Although the weight and condition of the patient are also effective, the operation time is usually around 45 minutes. The time between the start and the end of the surgery is 45 minutes, but patients have a preparation period. After entering the operating room, there is a preparation period for anesthesia first. Then, since these operations are performed with laparoscopic instruments and devices, they have a preparation. A certain amount of time is required for the patient to be fixed on the table. After we start and finish the surgery, there is the wake-up phase. After the patient is awakened at the table, if he has any pain or nausea, he is kept there for a certain period of time to relieve them. After that we go to our room.
