[Prospects for development of laparoscopic surgery in the Central Federal District of the Russian Federation]. / O perspektive razvitiya laparoskopicheskoi khirurgii v Tsentral'nom federal'nom okruge Rossiiskoi Federatsii.

OBJECTIVE: To analyze the achievements of laparoscopic surgery in the Central Federal District of Russia and outline perspective trends for further application. MATERIAL AND METHODS: The study included adult patients with abdominal surgical diseases hospitalized in general surgical departments of the Central Federal District between 2014 and 2021. We analyzed the prevalence of elective and emergency laparoscopic surgeries. Incidence and results of laparoscopic interventions between 2018 and 2021 were estimated considering primary statistical data presented in the annual collections of the Chief Surgeon of the Ministry of Health of Russia «Surgical care in the Russian Federation¼. RESULTS: The absolute number of laparoscopic surgeries in the Central Federal District increased from 23.686 to 80.489 (by 3.4 times) between 2014 and 2021. The annual number of elective laparoscopic surgeries exceeded the number of emergency ones up to 2019. In 2020-2021, this situation changed in favor of emergency abdominal procedures. Laparoscopic surgeries are the most common for in acute cholecystitis (71.06-81.10% of all laparoscopic interventions annually) and acute appendicitis (46.85-55.60%). In 2020 and 2021, the absolute number of laparoscopic appendectomies exceeded the number of laparoscopic cholecystectomies. These values are lower for perforated ulcers (15.44-20.39%) and acute pancreatitis (32.40-36.71%). Laparoscopic operations are rare for acute intestinal obstruction, strangulated hernia and ulcerative gastroduodenal bleeding. In elective surgery, high availability of laparoscopic surgeries was noted in patients with cholelithiasis (89.40-93.78%), hiatal hernia (62.12-77.27%) and adrenal gland diseases (64.23-87.25%). The most intensive increment of availability (by 2.4 times) was noted for inguinal hernia from minimum level (10.98%) in 2018 to 26.00% in 2021. Mortality after some laparoscopic operations decreased in comparison with laparotomy by 12-45 times (2018-2021). However, this aspect and results of laparoscopic surgeries in case of delayed hospitalization require additional study. CONCLUSION: Analysis of laparoscopic surgery showed the timeliness of beginning and development of this direction In Russia. The prospect of further development of laparoscopic surgery for abdominal diseases is determined by modern trends. These are increase in the number of laparoscopic operations for acute appendicitis, acute cholecystitis and perforated ulcers, as well as higher number of early (after admission) operations.

[Impact of late admission on mortality from acute abdominal diseases in the Central Federal District of the Russian Federation]. / Vliyanie pozdnei gospitalizatsii na letal'nost' pri ostrykh abdominal'nykh zabolevaniyakh v TsFO Rossiiskoi Federatsii.

OBJECTIVE: To analyze the effect of late hospitalization on mortality from acute abdominal diseases in the Central Federal District of the Russian Federation. MATERIAL AND METHODS: Analysis of late hospitalizations and in-hospital mortality was based on metadata (616.742 clinical observations between 2017 and 2021). Primary statistical data were obtained from reports of chief surgeons in 18 regions of the Central Federal District of the Russian Federation and presented in analytical collections «Surgical care in the Russian Federation¼. RESULTS: The number of patients admitted to surgical hospitals of the Central Federal District with acute abdominal diseases later than 24 hours from clinical manifestation varies depending on the underlying disease. The greatest number of late hospitalizations was observed in acute intestinal obstruction (50.82%), acute adhesive intestinal obstruction (48.49%) and acute pancreatitis (47.36%). In acute cholecystitis, gastrointestinal bleeding and acute appendicitis, admission after 24 hours was observed in 44.72, 38.65 and 33.83% of cases, respectively. Late hospitalization is even less typical for strangulated hernia (27.43%) and perforated ulcer (26.23%). In-hospital mortality significantly differs in both groups (within and after 24 hours) for all acute abdominal diseases. Extended surgery and widespread peritonitis increase these differences for strangulated hernia by 9.2 times (0.92% within 24 hours and 8.48% after 24 hours), for acute appendicitis by 8 times (0.05% within 24 hours and 0.40% after 24 hours) and for perforated ulcer by 6.3 times (4.50% within 24 hours and 28.59% after 24 hours). CONCLUSION: In the Central Federal District, about 25-50% of patients with acute abdominal diseases admitted to the hospital later than 24 hours after clinical manifestation depending on disease. We found the highest in-hospital mortality following late hospitalization in patients with strangulated hernia, acute appendicitis and perforated ulcers.

[In-hospital mortality in acute abdominal diseases in the Central Federal District of Russia depending on availability of laparoscopic procedures]. / Dinamika gospital'noi letal'nosti pri ostrykh abdominal'nykh zabolevaniyakh v Tsentral'nom federal'nom okruge Rossii v zavisimosti ot chastoty primeneniya laparoskopicheskikh operatsii.

