Laparoscopic Management of Periappendicular Abscess

Phase 2

Completed

• Conditions: Appendicitis; Abdominal Abscess

• Registration Number: NCT01283815
• Lead Sponsor: Helsinki University Central Hospital

Brief Summary

According to retrospective studies the conservative management of periappendicular abscess is associated with decreased complication and re-operation rate compared with open appendectomy. Large abscesses require percutaneous drainage. Sometimes percutaneous drainage is not possible because of anatomical position of the abscess and surgical treatment is needed. The purpose of this study is evaluate whether laparoscopic appendectomy is suitable for the first-line treatment in patients with periappendicular abscess.

The hypothesis of the study is that laparoscopic management of periappendicular abscess is suitable for the first-line treatment and it does not increase time of hospitalization or complication rate compared with conservative management.
