In which surgical procedure is the pneumoperitoneum artificially created?

The creation of a pneumoperitoneum is a key characteristic of laparoscopy, which is a minimally invasive surgical procedure. During laparoscopy, carbon dioxide gas is introduced into the abdominal cavity to expand it. This space allows the surgeon to view and access the internal organs with greater ease using specialized instruments through small incisions. The pneumoperitoneum provides a clearer operative field and minimizes the risk of injury to surrounding tissues, enhancing the overall safety and effectiveness of the procedure.

While cholecystectomy and appendectomy can also be performed laparoscopically, the specific mention of pneumoperitoneum directly relates to the laparoscopic approach rather than the procedures themselves. Similarly, laparoendoscopy is a term that encompasses various endoscopic techniques but is often associated with using an endoscope for visualization rather than the specific creation of pneumoperitoneum. Therefore, the focus on the artificial creation of pneumoperitoneum clearly identifies laparoscopy as the correct answer.
