ABSTRACT
Objective:
To investigate the safety and efficacy of the novel single-port surgical robotic surgical system in extraperitoneal urological surgery.Methods:
From February to April 2022, patients was prospectively enrolled who required laparoscopic radical prostatectomy, partial nephrectomy and adrenal tumor resection in urology department. Inclusion criteria were age ≥ 18 years old; BMI 18.5-30 kg/m 2; American Society of Anesthesiologists (ASA) physical status classification system grades 1 to 3; can cooperate with the completion of the visits and related examinations stipulated in the plan, and participate voluntarily clinical trials, and consent or the guardian agrees to sign the informed consent form; tumor indicators meet one of the following surgical treatment indications kidney tumor T 1 stage, single, maximum tumor diameter ≤ 4 cm; prostate cancer, stage ≤ T 2b, preoperative PSA ≤ 20 ng /ml; Gleason score ≤ 7; adrenal tumor diameter ≤ 7 cm, for non-functioning adrenal adenoma, tumor diameter ≥ 3 cm. Exclusion criteria were patients with other malignancies or a history of other malignancies and the investigators believe that they are not suitable for inclusion in this researcher; patients who have received the same type of urological surgery in the past and are not suitable for participating in this study as assessed by the investigators; included Those who have undergone other major surgery within the first 3 months and during the trial period, or who cannot recover from the side effects of any such surgery; syphilis, hepatitis B, HIV infection and carriers; long-term use of anticoagulants or blood system diseases; Unable to use effective contraception during the trial period and other conditions that the investigators deem inappropriate to participate in this trial. All operations were performed by a novel single-port robotic surgical operating system, and all surgical procedures were performed through an extraperitoneal approach. Surgicalmethod:
the surgical system is mainly composed of a remote console including a high-definition display, a surgical equipment trolley, a surgical execution system that accommodates a serpentine robotic arm, and a bendable serpentine robotic arm. In this study, the extraperitoneal approach was used. For radical prostatectomy, the patient was placed in a supine position, a longitudinal incision of about 3 cm was made below the umbilicus, the anterior rectus sheath was incised, the extraperitoneal space was separated, and an operating sheath was placed. A 12 mm trocar is placed between the right McBurney point and the umbilicus as an auxiliary hole. For partial nephrectomy and adrenal tumor resection, the patient is placed in the lateral position, and an 3cm incision is made 2 cm above the iliac crest on the midaxillary line as the main operating hole. The skin, subcutaneous tissue, and muscle were incised to the retroperitoneal cavity, and a 12mm trocar was placed at the level of the anterior superior iliac spine on the anterior axillary line as an auxiliary hole. The operation was performed after connecting each robotic arm. After the operation, the specimen was placed in the specimen bag, and a drainage tube is placed in the auxiliary hole, the specimen was taken out, and the incision was closed in turn. Preoperative basic information, operation time, blood loss, incision size, postoperative complications, preoperative and postoperative PSA score, eGFR index, postoperative pathological information and other perioperative information were collected.Results:
A total of 17 patients were included in this study, including 6 with prostate cancer, 8 with renal tumor, and 3 with adrenal tumor. There were 9 males and 8 females, with an average age of (56.7±14.6) years and a BMI of (23.3±3.4) kg/m 2. The mean operation time of radical prostatectomy was (244.6±35.1) min, the mean operating time of the chief surgeon was (184.0±39.0) min, and the mean blood loss was (36.6±23.8) ml. Postoperative positive margin was found in 2 cases. The average operation time of partial nephrectomy was (189.6±49.4) minutes, the average operating time of the chief surgeon was (115±39.7) minutes, the average blood loss was (12.7±8.3) ml, and the average warm ischemia time was (23.1±10.8) minutes. There was no significant difference in the eGFR index before and after the operation ( P>0.05). The average operation time of adrenalectomy was (177.6±26.9) min, the average operating time of the chief surgeon was (99±20.4) min, and the average blood loss was (11.6±6.2) ml. The overall average operation time of the three surgical methods was (206.9±50.1) min, the overall average operating time of the chief surgeon was (136.5±51.1) min, the overall average blood loss was (21.0±9.2) ml, and the overall average incision size was (3.5±0.5) cm, all added a 12 mm auxiliary channel, and the overall average hospital stay was (8.1±2.7) days. All operations were successfully completed, and there was no conversion to open surgery during the operation, and no operation holes were added. There was no Clavien-Dindo≥grade 3 complication after operation.Conclusions:
The novel single-port robot could safely and effectively perform radical prostatectomy, partial nephrectomy and adrenalectomy which are common in urology through extraperitoneal approach.
