World J Gastroenterol 2024; 30:2920-2922. [PMID: 38947285 PMCID: PMC11212719 DOI: 10.3748/wjg.v30.i22.2920] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 04/30/2024] [Accepted: 05/20/2024] [Indexed: 06/05/2024] Open
Abstract
Percutaneous ultrasound has been a longstanding method in the diagnostics and interventional procedures of liver diseases. In some countries, its use is restricted to radiologists, limiting access for other clinicians, such as gastroenterologists. Endoscopic ultrasound, as a novel technique, plays a crucial role in diagnosis and treatment of digestive diseases. However, its use is sometimes recommended for conditions where no clear advantage over percutaneous ultrasound exists, leaving the impression that clinicians sometimes resort to an endoscopic approach due to the unavailability of percutaneous options.

World J Gastroenterol 2024; 30:742-758. [PMID: 38515947 PMCID: PMC10950627 DOI: 10.3748/wjg.v30.i7.742] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 12/19/2023] [Accepted: 01/16/2024] [Indexed: 02/21/2024] Open
Abstract
BACKGROUND In hepatology, the clinical use of endoscopic ultrasound (EUS) has experienced a notable increase in recent times. These applications range from the diagnosis to the treatment of various liver diseases. Therefore, this systematic review summarizes the evidence for the diagnostic and therapeutic roles of EUS in liver diseases.
AIM To examine and summarize the current available evidence of the possible roles of the EUS in making a suitable diagnosis in liver diseases as well as the therapeutic accuracy and efficacy.
METHODS PubMed, Medline, Cochrane Library, Web of Science, and Google Scholar databases were extensively searched until October 2023. The methodological quality of the eligible articles was assessed using the Newcastle-Ottawa scale or Cochrane Risk of Bias tool. In addition, statistical analyses were performed using the Comprehensive Meta-Analysis software.
RESULTS Overall, 45 articles on EUS were included (28 on diagnostic role and 17 on therapeutic role). Pooled analysis demonstrated that EUS diagnostic tests had an accuracy of 92.4% for focal liver lesions (FLL) and 96.6% for parenchymal liver diseases. EUS-guided liver biopsies with either fine needle aspiration or fine needle biopsy had low complication rates when sampling FLL and parenchymal liver diseases (3.1% and 8.7%, respectively). Analysis of data from four studies showed that EUS-guided liver abscess had high clinical (90.7%) and technical success (90.7%) without significant complications. Similarly, EUS-guided interventions for the treatment of gastric varices (GV) have high technical success (98%) and GV obliteration rate (84%) with few complications (15%) and rebleeding events (17%).
CONCLUSION EUS in liver diseases is a promising technique with the potential to be considered a first-line therapeutic and diagnostic option in selected cases.

Abstract
In recent years, the incidence of chronic pancreatitis has increased significantly. Pancreatic calculi obstruct the pancreatic duct and induce abdominal pain in the patients. Pancreatic duct stenting is the major treatment option for chronic pancreatitis with calculi. In this study, a new kind of drug-eluting stent, a pancreatic stent coated by methacrylated gelatin (GelMA) hydrogel loaded with citric acid (CA), was designed for the interventional treatment of pancreatic duct calculi. The CA loading capacity reached up to 0.7 g CA/g hydrogel-coated stent. The GelMA hydrogel coating has higher mechanical strength and lower swelling performance after loading with CA. The in vitro experiments of stents exhibited good performance in CA sustained release and the calculi can be dissolved in almost 3 days. The stents also showed good blood compatibility and cell compatibility. This research has important clinical value in the treatment of chronic pancreatitis with pancreatic calculi.

