Comparison of Five-Day vs. Fourteen-Day Incubation of Cultures for Diagnosis of Periprosthetic Joint Infection in Hip Arthroplasty

Background: Periprosthetic joint infections (PJI) are among the most morbid complications in total hip arthroplasty (THA). The ideal incubation time, however, for intraoperative cultures for PJI diagnosis remains unclear. As such, the aim of this study was to determine if any differences existed in culture-positive rates and organism detection between five-day and fourteen-day cultures. Methods: This retrospective cohort study consisted of THA cases diagnosed with PJI performed between May 2014 and May 2020 at a single tertiary-care institution. Analyses compared five-day and fourteen-day cultures and carried out a pre-specified subgroup analysis by organism and PJI type. Results: A total of 147 surgeries were performed in 101 patients (57.1% females), of which 65% (n = 98) obtained five-day cultures and 34% (n = 49) obtained fourteen-day cultures. The positive culture rate was 67.3% (n = 99) with Staphylococcus aureus being the most common pathogen identified (n = 41 specimens, 41.4%). The positive culture rate was not significantly different between groups (66.3% five-day, 69.4% fourteen-day, p = 0.852). Fourteen-day cultures had a significantly longer time-to-positive culture (5.0 days) than five-day cultures (3.0 days, p < 0.001), a higher rate of fungi (5.6% vs. 0%), and a lower rate of Gram-negatives (4.5% vs. 18.7%, p = 0.016). Conclusions: Fourteen-day cultures did not increase the positivity rate, had higher rates of slow-growth pathogens, and had a longer time-to-positivization than five-day cultures. Prolonged culture holds may provide more thorough organism detection for PJI without increasing the diagnostic culture yield.

Modeling the population health impact of incorporating a multi-cancer early detection (MCED) test to existing cancer screening among immunocompromised individuals

Objective: To assess the screening efficiency of an MCED test added to SoC screening, compared to SoC screening alone, among immunocompromised individuals, and to estimate the diagnostic workup costs associated with positive screening results. Methods: We estimated the potential impact of cancer screening among immunocompromised individuals aged 50-79 years within the University of Utah Health system who underwent a stem cell/solid organ transplant or were diagnosed with a primary or secondary immunodeficiency disorder between January 2000 and February 2018. We derived cancer incidence rates from the Huntsman Cancer Institute Tumor Registry, and screening performance of SoC screening and an MCED test from published literature. Outcomes of screening efficiency included the true-positive to false-positive (TP:FP) ratio, diagnostic yield (DY), and cancer detection rate (CDR) for SoC screening alone and an incremental MCED test. Scenario and probabilistic sensitivity analyses were conducted. Results: Among 4932 immunocompromised individuals aged 50-79 years, we estimated that 2595 tests would be done under SoC screening and assumed that all individuals received an additional MCED test. Adding an MCED test to SoC screening substantially improved screening efficiency (TP:FP 1:1, DY 5.15/1000 tests, CDR 42.0%), compared to SoC screening alone (TP:FP 1:99, DY 1.23/1000 tests, CDR 5.3%), assuming an MCED test with 100% uptake. Our findings were also robust to parameter uncertainty. Conclusion: Adding an MCED test to complement existing screening may be a highly efficient strategy to increase the detection of cancers among immunocompromised individuals. These results could help to improve cancer prevention and detection efforts among individuals with multiple cancer risk factors.

Analysis of factors affecting the diagnostic yield for microbiologic diagnosis from percutaneous abdominal abscess drainage.

