Abdominal Pain in Adult Sickle Cell Disease Patients: A Nigerian Experience

Background: Abdominal pain is a relatively frequent occurrence in sickle cell disease. The aetiology of abdominal pain in sickle cell disease is often difficult to diagnose clinically. Despite the frequent occurrence, diagnostic dilemma, and the need for an accurate, early diagnosis, abdominal pain insickle cell disease has not been rigorously studied.Objective: We therefore sought to describe the different presentations and patterns of abdominal pain in persons with sickle cell disease.Methods: A prospective case series of 20 patients was done in which data was collected on demographic characteristics, hemoglobin electrophoresis patterns, a description of the abdominal pain including sites, severity, and type of pain, packed cell volume and the provisional and final diagnosis.Results: Haemoglobin S patients were 17 in number constituting eightyfive percent (85%) of our study population whilst the rest 3 were Hb S+C. Most patients (70%) had one site of abdominal pain. The pain was mainly colicky or tightening, moderate to severe in nature and, in some cases, associated with vomiting. We did not find any significant difference between the steady state PCV and the PCV during the acute abdominal pain episodes. The final diagnosis showed that only 38.8% of the patientshad vasoocclusive crises and the reliability index between the provisional diagnosis and the final diagnosis was 67%.Conclusion: Abdominal pain in sickle cell disease may present in different ways and it is important to recognize that the possible diagnoses are numerous. Not all cases are due to vasoocclusive crises. Early diagnosisand prompt treatment can be life saving.Keywords - Abdominal Pain, Sickle Cell Disease, Anaemi
