This study explored factors that can predict effectiveness outcomes after transarterial radioembolization in colorectal liver metastases in the liver. In a cohort of 237 patients, among other factors, we found that an Aspartate transaminase to Platelet Ratio Index (APRI) value of > 0.40 was a particularly strong independent predictor of worse overall survival, progression-free survival and hepatic progression-free survival outcomes. Background: Transarterial radioembolisation (TARE) with Yttrium-90 resin microspheres is a treatment option for patients with metastatic colorectal cancer in the liver (mCRC). A better understanding of the prognostic factors and treat-ment application can improve survival outcomes. Methods: We analysed the safety and effectiveness of 237 mCRC patients included in the prospective observational study CIRSE Registry for SIR-Spheres Therapy (CIRT) for indepen-dent prognostic factors for overall survival (OS), progression-free survival (PFS) and hepatic progression-free survival (hPFS) using the Cox proportional-hazard model. Results: The median OS was 9.8 months, median PFS was 3.4 months and median hPFS was 4.2 months. Independent prognostic factors for an improved overall survival were the absence of extra-hepatic disease ( P = .0391), prior locoregional procedures ( P = .0037), an Aspartate transaminase to Platelet Ratio Index (APRI) value of 0.40 ( P = .0416) and prior ablation ( P = .0323), and for hPFS these were 2 to 5 tumor nodules ( P = .0148), Albumin-bilirubin (ALBI) grade 3 ( P = .0075) and APRI > 0.40 ( P = .0207). During the study, 95 of 237 (40.1%) patients experienced 197 adverse events, with 28 of 237 (11.8%) patients having a grade 3 or higher adverse events. Conclusion: Including easy-to-acquire laboratory markers INR, APRI, ALBI and using partition model dosimetry can identify mCRC patients that may benefit from TARE.

Background. The clinical features of a presumed capsaicin intoxication have not been reported so far. Case Presentation. A 27-year-old man took part in a qualifying for a competition in spicy food tolerance. During this qualifying, he swallowed 4 chili peppers type Bhut jolokia (about 1 million Scoville units) and other extremely spicy foods; the total amount of capsaicin ingested (roughly calculated retrospectively) accounted for at least 600 mg. After 2½ hours, the patient developed severe abdominal pain, which led to hospital admission. In contrast to the severe symptoms, clinical, laboratory, and imaging examinations (ultrasound and plain X-ray of the abdomen) did not reveal any significant abnormalities. Treatment with analgesics resulted in complete regression of the abdominal pain within 30 hours. Conclusions. The clinical picture in the view of pharmacological investigations on intestinal capsaicin infusions suggests that excessive doses of capsaicin can induce severe abdominal pain; the prolonged symptoms were probably due to the failure to vomit. Thus, a capsaicin intoxication must be considered in the differential diagnosis of an acute abdomen.

ZusammenfassungNeben ihrem diagnostischen Potenzial erlaubt die Koloskopie auch die endoskopische Resektion von Polypen und Frühkarzinomen. Mit der konventionellen Schlingenresektion, der endoskopischen Mukosaresektion (EMR), der endoskopische Submukosadissektion (ESD) und neuerdings der endoskopischen Vollwandresektion (eFTR) stehen verschiedenene intraluminale Resektionsverfahren zur Verfügung, die in diesem Artikel vorgestellt werden.

The aim of the study was to evaluate the usefulness and diagnostic and therapeutic outcome of the single-operator cholangiopancreatoscopy (SOC) with SpyGlassDS™. In a retrospective multicenter study between November 2015 and January 2017, SpyGlassDS™ procedures were analyzed in participating centers. Indications, accuracy of SOC-guided biopsies, management of large bile duct stones, and complications were analyzed. Follow-up was 4 months. Two hundred and six patients out of 250 examinations were evaluated. Indications were biliary stones (n = 132), bile duct stenosis (n = 93), stones and stenosis combined (n = 24), and bile duct leakage (n = 1). Of the 117 cases which were suspicious of malignancy, in 99 cases the lesion could be stratified into benign (n = 55) or malignant (n = 44) indicating a sensitivity of 95.5% and a specificity of 94.5% for the indication tumor. SOC-guided biopsies revealed a sensitivity of 57.7% with a specificity of 100%. In 107 examinations, biliary stones were visualized and could be completely removed in 91.1% with a need of three procedures (range 1–6) to achieve final stone clearance. In 75 cases, lithotripsy was performed and was successful in 71 cases (95%). Four out of 45 patients (8.9%) underwent cholecystectomy with surgical bile duct revision as a final therapy. Adverse Event (AE) occurred in 33/250 patients (13.2%) and Serious Adverse Event (SAE) occurred in 1/250 patients (0.4%). Cholangitis was 1% (n = 102) after peri-interventional administration of antibiotics and 12.8% (n = 148) without antibiotic prophylaxis (p

Glucagon-like peptide 1 (7–37)/(7–36) amide (GLP-1) is derived from the intestinal proglucagon processing. It is considered an important insulin-releasing gut hormone. This study uses exendin (9–39) amide as a GLP-1 receptor antagonist to evaluate the contribution of GLP-1 to the incretin effect. Anesthetized rats were challenged by an intraduodenal glucose infusion to evaluate maximally occurring GLP-1 and gastric inhibitory polypeptide (GIP) plasma levels. Maximal immunoreactive (IR) GLP-1 plasma levels amounted to 10 pmol/l (IR-GIP 11 pmol/l). Exendin (9–39) amide abolished the insulin-stimulatory effect of 60 pmol of GLP-1 or of the GLP-1 agonist exendin-4 (0.5 nmol) injected as bolus, respectively. An intravenous bolus injection of 5.94 nmol of exendin (9–39) amide 3 min before enteral glucose infusion grossly reduced the total insulin secretory response (by 60%) and significantly increased circulating blood glucose levels (P < 0.05). In contrast, the GLP-1 antagonist left the insulin response after an intravenous glucose or glucose plus GIP (60 pmol) load unaltered. Our data support the concept that GLP-1 is an important incretin factor. Exendin (9–39) amide is a useful GLP-1 antagonist for in vivo studies.
