RESUMO
BACKGROUND: Dyspepsia is a very prevalent upper gastrointestinal tract symptoms complex. Some of these symptoms might arise from serious underlying diseases, so the promotion of evidence-based guidelines could potentially better align evaluation and treatment. AIM: To determine the value of alarm features as a predictive factor for significant endoscopic findings (SEFs) among hospitalized patients presenting with dyspepsia. METHODS: We conducted a retrospective case-control study including information about 6208 endoscopic procedures performed for hospitalized patients. Patients were divided into two groups, with and without SEFs, and compared to elucidate the ability of the different alarm features to predict SEFs. RESULTS: During the study, 605 patients fulfilled the inclusion criteria. When the demographics and clinical characteristics of the two groups were compared, tachycardia (P < 0.05), normocytic anemia, (P < 0.05), leukocytosis (P < 0.05), and hypoalbuminemia (P < 0.05) documented on admission prior to endoscopy were strong predictors of SEFs. Among the alarm features, upper gastrointestinal bleeding, persistent vomiting, odynophagia [odds ratio (OR) = 3.81, P < 0.05; OR = 1.75, P = 0.03; and OR = 7.81, P = 0.07, respectively] were associated with SEFs. Unexplained weight loss was strongly associated with malignancy as an endoscopic finding (OR = 2.05; P < 0.05). In addition, long-term use of anti-aggregate medications other than aspirin (P < 0.05) was correlated to SEFs. CONCLUSION: Novel predictors of SEFs were elucidated in this study. These parameters could be used as an adjunctive in decision making regarding performing upper endoscopy in hospitalized patients with dyspepsia.

BACKGROUND: We assessed efficacy and safety of endoscopic ultrasound-guided biliary drainage (EUS-BD) vs. endoscopic retrograde cholangiopancreatography (ERCP) as first-line intervention in malignant distal biliary obstruction (MDBO). METHODS: PubMed/Medline, Embase, and Cochrane databases were searched until 01â/12â/2023 for randomized controlled trials of EUS-BD vs. ERCP for primary biliary drainage in patients with inoperable MDBO. The primary outcome was technical success. Secondary outcomes were clinical success, adverse events, mean procedure time, 1-year stent patency, and overall survival. Relative risk (RR) with 95â%CI were calculated using a random effects model. RESULTS: Five studies (519 patients) were included. RR (95â%CI) for EUS-BD was 1.06 (0.96 to 1.17; Pâ=â0.27) for pooled technical success and 1.02 (0.97 to 1.08; Pâ=â0.45) for clinical success. 1-year stent patency was similar between the groups (RR 1.15, 0.94 to 1.42; Pâ=â0.17), with lower reintervention with EUS-BD (RR 0.58, 0.37 to 0.9; Pâ=â0.01). The RR was 0.85 (0.49 to 1.46; Pâ=â0.55) for adverse events and 0.97 (0.10 to 0.17; Pâ=â0.98) for severe adverse events. On subgroup analysis, EUS-guided placement of lumen-apposing metal stent (LAMS) outperformed ERCP in terms of technical success (RR 1.17, 1.01 to 1.35; Pâ=â0.03). Procedure time was lower with EUS-BD (standardized mean difference -2.36 minutes [-2.68 to -2.05; Pâ<â0.001]). CONCLUSIONS: EUS-BD showed a statistically significant lower reintervention rate than ERCP, but with similar technical success, stent patency, clinical success, and safety. Technical success of EUS-BD with LAMS was better than ERCP.
