Combined abdominal and perineal (anterior or posterior) approaches used in lower rectal cancer surgery have been based on similar anatomical and surgical features. The main aim of this manuscript is to evaluate the results of combined approaches performed for lower rectal cancer and to comment on surgical and anatomical features of the operations. Anatomical, surgical and clinical details of the combined abdominal and perineal approaches performed for lower rectal cancer were evaluated by reviewing published articles about this subject in English in PubMed, EMBASE, Cochrane library and other sources. Ten articles including case reports were found on combined abdominal and perineal approaches published between 2003 and 2015. There were 83 patients who had been operated by using combined approaches for lower rectal cancer surgical treatment in these series. While the circular resection margine positivity had not been reported in the cases; the mean Wexner continence score had been reported between 5 and 5.5. The most important dissatisfaction of these surgical methods has been reported as persistent perineal fistulas encountered 9.6% of the patients in average in the postoperative period. The APPEAR (Anterior Perineal Plane for Ultra Low Anterior Resection) procedure is the most known surgical procedure in which the combined abdominal and anterior perineal approach is used. Combined abdominal and perineal (anterior or posterior) approaches can be described as surgical procedures in which the sphincter-saving extrasphincteric dissection and proximal segmental sphincteric excision techniques are performed. As abordagens abdominais e perineais (anterior ou posterior) combinadas, utilizadas na cirurgia para o câncer retal baixo, têm se baseado em características anatômicas e cirúrgicas similares. O objetivo principal desse estudo é avaliar os resultados de abordagens combinadas realizadas em pacientes com câncer retal baixo e também comentar as características cirúrgicas e anatômicas das operações. Avaliamos os detalhes anatômicos, cirúrgicos e clínicos das abordagens abdominais e perineais combinadas para o câncer retal baixo por meio de uma revisão dos artigos publicados no idioma inglês sobre esse tópico em PubMed, EMBASE, Cochrane Library e outras fontes. Encontramos 10 artigos, inclusive relatos de casos, sobre abordagens abdominais e perineais combinadas publicados entre 2003 e 2015. Nessas séries, 83 pacientes no total tinham sido operados com o uso de ab
