Safety and Efficacy of Covered Self-Expandable Metallic Stent for Choledochojejunal Anastomotic Stricture: A Multi-Center Retrospective Cohort Study.

BACKGROUND: Benign choledochojejunal anastomotic stricture (CJS) is a complication of pancreaticoduodenectomy and choledochojejunostomy. Typically managed with endoscopic balloon dilatation, CJS has a high recurrence rate. Covered metallic stent (CMS) placement is a potential alternative; however, a comprehensive evaluation is lacking. OBJECTIVES: The aim of this study was to evaluate the treatment outcomes of CMS placement in patients with CJS. METHODS: We retrospectively analyzed patients who underwent balloon dilation via endoscopic retrograde cholangiopancreatography using a double-balloon endoscope for CJS between October 2010 and October 2023. The study outcomes included technical and clinical success rates, adverse event rates, choledochojejunal anastomotic stricture recurrence rates, and time to recurrence for balloon dilation and CMS treatment for CJS. RESULTS: There were 43 patients, 55 procedures (40 balloon dilation and 15 CMS placement). The technical and clinical success rates were 100% for both treatments. Recurrence of CJS was observed in 35% (14/40) of the patients in the balloon dilation group. The recurrence rate was significantly higher in the balloon dilation group than in the CMS group (35% vs. 0%, p = 0.006). The time to CJS recurrence was significantly shorter in the balloon dilation group than in the covered metallic stent group (NR vs. NR, p = 0.03). CONCLUSION: Placement of CMS for treating patients with CJS was demonstrated to be an effective and safe method with a lower recurrence rate than balloon dilation.

Implantation cyst appearing more than 30 years after gastrectomy.

Implantation cyst is often reported to be a delayed complication after colorectal surgery. This report presents a 70-year-old man undergoing gastrectomy 33 years earlier for an acute gastric ulcer. His endoscopic finding showed a submucosal tumor about 20 mm in diameter at the gastro-jejunal anastomosis. Endoscopic ultrasonography showed that the tumor was a cystic mass that was continuous from the third layer, but there were no existences of internal substantial nodules, indicating that the tumor was diagnosed as implantation cyst. This is the first report showing that implantation cyst can occur at gastro-jejunal anastomosis. We should take into account the occurrence of implantation cyst, when we encounter a submucosal tumor at gastro-jejunal anastomosis after surgery even if a long period has passed.

Vitamin D deficiency stratifies the risk of covert and overt hepatic encephalopathy in patients with cirrhosis: A retrospective cohort study.

BACKGROUNDS & AIMS: This study aimed to investigate the association between vitamin D deficiency and covert hepatic encephalopathy (CHE), overt hepatic encephalopathy (OHE) occurrence, and mortality in patients with cirrhosis. METHODS: This retrospective study reviewed 679 patients with cirrhosis. Vitamin D deficiency was defined as serum 25-hydorxyvitamin D (25-OHD) levels < 20 ng/mL. The associations between 25-OHD and CHE, OHE occurrence, and mortality were assessed using logistic regression, Fine-Gray competing risk regression, and Cox proportional hazards regression models, respectively. RESULTS: Of 428 eligible patients, 75% had vitamin D deficiency and 23% had CHE. The prevalence of CHE was higher in patients with vitamin D deficiency than in those without vitamin D deficiency (28% vs. 13%, p = 0.002). During the median follow-up period of 2.3 years, 14% of the patients developed OHE and 27% died. Patients with vitamin D deficiency had a higher incidence of OHE (p = 0.002) and mortality (p = 0.006) than those without vitamin D deficiency. After adjustment for potential covariates, multivariate analyses showed that 25-OHE was associated with CHE (odds ratio, 0.95; 95% confidence interval [CI], 0.91-0.99; p = 0.023), OHE occurrence (sub-distribution hazard ratio, 0.92; 95% CI, 0.86-0.98; p = 0.013) and mortality (hazard ratio, 0.96; 95% CI, 0.93-0.99; p = 0.020) in patients with cirrhosis. CONCLUSIONS: Vitamin D deficiency is highly prevalent and is associated with CHE, OHE, and mortality in patients with cirrhosis. Evaluation of vitamin D is essential to predict the outcomes of patients with cirrhosis.

Acute kidney injury development is associated with mortality in Japanese patients with cirrhosis: impact of amino acid imbalance.