RESUMO
BACKGROUND: Dilatation of common bile duct (CBD) is mostly pathological and mainly occurs secondary to mechanical causes. We aimed to explore the prevalence of CBD dilatation in Intraductal Papillary Mucinous Neoplasms of the pancreas (IPMN) among patients referred to EUS. METHODS: A retrospective study of all patients who had an EUS diagnosis of IPMN from 2011 to 2019 at Galilee Medical Center were extracted. Control group including patients with other types of pancreatic cysts. RESULTS: Overall, 2400 patients were included in the study, of them 158 patients were diagnosed with pancreatic cysts, 117 patients (74%) diagnosed with IPMN (group A), and 41 patients (26%) diagnosed with other pancreatic cysts (group B). Univariate analysis showed significant association of IPMN (OR 3.8, 95% CI 1.3-11.5), resected gallbladder (GB) (OR 7.75, 95% CI 3.19-18.84), and age (OR 1, 95% CI 1.01-1.08) with CBD dilatation. Classifying IPMN to sub-groups using adjusted multivariate logistic regression analysis, only main duct-IPMN (MD-IPMN) significantly correlated with CBD dilatation compared to branch duct (BD)-IPMN and mixed type-IPMN (OR 19.6, 95% CI 4.57-83.33, OR 16.3, 95% CI 3.02-88.08). CONCLUSION: MD-IPMN was significantly correlated with dilated CBD. Assessment of the pancreas is warranted in encountered cases of dilated CBD without obvious mechanical cause.

OBJECTIVE: Endoscopic ultrasound guide fine needle biopsy (EUS-FNB) is the main diagnostic tool for pancreatic adenocarcinoma. In most instances, only histology is obtained via FNB, without sending cytological slides. The aim of our study was to assess the additive diagnostic yield of cytology performed through FNB. METHODS: We conducted a retrospective study of all patients with histological diagnosis of pancreatic adenocarcinoma who were diagnosed by EUS-FNB. RESULTS: Overall, 80 patients were included in the study period. The overall concordance between cytology and histology all FNB needles was 78.2%. Notably, cytological assessment improved the diagnostic yield for malignancy by 12.8%. The overall kappa coefficient correlation between histology and cytology was .501, 95% CI 0.361-0.641. However, the kappa correlation for suspicious of malignancy and malignant was excellent of .872, 95% CI 0.733-1, suggesting that cytology is crucial when histology is inconclusive. Further analysis showed that the Acquire and Sharkcore needles outperformed the Procore needle in term of concordance between cytology and histology (kappa correlation of .527, 95% CI 0.331-0.724, .515, 95% CI 0.265-0.764, and .297, 95% CI -0.051-0.646), respectively. CONCLUSION: Performing cytology specimen when using FNB improves the diagnostic yield in pancreatic adenocarcinoma.
RESUMO
Ascites is the most common complication of liver cirrhosis. Spontaneous bacterial peritonitis (SBP) is a common complication of ascites. The diagnosis is made by an ascitic fluid polymorphonuclear (PMN) cell count of ≥ 250/mm3. However, no other diagnostic test is present for the diagnosis of SBP. The aim of the study present study is to assess the diagnostic yield of ascitic calprotectin in SBP, and to explore whether it can predict disease stage. We performed a single center proof-of-concept prospective study including all patients with cirrhosis and ascites who underwent paracentesis. Overall, 31 patients were included in the study. Eight patients had SBP vs. 23 patients without SBP. Ascitic calprotectin level was 77.4 ± 86.5 µg/mL in the SBP group, as compared to 16.1 ± 5.6 µg/mL in the non-SBP group (P = 0.001). An ascitic calprotectin cut-off value of > 21 µg/mL was associated with sensitivity and specificity of 85.7% and 89.5%, respectively, with ROC of 0.947 (95% CI 0.783 to 0.997, P < 0.0001). Notably, ascitic calprotectin did not had a prognostic value in cirrhosis stage and prognosis. Ascitic calprotectin was highly accurate in the diagnosis of SBP. It can be a serve as adjunct for indefinite cases of SBP.