Abstract
Non-invasive and high spatiotemporal resolution mythologies for the diagnosis and treatment of disease in clinical medicine promote the development of modern medicine. Ultrasound (US) technology provides a non-invasive, real-time, and cost-effective clinical imaging modality, which plays a significant role in chemical synthesis and clinical translation, especially in in vivo imaging and cancer therapy. On the one hand, the US treatment is usually accompanied by cavitation, leading to high temperature and pressure, so-called "hot spot", playing a significant role in sonochemical-based colloidal synthesis. Compared with the classical nucleation synthetic method, the sonochemical synthesis strategy presents high efficiency for the fabrication of colloidal nanocrystals due to its fast nucleation and growth procedure. On the other hand, the US is attractive for in vivo and medical treatment, with applications increasing with the development of novel contrast agents, such as the micro and nano bubbles, which are widely used in neuromodulation, with which the US can breach the blood-brain barrier temporarily and safely, opening a new door to neuromodulation and therapy. In terms of cancer treatment, sonodynamic therapy and US-assisted synergetic therapy show great effects against cancer and sonodynamic immunotherapy present unparalleled potentiality compared with other synergetic therapies. Further development of ultrasound technology can revolutionize both chemical synthesis and clinical translation by improving efficiency, precision, and accessibility while reducing environmental impact and enhancing patient care. In this paper, we review the US-assisted sonochemical synthesis and biological applications, to promote the next generation US technology-assisted applications.

Abstract
BACKGROUND/AIMS Endoscopic ultrasound gallbladder drainage (EUS-GBD) is gaining attention as a treatment method for cholecystitis. However, only a few studies have assessed the outcomes of permanent stenting with EUS-GBD. Therefore, we evaluated the clinical outcomes of permanent stenting using EUS-GBD. METHODS This was a retrospective, single-center cohort study. The criteria for EUS-GBD at our institution are a high risk for surgery, inability to perform surgery owing to poor performance status, and inability to obtain consent for emergency surgery. EUS-GBD was performed using a 7-Fr double-pigtail plastic stent with a dilating device. The primary outcomes were the recurrence-free rate of cholecystitis and the late-stage complication-avoidance rate. Secondary outcomes were technical success, clinical success, and procedural adverse events. RESULTS A total of 41 patients were included in the analysis. The median follow-up period was 168 (range, 10-1,238) days. The recurrence-free and late-stage complication-avoidance rates during the follow-up period were 95% (38 cases) and 90% (36 cases), respectively. There were only two cases of cholecystitis recurrence during the study period. CONCLUSION EUS-GBD using double-pigtail plastic stent was safe and effective with few complications, even in the long term, in patients with acute cholecystitis.

Effect of wet-heparinized suction on the quality of mediastinal solid tumor specimens obtained by endoscopic ultrasound-guided fine-needle aspiration: a retrospective study from a single center. BMC Gastroenterol 2023; 23:208. [PMID: 37316772 DOI: 10.1186/s12876-023-02845-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 06/04/2023] [Indexed: 06/16/2023] Open
Abstract
BACKGROUND Mediastinal lesions are diagnosed sometimes by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). Wet-heparinized suction technique has been used to improve the quality of abdominal solid tumor samples obtained by EUS-FNA. The aim of the study is to assess the effect of wet-heparinized suction on the quality of mediastinal solid tumor samples and to evaluate the safety of the method. METHODS The medical records, EUS-FNA records, pathologic data, and follow-up data between the patients who suspected mediastinal lesions with wet-heparinized suction and conventional suction were retrospectively and comparatively analyzed. Adverse events at 48 h and 1 week after EUS-FNA were evaluated. RESULTS Wet-heparinized suction contributed to more tissue specimens (P < 0.05), superior tissue integrity (P < 0.05), and a longer length of white tissue core (P < 0.05). In addition, the more complete the tissue bar was, the higher the rate of successful sample (P < 0.05). Moreover, the total length of the white tissue bar at the first puncture was remarkably longer in the Experimental group (P < 0.05). No significant difference in red blood cell contamination in paraffin sections was found between the two groups (P > 0.05). There was no complication after discharge in both groups. CONCLUSION Wet-heparinized suction can improve the quality of mediastinal lesion samples obtained by EUS-FNA and increase the success rate of sampling. In addition, it will not aggravate blood contamination in paraffin sections while ensuring a safe puncture.

