The Cochrane Database of Systematic Reviews
|November 1, 2001
Summary
This systematic review found insufficient evidence to declare stapled anastomosis superior to handsewn techniques for colorectal surgery. Further research is needed to definitively compare complication rates and patient outcomes between stapled and handsewn methods.
Area of Science:
- Colorectal surgery
- Surgical techniques
- Evidence-based medicine
Background:
- Randomized controlled trials (RCTs) comparing stapled and handsewn colorectal anastomosis have yielded inconclusive results.
- Individual studies often lack the statistical power to demonstrate superiority of either technique.
- A systematic review and pooled analysis are necessary to provide a definitive answer.
Purpose of the Study:
- To compare the safety and effectiveness of stapled versus handsewn colorectal anastomosis.
- To test the hypothesis that stapled techniques reduce complication levels.
Main Methods:
- A comprehensive search of multiple databases (EMBASE, LILACS, MEDLINE, Cochrane) was conducted for relevant RCTs.
- Data from 9 RCTs involving 1233 adult patients undergoing elective colorectal anastomosis were analyzed.
- Outcomes included mortality, anastomotic dehiscence, stricture, hemorrhage, reoperation, wound infection, and hospital stay.
Main Results:
- No significant difference was found in mortality (RD -0.6%) or overall anastomotic dehiscence (RD 0.2%) between stapled and handsewn techniques.
- Stapled anastomosis showed a trend towards higher rates of stricture (RD 4.6%, NNT 17) and reoperation (RD 3.9%).
- Anastomosis duration was shorter with stapled techniques (WMD -7.6 minutes).
Conclusions:
- Current evidence is insufficient to establish the superiority of stapled over handsewn colorectal anastomosis.
- The choice of technique may depend on specific patient factors and surgeon preference.
- Further high-quality RCTs are warranted to clarify the comparative effectiveness and safety.
