort in pediatric patients.
To review our institutional results and assess different surgical and non-surgical techniques for the treatment of displaced diametaphyseal forearm fractures in children and adolescents.Thirty-four ...children (25M, 9F) with a total of 36 diametaphyseal forearm fractures who underwent treatment under general anesthesia between July 2010 and February 2016 were recruited to this retrospective study. From October 2016 until March 2018 patients and/or parents were contacted by telephone and interviewed using a modified Pediatric Outcomes Data Collection Instrument (PODCI).Median age at the time of injury was 9.1 years (range, 1.9-14.6 years). Initial treatment included manipulation under anesthesia (MUA) and application of plaster of Paris (POP) (n = 9), elastic stable intramedullary nailing (ESIN) (n = 10), percutaneous insertion of at least one Kirschner wire (K-wire) (n = 16), and application of external fixation (n = 1). Eleven children (32%) experienced a total of 22 complications. Seven complications were considered as major, including delayed union (n = 1) and extensor pollicis longus (EPL) tendon injury (n = 1) following ESIN, as well as loss of reduction (n = 2) and refractures (n = 3) after MUA/POP. The median follow-up time was 28.8 months (range, 5.3-85.8 months). In 32 out of 34 cases (94%) patients and/or parents were contacted by telephone and a PODCI score was obtained. Patients who experienced complications in the course of treatment had a significantly lower score compared with those whose fracture healed without any sequelae (P = .001). There was a trend towards an unfavorable outcome following ESIN compared with K-wire fixation (P = .063), but not compared with POP (P = .553). No statistical significance was observed between children who were treated initially with a POP and those who had K-wire fixation (P = .216).There is no standard treatment for displaced pediatric diametaphyseal forearm fractures. Management with MUA/POP only is associated with an increased refracture rate. Based on our experience K-wire fixation including intramedullar positioning of at least one pin seems to be favorable compared with ESIN.
Short bowel syndrome (SBS) is a severe, life-threatening condition and one of the leading causes of intestinal failure in children. Here we were interested in changes in muscle layers and especially ...in the myenteric plexus of the enteric nervous system (ENS) of the small bowel in the context of intestinal adaptation. Twelve rats underwent a massive resection of the small intestine to induce SBS. Sham laparotomy without small bowel transection was performed in 10 rats. Two weeks after surgery, the remaining jejunum and ileum were harvested and studied. Samples of human small bowel were obtained from patients who underwent resection of small bowel segments due to a medical indication. Morphological changes in the muscle layers and the expression of nestin, a marker for neuronal plasticity, were studied. Following SBS, muscle tissue increases significantly in both parts of the small bowel, i.e., jejunum and ileum. The leading pathophysiological mechanism of these changes is hypertrophy. Additionally, we observed an increased nestin expression in the myenteric plexus in the remaining bowel with SBS. Our human data also showed that in patients with SBS, the proportion of stem cells in the myenteric plexus had risen by more than twofold. Our findings suggest that the ENS is tightly connected to changes in intestinal muscle layers and is critically involved in the process of intestinal adaptation to SBS.
Many aspects of the management of esophageal atresia (EA) and tracheoesophageal fistula (TEF) are controversial and the evidence for decision making is limited. Members of the European Reference ...Network for Rare Inherited Congenital Anomalies (ERNICA) conducted a consensus conference on the surgical management of EA/TEF based on expert opinions referring to the latest literature.
Nineteen ERNICA representatives from nine European countries participated in the conference. The conference was prepared by item generation, item prioritization by online survey, formulation of a final list containing the domains diagnostics, preoperative, operative, and postoperative management, and literature review. The 2-day conference was held in Berlin in October 2018. Anonymous voting was conducted via an internet-based system. Consensus was defined when 75% of the votes scored 6 to 9.
Fifty-two items were generated with 116 relevant articles of which five studies (4.3%) were assigned as level-1evidence. Complete consensus (100%) was achieved on 20 items (38%), such as TEF closure by transfixing suture, esophageal anastomosis by interrupted sutures, and initiation of feeding 24 hours postoperatively. Consensus ≥75% was achieved on 37 items (71%), such as routine insertion of transanastomotic tube or maximum duration of thoracoscopy of 3 hours. Thirteen items (25%) were controversial (range of scores, 1-9). Eight of these (62%) did not reach consensus.
