Demographic Profile of Patients Undergoing Colonoscopy at a Tertiary Care Centre in Central Nepal

Abstract

Introduction: Colonoscopy is one of the useful diagnostic tool to evaluate lower gastrointestinal tract. Theaim of this study was to evaluate patient characteristics, common symptoms, colonoscopicfindings and histopathology findings by reviewing colonoscopy procedures.
 Methods: This was a retrospective study conducted at College of Medical Sciences and teaching hospital, Bharatpur, Nepal over a period of three years (1st January 2017 – 31st December 2019). Census sampling method was used to retrieve the data. Patients characteristics, indications, duration of symptoms and findings were retrieved from the endoscopy record register and histopathology finding of those patients whose biopsy were taken were retrieved from the pathology department record file. 
 Results: Over a three years period 324 colonoscopy were reviewed.The mean age of the study populationwas 48.77+/-17.35 years. Male to female ratio was 1.38:1. The most common indication forcolonoscopy was pain abdomen with mucus in stool in 25.3% patients followed by bleedingper rectum in 21.3% patients. Other than normal colonoscopy the most common findings wereHaemorrhoids in 20.1% patients and inflammatory or ulcerative lesions in 17.6% patients.Colorectal malignancy was seen in 6.48% patients. Colonoscopic biopsy was done in 114patients. The common biopsy findings were ulcerative colitis in 12.7%, adenomatous polypin 6.8%, adenocarcinoma in 6.5% of the total study patients.Poorly differentiated carcinomawas found more in the younger age group and males were more commonly affected withcolorectal cancers than females.Conclusions: The most common indication for colonoscopy was pain abdomen with mucus in stool in25.3% patients.

Demographic and clinical profile of patients undergoing colonoscopy at a tertiary care center in Nepal: a retrospective cross-sectional study

“…We found that the mean age of the patients who underwent colonoscopy was 43.8 years, which is comparable to other similar studies done in Nepal 5 – 7 . However, the median age of patients undergoing colonoscopy was reported to be 62.5 years in a study done in the USA, 57 years in a general hospital in the UK and 59 years in a study done in South Korea 10 – 12 .…”
