RESUMEN
BACKGROUND AND AIMS: Pancreas divisum (PD) is a congenital variant of the pancreatic ductal system and a potential cause of acute recurrent pancreatitis (ARP). Endoscopic minor papilla sphincterotomy (MiES) is the most common procedure performed in the management of PD-related ARP. The aim of this study is to perform a meta-analysis estimating the efficacy and the safety of MiES in the management of patients with PD-related ARP. METHODS: A research was performed in Pubmed, EMBASE and Web of science, the studies were reviewed and selected according to inclusion and exclusion criteria. Evaluation of Heterogeneity and publication bias was performed, and a random effect model was used to estimate the effect size of each study. RESULTS: One hundred and thirteen articles were selected and reviewed, 13 met the inclusion criteria. All the studies were retrospective with a mean follow-up duration of 45.9 months. A total of 323 patients with PD-related ARP treated with MiES were included in the meta-analysis. The overall clinical success rate of MiES (defined as no further episodes of ARP, reduction of episodes of ARP, or improvement in quality of life) was of 77% (95%CI: 72%-81%; p = 0.30). Evaluating only the studies with clinical success rate defined as "no further AP in the follow-up" the clinical success rate was of 69.8% (95%CI: 61.3%-77.2%; p = 0.57), while evaluating the studies with other definitions (reduction of episodes of ARP or improvement in quality of life) the clinical success rate was of 81.2% (95%CI: 75.2%-86.1%; p = 0.45). The common fixed effects model disclosed a 25.5% overall adverse events rate (95%CI: 19.3%-32.8%; p = 0.42): acute pancreatitis in 14.3% (95%CI: 9.7%-20.6%; p = 0.36), bleeding in 5.6% (95%CI: 2.9%-10.4%; p = 0.98), and other adverse events in 5.6% (95%CI: 2.9%-10.4%; p = 0.67). CONCLUSION: MiES is an effective and relatively safe treatment in the management of PD-related ARP. The retrospective nature of the studies selected is the main limitations of this metanalysis. Prospective trials are needed to confirm these data.

BACKGROUND: Acute recurrent pancreatitis (ARP) is a rare manifestation of Intraductal Papillary Mucinous Neoplasms (IPMN) of the pancreas; ARP is a relative indication for pancreatic surgery in the setting of IPMN. Endoscopic pancreatic sphincterotomy (EPS) has been described as a minimal invasive treatment to reduce the episodes of ARP secondary to mucus migration in IPMN. METHODS: patients with IPMN-related ARP treated with ESP from January 2004 to December 2020 were retrospectively selected. Clinical and technical data were recorded. A clinical follow-up (minimum 12 months) was performed to assess the number of episodes of AP occurring after EPS. RESULTS: 25 patients were included. The mean follow-up after ESP was 93.4 months (SD± 56.6). The mean number of AP before and after EPS were respectively 3.29 (SD ± 1.04) and 0.51 (SD ± 0.71). A complete response (no further episodes of AP) and a partial response (>50% reduction of AP episodes) were obtained in 64% and 24% of the cases, respectively, with an overall response rate of 88%. One post-EPS bleeding and one minor-papilla stenosis were reported and were endoscopically managed. Two patients underwent pancreatic resection for the occurrence of high-risk stigmata for cancer progression. CONCLUSIONS: EPS is a safe and effective treatment to reduce the number of episodes of AP in selected patients with IPMNs-related ARP. Prospective trials are needed to confirm these data.

OBJECTIVE: The Coronavirus Disease 2019 (COVID-19) pandemic mainly involves respiratory symptoms, though gastrointestinal (GI) symptoms are increasingly being recognized. In this context, the presence of comorbidities appears to be associated with adverse outcomes. However, the role of digestive manifestations is not yet well defined. The primary aim of this study was to assess the prevalence of GI symptoms and digestive comorbidities in a cohort of patients with COVID-19 compared to controls. The secondary aim was to determine the association of GI-symptoms and digestive comorbidities with clinical outcomes. PATIENTS AND METHODS: Inpatients with COVID-19 and controls with similar symptoms and/or radiological findings were enrolled. Symptoms at admission and throughout hospitalization were collected as they were comorbidities. The measured clinical outcomes were mortality, intensive care unit admission and cumulative endpoint. RESULTS: A total of 105 patients were included: 34 with COVID-19 and 71 controls. At admission, the prevalence of GI symptoms among COVID-19 patients was 8.8%. During hospitalization, the frequency of GI symptoms was higher in patients with COVID-19 than in controls (p=0.004). Among patients with COVID-19, the mortality and a cumulative endpoint rates of those with GI symptoms were both lower than for those without GI symptoms (p=0.016 and p=0.000, respectively). Finally, we found digestive comorbidities to be associated with a milder course of COVID-19 (p=0.039 for cumulative endpoint). CONCLUSIONS: Our results highlighted the non-negligible frequency of GI symptoms in patients with COVID-19, partly attributable to the therapies implemented. In addition, the presence of GI symptoms and digestive comorbidities is associated with better outcomes. Most likely, digestive comorbidities do not hinder the host's immune response against SARS-COV-2, and the occurrence of GI symptoms might be linked to a faster reduction of the viral load via the faecal route.

