Omentopexy involves surgically fixing the omentum in place. The omentum is a fatty structure formed from the peritoneum, the lining inside the abdominal cavity. It can adhere to the abdominal wall and accelerate the healing process. Omentopexy helps manage conditions like perforated peptic ulcer, catheter insertion in the peritoneal layer, and Buerger’s disease. You will need to fast for at least eight hours before the surgery. This surgery is performed using general anaesthesia to keep you relaxed and pain-free during the surgery. The procedure may differ based on the condition. Once you reach home, you will have to restrict a few activities and take proper care for fast recovery.

Doctors for Omentopexy

Omentopexy is a surgical procedure to fix the omentum by suturing it to the abdominal wall. The procedure is done for the management of multiple conditions like perforated peptic ulcer, fixation of a catheter (small, thin tube) in peritoneal dialysis, and Buerger’s disease. The omentum is a fat-rich structure formed from the inner layer of the peritoneum (lining of the abdomen). It possesses good healing properties and is present as a sheet that lies over the intestines.

Omentopexy is performed in the following conditions:

  • Peritoneal dialysis: Peritoneal dialysis is done to purify blood in case of kidney failure. Omentopexy is done prophylactically to prevent obstruction of the catheter by the omentum during dialysis.
  • Perforated duodenal ulcer: Duodenal ulcer is an open sore in the initial section of the small intestine. It can lead to a hole in the intestine called a perforation. Omentopexy can help by improving blood supply and promoting healing in this area. The symptoms of this condition are as follows:
  • Buerger’s disease: In this condition, the blood vessels of the hands and feet are blocked, mainly with a clot. This can lead to ulcer and pain in limbs. Omentopexy can help with healing of both ulcers and pain.

There is no specific contraindication to this surgery.

Before undergoing omentopexy, you will need the following preparation:

  • Your doctor will ask you to undergo a few diagnostic tests, including computed tomography (CT) scan or Doppler study (a type of sonography that involves measuring the amount of blood flow through blood vessels) to check the conditions mentioned earlier.
  • Tell your doctor about all the medicines that you take, including prescribed or non-prescribed medications, mineral, herbs, vitamins, and supplements, with your doctor.
  • You will need to fast for at least eight hours before this surgery.
  • Let your surgeon know if you have a fever, flu, etc., in the days leading to the operation. In such a case, your surgery may be postponed.
  • Also, let your doctor know if you have any allergies to foods, medicines, or surgical components like iodine, skin tapes, latex, adhesive, or skin cleansing solution. 
  • You will be asked to stop taking blood-thinners like aspirin, ibuprofen, warfarin, vitamin E, or clopidogrel for a minimum of two weeks before the surgery.
  • If you smoke, quitting this habit can help you recover fast after the surgery.
  • Arrange for a family member, friend, or a responsible adult to drive you home after your discharge from the hospital.
  • You will be asked to sign an approval or consent form to assure your willingness for the procedure.

This surgery is usually performed by laparoscopic method. This method has a low risk of infection and you will have a short hospital stay after the surgery.

Once you are admitted to the hospital, 

  • The medical staff will ask you to change into a hospital gown.
  • You will lie on an operating table in supine position i.e., sleeping on your back.
  • An intravenous (IV) line will be started in your arm to provide you medications and fluids during and after the procedure.
  • An anesthesiologist will then administer general anaesthesia (to keep you relaxed and pain-free during the surgery) to you.
  • You may also receive antibiotics (to reduce chances of infection) before the surgery.
  • A nasogastric tube will be inserted through your nose into your stomach to prevent spillage of contents of your stomach into your peritoneum. 
  • A urinary catheter will be placed into your bladder to drain out urine.
  • The medical team will constantly monitor your vital functions, including your blood pressure and heart rate throughout the surgery.

The following steps are performed to manage Buerger’s disease and perforated peptic ulcer:

  • The surgeon will insert three trocars (a tube with sharp edges) near your belly button to access the inside of your abdomen; the incision points of these trocars will form an equilateral triangle. 
  • He/she will explore your abdomen to locate the perforated area.
  • Once the area is located, the surgeon will stitch the omentum in the region onto the perforation using figure of eight stitches to cover the hole. 
  • Finally, the surgeon will place drains in the wound (to remove any accumulated fluids) and stitch your skin to close the incisions.

For peritoneal dialysis, the following steps are performed:

  • The surgeon will use three trocars to make cuts over your abdominal area. 
  • He/she will inflate your abdomen with gas for better visualisation of your internal organs.
  • The surgeon will check your abdomen for the presence of any adhesions (scar tissue bands that bind two tissues/organs that are not normally joined together).
  • He/she will bring your small intestine outside to be able to view your pelvic cavity.
  • Thereafter, the surgeon will use sutures to fix your sigmoid mesentery (tissue that attaches the last section of the bowel - sigmoid colon - to the wall of the pelvic cavity) and lateral peritoneum.
  • The surgeon will insert the peritoneal dialysis catheter into place and fix it with sutures.
  • Finally, he/she will stitch the incisions.

The surgeon will take about 140 to 180 minutes to complete this procedure. After the procedure, a nurse will give you painkillers through an IV. The urine catheter will be removed on the next day of your surgery. The nasogastric tube will be removed after three to five days. You will be kept on a clear fluid diet for the first few days. Later, as you recover, the doctor will permit you to start with your regular diet. Once your diet and bowel movement resume, you will be discharged from the hospital.

After the surgery for Buerger’s disease, you will be asked to avoid bending your legs for at least three to four days. For peritoneal dialysis, the peritoneal dialysis fluid will be passed through the tube for the initial three days. Your dialysis will be performed on the fourth day after the surgery. During this period, the doctor may perform a few radiology tests to locate the catheter inside your abdomen.

Once you are home, you will need to take the following care:

  • Medications: 
    • If the doctor has given any medicine, follow the prescription thoroughly.
    • You will be prescribed painkiller medicines to reduce your pain after the surgery.
  • Wound care:
    • Avoid applying any lotion or ointment on the operated site. 
    • You may be allowed to take a shower after two days of surgery. 
    • Avoid taking a bath in a bathtub or swimming until advised by the doctor. 
    • Wear loose-fitted clothes to prevent irritation of the surgical area.
  • Diet:
    • If you have undergone omentopexy for problems of the gastrointestinal tract, you will be asked to follow a liquid diet for two weeks and then gradually progress to solid foods.
  • Activities:
    • You must restrict driving while you are on pain medications. However, if there is no pain, you can resume driving one to two weeks after the surgery. 
    • You can take a walk for a few minutes every day to stay active after the surgery. 
    • Avoid lifting heavy objects. 
    • You may be allowed to climb stairs. However, do not stress yourself.
