Abstract
BACKGROUND AND AIMS The difficulty of radiographic confirmation of the presence of stones remains a challenge in the treatment of intrahepatic bile duct (IHBD) stones in patients after hepaticojejunostomy (HJ). Peroral direct cholangioscopy (PDCS) enables direct observation of the bile duct and is useful for detecting and removing residual stones; however, its effectiveness is not clearly established in this clinical context. METHODS This single-center, single-arm, prospective study included 44 patients with IHBD who underwent bowel reconstruction with HJ during the study period. Stone removal was performed by short-type double-balloon enteroscopy (DBE). Following balloon-occluded cholangiography, the DBE was exchanged for an ultraslim endoscope through the balloon overtube for PDCS. The primary endpoint was the rate of residual stones detected by PDCS. Secondary endpoints were success rate of PDCS, residual stone removal with PDCS, procedure time for PDCS, procedure-related adverse events, and stone recurrence rate. RESULTS PDCS was successful in 39/44 patients (89%), among whom residual stones were detected in 16 (41%) (95% CI: 28%-54%). Twelve patients (75%) had residual stones <5 mm. Stone removal was successful in 15 (94%) patients and median procedure time for PDCS was 16 (IQR: 10-26) min. The rate of procedure-related adverse events was 7% (3/44), all of which improved with conservative treatment. During median follow-up of 2.1 years (IQR: 1.4-3.3), the overall probability of recurrence-free status at 1, 2, and 3 years was 100%, 92%, and 86%, respectively. CONCLUSIONS PDCS is a safe and effective procedure for complete stone removal in patients with IHBD stones after HJ.

Abstract
BACKGROUND AND STUDY AIMS Cholecystitis can occur after self-expandable metallic stent (SEMS) placement for malignant biliary obstructions (MBO). Furthermore, the best treatment option for cholecystitis has not been determined. Here, we aimed to identify the risk factors of cholecystitis after SEMS placement and determine the best treatment option. PATIENTS AND METHODS Incidence, treatments, and predictive factors of cholecystitis were retrospectively evaluated in 1,084 patients with distal MBO (DMBO) and 353 patients with hilar MBO (HMBO) who underwent SEMS placement at the 12 institutions from January 2012 to March 2021. RESULTS Cholecystitis occurred in 7.5% of patients with DMBO and 5.9% of patients with HMBO. The recurrence rate was significantly lower (p=0.043), and the recurrence-free period was significantly longer (p=0.039) in endoscopic procedures than in percutaneous procedures for cholecystitis treatment. Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) was better in terms of technical success, procedure time, and recurrence-free period than endoscopic transpapillary gallbladder drainage. The cases with obstruction across the cystic duct orifice by tumor (p=0.015) and those with obstruction by stent (p=0.037) were the independent risk factors for cholecystitis in DMBO. The cases with multiple SEMS placements (OR 11, 95% CI 0.68-190, p=0.091) and those with gallbladder stones (OR 2.3, 95% CI 0.92-5.6, p=0.075) had a higher risk for cholecystitis in HMBO. CONCLUSIONS The incidences of cholecystitis after SEMS placement for DMBO and HMBO were comparable. EUS-GBD is the optimal treatment option for patients with cholecystitis after SEMS placement for MBO.

