A Case of Pseudomyxoma Peritonei Treated with Continuous Hyperthermic Peritoneal Perfusion

We experienced a successful case of pseudomyxoma peritonei treated with continuous hyperthermic peritoneal perfusion (CHPP) after surgery for the purpose of preventing recurrence. A 74-year-old man visited our hospital because of a sensation of fulness in the lower abdomen. He was diagnosed as having pseudomyxoma peritonei due to perforated mucocele of appendix. His primary lesion was resected, and gelatinous mucoid material in the abdominal cavity was removed surgically. Postoperative histological examination revealed a mucinous cystadenocarcimoma of the appendix. After surgery we carried out CHPP. In 1 hour, 10, 000ml of physiologic saline solution heated to 45°C was infused into the peritoneal cavity through a silicon tube placed in the left subphrenic cavity and drained out through tubes placed in the pelvic cavity and right lower quadrant. CHPP was carried out several times within 2 weeks after surgery. There has been no sign of recurrence for more than 5 years after CHPP. Therefore, we think that CHPP is effective in preventing the recurrence of pseudomyxoma peritonei.
