PreScheck Team Study: prehabilitation clinic as an effective patient management tool in elective cardiac surgery.

INTRODUCTION: The main purpose of the study was to assess the impact of preoperative interdisciplinary assessment by the PreScheck Team on optimization of the final selection for elective cardiac surgery. MATERIAL AND METHODS: This is a single-centre prospective observational study. The examined population consisted of 933 adult patients planned for cardiac surgery. After the exclusion of urgent operations, the study group consisted of 288 patients planned for elective cardiac surgery within 3 months from 1.01.2023 with PreScheck assessment (PreScheck Team group 2) and a control group of 311 patients scheduled for elective cardiac surgery between 1.03.2022 and 30.06.2022 (4 months), without preoperative interdiscipli-nary assessment (No PreScheck Team group 2). RESULTS: Fifty-two patients (18.06%) from the study group were finally excluded from the surgery on the scheduled date. In 46 patients (88.46%) the temporary or permanent exclusion from surgery was a result of PreScheck Team assessment. In the control group 42 patients (13.5%) did not undergo surgery on the scheduled date. Twenty-seven of those patients (8.97%) were permanently excluded from cardiac surgery after admission to the hospital and required additional tests before the final clinical decision, with total hospitalization time of 146 days. CONCLUSIONS: Pre Surgery Check (PreScheck) Team is an original concept that combines classical preoperative assessment and an outpatient prehabilitation clinic. The approach we are proposing here should be a complementary stage in the process of selection for elective cardiac surgery, in addition to the Heart Team recommendation. This two-step decision-making enables real individual risk assessment, selection of the most suitable intervention and better use of medical resources.

Evolution of enhanced recovery for children undergoing elective intestinal surgery.

Enhanced recovery protocols (ERP) have been widely adopted in adult populations, with over 30 years of experience demonstrating the effectiveness of these protocols in patients undergoing gastrointestinal (GI) surgery. In the last decade, ERPs have been applied to pediatric populations across multiple subspecialties. The objective of this manuscript is to explore the evolution of how ERPs have been implemented and adapted specifically for pediatric populations undergoing GI surgery, predominantly for inflammatory bowel disease. The reported findings reflect a thorough exploration of the literature, including initial surveys of practice/readiness assessments, consensus recommendations of expert panels, and data from a rapidly growing number of single center studies. These efforts have culminated in a national prospective, multicenter trial evaluating clinical and implementation outcomes for enhanced recovery in children undergoing GI surgery. In short, this historical and clinical review reflects on the evolution of ERPs in pediatric surgery and expounds upon the next steps needed to apply ERPs to future pediatric populations.

The impact of elective surgery postponement during COVID-19 on emergency bellwether procedures in a large tertiary centre in Singapore.

The coronavirus disease 2019 (COVID-19) pandemic drove many healthcare systems worldwide to postpone elective surgery to increase healthcare capacity, manpower, and reduce infection risk to staff. The aim of this study was to assess the impact of an elective surgery postponement policy in response to the COVID-19 pandemic on surgical volumes and patient outcomes for three emergency bellwether procedures. A retrospective cohort study of patients who underwent any of the three emergency procedures [Caesarean section (CS), emergency laparotomy (EL), and open fracture (OF) fixation] between 1 January 2018 and 31 December 2021 was conducted using clinical and surgical data from electronic medical records. The volumes and outcomes of each surgery were compared across four time periods: pre-COVID (January 2018-January 2020), elective postponement (February-May 2020), recovery (June-November 2020), and postrecovery (December 2020-December 2021) using Kruskal-Wallis test and segmented negative binomial regression. There was a total of 3886, 1396, and 299 EL, CS, and OF, respectively. There was no change in weekly volumes of CS and OF fixations across the four time periods. However, the volume of EL increased by 47% [95% confidence interval: 26-71%, P = 9.13 × 10-7) and 52% (95% confidence interval: 25-85%, P = 3.80 × 10-5) in the recovery and postrecovery period, respectively. Outcomes did not worsen throughout the four time periods for all three procedures and some actually improved for EL from elective postponement onwards. Elective surgery postponement in the early COVID-19 pandemic did not affect volumes of emergency CS and OF fixations but led to an increase in volume for EL after the postponement without any worsening of outcomes.

