Abstract

Background: Sigmoid Volvulus is the most common form of Volvulus of the gastrointestinal tract and in Uganda; this condition is one of the top causes of intestinal obstruction. It is associated with a pre-existing redundant sigmoid colon which has a narrow attachment of the sigmoid mesentery to the posterior abdominal wall. The objectives of this study was to establish the demographic, dietary and socio-economic factors associated with redundant sigmoid.

Methods: A case-control study comparing demographic, dietary and socio economic factors between 68 patients diagnosed with redundant sigmoid colon, and 136 controls in Mulago Hospital from May to December 2006 was undertaken.

Results: The majority (64.7%) of the patients with redundant sigmoid colon were aged between 30 and 70 years with a male to female ratio of 5:1. Statistically significant association was observed between redundant sigmoid colon and consumption of cereals, fruits and fats (OR 1.5-2.9, P=O.OO) and irregular bowel habits (OR = 4.9, P = 0.00). The majority (57.4%) of cases of cases were peasants. There was no statistically significant association between sex and redundant sigmoid colon (P = 0.45; 95% C.I = 0.6 – 2.8). Neither was there a statistically significant association between the level of education and redundant sigmoid colon (P = 0.07; 95% C.I = 0.6 – 0.9)

Conclusions: Redundant sigmoid colon was common among the young and middle age groups and predominantly occurred in males. There was an association between redundant sigmoid colon and consumption of cereals, fruits and fats. People with irregular bowel habits were about five times more likely to have redundant sigmoid colon than those who had regular bowel habits. Majority of patients with redundant sigmoid colon were of low socioeconomic status.
