Quality of Life in Patients Undergoing Emergency Surgery for Complex Colorectal Cancer: Protocol and Piloting of the Surgical Utilization and Recovery Patterns for Advanced Stage Colorectal Cancer Study

Introduction: Globally, cancer is the leading cause of mortality, with colorectal neoplasia ranking third in terms of incidence and mortality worldwide. Patients face disease- and treatment-specific impacts, which can significantly influence their quality of life (QoL). Aim: This study aimed to propose a protocol to measure in-hospital and long-term QoL in patients with complicated colorectal cancer (CRC). Material and Methods: multicenter prospective observational cohort study. Results: QoL is a multidimensional concept that includes criteria for physical, mental, emotional, and social functionality as perceived by the patient. Periodically evaluating QoL offers measurable and objective tools to intervene at the appropriate time to decrease the Years of Life Lost and Years Lived with Disabilities for CRC patients. However, a structured and functional system requires dedicated and common institutional effort. A pilot study using this protocol included 69 patients, 65.12+-10.92 years, M:F ratio = 56.5:43.5%. Surgical procedure was right hemicolectomy, left colectomy, transverse colectomy, sigmoidectomy, total colectomy, rectal resection, and colorectal resection with stoma (ileostomy or colostomy) in 21.7%, 11.6%, 2.9%, 11.6%, 1.4%, 23.2%, and 27.5% of the cases, respectively. The mean Global Health Status Score, Symptom Score, and Functional Score was 82.36+-18.60, 11.89+-10.27, and 86.27, 74.50-94.11, respectively. Conclusions: CRC diagnosis has major effects on patients physical and psychological status, and concentrated efforts should be made by the involved medical team and healthcare systems to improve QoL throughout the treatment pathway.

Prehospital trauma care: a clinical review

INTRODUCTION

There are many controversies related to the trauma patient care during the pre-hospital period nowadays. Due to the heterogeneity of the rescue personnel and variability of protocols used in various countries, the benefit of the prehospital advanced life support on morbidity and mortality has been not established.

METHOD

Systematic review of the literature using computer search of the Library of Medicine and the National Institutes of Health International PubMed Medline database using Entre interface.We reviewed the literature in what concerns the basic and advanced life support given to the trauma patients during the prehospital period.

RESULTS

Although the organization of the medical emergency system varies from a country to another, the level of patient'scare can be classified into two main categories: Basic Life Support (BLS) and Advanced Life Support (ALS).There are many studies addressing what to be done at the scene.The prehospital care can be divided into two extremes: stay and play/treat then transfer or scoop and run/load and go.

CONCLUSIONS

A balance between "scoop and run" and "stay and play" is probably the best approach for trauma patients. The chosen approach should be made according to the mechanism of injury (blunt versus penetrating trauma), distance to the trauma center (urban versus rural) and the available resources.

Personalized surveillance in colorectal cancer: Integrating circulating tumor DNA and artificial intelligence into post-treatment follow-up

Given the growing burden of colorectal cancer (CRC) as a global health challenge, it becomes imperative to focus on strategies that can mitigate its impact. Post-treatment surveillance has emerged as essential for early detection of recurrence, significantly improving patient outcomes. However, intensive surveillance strategies have shown mixed results compared to less intensive methods, emphasizing the necessity for personalized, risk-adapted approaches. The observed suboptimal adherence to existing surveillance protocols underscores the urgent need for more tailored and efficient strategies. In this context, circulating tumor DNA (ctDNA) emerges as a promising biomarker with significant potential to revolutionize post-treatment surveillance, demonstrating high specificity [0.95, 95% confidence interval (CI): 0.91-0.97] and robust diagnostic odds (37.6, 95%CI: 20.8-68.0) for recurrence detection. Furthermore, artificial intelligence and machine learning models integrating patient-specific and tumor features can enhance risk stratification and optimize surveillance strategies. The reported area under the receiver operating characteristic curve, measuring artificial intelligence model performance in predicting CRC recurrence, ranged from 0.581 and 0.593 at the lowest to 0.979 and 0.978 at the highest in training and validation cohorts, respectively. Despite this promise, addressing cost, accessibility, and extensive validation remains crucial for equitable integration into clinical practice.

