Disruption Index in Otolaryngology: Uncovering a Bibliometric History of a Rapidly Evolving Field.

OBJECTIVES: As the volume of research publications in the field of otolaryngology has increased, so has the need to qualify articles through bibliometric analyses to identify the most important and impactful work in the field. Herein, we aim to identify the 100 most disruptive articles in ENT over a 60-year period and examine how disruption index (DI) compares with other bibliometrics in identifying impactful works in the field. METHODS: In this cross-sectional bibliometric analysis, articles published between 1954 and 2014 in commonly referenced otolaryngology-head and neck surgery (OHNS) journals were queried in PubMed. Publications were characterized by DI, journal, subspecialty discipline, and status as an impactful article in the field as determined by other bibliometrics such as citation count, the "Sleeping Beauty Index," and those derived by the modified Delphi process. RESULTS: Of the 122,094 articles queried, 67,561 (55.3%) had available citation count as well as disruption score data, meeting inclusion criteria. The most represented subspecialty disciplines within the top 100 most disruptive articles were Otology/Neurotology (28%), General (Comprehensive) (27%), Head and Neck Surgery (12%), and Laryngology (11%). Fifty percent of articles identified as Sleeping Beauties and impactful via modified Delphi approach had scores in the top 86th percentile. CONCLUSION: DI in otolaryngology can be appreciated as an added dimension to existing indices and can unearth seminal research, which serve as early foundations of evidence-based management in the field of OHNS today. LEVEL OF EVIDENCE: NA Laryngoscope, 134:629-636, 2024.

Practice Patterns for Organ Preservation in US Patients With Rectal Cancer, 2006-2020.

Importance: In March 2023, the National Comprehensive Cancer Network endorsed watch and wait for those with complete clinical response to total neoadjuvant therapy. Neoadjuvant therapy is highly efficacious, so this recommendation may have broad implications, but the current trends in organ preservation in the US are unknown. Objective: To describe organ preservation trends among patients with rectal cancer in the US from 2006 to 2020. Design, Setting, and Participants: This retrospective, observational case series included adults (aged ≥18 years) with rectal adenocarcinoma managed with curative intent from 2006 to 2020 in the National Cancer Database. Exposure: The year of treatment was the primary exposure. The type of therapy was chemotherapy, radiation, or surgery (proctectomy, transanal local excision, no tumor resection). The timing of therapy was classified as neoadjuvant or adjuvant. Main Outcomes and Measures: The primary outcome was the absolute annual proportion of organ preservation after radical treatment, defined as chemotherapy and/or radiation without tumor resection, proctectomy, or transanal local excision. A secondary analysis examined complete pathologic responses among eligible patients. Results: Of the 175 545 patients included, the mean (SD) age was 63 (13) years, 39.7% were female, 17.4% had clinical stage I disease, 24.7% had stage IIA to IIC disease, 32.1% had stage IIIA to IIIC disease, and 25.7% had unknown stage. The absolute annual proportion of organ preservation increased by 9.8 percentage points (from 18.4% in 2006 to 28.2% in 2020; P < .001). From 2006 to 2020, the absolute rate of organ preservation increased by 13.0 percentage points for patients with stage IIA to IIC disease (19.5% to 32.5%), 12.9 percentage points for patients with stage IIIA to IIC disease (16.2% to 29.1%), and 10.1 percentage points for unknown stages (16.5% to 26.6%; all P < .001). Conversely, patients with stage I disease experienced a 6.1-percentage point absolute decline in organ preservation (from 26.4% in 2006 to 20.3% in 2020; P < .001). The annual rate of transanal local excisions decreased for all stages. In the subgroup of 80 607 eligible patients, the proportion of complete pathologic responses increased from 6.5% in 2006 to 18.8% in 2020 (P < .001). Conclusions and Relevance: This case series shows that rectal cancer is increasingly being managed medically, especially among patients whose treatment historically relied on proctectomy. Given the National Comprehensive Cancer Network endorsement of watch and wait, the increasing trends in organ preservation, and the nearly 3-fold increase in complete pathologic responses, international professional societies should urgently develop multidisciplinary core outcome sets and care quality indicators to ensure high-quality rectal cancer research and care delivery accounting for organ preservation.

Ursodiol Prescriptions Following Bariatric Surgery: National Prescribing Trends and Outcomes.

