Incidental finding of thyroglossal duct cyst in a neonate during endotracheal intubation: a case report.

BACKGROUND: Thyroglossal Duct Cyst (TDC) is a common lesion of the midline neck, originating from an incomplete involution of the thyroglossal duct. It is typically observed in pre-scholar patients and surgery is the treatment of choice to prevent infections. Here reported a case of incidental diagnosis in a newborn patient. CASE PRESENTATION: a 3-week-old male baby was admitted to our hospital for weight loss and projectile vomits after breastfeeding. After a diagnosis of hypertrophic pyloric stenosis, the baby underwent pyloromyotomy. During the endotracheal tube placement, the anesthetist noticed the presence of a midline neck mass. The suspect of TDC was confirmed by an intraoperative ultrasound, so, despite the age of the patient, we proceeded with the excision of the lesion according to Sistrunk's procedure to avoid future complications and anesthesia. CONCLUSIONS: even if TDC is a common lesion of pediatric patients, anecdotical neonatal cases were described in the literature, all of them symptomatic. An accurate physical examination and ultrasound are essential diagnostic tools to distinguish TDC from other middle neck lesions, particularly ectopic thyroidal tissue. Sistrunk's procedure is the most effective surgical approach. When diagnosis is made in a newborn, we suggest postponing surgery, unless the baby requires general anesthesia for other surgical procedures, such as in our case.

Congenital lung malformations: a nationwide survey on management aspects by the Italian Society of Pediatric Surgery.

INTRODUCTION: Over the years, congenital lung malformations (CLM) management remains a controversial topic in pediatric thoracic surgery. The Italian Society of Pediatric Surgery performed a national survey to study the current management variability among centers, trying to define national guidelines and a standardized approach of children with congenital lung malformations. METHODS: Following a National Society approval, an electronic survey including 35 items on post-natal management was designed, focusing on surgical, anesthesiology, radiology and pneumology aspects. The survey was conducted contacting all pediatric surgical units performing thoracic surgery. RESULTS: 39 pediatric surgery units (97.5%) participated in the study. 13 centers (33.3%) were classified as high-volume (Group A), while 26 centers (66.7%) were low volume (Group B). Variances in diagnostic imaging protocols were observed, with Group A performing fewer CT scans compared to Group B (p = 0.012). Surgical indications favored operative approaches for asymptomatic CLM and pulmonary sequestrations in both groups, while a wait-and-see approach was common for congenital lobar emphysema. Surgical timing for asymptomatic CLM differed significantly, with most high-volume centers operating on patients younger than 12 months (p = 0.02). Thoracoscopy was the preferred approach for asymptomatic CLM in most of centers, while postoperative long-term follow-up was not performed in most of the centers. CONCLUSION: Thoracoscopic approach seems uniform in asymptomatic CLM patients and variable in symptomatic children. Lack of uniformity in surgical timing and preoperative imaging assessment has been identified as key areas to establish a common national pattern of care for CLM.

Rectal atresia and rectal stenosis: the ARM-Net Consortium experience.

PURPOSE: To assess the number, characteristics, and functional short-, and midterm outcomes of patients with rectal atresia (RA) and stenosis (RS) in the ARM-Net registry. METHODS: Patients with RA/RS were retrieved from the ARM-Net registry. Patient characteristics, associated anomalies, surgical approach, and functional bowel outcomes at 1 and 5-year follow-up were assessed. RESULTS: The ARM-Net registry included 2619 patients, of whom 36 (1.3%) had RA/RS. Median age at follow-up was 7.0 years (IQR 2.3-9.0). Twenty-three patients (63.9%, RA n = 13, RS n = 10) had additional anomalies. PSARP was the most performed reconstructive surgery for both RA (n = 9) and RS (n = 6) patients. At 1-year follow-up, 11/24 patients with known data (45.8%, RA n = 5, RS n = 6) were constipated, of whom 9 required stool softeners and/or laxatives. At 5-year follow-up, 8/9 patients with known data (88.9%, RA n = 4, RS n = 4) were constipated, all requiring laxatives and/or enema. CONCLUSION: RA and RS are rare types of ARM, representing 1.3% of patients in the ARM-Net registry. Additional anomalies were present in majority of patients. Different surgical approaches were performed as reconstructive treatment, with constipation occurring in 46% and 89% of the patients at 1 and 5-year follow-up. However, accurate evaluation of long-term functional outcomes remains challenging.

