The efficacy of transcervical recanalization of obstructed postoperative fallopian tubes
1Department of Radiology, LSU School of Medicine, New Orleans, LA 70112, USA.
Abstract:
The efficacy of transcervical recanalization of obstructed postoperative Fallopian tubes was evaluated in 29 patients who were referred for recanalization. Nineteen had strictures at the site of Fallopian tube reconstruction, and five had strictures, three had fistulae, and two had fistulae and strictures at the site of reversal surgery. A 0.014-inch highly flexible guidewire was passed through the obstruction into the ampullary segment, followed by a 1. 1-2.2 Fr bougie catheter to dilate the stricture. After recanalization, the distal tube was studied by selective salpingography. The method was technically successful in 17 of 19 patients with underlying inflammatory disease and resultant postoperative strictures. The tubes remained patent in 12 patients for a period of 12-48 months; three patients conceived, all delivering healthy babies. Significant disease of the distal tubes was present in seven patients. The technique succeeded in three of five patients with postoperative strictures following reversal surgery. One patient subsequently conceived and delivered a healthy baby. The technique failed in all five patients with fistulae complicating reversal surgery. Transcervical recanalization is thus recommended in the management of patients with postoperative strictures with underlying inflammatory obstruction and strictures complicating reversal surgery.
Insights
Transcervical recanalization effectively treated postoperative Fallopian tube strictures, with successful recanalization in most patients. This procedure offers a viable option for restoring tubal patency and improving fertility outcomes.
Area of Science:
- Reproductive Medicine
- Minimally Invasive Gynecological Procedures
Background:
- Postoperative Fallopian tube obstruction can result from reconstruction or reversal surgeries.
- Strictures and fistulae are common complications affecting tubal patency and fertility.
Purpose of the Study:
- To evaluate the efficacy of transcervical recanalization for obstructed postoperative Fallopian tubes.
- To assess the success rates of recanalization in different types of postoperative tubal damage.
Main Methods:
- A 0.014-inch guidewire and 1.1-2.2 Fr bougie catheter were used for dilation.
- Transcervical recanalization was performed on 29 patients with various postoperative tubal obstructions.
- Selective salpingography was used to assess the distal Fallopian tube post-procedure.
Main Results:
- Technical success was achieved in 17 of 19 patients with inflammatory strictures.
- Tubal patency was maintained in 12 patients for 12-48 months; three achieved successful pregnancies.
- The technique succeeded in 3 of 5 patients with reversal surgery strictures, with one pregnancy.
- Recanalization failed in all five patients with fistulae complicating reversal surgery.
Conclusions:
- Transcervical recanalization is recommended for postoperative Fallopian tube strictures, particularly those with underlying inflammatory disease.
- The procedure shows promise for managing strictures following tubal reconstruction and reversal surgery.
- It is less effective for managing fistulae complicating reversal surgery.