This study aimed to investigate the factors influencing the diagnostic yield of microbiologic diagnosis obtained through percutaneous abdominal abscess drainage procedures. We analyzed the influence of diverse clinical, radiological, and pre-procedural factors on the success of microbiologic diagnosis in this context. A retrospective analysis of patients who underwent percutaneous abdominal abscess drainage was performed to assess the factors affecting the diagnostic yield for microbiologic diagnosis. A total of 174 patients undergoing percutaneous abdominal abscess drainage was included. The use of antibiotics during the procedure and the spread of the abscess to other organs significantly increased the likelihood of obtaining a positive culture. Specifically, antibiotic use during the procedure raised the risk by up to 3.30-fold (OR = 3.30, 95% CI 1.48-7.65, p = 0.004), while abscess spread to another organ increased the risk by approximately 1.87-fold (OR = 1.87, 95% CI 0.98-3.61, p = 0.057). Additionally, abscesses containing air and abscesses with an air-fluid level were more common in patients with positive culture results. Other factors, such as gender, age, malignancy prevalence, and surgical history, did not significantly impact culture results. This study provides valuable insights into the factors affecting the diagnostic yield of microbiologic diagnosis from percutaneous abdominal abscess drainage. The findings underscore the importance of considering patient-specific variables and procedural aspects when planning and executing abscess drainage procedures. Further research can build upon these insights to develop evidence-based guidelines for optimizing the diagnostic yield of percutaneous abdominal abscess drainage procedures.

Cone Beam Computed Tomography improves location of transbronchial cryobiopsy in interstitial lung disease with limited extent.

transbronchial lung cryobiopsy has been recommended as an acceptable alternative to surgical approach for making a histopathological diagnosis in patients with Interstitial Lung Disease (ILD) of undetermined type. In limited diseases (especially if distributed along the sub-pleural region), sampling the specific area in which the pathological process is more represented could be challenging. Aim of the study was to determine the potential benefit of utilizing Cone Beam Computed Tomography (CBCT) guided cryobiopsy in patients with limited extent of ILD on CT scan and determine the single impact of each sequential biopsy progressively increasing the total number of biopsies. prospective analysis of patients with undetermined ILD and CT scan extent < 15 % undergoing cone beam CT - guided cryobiopsy. Each biopsy sample was collected and processed individually and pathologic interpretations were performed sequentially with the pathologist reformulating a new report with the addition of each sample (cumulative yield). 36 patients were enrolled. Pathological diagnostic yield was very good (> 90%), with almost 80% of diagnostic samples being the first one; when a second biopsy was performed, mean diagnostic yield increased with only a moderately significant difference. No severe adverse events were observed, pneumothorax was documented in 27.8 % of the cases. sequential individual collection and pathologic interpretation of each biopsy sample has confirmed the possibility of obtaining a diagnostic specimen at the first pass if transbronchial cryobiopsy is performed under cone-beam CT.

Study of microRNAs in Gingival Crevicular Fluid as Periodontal Diseases Biomarkers: Systematic Review

Aim: The aim of this review was to identify the microRNAs (miRNAs) present in gingival crevicular fluid (GCF) that can be used as biomarkers for the diagnosis of periodontal diseases, and to determine which of them has a higher diagnostic yield for periodontitis. Methods: The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines (reference number CRD42024544648). The Pubmed, Scopus, Cochrane Library, Embase, Web of Science, and Google Scholar databases were searched for clinical studies conducted in humans investigating periodontal diseases and miRNAs in GCF. The methodological quality of the articles was measured with the Newcastle–Ottawa Scale. Results: A total of 3222 references were identified in the initial literature search, and 16 articles were finally included in the review. The design of the studies was heterogeneous, which prevented a meta-analysis of the data. Most of the studies compared miRNA expression levels between patients with periodontitis and healthy controls. The most widely researched miRNA in periodontal diseases was miR-200b-3p and miR-146a. Conclusions: the miRNAs most studied are miR-146a, miR-200b, miR-223, miR-23a, and miR-203, and all of them except miR-203 have an acceptable diagnostic plausibility for periodontitis.

Molecular genetics in 1991 arrhythmia probands and 2782 relatives in Norway: Results from 17 years of genetic testing in a national laboratory.

