Overview of Omentectomy Surgery
An omentectomy is a surgical procedure to remove all or part of the omentum, the fatty tissue layer covering abdominal organs. It is most commonly performed as part of cancer treatment, particularly for ovarian, gastric, and colorectal cancers, or to address severe abdominal infections. At Artemis Hospitals, Gurugram, our experienced surgical oncology team performs this procedure using the latest minimally invasive and robotic-assisted techniques.

What is an Omentectomy?
The omentum is a large, apron-like fold of fatty tissue that hangs from the stomach and covers the intestines. It plays a role in immune defence and fat storage within the abdominal cavity. An omentectomy is the surgical removal of this tissue, either partially or completely, depending on the clinical indication.
Because cancer cells frequently spread to the omentum — a process called omental metastasis — removing it is often a critical step in controlling the spread of disease. The surgery may be performed alone or as part of a larger procedure such as cytoreductive (debulking) surgery.
Why is Omentectomy Performed?
Omentectomy is performed for several important medical reasons. The most common indication is the removal of cancerous or pre-cancerous tissue that has seeded or spread to the omentum. In other cases, it may be necessary to manage severe abdominal infections, adhesions, or benign tumours. The goals of the procedure include eliminating active disease, reducing tumour burden, preventing further spread, and improving the effectiveness of chemotherapy or radiation therapy that follows surgery.
Types of Omentectomy
Partial Omentectomy
Only a section of the omentum is removed. This is used when the disease is localised to one area, allowing the surgeon to preserve healthy omental tissue while excising the affected portion.
Total Omentectomy
The entire omentum is removed. This approach is standard in advanced ovarian cancer or when widespread omental involvement is detected. Patients tolerate total removal well, as the omentum is not essential for survival.
Omentectomy with Cytoreductive (Debulking) Surgery
In this combined approach, the omentectomy is performed alongside the removal of other visible tumour deposits throughout the abdominal cavity. This is common in peritoneal carcinomatosis and advanced ovarian cancer, where the aim is to reduce overall tumour volume to as low as possible.
Conditions Treated with Omentectomy
Omentectomy is used to treat a range of serious abdominal and oncological conditions, including:
- Ovarian cancer – The most common indication; omental spread ("omental cake") is frequently seen in advanced stages.
- Gastric (stomach) cancer – Omental involvement may occur via direct extension or lymphatic spread.
- Colorectal cancer – Omentectomy is performed when colorectal tumours have spread to the omental tissue.
- Peritoneal carcinomatosis – A condition where cancer has spread widely across the peritoneal lining, often treated with cytoreduction plus omentectomy.
- Abdominal infections or tumours – In rare cases, the omentum becomes involved in severe infections such as omental infarction, or develops benign primary tumours requiring excision.

