The disadvantages of laparoscopic surgery are as follows: 1. laparoscopic surgery generally pumps carbon dioxide gas into the abdominal cavity to form a pneumoperitoneum, the establishment of the pneumoperitoneum will lift the diaphragm upward, thus compressing the heart and lungs, and the compliance of the heart and lungs will be reduced, thus reducing pulmonary ventilation and cardiac output. 2. laparoscopic surgery is performed with instruments under the observation of the endoscope, and the instruments are generally long, so a slight inadvertence during the operation may damage In the process of electrodesection, the cavity organs may be burned accidentally, and in serious cases, the cavity organs may be perforated, so laparoscopic surgery requires special care and prudence.
