Intramural-isthmic fallopian tube anastomosis facilitated by the carbon dioxide laser.

Proximal tubal obstruction is encountered in 33% of women with tubal factor infertility. Traditional microsurgery and the most recent transcervical tuboplasty have achieved 20% to 30% intrauterine PR. Microdissection of the intramural segment of the fallopian tube with the CO2 laser, resection of the scarred tissue, and microsurgical tubal reanastomosis has resulted in 100% tubal patency and 71% intrauterine PRs.
