Abstract
BACKGROUND Cholecystitis is a major adverse event after self-expandable metallic stent placement for distal biliary obstruction (DBO). Covered self-expandable metallic stent (CSEMS) is being increasingly used, but few studies have investigated risk factors for cholecystitis limited to CSEMS. The present study aimed to identify risk factors for cholecystitis after CSEMS. METHODS Patients who underwent initial CSEMS placement for DBO between November 2014 and September 2021 were enrolled and followed-up until death, recurrent biliary obstruction, cholecystitis, or until March 2022. Cholecystitis within 30 days of CSEMS was defined as early cholecystitis and after 30 days as late cholecystitis. RESULTS Cholecystitis occurred in 51 of 339 patients (15%) after CSEMS. Forty-one patients (80.4%) had early cholecystitis, and 10 (19.6%) had late cholecystitis. Multivariate logistic regression analysis revealed that the maximum diameter of the common bile duct (CBD) (per 1 mm increase) (odds ratio [OR]: 0.87; 95% confidence interval [CI]: 0.76-1.00; p = .044), gallbladder stones (OR: 3.63; 95% CI: 1.62-8.10; p = .002), and tumor involvement in the cystic duct (CD) (OR: 4.87; 95% CI: 2.16-11.00; p < .001) were significant independent risk factors associated with early cholecystitis. No significant risk factors were identified for late cholecystitis. CONCLUSIONS A smaller CBD diameter, gallbladder stones, and tumor involvement in the CD were identified as risk factors for early cholecystitis development after CSEMS.

Abstract
BACKGROUND AND AIMS Acute cholecystitis is occasionally observed after biliary drainage using a covered self-expandable metal stent (CSEMS) for distal biliary obstruction (DBO). Gallbladder drainage before CSEMS placement may reduce cholecystitis. This study aimed to examine the preventive effect of endoscopic gallbladder stent placement (EGBS) on cholecystitis with CSEMSs. METHODS We retrospectively analyzed patients with DBO who underwent CSEMS placement across the orifice of the cystic duct between November 2014 and October 2021 and were negative for cholecystitis on biliary drainage. Prophylactic EGBS was attempted before CSEMS placement. The incidence of cholecystitis was compared between patients with and without EGBS. RESULTS In total, 286 patients (128 men; median age, 75 years) were included in this study. EGBS was attempted in 32 patients before CSEMS placement, and technical success was achieved in 24 patients (75%). Adverse events were noted in 3 patients (9.4%; penetration of cystic duct in 1 and acute pancreatitis in 2). The cumulative incidence of cholecystitis was significantly lower in patients with EGBS than in those without EGBS (1 [4.2%] vs 56 [21.4%], P = .045). In multivariable analysis, EGBS was a significant protective factor against cholecystitis (hazard ratio, .11; 95% confidence interval, .01-.79; P = .028). CONCLUSIONS Although the transpapillary approach to the gallbladder is not easy for patients with DBO, EGBS is effective in preventing cholecystitis associated with CSEMS placement.

Abstract
BACKGROUND Treatment for unresectable distal malignant biliary obstruction (DMBO) involves placing a 10-mm covered self-expandable metallic stent (CSEMS). In recurrent biliary obstruction (RBO), replacement of the CSEMS is recommended; however, the appropriate stent type remains unknown. We speculated that large-bore CSEMSs would provide longer patency. We compared the efficacy of 10-mm and 12-mm CSEMS in patients with RBO. METHODS We retrospectively retrieved data on patients who underwent CSEMS replacement from the endoscopic database. We investigated the time to RBO (TRBO) after CSEMS replacement. The hazard ratio (HR) for the the second TRBO was estimated using the Cox proportional hazard model. The estimated median second TRBO was determined using the Kaplan-Meier method. RESULTS Among the 493 patients with DMBOs treated with 10-mm CSEMS, 48 and 29 patients underwent re-intervention with 10-mm and 12-mm CSEMS, respectively. The use of 12-mm CSEMS was inversely associated with second TRBO (multivariable-adjusted HR, 0.62; 95% CI, 0.39-0.98; P = .042). The estimated median second TRBO was greater with the 12 mm CSEMS than with the 10 mm variety (562 days vs 207 days; P = .019). CONCLUSION The second intervention with 12-mm CSEMS was associated with a longer TRBO.

Abstract
OBJECTIVES Although covered self-expandable metal stents (CSEMSs) are associated with the risk of postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis due to pancreatic duct (PD) orifice obstruction, they are often used for biliary drainage treatment in malignant biliary obstruction (MBO). This study aimed to investigate the efficacy of PD stenting in preventing post-ERCP pancreatitis after CSEMS implantation. METHODS This retrospective cohort study analyzed 554 patients with transpapillary CSEMS for MBO. Patients with noninitial deployment, benign disease, CSEMS deployment above the papilla, surgically altered anatomy, uncovered self-expandable metal stents, multiple thin self-expandable metal stents, and unavailable procedure videos were excluded. Logistic regression analysis estimated the association between PD stenting and post-ERCP pancreatitis incidence. We adjusted for age, sex, pancreatitis history, prophylactic rectal nonsteroidal anti-inflammatory drug use, naïve papilla, MBO etiology, and prolonged biliary cannulation time. RESULTS Among 554 patients, 67 (12.1%) experienced post-ERCP pancreatitis. Post-ERCP pancreatitis was recorded in 13.7% of patients in the non-PD stenting and 4.3% in the PD stenting groups. Pancreatic duct stenting was associated with lower risks of post-ERCP pancreatitis (odds ratio [OR] 0.28; 95% confidence interval [CI] 0.099-0.79; P = 0.028). In multivariable analysis, the association between PD stenting and lower post-ERCP pancreatitis incidence was consistent (OR 0.19; 95% CI 0.062-0.58; P = 0.0034). CONCLUSIONS Pancreatic duct stenting could reduce the risk of post-ERCP pancreatitis after CSEMSs.

