Diagnosis and Management of Gastric Ulceration

Diagnosis

The World Journal of Emergency Surgery recommends endoscopy as the first-line diagnostic approach for gastric ulceration, followed by testing for H. pylori infection and implementation of appropriate medical therapy including proton pump inhibitors and H. pylori eradication when indicated 1, 2
Endoscopy is the gold standard for diagnosis of gastric ulceration, allowing direct visualization of ulcers and collection of biopsies 3, 1
Risk stratification using Blatchford score is recommended to determine timing of endoscopy, with very low-risk patients undergoing outpatient endoscopy, low-risk patients undergoing early inpatient endoscopy, and high-risk patients undergoing urgent inpatient endoscopy 4

The World Journal of Emergency Surgery recommends initial resuscitation for bleeding ulcers, including maintaining hemoglobin >7 g/dL, targeting systolic blood pressure 90-100 mmHg, normalizing lactate and base deficit, and correcting/preventing coagulopathy 4, 5
Proton pump inhibitors are recommended for 6-8 weeks following endoscopic treatment of bleeding ulcers 1
Endoscopic treatment is recommended for spurting ulcers, oozing ulcers, and ulcers with non-bleeding visible vessels, with dual modality endoscopic hemostasis suggested 5
The World Journal of Emergency Surgery recommends non-operative management as first line after endoscopy for bleeding ulcers, with emergency endoscopy as first-line management for recurrent bleeding 2, 1

CT scan is strongly recommended as first radiological examination for suspected perforated ulcers, with surgical intervention typically required 6
Transcatheter angioembolization is suggested as alternative when endoscopy fails or isn't feasible for bleeding ulcers 2

Long-term acid suppression therapy is beneficial for chronic NSAID users and H. pylori-infected patients 1
Failure to test for H. pylori in all patients with gastric ulcers is a common pitfall 1
Performing angiography before endoscopy results in unacceptable rates of negative investigations 2

Biopsy of all gastric ulcers is mandatory to exclude malignancy, as gastric ulcers cannot be reliably distinguished as benign by appearance alone, according to the World Journal of Emergency Surgery 7
Multiple biopsies should be obtained from the ulcer margin and base, as recommended by Gut 8

All patients with gastric ulcers must be tested for H. pylori infection, according to the Annals of Internal Medicine 9
Non-invasive testing methods for H. pylori infection include urea breath test and stool antigen test, as reported by Gut 10 and Gut 11
Negative H. pylori tests obtained during acute bleeding should be repeated, as acute bleeding can cause false-negative results, according to the Annals of Internal Medicine 9

Eradicate H. pylori with combination therapy, which reduces ulcer recurrence from 50-60% to 0-2%, as recommended by the Annals of Internal Medicine 9
Confirm eradication of H. pylori after treatment, according to the Annals of Internal Medicine 9
Administer high-dose PPI therapy, which is essential for healing and preventing recurrence, as recommended by the Annals of Internal Medicine 9

All gastric ulcers require repeat endoscopy at approximately 6 weeks to confirm healing and exclude malignancy, as recommended by Gut 8
Continue PPI therapy until repeat endoscopy confirms healing, according to Gut 8
Patients requiring continued NSAID therapy should receive ongoing PPI therapy, as recommended by the Annals of Internal Medicine 9

Failing to biopsy gastric ulcers is the most critical error, as malignancy cannot be excluded without histology, according to the World Journal of Emergency Surgery 7 and Gut 8
Treating empirically without endoscopy delays definitive diagnosis and risks missing gastric cancer, as reported by Gut 10 and Gut 11
Using H2-receptor antagonists instead of PPIs results in inferior healing rates, according to the Annals of Internal Medicine 9
