Adrenal gland infection is a clinical entity of great importance, but it is a largely unrecognized pathology. Immunosuppressed individuals are at a higher risk of presentation. Herein, we describe a young female patient, recently diagnosed with HIV, who presented with severe sepsis due to methicillin-resistant Staphylococcus aureus, associated with a left adrenal abscess. She was initially treated with antibiotics; however, due to the persistence of the systemic inflammatory response and bacteremia, endoscopic ultrasound-guided drainage was performed. This procedure was successful in resolving the clinical situation. Endoscopic ultrasound-guided adrenal gland drainage can be a safe, efficacious, and minimally invasive option for managing antibiotic-refractory adrenal abscesses in immunosuppressed patients.

Advanced malignant hilar biliary obstruction (MHBO) with inaccessible papilla poses a significant challenge to endoscopists, as drainage of multiple liver segments may be warranted. Transpapillary drainage may not be feasible in patients with surgically altered anatomy, duodenal stenosis, prior duodenal self-expanding metal stent, and after initial transpapillary drainage, but require re-intervention for draining separated liver segments. Endoscopic ultrasound-guided biliary drainage (EUS-BD) and percutaneous trans-hepatic biliary drainage are the feasible options in this scenario. The major advantages of EUS-BD over percutaneous trans-hepatic biliary drainage include a reduction in patient discomfort and internal drainage away from the tumor, thus reducing the possibility of tissue or tumor ingrowth. With innovations, EUS-BD is helpful not only for bilateral communicating MHBO but also for non-communicating systems with bridging hilar stents or isolated right intra-hepatic duct drainage by hepatico-duodenostomy. EUS-guided multi-stent drainage with specially designed cannulas and guidewires has become a reality. A combined approach with endoscopic retrograde cholangiopancreatography for re-intervention, interventional radiology, and intraductal tumor ablative therapies has been reported. Stent migration and bile leakage can be minimized with proper stent selection and technique, and stent blocks can be managed with EUS-guided interventions in a majority of cases. Future comparative studies are required to establish the role of EUS-guided interventions in MHBO as rescue or primary therapy.

The incidence of acute pancreatitis (AP) has increased in the pediatric population over the past few decades and it stands to follow that the complications of severe AP, including symptomatic pancreatic fluid collections (PFCs) will increase as well. In adults, the therapeutic options for this situation have undergone a dramatic evolution from mainly surgical approaches to less invasive endoscopic approaches, mainly endoscopic ultrasound-guided transmural drainage (EUS-TD) followed be direct endoscopic necrosectomy if needed. This has proven safe and effective in adults; however, this approach has not been well studied or reported in pediatric populations. Here we demonstrate that EUS-TD seems to offer a safe, efficacious and minimally invasive approach to the management of large PFCs in pediatric patients by reviewing two representative cases at our institution.

Endoscopic ultrasound (EUS)-guided interventions have evolved rapidly in recent years, with dedicated metal stents playing a crucial role in this process. Specifically, the invention of biflanged short metal-covered stents, including lumen-apposing metal stents (LAMS), and modifications in a variety of tubular self-expandable metal stents (SEMS), have led to innovations in EUS-guided interventions. LAMS or non-LAMS stents are commonly used in the EUS-guided drainage of pancreatic fluid collections, especially in cases of walled-off necrosis. Additionally, LAMS is commonly considered for drainage of the EUS-guided gallbladder or dilated common bile duct and EUS-guided gastroenterostomy. Fully or partially covered tubular SEMS with several new designs are being considered for EUS-guided biliary drainage. This review focuses on advances in SEMS for EUS-guided interventions and discusses related research results.

Technical failure of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is often attributed to device failure. To rectify this problem, we developed a single-pigtail plastic stent (SPPS) for EUS-GBD. We retrospectively reviewed the cases of four patients who underwent EUS-GBD for acute cholecystitis. To prepare the SPPS, a 7.5-Fr endoscopic nasobiliary drainage tube was cut to an appropriate length. The use of SPPS during EUS-GBD was successful from both technical and clinical standpoints. The SPPS spontaneously detached 57 days after the procedure in patient 4 and 412 days after the procedure in patient 1. Patient 1 developed cholecystitis after 426 days and was managed with antibiotics. The other three patients did not develop any complications after surgery. In conclusion, we designed a new SPPS dedicated to EUS-GBD and established its technical feasibility and clinical effectiveness.

Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) through ducts B2 or B3 is effective in most patients with biliary obstruction, because B2 and B3 commonly join together. However, in some patients, B2 and B3 do not join each other due to invasive hilar tumors; therefore, single-route drainage is insufficient. Here, we investigated the feasibility and efficacy of EUS-HGS through both B2 and B3 simultaneously in seven patients. We decided to perform EUS-HGS through both B2 and B3 to achieve adequate biliary drainage because these two ducts were separate from each other. Here, we report a 100% technical and overall clinical success rate. Early adverse effects were closely monitored. Minimal bleeding was reported in one patient (1/7) and mild peritonitis in one patient (1/7). None of the patients experienced stent dysfunction, fever, or bile leakage after the procedure. EUS-HGS through both B2 and B3 simultaneously is safe, feasible, and effective for biliary drainage in patients with separated ducts.

