Gastroparesis – The Good and Bad – Part 3
Fortunately, there are prescription medications to treat gastroparesis. Often a combination of medications are used to determine the most effective treatment. The list of medications is short and includes:
#1. Metoclopramide (Reglan). This medication stimulates stomach muscle contractions to help with gastric emptying. Metoclopramide also helps reduce nausea and vomiting. The medication is taken 20 to 30 minutes before meals and at bedtime. Possible side effects of metoclopramide include fatigue, sleepiness, and depression. Currently, this is the only medication approved by the FDA for treatment of gastroparesis. The FDA has placed a black box warning on this medication because of rare reports of it causing an irreversible neurologic side effect called tardive dyskinesia, which is a disorder that affects movement.
#2. Erythromycin. This antibiotic, prescribed at low doses, may improve gastric emptying. Like metoclopramide, erythromycin works by increasing the contractions that move food through the stomach. Possible side effects of erythromycin include nausea, vomiting, and abdominal cramps.
#3. Other medications. Other medications may be used to treat symptoms and problems related to gastroparesis. For example, medications known as antiemetics are used to help control nausea and vomiting.
#4. This is not a medication and care should be used if you allow this. Botulinum toxin is a nerve-blocking agent also known as Botox. After passing an endoscope into the stomach, a doctor injects the Botox into the pylorus, the opening from the stomach into the duodenum. Botox is supposed to help keep the pylorus open for longer periods of time and improve symptoms of gastroparesis. Although some initial research trials showed modest improvement in gastroparesis symptoms and the rate of gastric emptying following the injections, other studies have failed to show the same degree of effectiveness of the Botox injections.
There are procedures that are also used and have varying degrees of success. The following are the ones used currently:
#1. Gastric Electrical Stimulation This treatment alternative may be effective for some people whose nausea and vomiting do not improve with dietary changes or medications. A gastric neurostimulator is a surgically implanted battery-operated device that sends mild electrical pulses to the stomach muscles to help control nausea and vomiting. The procedure may be performed at a hospital or outpatient center by a gastroenterologist. General anesthesia may be required. The gastroenterologist makes several tiny incisions in the abdomen and inserts a laparoscope—a thin tube with a tiny video camera attached. The camera sends a magnified image from inside the stomach to a video monitor, giving the gastroenterologist a close-up view of the tissues. Once implanted, the settings on the battery-operated device can be adjusted to determine the settings that best control symptoms.
#2. Jejunostomy If medications and dietary changes don’t work, and the person is losing weight or requires frequent hospitalization for dehydration, a health care provider may recommend surgically placing a feeding tube through the abdominal wall directly into a part of the small intestine called the jejunum. The surgical procedure is known as a jejunostomy. The procedure is performed by a surgeon at a hospital or outpatient center. Anesthesia is needed. The feeding tube bypasses the stomach and delivers a special liquid food with nutrients directly into the jejunum. The jejunostomy is used only when gastroparesis is extremely severe.
#3. Parenteral Nutrition When gastroparesis is so severe that dietary measures and other treatments are not helping, a health care provider may recommend parenteral nutrition—an IV liquid food mixture supplied through a special tube in the chest. The procedure is performed by a surgeon at a hospital or outpatient center; anesthesia is needed. The surgeon inserts a thin, flexible tube called a catheter into a chest vein, with the catheter opening outside the skin. A bag containing liquid nutrients is attached to the catheter, and the nutrients are transported through the catheter into the chest vein and into the bloodstream. This approach is a less preferable alternative to a jejunostomy and is usually a temporary treatment to get through a difficult period of gastroparesis.
My friend and member of our support group, Allen, says that one of his friends had the last procedure and had to remain in the hospital to fight a resulting infection and does not recommend the last procedure above.
