Obscure jaundice is often a diagnostic dilemma and needs elaborate investigation protocols. A retrospective, observational study was carried out on 291 patients who underwent diagnostic ERCP at the department of Gastrointestinal Endoscopy, Military Hospital, Rawalpindi during the period 1991-95. ERCP was successfully performed in 244 cases, whereas in 47 cases successful cannulation was not possible. 82 patients had normal findings while 162 had gross pathological findings that included 64 cases with stones, 39 cases with strictures and 28 cases with carcinoma. The ducts were obstructed in 18 cases, dilated in six and did not opacify in another six. ERCP is thus an economical means of getting safe and conclusive diagnostic yield in cases of obscure jaundice.
