Abstract
Endoscopic ultrasound (EUS)-guided transhepatic biliary drainage is usually performed with a 19-gauge fine-needle aspiration (FNA) needle and a 0.025-inch guidewire. The combination of a 22-gauge FNA needle and a 0.018-inch guidewire is reported to be effective as a rescue option when the bile duct diameter is small or technically challenging. Experts in EUS-guided transhepatic biliary drainage have reported that bile duct puncture with a 19-gauge FNA needle is possible in most cases, but is not easy to reproduce by endoscopists with less experience in EUS-guided transhepatic biliary drainage. We investigated the usefulness of EUS-guided transhepatic biliary drainage using a 22-gauge FNA needle and a 0.018-inch guidewire during the procedure's induction phase. Consecutive patients who underwent EUS-guided transhepatic biliary drainage at our institution from March 2021 to May 2023 were evaluated, and 37 were included. Biliary drainage was performed for malignant bile duct stricture in 36 patients and choledocholithiasis in one patient. The median target bile duct diameter was 4.5 mm (2.5-9.4). Biliary access, fistula dilation, and stent placement were successful in the 37 patients (100%). The median procedure time was 35 min (16-125). Adverse events occurred in four (10.8%) patients. EUS-guided transhepatic biliary drainage using a 22-gauge FNA needle and a 0.018-inch guidewire is a useful and promising option for endoscopists with limited experience in EUS-guided transhepatic biliary drainage in the procedure's induction phase.

Abstract
Background and study aims In cases of inaccessible papilla, EUS-guided biliary drainage (EUS-BD) has been described as an alternative to calibrate benign biliary stenosis. However, few studies are available. Patients and methods This tw-center, retrospective study was designed to evaluate technical success and clinical success at 1 year. All patients who underswent EUS-BD without the rendezvous technique used for calibration of benign biliary stenosis were included from 2016 to 2022. Patients underwent EUS-hepaticogastrostomy (EUS-HGS) during the first session. Then, HGS was used to access the bile duct, allowing calibration of the stenosis: Dilation of the biliary stenosis and placement of double pigtail stents through the stenosis for 1 year. Results Thirty-six patients were included. Technical success was 89% (32/36), with four failures to cross the stenosis but EUS-HGS was performed in 100% of the cases. Nine patients were excluded during calibration because of oncological relapse in six and complex stenosis in three. Three patients had not yet reached 1 year of follow-up. Twenty patients had a calibration for at least 1 year. Clinical success after stent placement was considered in all cases after 1 year of follow-up. Thirteen patients underwent stent removal and no relapse occurred after 435 days of follow-up (SD=568). Global morbidity was 41.7% (15/36) with only one serious complication (needing intensive care), including seven cases of cholangitis due to intrabiliary duct obstruction and five stent migrations. No deaths were reported. Conclusions EUS-BD for calibration in case of benign biliary stenosis is an option. Dedicated materials are needed to decrease morbidity.

Abstract
Background and Aim Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is widely used in the management of biliary obstructions; however, literature on guidewire manipulation is lacking. This study aimed to assess the utility and optimal conditions of the loop technique for guidewire manipulation during EUS-HGS. Methods Consecutive patients who underwent EUS-HGS between April 2015 and January 2022 were included in this study. Patient characteristics and procedural details were retrospectively analyzed. Guidewire manipulations were classified as conventional technique or loop technique, based on the shape of the guidewire tip. Results A total of 52 patients (Median age: 73 years, 38 male and 14 female) underwent EUS-HGS. The median guidewire insertion time was 49 s and the median overall procedure time was 20.5 min. The initial guidewire direction was toward the peripheral side in 23 patients (44%). Technical success rate of the EUS-HGS was 100%. Twenty patients (38%) underwent the procedure using the loop technique and 32 (62%) with the conventional technique. In the logistic regression analysis, an angle between the bile duct and needle of >70° was independently associated with use of the loop technique (OR 9.84; 95% CI: 2.24-43.13; P <0.01). Conclusion This study revealed the utility of the loop technique in EUS-HGS. This technique is recommended if the bile duct is punctured at an angle >70°.