The involvement of gastrointestinal system in SARS-CoV2 related disease, COVID-19, is increasingly recognized. COVID-19 associated pancreatic injury has been suggested, but its correlation with pancreatic disease is still unclear. In this case report, we describe the detection of SARS-CoV2 RNA in a pancreatic pseudocyst fluid sample collected from a patient with SARS-CoV2 associated pneumonia and a pancreatic pseudocyst developed as a complication of an acute edematous pancreatitis. The detection of SARS-CoV2 within the pancreatic collection arise the question of whether this virus has a tropism for pancreatic tissue and whether it plays a role in pancreatic diseases occurrence.

The aim of the study was to determine the impact of vessel attenuation on quantitative 64-slice computed tomography coronary angiography (CTCA). CTCA and invasive quantitative coronary angiography (QCA) were performed in 100 consecutive patients (42 women, 58 men; mean age 64.4+/-9.4 years; age range 39-87 years). In QCA, stenoses were quantified with dedicated software, whereas in CTCA, stenosis severity was assessed with an electronic caliper tool: stenoses were graded in 10% steps and assigned as either a calcified or non-calcified lesion. Vessel attenuation in the left main (LMA) and the proximal right coronary artery (RCA) were measured and correlated with differences in quantifications of stenosis grade between QCA and CTCA. A total of 113 coronary stenoses were detected by both methods (94 significant and 19 non-significant); 52 stenoses were rated as non-calcified and 61 as calcified lesions. The mean difference between QCA and quantitative CTCA grading was 5.1+/-16.9% (range -27 to 46%) overall; 1.9+/-14.2% (range -27 to 38%) for non-calcified lesions and 7.8+/-18.6% (range -23 to 46%) for calcified lesions. Mean vessel attenuation was 362+/-76 HU (range 191-584 HU) in the LMA and 333+/-81 HU (range 162-564 HU) in the RCA. Attenuation did not significantly correlate with differences in QCA and CTCA gradings, neither overall nor for calcified or non-calcified lesions. When 64-slice CTCA is used, coronary vessel attenuation had no impact on the quantitative grading of stenoses.

PURPOSE: To evaluate the influence of the body mass index (BMI) on coronary artery opacification in 64-slice CT. MATERIAL AND METHODS: Sixty-two patients retrospectively underwent ECG-gated 64-slice CT coronary angiography (tube potential 120 kV, tube current time product 650 mAs) after intravenous injection of 80 ml of iodinated contrast agent (320 mg/ml, 5 ml/s). Attenuation values (HU) were measured and contrast-to-noise ratios (CNR) were calculated in the right coronary artery (RCA) and left main artery (LMA). The CNR was defined as the difference between the mean attenuation in the vessel and the mean attenuation in the perivascular fat tissue divided by the image noise in the ascending aorta. The height and weight of the patients at the time of the CT scan were recorded and the BMI was calculated. RESULTS: The mean BMI was 26.2 +/- 3.2 kg/m (2) (range 19.7 - 32.2 kg/m (2)), the mean attenuation in the LMA was 330 +/- 64 HU, and the mean attenuation in the RCA was 309 +/- 68 HU. The CNR in the LMA was 16.7 +/- 3.8, and the CNR in the RCA was 15.9 +/- 3.6. The image noise in the ascending aorta significantly correlated with the BMI (r = 0.36, p < 0.01). A weak negative correlation was found between the BMI and LMA attenuation (r = - 0.28, p < 0.05), whereas no significant correlation was found for the RCA (r = - 0.21, p = 0.12). A significant negative correlation was found between the BMI and the CNR in the RCA (r = - 0.41, p < 0.05) and the LMA (r = - 0.47, p < 0.001). CONCLUSION: With constant scan parameters and a constant contrast medium amount, the CNR in both coronary arteries decreases while the BMI increases. This implies a modification of previously standardized and fixed examinations with respect to individually adapted protocols with variable parameters for CT coronary angiography.
