Answer

Modified Pomeroy method

The fallopian tube is then followed back to the mid-isthmic portion, and a loop of tube is elevated with the Babcock clamp. The base of the loop is ligated with 2 ties of 2-0 plain gut suture, holding one suture long with a hemostat to avoid retraction of the tube back into the abdomen after transection (see the image below).

Next, a window is created bluntly in the mesosalpinx within the loop using the tips of the Metzenbaum scissors (see the first image below). Each limb of the tube is then individually cut, leaving an adequate tubal stump proximally and distally to ensure that the cut ends do not slip through the suture (see the second image below).

The tubal segment is routinely sent to surgical pathology for confirmation. While holding onto the hemostat, the cut ends are inspected for the presence of tubal ostia both proximately and distally as well as hemostasis (see the following image). Tension on the suture should be released when observing for hemostasis. The tube is then released back into the abdomen. This procedure is then repeated on the remaining side.
