BACKGROUND: and Importance: Esophageal injury is a severe surgical complication of a transsternal approach to the high thoracic vertebral metastasis, which can result in mediastinitis and life-threatening consequences. A covered stent can be placed in the esophagus to prevent mediastinal leakage. However, tracheomalacia is a very rare complication following esophageal stenting. CLINICAL PRESENTATION: A 56-year-old man had a pathologic fracture of the T3 vertebral body with spinal cord compression, myelopathy, and neurogenic bladder...

In this paper, I reviewed the emerging field of endoscopic surgery and present data supporting the contention that endoscopy can now be used to treat many foregut diseases that have been traditionally treated surgically. Within each topic, the content will progress as follows: "lessons learned", "technical considerations" and "future opportunities". Lessons learned will provide a brief background and update on the most current literature. Technical considerations will include my personal experience, including tips and tricks that I have learned over the years...

We report a case of bronchial artery aneurysm (BAA) successfully treated with a combination of transcatheter embolization and stent graft. A 50-year-old woman was referred to our hospital for further examination of a hemispherical bulging lesion on the middle esophagus detected by gastroscopy. Computed tomography (CT) revealed BAA with a 15 mm-diameter arising from the descending aorta on the left side of the esophagus. We performed transcatheter embolization combined with a stent graft because of a short neck...

INTRODUCTION: Post-oesophagectomy leakage occurs in 1-30% of cases as a significant factor in postoperative morbidity and mortality, accounting for 40% of postoperative deaths. Endoscopic vacuum therapy (EVAC) is, besides stent therapy, clips and surgical therapy, a new endoscopic thera-peutic modality. CASE REPORT: A 72-year-old polymorbid female patient with Siewert type II adenocarcinoma of the distal esophagus (T1b, N0, M0) was indicated for resection of the upper stomach and lower thoracic esophagus from laparotomy and thoracotomy with reconstruction using double-stapling anastomosis...

Objective: To investigate the dosimetric distribution characteristics of (125)I seed stents with different seed spacing, diameter and length, as well as different (125)I seed activity. The dosimetry table of (125)I seed esophageal stent was derived to provide dosimetry for its clinical application. Methods: The self-expanding coated esophagus stent was designed to carry radioactive (125)I seeds with different length, diameter and seed spacing. A cylindrical organic glass model (Thickness 0.8 cm, diameter 20 cm, height 20 cm) was fixed vertically to a cylindrical organic glass containing a solid paraffin (analytical pure) solution...

Palliation therapy for dysphagia using esophageal stents is the current treatment of choice for those patients with inoperable esophageal malignancies. However, the metallic and plastic stents currently used in the clinical setting may cause complications, such as tumor ingrowth and stent migration into the stomach. To effectively reduce/overcome these complications, we designed a tubular, flexible polymer stent with spirals. The parameters of the spirals were computationally optimized by using a finite element analysis...

Caustic injury of the esophagus is a problematic condition challenging endoscopists worldwide. Although the caustic agents and motives are different among countries and age groups, endoscopy still plays an invaluable role in diagnosis and treatment. Endoscopy can determine the severity of caustic ingestion which is of great importance in choosing appropriate treatment. However, some aspects of endoscopy in diagnosis of caustic injury remain controversial. Whether or not all patients need endoscopy, when to perform endoscopy and how to assess the severity are just some examples of these controversies...

BACKGROUND: Current guidelines favour the use of bleeding stents over balloon tamponade (BT) for refractory variceal bleeding (VB) from oesophageal varices. However, data on the efficacy and safety of self-expandable metal SX-ELLA Danis stents (SEMS) are limited. METHODS: Cirrhotic patients receiving SEMS for VB at four tertiary care centres were included in this retrospective multicentre study. Rates of failure-to-control bleeding (within 5 days) and bleeding-related mortality (6 weeks) were assessed...

A 42-year-old man presented to the emergency department with gunshot wound to left upper back over the scapula and palpable bullet over the right supraclavicular fossa. The patient had a left-sided needle thoracostomy in the field. He was tachypneic and tachycardiac but normortensive on arrival. Due to the patient being in respiratory distress, he was orotracheally intubated. On examination, he was found to have a moderate left pneumothorax with mild mediastinal shift. He had a left closed tube thoracostomy placed...

