Author contributions: Zhou X and Ma D designed the research study; Zhou X, Ma D, and Chen J conducted the animal experiments; Zhou X, He YX, and Liu JQ conducted the in vitro experiments; Jin J, Wang YF, and Yang F was performed data analysis; Zhou X and Ma D were responsible for the visualization of the data; Zhou X wrote the manuscript; Wang HL and Li Z edited the manuscript; Ma D, Chen J, and Li Z provided foundational support for the study. Zhou X and Ma D contributed equally to this work as co-first authors. We propose Chen J and Li Z as co-corresponding authors due to their equal contributions in experimental design, research execution, and funding support. Our rationale is as follows: (1) Experimental design: Li Z conducted thorough literature research and preliminary experiments to assess the potential of Kangfuxin solution for esophageal stenosis following endoscopic submucosal dissection. Simultaneously, Chen J, leveraging his clinical experience, emphasized the use of a full circumferential endoscopic submucosal dissection (ESD) model to enhance the clinical relevance of our findings; (2) Research procedure: This complex procedure required high clinical proficiency. Professors Chen J and Li Z jointly performed all ESD operations with a strict adherence to animal welfare regulations, both taking on critical regulatory roles throughout the study; and (3) Funding support: This research was funded by Chen J (No. 2020YFS0376) and Li Z (No. 2022-CXTD-01), which was essential for procuring experimental animals and reagents. In conclusion, this study merges traditional Chinese and Western medicine approaches to address esophageal stenosis post-ESD. The diverse expertise of Chen J and Li Z enriches our research, and the authors unanimously support their designation as co-corresponding authors.

Core Tip
Core Tip: This study investigated the therapeutic effects and mechanisms of Kangfuxin solution (KFX) on esophageal stenosis following endoscopic submucosal dissection (ESD). Pigs underwent full circumferential ESD and received KFX treatment for 21 days. Endoscopic examinations assessed esophageal repair, while the expression of α-smooth muscle actin-2, fibronectin, and collagen I was evaluated. Profibrotic signaling was analyzed, including transforming growth factor (TGF)-β1, Smad2/3, and phosphor-smad2/3. In vitro, TGF-β1 induced a fibrotic microenvironment in primary esophageal fibroblasts, and KFX treatment reduced the expression of fibrotic markers in these cells.
