Laparoscopic appendectomy is progressively accepted as the treatment of choice for acute appendicitis. Although the surgical technique of laparoscopic appendectomy has been well established, some controversy exists regarding the closure of the appendiceal stump. The available methods for stump closure are currently: pre-knotted loops (Roeder Loops or Endoloop, linear stapler and polymeric clips. A new device is a the DS Titanium Ligation Clip. The design of the DS-Clip is characterized by two parallel shanks.

The aim of this study is to collect data of a large number of patients treated with the product in real-life clinical routine.