Abstract
BACKGROUND EUS-FNA/B for pancreatic ductal adenocarcinoma (PDAC) is generally considered to be safe; however, while the incidence is low, there are occurrences of complications. Among these complications, there are serious ones like needle tract seeding (NTS), and it is not known than which types of tumors have the risks of EUS-FNA/B complications. This study aimed to evaluate the risk of EUS-FNA/B complications in patients with PDAC, focusing on morphological features. METHODS Overall, 442 patients who underwent EUS-FNA/B for solid pancreatic masses between January 2018 and May 2022 in four institutions were retrospectively surveyed. Finally, 361 patients histopathologically diagnosed with PDAC were analyzed. Among these patients, 79 tumors with cysts or necrotic components were compared with 282 tumors without cysts or necrotic components. The incidence and risk of EUS-FNA/B complications including NTS were evaluated. RESULTS There were 9 (2.4 %) of total EUS-FNA/B complications and 3 (0.8 %) of NTS. The incidence of total complication rate and NTS in tumors with cysts or necrotic components were significantly higher than in those without cysts or necrotic components (total complication 6.3 % vs. 1.4 %, p = 0.026, NTS 3.7 % vs. 0 %, p = 0.01). The transgastric route of puncture (OR: 93.3, 95 % CI: 3.81-2284.23) and the existence of cysts or necrotic components (OR: 7.3, 95 % CI: 1.47-36.19) were risk factors for EUS-FNA/B complications identified by the multivariate analysis. CONCLUSIONS We should pay attention to the risks of EUS-FNA/B complications, including NTS, when the tumor has cysts or necrotic components.

Abstract
Background Drainage exceeding 50% of total liver volume is a beneficial prognostic factor in patients with unresectable malignant hilar biliary obstruction (UMHBO). However, it is unclear what threshold percentage of total liver volume drained ('liver drainage rate') significantly improves survival in patients with UMHBO who received systemic chemotherapy. Objectives We aimed to assess the optimal liver drainage rate that improves survival in patients with UMHBO receiving chemotherapy using a three-dimensional (3D)-image volume analyzer. Design This study was a single-center retrospective cohort study. Methods Data from 90 patients with UMHBO who received chemotherapy after endoscopic biliary drainage using metal stents at Okayama University Hospital from January 2003 to December 2020 were reviewed. The liver drainage rate was calculated by dividing the drained liver volume by the total liver volume using a 3D-image volume analyzer. The primary endpoint was overall survival by liver drainage rate. The secondary endpoints were time to recurrent biliary obstruction (TRBO) and prognostic factors. Results The median total liver volume was 1172 (range: 673-2032) mL, and the median liver drainage rate was 83% (range: 50-100). Overall survival was 376 (95% CI: 271-450) days, and patients with >80% drainage (n = 67) had significantly longer survival than those with <80% drainage (n = 23) (450 days versus 224 days, p = 0.0033, log-rank test). TRBO was 201 (95% CI: 155-327) days and did not differ significantly by liver drainage rate. Multivariate Cox proportional hazards regression analysis revealed >80% liver drainage [hazard ratio (HR): 0.35, 95% CI: 0.20-0.62, p = 0.0003] and hilar cholangiocarcinoma (HR: 0.30, 95% CI: 0.17-0.50, p < 0.0001) as significant prognostic factors. Conclusion In patients with UMHBO scheduled for chemotherapy, >80% drainage is associated with improved survival. Further prospective multicenter studies are needed to verify the results of this study. Trail registration Okayama University Hospital, IRB number: 2108-011.

Abstract
We investigated the effect of modified FOLFIRINOX (mFFX) in unresectable pancreatic cancer by retrospectively analyzing the cases of 43 patients who underwent BRCA testing (germline, n=11; somatic, n=26; both germline and somatic, n=6). The association between BRCA mutations and therapeutic effect was clarified. Six patients tested positive for germline pathogenic variants. Familial pancreatic cancer (33% vs. 3%, p=0.006) and peritoneal disseminated lesions (66% vs. 8%, p<0.001) were significantly more common in patients with germline pathogenic variants. The partial response (PR) rate was 100% in the germline BRCA-positive patients, and 27% in the germline BRCA-negative patients (p<0.001). The median progression-free survival (PFS) was not reached for any germline BRCA-positive patients but was 9.0 months for the germline BRCA-negative patients (p=0.042). Patients with stage IV BRCA-associated pancreatic cancer had better overall survival than those with non-BRCA-associated pancreatic cancer, although the difference was nonsignificant (not reached vs. 655 days, p=0.061). Our results demonstrate that a PR and prolonged PFS can be expected in germline BRCA-positive patients after treatment with mFFX. Our findings also suggest that germline BRCA pathogenic variants may be useful as biomarkers for the therapeutic effect of mFFX in patients with pancreatic cancer.