Is mechanical bowel preparation mandatory for elective colon surgery? A systematic review and meta-analysis.

BACKGROUND: Growing evidence demonstrates minimal impact of mechanical bowel preparation (MBP) on reducing postoperative complications following elective colectomy. This study investigated the necessity of MBP prior to elective colonic resection. METHOD: A systematic literature review was conducted across PubMed, Ovid, and the Cochrane Library to identify studies comparing the effects of MBP with no preparation before elective colectomy, up until May 26, 2023. Surgical-related outcomes were compiled and subsequently analyzed. The primary outcomes included the incidence of anastomosis leakage (AL) and surgical site infection (SSI), analyzed using Review Manager Software (v 5.3). RESULTS: The analysis included 14 studies, comprising seven RCTs with 5146 participants. Demographic information was consistent across groups. No significant differences were found between the groups in terms of AL ((P = 0.43, OR = 1.16, 95% CI (0.80, 1.68), I2 = 0%) or SSI (P = 0.47, OR = 1.20, 95% CI (0.73, 1.96), I2 = 0%), nor were there significant differences in other outcomes. Subgroup analysis on oral antibiotic use showed no significant changes in results. However, in cases of right colectomy, the group without preparation showed a significantly lower incidence of SSI (P = 0.01, OR = 0.52, 95% CI (0.31, 0.86), I2 = 1%). No significant differences were found in other subgroup analyses. CONCLUSION: The current evidence robustly indicates that MBP before elective colectomy does not confer significant benefits in reducing postoperative complications. Therefore, it is justified to forego MBP prior to elective colectomy, irrespective of tumor location.

The Effect of Dexmedetomidine as a Local Anesthetic Adjuvant for Iliac Fascia Compartment Block on Postoperative Delirium in Elderly Patients Undergoing Elective Hip Surgery.

INTRODUCTION: We analyzed the effect of dexmedetomidine (DEX) as a local anesthetic adjuvant on postoperative delirium (POD) in elderly patients undergoing elective hip surgery. METHODS: In this study, 120 patients undergoing hip surgery were enrolled and randomly assigned to two groups: fascia iliaca compartment block with DEX + ropivacaine (the Y group, n = 60) and fascia iliaca compartment block with ropivacaine (the R group, n = 60). The primary outcomes: presence of delirium during the postanesthesia care unit (PACU) period and on the first day (D1), the second day (D2), and the third day (D3) after surgery. The secondary outcomes: preoperative and postoperative C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), occurrence of insomnia on the preoperative day, day of operation, D1 and D2; HR values of patients in both groups before iliac fascia block (T1), 30 min after iliac fascia block (T2), at surgical incision (T3), 20 min after incision (T4), when they were transferred out of the operating room (T5) and after leaving the recovery room (T6) at each time point; VAS for T1, PACU, D1, D2; the number of patients requiring remedial analgesics within 24 h after blockade and related complications between the two groups. RESULTS: A total of 97 patients were included in the final analysis, with 11 and 12 patients withdrawing from the R and Y groups, respectively. The overall incidence of POD and its incidence in the PACU and ward were all lesser in the Y group than in the R group (p < 0.05). Additionally, fewer cases required remedial analgesia during the PACU period, and more vasoactive drugs were used for maintaining circulatory system stability in the Y group as compared to the R group (p < 0.05). At the same time, the incidence of intraoperative and postoperative bradycardia in the Y group was higher than that in the R group, accompanied by lower postoperative CRP and ESR (all p < 0.05). CONCLUSION: Ultrasound-guided high fascia iliaca compartment block with a combination of ropivacaine and DEX can reduce the incidence of POD, the use of intraoperative opioids and postoperative remedial analgesics, and postoperative inflammation in elderly patients who have undergone hip surgery, indicating that this method could be beneficial in the prevention and treatment of POD.

Cost saving in implementing ERAS protocol in emergency abdominal surgery.

