Impact of biliary stents in the performance of the EUS-guided tissue acquisition: A systematic review and meta-analysis / Impacto de los stents biliares en el rendimiento de la adquisición de biopsias guiadas por ecoendoscopia: una revisión sistemática y metanálisis

Introduction and aim: Pancreatobiliary tumours are challenging to diagnose exclusively by imaging methods. Although the optimum moment for carrying out the EUS is not well defined, it has been suggested that the presence of biliary stents may interfere with the proper staging of tumours and the acquisition of samples. We performed a meta-analysis to evaluate the impact of biliary stents on EUS-guided tissue acquisition yield. Material and methods: We conducted a systematic review in different databases, such as PubMed, Cochrane, Medline, and OVID Database. A search was made of all studies published up to February 2022. Results: Eight studies were analyzed. A total of 3185 patients were included. The mean age was 66.9±2.7 years; 55.4% were male gender. Overall, 1761 patients (55.3%) underwent EUS guided tissue acquisition (EUS-TA) with stents in situ, whereas 1424 patients (44.7%) underwent EUS-TA without stents. The technical success was similar in both groups (EUS-TA with stents: 88% vs EUS-TA without stents: 88%, OR=0.92 [95% CI 0.55–1.56]). The type of stent, the needle size and the number of the passes were similar in both groups. Conclusions: EUS-TA has similar diagnostic performance and technical success in patients with or without stents. The type of stent (SEMS or plastic) does not seem to influence the diagnostic performance of EUS-TA. Future prospectives and RCT studies are needed to strengthen these conclusions. (AU)

Introducción y objetivo: Los tumores pancreatobiliares son lesiones difíciles de diagnosticar exclusivamente por métodos de imagen. Aunque no está bien definido el momento óptimo para la realización de la ecoendoscopia (EUS), se ha demostrado que la presencia de stents biliares puede interferir en la correcta estadificación de los tumores y la toma de muestras. Realizamos un metanálisis para evaluar el impacto de los stents biliares en el rendimiento de la adquisición de tejido guiada por EUS. Material y métodos: Realizamos una revisión sistemática en diferentes bases de datos, como PubMed, Cochrane, Medline y OVID Database. Se realizó una búsqueda de todos los estudios publicados hasta febrero de 2022. Resultados: Se analizaron 8 estudios. Se incluyeron un total de 3.185 pacientes. La media de edad fue de 66,9±2,7 años; el 55,4% fueron pacientes de sexo masculino. En total, 1.761 pacientes (55,3%) se sometieron a biopsias guiadas por EUS con stents in situ, mientras que 1.424 pacientes (44,7%) se sometieron a dichas biopsias sin stents. El éxito técnico fue similar en ambos grupos (EUS con stents: 88% vs. EUS sin stents: 88%, OR=0,92 [IC 95% 0,55-1,56]). El tipo de stent, el tamaño de la aguja y el número de pases fueron similares en ambos grupos. Conclusiones: La biopsia por EUS tiene un rendimiento diagnóstico y un éxito técnico similares en pacientes con o sin stents. El tipo de stent (SEMS o plástico) no parece influir en el rendimiento diagnóstico de la adquisición de tejido guiada por EUS. Se necesitan futuros estudios prospectivos y estudios aleatorizados controlados para fortalecer estas conclusiones. (AU)

Survey on initial management of acute pancreatitis in Latin America / Encuesta sobre el manejo inicial de la pancreatitis aguda en América Latina

Objective: The population of Latin America harbors the highest incidence of gallstones and acute biliary pancreatitis, yet little is known about the initial management of acute pancreatitis in this large geographic region. Participants and methods: We performed a post hoc analysis of responses from physicians based in Latin America to the international multidisciplinary survey on the initial management of acute pancreatitis. The questionnaire asked about management of patients during the first 72h after admission, related to fluid therapy, prescription of prophylactic antibiotics, feeding and nutrition, and timing of cholecystectomy. Adherence to clinical guidelines in this region was compared with the rest of the world. Results: The survey was completed by 358 participants from 19 Latin American countries (median age, 39 years [33–47]; women, 27.1%). The proportion of participants in Latin America vs. the rest of the world who chose non-compliant options with clinical guidelines were: prescription of fluid therapy rate other than moderate (42.2% vs 34.3%, P=.02); prescription of prophylactic antibiotics for severe (10.6% vs 18.0%, P=.002), necrotizing (28.5% vs 36.9%, P=.008), or systemic inflammatory response syndrome-associated (21.2% vs 30.6%, P=.002) acute pancreatitis; not starting an oral diet to patients with oral tolerance (77.9% vs 71.1%, P=.02); and delayed cholecystectomy (16.2% vs 33.8%, P<.001). Conclusions: Surveyed physicians in Latin America are less likely to prescribe antibiotics and to delay cholecystectomy when managing patients in the initial phase of acute pancreatitis compared to physicians in the rest of the world. Feeding and nutrition appear to require the greatest improvement. (AU)