Gynecological and psycho-sexual aspects of women with history of anorectal malformations.

PURPOSE: Women with anorectal malformation (ARM) are expected to have a normal life span, therefore, gynecological and psycho-sexual issues are also important. Aim of the study was to assess these aspects in adult females with history of ARM. METHODS: Thirty-seven women from two ARM referral centers, aged ≥ 16, were identified. Gynecologic visit, cervicovaginal swab, pelvic ultrasound, FSH, LH, prolactin, progesterone, 17-ß-estradiol, DHEAS, testosterone, TSH during follicular and luteal phases, and administration of FSFI questionnaire to screen the female sexual functioning were performed. Data were compared with six controls. RESULTS: Nineteen patients, mean age 21.7 (16-45), participated to the study. Associated anomalies, mostly affecting limbs, vertebrae and genitalia, were present in 57.8% of cases. Mullerian anomalies were retrieved in 36.8%. Hormones' levels were normal. Concerning sexual functioning, four women (21%) reported dyspareunia or impossible penetration, four did not answer the FSFI questionnaire due to lack of confidence about their sexuality, and three scored lower than the cut-off value for female sexual function. CONCLUSION: This study confirms the importance of a multidisciplinary long-term follow-up for ARM patients, including a careful study of the reproductive tract to detect and treat those conditions that could affect the fertility. Moreover, an appropriate psychological support should be provided.

Congenital Pouch Colon: Case Series and Review of Evidences for Resection.

BACKGROUND: Congenital pouch colon (CPC) is a rare variant of anorectal malformations (ARM) with its highest reported incidence in India. We aimed to describe five patients affected by CPC, in which the tissue from the terminal dilated colon has been successfully used and to discuss our results on the light of an extended revision of the literature. MATERIALS AND METHODS: The clinical details of five cases treated for CPC in two Italian Centers were retrospectively reviewed assessing the fate of the terminal dilated colon. RESULTS: In all cases, the tissue from dilated colon has been used. The double vascular system of the dilated pouch allowed increasing bladder capacity (case 4), reconstruction of the vagina (case 3, 5), and lengthening of the colon (case 1, 2, 5).In our series, 3/5 have a good bowel control with daily bowel management after ARM correction. In literature, there are not differences in terms of dependence from bowel management in patients with pouch resected and in patients with pouch saved (P = 0.16). CONCLUSIONS: We acknowledge that the analysis of the available literature is limited by the absence of studies with high level of evidence and the removal or the preservation of the abnormal colon tissue seems to follow the surgeon preferences.

Perineal Groove: An Anorectal Malformation Network, Consortium Study.

OBJECTIVE: To review the Anorectal Malformation Network experience with perineal groove (PG) focusing on its clinical characteristics and management. STUDY DESIGN: Data on patients with PG managed at 10 participating Anorectal Malformation Network centers in 1999-2019 were collected retrospectively by questionnaire. RESULTS: The cohort included 66 patients (65 females) of median age 1.4 months at diagnosis. The leading referral diagnosis was anal fissure (n = 20 [30.3%]): 23 patients (34.8%) had anorectal malformations. Expectant management was practiced in 47 patients (71.2%). Eight (17%) were eventually operated for local complications. The median time to surgery was 14 months (range, 3.0-48.6 months), and the median age at surgery was 18.3 months (range, 4.8-58.0 months). In the 35 patients available for follow-up of the remaining 39 managed expectantly, 23 (65.7%) showed complete or near-complete self-epithelization by a mean age 15.3 months (range, 1-72 months) and 4 (11.4%) showed partial self-epithelization by a mean age 21 months (range, 3-48 months). Eight patients showed no resolution (5 were followed for ≤3 months). Nineteen patients (28.7%) were primarily treated with surgery. In total, 27 patients were operated. Dehiscence occurred in 3 of 27 operated patients (11.1%). CONCLUSIONS: PG seems to be an underestimated anomaly, frequently associated with anorectal malformations. Most cases heal spontaneously; therefore, expectant management is recommended. When associated with anorectal malformations requiring reconstruction, PG should be excised in conjunction with the anorectoplasty.

