NCT01283815

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.

Study Arms (2)

Conservative management

ACTIVE COMPARATOR

Patients are treated with intravenous Cefuroxime 1,5 g x 3 per day plus Metronidazole 500 mg x 3 per day. If the abscess is at least 3 cm in diameter percutaneous ultrasound guided drainage is performed.

Procedure: Conservative management with percutaneous drainage

Laparoscopic appendectomy

EXPERIMENTAL

Laparoscopic appendectomy and laparoscopic drainage of the abscess. If appendectomy is not possible due to technical difficulties only laparoscopic drainage is performed. Patients are treated with the same antimicrobial therapy as the control group

Procedure: Laparoscopic appendectomy

Interventions

Laparoscopic appendectomy and laparoscopic drainage of the abscess. If appendectomy is not possible due to technical difficulties only laparoscopic drainage is performed. Patients are treated with the same antimicrobial therapy as the control group (intravenous Cefuroxime 1,5 g x 3 per day plus Metronidazole 500 mg x 3 per day).

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Periappendicular abscess at least 2 cm in size

You may not qualify if:

  • Missing written informed consent
  • Antimicrobial therapy lasted over 24 hours before randomization
  • Attempt of drainage before randomization
  • Age over 80 years or under 18 years old
