Amilorrhoea : Causes, Symptoms, Diagnosis & Treatment

Last Updated: 15/06/2022

Amylorrhea is the appearance in the stool of a large number of starch grains, which indicates a violation of the digestion of carbohydrates. The symptom occurs with enzyme deficiency - chronic pancreatitis, enteritis, pancreatic tumors. Amylorrhea is observed with increased peristalsis, which happens with IBS, intestinal infections, hyperacid gastritis. The diagnostic plan involves functional probe and probeless methods, coprogram, instrumental imaging of the pancreas. Treatment includes diet therapy, pancreatic enzyme preparations, antacids, and probiotics.

Causes of Amilorrhoea

irritable bowel syndrome

The appearance of a symptom is possible with IBS with a predominance of diarrhea. Amylorrhea is caused by increased intestinal motility, as a result of which digestive enzymes do not have time to act on carbohydrates. It is manifested by liquid stools of yellow or light brown color with an unpleasant pungent odor. Before defecation, spastic pain in the abdomen increases, after emptying the intestines, it decreases or completely disappears.

Intestinal infections

Amylorrhea in case of poisoning is caused not only by the activation of peristalsis, but also by the direct toxic effect of pathogenic microorganisms on the wall of the small intestine. The symptom is more typical for the onset of the disease, when there is a sufficient amount of partially digested food in the stomach and intestines. There is diarrhea, the multiplicity of which depends on the severity of the intestinal infection. Fecal masses are liquid, have a bright yellow, orange or greenish tint.

Hyperacid gastritis

The appearance of amylorrhea is due to two mechanisms: the inactivation of salivary amylase in the acidic environment of the stomach and the accelerated movement of chyme due to the irritating effect of acid on the small intestine. Disorders of the stool are associated with errors in the diet - the use of large amounts of complex carbohydrates. There is one or two diarrhea with the release of liquid fetid feces. Amylorrhea is accompanied by abdominal cramps, epigastric pain.

Chronic pancreatitis

With inflammation of the pancreas, signs of amylorrhea are relatively rare, which is explained by the high enzymatic activity of intestinal amylase. The condition is more often observed with advanced forms of the disease. Amylorrhea occurs when the diet consists mainly of carbohydrate foods. A person is worried about severe flatulence and pain in the epigastric region. Then there is an unformed, fetid stool, in which there may be particles of undigested food.

If the diet is followed, amylorrhea disappears. Chronic pancreatitis is characterized by a sequence of changes in the composition of feces. First, steatorrhea occurs, as evidenced by grayish soft feces with a greasy sheen. Creatorrhoea joins later, amylorrhea develops in the later stages of the disease. The symptom is also typical for a complication of pancreatitis - pancreatic fibrosis.

Enzyme deficiency of the pancreas

Violation of the exocrine function of the organ is accompanied by a decrease in the production and release of pancreatic amylase into the small intestine. In the initial stages, the condition is compensated by intestinal enzymes, but at the advanced stages of the disease, amylorrhea may begin. It has typical clinical manifestations specific to the chronic form of pancreatitis. The main causes of exocrine pancreatic insufficiency:

  • Congenital pathologies : genetic enzyme deficiency, pancreatic agenesis or hypoplasia, Shwachman-Diamond syndrome.
  • Volumetric formations : congestive, tumor and parasitic cysts, pancreatic cancer.
  • Postoperative complications : during operations on the stomach, small intestine, pancreatic gland.

 

Chronic enteritis

With an inflammatory lesion of the wall of the small intestine, the secretion of enzymes is disrupted, the processes of cavitary and parietal digestion are inhibited. Undigested carbohydrates in the form of starch move into the large intestine, increase peristalsis and increase the water content of feces. Therefore, with amylorrhea, repeated diarrhea occurs. The stool has a liquid consistency or is allocated with separate soft lumps.

Complications of pharmacotherapy

Amylorrhea is provoked by an overdose of laxatives that affect intestinal motility. As a result, the person develops diarrhea. Food quickly passes through the digestive tract and does not have time to completely break down. Fecal masses are plentiful, liquid, have a sharp unpleasant odor. Amylorrhea is combined with spasms and discomfort in the abdomen, flatulence. After 12-24 hours, the effect of the drugs ends, the condition returns to normal.

