BACKGROUND: There is increasing interest in the regionalization of surgical procedures. However, evidence on the volume-outcome relationship for emergency intra-abdominal surgery is not well-synthesized. This systematic review and meta-analysis summarize evidence regarding the impact of hospital and surgeon volume on complications. METHODS: We identified cohort studies assessing the impact of hospital/surgeon volume on postoperative complications after emergency intra-abdominal procedures, with data collected after the year 2000 through a literature search without language restriction in the PubMed, Web of Science, and Cochrane databases. A weighted overall complication rate was calculated, and a random effect regression model was used for a summary odds ratio. A sensitivity analysis with the removal of studies contributing to heterogeneity was performed (PROSPERO: CRD42022358879). RESULTS: The search yielded 2,153 articles, of which 9 cohort studies were included and determined to be good quality according to the Newcastle Ottawa Scale. These studies reported outcomes for the following procedures: cholecystectomy, colectomy, appendectomy, small bowel resection, peptic ulcer repair, adhesiolysis, laparotomy, and hernia repair. Eight studies (2,358,093 patients) with available data were included in the meta-analysis. Low hospital volume was not significantly associated with higher complications. In the sensitivity analysis, low hospital volume was significantly associated with higher complications when appropriate heterogeneity was achieved. Low surgeon volume was associated with higher complications, and these findings remained consistent in the sensitivity analysis. CONCLUSION: We found that hospital and surgeon volume was significantly associated with higher complications in patients undergoing emergency intra-abdominal surgery when appropriate heterogeneity was achieved.

BACKGROUND: Surgical site infections (SSI) are a common complication of laparotomy incisions. The role of Negative Pressure Wound Therapy (NPWT) in preventing SSIs has not yet been explored in a nationwide analysis. We aimed to evaluate the association of the prophylactic use of NPWT with SSIs in patients undergoing an emergency laparotomy procedure. METHODS: We conducted a retrospective cohort study using the National Surgery Quality Initiative Program (NSQIP) database from 2013 to 2020. We included patients ≥18 years undergoing an emergency laparotomy. We performed a 1:1 propensity matching adjusting for patient age, sex, race, ethnicity, BMI, comorbid conditions, ASA status, diagnosis, preoperative factors and laboratory variables, procedure type, wound class, and intraoperative variables. We compared NPWT with standard dressings in two patient populations: 1. patients with completely closed (skin and fascia) laparotomy incisions and 2. patients with partially closed (fascia only) laparotomy incisions. Our primary outcome was the rate of incisional SSI. Secondary outcomes included the type of SSI, postoperative 30-day complications, postoperative hospital length of stay, and discharge disposition. RESULTS: We included 65,803 patients with completely closed incisions of whom 387 patients received NPWT. There was no significant difference in the rate of total SSIs (13.4 â% vs. 11.9 â%; p â= â0.52) in the matched population of 387 pairs. We included 7285 patients with partially closed incisions of whom 477 patients received NPWT. There was no significant difference in the rate of total SSIs (3.6 â% vs. 4.4 â%; p â= â0.51) in the matched population of 477 pairs. Secondary outcomes did not differ significantly in either group. CONCLUSION: The rate of SSIs was not significantly different when prophylactic NPWT was used compared to standard dressings for patients with a closed or partially closed laparotomy incision.

