RESUMO
BACKGROUND: Viral infections are known to impact the pancreato-biliary system; however, there are limited data showing that the same is true of COVID-19. Endoscopic retrograde cholangiopancreatography (ERCP) can safely be performed in patients with COVID-19 infection, but outcomes of patients with COVID-19 infections and concomitant pancreatic and biliary disease requiring endoscopic intervention are unknown. AIMS: This study aims to evaluate the severity of pancreaticobiliary diseases and post-ERCP outcomes in COVID-19 patients. METHODS: Patients with pancreato-biliary disease that required inpatient ERCP from five centers in the United States and South America between January 1, 2020, and October 31, 2020 were included. A representative cohort of patients from each month were randomly selected from each site. Disease severity and post-ERCP outcomes were compared between COVID-19 positive and COVID-19 negative patients. RESULTS: A total of 175 patients were included: 95 COVID positive and 80 COVID negative. Mean CTSI score for the patients who had pancreatitis was higher in COVID-positive cohort by 3.2 points (p < .00001). The COVID-positive group had more cases with severe disease (n = 41) versus the COVID-negative group (n = 2) (p < .00001). Mortality was higher in the COVID-19 positive group (19%) compared to COVID-negative group (7.5%) even though the COVID-19-negative group had higher incidence of malignancy (n = 17, 21% vs n = 7, 7.3%) (p = 0.0455). CONCLUSIONS: This study shows that patients with COVID infection have more severe pancreato-biliary disease and worse post-ERCP outcomes, including longer length of stay and higher mortality rate. These are important considerations when planning for endoscopic intervention. CLINICALTRIALS: gov: (NCT05051358).
RESUMO
We describe a case of a gastric neuroendocrine tumor (NET) in a patient with a history of long- term proton pump inhibitor (PPI) use. A 29- year- old man using PPI for the last 10 years due to gastroesophageal reflux disease developed progressive bouts of heartburn. Upper gastrointestinal endoscopy localized an elevated lesion with central depression in the greater curvature of gastric body. Lesion biopsies revealed a well- differentiated neuroendocrine tumor. Despite PPIs have a well- established safety profile, concerns have been raised about a potential relationship between PPI- induced hypergastrinemia and the development of neuroendocrine tumors.

BACKGROUND AND AIMS: Digital single-operator cholangioscopy (DSOC) allows direct visualization of the biliary tree for evaluation of biliary strictures. Our objective was to assess the interobserver agreement (IOA) of DSOC interpretation for indeterminate biliary strictures using newly refined criteria. METHODS: Fourteen endoscopists were asked to review an atlas of reference clips and images of 5 criteria derived from expert consensus. They then proceeded to score 50 deidentified DSOC video clips based on the visualization of tortuous and dilated vessels, irregular nodulations, raised intraductal lesions, irregular surface with or without ulcerations, and friability. The endoscopists then diagnosed the clips as neoplastic or non-neoplastic. Intraclass correlation (ICC) analysis was done to evaluate inter-rater agreement for both criteria sets and final diagnosis. RESULTS: Clips of 41 malignant lesions and 9 benign lesions were scored. Three of 5 revised criteria had almost perfect agreement. ICC was almost perfect for presence of tortuous and dilated vessels (.86), raised intraductal lesions (.90), and presence of friability (.83); substantial agreement for presence of irregular nodulations (.71); and moderate agreement for presence of irregular surface with or without ulcerations (.44). The diagnostic ICC was almost perfect for neoplastic (.90) and non-neoplastic (.90) diagnoses. The overall diagnostic accuracy using the revised criteria was 77%, ranging from 64% to 88%. CONCLUSIONS: The IOA and accuracy rate of DSOC using the new Mendoza criteria shows a significant increase of 16% and 20% compared with previous criteria. The reference atlas helps with formal training and may improve diagnostic accuracy. (Clinical trial registration number: NCT02166099.).