The DATE Association: A Separate Entity or a Further Extension of the VACTERL Association?

BACKGROUND: The combination of esophageal atresia, congenital duodenal obstruction, and anorectal malformation has seldom been reported. We describe the largest series of patients with such association, which we summed up with the mnemonic acronym DATE [D-duodenal obstruction, A-anorectal malformation (ARM), and TE-tracheoesophageal fistula with esophageal atresia]. METHODS: This was a multicenter retrospective review of 13 patients recruited from 8 institutions over a nearly 5-decade period (1968-2017). Information gathered included type of DATE malformations, other associated anomalies, type and timing of surgery, and clinical outcomes. RESULTS: The DATE association consisted of type C esophageal atresia (13), complete (9) or incomplete (4) congenital duodenal obstruction (CDO), and high or intermediate (8) or low (5) ARM. Eight patients had at least one additional component feature of VACTERL association. A total of 6 patients died. Overall, 9 patients achieved complete restoration of gastrointestinal continuity, 7 of whom are alive at a median follow-up of 4 y (range, 1 to 9). Survivors received a median of 6 major operations (range, 4 to 14) to overcome their anomalies and surgical complications. Two incomplete duodenal obstructions were initially overlooked. All survivors with high or intermediate ARM defects required some form of bowel management to keep them clean. CONCLUSIONS: The DATE association is a low-frequency entity, often occurring among the wider spectrum of VACTERL association. Functional outcomes largely depend on the severity of ARM or other major associated malformations. Awareness of the DATE association may avoid untoward diagnostic delays of subtler component features of the spectrum, such as an incomplete CDO.

Prevalence, characteristics, and survival of children with esophageal atresia: A 32-year population-based study including 1,417,724 consecutive newborns.

BACKGROUND: Esophageal atresia (EA) is a congenital malformation of the upper gastrointestinal tract with an estimated prevalence varying from 1 in 2500 to 1 in 4500 births. The aim of this study was to describe the epidemiology of EA between 1981 and 2012 and evaluate patients' survival. METHODS: This study used data from a population-based Italian Congenital Malformation Registry. The survival status was ascertained by linking the registry records, vital records and the regional registries of patients. Kaplan-Meier methods were used to estimate survival probabilities up to 25 years and Cox proportional hazards regression was used to evaluate factors that affected survival. RESULTS: A total of 407 cases of EA were identified among 1,417,724 total births. After the exclusion of cases with chromosomal anomalies, 49.9% of the patients presented with at least one associated congenital anomaly. The 25-year survival probability was 85.1% (95% confidence interval [CI], 80.8-89.4), with most deaths occurring during the first months of life. Patients' characteristics associated with decreased survival probability were low birth weight (hazard ratio, 3.7; 95% CI, 1.7-8.3) and presence of additional major defects (hazard ratio, 2.8; 95% CI, 1.3-6.0). A significant improvement in survival over the decades was observed for patients with nonisolated EA. CONCLUSION: This study detected a significant improvement in survival of individuals with EA over the past decades and identified the strongest predictors of mortality. These results will be important for the planning of the clinical management and formulation of prognosis when EA is diagnosed in a newborn.

Anti-Glypican 3, a Novel Ancillary Maker in the Histological Assessment of Hirschsprung's Disease.

