The aim of the current study is to compare two surgical approaches for the resection of left-sided obstructive colon cancer: the single-stage emergency resection (control group) and the two-stage bridge-to-surgery procedure (intervention group). Both groups will undergo curative hemicolectomy, including tumor resection and lymph node dissection. International guidelines provide varying recommendations, with 42% advocating emergency surgery and 47% suggesting either emergency surgery or stenting as bridge-to-surgery. Primary resection with or without anastomosis is the most commonly recommended procedure [While the BTS approach can improve the patient’s general condition during resection, it also prolongs the time-to-surgery (TTS). Prolonged TTS may have an impact on cancer survival. Studies by Satish et al. and Kaltenmeier et al. have presented conflicting results, with Satish et al. suggesting that extended TTS (> 21–30 days) is associated with a lower adjusted risk of death [To address this potential issue, our study design incorporates TTS as a secondary end point and evaluate its association with cancer-specific factors, such as cancer survival.
