[Disease-adapted closure of the appendicular stump in laparoscopic appendectomy]

The frequency of laparoscopic appendectomy has dramatically increased with it now being the standard procedure for acute appendicitis in many hospitals in Germany. Hence, these hospitals require the personnel, the technique as well as the expertise to guarantee a top standard and quality of appendectomies at all times. Only this will meet the requirements of the high case load and the socio-economical importance of appendectomies. The closure of the appendicular stump is a critical step of this procedure. The three most commonly used techniques consist of the endo-loop, the clip and the endo-stapler. The endo-stapler has the advantage of offering closure and transection of the appendix in one step; it can be employed in all cases of appendicular inflammation; and it allows a partial caecal resection. However, it is quite expensive. The clip and the endo-loop offer the same cost-effectiveness, yet the clip appears to be simpler in use compared to the loop. Also, sharing this feature with the stapler, it offers the possibility of closing and transecting the appendix before dissecting the mesoappendix. A disadvantage of the clip not being shared with the loop is the limitation of clips to appendicular diameters of only up to 16 mm. In summary, we propose a cost-effective disease-adapted closure of the appendicular stump employing the clip in standard appendectomies, with the endo-loop being a good alternative. If clip or loop cannot be applied the stapler is the technique of choice. In particular, it should be used if the base of the appendix is inflamed. Adopting this pathway helps to control the still somewhat higher costs of laparoscopic appendectomies compared to classical open appendectomies.
