RESUMEN

BACKGROUND: Underrepresented minority patients with surgical malignancies experience disparities in outcomes. The impact of provider-based factors, including communication, trust, and cultural competency, on outcomes is not well understood. This study examines modifiable provider-based barriers to care experienced by patients with surgical malignancies. METHODS: A parallel, prospective, mixed-methods study enrolled patients with lung or gastrointestinal malignancies undergoing surgical consultation. Surveys assessed patients' social needs and patient-physician relationship. Semi-structured interviews ascertained patient experiences and were iteratively analyzed, identifying key themes. RESULTS: The cohort included 24 patients (age 62 years; 63% White and 38% Black/African American). The most common cancers were lung (n = 18, 75%) and gastroesophageal (n = 3, 13%). Survey results indicated that food insecurity (n = 5, 21%), lack of reliable transportation (n = 4, 17%), and housing instability (n = 2, 8%) were common. Lack of trust in their physician (n = 3, 13%) and their physician's treatment recommendation (n = 3, 13%) were identified. Patients reported a lack of empathy (n = 3, 13%), lack of cultural competence (n = 3, 13%), and inadequate communication (n = 2, 8%) from physicians. Qualitative analysis identified five major themes regarding the decision to undergo surgery: communication, trust, health literacy, patient fears, and decision-making strategies. Five patients (21%) declined the recommended surgery and were more likely Black (100% vs. 21%), lower income (100% vs. 16%), and reported poor patient-physician relationship (40% vs. 5%; all p < 0.05). CONCLUSIONS: Factors associated with declining recommended cancer surgery were underrepresented minority race and poor patient-physician relationships. Interventions are needed to improve these barriers to care and racial disparities.

RESUMEN

INTRODUCTION: Residency interviews have traditionally been conducted in person; however, COVID-19 forced programs to shift to virtual interviewing. This study delineated the nationwide trends observed after virtual interviewing across multiple application cycles on both surgical residency applicant competitiveness and program workload. METHODS: Publicly available National Residency Matching Program applicant and program data were retrospectively reviewed. Applicant competitiveness was assessed using a validated competitive index (# positions ranked/match rate). Interview types included in-person (2010-2020) or virtual (2021-2023), and programs were classified as general surgery (GS), surgical subspecialty (SS) - orthopedics, otolaryngology and neurosurgery, and integrated specialty (IS) - plastic, thoracic, and vascular surgery. RESULTS: When comparing in-person to virtual cohorts, the competitive index has increased in GS (0.97 ± 0.00 to 1.05 ± 0.01, P < 0.001), SS (0.97 ± 0.02 to 1.06 ± 0.01 P < 0.001), and IS (0.93 ± 0.06 to 1.12 ± 0.03, P = 0.001). United Sates Medical Licensing Examination Step scores and research experiences increased over time in GS and SS (P < 0.05). Program workload, represented by number of applications received per program increased in GS, IS, and SS (P < 0.05), as well as the number of interviews conducted in GS and SS (P < 0.05). Importantly, match rate remained stable in GS and IS, with a decrease in SS (0.69 ± 0.03 to 0.63 ± 0.02, P = 0.04). CONCLUSIONS: The residency application process has been irrevocably changed due to COVID-19. The rise in applicant volume and competitiveness places unique strains on applicants and programs. Additional modifications such as signaling and ACGME guidance are needed to help alleviate strain and ensure that residents and programs alike find their best fit.

