Meckel's Diverticulum Causing Ileal Volvulus and Peritonitis after a Recent Appendectomy: A Case Report and Literature Review-We Should Likely Resect an Incidental MD. Life (Basel) 2023; 13:1996. [PMID: 37895380 PMCID: PMC10608533 DOI: 10.3390/life13101996] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 09/24/2023] [Accepted: 09/27/2023] [Indexed: 10/29/2023] Open
Abstract
Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract with a 1-3% prevalence in the general population. The surgical management of symptomatic MD is well described in the literature, but there is still no consensus on the indication for prophylactic resection of incidental asymptomatic MD. To address this issue, we extensively reviewed the current literature and report our experience with laparoscopic management of an unusual case of MD causing ileal volvulus and acute peritonitis two weeks after a laparoscopic appendectomy for acute gangrenous appendicitis performed in another hospital. A 50-year-old man presented to the emergency department with acute and severe abdominal pain, vomiting, and constipation. He had undergone a laparoscopic appendectomy for acute appendicitis two weeks before in another hospital. The patient was apyretic, distressed, and seeking an antalgic position. The abdomen was mildly distended and tender, and the Blumberg sign was mildly positive in the central quadrants. The clinical picture deteriorated with fever, peritonismus, and leukocytosis. A CT scan showed an ileo-ileal adhesion near the ileocolic junction and dilatation of the upstream loops with the air-fluid levels. Through an urgent laparoscopy, a necrotic mass, the MD, was wedge-resected, and the surrounding ileal volvulus derotated. The postoperative course was uneventful. There is no definitive consensus on the appropriate management of incidental asymptomatic MD, although several studies have attempted to identify guiding criteria. Features of the MD, the patient's risk factors, clinical presentation, and surgical approach need to be considered to establish definitive guidelines for the management of incidental asymptomatic MD. In the absence of definitive guidelines, personal expertise and judgement are the main resources for the surgeon approaching an incidental asymptomatic MD.

The Impact of the COVID-19 Pandemic on Surgical Services in Brazil's Healthcare System: A Retrospective Cross-Sectional Study. Cureus 2023; 15:e44693. [PMID: 37809122 PMCID: PMC10551661 DOI: 10.7759/cureus.44693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/04/2023] [Indexed: 10/10/2023] Open
Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic provoked disruptions in healthcare delivery, leading to the cancellation and postponement of various health services, including surgery. Numerous countries closed their borders and established laws mandating the use of face masks and social distancing and enforced lockdowns, and various activities were constrained. Brazil, the largest and most populous country in Latin America, also experienced a rapid and sustained surge in infections and deaths. Brazil was the most severely impacted nation in Latin America. The impact of the pandemic on surgical services in Brazil has not been adequately studied since most studies only cover the early phases of the pandemic. Thus, this study aimed to assess the impact of the COVID-19 pandemic on surgical services throughout the entire period. Methods A retrospective cross-sectional design was used to examine surgical cases from 2019 to 2022 and compared the following indicators: (1) number of hospital admissions, (2) length of hospital stay (LOS) (in days), and (3) volume of urgent and elective procedures. Data was divided into four time periods, pre-pandemic (March-December 2019), pandemic (March-December 2020), recovery (March-December 2021), and post-pandemic (March-December 2022), and was analyzed for the number of admissions and LOS based on surgical procedures performed by stratifying according to region, sex, age, and type of surgery (urgent versus elective). Results The number of admissions for surgical procedures ranged between 859,646 and 4,015,624 for 2019, 686,616 and 3,419,234 for 2020, 787,791 and 3,829,019 for 2021, and 760,512 and 3,857,817 for 2022 for the category of region; 4,260,900 and 5,991,775 for 2019, 3,594,117 and 4,984,710 for 2020, 4,182,640 and 5,590,808 for 2021, and 4,077,651 and 5,561,928 for 2022 for the category of sex; and 2,170,288 and 3,186,117 for 2019, 1,516,830 and 2,825,189 for 2020, 1,748,202 and 3,030,272 for 2021, and 1,900,023 and 2,859,179 for 2022 for the category of age. The variable age showed a comparable trend, albeit with an expressive decline for surgeries in the age range of 0-19 years. The LOS (in days) for surgical procedures ranged between 110,157 and 910,846 for 2019, 58,562 and 897,734 for 2020, 67,926 and 904,137 for 2021, and 100,467 and 823,545 for 2022. Thoracic surgery indicated no statistically significant difference in the number of admissions and LOS. Elective surgeries had a decline in the number of admissions and LOS, a 13% and 9.3% decline between 2019 and 2020, respectively. Urgent surgeries experienced a slight decrease in admissions and LOS, with a decline of 2.4% and 2.8% between 2019 and 2020, respectively. Conclusions Population characteristics, such as age, sex, and region, showed decreased hospital admissions during the pandemic, followed by a recovery toward pre-pandemic levels afterward. The number of surgical admissions and the length of hospital stays decreased during the pandemic but gradually returned to pre-pandemic levels in the recovery and post-pandemic phases. Notably, thoracic surgery remained statistically consistent across all periods, indicating its emergency nature compared to other surgeries. Thus, we conclude that the pandemic had minimal impact on thoracic surgery cases, contributing to a stable trend.

