Abstract
Background: To explore the clinical efficacy of natural orifice specimen extraction surgery (NOSES) combined with transanal endoscopic operations (TEOs) to remove specimens from the anus for laparoscopic radical resection of colorectal cancer. Methods: From January 2014 to May 2020, 120 colorectal cancer patients were selected as study samples, including 60 cases who underwent NOSES laparoscopic radical resection of colorectal cancer (experimental group) and 60 cases who underwent traditional laparoscopic radical resection of colorectal cancer (control group). The basic preoperative conditions, operative time, intraoperative blood loss, lymph node dissection, postoperative hospitalization time, postoperative exhaust and defecation time, postoperative anal function, and postoperative complications were analyzed retrospectively. Results: Sleep quality score (6.26 ± 1.16), pain score (2.95 ± 0.79), and hospitalization time (11.55 ± 3.79 days) were better than those for the control group (P < .05). There were no positive cases of incisal margin in both groups. Gastrointestinal function recovery time, blood loss, lymph node dissection, and postoperative complications were not statistically significant (P > .05). Conclusion: NOSES combined with TEOs has the advantages of less trauma, quick postoperative recovery, and low psychological pressure, so it is worth popularizing.
