Clinicopathological features and management of obstructive jaundice at Queen Elizabeth Central Hospital, Malawi. A retrospective cohort analysis.

Introduction: The diagnosis of obstructive jaundice (OJ) is a challenge and is often made late especialy in low-resource settings. There is a paucity of data on the aetiology and prognosis of patients with obstructive jaundice in Malawi and Sub-Saharan Africa. The objective of this study was to determine the aetiology, clinical presentations, and short-term treatment outcomes of patients managed for OJ in Malawi. Methodology: A review of case notes of all patients admitted with a clinical diagnosis of OJ from 2012 to 2022 was done. We reviewed the clinical presentation, laboratory findings, management, intra and post-operative complications, and patient outcomes. Data was entered into an Excel spreadsheet and analysed using SPSS version 25. Results: Of 26,796 patient admissions, 5339 (19.9%) were for non-trauma abdominal symptoms, of which 164 (0.6% of surgical admissions and 3% of abdominal symptoms) were for obstructive jaundice. Ages varied from 16 to 89 years. Females were 45 (58.4 %) of the population. The commonest presenting complaint was jaundice followed by abdominal pain and distention. The mean duration of symptoms at presentation was 8.5 weeks. The most frequent imaging modality was abdominal ultrasound 50(65 %). Twenty-six patients (33.8 %) were discharged with a diagnosis of obstructive jaundice of undetermined pathogenesis. The commonest diagnosis was pancreatic cancer 20(26.0 %) followed by Choledocholithiasis11(14.3 %). Patients younger than 50 years had the same likelihood of presenting with cancer as those older than 50 years. Conclusion: It is important to have a high index of suspicion in all adult patients presenting with obstructive jaundice as patients younger than 50 years have a similar risk of malignancy as older patients.
