Factors Associated with Redundant Sigmoid Colon at Mulago Hospital, Kampala

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)
Conclusion : 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.