The aim of this study was to explore the prevalence of likely pathogenic or pathogenic variants and assess the diagnostic yield from genetic testing for cardiac arrhythmias in Norway since 2003. Data from 1991 probands and 2782 relatives were retrospectively collected from the laboratory information management system at Unit for Cardiac and Cardiovascular Genetics, Oslo University hospital. Of 1991 probands, 57.4% were females, age at genetic testing was 33.1 (±22.7) years, and 32.5% were under the age of 18. A likely pathogenic or pathogenic variant (including 14 novel) was detected in 15.4% in total. Of the 2782 relatives, 53.7% were females, age at genetic testing was 35.6 (±22.5) years, 27.3% were under the age of 18, and 45.3% carried the family variant. Probands and relatives combined, 1/3356 persons in the Norwegian population were heterozygous for an arrhythmia-causing variant. The founder variant p.Q530X (NM_000218.2: c.1588C>T) in KCNQ1 accounted for 34% of all variants in Norway. In conclusion, genetic testing provided a genetic basis of the arrhythmia in 15.4% of the probands. Familial cascade screening identified four times as many variant-positive relatives, allowing early detection and prompt stratification of arrhythmic risk of those variant carriers.

Evaluation of Endocervical Curettage in Colposcopy in the Turkish Cervical Cancer Screening Program

Background/Objectives: To investigate the risk factors for CIN2+ lesions (cervical intraepithelial neoplasia 3 or worse) in endocervical curettage (ECC) and to evaluate the relationship between the addition of ECC to punch biopsy in terms of the yield of CIN2+ lesions. Methods: Between February 2018 and 2019, data on colposcopy results from 11,944 patients were gathered from the Cancer Department of the Turkish Ministry of Health across the country. A total of 6370 women whom were referred to colposcopy were included in this study. Risk factors were identified using both univariate and multivariate logistic analyses. Results: The median age was 42 years old (range, 30–65). ASC-H (atypical squamous cells-suggestive of high-grade squamous intraepithelial lesion)/HSIL (high-grade intraepithelial lesion) cytology (OR 7.648 95% CI (3.933–14.871)) and HPV (human papillomavirus)-16/18 infection (OR 2.541 95% CI (1.788–3.611)) were identified as risk factors for having CIN2+ lesions. CIN2+ diagnostic yield by ECC is only 1.2% all patients. CIN2+ diagnostic yield by punch biopsy and ECC are 9.7% and 6% of patients, respectively. A higher CIN2+ yield by ECC was observed with increasing age. Among cytology groups, ASC-H/HSIL has highest CIN2+ yield by ECC. Finally, in patients with incomplete visualization of the squamocolumnar junction (SCJ), ECC yields approximately twice as many CIN2+ lesions. Conclusions: ECC should be considered in cases of advanced patient age and in situations where the SCJ is not routinely visualized. In addition, evaluation of the endocervical canal is necessary in HPV-positive cases infected with HPV-16/18 types and in cases infected with HPV of any type but with cytological abnormalities.

Grading urothelial carcinoma with probe-based confocal laser endomicroscopy during flexible cystoscopy

PurposeUrothelial bladder cancer (UCB) care requires frequent follow-up cystoscopy and surgery. Confocal laser endomicroscopy (CLE) is a probe-based optical technique that can provide real-time microscopic evaluation with the potential for outpatient grading of UCB. This study aims to investigate the diagnostic accuracy and interobserver variability for the grading of UCB with CLE during flexible cystoscopy (fCLE).MethodsParticipants scheduled for transurethral resection of papillary bladder tumors were prospectively included for intra-operative fCLE. Exclusion criteria were flat lesions, fluorescein allergy or pregnancy. Two independent observers evaluated fCLE, classifying tumors as low- or high-grade urothelial carcinoma (LGUC/HGUC) or benign. Interobserver agreement was calculated with Cohens kappa (κ) and diagnostic accuracy with 2 × 2 tables. Histopathology was the reference test.ResultsHistopathology of 34 lesions revealed 14 HGUC, 14 LGUC and 6 benign tumors. Diagnostic yield for fCLE was 80–85% with a κ of 0.75. Respectively, sensitivity, specificity, NPV and PPV were: for benign tumors 0–20%, 96–100%, unmeasureable-50% and 87%, for LGUC 57–64%, 41–58%, 44–53% and 54–69% and for HGUC 38–57%, 56–68%, 38–57% and 56–68%, with an interobserver agreement of κ 0.61.ConclusionfCLE is currently insufficient to grade UCB.