Abstract
BACKGROUND Recently, endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) procedures have been gradually established; nonetheless, some adverse events (AEs) have been reported. Dilation procedures using a non-cautery or cautery device increase the incidence of AEs in EUS-HGS. AIMS We evaluated EUS-HGS procedures without dilation and the factors associated with dilation. METHODS We enrolled 79 patients who underwent EUS-HGS between July 2015 and March 2021 at two centers, 72 of whom had technical success (72/79, 91%). During the EUS-HGS procedures, we defined patients without dilation procedures as the dilation (-) group. We divided the patients into two groups: the dilation (+) (35 patients) and dilation (-) (37 patients) groups. We performed a propensity score matching analysis to adjust for confounding bias between the two groups. Multivariable logistic regression analysis was conducted to identify factors associated with dilation. RESULTS There was no difference in clinical success rate between the dilation (+) and dilation (-) groups (91% vs. 95%, P = 0.545). The AE rate (P = 0.013) and long procedure time (P = 0.017) were significantly higher in the dilation (+) group than in the dilation (-) group before and after propensity score matching. Factors associated with dilation were plastic stent placement (odds ratio [OR], 6.96; 95% confidence interval [CI], 1.68-28.7; P = 0.007) and puncture angle of ≤ 90° (OR, 44.6; 95% CI, 5.1-390; P < 0.001). CONCLUSIONS A dilation procedure in EUS-HGS may not always be necessary. However, patients with an angle of ≤ 90° between the needle and intrahepatic biliary tract or plastic stent deployment require dilation procedures.

Abstract
Endoscopic Retrograde Cholangiopancreatography (ERCP), even in expert hands, may fail in 5-10% of cases, especially in cases of papillary infiltration, malignant gastric outlet obstruction, or surgically altered anatomy. Percutaneous transhepatic biliary drainage (PTBD) has represented the traditional rescue therapy, despite associated with high rate of adverse events, need for re-interventions and an inferior quality of life. The evolution of Endoscopic Ultrasound (EUS) from a diagnostic to a therapeutic tool offers an effective and safe alternative for internal biliary drainage (BD) into the stomach or the duodenum. EUS-BD is reported to have similar or even improved efficacy and increased safety when compared to PTBD and can be performed in the same session of a failed ERCP. This review summarizes technical aspects of intra-hepatic and extra-hepatic EUS-BD (including hepatico-gastrostomy, choledocho-duodenostomy and rendezvous) together with current evidence and future perspectives that steadily cements EUS-BD's place in multidisciplinary management of bilio-pancreatic diseases.

Abstract
BACKGROUND Since it was first described in 2001, endoscopic ultrasonography-guided biliary drainage (EUS-BD) has emerged as an alternative procedure for achieving an endoscopic internal drainage in case of endoscopic retrograde cholangiopancreatography (ERCP) failure. Biliary drainage can be achieved by either a transduodenal extrahepatic approach through EUS-guided choledochoduodenostomy (EUS-CDS), or a transgastric intrahepatic approach, namely EUS-guided hepaticogastrostomy (EUS-HGS) which already holds a remarkable place in the treatment of patients with malignant biliary obstruction. DATA SOURCES For this review we did a comprehensive search of PubMed/MEDLINE from inception to May 31, 2021 for papers with a significant sample size (at least 20 patients enrolled) dealing with EUS-HGS. Data on technical success, clinical success and rate of adverse events were collected. RESULTS A total of 22 studies with different design, comprising 874 patients, were included. Technical success was achieved in about 96% of cases (ranging from 65% to 100%). Clinical success was obtained in almost 91% of cases (ranging from 76% to 100%). Overall rate of adverse events was 19% (ranging from 0% to 35%). Abdominal pain, self-limiting pneumoperitoneum, bile leak, cholangitis, bleeding, perforation and intraperitoneal migration of the stent were the most common. CONCLUSIONS Despite both safety and efficacy profile, at the moment HGS still remains a challenging procedure at every single step and must therefore be conducted by a very experienced endoscopist in interventional EUS and ERCP procedures, who is able to deal with the possible severe adverse events of this procedure. A rapid introduction in clinical practice of dedicated devices is desiderable.