ESCP Enhanced Recovery Collaborating Group. An international assessment of the adoption of enhanced recovery after surgery (ERAS®) principles across colorectal units in 2019-2020

AIM

The Enhanced Recovery After Surgery (ERAS®) Society guidelines aim to standardize perioperative care in colorectal surgery via 25 principles. We aimed to assess the variation in uptake of these principles across an international network of colorectal units.

METHOD

An online survey was circulated amongst European Society of Coloproctology members in 2019-2020. For each ERAS principle, respondents were asked to score how frequently the principle was implemented in their hospital, from 1 ('rarely') to 4 ('always'). Respondents were also asked to recall whether practice had changed since 2017. Subgroup analyses based on hospital characteristics were conducted.

RESULTS

Of hospitals approached, 58% responded to the survey (195/335), with 296 individual responses (multiple responses were received from some hospitals). The majority were European (163/195, 83.6%). Overall, respondents indicated they 'most often' or 'always' adhered to most individual ERAS principles (18/25, 72%). Variability in the uptake of principles was reported, with universal uptake of some principles (e.g., prophylactic antibiotics; early mobilization) and inconsistency from 'rarely' to 'always' in others (e.g., no nasogastric intubation; no preoperative fasting and carbohydrate drinks). In alignment with 2018 ERAS guideline updates, adherence to principles for prehabilitation, managing anaemia and postoperative nutrition appears to have increased since 2017.

CONCLUSIONS

Uptake of ERAS principles varied across hospitals, and not all 25 principles were equally adhered to. Whilst some principles exhibited a high level of acceptance, others had a wide variability in uptake indicative of controversy or barriers to uptake. Further research into specific principles is required to improve ERAS implementation.

Global 30-Day Morbidity and Mortality of Primary Bariatric Surgery Combined with Another Procedure: The BLEND Study

BACKGROUND

No robust data are available on the safety of primary bariatric and metabolic surgery (BMS) alone compared to primary BMS combined with other procedures.

OBJECTIVES

The objective of this study is to collect a 30-day mortality and morbidity of primary BMS combined with cholecystectomy, ventral hernia repair, or hiatal hernia repair.

SETTING

This is as an international, multicenter, prospective, and observational audit of patients undergoing primary BMS combined with one or more additional procedures.

METHODS

The audit took place from January 1 to June 30, 2022. A descriptive analysis was conducted. A propensity score matching analysis compared the BLEND study patients with those from the GENEVA cohort to obtain objective evaluation between combined procedures and primary BMS alone.

RESULTS

A total of 75 centers submitted data on 1036 patients. Sleeve gastrectomy was the most commonly primary BMS (N = 653, 63%), and hiatal hernia repair was the most commonly concomitant procedure (N = 447, 43.1%). RYGB accounted for the highest percentage (20.6%) of a 30-day morbidity, followed by SG (10.5%). More than one combined procedures had the highest morbidities among all combinations (17.1%). Out of overall 134 complications, 129 (96.2%) were Clavien-Dindo I-III, and 4 were CD V. Patients who underwent a primary bariatric surgery combined with another procedure had a pronounced increase in a 30-day complication rate compared with patients who underwent only BMS (12.7% vs. 7.1%).

CONCLUSION

Combining BMS with another procedure increases the risk of complications, but most are minor and require no further treatment. Combined procedures with primary BMS is a viable option to consider in selected patients following multi-disciplinary discussion.

Markers of hyperglycemia in the vitreous humor. A systematic review and meta-analysis

BACKGROUND

Vitreous humor has been extensively used in forensic practice to assess hyperglycemia after death. The results from different articles, for various hyperglycemia markers are highly variable, and a systematic analysis of the results from studies currently used in forensic practice as landmarks has not yet been performed. Therefore, we aimed to evaluate to usefulness and limits of using the values of vitreous glucose, lactic acid, beta-hydroxybutyrate, and 1,5 Anhydro-d-glucitol to detect postmortem hyperglycemia.

MATERIALS AND METHODS

For this purpose, we performed a systematic review and a meta-analysis using the random-effects model to identify the threshold values and average differences for the markers mentioned above in the vitreous humor of diabetic versus nondiabetic subjects.