INTRODUCTION: ERAS (Enhanced Recovery After Surgery) protocol is now proposed as the standard of care in elective major abdominal surgery. Implementation of the ERAS protocol in emergency setting has been proposed but his economic impact has not been investigated. Aim of this study was to evaluate the cost saving of implementing ERAS in abdominal emergency surgery in a single institution. METHODS: A group of 80 consecutive patients treated by ERAS protocol for gastrointestinal emergency surgery in 2021 was compared with an analogue group of 75 consecutive patients treated by the same surgery the year before implementation of ERAS protocol. Adhesion to postoperative items, length of stay, morbidity and mortality were recorded. Cost saving analysis was performed. RESULTS: 50% Adhesion to postoperative items was reached on day 2 in the ERAS group in mean. Laparoscopic approach was 40 vs 12% in ERAS and control group respectively (p ,002). Length of stay was shorter in ERAS group by 3 days (9 vs 12 days p ,002). Morbidity and mortality rate were similar in both groups. The ERAS group had a mean cost saving of 1022,78 € per patient. CONCLUSIONS: ERAS protocol implementation in the abdominal emergency setting is cost effective resulting in a significant shorter length of stay and cost saving per patient.

Bowel preparation for elective colectomy in Crohn's disease: results from a global cohort study using the NSQIP database.

AIM: The role of bowel preparation before colectomy in Crohn's disease patients remains controversial. This retrospective analysis of a prospective cohort study aimed to investigate the clinical outcomes associated with mechanical and antibiotic colon preparation in patients diagnosed with Crohn's disease undergoing elective colectomy. METHOD: Data were collected from the American College of Surgeons National Surgical Quality Improvement Program participant user files from 2016 to 2021. A total of 6244 patients with Crohn's disease who underwent elective colectomy were included. The patients were categorized into two groups: those who received combined colon preparation (mechanical and antibiotic) and those who did not receive any form of bowel preparation. The primary outcomes assessed were the rate of anastomotic leak and the occurrence of deep organ infection. Secondary outcomes included all-cause short-term mortality, clinical-related morbidity, ostomy creation, unplanned reoperation, operative time, hospital length of stay and ileus. RESULTS: Combined colon preparation was associated with significantly reduced risks of anastomotic leak (relative risk 0.73, 95% CI 0.56-0.95, P = 0.021) and deep organ infection (relative risk 0.68, 95% CI 0.56-0.83, P < 0.001). Additionally, patients who underwent colon preparation had lower rates of ostomy creation, shorter hospital stays and a decreased incidence of ileus. However, there was no significant difference in all-cause short-term mortality or the need for unplanned reoperation between the two groups. CONCLUSION: This study shows that mechanical and antibiotic colon preparation may have clinical benefits for patients with Crohn's disease undergoing elective colectomy.

Mechanical bowel preparation in elective colorectal surgery: a propensity score-matched analysis of the Italian colorectal anastomotic leakage (iCral) study group prospective cohorts.

Retrospective evaluation of the effects of mechanical bowel preparation (MBP) on data derived from two prospective open-label observational multicenter studies in Italy regarding elective colorectal surgery. MBP for elective colorectal surgery remains a controversial issue with contrasting recommendations in current guidelines. The Italian ColoRectal Anastomotic Leakage (iCral) study group, therefore, decided to estimate the effects of no MBP (treatment variable) versus MBP for elective colorectal surgery. A total of 8359 patients who underwent colorectal resection with anastomosis were enrolled in two consecutive prospective studies in 78 surgical centers in Italy from January 2019 to September 2021. A retrospective PSMA was performed on 5455 (65.3%) cases after the application of explicit exclusion criteria to eliminate confounders. The primary endpoints were anastomotic leakage (AL) and surgical site infections (SSI) rates; the secondary endpoints included SSI subgroups, overall and major morbidity, reoperation, and mortality rates. Overall length of postoperative hospital stay (LOS) was also considered. Two well-balanced groups of 1125 patients each were generated: group A (No MBP, true population of interest), and group B (MBP, control population), performing a PSMA considering 21 covariates. Group A vs. group B resulted significantly associated with a lower risk of AL [42 (3.5%) vs. 73 (6.0%) events; OR 0.57; 95% CI 0.38-0.84; p = 0.005]. No difference was recorded between the two groups for SSI [73 (6.0%) vs. 85 (7.0%) events; OR 0.88; 95% CI 0.63-1.22; p = 0.441]. Regarding the secondary endpoints, no MBP resulted significantly associated with a lower risk of reoperation and LOS > 6 days. This study confirms that no MBP before elective colorectal surgery is significantly associated with a lower risk of AL, reoperation rate, and LOS < 6 days when compared with MBP.

