Expert Treatment for Rectal Cancer by Dr. Bharat Pothuri

Dr. Pothuri uses a step-by-step approach:

Medical History and Exam

He reviews your symptoms (onset, duration, quality), dietary habits, medication use (NSAIDs, alcohol), and risk factors for GERD, ulcers, or pancreatic disease.

Blood Tests

We check complete blood count (for anemia), liver enzymes (AST, ALT), pancreatic enzymes (amylase, lipase), and H. pylori serology or stool antigen when ulcer is suspected.

Imaging Studies

  • Abdominal ultrasound to evaluate gallbladder stones, liver pathology, or pancreatic enlargement.
  • Upper endoscopy (EGD) to directly visualize the esophagus, stomach, and duodenum-biopsies can be taken for H. pylori or celiac disease.

Advanced Testing (if needed)

pH monitoring or esophageal manometry for refractory reflux; gastric emptying study if gastroparesis is suspected; CT/MRCP to assess pancreatic or biliary anatomy.
