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 SEMS. The prepared BGNP-coated SEMS showed effective local heating under near infrared laser irradiation. The effectiveness of BGNP-coated SEMS for suppressing stent-related tissue hyperplasia was demonstrated in a rat esophageal model (n=52)...

PURPOSE: Although surgical resection and graft replacement therapy for thoracic aortic aneurysms has advanced greatly over the last 20 years, significant perioperative morbidity and mortality still occur, particularly in patients considered high risk due to significant coexisting medical illness or previous operations performed for the treatment of intrathoracic disease. CASE REPORT: The case described is that of a patient with a giant (13.8cm) symptomatic descending thoracic aorta (DTA) aneurysm, previously treated endovascularly 15 years ago...

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)...

BACKGROUND: Esophageal perforation is a potentially life-threatening problem if not quickly diagnosed and treated appropriately. Negative pressure wound therapy (NPWT), commercially known as V.A.C.® therapy, was developed in the early 1990 s and is now standard of care for chronic surface wounds, ulcers, and burns. Adapting vacuum sponge therapy for use intraluminally for perforations of the esophagus was first reported in 2008. We report the first pediatric experience on a customized esophageal vacuum assisted closure (EVAC) device for closure of esophageal perforations...

BACKGROUND:  Covered esophageal self-expandable metal stents (SEMSs) are currently used for palliation of malignant dysphagia. The optimal extent of the covering to prevent recurrent obstruction is unknown. Therefore, we aimed to compare fully covered (FC) versus partially covered (PC) SEMSs in patients with incurable malignant esophageal stenosis. METHODS:  In this multicenter randomized controlled trial, 98 incurable patients with dysphagia caused by a malignant stricture of the esophagus or cardia were randomized 1:1 to an FC-SEMS or PC-SEMS...

Endoscopic submucosal dissection or widespread endoscopic resection allow the radical removal of circumferential or near-circumferential neoplastic esophageal lesions. The advantage of these endoscopic methods is mini-invasivity and low risk of major adverse events compared to traditional esophagectomy. The major drawback of these extensive resections is the development of stricture - the risk is 70-80% if more than 75% of the circumference is removed and almost 100% if the whole circumference is removed. Thus, an effective method to prevent post-ER/ESD esophageal stricture would be of major benefit, because treatment of strictures requires multiple sessions of endoscopic dilatation and may carry a risk of perforation...

INTRODUCTION: Complete circular endoscopic (submucosal) resection (CER) performed using the endoscopic submucosal dissection (ESD) technique is burdened with a high incidence of post-operative strictures in the esophagus. The most effective method of preventing them is not known so far; one of the possible methods is to prevent these strictures directly at the site of their formation by covering the defect with a stent. The aim of the study was to find a way to fix a selected biomaterial to a stent, and subsequently, to fix the stent at the CER site to prevent esophageal strictures in an animal model...

BACKGROUND: Esophageal respiratory fistulae are abnormal communications between the esophagus and the respiratory system. They are either congenital or acquired. Most acquired esophageal respiratory fistulae are of the esophageal tracheal and esophageal bronchial type and are caused by infections or malignant neoplasms, whereas esophageal pulmonary fistulae are rare. CASE PRESENTATION: We report a case of a 72-year-old Caucasian man with squamous cell carcinoma of the lung presenting with abrupt-onset dyspnea during localized mediastinal radiotherapy...

Stents and tubes to maintain the patency of the airways are commonly used for malignant obstruction and are occasionally employed in benign disease. Malignant airway obstruction usually results from direct involvement of bronchogenic carcinoma, or by extension of carcinomas occurring in the esophagus or the thyroid. External compression from lymph nodes or metastatic disease from other organs can also cause central airway obstruction. Most malignant airway lesions are surgically inoperable due to advanced disease stage and require multimodality palliation, including stent placement...

BACKGROUND AND AIMS: Esophageal stricture is a common adverse event after endoscopic submucosal dissection (ESD) when it involves the entire circumference of the esophagus. We aimed to assess the effectiveness and safety of endoscopic transplantation of autologous esophageal mucosa in preventing stricture formation after circumferential ESD. METHODS: Nine patients who underwent circumferential ESD for early esophageal cancer were enrolled. After the patients underwent ESD, autologous esophageal mucosal patches were attached to the ulcer surface by using hemoclips and were then fixed with a covered metal mesh stent...

INTRODUCTION: Carotid blowout syndrome (CBS) is a life threatening complication associated with head and neck cancers (HNC) and its treatment. The mortality rate was reported to range from 3% to over 50% in the literature. Direct surgical repair of the ruptured internal carotid artery is often not technically possible due to the difficult anatomy and underlying poor co-morbid status. Endovascular techniques such as coil embolization and stent grafting offer an alternative to surgical ligation with better patient outcomes...

An aberrant right subclavian artery (ARSA) is the most common aortic arch anomaly, but only 19 previous cases of ARSA-esophageal fistula have been reported. Six patients have survived their bleeding episode. We describe the case of a 44-year-old woman who developed massive hemoptysis. Laryngoscopy, bronchoscopy, head and neck angiogram, and median sternotomy did not reveal what was presumed initially to be a tracheoinnominate fistula. Contrasted CT showed an anomalous subclavian artery posterior to the esophagus...

Esophageal perforation may occur spontaneously, iatrogenically or in connection with traumas. Sepsis may develop in connection with mediastinal and pleural exposure in a very short time as a consequence of disintegration of the esophagus. Esophageal perforation is an emergency accompanied with a high level of mortality and morbidity. Rate of mortality for the perforations in the thoracic region is higher than that in the cervical and abdominal regions. Delay in diagnosis and treatment is the most important factor to affect the mortality...

Most procedures in gastrointestinal (GI) surgery require reconstruction with an anastomosis. Depending on the location within the GI tract, the perfusion and comorbidities of the patients there is a risk for anastomotic leakage. In case of peritonitis with sepsis usually a surgical treatment is required. A stable patient can be treated nonoperatively. In the following overview different treatment options of anastomotic leakage after surgery of the GI tract are described. In case of a leakage of an esophagojejunal or esophagogastric anastomosis after resection of the esophagus or stomach endoscopic treatment can be successful using either clip or stent or negative pressure therapy (NPT)...