BACKGROUND: Acute kidney injury (AKI) is a serious complication of cirrhosis. This study analyzed the prognostic effect of AKI in patients with cirrhosis and its risk factors, particularly in relation to amino acid imbalance. METHODS: This retrospective study reviewed 808 inpatients with cirrhosis at two institutes in Gifu, Japan. AKI was diagnosed according to the recommendations of the International Club of Ascites. Amino acid imbalance was assessed by measuring serum branched-chain amino acid (BCAA) levels, tyrosine levels, and the BCAA-to-tyrosine ratio (BTR). Factors associated with mortality and AKI development were assessed using the Cox proportional hazards regression model with AKI as a time-dependent covariate and the Fine-Gray competing risk regression model, respectively. RESULTS: Of the 567 eligible patients without AKI at baseline, 27% developed AKI and 25% died during a median follow-up period of 4.7 years. Using a time-dependent covariate, AKI development (hazard ratio [HR], 6.25; 95% confidence interval [CI], 3.98-9.80; p < 0.001) was associated with mortality in patients with cirrhosis independent of potential covariates. In addition, alcohol-associated/-related liver disease, metabolic dysfunction-associated steatohepatitis, Child-Pugh score, and BTR (subdistribution HR 0.78; 95% CI 0.63-0.96; p = 0.022) were independently associated with AKI development in patients with cirrhosis. Similar results were obtained in the multivariate model that included BCAA and tyrosine levels instead of BTR. CONCLUSIONS: AKI is common and associated with mortality in Japanese patients with cirrhosis. An amino acid imbalance is strongly associated with the development of AKI in patients with cirrhosis.

Usefulness of health checkup-based indices in identifying metabolic dysfunction-associated steatotic liver disease.

Aims: The application of indices in the context of metabolic dysfunction-associated steatotic liver disease (MASLD) remains unexplored. We aimed to validate the ability of alanine aminotransferase (ALT), fatty liver index (FLI), and hepatic steatosis index (HSI) to identify MASLD during health checkups. Methods: We recruited 627 participants and utilized their health checkup data and ultrasound to assess the potential of using ALT, FLI, and HSI as indices for MASLD; this was indicated by the area under the curve (AUC) and restricted cubic spline (RCS) model. The optimal, rule-out (sensitivity ≥90%), and rule-in (specificity ≥90%) cutoff values of each index for identifying MASLD were reported. Results: Among participants with a median age of 46 years, the prevalence of MASLD was 28% in total (38% in males and 18% in females). RCS models confirmed a linear association between indices and MASLD. ROC analyses indicated that the AUC of ALT in identifying MASLD was 0.79 for the total cohort, 0.81 for males, and 0.69 for females. The optimal, rule-out, and rule-in cutoff values for ALT were 21, 13, and 29, respectively. Similarly, the AUC of FLI/HSI in identifying MASLD was 0.90/0.88 for the total cohort, 0.86/0.85 for males, and 0.93/0.90 for females. Considering the reference cutoff values, distinct cutoff values were observed between the sexes for FLI, while HSI had similar cutoff values. Conclusion: This study demonstrated that ALT > 30 IU/L is a reasonable cutoff value to rule-in MASLD. ALT, FLI, and HSI are reliable indices for identifying MASLD during health checkups.

Diagnosis of pancreatic malignancies using an overnight-stored pancreatic juice cell block specimen.

BACKGROUND AND AIMS: Pancreatic juice cytology is useful for diagnosing pancreatic duct strictures and cystic lesions. However, some cases cannot be diagnosed using cytology. This study aimed to evaluate the utility of the overnight-stored pancreatic juice cell block (CB) method for diagnosing pancreatic disease. METHODS: This retrospective study included 32 patients who presented with pancreatic duct strictures or cystic lesions between 2018 and 2024. The sensitivity, specificity, and accuracy of the CB method and single/multiple pancreatic juice cytology were compared to evaluate the utility of the CB. RESULT: An endoscopic nasopancreatic drainage tube was placed in the main pancreatic duct, and pancreatic juice was collected to create a CB specimen. The median amount of pancreatic juice collected was 180(30-200) mL, and the median number of cytological examinations was three(2-8). Of the 32 cases, 13 were malignant, and 19 were benign (non-malignant). The sensitivity was significantly higher for the CB method (62 %) than for single cytology(15 %, P = 0.0414), and there was no significant difference between CB and multiple cytology(54 %, P = 1.0). The specificity and accuracy were not significantly different between the CB method and single or multiple cytology. When multiple cytology and CB were combined, sensitivity improved to 77 %. The pathological findings of the CB specimens were similar to the surgical specimens, including immunohistochemistry. CONCLUSION: The overnight-stored pancreatic juice CB method was more effective than single cytology, with similar sensitivities to multiple cytology and can also be used for immunohistochemistry. The pancreatic juice CB method is useful for pancreatic juice assessment.

