To investigate the efficacy of single aperture plus one aperture laparoscopic surgery (SILS+1) versus traditional laparoscopic surgery in the treatment of sigmoid carcinoma.

Data of 86 patients with sigmoid carcinoma from March 2019 to May 2021 were retrospectively analyzed and divided into two groups according to different operation methods. Study group (n= 40, SILS+1 surgery) and control group (n=46, traditional 5-hole laparoscopic surgery). SPSS 19.0 software was used for statistical analysis. Measurement data such as perioperative indicators, pathological differences of postoperative specimens and inflammatory indicators before and after surgery were expressed with (). Independent sample t test was used for comparison between groups.

The total incision length, first time of getting out of bed, first defecation time and postoperative hospitalization time in the study group were better than those in the control group (P < 0.05). There was no difference in the pathological status of postoperative specimens between the two groups (P > 0.05). C-reactive protein and tumor necrosis factor α were increased in all patients after operation, but the increases were more significant in control group (P < 0.05). One year after surgery, there was no difference in overall survival rate and recurrence rate between the two groups (P > 0.05).

Single-hole plus one-hole laparoscopic surgery can not only achieve the same radical curative effect as traditional laparoscopic surgery, but also reduce the inflammatory response of the body, thus speeding up the recovery of patients, and does not affect the prognosis of patients, which is worthy of clinical promotion and application.