Background/Aims: Endoscopic ultrasound (EUS) has become an essential diagnostic and therapeutic tool. EUS was introduced in 2013 in Indonesia and is considered relatively new. This study aimed to describe the current role of interventional EUS at our hospital as a part of the Indonesian tertiary health center experience. Methods: This retrospective study included all patients who underwent interventional EUS (n=94) at our center between January 2015 and December 2020. Patient characteristics, technical success, clinical success, and adverse events associated with each type of interventional EUS procedure were evaluated. Results: Altogether, 94 interventional EUS procedures were performed at our center between 2015 and 2020 including 75 cases of EUS-guided biliary drainage (EUS-BD), 14 cases of EUS-guided pancreatic fluid drainage, and 5 cases of EUS-guided celiac plexus neurolysis. The technical and clinical success rates of EUS-BD were 98.6% and 52%, respectively. The technical success rate was 100% for both EUS-guided pancreatic fluid drainage and EUS-guided celiac plexus neurolysis. The adverse event rates were 10.6% and 7.1% for EUS-BD and EUS-guided pancreatic fluid drainage, respectively. Conclusions: EUS is an effective and safe tool for the treatment of gastrointestinal and biliary diseases. It has a low rate of adverse events, even in developing countries.

Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HGS) is widely performed not only as an alternative to transpapillary biliary drainage, but also as primary drainage for malignant biliary obstruction. For anatomical reasons, this technique carries an unavoidable risk of mispuncturing intrahepatic vessels. We report a technique for troubleshooting EUS-guided portal vein coiling to prevent bleeding from the intrahepatic portal vein after mispuncture during interventional EUS. EUS-HGS was planned for a 59-year-old male patient with unresectable pancreatic cancer. The dilated bile duct (lumen diameter, 2.8 mm) was punctured with a 19-gauge needle, and a guidewire was inserted. After bougie dilation, the guidewire was found to be inside the intrahepatic portal vein. Embolizing coils were placed to prevent bleeding. Embolization coils were successfully inserted under stabilization of the catheter using a double-lumen cannula with a guidewire. Following these procedures, the patient was asymptomatic. Computed tomography performed the next day revealed no complications.

Benign biliary stricture (BBS) is a complication of chronic pancreatitis (CP). Despite endoscopic biliary stenting, some patients do not respond to treatment, and they experience recurrent cholangitis. We report two cases of CP with refractory BBS treated using endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) fistula creation. A 50-year-old woman and a 60-year-old man both presented with obstructive jaundice secondary to BBS due to alcoholic CP. They underwent repeated placement of a fully covered self-expandable metal stent for biliary strictures. However, the strictures persisted, causing repeated episodes of cholangitis. Therefore, an EUS-CDS was performed. The stents were eventually removed and the patients became stent-free. These fistulas have remained patent without cholangitis for more than 2.5 years. Fistula creation using EUS-CDS is an effective treatment option for BBS.

Backgrounds/Aims: Postoperative fluid collection is a common complication of pancreatic resection without clear management guidelines. This study aimed to compare outcomes of endoscopic ultrasound (EUS)-guided trans-gastric drainage and percutaneous catheter drainage (PCD) in patients who experienced this adverse event after pancreaticoduodenectomy (PD). Methods: Demographic and clinical data and intervention outcomes of 53 patients who underwent drainage procedure (EUS-guided, n = 32; PCD, n = 21) for fluid collection after PD between January 2015 and June 2019 in our tertiary referral center were retrospectively analyzed. Results: Prior to drainage, 83.0% had leukocytosis and 92.5% presented with one or more of the following signs or symptoms: fever (69.8%), abdominal pain (69.8%), and nausea/vomiting (17.0%). Within 8 weeks of drainage, 77.4% showed a diameter decrease of more than 50% (87.5% in EUS vs. 66.7% in PCD, p = 0.09). Post-procedural intravenous antibiotics were used for an average of 8.1 ± 4.3 days and 12.4 ± 7.4 days for EUS group and PCD group, respectively (p = 0.01). The EUS group had a shorter post-procedural hospital stay than the PCD group (9.8 ± 1.1 vs. 15.8 ± 2.2 days, p < 0.01). However, the two groups showed no statistically significant difference in technical or clinical success rate, reintervention rate, or adverse event rate. Conclusions: EUS-guided drainage and PCD are both safe and effective methods for managing fluid collection after PD. However, EUS-guided drainage can shorten hospital stay and duration of intravenous antibiotics use.
