[Predicting the course of urgent abdominal diseases based on intensity of catabolic phenomena]. / Prognozirovanie techeniya urgentnykh zabolevanii zhivota na osnove otsenki intensivnosti katabolicheskikh yavlenii.

OBJECTIVE: To develop a highly informative method for predicting the course of early postoperative period in urgent abdominal surgery based on indicators of lipid metabolism. MATERIAL AND METHODS: We analyzed 113 patients with acute surgical abdominal disease including 56 (49.6%) ones with acute appendicitis complicated by peritonitis, 23 (20.4%) ones with acute intestinal obstruction complicated by peritonitis and 34 (30.0%) patients with acute moderate pancreatitis (early phase). Leukocyte count, malondialdehyde, medium-weight molecules and lipid composition (phospholipid lysoforms) were analyzed throughout a 5-day period. Considering these data, we developed a method for predicting the course of early postoperative period (patent). RESULTS: Original method is highly effective in predicting the course of early postoperative period in urgent abdominal diseases. Sensitivity and specificity of this method for acute abdominal diseases complicated by acute peritonitis are 94.7% and >86.3%, for acute pancreatitis - 92.7 and 85.4%, respectively. CONCLUSION: Efficacy of original method is determined by analysis of catabolic phenomena, i.e. indicators of tissue destruction. Of course, assessment of endogenous intoxication whose toxins are components of catabolic (membrane-destructive) processes is essential.

[Enteral protection in patients with diffuse peritonitis]. / Enteroprotektsiya v povyshenii effektivnosti lecheniya patsientov s rasprostranennym peritonitom.

OBJECTIVE: To improve treatment outcomes in patients with diffuse peritonitis via enteral protection using intestinal lavage with ozonized solution through an original tube. MATERIAL AND METHODS: We analyzed 78 patients with advanced peritonitis. The control group included 39 patients who underwent standard measures after surgery for peritonitis. The main group consisted of 39 patients who underwent early postoperative intestinal lavage with ozonized solutions through original tube for 3 days. RESULTS: Clinical and laboratory parameters, as well as ultrasound data indicated better correction of enteral insufficiency in the main group. Morbidity in the main group was lower by 33.3%, length of hospital-stay - by 3.5 days. CONCLUSION: Early postoperative intestinal lavage with ozonized solutions through original tube accelerates recovery intestinal function and improves treatment outcomes in patients with widespread peritonitis.

[Optimization of early postoperative period in intestinal resection surgery for acute intestinal obstruction complicated by peritonitis]. / Optimizatsiya rannego posleoperatsionnogo perioda v rezektsionnoi khirurgii kishechnika pri ostroi kishechnoi neprokhodimosti, oslozhnennoi peritonitom.

OBJECTIVE: To establish the effectiveness of complex therapy with Remaxol in optimizing the early postoperative period and increasing the reparative ability of intestinal tissues in acute intestinal obstruction complicated by peritonitis. MATERIAL AND METHODS: We analyzed treatment outcomes in 37 patients with acute intestinal obstruction complicated by peritonitis. The control group included 19 patients who underwent standard therapeutic measures after resolving intestinal obstruction and resection of small or large intestine. The main group consisted of 18 patients who underwent intraoperative intestinal lavage with Remaxol through a probe and early postoperative intravenous infusions (800 ml within 2 days and 400 ml for subsequent 3 days). RESULTS: The main group was characterized by positive dynamics of clinical and laboratory parameters, in particular, relief of endogenous intoxication syndrome, reduction of oxidative stress and phospholipase activity, general hypoxia. Postoperative morbidity in the main group decreased by 61.7% (χ2=3.897, p<0.05). Better tissue healing in the area of intestinal anastomosis and laparotomy under Remaxol therapy was demonstrated. CONCLUSION: Inclusion of Remaxol in complex therapy of acute intestinal obstruction complicated by peritonitis can significantly improve treatment outcomes, reduce the number of complications and increase reparative potential of tissues. Positive effect of this drug is based on less oxidative stress, phospholipase activity and hypoxia.

