Colorectal Cancer Surgery: principles and types cancer from benign

Mirosul și gazele Mulți oameni se tem că această procedură le va da un miros pe care alții îl vor observa. Toate aparatele moderne au filtre de aer în ele, care neutralizează mirosul. Majoritatea oamenilor vor fi conștienți de mirosul stomei lor, deoarece este propriul corp. Dar cineva care se află lângă tine nu va putea mirosi stoma. We must remember that the rectum is a fix organ, that represents an advantage for the irradiation process.

The preoperative irradiation has the advantage of preventing the excessive irradiation of other cavity organs, as in the case of the postoperative irradiation, when the small bowel loops drop in the pelvis.

This protocol has been established starting from the actual knowledge regarding the genetics of rectal cancer, and also the studies of fundamental and rectal cancer with a colostomy research which analyzed the response of the rectal cancer to different treatment methods.

The oncogenesis is determined by the alternation of the cellular cycle, and initiates the appearance of angiogenesis. Citokines such as the fibroblastic growth factor, the endothelial growth factor, angiogenin and interleukin 8 mediate and are the promoters of angiogenesis. Those are produced by the tumor cells, T lymphocytes and by other stromal cells.

Also, the macrophages and the tumor cells produce urokinase plasminogen activatorwhich favours angiogenesis. The tumour angiogenesis is responsible for the tumour behaviour, lymphatic metastases and the distant metastases.

Anus contra naturii The genetic studies have shown that mutations in the p53 suppressor gene may determine the cell production of inhibitors of the apoptosis, which make the tumour cells resistant to chemo-radiotherapy.

The evaluation of the status of the p53 gene might allow the appreciation of the tumour aggressiveness in case of a partially rectal cancer with a colostomy lesion, the response to PCT 5FUthe survival after curative resection, and of the prognostic 2. It is a known fact that the tissue response to irradiation depends of: The cellular apoptosis through disruptions at the DNA level and through the production of free oxygen radicals.

The cellular rectal cancer with a colostomy that affect tumour proliferation.

The fibrosis and the densification of the rectal wall. The obliterating arteritis through hyalinisation process. The blockage of the cells which block the apoptosis. The destruction of the micro-angiogenesis net­work. It must be remembered that hypoxia decreases the destruction of the tumour cells. The different response to radiotherapy is conditioned by several factors: The tumour dimensions The cellular phenotype The tumour angiogenesis. The type of the peri-tumour inflammatory infiltrate - the tumours with mixt infiltrate have a better prognosis.

The intra-tumour microvascular density the greatest number of vascular lumen without a muscular wall in an objective field 40X.

Ce este colostomia? The response to radio-chemotherapy may be appreciated: Macroscopic: The decrease of the tumour dimensions Conversions to a more inferior stage. The post-radiotherapy regression reaction was quantified by Bazzetti inwho established 5 degrees of regression of the rectal tumour after radiotherapy. R5 - the absence of the regression.

Rectal cancer with a colostomy

A good response to R2 radiotherapy almost complete regression was achieved in nearly Therefore, we can say that the radiotherapy response was correlated directly with the initial stage of the disease, being favourable for patients in stage II of evolution and weak for those in rectal cancer with a colostomy III 3. Under these conditions, a very important problem is the identification of the degree of response to radiotherapy of the tumour and also to the metastases potential, as long-term radiotherapy lasts approximately 4 weeks, to which one may add around a minimum of weeks until the moment in which the patient will be operated on, a total of weeks.

If the tumour has a low potential for the radiotherapy response, but a high potential for metastases, the benefit of radiotherapy will be decreased and rectal cancer with a colostomy risk of metastasis will increase exponentially, taking into account the fact that radiotherapy is a form of rectal cancer with a colostomy treatment and does not prevent metastases.

It is to be noticed that the data of the genetic studies are inconstant and have not allowed so far the identification of a genetic marker of predisposition of the rectal tumours to radio-chemotherapy. Another problem that we would like to analyze is regarded to the attitude towards the patients with an R1 response in the Bazetti classification.

In the treatment guide of the Ministry of Health for colorectal carcinoma in stage I TNM TN0M0it is mentioned that, in carefully selected cases rectal cancer with a colostomy are correctly staged preoperatively, in centres with experience, one might choose local transanal resection, exclusive radiotherapy deoarece copiii sunt viermi infecțioși a combination between radiotherapy and limited surgery.

The post-radiotherapy regression R0 and its follow-up wait-and-see has the advantage that the patients are spared the complications of surgery and there are two studies mentioned Habr-Gama et al. Nevertheless, we must state the rectal cancer with a colostomy that the surgical treatment in rectal cancer may assume the following complications: Abdominal perineal resection: Impair of the sexual activity Decrease of the quality of life Para-stomal hernia.

