Management of a ruptured mucinous mesenteric cyst with hyperthermic intraperitoneal chemotherapy

Mesenteric cysts are rare intra-abdominal cysts that are generally regarded as benign, and the incidence of malignancy is often cited to be 3%. The typical recommendation for treatment is complete excision to minimize recurrence. Excision can be performed laparoscopically, but this can lead to intra-abdominal dissemination of the cyst contents. There has been one case report describing the development of pseudomyxoma peritonei following rupture of a mesenteric cyst. We describe the treatment and outcome of a patient who underwent cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for the treatment of an incompletely resected mucinous cystadenocarcinoma originating from the colonic mesentery.
