PHILADELPHIA — without raising the risk for rebleeding, if the initial ligation successfully controls bleeding.
“This approach would allow earlier discharge from the hospital and reduce the risk of adverse events, all without sacrificing treatment efficacy or compromising patient safety,” Sushrut Ingawale, MD, MBBS, Quinnipiac University School of Medicine, North Haven, and St. Vincent’s Medical Center, Bridgeport, both in Connecticut, said in a presentation at the annual meeting of the American College of Gastroenterology (ACG).
Ingawale called for a “re-evaluation of existing protocols, emphasizing the potential to update current protocols to reflect shorter, more personalized” duration of vasoconstrictor therapy in these patients.

Commenting on this research, Nancy Reau, MD, AGAF, of Rush University in Chicago, Illinois, said: “We should always question the standard of care.”
“Vasoconstrictors for 5 days is the standard of care, but this could lead to prolonged hospitalization in patients who are otherwise doing well after endoscopic intervention. Recognizing that a shorter course of vasoconstrictor treatment may have equal outcome is very important though it may not be appropriate for all patients, especially those at high risk for rebleeding,” said Reau.
Outdated Guidelines?
In his presentation, Ingawale noted that current guidelines that recommend continuing vasoconstrictors, like octreotide or terlipressin, for at least 3-5 days after EVL for acute variceal bleeding are based primarily on old studies in which sclerotherapy was the primary hemostatic method.
The study team assessed comparative outcomes based on the duration of vasoconstrictors after EVL for acute variceal bleeding in a systematic review and network meta-analysis of 11 randomized controlled trials.
The studies had a total of 816 patients who were grouped based on the duration vasoconstrictor therapy: 24 hours or less (group 1), 24-72 hours (group 2), and 72-120 hours (group 3).
There was no significant difference in the risk for rebleeding in group 1 (risk ratio [RR], 1.36; 95% CI, 0.48-3.52) and group 2 (RR, 1.34; 95% CI, 0.42-4.54) vs group 3.
“This finding was even consistent when we compared individual durations” of 0, 12, 24, 48, and 72 hours vs 120 hours, Ingawale said.
There was also no statistically significant difference in the 5-day mortality risk between group 1 (RR, 0.66; 95% CI, 0.09-2.52) and group 2 (RR, 1.08; 95% CI, 0.15-6.43) or the 30-day mortality risk between group 1 (RR, 1.18; 95% CI, 0.51-2.51) and group 2 (RR, 0.98; 95% CI, 0.36-2.52) vs group 3.
Rapidly Evolving Area
“Our network meta-analysis did not show any benefit of continuing vasoconstrictors after EVL,” the researchers wrote in their conference abstract. Despite historical precedent, shorter durations may be adequate, “potentially enabling earlier hospital discharge without compromising patient outcomes.”
Ingawale suggested future research should look to identify the subset of patients at a risk for failure to control bleeding who might benefit from the continuation of vasoconstrictors.
“Management of complications of portal hypertension are rapidly evolving and this study will add to the data that drives our guidelines. Seeing this data in a peer reviewed publication will add the necessary validity to impact a change in the treatment paradigm,” Reau said.
The study had no specific funding. Ingawale had no relevant financial relationships. Reau disclosed various relationships with AbbVie, Gilead, Arbutus, Intercept, and Salix.
