ABSTRACT

INTRODUCTION:

Familial adenomatous polyposis (FAP), an autosomal dominant disease characterized by development of numerous adenomatous polyps in the colon and rectum, is caused by germline mutations in the Adenomatous Polyposis Coli (APC) gene.

METHODS:

To determine the surgical morbidity in patients with classical familial adenomatous polyposis and determine the incidence of metachronous colorectal cancer (CRC) in those undergoing total colectomy (TC) with ileorectal anastomosis or restorative total proctocolectomy (TPC) and ileal pouch anal anastomosis. We analyzed patients with familial adenomatous polyposis who received treatment and regular follow-up at the A.C. Camargo Cancer Center from 1994 to 2013.

RESULTS:

Operative complications occurred in 22 patients (34.3%), 16 (25%) being early complications and 8 (12.5%) late complications. No mortality occurred as a result of postoperative complications. The incidence of metachronous rectal cancer after total proctocolectomy was 2.3% and after total colectomy 18.18% (p = 0.044).

CONCLUSIONS:

In order to provide better quality of life for individuals with familial adenomatous polyposis, total colectomy is commonly offered, as this simple technique is traditionally associated with lower rates of postoperative complications and better functional outcomes. However, it has become a less attractive technique in patients with familial adenomatous polyposis in its classical or diffuse form, since it has a significantly higher probability of metachronous rectal cancer.

RESUMO

INTRODUÇÃO:

Polipose adenomatosa familiar (PAF), uma doença autossômica dominante caracterizada pela formação de numerosos pólipos adenomatosos no cólon e reto, é causada por mutações da linha germinativa no gene da polipose adenomatosa do cólon (PAC).

MÉTODOS:

Para determinar a morbidade cirúrgica em pacientes com PAF clássica e determinar a incidência de câncer colorretal (CCR) metacrônico naqueles pacientes submetidos à colectomia total (CT) com anastomose íleo-retal ou submetidos à proctocolectomia restaurativa (PCT) e anastomose bolsa ileal-anal, foram analisados pacientes com PAF que foram tratados e tiveram acompanhamento periódico no A. C. Camargo Cancer Center de 1994 até 2013.

RESULTADOS:

Ocorreram complicações cirúrgicas em 22 pacientes (34,3%); 16 (25%) tiveram complicações precoces e 8 (12,5%) complicações tardias. Não houve mortes como resultado de complicações pós-operatórias. A incidência de câncer de reto metacrônico após PCT foi de 2,3% e após CT foi de 18,18% (p = 0,044).

CONCLUSÕES:

A fim de proporcionar melhor qualidade de vida para os pacientes com PAF, CT é comumente oferecida, pois esta técnica simples está tradicionalmente associada com menores percentuais de complicações pós-operatórias e melhores resultados funcionais. No entanto, CT se tornou uma técnica menos atraente em pacientes com PAF em sua forma clássica ou difusa, uma vez que traz consigo uma probabilidade significativamente maior de câncer retal metacrônico.
