Intestinal transplantation (ITx) is a treatment for refractory intestinal failure (IF). However, the indications for and timing of ITx are still controversial because the course of IF is unknown. We performed a prospective multi-institutional cohort study to identify the prognostic factors for referral to an ITx facility. Patients under 18 years of age in Japan who suffered from IF and had received parenteral nutrition for longer than 6 months were enrolled in this study. They were followed up for 3 years. Seventy-two patients were followed. The mean age at the beginning of the study was 7.0 years. Diagnoses were short gut syndrome (n = 25), motility disorder (n = 45), and other (n = 2). The overall 3-year survival rate was 95%. The 3-year survival rate was 86% in patients with intestinal-failure-associated liver disease (IFALD) (n = 6) compared to 97% in those without IFALD (n = 66) (P = .0003). Furthermore, the 3-year survival rates of patients who did and did not meet the criteria for ITx were 82% (n = 11) and 97% (n = 62), respectively (P = .034). Six (44%) of 14 patients whose performance status (PS) was ≥3 at enrollment were dead or still had a PS ≥ 3 at 3 years. This study indicates that IFALD is a poor prognostic factor in pediatric patients with IF. Our indication for ITx, namely the presence of IFALD or loss of more than 2 parenteral nutrition access sites, seems to be applicable.
肠道移植(ITx)是治疗难治性肠衰竭(IF)的一种方法。然而,由于IF的病程尚不清楚,ITx的适应证和时机仍存在争议。我们进行了一项前瞻性多机构队列研究,以确定转诊至ITx机构的预后因素。日本18岁以下患有IF且接受肠外营养超过6个月的患者被纳入本研究。对他们进行了3年的随访。共随访了72例患者。研究开始时的平均年龄为7.0岁。诊断包括短肠综合征(n = 25)、动力障碍(n = 45)和其他(n = 2)。总体3年生存率为95%。与无肠衰竭相关肝病(IFALD)的患者(n = 66)的97%相比,患有IFALD的患者(n = 6)的3年生存率为86%(P = .0003)。此外,符合和不符合ITx标准的患者的3年生存率分别为82%(n = 11)和97%(n = 62)(P = .034)。14例入组时体能状态(PS)≥3的患者中有6例(44%)在3年时死亡或PS仍≥3。本研究表明,IFALD是小儿IF患者的不良预后因素。我们的ITx适应证,即存在IFALD或失去超过2个肠外营养通路部位,似乎是适用的。