BACKGROUND: Rapid weight loss after bariatric surgery is a risk factor for gallstone development. Numerous studies have shown that ursodiol after surgery decreases rates of gallstone formation and cholecystitis. Real-world prescribing practices are unknown. This study aimed to examine prescription patterns for ursodiol and reassess its impact on gallstone disease using a large administrative database. METHODS: The Mariner database (PearlDiver, Inc.) was queried using Current Procedural Terminology codes for Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) between 2011 and 2020. Only patients with International Classification of Disease codes for obesity were included. Patients with pre-operative gallstone disease were excluded. The primary outcome was gallstone disease within 1 year, which was compared between patients who did and did not receive an ursodiol prescription. Prescription patterns were also analyzed. RESULTS: Three hundred sixty-five thousand five hundred patients fulfilled inclusion criteria. Twenty-eight thousand seventy-five (7.7%) patients were prescribed ursodiol. There was a statistically significant difference in development of gallstones (p < 0.001), development of cholecystitis (p = .049), and undergoing cholecystectomy (p < 0.001). There was a statistically significant decrease in the adjusted odds ratio (aOR) for the development of gallstones (aOR 0.81, 95% CI: 0.74, 0.89), development of cholecystitis (aOR 0.59, 95% CI: 0.36, 0.91), and undergoing cholecystectomy (aOR 0.75, 95% CI: 0.69, 0.81). CONCLUSION: Ursodiol significantly decreases the odds of development of gallstones, cholecystitis, or cholecystectomy within 1 year following bariatric surgery. These trends hold true when analyzing RYGB and SG separately. Despite the benefit of ursodiol, only 10% of patients received an ursodiol prescription postoperatively in 2020.

Safety and Efficacy of Extended Postdischarge Venous Thromboembolism Prophylaxis in Microsurgical Breast Reconstruction.

Discharging patients on extended postoperative venous thromboembolism (VTE) prophylaxis is trending in microsurgical breast reconstruction (MBR). This study investigated contemporary bleeding and thromboembolic complications after MBR and reported postdischarge enoxaparin outcomes. Methods: The PearlDiver database was queried for MBR patients who did not receive postdischarge VTE prophylaxis (cohort 1) and MBR patients discharged with enoxaparin for at least 14 days (cohort 2), then queried for hematoma, deep venous thrombosis (DVT), and/or pulmonary embolism. Concurrently, a systematic review was undertaken to identify studies investigating VTE with postoperative chemoprophylaxis. Results: In total, 13,541 patients in cohort 1 and 786 patients in cohort 2 were identified. The incidence of hematoma, DVT, and pulmonary embolism were 3.51%, 1.01%, 0.55% in cohort 1, and 3.31%, 2.93%, and 1.78% in cohort 2, respectively. There was no significant difference in hematoma between these two cohorts (P = 0.767); however, a significantly lower rate of DVT (P < 0.001) and pulmonary embolism (P < 0.001) occurred in cohort 1. Ten studies met systematic review inclusion. Only three studies reported significantly lower VTE rates with postoperative chemoprophylaxis. Seven studies found no difference in bleeding risk. Conclusions: This is the first study utilizing a national database and a systematic review to investigate extended postoperative enoxaparin in MBR. Overall, rates of DVT/PE seem to be declining compared with previous literature. The results of this study suggest that there remains a lack of evidence supporting extended postoperative chemoprophylaxis, although the therapy appears safe in that it does not increase bleeding risk.

Effect of Operative Time on Outcomes of Minimally Invasive Versus Open Pancreatoduodenectomy.

OBJECTIVE: To evaluate how operative time interacts with outcomes among different approaches to pancreaticoduodenectomy (PD). Minimally invasive PDs (MIPD), which include laparoscopic (LPD) and robotic (RPD) approaches, are increasingly performed in the USA. MIPD are generally associated with longer operative times (OT) compared to open PD (OPD). Increased OT is associated with inferior outcomes for OPD; however, the effect of OT on MIPD is not well understood. METHODS: National Surgical Quality Improvement Program (NSQIP)-targeted pancreatectomy dataset was utilized (2014-2019). Propensity score matching, logistic regression, and mixed effect modeling were performed to determine the effect of OT on outcomes following PD. OTs were stratified by quartiles for each approach, and outcomes were subsequently compared. RESULTS: Among 23,988 PDs, 22,185 were OPD and 1803 MIPD. Increased OT was associated with greater overall morbidity in all approaches. When comparing OT quartiles, MIPD was consistently associated with improved overall morbidity compared to OPD in matched cohorts. However, for upper quartiles, prolonged OT in MIPD was associated with significantly increased reoperation rates and mortality. The effect of OT on overall morbidity and other outcomes was comparable among LPD and RPD. CONCLUSIONS: In this study, increased OT was associated with incremental increases in overall morbidity after PD, irrespective of approach. While MIPD was associated with improved overall morbidity compared to OPD when stratified by OT quartile, higher mortality rates were observed with prolonged OT only with MIPD. Those data suggest that MIPD is a safe alternative to OPD when OT is optimized. NSQIP was used to compare the effect of operative time (OT) on outcomes following pancreaticoduodenectomy (PD), stratified by approach. Increased OT was associated with inferior outcomes following open, laparoscopic, and robotic PD. Surgeons should attempt to optimize OT, regardless of the approach to PD.

