Аннотация
Установлено, что частота ИОХВ у пациентов с КРР составляет 26- 27%. Выявлена зависимость между послеоперационными осложнениями и отдаленными результатами радикального хирургического лечения КРР: любые послеоперационные осложнения снижают долгосрочную выживаемость после хирургического лечения КРР; инфекционные осложнения являются основной причиной снижения выживаемости в данной группе больных, хотя у пациентов с высоким предоперационным риском чаще развиваются неинфекционные осложнения; больные с тяжелой формой инфекции области хирургического вмешательства имеют самый плохой прогноз долгосрочного выживания. Частота инфекционных осложнений после операций по поводу КРР служит показателем качества и безопасности хирургической помощи, и, по-видимому, сможет выступать предиктором вероятных результатов лечения.
Ключевые слова: колоректальный рак, хирургическое лечение, инфекция области хирургического вмешательства, отдаленные результаты.

(LITERARY OVERVIEW)
Abstract
It is established that the frequency SSI in patients with CRC is 26- 27%. Correlation between postoperative complications and long-term results of radical surgical treatment of CRC: any postoperative complications decrease long-term survival after surgical treatment of CRC; infectious complications are a major cause of reduced survival in this group ofpatients, although patients with high preoperative risk often develop non-infectious complications; patients with severe form of surgical site infections have a bad prognosis long-term survival. Strategies to prevent infectious complications and implement more intensive surveillance protocols for those with severe infections may improve quality of care and long-term outcomes in patients undergoing curative-intent surgery for CRC.
Keywords: colorectal cancer, surgical treatment, surgical site infections, long-term results.
Colorectal cancer (CRC) is among the most common cancers. According to the International Agency for research on cancer (IARC), the incidence of CRC in the world is 1.5 million cases per year, and the mortality rate exceeds 500 thousand persons [1,2 ]. In the structure of causes of death of these patients is actually the CRE and its complications (about 75%). However, 25% of patients as such are concomitant diseases of the cardiovascular system, gastrointestinal tract, trauma and suicide [3-5]. Universal method for the treatment of CRE does not exist, in most cases the treatment of choice is surgery associated with the development of postoperative complications on average in 20-25% of cases [6, 7], with up to 75-80% of all complications are infectious [8]. Surgical treatment of CRC in late stages characterized by a deterioration of the immediate (increase in the frequency of complications and re-operations) and remote (often local recurrence, decrease five-year survival rate) results. Infectious complications in the postoperative period are a cause of death in 7.4% of cases [9].
Despite the increase in preventive measures, the problem surgical site infection (SSI) is becoming increasingly important and is one of the most popular options among all the infections associated with health care (IAHC) [10-16].According to studies conducted in the United States, the frequency SSI in patients with CRC was 26.2% [17, 18], in Russia - 27% [19]. In the structure of complications is dominated by a superficial wound infection, but the most dangerous are deep IAHC and sepsis. As for the reasons for the prevalence of different forms IAHC, they largely depend on the localization of the tumor. In patients with colon cancer surface IAHC was 12.8%, deep - 2,1%, organ - 8,4% (23,2%), in patients with rectal neoplasm: surface SSI- 13,6%, deep - 5.7%, the region operated on - 8,3% (a total of 27.6% of complications) [20].
The risk of developing SSI if the CRE is caused by complex pathogenic factors: dysmotility and secretion of the colon, change the quantitative and qualitative composition of the mucosal and luminal microflora and an increased likelihood of translocation of endogenous flora into the abdominal cavity and systemic circulation. In addition, resection of the colon in scheduled colorectal surgery is associated with the opening of the lumen of the organ and the likely contamination of the wound gram-negative rods, enterococci, non-clostridial anaerobes. At the same time respect all the rules of asepsis and antisepsis does not allow guaranteed to avoid microbial contamination of the wound [4, 9]. Increases the likelihood of SSI the total weight of the patient, a decrease in the immunological status of elderly and senile age patients, metabolic disorders due to tumor progression and comorbidities (diabetes, obesity). Besides the negative impact of long duration and invasiveness of surgery, perioperative hypoxia, little experience and insufficient skill of the surgeon [21].
