This systematic review and meta-analysis compared single-stapled (SS) versus double-stapled (DS) colorectal anastomosis techniques following anterior resection, evaluating both short-term (perioperative) and functional outcomes.
The review synthesized available comparative data on anastomotic leak rates, stricture, bleeding, and functional bowel outcomes between SS and DS techniques, though specific pooled numerical results are not extractable from the provided abstract alone.
As a meta-analysis, findings are limited by heterogeneity across included studies; functional outcome definitions likely varied across trials; and most included studies may not have been randomized, introducing selection bias.
Surgeons performing anterior resection should weigh anastomotic technique choice (single- vs. double-stapled) in light of this pooled evidence on both complication rates and longer-term bowel function. Review findings can guide shared decision-making, particularly for patients at higher risk of anastomotic complications.