Mediating Factors Between Race and Time to Treatment in Colorectal Cancer.

BACKGROUND: Previous disparities research has demonstrated that underrepresented racial minority patients have worse colorectal cancer outcomes and that they experience unnecessary delays in time to treatment. These delays may explain worse colorectal cancer outcomes for minority patients and serve as a marker of inequalities in our healthcare system. OBJECTIVE: This study aims to quantify the mechanisms that contribute to this disparity in treatment delay. DESIGN: This is a retrospective analysis of colorectal cancer patients who underwent elective resection from 2004 to 2017. A causal inference mediation analysis using the counterfactual framework was utilized to estimate the extent to which racial disparities among patient factors explain the racial disparities in time to treatment. Mediators included income, education, comorbidities, insurance, and hospital type. SETTINGS: This study was conducted at hospitals participating in the National Cancer Database. PATIENTS: Stage I-III colorectal cancer patients, ≥18 years old, who underwent elective resection from 2004 through 2017 were included. MAIN OUTCOMES MEASURES: The primary measures were indirect effects of mediators between race and delayed time to treatment. RESULTS: Of the 504,405 patients (370,051 colon and 134,354 rectal), 10%, 5%, and 4% were black, Hispanic, and other. In multivariable models, compared to white patients, these patients had 25%, 27%, and 17% greater odds of delayed treatment. Mediation analyses suggested that 43%, 20%, and 31% of the treatment delay among them could be removed if an intervention equalized income, education, comorbidities, insurance, and hospital type to that of white patients. Treatment at an academic hospital explained 15% to 32% of the racial disparity and was the most potent mediator. LIMITATIONS: This study was limited by its retrospective design and failure to capture all meaningful mediators. CONCLUSIONS: Black, Hispanic, and other colorectal cancer patients experience treatment delays when compared to white patients. Equalization of the mediators used in this study could reduce treatment delays by 20% to 43% depending on the racial/ethnic group. Future research should identify other causes of racial disparities in treatment delay and intervene accordingly. See Video Abstract at http://links.lww.com/DCR/B871 . FACTORES MEDIADORES ENTRE LA RAZA Y EL TIEMPO HASTA EL TRATAMIENTO EN EL CNCER COLORECTAL: ANTECEDENTES:Investigaciones anteriores sobre disparidades han demostrado que los pacientes de minorías raciales subrepresentados tienen peores resultados de cáncer colorrectal y que experimentan retrasos innecesarios en el tiempo de tratamiento. Estos retrasos pueden explicar los peores resultados del cáncer colorrectal para los pacientes de minorías y servir como un marcador de desigualdades en nuestro sistema de salud.OBJETIVO:Este estudio tiene como objetivo cuantificar los mecanismos que contribuyen a esta disparidad en el retraso del tratamiento.DISEÑO:Este es un análisis retrospectivo de pacientes con cáncer colorrectal que se sometieron a resección electiva entre 2004 y 2017. Se utilizó un análisis de mediación de inferencia causal utilizando el marco contra factual para estimar hasta qué punto las disparidades raciales entre los factores del paciente explican las disparidades raciales en el tiempo hasta el tratamiento. Los mediadores incluyeron ingresos económicos, educación, comorbilidades, seguro médico y tipo de hospital.AJUSTES:Este estudio se realizó en hospitales que participan en la Base de datos nacional del cáncer.PACIENTES:Se incluyeron pacientes con cáncer colorrectal en estadio I-III, ≥18 años, que se sometieron a resección electiva entre 2004 y 2017.PRINCIPALES RESULTADOS MEDIDAS:Las principales mediciones fueron el efecto indirecto de los mediadores entre la raza y el retraso en el tratamiento.RESULTADOS:De los 504,405 pacientes (370,051 de colon, 134,354 rectal), 10%, 5%, 4% eran negros, hispanos, y otros, respectivamente. En modelos multivariables, en comparación con los pacientes blancos, estos pacientes tenían un 25%, 27%, y 17% más de probabilidades de retrasar el tratamiento. Los análisis de medición sugirieron que el 43%, 20%, 31% del retraso del tratamiento entre, respectivamente, podría eliminarse si una intervención igualara los ingresos económicos, la educación, las comorbilidades, el seguro médico y el tipo de hospital a los de los pacientes blancos. El tratamiento en un hospital académico demostró entre el 15% y el 32% de la disparidad racial y fue el mediador más potente.LIMITACIONES:Este estudio estuvo limitado por su diseño retrospectivo; falla en capturar a todos los mediadores significativos.CONCLUSIONES:Los pacientes negros, hispanos y otros con cáncer colorrectal experimentan retrasos en el tratamiento en comparación con los pacientes blancos. La igualación de los mediadores utilizados en este estudio podría reducir los retrasos en el tratamiento en un 20-43%, según el grupo racial / étnico. Las investigaciones futuras deberían identificar otras causas de disparidades raciales en el retraso del tratamiento e intervenir sobre ellas.