RESULTS

We included eleven studies in the meta-analysis and found the following mean differences between the diabetic and nondiabetic groups: for glucose - 91.4 mg/dl, for lactate - 34.17 mg/dl, for the Traub formula - 111 mg/dl, for fructosamine - 0.71 mmol/L, for beta-hydroxybutyrate - 36.55 mg/dl and 1,5 Anhydro-d-glucitol - -15.2 mg/dl. We also gave practical recommendations, based on the range of values and 95% confidence intervals in normal subjects and controls to identify antemortem hyperglycemia and evaluated, whenever possible, threshold values for fatal diabetes.

CONCLUSIONS

Glucose, Traub formula, fructosamine, and beta-hydroxy-butyrate can be used to detect postmortem hyperglycemia with some limitations; 1,5 Anhydro-d-glucitol can only be used to suggest the absence of a hyperglycemic status before death.

Stoma-free survival after anastomotic leak following rectal cancer resection: worldwide cohort of 2470 patients

BACKGROUND

The optimal treatment of anastomotic leak after rectal cancer resection is unclear. This worldwide cohort study aimed to provide an overview of four treatment strategies applied.

METHODS

Patients from 216 centres and 45 countries with anastomotic leak after rectal cancer resection between 2014 and 2018 were included. Treatment was categorized as salvage surgery, faecal diversion with passive or active (vacuum) drainage, and no primary/secondary faecal diversion. The primary outcome was 1-year stoma-free survival. In addition, passive and active drainage were compared using propensity score matching (2 : 1).

RESULTS

Of 2470 evaluable patients, 388 (16.0 per cent) underwent salvage surgery, 1524 (62.0 per cent) passive drainage, 278 (11.0 per cent) active drainage, and 280 (11.0 per cent) had no faecal diversion. One-year stoma-free survival rates were 13.7, 48.3, 48.2, and 65.4 per cent respectively. Propensity score matching resulted in 556 patients with passive and 278 with active drainage. There was no statistically significant difference between these groups in 1-year stoma-free survival (OR 0.95, 95 per cent c.i. 0.66 to 1.33), with a risk difference of -1.1 (95 per cent c.i. -9.0 to 7.0) per cent. After active drainage, more patients required secondary salvage surgery (OR 2.32, 1.49 to 3.59), prolonged hospital admission (an additional 6 (95 per cent c.i. 2 to 10) days), and ICU admission (OR 1.41, 1.02 to 1.94). Mean duration of leak healing did not differ significantly (an additional 12 (-28 to 52) days).

CONCLUSION

Primary salvage surgery or omission of faecal diversion likely correspond to the most severe and least severe leaks respectively. In patients with diverted leaks, stoma-free survival did not differ statistically between passive and active drainage, although the increased risk of secondary salvage surgery and ICU admission suggests residual confounding.

COVID-19 infection is a significant risk factor for death in patients presenting with acute cholecystitis: a secondary analysis of the ChoCO-W cohort study

BACKGROUND

During the coronavirus disease (COVID-19) pandemic, there has been a surge in cases of acute cholecystitis. The ChoCO-W global prospective study reported a higher incidence of gangrenous cholecystitis and adverse outcomes in COVID-19 patients. Through this secondary analysis of the ChoCO-W study data, we aim to identify significant risk factors for mortality in patients with acute cholecystitis during the COVID-19 pandemic, emphasizing the role of COVID-19 infection in patient outcomes and treatment efficacy."

METHODS

The ChoCO-W global prospective study reported data from 2546 patients collected at 218 centers from 42 countries admitted with acute cholecystitis during the COVID-19 pandemic, from October 1, 2020, to October 31, 2021. Sixty-four of them died. Nonparametric statistical univariate analysis was performed to compare patients who died and patients who survived. Significant factors were then entered into a logistic regression model to define factors predicting mortality.

RESULTS

The significant independent factors that predicted death in the logistic regression model with were COVID-19 infection (p < 0.001), postoperative complications (p < 0.001), and type (open/laparoscopic) of surgical intervention (p = 0.003). The odds of death increased 5 times with the COVID-19 infection, 6 times in the presence of complications, and it was reduced by 86% with adequate source control. Survivors predominantly underwent urgent laparoscopic cholecystectomy (52.3% vs. 23.4%).

