Management of Variceal Bleed in Waitlisted Patients
摘要
Management of variceal bleeding in patients on a liver transplantation (LT) waitlist is highly challenging. Treatment approach varies depending on the listing for the type of LT protocol (living donor liver transplant [LDLT]/diseased donor liver transplant [DDLT]). The initial steps of treatment in both protocols are the same. After an episode of controlled index bleed, LDLT candidates should be considered for an early transplant. Delay in transplant due to any reason necessitates initiation of standard treatment in these patients, since recurrent bleeding may lead to further decompensation and other life-threatening complications. DDLT candidates also need to be prioritized in the waitlist, though the timing of transplant still depends on the availability of deceased donors. Hence, these patients should be treated with the standard treatment of care for variceal bleeding. Those with refractory variceal bleed should undergo immediate LT; if immediate LT not possible, rescue therapies like balloon tamponade, self-expanding metal stents (SEMS), or transjugular intrahepatic portosystemic shunt (TIPS) can be used to achieve hemostasis and as a bridge to LT. Preemptive TIPS should be considered early in high-risk patients for recurrent or refractory bleed. For refractory gastric variceal bleed, balloon-occluded retrograde transvenous obliteration (BRTO) and endoscopic ultrasound (EUS)-guided coiling are highly effective in controlling bleeding till liver transplant can be carried out. Appropriate prevention, early recognition, and timely intervention for variceal bleeding in the patient awaiting LT are the keys to a positive outcome in the peri-transplantation period.
