Which part of the tube is ligated while doing female sterilization by Pomeroy's technique?
Which part of the tube is ligated while doing female sterilization by Pomeroy's technique?
Show Hint
Pomeroy's loop is taken from the mobile mid-portion of the tube, easiest to bring up through a small incision.

- Ampullary
- Isthmo-ampullary
- Interstitial
- Isthmic
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Pomeroy's method is a classic way of tying off the fallopian tubes for permanent contraception, and it depends on picking up a loop of tube that is easy to reach and handle.
Step 2: Key Formula or Approach:
Think about which part of the tube is mobile enough to be lifted into a loop, tied at its base with catgut, and cut off, all through a small incision just above the pubic bone.
Step 3: Detailed Explanation:
The interstitial segment sits inside the uterine wall itself and simply cannot be lifted into a loop, so it is ruled out.
The far ampullary end, near the fimbriae, is thinner and sits further away, making it an awkward choice for this technique.
The mobile mid-portion of the tube, at the isthmo-ampullary junction, is the segment that is classically brought up, looped, tied, and excised in Pomeroy's technique, since it lies close to the usual incision and is easy to handle.
Step 4: Final Answer:
The isthmo-ampullary segment is ligated, matching option (B).