Abstract
INTRODUCTION Attendance of patients to the emergency department due to acute large bowel obstruction is a common phenomenon. Most of these patients are elderly, critically ill, and with high comorbidity. The literature suggests that more than 50% of these cases are due to colon cancer. Since this condition is considered to be an emergency, immediate intervention and response is imperative. PURPOSE The aim of the present study is to present our surgical technique of colostomy formation under local anesthesia in selected critically ill patients, with increased perioperative risk and acute large bowel obstruction. MATERIALS AND METHODS This is a retrospective study of 24 patients, with obstipation, who underwent emergency colostomy under local anesthesia, during the period from 2014 to 2021. RESULTS The mean age of the patients was 77 years. The vast majority of patients had an American Society of Anesthesiologists (ASA) score of ≥3 and a Charlson score of ≥7. The most common colostomy was transverse colostomy (21/24 patients). The patients' hospitalization ranged from four to 42 days. Only one patient died. All colostomies functioned properly in the immediate postoperative period. Only one patient required postoperative admission to the ICU. CONCLUSIONS Colostomy under local anesthesia in critically ill, elderly patients is an alternative option for the treatment of ileus.

Machine learning-based prediction of postoperative mortality in emergency colorectal surgery: A retrospective, multicenter cohort study using Tokushukai medical database. Heliyon 2023; 9:e19695. [PMID: 37810013 PMCID: PMC10558952 DOI: 10.1016/j.heliyon.2023.e19695] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 08/29/2023] [Accepted: 08/30/2023] [Indexed: 10/10/2023] Open
Abstract
Background Although prognostic factors associated with mortality in patients with emergency colorectal surgery have been identified, an accurate mortality risk assessment is still necessary to determine the range of therapeutic resources in accordance with the severity of patients. We established machine-learning models to predict in-hospital mortality for patients who had emergency colorectal surgery using clinical data at admission and attempted to identify prognostic factors associated with in-hospital mortality. Methods This retrospective cohort study included adult patients undergoing emergency colorectal surgery in 42 hospitals between 2012 and 2020. We employed logistic regression and three supervised machine-learning models: random forests, gradient-boosting decision trees (GBDT), and multilayer perceptron (MLP). The area under the receiver operating characteristics curve (AUROC) was calculated for each model. The Shapley additive explanations (SHAP) values are also calculated to identify the significant variables in GBDT. Results There were 8792 patients who underwent emergency colorectal surgery. As a result, the AUROC values of 0.742, 0.782, 0.814, and 0.768 were obtained for logistic regression, random forests, GBDT, and MLP. According to SHAP values, age, colorectal cancer, use of laparoscopy, and some laboratory variables, including serum lactate dehydrogenase serum albumin, and blood urea nitrogen, were significantly associated with in-hospital mortality. Conclusion We successfully generated a machine-learning prediction model, including GBDT, with the best prediction performance and exploited the potential for use in evaluating in-hospital mortality risk for patients who undergo emergency colorectal surgery.

A simulation study and an evaluation of emergency surgery. HEALTH ECONOMICS 2023; 32:2113-2126.

Abstract
Local instrumental variable (LIV) approaches use continuous/multi-valued instrumental variables (IV) to generate consistent estimates of average treatment effects (ATEs) and Conditional Average Treatment Effects (CATEs). There is little evidence on how LIV approaches perform according to the strength of the IV or with different sample sizes. Our simulation study examined the performance of an LIV method, and a two-stage least squares (2SLS) approach across different sample sizes and IV strengths. We considered four 'heterogeneity' scenarios: homogeneity, overt heterogeneity (over measured covariates), essential heterogeneity (unmeasured), and overt and essential heterogeneity combined. In all scenarios, LIV reported estimates with low bias even with the smallest sample size, provided that the instrument was strong. Compared to 2SLS, LIV provided estimates for ATE and CATE with lower levels of bias and Root Mean Squared Error. With smaller sample sizes, both approaches required stronger IVs to ensure low bias. We considered both methods in evaluating emergency surgery (ES) for three acute gastrointestinal conditions. Whereas 2SLS found no differences in the effectiveness of ES according to subgroup, LIV reported that frailer patients had worse outcomes following ES. In settings with continuous IVs of moderate strength, LIV approaches are better suited than 2SLS to estimate policy-relevant treatment effect parameters.

