Laparoscopic surgery is a technique in which several small incisions of 5-10 mm (depending on the complexity of the operation) are made through the abdomen and a 3-5 mm diameter laparoscope and operating instruments are inserted to perform surgical operations from within the abdominal cavity. It is an important hallmark of minimally invasive surgery. Currently more than 80% of abdominal surgeries in children can be performed laparoscopically. What are the advantages of laparoscopic surgery compared to traditional surgery? Let’s look at it from the following two aspects: i. Impact on the child: 1. Less trauma, less pain; 2. Smaller wound, less obvious scar, aesthetic; 3. Quicker postoperative recovery and shorter hospital stay. Second, convenient for the surgeon’s operation: 1, the field of view is magnified (up to 3-8 times), and the image is clear, which facilitates the surgeon’s accurate operation; 2, the observation of the abdominal cavity is comprehensive, and the coexisting lesions in the upper and lower abdomen can be dealt with simultaneously; 3, it is convenient to reveal the parts that are difficult to be exposed by conventional open surgery, such as the posterior bladder area and the subphrenic area. So, what are the disadvantages of laparoscopic surgery? 1, the cost is slightly higher; 2, sometimes the operation takes a little longer, but if operated by a skilled surgeon there is little difference with traditional surgery; 3, some parents have concerns about general anesthesia; 4, doctors need special time to learn to master, not all doctors master the technology.