RESUMEN

INTRODUCTION: Robotic-assisted minimally invasive esophagectomy (RAMIE) in clinical trials has demonstrated improved outcomes compared to open esophagectomy (OE). However, outcomes after national implementation remain unknown. The aim of this study was to evaluate postoperative outcomes after RAMIE. METHODS: Patients who underwent elective esophagectomy between 2016 and 2020 were identified from the American College of Surgeons-- National Surgical Quality Improvement Program esophageal targeted participant user files and categorized by operative approach, with patients who underwent hybrid procedures excluded. Outcomes were compared between OE and minimally invasive esophagectomy (MIE)/RAMIE, with subset analyses by minimally invasive operative approach. Primary outcomes included pulmonary complications, anastomotic leak requiring reintervention, all-cause morbidity, and 30-d mortality. RESULTS: In total 2786 patients were included, of which 58.3% underwent OE, 33.2% underwent MIE, and 8.4% underwent RAMIE. In the entire cohort, Ivor Lewis esophagectomy was the most common technique (64.6%), followed by transhiatal (22.0%), and a McKeown technique (13.4%). Comparing OE and MIE/RAMIE, pulmonary complications (21.5% versus 16.1%, P < 0.01) and all-cause morbidity (40.9% versus 32.3%, P < 0.01) were both reduced in the MIE/RAMIE group. When directly comparing MIE to RAMIE, there was no difference in the rate of pulmonary complications, anastomotic leak, all-cause morbidity, and mortality. However, RAMIE was associated with decreased all-cause morbidity compared to OE (40.9% versus 33.3%, P = 0.03). CONCLUSIONS: RAMIE was associated with decreased morbidity compared to OE, with similar outcomes to MIE. The national adoption of RAMIE in this select cohort appears safe.

RESUMEN

INTRODUCTION: The COVID-19 pandemic forced a sudden change from in-person to virtual interviews for the general surgery residency match. General surgery programs and applicants adopted multiple strategies to best mimic in-person recruitment. The purpose of this study was to evaluate applicant opinions of the virtual recruitment format. MATERIALS AND METHODS: Postinterview survey responses for applicants interviewing at a single general surgery residency program in the 2020-2021 and 2021-2022 cycles were evaluated. All interviewed applicants were sent an anonymous survey assessing the virtual interview structure, their impression of the program, and their opinions on recruitment in the future. RESULTS: The response rate was 31.2% (n = 60). Most (88.4%) respondents reported a more favorable view of the program after a virtual interview. Factors that were most likely to create a favorable impression were residents (89.6%) and culture (81.0%). 50.8% of applicants favored virtual-only interviews. The majority of applicants (60.3%), however, preferred the virtual interview remain a component of the application process, 34.4% recommended that virtual interviews be used as an initial screen before in-person invites, while 19.0% suggested applicants should interview in-person or virtually without penalty. 62.1% favored capping the number of interviews offered by programs and accepted by applicants. CONCLUSIONS: The virtual interview format for general surgery residency allows applicants to effectively evaluate a residency program. Applicants are in favor of a combination of virtual and in-person interviews in the future. Innovation in the recruitment process, including limiting the number of applications and incorporating virtual events, is supported by applicants.

RESUMEN

BACKGROUND: Despite the rising incidence of lung cancer in patients who never smoked, environmental risk factors such as ambient air pollution in this group are poorly described. Our objective was to identify the relationship of environmental exposures with lung cancer in patients who never smoked. METHODS: A prospectively collected database was reviewed for all patients with non-small cell lung carcinoma (NSCLC) who underwent resection from 2006 to 2021. Environmental exposures were estimated using the geocoded home address of patients. Logistic regression was used to determine the association of clinical and environmental variables with smoking status. Kaplan-Meier and Cox proportional hazards analyses were used to assess survival. RESULTS: A total of 665 patients underwent resection for NSCLC, of which 67 (10.1%) were patients who never smoked and 598 (89.9%) were current/former smokers. Patients who never smoked were more likely of white race (p = 0.001) and had well-differentiated tumors with carcinoid or adenocarcinoma histology (p < 0.001). Environmental exposures were similar between groups, but patients who never smoked had less community material deprivation (p = 0.002) measured by household income, education, health insurance, and vacancies. They had improved overall survival (p = 0.012) but equivalent cancer recurrence (p = 0.818) as those who smoked. In univariable Cox analyses, fine particulate matter (HR: 1.447 [95% CI 1.197-1.750], p < 0.001), distance to nearest major roadway (HR: 1.067 [1.024-1.111], p = 0.002), and greenspace (HR: 0.253 [0.087-0.737], p = 0.012) were associated with overall survival in patients who never smoked. CONCLUSIONS: Lung cancer patients who never smoked have unique clinical and pathologic characteristics, including higher socioeconomic status. Interventions to reduce environmental exposures may improve lung cancer survival in this population.