INTRODUCTION: Preoperative diagnostic imaging of pancreatic solid pseudopapillary neoplasms (SPNs) is challenging. A few studies have investigated the role of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for the diagnosis of SPN. We investigated the diagnostic yield of cell-blocks and immunohistochemistry (IHC) for SPN using EUS-FNA specimens without cytological evaluation. PATIENTS AND METHODS: We retrospectively analysed the histopathology records of patients with suspected SPN, who underwent EUS-FNA biopsy between January 1997 and January 2020. Diagnosis based on cell-blocks (haematoxylin-eosin staining with complementary IHC) was compared with the definitive surgical diagnosis. RESULTS: This study included 25 patients (24 were women). Patients' mean age was 33.7 years (range 12-78 years). The most common symptom was abdominal pain. SPN was an incidental finding in 52% of the patients. The mean lesion size was 4.3 cm (range 1.2-11.4 cm), and the most common endosonographic features included solid-cystic (56%) or solid (40%) tumours. Final diagnoses included SPNs (n = 23) and non-functioning neuroendocrine tumours (n = 2). The overall accuracy of EUS-FNA was 80%. Tumour cells showed immunopositivity for ß-catenin, CD10, CD99 and progesterone receptor (PR) in 93.7%, 87.5%, 83.3% and 66.6% of patients, respectively. No SPN showed immunopositivity for chromogranin A. CONCLUSIONS: Intention-to-diagnose analysis showed that the diagnostic accuracy of EUS-FNA for SPNs using cell blocks and complementary IHC without cytological evaluation was fairly good. Evaluation of ß-catenin, CD 10, CD99 and PR expression must be included in the IHC panel for diagnostic confirmation of SPNs using EUS-FNA biopsy specimens.

BACKGROUND AND AIMS: Escalating an indication of EUS for diagnosis and treatment justifies the evaluation of the conditions associated with the adverse events (AE) and related deaths. The aim is to evaluate and compare the incidence of AE and deaths after diagnostic-EUS (D-EUS) and interventional-EUS (I-EUS). METHODS: This retrospective study included patients undergoing D-EUS and I-EUS, in two centers for 28 years (03/1992 to 12/2019). Were noted parameters such as: age, gender, indication of EUS, modality, time of occurrence and severity of AE, type of treatment imposed and whether there was death. Descriptive analysis was performed using means, standard deviation and frequencies of the variables of interest. RESULTS: 13,196 procedures performed, 9843 D-EUS and 3353 I-EUS. Thirty-seven (0.3%) had AE with six deaths (0.04%). The overall rate of AE for D-EUS and I-EUS was 0.08% and 0.86%, respectively (p > .05). Three deaths (0.03%) occurred after D-EUS and three (0.09%) after I-EUS. AE were immediate and early in 70% and 30%, respectively, with no late complications. Perforation was detected immediately in 80% and early in 20%, being more frequent after D-EUS than I-EUS. Acute pancreatitis occurred immediately in 70% and early in 30%. The AE were mild, moderate, and severe in 35.1%, 27%, and 37.8%, respectively. Overall, D-EUS presented the majority of AE as severe (87.5%), while I-EUS presented mild AE in most cases (41.4%), followed by severe complications (24.1%). CONCLUSIONS: Despite the low incidence of AE and mortality after EUS, the occurrence of severe complications, especially perforation in D-EUS, may support the review of therapeutic protocols, aiming to ensure that a quality and safety process is implemented in the practice of EUS.

Pancreatic intraepithelial neoplasia (PanIN) is considered a pre-malignant lesion difficult to identify by imaging methods. EUSFNA is an effective technique to obtain material for histopathological study of pancreatic cystic tumors, but it is not free of adverse events. We report a case of a 56 years old patient, with chronic abdominal pain (early 1994). MRI showed pancreatic cystic images. The etiologic diagnosis was doubtful and EUS-FNA was performed. Immediately after a FNA, patient had an episode of acute pancreatitis, requiring hospitalization. During one year after FNA he had five episodes of AP. A new EUS suspected of PanIN, which was confirmed by surgery. After surgery the patient is well and has no more episodes of AP. Although the risk of AP, EUS-FNA should be performed to determine the best treatment for these patients with chronic abdominal pain who have cystic changes of pancreatic gland.

