经导光肛门自动牵开镜手术治疗直肠肿瘤51例

Surgical Therapy via Light-guided Anodilator-rectoscope in the Treatment of Rectal Tumors：Analysis of 51 Cases

为降低手术治疗直肠肿瘤的创伤程度，选择距肛缘10cm以内的51例直肠良性肿瘤经导光肛门自动牵开镜微创切除。结果显示，16例术后肛门轻度疼痛，10例出现尿潴留。7例出现不完全性肛门失禁。术后病理示50例为直肠腺瘤（管状腺瘤27例，绒毛状腺瘤15例，管状绒毛状腺瘤8例）；1例病灶基底部发现有癌细胞，为高分化直肠腺癌。术后随访6个月至3年，无复发病例，肛门功能正常。结果表明，于导光肛门自动牵开镜下治疗良性直肠腺瘤和早期直肠癌具有安全、有效、手术操作方便快捷、创伤小、术后复发率低等优点，近期疗效满意。

The objective of the study was to lessen the surgical wound in the treatment of rectal tumors. Fifty one patients with benign rectal tumors which located within 10era from the anal edge, underwent microtraumatic surgical resection via light-guided anodilator-rectoscope （LGAR）. As results,slight postoperative pain was noticed in 16 cases,urine retention in 10 cases,and incomplete anal incontinence in 7 cases. Of the 51 cases,rectal adenoma was found in 50 cases（27 tubular adenoma, 15 villous adenoma,8 tubular villous adenoma） and rectal carcinomatous cell was found in basal of tumor in 1 case, which was well differ- entiated rectal adenocarcinoma. No recurrence was found and anal function was normal in all the cases during follow up of 6 36 months. It is concluded that surgical therapy via light-guided anodilator-rectoscope in the treatment of benign rectal tumors and early rectal carcinoma is safe,effective and better in therapeutic results among other strong points（simpler in operation,less in surgical wound,lower recurrence）.