RESUMEN

BACKGROUND: Feeding jejunostomy (JT) tubes are often utilized as an adjunct to optimize nutrition for successful esophagectomy; however, their utility has come into question. The aim of this study was to evaluate utilization and outcomes associated with JTs in a nationwide cohort of patients undergoing esophagectomy. METHODS: The NSQIP database was queried for patients who underwent elective esophagectomy. JT utilization was assessed between 2010 and 2019. Post-operative outcomes were compared between those with and without a JT on patients with esophagectomy-specific outcomes (2016-2019), with results validated using a propensity score-matched (PSM) analysis based on key clinicopathologic factors, including tumor stage. RESULTS: Of the 10,117 patients who underwent elective esophagectomy over the past decade, 53.0% had a JT placed concurrently and 47.0% did not. Utilization of JTs decreased over time, accounting for 60.0% of cases in 2010 compared to 41.7% in 2019 (m = - 2.14 95%CI: [- 1.49]-[- 2.80], p < 0.01). Patients who underwent JT had more composite wound complications (17.0% vs. 14.1%, p = 0.02) and a higher rate of all-cause morbidity (40.4% vs. 35.5%, p = 0.01). Following PSM, 1007 pairs were identified. Analysis of perioperative outcomes demonstrated a higher rate of superficial skin infections (6.1% vs. 3.5%, p = 0.01) in the JT group. However, length of stay, reoperation, readmission, anastomotic leak, composite wound complications, all-cause morbidity, and mortality rates were similar between groups. CONCLUSIONS: Among patients undergoing elective esophagectomy, feeding jejunostomy tubes were utilized less frequently over the past decade. Similar perioperative outcomes among matched patients support the safety of esophagectomy without an adjunct feeding jejunostomy tube.

RESUMEN

BACKGROUND: Donation after circulatory death (DCD) liver transplantation (LT) has become an effective mechanism for expanding the donor pool and decreasing waitlist mortality. However, it is unclear if low-volume DCD centers can achieve comparable outcomes to high-volume centers. METHODS: From 2011 to 2019 utilizing the United Network for Organ Sharing (UNOS) database, liver transplant centers were categorized into tertiles based on their annual volume of DCD LTs. Donor selection, recipient selection, and survival outcomes were compared between very-low volume (VLV, n = 1-2 DCD LTs per year), low-volume (LV, n = 3-5), and high-volume (HV, n > 5) centers. RESULTS: One hundred and ten centers performed 3273 DCD LTs. VLV-centers performed 339 (10.4%), LV-centers performed 627 (19.2%), and HV-centers performed 2307 (70.4%) LTs. 30-day, 90-day, and 1-year patient and graft survival were significantly increased at HV-centers (all P < .05). Recipients at HV-centers had shorter waitlist durations (P < .01) and shorter hospital lengths of stay (P < .01). On multivariable regression, undergoing DCD LT at a VLV-center or LV-center was associated with increased 1-year patient mortality (VLV-OR:1.73, 1.12-2.69) (LV-OR: 1.42, 1.01-2.00) and 1-year graft failure (VLV-OR: 1.79, 1.24-2.58) (LV-OR: 1.28, .95-1.72). DISCUSSION: Increased annual DCD liver transplant volume is associated with improved patient and graft survival.

RESUMEN

BACKGROUND: The national opioid epidemic is a public health crisis. Thoracic surgery has also been associated with high incidence of new persistent opioid use. Our purpose was to describe the incidence and predictors of opioid use after lung cancer resection. METHODS: Retrospective review of lung cancer resections from 2015 to 2018 was performed using the Ohio Automated Rx Reporting System. Opioid dosing was recorded as milligram morphine equivalents (MME). Patients were stratified by preoperative opioid use. Chronic preoperative opioid users (opioid dependent) filled > 120 days supply of opioid pain medication in the 12 months prior to surgery; intermittent opioid users filled < 120 days. Chronic postoperative opioid users continued monthly use after 180 days postoperatively. RESULTS: 137 patients underwent resection. 16.1% (n = 22) were opioid dependent preoperatively, 29.2% (n = 40) were intermittent opioid users, and 54.7% (n = 75) were opioid naïve. Opioid dependent patients had higher daily inpatient opioid use compared to intermittent users and opioid naïve (43[30.0-118.1] MME vs 17.9[3.5-48.8] MME vs 8.8[2.1-25.0] MME, p < 0.001). Twenty-six percent (n = 35) of all patients were opioid users beyond 180 days postoperatively. Variables associated with opioid use > 180 days were: chronic preoperative opioid use (OR 23.8, p < 0.01), daily inpatient opioid requirement (1.02, p < 0.01), and neoadjuvant chemotherapy (28.2, p < 0.01). CONCLUSIONS: A quarter of patients are opioid dependent after lung cancer resection. This is due to both preexisting and new persistent opioid use. Improved strategies are needed to prevent chronic pain and opioid dependence after lung cancer resection.