(1) Background: Pancreatic adenocarcinoma (PAC) is one of the most lethal types of cancer. Most cases of PAC occur in the head of the pancreas. Given the proximity of the pancreatic head to the bile duct, most patients present clinically during early stages of the disease, while distally located PAC could have delayed clinical presentation. (2) Aims: To assess predictors of non-head PAC. (3) Methods: A retrospective multicenter study was conducted, including all patients who had endoscopic ultrasound (EUS) for pancreatic masses and who had histologic confirmation of PAC. (4) Results: Of the 151 patients included, 92 (60.9%) had pancreatic head cancer, and 59 (39.1%) had distal pancreatic cancer. PAC at body was the most common location in the distal PAC group (31 patients (52.5%)). Logistic regression analysis demonstrated a significant association of obesity with distal migration of PAC (OR 4.44, 95% CI 1.15-17.19, p = 0.03), while none of the other assessed parameters showed a significant association. Notably, abdominal pain was more significantly associated with distal PAC vs. head location (OR 2.85, 95% CI 1.32-6.16, p = 0.008). (5) Conclusions: Obesity shows a significant association as a clinical predictor of distal PAC. Further studies are needed to better explore this association.
RESUMO
BACKGROUND: Foreign body ingestion in adults is commonly encountered in clinical practice. The therapeutic approach of whether to follow-up or extract is often controversial. AIM: We aimed to explore predictors for spontaneous passage of ingested foreign bodies by focusing on foreign body type, length, and location of impaction. METHODS: We performed a 12-year retrospective single-center study. Logistic regression analysis was done to identify predictors of spontaneous passage. RESULTS: Overall, 365 patients with foreign body ingestion were included. The rate of spontaneous passage was 53.7% in general, while the spontaneous passage rate was 47.9% in food impaction, 44.3% in sharp objects, 88.7% in blunt objects and only 22.2% in long blunt objects (> 6 cm). On regression analysis, esophageal location was associated with a higher impaction rate and lower spontaneous passage vs. stomach and small and large intestine (OR 0.15, 95% CI 0.07-0.31, OR 0.18, 95% CI 0.09-0.37 and OR 0.02, 95% CI 0.003-0.14), respectively. Performing Receiver operating characteristics (ROC) analysis found that the maximal length above which the foreign body will fail to pass spontaneously was 3.5 cm in the stomach and 3 cm in the small intestine, with area under the curve (AUC) of 0.8509 in stomach and 0.8073 in small intestine. CONCLUSION: Endoscopic removal was needed for all esophageal foreign bodies, and all foreign bodies more than 3.5 cm above the duodenum. Spontaneous passage of ingested foreign body in a selected cohort of patients depends on foreign body type, location, and length.

OBJECTIVE: Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) has been constantly increasing, particularly in the treatment of pancreatic neuroendocrine neoplasms (pNENs). While emerging data in this field are accumulating, we aimed to assess the pooled efficacy and safety of EUS-RFA for pNENs. METHODS: The PubMed/Medline, Embase, and Cochrane Library databases search was conducted to identify studies reporting EUS-RFA of pNENs with outcomes of interest (efficacy and safety). The primary outcome was radiological response. Efficacy was assessed by the pooled clinical response rate, whereas safety was assessed by the pooled adverse events (AEs) rate. Heterogeneity was assessed using I2. Pooled estimates and the 95% confidence interval (CI) were calculated using a random-effect model. RESULTS: Eleven studies involving 292 patients were included. The pooled technical success rate was 99.2% (95% CI 97.9-99.9%), with no heterogeneity. The pooled complete radiological response was 87.1% (95% CI 80.1-92.8%). The pooled partial response was 11.4% (95% CI 6.2-18.1%). The pooled clinical response rate for functional pNENs was 94.9% (95% CI 90.7-97.9%), with no heterogeneity. The pooled incidence of AEs was 20.0% (95% CI 14.0-26.7%); most AEs were mild to moderate in grade, while the pooled incidence of severe AEs was 0.9% (95% CI 0.2-2.3%). The most common AEs were transient mild abdominal pain in 19 patients (6.5%), and mild to moderate pancreatitis in 23 patients (7.9%). No cases of mortality were reported. CONCLUSION: Endoscopic ultrasound-guided radiofrequency ablation resulted on a feasible approach for pNENs treatment, with excellent technical success, high radiological and clinical response, and acceptable AE rate.

