Objective To explore the feasibility of single⁃incision laparoscopic sigmoid colon vaginoplasty in women with congenital absence of va⁃gina. Methods Clinical data of thirty⁃two patients with congenital absence of vagina admitted in Shengjing Hospital of China Medical University be⁃tween January 2008 and June 2014 was retrospectively analyzed. Nineteen patients underwent laparoscopic assisted sigmoid colon vaginoplasty,and thirteen paitiens underwent single⁃incision laparoscopic sigmoid colon vaginoplasty. The operation time,intraoperative blood loss,evacuation time and follow up were compared between the two groups. Results In the group of single⁃incision laparoscopic sigmoid colon vaginoplasty,the opera⁃tion time was shorter and intraoperative blood loss was less. There was no difference between two groups in evacuation time. There was no infection or leakage of anastomotic stoma of sigmoid colon,and no postoperative stenosis of the neovagina and its length was satisfied. Patients were satisfied with the quality of sexual life after the surgery. Patients underwent single⁃incision laparoscopic sigmoid colon vaginoplasty were all satisfied with the ap⁃pearance of abdomen. Conclusion The single⁃incision laparoscopic sigmoid colon vaginoplasty can simplify the procedure of intestinal anastomo⁃sis,shorten the operation time,and reduce the intraoperative blood loss. Consequently,the single⁃incision laparoscopic sigmoid colon vaginoplasty is effective and safe.%目的：探讨单孔腹腔镜乙状结肠代阴道成形术治疗先天性无阴道的可行性。方法回顾性分析2008年1月至2014年6月中国医科大学附属盛京医院收治的32例先天性无阴道患者的临床资料，其中，行腹腔镜辅助的乙状结肠代阴道成形术19例，行单孔腹腔镜乙状结肠代阴道成形术13例。比较2组的手术时间、术中出血量、术后排气时间及术后随访情况。结果与腹腔镜辅助的乙状结肠代阴道成形术相比，单孔腹腔镜乙状结肠代阴道成形术的手术时间较短，术中出血量较少。2组术后排气时间无明显差异。乙状结肠吻合口无感染及肠瘘发生。形成的人工阴道无狭窄，且长度满意。术后随访患者对性生活质量满意，单孔腹腔镜手术患者对腹部的外观更为满意。结论单孔腹腔镜乙状结肠代阴道成形术肠吻合过程操作简便，且手术时间短、出血量少，治疗先天性无阴道安全有效。
