Abstract
Endoscopic biliary drainage is the recommended 1st-line treatment for malignant biliary obstruction. Although a high incidence of febrile neutropenia has been reported in patients treated with FOLFIRINOX and a biliary stent, it remains unknown whether the biliary stent contributes to patient survival. Thus, we aimed to elucidate the effects of biliary stents on the survival of patients with advanced pancreatic cancer treated with modified FOLFIRINOX (mFFX). We retrospectively reviewed medical charts of patients with advanced pancreatic cancer treated with mFFX between January 2014 and April 2020. We compared the overall survival (OS) of patients with and without biliary stent during mFFX treatment and examined the independent effect on mortality using propensity score matching. Overall, we included 89 patients (stent group, n = 24; non-stent group, n = 65). The proportion of patients with pancreatic head cancer was significantly higher in the stent group than in the non-stent group (P < .01). Stratification analysis in patients with pancreatic head cancer revealed that OS was significantly shorter in the stent group than in the non-stent group (P = .03). After propensity score matching, 19 pairs of patients in each group were analyzed. The stent group revealed a significantly shorter survival than the non-stent group (median OS, 10.3 vs 24.9 months; P < .01). The incidences of febrile neutropenia (P = .01) and biliary tract-related events that required biliary stenting or stent replacement (P < .01) were significantly higher in the stent group than in the non-stent group. Stent insertion was an independent risk factor for overall mortality. Biliary stents may reduce survival in patients with advanced pancreatic cancer. The rate of febrile neutropenia was higher in the stent group than in the non-stent group. There is a need to assess the patient's condition with discretion and develop a treatment strategy with short prognosis in mind after stent insertion.

Abstract
BACKGROUND Studies have shown that covered self-expandable metallic stents (CSEMS) with a low axial forces after placement can cause early recurrent biliary obstruction (RBO) due to precipitating sludge formation.
AIM To ascertain whether the angle of CSEMS after placement is a risk factor for RBO in unresectable distal malignant biliary obstruction (MBO).
METHODS Between January 2010 and March 2019, 261 consecutive patients underwent self-expandable metallic stent insertion by endoscopic retrograde cholangiopancreatography at our facility, and 87 patients were included in this study. We evaluated the risk factors for RBO, including the angle of CSEMS after placement as the primary outcome. We measured the obtuse angle of CSEMS after placement on an abdominal radiograph using the SYNAPSE PACS system. We also evaluated technical and functional success, adverse events, time to RBO (TRBO), non-RBO rate, survival time, cause of RBO, and reintervention procedure as secondary outcomes.
RESULTS We divided the patients into two cohorts based on the presence or absence of RBO. The angle of CSEMS after placement (per 1° and per 10°) was evaluated using the multivariate Cox proportional hazard analysis, which was an independent risk factor for RBO in unresectable distal MBO [hazard ratio, 0.97 and 0.71; 95% confidence interval (CI): 0.94-0.99 and 0.54-0.92; P = 0.01 and 0.01, respectively]. For early diagnosis of RBO, the cut-off value of the angle of CSEMS after placement using the receiver operating characteristic curve was 130° [sensitivity, 50.0%; specificity 85.5%; area under the curve 0.70 (95%CI: 0.57-0.84)]. TRBO in the < 130° angle group was significantly shorter than that in the ≥ 130° angle group (P < 0.01).
CONCLUSION This study suggests that the angle of the CSEMS after placement for unresectable distal MBO is a risk factor for RBO. These novel results provide pertinent information for future stent management.

Abstract
Simple Summary Pancreatic cancer (PC) has a poor prognosis; however, diagnosing PC at an earlier stage could improve long-term patient outcomes. Endoscopic ultrasonography (EUS) plays an important role in PC detection, and the indirect findings (caliber change, retention cysts, and dilatation of the branch duct) that are detected by EUS are especially important for the early detection of PC. The aim of this retrospective study was to compare the diagnostic efficacy of radial- and convex-arrayed echoendoscope for the detection rate of indirect findings. As a result, the radial-arrayed echoendoscope was found to be an independent detection factor of indirect findings by multivariate analysis. The radial-arrayed echoendoscope is useful for the detection of indirect findings. Abstract Endoscopic ultrasonography (EUS) is useful for detecting early-stage pancreatic cancer. Because the detection of small lesions is difficult, it is important to detect indirect findings, namely caliber change, retention cysts, and dilatation of the branch duct, during the procedure. Although two types of EUS endoscopes are frequently used, there is no comparative study on their efficacy for detecting indirect findings. Therefore, we aimed to compare the diagnostic efficacy of these two types for indirect findings. We retrospectively analyzed 316 consecutive patients who had undergone EUS for pancreaticobiliary disease at a single center between January 2017 and December 2018. The main outcome was the detection rate of indirect findings and its comparison between the two echoendoscope types. This outcome was achieved using the inverse probability of treatment weighting (IPTW) analysis. The detection rate of indirect findings was higher for the radial-arrayed endoscope than for the convex-arrayed echoendoscope (9.2% vs. 2.3% (p = 0.02)). The univariate analysis also revealed that the radial-arrayed echoendoscope was significantly superior to the convex-arrayed echoendoscope in terms of the detection of indirect findings (odds ratio, 5.94; 95% confidence interval, 1.68–21.10; p = 0.01) after IPTW. After adjustment for magnetic resonance imaging (MRI) and computed tomography (CT), radial-arrayed echoendoscope remained an independent factor for indirect finding detection (odds ratio, 6.04; 95% confidence interval, 1.74–21.00; p = 0.01). Finally, five patients who had indirect EUS findings were diagnosed with pancreatic cancer. Our results indicate that the radial-arrayed echoendoscope is useful for the detection of indirect findings.