INTRODUCTION: Endoscopic ultrasound-guided fine needle aspiration and biopsy (EUS-FNA, -FNB) are the mainstay for tissue diagnosis of pancreatic lesions. Traditionally, FNA was performed for obtaining cytology and also histology if available from the puncture. Since their advent, however, FNB needles have been intended mainly to obtain core biopsies for histological specimens. AIMS: We aimed to assess the yield of cytology obtained via both FNA and FNB needles. METHODS: A retrospective study was performed including all patients who were diagnosed with pancreatic adenocarcinoma obtained via EUS-FNA/FNB needles. RESULTS: Overall, 227 patients were included. Of them, 85 patients underwent FNB, versus 142 patients who had FNA. The average age in the FNB group was 70.46 ± 11.29 years, versus 71.44 ± 11.80 in the FNA group, P = 0.57. Notably, cytological analysis diagnosed malignancy equally in both groups (69.4% in the FNB group, vs. 65.5% in the FNA group). The compatibility rate of cytology with histology was 76.5% in the FNB group, versus 76.1% in the FNA group (P = 0.69). The agreement level between cytology obtained by FNA and FNB, versus histology obtained by both needles, was moderate (kappa = 0.48, 95% CI 0.39-0.57). Similarly, the agreement level between cytology and histology in the FNB group was moderate as well (kappa = 0.5, 95% CI 0.36-0.64). CONCLUSION: Cytological assessment yielded an equal performance as compared to histological assessment with both needles. We recommend obtaining cytology specimens in pancreatic solid lesion puncture by FNB needle.

BACKGROUND: Acute gastrointestinal bleeding (GIB) is a commonly encountered medical emergency. In cases of negative endoscopic evaluations, computed tomography angiography (CTA) is usually the next diagnostic step. To date, data regarding positive CTA examinations are lacking. We aimed to assess the clinical and laboratory parameters that predict a positive CTA examination, as demonstrated by the extravasation of contrast material into the bowel lumen. METHODS: We performed a single-center retrospective study, including all patients who were admitted with GIB and who underwent CTA. Analysis was performed to compare patients' characteristics, and logistic regression was used to explore parameters associated with a positive CTA. RESULTS: We included 154 patients. Of them, 25 patients (16.2%) had active GIB on CTA vs. 129 patients (83.8%) who did not. On univariate analysis, several parameters were positively associated with active GIB, including congestive heart failure (OR 2.47, 95% CI 1.04-5.86, p = 0.04), warfarin use (OR 4.76, 95% CI 1.49-15.21, p = 0.008), higher INR (OR 1.33, 1.04-1.69, p = 0.02), and low albumin level (OR 0.37, 95% CI 0.17-0.79, p = 0.01). On multivariate logistic regression analysis, only high INR (OR 1.34, 95% CI 1.02-1.76, p = 0.03) and low albumin (OR 0.3, 95% CI 0.12-0.7, p = 0.005) kept their positive association with active bleeding, while a high ASA score was negatively associated with an active GIB. CONCLUSIONS: We could identify high INR and low albumin as strong predictors of active GIB, as demonstrated by positive CTA. On the other hand, comorbid patients classified by a high ASA score did not experience a higher rate of active GIB.
RESUMO
INTRODUCTION: Currently, the rate of bile duct injury and leak following laparoscopic cholecystectomy (LC) is still higher than for open surgery. Diverse investigative algorithms were suggested for bile leak, shifting from hepatobiliary scintigraphy (HBS) toward invasive and more sophisticated means. We aimed to analyze the use of biliary scan as the initial modality to investigate significant bile leak in the drain following LC, attempting to avoid potential unnecessary invasive means when the scan demonstrate fair passage of nuclear substance to the intestine, without leak. METHODS: We have conducted a prospective non-randomized study, mandating hepatobiliary scintigraphy first, for asymptomatic patients harboring drain in the gallbladder fossa, leaking more than 50 mL/day following LC. Analysis was done based on medical data from the surgical, gastroenterology, and the nuclear medicine departments. RESULTS: Among 3,124 patients undergoing LC, significant bile leak in the drain was seen in 67 subjects, of whom we started with HBS in 50 patients, presenting our study group. In 27 of whom, biliary scan was the only investigative modality, showing fair passage of the nuclear isotope to the duodenum and absence of leak in the majority. The leak stopped spontaneously within a mean of 3.6 days, and convalescence as well as outpatient clinic follow-up was uneventful. In 23 patients, biliary scan that was interpreted as abnormal was followed by endoscopic retrograde cholangio-pancreatography (ERCP). However, ERCP did not demonstrate any bile leak in 13 subjects. In 17 patients, ERCP was used initially, without biliary scan, suggesting the possibility of avoiding invasive modalities in 7 patients. CONCLUSIONS: Based on a negative predictive value of 91%, we suggest that in cases of asymptomatic significant bile leak through a drain following LC, a normal HBS as the initial modality can safely decrease the rate of using invasive modalities.
