Totally Extraperitonealvs
Transabdominal• A proposed study to compare the two routes
of access was abandoned because the transabdominal method was judged superior– more room for dissection– less trouble maintaining pneumoperitoneum– easier to dissect the seminal vesicles– difficult to apply the totally extraperitoneal
method to patients with large prostates

ConclusionsConclusions
• Oncologic results of laparoscopic prostatectomy appear similar to the open procedure given the available early data
• Functional results of laparoscopic prostatectomy are encouraging but patient numbers are as yet too few to make conclusions on potency and continence

ConclusionsConclusions
• Although it can be performed totally extraperitoneally, we recommend the transperitoneal route– provides larger working space avoids excluding
patients based on prostate size– easier to maintain pneumoperitoneum– better visualization posteriorly means safer
dissection of the seminal vesicles and rectum
