*Purpose: We describe trends in intestinal transplantation use and outcomes over time in the USA.
*Methods: We use the cohort of intestinal and multivisceral transplants 1990-2019 in the UNOS/SRTR datasets. Eras were defined as 1990-1999, 2000-2009, 2010-2019. Summary statistics were calculated by era. Patient and death-censored graft survival were assessed by era, stratified by pediatric (<18 years at transplant) and adult recipients.
*Results: A total of 3035 transplants were performed, 398 in the first era, 1485 in the second, 1152 in the third. The proportion of adult recipients increased over time (35%, 44%, 59% respectively). The number of infant (<5 years) recipients decreased in the last decade (45%, 44%, 26%). More transplants were performed in recipients with a previous intestinal transplant over time (8%, 9.6%, 12.2%). Fewer livers were included in multivisceral grafts (60% , 56%, 48%). The number of grafts including the duodenum, large intestine, or stomach increased over time. The most common indication for intestine-only and multivisceral transplants in adults remained short gut syndrome (66% in era 3). In children, intestine-only grafts were most commonly used for functional bowel problems (22% in era 3), and multivisceral grafts for gastroschisis (23% in era 3). 1- and 5-year survival improved over time in children (First era: 65%, 46%; second era 75%, 60%; third era 85%, 72% respectively. KM log rank era 2 vs. 3 p<0.0005), while adult survival plateaued (First era: 65%, 37%; second era 79%, 54%; third era 77%, 51%, respectively. KM log rank era 2 vs. 3 p=0.15). A similar trend was observed in death-censored graft survival (Figure 1).
*Conclusions: A greater proportion of intestinal transplants are now being done in adults, perhaps as a result of improving intestinal rehabilitation in pediatric patients. Graft and patient survival has plateaued for the past decade, highlighting the ongoing need for improving long-term outcomes in adult recipients. As technique and outcomes improve, re-transplantation has become a feasible option in those patients who need it.