Abstract
Acute carpal tunnel syndrome (ACTS) is an urgent condition in which symptoms progress rapidly on an hourly basis, and emergency surgery may be required to treat it. ACTS often occurs after a traumatic event such as a fracture of the distal radius, and rarely occurs non-traumatically. We present a case of a 60-year-old male with ACTS secondary to acute synovitis due to rheumatoid arthritis. The patient complained of strong numbness from the thumb to the ring finger and pain in the palm, and he was unable to actively flex or extend his fingers. In addition, severe tenderness was observed in the palm; on the contralateral side, no obvious tenderness of the forearm and wrist joint was observed. Due to the intolerable pain and numbness, ACTS was suspected. Internal pressure from the forearm to the palm was measured, and it was found that the internal pressure of the carpal tunnel was elevated at 150 mmHg. Based on these findings, non-traumatic ACTS was diagnosed, and emergency surgery was performed. The transverse carpal ligament was exposed, an incision was made from the distal end, and the proximal part was fully incised to the forearm fascia so that the carpal tunnel was completely released. The synovial membranes around the median nerve were peeled off, confirming that the nerve had been loosened sufficiently. After the operation, finger pain and numbness improved dramatically from the day after surgery. Proper diagnosis and prompt treatment with surgical median nerve decompression are crucial for good functional recovery in these patients.

Abstract
A splenic abscess (SA) following sleeve gastrectomy (SG) is a rare manifestation of a gastric leak (GL). The clinical findings include fever, abdominal pain, leukocytosis, and an elevated C-reactive protein. A computed tomography scan is diagnostic and can show signs of GL, or diffuse peritonitis. Treatment can either be non-operative (including large-spectrum antibiotics and percutaneous drainage) or surgical (including splenectomy). We present the case of a 41-year-old female patient with SA, with septic shock and diffuse peritonitis, successfully treated with a splenectomy three months post-SG.

Abstract
During our practice as clinical surgeons, we have encountered situations in which exploratory abdominal laparotomies have yielded unexpected outcomes, despite conducting thorough and rigorous preoperative studies. A rare condition called sclerosing encapsulating peritonitis (SEP), in which a fibrocollagenous membrane encircles the intestine and other abdominal organs, surprised us in a case of an acute abdomen. Persistent descending mesocolon is another unusual condition in which the descending colon is transferred downward and to the right abdominal region because its mesocolon is unable to merge with the posterior abdominal wall. Those two different conditions are extremely rare and were never been described in a single case. We present a case of an 80-year-old male who presented in the emergency department with an acute abdomen and puzzled us.

Abstract
BACKGROUND/AIM Determination of risk factors for stoma-related complications associated with emergency stoma creation may impact on reducing complications and improving the quality of life of ostomy patients; however, there are only few reports on stoma-related complications associated with emergency stoma creation. Our study aimed to identify risk factors associated with stoma-related complications after emergency surgery, and evaluate surgical techniques for good stoma creation in the emergency setting. PATIENTS AND METHODS A retrospective analysis of patient and surgical characteristics was performed in 104 consecutive patients who underwent ileostomy or colostomy as emergency surgery between January 2020 and December 2022 at the Gunma University Hospital. RESULTS Preoperative stoma site marking was performed in 70 (67.3%) patients. Colostomies and ileostomies were performed in 78 (75.0%) and 26 (25.0%) patients, respectively. The skin bridge technique was used in 13 (12.5%) patients. Stoma-related complications were diagnosed in 62 (59.6 %) patients, with peristomal skin disorders (47.1%) as the most common complication, followed by mucocutaneous separation (31.7%), and stoma retraction (19.2%). In the multivariate analysis, body mass index (BMI) [odds ratio (OR)=5.570, 95% confidence interval (CI)=1.233-25.167, p=0.026], skin bridge technique (OR=0.144, 95% CI=0.031-0.670, p=0.014), and stoma height (OR=0.134, 95% CI=0.038-0.469, p=0.002) were independent risk factors for stoma-related complications after emergency stoma creation. CONCLUSION In emergency stoma creation, higher BMI and lower stoma height are associated with stoma-related complications. Using the skin bridge technique could reduce the risk of stoma-related complications after emergency stoma creation.

