Introduction: Enteral nutrition is commonly placed via percutaneous endoscopic gastrostomy (PEG) or radiologically inserted gastrostomy (RIG) techniques. This study compared perioperative outcomes of PEG and RIG in adults with dysphagia caused by cerebral infarction., Methods: Adult stroke patients who underwent either PEG or RIG between 2018 and 2020 at a tertiary care center were reviewed retrospectively. Differences in baseline characteristics between PEG and RIG patients were adjusted using entropy-balanced weights. Multivariable weighted logistic and linear regressions were subsequently developed to evaluate the independent association between RIG and outcomes of interest., Results: 217 stroke patients met inclusion criteria, of whom 37 (17.0%) received PEG and 180 (83.0%) received RIG. Compared to PEG, patients with RIG were more commonly Medicare beneficiaries and had a higher burden of comorbidities as measured by the Charlson comorbidity index. Time to achieve goal feeds was comparable between PEG and RIG (3 d [interquartile range 2-5] vs 4 d [interquartile range 3-5], respectively, P = 0.059). After multivariate adjustment, RIG was associated with significantly lower odds of reoperation (adjusted odds ratio [AOR] 0.10, 95% CI 0.02-0.50, P = 0.005), cerebrovascular accident (AOR 0.24, 95% CI 0.00-0.74, P = 0.030), and intensive care unit admission (AOR 0.14, 95% CI 0.03-0.70, P = 0.017). Risk factors for in-hospital mortality among RIG included arrhythmia (AOR 6.54, 95% CI 1.67-15.48, P = 0.009), myocardial infarction (AOR 4.78, 95% CI 2.25-10.23, P = 0.009), and obesity (AOR 4.48, 95% CI 1.03-9.61, P = 0.047)., Conclusions: While both techniques are effective methods of enteral feeding in stroke patients, RIG may confer lower perioperative morbidity. Local referral patterns and individual patient comorbidities could influence outcomes following PEG or RIG, necessitating careful patient selection., (Copyright © 2024 Elsevier Inc.

Background: The recurrence rate of paraesophageal hernia repair (PEHR) is high with reported rates of recurrence varying between 25 and 42%. We present a novel approach to PEHR that involves the visualization of a critical view to decrease recurrence rate. Our study aims to investigate the outcomes of PEHR following the implementation of a critical view., Methods: This is a single-center retrospective study that examines operative outcomes in patients who underwent PEHR with a critical view in comparison to patients who underwent standard repair. The critical view is defined as full dissection of the posterior mediastinum with complete mobilization of the esophagus to the level of the inferior pulmonary vein, visualization of the left crus of the diaphragm as well as the left gastric artery while the distal esophagus is retracted to expose the spleen in the background. Bivariate chi-squared analysis and multivariable logistic and linear regressions were used for statistical analysis., Results: A total of 297 patients underwent PEHR between 2015 and 2023, including 207 with critical view and 90 with standard repair which represents the historic control. Type III hernias were most common (48%) followed by type I (36%), type IV (13%), and type II (2.0%). Robotic-assisted repair was most common (65%), followed by laparoscopic (22%) and open repair (14%). Fundoplications performed included Dor (59%), Nissen (14%), Belsey (5%), and Toupet (2%). Patients who underwent PEHR with critical view had lower hernia recurrence rates compared to standard (9.7% vs 20%, P < .01) and lower reoperation rates (0.5% vs 10%, P < .001). There were no differences in postoperative complications on unadjusted bivariate analysis; however, adjusted outcomes revealed a lower odds of postoperative complications in patients with critical view (AOR .13, 95% CI .05-.31, P < .001)., Conclusion: We present dissection of a novel critical view during repair of all types of paraesophageal hernia that results in reproducible, consistent, and durable postoperative outcomes, including a significant reduction in recurrence and reoperation., (© 2024.

Background: Elderly patients can experience torpid hospitalization that is often characterized by malnutrition. In this setting, enteral feeding may facilitate improvement in nutritional status. This study aimed to compare the perioperative outcomes between elderly (age of ≥65 years old) and nonelderly (age of <65 years old) patients undergoing elective enteral access placement., Methods: Adult patients who underwent enteral access procedures between 2018 and 2020 at a tertiary care facility were retrospectively reviewed. Differences in baseline characteristics between nonelderly and elderly patients were adjusted using entropy-balanced weights. Subsequently, multivariate logistic and linear regression models were developed to evaluate the association between elderly status and outcomes of interest., Results: Overall, 914 patients with enteral access met the inclusion criteria, of whom 471 (51.5%) were elderly. Elderly patients more commonly received percutaneous gastrostomy and had a higher burden of comorbidities as measured using the Charlson Comorbidity Index than nonelderly patients. Multivariate risk adjustment generated a strongly balanced distribution of baseline covariates between patient groups. After adjustment, despite no significant association with inhospital mortality, reoperation, or time to feeding goals, elderly status was linked to an approximately 8-day reduction in length of stay (95% CI, -14.28 to -2.30; P = .007) and significantly lower odds of total parenteral nutrition (adjusted odds ratio [AOR], 0.59; 95% CI, 0.37-0.94; P = .026) and nonelective readmission (AOR, 0.65; 95% CI, 0.49-0.86; P = .003). In addition, elderly status was associated with significantly greater odds of nonhome discharge (AOR, 1.58; 95% CI, 1.17-2.13; P = .003)., Conclusion: Despite having more comorbidities than their nonelderly counterparts, elderly patients experienced favorable nutritional and perioperative outcomes after enteral access placement., (Copyright © 2024 Society for Surgery of the Alimentary Tract.

