Foreign body in stomach

Introduction Foreign body in stomach is divided into exogenous, endogenous and foreign body formed in the stomach, namely stomach stone disease. 20% to 30% of the foreign matter swallowed is blocked and trapped in the esophagus. More than 80% of the foreign body in the stomach can be discharged from the stomach cavity by itself, and it is excreted from the bowel movement from the intestines. It rarely causes discomfort or only mild upper abdominal pain, fullness, nausea and other symptoms.

Cause

(1) Causes of the disease

Exogenous foreign body swallows foreign bodies into the stomach, which is not uncommon in clinical practice. There are various foreign bodies, such as buttons, dentures, pins, coins, pushpins, keys, animal bone spurs, etc., and foreign bodies left in the stomach cavity during surgery. (such as instruments, sterile gauze, etc.) can also be seen, endogenous foreign bodies through the pylorus through the penetration of the mites, the gallbladder perforation into the duodenum to move gallstones into the stomach.

(two) pathogenesis

1. Inadvertently or deliberately swallowed: Mistakes are more common in children, such as mistaking small toys, small hairpins, keys and coins, etc. Adults are more likely to have dentures, animal bones, etc., deliberately swallowing common criminals, mental disorders The swallowed foreign objects are various, such as pens, sewing needles, lighters, nails, broken glass and toothbrushes.

2. Medical source: including surgical residual sutures, drainage tubes, etc.

3. Stomach stone: including plant, animal, drug and mixed 4, clinically eaten persimmon, black dates, hawthorn and other plant-based gas stones are more common, prone to indigestion, stomach cramps, stomach In patients with reduced gastric motility after major resection, when a large number of persimmons are eaten on an empty stomach, the citric acid in the persimmon is combined with the protein and the protein is a protein that binds to the protein and is not easily soluble in water. In the stomach, citrate protein, gum, and fruit acid bind persimmon skin, persimmon nucleus, and plant fiber to form stomach persimmon.

Diagnosis: 20% to 30% of the foreign body that is swallowed is blocked and retained in the esophagus. More than 80% of the foreign body in the stomach can be discharged from the stomach cavity by itself. It is excreted from the stool from the intestines, rarely causing discomfort or only slight. Upper abdomen pain, fullness, nausea and other symptoms, when the foreign body is large, can be embedded in the pylorus, duodenal jejunum, ileocecal valve and other parts, when foreign bodies are blocked in the pylorus, the patient often feels abdominal pain, bloating, vomiting Foreign body damage to the gastrointestinal mucosa, or long-term impaction, causing local mucosal erosion ulcer, can lead to gastrointestinal bleeding, when the foreign body causes perforation, the patient will have peritonitis performance, needle sharp foreign body can pierce the gastrointestinal wall Forming a small abscess or granuloma, it is also possible to penetrate the gastrointestinal wall and move to the abdominal cavity and other parts.

The diagnosis of gastric foreign body is not difficult. The foreign body that is swallowed often has a history of accidentally ingesting the item in the mouth. The metal foreign object can be X-rayed to determine whether there is any foreign matter and its position. Non-metallic foreign objects can only be used with X-ray. Confirmed by barium meal or gastroscopy.

Differential diagnosis

Differential Diagnosis: Gastric foreign body is generally diagnosed based on medical history and X-ray or gastroscopy. Chronic gastric persimmon patients, due to long course of disease, symptoms are often similar to chronic gastritis, ulcer disease or gastric cancer, but it is easy to distinguish with the above diseases by X-ray barium angiography or gastroscopy.
