University Hospital Financial Status Does Not Influence Subjective Perception of General Surgery Residents on Training Adequacy.

BACKGROUND: Surgical residency training is a complex and costly task. Hospital economic health is dependent on different variables, but it is especially linked to the country macroeconomics that may be extremely fluctuating, especially in underdeveloped countries. This study analyzed the correlation between a single-center university hospital financial status and subjective perception of general surgery residents on program support and adequacy. METHODS: We surveyed former residents that started general surgery residency program in a tertiary university hospital between 1999 and 2017. Individuals answered a questionnaire about the perception of the influence of the hospital´s financial status on training. Hospital´s financial status was estimated yearly by the current liquidity ratio (CLR) that measures whether or not a company has enough resources to meet its short-term obligations. RESULTS: Two hundred and fifty-seven (96%) were still in surgical practice; 242 (93%) were satisfied with their residency training; 210 (78%) believed training was affected by financial status; 183 (68%) believed they were prepared for independent practice; 180 (67%) practiced in an academic environment; 146 (54%) felt the need to complete specialty training beyond residency; and 56 (21%) believed hospital financial status was adequate. The rate of positive or negative answers did not correlate with the current liquidity ratio, except for the need to complete specialty training that was indirectly related to CLR. CONCLUSIONS: University hospital financial status did not influence subjective perception of general surgery residents on training, program support and adequacy.

A Novel University of North Carolina Laparoscopic Ventral Hernia Repair Simulator.

Background: Simulation plays an important role in surgical training. We developed a simulator for laparoscopic ventral hernia repair (LVHR) surgery based on porcine tissue, characterized by low cost and high reality. Methods: Our LVHR model is based on porcine tissue mounted in a human mannequin. The anterior abdominal wall is constructed to allow laparoscopic training. Training sessions are conducted in a simulated operating room environment. Results: During preliminary tests, the LVHR simulator was found to be highly realistic in terms of tissue feedback, instrumentation usage, and performing the key steps of the LVHR procedure. The model was evaluated as a very useful tool for residents' training allowing to gain laparoscopic skills, learn the key steps of LVHR, and practice team work. Conclusions: Our simulator, based on porcine tissue mounted in a mannequin, offers a very realistic and cost-effective model for simulating LVHR surgery.

Disparities in esophageal cancer: less treatment, less surgical resection, and poorer survival in disadvantaged patients.

The incidence of esophageal cancer has increased steadily in the last decades in the United States. The aim of this paper was to characterize disparities in esophageal cancer treatment in different racial and socioeconomic population groups and compare long-term survival among different treatment modalities. A retrospective analysis of the National Cancer Database was performed including adult patients (≥18 years old) with a diagnosis of resectable (stages I-III) esophageal cancer between 2004 and 2015. Multivariable logistic regression models were used to determine the odds of being offered no treatment at all and surgical treatment across race, primary insurance, travel distance, income, and education levels. Multivariable Cox proportional hazards models were used to compare 5-year survival rates across different treatment modalities. A total of 60,621 esophageal cancer patients were included. Black patients, uninsured patients, and patients living in areas with lower levels of education were more likely to be offered no treatment. Similarly, black race, female patients, nonprivately insured patients, and those living in areas with lower median residential income and lower education levels were associated with lower rates of surgery. Patients receiving surgical treatment, compared to both no treatment and definitive chemoradiation, had significant better long-term survival in stage I, II, and III esophageal cancer. In conclusion, underserved patients with esophageal cancer appear to have limited access to surgical care, and are, in fact, more likely to not be offered any treatment at all. Considering the survival benefits associated with surgical resection, greater public health efforts to reduce disparities in esophageal cancer are needed.

Racial and Socioeconomic Disparities in the Surgical Management and Outcomes of Patients with Colorectal Carcinoma.