CONCLUSIONS

COVID-19 was an independent risk factor for death in patients with acute cholecystitis. Early laparoscopic cholecystectomy has emerged as the cornerstone of treatment for hemodynamically stable patients.

Massive intraoperative bleeding after laparoscopic assisted abdominoperineal resection: a case report and systematic review of the literature

INTRODUCTION

The laparoscopic-assisted abdominoperineal resection (LAPR) has been proved to be associated with a shorter postoperative recovery, with equivalent oncological results and similar survival when compared with conventional open surgery, for patients with low rectal cancer.

METHOD

Case report of a massive intraoperative bleeding during LAPR and systematic review of the English language literature, using PubMed Medline, ISI Thopmson, OVID and EMBASE databases.

RESULTS

58 years old patient admitted in emergency setting or rectal bleeding. Rectal examination revealed a protruding,frail tumor, located 2 cm from the anal verge. Total colono scopy revealed an infiltrative, protruding tumor, situated at 2 cm from the anal verge, with a 5 cm cranial extension,without any additional colonic lesions. Computed Tomography showed a 4,5 cm circumferential rectal wall thickening, without any enlarged mesorectal or abdominal lymph nodes. The patient was transported to operating room for a LAPR. During final hemostasis, at the level of perineal surgical wound, an acute massive bleeding occurred from the presacral vessels with severe blood loss. This bleeding couldnot be managed laparo scopicaly and conversion to laparotomywas decided, with pelvic packing. At 48 hours after the initial surgical approach, the tamponing packs were removed, without signs of active bleeding. There were applied haemostatic agents and the perineal wound was sutured, without further rbleeding during in-hospital stay.

CONCLUSIONS

A rapid and effective control of the presacral bleeding is mandatory to prevent a fatal outcome. Pelvic packing remains a life-saving procedure and the treatment of choice in severe cases.

[Selective nonoperative management of solid abdominal visceral lesions]

Selective nonoperative management of abdominal visceral lesions is one of the most important and challenging changes that occurred in the traumatized patient care over the last 20 years. The main advantage of this type of management is the avoidance of unnecessary/nontherapeutic laparotomies. The trauma surgeons who deal with this type of treatment are worried of missed abdominal injuries. Modern diagnostic tools (spiral CT, ultrasound, angiography, laparoscopy) allow the trauma surgeon to accurately characterize the lesions to be nonoperative addressed. This literature review discusses the main elements of selective nonoperative management of principle solid visceral lesions (liver, spleen, kidney). We highlight the advantages and limitations of the main diagnostic instruments used for evaluation of trauma patiens allocated to nonoperative management.

Current strategies in the therapeutic approach for adenocarcinoma of the ampulla of Vater

INTRODUCTION

Ampulla of Vater tumors, neoplastic diseases located at the confluence of the common bile duct with the main pancreatic duct; represent 0.2% of all gastrointestinal cancers.

METHOD

Retrospective study of all patients admitted in the Emergency Hospital of Bucharest Romania between January 2008 and January 2013, the only selection criterion used being a pathology report which describes an ampulla of Vater carcinoma. We have also performed a review of the medical literature up to 2013, using the PubMed/Medline, Proquest Hospital Collection, Science Direct, Cochrane Library and Web of Science databases. We have used different combinations of the following keywords: "ampulla of Vater", "carcinoma", "resection", reviewing the reference list of retrieved articles for further relevant studies.

RESULTS

Forty eight patients with ampulla of Vater carcinoma were identified, of whom 59.6% men, 71% from urban areas, and a mean age of 66 ± 13.3 years. Most patients were admitted for obstructive jaundice (49%), right upper quadrant abdominal pain (19%), nausea and loss of appetite in 13%, loss of weight (13%) and upper digestive obstruction in 6% of cases. All patients were evaluated with abdominal transparietal ultrasonography and double contrast, pancreatic protocol, Mutidetector Row Computed Tomography. The abdominal Magnetic Resonance Imaging was performed in 10 cases, upper gastrointestinal endoscopy in 9 cases, and Endoscopic Retrograde Cholangiopancreatography in 39 cases. According to the AJCC Cancer Staging 9% were into stage I, 47% into stage II, 40% into stage III and 4% into stage IV of the disease. The therapeutic approach was surgical for 44 patients and an endoscopic palliation with stent insertion in 4 cases. The surgical procedure was represented by Whipple pancreatoduodenectomy in 27 cases, pylorus preserving pancreatoduodenectomy in 15 cases and exploratory laparotomy in 2 cases. Early morbidity was represented by pancreatic leakage in 4 cases.