Genetic Testing in Patients with Autoimmune Lymphoproliferative Syndrome: Experience of 802 Patients at Cincinnati Children’s Hospital Medical Center

Autoimmune lymphoproliferative syndrome (ALPS) is a rare genetic disorder featuring chronic lymphadenopathy, splenomegaly, cytopenias, and increased lymphoma risk. Differentiating ALPS from immunodeficiencies with overlapping symptoms is challenging. This study evaluated the performance and the diagnostic yield of a 15-gene NGS panel for ALPS at Cincinnati Children’s Hospital Medical Center. Samples from 802 patients submitted for ALPS NGS panel were studied between May 2014 and January 2023. A total of 62 patients (7.7%) had a definite diagnosis: 52/62 cases (84%) showed 37 unique pathogenic/likely pathogenic germline FAS variants supporting ALPS diagnosis (6.5%, 52/802). The ALPS diagnostic yield increased to 30% in patients who additionally fulfilled abnormal ALPS immunology findings criteria. 17/37 (46%) diagnostic FAS variants were novel variants reported for the first time in ALPS. 10/802 cases (1.2%) showed diagnostic findings in five genes (ADA2, CTLA4, KRAS, MAGT1, NRAS) which are related to autoimmune lymphoproliferative immunodeficiency (ALPID). Family studies enabled the reclassification of variants of unknown significance (VUS) and also the identification of at-risk family members of FAS-positive patients, which helped in the follow-up diagnosis and treatment. Alongside family studies, complete clinical phenotypes and abnormal ALPS immunology and Fas-mediated apoptosis results helped clarify uncertain genetic findings. This study describes the largest cohort of genetic testing for suspected ALPS in North America and highlights the effectiveness of the ALPS NGS panel in distinguishing ALPS from non-ALPS immunodeficiencies. More comprehensive assessment from exome or genome sequencing could be considered for undefined ALPS-U patients or non-ALPS immunodeficiencies after weighing cost, completeness, and timeliness of different genetic testing options.

Endoscopic Retrograde Cholangiopancreatography-Related Procedures for the Differential Diagnosis of Isolated Immunoglobin G4-Related Sclerosing Cholangitis and Perihilar Cholangiocarcinoma

Background/Purpose: Differential diagnosis of isolated immunoglobin (Ig)G4-related sclerosing cholangitis (IgG4-SC) and cholangiocarcinoma is challenging. We aimed to clarify the role of endoscopic retrograde cholangiography (ERCP)-related procedures in the differential diagnosis of isolated IgG4-SC and perihilar cholangiocarcinoma (PHCC). Methods: Seven patients with hilar-type isolated IgG4-SC diagnosed at Hiroshima University Hospital and sixty-five patients with surgically resected invasive PHCC were enrolled, and the diagnostic yields of intraductal ultrasonography (IDUS), peroral cholangioscopy (POCS), and pathological examinations were determined. Results: In six of seven (86%) patients with isolated IgG4-SC, the stricture was in the perihilar bile duct. IDUS showed that symmetrical wall thickening (40% vs. 5%, p = 0.04), homogeneous internal echo (80% vs. 5%, p < 0.001), and smooth outer margins (80% vs. 6%, p < 0.001) were more frequent in isolated IgG4-SC than in PHCC. POCS showed a smooth mucosal surface more frequent in isolated IgG4-SC (75% vs. 7%, p = 0.006). Only one patient had two pathological findings characteristic of IgG4-SC. The sensitivity for diagnosing PHCC was 81% using two or more combined sampling methods. Conclusions: Pathological examinations have limitations in the differential diagnosis of isolated-IgG4-SC and PHCC, and a diagnostic strategy that combines multiple ERCP-related procedures, including IDUS and POCS, is recommended.

