Purpose: We aimed to evaluate the precision of preoperative colonoscopic tattooing and intraoperative colonoscopic tumor localization in determining distal surgical margins for leftsided colorectal cancer surgery. Methods: This retrospective study included 30 patients who underwent laparoscopic colorectal surgery, preoperative colonoscopic tattooing, and intraoperative colonoscopic localization for colorectal cancer at our center between July 2020 and March 2024. Clinical data were collected, and the precision of these methods was assessed by measuring the differences between the target resection margin and the actual pathological resection margin. Results: In four patient cases, the indocyanine green tattoo was not visible in the laparoscopic surgical field. The average stained length of the tattoo was 2.89 cm, with a mean distance of 1.18 cm between the low margin of the tattoo and the cancer. The difference between the target distal resection margin by intraoperative colonoscopic localization and the actual pathological resection margin was 0.88 cm. No complications related to the intraoperative colonoscopy were observed. Conclusion Preoperative tattooing showed limitations, such as spreading and occasional invisibility. Intraoperative colonoscopic localization proved to be an effective method for achieving more precise distal surgical margins in left-sided colorectal cancer surgery.

Purpose: Despite improvements in surgical technology, patients who undergo colorectal emergency surgery still have high mortality and complication rates. This places a high burden on the surgeons and the medical institutions who employ them. Mortality outcomes following emergency colorectal surgery were analyzed and risk factors associated with mortality were identified. Methods: Data from patients who were admitted through the Emergency Room from June 2019 to December 2021 and underwent emergency colorectal surgery performed by a single surgeon were retrospectively analyzed. Surgical and medical records of various clinicopathological factors and the Mannheim peritonitis index (MPI) scores were compared between survivors and non-survivors. Results: During the study period, 164 patients underwent colorectal emergency surgery. Following surgery, 24 patients (14.6%) died during their hospital stay. The American Society of Anesthesiologists Classification, the MPI score, indication of surgery, and comorbid disease were factors which showed statistically significant differences between the survivor and non-survivor groups. In particular, in the patients with an MPI score of ≥ 30, 22 of 49 deaths occurred. Conclusion Patients undergoing emergency colorectal surgery exhibit high postoperative mortality rates. By identifying these patients before surgery, and allocating appropriate surgical and intensive care resources to them, medical resources can be utilized more efficiently, and mortality rates can be reduced.

In recent years, the rise of minimally invasive surgery has driven the development of surgical devices. Indocyanine green (ICG) fluorescence imaging is receiving increased attention in colorectal surgery for improved intraoperative visualization and decision-making. ICG, approved by the U.S. Food and Drug Administration in 1959, rapidly binds to plasma proteins and is primarily intravascular. ICG absorption of near-infrared light (750–800 nm) and emission as fluorescence (830 nm) when bound to tissue proteins enhances deep tissue visualization. Applications include assessing anastomotic perfusion, identifying sentinel lymph nodes, and detecting colorectal cancer metastasis. However, standardized protocols and research on clinical outcomes remain limited. This study explores ICG’s role, advantages, disadvantages, and potential clinical impact in colorectal surgery.