PURPOSE: To test the use of diffusion-weighted magnetic resonance imaging (DW-MRI) to differentiate between different degrees of severity of acute pancreatitis (AP). METHOD: Thirty-six patients who underwent DW-MRI and magnetic resonance cholangiopancreatography were divided into patients with mild AP (mAP, n = 15), patients with necrotizing AP (nAP, n = 8), and patients with a normal pancreas (nP, n = 15; controls). The pancreas was divided into head, body, and tail, and each segment was classified according to image features: pattern 1, normal; pattern 2, mild inflammation; and pattern 3, necrosis. Apparent diffusion coefficients (ADCs) were measured in each segment and correlated with clinical diagnoses. RESULTS: A total of 108 segments was assessed (three segments per patient). Segments classified as pattern 1 in the nP and mAP groups showed similar ADC values (P = 0.29). ADC values calculated for the pancreatic segments grouped according to the different image patterns (1-3) were significantly different (P < 0.001). Comparisons revealed significant differences in signal intensity between all three patterns (P < 0.05). CONCLUSIONS: DW-MRI was a compatible and safe image option to differentiate tissue image patterns in patients with mAP, nAP, and nP, mainly in those with contraindications to contrast-enhanced MRI (which is classically required for determining the presence of necrosis) or computed tomography. ADC measures allowed precise differentiation between patterns 1, 2, and 3.

OBJECTIVE: Widespread use of imaging procedures has promoted a higher identification of incidental pancreatic cysts (IPCs). However, little is known as to whether endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) could change the management strategy of patients having IPCs. This study has aimed to evaluate the management impact of EUS-FNA on IPCs. MATERIAL AND METHODS: Patients with pancreatic cysts (PCs) who were referred to EUS-FNA were recruited prospectively. The referring physicians were questioned about the management strategy for these patients before and after EUS-FNA. The impact of EUS-FNA on management was then evaluated. RESULTS: A total of 302 PC patients were recruited. Of these, 159 (52.6%) patients had asymptomatic IPCs. The average size was 2.3 cm (range: 0.2-7.1 cm), and 110 patients having smaller than 3 cm sized cysts. Lesions were located in the pancreatic head in 96 (61%) cases, and most patients (94%) had only a single cyst. The final diagnoses, obtained by EUS-FNA (91) and surgery (68), were 93 (58%) benign lesions, 36 (23%) cysts with malignant potential, 14 (9%) noninvasive malignancies, 10 (6%) malignant precursor lesions (PanIN), and 6 (4%) invasive malignancies. Management strategy changed significantly after EUS-FNA in 114 (71.7%) patients: 43% of the cases were referred to surgery, 44% of the patients were discharged from surveillance, and 13% of the cases were given further periodical imaging tests. CONCLUSION: EUS-FNA has a management impact in almost 72% of IPCs, with a major influence on the management strategy, either discharge rather than surgical resection or surgery rather than additional follow up.

BACKGROUND: ⢠The ERCP even when done by experienced professionals, fails in 10% of cases. BACKGROUND: ⢠Until the development of the EUS-BD, PTBD had a role as a rescue therapy, despite a high rate of adverse events. BACKGROUND: ⢠The EUS-BD is safe and has similar efficacy, when compared to PTBD and should be performed immediately after ERCP failure. BACKGROUND: ⢠A doctor with skills in both methods (ERCP/EUS) is needed to determine the best EUS-guided therapeutic option.

