【 摘 要 】

BackgroundTo introduce a novel “three-port” trocar placement technique for laparoscopic radical prostatectomy (LRP) in prostate cancer (PCa) patients.MethodsWe retrospectively reviewed 300 patients with PCa who received surgical treatment between November 2010 and June 2015 at our institution. They were divided into group A, three-port LRP; group B, conventional four-five-port LRP; group C, open RP (ORP); and group D, robotic-assisted RP (RARP). A learning curve was analyzed by dividing patients of group A into the early and late stages.ResultsAll groups were comparable with regard to the preoperative characteristics except for the relatively smaller prostate volume in group A. The three-port LRP operations were performed successfully with only 8 cases of conversion to the conventional LRP. None of any severe complications or conversion to ORP occurred. In group A, the mean operative time (OT) duration was 113.8 min, the mean estimated blood loss (EBL) was 94.2 ml, the mean drainage days was 4.0 days, the mean hospitalization was 5.1 days, and 27.8% of the prostate specimen margins (PSM) were positive. The differences of OT, EBL, drainage days, hospitalization, and transfusion in group A were statistically significant among the majority of the other groups (p < 0.05). After undergoing the early stages of a learning curve analysis in three-port LRP, the EBL was obviously decreased.ConclusionsThree-port LRP is a novel technique that exhibits superior intraoperative advantages to the conventional LRP. Due to its less OT, EBL, drainage days, hospitalization, and transfusion with a shorter learning curve, it should be recommended and popularized in the clinical practice.
