Abstract
The patient was a 76-year-old woman who had been pointed out having a vesicoenteric fistula since 4 years earlier. As she had undergone surgery for right inguinal hernia and a tumor was revealed in the right lower quadrant of abdomen on abdominal CT scan, it was likely to be foreign-body granuloma due to the mesh or to be relevant to any tumor of appendix. No increases in tumor makers (CEA and CA19-9) were noted. At laparotomy, a tumor which appeared to be primary appendiceal tumor was present in the right lower quadrant. The tumor had involved the mesh, and further invaded the bladder to form a vesicoenteric fistula. The removal of the tumor involving the ileocecal region was performed with associated partial resection of the bladder. At the same time the mesh was also removed. The histopathological diagnosis of the tumor of appendix was low-grade appendiceal mucinous neoplasm.
Mucocele of appendix is a relatively rare disease, and most rare of all is such a case as the disease has formed a fistula with other organ. This paper presents our experience with a case of mucocele of appendix with vesicoenteric fistula formation involving the mesh after surgery for inguinal hernia, together with a review of the literature.
