Abstract
BACKGROUND Congenital h-type tracheoesophageal fistula (H-TEF) without esophageal atresia (EA) represents about 4% of congenital esophageal anomalies. The diagnosis is challenging, and surgery is considered curative. The aim was to report a national survey on the diagnosis, management, and outcome of patients with congenital H-TEF. METHODS Following approval of the Italian Society of Pediatric Surgery, a survey was sent to all Pediatric Surgery Units to retrospectively collect H-TEF treated in the period 2010-2022. Descriptive analysis was performed, and results are given as prevalence, mean ± standard deviation (SD), or median and interquartile range (IQR). RESULTS The survey was sent to 65 units. Seventeen responded with one or more cases; 78 patients were diagnosed with H-TEF during the study period. Associated malformations were present in 43%, mostly cardiac (31%). The most frequent symptoms were cough (36%), bronchopneumonia (24%), and dysphagia (19%). H-TEF was detected by tracheobronchoscopy (90%), and/or upper GI (58%), and/or esophagoscopy (32%). The median age at diagnosis was 23 days (1 day-18 years). The most common approach was cervicotomy (76%), followed by thoracoscopy (14%) and thoracotomy (9%). The fistula underwent ligation and section of the fistula in 90% of the patients and clip closure and section in 9%. In one patient, the fistula was cauterized endoscopically. H-TEF preoperative cannulation was performed in 68% of cases, and a drain was placed in 26%. One month after surgery, 13% of the patients had mild persisting symptoms, mainly hypophonia. Recurrence occurred in 5%, and a second recurrence occurred in 1%. CONCLUSIONS H-TEF prevalence was six cases/year, consistent with the expected rate of five cases/year in our country. The diagnosis was challenging, sometimes delayed, and, in most patients, required multiple examinations. Fistula ligation and section through cervicotomy were the most frequent treatment. Long-term outcomes are good, and recurrence is a rare event.

Abstract
The combination of pharmacologic and endoscopic therapies is the gold standard for treating intestinal failures. The possibility of chemical solubility in water is mandatory for intelligent capsules. Functionalised silk fibroin with peptides and covalently linking different molecular entities to its structure make this protein a platform for preparing gels dissolving in the small and large intestine for drug delivery. In the present study, we linked a peptide containing the cell-adhesive motif Arginine–Glycine–Aspartic acid (RGD) to degummed silk fibres (DSF). Regenerated silk fibroin (RS) films obtained by dissolving functionalised DSF in formic acid were used to prepare composite gelatin. We show that such composite gelatin remains stable and elastic in the simulated gastric fluid (SGF) but can dissolve in the small and large intestines’ neutral-pH simulated intestine fluid (SIF). These findings open up the possibility of designing microfabricated and physically programmable scaffolds that locally promote tissue regeneration, thanks to bio-enabled materials based on functionalised regenerated silk.

Abstract
AbstractAcquired vaginal strictures are rare entities in children. As a result, they are generally difficult to manage and tend to recur despite appropriate initial therapy. This case study reports the staged management of vaginal stenosis following the insertion of a button battery. In this case, an 11-year-old girl experienced at 4 years old a battery insertion in the vaginal canal by her neighbor's son, who was 6-year-old at the time. Two weeks from insertion, the parents noted the foreign body discharge spontaneously. The girl had not complained of any symptoms at the time and had been asymptomatic for many years. In November 2020, she came to the emergency department reporting cramping abdominal pain accompanied by mucopurulent discharge. An abdominal ultrasound showed the presence of hematometrocolpos, and a vaginal stenosis dilation under general anesthesia was performed the following day. After 3 weeks, the stenosis was still present, preventing the passage of Hegar number 4. The girl was subjected to a vaginoscopic stenosis resection utilizing a monopolar hook passed through an operative channel. A Bakri catheter filled with 120 mL of water was left in place. After 10 days, the girl was discharged home with the Bakri inserted. Two weeks after discharge, she was reevaluated in the outpatient setting, where the Bakri was removed with no signs of residual stenosis. Acquired vaginal stenosis could be demanding to treat, particularly with the sole conservative approach. A first-line option can be the Hegar dilation. The endoscopic approach can be a second-line, minimally invasive treatment, but long-term outcomes are difficult to predict.
