Abstract
When a pancreatic plastic stent for symptomatic chronic pancreatitis breaks during its removal, severe pancreatic duct stenosis may complicate its retrieval. Takuma and colleagues report on the successful retrieval of a fragmented and displaced pancreatic plastic stent by applying the two-device-in-one-channel method using forceps and a snare.

Abstract
Intrahepatic cholangiocarcinoma is a condition with a poor prognosis. Traditionally, there was no cure unless important drugs such as gemcitabine, cisplatin, and tegafur/gimeracil/uracil potassium showed efficacy. Pemigatinib has recently become accessible for the treatment of intrahepatic cholangiocarcinoma with FGFR2 fusion or rearrangement gene abnormalities. Hyperphosphatemia is typically linked to pemigatinib. In the current case, pemigatinib was used to effectively treat a 48-year-old woman, and hypophosphatemia was observed. Patients with intrahepatic cholangiocarcinoma should undergo aggressive cancer multigene panel testing as well as careful monitoring of serum phosphorus levels.

Abstract
Red dichromatic imaging is a new image-enhancement technology that clarifies the differences in blood concentrations and improves the visibility of the bleeding point. A 71-year-old man was presented with a common bile duct stone, which was completely removed using electrohydraulic shock wave lithotripsy with peroral cholangioscopy. During peroral cholangioscopy, a nodular lesion was found at the confluence of the cystic duct, and a forceps biopsy was performed. It was difficult to confirm the bleeding point using white-light imaging because of the pooling of blood. After switching to red dichromatic imaging mode 2 and washing the bile duct with saline solution, the bleeding point was observed in darker yellow than the surrounding blood, allowing the identification of the bleeding point. Red dichromatic imaging can be used in the future to maintain hemostasis during peroral cholangioscopy.

Abstract
BACKGROUND AND AIM Stent-induced ductal change (SIDC) is a complication of endoscopic pancreatic stenting (EPS) in patients with chronic pancreatitis (CP). However, the evaluation of SIDC associated with S-type pancreatic plastic stent (PS) and large-caliber PS, such as 10 Fr, is limited. This study aimed to analyze the SIDC of the main pancreatic duct (MPD) associated with 10-Fr S-type PS in patients with CP. METHODS Between January 2008 and December 2021, 132 patients with CP in whom a 10-Fr S-type PS had been installed by EPS were retrospectively reviewed. The SIDC incidence rate was examined, and the clinical features of patients with and without SIDC were investigated, including the outcomes for detected SIDC. RESULTS Stent-induced ductal change during EPS was confirmed in 41 patients (31.1%) of 132 patients at a site coincident with the PS tip or distal flap in the MPD. All patients were asymptomatic during the development of SIDC. Morphological changes in the MPD were detected as elevated (75.6%) or bearing stricture changes (24.4%). A total of 90.2% of SIDC developed after the first 10-Fr PS installation. No significant differences were noted between the patients with and without SIDC. The outcomes of continued PS installment for SIDC showed persistence and secondary change. CONCLUSIONS Stent-induced ductal change-associated 10-Fr PS installation was performed in just under one-third of the patients, indicating a substantial incidence rate and a possible development of SIDC from early stages onwards. More emphasis should be placed on SIDC as the complication.