Objetivo: La población de América Latina alberga la mayor incidencia de cálculos biliares y pancreatitis biliar aguda, sin embargo, poco se sabe sobre el manejo inicial de la pancreatitis aguda en esta extensa región geográfica. Participantes y métodos: Se realizó un análisis post hoc de las respuestas de los médicos de América Latina a la encuesta internacional multidisciplinar sobre el tratamiento inicial de la pancreatitis aguda. En el cuestionario se preguntaba por el manejo de los pacientes durante las primeras 72 h tras el ingreso, en relación con la fluidoterapia, la prescripción de antibióticos profilácticos, la alimentación y nutrición y el momento de la colecistectomía. La adherencia a las guías clínicas en esta región se comparó con la del resto del mundo. Resultados: La encuesta fue completada por 358 participantes de 19 países latinoamericanos (mediana de edad, 39 años [33-47]; mujeres, 27,1%). La proporción de participantes de América Latina frente al resto del mundo que eligieron opciones no conformes con las guías clínicas fueron: prescripción de fluidoterapia en casos distintos de los moderados (42,2 vs. 34,3%, p = 0,02); prescripción de antibióticos profilácticos en casos graves (10,6 vs. 18%, p = 0,002); necrotizante (28,5 vs. 36,9%, p = 0,008) o asociada al síndrome de respuesta inflamatoria sistémica (21,2 vs. 30,6%, p = 0,002); no inicio de dieta oral en pacientes con tolerancia oral (77,9 vs. 71,1%, p = 0,02); y retraso de la colecistectomía (16,2 vs. 33,8%, p < 0,001). Conclusiones: Los médicos encuestados en América Latina son menos propensos a prescribir antibióticos y a retrasar la colecistectomía cuando tratan a pacientes en la fase inicial de la pancreatitis aguda, en comparación con los médicos del resto del mundo. La alimentación y la nutrición parecen requerir las mayores mejoras. (AU)

Pancreatoduodenectomía laparoscópica híbrida: resultado en paciente obeso con adenocarcinoma duodenal

La cirugía pancreática mínimamente invasiva sigue ampliando sus indicaciones de manera lenta pero constante. Su aplicación en pacientes obesos y/o con neoplasias periampulares es controversial por la elevada tasa de complicaciones reportada en esta población. Presentamos un paciente de sexo masculino de 62 años, obeso (IMC 35,4 Kg/m2), hipertenso y diabético que desarrolla anemia severa (Hb = 4,9 g/dl) por adenocarcinoma de segunda porción duodenal. El estadiaje por imágenes verifica enfermedad localizada. El paciente fue sometido a pancreatoduodenectomia híbrida (resección laparoscópica/reconstrucción abierta por minilaparotomía). Se describe técnica operatoria y evolución postoperatoria. El paciente cursó sin complicaciones mayores (pancreatitis aguda moderada), el tiempo operatorio fue 540 minutos, el volumen de sangrado 400 ml, requirió la transfusión de 1 unidad de paquete globular y estancia de 8 días. No tuvo intercurrencias durante 90 días después de la cirugía. Se concluye que la pancreatoduodenectomía híbrida es una alternativa factible y segura en pacientes obesos con adenocarcinoma duodenal, ofrece ventajas en la reducción del trauma quirúrgico.

