Purposes: Postoperative complications are associated with poor overall and cancer-specific survival after resection of various types of cancer, including primary colorectal cancer. However, the oncological impact of surgical site infection (SSI) after liver resection for colorectal liver metastases (CLM) is unclear. The aim of this study was to investigate the oncological impact of SSI after liver resection for CLM.
Methods: We reviewed data from 367 consecutive patients treated by curative liver resection for CLM between 1994 and 2015. Patients who underwent simultaneous resection of colorectal cancer and synchronous liver metastases (n = 86) were excluded from the analysis. Short- and long-term outcomes were analyzed.
Results: SSI developed in 18 (6.4%) of the 281 patients in the analytic cohort (SSI group). The remaining 93.6% (n = 263) did not suffer this complication (no-SSI group). The operative duration was significantly longer in the SSI group than in the No-SSI group (p = 0.002). The overall survival rates 5 years after liver resection for CLM were 33.3% in the SSI group vs. 50.7% in the No-SSI group (p = 0.043). Multivariate analysis indicated that a liver tumor size ≥ 5 cm, R1 resection, and SSI were independently associated with overall survival after liver resection.
Conclusions: SSI after liver resection for CLM is associated with adverse oncological outcomes.

Background: AT-rich interaction domain 4B (ARID4B) is a transcriptional activator that regulates the phosphatidylinositol 3-kinase (PI3K)/AKT pathway in prostate cancer. However, the role of ARID4B in hepatocellular carcinoma (HCC) has remained unclear.
Methods: This study included 162 patients who had undergone primary hepatic resection for HCC between 2008 and 2019.

Digital technologies, such as virtual and augmented reality (VR and AR) are mainly used in the preclinical and clinical phases in neurosurgery and orthopedics. In contrast, they are used less frequently in visceral surgery as the intraoperative deformation is challenging for the clinical use. The application of VR is used successfully particularly in education and training.

Background/aims: We investigated the clinical practice patterns of Korean endoscopists for the endoscopic resection of colorectal polyps.
Methods: From September to November 2021, an online survey was conducted regarding the preferred resection methods for colorectal polyps, and responses were compared with the international guidelines.
Results: Among 246 respondents, those with <4 years, 4-9 years, and ≥10 years of experience in colonoscopy practices accounted for 25.