Evaluating the safety profile of anti-platelet therapy in patients undergoing elective inguinal hernia repair: a systematic review and meta-analysis.

INTRODUCTION: There remains no consensus surrounding the safety of prescribing anti-platelet therapies (APT) prior to elective inguinal hernia repair (IHR). AIMS: To perform a systematic review and meta-analysis evaluating the safety profile of APT use in patients indicated to undergo elective IHR. METHODS: A systematic review was performed in accordance with PRISMA guidelines. Meta-analyses were performed using the Mantel-Haenszel method using the Review Manager version 5.4 software. RESULTS: Five studies including outcomes in 344 patients were included. Of these, 65.4% had APT discontinued (225/344), and 34.6% had APT continued (119/344). The majority of included patients were male (94.1%, 288/344). When continuing or discontinuing APT, there was no significant difference in overall haemorrhage rates (odds ratio (OR): 1.86, 95% confidence interval (CI): 0.29-11.78, P = 0.130) and in sensitivity analysis using only RCT data (OR: 0.63, 95% CI: 0.03-12.41, P = 0.760). Furthermore, there was no significant difference in reoperation rates (OR: 6.27, 95% CI: 0.72-54.60, P = 0.590); however, a significant difference was observed for readmission rates (OR: 5.67, 95% CI: 1.33-24.12, P = 0.020) when APT was continued or stopped pre-operatively. There was no significant difference in the estimated blood loss, intra-operative time, transfusion of blood products, rates of complications, cerebrovascular accidents, myocardial infarctions, or mortality observed. CONCLUSION: This study illustrates the safety of continuing APT pre-operatively in patients undergoing elective IHR, with similar rates of haemorrhage, reoperation, and readmission observed. Clinical trials with larger patient recruitment will be required to fully establish the safety profile of prescribing APT in the pre-operative setting prior to elective IHR.

Development of a comorbidity index for patients undergoing abdominal aortic aneurysm repair.

BACKGROUND: Endovascular aneurysm repair (EVAR) and open surgical repair (OSR) are two modalities to treat patients with abdominal aortic aneurysm (AAA). Alternative to individual comorbidity adjustment, a summary comorbidity index is a weighted composite score of all comorbidities that can be used as standard metric to control for comorbidity burden in clinical studies. This study aimed to develop summary comorbidity indices for patients who underwent AAA repair. METHODS: Patients who went under EVAR or OSR were identified in National Inpatient Sample (NIS) between the last quarter of 2015 to 2020. In each group, patients were randomly sampled into experimental (2/3) and validation (1/3) groups. The weights of Elixhauser comorbidities were determined from a multivariable logistic regression and single comorbidity indices were developed for EVAR and OAR groups, respectively. RESULTS: There were 34,668 patients underwent EVAR (2.19% mortality) and 4792 underwent OSR (10.98% mortality). Both comorbidity indices had moderate discriminative power (EVAR c-statistic, 0.641; 95% confidence interval [CI], 0.616-0.665; OSR c-statistic, 0.600; 95% CI, 0.563-0.630) and good calibration (EVAR Brier score, 0.021; OSR Brier score, 0.096). The indices had significantly better discriminative power (DeLong P <.001) than the Elixhauser Comorbidity Index (ECI) (EVAR c-statistic, 0.572; 95% CI, 0.546-0.597; OSR c-statistic, 0.502; 95% CI, 0.472-0.533). For internal validation, both indices had similar performance compared with individual comorbidity adjustment (EVAR DeLong P = .650; OSR DeLong P = .431). These indices demonstrated good external validation, exhibiting comparable performance to their respective validation groups (EVAR DeLong P = .891; OSR DeLong P = .757). CONCLUSIONS: ECI, the comorbidity index formulated for the general population, exhibited suboptimal performance in patients who underwent AAA repair. In response, we developed summary comorbidity indices for both EVAR and OSR for AAA repair, which were internally and externally validated. The EVAR and OSR comorbidity indices outperformed the ECI in discriminating in-hospital mortality rates. They can standardize comorbidity measurement for clinical studies in AAA repair, especially for studies with small samples such as single-institute data sources to facilitate replication and comparison of results across studies.