Abstract
AIM Emergency laparotomy and laparoscopy (EmLap) are amongst the commonest surgical procedures, with high prevalence of sepsis and hence poorer outcomes. However, whether time taken to receive care influences outcomes in patients requiring antibiotics for suspected infection remains largely unexplored. The aim of this work was to determine whether (1) time to care contributes to outcome differences between patients with and without suspected infection and (2) its impact on outcomes only amongst those with suspected infection. METHOD Clinical information was retrospectively obtained from the 2017-2018 Emergency Laparotomy and Laparoscopic Scottish Audit (ELLSA). Time to care referred to six temporal variables describing radiological investigation, anaesthetic triage and surgical management. Outcome measures [mortality, readmission, hospital death, postoperative destination and length of stay (LoS)] were compared using adjusted and unadjusted regression analyses to determine whether the outcome differences could be explained by faster or slower time to care. RESULTS Amongst 2243 EmLap patients [median age 65 years (interquartile range 51-75 years), 51.1% female], 892 (39.77%) received antibiotics for suspected infection. Although patients with suspected infection had faster time to care (all p ≤ 0.001) and worse outcomes compared with those who did not, outcome differences were not statistically significant when accounted for time (all p > 0.050). Amongst those who received antibiotics, faster time to care was also associated with decreased risk of postoperative intensive care unit (ICU) stay and shorter LoS (all p < 0.050). CONCLUSION Worse outcomes associated with infection in EmLap patients were attenuated by faster time to care, which additionally reduced the LoS and ICU stay risk amongst those with suspected infection.

Abstract
Antibiotic therapy following surgical perianal abscess drainage is debated, but may be necessary for high-risk patients. Frailty has been shown to increase the risk of unfavorable outcomes in elderly surgical patients. This study aims to identify high-risk patients by retrospectively analyzing a single-center cohort and using a pretherapeutic score to predict the need for postoperative antibiotics and extended nursing care following perianal abscess drainage surgery. The perianal sepsis risk score was developed through univariable and multivariable analysis. Internal validation was assessed using the area under receiver-operating characteristic curve. Elderly, especially frail patients exhibited more severe perianal disease, higher frequency of antibiotic therapy, longer hospitalization, poorer clinical outcomes. Multivariable analysis revealed that scores in the 5-item modified frailty index, severity of local infection, and preoperative laboratory markers of infection independently predicted the need for prolonged hospitalization and anti-infective therapy after abscess drainage surgery. These factors were combined into the perianal sepsis risk score, which demonstrated better predictive accuracy for prolonged hospitalization and antibiotic therapy compared with chronological age or frailty status alone. Geriatric assessments are becoming increasingly important in clinical practice. The perianal sepsis risk score identifies high-risk patients before surgery, enabling early initiation of antibiotic therapy and allocation of additional nursing resources.

Abstract
The coronavirus disease-2019 (COVID-19) pandemic has placed many restrictions on medical care. The timing of surgical treatment has been particularly affected, with patients experiencing delayed operation dates. This report describes three patients with preoperative COVID-19-positive diagnoses, tested with reverse transcription-polymerase chain reaction, who were urgently treated surgically with excellent results. Case 1 involved an 89-year-old woman with a left ventricular rupture after a myocardial infarction. Case 2 involved a 52-year-old male patient with an acute type A aortic dissection. Case 3 involved a patient with an occlusion of an autologous dialysis shunt. All patient conditions were either life-threatening or overwhelmed hospital beds without surgical treatment. In Japan, we still experience cases where surgery is refused because of COVID-19 positivity, even if emergency surgery is necessary. This report describes three cases where standard precautions were taken, postoperative management was devised, and good results were achieved.

