ORSO, Ivan R B et al. Vesico-appendiceal fistula in a mucinous adenocarcinoma of the appendix. ABCD, arq. bras. cir. dig. [online]. 2008, vol.21, n.1, pp. 44-46. ISSN 0102-6720. http://dx.doi.org/10.1590/S0102-67202008000100010.
BACKGOUND: A rare case of vesicoappendiceal fistula secondary to mucinous adenocarcinoma of the appendix is presented. CASE REPORT: A 62-year-old man with a one year history of recurrent urinary tract infections. After two months he developed pneumaturia and fecaluria. An abdominal and pelvic computed tomography demonstrated a trans-mural mass in the posterior wall of the bladder with a vesicoenteric fistula leading to the terminal ileum. Laparotomy revealed a tumor arising from the appendix contiguous with the bladder posterior wall. The bladder was opened and a large fistula and tumor on the posterior bladder wall near the trigone was identified. Frozen pathological analysis showed a mucinous adenocarcinoma. En-bloc right hemicolectomy and partial cystectomy, preserving bladder trigone was performed. After manipulating the tumor, grossly leakage of mucinous materials occurred into the pelvic cavity. A peritoneal washing with a mytomicin solution at 42º C was then performed, to prevent peritoneal seeding. The patient had a prolonged postoperative ileus and was discharged at the 15th day. Five months after the procedure the patient was recieving chemotherapy with 5-fluoracil and leucovorin and there was no signs of recurrent disease. CONCLUSION: The presentation with vesico-appendiceal fistula is extremely rare with only a few cases reported in the literature. Knowledge of different types of neoplasm and appropriate treatment allows the surgeon to provide patients optimal care referring to specialized centers whenever appropriate.