Abstract
Background and Objectives EUS-guided biliary drainage (EUS-BD) required a dedicated training. We developed and evaluated a nonfluoroscopic, all-artificial training model known as Thai Association for Gastrointestinal Endoscopy Model 2 (TAGE-2) for the training of EUS-guided hepaticogastrostomy (EUS-HGS) and EUS-guided choledochoduodenostomy (EUS-CDS). We hypothesize that trainers and trainees would appreciate the ease of the nonfluoroscopy model and increase their confidence to start their real procedures in humans. Materials and Methods We prospectively evaluated the TAGE-2 launched in two international EUS hands-on workshops and have followed trainees for 3 years to see long-term outcomes. After completing the training procedure, the participants answered questionnaires to assess their immediate satisfaction of the models in and also the impact of these models on their clinical practice 3 years after the workshop. Results A total of 28 participants used the EUS-HGS model and 45 participants used the EUS-CDS model. The EUS-HGS model was rated as excellent by 60% of beginners and 40% by experienced and the EUS-CDS model was rated as excellent by 62.5% of beginners and 57.2% of experienced. The majority of trainees (85.7%) have started the EUS-BD procedure in humans without additional training in other models. Conclusion Our nonfluoroscopic, all-artificial model for EUS-BD training is convenient to be used with good-to-excellent satisfaction scored by the participants in most aspects. It can help the majority of trainees start their procedures in humans without additional training in other models.

Abstract
Surgeons have a role in observing, detect abnormalities, disease, and other deficiencies in function which could be treated. Diagnosing and treating back days were challenging for many reasons. However, technology's innovation enhances surgeons' ability to treat their patients. The term endoscopy refers to the Greek prefix endo- ("within") and the verb skopein ("to view or observe"). Endoscopy is practical both in the diagnosis and treatment of various pathologies. Technological advances, especially in endoscopy, gradually progress and discover many possibilities which allow rapid advancement. Endoscopy development aims to assess human orifice that has not been inspected, probed, and examined over the centuries. Endoscopy over these decades is improving, which led to new problem solving using advanced technological approaches. Thus, a surgeon can solve any issues from examination, diagnosis, and treatment using progressive endoscopy evolution. This review delivers a brief history of advances in surgical endoscopy and describes current endoscopy development.

Abstract
Chronic liver disease is still a major problem because disease progression will ultimately lead to liver cirrhosis. Portal hypertension is the hallmark in advanced liver disease management. By establishing portal vein access, endoscopic ultrasound (EUS) has been utilized in various clinical applications. In comparison to standard upper gastrointestinal endoscopy, EUS-Doppler has been shown to be a better modality for detecting esophageal and gastric varices along with peri-esophageal collateral veins, para-esophageal collateral veins, and perforating veins, and may be used to objectively predict the recurrence of bleeding. EUS-guided portal vein catheterization has also been proposed to overcome the limitations of trans-jugular approaches. The combination of EUS-elastography and azygos vein evaluation can also enhance the diagnostic accuracy of each modality. Another well-known implementation of EUS-guided procedures is in the management of ascites; particularly in paracentesis and ascitic fluid analysis. In addition, the most common clinical application of EUS in the treatment of portal hypertension is through vascular therapy or creation of intrahepatic portosystemic shunts. Major drawbacks of EUS mainly revolve around technical difficulties, the high cost of the procedure, as well as the requirement of more studies in humans to evaluate EUS-guided advanced therapeutic modalities in portal hypertension.

Abstract
Chronic liver disease (CLD) is still a major problem, where the disease progression will lead to liver cirrhosis (LC) or hepatocellular carcinoma (HCC). Portal hypertension (PH) management and loco-regional therapy for HCC have become the cornerstones in advanced liver disease management. Recently, there are studies looking at the potential role of interventional endoscopic ultrasound (EUS) in liver diseases. EUS may be useful in vascular changes of the digestive wall evaluation, performing dynamic assessment of hemodynamic changes, predicting variceal bleeding and rebleeding risk, and assessing the pharmacological effects. In PH management, EUS-guided vascular therapy-which revolves around glue injection, endovascular coil placement/embolization, and combination of both-has shown promising results. As a diagnostic modality for liver cancer, the implementation of EUS in liver diseases is currently not only limited to liver biopsy (EUS-LB) but also in shear-wave elastography (SWE) and portal pressure gradient measurement, as well as portal vein sampling. The application of EUS-guided radiofrequency ablation (EUS-RFA) and tumor injection can also overcome the limitations shown by both modalities without EUS. Nevertheless, establishing EUS as a firm diagnostic and therapeutic modality is still challenging since the performance of interventional EUS requires high expertise and adequate facilities.

