European' health care indicators and pancreatic cancer incidence and mortality: A mediation analysis of Eurostat data and Global Burden of Disease Study 2019.

AIM: To highlight correlations existing between incidence and mortality of pancreatic cancer, and health care indicators in 36 European countries. METHODS: The Global Burden of Disease (GBD) and Eurostat databases were queried between 2004 and 2019. Incidence and mortality were age-standardized. From Eurostat, indicators regarding expenditure, hospital beds, medical technology, health personnel, physicians by medical specialty and unmet needs for medical examination were extracted. Correlations between GBD and Eurostat data were analysed through mediation analysis applying clustering for countries. RESULTS: Incidence increased by +0.6% per year (p = 0.001) and mortality by +0.3% (p = 0.001), being increasing for most of the European countries considered. Incidence and mortality were strongly positively correlated (p = 0.001). Higher current health expenditure, expenditure in inpatient curative care, the number of available beds, the number of computed tomography scan, magnetic resonance units, practising medical doctors were all related to higher incidence (p < 0.05), whereas the unmet need for medical examinations was related to lower incidence. When the mediator' effect of incidence was handled, these indicators, together with expenditure on outpatient curative cares, the number of pet scanners and of radiation therapy equipment, were related to lower mortality (p < 0.05). CONCLUSIONS: Health care environment correlates with reported incidence and mortality of pancreatic cancer. This highlights both that ameliorated socio-economic societies suffer from higher incidence but lower mortality, as well as the epidemiological bias originating from countries' diagnostic ability.

Micro-Biopsy Forceps in the Assessment of Peritoneal Carcinomatosis: A Possible New Indication?

Peritoneal carcinomatosis (PC) is defined as a metastatic involvement of the peritoneum by several other primary sites and it is characterized by a marked worsening of prognosis, with limited treatment opportunities. Subsequently, PC should be ruled out before any invasive treatment is administered. A new through-the-needle micro-biopsy forceps (MF) was recently introduced that permits micro-histology cores. In this case series, we evaluated the feasibility of MF in the assessment of PC to complete patient diagnostic work-ups. Five consecutive patients referred for endoscopic ultrasound staging were sampled using MF. Sampling was feasible in all patients with a technical success of 100%. No adverse events were reported in any cases. This technique was feasible and safe with a technical success rate of 100%. It permitted sampling of peritoneal irregularity, obtained high-quality tissue fragments in all cases, and enabled an additional assessment, i.e., immunohistochemical staining.

Single session versus separate session endoscopic ultrasonography plus endoscopic retrograde cholangiography in patients with low to moderate risk for choledocholithiasis.

BACKGROUND AND AIM: Endoscopic ultrasonography (EUS) is a minimally invasive diagnostic tool for common bile duct stones (CBDS) and may be used to select patients for therapeutic endoscopic retrograde cholangiography (ERC). The aim of this trial is to compare, in patients with non-high-risk for CDBS, the clinical and economic impact of EUS plus ERC performed in a single endoscopic session versus EUS plus ERC in two separate sessions. METHODS: During an 11-month period, all adult patients admitted to the emergency department with suspicion of CBDS were categorized into either high-risk or non-high-risk groups, on the basis of clinical, biochemical, or transabdominal ultrasound findings. Patients in the non-high-risk group were randomized to receive EUS plus ERC in one single or in two separate sessions. RESULTS: Eighty patients were recruited and randomized. Forty patients underwent EUS plus ERC in a single session and 40 patients underwent EUS plus ERC in two separate sessions. Negative EUS examination for CBDS avoided unnecessary ERC to 33 patients. Out of 47 patients with positive EUS (25 from the single session group and 22 from the double session), ERC confirmed the presence of CBDS in 46 cases (EUS sensitivity 100% and specificity 98%). Average time of procedure and hospitalization were significantly shorter in the single session group compared to the two session group. The single session strategy was also less expensive. CONCLUSION: Endoscopic ultrasonography plus ERC with sphincterotomy and stone extraction performed during the same endoscopic session was safe and efficacious with a reduction of procedure time, hospitalization and costs.

Clinical usefulness of gastric-juice analysis in 2007: the stone that the builders rejected has become the cornerstone.

BACKGROUND: Gastric juice is usually discarded during upper-GI endoscopy. OBJECTIVE: By using a novel device, the Mt 21-42, we evaluated the potential of this important organic fluid in clinical practice, exploring its contribution to the diagnosis of Helicobacter pylori infection and atrophic gastritis of the oxyntic mucosa (AGOM). DESIGN AND PATIENTS: A multicenter study (17,907 patients; 10 endoscopy units) estimated the frequency of diagnosis of AGOM and H pylori infection in routine endoscopic practice. A prospective study (216 patients) at 1 of these units aimed to determine the real prevalence of these conditions and the possible benefits of gastric juice analysis. We considered gastric juice pH and ammonium concentration, endoscopic and histologic features, serologic parameters for atrophy and H pylori, gastric acid secretion, and costs. RESULTS: We found that H pylori infection and, even more markedly, AGOM were greatly underdiagnosed in routine endoscopic practice (20.1% and 0.8% vs 49.1% and 12.5% in the prospective study, respectively), because of the intrinsic limitations of the conventional tests and lack/inappropriateness of biopsy planning. Gastric-juice analysis proved to be a cheap, simple, and effective way to prevent such underdiagnosis and allowed detection of atrophic gastritis and H pylori in 96% and 98% of cases, and saved costs (cost-effectiveness ratio 209 vs 274-5047). CONCLUSIONS: Gastric juice provided a valuable source of clinicopathologic information that, properly analyzed, allowed detection of the main risk factors for gastric cancer (H pylori and atrophic gastritis), overcoming the diagnostic limitations associated with these conditions and also producing time and cost savings.
