“…When the recall rate and accuracy rate are high, the average will be higher. If one of them is low, it will lower the average, and its value will be close to the low number, as shown in Equation (12).…”

“…Transumbilical laparoendoscopic single-site surgery (TU-LESS) is a surgical technique performed using surgical instruments through the pore channel, mainly using the umbilicus to place multiple operating pore channels as well as the operating platform of the laparoscope in the abdomen, which can reduce abdominal infections caused by gastrointestinal tract as well as transapproach surgery, with the characteristics of mild pain, rapid recovery, no earthworm-like scar left in the abdomen, safety, and minimal invasion. In this process, it can also use the natural wrinkle site of the umbilicus to cover the surgical incision, which can meet the requirements of women for abdominal “scarless” cosmetology [ 11 , 12 ]. Compared with traditional multiport laparoscopy, TU-LESS is easier to perform in total hysterectomy, can shorten gastrointestinal recovery time and postoperative ambulation time, and can remove the uterus through a single port at the umbilicus and through an approach in a manner similar to “apple cutting.” “Chopstick effect” between instruments is one reason for prolonged operation time [ 13 , 14 ].…”

This study was aimed at investigating the ultrasound based on deep learning algorithm to evaluate the rehabilitation effect of transumbilical laparoscopic single-site total hysterectomy on pelvic floor function in patients. The bilinear convolutional neural network (BCNN) structure was constructed in the ultrasound imaging system. The spatial transformer network (STN) was used to preserve image information. Two algorithms, BCNN-R and BCNN-S, were proposed to remove sensitive information after ultrasonic image processing, and then, subtle features of the image were identified and classified. 80 patients undergoing transumbilical laparoscopic single-site total hysterectomy in hospital were randomly divided into a control group and a treatment group, with 40 cases in each group. In the control group, conventional ultrasound was used to assess the image of pelvic floor function in patients undergoing laparoendoscopic single-site surgery (LESS); in the observation group, ultrasound based on deep learning algorithm was used. The postoperative incision pain score, average postoperative anus exhaust time, average hospital stay, and postoperative satisfaction of the two groups were evaluated, respectively. The highest accuracy of constructed network BCNN-S was 88.98%; the highest recall rate of BCNN-R was 88.51%; the highest accuracy rate of BCNN-R was 97.34%. The operation time, intraoperative blood loss, and exhaust time were similar between the two groups, and the difference had no statistical significance ( P > 0.05 ). The numerical rating scale (NRS) scores were compared, the observation group had less pain, the difference between the two groups had statistical significance ( P < 0.05 ), and the postoperative recovery was good. The BCNN based on deep learning can realize the imaging of the uterus by ultrasound and realize the evaluation of pelvic floor function, and the probability of pelvic floor dysfunction is small, which is worthy of clinical promotion.

“…We previously reported an innovative TU-LESS extraperitoneal approach for lymphadenectomy, which leads to easier access to the para-aortic region and achieve enhanced recovery for cancer patients to shorten the timeframe to receive adjuvant therapy [13]. Furthermore, due to the smaller incision size, patients usually experienced less pain, faster recovery, fewer incisional complications, earlier passage of feces, earlier out-ofbed mobilization, and shorter hospital stays compared to those with conventional laparoscopy [14].…”

Objective: We accumulated the data to verify the fast recovery effect of transumbilical laparoendoscopic single-site surgery by analyzing the perioperative outcomes of patients with gynecological malignancies in the implementation of ERAS. Design: A retrospective study Setting: A university academic hospital Population or Sample: Patients with gynecological cancer undergoing transumbilical laparoendoscopic single-site surgery (TU-LESS) by a single experienced surgeon. Methods: This was a retrospective consecutive single-center study of patients with gynecological cancer undergoing TU-LESS from November 2017 and January 2022. Main Outcome Measures: The main outcomes were the perioperative outcomes in various surgeries including surgery time, estimated blood loss, length of hospital stay, and complications. Results: 315 gynecologic malignant cases successfully experienced TU-LESS in West China Second Hospital were incorporated, including 195 cervical cancers, 86 endometrial cancers and 34 ovarian cancers. The average age for patients is 47.48 (SD = 8.77). The average operating time and blood loss is 273.71 (SD = 87.12) minutes and 166.87 (SD = 237.09) ml, respectively. The average time for the first passage of flatus is 43.68 (SD = 29.75) hours. The hospitalization is 5.30 (SD = 2.42) days in average. Conclusions: TU-LESS is capable to enhance the recovery of patients who suffer from gynecological malignancies in the implementation of ERAS with less pain, shorter hospitalization and better rehabilitation.

Keywords: ERAS, TU-LESS, gynecology oncology
