RESUMEN
OBJECTIVE: To evaluate the quality of recommendations provided by ChatGPT regarding inguinal hernia repair. MATERIAL AND METHODS: ChatGPT was asked 5 questions about surgical management of inguinal hernias. The chat-bot was assigned the role of expert in herniology and requested to search only specialized medical databases and provide information about references and evidence. Herniology experts and surgeons (non-experts) rated the quality of recommendations generated by ChatGPT using 4-point scale (from 0 to 3 points). Statistical correlations were explored between participants' ratings and their stance regarding artificial intelligence. RESULTS: Experts scored the quality of ChatGPT responses lower than non-experts (2 (1-2) vs. 2 (2-3), p<0.001). The chat-bot failed to provide valid references and actual evidence, as well as falsified half of references. Respondents were optimistic about the future of neural networks for clinical decision-making support. Most of them were against restricting their use in healthcare. CONCLUSION: We would not recommend non-specialized large language models as a single or primary source of information for clinical decision making or virtual searching assistant.

Optimal treatment for adhesive small bowel obstruction (SBO) is not defined. Surgery is the only method of treatment for obvious strangulating SBO. Non-operative management (NOM) is widely used among patients with low risk of strangulation, i.e. no clinical, laboratory and CT signs. Randomized controlled trials (RCTs) are recommended to determine the optimal method (early intervention or NOM), but their safety is unclear due to possible delay in surgery for patients needing early intervention. MATERIAL AND METHODS: A RCT is devoted to outcomes of early operative treatment and NOM for adhesive SBO. The estimated trial capacity is 200 patients. Thirty-two patients were included in interim analysis. In 12 hours after admission, patients without apparent signs of strangulation were randomized into two clinical groups after conservative treatment. Group I included 12 patients who underwent immediate surgery, group II - 20 patients after 48-hour NOM. The primary endpoint was success of non-surgical regression of SBO and reduction in mortality. To evaluate patient safety, we analyzed mortality, complication rates and bowel resection in this RCT with previously published studies. RESULTS: In group I, all 12 (100%) patients underwent surgery. Only 4 (20%) patients required surgery in group II. Mortality, complication rates and bowel resection rates were similar in both groups. Strangulating SBO was found in 8 (25%) patients. Overall mortality was 6.3%, bowel resection rate - 6.3%, iatrogenic perforation occurred in 3 (18.8%) patients. These values did not exceed previous findings. CONCLUSION: Non-operative management within 48 hours prevented surgery in 80% of patients with SBO. Interim analysis found no significant between-group differences in mortality, complication rates and bowel resection rate. Patients had not been exposed to greater danger than other patients with adhesive SBO. The study is ongoing.

