Outcomes of intestinal transplants (ITx; n = 977) for pediatric patients are examined using the United Network for Organ Sharing data from 1987 to 2009. Recipients were divided into four age groups: (1) <2 years of age (n = 569), (2) 2-6 years (n = 219), (3) 6-12 years (n = 121) and (4) 12-18 years (n = 68). Of 977 ITx, 287 (29.4%) were isolated ITx and 690 (70.6%) were liver and ITx (L-ITx). Patient survival for isolated ITx at 1, 3 and 5 years, 85.3%, 71.3% and 65.0%, respectively, was significantly better than L-ITx, 68.4%, 57.0% and 51.4%, respectively, (p = 0.0001); this was true for all age groups, except for patients <2 years of age. The difference in graft survival between isolated ITx and L-ITx was significant at 1 and 3 years (Wilcoxon test, p = 0.0012). After attrition analysis of graft survival of patients who survived past first year, 3 and 5 years, graft survival for L-ITx patient was significantly better than those for isolated ITx. Isolated ITx should be considered early before the onset of liver disease in children >2 with intestinal failure but is not advantageous in patients <2 years.
本研究使用 1987 年至 2009 年美国器官共享网络(UNOS)的数据,对儿童肠移植(ITx)患者的结局进行了分析。将受者分为 4 个年龄组:(1)<2 岁(n = 569);(2)2-6 岁(n = 219);(3)6-12 岁(n = 121);(4)12-18 岁(n = 68)。977 例 ITx 中,287 例为单纯 ITx(29.4%),690 例为肝肠联合移植(L-ITx)(70.6%)。单纯 ITx 的患者 1、3 和 5 年生存率分别为 85.3%、71.3%和 65.0%,显著高于 L-ITx 的 68.4%、57.0%和 51.4%(p = 0.0001),除<2 岁患者外,这在所有年龄组中均为如此。1 年和 3 年时,单纯 ITx 和 L-ITx 的移植物存活率差异具有统计学意义(Wilcoxon 检验,p = 0.0012)。在对存活超过第 1 年的患者进行移植物存活的淘汰分析后,L-ITx 患者的 3 年和 5 年移植物存活率显著优于单纯 ITx 患者。对于有肠衰竭但无肝病的>2 岁儿童,应尽早考虑单纯 ITx,但对于<2 岁的患者则无优势。
