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
