Introduction: Pilonidal sinus (PS) is an infectious/inflammatory condition of the sacrococcygeal region, with frequent relapses. There is no clear consensus as to which management technique is best. The most widely used technique is en bloc resection (EBR), but less invasive methods (Gips procedure) are now being developed., Objective: To compare complications and progression of pediatric patients undergoing PS surgery in our institution using two different surgical techniques., Material and Methods: A retrospective study of patients under 16 years of age undergoing PS surgery (EBR/Gips procedure) for the first time from 2014 to 2020 was carried out. Demographic variables, complications in the first month (exudate, wound infection, dehiscence, and bleeding), and result at the end of follow-up were collected. Qualitative variables were expressed as absolute frequency and percentage, whereas quantitative variables were expressed as mean and standard deviation., Results: 60 patients underwent surgery. EBR was used in the first group, and the Gips procedure was used in the second group (76.67%, n = 46 vs. 23.33%, n = 14). Both were comparable in terms of sex (32.61% vs. 35.71% male), age (14.04 vs. 13.79 years old), and BMI (26.63 vs. 26.20 kg/m2) at surgery. 6 patients underwent re-intervention (10.87% vs. 7.14%; p = 0.684). Median follow-up time to healing was 6.13 ± 0.98 months vs. 3.31 ± 1.26 months (p < 0.024). The Gips procedure caused no dehiscence, whereas dehiscence rate in EBR was 65.22%., Conclusion: The Gips procedure is a minimally invasive alternative to EBR. It avoids dehiscence, and time to healing is shorter. Therefore, it should be regarded as the first-line treatment in PS patients.

Introduction: Neonatal airway examination through flexible/rigid bronchoscopy has proved to be useful in the presence of persistent stridor and extubation failure, as well as to assess complications following cardiac surgery. At our institution, these examinations are carried out by a pulmonologist, a neonatologist, an otorhinolaryngologist, and a pediatric surgeon from the pediatric airway committee, established in 2014., Objective: To analyze the airway examinations performed in neonates during their stay at the neonatology/neonatal intensive care unit since the airway committee was established., Material and Methods: A retrospective study of the airway examinations conducted in neonates from 2015 to 2019 was carried out. Clinical and demographic data, number of examinations, indications, findings, and complications were collected. Results are presented as mean and standard deviation. Statistical significance was established at p < 0.05., Results: 92 airway examinations were analyzed in 51 patients (54.9% of whom were female). 51% of the patients were premature. Extubation failure and persistent respiratory symptoms following successful extubation were the most frequent indications for airway examination (35.3%). Stratification by gestational age or weight at birth was not associated with an increased risk of pathological findings at examination (p > 0.05). The most frequent finding was vocal cord paralysis (n = 14; 27.5%). In 10 patients (19.6%), no pathological findings were observed., Conclusion: Airway examination is useful in patients with stridor to identify vocal cord paralysis following extubation failure. It also allows congenital airway pathologies to be diagnosed and treated. The number of examinations with no pathological findings was similar to that reported in international series.

Introduction: Graft-versus-host disease (GVHD) is a frequent complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT), with high morbidity and mortality rates. Intestinal clinical signs are unspecific, which means differential diagnosis with infections and drug-related etiology should be carried out. Even though intestinal biopsy is widely considered as the gold standard technique, there is no consensus as to which sampling method is best., Objective: To assess the results of the biopsy techniques used in patients with suspected intestinal GVHD., Material and Methods: A retrospective study of patients with suspected intestinal GVHD undergoing allo-HSCT from 2010 to 2019 was carried out. They were assessed through digestive biopsy - esophagogastroduodenal biopsy (upper GI endoscopy - UGIE) or rectal biopsy (colonoscopy or direct biopsy). Quantitative variables, expressed as median and interquartile range, and qualitative variables, expressed as absolute frequency and percentage, were collected., Results: 23 patients were studied, 60.9% of whom were male. Median age at biopsy was 9 years (7-14 years). UGIE was used in 47.8% of patients (n=11), colonoscopy was used in 26.1% of patients (n=6), and direct biopsy was used in 34.8% of patients (n=8), with GVHD positive results in 2 (18.2%), 2 (33.3%), and 4 (50%) patients, respectively., Conclusions: Samples taken through direct biopsy stand as an effective alternative in GVHD diagnosis.

Introduction: Recurrent tracheoesophageal fistula (RTEF) is a frequent complication (5-10%) in patients with esophageal atresia (EA). Open RTEF surgery has a high morbidity and mortality, so the endoscopic approach represents a promising alternative. We present the long-term results of fibrin glue (FG) bronchoscopic application in patients with RTEF secondary to EA, which was first used by our team in 1994., Material and Methods: A retrospective review of all patients diagnosed with RTEF following EA repair and treated with FG bronchoscopic application from 1993 to 2019 was carried out. In most cases, diathermy was applied prior to FG sealing. The maximum number of endoscopic sessions was 5. In case of persistent RTEF following the fifth session, open surgery was performed., Results: 14 RTEF patients were treated with FG. In all but the first 3 cases (11 patients, 78.6%), diathermy was applied concomitantly. Mean first treatment day was day 85 of life (range: 14-770). Patients received a mean of 2.1 (1-5) endoscopic sessions. Mean follow-up was 12.1 (10-20) years. Overall success rate was 71.4%, without significant differences according to whether diathermy was concomitantly applied or not (72.7% vs. 66.6%)., Conclusions: Fibrin glue bronchoscopic application associated or not associated with diathermy is an excellent option for RTEF treatment in EA patients. The endoscopic approach should be considered as the first-choice treatment for RTEF.
