Acute upper GI bleeding is a common medical emergency with a hospital mortality of approximately 10%. Non variceal UGI bleeding is the most common cause followed by oesophageal varices. Various rare causes have been described in the literature but there are very few cases of giant left atrium leading to oesophageal erosion and causing upper GI bleeding. We are presenting a case of rheumatic valvular heart disease with giant left atrium who presented in our department with acute upper GI bleeding.

Obesity is a risk factor for a plethora of severe morbidities and premature death. Most supporting evidence comes from observational studies that are prone to chance, bias and confounding. Even data on the protective effects of weight loss from randomized controlled trials will be susceptible to confounding and bias if treatment assignment cannot be masked, which is usually the case with lifestyle and surgical interventions. Thus, whilst obesity is widely considered the major modifiable risk factor for many chronic diseases, its causes and consequences are often difficult to determine...

Histoacryl glue is used increasingly for the treatment of gastric and ectopic varices, and there is experience in its use for oesophageal varices. It is an effective treatment, yet numerous reports of complications have accumulated. This review of the literature describes the technique, explores circulatory and vascular consideration unique to portal hypertension and categorises the complications into: "Embolisation", "local venous thrombosis", "fistulisation and extravascular injection", "ulceration, erosion and extrusion", and "nidus of infection"...

Adverse events can occur during and after the endoscopic resection of upper gastrointestinal lesions. Their incidence can be minimized through the adoption of preventive measures and their final outcomes can be optimized through prompt identification and adequate treatment. In this evidence-based review we describe the risk factors for adverse events, preventive measures to avoid them and their management when they occur. Algorithms of action are also provided. Oesophageal strictures can be prevented with corticosteroids (either locally injected or systemically administered) and treated with endoscopic dilatation...

INTRODUCTION: Barrett's oesophagus (BO), a metaplastic condition affecting the lower oesophagus due to long-standing gastro-oesophageal reflux and chronic inflammation, is a precursor lesion for oesophageal adenocarcinoma (OADC). There is no clinical test to predict which patients with BO will progress to OADC. The British Society of Gastroenterology recommends endoscopic surveillance of patients with BO. Epigenetic changes have been well characterised in the neoplastic progression of ulcerative colitis to colonic carcinoma, another gastrointestinal cancer associated with chronic inflammation...

INTRODUCTION: Perioperative chemotherapy is the gold standard treatment of the resectable gastro-oesophageal adenocarcinoma. However, 70% of patients cannot receive the complete sequence because of a postoperative complication or a decrease in functional and nutritional reserves. Recently, a new concept appeared in digestive surgery: prehabilitation. This interventional process consists of patient preparation, between surgical consultation and surgery, and is based on 3 components: (1) physical management, (2) nutritional care and (3) psychological care...

Non-CG methylation has been associated with stemness regulation in embryonic stem cells. By comparing differentially expressed genes affected by non-CG methylation between tumour and corresponding non-tumour tissues in oesophageal squamous cell carcinoma (OSCC), we find that Integrin α7 (ITGA7) is characterized as a potential cancer stem cell (CSC) marker. Clinical data show that a high frequency of ITGA7(+) cells in OSCC tissues is significantly associated with poor differentiation, lymph node metastasis and worse prognosis...

OBJECTIVES: Although abdominal visceral fat has been associated with erosive oesophagitis in cross-sectional studies, there are no data that describe its longitudinal effects. We aimed to evaluate the longitudinal effects of abdominal visceral fat on the development of new erosive oesophagitis in patients who did not have erosive oesophagitis at baseline. MATERIALS AND METHODS: This was a single-centre prospective study. A total of 1503 participants without erosive oesophagitis at baseline were followed up for 34 months and they underwent oesophagogastroduodenoscopy and computed tomography at both baseline and during follow-up...

Eosinophilic esophagitis (EoE) is an antigen-driven T cell-mediated chronic inflammatory disease where food and environmental antigens are thought to have a role. Human eosinophils express the immunoregulatory protein galectin-10 and have T cell suppressive capacity similar to regulatory T cells (Tregs ). We hypothesized that one function of eosinophils in EoE might be to regulate the T cell-driven inflammation in the oesophagus. This was tested by evaluating the suppressive capacity of eosinophils isolated from the blood of adult EoE patients in a mixed lymphocyte reaction...