Comparative evaluation of CT and MRI in the preoperative staging of colon cancer

The aim of this study is to compare the diagnostic performance of magnetic resonance imaging (MRI) against computed tomography (CT) in various aspects of local staging in colon cancer patients. This study was a prospective single arm diagnostic accuracy study. All consecutive adult patients with confirmed colon cancer that met the current criteria for surgical resection were considered as eligible. Diagnostic performance assessment included T (T1/T2 vs T3/T4 and < T3ab vs > T3cd) and N (N positive) staging, serosa and retroperitoneal surgical margin (RSM) involvement and extramural vascular invasion (EMVI). Imaging was based on a 3 Tesla MRI system and the evaluation of all sequences (T1, T2 and diffusion-weighted imaging-DWI series) by two independent readers. CT scan was performed in a 128 row multidetector (MD) CT scanner (slice thickness: 1 mm) with intravenous contrast. Pathology report was considered as the gold standard for local staging. Sensitivity (SE), specificity (SP), and area under the curve (AUC) were calculated for both observers. MRI displayed a higher diagnostic performance over CT in terms of T1/T2 vs T3/T4 (SE: 100% vs 83.9%, SP: 96.6% vs 81%, AUC: 0.825 vs 0.983, p < 0.001), N positive (p < 0.001) and EMVI (p = 0.023) assessment. An excellent performance of MRI was noted in the T3ab vs T3cd (CT AUCReader1: 0.636, AUCReader2: 0.55 vs MRI AUCReader1: 0.829 AUCReader2 0.846, p = 0.01) and RSM invasion diagnosis. In contrast to these, MRI did not perform well in the identification of serosa invasion. MRI had a higher diagnostic yield than CT in several local staging parameters.

Toward a Diagnostic Imaging Algorithm for Undifferentiated Pulsatile Tinnitus.

Decisions around the diagnostic evaluation for pulsatile tinnitus (PT) remain challenging. We describe the usage patterns and diagnostic accuracy of imaging modalities and propose an evidence-based diagnostic approach for undifferentiated PT. Retrospective. Single otology/neurotology clinic. Patients with PT presenting between 2009 and 2020. Sensitivity, specificity, diagnostic yield, and diagnostic accuracy. A total of 315 subjects met inclusion criteria (74% female, mean ± SD age = 52 ± 17 years). Subjects were divided into four cohorts based on exam findings: normal (n = 229), venous cohort (n = 34), arterial cohort (n = 16), and outer/middle ear pathology cohort (n = 40). In total, 53% of patients received a nonidiopathic diagnosis for PT. The most common identifiable cause was sigmoid sinus dehiscence (78%) in the venous cohort, carotid stenosis (36%) in the arterial cohort, and glomus tumor (56%) in the outer/middle ear pathology cohort. There was a higher diagnostic rate among patients with positive exam findings compared to those with unrevealing exams (p = 0.04). Imaging studies with the highest diagnostic yield were computed tomography (CT) venography (44%), formal angiography (42%), and magnetic resonance venography (40%); studies with the highest specificity were formal angiography (0.82), CT angiography (0.67), and CT venography (0.67). A diagnostic algorithm is proposed. Reaching a diagnosis in patients with PT requires a systematic approach, taking into account both clinical and radiographic information. Physical examination is a key first step for differentiating patients into venous, arterial, and other cohorts to narrow down the likely pathology and determine which radiographic studies have the highest yield and accuracy.

Diagnostic Yield and Model Prediction Using Wearable Patch Device in HFpEF.

