Population
The population consisted of 39 patients with an average age of 49.28 years (ranged 26-66 years), and 87.18% of the cases were middle-aged females. Their BMI values ranged from 19.15 to 33.87 kg/m2, while the average value was 23.60. Two patients could be diagnosed with obesity. Thirty-four patients have undergone gynaecological procedures before, such as cesarean section, hysteroscopy, myomectomy, hysterectomy, and even primary debulking surgery for malignant gynaecological tumors. When it came to prior abdominal procedures history, the data showed that 84.62% of the patients have received abdominal surgeries including cholecystectomy, appendectomy, and other gynaecological intraperitoneal surgeries. Several patients had other complications, for instance, hypertension and diabetes (Table 1). All of them had no history of smoking or drinking (data not shown).
The cases comprised 13 patients with benign disease and 26 patients with malignant disease. Benign diseases included the following types: deep infiltrating endometriosis, ureterovaginal fistula, huge uterine leiomyoma and angioleiomyoma. Meanwhile, malignant diseases consisted of ovarian cancer, cervical cancer, endometrial cancer and recurrent malignant gynaecological tumors. The average preoperative day of all patients was 10.36 days while average postoperative day was 12.64 days. The average of total hospital stay reached to 23 days, and fluctuated from 7 to 42 days. The reason why hospital stay values changed widely was that we didn’t separate benign and malignant diseases. Simultaneously, operation cost seemed more expensive than common laparoscopy, mean operation cost was about 53,452 yuan. The condition of patients undergone MDT gynaecological surgery was usually complicated, so the hospitalization expense reached to a higher level, about 93,605 yuan. But a review predicted that the high expense of robotic surgeries may still be lower than open surgeries21. All the descriptive values were exhibited in Table 1.
