Gastroenterology

Introduction

Gastroenterology is the branch of medicine which deals with study of digestive system and management of its disorders. Sometimes Hepatology i.e. study of liver and bile system is also discussed under the same topic.

Diseases primarily affecting mouth and oro-pharynges are deemed more appropriate for School of Dentistry. Similarly, most conditions presenting as Acute abdomen as well as disorders affecting Ano-rectal area will be described under Surgery. Diseases related to developmental anomalies will be covered in details under Pediatrics.

ICD 10 Disease classification is not strictly followed for ease of discussion.

Learning Projects

See: Learning Projects and the Wikiversity:Learning model.

Learning materials and learning projects are located in the main Wikiversity namespace. Simply make a link to the name of the learning project (learning projects are independent pages in the main namespace) and start writing! We suggest the use of the learning project template (use "subst:Learning project boilerplate" on the new page, inside the double curved brackets {{}}).

Learning materials and learning projects can be used by multiple departments. Cooperate with other departments that use the same learning resource.

• Understanding Physiological principles involved in digestion, absorption, secretion and gut motility
• Understanding Presentation, Diagnosis and Management of gastrointestinal diseases.
• Investigative tools and procedures involved in diagnosis and Management
  • Gastrointestinal Imaging
  • Understanding Endoscopy
• How to approach a patient with Gastrointestinal Diseases
• Clinical case scenario and data interpretation
• Gut and Immune system
