The goal of this observational study is to evaluate whether different circular stapling devices influence the success of the surgical connection between the bowel ends after colorectal cancer surgery in patients undergoing colorectal resection using different stapling devices. The main question this study aims to answer is whether different circular stapling devices affect the risk of a leak developing at the site where the bowel is reconnected after colorectal cancer surgery. Researchers will compare three types of circular stapling devices commonly used in clinical practice (two-row, three-row, and powered circular staplers) to determine whether they are associated with different risks of leakage at the site where the bowel is reconnected after colorectal cancer surgery. Participants will receive standard medical care. Taking part in this study will not affect their treatment, and no additional procedures, tests, or visits are required as part of the study.

Two-row circular stapler: circular stapling device creating a colorectal anastomosis using two concentric rows of staples. The device is used according to routine clinical practice during colorectal resection with primary anastomosis.
Three-row circular stapler: circular stapling device creating a colorectal anastomosis using three concentric rows of staples with graduated staple heights designed to optimize tissue compression and sealing. The device is used according to routine clinical practice during colorectal resection with primary anastomosis.
Powered circular stapler: electrically powered circular stapling device used to create a colorectal anastomosis. The powered mechanism is designed to standardize tissue compression and stapler firing while reducing operator-dependent variability. The device is used according to routine clinical practice during colorectal resection with primary anastomosis.
Anastomotic leakage
Time frame: From the date of surgery until the first occurrence of anastomotic leakage, assessed up to 30 days after surgery
Postoperative complications
Time frame: From the date of surgery until the first occurrence of any postoperative complications, assessed up to 30 days after surgery
Reintervention rate
Time frame: From the date of surgery until the first reintervention, assessed up to 30 days after index surgery
Postoperative length of stay
Time frame: From date of surgery until the date of hospital discharge, average 1 week