Background: The link between obesity and adverse cardiovascular events is well-established. With the rising prevalence of metabolic and bariatric surgery (MBS), a greater number of patients undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) may present with preoperative therapeutic anticoagulation (AC)., Objectives: This study evaluated perioperative outcomes of SG and RYGB in patients on preoperative AC., Setting: Patients reported to the 2015-2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database., Methods: Adults undergoing primary SG or RYGB with and without preoperative anticoagulation (SG-AC or RYGB-AC and non-SG-AC or non-RYGB-AC, respectively) were analyzed from the 2015-2021 MBSAQIP database. Differences in baseline characteristics by AC status for each MBS were adjusted using entropy-balanced weights. Multivariable logistic and linear regressions were developed to analyze the independent association between AC and outcomes of interest., Results: Of 1,178,090 patients included, 72.0% (n = 850,682) had SG and 28.0% (n = 327,408) had RYGB, of which 1.8% (n = 15,021) and 1.9% (n = 6201) had AC, respectively. Compared to non-SG-AC and non-RYGB-AC, both SG-AC and RYGB-AC encountered higher absolute 30-day rates of anastomotic leak, deep vein thrombosis and gastrointestinal bleeding. Following multivariable adjustment, SG-AC was associated with significantly greater odds of adverse cardiovascular events, anastomotic leak, gastrointestinal bleeding, and greater operative length and length of stay. RYGB-AC was associated with higher odds of readmission, unplanned ICU admission, and ED visit., Conclusions: While preoperative AC may confer distinct outcomes between SG and RYGB, this 7-year study of MBSAQIP demonstrated an overall association with greater postoperative morbidity. Management of MBS patients with preoperative AC requires consideration of thrombohemorrhagic risks., (Copyright © 2024 American Society for Metabolic and Bariatric Surgery. Published by Elsevier Inc.

Introduction: Patients admitted with principal cardiac diagnosis (PCD) can encounter difficult inpatient stays that are often marked by malnutrition. In this setting, enteral feeding may improve nutritional status. This study examined the association of PCD with perioperative outcomes after elective enteral access procedures., Methods: Adult patients who underwent enteral access procedures between 2018 and 2020 at a tertiary care institution were reviewed retrospectively. Differences in baseline characteristics between patients with and without PCD were adjusted using entropy balancing. Multivariable logistic and linear regressions were subsequently developed to evaluate the association between PCD and nutritional outcomes, perioperative morbidity and mortality, length of stay, and nonelective readmission after enteral access., Results: 912 patients with enteral access met inclusion criteria, of whom 84 (9.2%) had a diagnosis code indicating PCD. Compared to non-PCD, patients with PCD more commonly received percutaneous endoscopic gastrostomy by general surgery and had a higher burden of comorbidities as measured by the Charlson comorbidity index. Multivariable risk adjustment generated a strongly balanced distribution of baseline covariates between patient groups (standardized differences ranged from -2.45 × 10 -8 to 3.18 × 10 8 ). After adjustment, despite no significant association with in-hospital mortality, percentage change prealbumin, length of stay, or readmission, PCD was associated with an approximately 2.25-day reduction in time to meet goal feeds (95% CI -3.76 to -0.74, P = 0.004) as well as decreased odds of reoperation (adjusted odds ratio 0.28, 95% CI 0.09-0.86, P = 0.026) and acute kidney injury (adjusted odds ratio 0.24, 95% CI 0.06-0.91, P = 0.035)., Conclusions: Despite having more comorbidities than non-PCD, adult enteral access patients with PCD experienced favorable nutritional and perioperative outcomes., (Copyright © 2024 Elsevier Inc.

Background: Cumulative sum (CUSUM) analysis is a valuable tool for quantifying the learning curve of surgical teams by detecting significant changes in operative length. However, there is limited research evaluating the learning curve of laparoscopic techniques in low-resource settings. The objective of this study is to evaluate the learning curve for laparoscopic appendectomy within a single surgical team in Senegal., Methods: This was a single-center prospective study conducted from May 1, 2018, to August 31, 2023 of patients who underwent laparoscopic appendectomy at a tertiary care institution in West Africa. The AAST classification was used to describe the severity of appendicitis. Parameters studied included age, sex, operative length, conversion rate, and postoperative outcomes. To quantify the learning curve, CUSUM analysis of operative length was performed., Results: A total of 81 patients were included. The mean age was 26.7 years (range 11-70 years) with a sex ratio of 1.9. Pre-operative severity according to AAST was Grade I in 75.4% (n = 61), Grade III in 7.4% (n = 6), Grade IV in 6.1% (n = 5), and Grade V in 11.1% (n = 9). Conversion occurred in 5 cases (6.1%). The average operative length was 76.8 min (range 30-180 min) and the average length of hospitalization was 2.7 days (range 1-13 days). Morbidity was observed in 3.7% (n = 3) and there were no deaths. The CUSUM analysis showed that a steady operative length was achieved after 28 procedures, with decreasing operative lengths thereafter., Conclusion: Surgeons in our setting overcame the learning curve for laparoscopic appendectomy after performing 28 procedures. Moreover, laparoscopic appendectomy is safe and feasible throughout the learning curve. CUSUM analysis should be applied to other laparoscopic procedures and individualized by surgical teams to improve surgical performance and patient outcomes in low-resource settings., (© 2024.