BACKGROUND: Posterior component separation with transversus abdominis release (TAR) is considered to be the optimal technique for large incisional ventral hernia repair. Endoscopic TAR (eTAR) that gets all the benefits of minimally invasive surgery (MIS) gives a possibility to enhance results of the treatment. The aim of our study was to make the comparison between open and endoscopic TAR procedures with an emphasis on frequency and severity of postoperative complications in comparable groups. MATERIALS AND METHODS: All patients had midline incisional hernia and underwent either open (open TAR group) or endoscopic (eTAR group) Rives-Stoppa repair in combination with bilateral transversus abdominis release in Moscow City Hospital â1 from January 2018 to December 2022. A propensity score matching (PSM) was used to make groups comparable. Postoperative complications were classified according to Clavien-Dindo Classification, and Comprehensive complication index was calculated. RESULTS: We performed 133 open and endoscopic TAR separation for midline incisional hernia. After PSM analysis 51 patients were matched to each group. Overall surgical morbidity in the open TAR group (56.9%) was statistically significantly higher than in the eTAR group (29.4%) (p = 0.009). There were more severe complications (Clavien IIIa-V) in the open TAR group (11.8% vs. 0%, p = 0.027). Length of hospital stay after surgery was shorter in eTAR group (p < 0.001). The Comprehensive complication index in the open TAR group was significantly higher than in eTAR group, 8.7 (0-20.9) vs. 0 (0-8.7) (p = 0.011). CONCLUSION: Based on the data from our study, the entire MIS procedure including endoscopic TAR is a safe and optimal technique for surgery of midline incisional ventral hernia, requiring TAR separation in terms of reducing the rate of postoperative complications, their severity and hospital length of stay, compared to open TAR procedure.
RESUMEN
Introduction: Complicated diverticulitis is a common abdominal emergency that often requires a surgical intervention. The systematic review and meta-analysis below compare the benefits and harms of robotic vs. laparoscopic surgery in patients with complicated colonic diverticular disease. Methods: The following databases were searched before 1 March 2023: Cochrane Library, PubMed, Embase, CINAHL, and ClinicalTrials.gov. The internal validity of the selected non-randomized studies was assessed using the ROBINS-I tool. The meta-analysis and trial sequential analysis were performed using RevMan 5.4 (Cochrane Collaboration, London, United Kingdom) and Copenhagen Trial Unit Trial Sequential Analysis (TSA) software (Copenhagen Trial Unit, Center for Clinical Intervention Research, Rigshospitalet, Copenhagen, Denmark), respectively. Results: We found no relevant randomized controlled trials in the searched databases. Therefore, we analyzed 5 non-randomized studies with satisfactory internal validity and similar designs comprising a total of 442 patients (184 (41.6%) robotic and 258 (58.4%) laparoscopic interventions). The analysis revealed that robotic surgery for complicated diverticulitis (CD) took longer than laparoscopy (MD = 42 min; 95% CI: [-16, 101]). No statistically significant differences were detected between the groups regarding intraoperative blood loss (MD = -9 mL; 95% CI: [-26, 8]) and the rate of conversion to open surgery (2.17% or 4/184 for robotic surgery vs. 6.59% or 17/258 for laparoscopy; RR = 0.63; 95% CI: [0.10, 4.00]). The type of surgery did not affect the length of in-hospital stay (MD = 0.18; 95% CI: [-0.60, 0.97]) or the rate of postoperative complications (14.1% or 26/184 for robotic surgery vs. 19.8% or 51/258 for laparoscopy; RR = 0.81; 95% CI: [0.52, 1.26]). No deaths were reported in either group. Discussion: The meta-analysis suggests that robotic surgery is an appropriate option for managing complicated diverticulitis. It is associated with a trend toward a lower rate of conversion to open surgery and fewer postoperative complications; however, this trend does not reach the level of statistical significance. Since no high quality RCTs were available, this meta-analysis isnot able to provide reliable conclusion, but only a remarkable lack of proper evidence supporting robotic technology. The need for further evidence-based trials is important.
RESUMEN
INTRODUCTION: The rate of electrosurgery complications is 0.1-2.1%. More than 10 years ago, SAGES pioneered a well-structured educational program (FUSE) aimed to teach about the safe use of electrosurgery. This inspired the development of similar training programs around the globe. Still, the knowledge gap persists among surgeons, possibly due to the lack of judgment. AIM: To investigate factors affecting the level of expertise in electrosurgical safety and their correlation with self-assessment scores among surgeons and surgical residents. MATERIALS AND METHODS: We conducted an online survey consisting of 15 questions that could be thematically broken down into 5 blocks. We analyzed how the objective scores were correlated with the self-assessment scores, professional experience, past participation in training programs, and work at a teaching hospital. RESULTS: A total of 145 specialists took part in the survey, including 111 general surgeons and 34 s-year surgical residents from Russia, Belarus, Ukraine, and Kirgizia. Only 9 (8.1%) surgeons scored "excellent," 32 (28.8%) scored "good," and 56 (50.4%) scored "fair." Of all surgical residents participating in the study, only 1 (2.9%) scored "excellent," 9 (26.5%) scored "good," and 11 (32.4%) scored "fair." The test was failed by 14 surgeons (12.6%) and 13 (38.2%) residents. The difference between the trainees and the surgeons was statistically significant. Our multivariate logistic model identified 3 significant factors predisposing to successful performance on the test: past training in the safe use of electrosurgery, professional experience, and work at a teaching hospital. Of all study participants, those with no past training in the safe use of electrosurgery, and non-teaching surgeons were the most realistic about their competencies. CONCLUSION: We have identified alarming gaps in the knowledge of electrosurgical safety among surgeons. Faculty staff and experienced surgeons scored higher, but past training was the most influential factor in improving knowledge of electrosurgical safety.

