TREATMENT OF ACUTE BLEEDING
HVPG >20 mmHg, Child-Pugh Class C, and active bleeding at endoscopy are the variables most consistently found to predict 5-day treatment failure
Child-Pugh class C, MELD score > 18, and failure to control bleeding or early rebleeding are the variables most consistently found to predict 6-week mortality

20th ANNIVERSARY
TREATMENT OF ACUTE BLEEDING In suspected variceal bleeding, vasoactive drugs should be started as soon as possible, before diagnostic endoscopy
Endoscopic therapy is recommended in any patient who presents with documented upper GI bleeding and in whom esophageal varices are the cause of bleeding
Patients with GI bleeding and features suggesting cirrhosis should have upper endoscopy as soon as possible after admission (within 12 hours)
Ligation is the recommended form of endoscopic therapy for acute esophageal variceal bleeding, although sclerotherapy may be used in the acute setting if ligation is technically difficult
Vasoactive drugs (terlipressin, somatostatin, octreotide, vapreotide) should be used in combination with endoscopic therapy and continued for up to 5 days
Endoscopic therapy with tissue adhesive (e.g. N-butyl-cyanoacrylate) is recommended for acute bleeding from isolated gastric varices (IGV) and those gastro-esophageal varices type 2 that extend beyond the cardia
EVL or tissue adhesive can be used in bleeding from gastroesophageal varices type 1 (GOV1)
Uncontrolled data suggest that self-expanding covered esophageal metal stent may be an option in refractory esophageal variceal bleeding, although further evaluation is needed
Persistent bleeding despite combined pharmacological and endoscopic therapy is best managed by TIPS with PTFE-covered stents
Rebleeding during the first 5 days may be managed by a second attempt at endoscopic therapy. If rebleeding is severe, PTFE-covered TIPS is likely the best option

TREATMENT OF ACUTE BLEEDING
An early TIPS within 72 hours (ideally < 24 hours) should be considered in patients at high-risk of treatment failure (e.g. Child-Pugh class C <14 points or Child class B with active bleeding) after initial pharmacological and endoscopic therapy
Balloon tamponade should only be used in massive bleeding as a temporary “bridge” until definitive treatment can be instituted (for a maximum of 24 h, preferably in an intensive care facility)

SECONDARY PROPHYLAXIS
Patients who fail endoscopic and pharmacological treatment for the prevention of rebleeding:
- Covered TIPS is effective and is the preferred option. Surgical shunt in
Child-Pugh A and B patients is an alternative if TIPS is unavailable.
- Transplantation provides good long-term outcomes in appropriate
candidates and should be considered. TIPS may be used as a bridge to
transplantation
Patients who have bled for IGV type I or GOV-2:
- N-butyl-cyanoacrylate or TIPS are recommended

AVH: MELD AND 5-DAY REBLEEDING
Hep 2005, Boyer and Haskal
…….. incidence of fatal complications (intra-abdominal hemorrhage, laceration of the hepatic artery or portal vein, and right heart failure) was 1.7% (range, 0.6%-4.3%). Interestingly, the risk of fatal complications was 3% in institutions that had performed fewer than 150 TIPS total compared with 1.4% in those that had performed a greater number. These data suggest that there is a learning curve associated with the safe creation of a TIPS. Major procedural complications are expected in no more than 3% of cases; if rates exceed these levels, internal quality assessment should be considered.