Abstract
BACKGROUND The sedation method used during double-balloon endoscopic retrograde cholangiopancreatography (DB-ERCP) differs among countries and/or facilities, and there is no established method. This study aimed to evaluate the efficacy of non-anesthesiologist-administered propofol (NAAP) sedation using a target-controlled infusion (TCI) system during DB-ERCP. METHODS This retrospective study was conducted between May 2017 and December 2020 at an academic center. One hundred and fifty-six consecutive patients who underwent DB-ERCP were sedated by gastroenterologists using diazepam (n = 77) or propofol with a TCI system (n = 79), depending on the period. The primary endpoint was a comparison of poor sedation rates between the two groups. Poor sedation was defined as a condition requiring the use of other sedative agents or discontinuation of the procedure. Secondary endpoints were sedation-related adverse events and risk factors for poor sedation. RESULTS Poor sedation occurred significantly more often in the diazepam sedation group (diazepam sedation, n = 12 [16%] vs. propofol sedation, n = 1 [1%]; P = 0.001). Vigorous body movements (3 or 4) (diazepam sedation, n = 40 [52%] vs. propofol sedation, n = 28 [35%]; P = 0.038) and hypoxemia (< 85%) (diazepam sedation, n = 7 [9%] vs. propofol sedation, n = 1 [1%]; P = 0.027) occurred significantly more often in the diazepam sedation group. In the multivariate analysis, age < 70 years old (OR, 10.26; 95% CI, 1.57-66.98; P = 0.015), BMI ≥ 25 kg/m2 (OR, 11.96; 95% CI, 1.67-85.69; P = 0.014), and propofol sedation (OR, 0.06; 95% CI, 0.01-0.58; P = 0.015) were associated factors for poor sedation. CONCLUSIONS NAAP sedation with the TCI system during DB-ERCP was safer and more effective than diazepam sedation.

Abstract
INTRODUCTION Ceftriaxone (CTRX) is known to occasionally cause pseudolithiasis. This condition is often observed in children; however, few studies have reported the incidence and risk factors for CTRX-associated pseudolithiasis. METHODS In this single-center retrospective study, we investigated the incidence of and risk factors for CTRX-associated pseudolithiasis in adults. All patients underwent computed tomography to confirm pseudolithiasis before and after CTRX administration. RESULTS The study included 523 patients. Pseudolithiasis was detected in 89 patients (17%). Data analysis showed that abdominal area-related biliary diseases at the site of infection (odds ratio [OR] 0.19, 95% confidence interval [CI] 0.064-0.53, p = 0.0017), CTRX administration for >3 days (OR 5.0, 95% CI: 2.5-9.9, p < 0.0001), CTRX dose of 2 mg (OR 5.2, 95% CI: 2.8-9.6, p < 0.0001), fasting period >2 days (OR 3.2, 95% CI: 1.6-6.4, p = 0.0010), and estimated glomerular filtration rate <30 mL/min/1.73 m2 (OR 3.4, 95% CI: 1.6-7.5, p = 0.0022) were independent factors for pseudolithiasis. CONCLUSIONS CTRX-associated pseudolithiasis may occur in adults and should be considered in the differential diagnosis in patients who develop abdominal pain or liver enzyme elevation after CTRX administration, particularly in patients with chronic kidney disease, in those who are fasting, in and those who receive high-dose CTRX therapy.

Abstract
RATIONALE Duodenal wall perforation by a dislocated biliary stent placed for biliary structure is rare but can be life-threatening. There are few reports on the management of stent-related duodenal perforation. PATIENT CONCERNS Three cases included in this study had undergone endoscopic retrograde cholangiopancreatography with placement of a plastic stent for biliary stricture. Two cases had symptoms (fever or abdominal pain), while other case showed no symptom after biliary stent placement. DIAGNOSES Dislocation of plastic stents was revealed on computed tomography or endoscopic images. Two patients were diagnosed with duodenal perforation due to distal migration of long stents with a straight shape on the distal side. One patient was diagnosed with fistula formation between the intrahepatic bile duct and duodenum due to perforation of a pigtail stent. INTERVENTIONS All cases could successfully be managed endoscopically with closure by hemoclips or stent replacement. OUTCOMES All 3 cases were improved after endoscopic treatment without any subsequent intervention. LESSONS Longer stents with a straight distal side are associated with a higher risk of duodenal perforation. Endoscopic management is appropriate as a first-line approach for a clinically stable patient. At the time of stent placement, we should pay attention to the length and type of stent.

