| 1 | Endoscopic submucosal dissection of a rectal carcinoid tumor using grasping type scissors forceps显示文摘Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate. The shortcomings of this method are the inability to fix the knife to the target lesion, and compression of the lesion. These can lead to major complications such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping type scissors forceps (GSF), which can grasp and incise the targeted tissue using electrosurgical current. Colonoscopy on a 55-year-old woman revealed a 10-mm rectal submucosal nodule. The histological diagnosis of the specimen obtained by biopsy was carcinoid tumor. Endoscopic ultrasonography demonstrated a hypoechoic solid tumor limited to the submucosa without lymph node involvement. It was safely and accurately resected without unexpected incision by ESD using a GSF. No delayed hemorrhage or perforation occurred. Histological examination confirmed the carcinoid tumor was completely excised with negative resection margin. | Kazuya Akahoshi Yasuaki Motomura Masaru Kubokawa Noriaki Matsui Manami Oda Risa Okamoto Shingo Endo Naomi Higuchi Yumi Kashiwabara Masafumi Oya Hidefumi Akahane Haruo Akiba | 2009 | World Journal of Gastroenterology2009，15，17： | 4 |
| 2 | Conversion hepatectomy for hepatocellular carcinoma with main portal vein tumour thrombus after lenvatinib treatment: A case report显示文摘BACKGROUND Hepatocellular carcinoma(HCC)accompanied by portal vein tumour thrombus(PVTT)presents an aggressive disease course,worsening liver function reserve,and a high recurrence rate.Clinical practice guidelines recommend systemic therapy as the first-line option for HCC with portal invasion.However,to achieve longer survival in these patients,the treatment strategy should be concluded with removal of the tumour by locoregional therapy.We experienced a case of initially unresectable HCC with main PVTT converted to radical hepatectomy after lenvatinib treatment.CASE SUMMARY A 59-year-old male with chronic hepatitis C infection visited our clinic as a regular post-surgery follow-up.Contrast-enhanced abdominal computed tomography revealed a liver mass diffusely located at the lateral segment with a massive PVTT extending from the umbilical portion to the main and contralateral third-order portal branches.With the diagnosis of unresectable HCC with Vp4(main trunk/contralateral branch)PVTT,lenvatinib was started at 12 mg/d.The computed tomography taken 3 mo after starting lenvatinib showed regression of the PVTT,which had retreated to the contralateral first-order portal branch.He tolerated the full dose without major adverse effects.With cessation of lenvatinib for 7 d,radical left lobectomy and PVTT thrombectomy were conducted.The patient’s postoperative course was uneventful.Microscopically,the primary lesion showed fibrotic changes,with moderately to poorly differentiated tumour cells surrounded by granulation tissues in some areas.The majority of the PVTT showed necrosis.He was alive without recurrence for 8 mo.CONCLUSION This is the first case of HCC with Vp4 PVTT in which radical conversion hepatectomy was succeeded after lenvatinib treatment. | Kazuhiro Takahashi Jaejeong Kim Amane Takahashi Shinji Hashimoto Manami Doi Kinji Furuya Ryosuke Hashimoto Yohei Owada Koichi Ogawa Yusuke Ohara Yoshimasa Akashi Katsuji Hisakura Tsuyoshi Enomoto Osamu Shimomura Masayuki Noguchi Tatsuya Oda | 2021 | World Journal of Hepatology2021，13，3： | 1 |