CONCLUSIONS

There are clinical scenarios in which it is quite challenging to distinguish a primary ampullary adenocarcinoma based on a preoperative workup. Nevertheless, an aggressive approach should be performed, knowing the higher resectability rates and a five-year survival for these patients. Complete surgical resection should be performed in all medically fit patients, candidates for pancreatoduodenectomy, by a high volume, trained surgeon, able to offer a low morbidity and mortality.

Global, regional, and national prevalence of child and adolescent overweight and obesity, 1990-2021, with forecasts to 2050: a forecasting study for the Global Burden of Disease Study 2021

BACKGROUND

Despite the well documented consequences of obesity during childhood and adolescence and future risks of excess body mass on non-communicable diseases in adulthood, coordinated global action on excess body mass in early life is still insufficient. Inconsistent measurement and reporting are a barrier to specific targets, resource allocation, and interventions. In this Article we report current estimates of overweight and obesity across childhood and adolescence, progress over time, and forecasts to inform specific actions.

METHODS

Using established methodology from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021, we modelled overweight and obesity across childhood and adolescence from 1990 to 2021, and then forecasted to 2050. Primary data for our models included 1321 unique measured and self-reported anthropometric data sources from 180 countries and territories from survey microdata, reports, and published literature. These data were used to estimate age-standardised global, regional, and national overweight prevalence and obesity prevalence (separately) for children and young adolescents (aged 5-14 years, typically in school and cared for by child health services) and older adolescents (aged 15-24 years, increasingly out of school and cared for by adult services) by sex for 204 countries and territories from 1990 to 2021. Prevalence estimates from 1990 to 2021 were generated using spatiotemporal Gaussian process regression models, which leveraged temporal and spatial correlation in epidemiological trends to ensure comparability of results across time and geography. Prevalence forecasts from 2022 to 2050 were generated using a generalised ensemble modelling approach assuming continuation of current trends. For every age-sex-location population across time (1990-2050), we estimated obesity (vs overweight) predominance using the log ratio of obesity percentage to overweight percentage.

FINDINGS

Between 1990 and 2021, the combined prevalence of overweight and obesity in children and adolescents doubled, and that of obesity alone tripled. By 2021, 93·1 million (95% uncertainty interval 89·6-96·6) individuals aged 5-14 years and 80·6 million (78·2-83·3) aged 15-24 years had obesity. At the super-region level in 2021, the prevalence of overweight and of obesity was highest in north Africa and the Middle East (eg, United Arab Emirates and Kuwait), and the greatest increase from 1990 to 2021 was seen in southeast Asia, east Asia, and Oceania (eg, Taiwan [province of China], Maldives, and China). By 2021, for females in both age groups, many countries in Australasia (eg, Australia) and in high-income North America (eg, Canada) had already transitioned to obesity predominance, as had males and females in a number of countries in north Africa and the Middle East (eg, United Arab Emirates and Qatar) and Oceania (eg, Cook Islands and American Samoa). From 2022 to 2050, global increases in overweight (not obesity) prevalence are forecasted to stabilise, yet the increase in the absolute proportion of the global population with obesity is forecasted to be greater than between 1990 and 2021, with substantial increases forecast between 2022 and 2030, which continue between 2031 and 2050. By 2050, super-region obesity prevalence is forecasted to remain highest in north Africa and the Middle East (eg, United Arab Emirates and Kuwait), and forecasted increases in obesity are still expected to be largest across southeast Asia, east Asia, and Oceania (eg, Timor-Leste and North Korea), but also in south Asia (eg, Nepal and Bangladesh). Compared with those aged 15-24 years, in most super-regions (except Latin America and the Caribbean and the high-income super-region) a greater proportion of those aged 5-14 years are forecasted to have obesity than overweight by 2050. Globally, 15·6% (12·7-17·2) of those aged 5-14 years are forecasted to have obesity by 2050 (186 million [141-221]), compared with 14·2% (11·4-15·7) of those aged 15-24 years (175 million [136-203]). We forecasted that by 2050, there will be more young males (aged 5-14 years) living with obesity (16·5% [13·3-18·3]) than overweight (12·9% [12·2-13·6]); while for females (aged 5-24 years) and older males (aged 15-24 years), overweight will remain more prevalent than obesity. At a regional level, the following populations are forecast to have transitioned to obesity (vs overweight) predominance before 2041-50: children and adolescents (males and females aged 5-24 years) in north Africa and the Middle East and Tropical Latin America; males aged 5-14 years in east Asia, central and southern sub-Saharan Africa, and central Latin America; females aged 5-14 years in Australasia; females aged 15-24 years in Australasia, high-income North America, and southern sub-Saharan Africa; and males aged 15-24 years in high-income North America.

