Leaking from the appendical anastomosis, site where the appendix was removed is complication that is most likely a result of surgical technique used during appendectomy.
This leak may lead to peritonitis (inflammation of peritoneum, a membrane that lines the abdominal cavity) that can be generalized or in form of abscess.
Drainage of the abscesses with antibiotic irrigation and systemic antibiotic therapy are usual treatment.
Surgery is considered option in certain cases.
