Esophageal duplication and congenital esophageal stenosis

Multidisciplinary Surgical Care for a Cervical Esophageal Duplication Cyst

We present a case of a three-month-old male who presented with a cervical esophageal duplication cyst requiring early surgical intervention. The patient presented with feeding difficulties, poor weight gain, and respiratory distress. Due to the position of the cervical esophageal duplication cyst and airway compression, this unique case required a multidisciplinary surgical approach involving both otolaryngology and cardiothoracic surgery.

Oesophageal injury mimicking a tubular congenital oesophageal duplication-a diagnostic dilemma: a case report

Intramural oesophageal dissection (IED) is an uncommon condition in newborns marked by the separation of the mucosal and submucosal layers of the oesophageal wall, both transversely and longitudinally, which may or may not involve perforation. A neonate presented at 26 h of life with poor respiratory effort and lethargy. She was intubated and was put on mechanical ventilation. Radiograph of the neonate suggested malpositioned endotracheal tube. The fluoroscopic dye-study indicated gastroesophageal oesophageal reflux disease and nothing significant. On limited CT contrast study of thorax, a tubular structure was seen running just parallel to the oesophagus extending from the T2 to the T9 levels. Possibilities of a oesophageal duplication/IED were considered. The neonate underwent an endoscopy and gastrostomy on day of life (DOL) 9. On follow up at 3 months a repeat limited CT study was done with instillation of water-soluble contrast. The previously seen tubular structure running parallel to the oesophagus was no longer seen. This finding suggested a healed IED. This case report emphasizes the significance of multimodality imaging in the diagnosis of this condition.

Surgical esophageal diseases in children

Pediatric age esophageal diseases are rare and complex clinical conditions. Treatment options should be individually determined for the patient. The advances in the follow-up and treatment process is the most important reason for the increase in survival time, particularly for congenital pediatric surgical diseases. This study aimed to evaluate the general characteristics of pediatric surgical esophageal diseases in light of the literature.

Reconstruction of Adult Tubular Esophageal Duplication with Supraclavicular Artery Island Flap: A Rare Case Presentation

Adult esophageal duplication (ED) is a rare congenital anomaly that is rarely encountered in clinical practice. There have been only a few reported cases of adult tubular esophageal duplication. A patient presented with symptoms of odynophagia and dysphagia. Upon examination, gastroscopy and X-ray contrast imaging revealed the formation of a fistula in the upper esophagus that connected to a sinus tract running along the esophagus. After managing the initial infection, an open surgery was performed. The esophageal tubular duplication was removed and the defect was reconstructed using a supraclavicular artery island (SAI) flap. The post-operative recovery was uneventful and the patient's odynophagia and dysphagia were relieved. In conclusion, ED can be effectively diagnosed through esophagogram and gastroscopy. Surgical excision is currently the preferred treatment option, and the use of the SAI flap technique shows great promise in reconstructing the esophageal defect after surgery.

Tubular Duplication of the Esophagus in a Newborn, Treated by Thoracoscopy

We present a case of tubular esophageal duplication in a 3-day-old female newborn (38 weeks, 2,500 g) without concomitant abnormal development. Esophageal duplication was diagnosed based on the clinical picture, direct laryngoscopy, esophagography and computed tomography. The duplicated esophagus was resected by thoracoscopy leaving the orthotopic esophagus in place. Isolation from the pharynx was performed via a separate cervical incision. After a follow-up period of 20 months, the child returned to normal growth and development.

Management and clinical outcomes of congenital esophageal stenosis in pediatric patients: Experience of a tertiary referral center

PURPOSE

This study aimed to retrospectively investigate congenital esophageal stenosis (CES) cases managed at our institution using a non-aggressive strategy based on a step-up approach from esophageal balloon dilatations to surgery.

METHODS

Patients' charts with CES managed in a tertiary pediatric surgery department were retrospectively evaluated. Demographic characteristics, clinical features, pH-monitoring, imaging, and esophagoscopy results were recorded together with their treatments and outcomes.

