Ovarian Cancer Surgery: Types, What to Expect, and Why Your Surgeon Matters

Ovarian cancer surgery is, for many patients, the first and most important step in treatment. 

From the type of cancer and how far it has spread, to whether you want to preserve your fertility, to the specific surgeon and their team, the decisions made around surgery are among the most consequential of your entire care journey.

This guide breaks down what you need to know: why surgery is so central, what the different types of surgery for ovarian cancer involve, how to prepare, and what recovery actually looks like.

Why Surgery Comes First

Surgery serves several critical purposes. It may remove as much cancer as possible, but that’s not always the first goal. 

Sometimes, surgery begins as an exploratory laparotomy or laparoscopy to confirm the diagnosis and assess how far the disease has spread. That assessment helps determine ovarian cancer staging, which shapes every treatment decision that follows.

In some cases, when tumor burden is extensive, a surgeon may determine during the operation that a full debulking isn’t safely achievable. The team will pivot to a biopsy for diagnosis, then recommend neoadjuvant chemotherapy first to shrink the tumor before attempting surgery again. 

Surgeons will only proceed with debulking when they believe they have a realistic chance of achieving an optimal result. So while surgery is almost always a central part of treatment, the sequence and scope depend entirely on what’s found — and what’s possible.

For women with early-stage disease, surgery may be the only treatment required. For those with advanced ovarian cancer, it typically opens the door to the rest of the treatment plan.

One of the most important things to understand going in: the goal is almost always to leave no visible tumor behind. The less cancer that remains after surgery, the more effectively follow-up chemotherapy can work on any microscopic disease that’s left.

How Ovarian Cancer Surgery Is Performed

There are two main surgical approaches your team may use.

Laparotomy is open surgery. The surgeon makes a larger incision in the abdomen to directly access the pelvis and abdominal cavity. It’s the standard approach for advanced disease, where extensive removal of tumor is the priority.

Laparoscopy (keyhole surgery) uses smaller incisions and a tiny camera called a laparoscope. The surgeon guides instruments through those incisions while viewing a monitor. 

It’s less invasive, often means a shorter hospital stay, and is typically used for early-stage cancers or diagnostic procedures. Some specialized centers also perform robotic-assisted laparoscopy, in which a surgeon uses precise controls to operate robotic arms, which studies suggest leads to less postoperative pain and faster recovery when performed by an experienced team.

Your surgical team will recommend the right approach based on stage, overall health, and surgical goals.

Types of Ovarian Cancer Surgery

The type of surgery recommended depends on the stage of the cancer, how far it has spread, and whether fertility preservation is a priority. In many cases, more than one procedure is performed during the same operation.

Salpingo-Oophorectomy

A salpingo-oophorectomy removes an ovary and its corresponding fallopian tube. It can be performed on one side (unilateral) or both sides (bilateral), depending on where the cancer is.

For very early-stage cancers, particularly low-grade tumors or borderline ovarian tumors, a unilateral approach may be possible, preserving the other ovary and the uterus. This is fertility-sparing surgery, meaning natural pregnancy may still be an option afterward.

If you want to explore fertility preservation, raise it with your oncologist before surgery. There are options, and the timing matters.

Total Abdominal Hysterectomy with Bilateral Salpingo-Oophorectomy (TAH-BSO)

Most patients will need a total abdominal hysterectomy combined with removal of both ovaries and fallopian tubes, referred to as a TAH-BSO. This removes the uterus, cervix, both ovaries, and both fallopian tubes in one procedure.

It’s the most common surgical approach for ovarian cancer because it removes the primary sites where cancer originates and commonly spreads, while giving the surgeon a clear view of the entire pelvic cavity.

One significant consequence: if you haven’t already gone through menopause, removing both ovaries will trigger it immediately. This is called surgery-induced menopause, and it comes with its own set of symptoms — hot flashes, bone density changes, and more — that are important to understand and plan for before your procedure.

Omentectomy

The omentum is a large fold of fatty tissue that drapes over the abdominal organs. It’s also one of the first distant places (non-reproductive organs) ovarian cancer tends to spread.

An omentectomy, the removal of all or part of the omentum, is almost always included in ovarian cancer surgery. It serves both to remove potential disease and to examine the tissue for cancer cells that aren’t visible to the naked eye. It’s considered a routine part of surgical staging.

Lymph Node Dissection

Lymph nodes are small glands throughout the body that help filter fluid and support immune function. They’re also a pathway through which ovarian cancer can spread.

During surgery, the surgeon may remove lymph nodes from the pelvis and around the abdominal aorta to check whether cancer has reached them. This procedure, called a lymphadenectomy, is a key part of accurate staging and directly influences treatment decisions that follow.

