Early Detection of Ventilator-associated Pneumonia From Exhaled Breath in Intensive Care Unit Patients.

OBJECTIVE: Evaluate associations between volatile organic compounds (VOCs) in heat and moisture exchange (HME) filters and the presence of ventilator-associated pneumonia (VAP). BACKGROUND: Clinical diagnostic criteria for VAP have poor interobserver reliability, and cultures are slow to result. Exhaled breath contains VOCs related to gram-negative bacterial proliferation, the most identified organisms in VAP. We hypothesized that exhaled VOCs on HME filters can predict nascent VAP in mechanically ventilated intensive care unit patients. METHODS: Gas chromatography-mass spectrometry was used to analyze 111 HME filters from 12 intubated patients who developed VAP. Identities and relative amounts of VOCs were associated with dates of clinical suspicion and culture confirmation of VAP. Matched pairs t tests were performed to compare VOC abundances in HME filters collected within 3 days pre and postclinical suspicion of VAP (pneumonia days), versus outside of these days (non-pneumonia days). A receiver operating characteristic curve was generated to determine the diagnostic potential of VOCs. RESULTS: Carbon disulfide, associated with the proliferation of certain gram-negative bacteria, was found in samples collected during pneumonia days for 11 of 12 patients. Carbon disulfide levels were significantly greater ( P = 0.0163) for filters on pneumonia days. The Area Under the Curve of the Reciever Operating Characteristic curve (AUC ROC) for carbon disulfide was 0.649 (95% CI: 0.419-0.88). CONCLUSIONS: Carbon disulfide associated with gram-negative VAP can be identified on HME filters up to 3 days before the initial clinical suspicion, and approximately a week before culture confirmation. This suggests VOC sensors may have potential as an adjunctive method for early detection of VAP.

Optimal Timing for Initiation of Thromboprophylaxis After Hepatic Angioembolization.

OBJECTIVE: To evaluate the optimal timing of thromboprophylaxis (TPX) initiation after hepatic angioembolization in trauma patients. BACKGROUND: TPX after hepatic trauma is complicated by the risk of bleeding, but the relative risk after hepatic angioembolization is unknown. METHODS: Patients who underwent hepatic angioembolization within 24 hours were retrospectively identified from the 2017 to 2019 American College of Surgeons Trauma Quality Improvement Project data sets. Cases with <24-hour length of stay and other serious injuries were excluded. Venous thromboembolism (VTE) included deep venous thrombosis and PE. Bleeding complications included hepatic surgery, additional angioembolization, or blood transfusion after TPX initiation. Differences were tested with univariate and multivariate analyses. RESULTS: Of 1550 patients, 1370 had initial angioembolization. Bleeding complications were higher in those with TPX initiation within 24 hours (20.0% vs 8.9%, P <0.001) and 48 hours (13.2% vs 8.4%, P =0.013). However, VTE was higher in those with TPX initiation after 48 hours (6.3% vs 3.3%, P =0.025). In the 180 patients with hepatic surgery before angioembolization, bleeding complications were higher in those with TPX initiation within 24 hours (72% vs 20%, P <0.001), 48 hours (50% vs 17%, P <0.001), and 72 hours (37% vs 14%, P =0.001). Moreover, deep venous thrombosis was higher in those with TPX initiation after 96 hours (14.3% vs 3.1%, P =0.023). CONCLUSIONS: This is the first study to address the timing of TPX after hepatic angioembolization in a national sample of trauma patients. For these patients, initiation of TPX at 48 to 72 hours achieves the safest balance in minimizing bleeding while reducing the risk of VTE. LEVEL OF EVIDENCE: Level III-retrospective cohort study.

The Enigma That is Rectal Squamous Cell Carcinoma: A Case Series.