Introduction: Generative artificial intelligence (AI) chatbots have recently been posited as potential sources of online medical information for patients making medical decisions. Existing online patient-oriented medical information has repeatedly been shown to be of variable quality and difficult readability. Therefore, we sought to evaluate the content and quality of AI-generated medical information on acute appendicitis., Methods: A modified DISCERN assessment tool, comprising 16 distinct criteria each scored on a 5-point Likert scale (score range 16-80), was used to assess AI-generated content. Readability was determined using the Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL) scores. Four popular chatbots, ChatGPT-3.5 and ChatGPT-4, Bard, and Claude-2, were prompted to generate medical information about appendicitis. Three investigators independently scored the generated texts blinded to the identity of the AI platforms., Results: ChatGPT-3.5, ChatGPT-4, Bard, and Claude-2 had overall mean (SD) quality scores of 60.7 (1.2), 62.0 (1.0), 62.3 (1.2), and 51.3 (2.3), respectively, on a scale of 16-80. Inter-rater reliability was 0.81, 0.75, 0.81, and 0.72, respectively, indicating substantial agreement. Claude-2 demonstrated a significantly lower mean quality score compared to ChatGPT-4 (p = 0.001), ChatGPT-3.5 (p = 0.005), and Bard (p = 0.001). Bard was the only AI platform that listed verifiable sources, while Claude-2 provided fabricated sources. All chatbots except for Claude-2 advised readers to consult a physician if experiencing symptoms. Regarding readability, FKGL and FRE scores of ChatGPT-3.5, ChatGPT-4, Bard, and Claude-2 were 14.6 and 23.8, 11.9 and 33.9, 8.6 and 52.8, 11.0 and 36.6, respectively, indicating difficulty readability at a college reading skill level., Conclusion: AI-generated medical information on appendicitis scored favorably upon quality assessment, but most either fabricated sources or did not provide any altogether. Additionally, overall readability far exceeded recommended levels for the public. Generative AI platforms demonstrate measured potential for patient education and engagement about appendicitis., (© 2024. The Author(s).)

Background: Non-alcoholic steatohepatitis (NASH) is one of the leading indications for liver transplantation (LT) in the United States. As with the current obesity epidemic, the incidence of NASH continues to rise. However, the impact of broad utilization of bariatric surgery (BS) for patients with NASH is unknown, particularly in regard to mitigating the need for LT., Methods: Markov decision analysis was performed to simulate the lives of 20,000 patients with obesity and concomitant NASH who were deemed ineligible to be waitlisted for LT unless they achieved a body mass index (BMI) < 35 kg/m 2 . Life expectancy following medical weight management (MWM) and sleeve gastrectomy (SG) were estimated. Base case patients were defined as having NASH without fibrosis and a pre-intervention BMI of 45 kg/m 2 . Sensitivity analysis of initial BMI was performed., Results: Simulated base case analysis patients who underwent SG gained 14.3 years of life compared to patients who underwent MWM. One year after weight loss intervention, 9% of simulated MWM patients required LT compared to only 5% of SG patients. Survival benefit for SG was observed above a BMI of 32.2 kg/m 2 ., Conclusion: In this predictive model of 20,000 patients with obesity and concomitant NASH, surgical weight loss is associated with a reduction in the progression of NASH, thereby reducing the need for LT. A reduced BMI threshold of 32 kg/m 2 for BS may offer survival benefit for patients with obesity and NASH., (© 2024.

Introduction: The advent of generative artificial intelligence (AI) dialogue platforms and large language models (LLMs) may help facilitate ongoing efforts to improve health literacy. Additionally, recent studies have highlighted inadequate health literacy among patients with cardiac disease. The aim of the present study was to ascertain whether two freely available generative AI dialogue platforms could rewrite online aortic stenosis (AS) patient education materials (PEMs) to meet recommended reading skill levels for the public., Methods: Online PEMs were gathered from a professional cardiothoracic surgical society and academic institutions in the USA. PEMs were then inputted into two AI-powered LLMs, ChatGPT-3.5 and Bard, with the prompt "translate to 5th-grade reading level". Readability of PEMs before and after AI conversion was measured using the validated Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook Index (SMOGI), and Gunning-Fog Index (GFI) scores., Results: Overall, 21 PEMs on AS were gathered. Original readability measures indicated difficult readability at the 10th-12th grade reading level. ChatGPT-3.5 successfully improved readability across all four measures (p < 0.001) to the approximately 6th-7th grade reading level. Bard successfully improved readability across all measures (p < 0.001) except for SMOGI (p = 0.729) to the approximately 8th-9th grade level. Neither platform generated PEMs written below the recommended 6th-grade reading level. ChatGPT-3.5 demonstrated significantly more favorable post-conversion readability scores, percentage change in readability scores, and conversion time compared to Bard (all p < 0.001)., Conclusion: AI dialogue platforms can enhance the readability of PEMs for patients with AS but may not fully meet recommended reading skill levels, highlighting potential tools to help strengthen cardiac health literacy in the future., (© 2024.