BACKGROUND: Paracoccidioidomycosis (PCM) may involve the hepatic pedicle and peripancreatic lymph nodes, cause damage to the bile duct and manifest, exceptionally, in combination with extrahepatic cholestasis (EHC), making investigation and treatment challenging. AIM: To investigate the management of patients with visceral PCM admitted with EHC. METHODS: All patients diagnosed with PCM treated in a public, tertiary teaching hospital between 1982 and 2020 were retrospectively evaluated. Those also identified with EHC were allocated to two groups according to the treatment approach for the purpose of comparing clinical, laboratory, and imaging findings, resources used for etiological diagnosis, treatment results, and prognosis. Statistical analyses were performed using the linear mixed-effects model (random and fixed effects), which was adjusted using the PROC MIXED procedure of the SAS® 9.0 software, and Fisher's exact test. RESULTS: Of 1645 patients diagnosed with PCM, 40 (2.4%) had EHC. Of these, 20 (50.0%) lived in the rural area and 29 (72.5%) were men, with a mean age of 27.1 years (3-65 years). Jaundice as first symptom and weight loss of at least 10 kg were observed in 16 patients (40.0%), and a mass in the head of the pancreas was observed in 8 (20.0%). The etiological diagnosis was made by tissue collection during surgery in 4 cases (10.0%) and by endoscopic methods in 3 cases (7.5%). Twenty-seven patients (67.5%) received drug treatment alone (Group 1), whereas 13 (32.5%) underwent endoscopic and/or surgical procedures in combination with drug treatment (Group 2). EHC was significantly reduced in both groups (40.7% in Group 1, with a mean time of 3 months; and 38.4% in Group 2, with a mean time of 7.5 months), with no statistically significant difference between them. EHC recurrence rates, associated mainly with treatment nonadherence, were similar in both groups: 37% in Group 1 and 15.4% in Group 2. The mortality rate was 18.5% in Group 1 and 23% in Group 2, with survival estimates of 71.3% and 72.5%, respectively, with no statistically significant difference. CONCLUSION: Although PCM-related EHC is rare, it needs to be included in the differential diagnosis of malignancies, as timely treatment can prevent hepatic and extrahepatic sequelae.
RESUMO
INTRODUCTION: The advantages of single-stage treatment of cholecystocholedocholithiasis are well established, but the conditions for carrying out treatment on an outpatient basis require a review of concepts and practices of medical corporations. OBJECTIVE: To evaluate the practice of treating cholecystocholedocholithiasis by laparoendoscopy on an outpatient basis with cost analysis. METHOD: A retrospective study was conducted on patients with cholecystocholedocholithiasis treated by combined laparoscopic cholecystectomy and endoscopic choledocholithotomy from January 2015 to January 2019. After collecting data from physical and digital medical records, the patients were divided into two groups-AR (n = 42)-ambulatory regimen and HR (n = 28)-hospitalization regimen-which were compared in terms of demographic, clinical and treatment variables and their results, as well as in terms of costs. RESULTS: The mean age of the AR group was lower than that of the HR group and the physical status of the AR patients was better when assessed according to the American Society of Anesthesiologists (ASA) (p = 0.01). There was no difference between groups regarding the risk of choledocholithiasis (p = 0.99). For the AR group, the length of stay was shorter: 11.29 h × 65.21 h (p = 0.02), as was the incidence of postoperative complications assessed by applying the Clavien-Dindo classification: 3 (7.1%) × 11 (39.2%) (p < 0.01). The total mean costs were higher for the HR group (USD 2489.93) than the AR group (USD 1650.98) (p = 0.02). CONCLUSION: Outpatient treatment of cholecystocholedocholithiasis by laparoendoscopy is safe and viable for most cases, has a lower cost and can support the reorientation of training and practice of hepatobiliary surgeons.