Abstract
BACKGROUND Gastric linitis plastica (GLP) is a subset of gastric cancer with a poor prognosis. It is difficult to obtain a definitive diagnosis by endoscopic mucosal biopsies, and the usefulness of an endoscopic ultrasonography-guided fine-needle biopsy (EUS-FNB) for GLP has been recently reported. Meanwhile, autoimmune diseases are occasionally known to coexist with malignant tumors as paraneoplastic syndrome. We herein report the usefulness of an EUS-FNB for detecting GLP and the possibility of paraneoplastic syndrome coexisting with GLP.
CASE SUMMARY An 81-year-old man was admitted to our hospital for a 1-mo history of epigastric pain that increased after eating. His laboratory data revealed high levels of serum carbohydrate antigen 19-9 and immunoglobulin-G4. Endoscopic examinations showed giant gastric folds and reddish mucosa; however, no epithelial changes were observed. The gastric lumen was not distensible by air inflation, suggesting GLP. Computed tomography showed the thickened gastric wall, the diffuse enlargement of the pancreas, and the peripancreatic rim, which suggested autoimmune pancreatitis (AIP) coexisting with GLP. Because the pathological findings of the endoscopic biopsy showed no malignancy, he underwent an EUS-FNB and was diagnosed with GLP. He received chemotherapy for unresectable gastric cancer due to peritoneal metastasis, after which both the gastric wall thickening and diffuse enlargement of the pancreas were improved.
CONCLUSION An EUS-FNB for GLP with a negative endoscopic biopsy is useful, and AIP may develop as a paraneoplastic syndrome.

Abstract
Objective Strict follow-up is recommended for branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs) to avoid missing the development of high-risk stigmata (HRS) at a premalignant stage. This study explored the risk factors associated with the development of HRS during follow-up. Methods We performed a retrospective analysis of 283 patients with BD-IPMN, treated at Okayama University Hospital in Japan between January 2009 and December 2016. Only patients with imaging studies indicative of classical features of BD-IPMN without HRS and followed for over one year were included in the study. We performed radiological follow-up every six months and collected patients' demographic data, cyst characteristics, and clinical outcomes and used univariate logistic regression models to determine the odds of developing HRS. Results Ten patients (3.5%) developed HRS after a median surveillance period of 55.8 months. The main pancreatic duct (MPD) size (5-9 mm) and cyst growth rate (>2.5 mm/year) were both suggested to be possible risk factors for the development of HRS [odds ratio, 14.2; 95% confidence interval (CI), 3.1-65.2, p=0.0006, and odds ratio, 6.1; 95% CI 1.5-25.5, p=0.014]. Regarding the number of worrisome features (WFs), the rate of HRS development was 2.0% (4/199) in cases with no WF, 1.6% (1/62) in cases with single WF and 22.7% (5/22) in cases with multiple WFs, respectively. The rate of HRS development was significantly higher in cases with multiple WFs than in the other cases (p<0.0001). Conclusion MPD dilation, rapid cyst growth, and multiple WFs were significant risk factors for the development of HRS. In the presence of such features, it is necessary to closely follow the development of HRS and avoid missing the best opportunity to perform surgical intervention.

