The situation of demand for surgical conditions is quite high when lymph node resection involved in the surgery type, especially abdominal aortic lymph node dissection, and commonly, the surgeons complained about the interference from the intestine which pushed the investigators to increase the level of neuromuscular blockade close to deep NMB. To avoid the application of deep NMB and promote good surgical conditions for laparoscopic gynecological surgery with lymph nodes resection, the investigators explored other preoperative ways to cooperate with surgeons more harmoniously. It's well known that epidural anesthesia and epidural anesthesia combined with spinal anesthesia have the effect of muscle relaxation which has been applied in clinical practice widely. One study indicated that the Transverse Abdominal Plane (TAP) block could change muscle thickness and achieve the effect of muscle relaxation. It leads investigators to a hypothesis that the sheath of rectus abdominis block combined with transverse abdominal plane block may suppress the signal transmission of abdominal nerve, and may be beneficial to improve surgical conditions.

Primary | the good or optimal percentage of each group based on the surgical rating scale (5-point scale) | The primary outcome was the frequency of the good or optimal rating scale based on a ?ve-point surgical rating scale (SRS) ranging from 1 (extremely poor conditions) to 5 (optimal conditions). | The field of vision was assessed every 15 minutes, from the beginning of the pneumoperitoneum to the end of the pneumoperitoneum. The surgeon gave a score, and the field of vision grade was determined based on the mean value. |