RESUMO
Background and study aims There are rare data on the usefulness of endosonography-guided tissue acquisition (EUS-TA) in patients with pancreatic cystic lesions (PCLs). This study aimed to determine the accuracy of EUS-TA with ProCore 20G (PC20) for differentiating between mucinous neoplasia (MN) and non-MNs (n-MN) and identifying malignant PCLs, as well as its adverse events (AEs) in patients with PCLs without a classificatory diagnosis by imaging exams. Patients and methods In this observational, retrospective, single-center study, all patients with PCL who underwent EUS-TA due to diagnostic doubts in imaging studies were consecutively recruited from June 2017 to December 2021. The outcomes were to determine the diagnostic accuracy of EUS-TA with PC20 for differentiating between MN and n-MN, identifying malignant PCLs, and the AEs. Results Herein, 145 patients underwent EUS-TA, with 83 women (57.2%) and a mean age of 62.2 years. The mean size was 2.3 cm, with 81 patients (77.9%) having a PCL < 3.0 cm. The final diagnosis was made by EUS-TA (n = 81), surgery (n = 58), and follow-up (n = 6). The sensitivity, specificity, positive and negative predictive values, and accuracy for differentiating between MNs and n-MNs and identifying malignant PCLs were 92.6%, 98.4%, 98.7%, 91.3%, and 95.2% (kappa=0.9), and 92%, 99.2%, 95.8%, 98.3%, and 97.9% (kappa = 0.93), respectively. The AE rate was 2.7%, with no deaths in this cohort. Conclusions EUS-TA with PC20 has high accuracy and technical success with a low AE rate for PCL diagnosis.

BACKGROUND: Metastases to the pancreas are rare, and usually mistaken for primary pancreatic cancers. This study aimed to describe the histology results of solid pancreatic tumours obtained by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for diagnosis of metastases to the pancreas. METHODS: In a retrospective review, patients with pancreatic solid tumours and history of previous extrapancreatic cancer underwent EUS-FNA from January/1997 to December/2010. Most patients were followed-up until death and some of them were still alive at the end of the study. The performance of EUS-FNA for diagnosis of pancreatic metastases was analyzed. Symptoms, time frame between primary tumour diagnosis and the finding of metastases, and survival after diagnosis were also analyzed. RESULTS: 37 patients underwent EUS-FNA for probable pancreas metastases. Most cases (65%) presented with symptoms, especially upper abdominal pain (46%). Median time between detection of the first tumour and the finding of pancreatic metastases was 36 months. Metastases were confirmed in 32 (1.6%) cases, 30 of them by EUS-FNA, and 2 by surgery. Other 5 cases were non-metastatic. Most metastases were from lymphoma, colon, lung, and kidney. Twelve (32%) patients were submitted to surgery. Median survival after diagnosis of pancreatic metastases was 9 months, with no difference of survival between surgical and non-surgical cases. Sensitivity, specificity, positive and negative predictive values, and accuracy of EUS-FNA with histology analysis of the specimens for diagnosis of pancreatic metastases were, respectively, 93.8%, 60%, 93.8%, 60% and 89%. CONCLUSION: EUS-FNA with histology of the specimens is a sensitive and accurate method for definitive diagnosis of metastatic disease in patients with a previous history of extrapancreatic malignancies.

â¢In pancreatic neoplasms the EUS plays a key role in the management. â¢During the pandemic period, lockdown measures prevented patients with comorbidities from performing EUS. â¢The D-EUS decreased during COVID-19, while I-EUS increased and EUS-TA was the most commonly I-EUS procedure performed, with no increase in adverse events. â¢Despite the moderate impact of the pandemic period in endoscopic services around the world, EUS-TA of solid and cystic tumors of the pancreas was the main indication. Background - Reports of the impact of the 2020 COVID-19 pandemic period/2020 on endoscopic ultrasound (EUS) are scarce. Objective - We analyzed the impact of the pandemic period/2020 on the demographics, indications, and number of diagnostic EUS (D-EUS) and interventional EUS (I-EUS) procedures performed in a high-volume endoscopy unit compared with the previous non-pandemic period/2019. Methods - We retrospectively reviewed the medical records of all patients undergoing D-EUS or I-EUS from March 1, 2019, to February 29, 2020 (non-pandemic period/2019) and from March 1, 2020, to February 28, 2021 (pandemic period/2020). Data compared between the study periods included sex, age, comorbidities, EUS findings and diagnosis, need for interventional procedures during EUS, and adverse events (AEs). Results were significant at P<0.05. Results - EUS procedures decreased from 475 in the non-pandemic period/2019 to 289 in the pandemic period/2020, accounting for a 39% reduction. In non-pandemic period/2019, 388 (81.7%) D-EUS and 88 (18.5%) I-EUS were performed, against 206 (71.3%) D-EUS and 83 (28.7%) I-EUS in pandemic period/2020 (P=0.001). Only 5/289 (1.7%) patients had COVID-19. Fewer patients with comorbidities underwent EUS during pandemic period/2020 due to lockdown measures (P<0.001). D-EUS decreased, whereas I-EUS increased (P<0.001). EUS-guided tissue acquisition (EUS-TA) was the most common I-EUS, performed in 83/289 (28.7%) patients in pandemic period/2020, against 88/475 (18.5%) in non-pandemic period/2019 (P=0.001). AEs did not differ significantly between the study periods. Conclusion - Pandemic Period/2020 had a moderate impact on reducing EUS procedures due to the risks involved. Although I-EUS increased, EUS-related AEs did not. Solid and cystic pancreatic tumors remained a major indication for EUS-TA even during the pandemic period/2020.