INTRODUCTION: Spontaneous bleeding into the soft tissues of the abdominal and thoracic wall is described as complication of anticoagulant therapy. Computed tomography (CT) allows to detect the presence of extravasation of the contrast agent into a hematoma, which is indicated as a sign of ongoing bleeding. Other specific CT signs of such coagulopathic bleeding have been described earlier. AIM OF THE STUDY: To evaluate the significance of specific coagulopathic CT signs for predicting the dynamics of spontaneous bleeding into soft tissues in patients with COVID-19. MATERIALS AND METHODS: A retrospective study included 60 patients with COVID-19 with spontaneous bleeding into soft tissues and extravasation of a contrast agent on CT. In addition to extravasation, a "hematocrit effect" was detected in 43 patients on CT. Of these, 39 had extravasation in the form of a "signal flare." All patients underwent transarterial catheter angiography (TCA). To assess the prognostic value of CT signs, the results of CT and TCA compared. The absence of extravasation on the TCA more often corresponded to stopped bleeding. RESULTS: Extravasation on TCA found in 27 (45%) patients. The presence of the "hematocrit effect" or the combination of this sign with the phenomenon of a "signal flare" on CT (n = 43) led to more frequent confirmation of extravasation on TCA than in their absence (n = 17): 23.5% vs. 53.4% (p = 0.028). CONCLUSION: The presence of a fluid level and the phenomenon of a "signal flare" on CT in the structure of spontaneous hematomas of the soft tissues of the abdominal and thoracic wall in COVID-19 patients more often corresponded to ongoing bleeding on the TCA. The absence of coagulopathic CT signs more often corresponded to stopped bleeding.

OBJECTIVE: To assess the level of knowledge in electrosurgical safety among specialists in the Russian Federation. MATERIAL AND METHODS: An Internet survey was devoted to the issues of electrosurgical safety. The questionnaire consisted of 15 questions in 5 items. Data were collected for 2 months. Data analysis included final assessment of respondents, correlation of results with their own assessment of knowledge and parameters of surgical experience, the fact of training and belonging to the department. Question design, survey and presentation of results were performed in accordance with the CHERRIES (Check list of Reporting Results of Internet E-Surveys) criteria for Internet surveys. RESULTS: Survey enrolled 231 specialists. Excellent rating was given to 13 (5.6%) respondents, good - 66 (28.3%), satisfactory - 105 (45.1%) respondents. Forty-nine (21.03%) respondents did not overcome the passing score (7) and showed unsatisfactory knowledge of electrosurgical safety. Mean score among all participants was 8.6±2.6 (median 8 points, interquartile range [7-11]) or 53.3% of maximum value (15). In multivariate logistic model, significant factors were the completed course in electrosurgical safety (OR 2.26, 95% CI 1.30-3.97; p=0.004), experience of work (OR 1.03, 95% CI 1.01-1.05; p=0.011) and work in the department (OR 1.74, 95% CI 1.03-2.95; p=0.038). Respondents who did not take the course (positive significant correlation r=0.1629, p=0.02674) and non-departmental employees (r=0.1655, p=0.031) assess the level of knowledge more adequately with respect to real results. Respondents with completed course (r=0.1078, p=0.4659) and departmental staff (r=0.1411, p=0.2699) are prone to overestimate self-assessment (positive insignificant correlation of their own assessment and received points). CONCLUSION: We found significant knowledge gaps in electrosurgical safety among various practitioners. The main causes are no mandatory specialized courses on electrosurgical safety and insufficient motivation of specialists for self-education due to false ideas about their own level of knowledge.