Debulking Surgery (Cytoreductive Surgery)

Cytoreductive surgery — commonly called debulking — is the removal of as much visible tumor as possible. It’s technically the goal of ovarian cancer surgery at any stage, though the term “debulking” is most commonly used in the context of advanced disease, where there is significant tumor burden spread throughout the pelvis and abdomen.

The result matters enormously. When surgeons achieve complete cytoreduction — meaning no visible tumor remains — outcomes improve significantly. Optimal cytoreduction, defined as residual disease less than 1 cm, is also associated with improved outcomes. Suboptimal cytoreduction, where more than 1 cm of tumor remains, is associated with poorer prognosis. That measurement shapes the post-surgical treatment plan.

In advanced cases, debulking may require removing portions of the bowel, the diaphragm, the spleen, the appendix, or other abdominal organs: whatever is necessary to get as close to a clean result as possible. 

It’s extensive surgery, and recovery is real. For a comprehensive look at what to expect, our guide on ovarian cancer post-surgery recovery covers the process step by step.

Sometimes debulking is performed after an initial round of chemotherapy has been used to shrink the tumor first. This is called interval cytoreductive surgery, and it’s used when primary surgery isn’t the safest or most effective starting point.

For patients with low-grade serous ovarian cancer (LGSOC) or borderline tumors, the surgical approach may differ from standard high-grade protocols, as these cancers behave differently and often affect younger women.

HIPEC (Hyperthermic Intraperitoneal Chemotherapy)

HIPEC, or hyperthermic intraperitoneal chemotherapy, is a specialized treatment that pairs surgery with a direct, targeted delivery of heated chemotherapy to the abdominal cavity — all during the same operation. Not every hospital offers it, but it’s available at major cancer centers.

Here’s how it works: once the surgeon has removed all visible tumor, small tubes (drains) are placed in the abdomen and connected to a HIPEC machine. Heated chemotherapy is then circulated through the abdominal cavity for approximately 60 to 90 minutes, targeting any microscopic cancer cells that may remain, before being drained out.

Because the chemotherapy is delivered directly to the site rather than through the bloodstream, higher concentrations can be used while minimizing full-body side effects. 

It’s typically considered for patients with advanced disease undergoing interval cytoreductive surgery. And it’s another reason why choosing a specialized center matters so much for surgery for ovarian cancer.

Bowel Resection and Extended Procedures

When cancer has spread to the bowel, the affected section may need to be removed. In most cases, surgeons can rejoin the healthy ends of the bowel, and it continues to function normally.

When that isn’t possible, a colostomy may be created: an opening in the abdomen through which waste passes into an external pouch. This can be temporary, with a possible follow-up procedure to reverse it once healing is complete.

Other extended procedures may include partial removal of the diaphragm, spleen, or liver, depending on how far the disease has spread. These decisions are made by the surgical team based on the full picture of the cancer at the time of surgery.

Does It Matter Who Performs Your Surgery?

Absolutely. And the research on this is consistent.

According to studies, surgery for ovarian cancer performed by a high-volume surgeon is associated with a 69% reduction in the risk of in-hospital death. Another study found that surgery by a gynecologic oncologist resulted in a 5- to 8-month median survival benefit for patients with advanced stage disease. 

This isn’t a small difference. It’s the difference that surgery by a gynecologic oncologist makes. If you’ve received a diagnosis or suspect ovarian cancer, getting that specialist involved from the start is not optional. It’s essential.

What to Expect After Ovarian Cancer Surgery

Hospital stays range from one to seven days depending on the scope of the procedure. More extensive surgeries require more in-hospital recovery time. Most patients are advised to avoid heavy lifting, vigorous exercise, and vaginal sex for around six weeks, or until their care team gives clearance.

Pain management is handled throughout. Your team will also monitor for complications such as infection, blood clots, or reactions to anesthesia.

Beyond the physical — surgery can trigger surgery-induced menopause suddenly, impact fertility, change body image, and bring a wave of emotions that are just as real as any physical symptom. These deserve equal attention.

Ovarian cancer support groups can be invaluable during this phase, especially for patients navigating menopause, fertility concerns, or the emotional weight of a major diagnosis. 

Final Thoughts on the Urgency of Ovarian Cancer Surgery

Ovarian cancer can spread  fast. Surgery is critical — and who performs it, and where, shapes outcomes in ways that matter deeply. If you or someone you love is facing this diagnosis, act quickly and advocate loudly for specialist care.

Because the more we understand about how surgery works — and the more we demand the right care from the right specialists — the better the outcomes become. For every woman facing this disease, that knowledge is power.
