We aimed to assess the effect of donor pancreas extraction time (ET) on postoperative complications and graft function after pancreas transplantation (PT). We analyzed all consecutive donor pancreas procurements for the simultaneous pancreas and kidney transplantation (SPK) and the associated PT in a Swiss transplant center over a 20-year period. Pancreas ET was defined as the time from cold flush to static storage of the pancreas on ice. The primary endpoint was the effect of extraction time on surgical complications. Secondary endpoints comprised the effect of ET on graft function (insulin-free survival) and graft pancreatitis. Of 115 procured pancreas grafts the median donor pancreas ET was 65 min (IQR: 48-78 min). In multivariable analysis, ET did not negatively affect major complications (OR 1.41 [95% CI: .59-3.36]; p = .438) and insulin-free survival (HR 1.42 [95% CI: .55-3.63]; p = .459). The median CIT was 522 (441-608) min. CIT was associated with major complications (OR 2.51 [95% CI: 1.11-5.68]; p = .027), but without impact on insulin-free survival (HR 1.94 [95% CI: .84-4.48]; p = .119). Patients with and without graft pancreatitis had no statistically significant differences in ET and CIT (p = .164 and p = .47, respectively). In multivariable analysis, Amylase levels > 270 U/L on postoperative day 1 were significantly associated with major complications (OR 3.61 [95% CI: 1.06-12.32]; p = .040). Our results suggest that although no effect of ET on complications and graft function after PT was found, shorter CIT and less graft pancreatitis can have a positive impact on surgical complications. Results could possibly be influenced by the exceptional quality of the pancreas donors, with short travel distances and preservation times in Switzerland.
我们旨在评估供体胰腺摘取时间(ET)对胰腺移植(PT)术后并发症及移植物功能的影响。我们分析了瑞士某移植中心在20年期间所有连续进行的胰肾联合移植(SPK)的供体胰腺获取情况以及相关的PT。胰腺ET定义为从冷灌注到胰腺在冰上静态保存的时间。主要终点是摘取时间对手术并发症的影响。次要终点包括ET对移植物功能(无胰岛素生存)和移植物胰腺炎的影响。在115个获取的胰腺移植物中,供体胰腺ET的中位数为65分钟(四分位间距:48 - 78分钟)。在多变量分析中,ET对主要并发症无负面影响(比值比1.41 [95%置信区间:0.59 - 3.36];p = 0.438),对无胰岛素生存也无影响(风险比1.42 [95%置信区间:0.55 - 3.63];p = 0.459)。冷缺血时间(CIT)的中位数为522(441 - 608)分钟。CIT与主要并发症相关(比值比2.51 [95%置信区间:1.11 - 5.68];p = 0.027),但对无胰岛素生存无影响(风险比1.94 [95%置信区间:0.84 - 4.48];p = 0.119)。有和没有移植物胰腺炎的患者在ET和CIT方面无统计学显著差异(分别为p = 0.164和p = 0.47)。在多变量分析中,术后第1天淀粉酶水平>270 U/L与主要并发症显著相关(比值比3.61 [95%置信区间:1.06 - 12.32];p = 0.040)。我们的结果表明,虽然未发现ET对PT术后并发症及移植物功能有影响,但较短的CIT和较少的移植物胰腺炎可能对手术并发症有积极影响。结果可能受到瑞士胰腺供体质量优异、运输距离短及保存时间短的影响。
