Introduction: Transabdominal ultrasound (TU) pancreatic 2D-SWE elastography is a developing technique that needs to be protocolized., Objectives: Establish a protocol for image acquisition and measurement of TU pancreatic - 2D-SWE elastography and estimate the minimum number of measurements to be performed., Materials and Methods: Ten measurements of pancreatic elasticity were taken in healthy volunteers using TU-2D-SWE, following a strict protocol for image acquisition and measurement., Results: The 70% of the participants were women, with an average age, weight, and BMI of 49.5±15.7 years, 65.9±11.9kg, and 24.5±4.2kg/m 2 , respectively. Measurements were taken from the body (70%), tail (16.7%), and pancreatic head (13.3%). The median mean velocity and elasticity were 1.46±0.25cm/sec and 6.46±2.87KPa, respectively. The ROI depth was 4.12±1cm and the SP-ROI distance was 5.2mm on average. There were no statistically significant differences between the 10 measurements. The reliability analysis of the measurements showed high internal consistency and repeatability. Taking 5-6 measurements ensured high concordance with the ten reference measurements. The measurements were significantly lower when the SP-ROI values were intermediate (0.3-0.6cm). The measurement accuracy was higher when performed at a depth less than 4.8cm., Conclusion: To measure pancreatic elasticity using TU-2D-SWE, we propose a strict protocol for image acquisition and measurement, taking a minimum of 5 measurements in the best visualized and accessible pancreatic portion, and preferably at a depth of less than 4.8cm., (Copyright © 2024 Elsevier España, S.L.U.

Introduction and Objectives: TPE drastically reduces serum triglyceride (sTG), but its role in the treatment of hypertriglyceridemia-induced acute pancreatitis (HTG-AP) or at risk of developing it, is not well established. The objectives were to assess the effectiveness and safety of TPE in the treatment of severe HTG (sHTG), as well as to evaluate the severity of HTG-AP treated with TPE., Materials and Methods: Observational-retrospective-single-center study, in which a descriptive analysis of sHTG treated with TPE was conducted, with the aim of treating HTG-AP or preventing its recurrence. TPE was performed if sTG≥ 1000 mg/dL after 24 hours of admission., Results: 42 TPE were performed to treat 35 sHTG in 23 patients: 29 HTG-AP, and 6 sHTG with previous HTG-AP. Among the patients, 37% (13/55) were women, with 37 ± 14 years-old, 74.3% had normal BMI (25/35), 34% (12/35) were drinking > 40 g/alcohol/day and 54% (19/35) were diabetics. TPE significantly reduced the baseline sTG (4425 ± 2782 mg/dL vs. 709 ± 353 mg/dL, p < 0.001) in a single session, achieving a mean percentage reduction of 79 ± 13%; 20% (7/35) of sHTG cases required two TPE sessions to reduce sTG to < 1000 mg/dL. Adverse effects were reported in 4/42 TPE sessions (9,5%). sHTG-AP was observed in 3% of cases (1/29), and there were no deaths. sTG at 24 hours of admission showed no relation with the severity of APs., Conclusion: The treatment of sHTG with TPE, with the aim of treating HTG-AP or preventing its recurrence, reduces sTG quickly and safety., (Copyright © 2024 Elsevier España, S.L.U.

Background/objectives: Exocrine pancreatic insufficiency (EPI) is an important complication of chronic pancreatitis (CP). Guidelines recommend to rule out EPI in CP, to detect those patients who would benefit from pancreatic enzyme replacement therapy. The aim of this study was to evaluate the prevalence of EPI in patients with CP without follow-up in the last 2 years and to describe their nutritional status and quality of life (QoL)., Methods: This was a cross-sectional, multicenter Spanish study. CP patients without follow-up by a gastroenterologist or surgeon in at least 2 years were included. EPI was defined as fecal elastase test <200mcg/g. For nutritional assessment, laboratory and anthropometric data were obtained. QoL was investigated using the EORTC QLQ-C30 questionnaire., Results: 64 patients (mean age 58.8±10.3 years, 85.9% men) from 10 centers were included. Median time since diagnosis of CP was 58.7 months [37.7-95.4]. Forty-one patients (64.1%) had EPI. Regarding nutritional status, the following differences were observed (EPI vs. Non-EPI): BMI (23.9±3.5kg/m 2 vs. 25.7±2.5, p=0.03); glucose (121 [96-189] mg/dL vs. 98 [90-116], p=0.006); HbA1c 6.6% [6.0-8.4] vs. 5.5 [5.3-6.0], p=0.0005); Vitamin A (0.44mg/L [0.35-0.57] vs. 0.53 [0.47-0.63], p=0.048) and Vitamin E (11.2±5.0μg/ml vs. 14.4±4.3, p=0.03). EPI group showed a worse EORTC QLQ-C30 score on physical (93.3 [66.7-100] vs. 100 [93.3-100], p=0.048) and cognitive function (100 [83.3-100] vs. 100 [100-100], p=0.04)., Conclusions: Prevalence of EPI is high in patients with CP without follow-up. EPI group had higher levels of glucose, lower levels of vitamins A and E and worse QoL., (Copyright © 2017 Elsevier España, S.L.U. All rights reserved.)

Cronkhite-Canada syndrome is an infrequent, nonadenomatous, acquired polyposis that is associated with ectodermic alterations. The etiopathogenesis and optimal therapeutic management are unknown. We present a case of Cronkhite-Canada syndrome in a 58-year-old man who, after combined treatment with corticosteroids, disodium cromoglycate, loratadine, ciprofloxacin, and zinc, showed complete clinical and partial endoscopic remission. The polypoid lesions of Cronkhite-Canada syndrome can be reversed with medical treatment. Consequently, the natural history of the disease can be modified and its prognosis improved.