INTERPRETATION

Both overweight and obesity increased substantially in every world region between 1990 and 2021, suggesting that current approaches to curbing increases in overweight and obesity have failed a generation of children and adolescents. Beyond 2021, overweight during childhood and adolescence is forecast to stabilise due to further increases in the population who have obesity. Increases in obesity are expected to continue for all populations in all world regions. Because substantial change is forecasted to occur between 2022 and 2030, immediate actions are needed to address this public health crisis.

Discharge protocol in acute pancreatitis: an international survey and cohort analysis

There are several overlapping clinical practice guidelines in acute pancreatitis (AP), however, none of them contains suggestions on patient discharge. The Hungarian Pancreatic Study Group (HPSG) has recently developed a laboratory data and symptom-based discharge protocol which needs to be validated. (1) A survey was conducted involving all members of the International Association of Pancreatology (IAP) to understand the characteristics of international discharge protocols. (2) We investigated the safety and effectiveness of the HPSG-discharge protocol. According to our international survey, 87.5% (49/56) of the centres had no discharge protocol. Patients discharged based on protocols have a significantly shorter median length of hospitalization (LOH) (7 (5;10) days vs. 8 (5;12) days) p < 0.001), and a lower rate of readmission due to recurrent AP episodes (p = 0.005). There was no difference in median discharge CRP level among the international cohorts (p = 0.586). HPSG-protocol resulted in the shortest LOH (6 (5;9) days) and highest median CRP (35.40 (13.78; 68.40) mg/l). Safety was confirmed by the low rate of readmittance (n = 35; 5%). Discharge protocol is necessary in AP. The discharge protocol used in this study is the first clinically proven protocol. Developing and testifying further protocols are needed to better standardize patients' care.

Traumatic Tricuspid Valve Rupture after Blunt Chest Trauma - A Case Report and Review of the Literature

INTRODUCTION

Despite the high frequency of thoracic injuries secondary to traffic related accidents, the blunt cardiac valve rupture is extremely rare.

METHOD

Case report and review of the literature using PubMed/MEDLINE and EMBASE databases.

RESULT

A 38 year old female patient, victim of car accident was admitted. On primary survey the patient was conscious, cooperative and hemodynamic and respiratory stable. On secondary survey was found a bilateral open leg fracture and a seat belt sign. Whole body Computed Tomography revealed minimal haemorrhagic contusion of the cortex, left hemopneumothorax and right pneumothorax, bilateral rib fractures, liver contusion, left femoral neck fracture and fracture to the lumbar spinal column. After bilateral pleurostomy, the patient becomes hemodynamically unstable, but with no signs of external bleeding. The transthoracic echocardiography revealed an acute severe tricuspid regurgitation with hepatic veins reflux. After orthopaedic surgeries, the tricuspid valve rupture was managed by replacing the valve with a bioprostheses. The hospital stay was 122 days.

CONCLUSION

Only a high index of suspicion may reveal blunt cardiac lesions as a cause for hemodynamic instability in acute setting.

Novel Textbook Outcomes following emergency laparotomy: Delphi exercise

BACKGROUND

Textbook outcomes are composite outcome measures that reflect the ideal overall experience for patients. There are many of these in the elective surgery literature but no textbook outcomes have been proposed for patients following emergency laparotomy. The aim was to achieve international consensus amongst experts and patients for the best Textbook Outcomes for non-trauma and trauma emergency laparotomy.

