Abstract

Abstract Background and Purpose: The recent literature has questioned the infectious risk of natural orifice translumenal endoscopic surgery (NOTES). The need for a clean portal of entry may be important to minimize peritoneal contamination after NOTES. Our study examines the resultant microbial contamination of the human peritoneum after transvesical incision and exposure of the abdomen to bladder contents during robot-assisted laparoscopic prostatectomy (RALP) to better understand the potential for infection in transvesical NOTES. Patients and Methods: Sixty consecutive men undergoing RALP for clinically localized prostate adenocarcinoma from January to May 2008 were prospectively studied as part of a database approved by an Institutional Review Board. The patient's preoperative urine microscopy values, complete blood cell count, and prostate-specific antigen (PSA) levels were recorded, along with the total length of time the cystotomy was open to the peritoneum. Intraoperative samplings of peritoneal f...