BACKGROUND AND AIMS A potential method to reduce gastrointestinal toxicity during radiation therapy in pancreatic head cancer is to create a physical space between the head of the pancreas (HOP) and the duodenum. To date, there have been early reports on the feasibility of endoscopic ultrasound (EUS)-guided hydrogel injection into the interface between the HOP and the duodenum to increase the peri-pancreatic space for radiotherapy. We aimed to evaluate the technical feasibility of EUS-guided hydrogel injection for the creation of space at the peri-pancreatic interface in a cadaveric model. METHODS Baseline abdominal computerized tomography (CT) was performed on three unfixed cadaveric specimens. The hydrogel was injected transduodenally into the interface between the HOP and duodenum using linear-array EUS and a 19G needle for fine needle aspiration (FNA). This procedure was repeated along the length of the HOP. CT imaging and gross dissection were performed after the procedure to confirm the localization of the hydrogel and to measure the distance between the HOP and the duodenum. RESULTS All cadavers underwent successful EUS-guided injection of the hydrogel. Cadavers 1, 2, and 3 were injected with 9.5, 27, and 10 cc of hydrogel, respectively; along the HOP, the formation of the peri-pancreatic space was a maximum size of 11.77, 13.20, and 12.89 mm, respectively. The hydrogel injections were clearly visualized as hyperechoic bullae during EUS and on post-procedure CT images without any artifacts in all cases. CONCLUSIONS We demonstrated that EUS-guided delivery of hydrogel is feasible, and that it increases the peri-pancreatic space in a cadaveric model. The polyethylene glycol (PEG) hydrogel was clearly visible on EUS and CT, without significant artifacts. This may lead to new treatment approaches for pancreatic carcinomas.

Abstract
OBJECTIVES In patients with surgically altered anatomy, endoscopic treatment of pancreatic diseases is technically challenging. We aimed to evaluate the feasibility, effectiveness, and safety of an interchangeable combination of double-balloon endoscope-assisted ERP (DB-ERP) and endoscopic ultrasonography-guided pancreatic duct drainage (EUS-PD) in this clinical setting. METHODS Consecutive patients with surgically altered anatomy undergoing endoscopic treatment (DB-ERP, EUS-PD, or both) for pancreatic diseases were studied. The primary outcome was technical success; secondary outcomes were clinical success and adverse events. RESULTS Forty patients who underwent DB-ERP (38) and EUS-PD (2) as an initial intervention were retrospectively studied. Indications for intervention included 18 pancreaticojejunostomy anastomotic stricture (PJAS), four pancreatic duct stone (PDS), four pancreatic fistula (PF), 11 PJAS with PDS, and three PJAS with PF. Prior surgical reconstruction was 26 Billroth-II, 13 Roux-en-Y, and one Imanaga reconstruction. Along with salvage procedures including three DB-ERP and seven EUS-PD, the overall technical success rates of DB-ERP and EUS-PD were 70.7% (29/41) and 100% (9/9), respectively. Clinical success was achieved in 85.0% (34/40) by combination of DB-ERP and EUS-PD; successful drainage for PJAS, complete removal of PDS, and resolution of PF were achieved in 90.6%, 80.0%, and 71.4%, respectively. Adverse event rates were 12.2% (5/41; one perforation, and four pancreatitis) in DB-ERP and 55.6% (5/9; three pancreatic leakage, and two abdominal pain) in EUS-PD. CONCLUSIONS A combination of DB-ERP and EUS-PD can achieve high technical and clinical success for pancreatic diseases in surgically altered anatomy patients. A prospective multicenter study to investigate an appropriate treatment algorithm is warranted.