METHODS

A modified Delphi exercise was undertaken with three planned rounds to achieve consensus regarding the best Textbook Outcomes based on the category, number and importance (Likert scale of 1-5) of individual outcome measures. There were separate questions for non-trauma and trauma. A patient engagement exercise was undertaken after round 2 to inform the final round.

RESULTS

A total of 337 participants from 53 countries participated in all three rounds of the exercise. The final Textbook Outcomes were divided into 'early' and 'longer-term'. For non-trauma patients the proposed early Textbook Outcome was 'Discharged from hospital without serious postoperative complications (Clavien-Dindo ≥ grade III; including intra-abdominal sepsis, organ failure, unplanned re-operation or death). For trauma patients it was 'Discharged from hospital without unexpected transfusion after haemostasis, and no serious postoperative complications (adapted Clavien-Dindo for trauma ≥ grade III; including intra-abdominal sepsis, organ failure, unplanned re-operation on or death)'. The longer-term Textbook Outcome for both non-trauma and trauma was 'Achieved the early Textbook Outcome, and restoration of baseline quality of life at 1 year'.

CONCLUSION

Early and longer-term Textbook Outcomes have been agreed by an international consensus of experts for non-trauma and trauma emergency laparotomy. These now require clinical validation with patient data.

Global Incidence and Risk Factors Associated With Postoperative Urinary Retention Following Elective Inguinal Hernia Repair: The Retention of Urine After Inguinal Hernia Elective Repair (RETAINER I) Study

IMPORTANCE

Postoperative urinary retention (POUR) is a well-recognized complication of inguinal hernia repair (IHR). A variable incidence of POUR has previously been reported in this context, and contradictory evidence surrounds potential risk factors.

OBJECTIVE

To ascertain the incidence of, explore risk factors for, and determine the health service outcomes of POUR following elective IHR.

DESIGN, SETTING, AND PARTICIPANTS

The Retention of Urine After Inguinal Hernia Elective Repair (RETAINER I) study, an international, prospective cohort study, recruited participants between March 1 and October 31, 2021. This study was conducted across 209 centers in 32 countries in a consecutive sample of adult patients undergoing elective IHR.

EXPOSURE

Open or minimally invasive IHR by any surgical technique, under local, neuraxial regional, or general anesthesia.

MAIN OUTCOMES AND MEASURES

The primary outcome was the incidence of POUR following elective IHR. Secondary outcomes were perioperative risk factors, management, clinical consequences, and health service outcomes of POUR. A preoperative International Prostate Symptom Score was measured in male patients.

RESULTS

In total, 4151 patients (3882 male and 269 female; median [IQR] age, 56 [43-68] years) were studied. Inguinal hernia repair was commenced via an open surgical approach in 82.2% of patients (n = 3414) and minimally invasive surgery in 17.8% (n = 737). The primary form of anesthesia was general in 40.9% of patients (n = 1696), neuraxial regional in 45.8% (n = 1902), and local in 10.7% (n = 446). Postoperative urinary retention occurred in 5.8% of male patients (n = 224), 2.97% of female patients (n = 8), and 9.5% (119 of 1252) of male patients aged 65 years or older. Risk factors for POUR after adjusted analyses included increasing age, anticholinergic medication, history of urinary retention, constipation, out-of-hours surgery, involvement of urinary bladder within the hernia, temporary intraoperative urethral catheterization, and increasing operative duration. Postoperative urinary retention was the primary reason for 27.8% of unplanned day-case surgery admissions (n = 74) and 51.8% of 30-day readmissions (n = 72).

CONCLUSIONS

The findings of this cohort study suggest that 1 in 17 male patients, 1 in 11 male patients aged 65 years or older, and 1 in 34 female patients may develop POUR following IHR. These findings could inform preoperative patient counseling. In addition, awareness of modifiable risk factors may help to identify patients at increased risk of POUR who may benefit from perioperative risk mitigation strategies.

Predictors of anastomotic leak and conduit necrosis after oesophagectomy: Results from the oesophago-gastric anastomosis audit (OGAA)

BACKGROUND

Both anastomotic leak (AL) and conduit necrosis (CN) after oesophagectomy are associated with high morbidity and mortality. Therefore, the identification of preoperative, modifiable risk factors is desirable. The aim of this study was to generate a risk scoring model for AL and CN after oesophagectomy.