INTRODUCTION: Colorectal cancer is the third most common cancer and the third leading cause of cancer deaths in the United States. As rectal squamous cell carcinoma (SCC) is an uncommon colorectal cancer, there is limited data on this clinical entity. We aimed to evaluate the tumor characteristics, treatment, and clinical outcomes of this rare deadly disease. METHODS: Pathological specimens from 2017 to 2022 at a single National Cancer Institute-designated cancer center were screened for all rectal cases with a diagnosis of SCC. All patients with a primary rectal SCC were included. Patients who had extension to the dentate line or evidence of an anal mass, and those who were treated at an outside institution, were excluded. Demographic, treatment, outcome, and surveillance data was extracted. RESULTS: There were 56 specimens identified, nine of which met inclusion criteria. Most patients were White (78%), Hispanic (78%), and female (67%). The average age at diagnosis was 57 y [52-65]. All patients had nodal involvement at the time of clinical staging. All patients were treated with Nigro protocol, with one patient treated with surgery first. The median time of follow-up was 12 mo after initial treatment, 33% had recurrence, with median time to recurrence of 25 mo. Overall, mortality from rectal SCC was 33% at a median time of 37 mo from initial diagnosis. CONCLUSIONS: Rectal SCC is a colorectal cancer that is not fully understood. Our findings showed that treatment mirrors that of anal SCC, with similar rates of survival to both rectal adenocarcinoma and anal SCC.

Initial Hemorrhage Control Procedure for Splenic Injuries May Affect Risk of Venous Thromboembolism.

INTRODUCTION: Venous thromboembolism (VTE) continues to be a major cause of morbidity in trauma. It is unclear whether the type of hemorrhage control procedure (i.e., splenectomy versus angioembolization) is associated with an increased risk of VTE. We hypothesize that hemodynamically stable patients undergoing angioembolization for blunt high-grade splenic injuries have lower rates of VTE compared to those undergoing splenectomy. METHODS: The American College of Surgeons Trauma Quality Program dataset from 2017 to 2019 was queried to identify all patients with American Association for the Surgery of Trauma grade 3-5 blunt splenic injuries. Outcomes including VTE rates were compared between those who were managed with splenectomy versus angioembolization. Propensity score matching (1:1) was performed adjusting for age, sex, initial vital signs, Injury Severity Score, and splenic injury grade. RESULTS: The analysis included 4698 matched patients (splenectomy [n = 2349] and angioembolization [n = 2349]). The median (interquartile range) age was 41 (27-58) years and 69% were male. Patients were well matched between groups. Angioembolization was associated with significantly lower VTE than splenectomy (2.2% versus 3.4%, P = 0.010) despite less use of VTE chemoprophylaxis (70% versus 80%, P < 0.001), as well as a relative delay in initiation of chemoprophylaxis (44 h versus 33 h, P < 0.001). Hospital and intensive care unit length of stay and mortality were also significantly lower in the angioembolization group. CONCLUSIONS: Angioembolization is associated with a significantly lower incidence of VTE than splenectomy. Thus, angioembolization should be considered for initial management of hemodynamically stable patients with high-grade blunt splenic injuries in whom laparotomy is not otherwise indicated.

Nationwide Analysis of Firearm Injury Versus Other Penetrating Trauma: It's Not All the Same Caliber.

INTRODUCTION: Ballistic injuries cause both a temporary and permanent cavitation event, making them far more destructive and complex than other penetrating trauma. We hypothesized that global injury scoring and physiologic parameters would fail to capture the lethality of gunshot wounds (GSW) compared to other penetrating mechanisms. METHODS: The 2019 American College of Surgeons Trauma Quality Programs participant use file was queried for the mortality rate for GSW and other penetrating mechanisms. A binomial logistic regression model ascertained the effects of sex, age, hypotension, tachycardia, mechanism, Glasgow Coma Scale, ISS, and volume of blood transfusion on the likelihood of mortality. Subgroup analyses examined isolated injuries by body regions. RESULTS: Among 95,458 cases (82% male), GSW comprised 46.4% of penetrating traumas. GSW was associated with longer hospital length of stay (4 [2-9] versus 3 [2-5] days), longer intensive care unit length of stay (3 [2-6] versus 2 [2-4] days), and more ventilator days (2 [1-4] versus 2 [1-3]) compared to stab wounds, all P < 0.001. The model determined that GSW was linked to increased odds of mortality compared to stab wounds (odds ratio 4.19, 95% confidence interval 3.55-4.93). GSW was an independent risk factor for acute kidney injury, acute respiratory distress syndrome, venous thromboembolism, sepsis, and surgical site infection. CONCLUSIONS: Injury scoring systems based on anatomical or physiological derangements fail to capture the lethality of GSW compared to other mechanisms of penetrating injury. Adjustments in risk stratification and reporting are necessary to reflect the proportion of GSW seen at each trauma center. Improved classification may help providers develop quality processes of care. This information may also help shape public discourse on this highly lethal mechanism.

