Abstract:
Objective: To invent the cost efficient home made bovine pericardium buttressing the staple lines in lung volume reduction surgery, and evaluate its feasibility by the means of animal test. Methods: the bovine pericardium of certain type of cattle was chosen, and special management was applied on it, making a sheath like product especially for LVRS. A serial types named A 1, A 2 and A 3 were prepared for the dog model pre clinical experimental test. The smoothness of stapling and dividing, the effectiveness of sealing, and the endurance of pressure were recorded as the index of judgment. Results: Products of all these three types were satisfactory in different degree for utilization, while the type of A 3 was found to suit best. Conclusion: In this study, the home made bovine pericardium buttressing the staple line in LVRS showed satisfactory characteristic in the animal test, and it should have great potential value in the coming clinical use.