BACKGROUND: The problem of venous thromboembolic events (VTE) after incisional hernia repair remains relevant. According to the literature the frequency of VTE ranges from 0.2 to 4.2%. The data on risk factors of VTE in this cohort of patients are scarce. Aim of our study is to find frequency and risk factors for VTE development in patients who underwent surgery for incisional ventral hernia. MATERIALS AND METHODS: There were 240 patients enrolled in our retrospective study. We included patients, who were operated for incisional hernia in Saveljev University Surgery Clinic from January 2018 to December 2019. Compression duplex ultrasound of lower extremity veins was performed within median 3 days (min 1 day, max 7 days) after surgery for all participants. The primary endpoint was the occurrence of the VTE event, including deep venous thrombosis (DVT) and pulmonary embolism (PE). RESULTS: VTE was detected in 19 patients, which accounted for 7.9% in analyzed cohort. All patients received standard pharmacological prophylaxis. There were 3 (1.3%) proximal, 16 (6.7%) distal DVT, in one patient (0.4%) distal thrombosis was complicated by symptomatic pulmonary embolism. In multivariate Cox proportional hazard model was found that component separation (HR 3.99, 95% CI 1.14-14.0, p = 0.03), duration of operation in hours (HR 1.67. 95% CI 1.13-2.5, p = 0.011) and body mass index (HR 1.13, 95% CI 1.02-1.2, p = 0.02) were statistically significant risk factors. CONCLUSION: The incidence of postoperative VTE in patients after incisional hernia repair is high with a predominant distal DVT as a thrombotic event. Component separation, duration of operation and body mass index are statistically significant factors of VTE in patients undergoing surgery for incisional hernia.

OBJECTIVE: To investigate the results of therapeutic and prophylactic endovascular hemostasis of spontaneous bleeding into soft tissues of abdominal, chest wall and retroperitoneal space in patients with COVID-19. MATERIAL AND METHODS: We retrospectively studied 35 patients with COVID-19 complicated by spontaneous bleeding into soft tissues of abdominal, chest wall and retroperitoneal space. According to CT data, the volume of hematoma was 1193.4±706.1 ml. In all patients, CT signs of ongoing bleeding were detected. Moreover, contrast agent extravasation in all phases of examination was established in 15 patients. In other ones, extravasation was detected in late phases or study phase was not identified. All patients underwent angiography. Ongoing bleeding was detected in 12 (34.3%) patients (group 1). They underwent embolization of the target vessel. In 23 patients, bleeding was not established during angiography. Of these, 13 ones underwent prophylactic embolization (group 2). No embolization was carried out in 10 patients (group 3). All groups differed in hematoma localization and COVID-19 severity. RESULTS: Fourteen (40%) patients died in postoperative period. Mortality was similar in all groups. The most common cause of death was progressive respiratory failure following pneumonia. The last one was established by autopsy in 10 (71.4%) patients. CONCLUSION: Angiography confirmed MR signs of contrast agent extravasation in 34.3% of patients. In case of extravasation in all CT phases, ongoing bleeding was confirmed in 66.7% of patients. Endovascular embolization is effective for arterial bleeding into soft tissues. However, large-scale studies are needed to assess the effect of this technique on survival.

OBJECTIVE: To evaluate the accuracy of clinical, laboratory and instrumental methods for diagnosis of intestinal ischemia following small bowel obstruction in emergency hospitals. MATERIAL AND METHODS: Multiple-center observational retrospective study enrolled 158 consecutive patients with benign small bowel obstruction (SBO) treated at four hospitals between May 2017 and December 2019. The role of clinical, laboratory and instrumental diagnostic methods for intestinal ischemia was analyzed. We assessed the impact of CT and contrast-enhanced X-ray examination on survival of patients. RESULTS: Laboratory parameters as criteria of ischemia following SBO were similar (leukocytosis >14·109/l (p=1.0), serum lactate >2.0 mmol/l (p=0.28), heart rate >90/min (p=0.71) and fever (p=0.74)). The only laboratory indicator with significant differences was serum sodium. Decrease in leukocytosis over time was less common in patients with ischemia (25% vs. 61.3%, p=0.012). Univariate Kaplan-Meier analysis did not establish the effect of CT on survival (7.8% [95% CI 7.6-8.0] vs. 6.5% [95% CI 6.3-6.6], p=0.786). Logistic regression revealed 6.4-fold higher chance of accurate diagnosis (ischemia/non-ischemia) in case of CT-based conclusion of ischemia (95% CI 0.025-0.85). Univariate analysis showed that the use of water-soluble contrast for adhesive SBO was associated with lower mortality (4.1% [95% CI 4.0-4.2] vs. 14.3% [95% CI 13.7-14.9], p=0.032) without assessing the comparability of groups. CONCLUSION: Routine laboratory tests were not specific for intestinal ischemia. Therefore, they should not be considered as the only criteria for surgical tactics in intestinal obstruction. Only CT showed acceptable diagnostic accuracy, and, apparently, only this method has real prospects for improving the quality of diagnosis due to technical support, training of surgeons and specialists for diagnosis.