Survival of In-Hospital Cardiopulmonary Arrest in Trauma Patients.

INTRODUCTION: Relative to other hospitalized patients, trauma patients are younger with fewer comorbidities, but the incidence and outcomes of in-hospital cardiopulmonary arrest (IHCA) with cardiopulmonary resuscitation (CPR) in this population is unknown. Therefore, we aimed to investigate factors associated with survival in trauma patients after IHCA to test the hypothesis that compared to other hospitalized patients, trauma patients with IHCA have improved survival. METHODS: Retrospective review of the Trauma Quality Improvement Program database 2017 to 2019 for patients who had IHCA with CPR. Primary outcome was survival to hospital discharge. Secondary outcomes were in-hospital complications, hospital length of stay, intensive care unit length of stay, and ventilator days. Data were compared with univariate and multivariate analyses at P < 0.05. RESULTS: In 22,346,677 admitted trauma patients, 14,056 (0.6%) received CPR. Four thousand three hundred seventy-seven (31.1%) survived to discharge versus 26.4% in a national sample of all hospitalized patients (P < 0.001). In trauma patients, median age was 55 y, the majority were male (72.2%). Mortality was higher for females versus males (70.3% versus 68.3%, P = 0.026). Multivariate regression showed that older age 1.01 (95% confidence interval (CI) 1.01-1.02), Hispanic ethnicity 1.21 (95% CI 1.04-1.40), and penetrating trauma 1.51 (95% CI 1.32-1.72) were risk factors for mortality, while White race was a protective factor 0.36 (95% CI 0.14-0.89). CONCLUSIONS: This is the first study to show that the incidence of IHCA with CPR is approximately six in 1000 trauma admissions and 31% survive to hospital discharge, which is higher than other hospitalized patients. Age, gender, racial, and ethnic disparities also influence survival.

Timing of Pediatric Incarcerated Inguinal Hernia Repair: A Review of Nationwide Readmissions Data.

INTRODUCTION: In pediatric patients, incarcerated inguinal hernias are often repaired on presentation. We hypothesize that in appropriate patients, repair may be safely deferred. METHODS: The Nationwide Readmissions Database was used to identify pediatric patients (aged < 18 y) with incarcerated inguinal hernia from 2010 to 2014. Patients were stratified by management approach (Early Repair versus Deferral). Overall frequencies of these operative strategies were calculated. Propensity score matching was then performed to control for patient age, comorbidities, perinatal conditions, and congenital anomalies. Outcomes including complications, surgical procedures, and readmissions were compared. Outpatient surgeries were not assessed. RESULTS: Among 6148 total patients with incarcerated inguinal hernia, the most common strategy was to perform Early Repair (88% versus 12% Deferral). Following propensity score matching, the cohort included 1288 patients (86% male, average age 1.7 ± 4.1 years). Deferral was associated with equivalent rates of readmission within one year (13% versus 15%, P = 0.143), but higher readmissions within the first 30 days (7% versus 3%, P = 0.002) than Early Repair. Deferral patients had lower rates of orchiectomy (2% versus 5%, P = 0.001), wound infections (< 2% versus 2%, P = 0.020), and other infections (7% versus 15%, P < 0.001). The frequency of other complications including bowel resection, oophorectomy, testicular atrophy, sepsis, and pneumonia were equivalent between groups. Three percent of Deferrals had a diagnosis of incarceration on readmission. CONCLUSIONS: Deferral of incarcerated inguinal hernia repair at index admission is associated with higher rates of hospital readmissions within the first 30 days but equivalent readmission within the entire calendar year. These patients are at risk of repeat incarceration but have significantly lower rates of orchiectomy than their counterparts who undergo inguinal hernia repair at the index admission. We propose that prospective studies be performed to identify good candidates for Elective Deferral following manual reduction and overnight observation. Such studies must capture outpatient surgical outcomes.

Robotic Versus Laparoscopic Ventral Hernia Repair: Two-Year Results From a Prospective, Multicenter, Blinded Randomized Clinical Trial.