Abstract
OBJECTIVES International health technology assessment (HTA) agencies recommend that real-world data (RWD) are used in some circumstances to add to the evidence base about the effectiveness and cost-effectiveness of health interventions. The target trial framework applies the design principles of randomized-controlled trials to RWD and can help alleviate inevitable concerns about bias and design flaws with nonrandomized studies. This article aimed to tackle the lack of guidance and exemplar applications on how this methodology can be applied to RWD to inform HTA decision making. METHODS We use Hospital Episode Statistics data from England on emergency hospital admissions from 2010 to 2019 to evaluate the cost-effectiveness of emergency surgery for 2 acute gastrointestinal conditions. We draw on the case study to describe the main challenges in applying the target trial framework alongside RWD and provide recommendations for how these can be addressed in practice. RESULTS The 4 main challenges when applying the target trial framework to RWD are (1) defining the study population, (2) defining the treatment strategies, (3) establishing time zero (baseline), and (4) adjusting for unmeasured confounding. The recommendations for how to address these challenges, mainly around the incorporation of expert judgment and use of appropriate methods for handling unmeasured confounding, are illustrated within the case study. CONCLUSIONS The recommendations outlined in this study could help future studies seeking to inform HTA decision processes. These recommendations can complement checklists for economic evaluations and design tools for estimating treatment effectiveness in nonrandomized studies.

Abstract
BACKGROUND Recent studies suggest that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection increases the incidence of postoperative pulmonary complications (PPCs) and mortality. Consequently, patients with SARS-CoV-2 infection undergoing emergency surgery are more vulnerable to PPCs, yet few studies have evaluated PPCs in these patients. METHODS A retrospective analysis was conducted between January 2022 and February 2023 on the medical records of patients infected with SARS-CoV-2 who underwent emergency surgery. The study evaluated the incidence of PPCs and 30-day postoperative mortality in all enrolled patients. RESULTS A total of 41 patients were enrolled, among whom PPCs occurred in seven patients (17%). The incidence of PPCs was statistically significant in patients with underlying diabetes compared to those without (p = 0.01) and in patients with an American Society of Anesthesiologists (ASA) class 3 or higher compared to those with less than 3 (p = 0.005) (ASA classification uses a grading system of I (one) through V (five)). The 30-day mortality rate was 4.9%. CONCLUSIONS Our study demonstrates that the incidence of PPCs and 30-day mortality rates after emergency surgery in patients infected with SARS-CoV-2 are higher compared to prepandemic baseline rates. Given the significant interest and concern worldwide regarding severe infectious respiratory diseases, such as coronavirus disease 2019 (COVID-19), clinicians should focus on conducting research to identify ways to reduce the incidence of PPCs and mortality in patients with severe acute respiratory infections.

Abstract
BACKGROUND Spinal injuries, whether mechanical or neurological, frequently require urgent intervention. Superior outcomes are associated with earlier intervention, which often requires operating overnight and on weekends. However, operating after hours has been associated with increased risks of complications in selected studies. The authors sought to determine whether there are differences in outcomes for "after hours" surgery compared with "during hours" surgery for spinal emergencies. METHODS This is a single-center retrospective cohort study of spine surgery patients who underwent urgent surgery within 6 hours, from January 2015 through December 2019. Surgery was considered during hours if it started between 8 am and 5 pm Monday through Friday. After hours was defined as from 5 pm through 8 am on a weekday or Saturday or Sunday. We assessed 30-day outcome measures for differences between operations performed during hours or after hours. RESULTS There were 241 spine procedures performed (49 during hours and 192 after hours). There was no significant difference between the length of operation (145.3 vs 129.8 minutes, P = 0.29), estimated blood loss (303.9 vs 274.4 mL, P = 0.61), improvement in American Spinal Injury Association scale (0.26 vs 0.24 grade, P = 0.85), 30-day return to the operating room (OR; 14.3% vs 6.8%, P = 0.09), 30-day readmission (2.0% vs 6.3% P = 0.24), intensive care unit length of stay (4.6 vs 6.3 days, P = 0.27), hospital length of stay (13.5 days vs 14.2 days, P = 0.72), or 30-day mortality (4.1% vs 7.3%, P = 0.42) for cases performed during hours compared with those after hours, respectively. On multivariate analysis, prior malignancy (P = 0.008) and blue immediate status (P = 0.004) were predictors of 30-day mortality. However, "after hours" surgery was not a predictor of 30-day return to the OR, readmission, or mortality in either univariate or multivariate analysis. CONCLUSIONS Spine surgery must often be performed after hours. However, the time of day does not significantly impact the 30-day outcomes for emergent spine surgery. LEVEL OF EVIDENCE: 3

