狭窄を来す大腸疾患─病理診断の立場から

Pathological Diagnosis of Colorectal Diseases with Stenosis

要旨●大腸狭窄の原因疾患は，病理学総論の立場から，腫瘍性と非腫瘍性に大別される．これらの鑑別診断には，病理形態学的所見の他，さまざまな臨床情報が必要である．したがって，臨床医と病理医は緊密な連携および十分な意思疎通・意見交換が不可欠である．

　The causes of intestinal stenosis are classified into neoplastic and non-neoplastic based on their general pathology. Not only pathological findings but also various clinical data（e.g., history, physical findings, endoscopic appearance, and location of the lesion）are essential for accurate diagnosis. Therefore, close cooperation and communication between the clinician and pathologist are essential to enhance the accuracy and quality of the differential diagnoses.