Minimally invasive pancreatic surgery has expanded slowly but steadily. The application of this approach in obese patients and/or with periampullary neoplasms is still controversial because of the high complication rate in this group of patients. We present the case of a 62-year-old male, obese (BMI 35.4 Kg/m2), hypertensive and diabetic, who developed severe anemia (Hb 4.9 g/dl) due to duodenal adenocarcinoma. Imaging staging verified localized disease. The patient underwent Hybrid Pancreatoduodenectomy (laparoscopic resection/open minilaparotomy reconstruction). The operative technique and postoperative course are described. The patient had no major complications (moderate acute pancreatitis), the operative time was 540 minutes, the bleeding volume was 400 ml, he required transfusion of 1 unit of globular package and a stay of 8 days. He had no intercurrences during 90 days after surgery. It is concluded that hybrid pancreatoduodenectomy is a feasible and safe alternative in obese patients with duodenal adenocarcinoma, offering advantages in reducing surgical trauma.

EUS-Guided gallbladder drainage vs percutaneous transhepatic drainage in patients with acute cholecystitis: a systematic review and meta-analysis

Occasionally, cholecystectomy is not possible because the patient is not suitable for surgery, and non-operative management should be performed. In these patients, the non-operative management can be through the percutaneous transhepatic gallbladder drainage (PTGBD) or the endoscopic gallbladder drainage. We decided to compare the efficacy and safety of PTGBD and EUS-GBD in the non-operative management of patients with acute cholecystitis. We conducted a systematic review in different databases, such as PubMed, OVID, Medline, and Cochrane Databases. This meta-analysis considers studies published until September 2021. Six studies were selected (2 RCTs). These studies included 749 patients. The mean age was 72.81 ±7.41 years, and males represented 57.4%. EUS-GBD technical success was lower than PTGBD (RR, 0.97; 95% CI, 0.95-0.99), whereas clinical success and adverse events rates were similar in both groups. Twenty-one deaths were reported in all six studies. The global mortality rate was 2.80%, without differences in both groups (2.84% and 2.77% in the EUS-GBD group and the PTGBD groups, respectively). EUS-GBD and PTGBD were successful techniques for gallbladder drainage in patients with acute cholecystitis who are non-tributary for surgery. EUS-GBD has a similar clinical success rate and a similar adverse events rate in comparison to PTGBD. The high technical success and the low adverse events rate of the EUS approach to gallbladder make this technique an excellent alternative for patients with acute cholecystitis who cannot be undergoing surgery.

En ocasiones, no es posible realizar una colecistectomía debido a que el paciente no es apto para la cirugía, y se debe optar por un manejo no quirúrgico. En estos pacientes, el manejo no quirúrgico puede ser a través del drenaje transhepático percutáneo de la vesícula o bien el drenaje ecoendoscópico de la misma. En el presente trabajo decidimos comparar la eficacia y seguridad de ambas técnicas en el manejo no quirúrgico de pacientes con colecistitis aguda. Métodos: Se realizó una revisión sistemática en diferentes bases de datos, como PubMed, OVID, Medline y Cochrane Databases. Este metanálisis considera estudios publicados hasta septiembre de 2021. Se seleccionaron seis estudios (2 estudios aleatorizados controlados). Estos estudios incluyeron 749 pacientes. La edad media fue de 72,81 ± 7,41 años, y los varones representaron el 57,4%. El éxito técnico del drenaje ecoendoscópico fue menor que el del drenaje percutáneo (RR, 0,97; IC del 95 %, 0,95-0,99), mientras que las tasas de éxito clínico y de eventos adversos fueron similares en ambos grupos. Se reportaron 21 muertes en los seis estudios. La tasa de mortalidad global fue del 2,80%, sin diferencias en ambos grupos (2,84% y 2,77% en el grupo ecoendoscópico y en el percutáneo, respectivamente). El drenaje ecoendoscópico y el drenaje percutáneo fueron técnicas exitosas para el drenaje de la vesícula biliar en pacientes con colecistitis aguda que no son tributarios de cirugía. El drenaje ecoendoscópico tiene una tasa de éxito clínico similar y una tasa de eventos adversos similar al drenaje percutáneo. El alto éxito técnico y la baja tasa de eventos adversos del abordaje ecoendoscópico de la vesícula biliar hacen de esta técnica una excelente alternativa para pacientes con colecistitis aguda que no pueden ser intervenidos quirúrgicamente.

Intracystic Glucose Levels Appear Useful for Diagnosis of Pancreatic Cystic Lesions: A Systematic Review and Meta-Analysis.

