Prognostic factors of fimbrial microsurgery.
From January 1978 to December 1983, 600 infertile women underwent microsurgery for tubal infertility. Only 257 women with the same extent of distal lesions on both sides or with unilateral occlusion (after contralateral salpingectomy) were considered. Patients were classified in four subgroups on the basis of the extent of occlusion. After fimbrioplasty for occlusion of degree I and salpingostomy for occlusion of degree II, the term pregnancy rate was more than 50%. After salpingostomy for occlusion of degrees III and IV, the term pregnancy rate was, respectively, 25% and 22%. The ectopic pregnancy rate was the highest (12%) after salpingostomy for occlusion of degree IV. After microsurgical salpingolysis, the term pregnancy rate reached 64%, whereas the ectopic pregnancy rate was as low as 2%. Ampullary dilatation, as determined by hysterosalpingography and laparoscopy, influences the postoperative pregnancy rate. Fimbrial microbiopsies were taken, and the ciliated cell percentage was obtained. Results suggest that the ciliation index is a valuable method of prognosis of tubal surgery. In conclusion, the pregnancy rate after distal surgery is related to the tubal morphologic findings: ampullary dilatation, fimbrial ciliated cell percentage, and tubal wall thickness.
