The criteria of "inoperability".

Area of Science:

• Surgical Oncology
• Anesthesiology
• Perioperative Medicine

Background:

• The term "inoperable" is often misunderstood in clinical practice.
• Clarification is needed regarding "inoperable" in relation to anesthesia and surgical risk.
• Patient assessment and optimization are crucial for elective surgery.

Purpose of the Study:

• To clarify the medical definition and application of "inoperable".
• To emphasize the importance of perioperative risk stratification and patient optimization.
• To review tools and guidelines for assessing surgical risk in elective cases.

Main Methods:

• Review of literature defining "inoperable" in cancer staging and surgical technicality.
• Discussion of guidelines for perioperative cardiovascular management (ESC/ESA).
• Analysis of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) as a risk prediction tool.

Main Results:

• "Inoperable" does not medically preclude anesthesia; it relates to cancer staging or surgical feasibility.
• The ACS NSQIP program utilizes 21 factors to predict outcomes like death, cardiac complications, pneumonia, and acute kidney injury.
• Guidelines exist for precise perioperative risk stratification and patient management.

Conclusions:

• Anesthesia is medically possible for patients deemed "inoperable" based on staging or technical difficulty.
• Comprehensive preoperative risk assessment and optimization are essential for elective surgery.
• Utilizing established guidelines and prediction tools like ACS NSQIP improves patient outcomes.
