Parkland and Irving Methods
The Parkland tubal ligation technique falls into the category of tubal ligation and resection. The Parkland procedure involves tying two non-absorbable ligatures around the fallopian tube in its proximal to middle segment and then cutting out the tubal segment between the ligatures.
The end result is similar to the Pomeroy method of tubal ligation. Two healthy tubal segments remain that can be rejoined by tubal reversal microsurgery. Two-thirds of women with a Parkland tubal ligation become pregnant following tubal reversal surgery.
Tubal ligation by the Irving method starts by placing two ligatures around the fallopian tube in its proximal to mid-segment and removing the tubal segment between the two ligatures. Then, the tied end of the segment of fallopian tube attached to the uterus is sutured into the back side of the uterus, and the other tied end is buried in the connective tissue underlying the fallopian tube.
This is much different than other types of tubal ligations. There is very little normal tube left to repair and success rates are very poor. Patients having an Irving procedure are strongly encouraged to proceed with IVF. If not, they should at least have a screening laparoscopy to evaluate the tubal lengths remaining for repair.
