Core Tip

Core tip: This case demonstrated that detailed inquiry of medical history and effective auxiliary examinations are important for accurate diagnosis. Endoscopic balloon dilatation and metal stent implantation played key roles in the differential diagnosis and bridge treatment of benign colon stenosis. Finally, adequate awareness of drug-induced sigmoid stenosis is very important for avoiding misdiagnosis and mistreatment.