Abstract
Currently, endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is widely performed worldwide for various benign and malignant biliary diseases in cases of difficult or unsuccessful endoscopic transpapillary cholangiopancreatography (ERCP). Furthermore, its applicability as primary drainage has also been reported. Although recent advances in EUS systems and equipment have made EUS-HGS easier and safer, the risk of serious adverse events such as bile leak and stent migration still exists. Physicians and assistants need not only sufficient skills and experience in ERCP-related procedures and basic EUS-related procedures such as fine needle aspiration and pancreatic fluid collection drainage, but also knowledge and techniques specific to EUS-HGS. This technical review mainly focuses on EUS-HGS with self-expandable metal stents for unresectable malignant biliary obstruction and presents the latest and detailed tips for safe and successful performance of the technique.

Abstract
Background and study aims Stent migration into the abdominal cavity, which can occur due to stent shortening or stomach mobility, is a critical adverse event (AE) in EUS-HGS. To prevent this AE due to stent shortening, a novel, partially covered self-expandable metal stent with an antimigratory single flange has recently become available in Japan. The present study evaluated the clinical feasibility and safety of EUS-HGS using this novel stent. Patients and methods We measured stent length in the abdominal cavity and the luminal portion after EUS-HGS using computed tomography (CT) performed 1 day after EUS-HGS (early phase). To evaluate stent shortening and the influence of stomach mobility, we also measured stent length at the same sites on CT performed at least 7 days after EUS-HGS (late phase). Results Thirty-one patients successfully underwent EUS-HGS using this stent. According to CT in the early phase, stent length in the abdominal cavity was 7.13 ± 2.11 mm and the length of the luminal portion was 53.3 ± 6.27 mm. Conversely, according to CT in the late phase, stent length in the abdominal cavity was 8.55 ± 2.36 mm and the length of the luminal portion was 50.0 ± 8.36 mm. Stent shortening in the luminal portion was significantly greater in the late phase than in the early phase ( P = 0.04). Conclusions CT showed that stent migration can occur even with successful stent deployment, due to various factors such as stent shortening. The antimigratory single flange may be helpful to prevent stent migration, but further prospective comparative studies are needed to confirm our results.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the mainstay procedure of choice for management of obstructive biliary disease. While ERCP is widely performed with high success rates, the procedure is not feasible in every patient such as cases of non-accessible papilla. In the setting of unsuccessful ERCP, endoscopic ultrasound-guided biliary drainage (EUS-BD) has become a promising alternative to surgical bypass and percutaneous biliary drainage (PTBD). A variety of different forms of EUS-BD have been described, allowing for both intrahepatic and extrahepatic approaches. Recent studies have reported high success rates utilizing EUS-BD for both transpapillary and transluminal drainage, with fewer adverse events when compared to PTBD. Advancements in novel technologies designed specifically for EUS-BD have led to increased success rates as well as improved safety profile for the procedure. The techniques of EUS-BD are yet to be fully standardized and are currently performed by highly trained advanced endoscopists. The aim of our review is to highlight the different EUS-guided interventions for achieving biliary drainage and to both assess the progress that has been made in the field as well as consider what the future may hold.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the primary treatment modality for bile duct obstruction. When ERCP is unsuccessful, percutaneous transhepatic biliary drainage can be an alternative method. Endoscopic ultrasound-guided biliary drainage (EUS-BD) has emerged as a treatment option for biliary obstruction, especially after ERCP failure. EUS-BD offers transluminal intrahepatic and extrahepatic drainage through a transgastric and transduodenal approach. EUS-guided hepaticogastrostomy (EUS-HGS) is an excellent choice for patients with hilar strictures or those with a surgically altered anatomy. The optimal steps in EUS-HGS are case selection, bile duct visualization, puncture-site selection, wire insertion and manipulation, tract dilation, and stent placement. Caution should be taken at each step to prevent complications. Dedicated devices for EUS-HGS have been developed to improve the technical success rate and reduce complications. This technical review focuses on the essential practical points at each step of EUS-HGS.

Abstract
Endoscopic ultrasound-guided biliary drainage has been developed as an alternative method for biliary drainage. EUS-guided hepaticogastrostomy (EUS-HGS) can be attempted via the trans-gastric route. These procedures are technically complex for two reasons. First, puncture of the intrahepatic bile duct via the trans-gastric route can be more difficult than that by other approaches because of the small diameter of the target site, and guidewire insertion or manipulation is challenging during EUS-HGS. Second, critical adverse events, such as stent migration into the abdominal cavity, could occur because of the greater mobility of the stomach compared to the duodenum. Therefore, endoscopists should be cautious when performing EUS-HGS. An advantage of EUS-HGS is that it can be performed in patients with complications such as duodenal bulb obstruction or surgically altered anatomy. Recent advances in technique and improvements in devices and stents for EUS-HGS have shown promise for improving the technical success rate of EUS-HGS and reducing the rate of adverse events. However, endoscopists should remain aware of the possibility of critical adverse events such as stent migration.