RESULTS

Nineteen patients, confirmed with radiologic and endoscopic investigations, were managed. Complete symptom resolution was achieved in 14 patients by a median of five (2-15) recurrent esophageal balloon dilatations lasting for 7.5 (2-108) months. Two more patients, after 7 and 15 dilatations, had mild dysphagia, not interfering with their daily living. One patient, in whom the initial dilatation attempt with 3 atm was unsuccessful, and two patients with persistent symptoms and growth retardation despite ongoing dilatation treatment, underwent surgery. After 48 (12-132) months of follow-up, 17 patients were symptom-free.

CONCLUSION

Conservative treatment with esophageal balloon dilatations is an efficient and reliable modality that can be used as a first-line treatment in CES. Surgical treatment option should be used when dilatation attempt is unsuccessful, or symptoms and growth retardation persist despite dilatation treatment.

Congenital oesophageal stenosis in oesophageal atresia: underrecognised and often missed?

PURPOSE

Congenital oesophageal stenosis (COS) is characterised by an intrinsic oesophageal narrowing that is present, but not necessarily symptomatic at birth. Small studies report an association of COS with oesophageal atresia (OA) in up to 14% of OA cases. Although OA is usually appreciated shortly after birth, the diagnosis of a concomitant COS is frequently delayed. This risk may be increased with the current movement away from routine postoperative upper gastrointestinal (GI) contrast study following OA repair. We performed a systematic review of the literature to assess the timing of diagnosis of COS in patients with COS and OA and how this impacted on patient outcomes.

METHODS

A systematic review in accordance with PRISMA guidelines was undertaken. Only patients with OA associated with COS were included. Delayed diagnosis was defined as presentation > 1 month of age.

RESULTS

14 full-text studies with a total of 131 patients were included. Diagnosis of COS was delayed in 62/131 (47%) patients. These children presented with symptoms of dysphagia and aspiration at a median age of 13.5 months (IQR 7-30 months). In total, 18/131 patients were identified at the initial operation, due to difficulty passing a tube distally into the stomach. The data on timing of contrast studies were provided in 60/131 (46%) patients. A routine postoperative contrast study was performed in 39/60 (65%) of these, of which COS was identified immediately in 28/39 (72%). A diagnosis of COS could also be made on retrospective review of the early contrast study in a further 6/39 patients, giving an overall sensitivity of 87%.

CONCLUSION

The association of COS and OA may be underrecognised and diagnosis delayed if routine contrast study is not performed. Contrast studies, performed in the neonatal period are effective at detecting a concomitant COS (sensitivity > 87%). This review supports routine early contrast study after OA repair with specific consideration of the presence of COS.

Esophageal Dysphagia in Children: State of the Art and Proposal for a Symptom-Based Diagnostic Approach

Pediatric esophageal dysphagia (PED) is an infrequent condition that can be determined by a large number of disorders. The etiologic diagnosis is challenging due to overlapping clinical phenotypes and to the absence of pediatric diagnostic guidelines. This review aims to summarize the most relevant causes of ED during childhood, highlight the clinical scenarios of PED presentation and discuss the indications of available diagnostic tools. Available information supports that PED should always be investigated as it can underlie life-threatening conditions (e.g., foreign body ingestion, mediastinal tumors), represent the complication of benign disorders (e.g., peptic stenosis) or constitute the manifestation of organic diseases (e.g., eosinophilic esophagitis, achalasia). Therefore, the diagnosis of functional PED should be made only after excluding mucosal, structural, or motility esophageal abnormalities. Several clinical features may contribute to the diagnosis of PED. Among the latter, we identified several clinical key elements, relevant complementary-symptoms and predisposing factors, and organized them in a multi-level, hierarchical, circle diagram able to guide the clinician through the diagnostic work-up of PED. The most appropriate investigational method(s) should be chosen based on the diagnostic hypothesis: esophagogastroduodenoscopy has highest diagnostic yield for mucosal disorders, barium swallow has greater sensitivity in detecting achalasia and structural abnormalities, chest CT/MR inform on the mediastinum, manometry is most sensitive in detecting motility disorders, while pH-MII measures gastroesophageal reflux. Further studies are needed to define the epidemiology of PED, determine the prevalence of individual underlying etiologies, and assess the diagnostic value of investigational methods as to develop a reliable diagnostic algorithm.