RESUMO
BACKGROUND: Pancreatic fat infiltration was shown to be linked with acute pancreatitis and probably its severity. These interesting findings merit more investigation to elucidate the effect of fatty pancreas on acute pancreatitis severity. METHODS: We performed a retrospective study of patients hospitalized with documented acute pancreatitis. Pancreatic fat was determined according to pancreas attenuation on computed tomography. Patients were divided into two groups, with and without fatty pancreas. The Systemic Inflammatory Response Syndrome (SIRS) score was compared. RESULTS: Overall, 409 patients were hospitalized with acute pancreatitis. Among them, 48 patients had fatty pancreas (group A), vs. 361 patients who did not (group B). The mean ± SD age in group A was 54.6â ±â 21.3, vs. 57.6â ±â 16.8 in group B ( P â =â 0.51). Patients in group A, had a significantly higher rate of fatty liver, as compared to group B (85.4% vs. 35.5%, P â <â 0.001). There was no significant difference in the medical history among the two groups. Fatty pancreas was associated with more severe acute pancreatitis as assessed by SIRS score at admission. The mean ± SD of SIRS score was significantly higher in group A (0.92â ±â 0.87), as compared to 0.59â ±â 0.74 in group B ( P â =â 0.009). Positive SIRS score was present in a significantly higher proportion of patients with fatty pancreas (25%), as compared to only 11.4% in group B ( P â =â 0.02). CONCLUSION: The occurrence of acute pancreatitis with higher SIRS score was significantly associated with fatty pancreas. Fatty pancreas may represent a predictor of acute pancreatitis severity.

BACKGROUND: Identification of pancreatic cancer (PC) local invasion is crucial to optimize patients' selection for surgery. AIMS: To determine the diagnostic accuracy of contrast-enhanced computed tomography (CECT) and endoscopic ultrasound (EUS) in local staging of PC. METHODS: We performed a multicenter study including all patients with PC who underwent surgery. RESULTS: One hundred twelve patients were included. Surgical findings of peri-pancreatic lymph nodes (LN), vascular and adjacent organ involvement were seen in 67 (59.8%), 33 (29.5%) and 19 patients (17%), respectively. The diagnostic performance of EUS was better than CECT in peri-pancreatic LN. The sensitivity, specificity, positive predictive value (PPV) and negative predictive (NPV) of CECT vs. EUS were 28.4%, 80%, 67.9% and 42.9% vs. 70.2%, 75.6%, 81% and 63%, respectively. For vascular and adjacent organ involvement, the sensitivity, specificity, PPV and NPV were 45.5%, 93.7%, 75%, 80.4% and 31.6%, 89.2%, 37.5% and 86.5% for CECT, respectively, vs. 63.6%, 93.7%, 80.8%, 86.1% and 36.8%, 94.6%, 58.3% and 88% for EUS, respectively. Combining both CECT and EUS, the sensitivity for peri-pancreatic LN, vascular and adjacent organ involvement improved (76.1%, 78.8% and 42%), respectively. CONCLUSION: EUS was superior to CECT in local staging. Combined EUS and CECT had a higher sensitivity than either alone.

