ABSTRACT Objectives: To discuss the feasibility and efficacy of a laparoscopic vessel blocking forceps in laparoscopic inferior vena cava (IVC) thrombectomy (1–3). Materials and methods: The patient was secured in a left lateral decubitus position. The surgical field was built with 4-trocar. The laparoscopic vessel blocking forceps was used to block the IVC partially. With the help of the forceps, we completed a retroperitoneal laparoscopic radical nephrectomy and IVC thrombectomy. Results: The patient was a 73-year-old female. The tumor was located on the right side. Based on the preoperative radiology examination, the tumor thrombus extended from the right renal vein into the IVC, and the cephalic extent of tumor thrombus was 1.6cm above the renal vein. The preoperative stage was T3b, and the Mayo grade of the tumor thrombus was grade I. The operation was successfully completed without conversion to open surgery. The operation time was 159 minutes, and the estimated blood loss was about 50ml. No blood transfusion was needed. The postoperative hospital stay was 10 days. No operation related complication was observed. Postoperative pathology showed diffusely poor differentiated carcinoma, and the pathological stage was T3bN0. Conclusion: The laparoscopic vascular blocking forceps can clamp vessels without damaging the vessels. Vascular blocking forceps is suitable for laparoscopic surgical field. We recommend such a vascular blocking forceps for laparoscopic thrombectomy in patients with renal carcinoma and Mayo grade 0-I tumor thrombus. It may be used to clamp other blood vessels temporarily or control bleeding during laparoscopy in the future.

ABSTRACT Purpose To investigate the incidence and pathologic characteristics of prostate cancer (PCa) incidentally discovered at the time of radical cystectomy and its impact on overall survival. Materials and Methods A single center retrospective study of 762 male patients who underwent radical cystoprostatectomy from Jan 1994 to Dec 2012. Results Of all included patients, 132 (17.3%) were found to have PCa. Patients with incidental PCa had a significantly higher mean age (69.2 vs. 62.2 years, P=0.015). Among the 132 patients with PCa, prostate specific antigen (PSA) analysis was available in 76 patients (57.6%), with a median value of 1.06ng/mL, and 61 (80.3%) patients had a PSA value below 4ng/mL. Four hundred and thirty-six patients (57.1%) were successfully followed, with a median duration of 46.5 months. The overall 5-year survival rate was 62.1%, and the 5-year cancer–specific survival rate was 72%. PCa recurrence was defined by two consecutive PSA values of >0.2 ng/mL and rising, and no PCa recurrence occurred. According to a univariate analyses, incidental PCa was not associated with cancer-specific survival (P=0.192) or overall survival (P=0.493). According to univariate analyses, the overall survival of patients with PCa was not associated with prostate cancer staging, PSA value, or Gleason score (All P values>0.05). Conclusions Prostate cancer incidentally discovered at the time of radical cystectomy does not decrease overall survival. Patients with incidental PCa were older than those without. The PSA value before operation is not helpful for predicting incidental prostate cancers.
