2.5 AGE GROUPS
The large majority of patients undergoing GI endoscopy were between 50-60 years of age 24.33 and 60-70 years of age 22.26 Table 2.5.This was followed by the 40-50 year
age group 16.41 and the 70-80 year age group 15.67.The mean age was 55.2 while the median age was 56.8 years. Middle-aged and elderly adults therefore contributed to the
bulk of the endoscopy workload. This has important implications in the context of a rapidly aging population. Young adults accounted for a smaller proportion of endoscopies viz. 30-40
years 8.54 and 20-30 years 6.48. The adolescent population, i.e. 10-20 year age group, accounted for 2.19 while the paediatric age group below the age of 10 accounted for only
0.28. Paediatric gastroenterology is only beginning to evolve in Malaysia.

2.6 TYPE OF ENDOSCOPIC PROCEDURES PERFORMED
A total of 16 447 endoscopic procedures were performed over the 9 month period from September 2008 till May 2009 in these 6 centres. Of these the vast majority 60.95 were
OGDS Oesophagogastroduodenoscopies while colonscopies accounted for 27.49 Table 2.6
. ERCP accounted for 7.05 while EUS accounted for only 3.74. Other procedures , which include enteroscopy and capsule endoscopy, only accounted for only 0.77. Hence the majority
of GI endoscopic procedures revolved mainly around upper and lower GI endoscopies. This appears to be the pattern of practice.