Introduction: Imaging diagnosis of pancreatic solid-pseudopapillary neoplasms (SPNs) is difficult. Preoperative diagnosis by endosonography-guided fine-needle aspiration (EUS-FNA) is possible and has been reported in the literature in pancreatic tumors. However, its usefulness is still controversial. The aim of this study was to determine the accuracy of the EUS-FNA in the diagnosis of patients with SPN and describe the findings in computerized tomography (CT), magnetic resonance cholangiopancreatography imaging (MRI/MRCP), and EUS therefore comparing the imaging methods alone to the findings of microhistology (McH) obtained by EUS-FNA. Materials and Methods: We retrospectively reviewed the medical records of patients undergoing EUS-FNA with suspected SPN in imaging studies in 5 Brazilian high-volume hospitals (two university hospitals and three private hospitals). The demographic data; findings in CT, MRI/MRCP, and EUS; and McH results obtained by EUS-FNA were noted prospectively. The final diagnosis was obtained after the anatomopathological examination of the surgical specimen in all patients (gold standard), and we compared the results of CT, MRI/MRCP, EUS, and the McH with the gold standard. Results: Fifty-four patients were included in the study, of which 49 (90.7%) were women with an average age of 33.4 (range 11-78) years. The most common symptom presented was abdominal pain, present in 35.2% patients. SPN was detected incidentally in 32 (59%) patients. The average size of the tumors was 3.8 cm (SD: 2.26). The most common finding at EUS was a solid, solid/cystic, and cystic lesion in 52.9%, 41.1%, and 7.8% patients, respectively. The final diagnosis was 51 patients with SPN and 3 with nonfunctioning pancreatic neuroendocrine tumors (NF-NET). The correct diagnosis was made by CT, MRI/MRCP, EUS isolated, and EUS-FNA in 21.9%, 28.88%, 64.71%, and 88.24%, respectively. EUS-FNA associated with CT and MRI increased diagnostic performance from 22.72% to 94.11% and from 29.16% to 94.11%, respectively. Conclusions: SPN are rare, incidentally identified in most cases, and affect young women. Differential diagnosis between SPN, NF-NET, and other types of tumors with imaging tests can be difficult. EUS-FNA increases preoperative diagnosis in case of diagnostic doubt and should be used whenever necessary to rule out NF-NET or other type of solid/cystic nodular lesion of the pancreas.