Abstract
Background/Aims Many Japanese institutions use electromagnetic extracorporeal shock wave lithotripsy (ESWL) systems for treating pancreatic duct stones. However, there are no reports on direct comparisons between recent electromagnetic lithotripters. This study aimed to verify whether the new electromagnetic lithotripter can improve the efficiency of pancreatic stone fragmentation, and to clarify the role of combined endoscopic treatment on the clearance of pancreatic duct stones. Methods We retrospectively identified 208 patients with pancreatolithiasis who underwent endoscopic adjunctive treatment after pancreatic ESWL at a single Japanese center over a 17-year period. We evaluated the outcome data of this procedure performed with SLX-F2 (last 2 years; group A) and Lithostar/Lithoskop (first 15 years; group B), as well as additional endoscopic treatments for pancreatolithiasis. We also performed logistic regression analysis to detect various factors associated with the procedure. Results For pancreatic head stones, ESWL disintegration was achieved in 93.7% of group A patients and 69.0% of group B patients (p=0.004), and adjunctive endoscopic treatment removed stones in 96.8% of group A patients and 73.0% of group B patients (p=0.003). Multivariate analysis revealed that lithotripter type (odds ratio, 6.99; 95% confidence interval, 1.56 to 31.33; p<0.01) and main pancreatic duct stricture (odds ratio, 2.87; 95% confidence interval, 1.27 to 6.45; p<0.01) were significant factors for ESWL fragmentation. Conclusions The SLX F2 showed high performance in fragmenting the pancreatic duct stones. In addition, endoscopic adjunctive treatment improved the overall success rate of the procedure. The improved ESWL lithotripter has many advantages for patients undergoing pancreatic lithotripsy treatment.

Abstract
Annular pancreas is a congenital abnormality in which part of the pancreatic head completely or partially surrounds the duodenum in a ring-like manner. The condition is thought to be an abnormality of the ventral pancreatic bud. While pancreatitis is a common complication of the annular pancreas, its recurrence may be prevented by improving the outflow of pancreatic juice. The present case report describes a 23-year-old woman who had been referred to our hospital for recurrent pancreatitis since childhood. An endoscopic incision was made on the orifice of the annular pancreas, after which pancreatitis of the annular pancreas did not recur for 6 years. The patient subsequently exhibited pancreatolithiasis in the dorsal pancreatic duct, which was successfully treated with endoscopic treatment. Endoscopic pancreatic sphincterotomy may prevent the recurrence of pancreatitis and avoid further surgical interventions by improving the flow of pancreatic juice.

Laboratory studies showed increases in the peripheral white blood cell count and the level of C-reactive protein. Abdominal computed tomography depicted inflammation and a mass in the horizontal part of the duodenum. To observe it directly, we performed esophagogastroduodenoscopy (EGD), but it was very difficult to reach the lesion. Therefore, we performed enteroscopy by using SIF-H290S (Olympus Europa SE & Co. KG, Hamburg, Germany), which revealed a diverticulum containing food residue in the horizontal part of the duodenum. Using grasping forceps, we removed the food residue. The patient recovered over the next several days. Endoscopic therapy was thus effective for duodenal diverticulitis caused by food residue, but attention to technique was necessary.

Abstract
Background/Aims Endoscopic evaluation of intraductal papillary mucinous neoplasms (IPMNs) is useful in determining whether the lesions are benign or malignant. This study aimed to examine the usefulness of peroral pancreatoscopy (POPS) in determining the prognosis of IPMNs.
Methods POPS with videoscopy was performed using the mother–baby scope technique. After surgery, computed tomography/magnetic resonance cholangiopancreatography or ultrasonography and blood tests were performed every 6 months during the follow-up.
Results A total of 39 patients with main pancreatic duct (MPD)–type IPMNs underwent POPS using a videoscope, and the protrusions in the MPD were observed in 36 patients. The sensitivity and specificity of cytology/biopsy performed at the time of POPS were 85% and 87.5%, respectively. Of 19 patients who underwent surgery, 18 (95%) patients had negative surgical margins and 1 (5%) patient had a positive margin.
Conclusions In IPMNs with dilatation of the MPD, POPS is considered effective if the lesions can be directly observed. The diagnosis of benign and malignant lesions is possible depending on the degree of lesion elevation. However, in some cases, slightly elevated lesions may increase in size during the follow-up or multiple lesions may be simultaneously present; therefore, careful follow-up is necessary.