A preoperative supervised exercise program potentially improves long-term survival after elective abdominal aortic aneurysm repair.

OBJECTIVE: A preoperative supervised exercise program (SEP) improves cardiorespiratory fitness and perioperative outcomes for patients undergoing elective abdominal aortic aneurysm (AAA) repair. The aim of this study was to assess the effect of a preoperative SEP on long-term survival of these patients. A secondary aim was to consider long-term changes in cardiorespiratory fitness and quality of life. METHODS: Patients scheduled for open or endovascular AAA repair were previously randomized to either a 6-week preoperative SEP or standard management, and a significant improvement in a composite outcome of cardiac, pulmonary, and renal complications was seen following SEP. For the current analysis, patients were followed up to 5 years post-surgery. The primary outcome for this analysis was all-cause mortality. Data were analyzed on an intention to treat (ITT) and per protocol (PP) basis, with the latter meaning that patients randomized to SEP who did not attend any sessions were excluded. The PP analysis was further interrogated using a complier average causal effect (CACE) analysis on an all or nothing scale, which adjusts for compliance. Additionally, patients who agreed to follow-up attended the research center for cardiopulmonary exercise testing and/or provided quality of life measures. RESULTS: ITT analysis demonstrated that the primary endpoint occurred in 24 of the 124 participants at 5 years, with eight in the SEP group and 16 in the control group (P = .08). The PP analysis demonstrated a significant survival benefit associated with SEP attendance (4 vs 16 deaths; P = .01). CACE analysis confirmed a significant intervention effect (hazard ratio, 0.36; 95% confidence interval, 0.16-0.90; P = .02). There was no difference between groups for cardiorespiratory fitness measures and most quality of life measures. CONCLUSIONS: These novel findings suggest a long-term mortality benefit for patients attending a SEP prior to elective AAA repair. The underlying mechanism remains unknown, and this merits further investigation.

[Consequences of the COVID-19 pandemic for surgical service]. / Posledstviya pandemii COVID-19 dlya khirurgicheskoi sluzhby.

The COVID-19 pandemic has a serious impact on surgical service, emergency and especially elective surgical care. Many hospitals were re-designated as COVID hospitals due to resource constraints and large number of COVID-19 patients requiring hospitalization. This led to cancellation or postponement of scheduled surgeries. In addition, restrictions in elective surgery were associated with the risk of infection in surgical patients. Various protocols and guidelines recommended non-surgical or outpatient treatment if possible. During the pandemic, postoperative morbidity and mortality in emergency surgery increased significantly. The same is true for elective surgeries in 7-8 weeks after previous coronavirus infection. The authors analyze the issues of organization, priorities for restoration of elective surgery and criteria for patient selection.

Empleo de antibióticos en cirugía electiva en el adulto mayor / Antibiotic Use for Elective Surgery in the Older Adult

Objetivo: Determinar el comportamiento del uso de los antibióticos en pacientes geriátricos que requieren cirugía electiva atendidos en el Hospital Vladimir Ilich Lenin del 2018 al 2022. Métodos: Se realizó un estudio descriptivo, observacional, analítico y transversal a pacientes intervenidos por cirugía electiva con tratamiento con antibiótico. Los datos se obtuvieron de las historias clínicas y la entrevista aplicada. Se analizaron variables como edad, sexo, enfermedades asociadas, diagnóstico preoperatorio, tiempo quirúrgico, complicaciones, evolución, filtrado glomerular y dosis antibiótica perioperatoria. Resultados: El empleo de antibióticos fue más utilizado en los grupos de edades de 60 a 64 años y el sexo femenino; las comorbilidades que predominaron fueron la diabetes mellitus, la hipertensión arterial y la cardiopatía isquémica. Los motivos de consulta más frecuentes fueron por litiasis vesicular y por hernias dentro del grupo ASA I de la American Society of Anesthesiologists. Los antibióticos fundamentales fueron con dosis ajustada. Conclusiones: Se necesita de un trabajo diferenciado en cuanto a la atención al adulto mayor. La utilización de un protocolo o algoritmo de trabajo es necesario en la práctica diaria, sobre todo ante la necesidad de una cirugía electiva(AU)