Boerhaave syndrome refers to a spontaneous perforation of the esophagus that results from severe straining or vomiting. This uncommon situation may lead to serious outcome with chemical mediastinitis, and is associated with high morbidity and mortality. Surgery, although associated with high morbidity and mortality remains the treatment of choice, whereas endoscopic management with stent placement is preserved to treat inoperable patients. Removal of the stent is generally recommended after 4-6 weeks. We report a case of an elderly patient who presented with a large complicated Boerhaave's mid-esophageal perforation, with a complete recovery after a 3-month treatment with a long esophageal stent...

Tracheoesophageal fistulas (TEF) are pathologic communications between the esophagus and the trachea or bronchi. The development of a TEF can result from malignant or benign etiologies. A common approach for the treatment of TEFs is the placement of endobronchial and esophageal stents to facilitate healing of the communication. This case report describes the successful treatment of a TEF resulting from calcified mediastinal lymphadenopathy due to a previous Histoplasmosis capsulatum infection. In addition to placement of endobronchial and esophageal stents, the non-healing TEF was treated with ACell (Gentrix® ) decellularized porcine urinary bladder matrix to facilitate complete closure of the fistulous tract...

Current therapeutic strategies are insufficient for suppressing stent-induced restenosis. Here, branched gold nanoparticles (BGNP)-coated self-expandable metallic stents (SEMSs) were developed for a local heat-induced suppression of stent-related tissue hyperplasia. Our polydopamine (PDA) coating on SEMS allowed BGNP crystal growth on the surface of SEMSs. The prepared BGNP-coated SEMS showed effective local heating under near-infrared laser irradiation. The effectiveness of BGNP-coated SEMSs for suppressing stent-related tissue hyperplasia was demonstrated in a rat esophageal model ( n = 52)...

Stent migration, which causes issues in stent therapy for esophageal perforations, can counteract the therapeutic effects and lead to complications. Therefore, techniques to regulate stent migration are important and lead to effective stent therapy. Here, in these cases, we placed a removable fully covered self-expandable metallic stent (FSEMS) in a 52-year-old man with suture failure after surgery to treat Boerhaave syndrome, and in a 53-year-old man with a perforation in the lower esophagus due to acute esophageal necrosis...

OBJECTIVES: Disk battery esophageal retention in children younger than 6 years represents an increasing endoscopic emergency, followed by a relevant risk of life-threatening late complications. Surgical removal after a failed endoscopic approach is rarely reported in the literature. We describe our experience in this scenario. METHODS: Two female asymptomatic patients aged 26 and 29 months presented within 4 hours after a witnessed ingestion of a 2-cm, 3-V lithium battery (CR2032) retained in the cervical esophagus...

Bronchoesophageal and tracheoesophageal fistulas are an uncommon but well-documented complication of Hodgkin lymphoma (HL). To our knowledge, a fistula directly connecting the esophagus with the lung (esophageal-pulmonary fistula) and resulting from HL has not been reported in the literature. We present a case of HL complicated with an esophageal-pulmonary fistula. The early recognition and treatment of an esophageal-pulmonary fistula in patients with HL are imperative since, with appropriate treatment, HL complicated with an aero-esophageal fistula has the same prognosis as those without one, unlike the dismal prognosis in esophageal and lung cancer...

OBJECTIVE: Stenting is one of the major treatments for malignant esophageal cancer. However, stent migration compromises clinical outcomes. A flared end design of the stent diminishes its migration. The goal of this work is to quantitatively characterize stent migration to develop new strategies for better clinical outcomes. METHODS: An esophageal stent with flared ends and a straight counterpart were virtually deployed in an esophagus with asymmetric stricture using the finite element method...

Esophageal perforation constitutes a surgical emergency. Despite its gravity, no single strategy has been described as sufficient to deal with most situations to date. The aim of this study was to assess the etiology, management, and outcome of esophageal perforation over a 28-year period, to characterize optimal treatment options in this severe disease. A retrospective clinical review of all patients treated for esophageal perforation at Ramón y Cajal Hospital between January 1987 and December 2015 was performed (n = 57)...
