An association between clinical, diet profile, and microscopic features in colorectal lesions was observed, with a progressive change in the microenvironment during adenoma-CRC sequence.
OBJETIVOO objetivo deste trabalho é relatar um caso de Melanoma de Canal Anal atendido e tratado no Serviço de Coloproctologia do Vitória Apart Hospital -VAH, em janeiro de 2009, demonstrando a possibilidade deste tipo de tumor simular uma doença hemorroidária do terceiro para quarto grau.
CONCLUSÃOMelanoma anorretal é uma entidade pouco freqüente e com prognóstico bastante reservado. A localização no canal anal da doença pode simular doenças anorretais inclusive com prolapso da lesão como foi observado neste caso. O diagnóstico e o tratamento cirúrgico realizados de forma precoce podem trazer uma maior sobrevida ao paciente, sendo importante que os pacientes sejam sempre bem examinados pelo proctologista.
INTRODUÇÃOO Melanoma Anorretal é um tumor maligno e muito agressivo, responsável por 4% de todas as doenças malignas da região anal 14 . Embora seja incomum, a região anal é o terceiro local mais acometido pelo melanoma, depois do tipo cutâneo e ocular 18 . O termo
Introduction The surgical treatment of anorectal cancer is considered a challenging topic. Colostomy, temporary or permanent, can be a serious limiting factor with respect to the quality of life of cancer patients. Our goal is to study the clinical and surgical experience in patients with anorectal cancer, in whom we proceeded to abdominoperineal resection with a perineal colostomy at the anterior border of the incision resulting from the amputation of the rectum.
Methods The medical records of patients undergoing abdominoperineal resection with perineal colostomy from January 1st, 1998 to July 1st, 2012 were analyzed retrospectively.
Results Twenty-seven patients were studied; 15 (55.56%) were male and 12 (44.44%) females, with a mean age of 56.3 years. The average length of hospital stay was 7.4 days. Complications included four (14.8%) prolapses of the perineal colostomy, which were surgically treated after the sixth month postoperatively, two (7.4%) partial suture dehiscences of the perineal colostomy, treated with hyperbaric oxygen therapy, two (7.4%) stenoses of the perineal colostomy, treated with dilation, two (7.4%) incisional hernias and one (3.7%) urinary incontinence.
Conclusion The perineal colostomy is a relatively new proposition, with acceptable morbidity rates. We understand that the perineal colostomy dismisses the use of a collection device, leaves no odor and allows the periodic application of enemas for colon cleansing, which prevents stoma incontinence. Another advantage is to enable the patient's return to a good social and work interaction; thus, it will be possible his (her) reintroduction into society.