A shortened course of Amoxicillin/Clavulanate is the preferred antibiotic treatment after surgery for perforated appendicitis in children.

BACKGROUND/PURPOSE: Despite evidence supporting short course outpatient antibiotic treatment following appendectomy for perforated appendicitis, evidence of real-world implementation and consensus for antibiotic choice is lacking. We therefore aimed to compare outpatient antibiotic treatment regimens in a national cohort. METHODS: We identified children who underwent surgery for perforated appendicitis between 2010 and 2018 using the PearlDiver database and compared 45-day disease-specific readmission between children who received shortened (5-8 days) versus prolonged (10-14 day) total antibiotic courses (inpatient intravenous and/or oral) completed with outpatient Amoxicillin/Clavulanate versus Ciprofloxacin/Metronidazole, and compared antibiotic type (5-14 days) to each other. RESULTS: 4916 children were identified, 2001 (90.0%) treated with Amoxicillin/Clavulanate (5-14 days), 381 (19.0%) with shortened (5-8 days), 1464 (73.2%) with prolonged (10-14 days) courses. 222 (10.0%) were treated with Ciprofloxacin/Metronidazole, 44 (19.8%) with shortened, 174 (78.4%) with prolonged courses. Freedom from readmission was not different between prolonged and shortened course whether they received Amoxicillin/Clavulanate (adjusted hazard ratio [AHR] 1.54, 95%CI 0.95-2.5) or Ciprofloxacin/Metronidazole (AHR 3.49, 95%CI 0.45-27.3). Antibiotic type did not affect readmission rate (Amoxicillin/Clavulanate versus Ciprofloxacin/Metronidazole, AHR 1.21, 95%CI 0.71-2.05). CONCLUSION: Prolonged antibiotic regimens are routinely prescribed despite evidence suggesting shorter courses and antibiotic choice are not associated with greater treatment failure. As it is better tolerated, we recommend a shortened course of Amoxicillin/Clavulanate for oral management of perforated appendicitis. STUDY DESIGN: Retrospective. LEVEL OF EVIDENCE: Level III.

Low Preoperative Serum Creatinine is Common and Associated With Poor Outcomes After Nonemergent Inpatient Surgery.

OBJECTIVE: To assess the association between low preoperative serum creatinine and postoperative outcomes. BACKGROUND: The association between low creatinine and poor surgical outcomes is not well understood. METHODS: We identified patients with creatinine in the 7 days preceding nonemergent inpatient surgery in the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2020. Multivariable logistic regression was used to examine the association between creatinine and 30-day mortality and major complications. RESULTS: Of 1,809,576 patients, 27.8% of males and 23.5% of females had low preoperative serum creatinine, 14.6% experienced complications, and 1.2% died. For males, compared with the reference creatinine of 0.85 to 1.04, those with serum creatinine ≤0.44 had 55% increased odds of mortality [ adjusted odds ratio (aOR), 1.55; 95% CI, 1.29-1.86] and 82% increased odds of major complications (aOR, 1.82; 95% CI, 1.69-1.97). Similarly, for females, compared with the reference range of 0.65 to 0.84, those with serum creatinine ≤0.44 had 49% increased odds of mortality (aOR, 1.49; 95% CI, 1.32-1.67) and 76% increased odds of major complications (aOR, 1.76; 95% CI, 1.70-1.83). These associations persisted for the total cohort, among those with mildly low albumin, and for those with creatinine values measured 8 to 30 days preoperatively. CONCLUSIONS: A low preoperative creatinine is common and associated with poor outcomes after nonemergent inpatient surgery. A low creatinine may help identify high-risk patients who may benefit from further evaluation and optimization.

Association Between Mental Health Conditions and Postoperative Complications After Gender-Affirming Surgery.