Participants of the conference reached significant consensus on the management of patients with EA/TEF. The consensus may facilitate standardization and development of generally accepted guidelines. The conference methodology may serve as a blueprint for further conferences on the management of congenital malformations in pediatric surgery.
Despite limited research, existing studies using generic quality of life (QOL) tools indicate decreased physical health and compromised emotional functioning in children with IF. This study ...investigates QOL in children with short bowel syndrome (SBS) and its determinants. The study included 57 pediatric patients with SBS treated at Mannheim's University Hospital between 1998 and 2014. To evaluate QOL, the KINDL questionnaire was used. Three age-specific questionnaire variants were employed, and parental proxy reports were collected. Most patients underwent intestinal lengthening procedures, with varying primary diagnoses. A comparison with healthy children from the patient's perspective revealed no difference but from the parent's perspective showed lower QOL in SBS patients, especially regarding physical and mental well-being. QOL varied with age, with 7-10-year-olds reporting the lowest scores. Several factors, including independence from parenteral nutrition and the presence of a complete colon, positively influenced QOL. The independence of parenteral nutrition and the presence of a complete colon positively influenced QOL. The Bianchi technique for intestinal lengthening has also shown promise but needs further research. The observation sample in this study is too small to generalize about the whole population of SBS patients. However, this study shows that many health and treatment factors affect QOL, and a large multicenter study is necessary. Our findings underline the importance of appropriate psychological support for children with SBS and their families.
Abstract Purpose There is a lack of experience with covered self-expandable stents for benign colorectal disorders in children. Methods Five children (4 M, 1F) with a median age of 5 years (range, 6 ...months–9 years) who underwent treatment with covered self-expandable plastic (SEPSs) or self-expandable metal stents (SEMSs) for a benign colorectal condition between April 2005 and November 2013 were recruited to this retrospective study. Etiologies included: anastomotic stricture with (n = 1) or without (n = 3) simultaneous enterocutaneous fistula, as well as an anastomotic leak associated with enterocutaneous fistula (n = 1). All children suffered from either Hirschsprung's disease (n = 3) or total colonic aganglionosis (Zuelzer–Wilson syndrome) (n = 2). Results Median duration of individual stent placement was 23 days (range, 1–87 days). In all cases up to five different stents were placed over time. At follow-up two patients were successfully treated without further intervention. In another patient the anastomotic stricture resolved fully, but a coexisting enterocutaneous fistula persisted. Overall, three patients did not improve completely following stenting and required definite surgery. Stent-related problems were noted in all cases. There was one perforation of the colon at stent insertion. Further complications consisted of stent dislocation (n = 4), obstruction (n = 1), formation of granulation tissue (n = 1), ulceration (n = 1) and discomfort (n = 3). Conclusions Covered self-expandable stents enrich the armamentarium of interventions for benign colorectal disorders in children including anastomotic strictures and intestinal leaks. A stent can be applied either as an emergency procedure (bridge to surgery) or as an adjuvant treatment further to endoscopy and dilatation. Postinterventional problems are frequent but there is a potential for temporary or definite improvement following stent insertion.
Emphysema-like-change of lung is one aspect of lung morbidity in children after congenital diaphragmatic hernia (CDH). This study aims to evaluate if the extent of reduced lung density can be ...quantified through pediatric chest CT examinations, if side differences are present and if emphysema-like tissue is more prominent after CDH than in controls. Thirty-seven chest CT scans of CDH patients (mean age 4.5 ± 4.0 years) were analyzed semi-automatically and compared to an age-matched control group. Emphysema-like-change was defined as areas of lung density lower than - 950 HU in percentage (low attenuating volume, LAV). A p-value lower than 0.05 was regarded as statistically significant. Hypoattenuating lung tissue was more frequently present in the ipsilateral lung than the contralateral side (LAV 12.6% vs. 5.7%; p < 0.0001). While neither ipsilateral nor contralateral lung volume differed between CDH and control (p > 0.05), LAV in ipsilateral (p = 0.0002), but not in contralateral lung (p = 0.54), was higher in CDH than control. It is feasible to quantify emphysema-like-change in pediatric patients after CDH. In the ipsilateral lung, low-density areas are much more frequently present both in comparison to contralateral and to controls. Especially the ratio of LAV ipsilateral/contralateral seems promising as a quantitative parameter in the follow-up after CDH.
