After introducing minimally invasive surgery, robotic surgery has been increasingly used in colorectal cancer. However, there is a few prospective study for robotic surgery. The aim of this trial is to evaluate the effectiveness and safety of robotic surgery in mid or low rectal cancer.

Condition Intervention Phase
Rectal Neoplasm Procedure: Robotic surgery Procedure: Laparoscopic surgery Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Clinical Assessment of Laparoscopic and Robotic Surgery for Rectal Cancer - Randomized Phase II Trial

Further study details as provided by Ji Won Park, National Cancer Center, Korea:

Primary Outcome Measures:
  • Quality of mesorectal excision [ Time Frame: 7days after surgery (Pathologic report) ]
    Evaluating the quality of mesorectal excision in rectal specimen according to the criteria suggested by Nagtegaal ID, et al. (J Clin Oncol. 2002;20:1729-34)

Secondary Outcome Measures:
  • Short-term postoperative outcome [ Time Frame: Within postoperative 30 days ]
  • Sexual and urinary function, Quality of life, Anorectal function [ Time Frame: Baseline, postop 3 weeks, 3months, 12 months, 24 months, 36 months ]
    IIEF, FSFI, IPSS, EORTC C30, CR38, FISI, MSKCC bowel fuction tool, Manometry

  • Long-term outcome [ Time Frame: Postoperative 36 months ]
    3 year disese-free survival
