ObjectiveRecently, minimally invasive therapies for renal cell carcinoma have been devised to minimise operative morbidity yet achieve comparable oncologic and functional outcomes. This video summary of laparoscopic transperitoneal organ-preserving kidney cancer resection shows the procedure from the surgeon's view.Methods
The video and photos show the main steps of the procedure. The results of 40 transperitoneal and retroperitoneal procedures performed during 2001–2005 are discussed. Preoperative preparation includes abdominal computed tomography and ureteral catheterisation. Tumour margins were determined by laparoscopic renal ultrasonography. Vessel control was done by en bloc clamping or solitary clamping of the artery. For optimal macroscopic evaluation of the resection margins, tumour excision was solely done with cold Endoshears followed by pelvicaliceal suture repair and parenchymal closure over surgical bolsters with a biologic haemostatic agent.
Results
In 40 cases, we converted to the open procedure only once. The average patients age was 53 yr and mean tumour size was 26 mm. No patient showed positive surgical margins. The mean warm ischemia time was 21 min. Final histopathology revealed renal clear cell carcinoma as the major cell type followed by papillary renal carcinoma. Two patients required blood transfusion. Estimated mean blood loss was 270 ml. Median time of hospitalisation was 6 d.
Conclusion
Endoscopic partial nephrectomy can be performed by experienced surgeons in selected patients. Tumour location and size and the surgeons’ experience and preference are the main parameters to make the decision of the type of access.