Objective: Immersive virtual reality (IVR) can be utilized to provide low cost and easily accessible simulation on all aspects of surgical education. In addition to technical skills training in surgery, IVR simulation has been utilized for nontechnical skills training in domains such as clinical decision-making and pre-operative planning. This systematic review examines the current literature on the effectiveness of IVR for nontechnical skill acquisition in surgical education., Design: A literature search was performed using MEDLINE, EMBASE, and Web of Science for primary studies published between January 1, 1995 and February 9, 2022. Four reviewers screened titles, abstracts, full texts, extracted data, and analyzed included studies to answer 5 key questions: How is IVR being utilized in nontechnical skills surgical education? What is the methodological quality of studies? What technologies are being utilized? What metrics are reported? What are the findings of these studies?, Results: The literature search yielded 2340 citations, with 12 articles included for qualitative synthesis. Of included articles, 33% focused on clinical decision-making and 67% on anatomy/pre-operative planning. Motion sickness was a recorded metric in 25% of studies, with an aggregate incidence of 13% (11/87). An application score was reported in 33% and time to completion in 16.7%. A commercially developed application was utilized in 25%, while 75% employed a noncommercial application. The Oculus Rift was used in 41.7% of studies, HTC Vive in 25%, Samsung Gear in 16.7% of studies, Google Daydream in 8%, and 1 study did not report. The mean Medical Education Research Quality Instrument (MERSQI) score was 10.3 ± 2.3 (out of 18). In all studies researching clinical decision-making, participants preferred IVR to conventional teaching methods and in a nonrandomized control study it was found to be more effective. Averaged across all studies, mean scores were 4.33 for enjoyment, 4.16 for utility, 4.11 for usability, and 3.73 for immersion on a 5-point Likert scale., Conclusions: The IVR nontechnical skills applications for surgical education are designed for clinical decision-making or anatomy/pre-operative planning. These applications are primarily noncommercially produced and rely upon a diverse array of HMDs for content delivery, suggesting that development is primarily coming from within academia and still without clarity on optimal utilization of the technology. Excitingly, users find these applications to be immersive, enjoyable, usable, and of utility in learning. Although a few studies suggest that IVR is additive or superior to conventional teaching or imaging methods, the data is mixed and derived from studies with weak design. Motion sickness with IVR remains a complication of IVR use needing further study to determine the cause and means of mitigation., (Copyright © 2023 Association of Program Directors in Surgery.

Purpose: For patients with obesity and congestive heart failure (CHF) who require heart transplantation (HT), aggressive weight loss has been associated with ventricular remodeling, or subclinical alterations in left and right ventricular structure that affect systolic function. Many have suggested offering metabolic and bariatric surgery (MBS) for these patients. As such, we evaluated the role of MBS in HT for patients with obesity and CHF using predictive modelling techniques., Materials and Methods: Markov decision analysis was performed to simulate the life expectancy of 30,000 patients with concomitant obesity, CHF, and 30% ejection fraction (EF) who were deemed ineligible to be waitlisted for HT unless they achieved a BMI < 35 kg/m 2 . Life expectancy following diet and exercise (DE), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG) was estimated. Base case patients were defined as having a pre-intervention BMI of 45 kg/m 2 . Sensitivity analysis of initial BMI was performed., Results: RYGB patients had lower rates of HT and received HT quicker when needed. Base case patients who underwent RYGB gained 2.2 additional mean years survival compared with patients who underwent SG and 10.3 additional mean years survival compared with DE. SG patients gained 6.2 mean years of life compared with DE., Conclusion: In this simulation of 30,000 patients with obesity, CHF, and reduced EF, MBS was associated with improved survival by not only decreasing the need for transplantation due to improvements in EF, but also increasing access to HT when needed due to lower average BMI., (© 2023.

