Microscopic versus macroscopic tubal anastomosis in rabbit fallopian tubes

The importance of the operating microscope in rabbit tubal anastomosis was assessed by operating on 36 rabbits, half with the aid of the operating microscope and half with the aid of low-magnification loupes. The surgeons' operating comfort and sense of assuredness that the anastomoses were being done properly were increased by the operating microscope. However, the outcome of the anastomoses as measured by pregnancy rates, adhesion scores, and microscopic pathologic findings were not significantly different in the two groups.
