ARTICLE HIGHLIGHTS
Research background

Robotic resection using the natural orifice specimen extraction surgery I-type F method (R-NOSES I-F) is a novel minimally invasive surgical strategy for the treatment of lower rectal cancer with robotic resection of rectal cancer and natural oral specimen extraction surgery. But its safety and feasibility are still worth exploring.

Research motivation

To evaluate the safety and feasibility of R-NOSES I-F for the treatment of lower rectal cancer by comparing R-NOSES I-F with traditional robotic lower rectal cancer resection. To provide a new minimally invasive surgical method for the treatment of lower rectal cancer.

Research objectives

To investigate the safety and feasibility of R-NOSES I-F surgery in the treatment of low rectal cancer.

Research methods

We used retrospective analysis to include 22 patients who underwent R-NOSES I-F surgery into the R-NOSES I-F group and 76 patients who underwent robotic low rectal cancer resection (RLRC) surgery into the RLRC group. The clinicopathological data of all enrolled patients were analyzed to compare the postoperative outcomes and prognosis of the two groups.

Research results

Compared with the RLRC group, the R-NOSES I-F group had a lower visual analog scale of pain on day 1 after surgery (1.7 ± 0.7 vs 2.2 ± 0.6, P = 0.003) and a shorter postoperative ventilation time (2.7 ± 0.6 vs 3.5 ± 0.7, P < 0.001). After long-term follow-up, there was no significant difference in local recurrence rate and distant metastasis rate between the two groups (P > 0.05).

Research conclusions

R-NOSES I-F is a safe and effective minimally invasive procedure for the treatment of lower rectal cancer, which has the advantages of relieving pain, promoting gastrointestinal function recovery, and avoiding incision complications.

Research perspectives

The incidence and mortality of rectal cancer are increasing significantly, and it is particularly important to improve the postoperative quality of life of rectal cancer patients, especially those with low-grade rectal cancer, through improved surgical methods. In recent years, the combination of robotic surgery and NOSES has become one of the hot spots in rectal cancer surgery. R-NOSES I-F has the advantages of reducing postoperative pain, promoting gastrointestinal function recovery, reducing abdominal wall dysfunction, and avoiding complications of abdominal wall incision, and has certain cosmetic effects. It is a safe and effective minimally invasive surgical modality for the treatment of low-lying rectal cancer.
