Directory of Open Access Journals Sweden. Identification of risk factors for requiring transfusions during surgery for colorectal cancer may lead to preventive actions or alternative measures, towards decreasing the use of blood components in these procedures, and also rationalization of resources use in hemotherapy services.
To recognize significant risk factors for requiring intraoperative blood transfusion in colorectal cancer surgical procedures. Univariate analyses were performed using Fisher’s exact test or the chi-squared test for dichotomous variables and Student’s t test for continuous variables, followed by multivariate analysis using multiple logistic regression. To compare histopathological variables and staging in colorectal adenocarcinoma cases with CEA and CA in peripheral and mesenteric blood.
In individuals underwent surgery for colorectal cancer, CEA and CA were analyzed and compared to mesenteric and peripheral blood and correlated with macroscopic tumor’s morphology and size, degree of cell differentiation, venous, neural and lymphatic involvement and TNM classification.

Evaluate the relationship of two proteins, which take part in the coloztomia mechanism of cell adhesion, with the cell differentiation degree and TNM staging I and IV in colorectal cancer. One-hundred patients 54 men and 46 women, who have received treatment for colorectal cancer, stages I 44 and IV 56, have been studied. Histological cuts of tumor tissue were examined by the immunohistochemical technique. Hemangioma colorretal Colon rectal hemangioma.
The colon and rectum hemangioma is a rare benign vascular lesion, with clinical features usually between 5 and 25 years of age. It is included in the differential diagnose of the lower digestive bleeding causes, and has been frequently misdiagnosed with other more common entities, like hemorrhoids and bowel inflammatory disease. We report a case of a 17 years old girl who was admitted at the Coloproctology Service of the Academic Hospital – HUUFMA, in September colosstomia, with coloxtomia and intermittent rectal bleeding since uartman.
Laboratorial findings included laboratorial exams, GI endoscopy, colonoscopy and arteriography of mesenteric and. Os FCA foram selecionados. Foram observados 20 FCA, sendo que 13 destes focos localizavam-se nas proximidades do tumor. The meaning of being a man with intestinal stoma due to colorectal cancer: Robotic assisted colorrectal surgery.
The development of minimally invasive surgical techniques represents an important aspect of modern surgical research. Robot-assisted minimally invasive colorectal surgery represents a way of assisting laparoscopic colorectal procedures.
Robotic technology overcomes some of these limitations by successfully providing intuitive motion and enhanced precision and accuracy, in an environment that is much more ergonomic. A restrict number of surgeons in specialized centers around the world have been applying robotics.
In this review, current evidence about different technologies and its place in colorectal surgery is evaluated. The feasibility of performing robot-assisted colorectal operations has been demonstrated though case.
Full Text Available We colotomia a case of primary malignant pylorus neoplasia, emphasizing its rarity, the difficulty of diagnosis and the importance of an adequate prepare before the endoscopic procedure.
Literature shows that tumors compromising the first, third and fourth segments of duodenum are rare, especially those of the pyloric area, representing only 0. The most common symptoms are weight loss, nausea, vomiting, abdominal pain, abdominal mass, sudden changes in intestinal habits and iron deficiency anemia secondary to chronic intestinal hemorrhage. We report a case of a seventy-one year-old male referring early satiety, epigastric pain, retrosternal burning and dyspepsia, with unspecific results in complementary exams, since complete gastric emptying was not achieved.
As symptoms worsened, the patient was submitted to laparotomy, with identification of gastric dilation and severe pyloric stenosis, macroscopically suggesting malignancy. The chosen procedure was a subtotal gastrectomy. Adjuvant radiotherapy and chemotherapy were not used. The patient is been followed-up without tumor recurrence so far. Laparoscopic gastrectomy for gastric adenocarcinoma: Resultados a largo plazo.
Full Text Available Background: Patients with adenocarcinoma of the cardia were excluded. Mean age of patients was 68 years range, years. Average survival time for 10 non-resected patients was 4. Average survival rate for all 14 palliatively resected patients was 6.
Laparoscopic gastrectomy hart,an locally advanced cancers is equivalent to laparotomy as far as long-term oncological results are concerned.
Development of studies in molecular biology over the last decades has contributed for better knowledge about colorectal carcinogenesis. An important landmark in this process was the identification of a protein with effect on vascular permeability eventually named as vascular endothelial growth factor VEGF, which seems to be essential for the angiogenesis activation of tumor development.
The aim of this study was to assess the VEGF expression hqrtman correlate to tumor staging in colorectal cancer. Surgical specimens from 56 colorectal cancer patients.
Laparoscopic left lateral segmentectomy for metachronic metastases of small intestine adenocarcinoma: Full Text Available Hepatectomy has been the standard treatment for metachronic metastases of non-colorectal NCR origin, mainly when the disease-free interval is more than two years.
Laparoscopic hepatectomy has become the golden standard mainly for left side resections, due to lower morbidity, shorter hospital stay, early recovery and good cosmetic outcome. The authors report the case of a female patient with two hatman metastases ten years of disease-free survival, of non-colorectal origin adenocarcinoma of small intestine, treated by laparoscopic left lateral segmentectomy left hepatic lobectomy with success. The postoperative progress was satisfactory.
To date, the patient has presented no tumoral recurrence six months of follow-up period. Laparoscopic left lateral segmentectomy can be satisfactorily performed in hsrtman cases of hepatic metastasis.
This approach presents low morbidity and good cosmetic result.