BACKGROUND: The impact of COVID-19 infection at the time of traumatic injury remains understudied. Previous studies demonstrate that the rate of COVID-19 vaccination among trauma patients remains lower than in the general population. This study aims to understand the impact of concomitant COVID-19 infection on outcomes in trauma patients. METHODS: We conducted a retrospective cohort study of patients ≥18 years old admitted to a level I trauma center from March 2020 to December 2022. Patients tested for COVID-19 infection using a rapid antigen/PCR test were included. We matched patients using 2:1 propensity accounting for age, gender, race, comorbidities, vaccination status, injury severity score (ISS), type and mechanism of injury, and GCS at arrival. The primary outcome was inpatient mortality. Secondary outcomes included hospital length of stay (LOS), Intensive Care Unit (ICU) LOS, 30-day readmission, and major complications. RESULTS: Of the 4448 patients included, 168 (3.8%) were positive (COV+). Compared with COVID-19-negative (COV-) patients, COV+ patients were similar in age, sex, BMI, ISS, type of injury, and regional AIS. The proportion of White and non-Hispanic patients was higher in COV- patients. Following matching, 154 COV+ and 308 COV- patients were identified. COVID-19-positive patients had a higher rate of mortality (7.8% vs 2.6%; P = .010), major complications (15.6% vs 8.4%; P = .020), and thrombotic complications (3.9% vs .6%; P = .012). Patients also had a longer hospital LOS (median, 9 vs 5 days; P < .001) and ICU LOS (median, 5 vs 3 days; P = .025). CONCLUSIONS: Trauma patients with concomitant COVID-19 infection have higher mortality and morbidity in the matched population. Focused interventions aimed at recognizing this high-risk group and preventing COVID-19 infection within it should be undertaken.

BACKGROUND: Emergent surgical conditions are common in geriatric patients, often necessitating major operative procedures on frail patients. Understanding risk profiles is crucial for decision-making and establishing goals of care. METHODS: We queried NSQIP 2015-2019 for patients ≥65 years undergoing open abdominal surgery for emergency general surgery conditions. Logistic regression was used to identify 30-day mortality predictors. RESULTS: Of 41,029 patients, 5589 (13.6 â%) died within 30 days of admission. The highest predictors of mortality were ASA status 5 (aOR 9.7, 95 â% CI,3.5-26.8, p â< â0.001), septic shock (aOR 4.9, 95 â% CI,4.5-5.4, p â< â0.001), and dialysis (aOR 2.1, 95 â% CI,1.8-2.4, p â< â0.001). Without risk factors, mortality rates were 11.9 â% after colectomy and 10.2 â% after small bowel resection. Patients with all three risk factors had a mortality rate of 79.4 â% and 100 â% following colectomy and small bowel resection, respectively. CONCLUSIONS: In older adults undergoing emergent open abdominal surgery, septic shock, ASA status, and dialysis were strongly associated with futility of surgical intervention. These findings can inform goals of care and informed decision-making.
RESUMEN
BACKGROUND: COVID-19 vaccination rates in the hospitalized trauma population are not fully characterized and may lag behind the general population. This study aimed to outline COVID-19 vaccination trends in hospitalized trauma patients and examine how hospitalization influences COVID-19 vaccination rates. METHODS: We conducted a retrospective institutional study using our trauma registry paired with the COVID-19 vaccination ENCLAVE registry. We included patients ≥18 years admitted between April 21, 2021 and November 30, 2022. Our primary outcome was the change in vaccination posthospitalization, and secondary analyzed outcomes included temporal trends of vaccination in trauma patients and predictors of non-vaccination. We compared pre and posthospitalization weekly vaccination rates. We performed joinpoint regression to depict temporal trends and multivariate regression for predictors of nonvaccination. RESULTS: The rate of administration of the first vaccine dose increased in the week after hospitalization (P = .018); however, this increase was not sustained in the following weeks. The percentage of unvaccinated patients declined faster in the general population in Massachusetts compared to the hospitalized trauma population. By the conclusion of the study, 27.1% of the trauma population was unvaccinated, whereas <5% of the Massachusetts population was unvaccinated. Urban residence, having multiple hospitalizations, and experiencing moderate to severe frailty were associated with vaccination. Conversely, being in the age groups 18 to 45 years and 46 to 64 years, as well as having Medicaid or self-pay insurance, were linked to being unvaccinated. CONCLUSION: Hospitalization initially increased the rate of administration of the first vaccine dose in trauma patients, but the effect was not sustained. By the conclusion of the study period, a greater percentage of trauma patients were unvaccinated compared to the general population of Massachusetts. Strategies for sustained health care integration need to be developed to address this ongoing challenge in the high-risk trauma population.

