Recently, an 8-year-old girl was found to have an ovarian cyst during a medical checkup in Shanghai, and the doctor in Shanghai told the parents that she needed surgery to remove it. After many inquiries, the parents learned that Dr. Zhou Xuewu, deputy director of pediatric surgery and associate chief physician of Xuzhou Central Hospital, was very good at single-port laparoscopy, so they brought the child to Dr. Zhou’s expert clinic. After careful examination of the child, Dr. Zhou decided to perform transumbilical laparoscopic removal of the ovarian cyst. After an intense surgery of nearly one hour, the ovarian cyst was successfully removed and the child was able to get out of bed the same day after the surgery. The child is now recovering well and was discharged from the hospital. It is reported that ovarian cysts are not uncommon in adolescent girls and are often found during physical examinations or when there is torsion. Ovarian cysts are prone to rupture and bleeding and torsion, and even ovarian necrosis. Transumbilical approach endoscopic surgery is an internationally advanced minimally invasive surgical procedure that requires only a few millimeters of incision in the belly button, and the patient’s abdomen is scarless after surgery, which is very much in line with modern aesthetic requirements, and the damage to the organism is relatively small, and the patient can recover within a short time after surgery. The operation has less bleeding, less pain, quicker recovery and shorter hospital stay.