OBJECTIVE: To study in-hospital mortality in acute abdominal diseases in the Central Federal District and compared effectiveness of laparoscopic and open surgeries. MATERIAL AND METHODS: The study was based on the previous data for 2017-2021. The odds ratio (OR) was used to assess significance of between-group differences. RESULTS: The absolute number of deceased patients with acute abdominal diseases increased significantly and exceeded 23 thousand in the Central Federal District between 2019 and 2021. This value approached 4% for the first time over the last 10 years. In-hospital mortality from acute abdominal diseases in the Central Federal District increased for 5 years and reached maximum value in 2021. The greatest changes occurred in perforated ulcers (mortality increased from 8.69% in 2017 to 14.01% in 2021), acute intestinal obstruction (from 4.7% to 9.0%) and ulcerative gastroduodenal bleeding (from 4.5% to 5.5%). In other diseases, in-hospital mortality is lower, but trends are similar. Laparoscopic surgeries are common in acute cholecystitis (71-81%). At the same time, in-hospital mortality is significantly lower in regions with more active use of laparoscopy (0.64% and 1.25% in 2020; 0.52% and 1.16% in 2021). Laparoscopic surgeries are significantly less actively used for other acute abdominal diseases. We analyzed availability of laparoscopic surgeries using the «Hype Cycle¼. Percentage range of introduction reached conditional «productivity plateau¼ only in acute cholecystitis. CONCLUSION: Most regions are stagnating in laparoscopic technologies for acute appendicitis and perforated ulcers. Laparoscopic operations are actively used for acute cholecystitis in most regions of the Central Federal District. Annual increase in the number of laparoscopic operations and their technical improvement are promising in reducing in-hospital mortality associated with acute appendicitis, perforated ulcers and acute cholecystitis.

[Impact of staffing on the results of treatment among surgical patients. Statistical study]. / Vliyanie kadrovoi ukomplektovannosti na rezul'taty lecheniya khirurgicheskikh bol'nykh. Statisticheskoe issledovanie.

OBJECTIVE: To study the influence of staffing index on the results of surgical treatment. MATERIAL AND METHODS: The study was based on the data of surgical service in the Russian Federation upon 2018 (A.Sh. Revishvili et al., 2019). Correlation and regression analysis was carried out using the Microsoft Excel 2019 software. To assess between-group differences, we analyzed odds ratio (OR) and contingency table using χ2 test. RESULTS: Correlation and regression analysis revealed strong direct functional relationships (r=0.889) between the staffing of surgical service and in-hospital mortality rates. We distinguished 3 formalized levels of surgical staffing (high, medium and low). Gradation of these categories depends on the annual average reference indicator of staffing (88.4% in 2018). In high level of surgical staffing (≥88.4%), in-hospital mortality was 2.19%. Low level of surgical staffing (<88.4%) is accompanied by in-hospital mortality of 2.65% (OR 0.83; 95% CI 0.81-0.84; p<0.05). CONCLUSION: We confirmed the hypothesis about correlation of in-hospital mortality and staffing of surgical personnel. Validation of scientific data requires further studies with multivariate analysis of various covariates. Long-term prospects of surgical personnel policy in Russia are associated with formulation of specific tasks for surgical services at each level of surgical care.

[Effectiveness of laparoscopic cholecystectomy for acute cholecystitis]. / Sravnitel'naya effektivnost' laparoskopicheskoi kholetsistektomii pri ostrom kholetsistite.

OBJECTIVE: To analyze the impact of laparoscopic cholecystectomy on in-hospital and postoperative mortality in patients with acute cholecystitis. MATERIAL AND METHODS: Comparative analysis was based on primary statistical data presented in public available analytical collections «Surgical care in the Russian Federation¼ (Revishvili A.Sh. et al. 2019, 2020). Depending on introduction of laparoscopic surgery, all regions were divided into 4 groups. Between-group analysis of differences was carried out using χ2 test. Statistical processing was performed using SPSS Statistics software package for Windows. RESULTS: According to 2-year follow-up data (2018, 2019), in-hospital mortality was 0.97 and 0.95% and postoperative mortality was 1.36 and 1.47%, respectively, in the regions with percentage of laparoscopic surgery for patients with acute cholecystitis was less than 25%. In the second group (percentage of laparoscopic surgery 25.01 - 50%), in-hospital mortality was 0.95 and 1.14%, postoperative mortality - 1.38 and 1.71%. In the third group (percentage of laparoscopic surgery 50.01 - 75%), in-hospital mortality was 0.92 and 0.99%, postoperative mortality - 1.27 and 1.38%. In the fourth group, percentage of laparoscopic surgery exceeded 75%. In-hospital mortality was 0.61 and 0.74%, postoperative mortality - 0.76 and 0.98%, respectively. Analysis of multi-field contingency tables revealed non-random between-group differences of in-hospital (p<0.001) and postoperative (p<0.001) mortality, as well as significant decrease of mortality following laparoscopic surgery. We also analyzed mortality after laparoscopic surgery considering technology maturity curve. CONCLUSION: In-hospital and postoperative mortality in acute cholecystitis depend on availability of laparoscopic technologies.

[Surgical risks and their prevention in laparoscopic cholecystectomy].

It was analyzed the treatment results of 3739 patients with chronic and acute cholecystitis who underwent laparoscopic cholecystectomy. Three groups of predisposing factors were determined in 427 high risk patients. Laparoscopic cholecystectomy in view of these factors and enhancement of approach to dissect gall-bladder decreases the number of intraoperative complications.