Abstract
BACKGROUND With endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), guidewire manipulation might be a critically limiting step for nonexperts. However, the causes of difficult guidewire manipulation remain unclear. The aim of this study was to evaluate factors associated with successful guidewire manipulation. METHODS This retrospective cohort study included consecutive patients who underwent EUS-HGS between October 2018 and October 2019. We measured scope angle between the long and needle axes of the echoendoscope using still fluoroscopic imaging immediately after puncturing the intrahepatic bile duct. Factors associated with successful guidewire insertion were assessed by multivariable analysis using logistic regression. RESULT The influence of the angle between the fine-needle aspiration (FNA) needle and echoendoscope on failed guidewire insertion was assessed using receiver operating characteristic (ROC) curves. Area under the ROC curve was 0.86 (95 % confidence interval [CI] 0.00 - 0.76), and an angle of 135° offered 88.0 % sensitivity and 82.9 % specificity for predicting successful guidewire insertion. According to multivariable analysis, only angle between the FNA needle and echoendoscope > 135° was independently associated with successful guidewire insertion (odd ratio 0.03, 95 %CI 0.01 - 0.14; P < 0.05), whereas sex, puncture site, and diameter of puncture site were not significant factors. After multivariable analysis, all variables were adjusted using age ≥ 70 or < 70 years, yielding the same results. CONCLUSION The angle between the FNA needle and echoendoscope might be associated with successful guidewire manipulation during EUS-HGS. Adjusting this angle to 135° before puncturing the intrahepatic bile duct might be helpful in achieving successful guidewire manipulation during EUS-HGS.

Abstract
Most patients who require biliary drainage can be treated by endoscopic retrograde cholangiopancreatography (ERCP)-guided procedures. However, ERCP can be challenging in patients with complications, such as malignant duodenal obstruction, or a surgically-altered anatomy, such as a Roux-en-Y anastomosis, which prevent advancement of the duodenoscope into the ampulla of Vater. Recently, endoscopic ultrasound (EUS)-guided biliary drainage via transhepatic or transduodenal approaches has emerged as an alternative means of biliary drainage. Typically, EUS-guided gallbladder drainage or choledochoduodenostomy can be performed via both approaches, as can EUS-guided hepaticogastrostomy (HGS). EUS-HGS, because of its transgastric approach, can be performed in patients with malignant duodenal obstruction. Technical tips for EUS-HGS have reached maturity due to device and technical developments. Although the technical success rates of EUS-HGS are high, the rate of adverse events is not low, with stent migration still being reported despite many preventive efforts. In this review, we described technical tips for EUS-HGS related to bile duct puncture, guidewire insertion, fistula dilation, and stent deployment, along with a literature review. Additionally, we provided technical tips to improve the technical success of EUS-HGS.

Abstract
Background and study aims Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HGS) may be most complex because of the EUS-guided biliary drainage procedure and variations in the course of the intrahepatic bile duct compared with the common bile duct (CBD). Appropriate guidewire insertion is essential. Physician-controlled guidewire manipulation (PCGW) might improve technical success rates of bile duct cannulation. The present study aimed to determine the technical feasibility and safety of PCGW during EUS-HGS. Patients and methods A total of 122 consecutive patients who were scheduled to undergo EUS-HGS between October 2017 and April 2019 were prospectively registered. The primary endpoint was the technical success rate of guidewire insertion into the CBD or hepatic hilum. Guidewire insertion was considered to have failed if the HGS assistant failed to achieve manipulation. Results The intrahepatic bile duct was successfully punctured in 120 of 122 patients. During guidewire insertion by the HGS assistant, guidewire fracture was observed in one patient. The guidewire was successfully inserted into the biliary tract and manipulated by the HGS assistant in 96 patients. PCGW was thus attempted for the remaining 23 patients. The guidewire was inserted by PCGW in all 23 patients, improving the technical success rate for guidewire insertion from 80 % to 100 %. After tract dilation, we deployed covered metal stents and plastic stents in 117 and two patients, respectively. The overall technical success rate for EUS-HGS was 97.5 % (119/122). Adverse events comprising bile peritonitis or leakage developed in five patients. Conclusion PCGW might contribute to improving the success rate of EUS-HGS.

