Purpose: In colorectal cancer surgery, it is important to have accurate resection margins. But, there is difficulty to find lesions in laparoscopic surgery. To reduce surgical errors, many preoperative localizing methods have been introduced. In this study, we aimed to assess the preoperative feasibility and safety of autologous blood tattooing. Methods: From August 2017 to February 2020, a total of 11 patients underwent preoperative colonoscopic autologous blood tattooing. At the start of surgery, the surgeon assessed for the presence of visibility and other complications such as abscess or spillage. The characteristics of patients, outcomes, and complications were collected retrospectively. Results: The study comprised 8 men and 3 women, with an average age of 63 years. Except for one imprecise patient during the surgery, all other 10 patients showed precise visibility, and no localization errors were observed. No complication was observed in all patients. Conclusion: Preoperative autologous blood tattooing is a very useful and safe technique because it has high visibility and no complications. This method does not require additional agents or facilities. Large scale study will be required for standard guidelines.