Abstract
The broad uptake of the acute surgical unit (ASU) model of surgical care in Australia has resulted in general surgeons becoming increasingly involved in the management of patients with acute abdominal pain (AAP), some of whom will be labelled as having non-specific abdominal pain (NSAP) (Kinnear N, Jolly S, Herath M, et al. The acute surgical unit: An updated systematic review and meta-analysis. review. Int. J. Surg. 2021;94:106109; Lehane CW, Jootun RN, Bennett M, Wong S, Truskett P. Does an acute care surgical model improve the management and outcome of acute cholecystitis? ANZ J. Surg. 2010;80:438-42). NSAP patients lack a clear diagnosis of surgical pathology based on standard clinical, laboratory and imaging work-up, although they may require ASU admission for pain control and assessment. This article provides a review of uncommon conditions, presenting as AAP, that could possibly be mis-labelled as NSAP, with a focus on aspects of the presentation that may aid diagnosis and management including specific demographic features, clinical findings, key investigations and initial treatment priorities for ASU clinicians. Ultimately, most of the conditions discussed will not require surgical intervention, however, they require a diagnosis to be made and initial treatment planning before on-referral to the appropriate specialty. For the on-call general surgeon, some knowledge of these conditions and an index of suspicion are invaluable for the prompt diagnosis and efficient management of these patients.

Abstract
BACKGROUND This systematic review and meta-analysis seeks to assess the modified protocols used and patient outcomes when enhanced recovery after surgery (ERAS) protocols are utilized in an emergency setting. METHODS PubMed, MEDLINE, EMBASE and Cochrane Central Registry of Controlled Trials were comprehensively searched until 13 March 2023. The Cochrane Risk of Bias Assessment Tool was used to assess for bias, along with funnel plot asymmetry. We present log risk ratios for dichotomous variables and raw mean differences for continuous variables. RESULTS Seven randomized trials were included, comprising 573 patients. Results of the primary outcomes when comparing ERAS to standard care are as follows; withdrawal of nasogastric tube (raw mean difference -1.87 CI: -2.386 to -1.359), time to first liquid diet (raw mean difference -2.56 CI: -3.435 to -1.669), time to first solid diet (raw mean difference -2.35 CI: -2.933 to -1.76), time to first flatus (raw mean difference -2.73 CI: -5.726 to 0.257), time to first stool passed (raw mean difference -1.83 CI: -2.307 to -1.349), time to removal of drains (raw mean difference -3.23 CI: -3.609 to -2.852), time to removal of urinary catheter (raw mean difference -1.57 CI: -3.472 to 0.334), mean pain score (raw mean difference -1.79 CI: -2.222 to -1.351) and length of hospital stay (raw mean difference -3.16 CI: -3.688 to -2.63). CONCLUSIONS The adoption of ERAS protocols in an emergency surgery setting was observed to enhance patient recovery, while not indicating any statistically significant increase in adverse outcomes.

Abstract
There is currently no consensus or homogeneous recommendation about the role of the laparoscopic approach in emergent inguinal hernia surgery. The aim of this manuscript is showing our experience and results of laparoscopic approach for emergent groin hernia repair comparing with open approach. A retrospective review of a prospectively maintained database between January 2011 and December 2021 of acute incarcerated groin hernia that were operated at Virgen del Rocio University Hospital. In this period, they were identified 463 patients with groin hernia that required an emergency repair. 454 patients underwent open surgery (group 1) and 36 patients underwent laparoscopic approach (TAPP procedure) (group 2). Median length stay was 1 day in lap group and 2 days in open approach. Reintervention was necessary in 20 cases (4.40%) from group 1 and one (2.27%) from group 2. In laparoscopic approach, no mortality was described but in open approach, 10 patients (2.20%) died. Globally, 58 cases (12.77%) from group 1 and six patients (16.66%) from group 2 presented any complication. Wound infection was higher in group of open repairs (5.94% vs. 2.77%). Non-surgical complications were higher in open approach (19 vs. 0). There is no statistical significance in any of these items. Laparoscopic approach is a safe, feasible and effective therapeutic option for the treatment of incarcerated groin hernia that require emergency surgery, but prospective and randomized comparative studies are needed to establish the best approach.

