Removal of a large rectal polyp with endoscopic submucosal dissection-trans-anal rectoscopic assisted minimally invasive surgery hybrid technique:A case report

BACKGROUND Endoscopic submucosal dissection(ESD)can be used for the en-bloc removal of superficial rectal lesions;however,the lack of a traction system makes the procedure long and difficult in the presence of extensive lesions.CASE SUMMARY A large polyp occupying 2/3 of the rectal circumference and extending 5 cm in length was removed by ESD with the help of laparoscopic forceps introduced via trans-anal rectoscopic assisted minimally invasive surgery,a disposable platform designed to aid in transanal minimally invasive surgery.Traction of the polyp by forceps during the operation was dynamic,and applied at various points and in various directions.The polyp was removed en-bloc without complications in 1 h and 55 min.A sigmoidoscopy performed 50 d later showed normal healing without polyp recurrence.CONCLUSION The technique presented here could overcome the issues caused by lack of traction during ESD for rectal lesions.

127例良性直肠息肉的治疗

目的 :探讨直肠息肉的治疗方法。方法 :回顾性分析近 5年来诊治的直肠息肉 1 2 7例。结果 :1 2 7例直肠息肉中 ,直肠管状腺瘤 6 9例 ,绒毛状腺瘤 2 8例 ,炎性息肉 2 5例 ,幼年性息肉 5例 ;伴结肠癌 1 0例 ,伴直肠癌 8例 ;经肠镜活检钳钳除4 1例 ,经肠镜电切 4 5例 ,手术切除 33例 ,与伴随直肠癌一并切除 6例 ,未处理 2例。结论 :6 7 72 %的直肠息肉可经肠镜治疗 ,但广基及 2cm以上的腺瘤多数需手术治疗 ,手术根据肿瘤位置可选用经直肠后或括约肌入路、经腹入路或经肛门入路 ,与传统经肛门或剖腹手术相比 ,经直肠后或括约肌入路显露更好 ,且切除更准确、并发症率低和住院时间短 ,是切除直肠腺瘤的安全。
