With the increased number of female patients seeking sterilization and the good chance of successful reversal using modern microsurgical techniques, it can be anticipated there will be a rise in the number of patients requesting reversal of sterilization.
To achieve higher live birth rates and lower ectopic pregnancy rates after reversing female sterilization, a cluster of techniques referred to as microsurgery have been adopted.
Microsurgery usually consists of a combination of the multiple techniques including use of magnification, accurate approximation of tubal segments and placement of sutures, electro cauterization to minimize bleeding, special care to avoid leaving particles of foreign matter in the operating field, use of fine gauze, non-tissue-reactive suture material and fine needles, and constant irrigation of the operative site.
The chief purpose of magnification is to assure that all pathological tissue on the fallopian tubes is found and removed and, in conjunction with accurate approximation and suturing, that a patent, functional tube is produced.
The chief purpose of the other measures is to avoid the formation of adhesions, which may kink or block the tube, preventing or impeding ovum transport.