Possibility of Cell Block Specimens from Overnight-Stored Bile for Next-Generation Sequencing of Cholangiocarcinoma.

The identification of anticancer therapies using next-generation sequencing (NGS) is necessary for the treatment of cholangiocarcinoma. NGS can be easily performed when cell blocks (CB) are obtained from bile stored overnight. We compared NGS results of paired CB and surgically resected specimens (SRS) from the same cholangiocarcinoma cases. Of the prospectively collected 64 bile CBs from 2018 to 2023, NGS was performed for three cases of cholangiocarcinoma that could be compared with the SRS results. The median numbers of DNA and RNA reads were 95,077,806 [CB] vs. 93,161,788 [SRS] and 22,101,328 [CB] vs. 24,806,180 [SRS], respectively. We evaluated 588 genes and found that almost all genetic alterations were attributed to single-nucleotide variants, insertions/deletions, and multi-nucleotide variants. The coverage rate of variants in SRS by those found in CB was 97.9-99.2%, and the coverage rate of SRS genes by CB genes was 99.6-99.7%. The NGS results of CB fully covered the variants and genetic alterations observed in paired SRS samples. As bile CB is easy to prepare in general hospitals, our results suggest the potential use of bile CB as a novel method for NGS-based evaluation of cholangiocarcinoma.

A rare case of schwannoma of the small intestine discovered during intussusception.

A woman in her 60s with anemia was diagnosed with a small intestinal intussusception on computed tomography. She underwent a double-balloon endoscopy, which revealed submucosal tumor in the ileum. Suspected to be the cause of anemia and intussusception, surgical intervention was carried out, revealing it to be a schwannoma. Schwannomas of the small intestine are very rare, and because exophytic growths are common, intussusception due to luminal side development is even rarer.

Peroral Pancreatoscopy-Guided Lithotripsy Compared with Extracorporeal Shock Wave Lithotripsy in the Management of Pancreatic Duct Stones in Chronic Pancreatitis: A Multicenter Retrospective Cohort Study.

BACKGROUND: Extracorporeal shock wave lithotripsy (ESWL) is a common treatment for pancreatic stones in chronic pancreatitis. In contrast, peroral pancreatoscopy-guided lithotripsy (POPS-L) remains underexplored, with limited comparative studies to ESWL. This study compared the treatment outcomes of disposable POPS-L tools and ESWL for pancreatic stones. METHODS: A retrospective analysis was conducted on 66 patients who had undergone pancreatic stone treatment at three institutions between 2006 and 2022. The treatment outcomes of POPS-L and ESWL were compared. RESULTS: This study included 19 and 47 patients who had undergone POPS-L and ESWL, respectively. In a comparison between POPS-L and ESWL, the stone clearance rates were 78.9% vs. 70.2% (p = 0.55), while the procedure-related complication rates were 21% vs. 6.3% (p = 0.09). The median total session counts were 1 vs. 5 (p < 0.01). The cumulative stone recurrence rates were comparable in both groups. Multivariate analysis revealed no significant factors influencing the stone clearance rates, and the choice between POPS-L and ESWL did not affect the stone clearance rates. CONCLUSIONS: POPS-L and ESWL exhibited comparable treatment outcomes in terms of stone clearance, complications, and recurrence rates. Furthermore, POPS-L is advantageous due to the need for fewer sessions to achieve pancreatic stone clearance.

Real-world efficacy and safety of tofacitinib treatment in Asian patients with ulcerative colitis.