OBJECTIVE: To study the Cochrane evidence base of systematic reviews and meta-analyses regarding development of national guidelines for surgical treatment of gallstone disease and its complications. MATERIAL AND METHODS: We analyzed the original database involving 35 systematic reviews and meta-analyses of Cochrane Library devoted to gallstone disease and its complications. Methodology of electronic and manual searching of trials was used for identification and screening of information for the period until October 2021. RESULTS: There were 430 randomized controlled trials from different countries estimated in 35 systematic reviews of Cochrane Library. At the same time, Russian-language researches are not included in the world's evidence database of biliary tract surgery. Expert groups couldn't perform meta-analysis and limited to systematic-review in 6 (17%) publications because of insufficient statistical power or primary researches. Need for further research of this issue was determined after assessment of 26 (74%) meta-analyses. CONCLUSION: We have to convey foreign experience as subbase of national clinical guidelines taking into account deficiency of scientific trials with high level of evidence in our country. Need for further evidence trials, considering the peculiarities of surgical care in the Russian Federation, is determined by unsolved issues of treatment of gallstone disease and its complications.

OBJECTIVE: Comparative assessment of immediate and long-term results of robot-assisted and conventional endoscopic technologies in the Russian Federation. MATERIAL AND METHODS: Searching for primary trials devoted to robot-assisted (RAE) and traditional video endoscopic (TVE) surgeries in the Russian Federation was carried out in the e-library and CENTRAL Cochrane databases. We used the recommendations of the Center for Expertise and Quality Control of Medical Care (2017, 2019) and the current version of the Cochrane Community Guidelines (2021). These guidelines define the features of meta-analysis of non-randomized comparative studies. Review Manager 5.4 software was used for statistical analysis. RESULTS: We enrolled 26 Russian-language primary sources (3111 patients) including 1174 (38%) ones in the RAE group and 1937 (62%) patients in the TVE group. There were no randomized controlled trials in the Russian Federation, and all primary studies were non-randomized. We found no significant between-group differences in surgery time, incidence of intraoperative complications, intraoperative blood loss in thoracic surgery, urology and gynecology, conversion rate, postoperative hospital-stay, postoperative morbidity (in abdominal surgery, urology and gynecology), postoperative mortality. We observed slightly lower intraoperative blood loss for RAE in abdominal surgery and lower incidence of postoperative complications in robot-assisted thoracic surgery. These results can be compromised by methodological quality of comparative studies, significant heterogeneity and systematic errors. CONCLUSION: Currently, we cannot confirm the benefits of robot-assisted technologies, since this approach does not worsen or improve treatment outcomes. Further high-quality studies are needed.

OBJECTIVE: To study surgical approach for small bowel obstruction (SBO) regarding national and international guidelines. MATERIAL AND METHODS: Considering literature data, national and international guidelines and clinical practice, we have formulated 15 questions regarding surgical approach for non-neoplastic SBO. Questions were sent by e-mail to the members of the Russian Society of Surgeons. Survey lasted 60 days. We used the program that provides the respondent with the possibility of visual control of survey results. Survey results were compared with national and international clinical guidelines, Russian- and English-language scientific publications. Restriction of the number of votes >1 and identification of respondents were not provided by the program. There was no reward for survey. A summary is provided on the main issues. RESULTS: There were 557 respondents (3.0% of surgeons in the Russian Federation). We obtained 481-620 answers for each question. CONCLUSION: This study is a valuable tool for primary assessment of current surgical practice for SBO in the Russian Federation. Study design did not imply conclusions on the optimal strategy based on opinions of majority of respondents. According to our survey, a significant number of respondents use the treatment strategy that differ from clinical guidelines. Their approach is based on their own clinical experience and local guidelines for the treatment of SBO. Less than half of the answers matched to national clinical guidelines, less than 10% - to the WSES guidelines. Despite the formal coincidence of some statements in national clinical guidelines and English-language recommendations, significant nonconformities require scientific discussion.

