We have developed an anastomosis technique for resection of the distal colon based on the principle of submucosal layer apposition. The anastomosis apparatus consists of two rings of Ertalyte (polyester-polyethyleneterephtalate) containing two magnetic rings of polymer bonded rare earth cobalt. For low anastomoses we developed a magnetic ring holder, protecting cap and hexagonal connecting rod. The working principle is based on progressive compression leading to necrosis of the intermediate mucosal and submucosal layers by increasing magnetic force while bowel healing takes place. After 7 to 17 days the magnets cut through and are propelled by peristalis out of the anastomotic region. From our initial series of five patients we performed three sigmoid resections and two low anterior resections. There were no postoperative complications. Sigmoidoscopic and radiological investigations two weeks postoperatively, showed no evidence of leakage or anastomotic narrowing. The technique and the special advantages of the apparatus are discussed.
我们基于黏膜下层对合原理开发了一种用于远端结肠切除的吻合技术。吻合装置由两个埃塔利特（聚酯 - 聚对苯二甲酸乙二酯）环组成，其中包含两个聚合物粘结稀土钴磁环。对于低位吻合，我们开发了磁环固定器、保护帽和六角形连杆。其工作原理是基于渐进性压迫，通过增加磁力导致中间黏膜和黏膜下层坏死，同时肠道进行愈合。7至17天后，磁体穿透并通过蠕动被推进出吻合区域。在我们最初的5例患者系列中，我们进行了3例乙状结肠切除术和2例低位前切除术。没有术后并发症。术后两周的乙状结肠镜和放射学检查显示没有渗漏或吻合口狭窄的迹象。本文讨论了该技术及该装置的特殊优势。