[Correction of enteral distress syndrome in acute intestinal obstruction]. / Korrektsiya enteral'nogo distress-sindroma pri ostroi kishechnoi neprokhodimosti.

OBJECTIVE: On the basis of a comprehensive assessment of the functional state of the intestine in acute mechanical small bowel obstruction, to justify adequate schemes of its protection. MATERIAL AND METHODS: A clinical and laboratory study of 48 patients with acute small bowel obstruction developed against the background of abdominal adhesions, strangulated abdominal hernia was conducted. The first group (n=25) of patients who underwent laparotomy, removal of intestinal obstruction (adhesiolysis and/or herniation, hernial gate plastic surgery), intestinal intubation, standardized therapy after surgery. The second group (n=23) - patients, therapy included Remaxol (Polysan Pharmaceutical Plant, Petersburg): 400.0 enterally intraoperatively through a probe after nasointestinal intubation, evacuation of stagnant contents and intestinal lavage with isotonic saline solution; 400.0 - intravenously for 5 days. A number of indicators of homeostasis (endogenous intoxication, oxidative stress), structural and functional state of the intestine were evaluated. RESULTS: It was found that the inclusion of remaxol in complex therapy (intraoperatively and in the early postoperative period) leads to the optimization of the treatment process of patients with acute intestinal obstruction. The number of complications according to the Clavien-Dindo classification decreased from 17 (first) up to 5 (second group) (χ2=3.988, p=0.046). Hospital stay decreased from 12.8±1.1 to 10.1±0.8 bed days (p<0.05). The effectiveness of the developed scheme is based on its ability to correct the phenomena of enteral distress syndrome relatively quickly, which was confirmed by laboratory and instrumental methods. The most important manifestation of this was a significant decrease in the phenomena of endogenous intoxica tion against the background of a significant decrease in the activity of peroxidation of membrane lipids - triggers of catabolic intestinal lesions. CONCLUSION: Studies document the effectiveness of the developed treatment regimen for patients with acute intestinal obstruction. The inclusion of remaxol parenterally and enterally makes it possible to significantly optimize the course of the early postoperative period. One of the main objects of its implementation was the relatively rapid restoration of intestinal function, reduction of manifestations of enteral distress syndrome. This provided rapid relief of endogenous intoxication and, as a result, prevented the progression of the systemic inflammatory response syndrome, which together determined the optimization of the early postoperative period.

[Possible ways to approach the effectiveness of open abdominal interventions to laparoscopic]. / Vozmozhnye puti priblizheniya rezul'tativnosti otkrytykh abdominal'nykh vmeshatel'stv k laparoskopicheskim.

THE PURPOSE OF THE WORK: Based on the determination of the mechanisms of negative manifestations of surgical aggression in open interventions, compared with laparoscopic, to determine ways to optimize the early postoperative period when using them. MATERIAL AND METHODS: The work is based on clinical and laboratory analysis of 147 patients with acute appendicitis complicated by acute peritonitis. In the first group (n=58), patients were operated with traditional laparotomy access. In the second group (n=47) - laparoscopic interventions were used. In the first and second groups, traditional therapy was carried out according to clinical recommendations. In the third group (n=42), patients were operated with traditional laparotomy access, and in the early postoperative period, their therapy included remaxol (intravenous injections of 800.0 ml of the drug in the first two days, then within three days - 400.0 ml). Laboratory and instrumental studies were carried out in patients, including the level of hydrophilic and hydrophobic toxins in the blood, the intensity of peroxidation of membrane lipids and antioxidant enzyme potential, the activity of phospholipase A2. The functional status of the intestine and liver was assessed. RESULTS: It was found that the most important manifestation of the reduction of surgical aggression in the early stages after surgery, which is characteristic of laparoscopic operations, are significantly low phenomena of endogenous intoxication against the background of a significant decrease in the activity of peroxidation of membrane lipids and phospholipase systems - triggers of catabolic phenomena and lesions of various organs and systems, including the intestine and liver. The inclusion of remaxol in complex therapy for patients who have undergone open surgical operations leads to a number of positive clinical and laboratory effects. The most important of them is the reduction of endogenous intoxication. This beneficial effect is associated with the restoration of the functional status of the intestine and liver, as well as a decrease in the severity of catabolic phenomena. The effectiveness of complex therapy with remaxol was marked by reducing the number of postoperative complications and the length of the patient's stay in the hospital. CONCLUSION: The use of remaxol in patients with acute peritonitis complicated by peritonitis who have undergone open surgical interventions, due to the relatively rapid restoration of the functional status of the intestine and liver, reduction of catabolic phenomena, reduces the severity of endogenous intoxication syndrome, which was the basis for a significant improvement in the course of the early postoperative period, bringing it closer to that when using laparoscopic technology.