Surgical Approaches for Omentectomy
Open Omentectomy Surgery
This traditional approach involves a large abdominal incision. It provides the surgeon with direct access and wide visibility, making it suitable for complex or advanced cases. Recovery time is longer compared to minimally invasive options.
Laparoscopic Omentectomy
Using small incisions and a camera-guided instrument system, laparoscopic omentectomy offers shorter hospital stays, reduced post-operative pain, and faster recovery. It is the preferred approach for early-stage or less complex cases where omental involvement is limited.
Robotic-Assisted Omentectomy
Robotic surgery combines the precision of technology with the surgeon's expertise. The robotic arms offer enhanced dexterity and three-dimensional visualisation inside the abdominal cavity. Artemis Hospitals, Gurugram is equipped with advanced robotic surgical systems, enabling surgeons to perform omentectomies with greater precision and minimal trauma to surrounding tissue.
When Should I Consult a Doctor?
You should seek a medical consultation promptly if you experience any of the following symptoms, which may indicate abdominal or omental pathology:
- Persistent or worsening abdominal pain or bloating
- Unexplained weight loss combined with abdominal discomfort
- A palpable mass or lump in the abdomen
- Ascites (fluid accumulation in the abdomen)
- Recommended follow-up after initial cancer staging that includes imaging of the omentum
Early consultation ensures timely staging, surgical planning, and the best possible outcomes.
How Can I Prepare For Omentectomy Surgery?
Days Before Surgery
Our surgical team at Artemis Hospitals will conduct a thorough pre-operative assessment, including blood tests, imaging (CT scan or MRI), and an anaesthesia review. You may be asked to stop certain medications such as blood thinners or anti-inflammatory drugs. Bowel preparation may be prescribed to clear the intestine before surgery.
One Day Before Surgery
You will typically be asked to fast from midnight. Confirm your arrival time with the hospital and ensure a family member or caregiver is available to accompany you. Complete any outstanding consent forms and bring all previous medical reports and imaging.
On the Day of Surgery
Arrive at the hospital at the scheduled time. The surgical and anaesthesia team will brief you again on the procedure. You will be given a hospital gown, and an intravenous (IV) line will be placed. Your team will answer any last-minute questions before you are taken to the operating theatre.
How is Omentectomy Surgery Performed?
Type of Anaesthesia Used
Omentectomy is performed under general anaesthesia, meaning you will be completely asleep and pain-free throughout the procedure.
Step-by-Step Surgical Process
Once anaesthesia takes effect, the surgeon makes either a single large incision (open surgery) or several small incisions (laparoscopic or robotic approach). The abdominal cavity is examined, and the extent of omental involvement is assessed. The surgeon carefully separates the omentum from the stomach and colon using surgical instruments, cauterisation, and sutures as needed. The excised omental tissue is sent to pathology for analysis. If combined with debulking surgery, additional tumour deposits are addressed at this stage. The incisions are then closed with sutures or staples.
Average Duration of the Procedure
An isolated omentectomy typically takes between one and two hours. When performed as part of cytoreductive surgery, the total operative time may extend to three to four hours or longer, depending on the extent of disease.
What to Expect After Omentectomy Surgery?
Immediately After Surgery
You will wake up in the recovery room with monitoring equipment in place. Mild pain, nausea, and grogginess are expected in the initial hours. Pain medication will be administered through the IV line.
First Few Days
Hospital stay ranges from two to five days. You will begin with clear liquids and progress to soft foods. The nursing team will help you with early mobilisation, typically starting with short walks the day after surgery. Drains may be placed during surgery and removed before discharge.
Long-Term Prognosis
Long-term outcomes depend on the underlying condition, the completeness of surgical resection, and subsequent treatments such as chemotherapy. Patients who undergo successful cytoreduction followed by adjuvant chemotherapy generally have significantly improved survival outcomes.
Normal vs. When to Call a Doctor
It is normal to experience mild fatigue, incision site tenderness, and reduced appetite for several weeks. However, you should contact your doctor immediately if you notice fever above 38°C, increasing redness, swelling or discharge at the wound site, severe abdominal pain, vomiting, or inability to pass stools or gas.
What are the Advantages of Omentectomy Surgery?
- Removes or reduces cancerous tissue that may otherwise spread or resist chemotherapy
- Improves the effectiveness of post-operative systemic treatments
- Can significantly extend survival in patients with advanced abdominal cancers
- Minimally invasive and robotic approaches reduce recovery time and post-operative complications
- Pathology from omental tissue provides critical diagnostic information for staging and treatment planning
- Improves quality of life by reducing symptoms such as abdominal bloating and discomfort caused by omental disease
Risks and Complications of Omentectomy
Common Surgical Risks
As with any major surgery, omentectomy carries potential risks including bleeding, infection at the incision site, anaesthetic reactions, blood clots (deep vein thrombosis or pulmonary embolism), injury to surrounding structures (bowel, bladder, or blood vessels), and adhesion formation. When combined with cytoreductive surgery, there is also a risk of prolonged recovery and a higher likelihood of needing intensive post-operative care.

What are the Recovery Tips After Omentectomy Surgery?
Pain Management and Wound Care
Take prescribed pain medications as directed and do not stop them abruptly. Keep the wound clean and dry. Attend all follow-up appointments for wound inspection. Report any signs of infection immediately. Avoid lifting heavy objects or strenuous physical activity for at least four to six weeks following open surgery.
Diet, Movement, and Activity Guidelines
Begin with a bland, easily digestible diet and gradually reintroduce regular foods as tolerated. Stay well-hydrated. Short, gentle walks are encouraged from day one post-discharge and should be increased progressively. Avoid driving until cleared by your surgeon. Return to normal activities is usually possible within four to six weeks for open surgery and two to three weeks for laparoscopic surgery.
