Forty rats were laparotomized and subjected to a standardized cecal trauma. In half the number of the rats, the injured cecum was embedded in oxidized regenerated cellulose (Surgicel). In the remaining 20 rats, which served as controls, the cecum was left uncovered. The rats were sacrificed at 14 days after the operation and examined for intraperitoneal adhesions. Adhesions were significantly (p less than 0.001) less common in the group treated with oxidized regenerated cellulose. In a separate series eight rats were used for histological examination of the traumatized cecal wall. No macroscopic residuum of the implant was seen after one or two weeks. However, the histological examination demonstrated small remnants surrounded by ingrowing fibroblasts and inflammatory cells.
40只大鼠接受剖腹手术,并遭受标准化的盲肠创伤。在一半数量的大鼠中,将受伤的盲肠植入氧化再生纤维素(Surgicel)中。其余20只大鼠作为对照,盲肠未作处理。术后14天处死大鼠,检查腹腔粘连情况。氧化再生纤维素治疗组的粘连明显较少(p<0.001)。在另一个系列实验中,8只大鼠用于对创伤盲肠壁进行组织学检查。一两周后未观察到植入物的宏观残留物。然而,组织学检查显示有小的残留物,周围有向内生长的成纤维细胞和炎症细胞。
