Swallowing-related quality of life in children with oesophageal atresia: a national cohort study.

Swallowing and feeding disorders are a major concern for children with oesophageal atresia (OA) after primary or staged OA repair. Primary OA repair is associated with higher rates of short-term complications in preterm infants with very low birth weight (VLBW) or extreme low birth weight (ELBW). On the other hand, primary repair may have the benefit of early commencement of oral feedings. We hypothesize that also in the medium-term, swallowing-related quality of life is better after primary oesophageal repair. We conducted a prospective cross-sectional study on swallowing quality in a national cohort of former VLBW and ELBW children with OA, using the structured paediatric swallowing quality of life (pedSWAL-QOL) questionnaire. Results were correlated with surgical approach and baseline clinical data. Principal component analysis of pedSWAL-QOL domains was performed. In total, 44 complete data sets of 78 children were available. The mean age of children was 8.5 years (SD = 7.4), and 23 children (52%) had primary OA repair. The overall median pedSWAL-QOL score was 2 (IQR = 0-3), representing a high swallowing-related quality of life, independent of surgical technique (p = 0.086). Children with a history of intracranial haemorrhage (ICH) (p = 0.002) and those with VACTERL association (p = 0.008) had significantly decreased enjoyment with eating. In addition, children with VACTERL association had problems to find suitable foods (p = 0.04). CONCLUSION: In this national cohort of VLBW and ELBW preterm-born children with OA, swallowing-related quality of life is good, mostly independent of initial surgery. Children with OA and ICH or VACTERL association may require more intense support with feeding. WHAT IS KNOWN: • Dysphagia, resembling feeding and swallowing disorders, is common in children and adults with repaired oesophageal atresia. Nevertheless, dysphagia in children with oesophageal atresia decreases with age. • Parents of younger children suffer from increased anxiety and fear regarding eating and swallowing abilities of their children. WHAT IS NEW: • Swallowing-related quality of life in former preterm children with oesophageal atresia is good, independent of initial surgical approach (primary vs. staged repair), even in very low birth weight or extreme low birth weight infants. • Children suffering from VACTERL association or intracranial haemorrhage show decreased enjoyment with eating.

Evaluation of an Integrated Smart Sensor System for Real-Time Characterization and Digitalization of Postoperative Abdominal Drain Output: A Pilot Study.

Background: For centuries, surgeons have relied on surgical drains during postoperative care. Despite all advances in modern medicine and the area of digitalization, as of today, most if not all assessment of abdominal secretions excreted via surgical drains are carried out manually. We here introduce a novel integrated Smart Sensor System (Smart Drain) that allows for real-time characterization and digitalization of postoperative abdominal drain output at the patient's bedside. Methods: A prototype of the Smart Drain was developed using a sophisticated spectrometer for assessment of drain output. The prototype measures 10 × 6 × 6 cm and therefore easily fits at the bedside. At the time of measurement with our Smart Drain, the drain output was additionally sent off to be analyzed in our routine laboratory for typical markers of interest in abdominal surgery such as bilirubin, lipase, amylase, triglycerides, urea, protein, and red blood cells. A total of 45 samples from 19 patients were included. Results: The measurements generated were found to correlate with conventional laboratory measurements for bilirubin (r = .658, P = .000), lipase (r = .490, P = .002), amylase (r = .571, P = .000), triglycerides (r = .803, P = .000), urea (r = .326, P = .033), protein (r = .387, P = .012), and red blood cells (r = .904, P = .000). Conclusions: To our best knowledge, for the first time we describe a device using a sophisticated spectrometer that allows for real-time characterization and digitalization of postoperative abdominal drain output at the patient's bedside.

Esophageal Perforation and EVAC in Pediatric Patients: A Case Series of Four Children.

Introduction: In pediatric patients, esophageal perforation (EP) is rare but associated with significant morbidity and mortality rates of up to 20-30%. In addition to standard treatment options, endoscopic esophageal vacuum-assisted closure (EVAC) therapy has shown promising results, especially in adult patients. Thus far, the only data on technical success and effectiveness of EVAC in pediatric patients were published in 2018 by Manfredi et al. at Boston Children's Hospital. The sparse data on EVAC in children indicates that this promising technique has been barely utilized in pediatric patients. More data are needed to evaluate efficacy and outcomes of this technique in pediatric patients. Method: We reviewed five cases of therapy using EVAC, ArgyleTM Replogle Suction Catheter (RSC), or both on pediatric patients with EP in our institution between October 2018 and April 2020. Results: Five patients with EP (median 3.4 years; 2 males) were treated with EVAC, RSC, or a combination. Complete closure of EP was not achieved after EVAC alone, though patients' health stabilized and inflammation and size of EP decreased after EVAC. Four patients then were treated with RSC until the EP healed. One patient needed surgery as the recurrent fistula did not heal sufficiently after 3 weeks of EVAC therapy. Two patients developed stenosis and were successfully treated with dilatations. One patient treated with RSC alone showed persistent EP after 5 weeks. Conclusion: EVAC in pediatric patients is technically feasible and a promising method to treat EP, regardless of the underlying cause. EVAC therapy can be terminated as soon as local inflammation and C-reactive protein levels decrease, even if the mucosa is not healed completely at that time. A promising subsequent treatment is RSC. An earlier switch to RSC can substantially reduce the need of anesthesia during subsequent treatments. Our findings indicate that EVAC is more effective than RSC alone. In some cases, EVAC can be used to improve the tissues condition in preparation for a re-do surgery. At 1 year after therapy, all but one patient demonstrated sufficient weight gain. Further prospective studies with a larger cohort are required to confirm our observations from this small case series.

