Abstract:
Endoscopy is the gold standard for evaluating caustic-induced gastric mucosal injury. Injuries ≥ 2b (confluent ulceration or charring) are associated with perforation and cicatrisation. Grade 1-2a injuries recover without intervention. Grade 2b and 3 injuries require observation and may need intervention. (99m)Tc-pertechnetate imaging can assess gastric viability after caustic injury. We correlated (99m)Tc-pertechnetate SPECT/CT with endoscopic findings in 4 patients with increasing grades of caustic-induced gastric mucosal injury.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
