Expanded polytetrafluoroethylene (ePTFE) was used to repair 11 large abdominal wall defects in ten patients. Three patches were fixed to the adjacent abdominal aponeurosis with a single row of sutures; seven patches were implanted with a 1-2 cm overlap of patch and aponeurosis and a double row of sutures. Recurrent buttonhole hernias were found in two patients, in both of whom a single row of sutures had been used. This reherniation was due to insufficient anchorage of the patch to the fascia. It is concluded that ePTFE is a useful material to repair large abdominal wall defects provided the patch is fixed to the aponeurosis with an overlap and a double row of sutures to prevent buttonhole hernias.
采用膨体聚四氟乙烯（ePTFE）修复10例患者的11处大型腹壁缺损。3块补片用单排缝线固定于相邻的腹腱膜；7块补片植入时补片与腹腱膜重叠1-2厘米并采用双排缝线。2例患者出现复发性扣眼疝，这2例均使用了单排缝线。这种复发疝是由于补片与筋膜的固定不充分所致。得出的结论是，只要补片与腹腱膜重叠并用双排缝线固定以防止扣眼疝，ePTFE就是修复大型腹壁缺损的一种有用材料。