OBJECTIVES: Hirschsprung's disease (HSCR) results from a malformation of the enteric nervous system. A congenital absence of intrinsic ganglion cells from the distal rectum and a variable length of the contiguous bowel is the required diagnostic feature of Hirschsprung's disease and total colonic aganglionosis (TCA). We evaluated the utility of a monoclonal antibody directed against glypican 3 (GPC-3), a membrane bound protein involved in regulation of the signaling of Wingless-types (WNTs), Hedgehogs (Hh), Fibroblast Growth Factors (FGFs), and Bone Morphogenetic Proteins (BMPs), in the detection of ganglion cells in formalin-fixed, paraffin-embedded tissue sections. METHODS: The presence/absence of ganglion cells was evaluated retrospectively by immunohistochemical staining for calretinin and GPC-3 in tissue specimens; a total of 15 patients who underwent colectomy (total or sub-total) for histologically proven aganglionosis (14 HSCR, 1 TCA) and 5 rectal suction biopsies (4HSCR-B, 1 TCA-B) were considered. Of the 20 considered cases, a total of 60 tissue specimens (3 for each patient) were selected. A total of 30 additional normal (N) colonic mucosa biopsy samples were also included. RESULTS: GPC-3 constantly identified ganglion cell bodies in all but 2 normal biopsies (with normal presentation of ganglion cells on hematoxylin and eosin (H&E) stain), and was negative in all 60 aganglionotic biopsies; these results were reflective of calretinin staining pattern. CONCLUSIONS: The present study indicates that monoclonal anti-GPC-3 might prove to be useful immunohistochemical marker in the identification of ganglion cells in paraffin-embedded rectal tissue specimens and suction biopsies. Further studies in larger series will contribute to demonstrate its utility as an ancillary marker in the histological assessment of HSCR aganglionosis.

Renal transplantation in children weighing <15 kg: does concomitant lower urinary tract dysfunction influence the outcome?

BACKGROUND: We reviewed our experience with renal transplantation (RTx) in children weighing <15 kg to determine if the presence of lower urinary tract dysfunction (LUTD) influenced the outcome. METHODS: Between 1987 and 2012, 68 RTx were performed in patients weighing less than 15 kg, including 17 with associated LUTD and 51 without. We detailed the lower urinary tract management in these patients, and compared graft survival rates and estimated clearance 12 and 60 months after RTx between groups. RESULTS: None of the patients without LUTD required any lower urinary tract surgery vs 8 out of 17 (47 %) with LUTD (p = 0.0001). The latter included a temporary incontinent urinary diversion in 5 cases (29 %), namely 2 vesicostomies and 3 cutaneous ureterostomies. After comparable follow-ups, there was no difference in patient survival, graft survival, and glomerular filtration rates between groups. CONCLUSIONS: Provided that there is appropriate bladder management, a concomitant LUTD does not adversely influence the outcome of RTx in patients weighing less than 15 kg. However, 50 % of our patients required lower urinary tract reconstruction and, in 30 %, a temporary incontinent urinary diversion was placed at RTx, since lower urinary tract function could not be assessed reliably, the patient was not collaborative enough to be involved in a voiding program, and/or the RTx was prioritized.

Lymphocele after pediatric kidney transplantation: incidence and risk factors.

Lymphocele is a well-known postoperative complication after kidney transplantation. The aim of this study was to analyze time trend incidence, risk factors, and outcome of post-transplant lymphocele in a large pediatric cohort. This is a retrospective single institution review of 241 pediatric kidney transplants performed from 2000 to 2013. Etiology of end-stage renal disease, recipient age and gender, transplant year, BMI percentile for age, type of dialysis, living/non-living related donor, acute rejection, and multiple transplantations were analyzed in association with lymphocele formation. Fourteen of 241 (5.81%) children developed a postoperative lymphocele. There has been a reduction in the incidence of lymphocele after 2006 (3.22% vs. 8.55%, p < 0.05). Significant risk factors for lymphocele were older age (≥11 yr), transplant before 2006, male gender, BMI percentile for age ≥95%, and multiple transplantations (p < 0.05). The one-yr graft survival was significantly reduced in the group with lymphocele compared with control (81.2% vs. 92.51%, p < 0.04). This is the first pediatric report showing the following risk factors associated with post-transplant lymphocele: age ≥11 yr, male gender, BMI for age ≥95%, and multiple transplantations. A lymphocele can contribute to graft loss in the first-year post-transplant.

Congenital Pulmonary Airway Malformation in Preterm Infants: A Case Report and Review of the Literature.

