An engorgement and prolapse of the anal cushion lead to haemorrhoidal disease. There are different anatomical sites and presentation of this common pathology which affects the quality of life.


To study the predilection sites, presentation and treatment of haemorrhoidal disease.

Patients and Method:

A cohort study of patients diagnosed with haemorrhoids at an Endoscopy centre in Port Harcourt, Rivers State Nigeria from February 2014- July 2017.The patients were divided into 2 groups: A - asymptomatic and B- symptomatic. Variables studied included: demographics, anatomic variations, grade of haemorrhoids, clinical presentation and treatment. Statistical analysis was performed using IBM SPSS Statistics for Windows, version 20.0. Armonk, NY.


One hundred and twenty- one cases were included in study. There were 76 males and 45 males with age range from 15 -80 years (mean 51.9±13.1yrs). Bleeding per rectum was the most common presentation. The position frequency of haemorrhoids in decreasing order were: right posterior (34.1%); right anterior (28.2%); left lateral (17.1%); left posterior (7.6%). Multiple quadrants were affected in 58(72.5%) cases of external haemorrhoids. Grade I, II and III haemorrhoids were seen in 38 (31%), 31(26%) and 21(17%) cases respectively.


The most common anatomical site of external haemorrhoids is the right posterior quadrant position; frequently, multiple sites are simultaneously affected. Goligher classification Grade 1 hemorrhoids are effectively treated by injection sclerotherapy using 50% dextrose solution; a cheap and physiologic sclerotherapy agent.
