Introduction

Welcome to the gastrointestinal module. The principle objective of the

gastrointestinal module is to educate the student on the basic structure,

physiological and biochemical aspects of the gastrointestinal system.

This module is designed emphasizing the essential components and minimizing

the non-essential details. The students will get the opportunity of learning about

different types of gastrointestinal secretions and their contribution to digestion

and absorption. They will also learn about mechanisms of gut motility and

important disorders of gut motility like vomiting.

The goals of the entire system are to convert ingestible food to absorbable

particles and finally absorption. An important area of this module is to teach

how gastrointestinal system is regulated, to achieve the above goal.

In this module student is exposed to common gastrointestinal diseases like

diarrhoea, vomiting and jaundice. This exposure will help them to grasp the

fundamentals of the gastrointestinal diseases and relate them to the clinical

conditions in Phase II. For this purpose several case scenarios has been

included at the beginning of each section.

Furthermore active learning is facilitated by small group discussions, fixed

learning modules rather than didactic lectures.

Tutorials and small group discussions will enhance student’s comprehension,

evaluating capacity and reasoning ability. Students are given free time which

allow them to engage in academic activities as they wish. Activities that can be

carried out in the language lab has been identified including listening activities,

matching terms and definitions, cross words, puzzles, scenarios for role play

and to develop communication skills. Skills lab activities that can be done in

relation to gastrointestinal system are examination of the abdomen, insertion of

Nasogastric tube and digital examination of the rectum in models.

For convenience and practicality the GI module is arranged in an anatomical

manner starting from the mouth going down to the anus. The liver and the

pancreas would be separate sections .In each section the main and the

intermediate objectives would be laid down. The areas that the student should

know as essential core knowledge would be designated as (A) and good to

know and nice to know is depicted as (B) and (C) respectively.

We hope that at the end of the module the student could appreciate the

importance of GI physiology as a vital part of the human body and understand

how its functions relate to the functioning of the human body as a whole.

Jaundice Topic: Jaundice

Scenario:

Your mother phoned you from your hometown telling that your aunt has been

transferred to Kalubowila Hospital with abdominal discomfort. Your mother

wants you to see your aunts in the evening on the way to your boarding place.

She complained of abdominal discomfort and noticed that she looks tired and

yellow discolouration of eyes. You were lucky enough to see the bed head

ticket since you are a medical student. You notice that doctor has ordered the

following investigations.

Serum bilirubin

Aspartate transaminase

Alanine transaminase

Scenario:

Your friend in the boarding place developed diarrhea in the evening and you

took her to hospital. Doctor admitted her to Ward 9, Colombo South hospital.

She was given a normal saline drip.

You are interested in finding the reasons of your friend’s diarrhoea and reason

for giving a saline. The following day when you were visiting your friend, she

was feeling better. You want to find out the mechanism of development of