OBJECTIVE: Report the 2-year outcomes of a multicenter randomized controlled trial comparing robotic versus laparoscopic intraperitoneal onlay mesh ventral hernia repair. BACKGROUND: Ventral hernia repair is one of the most common operations performed by general surgeons. To our knowledge, no studies have been published to date comparing long-term outcomes of laparoscopic versus robotic ventral hernia repair. METHODS: The trial was registered at clinicaltrials.gov (NCT03490266). Clinical outcomes included surgical site infection, surgical site occurrence, hernia occurrence, readmission, reoperation, and mortality. RESULTS: A total of 175 consecutive patients were approached that were deemed eligible for elective minimally invasive ventral hernia repair. In all, 124 were randomized and 101 completed follow-up at 2 years. Two-year follow-up was completed in 54 patients (83%) in the robotic arm and 47 patients (80%) in the laparoscopic arm. No differences were seen in surgical site infection or surgical site occurrence. Hernia recurrence occurred in 2 patients (4%) receiving robotic repair versus in 6 patients (13%) receiving laparoscopic repair (relative risk: 0.3, 95% CI: 0.06-1.39; P =0.12). No patients (0%) required reoperation in the robotic arm whereas 5 patients (11%) underwent reoperation in the laparoscopic arm ( P =0.019, relative risk not calculatable due to null outcome). CONCLUSIONS: Robotic ventral hernia repair demonstrated at least similar if not improved outcomes at 2 years compared with laparoscopy. There is potential benefit with robotic repair; however, additional multi-center trials and longer follow-up are needed to validate the hypothesis-generating findings of this study.

Mesh Type With Ventral Hernia Repair: A Systematic Review and Meta-analysis of Randomized Trials.

INTRODUCTION: Synthetic mesh is widely utilized for clean ventral hernia repair; however, it is unclear if synthetic mesh provides the same benefits with high-risk patients or during contaminated cases. Many surgeons use biologic mesh in these settings, but there is little evidence to support this practice. Our objective was to compare the clinical outcomes of utilizing biologic mesh versus synthetic mesh during ventral hernia repair. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, a review of the literature was conducted using Cochrane library, EMBASE, Clinicaltrials.gov, and PubMed for randomized controlled trials published that compared biologic versus synthetic mesh during ventral hernia repair. The primary outcome was major complications defined as deep or organ space surgical site infection, reoperations, and hernia recurrences. RESULTS: Of 1889 manuscripts screened, four publications were included. The four studies included a total of 758 patients, with 381 receiving biologic mesh and 377 receiving synthetic mesh. Compared to biologic mesh, synthetic mesh had lower rates of major complications (38.6% versus 23.4, risk ratio = 0.55, 95% confidence interval = 0.35 to 0.86, P = 0.009) and hernia recurrence (24.5 % versus 10.3%, risk ratio = 0.44, 95% confidence interval = 0.28 to 0.69, P = 0.004). In addition, there was a lower percentage of surgical site infection and reoperation in the synthetic mesh group. CONCLUSIONS: Contrary to current surgical teaching, placement of permanent synthetic mesh into a contaminated field yielded rates of complications that were comparable or reduced compared to biologic mesh.

The Evidence Behind Robot-Assisted Abdominopelvic Surgery : A Systematic Review.

BACKGROUND: Use of robot-assisted surgery has increased dramatically since its advent in the 1980s, and nearly all surgical subspecialties have adopted it. However, whether it has advantages compared with laparoscopy or open surgery is unknown. PURPOSE: To assess the quality of evidence and outcomes of robot-assisted surgery compared with laparoscopy and open surgery in adults. DATA SOURCES: PubMed, EMBASE, Scopus, and the Cochrane Central Register of Controlled Trials were searched from inception to April 2021. STUDY SELECTION: Randomized controlled trials that compared robot-assisted abdominopelvic surgery with laparoscopy, open surgery, or both. DATA EXTRACTION: Two reviewers independently extracted study data and risk of bias. DATA SYNTHESIS: A total of 50 studies with 4898 patients were included. Of the 39 studies that reported incidence of Clavien-Dindo complications, 4 (10%) showed fewer complications with robot-assisted surgery. The majority of studies showed no difference in intraoperative complications, conversion rates, and long-term outcomes. Overall, robot-assisted surgery had longer operative duration than laparoscopy, but no obvious difference was seen versus open surgery. LIMITATIONS: Heterogeneity was present among and within the included surgical subspecialties, which precluded meta-analysis. Several trials may not have been powered to assess relevant differences in outcomes. CONCLUSION: There is currently no clear advantage with existing robotic platforms, which are costly and increase operative duration. With refinement, competition, and cost reduction, future versions have the potential to improve clinical outcomes without the existing disadvantages. PRIMARY FUNDING SOURCE: None.

