Laparoendoscopic single-site radical cystectomy and urinary diversion: initial experience using homemade single-port device / 中华泌尿外科杂志

ABSTRACT

Objective We report our initial experience with laparoendoscopic single-site surgery (LESS) for radical cystectomy and urinary diversion performed by a single surgeon using homemade singleport device.Methods From December 2010 and April 2011,7 LESS radical cystectomy were performed using a home-made single-port device composed of an inverted cone device of polycarbonate and a powderfree surgical glove.7 patients were all male,mean age was 66 (54-81) years and mean BMI (Body mass index) was 23.1 (20.9-25.3) kg/m2.The port was placed into a 5 cm periumbilical skin incision.The conventional laparoscope and laparoscopic instruments were inserted through the single-port.No additional ports were needed for radical cystectomy and bilateral standard pelvic lymphadenectomy.Cutaneous ureterostomy (3 cases) and ileal conduit urinary diversion (4 cases) were used for patients.Operative time,estimated blood loss,postoperative recovering time,oncologic data and complications were collected and analyzed.Results All the procedures were completed successfully.The mean operative time was 210.1 (155-280) minutes.The estimated blood loss was 300 (100-500) ml.The bowel recovering time 8 (4-12) days and postoperative hospital stay was 20 (13-34) days.One patient required a transfusion of 400 ml red blood cells.The pathologic evaluation revealed that there were one case of pT1N0M0,two of pT2aN0M0,two of pT2bN0M0 and two of pT3aN0M0.The high grade tumor in 4 cases and low grade in 3 cases.The surgical margins were negative in all the patients.All patients were node negative.After the operations,one case had a small bowel obstruction after three days and was treated by abrosia,fluid infusion and gastrointestinal decompression.Another patient died of cardiac disease at first day postoperative.Conclusions In our experience,LESS for radical cystectomy could be clinically feasible for selected patients,but it requires the learning curve.
