Acute variceal bleeding (AVB) is recognized as a leading cause of mortality in patients with cirrhosis.
[1]
Importantly, an episode of AVB comprises not only the risk of bleeding and re-bleeding but also the risk of triggering other complications, among which acute-on-chronic liver failure (ACLF) stands out.2

The term ACLF defines an abrupt worsening of hepatic and extrahepatic organ failure in patients with underlying liver disease. On the other side, transjugular intrahepatic portosystemic shunt (TIPS) is a highly effective tool to treat patients with portal hypertension and variceal bleeding, thus markedly reducing the risk of rebleeding, further liver decompensation and death. One of the main concerns regarding TIPS is its potential deleterious impact on patients with a markedly deteriorated liver function and ACLF, given that TIPS insertion could reduce hepatic perfusion and worsen liver function.In this setting, we read with great interest the study by Kumar et al. “Determinants of mortality in patients with cirrhosis and uncontrolled variceal bleeding”
[6]
that addresses the important issue of whether the insertion of a rescue TIPS in patients with failure to control AVB (with or without ACLF) improves survival. Kumar et al. evaluated data from 174 consecutive patients with failure to control AVB admitted to their intensive care unit; however, only 78 patients received TIPS and 104 were managed differently. The study published herein evaluated survival according to the presence or not of ACLF at the moment of TIPS placement, demonstrating that TIPS improved survival in patients with failure to control AVB and ACLF but not in those without ACLF.Despite the great implications of this study, its results should be interpreted carefully before extrapolating them to general practice. The study sends a confusing message as it seems to challenge the need for TIPS in patients with refractory bleeding. It is striking that, according to the authors’ results, TIPS insertion does not affect survival in patients without ACLF, thus calling into question the need to provide a definitive treatment with TIPS in patients with failure to control AVB. Most probably, the problem lies in the definition of “failure to control bleeding”. Refractory bleeding is usually defined as a variceal bleeding that does not respond to the combination of vasoactive drugs and endoscopic treatment. Nevertheless, the authors have expanded the notion to patients that still had endoscopic options, thus confusing the reader when stating that patients that did not undergo TIPS had a similar survival than those that did. Also, the authors do not detail the treatment applied in patients that did not undergo TIPS, which would undeniably have influenced survival. How was failure to control bleeding controlled without using TIPS?
On another note, this study sets the perfect scenario to stablish the cut-off point and futility criteria for TIPS placement in patients with failure to control AVB. Although the authors show that the presence of grade 2-3 ACLF prior to the acute episode of variceal bleeding is an independent prognostic factor of mortality, unfortunately, they do not show whether there is a subgroup of patients with new-onset ACLF in whom TIPS may be futile. Also, it would have been interesting to see whether the different events triggering ACLF (infection, alcoholic hepatitis), or the presence of ACLF prior to bleeding, influence outcomes.
Finally, it is worth mentioning that the authors do not detail the proportion of patients that would have fulfilled criteria for preemptive TIPS (pTIPS) before exhibiting failure to control AVB. Admittedly, and in spite of the overwhelming amount of data supporting the use of pTIPS, it is a fact that in the real-life setting the implementation of pTIPS is not as high as it should be.

Accordingly, the present study also shows the lack of implementation of pTIPS, which could justify the large number of patients reaching the point of requiring a rescue TIPS. Nevertheless, it would have been interesting to present these data (proportion of patients that would have fulfilled criteria for pTIPS) as a means of reinforcing the concept that, at least to some extent, the setting evaluated by the present study could have been avoided.Financial support
