To analyze the clinical effect of continuous intradermal suture and modified one-needle method in double ileal stomy during laparoscopic low anterior resection of rectal cancer.

Data of 80 patients with low rectal cancer from January 2021 to December 2022 were retrospectively selected. All patients underwent laparoscopic low anterior resection of rectal cancer plus prophylactic double ileal stomy. They were divided into two groups according to different suture methods. 39 cases in the observation group were completed by intradermal continuous suture, and 41 cases in the control group were completed by improved one-needle method. SPSS 22.0 software was used to process the research data. Measurement data such as perioperative indexes and LARS score were represented by (), and independent sample t-test was performed. Complications and other statistical data were represented by [n (%)] and χ² test was performed. P<0.05 was considered statistically significant.

Operation time and stomy time in observation group were significantly shorter than those in control group (P<0.05). The total incidence of stomation-related complications in the observation group was lower than that in the control group (2.6% vs.14.6%), but the difference was not statistically significant (P>0.05). There was no significant difference in the LARS score 1month and 3 months after stomy between the two groups (P>0.05), but the LARS score 3 months after stomy was significantly lower than that 1 month after surgery (P<0.05).

Continuous intradermal suture and modified one-needle ileal double-cavity stomy are safe and effective in the treatment of low rectal cancer by laparoscopic low anterior resection. On the basis of not increasing the incidence of postoperative complications, continuous intradermal suture can significantly shorten the operation time and stomy time, and there is no need for postoperative suture removal, so it is worthy of widespread application.