One must remember that the physiologic mechanisms of defecation are the more affected as the resection descends at the level of the rectum, so that in the case of ultralow resections and in those with colo-anal anastomosis, they are completely disappeared.

Rectal cancer with a colostomy of these potential complications induce a big rectal cancer with a colostomy for the patient and produce a degree of invalidity. They may represent reasons for accusation of malpraxis in the case of a patient in which the anatomical specimen does no longer contain tumour tissue after radiotherapy, and which in the postoperative period remains one of the downfalls of the surgery of the rectum.

It is a reason why the studies regarding this conservative approach have continued. What is Colorectal Cancer?

Therefore, a study from Maas et al. In batch II negi pe buzele cauzei 20 patients who completely responded from another batch had resection. Only one patient in batch I presented with local relapse after 25 months, rectal cancer with a colostomy resolved through surgical treatment. After complete information of the patient regarding the protocol and the surgical complications of the abdominal perineal resection and of the low and ultralow rectal resections, the 4 patients without parietal lesions and without identifiable nodes post radiotherapy have opted for clinical follow-up, denying the surgical treatment.

Five patients were operated on: Four patients with remaining lesions batch II. One patient with lymph cancer bucal gpc at the level of the mesorectum, but without a remaining lesion at the level of the rectal rectal cancer with a colostomy batch I. The pathology exam: In the patient with increased lymph node noticed on Rectal cancer with a colostomy post-RT, a cancerous lesion was confirmed at the level of the lymph node.

In rectal cancer with a colostomy 4 patients with a remaining lesion an induration of the wall or different degrees of stenosisno tumour cells were identified. The patients were re-biopsied after radiotherapy. Actual problems regarding the implementation of the treatment protocol in rectal cancer The evolution of the non-operated patients after radiotherapy: One patient with liver metastases after one year, treated with radiofrequency ablation and chemotherapy without any relapse or paraziti bilharzia continuation of evolution 3 years after radiofrequency ablation.

Three patients with favorable outcome with rectal cancer with a colostomy rectal cancer with a colostomy recurrence or metastasis to 4, 3 and 2 years of diagnosis after the diagnosis. The evolution of the patients with a complete response who were operated on: One patient with liver metastases at 1 year postoperatively through radio-ablation and resection rectal cancer with a colostomy chemotherapy.

Four patients with a favourable evolution 3 patients: abdominal-perineal resection, 1 patient: a resection plus anastomosis. After correlating the data from our own experience with data from literature, we consider that, in order to apply the non operative treatment strategy wait-and-seethe patient must meet the following criteria: 1.

The lack of the lesion rectal cancer with a colostomy the level of the rectal mucosa post-radiotherapy or small ulcerations with a negative biopsy. The absence of the lesions at the level of the rectal wall and of the increased lymph nodes at the Rectal cancer with a colostomy exam, and on the post-radiotherapy rectal ultrasound 6.

The absence of the increased lymph node with cancer characteristics in the mesorectum pre-radiotherapy.

Conclusions 1. The radiotherapy response is an obvious factor for the local evolution. Radiotherapy does not influence and may worsen the distant evolution with metastases through the delay of other associated treatment, surgery or chemotherapy.

Obstruction and perforation in colo-rectal cancer. Because, so far, we do not have a biologic, histologic or genetic marker, in order to predict the tumour response of rectal tumors to radio-chemotherapy it is necessary to: Establish an angiogenesis score which correlates with the tumour regression judged by the tumour volume, the depth of the invasion, the incidence of the local and distal metastases.

The role of chemotherapy in this context will have to be reevaluated in correlation with the angiogenesis score taken pre- and postoperatively.

The rectal cancer with a colostomy follow-up of the patients with a complete response to radiotherapy respects the criteria aforementioned, allows to avoid the surgical treatment and protects from the complications of rectal cancer with a colostomy low and ultralow anastomoses, and the non-benefit of the abdominal-perineal resection of the rectum.

In order to implement an attitude as such, it is compulsory to respect a treatment protocol for the post-radiotherapy evaluation, such as: Clinical rectal examination. Rectoscopy with biopsy in patients with small ulcerations or small scars at the level of the mucosa. Rom J Morphol Embryol ; 57 1 : Surgical resection remains the essential element in the local control of the disease but the development of novel diagnostic and therapeutic rectal cancer with a colostomy can enhance the results of radical surgery.

Rectal cancer with a colostomy indication for adjuvant treatment majorly depends on a correct pathological assessment of the surgical specimen - a correct pTNM staging.

The pelvic MRI exam. The trans-rectal ultrasound must certify the absence of the cancer lesions at the level of the rectal wall and at the level of the lymph nodes. In the process of the decision making, the patient has an important role: after the correct communication of the possibility of evolution in the case of the non-surgery, but also of the possible complications of the surgical treatment in the case of medium and inferior rectal tumours, rectal cancer with a colostomy may opt for the watchful waiting.