BACKGROUND: Real-world data on tofacitinib (TOF) covering a period of more than 1 year for a sufficient number of Asian patients with ulcerative colitis (UC) are scarce. AIM: To investigate the long-term efficacy and safety of TOF treatment for UC, including clinical issues. METHODS: We performed a retrospective single-center observational analysis of 111 UC patients administered TOF at Hyogo Medical University as a tertiary inflammatory bowel disease center. All consecutive UC patients who received TOF between May 2018 and February 2020 were enrolled. Patients were followed up until August 2020. The primary outcome was the clinical response rate at week 8. Secondary outcomes included clinical remission at week 8, cumulative persistence rate of TOF administration, colectomy-free survival, relapse after tapering of TOF and predictors of clinical response at week 8 and week 48. RESULTS: The clinical response and remission rates were 66.3% and 50.5% at week 8, and 47.1% and 43.5% at week 48, respectively. The overall cumulative clinical remission rate was 61.7% at week 48 and history of anti-tumor necrosis factor-alpha (TNF-α) agents use had no influence (P = 0.25). The cumulative TOF persistence rate at week 48 was significantly lower in patients without clinical remission than in those with remission at week 8 (30.9% vs 88.1%; P < 0.001). Baseline partial Mayo Score was significantly lower in responders vs non-responders at week 8 (odds ratio: 0.61, 95% confidence interval: 0.45-0.82, P = 0.001). Relapse occurred in 45.7% of patients after TOF tapering, and 85.7% of patients responded within 4 wk after re-increase. All 6 patients with herpes zoster (HZ) developed the infection after achieving remission by TOF. CONCLUSION: TOF was more effective in UC patients with mild activity at baseline and its efficacy was not affected by previous treatment with anti-TNF-α agents. Most relapsed patients responded again after re-increase of TOF and nearly half relapsed after tapering off TOF. Special attention is needed for tapering and HZ.

Medication reconciliation by pharmacists for pre-admission patients improves patient safety.

BACKGROUND: Medication errors related to the pre-admission medication history obtained on admission are a major cause of medication error during hospitalization. Medication reconciliation (MR) improves patient safety through the detection of inadvertent medication discrepancies at transitions of care. The aim of this study was to evaluate the effect of MR by pharmacists for patients prior to hospital admission on the incidence of medication errors in the early post-admission period. PATIENTS AND METHODS: Patients admitted to the orthopedic ward for surgery between April 2012 and March 2020 were included. Pharmacist-led MR for pre-admission patients was started on April 1, 2017. The incidence of medication errors related to pre-admission medications that occurred during hospitalization were compared between the pre- and post-initiation of pharmacist-led MR (pre-initiation: April 1, 2012 to March 31, 2015, post-initiation: April 1, 2017 to March 31, 2020). RESULT: In the post-initiation group, 94.2% (1245/1321) of patients who were taking medications on admission had a pharmacist-led MR before admission. The proportion of patients whose physicians ordered the prescription of their pre-admission medications at the time before hospitalization to continue from admission was significantly higher in the post-initiation group than in the pre-initiation group (47.4% vs. 1.0%, p < 0.001). The incidence of medication errors related to pre-admission medications during hospitalization was significantly lower in the post-initiation group than in the pre-initiation group (1.83% vs. 0.85%, p = 0.025). Pharmacist-led MR prior to admission was a significant protective factor against incidents related to pre-admission medication (odds ratio (OR), 0.3810; 95% confidence interval (CI); 0.156-0.9320, p = 0.035). CONCLUSION: Pharmacist-led MR for patients prior to hospital admission led to a reduction in medication errors related to pre-admission medications during hospitalization. Patient safety during hospitalization can be improved by accurate medication histories provided early by pharmacists.

Asymptomatic intestinal tuberculosis of the terminal ileum diagnosed on colonoscopy: a case report and literature review.

Objective: Colonoscopy is useful in diagnosing intestinal tuberculosis. However, the terminal ileum is generally not examined during routine colonoscopy. Therefore, even with colonoscopy, the diagnosis can be missed in patients with lesions confined to the terminal ileum. Herein, we report the case of an asymptomatic patient with intestinal tuberculosis, in whom a colonoscope insertion into the terminal ileum led to the diagnosis. Patient: An asymptomatic 71-year-old man visited our hospital for a colonoscopy after a positive fecal occult blood test. Results: Colonoscopy revealed diffuse edematous and erosive mucosa in the terminal ileum. Mycobacterium tuberculosis was detected by polymerase chain reaction and culture of biopsy specimens from the erosions, leading to the diagnosis of intestinal tuberculosis. The patient was treated with antitubercular agents for 6 months, and a follow-up colonoscopy revealed healing of the lesions. Conclusion: Asymptomatic intestinal tuberculosis may occasionally be detected on colonoscopy following a positive fecal occult blood test and is sometimes confined to the terminal ileum. Therefore, clinicians should consider intestinal tuberculosis in the differential diagnosis of the causes of positive fecal occult blood test results and perform colonoscopies, including observation of the terminal ileum.

