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: 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).)

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: 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.