BACKGROUND: Carcinoembryonic antigen (CEA) in the pancreatic cystic fluid is the most important biomarker for differentiating mucinous from non-mucinous pancreatic cystic lesions (PCLs). However, recent studies have shown that glucose levels in pancreatic cystic fluid can discriminate mucinous from non-mucinous cysts. AIMS: To perform a meta-analysis to determine the utility of intracystic fluid glucose of pancreatic mucinous cysts compared with intracystic CEA. METHODS: We conducted a systematic review of the literature in the PubMed, OVID Medline, and Cochrane databases. This meta-analysis considers studies published up to October 2020. RESULTS: Six studies comprising 506 patients were selected; 61.2% of the population was female. Of the 480 PCLs, 287 (59.7%) were mucinous. Pooled sensitivity and specificity of cystic fluid glucose levels for mucinous PCLs were 91% and 85%, respectively. The positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were 6.33 and 0.11, respectively. Pooled diagnostic odds ratio (DOR) was 60.94. The pooled area under the summary receiver operating characteristic (SROC) curve was 0.959. Pooled sensitivity and specificity of pancreatic cystic fluid CEA levels were 61% and 93%. The PLR and NLR were 8.51 and 0.40, respectively. Pooled DOR was 23.52, and the pooled area under the SROC curve was 0.861. CONCLUSION: Glucose has become a useful method and appears to be better than CEA for differentiating between mucinous PCLs and non-mucinous PCLs. We suggest that the analysis of glucose in PCLs be routinely performed for the differential diagnosis of these lesions.

Head-to-head comparison between endoscopic ultrasound guided lumen apposing metal stent and plastic stents for the treatment of pancreatic fluid collections: A systematic review and meta-analysis.

BACKGROUND/AIMS: Peripancreatic fluid collections (PFCs) result from acute or chronic pancreatic inflammation that suffers a rupture of its ducts. Currently, there exists three options for drainage or debridement of pancreatic pseudocysts and walled-off necrosis (WON). The traditional procedure is drainage by placing double pigtail plastic stents (DPPS); lumen-apposing metal stent (LAMS) has a biflanged design with a wide lumen that avoids occlusion with necrotic tissue, which is more common with DPPS and reduces the possibility of migration. We performed a systematic review and meta-analyses head-to-head, including only studies that compare the two main techniques to drainage of PFCs: LAMS vs DPPS. METHODS: We conducted a systematic review in different databases, such as PubMed, OVID, Medline, and Cochrane Databases. This meta-analysis considers studies published from 2014 to 2020, including only studies that compare the two main techniques to drainage of PFCs: LAMS vs DPPS. RESULTS: Thirteen studies were included in the meta-analyses. Only one of all studies was a randomized controlled trial. These studies comprise 1584 patients; 68.2% were male, and 31.8% were female. Six hundred sixty-three patients (41.9%) were treated with LAMS, and 921 (58.1%) were treated with DPPS. Six studies included only WON in their analysis, two included only pancreatic pseudocysts, and five studies included both pancreatic pseudocysts and WON. The technical success was similar in patients treated with LAMS and DPPS (97.6% vs 97.5%, respectively, P = .986, RR = 1.00 [95% CI 0.93-1.08]). The clinical success was similar in both groups (LAMS: 90.1% vs DPPS: 84.2%, P = .139, RR = 1.063 [95% CI 0.98-1.15]). Patients treated with LAMS had a lower complication rate than the DPPS groups, with a significant statistical difference (LAMS: 16.0% vs DPPS: 20.2%, P = .009, RR = 0.746 [95% CI 0.60-0.93]). Bleeding was the most common complication in the LAMS group (33 patients, [5.0%]), whereas infection was the most common complication in the DPPS group (56 patients, [6.1%]). The LAMS migration rate was lower than in the DPPS (0.9% vs 2.2%, respectively, P = .05). The mortality rate was similar in both groups, 0.6% in the LAMS group (four patients) and 0.4% in the DPPS group (four patients; P = .640). CONCLUSION: The PFCs drainage is an indication when persistent symptoms or PFCs-related complications exist. EUS guided drainage with LAMS has similar technical and clinical success to DPPS drainage for the management of PFCs. The technical and clinical success rates are high in both groups. However, LAMS drainage has a lower adverse events rate than DPPS drainage. More randomized controlled trials are needed to confirm the real advantage of LAMS drainage over DPPS drainage.

