@entity698 has rarely been reported following solid organ transplantation and never following liver transplantation. We reviewed records of all @entity1 who received solid organ transplants at UCLA between 1989 and 2002 and subsequently underwent appendectomy for presumed @entity697 . Of nearly 8000 transplant @entity1 , 17 (nine male, eight female) subsequently underwent appendectomy for presumed @entity697 . Average age at appendectomy was 37 yrs (range 6-73 yrs). Organ transplants included liver (seven @entity1 ), heart (four), kidney (three), kidney-pancreas (two), and @entity299 (one). The mean interval from transplant to appendectomy was 1064 d (16-2977). Presenting symptoms and signs included @entity490 in 16 @entity1 (94%); @entity1209 in 15 (88%); right lower quadrant tenderness in 16; and @entity491 (WBC > 10 000) in 13 (76%). Mean interval from presentation to appendectomy was 0.94 d (range 0-4). Computed tomography (CT) was performed in 16 @entity1 and showed signs of @entity697 in 15. Open technique was used in all @entity1 , preceded by laparoscopy in one. Pathology showed @entity698 in 15 @entity1 (one with perforation), @entity11534 in one, and a normal appendix in one. Mean duration of hospitalization was 7 d (range 1-20). Complications occurred in four @entity1 (24%) and included @entity6177 requiring percutaneous drainage, @entity4037 , @entity1744 , and @entity811 in one @entity1 each. There were no deaths and no cases of acute rejection during hospitalization. Average length of follow-up was 712 d (range 3-2492). We conclude that @entity698 is relatively rare following solid organ transplantation. CT facilitates prompt diagnosis. The clinical presentation is similar to that of non-transplant @entity1 , but complications are more frequent, and hospitalization is longer.