Nutritional counseling improves mortality and prevents hepatic encephalopathy in patients with alcohol-associated liver disease.

AIM: Nutritional counseling improves malnutrition, which determines the prognosis of patients with chronic liver disease. In this study, we investigated the effects of nutritional counseling on mortality and the risk of overt hepatic encephalopathy (HE) in patients with alcohol-associated liver disease. METHODS: In this retrospective cohort study, we included 211 patients with alcohol-associated liver disease who visited Gifu University Hospital between August 2008 and June 2023. Patients were classified into two groups according to the frequency of nutritional counseling by a registered dietitian. The primary outcomes were all-cause mortality and overt HE. Propensity score matching analysis was performed to adjust for potential confounders. RESULTS: Among the patients (median age 67 years; 88% men; and median Model for End-Stage Liver Disease score, 9), 86 (39%) were in the high-frequency (≥2) nutritional counseling group. The high-frequency group had a significantly higher survival rate (46% vs. 25%) and a lower incidence of overt HE (16% vs. 27%) at 5 years than the low-frequency group. Nutritional counseling was associated with a reduced risk of mortality (hazard ratio [HR] 0.48; 95% confidence interval [CI] 0.36-0.63) and overt HE (HR 0.64; 95% CI 0.42-0.99), independent of hepatocellular carcinoma and liver function reserve. After propensity score matching, nutritional counseling was still associated with a reduced risk of mortality (HR 0.34; 95% CI 0.19-0.59) and overt HE (HR 0.31; 95% CI 0.11-0.87). CONCLUSIONS: Nutritional counseling effectively improves mortality and prevents overt HE in patients with alcohol-associated liver disease, thereby proving essential for the management of these patients.

Dysphagia risk evaluated by the Eating Assessment Tool-10 is associated with health-related quality of life in patients with chronic liver disease.

OBJECTIVE: This study aimed to reveal the prevalence and characteristics of individuals at risk of dysphagia in patients with chronic liver disease (CLD) and its association with health-related quality of life (HRQOL). METHODS: This cross-sectional study included 335 outpatients with CLD. Dysphagia risk, sarcopenia risk, malnutrition risk, and HRQOL were assessed using the Eating Assessment tool-10 (EAT-10), SARC-F, Royal Free Hospital-Nutrition Prioritizing Tool (RFH-NPT), and Chronic Liver Disease Questionnaire (CLDQ), respectively. Dysphagia risk and low HRQOL were based on EAT-10 ≥3 and CLDQ overall score <5, respectively. Factors associated with dysphagia risk and low HRQOL were assessed using the logistic regression model. RESULTS: Dysphagia risk and lower HRQOL were observed in 10% and 31% of the patients, respectively. Patients with dysphagia risk were older, had lower liver functional reserve, were at higher risk for sarcopenia and malnutrition, and showed lower CLDQ overall score (median, 4.41 vs. 5.69; P < 0.001) than those without. After adjustment, SARC-F (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.02-1.50; P = 0.029) and RFH-NPT (OR, 1.71; 95% CI, 1.04-2.81; P = 0.034) scores were independently associated with dysphagia risk. EAT-10 (OR, 1.17; 95% CI, 1.04-1.30; P = 0.008) and SARC-F (OR, 1.37; 95% CI, 1.18-1.59; P < 0.001) scores were also independently associated with low HRQOL. CONCLUSIONS: Dysphagia risk was prevalent in approximately 10% of patients with CLD and was associated with a risk of sarcopenia and malnutrition. Furthermore, dysphagia risk was related to HRQOL in patients with CLD.

Evaluating optimal bilateral biliary stenting in endoscopic reintervention after initial plastic stent dysfunction for unresectable malignant hilar biliary obstruction: Retrospective cross-sectional study.

