Hematemesis in a Child With a Failed Kasai: Resuscitation, Endoscopy, and the Waitlist
A 6-year-old boy with biliary atresia treated with Kasai portoenterostomy at 48 days presents to a community emergency department with a 30-minute episode of hematemesis (about 250 mL of bright red blood) followed by melena. He is pale and lethargic. Heart rate 132, blood pressure 86/48, capillary refill 4 seconds, weight 18 kg. He has splenomegaly 6 cm below the costal margin and ascites on examination. Hemoglobin 7.0 g/dL, platelets 61,000/µL, INR 1.7, albumin 2.9 g/dL, bilirubin 3.1 mg/dL, creatinine 0.5 mg/dL. He has known grade II esophageal varices and takes propranolol. The nearest pediatric endoscopy suite is a 90-minute ambulance ride; the transplant center is 4 hours away. He has had no encephalopathy.
1. Write the immediate resuscitation and pharmacologic orders, and state what you would avoid.
Read the worked answer
Resuscitate restrictively and start splanchnic vasoconstriction before transport.
- Two large-bore IVs; 10–20 mL/kg crystalloid bolus, then packed red cells 10 mL/kg. Target hemoglobin 7–8 g/dL. Overtransfusion raises portal pressure and provokes rebleeding; do not chase a normal hemoglobin.
- Octreotide 1 µg/kg IV bolus (maximum 50 µg), then 1 µg/kg/h infusion, titrated to a maximum of about 5 µg/kg/h if bleeding continues. Continue for 24–48 hours after bleeding stops, then taper over 24 hours to avoid rebound.
- Ceftriaxone 50 mg/kg IV daily (maximum 2 g) for up to 7 days; bacterial infection precipitates variceal bleeding and death in cirrhotic children.
- Pantoprazole 1 mg/kg IV; vitamin K 0.3 mg/kg IV; check fibrinogen, glucose, and lactate; type and crossmatch.
- Airway assessment: intubate before transfer if there is massive ongoing hematemesis or any decline in consciousness. A nasogastric tube is safe and helps clear blood and confirm the source once the airway is protected.
Avoid:
- FFP solely to correct the INR; it raises portal pressure and volume without proven benefit in the absence of bleeding or a procedure.
- Platelet transfusion unless counts are very low with active bleeding.
- Delaying octreotide while arranging transfer. Call the accepting center and arrange pediatric endoscopy within 12–24 hours.
2. How do you choose among endoscopy, TIPS, and a surgical shunt in this child, and what is the timing?
Read the worked answer
Endoscopy first, TIPS as rescue or bridge, surgical shunt only if transplant is off the table.
- Endoscopy within 12–24 hours of stabilization for band ligation. Banding is feasible in most children over about 10 kg; sclerotherapy is an alternative in smaller children or when banding is not technically possible.
- If bleeding is uncontrolled at endoscopy, or rebleeding occurs despite two sessions, proceed to rescue TIPS. Pediatric TIPS requires an experienced interventional radiologist; consider portal vein anatomy (post-Kasai portal vein hypoplasia or thrombosis may make the procedure impossible), risk of encephalopathy, and the fact that a stent can complicate later transplant surgery.
- Balloon tamponade is a temporizing measure only, in an intubated child, for a maximum of 24 hours while awaiting definitive therapy.
- A distal splenorenal shunt or other surgical shunt is reserved for children who are not transplant candidates, because it distorts portal anatomy and complicates future transplantation.
Context that drives the decision:
- This child has ascites, thrombocytopenia, and an INR of 1.7: he has decompensated cirrhosis, and the bleed is a marker of severity. Concurrent transplant evaluation should begin now. TIPS here is best viewed as a bridge, not a destination.
3. Plan secondary prophylaxis and explain what this bleed means for listing and counseling.
Read the worked answer
Secondary prophylaxis:
- Repeat band ligation every 2–4 weeks until varices are eradicated, then surveillance endoscopy at 6–12 months.
- Continue a nonselective beta-blocker if tolerated: propranolol 1–2 mg/kg/day divided, titrated to about a 25% reduction in resting heart rate, with monitoring for hypotension and hypoglycemia.
- Avoid NSAIDs and aspirin; vaccinate for hepatitis A and B; treat ascites with sodium restriction and diuretics as tolerated.
Listing implications:
- A variceal bleed in a cirrhotic child does not automatically generate exception points. The calculated PELD may remain modest in a child with preserved bilirubin and albumin while the true mortality risk is high. This is a legitimate basis for a nonstandard MELD/PELD exception request: document the bleeding episode, endoscopic findings, failure of primary prophylaxis, ascites, and thrombocytopenia.
- At the same time, pursue living-donor evaluation; it may be faster and more reliable than an exception request.
Counseling:
- Explain that bleeding can recur, that transplant is the only definitive treatment for the portal hypertension, and that repeated bleeds, spontaneous bacterial peritonitis, or worsening synthetic function mean the wait must not be passive.
- Give the family a written emergency plan: which hospital, which number, and that octreotide should be started on arrival.
