This article discusses the accuracy of the PanMayo endoscopic score in predicting long-term disease outcomes in ulcerative colitis (UC). The study compared the PanMayo score to other scoring systems such as MES, UCEIS, and Dublin. The results showed that the PanMayo score was positively associated with the risk of flare-up, the need for new biological treatment, and treatment escalation. It was also associated with the risk of colectomy in patients with active disease. The study suggests that the combined endoscopic assessment provided by the PanMayo score may be more precise in predicting disease outcomes in UC. [Extracted from the article]

Purpose: An idea of "double-crush syndrome", introduced by Upton and McComas, is a concept considered for cervical disc disease and the carpal tunnel syndrome. Similar hypothesis can be put forward for lumbar disc disease and the tarsal tunnel syndrome, though the occurrence of the latter has not been studied up to date. The aim of this study was to examine the occurrence of the tarsal tunnel syndrome among patients surgically treated for lumbar disc disease. Material and methods: Electroneurographical examination was performed in 53 in-patients of the Department of Neurosurgery, Medical University of Białystok, who were admitted for surgical treatment of lumbar disc herniation. Results: In 9 of 53 patients, (17%) the terminal latency of the response in the tibial nerve was elongated and the amplitude was depressed to exceed the normal reference range of these parameters, thus diagnosing the tarsal tunnel syndrome. The occurrence of the tarsal tunnel syndrome on the side affected by disc disease was much higher than on the unaffected side (13.2% vs. 7.5%, respectively). Conclusions: A significant sub-group of patients with lumbar disc disease subject to surgical treatment suffer also from impairment of the tibial nerve at the level of the tarsal tunnel. This is likely to affect the results of surgical treatment of disc disease: failed back surgery ought to be considered in respect of this finding. [ABSTRACT FROM AUTHOR]

Alterations to intestinal microbiota are assumed to occur in the pathogenesis of inflammatory bowel disease (IBD). This study aims to analyze the association of fecal microbiota composition, body composition, and lipid characteristics in patients with Crohn's disease (CD). In our cross-sectional study, patients with CD were enrolled and blood and fecal samples were collected. Clinical and endoscopic disease activity and body composition were assessed and laboratory tests were made. Fecal bacterial composition was analyzed using the shotgun method. Microbiota alterations based on obesity, lipid parameters, and disease characteristics were analyzed. In this study, 27 patients with CD were analyzed, of which 37.0% were obese based on visceral fat area (VFA). Beta diversities were higher in non-obese patients ( p < 0.001), but relative abundances did not differ. C. innocuum had a higher abundance at a high cholesterol level than Bacillota ( p = 0.001, p = 0.0034). Adlercreutzia , B. longum , and Blautia alterations were correlated with triglyceride levels. Higher Clostridia ( p = 0.009) and B. schinkii ( p = 0.032) and lower Lactobacillus ( p = 0.035) were connected to high VFA. Disease activity was coupled with dysbiotic elements. Microbiota alterations in obesity highlight the importance of gut microbiota in diseases with a similar inflammatory background and project therapeutic options.

Background: Choosing an optimal post-polypectomy management strategy of malignant colorectal polyps is challenging, and evidence regarding a surveillance-only strategy is limited., Aim: To evaluate long-term outcomes after endoscopic removal of malignant colorectal polyps., Methods: A single-center retrospective cohort study was conducted to evaluate outcomes after endoscopic removal of malignant colorectal polyps between 2010 and 2020. Residual disease rate and nodal metastases after secondary surgery and local and distant recurrence rate for those with at least 1 year of follow-up were investigated. Event rates for categorical variables and means for continuous variables with 95% confidence intervals were calculated, and Fisher's exact test and Mann-Whitney test were performed. Potential risk factors of adverse outcomes were determined with univariate and multivariate logistic regression models., Results: In total, 135 lesions (mean size: 22.1 mm; location: 42% rectal) from 129 patients (mean age: 67.7 years; 56% male) were enrolled. The proportion of pedunculated and non-pedunculated lesions was similar, with en bloc resection in 82% and 47% of lesions, respectively. Tumor differentiation, distance from resection margins, depth of submucosal invasion, lymphovascular invasion, and budding were reported at 89.6%, 45.2%, 58.5%, 31.9%, and 25.2%, respectively. Residual tumor was found in 10 patients, and nodal metastasis was found in 4 of 41 patients who underwent secondary surgical resection. Univariate analysis identified piecemeal resection as a risk factor for residual malignancy (odds ratio: 1.74; P = 0.042). At least 1 year of follow-up was available for 117 lesions from 111 patients (mean follow-up period: 5.59 years). Overall, 54%, 30%, 30%, 11%, and 16% of patients presented at the 1-year, 3-year, 5-year, 7-year, and 9-10-year surveillance examinations. Adverse outcomes occurred in 9.0% (local recurrence and dissemination in 4 patients and 9 patients, respectively), with no difference between patients undergoing secondary surgery and surveillance only., Conclusion: Reporting of histological features and adherence to surveillance colonoscopy needs improvement. Long-term adverse outcome rates might be higher than previously reported, irrespective of whether secondary surgery was performed., Competing Interests: Conflict-of-interest statement: All authors have no conflicts of interest to disclose., (©The Author(s) 2024.

