M\u00e9todos: estudo retrospectivo de 56 pacientes submetidos \u00e0 amputa\u00e7\u00e3o abdominoperineal de reto por neoplasias de reto distal e de canal anal, tratados no Hospital Central da Santa Casa de Miseric\u00f3rdia de S\u00e3o Paulo entre 2008 e 2017.  Resultados: a m\u00e9dia de idade dos pacientes foi de 63,08 anos, sendo 48,2% deles mulheres e 51,8%, homens. Adenocarcinoma foi o tipo histol\u00f3gico em 94,6% dos casos e carcinoma espinocelular em 5,4%. A posi\u00e7\u00e3o de Lloyd-Davies foi a adotada em 66,1% das cirurgias e a posi\u00e7\u00e3o ventral em 33,9%. No momento da cirurgia quatro pacientes apresentavam met\u00e1stases sincr\u00f4nicas: hep\u00e1tica (um caso), pulmonar (um caso) e hep\u00e1tica e pulmonar simult\u00e2neas (dois casos). Tratamento neoadjuvante foi realizado em 85,7% dos pacientes. Complica\u00e7\u00f5es p\u00f3s-operat\u00f3rias tardias ocorreram em 13 pacientes operados na posi\u00e7\u00e3o cl\u00e1ssica e em um paciente operado em dec\u00fabito ventral. O tempo de sobrevida global para o grupo operado na posi\u00e7\u00e3o cl\u00e1ssica foi, em m\u00e9dia, de 45,7 meses, enquanto que no grupo operado em dec\u00fabito ventral foi de 15,5 meses.  Conclus\u00e3o: o grupo da posi\u00e7\u00e3o ventral apresentou menor necessidade de infus\u00e3o de volume intravenoso intraoperat\u00f3rio e menos complica\u00e7\u00f5es p\u00f3s-cir\u00fargicas tardias, enquanto que o grupo Lloyd-Davies obteve melhores tempos cir\u00fargicos e anest\u00e9sicos. Recidiva, tempo livre de doen\u00e7a e sobrevida global devem ser avaliados em um tempo maior de seguimento.<\/jats:p>","DOI":"10.1590\/0100-6991e-20181643","type":"journal-article","created":{"date-parts":[[2018,10,19]],"date-time":"2018-10-19T15:10:46Z","timestamp":1539961846000},"source":"Crossref","is-referenced-by-count":0,"title":["Estudo comparativo entre a amputa\u00e7\u00e3o de reto na posi\u00e7\u00e3o cl\u00e1ssica de Lloyd-Davies e em dec\u00fabito ventral."],"prefix":"10.1590","volume":"45","author":[{"given":"Rodrigo Barbosa","family":"Novais","sequence":"first","affiliation":[{"name":"Santa Casa de Miseric\u00f3rdia,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alex Albuquerque Lins","family":"Barbosa","sequence":"additional","affiliation":[{"name":"Santa Casa de Miseric\u00f3rdia,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Priscila Marques","family":"Intelizano","sequence":"additional","affiliation":[{"name":"Santa Casa de Miseric\u00f3rdia,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fang Chia","family":"Bin","sequence":"additional","affiliation":[{"name":"Santa Casa de Miseric\u00f3rdia,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karina Dagre Magri","family":"Castro","sequence":"additional","affiliation":[{"name":"Santa Casa de Miseric\u00f3rdia,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernanda Bellotti","family":"Formiga","sequence":"additional","affiliation":[{"name":"Santa Casa de Miseric\u00f3rdia,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thiago Silveira","family":"Manzione","sequence":"additional","affiliation":[{"name":"Santa Casa de Miseric\u00f3rdia,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cau\u00ea Fedrigo Loyola","family":"Batista","sequence":"additional","affiliation":[{"name":"Faculdade de Medicina do ABC,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2018,10,18]]},"reference":[{"key":"ref1","series-title":"Coordena\u00e7\u00e3o de Preven\u00e7\u00e3o e Vigil\u00e2ncia Estimativa 2014: Incid\u00eancia de C\u00e2ncer no Brasil","year":"2014"},{"key":"ref2","series-title":"Pathology and Genetics of Tumours of the Digestive System","author":"Hamilton SR"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"1128","DOI":"10.1002\/cncr.22010","article-title":"A population-based study of colorectal cancer histology in the United States, 1998-2001","volume":"107","author":"Stewart SL","year":"2006","journal-title":"Cancer"},{"issue":"3","key":"ref4","doi-asserted-by":"crossref","first-page":"483","DOI":"10.1007\/s10350-004-0822-6","article-title":"Ten-year historic cohort of quality of life and sexuality in patients with rectal cancer","volume":"48","author":"Schmidt CE","year":"2005","journal-title":"Dis Colon Rectum"},{"issue":"2","key":"ref5","first-page":"103","article-title":"Amputa\u00e7\u00e3o abdominoperineal: uma cirurgia fora de moda? -