Background: More than 20% of the population in the United States suffers from a disability, yet the impact of disability on post-operative outcomes remains understudied. This analysis aims to characterize post-operative infectious complications in patients with disability. Patients and Methods: This was a retrospective review of the National Readmission Database (2019) among patients undergoing common general surgery procedures. As per the U.S. Centers for Disease Control and Prevention (CDC), disability was defined as severe hearing, visual, intellectual, or motor impairment/caregiver dependency. A propensity-matched analysis comparing patients with and without a disability was performed to compare outcomes, including post-operative septic shock, sepsis, bacteremia, pneumonia, catheter-associated urinary tract infection (CAUTI), urinary tract infection (UTI), catheter-associated blood stream infection, Clostridioides Difficile infection, and superficial, deep, and organ/space surgical site infections during index hospitalization. Patients were matched using age, gender, comorbidities, illness severity, income, neighborhood, insurance, elective procedure, and the hospital's bed size and type. Results: A total of 710,548 patients were analysed, of whom 9,451(1.3%) had at least one disability. Motor disability was the most common (3,762; 40.5%), followed by visual, intellectual, and hearing impairment. Patients with disability were older (64 vs. 57 years; p < 0.001), more often insured under Medicare (65.2% vs. 37.3% p < 0.001) and had more medical comorbidities (Elixhauser comorbidity score ≥3; 69.2% vs. 41.9%; p < 0.001). After matching, 9,292 pairs were formed. Patients with a disability had a higher incidence of pneumonia (10.1% vs. 6.5%; p < 0.001), aspiration pneumonia (5.2% vs. 1.4%; p < 0.001), CAUTI (1.0% vs. 0.4%; p < 0.001), UTI (10.4% vs. 6.2%; p < 0.001), and overall infectious complications (21.8% vs. 14.5%; p < 0.001). Conclusions: Severe intellectual, hearing, visual, or motor impairments were associated with a higher incidence of infectious complications. Further investigation is needed to develop interventions to reduce disparities among this high-risk population.

Importance: There is variability in practice and imaging usage to diagnose cervical spine injury (CSI) following blunt trauma in pediatric patients. Objective: To develop a prediction model to guide imaging usage and to identify trends in imaging and to evaluate the PEDSPINE model. Design, Setting, and Participants: This cohort study included pediatric patients (<3 years years) following blunt trauma between January 2007 and July 2017. Of 22 centers in PEDSPINE, 15 centers, comprising level 1 and 2 stand-alone pediatric hospitals, level 1 and 2 pediatric hospitals within an adult hospital, and level 1 adult hospitals, were included. Patients who died prior to obtaining cervical spine imaging were excluded. Descriptive analysis was performed to describe the population, use of imaging, and injury patterns. PEDSPINE model validation was performed. A new algorithm was derived using clinical criteria and formulation of a multiclass classification problem. Analysis took place from January to October 2022. Exposure: Blunt trauma. Main Outcomes and Measures: Primary outcome was CSI. The primary and secondary objectives were predetermined. Results: The current study, PEDSPINE II, included 9389 patients, of which 128 (1.36%) had CSI, twice the rate in PEDSPINE (0.66%). The mean (SD) age was 1.3 (0.9) years; and 70 patients (54.7%) were male. Overall, 7113 children (80%) underwent cervical spine imaging, compared with 7882 (63%) in PEDSPINE. Several candidate models were fitted for the multiclass classification problem. After comparative analysis, the multinomial regression model was chosen with one-vs-rest area under the curve (AUC) of 0.903 (95% CI, 0.836-0.943) and was able to discriminate between bony and ligamentous injury. PEDSPINE and PEDSPINE II models' ability to identify CSI were compared. In predicting the presence of any injury, PEDSPINE II obtained a one-vs-rest AUC of 0.885 (95% CI, 0.804-0.934), outperforming the PEDSPINE score (AUC, 0.845; 95% CI, 0.769-0.915). Conclusion and Relevance: This study found wide clinical variability in the evaluation of pediatric trauma patients with increased use of cervical spine imaging. This has implications of increased cost, increased radiation exposure, and a potential for overdiagnosis. This prediction tool could help to decrease the use of imaging, aid in clinical decision-making, and decrease hospital resource use and cost.

