Abstract
Background:
Appendicitis is a common surgical disease. There are many problems for the early diagnosis of acute appendicitis in kidney transplant patients; differential diagnosis for acute rejection, limitation in imaging study, problems of immunosuppressant and non-characteristic symptoms.
Methods:
We reviewed medical records and transplant database of 2,947 renal transplant patients between April, 1979 and September, 2009 retrospectively. Patient's characteristics, diagnostic methods for appendicitis and operative/postoperative progresses were analyzed.
Results:
Of the 2,947 renal transplant patients, there were 15 (0.51%, 13 males and 2 females) acute appendicitis patients. Mean age at the diagnosis of appendicitis was 37.2±10.1 years. Fourteen (93.3%) patients suffered from prodromal symptom, such as abdominal pain, direct or rebound tenderness, nausea and vomiting. There were 12 (80%) patients with leukocytosis (WBC count >10,000/μ L). Computed tomography scans were performed in 5 (33.4%) patients for diagnosis. Laparoscopic appendectomies were applied for 8 (53.4%) patients. In pathologic diagnosis, 2 cases were reported as 'non pathologic diagnosis' complications occurred in 2 patients as remnant appendicitis and pancreatitis. However, there was no patient with mortality and renal failure during the hospitalization.