Esophagus-Like Bronchus: A Noncommunicating Bronchopulmonary Foregut Malformation

We describe a previously unreported bronchopulmonary foregut malformation wherein a segment of a bronchus of the lower lobe of the left lung in a 4-year-old girl was entirely esophageal in structure. No communication was identified between the tracheobronchial tree and the esophagus by radiologic examination or at surgery. The esophagus-like bronchus was associated with an adjacent atretic bronchus and a downstream cavity in the lower lobe of the left lung. The child sought clinical attention because of recurrent pulmonary infections localized to the lower lobe of the lung. We posit that this esophagus-like bronchus is a novel noncommunicating bronchopulmonary foregut malformation.

Laparoscopic-Assisted Longitudinal Incision and Transverse Anastomosis: A Novel Surgical Approach for Treatment of Esophageal Stenosis Caused by Tracheobronchial Remnants

Purpose: To review the treatment of lower congenital esophageal stenosis caused by tracheobronchial remnants (TBR) and to introduce a novel technical approach through laparoscopic surgery. Methods: Patients with TBR who underwent surgery in our single-center from January 2016 to December 2019 were enrolled. Resection of cartilage with stenotic esophageal segment and end-to-end anastomosis was the traditional surgery. Since 2018, longitudinal incision with partial resection of cartilage loop in the anterior esophageal wall and the transverse suture was conducted endoscopically. We reviewed the treatment, followed-up with these patients, and discussed the new procedure's preponderance. Main Results: Thirteen patients underwent surgery and were followed-up for 0.5-45 months (M = 13) after surgery. Twelve patients showed good physical development with a regular diet. One patient, who was 2 weeks after the surgery, was fed by a soft diet and regularly followed-up at our clinic. In 13 cases, five patients underwent traditional laparotomy with pyloroplasty. Two patients who went through anastomotic leakage were cured by drainage and conservative treatments. Anastomotic stricture that occurred in two cases was improved by one-time of dilation. The administration time of parenteral nutrition (PN) was 9.0 ± 1.4 days. The length of hospitalization was 36.6 ± 5.2 days. Eight cases underwent the new surgical approach through laparoscopy or thoracoscopy. Pyloroplasty was avoided since the vagal close to the posterior wall of the esophagus was protected. Gastric motility disorder did not occur as expected. No leakage occurred postoperatively. The anastomotic stricture was found in six cases and improved after one to five times of dilations. The length of hospitalization dropped to 18.6 ± 6.9 days significantly (P < .001). Conclusions: Longitudinal incision and transverse anastomosis of the anterior wall of the esophagus with partial resection of cartilage without pyloroplasty through endoscopy is a novel practical surgical approach to treat patients with TBR.

Laparoscopic partial circular myectomy for congenital esophageal stenosis due to tracheobronchial remnant

Congenital esophageal stenosis (CES) is a rare anomaly, and its appropriate management is not well established. This may be the first report describing laparoscopic partial circular myectomy of the esophageal wall in an infant with CES caused by tracheobronchial remnant (TBR). The narrow segment of the esophagus was laparoscopically detected 1 cm above the esophagogastric junction because the segment was whiter and narrower than the other parts of the esophagus. The narrow segment was approximately 1.5 cm in length. Partial anterior 270° circular muscle layers were dissected using hook electrocautery. Small cartilage-like tissues were identified during the procedure. The muscular layers of both ends were interruptedly sutured. Intraoperative complications were not detected. After undergoing balloon dilation for slight residual stenosis, the patient could eat solid foods without vomiting. Laparoscopic partial circular myectomy is safe and effective for short-segment lower esophageal stenosis in patients with CES caused by TBR.
