[Tubal repermeabilisation after sterilisation. Techniques and results (author's transl)]

Requests for repermeabilisation surgery, previously rare, are becoming more common. The indications for reparative surgery are analysed. Microsurgery is possible when the length of the remaining tube us adequate, more than 5 cm, and the ampulla undamaged. It is made difficult when the initial sterilisation procedure has destroyed too long a segment of the tube: electrocoagulation, resection of a long loop of tube. It is impossible when the ampulla and the adjacent portion of the tube have been damaged. Microsurgical techniques certainly improve the results of reparative surgery. After end-to-end anastomosis of the medial half of the tube, 60 to 75% of pregnancies going to term are obtained, and more than 90% secondary permeability. New methods for surgical sterilisation such as clips or rings should make it possible to achieve even better results in the future.