Prevalence and Impact on Quality of Life of Occult Hernias among Patients Undergoing Computed Tomography.

BACKGROUND: With the widespread use of advanced imaging there is a need to quantify the prevalence and impact of hernias. We aimed to determine the prevalence of abdominal wall hernias among patients undergoing computed tomography (CT) scans and their impact on abdominal wall quality of life (AW-QOL). METHODS: Patients undergoing elective CT abdomen/pelvis scans were enrolled. Standardized physical examinations were performed by surgeons blinded to the CT scan results. AW-QOL was measured through the modified Activities Assessment Scale. On this scale, 1 is poor AW-QOL, 100 is perfect, and a change of 7 is the minimum clinically important difference. Three surgeons reviewed the CT scans for the presence of ventral or groin hernias. The number of patients and the median AW-QOL scores were determined for three groups: no hernia, hernias only seen on imaging (occult hernias), and clinically apparent hernias. RESULTS: A total of 246 patients were enrolled. Physical examination detected 62 (25.2%) patients with a hernia while CT scan revealed 107 (43.5%) with occult hernias. The median (interquartile range) AW-QOL of patients per group was no hernia = 84 (46), occult hernia = 77 (57), and clinically apparent hernia = 62 (55). CONCLUSIONS: One-fourth of individuals undergoing CT abdomen/pelvis scans have a clinical hernia, whereas nearly half have an occult hernia. Compared with individuals with no hernias, patients with clinically apparent or occult hernias have a lower AW-QOL (by 22 and seven points, respectively). Further studies are needed to determine natural history of AW-QOL and best treatment strategies for patients with occult hernias.

Lack of Regulations and Conflict of Interest Transparency of New Hernia Surgery Technologies.

BACKGROUND: Medical devices introduced to market through the 510K process often have limited research of low quality and substantial conflict of interest (COI). By the time high-quality safety and effectiveness research is performed, thousands of patients may have already been treated by the device. Our aim was to systematically review the trends of outcomes, research quality, and financial relationships of published studies related to de-adopted meshes for ventral hernia repair. MATERIALS AND METHODS: Literature was systematically reviewed using PubMed to obtain all published studies related to three de-adopted meshes: C-QUR, Physiomesh, and meshes with polytetrafluoroethylene. Primary outcome was change in cumulative percentage of subjects with positive published outcomes. Secondary outcome was percentage of published manuscript with COI. RESULTS: A total of 723 articles were screened, of which, 129 were analyzed and included a total of 8081 subjects. Percentage of subjects with positive outcomes decreased over time for all groups: (1) C-QUR from 100% in 2009 to 22% in 2018, (2) Physiomesh from 100% in 2011 to 20% in 2018, and (3) polytetrafluoroethylene from 100% in 1979 to 49% in 2018. Authors of only 20% of articles self-reported no COI, most representing later publications and were more likely to show neutral or negative results. CONCLUSIONS: Among three de-adopted meshes, early publications demonstrated overly optimistic results followed by disappointing outcomes. Skepticism over newly introduced, poorly proven therapies is essential to prevent adoption of misleading practices and products. Devices currently approved under the 510K processes should undergo blinded, randomized controlled trials before introduction to the market.

Gender Disparity Among Surgical Peer-Reviewed Literature.

BACKGROUND: Women remain under-represented in academic surgery despite increasing percentages of female surgeons and surgery residents. Publications and leadership positions are used for hiring and promoting academic surgeons. We sought to determine the disparity of female authorship when compared with male authors in surgical peer-reviewed publications. METHODS: PubMed was searched for surgical publications from the United States. Obstetrics and gynecology was selected as a control specialty owing to its history of high female representation. Thirteen other surgical specialties were randomly selected from the Accreditation Council for Graduate Medical Education specialty list. Manuscripts from four time periods, 2000-2005, 2006-2010, 2011-2015, and 2016-2017, were randomly selected, and the gender of the first and last authors was determined. The Accreditation Council for Graduate Medical Education and Association of American Medical Colleges databases were used to determine women representation in surgery. Trends were assessed using the Cochran-Armitage test. RESULTS: In total, 560 manuscripts in 14 specialties were reviewed. In the control specialty, 51% of first authors were female compared with 18% of those in study specialties, and 39% of last authors were female compared with 11% of those in study specialties. No difference was found when comparing the gender of first (P-value = 0.393) and/or last authors (P-value = 0.281) with the proportion of female residents and attendings. CONCLUSIONS: Women surgeons publish research at a rate proportional to the number of females involved in that specialty. Disparities in leadership roles are unlikely explained by differences in publications. Instead, disparities are likely due to other reasons such as failure to attract women to academic surgery and failure to promote and mentor women surgeons into leadership positions.