Congenital pulmonary airway malformations (CPAMs) represent a well-known cluster of rare lung malformations affecting 1 in 2500 live births. The natural history of many CPAMs is to increase their size in the second trimester, reach a plateau, and, in about 50% of cases, regress and to become barely detectable during the third trimester. Little is known about cases of affected neonates born prematurely: only six cases are described in the literature, recording different conduct and outcomes. Herein, we report the case of a very low birth weight infant born at GW 28 without antenatal findings and presenting at birth with severe respiratory distress, requiring ventilation. Chest X-rays and a CT scan showed the presence of a solid mass in the left lung. An initial conservative approach was adopted as the baby gained respiratory stability within the first days of life. Routine ultrasound (US) showed a progressive reduction of the lesion, mimicking the process of involution that CPAM can exhibit during late gestation. The rarity of the condition does not allow the formulation of any suggestions regarding one type of management over the other. An initial conservative approach seems to be appropriate with regards to the outcome and possible intra- and post-operative complications.

European Reference Network eUROGEN Guidelines on the Management of Anorectal Malformations, Part II: Treatment.

INTRODUCTION: Anorectal malformations (ARMs) are rare birth defects affecting the anorectum and oftentimes the genitourinary region. The management of ARM patients is complex and requires highly specialized surgical and medical care. The European Reference Network eUROGEN for rare and complex urogenital conditions aimed to develop comprehensive guidelines for the management of ARM applicable on a European level. METHODS: The Dutch Quality Standard for ARM served as the basis for the development of guidelines. Literature was searched in Medline, Embase, and Cochrane. The ADAPTE method was utilized to incorporate the newest available evidence. A panel of 15 experts from seven European countries assessed currency, acceptability, and applicability of recommendations. Recommendations from the Dutch Quality Standard were adapted, adopted, or rejected and recommendations were formed considering the current evidence, expert opinion, and the European context. RESULTS: Surgical and medical treatment of ARM, postoperative instructions, toilet training, and management of fecal and urinary incontinence were addressed. Seven new studies were identified. The panel adapted 23 recommendations, adopted 3, and developed 8 de novo. The overall level of newly found evidence was considered low. CONCLUSION: Treatment of ARM patients requires a multidisciplinary team and expertise about anatomical and surgical aspects of the disease, as well as long-term follow-up. This guideline offers recommendations for surgical and medical treatment of ARM and associated complications, according to the best available evidence and applicable on a European level.

ERN eUROGEN Guidelines on the Management of Anorectal Malformations Part III: Lifelong Follow-up and Transition of Care.

INTRODUCTION: Anorectal malformations (ARMs) are complex congenital anomalies of the anorectal region, oftentimes also affecting the genitourinary system. Although successful surgical correction can often be achieved in the neonatal period, many children will experience functional problems in the long term. The European Reference Network for rare and complex urogenital conditions (eUROGEN) assembled a panel of experts to address these challenges and develop comprehensive guidelines for the management of ARM. METHODS: The Dutch Quality Standard for ARM served as the foundation for the development of guidelines applicable on a European level. Literature was searched in Medline, Embase, and Cochrane. The ADAPTE method was utilized to incorporate the newest available evidence. A panel of 15 experts from 7 European countries assessed currency, acceptability, and applicability of recommendations. Recommendations from the Dutch Quality Standard were adapted, adopted, or rejected and recommendations were formed considering the current evidence and/or expert consensus. RESULTS: Lifelong follow-up, integration, and transition of care were assessed. A total of eight new studies were identified. The panel adapted 18 recommendations, adopted 6, and developed 6 de novo. Overall, the level of evidence was considered low. CONCLUSION: Successful lifelong follow-up and transition of care require a dedicated team of pediatric and adult specialist and an individually tailored patient-centered approach. This guideline summarizes the best available evidence on follow-up of ARM patients and provides guidance for the development of structured transition programs.

ERN eUROGEN Guidelines on the Management of Anorectal Malformations, Part IV: Organization of Care and Communication between Providers.