This cohort study assesses whether postoperative complications are associated with having been diagnosed with a mental health condition in patients who have undergone gender-affirming surgery.

Social determinants of health Z-codes and postoperative outcomes after colorectal surgery: A national population-based study.

BACKGROUND: We sought to evaluate the impact of social determinants of health (SDOH) on postoperative outcomes following colorectal surgery. METHODS: This retrospective cohort study used PearlDiver-Mariner, an all-payer insurance claims database. Patients who underwent colectomy or proctectomy between 2010 and 2020 were included. SDOH were identified using International Classification of Diseases diagnosis codes. Outcomes were compared using multivariable regression models. RESULTS: The 30-day postoperative complication rate among 333,387 patients (mean age, 59 years; 58% female) was 27%. Approximately 5% of patients reported at least one SDOH at baseline. SDOH were not associated with length of stay but were associated with higher odds of 30-day postoperative complications (OR:1.16, 95% CI:1.12-1.20), including urinary tract infection (OR:1.27, 95% CI:1.20-1.35) anastomotic leak (OR:1.22, 95% CI:1.16-1.28), pneumonia (OR:1.19, 95% CI:1.11-1.27), deep vein thrombosis (OR:1.13, 95% CI:1.02-1.23), sepsis (OR:1.12, 95% CI:1.07-1.18), disruption of wound (OR:1.12, 95% CI:1.03-1.21), and acute kidney injury (OR:1.04, 95% CI:0.99-1.10). CONCLUSIONS: SDOH Z-codes were associated with worse postoperative complications following colorectal surgery and may help target high-risk patients.

Factors Mediating Racial/Ethnic Disparities in Delayed Treatment of Breast Cancer.

BACKGROUND: Despite improvements, disparities in breast cancer care have led to an inequitable distribution of treatment delays and worse outcomes among patients with breast cancer. This study aimed to quantify the contribution of mediators that may explain racial/ethnic disparities in breast cancer treatment delays. PATIENTS AND METHODS: We conducted a retrospective analysis of patients from the National Cancer Database with stage I-III breast cancer who underwent surgical resection. Mediation analyses estimated the extent to which racial/ethnic disparities in the distribution of patient characteristics account for racial/ethnic disparities in delayed treatment. RESULTS: Of the 1,349,715 patients with breast cancer included, 10%, 5%, and 4% were Black, Hispanic, and other non-white race/ethnicity, respectively. Multivariable models showed that patients in these racial/ethnic groups had 73%, 81%, and 24% increased odds of having a treatment delay relative to white patients. Mediation analyses suggested that 15%, 19%, and 15% of the treatment delays among Black, Hispanic, and other non-white race/ethnicity patients, respectively, are explained by disparities in education, comorbidities, insurance, and facility type. Therefore, if these mediators had been distributed equally among all races/ethnicities, a reduction of 15-19% in the delayed treatment disparities experienced by minority patients would have been observed. Academic facility type was the factor that could yield the largest reduction in time to treatment disparities, contributing to 8-13% of racial/ethnic disparities. CONCLUSIONS: Patients with breast cancer who identified as Black, Hispanic, and other non-white races/ethnicities are exposed to longer treatment delays relative to white patients. Efforts to equalize mediators could remove substantial portions of racial/ethnic disparities in delayed treatment.

Trends in Skin Melanoma Burden: Findings From the Global Burden of Disease Study.

Background: Melanoma is the third most common skin cancer and the leading cause of skin cancer mortality. This study sought to investigate trends in melanoma incidence, mortality, and burden of disease. Methods: The authors assessed the records of the Global Burden of Disease Study 2017 to extract information about the incidence, mortality, and disability adjusted life years (DALY) related to melanoma during 1990-2017 in the US and other countries based on their socio-demographic index (SDI). Results: Melanoma incidence in the US increased 1.6 times, although the difference was not statistically significant. For patients over the age of 60, the incidence was significantly increased by 1.72 to 164.6 times. Mortality was relatively stable during the study period; however, it was increased for patients over 65 years of age (range: 1.03 to 70 times), although not statistically significant. Mortality-to-incidence ratio was decreased, but the difference was not statistically significant. For patients over 75 years of age, DALYs were statistically significantly increased by 1.34 to 1.71 times. Conclusions: This study highlights differences in melanoma incidence and mortality from 1990-2017. Physicians involved in melanoma care should be aware of these changes in order to anticipate care needs.

Disparities in patient and system factors explain racial/ethnic disparities in delayed time to treatment in muscle invasive bladder cancer.