Abstract
BACKGROUND AND AIM Lumen-apposing metal stent is widely used for endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) nowadays but not approved in many countries and might be unsuitable for elective laparoscopic cholecystectomy (LC) because of its large enterocholecysto fistula. A combination of double pigtail plastic stent (DPPS) and naso-cystic tube (NCT) could overcome these problems. The aim of this study was to estimate the efficacy and safety of this method in patients with acute cholecystitis unfit for urgent cholecystectomy both as bridge to surgery and palliation. METHODS This was a prospective, single-center feasibility study. EUS-GBD was performed with a 7Fr DPPS followed by an NCT placement. NCT was removed after 1 week. LC was performed 2 or 3 months after EUS-GBD in eligible patients. In patients who did not underwent cholecystectomy, DPPS was left in place. RESULTS Twenty-three patients were enrolled. Both technical and clinical success rates were 96% (22/23). Early adverse events rate was 13% (3/23), including one bile peritonitis, one intraperitoneal abscess, and one melena. LC was attempted in 12 patients, and conversion to open cholecystectomy was required in three (25%). Neither recurrence of cholecystitis nor late adverse event occurred during 6 months of follow up in 10 patients who did not undergo cholecystectomy. CONCLUSION EUS-GBD with a combination of DPPS and NCT is considered an effective and safe technique both as bridge to surgery and palliation.

Abstract
Background and Objectives: EUS-FNA is applied widely in clinical practice, but there remains a lack of authentic training models. The present study aimed to develop a novel swine training model and to perform a preliminary assessment of its feasibility and efficacy. Materials and Methods: To create an internal lesion-like target, empty shells of iodine-125 seeds were implanted into the caudate lobe of the liver in Bama minipigs. A training program involving 10 trainees was subsequently carried out, in which a total of 60 needlings were performed, composed of 6 for each trainee obtained during two training steps. Comparisons of procedure-related variables were conducted between the two. Trainees completed a questionnaire to assess their basic endoscopic experiences and reasonability of the model. Results: A target region of 2.0 cm × 2.0 cm in diameter was successfully established on the caudate lobe in all implanted pigs. In the training program, the average procedure time decreased from the first to the second step and the average time for the total 30 needlings' obtainment was significantly shorter for the second training step (23.8 ± 4.5 min vs. 40.9 ± 9.0 min, P < 0.001). For the second step, there was also a significant improvement in total success rate (86.7% vs. 56.7%, P = 0.020) and accuracy rate (76.7% vs. 43.3%, P = 0.017). All trainees scored the effectiveness of the model highly and all reported improved confidence after the training. Conclusion: This novel swine training model could authentically mimic clinical EUS-FNA, providing an effective in vivo practice tool for novices before clinical practice.

Abstract
Endoscopic ultrasound (EUS) is among the most important tools for the evaluation of gastrointestinal tumors and affected areas around the gastrointestinal tract. It enables the acquisition of material from abnormal lesions via the gastrointestinal wall for tissue confirmation via endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). EUS-FNA has played a vital role in oncological care and has become the standard method for tissue sampling. The choice of needle type is an important factor determining tissue acquisition and has been evaluated by many researchers. New needles are introduced into the market almost every year, and opinions vary regarding proper needle selection. While there are diverse opinions but no definitive recommendations about the use of one particular device, fine-needle biopsy needles may provide detailed information on a tissue’s architecture based on greater sample yields. This permits additional analyses, including genetic sequencing and phenotyping, thereby enabling the provision of more personalized treatment plans. Furthermore, other EUS-guided procedures have been developed, including interventional EUS and through-the-needle devices. Given the continued attempts to improve the diagnostic ability and therapeutic techniques, we review in detail the available types of puncture needles to provide guidance on the selection of the appropriate needle types.

Abstract
Endoscopic injection of glues, clotting factors, or sclerosing agents is a well-known therapy for the treatment of non-variceal upper gastrointestinal bleeding (NVUGIB), but less is known about endoscopic ultrasound (EUS)-guided treatments. In this setting, literature data are scarce, and no randomized controlled trials are available. We performed a review of the existing literature in order to evaluate the role of EUS-guided therapies in the management of NVUGIB. The most common treated lesions were Dieulafoy's lesions, pancreatic pseudoaneurysms, and gastrointestinal stromal tumors (GISTs). Mostly, the treatments were performed as a salvage option after failure of conventional endoscopic hemostatic attempts, showing good efficacy and a good safety profile, also documented by Doppler monitoring of treated lesions. EUS-guided therapies may be an effective option in the treatment of refractory NVUGIB, thus avoiding radiological or surgical management. Nevertheless, available literature still lacks robust data.