Lactate Ringer's Versus Normal Saline in the Management of Acute Pancreatitis: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Fluid therapy plays a critical role in the management of acute pancreatitis. Normal saline (NS) is commonly used in these patients. However, Lactate Ringer's (LR) has also been shown to be useful for this condition. AIM: To assess the effect of LR compared to NS in patients with acute pancreatitis. METHODS: We searched in three electronic databases from inception to December 2020 for randomized controlled trials (RCTs). Outcomes were mortality, intensive care unit (ICU) admission, hospital stay, and Systemic Inflammatory Response Syndrome (SIRS) at 24, 48, and 72 h. The risk of bias was assessed using the Risk of Bias 2.0 tool. All meta-analyses were performed using a random-effects model. RESULTS: Four RCTs comprising 248 patients were included. The mean age ranged from 42.3 to 63.8 years and 49% of patients were men. Patients treated with LR had similar risk of mortality (risk ratio [RR], 0.53; 95% confidence interval [CI], 0.09-3.00) and SIRS at 24 h (RR, 0.69; 95% CI, 0.32-1.51), 48 h (RR, 0.80; 95% CI, 0.46-1.41), and 72 h (RR, 0.68; 95% CI, 0.37-1.25) compared to NS. LR had significantly lower hospital stay (mean difference, - 1.10; 95% CI, - 1.92 to - 0.28) and lower risk of ICU admission (RR, 0.42; 95% CI, 0.20-0.89) compared to NS. The risk of bias was low in nearly all RCTs. CONCLUSION: No differences were found in the mortality and SIRS at 24, 48, and 72 h in patients treated with LR and NS. In contrast, patients who received LR had a lower risk of ICU admission and lower hospital stay than NS.

Transpancreatic precut papillotomy versus double-guidewire technique in difficult biliary cannulation: a systematic review and meta-analysis.

Background and study aims Approximately 11 % of biliary cannulations are considered difficult. The double guidewire (DGW-T) and transpancreatic sphincterotomy (TPS) are two useful techniques when difficult cannulation exists and the main pancreatic duct is unintentionally accessed. We carried out a systematic review and meta-analysis to evaluate the effectiveness and security of both DGW-T and TPS techniques in difficult biliary cannulation. Methods We conducted a systematic review in different databases, such as PubMed, OVID, Medline, and Cochrane Databases. Were included all RCT which showed a comparison between TPS and DGW in difficult biliary cannulation. Endpoints computed were successful cannulation rate, median cannulation time, and adverse events rate. Results Four studies were selected (4 RCTs). These studies included 260 patients. The mean age was 64.79 ±â€Š12.99 years. Of the patients, 53.6 % were men and 46.4 % were women. The rate of successful cannulation was 93.3 % in the TPS group and 79.4 % in the DGW-T group ( P  = 0.420). The rate of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) was lower in patients who had undergone TPS than DGW-T (TPS: 8.9 % vs DGW-T: 22.2 %, P  = 0.02). The mean cannulation time was 14.7 ±â€Š9.4 min in the TPS group and 15.1 ±â€Š7.4 min with DGW-T ( P  = 0.349). Conclusions TPS and DGW are two useful techniques in patients with difficult cannulation. They both have a high rate of successful cannulation; however, the PEP was higher with DGW-T than with TPS.

Per-oral pancreatoscopy-guided lithotripsy for the endoscopic management of pancreatolithiasis: A systematic review and meta-analysis.

