目的低出生体重儿小肠直径小，近、远端肠管直径差大，肠吻合术难度大，但目前还没有最佳尺寸的训练模型。因此，我们开发了一种新的肠吻合训练模型，模仿肠道的大小在低出生体重儿，并评估其面临和结构validity.MethodsTwo肠道模型开发与crossMedical，Inc。使用亲水性丙烯酸材料（湿模型）或聚氨酯软树脂（干模型）。模拟肠道的内径在口端为15 mm，在肛端为6 mm。13名小儿外科医生进行吻合术，并回答了questionnaire.ResultsIn问卷调查，湿模型有显着高于干模型在“外观”，“柔软度”和“有用的培训”的分数。在湿模型吻合结果中，吻合口漏压与低出生体重儿肠吻合经验数显著相关（相关系数= 0.64，P = 0.035）。其泄漏压力与临床经验显着相关;因此，证明了结构有效性。
PurposeIt is difficult to perform intestinal anastomosis in low-birth-weight infants because the intestinal diameter is small and the discrepancy in diameter of the proximal and distal intestines is often large, but there has been no optimal-sized training model. Therefore, we developed a new intestinal anastomosis training model that imitated the size of the intestine in low-birth-weight infants, and evaluated its face and construct validity.MethodsTwo intestinal models were developed with crossMedical, Inc. using a hydrophilic acrylic material (wet model) or a polyurethane soft resin (dry model). The inner diameter of the simulated intestinal tract was 15 mm on the oral end and 6 mm on the anal end. Thirteen pediatric surgeons performed anastomosis and responded to the questionnaire.ResultsIn the questionnaire, the wet model had significantly higher scores than the dry model in “appearance”, “softness” and “usefulness for training”. In the anastomotic results of the wet model, the anastomosis leak pressure was significantly correlated with the number of intestinal anastomotic experiences in low-birth-weight infants (correlation coefficient = 0.64,P= 0.035).ConclusionsThe wet-type intestinal anastomosis model showed good face validity. Its leak pressure had a significant correlation with clinical experience; thus, construct validity was demonstrated.
