Purpose: Many disposable laparoscopic instruments are used in laparoscopic surgery. There are several disadvantages in use of disposable laparoscopic instruments, including cost ineffectiveness, environmental contamination, and resource recycling. In addition, a disposable specimen bag has been used in laparoscopic appendectomy. Use of the trans-trocar appendix removal technique provides several advantages compared to use of a specimen bag. Therefore, the aim of this study is to analyze the adequate trocar size for trans-trocar appendix removal. Methods: A total of 62 patients undergoing appendectomy between June 2012 and September 2012 were identified. After appendectomy, we performed a trans-trocar test using re-moved appendix specimen and trocars. Three different types of trocars were used for the trans-trocar test, 5 mm, 12 mm, and 11 mm Xcel? (Ethicon). We analyzed the success rate. Results: Significant relationships were observed between maximal specimen diameter and body mass index. When BMI was below 20, the success rate of the 11 mm trocar was 86% in the trans-trocar appendix removal test. When BMI was between 20 and 25, the success rate of the 12 mm trocar was 71%, but that of 11 mm was 57%. When BMI was above 25, the success rate of the 15 mm trocar was 62%. Conclusion: Although this study had many limitations, a large-sized trocar was needed for trans-trocar appendix removal in more body mass index. When BMI is below 20, an 11 mm trocar is recommended in trans-trocar appendix removal. When BMI is between 20 and 25, a 12 mm trocar is. When BMI is above 25, a 15 mm trocar and a disposable specimen bag are recommended. Further continuous study will be needed for analysis of clinical outcome.