Introduction: Interventional radiologic, endoscopic, and surgical approaches are commonly utilized to establish durable enteral access in adult patients. The purpose of this study is to examine differences in nutritional outcomes in a large cohort of patients undergoing enteral access creation., Methods: Adult patients who underwent enteral access procedures by interventional radiologists, gastroenterologists, and surgeons between 2018 and 2020 at a single institution were reviewed. Included access types were percutaneous endoscopic gastrostomy (PEG), open or laparoscopic gastrostomy, laparoscopic jejunostomy, and percutaneous gastrostomy (perc-G), percutaneous jejunostomy , or primary gastrojejunostomy., Results: 912 patients undergoing enteral access cases met the criteria for inclusion. PEGs and perc-Gs were the most common procedures. PEGs had higher Charlson scores (4.5 [3.0-6.0] versus 2.0 [1.0-2.0], P = 0.007) and lower starting albumin (3.0 [2.6-3.4] versus 3.6 [3.5-3.8] g/dL, P < 0.0001). Time to goal feeds (4 [2-6] vs 4 [3-5] d, P = 0.970), delta prealbumin (3.6 [0-6.5] versus 6.2 [2.3-10] mg/L, P = 0.145), time to access removal (160 [60-220] versus 180 [90-300] d, P = 0.998), and enteral access-related complications (19% versus 16%, P = 0.21) between PEG and perc-G were similar and differences were not statistically significant. A greater percent change in prealbumin was noted for perc-G (10 [-3-20] versus 41.7% [11-65], P = 0.002)., Conclusions: Despite having higher Charlson scores and worse preoperative nutrition, there is a similar incidence of enteral access-related complications, time to goal feeds, delta prealbumin, or time to access removal between PEG and perc-G patients. Our data suggest that access approach should be made on an individual basis, accounting for anatomy and technical feasibility., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Introduction: Laparoscopy has a clear patient benefit related to postoperative morbidity but may not be as commonly performed in low-and middle-income countries. The decision to convert to laparotomy can be complex and involve factors related to the surgeon, patient, and procedure. The objective of this work is to analyze the factors associated with conversion in laparoscopic surgery in a low-resource setting., Methods: This is a single-center prospective study of patients who underwent laparoscopic surgery between May 1, 2018 and October 31, 2021. The parameters studied were age, sex, body mass index (BMI), intraoperative complication (e.g., accidental enterotomy, hemorrhage), equipment malfunction (e.g., technical failure of the equipment, break in CO 2 supply line), operating time, and conversion rate., Results: A total of 123 laparoscopic surgeries were performed. The average age of patients was 31.2 years (range 11-75). The procedures performed included appendix procedures (48%), followed by gynecological (18.7%), gallbladder (14.6%), digestive (10.56%), and abdominal procedures (4%). The average length of hospitalization was 3 days (range 1-16). Conversion to laparotomy was reported in 8.9% (n = 11) cases. Equipment malfunction was encountered in 9.8% (n = 12) cases. Surgical complications were noted in 11 cases (8.9%). Risk factors for conversion were shown to be BMI > 25 kg/m 2 (OR 4.6; p = 0.034), intraoperative complications (OR 12.6; p = 0.028), and equipment malfunction (OR 9.4; p = 0.002)., Conclusion: A better understanding of the underlying factors associated with high conversion rates, such as overweight/obesity, intraoperative complications, and equipment failure, is the first step toward surgical planning to reduce postoperative morbidity in low-resource settings., (© 2023.

Background: Laparoscopic cholecystectomy is the most common laparoscopic procedure performed in the US and a key component of general surgery training. Surgical trainees frequently access YouTube for educational walkthroughs of surgical procedures. This study aims to evaluate the educational quality of YouTube video walkthroughs on laparoscopic cholecystectomy by using the LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) video assessment tool., Methods: A YouTube search was conducted using "laparoscopic cholecystectomy." Results were sorted by relevance, and the top 100 videos were gathered. Videos with patient education or concomitant procedures were excluded. Included videos were categorized as Physician (produced by an individual physician), Academic (produced by a university or medical school), Commercial (produced by a surgical company), and Society (produced by a professional surgical society) and were rated by 3 investigators using the LAP-VEGaS video assessment tool (0-18)., Results: In all, 33 videos met the selection criteria. The average LAP-VEGaS score was 7.96 ± 3.95, and inter-rater reliability was .86. Academic videos demonstrated a significantly higher mean LAP-VEGaS score than Commercial (10.69 ± 3.54 vs 5.25 ± 2.38, P = .033). Most academic videos failed to provide formal case presentations (63%), patient positioning (50%), intraoperative findings (50%), graphic aids (63%), and operative time (75%)., Conclusion: This is the first study to evaluate the quality of YouTube video walkthroughs on LC using the LAP-VEGaS tool. Despite demonstrating higher LAP-VEGaS scores than other categories, video walkthroughs provided by academic institutions still lack several essential educational criteria for this procedure, highlighting areas of improvement for educators., (Copyright © 2023 Elsevier Inc.