OBJECTIVES: A minimally invasive step-up (MIS) approach for management of necrotizing pancreatitis (NP) has been associated with reduced morbidity and mortality compared with open surgical techniques. We sought to evaluate bleeding complications in NP patients treated with a MIS approach and to describe the management and outcomes of these events. METHODS: An observational, cohort study was performed using a prospectively maintained NP database at a tertiary referral center from 2013 to 2019. RESULTS: Of 119 NP patients, 13% suffering bleeding events, and 18% underwent an intervention. There was a 6-fold higher mortality rate in patients with bleeding events (n = 3; 18.8%) compared with those without (n = 3; 2.9%) ( P = 0.031). The most common intervention for hemorrhage control was endovascular coil embolization (75%), which was successful 88% of the time. Seven patients underwent prophylactic vascular intervention, which was 100% successful in preventing bleeding events from the embolized vessel. CONCLUSIONS: Bleeding events in NP patients treated with a MIS approach are associated with a 6-fold increase in mortality. Endovascular intervention is an effective strategy for the management of bleeding events. Prophylactic embolization may be an effective technique for reducing bleeding complications.

Trauma is one of the most common causes of death, particularly in younger individuals. The development of specialized trauma centers, trauma-specific intensive care units, and trauma-focused medical subspecialties has led to the formation of comprehensive multidisciplinary teams and an ever-growing body of research and innovation. The field of interventional radiology provides a unique set of minimally invasive, endovascular techniques that has largely changed the way that many trauma patients are managed. This article discusses the role of interventional radiology in the care of this complex patient population, and in particular how the specialty fits into the overall team management of these patients.
RESUMEN
BACKGROUND: A minimally invasive step-up approach to necrotizing biliary pancreatitis often requires multiple interventions, delaying cholecystectomy. The risk of gallstone-related complications during this time interval is unknown, as is the feasibility and safety of cholecystectomy after minimally invasive step-up treatment. In this paper, we analyzed both. METHODS: Necrotizing pancreatitis patients treated with a minimally invasive step-up approach who underwent interval cholecystectomy at 2 tertiary care centers between 2014 and 2019 were included. Gallstone-related complications prior to cholecystectomy were examined, as were surgical approaches to cholecystectomy and complications. Necrotizing pancreatitis patients treated without mechanical intervention were also examined. RESULTS: Seven of 31 patients developed gallstone-related complications between minimally invasive step-up treatment initiation and cholecystectomy. One patient developed biliary colic. Six patients developed acute cholecystitis. Two of these patients also developed choledocholithiasis, and 1 developed cholangitis, all requiring endoscopic retrograde cholangiopancreatography. Cholecystectomy was performed laparoscopically in 27 of 31 patients. One patient required open conversion, and 3 patients underwent planned cholecystectomy during another open operation. Four patients developed postoperative complications. Two of 14 necrotizing pancreatitis patients treated without mechanical intervention developed recurrent pancreatitis while awaiting cholecystectomy. CONCLUSION: Over 20% of necrotizing pancreatitis patients treated by a minimally invasive step-up approach developed gallstone-related complications while awaiting cholecystectomy. Laparoscopic cholecystectomy is feasible and safe in the great majority of necrotizing pancreatitis patients treated by a minimally invasive step-up approach.

