目的 探讨应用带蒂大网膜治疗严重肝创伤的方法。方法回顾性地对1986~1999年收治的严重肝创伤应用带蒂大网膜填塞覆盖缝合术91例的临床资料进行分析。结果 治愈81例(89.0%)，死亡10例(11.0%)。术后近期出血、胆汁渗出4例(4.4%)，胆漏3例(3.3%)，膈下脓肿5例(5.5%)。结论 带蒂大网膜在救治严重肝创伤中有着重要的作用，对肝创面彻底清创、止血、妥善缝扎创口和胆管等是应用带蒂大网膜缝合术的先决条件。
OBJECTIVE: To validate the hemostatic properties of collagen sponge made in China. METHODS: The experimental model of superficial cut of liver was established in 20 Sprague-Dawley adult rats, which were divided into two groups randomly. Collagen sponge or gelatin sponge was used to cover the cut respectively. Hemostatic result was observed. Afterwards, standard liver trauma model by resection left front liver lobe was made, wound was treated with collagen sponge or gelatin sponge respectively. Hemostatic result was observed. Concurrent hemostatic time and bleeding amount were noted. At 7, 14 and 20 days after operation, intra-abdominal adhension, infection and healing state of liver were observed by exploratory laparotomy. The histological changes of regenerate liver tissue were observed by microscopy. RESULTS: Collagen sponge adhered to wound well. Concurrent hemostatic time and bleeding amount in collagen sponge group were superior to those of gelatin sponge (P lt; 0.05). The histological examination showed that collagen sponge was absorbed and degraded rapidly, regenerative hepatocytes could be induced. CONCLUSION: Collagen sponge has fine hemostatic properties and can induce regeneration of hepatocytes effectively. It is worth popularizing for its convenience in clinical application and its properties of rapid degradation and absorption.