Abstract
The development of endoscopic treatment for pancreatobiliary diseases in recent years is remarkable. In addition to conventional transpapillary treatments under endoscopic retrograde cholangiopancreatography (ERCP), new endoscopic ultrasound-guided therapy is being developed and implemented. On the other hand, due to the development/improvement of various devices such as new metal stents, a new therapeutic strategy under ERCP is also advocated. The present review focuses on recent advances in the endoscopic treatment of pancreatic pseudocysts, walled-off necrosis, malignant biliary strictures, and benign biliary/pancreatic duct strictures.

Abstract
Background and study aims During endoscopic ultrasound (EUS), patients may experience severe discomfort. The radial echoendoscope has a balloon around its tip. Balloon inflation prior to insertion may reduce contact injury and pharyngeal pain. The purpose of this study was to investigate the effect of balloon inflation on pharyngeal pain during insertion. Patients and methods Patients who underwent radial EUS for pancreatobiliary disease were randomized into standard insertion or balloon-inflated insertion. The primary outcome was the proportion of moderate-to-severe pharyngeal pain. Secondary outcomes were the degree of pharyngeal pain, risk factors for moderate pharyngeal pain, procedure-related adverse events, and pharyngeal pain depending on the experience of the endoscopist. Results A total of 481 patients were randomized into two groups: standard insertion (238) and balloon inflation (243). No statistically significant differences in proportion of moderate-to-severe pain were found (26.5 % vs. 20.2 %, P = 0.107). Balloon inflation (HR 0.65; 95 % CI (0.42-0.98, P = 0.041) was a protective factor against moderate pain. Balloon inflation reduced the proportion of patients with moderate-to-severe pain when performed by physicians with less than 3months of experience with EUS (44.7 % vs. 25.3 %, P = 0.012). Conclusion Balloon inflation did not reduce the absolute degree of post-procedural pain with EUS, but it reduced the number of patients with moderate-to-severe pain when performed by physicians with less than 3 months of experience.

Abstract
BACKGROUND AND AIMS Cholelithiasis is the most common biliary tract disorder. Surgery is the treatment of choice for symptomatic gallstones. Aims of this study were to investigate the feasibility and short-term safety of a new endoscopic procedure with a specially designed Nitinol gallbladder stent for blockage of gallstone migration, the Shai™ Stent. The Shai stent is designed to enable free bile flow, which will be supposed to prevent recurrent attacks. METHODS The Shai™ Stent was inserted into the gallbladder during a standard ERCP procedure using a conventional metal stent delivery system. The aim of the present study was to investigate the feasibility and safety of insertion and deployment and removal of the stent into the gallbladder of pigs. In addition, the short-term safety of the stent was evaluated. RESULTS Fifteen stents were placed in the gallbladder of 15 pigs. Mean procedure time was 25 min (15-37). The maximum follow-up before sacrifice was 42 days. The stent in 1 pig had migrated at the 42 days follow-up but there were no macroscopic changes in its gallbladder or other organs. The stent remained in place in the remaining 12 pigs at autopsy, and the gallbladder and bile ducts were macroscopically normal. Stent removal was easily done in two pigs immediately after placement. CONCLUSIONS Correct placement and removal of the Shai™ Stent in the gallbladder is safe and feasible in pigs. Further clinical trials are warranted to confirm these results and to effectively evaluate the capability of this stent as an innovative biotechnology to block gallstones from migration and impaction.