[The variants of enteral distress syndrome correction with peritonitis]. / Puti korrektsii enteral'nogo distress-sindroma pri rasprostranennom peritonite.

OBJECTIVE: To determine the effectiveness of a new treatment regimen for patients with widespread peritonitis with an accent on enteroprotection based on the use of a drug of the metabolic type of action of remaxol and physiotherapy. MATERIAL AND METHODS: Clinical and laboratory studies of 82 patients with widespread peritonitis, mainly with grade 2 severity according to the Mannheim peritonitis Index, severe form - according to the ARASNE II scale. In the 1st group (28) patients underwent intraoperative intestinal intubation in the traditional way; in the 2nd (22) - intestinal intubation according to the original method; in the 3rd (32) - intestinal intubation according to the original method and combined use of remaxol (parenterally, enterally and intraperitoneally). An intestinal tube of an original design was used, which allows electrical stimulation of the duodenum in the postoperative period. The study evaluates clinical data, the results of instrumental and laboratory studies: ultrasound examination of the abdominal cavity, assessment of the functional state of the small intestine, a number of indicators of homeostasis. RESULTS: It was shown that in patients with acute widespread peritonitis who underwent intestinal intubation according to the original method (group 2), as well as in combination with remaxol (group 3), the postoperative period was relatively more favorable. One of the factors optimizing the course of the disease was the relatively rapid restoration of the structural and functional state of the small intestine due to its electrical stimulation. The clinical and laboratory positive effect was especially significant in the 3rd group of patients, in which the use of remaxol, which has a membrane-stabilizing effect, played a special role in the enteroprotective effect. Timely correction of enteral distress syndrome resulted in a significant decrease in the severity of the syndrome of endogenous intoxication and oxidative stress, which was important in significantly improving the results of treatment of patients. CONCLUSION: The use of technical innovations in the form of an original nasointestinal tube, which allows to quickly restore intestinal motility due to electrical stimulation, as well as the use of remaxol (parenterally, enterally and intraperitoneally) significantly optimize the course of the early postoperative period of patients with acute widespread peritonitis.

[Hepatic distress syndrome in surgery: concept, pathogenesis, prevention and correction]. / Gepaticheskii distress-sindrom v khirurgii: ponyatie, patogenez, osnovy profilaktiki i korrektsii.

OBJECTIVE: To establish the universality and regularity of hepatic disorders, their role in pathogenesis of homeostasis impairment and determine scientific base for a new syndrome - hepatic distress syndrome in surgery. MATERIAL AND METHODS: Chronic experiments on outbred dogs were carried out. Acute peritonitis was simulated in the first group (n=15), acute destructive pancreatitis in the second group (n=15), acute obstructive intestinal obstruction in the third group (15). In the fourth group, experimental acute peritonitis (n=15) was followed by Remaxol infusions (20 ml/kg). Liver function was evaluated using the indicators of endogenous intoxication, lipid metabolism markers, as well as composition of lipids in liver tissue. Clinical studies included 44 patients with peritonitis (the first subgroup - standard therapy (n=20), Remaxol infusion in the second subgroup (n=24), severe acute pancreatitis (n=18), acute adhesive intestinal obstruction (n=20)). Patients underwent surgery. Along with routine indicators, we analyzed severity of endogenous intoxication, lipid peroxidation, phospholipase activity, serum lipids and red blood cell count. RESULTS: Experimental and clinical studies have shown significant liver damage in all diseases with various pathogenesis. Regardless of urgent disease, one of the leading component is membrane-destabilizing process. The last one is determined by excessive activity of membrane lipid peroxidation and phospholipases in liver tissue. Severe abnormalities are followed by impairment of liver detoxification ability and liver may be a source of toxins per se. Remaxol infusion in the treatment of experimental and clinical acute peritonitis increased liver tolerance to trigger pathogenetic agents. This process resulted improvement of laboratory and clinical parameters. In general, we obtained high significance of liver damage in pathogenesis of acute urgent abdominal pathology. CONCLUSION: Experimental and clinical data for determining hepatic distress syndrome as important aspect in acute abdominal surgical diseases have been obtained. Hepatic distress syndrome in surgery is a combination of abnormal processes with progression of endogenous intoxication, oxidative stress and phospholipase activity following membrane-destabilizing phenomena and secondary liver dysfunction.