Abstract
Background A scoping review of literature about the informed consent process for emergency surgery from the perspectives of the patients, next of kin, emergency staff, and available guiding policies. Objectives To provide an overview of the informed consent process for emergency surgery; the challenges that arise from the perspectives of the patients, emergency staff, and next of kin; policies that guide informed consent for emergency surgery; and to identify any knowledge gaps that could guide further inquiry in this area. Methods We searched Google Scholar, PubMed/MEDLINE databases as well as Sheridan Libraries and Welch Medical Library from 1990 to 2021. We included journal articles published in English and excluded non-peer-reviewed journal articles, unpublished manuscripts, and conference abstracts. The themes explored were emergency surgery consent, ethical and theoretical concepts, stakeholders' perceptions, challenges, and policies on emergency surgery. Articles were reviewed by three independent reviewers for relevance. Results Of the 65 articles retrieved, 18 articles were included. Of the 18 articles reviewed, 5 addressed emergency informed consent, 9 stakeholders' perspectives, 7 the challenges of emergency informed consent, 3 ethical and theoretical concepts of emergency informed consent, and 3 articles addressed policies of emergency surgery informed consent. Conclusion There is poor satisfaction in the informed consent process in emergency surgery. Impaired capacity to consent and limited time are a challenge. Policies recommend that informed consent should not delay life-saving emergency care and patient's best interests must be upheld.

Abstract
Intestinal duplication is a rare congenital malformation that can occur in any segment of the digestive tract. It is most commonly found in the ileum of infants and is rarely reported in adults, especially in the colon. Diagnosing intestinal duplication can be extremely challenging due to its diverse clinical manifestations and complex anatomical structure. Surgical intervention is currently considered the mainstay of treatment. In this report, we presented a case of giant duplication of the transverse colon in an adult.

Abstract
Introduction: The number of surgeries for groin hernia (GH) among the elderly follows the increase in life expectancy of the population. The greater number and severity of comorbidities in this group increases the surgical risk, promoting discussion regarding the indication of elective surgery and the benefits of watchful waiting approach (WWA). The aim of the present study was to evaluate the outcomes of emergency hernia surgery among the elderly population. Materials and methods: A systematic review was performed in Pubmed and Scielo databases for the past early 10 years, until July 2022. The subject was groin hernia in the emergency setting focusing the elderly population. The PRISMA statement was followed and the classification of elderly was based on the World Health Organization's definition. Results: A total of 1,037 results were returned and we ended with nine original articles with emphasis in groin hernia in the emergency among the elderly population. In these subjects, the complications rate ranged between 21.2% and 28.9% and the mortality rate ranged between 1.2% and 6%. Cardiopulmonary disease, high ASA and Charlson's scales were associated with greater risk of complications and death. Conclusion: Emergency GH surgery in the elderly population carries an increased risk of complications and mortality. GH surgery is safe or, at least, less harmful when done electively. The risk and benefits of WWA and upfront surgery needs to be assessed and exposed to the patients. Our review sugest that elective surgery should be the option over WWA in this patient population.

Abstract
BACKGROUND The COVID-19 pandemic brought rapid and major changes to research, and those wishing to carry out Patient and Public Involvement (PPI) activities faced challenges, such as restrictions on movement and contact, illness, bereavement and risks to potential participants. Some researchers moved PPI to online settings during this time but remote consultations raise, as well as address, a number of challenges. It is important to learn from PPI undertaken in this period as face-to-face consultation may no longer be the dominant method for PPI. METHODS UK stay-at-home measures announced in March 2020 necessitated immediate revisions to the intended face-to-face methods of PPI consultation for the ESORT Study, which evaluated emergency surgery for patients with common acute conditions. PPI plans and methods were modified to all components being online. We describe and reflect on: initial plans and adaptation; recruitment; training and preparation; implementation, contextualisation and interpretation. Through first-hand accounts we show how the PPI processes were developed, experienced and viewed by different partners in the process. DISCUSSION AND CONCLUSIONS While concerns have been expressed about the possible limiting effects of forgoing face-to-face contact with PPI partners, we found important benefits from the altered dynamic of the online PPI environment. There were increased opportunities for participation which might encourage the involvement of a broader demographic, and unexpected benefits in that the online platform seemed to have a 'democratising' effect on the meetings, to the benefit of the PPI processes and outcomes. Other studies may however find that their particular research context raises particular challenges for the use of online methods, especially in relation to representation and inclusion, as new barriers to participation may be raised. It is important that methodological challenges are addressed, and researchers provide detailed examples of novel methods for discussion and empirical study. PATIENT AND PUBLIC CONTRIBUTION We report a process which involved people with lived experience of emergency conditions and members of the public. A patient member was involved in the design and implementation, and two patients with lived experience contributed to the manuscript.