Purpose: Patients increasingly access online materials for health-related information. Using validated assessment tools, we aim to assess the quality and readability of online information for patients considering incisional hernia (IH) repair., Methods: The top three online search engines (Google, Bing, Yahoo) were searched in July 2022 for "Incisional hernia repair" and "Surgical hernia repair". Included websites were classified as academic, hospital-affiliated, commercial, and unspecified. The quality of information was assessed using the Journal of the American Medical Association (JAMA) benchmark criteria (0-4), DISCERN instrument (16-80), and the presence of Health On the Net code (HONcode) certification. Readability was assessed using the Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL) tests., Results: 25 unique websites were included. The average JAMA and DISCERN scores of all websites were 0.68 ± 1.02 and 36.50 ± 10.91, respectively. Commercial sites showed a significantly higher DISCERN mean score than academic sites (p = 0.034), while no significant difference was demonstrated between other website categories. 3 (12%) websites reported HONcode certification and had significantly higher JAMA (p = 0.016) and DISCERN (p = 0.045) mean scores than sites without certification. Average FRE and FKGL scores were 39.84 ± 13.11 and 10.62 ± 1.76, respectively, corresponding to college- and high school-level comprehensibility., Conclusions: Our findings suggest online patient resources on IH repair are of poor overall quality and may not be comprehensible to the public. Patients accessing internet resources for additional information on IH repair should be made aware of these inadequacies and directed to sites bearing HONcode certification., Competing Interests: Declarations of competing interest None., (Copyright © 2022 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Background: Despite its common nature, there is no data on the educational quality of publicly available laparoscopic jejunostomy training videos. The LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) video assessment tool, released in 2020, has been developed to ensure that teaching videos are of appropriate quality. This study applies the LAP-VEGaS tool to currently available laparoscopic jejunostomy videos., Methods: A retrospective review of YouTube ® videos was conducted for "laparoscopic jejunostomy." Included videos were rated by three independent investigators using LAP-VEGaS video assessment tool (0-18). Wilcoxon rank-sum test was used to evaluate differences in LAP-VEGaS scores between video categories and date of publication relative to 2020. Spearman's correlation test was performed to measure association between scores and length, number of views and likes., Results: 27 unique videos met selection criteria. Academic and physician video walkthroughs did not demonstrate a significant difference in median scores (9.33 IQR 6.33, 14.33 vs. 7.67 IQR 4, 12.67, p = 0.3951). Videos published after 2020 demonstrated higher median scores than those published before 2020 (13 IQR 7.5, 14.67 vs. 5 IQR 3, 9.67, p = 0.0081). A majority of videos failed to provide patient position (52%), intraoperative findings (56%), operative time (63%), graphic aids (74%), and audio/written commentary (52%). A positive association was demonstrated between scores and number of likes (r s  = 0.59, p = 0.0011) and video length (r s  = 0.39, p = 0.0421), but not number of views (r s  = 0.17, p = 0.3991)., Conclusion: The majority of available YouTube ® videos on laparoscopic jejunostomy fail to meet the basic educational needs of surgical trainees, and there is no difference between those produced by academic centers or independent physicians. However, there has been improvement in video quality following the release of the scoring tool. Standardization of laparoscopic jejunostomy training videos with the LAP-VEGaS score can ensure that videos are of appropriate educational value with logical structure., (© 2023.

Introduction: The advent of laparoscopy has significantly reduced the morbidity associated with the majority of abdominal surgeries. In Senegal, the first studies evaluating this technique were published in the 1980s. The objective of this systematic review is to assess the evolution of laparoscopy research in Senegal., Methods: A search of PubMed and Google Scholar was carried out without limit of publication date. The keywords used were "senegal" AND "laparoscop*". Duplicates were removed, and remaining articles were assessed for selection criteria. We included all articles about laparoscopy published in Senegal. The parameters studied in each included article were the place and year of study, average age, sex ratio, assessed indications and results., Results: 41 Studies published between 1984 and 2021 met selection criteria. The average age of patients was 33 years (range 4.7-63). The sex ratio was 0.33. The main indications for laparoscopy according to the studies were: benign gastrointestinal disorders in 11 studies (26.8%), abdominal emergencies in 9 studies (22%), gallbladder surgery in 5 studies (12.2%), benign gynecological pathology in 6 studies (14.6%), malignant gynecological pathology in 2 studies (4.9%), diagnostic laparoscopy in 2 studies (4.9%), groin hernia repair in 2 studies (4.9%) and testicular pathology in 1 study (2.4%). Overall mortality was estimated at 0.9% (95% CI 0.6-1.3) and overall morbidity for all complications was estimated at 5% (95% CI 3.4-6.9)., Conclusions: This systematic review showed a predominance of the laparoscopy publications from the capital in Dakar with favorable outcomes. This technique should be popularized in the different regions of the country and its indications expanded., (© 2023.

Background: As patients seek online health information to supplement their medical decision-making, the aim of this study is to assess the quality and readability of internet information on the left ventricular assist device (LVAD)., Methods: Three online search engines (Google, Bing, and Yahoo) were searched for "LVAD" and "Left ventricular assist device." Included websites were classified as academic, foundation/advocacy, hospital-affiliated, commercial, or unspecified. The quality of information was assessed using the JAMA benchmark criteria (0-4), DISCERN tool (16-80), and the presence of Health On the Net code (HONcode) accreditation. Readability was assessed using the Flesch Reading Ease score., Results: A total of 38 unique websites were included. The average JAMA and DISCERN scores of all websites were 0.82 ± 1.11 and 52.45 ± 13.51, respectively. Academic sites had a significantly lower JAMA mean score than commercial (p < 0.001) and unspecified (p < 0.001) websites, as well as a significantly lower DISCERN, mean score than commercial sites (p = 0.002). HONcode certification was present in 6 (15%) websites analyzed, which had significantly higher JAMA (p < 0.001) and DISCERN (p < 0.016) mean scores than sites without HONcode certification. Readability was fairly difficult and at the level of high school students., Conclusions: The quality of online information on the LVAD is variable, and overall readability exceeds the recommended level for the public. Patients accessing online information on the LVAD should be referred to sites with HONcode accreditation. Academic institutions must provide higher quality online patient literature on LVADs., (© 2022 International Center for Artificial Organ and Transplantation (ICAOT) and Wiley Periodicals LLC.)

