Management of a 61-Year-Old Man with New-Onset Indigestion and Weight Loss
Upper GI endoscopy is the most appropriate next step for this 61-year-old man with new-onset indigestion and weight loss, despite normal physical examination and blood tests.
Rationale for Upper GI Endoscopy
The American Gastroenterological Association (AGA) guidelines clearly recommend endoscopy for patients older than 55 years of age presenting with new-onset dyspepsia and for younger patients with alarm features 1. This patient has two critical factors that warrant immediate investigation:
- Age > 55 years (61 years old)
- Presence of an alarm feature (weight loss)
The AGA guidelines specifically state that "the value of alarm symptoms in younger patients is controversial. A systematic review of alarm symptoms suggests that these are not very useful in diagnosing upper gastrointestinal malignancy. However, although the yield of endoscopy is low, it is recommended for patients older than 55 years of age and for younger patients with alarm features (eg, weight loss, progressive dysphagia, recurrent vomiting, evidence of gastrointestinal bleeding, or family history of cancer) presenting with new-onset dyspepsia" 1.
Clinical Decision Algorithm
Patient characteristics:
- 61-year-old man (age > 55)
- New-onset indigestion (2 months duration)
- Weight loss (alarm symptom)
- Normal abdominal examination
- Normal blood tests (CBC, RET, LFT, CRP)
Decision pathway:
- Age > 55 years OR alarm symptoms present → Upper GI endoscopy
- Normal blood tests do not rule out significant pathology in this age group with alarm features
Why Upper GI Endoscopy is Superior to Other Options
Upper GI endoscopy (Option A) allows direct visualization of the mucosa, biopsy capability, and has greater diagnostic accuracy than radiographic studies 1. It is the gold standard for evaluating upper GI symptoms with alarm features.
Routine abdominal US (Option B) has lower sensitivity for detecting upper GI pathology and would likely be followed by endoscopy regardless of findings.
Abdominal and erect X-ray (Option C) has poor sensitivity for detecting mucosal abnormalities and would not adequately evaluate for conditions like gastric cancer or peptic ulcer disease.
Routine referral to Gastroenterology (Option D) would ultimately lead to endoscopy scheduling but would unnecessarily delay diagnosis in a patient with alarm features.
Important Clinical Considerations
The UK Department of Health guidelines for oesophago-gastric cancer specify that patients with new-onset dyspepsia over 55 years should receive urgent referral for gastroscopy 1.
Approximately 70% of patients with early gastric cancer have symptoms of uncomplicated dyspepsia with no associated anaemia, dysphagia or weight loss 1. However, this patient has weight loss, increasing concern for malignancy.
Clinical diagnosis is very inaccurate in distinguishing between organic and non-organic disease, necessitating endoscopic evaluation in at-risk patients 1.
The normal blood tests, including normal CRP, do not exclude significant pathology such as malignancy, as early cancers may not cause systemic inflammatory response 2.
Upper GI endoscopy should be performed by an experienced endoscopist, with multiple biopsies taken if any abnormalities are found, and testing for H. pylori should be performed during the procedure 1.
