What is Frozen Section?
Frozen section is a rapid biopsy done during surgery to diagnose an ovarian cyst, tumour, or mass in real time. In simple terms, it is a “LIVE biopsy” performed while the patient is still in the operation theatre.- Tissue is analysed immediately
- Report is available within 15–30 minutes
- Helps decide the next step of surgery instantly

What is a frozen section in ovarian surgery?
A frozen section is a rapid microscopic examination of the removed ovarian tissue, done while the patient is still under anaesthesia.
How long does a frozen section take?
The pathologist usually reports within twenty to forty minutes, so the operation continues while the answer is awaited.
How accurate is frozen section for an ovarian tumour?
Frozen section is highly reliable for telling benign from malignant. Borderline tumours are the harder group and need the final histopathology report.
Why does the frozen section matter?
It decides in the same sitting whether removing the mass is enough or whether full staging surgery should be completed straight away.

Does frozen section replace the final biopsy report?
No. Final histopathology follows in three to five days and is the report that confirms the diagnosis and the stage.
How Frozen Section Works
- Tumour is removed without rupture
- A small sample is sent fresh to the lab
- Tissue is frozen, sliced, and examined under microscope
- Pathologist gives an immediate diagnosis
Why Frozen Section is Critical in Ovarian Tumours
In most ovarian cases:
- Biopsy is NOT done before surgery
- Because it can cause tumour rupture and spillage
That’s where frozen section becomes essential
It acts as a safe “LIVE biopsy” during surgery
Treatment is not decided only before surgery How Treatment is Planned
Final decisions are made during surgery using:
- Resection without rupture
- Frozen section (LIVE biopsy)
This allows:
Right surgery to be performed in a single operation
Why Biopsy Should Be Avoided Before Surgery
In most ovarian masses, preoperative biopsy is NOT recommended
1. Risk of Tumour Rupture
- Needle biopsy can puncture the cyst/tumour
- Leads to spillage → cancer spread
2. Does Not Change Treatment Plan
- If biopsy shows cancer → surgery is still required
- If biopsy shows no cancer → not reliable (only small sample taken)
3. False Reassurance Risk
- A negative biopsy does NOT rule out cancer
Why Not Do Biopsy Before Surgery?
Risk of Biopsy Before Surgery
- Risk of tumour rupture → cancer spread
- May increase cancer stage
- May lead to unnecessary chemotherapy
Why Biopsy is Not Reliable
- A small biopsy sample is not always reliable
- Surgery is still required even if biopsy shows cancer
Therefore, diagnosis is best done during surgery using frozen section
How Frozen Section Changes Surgery (Real Impact)
Frozen section helps answer 3 critical questions immediately:
1. Is it benign / borderline / malignant?
2. What type of tumour is it?
3. How much surgery is needed?
Benign tumour
Limited surgery / ovary preservation
Borderline tumour
Staging with fertility consideration
Malignant tumour
Complete staging / cytoreductive surgery
One surgery. One decision. No delay.
Helps avoid second surgery
When is Frozen Section Used?
Frozen section is commonly used during ovarian tumour surgery to help surgeons make accurate decisions immediately during the operation.
Used in Most Ovarian Masses
Frozen section is used in most localized ovarian cysts, complex cysts, tumours, or masses
Important Principle
Since biopsy is avoided before surgery,
Frozen section becomes the safest and most effective way to diagnose during surgery
Highly Reliable
- Accuracy: ~90–97%
- Highly reliable for benign vs malignant tumours
Limitations
- Borderline tumours
- Very large masses
Final confirmation is always done by histopathology
Frozen Section vs Final Histopathology
Frozen Section
Timing: During surgery
Speed: 15–30 minutes
Purpose: Guide surgery
Detail: Preliminary
Final Histopathology
Timing: After surgery
Speed: Few days
Purpose: Confirm diagnosis
Detail: Detailed
What If Frozen Section is Not Available?
Surgery may be:
Incomplete (miss cancer)
Excessive (remove more than needed)
Or patient may need:
Second surgery
This increases:
Cost
Stress
Treatment delay

Ovarian mass resection with frozen section is a specialized surgical procedure performed to remove an ovarian mass, such as a tumor or cyst, from the ovary. During the surgery, a critical step involves sending a small sample of the removed mass for immediate frozen section analysis. This advanced technique involves rapidly freezing the tissue and examining it under a microscope while the surgery is still ongoing. It allows the medical team to immediately determine if the tumor is benign (non-cancerous) or malignant (cancerous), which guides real-time decisions about the extent of the surgery.
During the consultation, it was discovered that the patient had an ovarian cyst that required surgical removal. The laparoscopic procedure was performed just a week before the video was recorded. The patient describes the surgery as a seamless and mostly painless experience. She praises Dr. Swati Shah for her calm, composed nature and exceptional surgical expertise. The minimally invasive nature of the laparoscopy allowed for an incredibly fast recovery; within just one week, the patient’s stitches were removed, and she is already feeling fully recovered and doing well.

Exploratory Laparotomy And Complex Excision For A Suspicious Right Adnexal Mass
- The Challenge
- Managing A Suspicious Pelvic Mass
A 49-year-old female presented with severe lower abdominal pain persisting for fifteen days, alongside an alarming heterogenous solid-cystic right pelvic mass. Imaging strongly suggested a neoplastic etiology with pelvic lymphadenopathy, necessitating highly urgent surgical intervention to rule out an aggressive ovarian malignancy.
The Solution
⦿ Comprehensive Exploratory Laparotomy
Dr. Swati Shah performed an exploratory laparotomy, right adnexal mass excision, left oophorectomy, appendicectomy, bilateral pelvic lymph node dissection, and omental biopsy. The team navigated complex adhesions, carefully separating the appendix from the tumor. This exceptional surgical precision ensured complete tissue removal and maximized patient safety.