Abstract
BACKGROUND The depth of invasion determines the surgical method for treating gallbladder cancer (GBC). However, the preoperative correct diagnosis of invasion depth, especially discrimination of T1 lesions among sessile elevated GBCs, is difficult. We investigated the utility of preoperative endoscopic ultrasound (EUS) findings for diagnosing the invasion depth. METHODS We studied a sessile elevated GBC specimen diagnosed as a T1 lesion before developing our study protocol. EUS evidenced an intact boundary between the tumor and the inner hypoechoic layer (the intact boundary sign). To evaluate the potential of using this sign to diagnose T1 GBC as a primary outcome indicator, we retrospectively analyzed patients who underwent surgical resection of sessile elevated GBCs between April 2009 and March 2020. RESULTS Of the 26 surgically resected sessile elevated GBC specimens, 20 were included and six were excluded due to difficulty in evaluating the overall tumor or layer structure. The Kappa coefficient for interobserver agreement regarding the intact boundary sign was 0.733. The sensitivity and specificity of the sign for diagnosing T1 lesions were 0.857 and 1.000, respectively. CONCLUSION This new EUS finding could guide the accurate diagnosis of T1 lesions in patients with sessile elevated GBC.

Abstract
Although pancreatic neuroendocrine neoplasms (PNENs) are relatively rare tumors, their number is increasing with advances in diagnostic imaging modalities. Even small lesions that are difficult to detect using computed tomography or magnetic resonance imaging can now be detected with endoscopic ultrasound (EUS). Contrast-enhanced EUS is useful, and not only diagnosis but also malignancy detection has become possible by evaluating the vascularity of tumors. Pathological diagnosis using EUS with fine-needle aspiration (EUS-FNA) is useful when diagnostic imaging is difficult. EUS-FNA can also be used to evaluate the grade of malignancy. Pooling the data of the studies that compared the PNENs grading between EUS-FNA samples and surgical specimens showed a concordance rate of 77.5% (κ-statistic = 0.65, 95% confidence interval = 0.59–0.71, p < 0.01). Stratified analysis for small tumor size (2 cm) showed that the concordance rate was 84.5% and the kappa correlation index was 0.59 (95% confidence interval = 0.43–0.74, p < 0.01). The evolution of ultrasound imaging technologies such as contrast-enhanced and elastography and the artificial intelligence that analyzes them, the evolution of needles, and genetic analysis, will further develop the diagnosis and treatment of PNENs in the future.

Abstract
There are various reconstruction techniques that are used after upper gastrointestinal surgery. In recent years, opportunities for endoscopic diagnosis and treatment have been increasing in patients undergoing gastrointestinal surgery. With the advent of interventional endoscopic ultrasound (IV-EUS), various procedures have been developed mainly for patients in whom endoscopic retrograde cholangiopancreatography is difficult to carry out. Indications for such procedures are expanding. IV-EUS for surgically altered anatomy (SAA) includes EUS-guided fine-needle aspiration, biliary interventions (e.g. biliary drainage, treatment of bile duct stricture, removal of bile duct stones, and the rendezvous technique), and pancreatic interventions (e.g. rendezvous technique after Whipple surgery). In addition, there have been reports of various EUS-related procedures using a forward-viewing curved linear-array echoendoscope that are carried out for postoperative intestinal tract reconstruction. Although interventional EUS is a useful therapeutic procedure for SAA, there are still no dedicated devices, and standardization of the procedure is warranted.

Abstract
Background Methotrexate-associated lymphoproliferative disorder (MTX-LPD) can present as a benign lymphoid proliferation or a malignant lymphoma in patients taking MTX. Almost 50% of MTX-LPD cases show spontaneous remission after withdrawal of MTX treatment. Studies have suggested that the hyper-immune state of rheumatoid arthritis, the immunosuppressive state associated with MTX, and the carcinogenicity of the Epstein-Barr virus might contribute to MTX-LPD development. Although most cases of MTX-LPD occur at extranodal sites, few cases of MTX-LPD affecting the stomach and duodenum have been reported. To our knowledge, no other study has reported on the endoscopic observations of dramatic withdrawal and appearance of multiple digestive tract lesions in a short period of time. Herein, we report the clinical course and imaging findings of our case, which may be useful for understanding the pathological condition of MTX-LPD. Case presentation We describe the case of a 70-year-old woman with MTX-LPD of the stomach and duodenum. Disease regression was temporarily achieved after cessation of MTX treatment; however, it subsequently recurred, and complete response was only achieved after six cycles of rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisolone (R-CHOP) chemotherapy. Conclusions The first-choice therapy for patients taking MTX who develop suspected MTX-LPD should be the withdrawal of MTX treatment. Even after remission is achieved, patients should be kept under careful observation, and if the disease recurs, chemotherapy should be commenced promptly.

Abstract
Pulmonary tumor thrombotic microangiopathy (PTTM) is a high-mortality disease that is difficult to diagnose clinically. Our patient was an 80-year-old woman who came to us due to symptoms of increasing dyspnea. A clinical evaluation showed that she had hypoxemia and pulmonary arterial hypertension without any abnormalities in the major pulmonary arteries, bronchi, or alveoli. A lung perfusion scan showed multiple wedge-shaped perfusion defects. Further examination revealed adenocarcinoma in her right parotid gland with metastasis to the submandibular lymph nodes. We diagnosed her to have PTTM caused by a parotid tumor. The patient survived for 11 months with chemotherapy. An early antemortem diagnosis by minimally invasive examinations will help PTTM patients to survive longer.