RESUMEN

BACKGROUND: Rates of venous thromboembolism are increased in thoracic malignancy; however, coagulation patterns are not established. We hypothesize that patients with esophageal and lung malignancy have similar hypercoagulable pre- and postoperative profiles as defined by rotational thromboelastometry (ROTEM). METHODS: Prospective study was conducted in 47 patients with esophageal and lung cancer undergoing surgical resection. ROTEM evaluated pre/postoperative coagulation status. RESULTS: Patients with thoracic malignancy were hypercoagulable by ROTEM, but not by conventional coagulation tests. Preoperative hypercoagulability was higher in lung versus esophageal cancer (64 vs. 16%, p = 0.001). Lung cancer patients that were hypercoagulable preoperatively demonstrated decreased maximum clot firmness (MCF) (p = 0.044) and increased clot time (p = 0.049) after surgical resection, suggesting reversal of hypercoagulability. Resection of esophageal cancer increased hypercoagulability (16 vs. 56%, p = 0.002) via elevated MCF (reflecting platelet activity). Hypercoagulability remained at follow-up clinic for both lung and esophageal cancer patients. CONCLUSIONS: Hypercoagulability in patients with lung malignancies reversed following complete surgical resection, whereas hypercoagulability occurred only postoperatively in those with esophageal malignancies. In both, hypercoagulability was associated with fibrin and platelet function.

RESUMEN

OBJECTIVE: Aortobifemoral bypass has been the gold standard treatment for extensive aortoiliac occlusive disease. Endovascular therapy and stenting of aortic and iliac occlusive lesions has proven to be efficacious, especially when dealing with short segment lesions. Endovascular treatment of TransAtlantic Inter-Society Consensus II (TASC) D aortoiliac occlusive lesions remains a challenge, but a valuable treatment option in poor surgical candidates. We present our operative technique and midterm results in treating TASC D aortoiliac occlusive disease using unibody bifurcated endografts. METHODS: We performed a retrospective review of patients with TASC D aortoiliac occlusive disease who underwent transfemoral endovascular revascularization with the Endologix Powerlink unibody bifurcated endograft (Endologix, Irvine, Calif). Demographic data, operative details, and outcomes were collected. Paired t-tests were performed to compare preoperative and postoperative ankle brachial indexes. RESULTS: Between March 2009 and July 2011, 10 high-risk patients (8 male and 2 female) for a traditional aortobifemoral bypass were treated using this endovascular technique. The mean age was 59 ± 6 years (range, 50-69 years). All patients presented with rest pain, and four with tissue loss. Technical success was 100%, with two patients requiring brachial access and eight patients requiring additional stent placement. Postoperatively, all patients reported clinical improvement with resolution of ischemic symptoms. Mean improvement ankle brachial index was 0.50 ± 0.08 (P = .028) and 0.50 ± 0.01 (P = .034) in the left and right legs, respectively. Mean follow-up time was 40 ± 24 months (range, 4-81 months). The primary and secondary patency rates were 80% and 100%, respectively. Complications requiring early reintervention occurred in two patients and included one expanding hematoma from the percutaneous access site and one acute iliac artery thrombosis. Additionally, one patient underwent repeat angioplasty/stenting for threatened endograft limbs at 4 months. One patient expired during follow-up from an unrelated cardiac cause 19 weeks postoperatively. CONCLUSIONS: This series demonstrates that endovascular repair using a unibody bifurcated endograft for TASC D aortoiliac occlusive disease is feasible, effective, and has excellent midterm patency. It should be considered an effective treatment option when the disease process involves the aorta, in particular if the patient is surgically unfit for a traditional aortobifemoral bypass. The unibody configuration preserves the anatomic aortic bifurcation, which is particularly important in patients with peripheral occlusive disease who are deemed to undergo subsequent endovascular interventions.

