title: A randomized, prospective, controlled study of laparoscopic dye studies and selective salpingography as diagnostic tests of fallopian tube patency.
abstract: OBJECTIVE
  To determine and compare the relative merits of laparoscopic dye (LD) studies and selective salpingography (SS) as diagnostic tests of fallopian tube patency.
  
  
  METHODS
  Randomized, prospective, controlled study.
  
  
  METHODS
  University-associated assisted reproduction unit.
  
  
  METHODS
  Two hundred seventy-eight women undergoing investigation of infertility.
  
  
  METHODS
  Allocation to the performance of either LD studies followed by SS or SS followed by LD studies conducted sequentially under general anesthesia.
  
  
  METHODS
  Detection of fallopian tube occlusion, including the site of obstruction and evidence of peritubal or pelvic disease.
  
  
  RESULTS
  When diagnosis was compared by the first test used, 16 (11.9%) of 135 patients had proximal tubal occlusion at LD studies versus 5 (3.6%) of 138 at SS. Twelve (5.6%) of 122 patients had distal tubal occlusion at LD studies versus 14 (10.5%) of 133 at SS. Fifteen (11.1%) of 135 patients had peritubal disease at LD studies versus 3 (2.52%) of 119 at SS. When diagnosis was compared by individual tubes, the results were similar. Among patients who had proximal occlusion and otherwise normal tubes by both methods, endometriosis was present in 72.2%.
  
  
  CONCLUSIONS
  Selective salpingography is a better diagnostic test of proximal tubal occlusion than are LD studies. There is no difference between SS and LD studies as a diagnostic test of distal tubal occlusion. Laparoscopic dye studies are a better diagnostic test for assessing peritubal disease than is SS. There may be an association between endometriosis and proximal tubal occlusion. Selective salpingography and LD studies are complementary investigations of the fallopian tubes.
