GORD: Reflux Surgery
What is GORD?
Gastric reflux, also called gastro-oesophageal reflux disease (GORD), is a condition where the stomach’s contents (food or liquid) rise up from the stomach into the oesophagus, a tube that carries food from the mouth to the stomach. Food mixed with the stomach’s digestive acids can irritate and damage the oesophagus.
Causes of GORD
Normally, the stomach’s contents are retained in the stomach with the help of the lower oesophageal sphincter (LES), a muscle that contracts and relaxes to maintain the one-way movement of food. However, gastric reflux occurs when the LES weakens. The exact cause of this is not known, however, certain factors including obesity, smoking, pregnancy and possibly alcohol, may contribute to GORD. Common foods such as spicy foods, onions, chocolates, caffeine- containing drinks, mint flavourings, tomato-based foods, citrus fruits and certain medications can worsen gastric reflux.
Symptoms of GORD
Heartburn is usually the main symptom of GORD, characterised by a burning-type pain in the lower part of the mid-chest, behind the breast bone. Other symptoms include a bitter or sour taste in the mouth, trouble swallowing, nausea, dry cough or wheezing, regurgitation of food (bringing food back up into the mouth), hoarseness or change in voice and chest pain.
Diagnosis of GORD
Your doctor may order some of the following tests to diagnose gastric reflux:
- Endoscopy: allows the doctor to examine the inside of your oesophagus, stomach and portions of the intestine with an instrument called an endoscope, a thin flexible lighted tube
- Barium X-rays: involves swallowing a barium preparation, which can be detected through X-rays
- 24-hour pH monitoring: involves inserting a tube through your nose into the oesophagus, and positioning it above the LES. The tip of the tube contains a sensor which can measure the pH of the acid content refluxed into the oesophagus. The tube will be left in place for 24 hours.
- pH capsule:allows measuring acid exposure in the oesophagus. A small wireless capsule is introduced into the oesophagus by a tube through the nose or mouth. The tube is removed after the capsule is attached to the lining of the oesophagus. The pH sensor transmits signals to a computer which collects the data about the acid exposure over the next 24 hours. The capsule eventually falls off the oesophagus lining and is safely passed in the stool.
- Impedance study:requires two probes; one is placed in the stomach and the other just above the stomach. The dual sensor helps to detect both acidic and alkaline reflux.
Treatments for GORD
Treatment aims at reducing reflux, relieving symptoms and preventing damage to the oesophagus. Some of the treatment options include:
- Antacids: over-the-counter medicines that provide temporary relief to heartburn and indigestion by neutralizing acid in the stomach
- Other medications: reduce the production of acid in the stomach
- Endoluminal gastroplication or endoscopic fundoplication technique: minimally-invasive method that requires the use of an endoscope with a sewing device attached to the end, known as an EndoCinch device. This instrument places stitches in the stomach below the LES to create a plate which helps reduce the pressure against the LES and strengthen the muscle.
- Nissen’s fundoplication:is a surgical procedure in which the upper part of the stomach is wrapped around the end of your oesophagus and oesophageal sphincter, where it is sutured into place. This surgery strengthens the sphincter and helps prevent stomach acid and food from flowing back into the oesophagus.
Surgical Treatment for GORD
If conservative treatment options fail to resolve your GORD, your doctor may recommend a surgical procedure called Nissen Fundoplication. Nissen Fundoplication surgery reinforces the lower oesophageal sphincter’s ability to close and helps to prevent gastro-oesophageal reflux from occurring. This surgery can be performed laparoscopically through tiny incisions in the abdomen or through an open approach, which requires a large abdominal incision.
Nissen Fundoplication is performed on an outpatient basis under general anaesthesia. Steps involved in Nissen Fundoplication procedure include:
- Your surgeon makes a small incision in the upper abdomen and inserts a tube called a trocar through which the laparoscope is introduced into the abdomen. A laparoscope is a long, narrow telescope with a light source and video camera at the end. The scope is passed through a tiny incision into the abdomen where images from the camera are projected onto a large monitor for the surgeon to view. Laparoscopes have channels inside the scope enabling your surgeon to pass gas in and out to expand the viewing area or to insert tiny surgical instruments for treatment purposes.
- Additional small incisions may be made for other surgical instruments.
- With the images from the laparoscope as a guide, your surgeon wraps the upper part of the stomach, the fundus, around the lower oesophagus to create a valve, suturing it in place.
- The hole in the diaphragm through which the oesophagus passes is then tightened with sutures.
- The laparoscope and other instruments are removed and the gas released.
- The tiny incisions are closed and covered with small bandages.
After the surgery, you should keep the area clean and dry, and not shower or bathe during this time. The incisions usually heal in about 5 days. You may feel soreness around the incision areas. If the abdomen was distended with gas, you may experience discomfort in the abdomen, chest or shoulder area for a couple of days while the excess gas is being absorbed. Contact your doctor immediately if you have a fever, chills, increased pain, bleeding or fluid leakage from the incisions, chest pain, and shortness of breath, leg pain or dizziness.
Laparoscopy is much less traumatic to the muscles and soft tissues than the traditional method of surgically opening the abdomen with long incisions (open techniques). It is also associated with a shorter hospital stay, less post-operative pain and faster recovery.
Postop Stages of Recovery and Care Plan
Your surgeon may give you a prescription pain medicine or recommend non-steroidal anti-inflammatory drugs (NSAIDs) for the first few days to keep you comfortable. Your surgeon may instruct you about your diet and activity restrictions. Care should be taken with your wound. You are advised not to lift heavy objects for 8 to 12 weeks.
