How is a laparoscopy performed?

　　Laparoscopy generally refers to a laparoscopic examination—a type of endoscopic procedure in which a laparoscope is inserted through the abdominal wall into the abdominal cavity to directly visualize and comprehensively examine the organs within the abdomen and pelvis. The specific steps are as follows:

　　1. The patient lies supine with the head tilted backward as much as possible to facilitate optimal visualization during laparoscopy.

　　2. The abdominal skin is disinfected using iodophor, alcohol, or similar agents, sterile drapes are applied, and general anesthesia is administered via intravenous-inhalation combination anesthesia.

　　3. After anesthesia takes effect, 2–3 small incisions are made near the umbilicus and on both sides of the lower abdomen. A Veress needle is inserted through these incisions to introduce carbon dioxide gas and establish a pneumoperitoneum.

　　4. A trocar is placed into the abdominal cavity, through which the laparoscope is introduced to observe the anatomical structures of abdominal organs, and images are recorded.

　　5. After confirming no internal bleeding or organ damage, the laparoscope is removed, the gas in the abdominal cavity is released, the trocars are withdrawn, and the abdominal incisions are sutured.

　　Laparoscopic examination allows direct observation of abdominal organs for potential abnormalities such as gallstones, appendicitis, ovarian cysts, etc. If any pathology is detected, it is essential to cooperate with the physician for prompt and appropriate treatment.
