Abstract
Background
Data on anastomotic microcirculation of coloanal anastomoses are contradictory. Therefore, it was the aim of the present study to investigate perianastomotic blood perfusion in a standardized experimental setting comparing three forms of reconstruction using laser fluorescence videography, a new method for the evaluation of microcirculation.
Methods
After a standardised rectal resection in dogs, reconstruction was performed as straight end-to-end (n=6), side-to-end (n=6), or J-pouch (n=6) coloanal anastomosis. Bowel perfusion was evaluated using IC-View laser fluorescence videography.
Results
The perfusion index was significantly reduced in all three groups compared to the reference regions: endto-end anastomosis, median, 93% (range, 63%–136%); side-to-end-anastomosis, 65% (35%–38%); colonic-J-pouch anal anastomosis, 52% (32%–42%); p<0.001).
Conclusions
Straight coloanal anastomoses provide better anastomotic microcirculation after rectal resections than colonic-J-pouch anal anastomoses or side-to-end anastomoses. However this effect does not seem to be decisive for the prevention of anastomotic leaks.