Abstract
Background: Endoscopic retrograde cholangiopancreatography (ERCP) for extraction of common bile duct (CBD) stones in patients with Roux-en-Y gastrectomy (RYG) remains technically challenging. Methods: Seventy-nine RYG patients (median 79 years old) underwent short-type double-balloon enteroscopy-assisted ERCP (sDBE-ERCP) for CBD stones at three referral hospitals from 2011–2020. We retrospectively investigated the treatment outcomes and potential factors affecting complete stone extraction. Results: The initial success rates of reaching the papilla of Vater, biliary cannulation, and biliary intervention, including complete stone extraction or biliary stent placement, were 92%, 81%, and 78%, respectively. Of 57 patients with attempted stone extraction, complete stone extraction was successful in 74% for the first session and ultimately in 88%. The adverse events rate was 5%. The multivariate analysis indicated that the largest CBD diameter ≥ 14 mm (odds ratio (OR), 0.04; 95% confidence interval (CI), 0.01–0.58; p = 0.018) and retroflex position (OR, 6.43; 95% CI, 1.12–36.81; p = 0.037) were independent predictive factors affecting complete stone extraction achievement. Conclusions: Therapeutic sDBE-ERCP for CBD stones in a relatively elderly RYG cohort, was effective and safe. A larger CBD diameter negatively affected complete stone extraction, but using the retroflex position may be useful for achieving complete stone clearance.

Abstract
BACKGROUND Acute pancreatitis is a major adverse event of endoscopic retrograde cholangiopancreatography (ERCP). Rectal administration of non-steroidal anti-inflammatory drugs (NSAIDs) decreases the incidence of post-ERCP pancreatitis (PEP). However, the efficacy of low dose rectal NSAIDs for preventing PEP remains controversial. METHODS We performed a retrospective study of 301 patients with native papilla and a body weight of <50 kg who underwent ERCP between September 2010 and October 2019. After July 2016, a 25 mg dose of rectal diclofenac was routinely administered within 15 min before ERCP (NSAIDs group, n = 72) and the control group (n = 229) consisted of patients undergoing ERCP before this date without treatment. We compared the incidence of PEP between the two groups using propensity score matching. RESULTS A total of 66 pairs of patients in each group were selected. The patients and procedural-related factors were similar in both groups. In total, 15 patients (11.4%) developed PEP: 12.1% (8/66) in the NSAIDs group and 10.6% (7/66) in the control group (Odds ratio (OR) 1.2; 95% confidence interval (CI) 0.4-3.5; P = 0.78). There was no significant difference in incidence of other adverse events related to ERCP between the two groups. CONCLUSIONS Prophylactic administration of a 25 mg dose of rectal diclofenac did not reduce the incidence of PEP in patients with a native papilla and a body weight of <50 kg in this study and a certain dose of rectal NSAIDs, such as a 100-mg dose, should be administered regardless of body weight to prevent PEP.