PURPOSE: One-anastomosis gastric bypass (OAGB) is a relatively simple surgical procedure for those afflicted with severe obesity. Studies reported symptomatic biliary reflux gastritis and esophagitis as predominant complications. Hepatobiliary scintigraphy (HIDA) is the least invasive test for the diagnosis of bile reflux, with good sensitivity, patient tolerability, and reproducibility. The aim of this study was to define an optimized HIDA scintigraphy protocol for demonstrating bile reflux in post-OAGB patients. MATERIAL AND METHODS: We conducted a prospective multicenter study. Patients after OAGB with dyspeptic complaints were included. All patients underwent HIDA scan with a dedicated protocol for demonstrating bile reflux; prevalence and severity were reported. RESULTS: Nineteen patients were included, 18 females and one male, with mean age of 41.8 years and mean time of 22.4 months from operation to the scan. Bile reflux into the gastric pouch was documented in 11 patients (53%). Reflux to the stomach pouch was severe in three patients (27%), moderate in two patients (18%), and mild in six patients (55%). Bile reflux into the esophagus was documented in four patients (21%), severe reflux in one patient (25%), and mild in the other three (75%). A correlation was found between complaints of vomiting, heartburn and regurgitation, and findings of esophagitis on gastroscopy in patients with vs. without reflux. CONCLUSIONS: The tailored HIDA scan protocol detected bile reflux in more than half of the post-OAGB patients included in the study, with a high diagnostic sensitivity.

The role of endoscopic ultrasound (EUS) in the last two decades has shifted from a diagnostic tool to an important therapeutic tool treating mainly pancreato-biliary disorders. In recent years, its applications for treating pancreatic diseases have broadened, including the implementation of radiofrequency ablation (RFA), which has been traditionally used for treating solid tumors. In this critical in-depth review, we summarized all the papers throughout the literature regarding EUS-RFA for pancreatic neuroendocrine neoplasms, adenocarcinoma, and pancreatic cystic lesions. Overall, for pancreatic neuroendocrine neoplasms we identified 16 papers that reported 96 patients who underwent EUS-RFA, with acceptable adverse events that were rated mild to moderate and a high complete radiological resolution rate of 90%. For pancreatic adenocarcinoma, we identified 8 papers with 121 patients. Adverse events occurred in 13% of patients, mostly rated mild. However, no clear survival benefit was demonstrated. For pancreatic cystic lesions, we identified 4 papers with 38 patients. The adverse events were mostly mild and occurred in 9.1% of patients, and complete or partial radiological resolution of the cysts was reported in 36.8%. Notably, the procedure was technically feasible for most of the patients. Nevertheless, a long road remains before this technique finds its definite place in guidelines due to several controversies. EUS-RFA for pancreatic tumors seems to be safe and effective, especially for pancreatic neuroendocrine neoplasms, but multicenter prospective trials are needed to consider this treatment as a gold standard.

BACKGROUND: Gallstone disease is common worldwide and can lead to severe complications, including cholangitis; thus, it is important to identify modifiable risk factors for cholangitis. Proton pump inhibitors (PPIs) are commonly prescribed to treat gastroenterological disorders. We aimed to explore whether PPI use is associated with an increased risk of acute cholangitis in patients with gallstone disease. METHODS: This retrospective multicenter study included all patients arriving to the hospital over a 10-year period with various presentations of choledocholithiasis. We compared active PPI use in two groups: those with cholangitis (group A) vs. without cholangitis (group B). RESULTS: Overall, 811 patients were included, 161 in group A and 650 in group B. The average age ± standard deviation (SD) in groups A and B was 74.5 ± 20.6 vs. 61.6 ± 20.9 years, respectively. PPI use in group A was higher vs. group B (42.9% vs. 29.1%, p = 0.001). On univariate analysis, male gender (OR 1.47, 95% confidence interval (CI) 1.04-2.08), age (OR 1.04, 95% CI 1.03-1.05), ischemic heart disease (IHD) (OR 1.68, 95% CI 1.07-2.64), hyperlipidemia (OR 1.59, 95% CI 1.11-2.29), hypertension (OR 1.81, 95% CI 1.28-2.57) and PPI use (OR 1.83, 95% CI 1.28-2.61), all were associated with acute cholangitis. On multivariate analysis, only PPI use kept its association after adjustment for age (OR 1.64, 95% CI 1.2-3.7). CONCLUSIONS: Active PPI use was associated with a higher rate of cholangitis among patients with choledocholithiasis. We advocate considering this risk before prescribing PPIs to patients with gallstones. TRIAL REGISTRATION NUMBER: NHR-0263-20 received on 14/01/2021 date 'retrospectively registered'.