Heart failure (HF) is a prevalent global health issue projected to escalate, notably in aging populations. The study aimed to identify predictive markers for Heart Failure with preserved Ejection Fraction (HFpEF). We scrutinized vital parameters like age, BMI, eGFR, and comorbidities like atrial fibrillation, coronary artery disease (CAD), diabetes mellites (DM). Evaluating phonocardiogram indicators-third heart sound(S3) and Systolic Dysfunction Index (SDI)-our logistic regression revealed age (≥ 65years), BMI (≥ 25 kg/m2), eGFR (<60 mL/min/1.73m2), CAD, DM, S3 intensity ≥5, and SDI ≥5 as HFpEF predictors, with AUC = 0.816 (p < .001). ROC diagnosis curve showed that the sensitivity, specificity and Youden's index J of the model were 0.755, 0.673 and 0.838, respectively. Nonetheless, further exploration is crucial to delineate the clinical applicability and constraints of these markers.

Additional yield of transbronchial cryo-node biopsy over endobronchial ultrasound-guided transbronchial needle aspiration for mediastinal lesions at a tertiary care center in India (COLD-FORCEPS-2 study)

Endobronchial ultrasound (EBUS)-guided mediastinal cryobiopsy is a new modality for sampling mediastinal lymph nodes. The data regarding the diagnostic yield and utility of mediastinal cryobiopsy is still limited. Consecutive patients who were undergoing EBUS-guided transbronchial needle aspiration (EBUS-TBNA) were recruited in this study. We subjected the enrolled patients to EBUS-guided mediastinal cryobiopsy after obtaining their informed consent. The final diagnosis was made with a clinical-pathological-radiological assessment and clinical-radiological follow-up. A total of 101 patients were enrolled in the study. Adequacy in sampling achieved in EBUS-TBNA was 92.07%, compared to 98.01% achieved in EBUS-TBNA with mediastinal cryobiopsy. Diagnostic yields achieved in EBUS-TBNA and EBUS-TBNA with mediastinal cryobiopsy were 67.32% and 86.13%, respectively (p=0.001). EBUS patterns failed to predict the utility of mediastinal crobiopsy. No significant complications were observed. To conclude, EBUS-guided mediastinal cryobiopsy improves yield in patients undergoing EBUS-TBNA.

Endoscopic Ultrasound-Guided Through-the-Needle Biopsy: A Narrative Review of the Technique and Its Emerging Role in Pancreatic Cyst Diagnosis

Pancreatic cystic lesions (PCLs) pose a diagnostic challenge due to their increasing incidence and the limitations of cross-sectional imaging and endoscopic-ultrasound-guided fine-needle aspiration (EUS-FNA). EUS-guided through the needle biopsy (EUS-TTNB) has emerged as a promising tool for improving the accuracy of cyst type determination and neoplastic risk stratification. EUS-TTNB demonstrates superior diagnostic performance over EUS-FNA, providing critical preoperative information that can significantly influence patient management and reduce unnecessary surgeries. However, the procedure has risks, with an overall adverse event rate of approximately 9%. Preventive measures and further prospective studies are essential to optimize its safety and efficacy. This review highlights the potential of EUS-TTNB to enhance the diagnostic and management approaches for patients with PCLs. It examines the current state of EUS-TTNB, including available devices, indications, procedural techniques, specimen handling, diagnostic yield, clinical impact, and associated adverse events.

Long-read sequencing and optical genome mapping identify causative gene disruptions in noncoding sequence in two patients with neurologic disease and known chromosome abnormalities.

Despite advances in next generation sequencing (NGS), genetic diagnoses remain elusive for many patients with neurologic syndromes. Long-read sequencing (LRS) and optical genome mapping (OGM) technologies improve upon existing capabilities in the detection and interpretation of structural variation in repetitive DNA, on a single haplotype, while also providing enhanced breakpoint resolution. We performed LRS and OGM on two patients with known chromosomal rearrangements and inconclusive Sanger or NGS. The first patient, who had epilepsy and developmental delay, had a complex translocation between two chromosomes that included insertion and inversion events. The second patient, who had a movement disorder, had an inversion on a single chromosome disrupted by multiple smaller inversions and insertions. Sequence level resolution of the rearrangements identified pathogenic breaks in noncoding sequence in or near known disease-causing genes with relevant neurologic phenotypes (MBD5, NKX2-1). These specific variants have not been reported previously, but expected molecular consequences are consistent with previously reported cases. As the use of LRS and OGM technologies for clinical testing increases and data analyses become more standardized, these methods along with multiomic data to validate noncoding variation effects will improve diagnostic yield and increase the proportion of probands with detectable pathogenic variants for known genes implicated in neurogenetic disease.

