This sounds like post-corrosive gastric outlet obstruction (GOO) after acid ingestion, with a feeding jejunostomy (FJ) already in place. She should be managed by an upper-GI surgeon and therapeutic gastroenterologist at a center experienced with corrosive strictures.
Immediate priorities
- Continue jejunostomy feeding to correct malnutrition, dehydration, anemia, low albumin, and electrolyte deficits. The FJ is a bridge to recovery or definitive treatment, not necessarily the final treatment.
- Assess for aspiration, ongoing vomiting, GI bleeding, severe pain, fever, or peritonitis. These need urgent hospital assessment.
- Check CBC, renal function, electrolytes, liver profile, albumin/prealbumin, glucose, and correct deficiencies.
- Do not give oral feeds if she has complete obstruction or recurrent vomiting unless the treating team confirms it is safe.
- Acid suppression can be used for associated gastritis/reflux, but it will not reverse a fixed cicatricial stricture.
- Steroids are not useful for established corrosive strictures. Harrison’s notes that glucocorticoids have not improved outcomes in acute corrosive injury.
Define the anatomy before choosing treatment
Once stable and after the acute inflammatory phase, the usual work-up is:
- Upper GI endoscopy, performed carefully by an experienced endoscopist: define site, length, severity of pyloric/antral/duodenal stricture; inspect esophagus too.
- Contrast upper-GI study using water-soluble contrast initially if perforation is a concern, then barium if appropriate: maps the stricture and gastric dilatation.
- CT abdomen if there is concern for complex disease, extrinsic pathology, perforation, or uncertainty about the level/extent of obstruction.
- At age 60, obtain adequate evaluation/biopsy of suspicious lesions to exclude an unrelated or coexisting malignancy, particularly if the appearance is atypical or weight loss is disproportionate.
Definitive treatment options
Choice depends mainly on stricture length and location, condition of the stomach/duodenum, esophageal involvement, nutritional status, and local expertise.
| Finding | Usual approach |
|---|---|
| Very short, localized pyloric/prepyloric stricture with healthy surrounding tissue | Careful endoscopic balloon dilatation may be attempted in selected cases, often requiring repeated sessions |
| Short localized distal gastric/pyloric stricture, unsuitable for or failing dilatation | Pyloroplasty/stricturoplasty can preserve normal gastric passage |
| Long distal gastric stricture, extensive antral disease, or stricture reaching duodenum | Gastrojejunostomy, often Roux-en-Y, is commonly preferred |
| Severely scarred/nonfunctional stomach or suspicion of dysplasia/malignancy | Selected patients may need distal gastrectomy, but this is more extensive and individualized |
| Significant concurrent esophageal stricture | Treat as a combined problem, often serial esophageal dilatation plus gastric bypass/repair as needed |
A surgical series of corrosive GOO found that localized pyloric/antral strictures were treated with stricturoplasty, while longer distal gastric or duodenal disease was treated with loop or Roux-en-Y gastrojejunostomy. It also supports maintaining nutrition through FJ before definitive surgery. See this corrosive GOO surgical review.
Practical recommendation for this patient
Because she already has an FJ, the next step is usually:
Optimize nutrition through FJ -> endoscopy plus contrast study to map the stricture -> discuss definitive intervention in a multidisciplinary upper-GI meeting.
For a 60-year-old with established, symptomatic obstruction from acid injury, a durable surgical procedure is often needed, especially if the stricture is long, severe, or not amenable to safe balloon dilatation. If it is a short isolated pyloric stricture, carefully planned balloon dilatation or pyloroplasty may be reasonable.
Seek urgent care now if
- FJ blockage, leakage, dislodgement, surrounding redness/pus, or severe pain
- Persistent vomiting despite FJ
- Fever, tachycardia, new severe abdominal pain/distension
- Hematemesis, melena, reduced urine output, confusion, or severe weakness
This is general medical information, not a substitute for operative planning. The endoscopy and contrast-study findings are what determine whether she is best served by balloon dilatation, pyloroplasty, or gastrojejunostomy.