Introduction: Geriatric surgical patients have functional impairment and associated diseases, which increases their surgical risk with age. Objective: To determine the behavior of antibiotic use in geriatric patients requiring elective surgery attended at Hospital Vladimir Ilich Lenin Hospital from 2018 to 2022. Methods: A descriptive, observational, analytical and cross-sectional study was conducted on patients undergoing elective surgery with antibiotic treatment. The data were obtained from medical records and the applied interview. The analyzed variables included age, sex, associated diseases, preoperative diagnosis, surgical time, complications, evolution, glomerular filtration and perioperative antibiotic dose. Results: Antibiotic use was more frequent in the age group 60 to 64 years and in the female sex; the most frequent comorbidities were diabetes mellitus, arterial hypertension and ischemic heart disease. The most frequent reasons for consultation were vesicular lithiasis and hernias within the ASA I group of the American Society of Anesthesiologists. The fundamental antibiotics were adjusted by doses. Conclusions: An individualized work is needed in terms of care of the older adult. The use of a working protocol or algorithm is necessary in daily practice, especially when elective surgery is required(AU)

Day-case and in-patient elective inguinal hernia repair surgery across England: an observational study of variation and outcomes.

PURPOSE: Elective primary inguinal hernia repair surgery is increasingly being conducted as a day-case procedure. However, in England there is evidence of wide variation in day-case rates across hospitals. Reducing the extent of this variation has the potential to support more efficient use of resources (e.g., clinician time, hospital beds) and help the recovery of elective surgical activity following the COVID-19 pandemic. The aims of this study were to explore the extent of variation in day-case rates across healthcare providers in England and to evaluate the safety of day-case elective primary inguinal hernia repair surgery. METHODS: This was an exploratory, retrospective analysis of observational data from the Hospital Episode Statistics data set for England. All patients aged ≥ 17 years undergoing a first elective inguinal hernia repair between 1st April 2014 and 31st March 2022 were identified. The exposure of interest was day-case or in-patient stay, and the primary outcome of interest was 30-day emergency readmission with an overnight stay. For reporting, providers were aggregated to an Integrated Care Board (ICB) level. RESULTS: A total of 413,059 elective primary inguinal hernia repairs were identified over the 8-year study period. Of these, 326,833 (79.1%) were day-case procedures. During the most recent financial year (2021-22), the highest day-case rate for an ICB was 93.8% and the lowest 66.1%. After adjusting for covariates, day-case surgery was associated with significantly lower rates of 30-day emergency readmission (odds ratio (OR) 0.61, 95% confidence interval (CI) 0.58-0.64, p < 0.001) and for the secondary outcomes 180-day mortality and haemorrhage, infection and pain at 30-day post-discharge. Rates of 30-day emergency readmission were significantly lower in ICBs with high rates of day-case surgery (OR 0.84, 95% CI 0.74-0.96, p < 0.001) than in ICBs with low rates of day-case surgery, although rates of post-procedural haemorrhage within 30 days of discharge were significantly higher in trusts with high day-case rates (OR 1.20, 95% CI 1.04-1.40, p = 0.015). CONCLUSIONS: For the outcomes studied, we found no consistent evidence that day-case elective inguinal hernia repair was unsafe for selected patients. Currently, there is substantial variation between ICBs in terms of delivering day-case surgery. Reducing this variability may help address the current pressures on the NHS in elective surgery.

Enhanced perioperative care in emergency general surgery: the WSES position paper.

Enhanced perioperative care protocols become the standard of care in elective surgery with a significant improvement in patients' outcome. The key element of the enhanced perioperative care protocol is the multimodal and interdisciplinary approach targeted to the patient, focused on a holistic approach to reduce surgical stress and improve perioperative recovery. Enhanced perioperative care in emergency general surgery is still a debated topic with little evidence available. The present position paper illustrates the existing evidence about perioperative care in emergency surgery patients with a focus on each perioperative intervention in the preoperative, intraoperative and postoperative phase. For each item was proposed and approved a statement by the WSES collaborative group.

