Radiation dermatitis can develop after fluoroscopy-guided interventional procedures. Cases of fluoroscopy-induced radiation dermatitis have been reported since 1996, mostly documented in the fields of radiology, cardiology and dermatology. Since diagnosis and treatment of fluoroscopy-induced radiation dermatitis can be difficult, high grade of suspicion is required. The extent of this reaction is determined by radiation dose, duration of exposure, type of procedure, and host factors and can be aggravated by concomitant use of photosensitizers. Follow-up is important after long and complicated procedures and efforts to minimize radiation exposure time will be necessary to prevent radiation dermatitis. Herein, we report a case of a 58-year-old man with hepatocellular carcinoma presenting with subacute radiation dermatitis after prolonged fluoroscopic exposure during transarterial chemoembolization and chemoport insertion. Physicians should be aware that fluoroscopy is a potential cause of radiation dermatitis. (Korean J Gastroenterol 2016;67:112-115)

Enterolith is a rare complication of Billroth II gastrectomy. Most enterolith cases have been reported in association with diverticula, tuberculosis, and Crohn’s disease. We report the case of a huge enterolith that developed in the duodenal stump following common bile duct obstruction and cholangitis, necessitating surgery. The enterolith was clearly visible on the abdominal computed tomography. It was removed through a duodenotomy. The surgery was successful without any significant complications.