OBJECTIVE: Pancreatic stones result from chronic pancreatitis and can occur in the main pancreatic duct, pancreatic branches or parenchyma. Although extracorporeal shock wave lithotripsy (ESWL) is considered the first-line treatment, per-oral pancreatoscopy (POP) has emerged as a useful method for treating pancreatic stones. The aim of this systematic review and meta-analysis was to determine the efficacy and safety of POP-guided lithotripsy, electrohydraulic lithotripsy (EHL) and laser lithotripsy (LL), in patients with pancreatolithiasis. METHODS: Literature review was conducted in PubMed, OVID, MEDLINE and Cochrane Library databases for studies published up to August 2020. RESULTS: Altogether 15 studies were analyzed, of which 11 were retrospective and four were prospective. The studies comprised 370 patients, of whom 66.4% were male. The patients underwent 218 EHL and 155 LL. The pooled technical and clinical success rate of the overall POP was 88.1% and 87.1%. For EHL-POP, the pooled technical success rate was 90.9% (95% CI 87.2%-95.2%) and the pooled clinical success rate was 89.8% (95% CI 87.2%-95.2%). While for LL-POP, the pooled technical and clinical success rate was 88.4% (95% CI 85.9%-95.1%) and 85.8% (95% CI 80.6%-91.6%). In total 43 adverse events occurred (12.1%; 95% CI 8.7%-15.5%). CONCLUSION: POP-guided lithotripsy has a high rate of technical and clinical success for managing pancreatolithiasis with a low complication rate. Both EHL-POP and LL-POP achieve similar efficacy in the endoscopic therapy of pancreatolithiasis. Further large randomized controlled trials are needed to compare EHL-POP and LL-POP with ESWL and evaluate whether POP may replace ESWL as the first-line management of pancreatolithiasis.

Complete extraction of a long hepatic hydatid cyst with endoscopic retrograde cholangiography.

Hydatid disease or echinococcosis is a systemic zoonosis caused by Echinococcus granulosus larvae. We report the case of a 63 year-old Peruvian female patient who presented with diffuse abdominal pain and jaundice. An abdominal computed tomography (CT) scan was performed that showed a large hepatic hydatid cyst (6 x 6 cm) in segment IV with an apparent communication with the biliary duct. Laboratory results showed hemoglobin 13.2 g/dl, white blood cell (WBC) count 10,600 cell/mm3, normal serum amylase and lipase, total bilirubin 7,5 mg/dl, direct bilirubin 6,2 mg/dl and alkaline phosphatase 234 UI/l. Magnetic resonance cholangiopancreatography (MRCP) showed the same findings of the CT scan plus dilation of the biliary duct.

Endoscopic ultrasound-guided, through-the-needle forceps biopsy for diagnosis of pancreatic cystic lesions: a systematic review.

Background and study aims Pancreatic cystic lesions (PCL), are a heterogeneous group of cystic lesions. Some patients with PCLs have a significantly higher overall risk of pancreatic cancer and the only test that can differentiate benign and malignnat PCL is fine-needle aspiration plus cytological analysis, but its sensitivity is very low. Through-the-needle direct intracystic biopsy is a technique that allows acquisition of targeted tissue from PCLs and it may improve the diagnostic yield for them. The aim of this study was to review articles about endoscopic ultrasound (EUS)-guided through-the-needle intracystic biopsy for targeted tissue acquisition and diagnosis of PCLs. Methods A systematic review of computerized bibliographic databases was carried out for studies of EUS-guided through-the-needle forceps biopsy (EUS-TTNB) of PCLs. The percentages and their 95 % confidence intervals (CIs) were calculated for all the considered endpoints (technical success, adequate specimens, adverse events (AEs), and overall diagnosis). Results Overall, eight studies with a total of 423 patients were identified. Pooled technical success was 95.6 % of the cases (399/423), (95 % CI, 93.2 %-97.3 %). Technical failure rate was 5.1 % (24 cases). Frequency of adequate specimens was 82.2 %, (95 % CI, 78.5 %-85.8 %). Adverse events were reported in seven of the eight studies. Forty-two total adverse events were reported (10.1 %) (95 % CI, 7.3 %-13.6 %). The overall ability to provide a specific diagnosis with EUS-TTNB for diagnosis of pancreatic cystic lesions was 74.6 % (313 cases), (95 % CI: 70.2 %-78.7 %). The most frequent diagnoses found with EUS-TTNB were mucinous cystic neoplasms (MCN) in 96 cases (30.6 %), IPMN in 80 cases (25.5 %), and serous cystoadenoma neoplasm (SCN) in 48 cases (15.3 %). Conclusions Through-the-needle forceps biopsy appears to be effective and safe, with few AE for diagnosis of pancreatic cystic lesions. This technique had acceptable rates of technical and clinical success and an excellent safety profile. TTNB is associated with a high tissue acquisition yield and provided additional diagnostic yield for mucinous pancreatic lesions. TTNB may be a useful adjunctive tool for EUS-guided assessment of PCLs.