Introdução: O diagnóstico por imagem da neoplasia pseudopapilar sólida do pâncreas (NPS) é difícil. O diagnóstico pré-operatório obtido pela endosonografia com punção aspirativa por agulha fina (USE-PAF) é possível e tem sido relatado na literatura em tumores do pâncreas. No entanto, sua indicação é controversa e merece discussão. O objetivo do estudo foi determinar a acurácia da USE-PAF no diagnóstico de pacientes com NPS, descrever os achados da tomografia computadorizada (TC), colangiopancreatografia por ressonância magnética (RM/ CPRM) e USE, comparando os métodos de imagem isolados aos achados da microhistologia (McH) obtida pela USE-PAF. Material e Métodos: Revisamos retrospectivamente os prontuários de pacientes submetidos à USE-PAF com suspeita de NPS em exames de imagem de 5 hospitais brasileiros de alto volume (dois universitários e três privados). Foram anotados prospectivamente os dados demográficos, os achados da TC, RM/CPRM e USE e o resultado da McH obtida pela USE-PAF. O diagnóstico final foi obtido após o anatomopatológico da peça operatória em todos os pacientes (padrão-ouro). Comparamos os resultados da TC, RM/CPRM, EUS isoladas e da McH obtida pela USE-PAF com o padrão-ouro. Resultados: Cinquenta e quatro pacientes foram incluídos no estudo, 49 (90.7%) eram mulheres com média de idade de 33.4 (1178) anos. O sintoma mais frequente foi dor abdominal, presente em 35.2%. A NPS foi detectada acidentalmente em 32 (59%) pacientes. O tamanho médio da lesão foi de 3.8 cm (SD: 2.26). O achado mais comum à USE foi lesão sólida, sólida/ cística e cística em 52.9%, 41.1% e 7.8%, respectivamente. O diagnóstico final foi NPS (51) e tumor neuroendócrino pancreático não funcionante [NF-NET] (3). O diagnóstico correto feito pela TC, RM, USE e USE-PAF foi feito em 21.9%, 28.9%, 64.7% e 88.2%, respectivamente. A USEPAF associada a TC e a RM aumentou o desempenho diagnóstico de 21.9% para 94.1% e de 28.8% para 94.1%, respectivamente. Conclusões: NPS são raras, identificadas de forma acidental na maioria dos casos e afetam principalmente mulheres jovens. O diagnóstico diferencial entre NPS, NF-NET e outros tipos de lesões com exames de imagem isolados pode ser difícil. A USE-PAF aumenta a chance do diagnóstico pré-operatório em caso de dúvida diagnóstica e deve ser usado sempre que necessário para descartar NF-NET ou outro tipo de lesão nodular sólida ou sólido/cística do pâncreas.
RESUMO
INTRODUCTION: Cholecystectomy (CCY) is the gold standard treatment of acute cholecystitis (AC). Nonsurgical management of AC includes percutaneous transhepatic gallbladder drainage (PT-GBD) and endoscopic ultrasound-guided gallbladder drainage (EUS-GBD). This study aims to compare outcomes of patients who undergo CCY after having received EUS-GBD vs PT-GBD. METHODS: A multicenter international study was conducted in patients with AC who underwent EUS-GBD or PT-GBD, followed by an attempted CCY, between January 2018 and October 2021. Demographics, clinical characteristics, procedural details, postprocedure outcomes, and surgical details and outcomes were compared. RESULTS: One hundred thirty-nine patients were included: EUS-GBD in 46 patients (27% male, mean age 74 years) and PT-GBD in 93 patients (50% male, mean age 72 years). Surgical technical success was not significantly different between the 2 groups. In the EUS-GBD group, there was decreased operative time (84.2 vs 165.4 minutes, P < 0.00001), time to symptom resolution (4.2 vs 6.3 days, P = 0.005), and length of stay (5.4 vs 12.3 days, P = 0.001) compared with the PT-GBD group. There was no difference in the rate of conversion from laparoscopic to open CCY: 5 of 46 (11%) in the EUS-GBD arm and 18 of 93 (19%) in the PT-GBD group ( P value 0.2324). DISCUSSION: Patients who received EUS-GBD had a significantly shorter interval between gallbladder drainage and CCY, shorter surgical procedure times, and shorter length of stay for the CCY compared with those who received PT-GBD. EUS-GBD should be considered an acceptable modality for gallbladder drainage and should not preclude patients from eventual CCY.