OBJECTIVES: The placement of plastic stents (PS), including intraductal PS (IS), is useful in patients with unresectable malignant hilar biliary obstruction (UMHBO) because of patency and ease of endoscopic reintervention (ERI). However, the optimal stent replacement method for PS remains unclear. METHODS: This retrospective study included 322 patients with UMHBO. Among them, 146 received PS placement as initial drainage (across-the-papilla PS [aPS], 54; IS, 92), whereas 75 required ERI. Eight bilateral aPS, 21 bilateral IS, and 17 bilateral self-expandable metallic stent (SEMS) placements met the inclusion criteria. Rates of technical and clinical success, adverse events, recurrent biliary obstruction (RBO), time to RBO (TRBO), overall survival, and secondary ERI were compared. RESULTS: There were no significant intergroup differences in rates of technical or clinical success, adverse events, RBO occurrence, or overall survival. The median TRBO was significantly shorter in the aPS group (47 days) than IS (91 days; P = 0.0196) and SEMS (143 days; P < 0.01) groups. Median TRBO did not differ significantly between the IS and SEMS groups (P = 0.44). On Cox multivariate analysis, the aPS group had the shortest stent patency (hazard ratio 2.67 [95% confidence interval 1.05-6.76], P = 0.038). For secondary ERI, the median endoscopic procedure time was significantly shorter in the IS (22 min) vs. SEMS (40 min) group (P = 0.034). CONCLUSIONS: Bilateral IS and SEMS placement featured prolonged patency after first ERI. Because bilateral IS placement is faster than SEMS placement and IS can be removed during secondary ERI, it may be a good option for first ERI.

Impact of Skeletal Muscle Depletion on Patients with Myelodysplastic Syndrome Treated with Azacitidine.

BACKGROUND: Azacitidine (AZA) is the standard treatment for patients with high-risk myelodysplastic syndromes (MDS). The impact of skeletal muscle depletion (SMD), which is associated with outcomes of hematological malignancies, on the clinical course of MDS patients treated with AZA was investigated. METHODS: This retrospective, observational study included 50 MDS patients treated with AZA. Muscle mass was evaluated using the skeletal muscle index (SMI), which is the area of muscle mass at the third lumbar vertebra on CT images divided by the square of the height. RESULTS: Of the enrolled patients, 39 were males, and their median age was 69.5 years. Twenty-seven (20 male and 7 female) patients showed SMD. The median survival was 13.4 months in the SMD group and 15.2 months in the non-SMD group, with no significant difference and no significant association between the response rate or severe non-hematological toxicities and the presence of SMD. By contrast, grade 3-4 anemia and thrombocytopenia were significantly more frequent in the SMD group than in the non-SMD group. SMD was associated with severe anemia and thrombocytopenia in MDS patients treated with AZA. CONCLUSION: Reduced skeletal muscle mass may predict severe hematological toxicity in MDS patients treated with AZA.

A Case of Unresectable Combined Hepatocellular-cholangiocarcinoma Treated with Combination Therapy Consisting of Durvalumab Plus Tremelimumab.

Combined hepatocellular cholangiocarcinoma is a rare and challenging primary liver malignancy that lacks any established standard treatments for unresectable cases. We herein present the first known case of a 49-year-old woman diagnosed with unresectable combined hepatocellular-cholangiocarcinoma, who underwent novel chemotherapy involving durvalumab plus tremelimumab combination therapy. The treatment was temporarily discontinued owing to immune-related adverse events, such as rash, and the patient was subsequently managed with systemic steroid therapy; however, the disease progressed after two courses of this treatment. Further studies are needed to validate the efficacy and safety of immune checkpoint inhibitors such as durvalumab and tremelimumab for the treatment of unresectable combined hepatocellular cholangiocarcinoma.

Advances and efficacy in specimen handling for endoscopic ultrasound-guided fine needle aspiration and biopsy: A comprehensive review.

Endoscopic ultrasound-guided fine needle aspiration and biopsy have significantly evolved since they offer a minimally invasive approach for obtaining pathological specimens from lesions adjacent to or within the intestine. This paper reviews advancements in endoscopic ultrasound-guided fine needle aspiration and biopsy techniques and devices, emphasizing the importance of handling specimens for diagnostic accuracy. Innovations of fine needle biopsy needles with features like side holes and Franseen shapes have enhanced histological sampling capabilities. Techniques for specimen handling, including rapid on-site evaluation and macroscopic on-site evaluation, play pivotal roles in assessing sample adequacy, thereby influencing diagnostic outcomes. The utility of artificial intelligence in augmenting rapid on-site evaluation and macroscopic on-site evaluation, although still in experimental stages, presents a promising avenue for improving procedural efficiency and diagnostic precision. The choice of specimen handling technique is dependent on various factors including endoscopist preference, procedure objectives, and available resources, underscoring the need for a comprehensive understanding of each method's characteristics to optimize diagnostic efficacy and procedural safety.
