BACKGROUND: Malignant dysphagia can result in poor nutritional status with severe weight loss. Rapid relief from dysphagia can be achieved with esophageal self-expanding metal stents (SEMSs), a minimally invasive method. In this study, we evaluated the usefulness of SEMSs for malignant dysphagia. METHODS: Between 2012 and 2015, 119 patients with malignant dysphagia underwent esophageal SEMS insertion with endoscopic assistance. Their demographics and clinical outcomes were collected...

BACKGROUND: Data on the typical time point of occurrence of anastomotic leak (AL) after esophagectomy for esophageal cancer are currently scarce. Therefore, the usefulness of routine radiocontrast agent studies (RRCS) for testing proper healing of the anastomosis after esophagectomy remains unclear. Furthermore, preferred available tools to diagnose postoperative AL and therapeutic options are still under debate. METHODS: We present a retrospective analysis of 328 consecutive patients who underwent esophagectomy for esophageal cancer between 2005 and 2015...

An antitumor drug/esophagus stent combination can palliatively relieve malignant esophageal stricture and exert local chemotherapy to cancer. It is vital for effective treatment of cancer to control drug release and facilitate drug penetration into deep tissue after the combination is placed in the malignant strictured esophagus part. In this study, we firstly designed and prepared a novel antitumor drug/esophagus stent combination: a magnetocaloric nitinol stent coated with a bilayered film that consisted of one ethylene-vinyl acetate copolymer (EVA) layer as drug blocking layer and one EVA layer containing 10% paclitaxel (PTX) and 30% temperature sensitive phase-change fatty alcohol (1-tetradecanol, 1-hexadecanol or 1-octadecanol)...

Two patients with locally advanced squamous cell carcinoma of the mid-esophagus, with esophageal stents in situ, suffered sudden onset of massive hematemesis and hemodynamic instability due to an aortoesophageal fistula. Although their esophageal neoplasms were deemed inoperable and treatment was palliative, the bleeding was successfully stopped with an endovascular aortic stent-graft. They both remained stable with no septic or hemorrhagic complications, and survived for 14 and 16 weeks after the operation...

Tracheal stenosis caused by malignancy is a life-threatening complication. We performed stent therapy in two patients using the AERO™ stent, launched in late 2016 in Japan. One patient presented with stenosis of the trachea due to adenoid cystic carcinoma and the other with stenosis of the trachea due to esophageal cancer. Both patients showed improved symptoms, and no complications were identified. This is the first report of a favorable outcome with the use of this hybrid stent in Japan, and the findings suggest that insertion of the AERO hybrid stent is an effective way to improve patients' quality of life...

BACKGROUND AND STUDY AIMS:  Fixation of an esophageal self-expandable metal stent (SEMS) with an over-the-scope-clip (OTSC) system for a benign stricture to prevent migration has been reported. However, the efficacy of SEMS fixation with an OTSC for malignant esophageal stricture remains unclear. The aim of this retrospective study was to evaluate the feasibility of SEMS fixation with an OTSC for a malignant esophageal stricture. PATIENTS AND METHODS : Twelve patients who underwent esophageal SEMS placement and fixation with an OTSC for a malignant esophageal stricture were included in this retrospective study...

BACKGROUND: Tracheal and bronchial stenosis is a life-threatening condition causing difficulty in breathing and even severe respiratory distress. The silicone tracheobronchial stents were placed using the rigid bronchoscopy into the trachea of severe dyspneic patients and they exhibited symptomatic improvement as well as a rise in the saturation of oxygen. The bronchial stents were applicable to many extensive malignant airway stenosis patients, such as those with esophageal cancer, lung cancer, and laryngeal cancer...

BACKGROUND: Sleeve gastrectomy has become one of the main bariatric procedures over the last few years. This can be explained by the relative simplicity and high effectiveness of this method. Yet, it causes complications as any other method. Staple line leaks are the most frequent ones. According to different sources, this complication may occur with 0-7% frequency. Until 2013, surgery was the only effective treatment method for this complication. However, reoperations considerably increased treatment cost and patient morbidity...

This narrative review aims to evaluate the evidence for the different nutritional approaches employed during neoadjuvant therapy in patients with loco-regional esophageal cancer. Patients with esophageal cancer are often malnourished and difficult to optimise nutritionally. Whilst evidence suggests neoadjuvant therapy can offer a survival advantage, associated toxicity can exacerbate poor nutritional status. There is currently no accepted standard of care regarding optimal nutritional approach.A systematic literature search was undertaken...

BACKGROUND: Endoscopic vacuum-assisted closure (EVAC) therapy is increasingly being used as a new promising method for repairing upper gastrointestinal defects of different etiologies with high success rates. EVAC therapy consists of placing a sponge either within the lumen or within an abscess cavity connected with a nasogastric (NG) tube to a negative pressure system, thus decreasing bacterial contamination and edema and promoting granulation tissue proliferation, thereby gradually decreasing the cavity size until complete closure...

Self-expanding metal stenting is an established treatment modality in the management of esophageal growth and stricture. Reactive tissue ingrowth at the uncovered portion of the self-expanding metal stent (SEMS) anchors it in position, preventing its migration. When removal of such an embedded SEMS is clinically indicated, the procedure of endoscopic retrieval is fraught with serious complications. Temporary deployment of a larger fully covered "rescue" SEMS within the embedded SEMS has been reported to be useful in the extraction of the embedded SEMS...

In the report, we describe a case of refractory benign esophageal strictures from esophageal cancer after an operation for the placement of three partially covered self-expanding metal stents (SEMSs), which were all embedded in the esophageal wall. Using the stent-in-stent technique, the three embedded SEMSs were successfully removed without significant complications. To the best of our knowledge, few cases of the successful removal of multiple embedded esophageal SEMSs have been reported in the literature...

BACKGROUND AND AIMS: Malignant esophagorespiratory fistula (MERF) has been usually managed by the placement of self-expandable metal stent (SEMS) with conflicting results. This study aimed to identify risk factors associated with clinical failure after SEMS placement for the treatment of MERF. METHODS: This was a retrospective analysis of a prospectively maintained database used at a tertiary cancer hospital, with patients treated with SEMS placement for MERF between January 2009 and February 2016...

REVIEW
Sunil Kapur, Chirag Barbhaiya, Thomas Deneke, Gregory F Michaud
Esophageal perforation is a dreaded complication of atrial fibrillation ablation that occurs in 0.1% to 0.25% of atrial fibrillation ablation procedures. Delayed diagnosis is associated with the development of atrial-esophageal fistula (AEF) and increased mortality. The relationship between the esophagus and the left atrial posterior wall is variable, and the esophagus is most susceptible to injury where it is closest to areas of endocardial ablation. Esophageal ulcer seems to precede AEF development, and postablation endoscopy documenting esophageal ulcer may identify patients at higher risk for AEF...

BACKGROUND: The treatment of recurrent esophageal stricture secondary to the ingestion of a caustic agent is an arduous task. Self-expanding esophageal stents may be an alternative to repeated endoscopic esophageal dilations. CASE REPORT: We present the case of a two-year-old male with a severe and long esophageal stricture successfully treated by the combination of dilations and stent placement. After five months of serial pneumatic dilations, three self-expanding nitinol stents internally coated with silicone were introduced through a gastrostomy, covering the entire esophagus...
