Purpose: To evaluate the usefulness of US-guided percutaneous gun biopsy through the left lobe of the liver with compression for the diagnosis of diffuse hepatic diseases and prevention of post-biopsy complications. Materials and Methods: In 35 patients with climical diffuse hepatic diseases, we performed US-guided percutaneous biopsy via the left lobe of the liver. After biopsy, we immediately applied an extrinsic hands-on compression maneuver at the biopsy site. The integrity of tissue architecture and numbers of portal triad visible in each specimen were histologically examined and post-biopsy complications were documented. Results: A histopathologic diagnosis could be made in all patients except one(97.1%). Microscopically, no significant crush artifact or fragmentation was demonstrated in these 34 patients. The average number of portal triad per specimen was about 4. 1. Although two patients complained of severe pain at the biopsy site, no serious post-biopsy complication was noted. Conclusion: US-guided percutaneous gun biopsy through the left lobe of the liver with compression appears to be an effective and safe procedure for the evaluation of diffuse hepatic diseases.

국내의 준공 연수 30년 이상 노후 교량이 2035년에는 전체 교량의 약 72%(약 21,000 개소)까지 차지할 것으로 예상되고 있다. 노후 교량의 증가가 예상됨에 따라 효율성 및 신뢰성을 갖춘 유지관리 기술에 대한 중요성 증가와 관련 기술의 개발이 기대되고 있다. 현재 교량의 안전점검은 인력기반으로 수행되고 있으며, 이는 객관성 및 효율성이 저하되고 점검 결과에 대한 신뢰성의 저하로 이어진다. 본 연구에서는 인력기반의 현 교량 안전점검의 한계를 개선하기 위해 영상기반의 콘크리트 균열 검출 알고리즘에 대한 연구를 수행하였다.

Vestibular neurectomy is known as an effective procedure in the management of intractable peripheral vertigo from Meniere's disease and other episodic peripheral vertigo disorders. Various approaches have been developed for selectively sectioning the vestibular nerve, in order to preserve hearing and avoid facial nerve injury. Vestibular neurectomy is performed in two patients with Meniere's disease to control intractable episodic vertigo through retrolabyrinthine approach. Vertigo was improved with preserving their hearing. We report the surgical technique and advantages of retrolabyrinthine vestibular neurectomy in the treatment of vertigo. Key words:Vestibular neurectomy;Meniere's disease;Retrolabyrinthine approach.
