Management of patients on anticoagulant or antiplatelet therapy undergoing endoscopy presents a balance of risks between haemorrhage due to the procedure, and thrombosis due to discontinuation of antithrombotic therapy. Haemorrhage is usually controllable endoscopically, but thrombosis could, on occasion, result in myocardial infarction or stroke, with permanent disability or death. For elective procedures, there is adequate time to plan best management of antithrombotic therapy. International guidelines have been published, but recommendations are based on limited evidence and consultation with appropriate medical specialists, and the patient is important...

Anastomotic leak in the gastrointestinal tract is one of the most important complications of resection. They are the main cause of reoperation, their occurrence worsens the prognosis of the patient, increasing the proportion of direct mortality, as well as being a significant risk factor for recurrence of cancer. The risk of leaks within the gastrointestinal tract is greatly varied, depending on the location and extent of the resection, but also on patient, disease or a surgical procedure, including surgeon...

Drug eluting devices have greatly evolved during past years to become fundamental products of great marketing importance in the biomedical field. There is currently a large diversity of highly specialized devices for specific applications, making the development of these devices an exciting field of research. The replacement of the former bare metal devices by devices loaded with drugs allowed the sustained and controlled release of drugs, to achieve the desired local therapeutic concentration of drug. The newer devices have been "engineered" with surfaces containing micro- and nanoscale features in a well-controlled manner, that have shown to significantly affect cellular and subcellular function of various biological systems...

Aortoenteric fistulae are life-threatening conditions characterized by abnormal communications between the aorta and gastrointestinal tract. Aortoenteric fistulae may be characterized by the triad of bleeding, abdominal pain, or a pulsatile abdominal mass. Although hemorrhage is the most common presentation, it does not always occur; thus, patients may present with nonspecific symptoms. Computed tomography angiography findings suggestive of aortoenteric fistulae include ectopic gas within or adjacent to the aorta, discontinuity of the aortic wall, bowel wall thickening, and extravasation of contrast into the bowel...

BACKGROUND: Patients with coronary artery disease (CAD) treated with stents require dual antiplatelet therapy (DAPT). For cirrhotics, who often have varices and coagulopathy, it is not clear if the risk of gastrointestinal bleeding (GIB) should preclude use of DAPT. AIM: To compare GIB and mortality rates in cirrhotics with CAD treated medically or with stents. METHODS: Using institutional databases, we identified patients with cirrhosis and CAD treated with stents or medical therapy between January 2000-September 2015...

An 18-year-old male patient with a history of atopy and intermittent dysphagia for solids, presented to the emergency department with sudden onset total dysphagia followed by hematemesis, after ingesting an ibuprofen tablet. Urgent upper gastrointestinal endoscopy revealed a deep laceration just above the tablet impacted in the distal esophagus. Abdominal CT-scan confirmed the suspicion of an esophageal perforation. The impacted tablet was broken up with biopsy forceps, and a covered metallic stent (Hanarostent® 60/100x20/26mm) was placed across the cardia effectively excluding the fistula...

BACKGROUND Acute coronary syndrome (ACS) can present with atypical chest pain or symptoms not attributed to heart disease, such as indigestion. Hiccups, a benign and self-limited condition, can become persistent or intractable with overlooked underlying etiology. There are various causes of protracted hiccups, including metabolic abnormalities, psychogenic disorders, malignancy, central nervous system pathology, medications, pulmonary disorders, or gastrointestinal etiologies. It is rarely attributed to cardiac disease...

Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy...

BACKGROUND: Post-surgical anastomotic leaks often require a re-intervention, are associated with a definite morbidity and mortality, and with relevant costs. We described a large series of patients with different post-surgical leaks involving the gastrointestinal tract managed with endoscopy as initial approach. METHODS: This was a retrospective analysis of prospectively collected cases with anastomotic leaks managed with different endoscopic approaches (with surgical or radiological drainage when needed) in two endoscopic centres during 5 years...

The failure rate of endoscopic retrograde cholangiopancreatography for biliary cannulation is approximately 6%-7% in cases of obstructive jaundice. Percutaneous transhepatic biliary drainage (PTBD) is the procedure of choice in such cases. Endoscopic ultrasound-guided biliary drainage (EGBD) is a novel technique that allows biliary drainage by echoendoscopy and fluoroscopy using a stent from the biliary tree to the gastrointestinal tract. Information in PubMed, Scopus, clinicaltrials.gov and Cochrane review were analyzed to obtain studies comparing EGBD and PTBD...

We describe the case of a patient successfully reconstructed with laparoscopic retrosternal gastric pull-up after esophagectomy for unresectable posterior mediastinal inflammatory myofibroblastic tumor, eroding into the esophagus and compressing the airways. A partial esophagectomy with esophagostomy was performed for treatment of esophageal pleural fistula and empyema, while the airways were managed with the placement of an endobronchial stent. Gastrointestinal reconstruction was performed using a laparoscopic approach to create a retrosternal tunnel for gastric conduit pull-up and cervical anastomosis...

Endoscopic ultrasound (EUS) offers access to many intra-abdominal vessels that until now have only been accessible to the surgeon and interventional radiologist. In addition to assisting with diagnostics, this unique access offers the potential for therapeutic intervention for a host of indications. To date, this has had the most clinical impact in the treatment of gastroesophageal varices, with EUS-guided coil and glue application growing in use worldwide. Although randomised controlled trial data is lacking, we discuss the growing body of literature behind EUS-guided therapy in the management of varices...

BACKGROUND: With recent advancements in endoscopy, self-expandable metal stents (SEMS) have been used to treat gastrointestinal leaks, perforations, and strictures. Stent migration frequently complicates management and often requires additional treatments to reach resolution. Our study aimed to determine predictive factors for stent migration. METHODS: Consecutive procedures involving SEMS placed with and without fixation after upper gastrointestinal surgery between 2009 and 2014 were retrospectively reviewed...

INTRODUCTION: Although dual antiplatelet therapy (DAPT) is routinely given to patients after percutaneous coronary intervention (PCI) with stenting, the optimal duration is unknown. Recent evidence indicates there may be benefits in extending the duration beyond 12 months but such decisions may increase the risk of bleeding. Our objective is to provide a comprehensive overview of the literature for clinicians and policymakers via an umbrella review assessing the optimal duration of DAPT...

Portal vein aneurysm (PVA) is a rare vascular dilatation of the portal vein. It is a rare vascular anomaly representing less than 3% of all visceral aneurysms and is not well understood. Usually, PVA are incidental findings, are asymptomatic, and clinical symptoms are proportionally related to size. Patients present with nonspecific epigastric pain or gastrointestinal bleeding with underlying portal hypertension. PVA may be associated with various complications such as biliary tract compression, portal vein thrombosis/rupture, duodenal compression, gastrointestinal bleeding, and inferior vena cava obstruction...