Purpose: Vitamin C (VC) is implicated in many physiological pathways. Vitamin C deficiency (VCD) can compromise the health of patients with metabolic and bariatric surgery (patients). As symptoms of VCD are elusive and data on VCD in patients is scarce, we aim to characterize patients with measured VC levels, investigate the association of VCD with other lab abnormalities, and create predictive models of VCD using machine learning (ML)., Methods: A retrospective chart review of patients seen from 2017 to 2021 at a tertiary care center in Northeastern USA was conducted. A 1:4 case mix of patients with VC measured to a random sample of patients without VC measured was created for comparative purposes. ML models (BayesNet and random forest) were used to create predictive models and estimate the prevalence of VCD patients., Results: Of 5946 patients reviewed, 187 (3.1%) had VC measures, and 73 (39%) of these patients had VC<23 μmol/L(VCD. When comparing patients with VCD to patients without VCD, the ML algorithms identified a higher risk of VCD in patients deficient in vitamin B1, D, calcium, potassium, iron, and blood indices. ML models reached 70% accuracy. Applied to the testing sample, a "true" VCD prevalence of ~20% was predicted, among whom ~33% had scurvy levels (VC<11 μmol/L)., Conclusion: Our models suggest a much higher level of patients have VCD than is reflected in the literature. This indicates a high proportion of patients remain potentially undiagnosed for VCD and are thus at risk for postoperative morbidity and mortality., (© 2023.

Background: Compared to controlled donation after cardiac death (cDCD), uncontrolled DCD (uDCD) kidney transplantation remains an underutilized resource in the United States. However, it is unclear whether long-term allograft outcomes following uDCD are inferior to that of cDCD kidney transplantation., Methods: From January 1995 to January 2018, the OPTN/UNOS database was queried to discover all reported cases of uDCD and cDCD kidney transplantation. Primary non-function, delayed graft function, ten-year graft and patient survival were compared among uDCD and cDCD patients., Results: Rates of primary non-function (4.0% [uDCD] vs. 1.8% [cDCD], P < 0.001) and delayed graft function (51.1% [uDCD] vs. 41.7% [cDCD], P < 0.001) were higher following uDCD transplant. However, ten-year graft survival (47.5% [uDCD] vs. 48.4% [cDCD], P = 0.21) and patient survival were similar to cDCD transplantation (59.4% [uDCD] vs. 59.2% [cDCD], P = 0.32)., Conclusion: Although initial allograft outcomes are inferior following uDCD, long-term durability of uDCD kidney allografts is on par to cDCD transplantation. Kidney allografts derived by uDCD may be a viable and durable option to increase the donor pool., Competing Interests: Declaration of competing interest All authors have no conflicts of interest to declare., (Copyright © 2022 Elsevier Inc.

Background and Objectives: We aim to assess the quality and readability of online information available to patients considering cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC)., Methods: The top three search engines (Google, Bing, and Yahoo) were searched in March 2022. Websites were classified as academic, hospital-affiliated, foundation/advocacy, commercial, or unspecified. Quality of information was assessed using the JAMA benchmark criteria (0-4) and DISCERN tool (16-80), and the presence of a Health On the Net code (HONcode) seal. Readability was evaluated using the Flesch Reading Ease score., Results: Fifty unique websites were included. The average JAMA and DISCERN scores of all websites were 0.72 ± 1.14 and 39.58 ± 13.71, respectively. Foundation/advocacy websites had significantly higher JAMA mean score than commercial (p = 0.044), academic (p < 0.001), and hospital-affiliated websites (p = 0.001). Foundation/advocacy sites had a significantly higher DISCERN mean score than hospital-affiliated (p = 0.035) and academic websites (p = 0.030). The HONcode seal was present in 4 (8%) websites analyzed. Readability was difficult and at the level of college students., Conclusions: The overall quality of patient-oriented online information on CRS-HIPEC is poor and available resources may not be comprehensible to the general public. Patients seeking information on CRS-HIPEC should be directed to sites affiliated with foundation/advocacy organizations., (© 2022 Wiley Periodicals LLC.)

