Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy: experience in the Sudan

Over a 5 year period 626 endoscopic retrograde cholangiopancreatography (ERCP) examinations were attempted in Khartoum, Sudan. The relevant duct was successfully cannulated and visualized in 94% of cases of biliary tract disease and in 73% of cases of pancreatic disease. This was due to the large number of cases with advanced pancreatic cancer. The commonest abnormal finding was stones in the biliary tree in 214 cases (35% of all cases). Cholangiocarcinoma was seen in 18 cases, pancreatic cancer in 64 cases, chronic pancreatitis in 48 cases and periampullary carcinoma in 20 cases. ERCP was considered normal in 100 cases. Endoscopic sphincterotomy (EST) was performed in 48 cases; 44 had common duct stones. ERCP and EST are feasible and useful procedures in a developing country. However they are expensive and should be carried out in referral centres.