PURPOSE: Treatment delays in muscle invasive bladder cancer (MIBC) have been shown to be associated with worse outcomes. While every attempt is made to provide adequate treatment expeditiously, Black and Hispanic patients often experience delays at a higher rate than their White counterparts. This study aims to quantify the mechanisms that contribute to this disparity in treatment delay. METHODS: Retrospective analysis of clinical T-stages II-IVa MIBC patients who underwent surgical resection from 2004 to 2017 in the National Cancer Database. A causal inference mediation analysis using the counterfactual framework was implemented to estimate the extent to which racial/ethnic disparities in patient and system factors explain the racial/ethnic disparities in time to treatment. Mediators included income, education, comorbidities, insurance, and hospital type. RESULTS: Among 22,864 patients who met inclusion criteria, 7%, 3%, 2% were of Black, Hispanic, and Other race/ethnicity, respectively. In multivariable models, compared to White patients, Black, and Hispanic patients were associated with 26% (odds ratio = 1.26, 95% confidence interval = 1.12-1.42) and 29% (odds ratio = 1.29, 95% confidence interval = 1.07-1.55) increased odds of having a treatment delay relative to White patients. Mediation analyses suggested that 49% and 26% the treatment delay among Black and Hispanic patients, respectively, could be removed if an intervention equalized the distribution of academic treatment, education, and insurance status to that of White patients. Treatment at an academic hospital and education were the mediators that explained the largest portion of the racial/ethnic disparity in treatment delay. CONCLUSION: Black and Hispanic MIBC patients experience treatment delays when compared to White patients. Intervening upon patient and system factors could reduce substantial treatment delays. Future research is needed to identify other causes of disparities in treatment delays and may help population health initiatives to address racial/ethnic disparities in clinical settings.

The Association Between Bariatric Surgery and Psychiatric Disorders: a National Cohort Study.

PURPOSE: Previous studies have shown that bariatric surgery reduces the risk of cardiovascular outcomes. Less is known about the effects of bariatric surgery on psychiatric disorders. This cohort study compared the differential risk of psychiatric disorders between those who did and did not undergo bariatric surgery, from before until after the surgery. MATERIALS AND METHODS: We used PearlDiver-Mariner, a national all-payor claims database. Patients were followed for 1 year before and after the index date and a difference-in-differences (DiD) study design was executed. RESULTS: We included 56,661 bariatric surgery patients matched to 56,661 individuals with obesity. Among bariatric surgery patients, the risk of psychiatric was 18% 1 year before and increased to 70% 1 year after surgery. Among individuals with obesity, the risk of psychiatric disorders also increased from 1 year before to 1 year after, but by less (21% versus 46%). DiD analysis suggested that bariatric surgery was associated with a 27 percentage point differential increase in the risk of psychiatric disorders across all patients, representing a 135% relative increase. Results using 3 years as the pre- and post-periods lead to similar inferences. CONCLUSION: Preexisting psychiatric disorders are similarly prevalent among bariatric surgery patients and individuals with obesity. The prevalence of psychiatric disorders increased over time for both groups, but to a larger extent among bariatric surgery patients. Adequate treatment for psychiatric disorders and appropriate implementation of behavioral health interventions may be needed to reduce the burden of psychiatric disorders following bariatric surgery.

Is robotic utilization associated with increased minimally invasive colorectal surgery rates? Surgeon-level evidence.

BACKGROUND: It is unclear whether robotic utilization has increased overall minimally invasive colorectal surgery rates or if robotics is being adopted instead of laparoscopy. The goal was to evaluate whether increasing robotic surgery utilization is associated with increased rates of overall colorectal minimally invasive surgery. METHODS: The Statewide Planning and Research Cooperative System (New York) was used to identify patients undergoing elective colectomy or proctectomy from 2009 to 2015. Individual surgeons were categorized as having increasing or non-increasing robotic utilization (IRU or non-IRU, respectively) based on the annual increase in the proportion of robotic surgery performed. The odds of surgical approach across the study period were evaluated with multinomial regression. RESULTS: Among 72,813 resections from 2009 to 2015, minimally invasive-surgery increased (47-61%, p < 0.0001). For colectomy, overall minimally invasive-surgery rates increased (54-66%, p < 0.0001), laparoscopic remained stable (53-54%), and robotics increased (1-12%). For proctectomy, overall minimally invasive-surgery rates increased (22-43%, p < 0.0001), laparoscopic remained stable (20-21%), and robotics increased (2-22%). Over the study period, 2487 surgeons performed colectomies. Among 156 surgeons with IRU for colectomies, robotics increased (2-29%), while laparoscopy decreased (67-44%), and open surgery decreased (31-27%). Overall, surgeons with IRU performed minimally invasive colectomies 73% of the time in 2015 versus 69% in 2009. Over the study period, 1131 surgeons performed proctectomies. Among 94 surgeons with IRU for proctectomies, robotics increased (3-42%), while laparoscopy decreased (25-15%), and open surgery decreased (73-44%). Overall, surgeons with IRU performed minimally invasive proctectomy 56% of the time in 2015 versus 27% in 2009. Patients in the latter study period had 57% greater odds of undergoing robotic surgery. CONCLUSIONS: Overall, minimally invasive colorectal resections increased from 2009 to 2015 largely due to increasing robotic utilization, particularly for proctectomies.