Establishment of a Pediatric Surgical Unit at a University Hospital in Eastern Africa.

INTRODUCTION: Ethiopia is a rapidly developing country in Eastern Africa. In total, 43.2% of the population are younger than 15. In contrast, until a few years ago, pediatric surgery was only available in Addis Ababa. Now, Ethiopia is making great efforts to improve the care of children who require surgery. JimmaChild was established to set up a pediatric surgery in Jimma. MATERIAL AND METHODS: JimmaChild developed from a scientific collaboration between Jimma University (JU) and Ludwig-Maximilians-University. The project was developed and realized by Ethiopian and German colleagues. A curriculum was written for this purpose. The pediatric surgical training of the fellows was carried out on-site by German pediatric surgeons. RESULTS: A new pediatric surgery was established at JU with its own operating room, ward, and staff. After two and a half years, two fellows completed their final examinations as pediatric surgeons. Among others, 850 elective surgeries were performed, 82% assisted by the German colleagues. The German colleagues rated the preparation for the trip, the on-site support, and the professional progress of the fellows mostly as good to very good. Reported problems in the program flow were also recognized and solved in part. CONCLUSIONS: The best possible integration of the project into existing structures was achieved by close cooperation of Ethiopian and German colleagues during the project development. Problems were identified and addressed early on by external monitoring. As the project responsibility was mainly with the Ethiopian colleagues, a department was created that now exists independently of external funding and trains its own fellows.

Outcome of Patients With Esophageal Atresia and Very Low Birth Weight (≤ 1,500 g).

Introduction: Primary repair of esophageal atresia (EA) in infants with very low birth weight (VLBW) and extremely low birth weight (ELBW) has been widely performed in pediatric surgery. However, several studies have shown that complication rates in infants with VLBW are high. We hypothesize preterm children benefit from a shorter, less-traumatizing operation in the first days of life, as staged repair implies. Methods: Patients with EA and VLBW were retrieved from the database of a large national patient organization KEKS e.V. Structured questionnaires were sent to all the patients' families; the responses were pseudonymized and sent to our institution. Results: Forty-eight questionnaires from patients were analyzed. The mean birth weight was 1,223 g (720-1,500 g). Primary repair was performed in 25 patients (52%). Anastomotic insufficiency (AI) was reported in 9 patients (19%), recurrent fistula (RF) in 8 (17%), and anastomotic stenosis in 24 patients (50%). Although AI was almost twice as common after primary repair than after staged repair (24 vs. 13%; p = 0.5), the difference was not statistically significant. RF was more frequent after primary repair (28 vs. 4%; p = 0.04), gastroesophageal reflux was more frequent in the group after staged repair (78 vs. 52%; p = 0.04), and both correlations were statistically significant. Intracranial hemorrhage (ICH) was reported in 11 patients (23%) and was observed in 7 of them (64%, p = 0.4) after primary repair. ICH was reported in 60% of patients with ELBW and 75% of patients when ELBW was paired with primary repair. Conclusion: This study demonstrates the complication rate in patients with VLBW is higher than the average of that in patients with EA. The study indicates that a staged approach may be an option in this specific patient group, as less RF and AI are seen after staged repair. ICH rate in patients with ELBW seemed to be especially lower after staged repair. Interestingly, gastroesophageal reflux was statistically significantly higher in the group after staged repair, and postoperative ventilation time was longer. It is therefore necessary to individually consider which surgical approach is appropriate for this special patient group.

Long-Term Follow-Up Examination of the Internal Jugular Vein After Vessel-Sparing Implantation of a Hickman Catheter or Port Catheter.

Introduction: Both a Hickman catheter (HC) and port catheter (Port) can be inserted either percutaneously by the Seldinger technique or by surgical venous cut-down. Catheters are inserted with a vessel-sparing technique when they are placed in the internal jugular vein (IJV) by venous cut-down. Although this technique is common, data are sparse regarding the vessel's state at long-term follow-up. This study was aimed at determining the flow pattern and constitution of the IJV after vessel-sparing implantation of an HC or Port and comparing the outcomes to those of implantation with the Seldinger technique. Methods: One hundred children (58 boys, 42 girls) between 33 days and 18 years of age who underwent a vessel-sparing implantation of an HC or Port in the IJV were prospectively included. All patients underwent surgical venous cut-down at a single institution. Patency and shape of the IJV were determined by ultrasound and categorized according to 2 possible outcomes: relevant alteration (including occlusion of the IJV) and no relevant alteration, with relevant alteration defined as changes that caused an altered flow pattern. Results: Median age was 6 years at the time of operation, and the median indwelling time of catheters was 271 days. Twenty-two of our patients (22%) showed relevant alterations. These changes included high-grade stenosis or lesion in 13 patients (13%) and occlusion in 9 patients (9%). There were no operation-associated complications, such as pneumothorax, hematopericardium, or accidental puncture of the carotid artery. Statistical analysis did not reveal any specific parameter as a risk factor for relevant structural abnormalities. Discussion: In a comparison of our data to the literature, venous cut-down showed an alteration rate of 26% and a patency rate of 85%, whereas the Seldinger technique was found to cause alteration in 15%, with a patency rate of 97% but a successful placement rate of only 90.3-91.6%. Conclusion: The indication for long-term catheter placement may determine which method is preferable. A child who is likely to need more catheters in the future might benefit from the Seldinger technique, since there is a higher chance of long-term patency of the vessel. A patient undergoing chemotherapy might benefit more from the surgical venous cut-down with less placement-associated complications.