Are online surgical discussion boards a safe and useful venue for surgeons to ask for advice? A review of the International Hernia Collaboration Facebook Group.

BACKGROUND: Social media is a growing medium for disseminating information among surgeons. The International Hernia Collaboration Facebook Group (IHC) is a widely utilized social media platform to share ideas and advice on managing patients with hernia-related diseases. Our objective was to assess the safety and utility of advice provided. METHODS: Overall, 60 consecutive de-identified clinical threads were extracted from the IHC in reverse chronological order. A group of three hernia specialists evaluated all threads for unsafe posts, unhelpful comments, and if an established evidence-based management strategy was provided. Positive and negative controls for safe and unsafe answers were included in seven threads and reviewers were blinded to their presence. Reviewers were free to access all online and professional resources (except the IHC). RESULTS: There were 598 unique responses (median 10, 1-26 responses per thread) to the 60 clinical threads/scenarios. The review team correctly identified all seven positive and negative controls. Most responses were safe (96.6%) but some were unhelpful (28.4%). For sixteen threads, the reviewers believed there was an established evidence-based answer; however, only six were provided. In addition, 14 responses were considered unsafe, but only four were corrected. CONCLUSIONS: The vast majority of responses were considered helpful; however, evidence-based management is typically not provided and unsafe recommendations often go uncontested. While the IHC allows wide dissemination of hernia-related surgical advice/discussions, surgeons should be cautious when using the IHC for clinical advice. Mechanisms to provide evidence-based management strategies and to identify unsafe advice are needed to improve quality within online forums and to prevent patient harm.

Expectant Management of Patients with Ventral Hernias: 3 Years of Follow-up.

BACKGROUND: The safety and effectiveness of expectant management (e.g., watchful waiting or initially managing non-operatively) for patients with a ventral hernia is unknown. We report our 3-year results of a prospective cohort of patients with ventral hernias who underwent expectant management. METHODS: A hernia clinic at an academic safety-net hospital was used to recruit patients. Any patient undergoing expectant management with symptoms and high-risk comorbidities, as determined by a surgeon based on institutional criteria, would be included in the study. Patients unlikely to complete follow-up assessments were excluded from the study. Patient-reported outcomes were collected by phone and mailed surveys. A modified activities assessment scale normalized to a 1-100 scale was used to measure results. The rate of operative repair was the primary outcome, while secondary outcomes include rate of emergency room (ER) visits and both emergent and elective hernia repairs. RESULTS: Among 128 patients initially enrolled, 84 (65.6%) completed the follow-up at a median (interquartile range) of 34.1 (31, 36.2) months. Overall, 28 (33.3%) patients visited the ER at least once because of their hernia and 31 (36.9%) patients underwent operative management. Seven patients (8.3%) required emergent operative repair. There was no significant change in quality of life for those managed non-operatively; however, substantial improvements in quality of life were observed for patients who underwent operative management. CONCLUSIONS: Expectant management is an effective strategy for patients with ventral hernias and significant comorbid medical conditions. Since the short-term risk of needing emergency hernia repair is moderate, there could be a safe period of time for preoperative optimization and risk-reduction for patients deemed high risk.

Immediate Versus Delayed Surgical Management of Infant Cryptorchidism With Inguinal Hernia.

