Laparoscopic Colectomy:You’ve Come a Long Way Baby!
• Improved instrumentation
• Improved techniques
• Standardized approach
• Large experience by a few surgeons
• Still not routine
Barriers to Implementation
• Access to cases
• Technique often differs from open approach– Medial vs. lateral– Comfort in major pedicle ligation (aortic
branches)
• Requirements for more than one skilled surgeon
• Time
Skill Sets
• Multi quadrant surgery– Skilled camera operator– Ability to work against the camera
• Colon not always fixed– Tension created by two operators – both
skilled
• Knowledge of energy devices and endo staplers
Other Considerations
• Loss of tactile feedback– Diverticulitis– Crohn’s disease– Location of tumor/polyp
• Learning curve– Surgeon– Surgical Team– Referring Docs
Preparation - The Patient
• Preoperative evaluation– few additional studies necessary
– additional invasive monitoring unusual
• Flexibility of hips and legs
Room Setup
What we hope for…
What we get…
Set Up: The Bed
• Electric bed
• Bean bag
• Velcro bag to bed
• Bottom of bag at break
Set Up: The Patient
• Modified lithotomy
• Minimize hip flexure
• Arms tucked
• Padding for shoulder
Set Up: The Patient
• Minimize hip flexion
• 10o at most
• More flexion may limit access to transverse colon
Even Better
Set Up: The Patient
• Padding for neck and shoulder
• 3” silk around chest to prevent lateral slippage
Set Up: The Room
Preparation - Surgeon: General Recommendations
• Be prepared for the day
• Don’t book too many cases
• Keep your cool
• Pick the easy lay-up
• Find some good help
Preparation - Surgeon: Learning Curve
• Steep (20-50 cases)– Depth perception
– Multiple quadrants
– Reverse angles
– Coordination of team
Operative times
Conversion rates
Conversions – Does it matter
• Conversion – an ugly word
• Increased operative times
• Increase length of stay
• Increase 30 day readmission/morbidity
• Increase cost
Conversions
Conversions
• No difference in outcomes when compared to an open cohort of similar patient
• KEY is to make a decision to ALTERNATE the approach early
Dis Colon Rectum. 2004 Oct;47(10):1680-5
Alternatives to Conversion
• Pfannenstiel incision after:– mobilization of splenic flexure– division of vascular pedicle
• Hand-assisted
laparoscopy– allows tactile sensation– blunt separation
Preparation - Surgeon: Developing a Systematic Approach
• Develop an approach and stick with it
• Initial survey
• Port placement
• Vascular ligation and medial mobilization
• Lateral mobilization
• Extraction and anastomosis
Laparoscopes• 10mm 0o
– Easy orientation– May be inadequate at the flexures
• 10mm 30o
– Better visualization at flexure and pelvis– Disorientation
• Flexible tip lens
Instrumentation
Conclusion
• Don’t wait for the perfect case
• Be prepared
• If you are going to alternate – do it quickly
• Have fun
