Abstract：
BACKGROUND: Treatment of postoperative anastomotic stenosis for colorectal cancer is often challenging, especially for patients who do not respond well to endoscopy. In cases where patients have undergone an enterostomy, the stenosis can be easily resolved through magnetic compression. However, common magnetic compression techniques cannot be performed on those without enterostomy. We designed a novel Y-Z deformable magnetic ring (Y-Z DMR) and successfully applied it to a patient with a stenosis rectal anastomosis and without enterostomy after rectal cancer surgery.
METHODS: We here report the case of a 57-year-old woman who had undergone a laparoscopic radical rectum resection (Dixon) for rectal cancer. However, she started facing difficulty in defecation 6 months after surgery. Her colonoscopy indicated stenosis of the rectal anastomosis. Endoscopic balloon dilation was performed six times on her. However, the stenosis still showed a trend of gradual aggravation. Because the patient did not undergo an enterostomy, the conventional endoscopic magnetic compression technique could not be performed. Hence, we implemented a Y-Z DMR implemented through the anus under single channel. The magnetic ring fell off nine days after the operation and the rectal stenosis was relieved. The patient was followed up for six months and reported good defecation.
CONCLUSIONS: The Y-Z DMR deformable magnetic ring is an excellent treatment strategy for patients with rectal stenosis and without enterostomy.

摘要：
背景：结直肠癌术后吻合口狭窄的治疗通常具有挑战性，尤其是对内窥镜检查反应不佳的患者。如果患者接受了肠造口术，狭窄可以很容易地解决通过磁压缩。然而,普通的磁压缩技术不能对那些没有肠造口术的人进行。我们设计了一种新型的Y-Z可变形磁环（Y-ZDMR），并成功地将其应用于直肠癌手术后直肠吻合狭窄且没有肠造口的患者。
方法：我们在此报告一例57岁女性因直肠癌行腹腔镜直肠癌根治术（Dixon）。然而,手术后6个月，她开始面临排便困难。她的结肠镜检查显示直肠吻合口狭窄。对她进行了六次内窥镜球囊扩张术。然而,狭窄仍有逐渐加重的趋势。因为病人没有接受肠造口术，传统的内窥镜磁压缩技术无法执行。因此，我们在单通道下通过肛门实施了Y-ZDMR。术后9天磁性环脱落，直肠狭窄缓解。患者随访6个月，报告排便良好。
结论：Y-ZDMR可变形磁环是直肠狭窄且无肠造口患者的一种极好的治疗策略。