Prospective multicenter study to identify optimal target population for motorized spiral enteroscopy

Motorized spiral enteroscopy (MSE) enhances small bowel exploration, but the optimal target population for this technique is unknown. We aimed to identify the target population for MSE by evaluating its efficacy and safety, as well as detecting predictors of efficacy. A prospective multicenter observational study was conducted at 9 tertiary hospitals in Spain, enrolling patients between June 2020–2022. Analyzed data included demographics, indications for the procedure, exploration time, depth of maximum insertion (DMI), technical success, diagnostic yield, interventional yield, and adverse events (AE) up to 14 days from enteroscopy. Patients with prior gastrointestinal surgery, unsuccessful balloon enteroscopy and small bowel strictures were analyzed. A total of 326 enteroscopies (66.6% oral route) were performed in 294 patients (55.1% males, 65 years ± 21). Prior abdominal surgery was present in 50% of procedures (13.5% gastrointestinal surgery). Lower DMI (162 vs 275 cm, p = 0.037) and diagnostic yield (47.7 vs 67.5%, p = 0.016) were observed in patients with prior gastrointestinal surgery. MSE showed 92.2% technical success and 56.9% diagnostic yield after unsuccessful balloon enteroscopy (n = 51). In suspected small bowel strictures (n = 49), the finding was confirmed in 23 procedures (46.9%). The total AE rate was 10.7% (1.8% classified as major events) with no differences related to prior gastrointestinal/abdominal surgery, unsuccessful enteroscopy, or suspected small bowel strictures. The study demonstrates that MSE has a lower diagnostic yield and DMI in patients with prior gastrointestinal surgery but is feasible after unsuccessful balloon-enteroscopy and in suspected small bowel strictures without safety concerns.

Three-dimensional imaging of upper tract urothelial carcinoma improves diagnostic yield and accuracy

Three-dimensional imaging of upper tract urothelial carcinoma improves diagnostic yield and accuracy

Performance of pan-enteroscopy in children with intestinal failure due to short bowel syndrome: A single-center retrospective study.

In pediatric patients with intestinal failure (IF) due to short bowel syndrome, we hypothesized that young children, those with shorter residual small bowel and those with congenital malrotation of the bowel would be more likely to undergo pan-enteroscopy. We aimed to determine the feasibility and diagnostic yield of pan-enteroscopy in this cohort. We performed a single-center, retrospective study of pediatric patients with IF due to short bowel syndrome (SBS) who had undergone at least one GI endoscopic evaluation between January 1, 2018 and January 1, 2023. A pan-enteroscopy might have been possible in 381 of the 431 procedures (206 patients) reviewed. 44 (21%) patients underwent 54 pan-enteroscopies. Children with a residual bowel length <35 cm had higher odds of undergoing pan-enteroscopy (odds ratio [OR] 3.72, 95% confidence interval [CI] [1.32, 10.48], p = 0.01), as did patients with periprocedural glucagon-like peptide 2 (GLP-2) analog use (OR 4.30, 95% CI [1.24, 14.95], p = 0.02). Patients with diagnoses other than necrotizing enterocolitis (NEC) tended to be more likely to achieve a pan-enteroscopy (OR 2.73, 95% CI [0.95,7.88], p = 0.06). Evidence of gross and histopathologic abnormalities were found in 77.8% and 78% of the procedures, respectively. No complications were identified. In a large cohort of children with SBS, pan-enteroscopy was successfully performed in 14.2% of the procedures and microscopic abnormalities were common. Shorter residual bowel length, underlying diagnoses of non-NEC, and GLP-2 analog use were generally associated with successful pan-enteroscopy, independent of age and several other factors. These data suggest that pan-enteroscopy is feasible and of high-yield in a subset of patients with SBS.
