Background/Aims: Endoscopic ultrasonography-guided gastrojejunostomy is a minimally invasive method for the management of gastric outlet obstruction. Conventionally, a lumen-apposing metal stent (LAMS) is used to create an anastomosis. However, LAMS is expensive and not widely available. In this report, we described a tubular fully covered self-expandable metallic stent (T-FCSEMS) for this purpose. Methods: Twenty-one patients (15 men [71.4%]; median age, 66 years; range, 40-87 years) were included in this study. A total of 19 malignant (12 pancreatic, 6 gastric, and 1 metastatic rectal cancer) and 2 benign cases were observed. The proximal jejunum was punctured with a 19 G needle. The stomach and jejunum walls were dilated with a 6 F cystotome, and a 20×80 mm polytetrafluoroethylene T-FCSEMS (Hilzo) was deployed. Oral feeding was initiated after 12 to 18 hours and solid foods after 48 hours. Results: The median procedure time was 33 minutes (range, 23-55 minutes). After two weeks, 19 patients tolerated oral feeding. In patients with malignancy, the median survival time was 118 days (range, 41-194 days). No serious complications or deaths occurred. All patients with malignancy tolerated oral food intake until they expired. Conclusions: T-FCSEMS is safe and effective. This stent should be considered as an alternative to LAMS for gastric outlet obstruction. [ABSTRACT FROM AUTHOR]

Objective The aim of this study was to optimize the currently used direct spectrophotometric serum prolidase enzyme activity (SPEA) assay method and compare its diagnostic accuracy with current precipitation and direct spectrophotometric assay methods, AST-to-ALT ratio, age platelet index, AST-to-platelet ratio index, cirrhosis discriminate score, Doha score, FIB-4, FibroQ, fibrosis index, Goteborg University Cirrhosis Index , King's score, and Pohl score for distinguishing Ishak F0 from F1–F3 in patients with chronic hepatitis B (CHB) infection. Methods Liver biopsy results from 112 patients were included in this study.  Results The SPEA values were 529 (292–794) U/L, 671 (486–927) U/L, and 1077 (867–1399) U/L with the precipitation, current, and optimized direct spectrophotometric assay methods, respectively. According to multivariate logistic regression analysis optimized direct spectrophotometric SPEA was the only statistically significant parameter to predict the early stages of liver fibrosis.  Conclusions Optimized direct spectrophotometric SPEA assay method could be used to distinguish early stages of liver fibrosis in patients with CHB infection instead of the currently used spectrophotometric SPEA assay methods and other evaluated liver fibrosis indexes.

Objective: Mechanical dilatation and adjuvant injection of triamcinolone acetate (TA) effectively preserve the opening provided and reduce the number of bougie dilation (BD) in benign esophageal strictures. In this study, we aimed to evaluate the role of Methylprednisolone (MP) injection after BD in providing permanent/long-term lumen opening. Materials and Methods: Among 22 patients diagnosed with benign esophageal strictures (BES) between January 2017 and October 2020, we evaluated the results of 8 patients who continued the endoscopic follow-up program and underwent BD and MP injection, then compared with the literature. Results: We treated 8 patients [6 (75%) women, mean age 61±16.9 years (range 22-77)] with strictures of different etiologies (3 anastomotic, 2 iatrogenic esophageal rupture repairs, 2 recurrent webs, and 1 scleroderma) with BD followed by intralesional MP injection. We performed median BD sessions 3.5 times (range 1-8). We gave a median 3 intralesional MP injection (range 1-7). The median time to resolve stricture was 2.5 months (range 1-4). The median endoscopic follow-up time was 4.5 months (range 1-17). Conclusions: Adjuvant MP injection is successful in preserving the lumen patency provided after mechanical dilatation. Randomized controlled studies are needed to determine the steroid type and dose to provide the most optimal permanent lumen opening with lesser dilatation sessions in BES. [ABSTRACT FROM AUTHOR]

Background/Aims: The role of cyst fluid carcinoembryonic antigen (CEA) level in differentiating mucinous pancreatic cystic lesions (PCLs) is controversial. We investigated the role of cyst fluid CEA in differentiating low-risk (LR)-intraductal papillary mucinous neoplasms (IPMNs) from high-risk (HR)-IPMNs and LR-mucinous cystic neoplasms (MCNs). Methods: This was a retrospective study of 466 patients with PCLs who underwent endoscopic ultrasound-guided fine-needleaspiration over a 7-year period. On histology, low-grade dysplasia and intermediate-grade dysplasia were considered LR, whereas high-grade dysplasia and invasive carcinoma were considered HR. Results: Data on cyst fluid CEA levels were available for 50/102 mucinous PCLs with definitive diagnoses. The median CEA (range) levels were significantly higher in HR cysts than in LR cysts (2,624 [0.5–266,510] ng/mL vs. 100 [16.8–53,445] ng/mL, p=0.0012). The area under the receiver operating characteristic curve (AUROC) was 0.930 (95% confidence interval [CI], 0.5–0.8; p<0.001) for differentiating LR-IPMNs from LR-MCNs. The AUROC was 0.921 (95% CI, 0.823–1.000; p<0.001) for differentiating LR-IPMNs from HR-IPMNs. Both had a CEA cutoff level of >100 ng/mL, with a negative predictive value (NPV) of 100%. Conclusions: Cyst fluid CEA levels significantly vary between LR-IPMNs, LR-MCNs, and HR-IPMNs. A CEA cutoff level of >100 ng/mL had a 100% NPV in differentiating LR-IPMNs from LR-MCNs and HR-IPMNs.

Introduction:Endosonography guided celiac plexus neurolysis is efficacious in the management of severe pain due to advanced pancreatic cancer. Although endoscopic ultrasound (EUS) guided celiac neurolysis (CN) is mostly a safer procedure than the percutaneous posterior approach, severe complications such as paraplegia have been reported. Case report:We describe a patient with advanced adenocarcinoma of the pancreas and severe pain who developed irreversible paraplegia after EUS guided CN. Conclusions:Endosonography guided celiac plexus neurolysis also might be complicated with paraplegia as already observed with percutaneous approach. The underlying mechanism could not be explained clearly until now. We detected concomitant embolic occlusion of Adamkiewicz and anterior radicularis magna arteries in magnetic resonance angiography. So, this procedure must be considered only for malignancy patients. [ABSTRACT FROM AUTHOR]