Abstract
Background/Aims Bleeding is a complication of endoscopic snare papillectomy for ampullary tumors. This study aimed to investigate the clinical efficacy of hypertonic saline-epinephrine (HSE) local injection before endoscopic papillectomy for prevention of bleeding.
Methods We retrospectively reviewed the data of 107 consecutive patients with ampullary tumors who underwent endoscopic papillectomy. The rates of en bloc resection, pathological resection margins, and prevention of immediate or delayed bleeding in the simple snaring resection group (Group A) and the HSE injection group (Group B) were compared.
Results A total of 44 and 63 patients were enrolled in Groups A and B, respectively. The total complete resection rate was 89.7% (96/107); the clinical complete resection rates in Group A and Group B were 86.3% (38/44) and 92.1% (58/63), respectively (p=0.354). Post-papillectomy bleeding occurred in 22 patients. In Groups A and B, the immediate bleeding rates were 20.5% (9/44) and 4.8% (3/63), respectively (p=0.0255), while the delayed bleeding rates were 7% (3/44) and 11% (7/63), respectively (p=0.52). The rates of positive horizontal and vertical pathological margin in both groups were 27% and 16%, respectively.
Conclusions HSE local injection was effective in preventing immediate bleeding and was useful for safely performing endoscopic papillectomy for ampullary tumors.

Abstract
Pancreatic leiomyosarcoma (PLMS) is an extremely rare tumor that accounts for 0.1% of pancreatic malignancies, and its chemotherapy has yet to be established. Generally, soft-tissue sarcoma chemotherapy is standard treatment with doxorubicin (DXR) alone. However, the effectiveness of gemcitabine (GEM) plus docetaxel (DOC) has been shown in uterine leiomyoma. In contrast, the GEM plus nab-paclitaxel (PTX) regimen has been established as first-line chemotherapy for unresectable pancreatic cancer. For this study, we selected the GEM plus nab-PTX regimen for patients with PLMS, achieving success in approximately 10 months. From a search on PubMed, we found only 12 cases of PLMS (including this case) that underwent chemotherapy. Our case is the first reported patient to have survived more than 2 years with chemotherapy alone. In a nude mouse model, the GEM plus DOC regimen was shown to significantly decrease tumor size when compared with DXR in leiomyosarcoma, and the GEM plus nab-PTX regimen was reported to significantly reduce necrosis when compared with DXR alone, GEM alone, DOC alone, nab-PTX alone and GEM plus DOC in soft-tissue sarcoma. GEM plus nab-PTX therapy might therefore be the first choice for soft-tissue sarcoma and leiomyosarcoma. This is the first reported case of PLMS treated with GEM plus nab-PTX.

Abstract
BACKGROUND Gemcitabine plus cisplatin (GC) is the standard treatment of advanced biliary tract cancer (BTC); however, it causes nausea, vomiting, and anorexia, and requires hydration. Gemcitabine plus S-1 (GS) reportedly has equal to, or better, efficacy and an acceptable toxicity profile. We aimed to confirm the non-inferiority of GS to GC for patients with advanced/recurrent BTC in terms of overall survival (OS). PATIENTS AND METHODS We undertook a phase III randomized trial in 33 institutions in Japan. Eligibility criteria included chemotherapy-naïve patients with recurrent or unresectable BTC, an Eastern Cooperative Oncology Group Performance Status of 0 - 1, and adequate organ function. The calculated sample size was 350 with a one-sided α of 5%, a power of 80%, and non-inferiority margin hazard ratio (HR) of 1.155. The primary end point was OS, while the secondary end points included progression-free survival (PFS), response rate (RR), adverse events (AEs), and clinically significant AEs defined as grade ≥2 fatigue, anorexia, nausea, vomiting, oral mucositis, or diarrhea. RESULTS Between May 2013 and March 2016, 354 patients were enrolled. GS was found to be non-inferior to GC [median OS: 13.4 months with GC and 15.1 months with GS, HR, 0.945; 90% confidence interval (CI), 0.78-1.15; P = 0.046 for non-inferiority]. The median PFS was 5.8 months with GC and 6.8 months with GS (HR 0.86; 95% CI 0.70-1.07). The RR was 32.4% with GC and 29.8% with GS. Both treatments were generally well-tolerated. Clinically significant AEs were observed in 35.1% of patients in the GC arm and 29.9% in the GS arm. CONCLUSIONS GS, which does not require hydration, should be considered a new, convenient standard of care option for patients with advanced/recurrent BTC. CLINICAL TRIAL NUMBER This trial has been registered with the UMIN Clinical Trials Registry (http://www.umin.ac.jp/ctr/index.htm), number UMIN000010667.

