Abstract Introduction The benefits of intracorporeal anastomosis in laparoscopic colorectal cancer surgery remain unclear. Therefore, we aimed to investigate the short‐term postoperative outcomes of intracorporeal anastomosis. Methods We retrospectively analyzed 87 patients who underwent laparoscopic surgery for right‐sided colon tumors using a colon database. Results Of the 87 patients, 23 underwent intracorporeal anastomosis and 64 underwent extracorporeal anastomosis. Intraoperative bleeding, wound length, exhaust gas, preoperative white blood cell count, and C‐reactive protein (postoperative day 1) were higher in the extracorporeal anastomosis group than in the intracorporeal anastomosis group. The incidence of wound infection was higher in the intracorporeal anastomosis group than in the extracorporeal anastomosis group. In the irrigation water bacterial culture collected after anastomosis, the positive group had a higher white blood cell count on postoperative day 1 and higher C‐reactive protein levels on postoperative day 3 than did the negative group. Patients who underwent chemical preparation had lower C‐reactive protein levels on postoperative day 1 than did the group who did not undergo chemical preparation. Conclusion Despite the advantages of intracorporeal anastomosis in terms of wound length and intraoperative bleeding, the risk of infection may increase during the introduction phase. Fever and inflammatory responses are significantly elevated in culture‐positive cases.