Abstract
Background Only a few reports have assessed the effectiveness of endoscopic biliary drainage (EBD) in hepatocellular carcinoma (HCC) patients with obstructive jaundice and liver dysfunction. Methods This was a retrospective study based on the clinical databases from the Okayama University Hospital and 10 affiliated hospitals. All patients received EBD for jaundice or liver dysfunction. The indication for EBD was aggravation of jaundice or liver dysfunction with intrahepatic bile duct (IHBD) dilation. The technical and clinical success rate, complications, factors associated with clinical failure, and survival duration were evaluated. Results A total of 107 patients were enrolled in this study. Technical success was achieved in 105 of 107 patients (98.1%). Clinical success was achieved in 85 of 105 patients (81%). Complications related to endoscopic retrograde cholangiography (ERC) occurred in 3 (2.8%) patients. Child–Pugh class C (odds ratio 3.90, 95% confidence interval [CI] 1.47–10.4, p = 0.0046) was the only factor associated with clinical failure, irrespective of successful drainage. The median survival duration was significantly longer in patients with clinical success than in those without clinical success (5.0 months vs. 0.93 months; hazard ratio [HR] 3.2, 95% CI 1.87–5.37). HCC Stage I/II/III (HR 0.57, CI 0.34–0.95, p = 0.032), absence of portal thrombosis (HR 0.52, CI 0.32–0.85, p = 0.0099), and clinical success (HR 0.39, CI 0.21–0.70, p = 0.0018) were significant factors associated with a long survival. Conclusions EBD for obstructive jaundice and liver dysfunction in patients with HCC can be performed safely with a high technical success rate. Clinical success can improve the survival duration, even in patients expected to have a poor prognosis. Trial registration Retrospectively registered.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic treatment outcomes for hepatolithiasis in patients with altered anatomy are not well known. The aim of this study was to evaluate the treatment outcomes of hepatolithiasis in patients with hepaticojejunostomy (HJ) using short-type double-balloon endoscopy (sDBE) and to assess the risk factors for stone recurrence. PATIENTS AND METHODS This was a retrospective cohort study that consisted of 73 patients with hepatolithiasis who underwent bowel reconstruction with HJ at an academic center. Stone removal was performed using sDBE. After balloon-occluded cholangiography using sDBE, peroral direct cholangioscopy (PDCS) using ultraslim endoscopy was performed to check for residual stones, depending on the bowel reconstruction method. Recurrence was defined as the development of cholangitis from stones. RESULTS The success rate of reaching the HJ site was 92% (67/73), and the complete stone removal rate was 93% (62/67) with multiple sessions (mean number 1.5 ± 0.9). The occurrence rate of procedure-related adverse events was 6.8%. Among 58 patients evaluated for stone recurrence, 13 (22%) developed recurrence during a median follow-up period of 2.7 years (interquartile range: 1.5-4.8). Multivariate analyses determined that a stone diameter ≥ 8 mm [odds ratio (OR), 5.57; 95% confidence interval (CI), 1.39-37.2; p = 0.013] and performing PDCS (OR, 0.16; 95% CI, 0.0084-0.90; p = 0.036) were significant factors for stone recurrence. CONCLUSIONS Endoscopic treatment using sDBE for hepatolithiasis was effective and safe. PDCS might reduce the rate of stone recurrence by detecting stones that are too small to confirm on fluoroscopic images.

Abstract
Background Pancreatic juice cytology (PJC) is a tool for diagnosing malignant intraductal papillary mucinous neoplasm (IPMN); however, the accuracy is insufficient using the conventional method. Liquid-based cytology (LBC) improves the cell recovery rate, and almost all cells can be evaluated. We evaluated the efficacy of PJC with LBC for malignant IPMN. Methods We retrospectively analyzed 90 patients with suspected malignant IPMN who underwent PJC before pancreatectomy. PJC with smear and LBC methods was conducted in 52 patients (between June 2003 to December 2011) and 38 patients (between January 2012 to December 2018). Based on the imaging studies, all of the patients were classified according to the international consensus guidelines for IPMN revised in 2017. Results Of the 90 patients, 43 (48%) had malignant IPMN (high-grade dysplasia or invasive carcinoma), and the remaining patients had non-malignant IPMN (intermediate- or low-grade dysplasia). LBC increased the accuracy of PJC for the diagnosis of malignant IPMN (smear method: 56% [29/52] vs. LBC method: 76% [29/38]; P = 0.044). In a multivariate analysis, LBC was a significant factor influencing the accurate diagnosis of PJC (odds ratio: 3.52; P = 0.021). Furthermore, LBC increased the accuracy of PJC for malignant IPMN in patients with worrisome features (smear method: 66% [19/29] vs. LBC method: 93% [14/15]; P = 0.043). Conclusions LBC increases the accuracy of PJC for diagnosing malignant IPMN compared with the conventional smear method.

