Abstract:
Objective To assess the clinical value of laparoscopic colorectal resection combined with simultaneous radiofrequency ablation for liver metastases.Methods Twenty-two patients with colorectal cancer and synchronous liver metastases were treated by laparoscopie colorectal resection and simultaneous radiofrequency ablation(RFA)in Third People's Hospital of Chengdu from December 2001 to July 2006.Areas of colliquative necrosis were detected by contrast-enhanced computed tomography postoperatively.The outcomes were analyzed by chi-square test.Results Of all patients,8 had muhiple liver metastases,16 had complications.Thirty-one liver metastases were treated by RFA,and no complication oecurred.The mean postoperative hospital stay was(14±5)days,and there was no perioperative death.Five of the 22 patients were identified as incomplete ablation of the tumor,and the RFA was reperformed.The recurrence of liver metastases in the RFA necrotic zone was observed in 4 patients,and RFA was reperformed on 2 of them.Six patients died,and 2 of them died of liver metastases recurrence in the RFA necrotic zone.The recurrence rate of liver metastases and mortality was 18%(4/22)and 27%(6/22),respectively.The recurrence rate of patients with the diameter of the metastatic lession≥2.0 cm was significantly higher than those with the diameter of the metastatic lession＜2.0 cm(x2=5.867,P＜0.05).Conclusions Laparoseopie colorectal resection combined with simultaneous RFA provide a curative opportunity for colorectal cancer patients who are old and have multiple liver metastases,complications,poor tolerance of operation,and for patients whose tumors are difficult to resect.