Consensus Guidelines for Perioperative Care for Emergency Laparotomy Enhanced Recovery After Surgery (ERAS®) Society Recommendations Part 2-Emergency Laparotomy: Intra- and Postoperative Care.

BACKGROUND: This is Part 2 of the first consensus guidelines for optimal care of patients undergoing emergency laparotomy (EL) using an Enhanced Recovery After Surgery (ERAS) approach. This paper addresses intra- and postoperative aspects of care. METHODS: Experts in aspects of management of high-risk and emergency general surgical patients were invited to contribute by the International ERAS® Society. PubMed, Cochrane, Embase, and Medline database searches were performed for ERAS elements and relevant specific topics. Studies on each item were selected with particular attention to randomized clinical trials, systematic reviews, meta-analyses, and large cohort studies and reviewed and graded using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Recommendations were made on the best level of evidence, or extrapolation from studies on elective patients when appropriate. A modified Delphi method was used to validate final recommendations. Some ERAS® components covered in other guideline papers are outlined only briefly, with the bulk of the text focusing on key areas pertaining specifically to EL. RESULTS: Twenty-three components of intraoperative and postoperative care were defined. Consensus was reached after three rounds of a modified Delphi Process. CONCLUSIONS: These guidelines are based on best available evidence for an ERAS® approach to patients undergoing EL. These guidelines are not exhaustive but pull together evidence on important components of care for this high-risk patient population. As much of the evidence is extrapolated from elective surgery or emergency general surgery (not specifically laparotomy), many of the components need further evaluation in future studies.

The relationship between computed tomography-derived body composition, systemic inflammation, and survival in patients with abdominal aortic aneurysm.

OBJECTIVE: Patient selection and risk stratification for elective repair of abdominal aortic aneurysm (AAA), either by open surgical repair or by endovascular aneurysm repair, remain challenging. Computed tomography (CT)-derived body composition analysis (CT-BC) and systemic inflammation-based scoring systems such as the systemic inflammatory grade (SIG) appear to offer prognostic value in patients with AAA undergoing endovascular aneurysm repair. The relationship between CT-BC, systemic inflammation, and prognosis has been explored in patients with cancer, but data in noncancer populations are lacking. The present study aimed to examine the relationship between CT-BC, SIG, and survival in patients undergoing elective intervention for AAA. METHODS: A total of 611 consecutive patients who underwent elective intervention for AAA at three large tertiary referral centers were retrospectively recruited for inclusion into the study. CT-BC was performed and analyzed using the CT-derived sarcopenia score (CT-SS). Subcutaneous and visceral fat indices were also recorded. SIG was calculated from preoperative blood tests. The outcomes of interest were overall and 5-year mortality. RESULTS: Median (interquartile range) follow-up was 67.0 (32) months, and there were 194 (32%) deaths during the follow-up period. There were 122 (20%) open surgical repair cases, 558 (91%) patients were male, and the median (interquartile range) age was 73.0 (11.0) years. Age (hazard ratio [HR]: 1.66, 95% confidence interval [CI]: 1.28-2.14, P < .001), elevated CT-SS (HR: 1.58, 95% CI: 1.28-1.94, P < .001), and elevated SIG (HR: 1.29, 95% CI: 1.07-1.55, P < .01) were independently associated with increased hazard of mortality. Mean (95% CI) survival in the CT-SS 0 and SIG 0 subgroup was 92.6 (84.8-100.4) months compared with 44.9 (30.6-59.2) months in the CT-SS 2 and SIG ≥2 subgroup (P < .001). Patients with CT-SS 0 and SIG 0 had 90% (standard error: 4%) 5-year survival compared with 34% (standard error: 9%) in patients with CT-SS 2 and SIG ≥2 (P < .001). CONCLUSIONS: Combining measures of radiological sarcopenia and the systemic inflammatory response offers prognostic value in patients undergoing elective intervention for AAA and may contribute to future clinical risk predication strategies.

[Features of surgical patients of COVID-19 patients]. / Osobennosti khirurgicheskogo lecheniya bol'nykh COVID-19.