Abstract
Background/Aims Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA; EUS-FNA) allows for diagnostic tissue specimens from various regions to be analyzed. However, diagnosing recurrent pancreaticobiliary cancer after surgery is sometimes difficult. We evaluated the efficacy of EUS-FNA in the diagnosis of local recurrence of pancreaticobiliary cancer and analyzed the factors associated with falsenegative results. Methods Fifty-one consecutive patients who underwent EUS-FNA due to suspected recurrence of pancreaticobiliary cancer after surgery in an academic center were retrospectively analyzed. The criteria for EUS-FNA were a resected margin or remnant pancreas mass, round swollen lymph node (≥10 mm in diameter), and soft-tissue enhancement around a major artery. Patients with suspected liver metastasis or malignant ascites were excluded. Results Thirty-nine of the 51 patients had pancreatic cancer; the remaining 12 had biliary cancer. The target sites for EUS-FNA were the soft tissue around a major artery (n=22, 43%), the resected margin or remnant pancreas (n=12, 24%), and the lymph nodes (n=17, 33%). The median size of the suspected recurrent lesions was 15 mm (range, 8 to 40 mm). The overall sensitivity, specificity and accuracy of EUS-FNA for the diagnosis of recurrence was 84% (32/38), 100% (13/13), and 88% (45/51), respectively. FNA of the soft tissue around major arteries (odds ratio, 8.23; 95% confidence interval, 1.2 to 166.7; p=0.033) was significantly associated with a falsenegative diagnosis in the multivariate analysis. Conclusions EUS-FNA is useful for diagnosing recurrent cancer, even after pancreaticobiliary surgery. The diagnoses of recurrence at soft-tissue sites should be interpreted with caution.

Abstract
BACKGROUND Short-type double-balloon endoscope (DBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) has been developed as an alternative approach for cases with a surgically altered gastrointestinal anatomy. However, this technique is sometimes technically challenging and carries a risk of severe adverse events. AIMS To evaluate the factors affecting the technical success rate and adverse events of DBE-ERCP. METHODS A total of 319 patients (805 procedures) with a surgically altered gastrointestinal anatomy underwent short DBE-ERCP. The factors affecting the technical success rate and adverse events, and the learning curve of the trainees were retrospectively evaluated. RESULTS The technical success rate of all procedures was 90.7%. Adverse events occurred in 44 (5.5%) procedures. A multivariate analysis indicated that Roux-en-Y reconstruction and first-time short DBE-ERCP were factors affecting the technical failure and adverse event rates, while the modified Child method after subtotal stomach-preserving pancreaticoduodenectomy reconstruction was a non-risk factor for adverse events. The trainee caseload did not affect the technical success or adverse event rates significantly; however, trainees tended to perform cases involving the modified Child method after subtotal stomach-preserving pancreaticoduodenectomy reconstruction. The success rate of scope insertion increased according to experience; however, the overall success rate did not differ to a statistically significant extent. CONCLUSION Short DBE-ERCP was useful and safe for managing cases with a surgically altered anatomy; however, trainees should concentrate on accumulating experience with easy cases, such as those with the modified Child method after subtotal stomach-preserving pancreaticoduodenectomy reconstruction or a history of DBE-ERCP.

Abstract
BACKGROUND Endoscopic ultrasound is useful for obtaining high-resolution images of pancreaticobiliary diseases, but is not readily available for physical checkups. In this study, we evaluated the safety and efficacy of single-session esophagogastroduodenoscopy and endoscopic ultrasound in the detection of upper-gastrointestinal and pancreaticobiliary diseases using a forward-viewing radial scan ultrasonic endoscope. METHODS A total of 148 patients who were scheduled for upper-gastrointestinal screening using an endoscope were prospectively included. All patients were examined by EUS in combination with EGD using a forward-viewing radial scan ultrasonic endoscope. The primary endpoint was the safety of the procedures. The secondary endpoints were the prevalence of diseases, the basal imaging capability of EUS, the procedure time, total dose of propofol, and the correlation between background factors and the prevalence of pancreatic disease. The imaging capability at each region was scored as 0 (invisible) to 2 (sufficient visualization to evaluate the organs). RESULTS Intraoperative hypotension occurred as an adverse event of intravenous anesthesia in one patient. There were 82 pancreaticobiliary findings and 165 upper-gastrointestinal findings (malignancy not included). Follicular lymphoma of the intra-abdominal lymph nodes was detected in one patient. The mean imaging scores of each section were 1.95 (pancreatic head and papilla), 2.0 (pancreatic body), 1.99 (pancreatic tail), and 1.89 (common bile duct and gallbladder). Age, history of diabetes mellitus, and smoking history were significantly associated with the prevalence of pancreatic diseases. CONCLUSION The simultaneous performance of EGD and EUS using a new ultrasonic endoscope is tolerable and safe for upper-gastrointestinal and pancreaticobiliary screening.