Abstract
Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) is safe and useful for the diagnosis of pancreatic cancer. However, sometimes a diagnosis cannot be established by EUS-FNAB. The efficacy of serial pancreatic juice aspiration cytological examination (SPACE) for pancreatic cancer was reported. SPACE may be useful in cases in which diagnosis by EUS-FNAB is difficult; however, this has not been reported previously. We herein report two cases of pancreatic cancer diagnosed by SPACE when diagnosis by EUS-FNAB was difficult. Case 1 was a 77-year-old female. She was suspected of pancreatic cancer because of new-onset diabetes. We performed EUS-FNAB to the lesion in the pancreatic body; however, diagnosis failed. We performed SPACE and diagnosed pancreatic cancer finally. Case 2 was 72 years old female. She was suspected of having pancreatic cancer because of the dilatation of the pancreatic duct. We performed EUS-FNAB twice to the lesion in the pancreatic head, however, diagnosis failed. Therefore, we performed SPACE and got final diagnosis as pancreatic cancer. From our experience, we suggest that SPACE is a useful diagnostic method for patients with pancreatic cancer that are difficult to diagnose.

Abstract
BACKGROUND AND AIM Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) remains the most common and serious adverse event associated with ERCP. Risk factors for PEP have been described in various reports. However, risk factors have not been quantified to date. The aim of this study was to investigate the risk factors for PEP by quantification of pancreatic volume using pre-ERCP images. METHODS Overall, 800 patients were recruited from April 2012 to February 2015 for this study. There were 168 patients who satisfied the inclusion criteria. Measurement of pancreatic volume was achieved using the volume analyzer SYNAPSE VINCENT in all cases and was used to evaluate the risk factors for PEP. RESULTS According to the criteria established by the consensus guidelines (Cotton classification), 17 patients (10.1%) were classified as having mild disease, 4 (2.4%) as having moderate disease, and 5 (3.0%) as having severe disease. Multivariate model analysis showed that a large pancreatic volume was a significant risk factor for PEP (odds ratio [OR] 1.10, 95% confidence interval [CI] 1.06-1.13; P < 0.001). In addition, the association between the pancreatic volume and the severity of PEP was positively correlated (the effect of volume [per 1 mL]; OR 1.09, 95% CI 1.07-1.12; P < 0.001, the effect of volume [per 10 mL]; OR 2.27, 95% CI 1.72-3.00; P < 0.001). A larger pancreatic volume was significantly associated with a higher incidence of PEP. CONCLUSIONS A large pancreatic volume was identified as a risk factor for PEP. The results of this study suggest that pre-ERCP images might be useful for predicting PEP.

Abstract
BACKGROUND & AIMS Advanced techniques have been developed to overcome difficult cannulation cases in endoscopic retrograde cholangiopancreatography (ERCP). Pancreatic duct guidewire placement method (PGW) is performed in difficult cannulation cases; it is possible that it places patients at risk of post-ERCP pancreatitis (PEP). The mechanism of PEP is still unclear, but pancreatic duct pressure and injury of pancreatic duct are known causes of PEP. Therefore, we hypothesized a relationship between pancreatic duct diameter and PEP and predicted that PGW would increase the risk of PEP in patients with non-dilated pancreatic ducts. This study aimed to investigate whether PGW increased the risk of PEP in patients with pancreatic duct diameter ≤ 3 mm. METHODS We analyzed 332 patients with pancreatic duct ≤ 3 mm who performed first time ERCP session. The primary endpoint was the rate of adverse event of PEP. We evaluated the risk of PEP in patients who had undergone PGW compared to those who had not, using the inverse probability of treatment weighting (IPTW) analysis. RESULTS PGW was found to be an independent risk factor for PEP by univariate analysis (odds ratio [OR], 2.45; 95% confidence interval [CI], 1.12-5.38; p = 0.03) after IPTW in patients with pancreatic duct diameter ≤ 3 mm. Adjusted for all covariates, PGW remained an independent risk factor for PEP (OR, 3.12; 95% CI, 1.33-7.33; p = 0.01). CONCLUSION Our results indicate that PGW in patients with pancreatic duct diameter ≤ 3 mm increases the risk of PEP.