Abstract
AIM Endoscopic pancreatic stenting for refractory pancreatic duct strictures associated with impacted pancreatic stones in chronic pancreatitis cases has yielded conflicting results. We retrospectively evaluated the efficacy of endoscopic treatment in chronic pancreatitis patients with pancreatic duct strictures. METHODS Pancreatic sphincterotomy, dilatation procedures, pancreatic brush cytology, and pancreatic juice cytology were routinely performed, and malignant diseases were excluded. After gradual dilatation, a 10 Fr plastic pancreatic stent was inserted. The stents were replaced every 3 months and removed after the strictures were dilated. Statistical analyses were performed to determine the risk of main pancreatic duct restenosis. RESULTS Endoscopic pancreatic stents were successfully placed in 41 of a total of 59 patients (69.5%). The median duration of pancreatic stenting was 276 days. Pain relief was obtained in 37 of 41 patients (90.2%). Seventeen patients (41.5%) had recurrence of main pancreatic duct stricture, and restenting was performed in 16 patients (average placement period 260 days). During the follow-up period, pancreatic cancer developed in three patients (5.1%). Multivariate analysis revealed that the presence of remnant stones after stenting treatment was significantly associated with a higher rate of main pancreatic duct restenosis (p = 0.03). CONCLUSION The use of 10 Fr S-type plastic pancreatic stents with routine exchange was effective for both short-term and long-term outcomes in chronic pancreatitis patients with benign pancreatic duct strictures and impacted pancreatic stones.

Abstract
We compared the benefits of sorafenib with that of hepatic arterial infusion chemotherapy (HAIC) for advanced hepatocellular carcinoma (ad-HCC) refractory to transcatheter arterial chemoembolization (TACE). We evaluated the patient characteristics, the median survival time (MST), and the prognostic factors in 17 patients in the sorafenib group and in 26 patients in the HAIC group. No significant difference was observed in the patient characteristics between the groups. The MST in the sorafenib group and HAIC group was 483 days and 284 days, respectively. A significantly longer survival time was noted in the sorafenib group (p=0.033). The prognostic factors were sorafenib therapy in all 43 patients(hazard ratio: 3.32 [95% CI: 1.36-8.10], p=0.008) and the longer treatment period of sorafenib in the sorafenib group(hazard ratio: 0.99 [95% CI: 0.984- 0.999], p=0.009). When compared with HAIC, sorafenib showed favorable treatment results in patients with ad-HCC refractory to TACE.

Abstract
To determine useful factors when selecting an appropriate procedure for noninvasive ampullary neoplasia, we investigated the relationship between the location and the histomorphological/immunohistochemical characteristics of 56 noninvasive ampullary neoplasms obtained by endoscopic papillectomy (EP). All subjects were classified according to histomorphology and location of neoplasms, and we evaluated the characteristics of each classified group using complementary immunohistochemical procedures. The CK20-positive rates of each location type were also evaluated. Subjects presented with 52 intestinal-type adenomas (low/high grade, 32:20) and 4 noninvasive pancreatobiliary papillary neoplasms (low/high grade, 1:3). Twenty-seven periampullary (peri-AMP)-type tumors and 23 extended-type tumors comprised the intestinal type, and the intra-ampullary (intra-AMP) type was composed of 4 pancreatobiliary and 2 intestinal histomorphological types. The CK20-positive rates of these 3 location types differed significantly (peri-AMP type, 50.6% ± 21.0%; extended type, 35.4% ± 18.6%; intra-AMP type, 6.9% ± 6.3%). The CK20-positive rate for intestinal-type tumors of the intra-AMP location type was lower than that of the peri-AMP location type. Intestinal-type tumors without CDX2 expression included extended and intra-AMP types, which are tumors that may show positive vertical margins when EP is performed. In this study, we found that an understanding of pancreatobiliary-type histology is an important aspect for the investigation of tumors involving the common channel of the ampulla. Furthermore, immunostaining of CDX2 and CK20 provides beneficial information if considering whether to perform an EP.

