Primary Outcome Measures:
  • Quality of Life [ Time Frame: 2 weeks ]

Secondary Outcome Measures:

Study Completion Date: June 2007
Detailed Description:

A typical laparoscopic gall bladder removal procedure requires placement of a rigid laparoscope through a 1.5-2.5 cm incision in the umbilicus and then 2-3 additional 0.5 cm incisions for additional instrumentation. While post-operative complication rates for this procedure are small, wound infection, particularly of the large incision, is one of the most common post-operative complications. There is also a risk of a post-operative hernia at these incision sites.

A less invasive surgical technique that reduces the size or number of laparoscopic incisions offers the potential clinical benefits of eliminating wound infections, hernias and decreasing post-operative pain following laparoscopic gall bladder removal.