Abstract
Esophageal lichen planus (ELP) is rare and only about 80 cases have been reported in the literature. An 85-year-old woman presented with dysphagia and odynophagia. Endoscopy revealed a severe stricture in the proximal esophagus. Oral examinations at two years after the first endoscopy revealed erosions around the gingiva, and an examination of biopsy specimens taken from the site of erosion led to a diagnosis of oral lichen planus. Esophageal endoscopy was performed again, and biopsy specimens showed spongiosis and necrotic keratinocytes in the epithelium (civatte bodies). The patient was diagnosed with ELP and was treated with systemic corticosteroids, which resulted in clinical relief.

Abstract
A 66-year-old woman was admitted to our hospital with heartburn and liver dysfunction. She was diagnosed with advanced gastric cancer. After the initiation of chemotherapy with trastuzumab, capecitabine, and cisplatin, she developed hyponatremia and renal failure with renal salt-wasting syndrome (RSWS). She recovered from these conditions after infusion of hypertonic saline. A diagnosis of RSWS should be considered in patients with hyponatremia who receive cisplatin-based chemotherapy.

Abstract
BACKGROUND AND STUDY AIMS Propofol administration via a target-controlled infusion system with bispectral index monitoring (BIS/TCI system) is expected to prevent complications from sedation during complex and long endoscopic procedures. We evaluated the feasibility of setting the BIS/TCI system for non-anesthesiologist administration of propofol (NAAP) during endoscopic submucosal dissection (ESD). PATIENTS AND METHODS From May 2009 to February 2013, 250 patients with esophagogastric neoplasms were treated with ESD using the BIS/TCI system with NAAP. In the TCI system, the initial target blood concentration of propofol was set at 1.2 μg/mL. The titration speed of propofol was adjusted according to the BIS score and the movement of the patient. The BIS target level ranged from moderate to deep sedation, at which a stable BIS score between 60 and 80 was obtained. RESULTS In 80.4 % of patients, it was possible to maintain stable sedation with a blood concentration of propofol of less than 1.6 µg/mL using TCI throughout the ESD procedure. The default setting for ideal blood concentration of propofol was 1.2 μg/mL, because the medians of the lower and upper bounds of blood concentration were 1.2 μg/mL (range 0.6 - 1.8 μg/mL) and 1.4 μg/mL (range 1.0 - 3.8 μg/mL), respectively. Although hypotension occurred in 27 patients (10.8 %), oxygen desaturation occurred in only nine patients (3.6 %), and severe desaturation in only two patients (0.8 %). CONCLUSIONS Using our settings, it is possible for a non-anesthesiologist to maintain stable sedation during a lengthy endoscopic procedure through propofol sedation with a BIS/TCI system.

Abstract
BCG-CWS was administrated into lymphatic vessels in the treatment of advanced malignant melanoma metastasized to the lymph node of the posterior peritoneum. Side effects consisted of fever, lymphangitis, a decrease in urinary output and a slight rise in serum GOT, there being no serious side effects. Clinically, tumor mass in the abdomen cleared but metastases to the other organs increased, and the patient died of general dispersion of the disease. At autopsy, the abdominal mass became flat, with the cut surface of yellowish brown color. Histologically, this mass formed necrosis made up of destroyed tumor cells and histiocytes. BCG-CWS mediated histiocyte response appeared to destroy tumor cells. Thus, it is possible that local administration BCG-CWS could elicit a potent response even in advanced carcinoma. Since the contact of BCG-CWS with tumor cells produced this response, administration of BCG-CWS into the lymphatic vessels may be indicated where the lymph current to the metastasized lymph node is not obstructed. This treatment would be effective particularly in the case of micrometastasis, and there is a possibility that it could elicit a specific response.
