Detailed Description

See above


  • Drug: Docusate
    • Docusate 100mg BID
  • Drug: Bowel medications
    • Docusate 100mg BID Metamucil fiber wafers – 2 wafers daily Miralax 1 packet daily Bisacodyl 1 suppository BID

Arms, Groups and Cohorts

  • Active Comparator: Docusate
    • Docusate is the standard of care regimen
  • Experimental: Bowel medications
    • Docusate, Miralax, Metamucil wafers, Bisacodyl suppository

Clinical Trial Outcome Measures

Primary Measures

  • Time to First Post-op Bowel Movement
    • Time Frame: Within 1 week of surgery
    • The time to first post-operative bowel movement was measured in hours after surgery.

Secondary Measures

  • Pain Level Associated With First Postoperative Bowel Movement
    • Time Frame: Within 1 week of surgery
    • The pain level experienced with the first post-operative bowel movement was recorded and measured on visual analog score with range 0 to 10 in units on scale. 0 being no pain at all. 10 being worst pain.
  • Consistency of First Postoperative Bowel Movement
    • Time Frame: Within 1 week of surgery
    • The consistency of the first post-operative bowel movement was rated using the Bristol Stool Scale. This is a validated scale that is widely used. It is given to patients as a chart. The chart can be seen here: The seven types of stool are: Type 1: Separate hard lumps, like nuts (hard to pass) Type 2: Sausage-shaped, but lumpy Type 3: Like a sausage but with cracks on its surface Type 4: Like a sausage or snake, smooth and soft Type 5: Soft blobs with clear cut edges (passed easily) Type 6: Fluffy pieces with ragged edges, a mushy stool Type 7: Watery, no solid pieces. Entirely liquid