Abstract
BACKGROUND/AIMS This prospective non-randomized controlled trial aimed to compare the efficacy of sorafenib vs hepatic arterial infusion chemotherapy (HAIC) for advanced hepatocellular carcinoma. METHODOLOGY Forty-seven patients treated with sorafenib (sorafenib group) and 77 patients treated with HAIC (HAIC group) were investigated retrospectively using propensity score matching (PSM) to minimize selection bias. The cumulative survival rate was investigated before and after PSM in each of the sorafenib and HAIC groups. The cumulative survival rate was compared between the sorafenib and HAIC groups, and among the TNM stage by the Liver Cancer Study Group of Japan (LCSGJ TNM stage). RESULTS No significant difference was noted in overall survival (OS) between the sorafenib and HAIC groups regardless of before or after PSM. On comparison of the cumulative survival rate between the groups by the same LCSGJ TNM stage, significant prolongation of OS was noted in stage IVB only in the sorafenib group (p = 0.032) after PSM. CONCLUSIONS It may be better to actively introduce sorafenib for stage IVB, i.e., patients with extrahepatic metastasis.

Abstract
Background/Aims In recent years, endoscopic snare papillectomy has been performed to treat tumors of the ampulla of Vater. This procedure requires accurate preoperative evaluation. In this study, we diagnosed the focal extension of such tumors by using endoscopic ultrasonography (EUS) and intraductal ultrasonography (IDUS), and examined the indications for endoscopic snare papillectomy. Methods The subjects were 48 patients with a papillary tumor (13 patients, surgical resection; 35 patients, endoscopic snare papillectomy) who were evaluated preoperatively with EUS and IDUS. The tumor-node-metastasis classification was used for the endosonographic evaluation and pathological diagnosis of these tumors. Results The diagnostic accuracy of EUS was 97% for diagnosing adenomas and pTis tumors, 73% for pT1 tumors, 50% for pT2 tumors, and 50% for pT3-4 tumors, for an overall accuracy of 85% for T-staging. The diagnostic accuracy of IDUS was 94% for adenomas and pTis tumors, 73% for pT1 tumors, 50% for pT2 tumors, and 100% for pT3-4 tumors, for an overall accuracy of 80% for T-staging. Conclusions EUS and IDUS are highly capable of evaluating tumors of the ampulla of Vater preoperatively. However, these techniques are not sufficient for evaluating the focal extension of carcinomas preoperatively. Currently, endoscopic snare papillectomy is adequate for treating adenomas and pTis tumors.

Abstract
BACKGROUND AND STUDY AIMS Despite the development of peroral video cholangioscopy (PVCS), no prospective multicenter studies have been undertaken to investigate the diagnostic accuracy of PVCS in biliary tract diseases. Therefore, the aim of this study was to clarify the accuracy of PVCS in evaluating biliary tract lesions. PATIENTS AND METHODS This study was a prospective multicenter study at five tertiary referral centers in Japan and included 87 eligible patients with biliary tract diseases who underwent PVCS. The study evaluated the ability of PVCS to diagnose indeterminate biliary tract diseases, detect mucosal cancerous extension preoperatively in extrahepatic bile duct cancers, and predict adverse events. RESULTS The use of PVCS appearance alone correctly distinguished benign from malignant indeterminate biliary lesions in 92.1 % of patients whereas biopsy alone was accurate in 85.7 %. In extrahepatic bile duct cancer, mucosal cancer extended histologically at least 20 mm in 34.7 % (17/49) of patients. The accuracy rate of PVCS to evaluate the presence or absence of mucosal cancerous extension by endoscopic retrograde cholangiography (ERC) alone, ERC with PVCS, and ERC with PVCS + biopsy were 73.5 %, 83.7 %, and 92.9 %, respectively. Adverse events were seen in 6.9 % of PVCS patients, but no serious complications were observed. CONCLUSION PVCS enhanced the accurate diagnosis of biliary tract lesions by providing excellent resolution in combination with biopsy.