The lack of alternative treatments and the poor prognosis of untreated cases have justified surgical resection in order to increase overall survival. Nevertheless, this approach should be performed by hepatic surgery expertise teams trained on advanced laparoscopic procedures.
No grupo 1, receberam 1. Fatal pulmonary thromboembolism in gastrectomy intraoperative procedures by gastric adenocarcinoma: Full Text Available The case of a patient with gastric adenocarcinoma with indication for gastrectomy is reported. The surgery took place without complications. A palliative, subtotal gastrectomy was performed after para-aortic lymph nodes compromised by neoplasm were found, which was confirmed by pathological exam of frozen sections carried out during the intervention.
At the end of the gastroenteroanastomosis procedure, the patient began to show intense bradycardia: Resuscitation maneuvers were performed with temporary success. Subsequently, the patient had another circulatory breakdown and again was recovered. Finally, the third cardiac arrest proved to be irreversible, and the intra-operative death occurred. Necropsy showed hwrtman pulmonary embolism. The medical literature has recommended heparinization of patients, in an colosstomia to avoid pulmonary thromboembolism following major surgical interventions.
However, in the present case, heparinization would have been insufficient to prevent death. This case indicates that it is necessary to develop preoperative propedeutics for diagnosing the presence of venous thrombi with potential to migrate, causing pulmonary thromboembolism PTE.
If such thrombi could be detected, preventative measures, such as filter installation in the Cava vein could be undertaken. Sporadic colorectal cancer is rarely associated with synchronous lesions. To investigate the role of mismatch repair gene mutation haartman synchronous sporadic colorectal cancer.
Patients with sporadic synchronous colorectal adenocarcinomas were included in the study. All patients had two synchoronous lesions. One patient had altered MSH6 expression in both tumors. Possibly, other molecular colostomix are involved in carcinogenesis of sporadic synchronous colorectal cancer. One-hundred patients 54 men and 46 women, who have received treatment for CRA, stage I – 44 patients and stage IV – 56 patients, have been studied. Histological cuts of tumor tissue were examined by the immunohistochemical technique as to the expression of E-cadherin proteins.
Such histological cuts were classified as positive or negative through the semi-quantitative method. Regarding the cell differentiation degree, the expression of E-cadherin, GI: Because the elderly population in Brasil is rapidly increasing, the colorectal surgeron will always manage extremely old patients, aged 75 or 85 years or older, with the diagnosis of colorectal cancer.
The management of such cases is controversial.

This paper reports the treatment of a year-old patient with diagnosis of rectum adenocarcinomaand presents a literature review on the best approach for old-age patients with colorectal cancer. The patient underwent a palliative laparoscopic retossigmoidectomy and colorectal anastomosis, as the specimen was resected through supra-pubic transverse.
As pessoas que apresentassem resultado negativo eram cadastradas para exame de controle anual. The oxidative stress can cause errors in the pairing of nitrogenous bases that. Estudaram-se casos de CCR diagnosticados consecutivamente segundo protocolo de rotina. In Brazil, colorectal carcinoma CRC is the third cause of death by malignant tumors among women and the fifth among men. To analyze the pathologic characteristics of CRC in Brazilian patients. Pathologic characteristics were analyzed according to the patients’ gender and age and tumor location.
The median age was No association was found. Urachal adenocarcinoma is a rare tumor and represents. Most of the reported cases are in western literature and to the best of our knowledge this is the first case report of urachal adenocarcinoma in sub-Saharan Africa. It has an insidious course and variable clinical presentation. The metalloproteinase-1 MMP-1 and metalloproteinase-7 MMP-7 are proteinases of the extracellular matrix MEC, zinc-dependent, involved in the initial process of carcinogenesis, allowing the invasion by the tumor cell and promoting the process of metastasis.
Evidence shows cumulative important role of MMPs 1 and 7 in different stages of carcinogenesis. Its increased expression in this tissue may indicate high potential for spread in different tumor types of cancer, including colorectal. The association of this increase of expression also appears to be true for MMP Surgical resection is the mainstay of treatment for colorectal cancer with curative intent.
