Abstract
PDF - Purpose
In 2019, we reported a novel nomogram to predict lymph node metastasis (LNM) in T1 colorectal cancer. Herein, we conducted a survey-based study to evaluate the clinical utility of this nomogram in determining the need for additional surgery after endoscopic resection for high-risk T1 colorectal cancer.
Methods
A survey was conducted among 77 members of the Korean Society of Coloproctology and 25 members of the Korean Society of Gastrointestinal Endoscopy. The survey assessed decision-making regarding additional surgery after endoscopic resection for high-risk T1 colorectal cancer according to various predicted LNM rates (3%, 10%, and 27%) and tumor locations (anal verge [AV] 2, 7, and 25 cm). Additionally, participants provided feedback regarding the reliability, usefulness, and potential adoptability of the prediction model in patient counseling.
Results
Of the 2,314 surveys distributed, 102 responses were analyzed. A trend was observed in which tumors located closer to the anus and associated with a lower predicted risk of LNM were less likely to lead respondents to opt for surgery (e.g., AV 2 cm and 3% of predicted LNM risk, 21.6% opt for surgery vs. AV 25 cm and 27% of predicted LNM risk, 98.0% opt for surgery). Additionally, 94.1% of the respondents reported that the prediction model would be helpful in clinical decision-making and patient counseling.
Conclusion
Our findings suggest that the nomogram is an effective and reliable tool for guiding treatment strategies and enhancing consultations in patients with T1 colorectal cancer.

- Purpose
Colorectal anastomotic leakage (AL) is a life-threatening complication, which increases morbidity, hospital stay and cost of treatment. The aim of this study is to identify risk factors, including intraoperative indocyanine green fluorescence angiography (ICG FA), associated with the leak of stapled colorectal anastomosis.
Methods
Four hundred twenty-nine consecutive patients underwent surgery between 2017 and 2019 for benign (n=10, 2.3%) or malignant (n=419, 97.7%) and rectal (n=349, 81.4%) or distal sigmoid (n=80, 18.6%) lesions with double-stapling technique reconstruction were included into retrospective study. Univariate analysis and multivariate logistic regression of the tumor-, patient- and treatment-related risk factors of AL was performed.
Results
An AL developed in 52 patients (12.1%). In multivariate analysis following variables were independently associated with AL; male sex (odds ratio [OR], 3.8; 95% confidence interval [CI], 1.9−7.7; P<0.01), anastomosis at ≤6.5 cm from anal verge (OR, 3.1; 95% CI, 1.3−7.5; P=0.01), and age of ≤62.5 years (OR, 2.1; 95% CI, 1.1−4.1; P=0.03). ICG FA was found as independent factor reducing colorectal AL rate (OR, 0.4; 95% CI, 0.2−0.8; P=0.02). A nomogram with high discriminative ability (concordance index, 0.81) was created.
Conclusion
ICG FA is a modifiable surgery-related risk factor associated with a decrease of colorectal AL rate. A suggested nomogram, which takes into consideration ICG FA, might be helpful to identify the individual risk of AL. -
