The impact of feeding after endoscopic treatment of gastroesophageal varices has never been investigated. It is still unknown whether early feeding may increase early rebleeding in patients with acute esophageal variceal bleeding treated with EVL. It is customary for clinicians to institute fasting for 2 or 3 days after emergency EVL. This may be a safe approach to watch against early rebleeding. However, many patients would be fasting for a longer time and nutrition may be impaired, possibly resulting in aggravation of ascites. Thus, the investigators conduct a controlled study to evaluate whether early feeding have a bad impact on patients receiving emergency EVL or histoacryl injection for bleeding gastric varices.

The purpose of this study is to determine if the use of specialized compression garments, in comparison to standard compression, improves early patient outcomes after endovenous ablation.

The study aims to evaluate the feasibility of transnasal endoscopy in patients with portal hypertension, cirrhotic and non-cirrhotic. The incidence of the procedure's adverse effects, the patient's tolerance and his/her opinion about the exam are analyzed. In addition, the interobserver matched for the discoveries found in the study is carried out.

Compression stockings are traditionally worn for a period of time after varicose vein surgery to reduce pain and bruising. The investigators provide an ambulatory endovenous ablation service. Patients come to the Veins Unit, receive oral sedation, have their veins treated with either laser or radiofrequency ablation plus phlebectomies* under local anaesthetic, recover for an hour and then go home. *Phlebectomy describes the technique of pulling out small varicose veins through small incisions in the overlying skin. The standard practice of the Veins Unit is to advise patients to wear class two compression stockings for four weeks post-operatively. Many patients would prefer a shorter period of time in stockings. The Nice Guidelines for Varicose Veins has posed the question: 'How long should stockings be worn for after endovenous ablation?' Three trials have addressed this issue: Bakker looked at patients who wore stockings for either two or seven days after laser ablation only; the group who wore stockings for seven days fared better. Elderman looked at patients who either wore no stockings or stockings for two weeks after laser ablation only; the group who wore stockings for two weeks had less pain. Krasznai looked at patients who wore stockings for either 4 hours or 72 hours after radiofrequency ablation only; there was no significant difference in post-op pain among groups. None of these trials included patients who had phlebectomies at the same time. This study aims to answer the question 'How long is it necessary to wear compression stockings for after endovenous ablation (either laser or radiofrequency) plus concomitant phlebectomies?' The investigators plan to divide 110 patients into two groups- either 'stockings for 2 weeks' (trial group) or 'stockings for 4 weeks' (usual treatment group). Pre-operatively, all patients will fill out a pain score and two short quality of life questionnaires, one specific to varicose veins. Post-operatively at home, all patients will be asked to keep a diary of pain and analgesia use. They will also document bruising at seven days on charts and on a visual scale. At their four week clinic review, all patients will be asked to fill out a pain and bruising score, a bruising chart and the two short quality of life questionnaires again. The group with the best pain, bruising and quality of life scores post-operatively will help guide duration of compression therapy for future patients.

Chronic venous insufficiency occurs when your leg veins don't allow blood to flow back up to your heart. Normally, the valves in your veins make sure that blood flows toward your heart. But when these valves don't work well, blood can also flow backwards. This can cause blood to collect (pool) in the legs. Chronic venous disease is a highly prevalent condition in the general population, and it has a significant impact on quality of life. While it is usually manifested by obvious signs, such as varicose veins and venous ulcers, other symptoms of the disease are less specific. Among the other symptoms, which include heaviness, swelling, muscle cramps and restless legs, pain is the symptom that most frequently compels CVeD patients to seek medical aid. However, there is a substantial discrepancy between pain severity and clinically detectable signs of CVeD, questioned by several opposing studies. Further evaluation is needed to clarify this subject, and to analyse whether pain development predicts objective tool to evaluate pain by dosflexin exercise pre surgery and post and measure the severity of pain by heat stimulation .

Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. The aim of this study is to evaluate the efficacy of anticoagulation in patients with JAK2 mutation and gastroesophageal varices.

Acute esophageal variceal bleeding (AEVB) is a serious complication of cirrhosis, with high morbidity and mortality. The latest European recommendations(1) recommend the early implementation, within 72 hours following esophageal variceal bleeding, of a transhepatic porto-systemic shunt set up by transjugular route (TIPS) called "early TIPS" in patients at high risk of recurrence, i.e. Child C<14 or Child B with active bleeding at the time of endoscopy. The implementation of early TIPS appears to improve survival without transplantation in these patients, although the benefit among Child B patients without active bleeding has yet to be demonstrated. Renal failure is a determining factor in the prognosis of the cirrhotic patient. For patients with refractory ascites, or type 2 hepato-renal syndrome (i.e. chronic renal failure related to portal hypertension), the use of TIPS is recommended. Although a few studies with low levels of evidence have reported a benefit in the placement of TIPS in hepato-renal syndrome type 1 (i.e. acute renal failure related to portal hypertension), the European recommendations do not recommend the use of TIPS in this context due to lack of studies on the subject. Some studies have shown an improvement in renal function after performing TIPS in refractory ascites. To date, no studies have evaluated the impact of the implementation of early-TIPS on renal function in intensive care patients. The investigators would like to evaluate the impact on survival without liver transplantation on D28 of the implementation of early-TIPS in cirrhotic patients with AEVB requiring ICU hospitalization, compared to standard treatment (medical and endoscopic).