Background: Different endoscopic scoring systems for assessing ulcerative colitis (UC) severity are available. However, most of them are not correlated with disease extent., Objectives: Our study aimed to compare the predictive value of the PanMay score versus the endoscopic Mayo (MES), Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and Dublin score in predicting long-term outcomes of UC., Design: This retrospective study enrolled consecutive UC patients who underwent colonoscopy before at least a 3-year follow-up., Methods: The PanMayo, MES, UCEIS, and Dublin scores and the baseline clinical and demographic characteristics of the participants were assessed. Endpoints were disease flare that required novel biological therapy, colectomy, and hospitalization. Patients were stratified using baseline clinical activity., Results: Approximately 62.8% of the 250 enrolled patients were in clinical remission. In these patients, the PanMayo, MES, and Dublin scores were positively associated with the risk of clinical flare. The MES score increased with clinical flare. The PanMayo score (>12 points), but not the MES score, was associated with the need for novel biological initiation and biological escalation. Furthermore, the Dublin and UCEIS scores of patients in remission who need novel biological treatment had a similar trend. Colectomy risk was associated with PanMayo and Dublin scores., Conclusion: The combined endoscopic assessment of disease extent and severity can be more accurate in predicting outcomes among patients with UC. PanMayo score can be utilized in addition to the existing scoring systems, thereby leading to a more accurate examination., Summary: UC endoscopic scores do not assess extension. Our study aimed to analyze the predictive value of the PanMayo score. Based on 250 patients, results showed that the long-term disease outcomes of UC could be predicted with the PanMayo score more accurately., Competing Interests: PW has been a speaker for Takeda, Pfizer, Janssen, Ferring, A.

Background: The inconclusive cytological findings of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) remain a major clinical challenge and often lead to treatment delays., Methods: Patients who had undergone EUS-FNA sampling for solid pancreas lesions between 2014 and 2021 were retrospectively enrolled. The "atypical" and "non-diagnostic" categories of the Papanicolaou Society of Cytopathology System were considered inconclusive and the "negative for malignancy" category of malignancy was suspected clinically. We determined the frequency and predictors of inconclusive cytological finding., Results: A total of 473 first EUS-FNA samples were included, of which 108 cases (22.83%) were inconclusive. Significant increases in the odds of inconclusive cytological findings were observed for lesions with a benign final diagnosis (OR 11.20; 95% CI 6.56-19.54, p < 0.001) as well as with the use of 25 G FNA needles (OR 2.12; 95% CI 1.09-4.01, p = 0.023) compared to 22 G needles. Furthermore, the use of a single EUS-FNA technique compared to the combined use of slow-pull and standard suction techniques (OR 1.70; 95% CI 1.06-2.70, p = 0.027) and less than three punctures per procedure led to an elevation in the risk of inconclusive cytology (OR 2.49; 95% CI 1.49-4.14, p < 0.001). Risk reduction in inconclusive cytology findings was observed in lesions between 2-4 cm (OR 0.40; 95% CI 0.23-0.68, p = 0.001) and >4 cm (OR 0.16; 95% CI 0.08-0.31, p < 0.001) compared to lesions ≤2 cm., Conclusions: The more than two punctures per EUS-FNA sampling with larger-diameter needle (19 G or 22 G) using the slow-pull and standard suction techniques in combination may decrease the probability of inconclusive cytological findings.

Endoscopic ultrasound is a minimally invasive modality that combines endoscopy with ultrasound, providing a possibility to visualize the wall of the gastrointestinal tract and adjacent tissues and organs. Since the development of the modality in the 1980s, advancements in endoscopic ultrasound technology have led to increasingly broadening indications: besides diagnostic indications, therapeutic indications have also expanded greatly. According to recent guidelines regarding rectal cancer staging, rectal ultrasonography is mainly considered to be a secondary imaging modality compared to magnetic resonance imaging. With the use of forward-viewing echoendoscopes and ultrasound miniprobes that can be inserted through the working channel of the endoscope, endoscopic ultrasound technology can be expanded to proximal, colonic areas as well. Rectal ultrasonography can also play an important role in the differential diagnosis of subepithelial lesions, in the detection of rectal varices, in the diagnosis of inflammatory bowel diseases as well as perianal complications. Diagnostic accuracy can further be improved with the addition of ultrasound-guided sampling in certain cases. Currently, therapeutic indications are more like promising possibilities, than part of everyday clinical practice, but this might change in the near future. The purpose of this review is to summarize the current indications of rectal ultrasound in the clinical practice, including diagnostic and therapeutic ones as well.