Abstract
Background On March 9, 2020, the Italian Prime Minister announced the lockdown, which was officially closed on May 4. This extraordinary measure was necessary to contain the COVID-19 pandemic spread in Italy. During this phase, a significant decrease in patients' access to Emergency Department (ED) was observed. Delayed access to treatment determined a delay in the diagnosis of acute surgical conditions, as already documented in other clinical areas, with consequences on surgical outcome and survival. Aim of this study is to provide a detailed description of abdominal urgent-emergent conditions surgically treated and surgical outcomes during the lockdown in a tertiary referral Italian hospital, compared with historical data. Methods A retrospective review of urgent-emergent patients surgically treated in our department was conducted in order to compare patients' characteristics and surgical outcomes during the period March 9th-May 4th, 2020 with the same period of the previous year. Results 152 patients were included in our study, 79 patients in 2020 group and 77 patients in 2019. We found no significant differences between the groups regarding ASA score, age, gender, and disease prevalence. Significant differences were found in symptom duration before ER access and abdominal pain as the main symptom in non-traumatic conditions. We also performed a sub-analysis on peritonitis which showed significant differences in: hospital length of stay, presence of colostomy vs. ileostomy, and fatal events in 2020. No differences were found in the use of laparoscopy. Conclusions While the overall number of ER accesses has decreased in 2020 group, the number of patients surgically treated in emergency-urgency conditions has not decreased. However, those patients waited significantly more before the hospital access. This diagnostic delay was associated with a more severe clinical condition and a consequent significantly worse prognosis.

Abstract
OBJECTIVES This study aims to investigate whether surgery performed during night compared with daytime were associated with an increased risk of operative mortality of type A aortic dissection (TAAD) patients. METHODS A total of 2015 TAAD patients who underwent surgical repair were collected from two cardiovascular centers from Jan 2015 to Jan 2021. According to the start time of surgery, patients were divided into daytime group (06:01 a.m. to 06:00 p.m.) and night-time group (06:01 p.m. to 06:00 a.m.), and retrospective analyses were performed between them. RESULTS The operative mortality of night-time group (12.2%, 43/352) was dramatically higher than daytime group (6.9%, 115/1663; p = 0.001). There was significant difference between night-time and daytime groups in terms of 30-days mortality (5.8% vs 10.8%; p = 0.001) and in-hospital mortality (3.5% vs 6.0%; p = 0.03). The night-time group had a longer duration of intensive care unit stay (4 vs two; days; p < 0.001) and ventilation support (34 vs 19; hours; p < 0.001), compared with daytime group. The risk factors for operative mortality were night-time surgery (odds ratio [OR], 1.545; p = 0.027), age (odds ratio, 1.152; p < 0.001), total arch replacement (OR, 2.265; p < 0.001) and previous aortic surgery (OR, 2.376; p = 0.003). CONCLUSION Night-time surgical repair may be associated with higher operative mortality of patients with TAAD. Nevertheless, it is reasonable to offer emergency surgery at night-time for such patients who were more likely to present disastrous complications with delayed surgical intervention, as outcomes indicate acceptable operative mortality.

Abstract
BACKGROUND Bleeding is a feared complication of antiplatelets (APTs) and oral anti-coagulants (OACs) use. Asians are at higher risk of bleeding from APT/OAC compared to Western population. Our study aims to investigate the impact of preinjury APT/OAC use on outcomes of moderate to severe blunt trauma. METHODS This is a retrospective cohort study from Jan 2017 - Dec 2019 of all patients with moderate to severe blunt trauma. A 1:2 propensity score matching (PSM) analysis was performed to address for confounding factors. Our primary outcome was in-hospital mortality. Our secondary outcomes were severity of head injury and need for emergency surgery within the first 24 hours. RESULTS There were 592 patients (APT/OAC n=72, no APT/OAC n=520) included in our study. The median age was 74 years in APT/OAC and 58 years in no APT/OAC. PSM resulted in 150 patients (APT/OAC n=50, no APT/OAC n=100). In the PSM cohort, more patients with APT/OAC use had ischemic heart disease (76% vs 0%, P<0.001). APT/OAC use was independently associated with higher in-hospital mortality (22.0% vs 9.0%, Odds ratio (OR) 3.00, 95% Confidence interval (CI): 1.05, 8.56, P=0.040) Severity of head injury (abbreviated injury scale in APT/OAC: 3.33 ± 1.53, vs 2.97 ± 1.43, P=0.380) and need for emergency surgery (APT/OAC 16.2% vs 11.0%, P=0.434) was comparable between APT/OAC and no APT/OAC. CONCLUSIONS Preinjury APT/OAC use was associated with higher in-hospital mortality. Severity of head injury and need for emergency surgery within 24 hours from admission were comparable between APT/OAC use and no APT/OAC use.
