To explore the safety, feasibility and clinical application value of "three-port method" laparoscopic surgery in the treatment of acute sigmoid colon perforation.

The clinical data of 46 patients with sigmoid colon perforation from September 2016 to March 2025 were retrospectively analyzed. The patients were divided into the control group (n=23) and the observation group (n=23) according to different surgical methods. The observation group underwent "three-port method" laparoscopic partial sigmoid colon resection + colostomy, while the control group underwent open surgery for partial sigmoid colon resection + colostomy. Data were processed using SPSS 22.0 statistical software. Quantitative data such as perioperative indicators were expressed as (±s), and t tests were performed. The incidence of postoperative complications was expressed as [cases (%)], and chi-square tests were conducted. P<0.05 was considered statistically significant.

There was no statistically significant difference in intraoperative blood loss and operation time between the two groups (P>0.05). In terms of postoperative time, postoperative hospital stay, postoperative standing time, incision infection and postoperative analgesia, the observation group was significantly better than the control group, and the differences between the two groups were statistically significant (P<0.05). There was no statistically significant difference in preoperative CRP index values between the two groups (P>0.05), but there was a statistically significant difference in CRP index values 3 days after surgery (P<0.05).

Compared with traditional open surgery, the "three-port method" laparoscopic surgery also has safety and operability, and has obvious advantages in postoperative recovery, postoperative pain and incision healing. It is worthy of clinical application and promotion.