INTRODUCTION: Colorectal cancer (CRC) is the second leading cause of cancer mortality in the USA. We aimed to determine racial and socioeconomic disparities in the surgical management and outcomes of patients with CRC in a contemporary, national cohort. METHODS: We performed a retrospective analysis of the National Inpatient Sample for the period 2009-2015. Adult patients diagnosed with CRC and who underwent colorectal resection were included. Multivariable linear and logistic regressions were used to assess the effect of race, insurance type, and household income on patient outcomes. RESULTS: A total of 100,515 patients were included: 72,552 (72%) had elective admissions and 27,963 (28%) underwent laparoscopic surgery. Patients with private insurance and higher household income were consistently more likely to have laparoscopic procedures, compared to other insurance types and income levels, p < 0.0001. Black patients, compared to white patients, were more likely to have postoperative complications (OR 1.23, 95% CI, 1.17, 1.29). Patients with Medicare and Medicaid, compared to private insurance, were also more likely to have postoperative complications (OR 1.30, 95% CI, 1.24, 1.37 and OR 1.40, 95% CI, 1.31, 1.50). Patients in low-household-income areas had higher rates of any complication (OR 1.11, 95% CI 1.06, 1.16). CONCLUSIONS: The use of laparoscopic surgery in patients with CRC is strongly influenced by insurance type and household income, with Medicare, Medicaid and low-income patients being less likely to undergo laparoscopic surgery. In addition, black patients, patients with public insurance, and patients with low household income have significant worse surgical outcomes.

Cognitive Assessment of Surgeons During Surgical Procedures: Influence of Time and Intraoperative Complications.

INTRODUCTION: Surgeon's performance may be influenced by several factors that may affect skills and judgement, which ultimately represents surgeon´s cognition. Cognition refers to all forms of knowing and awareness, such as perceiving, conceiving, remembering, reasoning, judging, imagining, and problem solving. This report aims to evaluate the effect of operative time and operative complications on surgeon´s cognition. METHODS: Forty-six surgeons (mean age 31 years, 78% males) assigned to an operation expected to last for at least 2 h, volunteered for the study. All participants underwent 3 cognitive tests at the beginning of the operation and hourly, until the end of the procedure: (a) concentration (serial sevens, counting down from 100 by sevens); (b) visual (fast counting, counting the number of circles with the same color among a series of circles); and (c) motor (trail making, connecting a set of numbered dots). Intraoperative complications were recorded. RESULTS: The visual test had a stable behavior along time. Concentration and motor tests tend to be performed faster. Intraoperative complications occurred in 5 (11%) cases (3 hemorrhage and 2 organ injuries). Performance time was stable for concentration and motor tests but visual test tends to be performed faster in cases with an intraoperative complication. CONCLUSION: Our results showed that (1) time does not jeopardize surgeons' cognition, but rather surgeons learned to perform the tests faster, and (2) complications do not decrease surgeons' cognition.

Postoperative outcomes of esophagectomy for cancer in elderly patients.

BACKGROUND: The number of elderly patients with esophageal cancer is expected to increase. We aimed to determine the postoperative outcomes of esophagectomy for esophageal cancer in elderly patients. MATERIAL AND METHODS: A retrospective, population-based analysis was performed using the National inpatient sample for the period 2000-2014. Adult patients ≥18 years old (yo) diagnosed with esophageal cancer who underwent esophagectomy during their inpatient hospitalization were included. Patients were categorized into <70 yo and ≥70 yo. Multivariable linear and logistic regressions were used to assess the potential effect of age on postoperative complications, inpatient mortality, and hospital charges. RESULTS: Overall, 5243 patients were included, with 3699 (70.6%) <70 yo and 1544 (29.5%) ≥70 yo. The yearly rate of esophagectomies among patients ≥70 yo did not significantly changed during the study period (28.4% in 2000 and 26.3% in 2014, P = 0.76). Elderly patients were significantly more likely to have postoperative cardiac failure (odds ratio 1.59, 95% confidence interval [CI] 1.21, 2.09, P = 0.0009) and inpatient mortality (odds ratio 1.84, 95% CI 1.39, 2.45, P < 0.0001). Among the elderly patients, hospital charges were, on average, $16,320 greater (95% CI $3110, $29,530) than patients <70 yo (P = 0.02). The predicted probability of mortality increased consistently across age (1.5% in 40 yo, 2.5% in 50 yo, 3.6% in 60 yo, 5.4% in 70 yo, and 7.0% in 80 yo). CONCLUSIONS: Elderly patients undergoing esophagectomy for cancer have a significantly higher risk of postoperative mortality and pose a higher financial burden on the health care system. Elderly patients with esophageal cancer should be carefully selected for surgery.

