Abdominal vibrating sound when fasting

Introduction The sound of water in the abdomen on the abdomen is a clinical feature of gastric retention. Gastric retention or delayed gastric emptying refers to the accumulation of gastric contents without timely emptying. Any food that has been ingested 4 to 6 hours before vomiting, or more than 8 hours on an empty stomach, and a residual amount of >200 ml in the stomach, indicates that there is gastric retention. The disease is divided into two types: organic and functional. The former includes pyloric obstruction caused by peptic ulcer, and pyloric obstruction caused by primary or secondary cancer compression and obstruction of gastric antrum and its adjacent organs.

Cause

Functional gastric retention is due to gastric atony. In addition, stomach dysmotility caused by stomach or other abdominal surgery, central nervous system diseases, neuropathy caused by diabetes, and vagus nerve cutting can cause this disease. Uremia, acidosis, hypokalemia, hypocalcemia, systemic or intra-abdominal infections, severe pain, severe anemia, and the use of antipsychotics and anticholinergic drugs can also cause this disease.

If there is vomiting and eating, if there is a sound of water in the abdomen on an empty stomach, that is, stomach retention. After 4 hours of eating, it was confirmed that food was taken from the stomach cavity from the stomach tube.

During gastrointestinal barium meal examination, the expectorant remained 50% after 4 hours, or was not empty after 6 hours, which is the evidence of this disease. Attention should be paid to the identification of organic and functional gastric retention. The former increased gastric peristalsis, the latter decreased gastric tension, and gastric peristalsis decreased.

Vomiting is the main manifestation of this disease, which can occur day and night, 1 to several times a day. Vomits are often used for food and generally do not contain bile. Upper abdominal fullness and pain are also common. Abdominal pain can be dull pain, colic or burning pain. Symptoms can be temporarily relieved after vomiting. Acute patients can cause dehydration and electrolyte metabolism disorders; chronic patients can have malnutrition and weight loss. Severe or long-term vomiting, due to the massive loss of gastric acid and potassium ions, can cause alkalosis, and cause convulsions in the hands and feet.

Physical examination showed dehydration, upper abdominal distension, middle and upper abdomen tenderness and accompanied by water sound. See the stomach type, and there is a gastric peristaltic wave enhancement from left to right, more suggestion that the stomach outlet is blocked; if only the stomach type is seen and there is no peristaltic wave, it indicates that the gastric tension is lacking.

Differential diagnosis

Attention should be paid to the identification of organic and functional gastric retention. The former has increased gastric peristalsis, and the latter has reduced gastric tension and less gastric peristalsis.