Abstract
Although endoscopic retrograde cholangiopancreatography (ERCP) is the first-line treatment for benign biliary diseases, this procedure is technically difficult in some conditions such as a surgically altered anatomy and gastric outlet obstruction. After a failed ERCP, a surgical or a percutaneous approach is selected as a rescue procedure; however, various endoscopic ultrasound (EUS)-guided interventions are increasingly utilized in pancreatobiliary diseases, including EUS-guided rendezvous for failed biliary cannulation, EUS-guided antegrade treatment for stone management, and EUS-guided hepaticogastrostomy for anastomotic strictures in patients with a surgically altered anatomy. There are some technical hurdles in EUS-guided interventions for benign biliary diseases owing to the difficulty in puncturing a relatively small bile duct and in subsequent guidewire manipulation, as well as the lack of dedicated devices. A recent major advancement in this field is the introduction of a 2-step approach, in which EUS-guided drainage is placed in the first session and antegrade treatment is performed in subsequent sessions. This approach allows the use of various techniques such as mechanical lithotripsy and cholangioscopy without a risk of bile leak. In summary, EUS-guided interventions are among the treatment options for benign biliary diseases; however, standardization of the procedure and development of a treatment algorithm are needed.

Abstract
OBJECTIVES Percutaneous transhepatic gallbladder drainage (PTGBD) is widely used for patients with acute cholecystitis. There are little data on the efficacy and safety of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) replacement of PTGBD in patients who cannot undergo cholecystectomy. METHODS This multicenter retrospective study in Japan reviewed records of patients who underwent EUS-GBD to replace PTGBD between January 2010 and December 2017. Outcomes evaluated included technical success, defined as successful stent placement between the gastrointestinal lumen and the gallbladder; clinical success, defined as subsequent removal of the percutaneous catheter; adverse events; and stent patency. RESULTS EUS-GBD was performed in 21 patients (14 women, mean age 77.5 ± 8.0 years) to replace PTGBD that had been instituted for acute cholecystitis (n = 19) or obstructive jaundice (n = 2). Technical success was achieved in 19 (90.5%). The median period from PTGBD placement to EUS-GBD was 11 days (range, 6-68 days). The mean procedure time was 19.5 ± 5.1 min. No early adverse events were observed. There were three late adverse events, distal stent migration in two cases and stent occlusion causing recurrent cholecystitis in one patient. Reintervention was required in two patients. The percutaneous catheter was removed after EUS-GBD in 17 patients at a median of 7 days (range, 2-20 days). The duration of stent patency was 139 days (range, 8-664 days). CONCLUSIONS Where ongoing gallbladder drainage is required, conversion from PTGBD to EUS-GBD is a feasible, effective, and safe technique for patients who cannot undergo cholecystectomy.

Abstract
Endoscopic ultrasound-guided biliary drainage (EUS-BD) is increasingly used as an alternative in patients with biliary obstruction who fail standard endoscopic retrograde cholangiopancreatography (ERCP). The two major endoscopic approach routes for EUS-BD are the transgastric intrahepatic and the transduodenal extrahepatic approaches. Biliary drainage can be achieved by three different methods, transluminal biliary stenting, transpapillary rendezvous technique, and antegrade biliary stenting. Choice of approach route and drainage method depends on individual anatomy, underlying disease, and location of the biliary stricture. Recent meta-analyses have revealed that cumulative technical success and adverse event rates were 90-94% and 16-23%, respectively. Development of new dedicated devices for EUS-BD would help refine the technical aspects and minimize the possibility of complications, making it a more promising procedure.

Abstract
Heterotopic pancreas (HP) is a relatively uncommon entity that is defined as pancreatic tissue without a true anatomical or vascular connection to the pancreas. HP does not cause symptoms in most cases but can occasionally produce various manifestations, including nausea, vomiting, abdominal pain, and even heterotopic pancreatitis. Here, we report an unusual case in which heterotopic pancreatitis complicated by the formation of a pseudocyst that caused gastric outlet obstruction was diagnosed based on serum hyperamylasemia and findings from endoscopic ultrasonography (EUS)-guided fine needle aspiration (EUS-FNA) cytology. EUS-guided single pigtail stent insertion was successfully performed for recurrent gastric outlet obstruction. The patient has remained healthy and symptom-free during 4 years of surveillance. In the context of the relevant literature, the described case is a rare case of HP complicated by a pseudocyst treated via EUS-FNA and stent insertion.