[Factor analysis of clinical and paraclinical criteria determining the prognosis of acute renal damage].

AIM: to identify risk factors and assess their significance in the development and prognosis of acute kidney injury in urological patients. MATERIAL AND METHODS: The data of 6272 patients treated in the Department of Urology and Intensive care Unit were analyzed retro- and prospectively. Factorial and linear regression analyzes of the primary diagnostic criteria were carried out, which allowed to establish an impact of individual signs and their combination in determining the risk of developing or diagnosing existing renal dysfunction in the absence of clinical manifestations. RESULTS: Statistical analysis has demonstrated the high significance of some diagnostic criteria (gender, increased body mass index, duration of the disease, comorbidities, hyperthermia, epitheliuria, proteinuria) influencing the development of acute kidney injury in patients with urolithiasis complicated by renal colic or secondary pyelonephritis. The factor load of each criterion allowed to establish the worst prognosis and the risk of progression of acute kidney injury in patients with frequent recurrences of secondary pyelonephritis, episodes of renal colic over the last 5 years, a combination of arterial hypertension and diabetes mellitus who underwent extracorporeal shock-wave lithotripsy or pyelolithotomy with nephrostomy. These risk factors require for additional pharmacological protective therapy aimed at preventing the progression of acute kidney injury. CONCLUSIONS: Decreased urine output and serum creatinine levels as criteria for acute kidney injury (according to KDIGO) do not allow to fully assess the risk of renal dysfunction, which requires to consider additional criteria (gender, increased body mass index, duration of the disease, comorbidities, hyperthermia, epitheliuria, proteinuria) when taking history during the initial examination of a patient with upper urinary tract pathology.

[Membrane protection of intestine and liver cells in the effectiveness of minimally invasive surgery for acute peritonitis]. / Otsenka effektivnosti mini-invazivnykh vmeshatel'stv pri ostrom peritonite na osnovanii izucheniya funktsional'nogo sostoyaniya pecheni i kishechnika.

OBJECTIVE: To determine the value of membrane protective effect in intestine and liver cells for the effectiveness of minimally invasive surgery for acute peritonitis. MATERIAL AND METHODS: Patients with acute peritonitis undergoing laparoscopic (n=60) and open (n=50) surgery are analyzed. Functional characteristics of liver and bowel, disorders of homeostasis were evaluated in early postoperative period. RESULTS: Reduced negative impact of surgical aggression on the state of liver and intestine is essential to improve treatment outcomes in patients with acute peritonitis undergoing minimally invasive surgery. Fast recovery of intestine inevitably results reduced release of endotoxins while restoration of liver function is associated with rapid elimination of these toxins. These processes prevent severe intoxication and facilitate accelerated recovery. Functional restoration of liver and bowel is associated with reduced oxidative stress during laparoscopic operations. It is also important because peritonitis causes activation of free-radical processes per se. Therefore, an additional source of oxidative phenomena is extremely undesirable in these cases. CONCLUSION: Laparoscopic surgery for acute peritonitis minimizes surgical aggression and is associated with more favorable recovery of liver and bowel function. Undoubtedly, these findings should be considered to choose surgical approach in this severe category of patients.