Esophageal Cancer Surgery: Spontaneous Centralization in the US Contributed to Reduce Mortality Without Causing Health Disparities.

BACKGROUND: Improvement in mortality has been shown for esophagectomies performed at high-volume centers. OBJECTIVE: This study aimed to determine if centralization of esophageal cancer surgery occurred in the US, and to establish its impact on postoperative mortality. In addition, we aimed to analyze the relationship between regionalization of cancer care and health disparities. METHODS: A retrospective population-based analysis was performed using the National Inpatient Sample for the period 2000-2014. Adult patients (≥ 18 years of age) diagnosed with esophageal cancer and who underwent esophagectomy were included. Yearly hospital volume was categorized as low (< 5 procedures), intermediate (5-20 procedures), and high (> 20 procedures). Multivariable analyses on the potential effect of hospital volume on patient outcomes were performed, and the yearly rate of esophagectomies was estimated using Poisson regression. RESULTS: A total of 5235 patients were included. Esophagectomy at low- [odds ratio (OR) 2.17] and intermediate-volume (OR 1.62) hospitals, compared with high-volume hospitals, was associated with a significant increase in mortality. The percentage of esophagectomies performed at high-volume centers significantly increased during the study period (29.2-68.5%; p < 0.0001). The trend towards high-volume hospitals was different among the different US regions: South (7.7-54.3%), West (15.0-67.6%), Midwest (37.3-67.7%), and Northeast (55.8-86.8%) [p < 0.0001]. Overall, the mortality rate of esophagectomy dropped from 10.0 to 3.5% (p = 0.006), with non-White race, public insurance, and low household income patients also showing a significant reduction in mortality. CONCLUSIONS: A spontaneous centralization for esophageal cancer surgery occurred in the US. This process was associated with a decrease in the mortality rate, without contributing to health disparities.

Antireflux Surgery in the USA: Influence of Surgical Volume on Perioperative Outcomes and Costs-Time for Centralization?

BACKGROUND: Few studies have analyzed the relationship between surgical volume and outcomes after antireflux procedures. The aim of this study was to determine the effect of surgical volume on postoperative results and costs for patients undergoing surgery for gastroesophageal reflux disease. METHODS: We analyzed the National Inpatient Sample (period 2000-2013). Adult patients (≥18 years old) with gastroesophageal reflux disease who underwent fundoplication were included. Hospital surgical volume was determined using the 30th and 60th percentile cut points using weighted discharges and categorized as low (<10 operations/year), intermediate (10-25 operations/year), or high (>25 operations/year). We performed multivariable logistic regression models to assess the effect of surgical volume on patient outcomes. RESULTS: The studied cohort comprised 75,544 patients who had antireflux surgery. When operations performed at low-volume hospitals, postoperative bleeding, cardiac failure, renal failure, respiratory failure, and inpatient mortality were more common. In intermediate-volume hospitals, patients were more likely to have postoperative infection, esophageal perforation, bleeding, cardiac failure, renal failure, and respiratory failure. The length of hospital stay was longer at low- and intermediate-volume hospitals (1.08 and 0.55 days longer, respectively). There was an increase in charges of 5120 dollars per patient at low-volume centers, and 4010 dollars per patient at intermediate-volume centers. CONCLUSIONS: When antireflux surgery is performed at high-volume hospitals, morbidity is lower, length of hospital stay is shorter, and costs for the healthcare system are decreased.

Comparative Analysis of Perioperative Outcomes and Costs Between Laparoscopic and Open Antireflux Surgery.