INTRODUCTION: Being born with an anorectal malformation (ARM) can have profound and lifelong implications for patients and parents. Organization of care and communication between health care providers is an overlooked area of patient care. The European Reference Network eUROGEN for rare and complex urogenital conditions assembled a panel of experts to address these challenges and develop comprehensive guidelines for the management of ARM. METHODS: The Dutch Quality Standard for ARM served as the basis for the development of guidelines. Literature was searched in Medline, Embase, and Cochrane. The ADAPTE method was utilized to incorporate the newest available evidence. A panel of 15 experts from seven European countries assessed currency, acceptability, and applicability of recommendations. Recommendations from the Dutch Quality Standard were adapted, adopted, or rejected and recommendations were formed considering all available evidence, expert consensus, and the European context. RESULTS: Aspects pertaining to organization of care, patient/parent/health care provider communication, and referral and collaboration between providers caring for ARM patients were assessed. Two new studies were identified. In total, the panel adapted 12 recommendations, adopted 7, and developed 2 de novo. The overall level of newly found evidence was considered low and most recommendations were based on expert opinion. CONCLUSION: Collaborative care and organization of care are gaining importance in the field of ARM. This guideline gives practical guidance on how to achieve better communication and collaboration between all involved parties, applicable at the European level.

ERN eUROGEN Guidelines on the Management of Anorectal Malformations Part I: Diagnostics.

INTRODUCTION: Anorectal malformations (ARMs) are rare congenital anomalies that involve the anus, rectum, and oftentimes the genitourinary tract. The management of ARM patients is complex, and many controversies exist. To address this issue, the European Reference Network eUROGEN for rare and complex urogenital conditions aimed to develop comprehensive guidelines for the management of ARM. METHODS: The Dutch Quality Standard for ARM served as the basis for the development of guidelines applicable on a European level. Literature was searched in Medline, Embase, and Cochrane. The ADAPTE method was utilized to incorporate the newest available evidence. A panel of 15 experts from 7 European countries assessed currency, acceptability, and applicability of recommendations. Recommendations from the Dutch Quality Standard were adapted, adopted, or rejected, and recommendations were formed considering current evidence and/or expert consensus. RESULTS: Prenatal and neonatal diagnostic workup as well as postsurgical follow-up of anorectal, genitourinary tract, and neurologic system were reviewed. Seven new studies were identified. The panel adapted 13 recommendations, adopted 7, and developed 8 de novo. The availability of high-quality evidence was limited, and most recommendations were based on retrospective studies, case series, or expert opinion. CONCLUSION: Patients with ARM and their families require highly specialized and comprehensive care from the prenatal period to adulthood. This guideline provides recommendations for a comprehensive diagnostic workup of children with ARM throughout their life that is applicable on a European level.

Influence of Diet on Bowel Function and Abdominal Symptoms in Children and Adolescents with Hirschsprung Disease-A Multinational Patient-Reported Outcome Survey.

Introduction: This study aimed to understand the influence of diet and nutrition items on gastrointestinal symptoms in patients with Hirschsprung Disease (HD). Method: An online questionnaire was created to obtain patient-reported outcomes using the multinational Holistic Care in Hirschsprung Disease Network. This was distributed in Dutch, English, German, Italian, Polish, and Swedish via patient associations. Information on demographics, the extension of disease, current diet, and the influence of food ingredients on bowel function were obtained. Results: In total, 563 questionnaires were answered by parents or patients themselves. The length of the aganglionic segment was short in 33%, long in 45%, total colonic aganglionosis (TCA) in 11%, and involved the small intestine in 10%. Overall, 90% reported following a mixed diet, and 31% reported taking probiotics, with twice as many patients taking probiotics in the TCA group compared to standard HD. Mealtimes and behaviours around eating were affected by 61%, while 77% had established food items that worsened symptoms, and of these, 80% stated that they had worked these items out themselves. A high-fibre diet was followed by 24% and 18% a low-fibre diet. Symptoms were reported, particularly from dairy in 30%, fruits in 39%, pulses in 54%, and sugar in 48%. Conclusions: This first multinational survey on diet and bowel function in HD reports an association between certain dietary items with gastrointestinal symptoms. This study can support an improved understanding of the interaction between food items and bowel function in children with HD. We suggest a multidisciplinary approach to balance dietary exclusions and support adequate growth, preventing nutrition deficiencies and enhancing quality of life.

Diagnosis and Management of Congenital H-Type Tracheoesophageal Fistula: Results of a National Survey.

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.
