About Pediatric Gastroenterology, Hepatology & Nutrition of Florida

Pediatric Gastroenterology, Hepatology and Nutrition of Florida, P.A. provides comprehensive evaluation, diagnostic procedures and therapy for infants, children and adolescents with disorders of the stomach, intestines, colon, liver, pancreas and nutrition.  The group was started in 1983 by Daniel T. McClenathan, M.D. in St. Petersburg, Florida and currently includes twelve Pediatric Gastroenterologists and twelve Nurse Practitioners.  Our physicians have all completed three years of residency training in Pediatrics and three additional years of training in Pediatric Gastroenterology and Nutrition.

Our mission is to provide exceptional care to our patients, families and Pediatricians.  We offer multiple office locations convenient to twenty-two counties stretching from Ocala to Naples and from Orlando to the Gulf of Mexico.  We also treat patients in consultation from throughout the U.S. as well as Central and South America.

All of our physicians are proficient diagnosticians, a skill essential for the accurate evaluation of our patients with abdominal pain, poor weight gain, vomiting, diarrhea and constipation.  Most children occasionally experience one or more of these symptoms.  Some children, however, develop recurrent symptoms, which interrupt their normal life, inhibit their development, disrupt their school performance and affect their emotional well being and self-esteem.

We also have broad experience with complex, less common disorders including:

• Chronic abdominal pain, diarrhea, constipation and vomiting
• Inflammatory bowel disease
• Crohn’s disease
• Celiac disease and other forms of chronic diarrhea and malabsorption
• Gastrointestinal bleeding
• Acute and chronic liver disease including hepatitis and disorders requiring liver transplantation
• Neonatal liver disease
• Acute and chronic pancreatitis
• Biliary tract disease
• Short-bowel syndrome
• Complex nutritional problems requiring specialized tube feeding
• Helicobacter pylori infection causing gastritis and duodenal ulcer
• Gastrointestinal manifestations of cystic fibrosis

Some of the diagnostic and therapeutic procedures performed by our physicians include:

• Upper gastrointestinal endoscopy with biopsies
• Colonoscopy, flexible sigmoidoscopy and small bowel enteroscopy with biopsies
• Dilation of esophageal and colonic strictures
• Endoscopic electrocautry, heat ablation and laser therapy of bleeding lesions in the stomach, duodenum and colon
• Endoscopic polypectomy
• Esophageal variceal sclerotherapy and variceal banding
• Foreign body recovery from the esophagus and stomach
• Gastojejunostomy tube placements
• Percutaneous endoscopic gastrostomy (PEG)
• Percutaneous liver biopsy
• Prolonged intraesophageal pH monitoring
• Video capsule endoscopy