A New Bibliometric Index: The Top 100 Most Disruptive and Developmental Publications in Colorectal Surgery Journals.

BACKGROUND: A new bibliometric index called the disruption score was recently proposed to identify innovative and paradigm-changing publications. OBJECTIVE: The goal was to apply the disruption score to the colorectal surgery literature to provide the community with a repository of important research articles. DESIGN: This study is a bibliometric analysis. SETTINGS: The 100 most disruptive and developmental publications in Diseases of the Colon & Rectum, Colorectal Disease, International Journal of Colorectal Disease, and Techniques in Coloproctology were identified from a validated data set of disruption scores and linked with the iCite National Institutes of Health tool to obtain citation counts. MAIN OUTCOME MEASURES: The primary outcomes measured were the disruption score and citation count. RESULTS: We identified 12,127 articles published in Diseases of the Colon & Rectum (n = 8109), International Journal of Colorectal Disease (n = 1912), Colorectal Disease (n = 1751), and Techniques in Coloproctology (n = 355) between 1954 and 2014. Diseases of the Colon & Rectum had the most articles in the top 100 most disruptive and developmental lists. The disruptive articles were in the top 1% of the disruption score distribution in PubMed and were cited between 1 and 671 times. Being highly cited was weakly correlated with high disruption scores (r = 0.09). Developmental articles had disruption scores that were more strongly correlated with citation count (r = 0.18). LIMITATIONS: This study is subject to the limitations of bibliometric indices, which change over time. DISCUSSION: The disruption score identified insightful and paradigm-changing studies in colorectal surgery. These studies include a wide range of topics and consistently identified editorials and case reports/case series as important research. This bibliometric analysis provides colorectal surgeons with a unique archive of research that can often be overlooked but that may have scholarly significance.

Diseases of the Colon and Rectum representó la mayoría de las publicaciones dentro de la lista de los 100 mas desestabilizadores y de desarrollo. Esta literatura desestabilizadora se encuentra en el principal 1% de la distribución de la puntuacón desestabilizadora en PubMed y se citaron de 1 a 671 veces. El ser citado con frecuencia se relacionó vagamente con las puntuaciones de desastibilización (r = 0.09). Los artículos de desarrollo tuvieron puntuaciones de desestabilización que estuvieron muy correlacionados con la cuantificación de las citas (r = 0.18).LIMITACIONES:Las sujetas a las limitaciones de los índices bibliométricos, que se modifican en el tiempo.DISCUSION:La putuación de desestabilicación identificó trabajos perspicaces, pragmáticos y modificadores de paradigmas en cirugía colorrectal. Es de interés identificar que se incluyeron una gran variedad de temas y en forma consistente editoriales, reportes de casos y series de casos que representaron una investigación importante. Este análisis bibliométrico aporta a los cirujanos colorrectales de un acervo de investigación único que puede con frecuencia pasarse por alto, y sin embargo tener una gran importancia académica.

Keep Them on the Table: Outcomes Are Improved After Minimally Invasive Colectomy Despite Longer Operative Times in Patients With High-Risk Colon Cancer.