BACKGROUND: Laparoscopic antireflux surgery (LARS) has proven to be as effective as open antireflux surgery (OARS), but it is associated with a shorter hospital stay and a faster recover. The aims of this study were to assess the national use of LARS in the US and to compare the perioperative outcomes between laparoscopic and open antireflux procedures in a national cohort. STUDY DESIGN: A retrospective population-based analysis was performed using the National Inpatient Sample for the period 2000 to 2013. The study included adult patients (18 years and older) diagnosed with gastroesophageal reflux disease (GERD), who underwent either laparoscopic or open fundoplication. Multivariable linear and logistic regression, adjusted for patient demographics, comorbidities, and hospital characteristics were used to assess the effect of the laparoscopic approach on patient outcomes. RESULTS: A total of 75,544 patients were included, with 44,089 having LARS (58.4%) and 31,455 having OARS (41.6%). The rate of laparoscopic procedures increased from 24.8 LARS per 100 procedures in 2000, to 84.3 LARS per 100 procedures in 2013 (p < 0.0001). Patients undergoing laparoscopic surgery were less likely to experience postoperative venous thromboembolism, wound complications, infection, esophageal perforation, bleeding, cardiac failure, renal failure, respiratory failure, shock, and inpatient mortality. On average, the laparoscopic approach reduced length of stay by 2.1 days, and decreased hospital charges by $9,530. CONCLUSIONS: The use of the laparoscopic approach for the surgical treatment of GERD has increased significantly in the last decade in the US. This approach is associated with lower morbidity and mortality, shorter hospital stay, and lower costs for the health care system.

Characterization of Mentorship Programs in Departments of Surgery in the United States.

Importance: Mentorship is considered a key element for career satisfaction and retention in academic surgery. Stakeholders of an effective mentorship program should include the mentor, the mentee, the department, and the institution. Objective: The objective of this study was to characterize the status of mentorship programs in departments of surgery in the United States, including the roles of all 4 key stakeholders, because to our knowledge, this has never been done. Design, Setting, and Participants: A survey was sent to 155 chairs of departments of surgery in the United States in July 2014 regarding the presence and structure of the mentorship program in their department. The analysis of the data was performed in November 2014 and December 2014. Main Outcomes and Measures: Presence and structure of a mentorship program and involvement of the 4 key stakeholders. Results: Seventy-six of 155 chairs responded to the survey, resulting in a 49% response rate. Forty-one of 76 of department chairs (54%) self-reported having an established mentorship program. Twenty-five of 76 departments (33%) described no formal or informal pairing of mentors with mentees. In 62 (82%) and 59 (78%) departments, no formal training existed for mentors or mentees, respectively. In 42 departments (55%), there was no formal requirement for the frequency of scheduled meetings between the mentor and mentee. In most departments, mentors and mentees were not required to fill out evaluation forms, but when they did, 28 of 31 were reviewed by the chair (90%). In 70 departments (92%), no exit strategy existed for failed mentor-mentee relationships. In more than two-thirds of departments, faculty mentoring efforts were not recognized formally by either the department or the institution, and only 2 departments (3%) received economic support for the mentoring program from the institution. Conclusions and Relevance: These data show that only half of departments of surgery in the United States have established mentorship programs, and most are informal, unstructured, and do not involve all of the key stakeholders. Given the importance of mentorship to career satisfaction and retention, development of formal mentorship programs should be considered for all academic departments of surgery.

Emerging Techniques in Minimally Invasive Surgery. Pros and Cons.

New trends have emerged regarding the best minimally invasive access approaches to perform gastrointestinal surgery. However, these newer approaches are seen critically by those who demand a more strict assessment of outcomes and safety. An international panel of expert gathered at the 2014 American College of Surgeons Meeting with the goal of providing an evidence-based understanding of the real value of these approaches in gastrointestinal surgery. The panel has compared the efficacy and safety of most established approaches to gastrointestinal diseases to those of new treatment modalities: peroral esophageal myotomy vs. laparoscopic myotomy for achalasia, transgastric vs. transvaginal approach, and single-incision vs. multi-port access minimally invasive surgery. The panel found that (1) the outcome of these new approaches was not superior to that of established surgical procedures; (2) the new approaches are generally performed in few highly specialized centers; and (3) transgastric and transvaginal approaches might be safe and feasible in very experienced hands, but cost, training, operative time, and tools seem to limit their application for the treatment of common procedures such as cholecystectomy and appendectomy. Because the expected advantages of new approaches have yet to be proven in controlled trials, new approaches should be considered for adoption into practice only after thorough analyses of their efficacy and effectiveness and appropriate training.
