ABSTRACT
Aim: To determine the
gender wide distribution of the characteristics of colorectal polyps among the
patients who underwent sigmoidoscopy at Liver Clinic, Lahore, Pakistan.
Methods: This retrospective
analysis was carried out on the data of the patients who were diagnosed as
having colorectal polyps during sigmoidoscopy from February 2010 to July 2017
at Liver clinic, 250 Shadman Lahore. The entire data was evaluated on SPSS
version 25. Chi-square test for independence and Independent sample T-test were
applied on qualitative and quantitative variables respectively to determine
their significant association with the gender. Then, binary logistic regression
analysis was also performed. The p-values were taken statistically significant
if < 0.05.
Results: Out of total of 82
patients having colorectal polyps, 73.2% male and 28.8% were female. The mean
age of the male patients was 36.78±18.99 years while the mean age of the female
patients was 39.59±16.39 years. There was no significant difference in the age
of the two groups of the patients (p = 0.541). The mean distance of the polyp
from anal verge in male patients was 16.88±8.35 cm while the mean distance of
the polyp from anal verge in female patients was 22.09±12.75 cm. The polyps
were significantly closer to anal verge in male gender as compared to female
gender (p=0.034). The gender of the patients had no statistically significant
association with presenting complaints (p=0.774) and presence of the stalk of
polyp (p=0.429). The male patients had polyps significantly in their rectum
(p=0.024), and solitary (p=0.035). Binary logistic regression model was
significant, p<0.05. It explained 21.4% (Nagelkerke R2) of the variance in the gender wise grouping of
patients and correctly classified 75.6% of cases. Male had 3.092 times more
likelihood risk of finding a polyp in the rectum as compared to female.
Conclusion: colorectal polyps are found
in both male and female gender during sigmoidoscopic examination. these are
solitary and frequently inside the rectum among the males as compared to the
female gender. gender has no association with age, presentation complaints, and
presence of the stalk of the polyp among the studied pakistani population
Keywords: colorectal polyps, gender,
sigmoidoscopy, pedunculated, sessile
