Prospect of Endoscopic Mucosal Resection for Early Gastric Cancer: Our Devices in Insulated‐Tip Electrosurgical Knife Method

In Kobe University Hospital, a new method for endoscopic mucosal resection (EMR) using insulated‐tip electrosurgical knife (IT‐EMR) for early gastric cancer (EGC) was introduced from November 2001. To achieve an effective and safe IT‐EMR procedure, we use a high‐frequency surgical unit for cutting and coagulation (ERBOTOM ICC 200) with automatically controlled cutting mode (ENDOCUT). In this study, we show not only our results of IT‐EMR for EGC in comparison with those of the conventional strip biopsy method, but also the optimal conditions for the apparatus of a high‐frequency surgical unit to prevent complications such as bleeding and perforation.     

氩氦刀的原理与应用中的优势和不足

NEW DEVICE TO PERFORM COAGULATION AND IRRIGATION SIMULTANEOUSLY DURING ENDOSCOPIC SUBMUCOSAL DISSECTION USING AN INSULATION‐TIPPED ELECTROSURGICAL KNIFE

Background: Although bleeding is an unavoidable complication of endoscopic submucosal dissection (ESD), endoscopic hemostasis using an insulation‐tipped electrosurgical knife (IT) knife is impossible because an insulator is mounted at the tip of the knife. We have developed a new type of hood which could perform both coagulation and irrigation simultaneously. Methods: Our new device was fabricated by drilling a side hole in the cap portion of a conventional transparent hood followed by attaching a machined papillotomy knife to the exterior surface of the hole. Results: Our new hood was useful for hemorrhage during ESD using IT knife. Conclusions: With this method, endoscopic hemostasis using IT knife is easy, as hemostatic procedure can be performed under irrigation and coagulation using conventional endoscopy.     

小针刀辅助自体脂肪颗粒移植在面部除皱及凹陷充填中的应用

目的探讨小针刀辅助自体脂肪颗粒注射除去额部、眉间、鼻唇沟等部位皱纹及充填面部凹陷的效果。方法利用自制小针刀,离断真皮与其下方的"纤维粘连",然后用自体脂肪颗粒注射除皱和充填凹陷部位。结果本组共68例。修复面积最大约10cm×8cm,最小约1.5cm×0.5cm。随访45例,随访时间3～18个月,效果满意或基本满意。结论小针刀辅助自体脂肪移植具有操作简单、快捷、价廉、安全、无排异、不留瘢痕、术后恢复快等优点,患者易于接受,是除去额部、眉间、鼻唇沟等部位皱纹及填充面部凹陷的有效方法。     

TECHNIQUES AND PITFALLS OF ENDOSCOPIC SUBMUCOSAL DISSECTION FOR COLORECTAL TUMORS

Endoscopic submucosal dissection (ESD) for colorectal tumors is steadily being developed. Safety and standardization of ESD for colorectal tumors have not been yet established because of the technical difficulties and the unsuitable anatomical characteristics of the colon and rectum. The authors mainly use a Flex knife for mucosal incision and a Hook knife for submucosal dissection to perform ESD safely. Skillful colonoscopic control, selection of scope, distal attachment tip hood, adequate high‐frequency generator and correct approach strategy should all be considered for safe performance of ESD. However, the incidence of indicative lesions is rare because the majority of colorectal tumors are adenomatous large laterally spreading tumors, which can be cured by intentional endoscopic piecemeal resection. At present, ESD for colorectal tumors should be performed only at central facilities that have expert colonoscopists. With the development of new devices and associated techniques, technical standardization of ESD for colorectal tumors is expected in the near future.     

伽玛刀治疗颅底良性脑膜瘤临床研究

目的探讨伽玛刀放射外科治疗良性颅底脑膜瘤中长期疗效和不良反应。方法选取了1998-2003年治疗的获得完全随访资料的颅底脑膜瘤患者166例,全组患者肿瘤体积0.42- 43.4cm3,平均(7.2±3.9)cm3,给予周边剂量平均(12.4±2.6)Gy,中心剂量平均(27.9±5.9)Gy,其中12例患者采用肿瘤体积分割二阶段治疗。对治疗前后的影像学改变、KPS评分和神经功能缺损评估。结果平均随访期为(55.4±18.2)个月(36-96个月)。总体控制率为95.2%(158/166);KPS评分得到显著提高,神经症状总体满意率为94.5%(157/166),主要副作用是放射性脑水肿11例(6.6%),有5例(3%)患者出现新的神经缺损。结论伽玛刀放射外科可以作为有手术禁忌或拒绝手术治疗体积较小脑膜瘤患者的首选性治疗,也可以作为颅底较大脑膜瘤开颅术后的辅助性治疗,能够较长期控制肿瘤复发,提高或保持患者的生存质量。     

Is endoscopic one‐piece mucosal resection essential for early gastric cancer?

Background: Endoscopic mucosal resection (EMR) is widely accepted as a minimally invasive treatment for early gastric cancer (EGC) in Japan. However, the criteria for EMR must be strictly adhered to otherwise patients will miss the chance for additional therapy. We assess the important factor in expanding the indication of EMR. Methods: We investigated 1101 EGCs that had been resected by EMR at the National Cancer Center Hospital (NCCH), Tokyo, Japan, according to the indication recommended by Japanese Gastric Cancer Association (JGCA) and the expanded indication proposed by NCCH. Curability and local recurrence of the EMRs were assessed related to the applied indication and the number of resected specimens. Results: The recurrence rate of non‐evaluable resection was higher than that of evaluable resection (P < 0.0001). Eighty‐three lesions among 772 lesions in the JGCA group were non‐evaluable. Thirty‐seven leisons among 329 lesions in the NCCH group were non‐evaluable. There was no difference in the rate of non‐evaluable resection between JGCA and NCCH groups (P = 0.8329). However, the rate of curative resection was lower in the NCCH group than in the JGCA group (P = 0.0009). In piecemeal resection, there was no difference in the rate of non‐evaluable resection between JGCA and NCCH groups (P = 0.0527). In one‐piece resection, the rate of non‐evaluable resection was lower in the NCCH group than the JGCA group (P = 0.0137). Conclusion: Based on our series of cases, we propose one‐piece resection as a gold standard for EMR because it enables accurate histological evaluation, even in the EMR, according to the expanded indication.