RESUMEN

To our knowledge, this is the first comprehensive review on the subject of venous thromboembolism (VTE) and hypercoagulability in burn patients. Specific changes in coagulability are reviewed using data from thromboelastography and other techniques. Disseminated intravascular coagulation in burn patients is discussed. The incidence and risk factors associated with VTE in burn patients are then examined, followed by the use of low-molecular-weight heparin thromboprophylaxis and monitoring techniques using antifactor Xa levels. The need for large, prospective trials in burn patients is highlighted, especially in the areas of VTE incidence and safe, effective thromboprophylaxis.

RESUMEN

BACKGROUND: Adrenal masses are common incidental findings on radiologic imaging. The association between malignancy and hormonal hyperactivity found in incidentally discovered adrenal tumors, however, remains unclear. METHODS: A retrospective analysis of prospectively collected data from patients who underwent adrenalectomy for incidentally discovered adrenal tumors at a single institution. Outcomes and operative data were compared by univariate analysis. Area under the curve was used to analyze the effect of tumor size in predicting malignancy. RESULTS: There were 49 patients who initially presented with adrenal incidentalomas that underwent adrenalectomy. Most patients were Caucasian women with an average age of 51 ± 14 years. Of this group, 24 patients underwent resection for hyperfunctioning adrenal glands. There were no significant differences in malignancy rates between hyperfunctional and nonfunctional tumors (4.1% vs. 12.0%, P = 0.32). On final histopathology, there were four patients with adrenal malignancies: two adrenocortical carcinomas and two metastatic from renal carcinoma. Only one patient with a hyperfunctioning adrenal tumor had underlying malignancy. Overall, invasion of adjacent structures (P < 0.001), presence of lymphadenopathy (P = 0.02), metastasis (P = 0.03), irregular tumor margins (P = 0.01), heterogeneity (P = 0.05), and tumor size >6 cm (P = 0.04) on radiologic imaging were strongly associated with malignancy in adrenal incidentalomas. CONCLUSIONS: The risk of concomitant malignancy and hormonal hyperactivity in adrenal incidentalomas is very low. Tumor size (>6 cm) and radiographic features remain the most important predictors of adrenal malignancy, regardless of tumor function.

RESUMEN

BACKGROUND: Extremity wounds account for most battlefield injuries. Clinical examination may be unreliable by medics or first responders, and continuous assessment by experienced practitioners may not be possible on the frontline or during transport. Near-infrared spectroscopy (NIRS) provides continuous, noninvasive monitoring of tissue oxygen saturation (StO2), but its use is limited by inter-patient and intra-patient variability. We tested the hypothesis that bilateral NIRS partially addresses the variability problem and can reliably identify vascular injury after extremity trauma. MATERIALS AND METHODS: This prospective study consisted of 30 subjects: 20 trauma patients with extremity injury and 10 healthy volunteers. Bilateral StO2 tissue sensors were placed on the thenar eminence or medial plantar surface. Injured and non-injured extremities within the same patient (ΔStO2) were compared using Wilcoxon signed ranks test. Receiver operating characteristic curves were generated and areas under the curve (AUCs) were calculated for ΔStO2 of 6, 10, and 15. Values are expressed as median (interquartile range). RESULTS: Trauma patients were age 31 y (23 y), 85% male, with injury severity score of 9 (5). There were seven arterial and three venous injuries. Most involved the lower extremity (n = 16; 80%) and resulted from a penetrating mechanism (n = 14; 70%). ΔStO2 between limbs was 20.4 (10.4) versus 2.4 (3.0) (P < 0.001) for all patients with vascular injury versus patients and volunteers with no vascular injury. ΔStO2 reliably identified any vascular injury (AUC, 0.975; P < 0.001), whereas pulse examination alone or in combination with Doppler exam could detect only arterial injury. A ΔStO2 of 6 had the greatest sensitivity and specificity (AUC, 0.900; P < 0.001). CONCLUSIONS: Continuous monitoring of bilateral limbs with NIRS detects changes in perfusion resulting from arterial or venous injury and may offer advantages over serial manual measurements of pulses or Doppler signals. This technique may be most relevant in military and disaster scenarios or during transport, in which the ability to monitor limb perfusion is difficult or experienced clinical judgment is unavailable.

