Adult-to-adult living donor liver transplantation (AA-LDLT) has better outcomes when a graft weight to recipient weight ratio (GW/RW) > 0.8 is selected. A smaller GW/RW may result in small-for-size syndrome (SFSS). Portal inflow modulation seems to effectively prevent SFSS. Donor right hepatectomy is associated with greater morbidity and mortality than left hepatectomy. In an attempt to shift the risk away from the donor, we postulated that left lobe grafts with a GW/RW < 0.8 could be safely used with the construction of a hemiportocaval shunt (HPCS). We combined data from 2 centers and selected suitable left lobe living donor/recipient pairs. Since January 2005, 21 patients underwent AA-LDLT with left lobe grafts. Sixteen patients underwent the creation of an HPCS between the right portal vein and the inferior vena cava. The portocaval gradient (portal pressure À central venous pressure) was measured before the unclamping of the shunt and 10 minutes after unclamping. The median actual graft weight was 413 g (range ¼ 350-670 g), and the median GW/RW was 0.67 (range ¼ 0.5-1.0). The portocaval gradient was reduced from a median of 18 to 5 mmHg. Patient survival and graft survival at 1 year were 87% and 81%, respectively. SFSS developed in 1 patient, who required retransplantation. Two patients died at 3 and 10 months from a bile leak and fungal sepsis, respectively. The median recipient bilirubin level and INR were 1.7 mg/dL and 1.1, respectively, at 4 weeks post-transplant. One donor had a bile leak (cut surface). This is the first US series of small left lobe AA-LDLT demonstrating that the transplantation of small grafts with modulation of the portal inflow by the creation of an HPCS may prevent the development of SFSS while at the same time providing adequate liver volume. As it matures, this technique has the potential for widespread application and could positively effect donor safety, the donor pool, and waiting list times. Liver Transpl 16:649-657,

Surgical lengthening with both Bianchi and STEP procedures results in improvement in enteral nutrition, reverses complications of TPN and avoids intestinal transplantation in the majority with few surgical complications. Intestinal transplantation can salvage most patients who later develop life-threatening complications or fail to wean TPN.

With an aggressive medical/surgical approach, even patients with intestinal failure and advanced liver disease can avoid transplantation. Patients in the IRP showed improved liver function and nutritional parameters with the ability to discontinue PN while maintaining growth. Early referral of these patients to specialized centers before the development of advanced liver disease is recommended.

Adenovirus infections affected 24% of recipients and developed mostly during the first 6 months after transplantation. Small bowel is the most frequently involved site. Younger age at transplantation is a risk factor for adenovirus infection; whereas cytomegalovirus D+/R- sero-status seems to be protective.
