    Study Notes

    Definition and Terminology

    • Minimally Invasive Surgery (MIS) uses technology to avoid large incisions.
    • Synonyms include endoscopic surgery, laparoscopic surgery, and natural orifice transluminal endoscopic surgery (NOTES).

    MIS Versus Open Surgery

    • MIS procedures generally lead to reduced recovery times and lower pain levels compared to open surgery.

    Endoscopic MIS Instrumentation

    • Endoscopes: Available in flexible, rigid, and semirigid forms; used for both diagnostic and operative purposes.
    • Light Sources: Essential for visibility; should be used with caution to avoid contact with flammable materials.

    Trocar System

    • A trocar system allows safe entry into the abdominal cavity; consists of an obturator and a sleeve (cannula).
    • Steps for insertion: Insert obturator and sleeve, then remove obturator, leaving the sleeve in place.

    Camera Utilization

    • The camera is a non-sterile device requiring draping with a sterile sleeve by the scrub nurse to maintain sterility during surgery.

    Additional Instruments

    • Clip Appliers: Can be disposable or re-usable.
    • Endocatch Retrieval Device: Used for capturing tissues or specimens.
    • Stapling Device: Utilized in various surgical procedures.

    Video Technology Components

    • Essential components include endoscope, light source, camera head, and video monitor; crucial for visualizing surgical field during MIS.

    Robotics in Surgery

    • Utilizes advanced technology to assist in surgical procedures, enhancing precision and control.

    Pneumoperitoneum

    • Created with CO2 gas for better visualization of abdominal structures; typical flow rates are 15-20 liters per minute with pressures of 14-16 mm Hg.

    Establishing Pneumoperitoneum

    • Closed Method: Utilizes a Verres needle to insufflate CO2, confirmed by negative bowel and blood return.
    • Open Method: Requires incision through the umbilicus and placement of a Hasson Trocar for access.

    Safety Considerations

    • Overpressurization can lead to complications such as hypercarbia and decreased cardiac output.
    • Compression on the abdomen or additional gas sources can exacerbate issues.

    Anesthetic Considerations

    • Potential complications include hypothermia, hypoxia, CO2 gas emboli, and pneumoscrotum, which may arise during MIS procedures.
