End-to-end tubal anastomosis using an absorbable stent.

Using absorbable suture as a stent, end-to-end anastomosis of previously ligated or cauterized fallopian tubes was performed in 15 cases. Luminal patency of at least one fallopian tube has been achieved in all cases, and thus far seven pregnancies have occurred in six cases. The technique for inserting the absorbable suture into the distal and proximal portions of the tube is fully described, and the importance of repeated hydrotubations to maintain tubal patency is emphasized.