Diagnostics

During an external examination, a gastroenterologist draws attention to the lack of body weight in a patient with amylorrhea. Often, dryness and peeling of the skin, brittle nails, seizures are detected, which indicates a vitamin deficiency. It turns out the frequency and nature of the stool, especially nutrition, against which the symptoms appeared. To determine the causes of amylorrhea, laboratory and instrumental methods are used:

  • Stool analyses. In the coprogram, an increased content of starch grains, neutral fats and undigested muscle fibers is found. To clarify pancreatic functions, the level of fecal elastase is measured. With a possible intestinal infection, as a cause of amylorrhea, stool culture is indicated.
  • functional tests. To assess enzymatic activity, probe and probeless methods are performed. The pathology of the organ, manifested by amylorrhea, is evidenced by an insufficient increase in the volume of secretion and the level of bicarbonates after drug stimulation. As a screening method, a blood test for amylase, lipase is performed.
  • Instrumental visualization. To study the structure, contours and echogenicity of the organ, an ultrasound of the pancreas is performed. For a more detailed study of the parenchyma, a patient with amylorrhea needs an MRI. Selective angiography is informative to exclude malignant neoplasms. The state of the pancreatic ducts is examined using ERCP.
  • Fibrogastroduodenoscopy. The technique is recommended for suspected hyperacid gastritis, provoking amylorrhea. With EFGDS, specific inflammatory changes in the gastric wall, erosion are noticeable, and ulcerative defects are sometimes found. To change the level of secretion of hydrochloric acid, intragastric pH-metry is performed.
  • Biopsy. An invasive study with sampling of pancreatic tissue is necessary to assess the degree of fibrosis and destruction of the parenchyma, to identify damage to the insular apparatus in those suffering from amylorrhea. The biopsy technique is very important for understanding the prognosis of the disease, the choice of treatment tactics.

Treatment

Help before diagnosis

Regardless of the cause of amylorrhea, the first step in eliminating symptoms is diet therapy. A balanced diet in terms of protein and energy content with a high content of vitamins is recommended. Preference is given to easily digestible food, which does not cause functional overload of the digestive organs, reduces or completely eliminates amylorrhea. A prerequisite is quitting smoking, since nicotine reduces the synthesis of bicarbonates and contributes to the acidification of the small intestine.

Conservative therapy

Enzyme preparations are effective in combating amylorrhea. They are dosed according to the amount of lipase, since its secretion is disturbed in the first place. They select effective drugs in microgranular form, which are resistant to the action of gastric juice and provide a rapid release of enzymes. With amylorrhea, in addition to replacement therapy, after confirming the diagnosis, a number of drugs are prescribed:

  • Probiotics . The funds are aimed at normalizing the intestinal biocenosis, reducing fermentation processes. They eliminate the effects of diarrhea, reduce flatulence, improve digestion, thus reducing amylorrhea. To enhance the effect, probiotics are combined with prebiotics.
  • Antisecretory drugs . Used for gastritis with high acidity and amylorrhea. Proton pump inhibitors, H2-histamine blockers are used. Medicines quickly normalize the secretion of hydrochloric acid, slow down gastric and intestinal motility.
  • Antacids . Medicines are recommended for the treatment of diarrhea associated with amylorrhea. They have an astringent effect, neutralize the irritating effect of hydrochloric acid on the intestinal wall. With a stool frequency of about 10 or more times a day, special antidiarrheal drugs are indicated.
  • Insulin . Replacement therapy is appropriate in case of concomitant violation of the endocrine function of the pancreas. The dosage and frequency of administration are selected individually, taking into account the level of glucose in the blood, the indicators of the glucose tolerance test, the severity of amylorrhea.
  • Vitamins . Injectable vitamin drugs are administered with advanced form of pancreatitis with malabsorption of all nutrients. To correct the electrolyte composition of the blood in amylorrhea, preparations of magnesium, copper, zinc are intended.

Surgery

With severe atrophy of the organ, surgical interventions are carried out in specialized centers. Patients are transplanted with islets of Langerhans followed by removal of the gland. Such treatment requires lifelong enzyme replacement therapy. In case of malignant neoplasms, a radical operation is performed - pancreatoduodenal resection or resection of the pancreas with preservation of the pyloric zone and duodenum 12.