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
Endoscopic transpapillary or transanastomotic pancreatic duct drainage (PD) is the mainstay of drainage in symptomatic pancreatic duct obstruction or leakage. However, transpapillary or transanastomotic PD can be technically difficult due to the tight stricture or surgically altered anatomy (SAA), and endoscopic ultrasound (EUS)-guided PD (EUS-PD) is now increasingly used as an alternative technique. There are two approaches in EUS-PD: EUS-guided rendezvous (EUS-RV) and EUS-guided transmural drainage (EUS-TMD). In cases with normal anatomy, EUS-RV should be the first approach, whereas EUS-TMD can be selected in cases with SAA or duodenal obstruction. In our literature review, technical success and adverse event rates were 78.7% and 21.8%, respectively. The technical success rate of EUS-RV appeared lower than EUS-TMD due to the difficulty in guidewire passage. In future, development of dedicated devices and standardization of EUS-PD procedure are necessary.

Abstract
In 1980, endoscopic ultrasound (EUS) was introduced as a diagnostic tool for evaluation of the pancreas. Since the introduction of curvilinear-array echoendoscopy, EUS has been used for a variety of gastrointestinal interventions, including fine needle aspiration, tumor ablation, and pancreatobiliary access. One of the main therapeutic roles of EUS is biliary drainage as an alternative to endoscopic retrograde biliary drainage (ERBD) or percutaneous transhepatic biliary drainage (PTBD). This article summarizes three different methods of EUS-guided biliary access, with focus on technique and practical tips.

Abstract
BACKGROUND AND AIM On endoscopic ultrasound (EUS)-guided biliary drainage, fistula dilation may be accompanied by leakage of bile juice, potentially along with bacteria or air, so this procedure should be kept as simple and short as possible. To date, various techniques to dilate the fistula have been reported. This prospective, single-center, single-arm study evaluated the technical feasibility and safety of EUS-guided biliary drainage using novel balloon catheters. METHODS Tip of novel balloon catheters is only 3 Fr and tapered, and the catheters also show favorable push ability. First, biliary tract was punctured using 19-G fine needle aspiration needle. Next, we immediately inserted the novel balloon catheter, and the biliary tract and intestinal wall were dilated. Then, we performed metallic stent placement without any dilation fistula. RESULTS A total of 20 patients were prospectively enrolled in this study. Technical success rate was 100%. Eleven patients underwent EUS-guided choledochoduodenostomy, and nine patients underwent EUS-guided hepaticogastrostomy. Median procedure time was only 11 min (range, 8-16 min) for EUS-guided choledochoduodenostomy and 14 min (range, 11-18 min) for EUS-guided hepaticogastrostomy. Adverse events were seen in 15% (3/20; self-limited abdominal pain n = 2, peritonitis n = 1). CONCLUSIONS Although additional cases and a randomized controlled comparison with another dilation technique such as the graded dilation or cystotome dilation technique are needed, our technique may be helpful for EUS-guided biliary drainage.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the gold-standard modality for diagnosis and therapy of bilio-pancreatic disease. In particular, peroral cholangiography (POCS) is a useful modality not only for diagnosing biliary disease, but also for therapeutic procedures such as electrohydraulic lithotripsy. The SPY-DS single-operator cholangioscope has recently become available, and offers favorable visualization, a wide view, suction function and a larger accessory working channel. However, if the duodenoscope cannot be advanced into the ampulla of Vater for reasons such as surgical anatomy, POCS cannot be performed. On the other hand, percutaneous transhepatic cholangiodrainage (PTCD) has been developed as an alternative endoscopic ultrasound-guided approach to the biliary tract. Peroral transluminal cholangioscopy (PTLC) using SPY-DS is a novel approach. Because transluminal interventional procedures under endoscopic ultrasound guidance have recently been developed, our technique may have clinical impact for selected cases.
