LAp: laparoscopic appendectomy. LHIPEC: laparoscopic hyperthermic intraperitoneal chemotherapy. PCI: peritoneal carcinomatosis index. SLL: second look laparotomy. RDF: renal dysfunction improved within 1 week. No.4: port site recurrence was revealed 10 months after LP1PEC. No.8: localized PMP (mucocele).
