No single pathophysiologic factor has been identified as the cause of recurrent acute @entity788 . A systematic search should be undertaken in every @entity1 to identify one of a myriad of factors that have been shown to play a part in causing this distressing illness. The abuse of @entity167 remains the likeliest cause, and further research may reveal an @entity2246 that jeopardizes some @entity1 . @entity253 , @entity5990 , @entity2941 , @entity1377 , and duodenal diverticula show a clear relationship. @entity209 such as @entity2741 , @entity407 , and @entity2742 remain suspect. Systemic illnesses such as @entity1252 and @entity1577 must be considered. @entity245 such as @entity788 may precipitate acute @entity788 through aberrant anatomic structures. Cancer must always be disproved. Not yet firmly established but worthy of thorough investigation are uncommon causes, such as the ingestion of certain drugs or combinations of drugs and @entity130 , either recent or past. @entity788 remains frightening for those with the disease and puzzling and frustrating for the medical @entity1 who treat it. A careful history and investigation in accordance with a systematic diagnostic plan that includes many disparate factors will lead to identification of the cause in the majority of @entity1 .