Late contamination of surgical wounds is particularly likely with the use of drains, formation of ileo - or colostomy. Source of complications is usually the microflora of the skin, mucous membranes, the spread of germs from a distant focus of infection. In addition, they can be medical personnel, surgical instruments and medical supplies (exogenous factor) [11]. The consequences of contamination and outcome of the infection process is influenced by characteristics of flora and the degree of protection of the patient, considering the initial immunological status, impact of preoperative comprehensive treatment
(chemotherapy and radiotherapy). If this serious problem is high resistance of microorganisms to antibiotic treatment and more severe course of IAHC [22-24].
Risk factor for all forms SSI - superficial, deep, region operated on - it becomes the traditional "open" surgery. Laparoscopic surgery reduces the chance of contamination of the wound and the abdominal cavity. However, the introduction of rigorous robotic surgery has not led to a significant reduction in SSI in connection with the negative impact of increasing the duration of the activity [25] on average, more than 3 hours. In addition, the development of the IAHC are important risk factors as age of patients older than 60 years, presence of diabetes, ulcerated tumors, blood loss more than 750 ml, absence of perioperative antibiotic prophylaxis, duration of standing of a urinary catheter for more than 7 days and standing drains more than 5 days after surgery [26].
It is important to emphasize that the development of infectious complications associated with a particular group of patients [8]: they are in average younger than patients with non-infectious complications, and had better nutritional status and lower risk of operative intervention on the ASA scale. Infectious complications were more often observed in stage III disease, the tumor is in the rectum, often conducted neoadjuvant radiation therapy. In the group of patients without complications were more often adjuvant (postoperative) chemotherapy when the tumor in the colon on the background of the early stages of the disease. Postoperative complications of surgery of the CRE, especially SSI -the main cause of poor immediate results [25,26]. Postoperative complications increase the time and cost of treatment, leads to death [26, 27]. In addition, there is a relationship between early postoperative complications and decrease survival of patients in long-term period [28-30]. This is especially true of the impact of deep wound infection and insolvency seams inter-intestinal anastomosis [30-33].
So the median survival in CRC patients without postoperative complications amounted to 41.9 months. and in the group with complications - 34.2 months. With the development of non-infectious complications patients lived an average of 39.3 months. and in the group with infectious complications - 32.9 months. And after a mild infectious complications (superficial infection of the wound), the median survival was 39.7 months. a group of patients with severe infection (deep infection of the wound and infection of the operated on, an inconsistency of seams intestinal anastomosis) - 32.0 months. [8]. Organo-abdominal SSI are serious purulent complications, with a twofold increase in the risk of re-hospitalization, 75% increased risk of death [30].
Explain impact of infectious complications on long-term results of treatment of CRC include: 1. the release of proinflammatory cytokines from inflammation [33, 34, 35] provokes tumor progression; 2. communication development SSI with III-IV stage of disease [36]; 3. delay the timing of adjuvant treatment (chemotherapy) or full refusal in patients with postoperative infectious complications [34] reduces the effectiveness of anti-tumor effects; 4. admission into the abdominal cavity of viable tumor cells from the lumen of the colon in insolvency seams inter-intestinal anastomosis [32, 37, 38] contributes to the dissemination of the tumor; 5. unsatisfactory technique of surgical intervention, predisposes to local recurrence and infectious complications [ 8,39].
The impact of infectious complications, particularly severe cases SSI on the long-term survival was noted after operations on the colon and other malignant tumors [30, 40-45]. The review Mirnezami et al. [32] revealed a twofold increase in risk of local recurrence and a 75% increase in risk of death at long-term periods in insolvency seams anastomosis compared to patients without this complication. Tokunaga et al. [41] demonstrated a significant (2-fold) increase in the risk of local recurrence and death in patients with intraabdominal infectious complications after radical operations for cancer of the stomach. Andalib et al. [42] found the worst long-term results in patients with lung cancer after severe infectious complications, who underwent resection treatment options.
Thus, if further research confirmed that infectious complications in the early postoperative period (SSI) significant influence, including, and long-term outcomes of surgical intervention about CRC, they may serve, on the one hand, indicators of quality and safety of surgical care, on the other, is likely to be predictors of treatment outcomes.