Abstract
A 44-year-old man presenting to our hospital emergency room with abdominal pain was hospitalized for hyperlipidemic acute pancreatitis. A pig-tail catheter was placed percutaneously to drain an abscess on day 22. Although the abscess improved gradually and good clinical progress was seen, pancreatic duct disruption was strongly suspected and endoscopic retrograde cholangiopancreatography was performed on day 90. An endoscopic nasopancreatic drainage tube was placed, but even with concurrent use of a somatostatin analogue, treatment was ineffective. Surgical treatment was elected, but was subsequently postponed as the abscess culture was positive for extended-spectrum β-lactamase-producing Escherichia coli and methicillin-resistant Staphylococcus aureus. Drainage tubography showed a small fistula of the colon at the splenic flexure on day 140. Colonoscopy was performed on day 148. After indigo carmine had been injected, a fistula into the splenic flexure of the colon showed blue staining. The over-the-scope clip (OTSC) system was used to seal the fistula and complete closure was shown. A liquid diet was started on day 159 and was smoothly upgraded to a full diet. Following removal of the pancreatic stent on day 180, drainage volume immediately decreased and the percutaneous drain was removed. On day 189, computed tomography showed no exacerbation of the abscess and the patient was discharged on day 194. This case of colonic fistula caused by severe acute pancreatitis was successfully treated using the OTSC system, avoiding the need for an open procedure.

Abstract
Endoscopic biliary stenting is a useful way to treat distal malignant biliary strictures that are not eligible for surgery. A 10-Fr plastic or metal stent is used for stenting. Typically, endoscopic sphincterotomy (EST) has often been carried out as a way to prevent pancreatitis after stent placement given the ease of stent insertion, but EST has flaws such as bleeding and stent migration.The present study describes the need for EST prior to stent placement.

Abstract
Recently, the progress of endoscopy has made it possible to evaluate bile duct mucosa by peroral cholangioscopy. Herein, we report a case of immunoglobulin G4-related sclerosing cholangitis accompanying autoimmune pancreatitis in a patient who improved with treatment by steroid therapy and endoscopic biliary stenting, and observed the bile duct mucosa by peroral cholangioscopy before and after treatment.

Abstract
Background and Aims. For distal malignant biliary obstruction in cases with short life expectancy, occlusion of plastic stents (PSs) does not usually occur before death, and the application of such a procedure is considered adequate from the viewpoint of cost-effectiveness. Methods and Setting. A new commercially available DLS with side holes, a conventional DLS, and, uncovered self-expanding metal stents (SEMSs) were retrospectively evaluated in patients with jaundice due to unresectable distal malignant biliary obstruction. Results. A total of 64 patients received endoscopic biliary stenting (23 patients with the new DLS, 24 patients with conventional DLS, and 17 patients with uncovered SEMS) from December 2002 to August 2009. Median patency time was found to be 198 days for the new DLS group and 99 days for the conventional DLS group, revealing a significant difference between devices. There was, however, no significant difference in median patency time between the new DLS and the uncovered SEMS (198 days versus 344 days). Conclusion. The new DLS is efficient and safe and may be considered the first choice for unresectable distal malignant obstruction in cases with short life expectancy.
