Upper Gastrointestinal Surgical Disease
Evaluate dysphagia, perforation and gastric obstruction using alarm features and physiological priorities.
Quick revision ↓ Medical Dictionary
01Characterise dysphagia
Distinguish difficulty initiating swallowing from food sticking after swallowing. Progressive solids then liquids dysphagia suggests a mechanical process, while symptoms with both from the outset can suggest motility disease, although overlap exists. Weight loss, bleeding or rapidly progressive symptoms require prompt investigation. Aspiration and inability to handle secretions alter urgency. Do not label persistent dysphagia as uncomplicated reflux without an appropriate assessment.
02Select diagnostic tests
Endoscopy permits inspection and tissue sampling for many structural lesions. Contrast studies and physiological tests have selected roles, often after specialist assessment. Suspected perforation changes the investigation pathway and requires care with instrumentation. A biopsy result should be interpreted with endoscopic and imaging findings; a nondiagnostic sample does not necessarily end investigation of a clearly suspicious lesion.
03Recognise perforation
Sudden severe pain, peritonism or systemic compromise can indicate perforated peptic ulcer or another gastrointestinal perforation. Free gas supports the diagnosis but its absence does not exclude every perforation. Resuscitate, provide appropriate antimicrobial and acid-suppression care through the pathway, and obtain urgent surgical review. Management depends on stability and anatomy; a temporary reduction in pain is not proof that contamination has stopped.
04Assess gastric outlet obstruction
Persistent vomiting of retained food, early satiety, dehydration and weight loss can suggest gastric outlet obstruction. Electrolyte depletion and aspiration risk require attention before definitive investigation or intervention. Benign ulcer-related narrowing and malignancy are possible causes. Decompression and correction of deficits may be needed under supervision, followed by endoscopic and imaging evaluation rather than repeated antiemetics alone.
05Plan treatment and follow-up
Management can involve acid suppression, eradication of confirmed Helicobacter pylori, endoscopic therapy or surgery depending on the diagnosis. Gastric ulcers and suspicious lesions need appropriate biopsy and follow-up plans. Discuss nutrition and swallowing safety while work-up proceeds. For cancer, stage the disease and use multidisciplinary planning rather than deciding resectability from the symptom pattern alone.
High-Yield Revision
- Progressive dysphagia is an alarm symptom.
- Absence of free gas does not exclude every perforation.
- Correct dehydration and electrolyte losses during obstruction assessment.
Common Pitfalls
- Do not treat persistent dysphagia indefinitely as reflux without investigation.
- Do not assume a nondiagnostic biopsy overrides a suspicious lesion.
