Irving operation

Irving operation is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Irving operation rather than just read about it. In short: Irving Operation is a gynaecological operative technique for permanent sterilization in women. It was proposed to reduce the failure rate of Pomeroy procedure for female sterilization.

Key takeaways

Irving operation belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Irving operation to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Irving operation from memory before moving on to harder problems.

Reference excerpt

Irving Operation is a gynaecological operative technique for permanent sterilization in women. It was proposed to reduce the failure rate of Pomeroy procedure for female sterilization. In Irving operation, the proximal part of fallopian tube is buried back into the myometrium, thereby obstructing its lumen.

History The Irving operation was proposed by Dr. Irving in 1924.

Operation technique A transverse incision is made on the abdomen and fallopian tube is identified. While holding the fallopian tube with an Allis clamp, a hemostat is used to open the mesosalpinx. Using absorbable sutures, proximal portion of fallopian tube is tied, and a segment of fallopian tube is removed. The proximal part of the fallopian tube is pulled into the defect. The distal portions of the Fallopian tube are ligated and left in place. The abdomen is closed in layers.

Reversal Irving operation can be reversed with tubal reversal microsurgery. Pregnancy rate after tubal reversal in Irving operation is around 60 percent.

Worked examples

Example 1 — a first encounter with Irving operation

Start with the simplest possible case. Write down what Irving operation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Irving operation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Irving operation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Irving operation

In research: Irving operation appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Irving operation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Irving operation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Gynaecology stubs, Gynecological surgery, Sterilization (medicine), so understanding it makes those chapters shorter.
In everyday life: Look for Irving operation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Irving operation in simple terms?

Irving Operation is a gynaecological operative technique for permanent sterilization in women. It was proposed to reduce the failure rate of Pomeroy procedure for female sterilization.

Why does Irving operation matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Irving operation?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