OBJECTIVE: To study the effectiveness of enhanced recovery after surgery (ERAS) protocol versus traditional perioperative management in patients with hepatopancreatobiliary tumors undergoing pancreatoduodenectomy. MATERIAL AND METHODS: The study included 111 patients who have undergone pancreatoduodenectomy between January 2014 and December 2019. Patients were divided into 2 groups: perioperative ERAS protocol (85 patients) and traditional treatment (26 patients). Postoperative complications, length of hospital-stay and incidence of readmissions were analyzed. RESULTS: Mean length of hospital-stay for ERAS protocol was 13.4±7.6 days, conventional management - 16.5±7.5 days (p=0.004). Postoperative 30-day mortality was 8.24 and 7.7% in both groups, respectively (p=1.0). Intraoperative blood loss was significantly less in the ERAS group (248.24±214.0 vs. 321.15±155.0 ml, p=0.004). Overall incidence of postoperative complications was 56.5% and 65.4%, respectively (p=0.420). However, incidence of Clavien-Dindo grade IV complications was significantly higher in case of traditional treatment (19.2 vs. 4.7%, p=0.015). Readmission rate within 30 days was slightly less in the ERAS group (6.4 vs. 20.8%, p=0.052). CONCLUSION: Enhanced recovery after surgery protocol is safe, reduces the number of postoperative complications, length of hospital-stay and rate of readmissions.

This review is devoted to history of pancreatodigestive anastomoses (PDA), technique of the most popular PDA, causes of pancreatic fistula and its prevention. Contradictory data were obtained in randomized trials and meta-analyses devoted to pancreatic anastomoses. There is no optimal anastomosis excluding clinically significant postoperative pancreatic fistula. Therefore, further studies should be aimed at new approaches reducing the incidence of clinically significant postoperative pancreatic fistula.

OBJECTIVE: To analyze the factors of mortality in patients with acute adhesive small bowel obstruction (ASBO). MATERIAL AND METHODS: A retrospective multiple-center study included 143 (85.6%) patients with ASBO out of 167 consecutive patients with small bowel obstruction for the period 2017-2019. All patients were divided into 3 groups: early surgery group (within 12 hours after admission), late surgery (after 12 hours), non-surgical management group. The outcomes and Kaplan-Meier survival were compared in all groups. RESULTS: ASBO was resolved without surgery in 77 (53.8%) patients 19.6±17.4 (M=14) hours. In the Early Surgery Group (n=36), 24 patients had strangulation, 12 ones had non-strangulated bowel obstruction. In the Late Surgery Group (n=30), 15 patients had strangulation and 15 ones had no strangulation. Mortality was similar in early and late surgery (p=0.287), early and late surgery in patients with strangulation (p=0.940), early and late surgery in patients without strangulation (p=0.76). Patients died (n=10) after surgery only. Thus, postoperative mortality was 15.2%, overall mortality - 7.0%. All patients who underwent surgery after 24 hours (n=14) survived. Surgery increased the mortality risk compared to non-surgical management (95% CI 0 - 15.9, p=0.001). There was no effect of surgery time (more or less than 12 hours) on mortality for strangulation (95% CI 13.0-16.7, p 0.788) and non-strangulated obstruction (95% CI 29.4-5.4, p=0.061), bowel resection (95% CI 33.3-14.0, p=0.187), presence of bowel ischemia (95% CI 14.3-17.9, p 0.613). CONCLUSION: Delayed surgery may be advisable in patients with ASBO and no obvious signs of strangulation due to less mortality.

OBJECTIVE: To analyze the role of mesoappendixectomy in the development of intra-abdominal surgical site infection (IAB SSI) after LAE. MATERIAL AND METHODS: A prospective randomized non-blind multiple-center registered (ClinicalTrials.gov NCT03754777) study has been performed for the period from 2016 to 2018. The study was devoted to effectiveness and safety of the modified enhanced recovery protocol in LAE. In the main group, this protocol (n=56) included routine mesoappendixectomy, restrictive strategy for abdominal drainage and postoperative antibiotic prevention. In the control group (n=71), mesoappendixectomy was performed only in case of necrotic changes. Both groups were comparable by demographic parameters and severity of comorbidities. RESULTS: In the main group, significant decrease in the incidence of IAB SSI was found (0% versus 9.8%). Moreover, the main group was characterized by reduced length of hospital-stay (1.43±1.34 d versus 2.94±2, 43 days). CONCLUSION: Mesoappendixectomy should be evaluated in further research as a potential factor in prevention of IAB SSI.
