Neoadjuvant chemoradiotherapy (nCRT) for rectal cancer can lead to structural changes in collagen in the tumor microenvironment and increase the risk of postoperative anastomotic stenosis (AS). However, the quantitative relationship between AS and collagen has not been defined. This study is to quantitatively analyze the collagen features in rectal cancer and explore the relationship between the changes of collagen and postoperative anastomotic stenosis after nCRT. ⋯ CS is an independent risk factor for AS in rectal cancer after nCRT. The predictive model based on CS can predict the occurrence of postoperative AS.

The Abbreviated Injury Scale (AIS) is widely used for body region-specific injury severity. The American Association for the Surgery of Trauma Organ Injury Scale (AAST-OIS) provides organ-specific injury severity but is not included in trauma databases. Previous researchers have used AIS as a surrogate for OIS. This study aims to assess AIS-abdomen concordance with AAST-OIS grade for liver and spleen injuries, hypothesizing concordance in terms of severity (grade of OIS and AIS) and patient outcomes. ⋯ AIS should not be used interchangeably with OIS due to lack of concordance. AAST-OIS should be included in trauma databases to facilitate improved organ injury research and quality improvement projects.

Multicenter Study
Global Outcomes Benchmarks in Laparoscopic Liver Surgery for Segments 7 and 8: International Multicenter Analysis.
In recent years, there has been growing interest in laparoscopic liver resection (LLR) and the audit of the results of surgical procedures. The aim of this study was to define reference values for LLR in segments 7 and 8. ⋯ This study shows the need to establish standards for the postoperative outcomes in LLR based on the complexity of the resection and the location of the lesions.
