    Study Notes

    Minimally Invasive Surgery

    • Laparoscopic cholecystectomy: a 1-centimeter incision at the umbilicus and two or three other 5-millimeter incisions to extract the gallbladder
    • Advantages: strong cosmetic advantage, less adhesions, faster recovery, and less postoperative pain

    Robotic Surgery

    • Similar to laparoscopy, but uses a robotic platform to remotely control instruments
    • Advantages: improved vision, precision, and quality of movements
    • Potential for integration with artificial intelligence and protocols for automatic identification of anatomical structures and anastomosis

    Preoperative Evaluation

    • Step 3: evaluate the type of surgery and determine if it is low risk
    • Step 4: evaluate the patient's cardiovascular function using the MET score
    • Step 5: investigate underlying cardiac risk index conditions

    Cardiac Risk Index Conditions

    • Pulmonary evaluation: consider smoking, COPD, preoperative sputum production, pneumonia, dyspnoea, and obstructive sleep apnoea
    • Kidney evaluation: consider creatinine level >2 mg/dL and renal dysfunction
    • Medications: beta-blockers, metformin, antithrombotic therapy, and acetylsalicylic acid

    Global Risk Assessment

    • American College of Surgeons' online calculator considers 20 clinical parameters and the type of procedure
    • Predicts patient risk factors, but not perfect due to complexity of parameters

    Frailty

    • A state of reduced physiological capacity and increased susceptibility to disability caused by age-related loss of physical, cognitive, social, and psychological function
    • A multi-factorial event considering age, chronic comorbidity, disability, and social and psychological function

    Prehabilitation

    • Prepares patients in the perioperative setting for better outcomes
    • Includes nutritional assessment and supplementation, smoking cessation, physical exercise programs, and care for cognitive function and stress
    • ERAS protocol reduces the stress response to surgery, while prehabilitation occurs before

    Nutritional Support

    • Improves surgical outcomes
    • Supplementation can be oral, enteral, or parental
    • Immunonutrition reduces postoperative infections
    • 10-14 days of nutrition support recommended for severely malnourished patients

    Prehabilitation

    • Prepares patients in the perioperative setting to have better outcomes in surgery
    • Includes:
      • Nutritional assessment and supplementation
      • Smoking cessation
      • Physical exercise programs
      • Cognitive function and stress management
    • Improving nutritional status can improve surgery outcomes
    • Malnutrition can be solved by giving supplementation (orally, enterally, or parenterally)

    ERAS Protocol

    • Reduces the stress response to surgery
    • Occurs before surgery (preoperative)

    Nutritional Support

    • 10-14 days of nutrition support recommended for severely malnourished patients
    • 7 days of immunonutrition (nutritional formulas aimed to regulate the immune system) recommended for all patients undergoing GI oncological surgery
    • Immunonutrition reduces postoperative infections

    Smoking Cessation

    • High impact on patient outcomes
    • Additional measures for COPD patients: breathing techniques, medications

    Anemia Correction

    • Iron supplementation or erythropoiesis stimulation (if it doesn't interfere with cancer treatment)
    • Blood transfusions only in severe anemia with risk of organ ischemia

    Telehabilitation

    • Used to contact patients remotely to provide prehabilitation and monitor activity and psychological aspects

    Principles of Surgical Oncology

    • Distinction between surgeon and surgical oncologist
    • Grading frailty:
      • Physical frailty (based on S&S: weight loss, exhaustion, weakness, slow walking speed, decreased physical activity)
      • Index frailty (considering cumulative comorbidities and illnesses)

    Frailty Scale (FRAIL)

    • Each affirmative answer to questions is worth 1:
      • Fatigue
      • Resistance
      • Ambulation
      • Illnesses
      • Loss of weight
    • Patient is defined as frail when score is >3

    Index Frailty

    • Consider all comorbidities using a comprehensive geriatric assessment
    • Takes into account functional status, diabetes, history of COPD, history of congestive heart failure and hypertension requiring medication

    Sarcopenia

    • Age-related loss of skeletal muscle mass, muscle strength, and muscle function
    • More than 50% of patients > 80 years old are affected
    • Large percentage of patients of any age with oncological diseases are also affected
    • Associated with more complications, higher mortality, and longer hospital stay

    TNM Staging

    • Prefixes specify characteristics of staging:
      • cTNM: clinical, based on preoperative evaluation
      • pTNM: based on pathology data
      • yTNM: stage after chemo/radiotherapy
      • rTNM: stage for a recurrent tumor
      • aTNM: stage determined at autopsy
      • uTNM: stage based on ultrasound or endoscopic ultrasound
      • mTNM: in case of multiple tumors

    Additional Parameters in TNM

    • G (1-4): tumor grading
    • S (0-3): elevation of serum tumor markers
    • Pn (0-1): perineural invasion
    • L (0-1): lymphatic vessel invasion
    • V (0-2): venous invasion

    Surgery in Diagnosis and Staging

    • Role in diagnosis and staging:
      • Incisional and excisional biopsy
      • Exploratory laparoscopy to find metastases difficult to visualize with imaging

    Prehabilitation

    • Prepares patients in the perioperative setting for better surgical outcomes
    • Includes:
      • Nutritional assessment and supplementation
      • Smoking cessation
      • Physical exercise programs
      • Cognitive function and stress management

    Nutrition and Surgery Outcomes

    • Improving nutritional status can enhance surgery outcomes
    • Malnutrition can be solved by supplementation (orally, enterally, or parenterally)
    • 10-14 days of nutrition support recommended for severely malnourished patients
    • 7 days of immunonutrition recommended for all patients undergoing GI oncological surgery
    • Immunonutrition reduces postoperative infections

    Smoking Cessation and Respiratory Care

    • Smoking cessation has a high impact on surgery outcomes
    • COPD patients may require breathing techniques and medication
    • Telerehabilitation can be used for remote prehabilitation and monitoring

    Anemia and Blood Transfusions

    • Correct anemia with iron supplementation or erythropoiesis stimulation
    • Blood transfusions only considered in severe anemia with risk of organ ischemia

    Surgical Oncology Principles

    • Distinction between surgeon and surgical oncologist
    • Evaluation of surgical risk involves assessing CV function and cardiac risk index conditions

    Cardiovascular Evaluation

    • MET score evaluates metabolic state and energy needed for daily tasks
    • MET score < 4 indicates underlying CV condition
    • Cardiac risk index conditions include unstable coronary disease, decompensated heart failure, and more

    Pulmonary Evaluation

    • Conditions that worsen surgery outcomes include smoking, COPD, and pneumonia
    • Pulmonary rehabilitation reduces pulmonary impact during and after surgery

    Kidney Evaluation

    • Renal dysfunction affects approximately 5% of the adult population
    • Creatinine level >2 mg/dL increases risk of postoperative cardiac complications