RESUMO
Antibioprohylaxis (ABP) for pancreatic cystic lesion is still a debated clinical indication. Although professional societies guidelines still recommend ABP in endoscopic ultrasound-fine needle aspiration (EUS-FNA) for pancreatic cystic lesions (PCL), this standard of care recommendation was based on old and weakly planned studies with a small number of patients. Herein, in this work, we provide a critical review with pooled data analysis of the available literature. Overall, the studies reported are weak and limited with small number of patients, the absence of exact definition of infection and the heterogenicity of the type and the duration of the ABP used. Pooled data analysis showed that the effect of ABP on the rate of cyst infection was not significant (OR 0.56, 95% CI 0.17-1.2), with no significant heterogenicity between the results of the studies reviewed and reported (as assessed by Breslow Day test for homogeneity of OR's [P = 0.15]). The pooled infection rate without ABP was 0.89% and 0.36% in the ABP group. Moreover, according to the pooled data infection rate, sample size calculation demonstrated that 6954 patients are needed to show superiority of ABP, with a number needed to treat of 179 patients to prevent single infection. However, through the literature only six studies (1660 patients) reported the cyst infection rate among ABP versus control, making these results scarce and biased by a small number of patients. Therefore, we suggest the need to revise the guidelines, until performing well organized large international study to solve this controversy.

BACKGROUND: Patients with acute idiopathic pancreatitis (AIP) should undergo further imaging tests such as endoscopic ultrasound (EUS) for further investigation. The time interval between an episode of AIP and EUS performance is still controversial. AIMS: We aimed to explore the optimal timing for performing EUS and to reveal parameters that might predict longer intervals needed for performing EUS. METHODS: We performed a single-center retrospective study at Galilee Medical Center from January 2015 to January 2020, at which point we included all patients who underwent EUS for further investigation of AIP. RESULTS: Overall, we included 50 patients. The average age of all patients was 54.2 ± 17.6 years (range 22-69 years), and more than half of the study cohort were males (58%). Classifying patients as inflamed vs. normal pancreatic tissue on EUS, we found that among patients with normal pancreatic tissue, EUS was performed 44.7 ± 28.3 days from discharge, while for patients with inflamed pancreatic tissue, it was 48.1 ± 22.3 days (p = 0.37) after discharge. Notably, the CT severity index was significantly associated with inflamed pancreatic tissue on EUS, as it was 2.4 ± 0.74 vs. 1.5 ± 1.3 in the normal pancreatic tissue group (p = 0.03). There were no differences in the Bedside index for severity in acute pancreatitis (BISAP) scores, and there were no differences in the average American Society of Anesthesiologist Physical Status (ASA) scores between the two groups. Notably, 26.3% of patients had inflamed pancreatic tissue when performing EUS at 4 weeks, as compared to 16% who had inflamed pancreatic tissue at EUS performed after 6 weeks. CONCLUSION: Radiological severity score was the only important factor in determining the time interval of performing EUS after an episode of AIP. Intervals greater than six weeks seem to be needed among patients with higher Balthazar scores.
RESUMO
The impressive technological advances in recent years have rapidly translated into the shift of endoscopic ultrasound (EUS) from diagnostic modality into an interventional and therapeutic tool. Despite the great advance in its diagnosis, the majority of pancreatic adenocarcinoma cases are inoperable when diagnosed, thus demanding alternative optional therapies. EUS has emerged as an easy, minimally invasive modality targeting this carcinoma with different interventions that have been reported recently. In this review we summarize the evolving role of interventional therapeutic EUS in pancreatic adenocarcinoma management.
