Colorectal cancer (CRC) is one of the most common cancers worldwide13. Among them, more than a third are rectal cancer. Due to the higher postoperative functional requirement and the sophisticated neuro- and fascial anatomy of the pelvis and perineum, the best surgical approach for rectal cancer, especially low or ultralow rectal cancer, is still under great debate. Since its first report in 1979, total mesorectal excision (TME) has been the standard surgical technique for the treatment of resecta...

Since their approval for clinical use by the United States Food and Drug Administration in 2000, da Vinci surgical robots have been increasingly utilized across different surgical specialties1. The robotic surgical system has the advantages of using flexible multijoint arms, a high-quality three-dimensional camera, tremor filtration, and greatly improved ergonomics, which can minimize the invasiveness of the operation and thus making it ideal for complex procedures.
For decades, total mesorectal excision (TME) has been the standard for the treatment of resectable rectal cancer. However, for advanced (T3/T4) rectal cancer located below the peritoneal reflection, lateral pelvic lymph node (LPLN) metastasis is a major cause of local recurrence after surgery2. Clinical evidence clearly shows that lateral pelvic lymph node dissection (LPLND) could significantly reduce the local recurrence rate3. Compared with the open procedure, robot-assisted TME and LPLND have been associated with less blood loss, fewer blood transfusions and fewer postoperative complications4. In addition, the long-term outcomes are not significantly different between the two procedures5. The results of these reports indicate that robot-assisted LPLND may be a feasible modality for locally advanced rectal cancer. However, it should be noted that robot-assisted TME and LPLND are complex procedures and should be performed by an experienced surgeon.
Herein, a standard systematic approach to robot-assisted TME and LPLND is described step by step. This procedure was developed at the center having experience in performing more than three thousand robotic procedures6. In addition, this approach was based on normal anatomical characteristics; rare anatomical variations should be noted.
We present the case of a 64-year-old male patient who had intermittent hematochezia for approximately 3 months. Digital rectal examination revealed that a mass was located on the anterior and right lateral wall of the rectum, 5 cm from the anus. An enhanced computed tomography (CT) scan and endoscopic ultrasound (EUS) revealed lower rectal cancer with internal iliac lymph node metastasis. Colonoscopic biopsy confirmed the presence of moderately differentiated adenocarcinoma. The preoperative evaluation suggested that the clinical stage was cT3N+M0. Accordingly, we decided to perform robot-assisted TME and LPLND. Patient consent was obtained prior to performing these procedures.

robot-assisted total mesorectal excision and lateral pelvic lymph node dissection for locally advanced middle-low rectal cancer

Since their approval for clinical use, da Vinci surgical robots have shown great advantages in gastrointestinal surgical operations, especially in complex procedures. The high-quality 3-D visual, multijoint arm and natural tremor filtration allow the surgeon to expose and dissect more accurately with minimal invasion. Total mesorectal excision is the standard surgical technique for the treatment of resectable rectal cancer. To reduce the lateral recurrence rate, lateral pelvic lymph node dissection can be performed, as it is a safe and feasible procedure for locally advanced middle-low rectal cancer with a high possibility of metastasis to the lateral lymph nodes. However, the complexity of the anatomic structures and the high postoperative complication rate limit its application. Recently, several surgeons have increasingly used robotic techniques for total mesorectal excision and lateral pelvic lymph node dissection. Compared with open and laparoscopic surgery, the robotic technique has several advantages, such as less blood loss, fewer blood transfusions, minimal trauma, shorter postoperative hospitalization, and quicker recovery. A robotic approach is generally regarded as a reasonable alternative for complicated procedures such as lateral pelvic lymph node dissection, although there are a limited number of high-quality prospective randomized controlled studies reporting direct evidence. Here, we provide the detailed steps of robot-assisted total mesorectal excision and lateral pelvic lymph node dissection performed at the First Affiliated Hospital of Xi&#39;an Jiaotong University.

The detailed perioperative information of the case presented in the video is shown in Table 1 and Figure 3. The procedure was performed in April 2019 by the corresponding author using the da Vinci Si Robot system. The estimated blood loss during the operation was 90 mL, and no transfusions were required. Postoperative management adhered to the principles of ERAS. After the first defecation on the 6th day after the operation, we administered a meglumine diatrizoate enema and ...
