The value of hysterosalpingography before reversal of sterilization procedures involving the fallopian tubes

Department of Radiology, Thomas Jefferson University Hospital, Philadelphia, PA 19107.

Knowledge of the length of the uterine end of the fallopian tube and the presence of tubal adhesions and fistulas is important when surgical reversal is undertaken in patients who have had tubal ligation. We retrospectively studied hysterosalpingograms in 127 such patients to determine their value in providing this information. The ligation was performed by using the Pomeroy technique in 57 patients. Sixty-one patients had bipolar electrocautery, six had Falope rings inserted, and three had Hulka clips applied. In all cases, the uterine ends of the tube were visualized to a point of obstruction. The sites of occlusion after Pomeroy ligation were midtubal (46%), cornual (16%), proximal ampullary (16%), proximal isthmic (14%), and intramural (8%). After the electrocautery procedure, the sites of occlusion were proximal isthmic (45%), intramural (20%), midtubal (19%), cornual (15%), and proximal ampullary (1%). When Falope rings and Hulka clips were used, the most frequent site of occlusion was midtubal (50%). Tubal adhesions, consistent with successful occlusion, were detected in 16 patients on the basis of a small confined area of extravasation of contrast material at the site of ligation. Tuboperitoneal fistulas, identified by the presence of contrast material spilled from the uterine end of the tube into the peritoneal cavity, were detected in five patients. Our results show that hysterosalpingography is a useful technique for determining the status of the uterine end of the fallopian tube after ligation when reversal of ligation is planned.