METHODS

Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018-December 2018. Definitions for AL and CN were those set out by the Oesophageal Complications Consensus Group. Univariate and multivariate analyses were performed to identify risk factors for both AL and CN. A risk score was then produced for both AL and CN using the derivation set, then internally validated using the validation set.

RESULTS

This study included 2247 oesophagectomies across 137 hospitals in 41 countries. The AL rate was 14.2% and CN rate was 2.7%. Preoperative factors that were independent predictors of AL were cardiovascular comorbidity and chronic obstructive pulmonary disease. The risk scoring model showed insufficient predictive ability in internal validation (area under the receiver-operating-characteristic curve [AUROC] = 0.618). Preoperative factors that were independent predictors of CN were: body mass index, Eastern Cooperative Oncology Group performance status, previous myocardial infarction and smoking history. These were converted into a risk-scoring model and internally validated using the validation set with an AUROC of 0.775.

CONCLUSION

Despite a large dataset, AL proves difficult to predict using preoperative factors. The risk-scoring model for CN provides an internally validated tool to estimate a patient's risk preoperatively.

Probability of Survival Scores in Different Trauma Registries: A Systematic Review

INTRODUCTION

A mixed score to predict the probability of survival has a key role in the modern trauma systems. The aim of the current studies is to summarize the current knowledge about estimation of survival in major trauma patients, in different trauma registries.

METHOD

Systematic review of the literature using electronic search in the PubMed/Medline, Web of Science Core Collection and EBSCO databases. We have used as a MeSH or truncated words a combination of trauma "probability of survival" and "mixed scores". The search strategy in PubMed was: "((((trauma(MeSH Major Topic)) OR injury(Title/Abstract)) AND score (Title/Abstract)) AND survival) AND registry (Title/Abstract))))". We used as a language selection only English language literature.

RESULTS

There is no consensus between the major trauma registries, regarding probability of survival estimation in major trauma patients. The German (RISC II), United Kingdom (PS Model 14) trauma registries scores are based of the largest population, with demographics updated to the nowadays European injury pattern. The revised TRISS, resulting from the USA National Trauma Database, seems to be inaccurate for trauma systems managing predominantly blunt injuries.

CONCLUSIONS

The probability of survival should be evaluated in all major trauma patients, with a score derived from a population which reproduce the current demographics.Only a careful audit of the unpredicted deaths may continuously improve our care for severely injured patients.

The Operating Room management for emergency Surgical Activity (ORSA) study: a WSES international survey

BACKGROUND

Despite advances and improvements in the management of surgical patients, emergency and trauma surgery is associated with high morbidity and mortality. This may be due in part to delays in definitive surgical management in the operating room (OR). There is a lack of studies focused on OR prioritization and resource allocation in emergency surgery. The Operating Room management for emergency Surgical Activity (ORSA) study was conceived to assess the management of operating theatres and resources from a global perspective among expert international acute care surgeons.

METHOD

The ORSA study was conceived as an international web survey. The questionnaire was composed of 23 multiple-choice and open questions. Data were collected over 3 months. Participation in the survey was voluntary and anonymous.

RESULTS

One hundred forty-seven emergency and acute care surgeons answered the questionnaire; the response rate was 58.8%. The majority of the participants come from Europe. One hundred nineteen surgeons (81%; 119/147) declared to have at least one emergency OR in their hospital; for the other 20/147 surgeons (13.6%), there is not a dedicated emergency operating room. Forty-six (68/147)% of the surgeons use the elective OR to perform emergency procedures during the day. The planning of an emergency surgical procedure is done by phone by 70% (104/147) of the surgeons.

CONCLUSIONS

There is no dedicated emergency OR in the majority of hospitals internationally. Elective surgical procedures are usually postponed or even cancelled to perform emergency surgery. It is a priority to validate an effective universal triaging and scheduling system to allocate emergency surgical procedures. The new Timing in Acute Care Surgery (TACS) was recently proposed and validated by a Delphi consensus as a clear and reproducible triage tool to timely perform an emergency surgical procedure according to the clinical severity of the surgical disease. The new TACS needs to be prospectively validated in clinical practice. Logistics have to be assessed using a multi-disciplinary approach to improve patients' safety, optimise the use of resources, and decrease costs.
