A Case of Successful Endoscopic Clipping for Iatrogenic Colon Perforation Induced by Peritoneal Catheter Insertion / 대한소화기학회지

Advanced cancer patients with refractory ascites often do not respond to conventional treatments including dietary sodium restriction, diuretics, and repeated large volume paracentesis. In these patients, continuous peritoneal drainage by an indwelling catheter may be an effective option for managing refractory ascites with a relative low complication rate. Peritoneal catheter-induced complications include hypotension, hematoma, leakage, cellulitis, peritonitis, and bowel perforation. Although bowel perforation is a very rare complication, it can become disastrous and necessitates emergency surgical treatment. Herein, we report a case of a 57-year-old male with refractory ascites due to advanced liver cancer who experienced iatrogenic colonic perforation after peritoneal drainage catheter insertion and was treated successfully with endoscopic clipping.

A Case of Occupational Hypersensitivity Pneumonitis Associated with Trichloroethylene / 결핵및호흡기질환

Trichloroethylene (TCE) is a toxic chemical commonly used as a degreasing agent, and it is usually found in a colorless or blue liquid form. TCE has a sweet, chloroform-like odor, and this volatile chlorinated organic chemical can cause toxic hepatitis, neurophysiological disorders, skin disorders, and hypersensitivity syndromes. However, the hypersensitivity pneumonitis (HP) attributed to TCE has rarely been reported. We hereby describe a case of HP associated with TCE in a 29-year-old man who was employed as a lead welder at a computer repair center. He was installing the capacitors on computer chip boards and had been wiped down with TCE. He was admitted to our hospital with complaints of dry coughs, night sweats, and weight losses for the past two months. HP due to TCE exposure was being suspected due to his occupational history, and the results of a video-associated thoracoscopic biopsy confirmed the suspicions. Symptoms have resolved after the steroid pulse therapy and his occupational change. TCE should be taken into consideration as a potential trigger of HP. Early recognition and avoidance of the TCE exposure in the future is important for the treatment of TCE induced HP.
