Incisional hernia appendicitis: A report of two unique cases and literature review.

Background: Acute appendicitis is a common surgical emergency. The presence of an inflamed appendix in an incisional hernia is rare. Incisional hernias complicate both open and laparoscopic surgery.

Methods: We describe two unique cases of acute appendicitis within incisional hernias following an open cholecystectomy and a diagnostic laparoscopy. Acute appendicitis was diagnosed intraoperatively and a formal appendicectomy was performed with subsequent primary repair of the hernial defect in each case.

Conclusions: The method chosen for primary repair of an incisional hernia containing an acutely inflamed appendix depends on a number of factors including size of hernial defect and degree of contamination. Closure of 5mm port sites is not routine in current surgical practice. Herniation of intra-abdominal contents through such defects can occur rarely. The repair of an incisional hernia using mesh in a contaminated surgical field is controversial. There may be advantages in the use of biological meshes. Conclusions: Surgical awareness of potential complications relating to the management of incisional hernia appendicitis is of primary importance in determining intraoperative strategy.