BACKGROUND: Prehospital tourniquet (PHT) utilization has increased in response to mass casualty events. We aimed to describe the incidence, therapeutic effectiveness, and morbidity associated with tourniquet placement in all patients treated with PHT application. METHODS: A retrospective observational cohort study was performed to evaluate all adults with a PHT who presented at two Level I trauma centers between January 2015 and December 2019. Medically trained abstractors determined if the PHT was clinically indicated (placed for limb amputation, vascular hard signs, injury requiring hemostasis procedure, or significant documented blood loss). Prehospital tourniquets were further designated as appropriately or inappropriately applied (based on PHT anatomic placement location, occurrence of a venous tourniquet, or ischemic time defined as >2 hours). Statistical analyses were performed to generate primary and secondary results. RESULTS: A total of 147 patients met study inclusion criteria, of which 70% met the criteria for trauma registry inclusion. Total incidence of PHT utilization increased from 2015 to 2019, with increasing proportions of PHTs placed by nonemergency medical service personnel. Improvised PHTs were frequently used. Prehospital tourniquets were clinically indicated in 51% of patients. Overall, 39 (27%) patients had a PHT that was inappropriately placed, five of which resulted in significant morbidity. CONCLUSION: In summary, prehospital tourniquet application has become widely adopted in the civilian setting, frequently performed by civilian and nonemergency medical service personnel. Of PHTs placed, nearly half had no clear indication for placement and over a quarter of PHTs were misapplied with notable associated morbidity. Results suggest that the topics of clinical indication and appropriate application of tourniquets may be important areas for continued focus in future tourniquet educational programs, as well as future quality assessment efforts. LEVEL OF EVIDENCE: Epidemiological, level III; Therapeutic, level IV.

BACKGROUND: A minimally invasive step-up (MIS) approach has been associated with reduced morbidity compared with open surgical necrosectomy (OSN) for treatment of necrotizing pancreatitis. We sought to determine whether transitioning from an OSN to an MIS-based approach would result in reduced mortality. MIS interventions included percutaneous drainage, endoscopic transgastric necrosectomy, video-assisted retroperitoneal debridement, sinus tract endoscopic necrosectomy, or a combination of techniques, with selective use of OSN. STUDY DESIGN: We conducted an observational cohort study with retrospective comparison at a single tertiary referral center (2006 through 2019). Eighty-eight patients were treated with OSN and 91 were treated with an MIS-based approach. Baseline characteristics and clinical outcomes were compared between groups. The primary end point was 90-day mortality. RESULTS: There was no difference in baseline characteristics. Ninety-day mortality was 2% with MIS compared with 10% with OSN (p = 0.03). One-year mortality was 3% with MIS compared with 15% with OSN (p = 0.012). The rate of organ failure was lower with MIS (30% vs 45%; p = 0.029), but there was a higher bleeding rate (19% vs 9%; p = 0.064). In the MIS group, 9% were treated with percutaneous drainage, 32% with endoscopic transgastric necrosectomy, 8% with video-assisted retroperitoneal debridement, 15% with sinus tract endoscopic necrosectomy, and 27% with a combination of techniques. CONCLUSIONS: Adoption of a multidisciplinary MIS-based approach to necrotizing pancreatitis resulted in a 5-fold decrease in mortality compared with OSN.

PURPOSE: Critically ill patients with Coronavirus Disease 2019 (COVID-19) have high rates of line thrombosis. Our objective was to examine the safety and efficacy of a low dose heparinized saline (LDHS) arterial line (a-line) patency protocol in this population. MATERIALS AND METHODS: In this observational cohort study, patients ≥18 years with COVID-19 admitted to an ICU at one institution from March 20-May 25, 2020 were divided into two cohorts. Pre-LDHS patients had an episode of a-line thrombosis between March 20-April 19. Post-LDHS patients had an episode of a-line thrombosis between April 20-May 25 and received an LDHS solution (10 units/h) through their a-line pressure bag. RESULTS: Forty-one patients (pre-LDHS) and 30 patients (post-LDHS) were identified. Baseline characteristics were similar between groups, including age (61 versus 54 years; p = 0.24), median Sequential Organ Failure Assessment score (6 versus 7; p = 0.67) and systemic anticoagulation (47% versus 32%; p = 0.32). Median duration of a-line patency was significantly longer in post-LDHS versus pre-LDHS patients (8.5 versus 2.9 days; p < 0.001). The incidence of bleeding complications was similar between cohorts (13% vs. 10%; p = 0.71). CONCLUSIONS: A LDHS protocol was associated with a clinically significant improvement in a-line patency duration in COVID-19 patients, without increased bleeding risk.

