Direct view of abdominal organs and structures without major surgery◦ endocrine, gastrointestinal, reproductive, and urinary systems

Implementations include:◦Assessing for lesions, tumors, internal bleeding◦ Treating cancer◦Organ removal

Most common laparoscopic procedure = cholecystectomy Over 1 million cholecystectomies per year in US◦ Over 96 % are through laparoscopy

Small incision below navel CO2 is passed through needle through incision◦ Elevates abdominal wall like a dome above organs

Thin, flexible tube inserted through incision Tiny video camera (laparoscope) inserted into tube◦ Produces images on monitor

Instruments are introduced into abdomen via trocars – hollow tubes that prevent CO2 leakage

Shorter recovery time Reduced amount of pain due to:◦ Smaller incisions◦ Less bleeding

Reduced risk of infection due to decreased exposure to external environment

Tighter range of motion, less depth perception Difficult to judge appropriate force on tissue Risks include:◦Misplacement of CO2

◦Organ puncture◦ Injuries from insertion of trocars

Hernias Infection Penetration of blood vessels/bowel
