Transanal endoscopic microsurgery (TEM) is widely used for the excision of both benign and malignant rectal tumours. It is relatively expensive and can be a challenging technique. A recent development in laparoscopic surgery is the single-port technique (single-incision laparoscopic surgery, SILS). The SILS port is a flexible multichannel port for transumbilical laparoscopic surgery. Even though not developed for transanal use the port could be ideal because of its shape and texture.
12 patients underwent transanal resection using an SILS port and normal laparoscopic instruments.
10 out of 12 patients were treated successfully with the SILS port. Two polyps were resected using an open transanal technique because the distance between the SILS port and the polyp was too small. The average operative time was 55 min (range 40-80 min). All patients could be discharged on the first postoperative day. There were no major complications.
Our current data show that transanal surgery using a single port is a relatively easy procedure with operative times comparable to TEM. More surgeons will therefore be able to perform transanal endoscopic surgery.
经肛门内镜微创手术（TEM）广泛应用于良性和恶性直肠肿瘤的切除。该手术相对昂贵，且具有一定难度。腹腔镜手术的一项新技术是单孔技术（单孔腹腔镜手术，SILS）。SILS 端口是一种用于经脐腹腔镜手术的灵活多通道端口。尽管该端口并非专门为经肛门使用而设计，但由于其形状和质地，它可能是理想的选择。
12 名患者使用 SILS 端口和普通腹腔镜器械进行经肛门切除术。
12 名患者中有 10 名成功地接受了 SILS 端口治疗。由于 SILS 端口和息肉之间的距离太小，2 个息肉采用开放式经肛门技术切除。平均手术时间为 55 分钟（范围 40-80 分钟）。所有患者均于术后第 1 天出院。无重大并发症。
我们目前的数据表明，使用单孔的经肛门手术是一种相对简单的手术，手术时间与 TEM 相当。因此，更多的外科医生将能够进行经肛门内镜手术。