RESUMEN

BACKGROUND: Tumors of the thymus are very rare in the pediatric population. This study examines the current trends and outcomes of children with thymus tumors. METHODS: The Surveillance, Epidemiology and End Results (SEER) registry was queried for all patients <20 y of age with primary thymic malignancies from 1973 to 2008. RESULTS: A total of 73 pediatric patients were identified with malignant thymic tumors. The median age at diagnosis was 13 y old. Among the 20 patients that presented with distant disease, 70% died. Conversely, among the 23 patients that presented with locoregional disease, 70% survived. Although the overall mean survival time was 89 ± 116 mo, 45% of patients died over the study period. Patients with Hodgkin lymphomas and germ cell tumors exhibited the highest survival (76% and 60% at 10 y, respectively). Multivariate analysis was used to identify local or regional tumor stage (odds ratio = 4.5, 95% confidence interval = 1.4-14.5) and surgical resection (OR = 3.8, 95% confidence interval = 1.4-10.8) as independent predictors of survival. CONCLUSIONS: Malignant thymomas and lymphomas are the most common histological variants of pediatric thymus tumors, and patients with Hodgkin lymphomas exhibit the highest survival. Surgery is more commonly performed on malignant thymomas and is an independent prognostic indicator of survival.

RESUMEN

OBJECTIVE: Lung cancer screening can decrease mortality. The majority of screen-detected cancers are early stage and undergo surgical resection. However, there are little data regarding the outcomes of surgical treatment outside of clinical trials. The purpose of this study was to compare the outcomes of curative resection for screen-detected lung cancers with nonscreened, incidentally detected cancers at an institution with a structured screening program. METHODS: Patients undergoing lung cancer curative resection from January 2012 to June 2021 were identified from a prospective database. Baseline patient characteristics, tumor characteristics, and outcomes were compared between cancer detected from screening and cancer detected incidentally. RESULTS: There were 199 patients in the incidental group and 82 patients in the screened group. Mean follow-up was 33.3 ± 25 months. The screened group had more African Americans (P = .04), a higher incidence of emphysema (P = .02), less prior cancers (P < .01), and more pack-years smoked (P < .01). The screened group had a smaller size (1.74 vs 2.31 cm, P < .01); however, pathologic stage was similar, with the majority being stage I. Postoperative morbidity, 30-day mortality, and overall and recurrence-free survival were similar between groups. Only 48.7% of the incidental group met current US Preventative Services Task Force screening criteria (age 50-80 years, ≥20 pack-year smoking history). CONCLUSIONS: Screen-detected lung cancers have excellent postoperative and long-term outcomes with curative resection, similar to incidentally detected cancers. A large portion of incidentally detected lung cancers do not meet current screening guidelines, which is an opportunity for further refinement of eligibility.

RESUMEN

BACKGROUND: Enhanced recovery after surgery (ERAS) has been associated with improved perioperative outcomes after thoracic surgery; however, the impact on long-term opioid use remains unknown. The aim of our study was to evaluate the effects of ERAS on long-term opioid use. METHODS: Patients who underwent pulmonary resection were identified from a prospectively maintained database and linked to the regional prescription drug monitoring program. Outcomes were compared between pre-ERAS (February 2016 to November 2018) and ERAS (December 2018 to June 2020) cohorts. Our ERAS protocol included regional anesthetic, multimodal pain control, and protocolized rehabilitation. RESULTS: We analyzed 240 pulmonary resections, 64.6% (n = 155) in the pre-ERAS era and 35.4% (n = 85) in the ERAS era. Baseline characteristics were similar; however, more patients in the ERAS cohort underwent minimally invasive surgery (67.7% vs 87.9%; P = .002). Median length of stay was reduced (5 days vs 4 days; P = .03) upon implementation of ERAS, with no change in perioperative complications or readmission rate. On multivariate analysis, ERAS was associated with decreased total inpatient morphine milligram equivalent and discharge morphine milligram equivalent. However, both long-term opioid use up to 1 year postoperatively and new persistent opioid use remained similar despite implementation of ERAS. On multivariate analysis, implementation of ERAS was not associated with a reduction in opioid use 14 to 90 days postoperatively or persistent opioid use 90 to 180 days postoperatively. CONCLUSIONS: Despite short-term opioid reduction, long-term opioid use persisted after implementation of ERAS. Additional strategies to monitor for and avoid opioid dependence are urgently needed to prevent chronic opioid use after pulmonary resection.