BACKGROUND: For high-risk patients, traditional surgical dogma advises open operations, with short operative times, to "get them off the table" instead of longer minimally invasive surgery approaches. OBJECTIVE: The aim of this study was to compare postoperative outcomes in patients with high-risk colon cancer undergoing elective longer minimally invasive surgery operations compared with shorter open operations. DESIGN: Retrospective comparative cohort study. SETTINGS: Interventions were performed in hospitals participating in the national surgical database. PATIENTS: The National Surgical Quality Improvement Program database was used to identify patients with colon cancer with ASA class 3 to 4 undergoing right and sigmoid colectomy between 2012 and 2017. MAIN OUTCOME MEASURES: Thirty-day postoperative outcomes were compared between short open and long minimally invasive groups. RESULTS: A total of 3775 patients were identified as having undergone long minimally invasive right colectomy and short open right colectomy (33% open, 67% minimally invasive surgery), and 1042 patients were identified as having undergone long minimally invasive sigmoid colectomy and short open sigmoid colectomy (36% open, 64% minimally invasive). Patients undergoing long minimally invasive right colectomy had significantly lower rates of overall morbidity, severe adverse events, mortality, superficial surgical site infections, and wound disruptions, as well as discharge to a higher level of care and shorter length of stay ( p < 0.05). Patients undergoing long minimally invasive sigmoid colectomy had decreased rates of overall morbidity, severe adverse events, and length of stay, as well as discharge to a higher level of care compared with the patients undergoing short open sigmoid colectomy ( p < 0.05). LIMITATIONS: This study was limited by the retrospective nature and standardized outcome measures. CONCLUSIONS: In high-risk patients undergoing colectomy for colon cancer, outcomes were worse with shorter open compared with longer minimally invasive surgery operations. Focus should shift from getting patients "off the table" faster to longer, but safer, minimally invasive surgery in high-risk patients. See Video Abstract at http://links.lww.com/DCR/B642 . MANTNGALOS SOBRE LA MESA HAY MEJORES RESULTADOS DESPUS DE COLECTOMA MNIMAMENTE INVASIVA A PESAR DE TIEMPOS QUIRRGICOS MS PROLONGADOS EN PACIENTES CON CNCER DE COLON DE ALTO RIESGO: ANTECEDENTES:Para los pacientes de alto riesgo, el dogma quirúrgico tradicional aconseja operaciones abiertas, con tiempos quirúrgicos cortos, con el fin de "sacarlos de la mesa" en lugar de enfoques quirúrgicos mínimamente invasivos más prolongados.OBJETIVO:El objetivo de este estudio fue comparar los resultados posoperatorios en pacientes electivos de cáncer de colon de alto riesgo sometidos a operaciones de cirugía mínimamente invasiva más prolongadas en comparación con operaciones abiertas más cortas.DISEÑO:Los resultados posoperatorios de pacientes con cáncer de colon con clase 3-4 de la Sociedad Americana de Anestesiología sometidos a colectomía derecha o sigmoidea se compararon en un análisis multivariado. Se comparó el grupo de colectomía derecha abierta corta (tiempo operatorio <116 minutos) y colectomía derecha mínimamente invasiva larga (tiempo operatorio> 132 minutos). También se compararon la colectomía sigmoidea abierta corta (tiempo operatorio <127 minutos) y la colectomía sigmoidea mínimamente invasiva larga (tiempo operatorio> 161 minutos).ESCENARIO:Las intervenciones se realizaron en hospitales participantes en la base de datos quirúrgica nacional.PACIENTES:La base de datos del Programa Nacional de Mejoramiento de la Calidad Quirúrgica se utilizó para identificar a los pacientes con cáncer de colon con clase 3-4 de la Sociedad Americana de Anestesiología sometidos a colectomía derecha y sigmoidea entre 2012-2017.PRINCIPALES MEDIDAS DE RESULTADO:Se compararon los resultados posoperatorios a los treinta días entre el grupo de procedimientos abiertos cortos y el de mínimamente invasivos largos.RESULTADOS:Se identificó un total de 3.775 pacientes sometidos a colectomía derecha mínimamente invasiva larga y colectomía derecha abierta corta (33% abierta, 67% cirugía mínimamente invasiva) y se identificaron 1042 pacientes sometidos a colectomía sigmoidea mínimamente invasiva larga y colectomía sigmoidea abierta corta (36% abierta, 64% mínimamente invasiva). Los pacientes con colectomía derecha larga mínimamente invasiva tuvieron significativamente menor morbilidad general, eventos adversos graves, mortalidad, infecciones superficiales del sitio quirúrgico, dehiscencia de herida, alta a un nivel más alto de atención y estadía más corta ( p <0.05). Los pacientes con colectomía sigmoidea mínimamente invasiva prolongada tuvieron menor morbilidad general, eventos adversos graves, duración de la estadía y alta a un nivel más alto de atención en comparación con los pacientes con colectomía sigmoidea abierta corta ( p <0.05).LIMITACIONES:Este estudio estuvo limitado por la naturaleza retrospectiva y las medidas de resultado estandarizadas.CONCLUSIONES:En los pacientes de alto riesgo sometidos a colectomía por cáncer de colon, los resultados fueron peores con operaciones abiertas más cortas en comparación con operaciones mínimamente invasivas más largas. El enfoque debe pasar de hacer que los pacientes "salgan rápido de la mesa quirúrgica" a una cirugía mínimamente invasiva más prolongada pero más segura, en pacientes de alto riesgo.