Complete pharyngo-oesophageal stricture (PES) after radiotherapy for head and neck cancer is a relatively rare and difficult complication to manage. Historically this condition has been treated surgically, but endoscopic approaches are now available. We present a 61-year-old man with an epidermoid carcinoma of the supraglottic stage and a micro-invasive epidermoid carcinoma of the oropharynx treated surgically and subsequently by adjuvant radiotherapy. Eight months after the end of the radiotherapy, a complete PES was diagnosed and treated with a combined anterograde-retrograde endoscopic dilation (CARD)...

The host inflammatory response plays an important role in many solid malignancies. Studies on oesophageal adenocarcinomas (EACs) point towards a beneficial role of pronounced immunoreaction, however, congruent results have yet to be obtained. We analysed 111 primary resected EAC using a tissue microarray containing three cores of the tumour centre and the periphery per case. Overall inflammation was assessed by histomorphology. Tumour infiltrating lymphocytes (TILs) were characterised by immunohistochemistry for CD3, CD8 and FoxP3, and evaluated by image analysis (Aperio ImageScope)...

A substantial increase in the incidence of oesophageal adenocarcinoma has been observed in Western countries during the past 30 years, which may be related to the parallel rise of the obesity prevalence. On the other hand, incidence rates of oesophageal squamous cell carcinomas, the other major histological type of oesophageal cancer, have remained relatively stable. Epidemiological research of the past decades has identified obesity as risk factor for oesophageal adenocarcinoma. Studies investigating general obesity as assessed by body mass index (BMI) provide evidence for a strong positive association with oesophageal adenocarcinoma...

Epiphrenic oesophageal diverticula are rare and often asymptomatic. In this case report a 58-year-old woman was diagnosed with an epiphrenic oesophageal diverticulum, which developed an oesophagobronchial fistula leading to a pulmonary abscess in the right lower lobe, septicaemia and acute respiratory failure. The patient underwent right lower lobectomy and the diverticulum was stapled off the oesophagus. The post-operative course was uneventful. This complication is only rarely described previously.

AIMS: Complications from catheter ablation for atrial fibrillation (AF) are well described. Changing aspects of AF ablation including patient populations referred, institutional experience, and emerging catheter and pharmacological options may impact complication rates. We assessed procedural complication trends in AF ablation patients from 2003-2015 to identify what factors affect adverse event rates. METHODS AND RESULTS: We evaluated consecutively enrolled patients undergoing initial AF ablation from 2003 through 2015...

BACKGROUND: Barrett's oesophagus (BO) is a premalignant condition associated with the development of oesophageal adenocarcinoma (OAC). Despite the low risk of progression per annum, OAC is associated with significant morbidity and mortality, with an estimated 5-year survival of 10%. Furthermore, the incidence of OAC continues to rise globally. Therefore, it is imperative to detect the premalignant phase of BO and follow up such patients accordingly. SUMMARY: The mainstay diagnosis of BO is endoscopy and biopsy sampling...

BACKGROUND: Barrett's oesophagus (BO) is a premalignant condition associated with the development of oesophageal adenocarcinoma (OAC). Globally, the incidence of OAC is rising. Furthermore, the prognosis regarding the morbidity and mortality of OAC is bleak, with an estimated 5-year survival of 10-15%. Hence, detection of the premalignant phase is paramount. Endoscopy and biopsy sampling is the mainstay of diagnosis. Patients may present with symptoms of gastro-oesophageal reflux disease (GORD) or be completely asymptomatic...

More than 800 oesophageal tumours are diagnosed each year in Hungary. The disease is characterized by high mortality. The curative treatment traditionally surgical, although the study results of recent decades pointed out that patient outcome can be improved with the proper application of radio- and chemotherapy. The diverse study designs, the low number of recruited patients and the sometimes conflicting results make the determination of optimal treatment difficult. The aim of this work is to facilitate the choice of treatment modality with the best outcome, especially with the view of medical oncologists...
