Electrophysiology of the rabbit oviduct following tubal microsurgery.
The ability of tuboplastic microsurgery to restore electrical continuity across an anastomosis site was investigated in the rabbit. Three to six weeks following transection and end-to-end anastomosis of the tubal ampulla or isthmus, the pattern of electrical activity adjacent to and across the anastomosis site was examined. Recordings were made in vitro using arrays of closely spaced suction electrodes 68 to 72 hours after an ovulating dose of human chorionic gonadotropin. The pattern of electrical activity across anastomosis sites was not significantly different from corresponding portions of unoperated control oviducts. Microsurgical anastomosis restored electrical continuity between anastomosed segments in both the ampulla and isthmus.

[A new technic using polyethylene tubing in oviduct occlusion].
To preserve the tubal patency after tuboplasty the polyethylen prosthesis remains without passing the intramural part of the tube inserted into the ampulla of the tube only ewith a lenght of 3 to 5cm- avoiding decubitus or any other instrumental damage on the tubal lining. The correct insertion of the prosthesis as well as of the tubal patency may be controlled by instillation of a methylen blue solution. After removing the prosthesis the tubal patency would be preserved by hydropertubation with a solution containing antibiotics.

[Reanastomosis of the rabbit fallopian tube with fibrinogen concentrate].
In order to investigate the use of fibrin glue in reconstructive surgery of the oviduct, tubal reanastomosis was performed with homologous fibrinogen concentrate in 26 rabbits. The contralateral tube was clamped. The pregnancy rate was 25%. No adhesions were seen in the area of the anastomosis on examination of the abdomen 3 months after operation.
Needle salpingoneostomy: an atraumatic surgical technique to correct a terminal obstruction of the tubes.
In 50 cases operated on restorative tubal surgery was performed applying an atraumatic technique with a fine needle to create a new opening of the ostium. Resection of the terminal part of the tube was avoided and an extraversion of the ostium fibria was accomplished by careful manipulation. Neither electrocautery nor hydrotubation was used during the operation. Our results were the following: 1. Thirteen (13) cases with intrauterine pregnancy. Twenty-nine (29) cases with viable tubal patency. Four (4) cases which a new obstruction. Four (4) cases which have not returned for re-examination 1.

[Racket-shaped tubal-uterine anastomosis. Technic and results].
Proximal tubal lesions that are discovered when a case of sterility is being worked out are polymorphic in nature and they are variable in extent. Fortunately it is rare that a proximal tubal lesion should involve the whole interstitial portion and the uterine os of the tube. This is why many surgeons have taken up the method of tubo-uterine implantation advocated by Palmer. Salat-Baroux and Cornier published a paper on microsurgical tubo-interine implantation in 1979. We since 1978 have been carrying out a technique of tubo-uterine anastomosis in raquette shape (mostly isthmo-uterine). This is described in detail in this article. The first results on 32 anastomose carried out in 23 patients who were operated on of whom 17 cases had pure cornual lesions and 6 cases bipolar lesions seem to be encouraging with a patency rate 6 months later of 69% and a rate of intra-uterine pregnancy of 23.2% (0.10-0.41) at 12-18 months and 31.1% (0.14-0.56) at 18-24 months (using an actuarial method). Up to now we have not had an extra-uterine pregnancy near the site of suture. Our technique seems to us to give a worthwhile alternative microsurgical method to implantation in interstitial lesions that are widespread and deep.
