Key result
Current evidence does not conclusively support superiority of three-row over two-row circular staplers in reducing colorectal anastomotic leakage.
Why the study?
Does a three-row circular stapler reduce anastomotic leakage compared to a two-row stapler in colorectal cancer surgery?
Does a three-row circular stapler reduce anastomotic leakage compared to a two-row stapler in colorectal cancer surgery?
Methodological limitations in existing studies prevent conclusive evidence supporting the superiority of three-row over two-row circular staplers for colorectal anastomosis.
This letter comments on a recent study comparing two-row and three-row circular staplers in colorectal cancer surgery. We highlight methodological limitations related to the use of historical controls, evolving perioperative practices, and limited event numbers, which may confound the observed reduction in anastomotic leakage. Current evidence does not conclusively support the superiority of triple-row staplers, underscoring the need for prospective studies using standardized modern protocols.
