Slide 2

Improving Patient Centered Outcomes in Pancreatic Surgery

• Develop "personalized" surgical treatment:
  • Modeling of outcomes.
  • Theranostics.
• Re-thinking clinical trial design.
• Explore minimally invasive approach to pancreatic surgery program.

Slide 3

Patient Centered Outcomes in Pancreatic Surgery

• Reduced perioperative morbidity.
• Maintain quality of life.
• Decreased peri-operative blood loss and transfusion.
• Increased rate of adjuvant therapy.

Slide 4

Why develop a minimally invasive approach to Pancreas?

• Pancreatic cancer remains dormant for 10-12 years before clinically detectable?
  • Early detection may allow less invasive surgery to be curative?

Slide 5

Why develop a minimally invasive approach to Pancreas?

• "Prophylactic" pancreatectomy:
  • IPMN = polyp of the pancreas.

Images: Polyps of the pancreas are shown.

Slide 6

Laparoscopic PD

• Adequate for ablative surgery.
• For procedures requiring extensive reconstruction the technique is modified to meet the technological limitations.

• Poor ergonomics for the surgeon.
• Limited range of motion of instruments.
• Two dimensional!
  • Wouldn't do open surgery with one eye.

Slide 7

Robotic Pancreas Resections

• Advantages of Robotic Surgery:
  • Magnification 20x-30x.
  • Near 360 degrees range of motion in instruments.
  • Elimination of tremor / improved dexterity.
  • Stereotactic binocular vision�its 3D like Avatar!

Slide 8

Goals of Robotic Pancreas Program at UPMC

• Major objectives:
  • Reproduce open technique and outcomes.
  • Widely applicable.
  • Quality Assurance.
• Rule out Disadvantages:
  • Equivalent safety?
  • Learning curve and time investment.
• Explore Potential Advantages:
  • Decrease peri-operative morbidity/blood transfusions.
  • Earlier adjuvant chemotherapy.

Slide 10

Robot-Assisted Minimally-Invasive Distal Pancreatectomy Is Superior to the Laparoscopic Technique

Slide 11

Methods

• Retrospective analysis of all minimally-invasive distal pancreatectomies at UPMC between January 2004 and February 2011.
• Compared the peri-operative outcomes of our first 30 RADP to 94 consecutive historical control LDP.

Slide 17

Comparison of Robotic (RADP) and Laparoscopic (LDP) Approach to Distal Pancreatectomy

• Robotic assisted minimally invasive distal pancreatic resection appears comparable to laparoscopic approach in safety and feasibility.
• RADP was associated with decreased frequency of conversion to open, increased number of total Lymph node harvested, higher rate of R0 resections and decreased significant blood loss.
• These data suggest that use of the Robotic Platform may allow more patients to successfully undergo minimally invasive distal pancreatectomy.
• Larger multicenter studies are needed to validate these findings.

Conclusions:

• Robotic assisted Pancreatic resections are currently feasible and safe.
• Evolution of the technique will likely continue making comparative studies difficult.
• Multicenter collaborations necessary to study comparative effectiveness.

  • Pisa Italy.
• Second Annual meeting November 2011.
• Goals:
  • Multicenter prospective database.
  • Standardization of procedures.
  • Comparative effectiveness studies.