INTRODUCTION: Cryptorchidism is commonly treated with orchiopexy at 6-12 months of age, often allowing time for undescended testicle(s) (UT) to descend spontaneously. However, when an inguinal hernia (IH) is also present, some surgeons perform orchiopexy and inguinal hernia repair (IHR) immediately rather than delaying surgery. We hypothesize that early surgical intervention provides no benefit for newborns with both IH and UT. METHODS: The Nationwide Readmissions Database was used to identify newborns with diagnoses of both IH and UT from 2010 to 2014. Patients were stratified by management: IHR performed on initial admission (Repair) or not (Deferral). Demographics, outcomes, and complications were compared. Results were weighted for national estimates. RESULTS: We analyzed 1306 newborns (64% premature) diagnosed with both IH and UT. IHR was performed at index admission in 30%. Repair was more common in premature babies (43% vs. 8% full-term, p < 0.001) and patients with congenital anomalies (33% vs. 27% without congenital anomaly, p = 0.012). There was no difference in readmission rates. Repair patients had higher rates of orchiectomy than did Deferral. No Deferral patients were readmitted for bowel resection, and <1% were readmitted for orchiectomy or hernia incarceration. CONCLUSION: In newborns with UT and IH, immediate repair is not associated with improved outcomes. Even with incarceration on initial presentation, rates of readmission with incarceration or bowel compromise for patients who undergo Deferral of surgery are minimal. Moreover, Repair newborns have higher rates of orchiectomy. We found no benefit to early operative intervention; thus, we recommend waiting until 6-12 months of age to reassess for surgery. LEVEL OF EVIDENCE: Level III TYPE OF STUDY: Retrospective Comparative Study.

Adequate Reporting Among Ventral Hernia Repair Operative Reports: A Cross-Sectional Study of Prevalence of Details and Association With Clinical Outcomes.

Objective: We aimed to evaluate the prevalence of highly detailed ventral hernia repair (VHR) operative reports and associations between operative report detail and postoperative outcomes in a medico-legal dataset. Background: VHR are one of the most common surgical procedures performed in the United States. Previous work has shown that VHR operative reports are poorly detailed, however, the relationship between operative report detail and patient outcomes is unknown. Methods: This is a retrospective cross-sectional observational study. Operative reports describing VHR were obtained from a medical-legal database. Medical records were screened and data was extracted including clinical outcomes, such as surgical site infection (SSI), hernia recurrence, and reoperation and the presence of key details in each report. Highly detailed operative reports were defined as having 70% of recommended details. The primary outcome was the prevalence of highly detailed VHR operative reports. Results: A total of 1011 VHR operative reports dictated by 693 surgeons across 517 facilities in 50 states were included. Median duration of follow-up was 4.6 years after initial surgery. Only 35.7% of operative reports were highly detailed. More recent operative reports, cases with resident involvement, and contaminated procedures were more likely to be highly detailed (all P < 0.05). Compared to poorly detailed operative reports, cases with highly detailed reports had fewer SSIs (13.2% vs 7.5%, P = 0.006), hernia recurrence (65.8% vs 55.4%, P = 0.002), and reoperation (78.9% vs 62.6%, P = 0.001). Conclusions: In this medico-legal dataset, most VHR operative reports are poorly detailed while highly detailed operative reports were associated with lower rates of complications. Future studies should examine a nationally representative dataset to validate our findings.

A 20-year retrospective analysis of deep venous thrombosis and pulmonary embolism among combat casualties requiring damage-control laparotomy at US military Role 2 surgical units.

BACKGROUND: Combat casualties receiving damage-control laparotomy at forward deployed, resource-constrained US military Role 2 (R2) surgical units require multiple evacuations, but the added risk of venous thromboembolism (VTE) in this population has not been defined. To fill this gap, we retrospectively analyzed 20 years of Department of Defense Trauma Registry data to define the VTE rate in this population. METHODS: Department of Defense Trauma Registry from 2002 to 2023 was queried for US military combat casualties requiring damage-control laparotomy at R2. All deaths were excluded in subsequent analysis. Rates of VTE were assessed, and subgroup analysis was performed on patients requiring massive transfusion. RESULTS: Department of Defense Trauma Registry (n = 288) patients were young (mean age, 25 years) and predominantly male (98%) with severe (mean Injury Severity Score, 26), mostly penetrating injury (76%) and high mortality. Venous thromboembolism rate was high: 15.8% (DVT, 10.3%; pulmonary embolism, 7.1%). In the massively transfused population, the VTE rate was even higher (26.7% vs. 10.2%, p < 0.001). CONCLUSION: This is the first report that combat casualties requiring damage-control laparotomy at R2 have such high VTE rates. Therefore, for military casualties, we propose screening ultrasound upon arrival to each subsequent capable echelon of care and low threshold for initiating thromboprophylaxis. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.
