Propensity score matching (PSM) was applied to balance baseline data among three groups. Each group contains 23 cases. Controlled group: specimens were extracted through abdominal incision. Pull\u2010out\u2010method group: specimens were extracted by transanal pull\u2010through coloanal anastomosis. Turn\u2010out\u2010method group: specimens were extracted by turn\u2010rectum\u2010out method. Clinical effects of the three extraction techniques were compared.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n There is no significant difference in surgery time, lymph nodes, blood loss, or incidence of postoperative complications in 1\u00a0week, hospital time, and financial cost (\n p<\/jats:italic>\n \u00a0>\u00a00.05, respectively). Tumor diameter and postoperative visual analogue scale (VAS) pain scores of controlled group were significantly higher than those of the pull\u2010out\u2010method group and turn\u2010out\u2010method group (\n p<\/jats:italic>\n \u00a0<\u00a00.05, respectively). Pull\u2010out\u2010method group and turn\u2010out\u2010method group had shorter time to ambulation and first flatus than the control group (\n p<\/jats:italic>\n \u00a0<\u00a00.05, respectively). No difference in prognosis was found among the three groups (\n p<\/jats:italic>\n \u00a0>\u00a00.05).\n <\/jats:p>\n <\/jats:sec>\n \n Limitations<\/jats:title>\n Small sample size.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Pull\u2010out\u2010method and turn\u2010out\u2010method are safe and available in laparoscopic anterior resection for rectal and low sigmoid colon cancer. Traditional abdominal incision strategy is suitable for larger specimens, whereas the pull\u2010out\u2010method strategy and turn\u2010rectum\u2010out strategy cause less trauma and have quicker