Classically, hepatic artery pseudoaneurysms (HAPs) arise secondary to trauma or iatrogenic causes. With an increasing prevalence of laparoscopic procedures of the hepatobiliary system the risk of inadvertent injury to arterial vessels is increased. Pseudoaneurysm formation post injury can lead to serious consequences of rupture and subsequent hemorrhage, therefore intervention in all identified visceral pseudoaneurysms has been advocated. A variety of interventional methods have been proposed, with surgical management becoming the last step intervention when minimally invasive therapies have failed. The authors present a case of a HAP in a 56-year-old female presenting with jaundice and pruritis suggestive of a Klatskin's tumor. This presentation of HAP in a patient without any significant past medical or surgical intervention is atypical when considering that the majority of HAP cases present secondary to iatrogenic causes or trauma. Multiple minimally invasive approaches were employed in an attempt to alleviate the symptomology which included jaundice and associated inflammatory changes. Ultimately, a right hepatic trisegmentectomy was required to adequately relieve the mass effect on biliary outflow obstruction and definitively address the HAP. The presentation of a HAP masquerading as a malignancy with jaundice and pruritis, rather than the classic symptoms of abdominal pain, anemia, and melena, is unique. This presentation is only further complicated by the absent history of either trauma or instrumentation. It is important to be aware of HAPs as a potential cause of jaundice in addition to the more commonly thought of etiologies. Furthermore, given the morbidity and mortality associated with pseudoaneurysm rupture, intervention in identifiable cases, either by minimally invasive or surgical interventions, is recommended.
RESUMEN
BACKGROUND: Data are sparse regarding patient selection criteria or evaluating oncologic outcomes following laparoscopic pancreaticoduodenectomy (LPD). Having prospectively limited LPD to patients with resectable disease defined by National Comprehensive Cancer Network (NCCN) criteria, we evaluated perioperative and long-term oncologic outcomes of LPD compared to a similar cohort of open pancreaticoduodenectomy (OPD). METHODS: Consecutive patients (November 2010-February 2014) undergoing pancreaticoduodenectomy (PD) for periampullary adenocarcinoma were reviewed. Patients were excluded from further analysis for benign pathology, conversion to OPD for portal vein resection, and contraindications for LPD not related to their malignancy. Outcomes of patients undergoing LPD were analyzed in an intention-to-treat manner against a cohort of patients undergoing OPD. RESULTS: These selection criteria resulted in offering LPD to 77 % of all cancer patients. Compared to the OPD cohort, LPD was associated with significant reductions in wound infections (16 vs. 34 %; P = 0.038), pancreatic fistula (17 vs. 36 %; P = 0.032), and median hospital stay (9 vs. 12 days; P = 0.025). Overall survival (OS) was not statistically different between patients undergoing LPD vs. OPD for periampullary adenocarcinoma (median OS 27.9 vs. 23.5 months; P = 0.955) or pancreatic adenocarcinoma (N = 28 vs. 22 patients; median OS 20.7 vs. 21.1 months; P = 0.703). CONCLUSIONS: The selective application of LPD for periampullary malignancies results in a high degree of eligibility as well as significant reductions in length of stay, wound infections, and pancreatic fistula. Overall survival after LPD is similar to OPD.
