The clinical study of making the evidence with application of Da vinci-Robot assisted low anterior resection in rectal cancer

Condition Intervention
Rectal Cancer
Procedure: surgery(robot versus laparoscopy)

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Retrospective
Official Title: The Clinical Study of Making the Evidence With Application of Da Vinci-Robot Assisted Low Anterior Resection in Rectal Cancer

Further study details as provided by Yonsei University:

Primary Outcome Measures:
  • The difference in 1 month between two surgical methods in terms of Bladder function. [ Time Frame: 1 month ]
    The robotic surgery for rectal cancer seemed to be associated with a much earlier recovery of normal voiding and sexual function compared to those of laparoscopic surgery although it needs to be verified by larger prospective comparative studies

Secondary Outcome Measures:
  • The difference in 3 months between two surgical methods in tems of Sexual function. [ Time Frame: 3 months ]
  • The serial change of Bladder and sexual function according to times, in each operation method.

Enrollment: 69
Study Start Date: June 2009
Study Completion Date: March 2010
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