The novel coronavirus pandemic has significantly increased the workload of surgical service worldwide. Restrictive measures led to postponement of elective surgical and diagnostic interventions and reduced the number of emergency manipulations around the world. Large-scale studies identified optimal period for postponing surgical procedures and advisability of this postponement. The authors present opinions of surgeons and their views on treatment strategy for various elective and emergency surgical interventions in abdominal surgery, traumatology-orthopedics and oncology. The main factors reducing perioperative mortality in patients with a new coronavirus infection are observance of anti-epidemic measures by patients and medical personnel, competent use of personal protective equipment, as well as adherence to protocols and algorithms for the treatment of these patients.

Thirty-day mortality in females after elective and urgent abdominal aortic aneurysm repair.

INTRODUCTION: Female sex is a risk factor of post-operative mortality and morbidity after abdominal aortic aneurysm (AAA) repair. The aim of this systematic review is to assess the sex-specific early mortality following both elective and urgent AAA repair. EVIDENCE ACQUISITION: The Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed. Observational studies (2000-2022), of the English medical literature, focusing on early mortality after AAA repair in females under elective or urgent setting were eligible. A systematic search of MEDLINE, EMBASE and CENTRAL databases, was conducted (November 30th, 2022). The risk of bias was assessed using the Newcastle-Ottawa Scale. Primary outcome was 30-day mortality in relevant strata. A proportional metanalysis was used to assess the estimates. EVIDENCE SYNTHESIS: Seventeen retrospective studies and 83,738 females were included. Thereof 68.7% underwent elective repair while the remaining were managed urgently. Endovascular repair (EVAR) was applied in 37.3% of patients (15.4% urgent) vs. 62.7% with OSR (23.5% urgent). In the total cohort, the perioperative mortality was estimated at 11% (OR, 95% CI: 5-17%, P<0.01, I2 99.92%) while 3% (OR, 95% CI: 0.02-0.03, P<0.01, I2 93.42%) deceased after elective repair (2% OR, 95% CI 0.01-0.02, P<0.01, I2 83.08%, after EVAR and 5% (OR, 95% CI: 0.05-0.06, P<0.01, I2 77.36%, after OSR) and 36% (OR, 95% CI: 0.28-0.44, P<0.01, I2 99.51%) after urgent repair (25% OR, 95% CI: 0.16-0.34, P<0.01, I2 98.45%, after EVAR and 40% (OR, 95% CI: 0.34-0.46, P<0.01, I2 95.96%, after OSR). CONCLUSIONS: AAA repair in females appears to be associated with considerable postoperative mortality. Despite the rapid development of innovative techniques and intensive care of severely ill patients, perioperative mortality after ruptured AAA remains devastatingly high.

Immune Phenotype and Postoperative Complications After Elective Surgery.

OBJECTIVES: To characterize and quantify accumulating immunologic alterations, pre and postoperatively in patients undergoing elective surgical procedures. BACKGROUND: Elective surgery is an anticipatable, controlled human injury. Although the human response to injury is generally stereotyped, individual variability exists. This makes surgical outcomes less predictable, even after standardized procedures, and may provoke complications in patients unable to compensate for their injury. One potential source of variation is found in immune cell maturation, with phenotypic changes dependent on an individual's unique, lifelong response to environmental antigens. METHODS: We enrolled 248 patients in a prospective trial facilitating comprehensive biospecimen and clinical data collection in patients scheduled to undergo elective surgery. Peripheral blood was collected preoperatively, and immediately on return to the postanesthesia care unit. Postoperative complications that occurred within 30 days after surgery were captured. RESULTS: As this was an elective surgical cohort, outcomes were generally favorable. With a median follow-up of 6 months, the overall survival at 30 days was 100%. However, 20.5% of the cohort experienced a postoperative complication (infection, readmission, or system dysfunction). We identified substantial heterogeneity of immune senescence and terminal differentiation phenotypes in surgical patients. More importantly, phenotypes indicating increased T-cell maturation and senescence were associated with postoperative complications and were evident preoperatively. CONCLUSIONS: The baseline immune repertoire may define an immune signature of resilience to surgical injury and help predict risk for surgical complications.
