Abstract:

Objective

To study the feasibility and safety of natural orifice specimen extraction surgery (NOSES) in colorectal neoplasms by collecting the NOSES cases in colorectal surgery.

Methods

203 patients with colorectal cancer who underwent NOSES from May 2013 to May 2017 were enrolled. Data were collected including preoperative general data, postoperative pathological data, operative data and follow-up data.

Results

The average age of patients was (58.7±11.9) years, the average BMI was (22.6±3.0) kg/m2, 70.8% of neoplasms located in rectal. Pathological results showed that the proportion of middle differentiated adenocarcinoma was 69.4%, the average number of lymph node count was 12.9±5.1 and the average maximum diameter of tumor was (3.6±1.4) cm. The patients in stage I to IV were 23.2%, 41.4%, 24.1% and 3.4% respectively. 87.2% of the patients were treated with rectal specimen extractions and 12.8% by vaginal extractions. The average operation time was (198.9±55.2) minutes and the average blood loss was (73.7±54.2) mL. The average postoperative exhaust time was (44.5±20.5) hours and the average postoperative feeding time was (63.8±15.5) hours. The average postoperative hospital stay was (12.3±4.1) days and the incidence of complications was 11.9%, only two cases received reoperation in the period of hospitalization. The follow-up data showed that postoperative anal dysfunction accounted for 2.2% of total cases and no vaginal dysfunction was detected.

Conclusion

NOSES in colorectal neoplasms seems to be safe and feasible and the short-term effect of NOSES is good. This technology still need to be explored in clinical practice in the future.
