Peroral cholangioscopy (POCS)-guided forceps biopsy is a method for diagnosing indeterminate biliary strictures and the preoperative identification of exact perihilar distal margins tract cancer (BTC). However, POCS-guided may result in an insufficient amount specimen at times. Therefore, we evaluated adequate tissue acquisition rate factors affecting tract.Patients who underwent disease between September 2016 October 2018 our hospital were enrolled retrospectively. We lesion that...
Background: Peroral cholangioscopy (POCS) has become a widely-used technique in diagnosing indeterminate biliary strictures, enabling optical viewing of the system and targeted biopsies under direct vision. The diagnostic utility new endoscopic scraper, Trefle®, for extrahepatic cholangiocarcinoma (ECC) also been reported. However, POCS-guided Trefle®-assisted tissue acquisition ECC never compared empirically. We evaluated efficacy safety with sampling. Methods: Patients who underwent or...
Peroral cholangioscopy (POCS) is believed to be effective in treating intrahepatic stones; however, reports on its efficacy are few. We reviewed the results of stones treated with fluoroscopic guidance or POCS. This study included 26 patients who underwent endoscopic treatment for at our institution between January 2017 and December 2021. retrospectively evaluated procedure time adverse events first session rate complete stone removal. Complete removal was achieved 92% (24/26); POCS required...
Endoscopic retrograde cholangiopancreatography (ERCP)-related tissue acquisition, including fluoroscopy-guided forceps biopsy (F-FB), is a common technique in diagnosing indeterminate biliary lesions. Recently, peroral cholangioscopy (POCS) and POCS-guided (POCS-FB) has also been used for the diagnosis of However, it uncertain which those techniques were superior extrahepatic cholangiocarcinoma (ECC). We aimed to evaluate diagnostic yield safety F-FB lesions compared with POCS-FB.Patients...
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is an essential endoscopic tissue sampling method for diagnosing pancreatobiliary diseases; however, determining the presence of target specimens mixed in blood by conventional observation challenging due to small size obtained sample. This study investigated usefulness a sample check illuminator (TSCI) that emits specific wavelength light determine specimens. Twenty-seven patients who underwent EUS-FNA at our hospital were...
Pathological examination by endoscopic ultrasound-fine needle aspiration is not possible in approximately 10% of pancreatic tumor cases. Pancreatic juice cytology (PJC) considered an alternative diagnostic method. However, its capability insufficient, and PJC has been repeatedly redevised. Serial cytological (SPACE) secretin-loaded (S-PJC) have recently introduced as methods. This study aimed to determine the capacity safety SPACE S-PJC using a propensity score-matched analysis. The...
We report the case of a 68-year-old woman who had abdominal pain and slightly elevated biliary enzymes. Magnetic resonance cholangiopancreatography detected duct stenosis, while contrast-enhanced magnetic imaging showed that right hepatic artery transversed extrahepatic bile at level bifurcation duct. performed endoscopic retrograde peroral cholangioscopy with SpyGlass DS™ system. Then, mild extrinsic pulsatile compression was observed stricture an intact epithelium. Therefore, she diagnosed...
Background: Peroral cholangioscopy (POCS)-guided forceps mapping biopsy (FMB) is a method for the accurate preoperative identification of extent disease biliary tract cancer (BTC). However, diagnostic value POCS-FMB still uncertain. Objectives: We evaluated utility lateral extension—superficial intraductal spread longitudinally and continuously from main lesion—of BTC. Methods: In retrospective study, patients who received surgery curative resection BTC between September 2016 August 2019 at...
The risk of malignant transformation intraductal papillary mucinous neoplasm (IPMN) is presently assessed using imaging, which remains unsatisfactory. Given the high viscosity pancreatic juice, juice cytology (PJC) considered an investigational procedure. We previously demonstrated that diagnostic performance PJC was improved via synthetic secretin loading in ductal carcinoma. This study aimed to evaluate efficacy secretin-loaded (S-PJC) for IPMN. usefulness and safety S-PJC were...
(1) Background: There is controversy regarding stent placement for unresectable malignant hilar biliary obstruction (UMHBO). We mainly use the partial stent-in-stent (PSIS) method with an uncovered self-expandable metallic (UCSEMS) based on drainage area and patency period. In this study, we investigated usefulness safety of PSIS method. (2) Methods: total, 59 patients who underwent UMHBO at our hospital were included in study. The technical success rate, clinical time to recurrent (TRBO)...
Photodynamic therapy (PDT) has advanced through the utilization of photosensitizers and specific-wavelength light (≥ 600 nm). However, widespread adoption PDT is still impeded by high equipment costs stringent laser safety requirements. Porphyrins, crucial in PDT, have another absorbance peak blue (λ = 380 - 500 This corresponds to wavelength narrow-band imaging (NBI) 390 445 nm), an image-enhancement technology integrated into endoscopes Olympus Medical Systems. The study aimed investigate...
: Although peroral cholangioscopy has improved the endoscopic treatment of difficult stones, intrahepatic stones remains challenging. The incidence cholangitis is high when used to treat stones. This study aimed investigate efficacy and safety with for common bile duct
Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) is a common technique for diagnosing pancreatic lesions with high accuracy and low incidence of procedural adverse events. However, occasional events, particularly bleeding, may occur. Procedures hypervascular are considered important, but their risks unknown. We aimed to evaluate the safety diagnostic yield EUS-FNB solid lesions. This study included 301 patients 308 who underwent between May 2011 December 2018. performed...
A diagnosis of tuberculous peritonitis (TBP) is difficult because nonspecific manifestation and limited effectiveness conventional diagnostic tools. Recently, the usability measurement ascitic adenosine deaminase (ADA) was shown. We report here a case TBP in which ADA contributed to diagnosis. 93-year-old male developed large amount ascites. Analyses fluid revealed exudation, though antibiotics treatment ineffective. Using paracentesis, level ascites measured shown be high. Under suspicion...
A 65-year-old man had a history of cholecystectomy and treatment for cholelithiasis with common bile duct incision. Owing to frequent cholangitis, he underwent choledochojejunostomy. Twenty years after the surgery, was hospitalized cholangitis suspected having hilar cholangiocarcinoma based on imaging findings. Percutaneous transhepatic cholangioscopy using SpyGlass™ DS (Boston Scientific, Marlborough, USA) showed gallstones sludge in ducts, but no tumors were noted. Electrohydraulic...
Abstract Background: Peroral cholangioscopy (POCS)-guided forceps biopsy is a method for diagnosing indeterminate biliary strictures and the preoperative identification of exact perihilar distal margins tract cancer (BTC). However, POCS-guided may result in an insufficient amount specimen at times. Aims: We evaluated sufficient tissue acquisition rate factors affecting tract. Methods: Patients who underwent disease between September 2016 October 2018 our hospital were enrolled...
This study constructed a simplified post-endoscopic submucosal dissection (ESD) prediction model with prognostic nutritional index (PNI). A total of 449 patients who underwent gastric ESD was included, divided ratio 2:1, and assigned to the or validation cohort. post-ESD (modified BEST-J score) using The modified score evaluated by comparing its accuracy in Within 4 weeks ESD, melena, hematemesis, 2 g/dL greater decrease hemoglobin level that required esophagogastroduodenoscopy defined as...
Objective Acute cholangitis is occasionally life-threatening and requires immediate treatment. For the management of acute cases, globally accepted diagnostic criteria use severity grading, as defined in Tokyo Guidelines 2018 (TG18), are recommended. This study was performed to explore association between level adenosine 5'-triphosphate (ATP) blood determined with a simple measurement method.