Background: Degenerative lumbar spondylolisthesis is one of the most common pathologies addressed by surgeons. Recently, data demonstrated improved outcomes with fusion in conjunction with laminectomy compared to laminectomy alone. However, given not all degenerative spondylolistheses are clinically comparable, the best treatment option may depend on multiple parameters. Specifically, the impact of spinopelvic alignment on patient reported and clinical outcomes following fusion versus decompression for grade I spondylolisthesis has yet to be explored., Purpose: This study assessed two-year clinical outcomes and one-year patient reported outcomes following laminectomy with concomitant fusion versus laminectomy alone for management of grade I degenerative spondylolisthesis and stenosis. The present study is the first to examine the effect of spinopelvic alignment on patient-reported and clinical outcomes following decompression alone versus decompression with fusion., Study Design/setting: Retrospective sub-group analysis of observational, prospectively collected cohort study., Patient Sample: 679 patients treated with laminectomy with fusion or laminectomy alone for grade I degenerative spondylolisthesis and comorbid spinal stenosis performed by orthopaedic and neurosurgeons at three medical centers affiliated with a single, tertiary care center., Outcome Measures: The primary outcome was the change in Patient-Reported Outcome Measurement Information System (PROMIS), Global Physical Health (GPH), and Global Mental Health (GMH) scores at baseline and post-operatively at 4-6 and 10-12 months postoperatively. Secondary outcomes included operative parameters (estimated blood loss and operative time), and two-year clinical outcomes including reoperations, duration of postoperative physical therapy, and discharge disposition., Methods: Radiographs/MRIs assessed stenosis, spondylolisthesis, pelvic incidence, lumbar lordosis, sacral slope, and pelvic tilt; from this data, two cohorts were created based on pelvic incidence minus lumbar lordosis (PILL), denoted as "high" and "low" mismatch. Patients underwent either decompression or decompression with fusion; propensity score matching (PSM) and coarsened exact matching (CEM) were used to create matched cohorts of "cases" (fusion) and "controls" (decompression). Binary comparisons used McNemar test; continuous outcomes used Wilcoxon rank-sum test. Between-group comparisons of changes in PROMIS GPH and GMH scores were analyzed using mixed-effects models; analyses were conducted separately for patients with high and low pelvic incidence-lumbar lordosis (PILL) mismatch., Results: 49.9% of patients (339) underwent lumbar decompression with fusion, while 50.1% (340) received decompression. In the high PLL mismatch cohort at 10-12 months postoperatively, fusion-treated patients reported improved PROs, including GMH (26.61 vs. 20.75, p<0.0001) and GPH (23.61 vs. 18.13, p<0.0001). They also required fewer months of outpatient physical therapy (1.61 vs. 3.65, p<0.0001) and had lower 2-year reoperation rates (12.63% vs. 17.89%, p=0.0442) compared to decompression-only patients. In contrast, in the low PLL mismatch cohort, fusion-treated patients demonstrated worse endpoint PROs (GMH: 18.67 vs. 21.52, p<0.0001; GPH: 16.08 vs. 20.74, p<0.0001). They were also more likely to require skilled nursing/rehabilitation centers (6.86% vs. 0.98%, p=0.0412) and extended outpatient physical therapy (2.47 vs. 1.34 months, p<0.0001) and had higher 2-year reoperation rates (25.49% vs. 14.71%,p=0.0152)., Conclusions: Lumbar laminectomy with fusion was superior to laminectomy in health-related quality of life and reoperation rate at two years postoperatively only for patients with sagittal malalignment, represented by high PILL mismatch. In contrast, the addition of fusion for patients with low-grade spondylolisthesis, spinal stenosis, and spinopelvic harmony (low PILL mismatch) resulted in worse quality of life outcomes and reoperation rates., (Copyright © 2022 Elsevier Inc.

Study Design: Retrospective observational study., Objective: To elucidate racial and socioeconomic factors driving preoperative disparities in spine surgery patients., Summary of Background Data: There are racial and socioeconomic disparities in preoperative health among spine surgery patients, which may influence outcomes for minority and low socioeconomic status (SES) populations., Methods: Presenting, postoperative day 90 (POD90), and 12-month (12M) outcome scores (PROMIS global physical and mental [GPH, GMH] and visual analog scale pain [VAS]) were collected for patients undergoing deformity arthrodesis or cervical, thoracic, or lumbar laminotomy or decompression/fusion; these procedures were the most common in our cohort. Social determinants of health for a patient's neighborhood (county, zip code, or census tract) were extracted from public databases. Multivariable linear regression with stepwise selection was used to quantify the association between a patient's preoperative GPH score and sociodemographic variables., Results: Black patients presented with 1 to 3 point higher VAS pain scores (7-8 vs. 5-6) and lower (worse) GPH scores (6.5-10 vs. 11-12) than White patients (P < 0.05 for all comparisons); similarly, lower SES patients presented with 1.5 points greater pain (P < 0.0001) and 3.5 points lower GPH (P < 0.0001) than high SES patients. Patients with lowest-quartile presenting GPH scores reported 36.8% and 37.5% lower (worse) POD-90 GMH and GPH scores than the highest quartile, respectively (GMH: 12 vs. 19, P < 0.0001; GPH: 15 vs. 24, P < 0.0001); this trend extended to 12 months (GMH: 19.5 vs. 29.5, P < 0.0001; GPH: 22 vs. 30, P < 0.0001). Reduced access to primary care (B = -1.616, P < 0.0001) and low SES (B = -1.504, P = 0.001), proxied by median household value, were independent predictors of worse presenting GPH scores., Conclusion: Racial and socioeconomic disparities in patients' preoperative physical and mental health at presentation for spine surgery are associated adversely with postoperative outcomes. Renewed focus on structural factors influencing preoperative presentation, including timeliness of care, is essential.Level of Evidence: 3., (Copyright © 2022 Wolters Kluwer Health, Inc.
