Reactive gastropathy, abbreviated RG, a relatively common pathology of the stomach. It is also known as chemical gastropathy,[1] and incorrectly referred to as chemical gastritis (see below).
General
- May be seen in the context of a previous resection/surgical reconstruction, e.g. Billroth II.
Epidemiology
General assocations:
- Increases with age.[2]
Etologic factors - associated with:[3]
- Excess acid.
- Alcohol use (excessive).
- Bile (reflux).
- May be seen post-Bilroth II (distal gastrectomy).
- Drugs.[1]
- Iron (brown pigment on histology).
- NSAIDs - synergistic effect with corticosteroids.
Notes:
Drugs that cause erosions and/or ulcers - adapted from Genta:[1]
| Drug | Comment | Indication for Rx |
|---|---|---|
| NSAIDs | common cause | pain, reduce cardiovascular risk |
| Corticosteroids | synergistic effect with NSAIDs | rheumatologic diseases + others |
| Potassium (KCl) | common cause | renal failure |
| Bisphophonates | uncommon cause | osteoporosis |
| Ferrous sulfate | very common if symptomatic | iron deficiency anemia |
| Chloroquine | uncommon | only in the context of malaria |
| Sodium polystyrene sulfonate (Kayexalate) | rare | renal failure patients |
Relation to gastritis
- May mimic a (true) gastritis symptomatically and visually in an endoscopic examination.
- "Chemical gastritis" is misnomer. Etymologically, the -itis in gastritis, implies an inflammatory process. Chemical gastropathy is not (predominantly) an inflammatory process.
- This type of confusion is not uncommon. Steatohepatitis is another example of this; it is not a process with significant inflammation yet, confusingly, carries the -itis ending.
Gross/endoscopic
Features:[5]
- Antral erythema +/- erosions.
- +/-Bile.
Microscopic
- Foveolar hyperplasia.
- Tortuosity of glands in the "neck" region of the gastric glands.
- Associated with "mucin depletion" - cytoplasm not clear -- as is usual.
- Smooth muscle fibre hyperplasia.
- Abundant eosinophilic lamina propria.
- Scant acute & chronic inflammatory cells.
Additional features.
- +/-Edema.
- +/-Erosions.
Notes:
- Triad rarely present; mild inflammation common.

STOMACH, BIOPSY: - ANTRAL-TYPE GASTRIC MUCOSA WITH REACTIVE GASTROPATHY, SEE COMMENT. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR HELICOBACTER-LIKE ORGANISMS. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY. COMMENT: This nonspecific finding may be due to a number of causes, including medications (especially NSAIDs), alcohol and bile reflux.
RG and mild chronic gastritis
STOMACH, BIOPSY: - ANTRAL-TYPE GASTRIC MUCOSA WITH REACTIVE GASTROPATHY AND MILD CHRONIC INACTIVE INFLAMMATION. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR HELICOBACTER-LIKE ORGANISMS. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY.
Not well-developed
STOMACH, BIOPSY: - BODY-TYPE GASTRIC MUCOSA WITHIN NORMAL LIMITS. - ANTRAL-TYPE GASTRIC MUCOSA WITH SMOOTH MUSCLE HYPERPLASIA, RARE GLAND TORTUOSITY AND NO SIGNFICANT INFLAMMATION, SEE COMMENT. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR HELICOBACTER-LIKE ORGANISMS. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY. COMMENT: These findings are suggestive of a reactive gastropathy; however, gland corkscrewing is not evident.
Not well-developed with minimal inflammation
STOMACH, BIOPSY: - ANTRAL-TYPE GASTRIC MUCOSA WITH SMOOTH MUSCLE HYPERPLASIA, RARE GLAND TORTUOSITY AND MINIMAL CHRONIC INACTIVE INFLAMMATION, SEE COMMENT. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR HELICOBACTER-LIKE ORGANISMS. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY. COMMENT: The smooth muscle hyperplasia and rare gland tortuosity are suggestive of a reactive gastropathy.
Isolated smooth muscle prominence
STOMACH, BIOPSY: - ANTRAL-TYPE GASTRIC MUCOSA WITH PROMINENT SMOOTH MUSCLE, OTHERWISE WITHIN NORMAL LIMITS. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR HELICOBACTER-LIKE ORGANISMS. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY.
