The most frequent pancreatic cancer is pancreatic adenocarcinoma. It has high and early locally and distant invasiveness; this is the reason why it often shows little sign or symptoms in early stage and poor prognosis after the diagnosis, frequently in advanced stage. Although it is possible to detect this tumor in early stage because of its neoplastic precursor (PanINs). Epidemiological data shows that pancreatic cancer is not very common but obvious it is one of the most neoplastic death-cause in the world. The trend of incidence is quite increasing through years, proportionally to the increase of risk factors. About risk factors, it is not easy to detect in all the cases but it is known the role of some of that: there are hereditary risk factors, such as genetic pattern like HBOC, HNPCC, FAP, PJS, FAMMM, HP and CF and environmental ones (modifiable) such as smoke, alcohol consumption, chronic pancreatitis, obesity and diabetes mellitus. This narrative review aims to analyze the epidemiological data of pancreatic cancer and associated risk factors.

The inflammatory bowel diseases (IBDs) are systemic conditions that affect not only the gastrointestinal tract but also other parts of the body. The presence of extraintestinal manifestations can significantly impact the quality of life in IBD patients. Peripheral arthritis, episcleritis, and erythema nodosum are frequently associated with active intestinal inflammation and often improve with standard treatment targeting intestinal inflammation. In contrast, anterior uveitis, ankylosing spondylitis, and primary sclerosing cholangitis typically occur independently of disease flares. The incidence of these conditions in individuals with IBD can reach up to 50% of patients over the course of their lifetime. In addition, some advanced therapies utilized for the treatment of IBD potentially result in side effects that may resemble extraintestinal manifestations. This review provides a thorough analysis of the pathophysiology and treatment of extraintestinal manifestations associated with Crohn’s disease and ulcerative colitis.

Diverticulosis of the colon is the most frequent anatomical alteration diagnosed at colonoscopy. The prevalence of the disease is higher in elderly patients over 65 years old, recent studies show an increment also in youngers over 40 years old. Even its large prevalence in the population, its pathophysiology still remain poorly understood. It's widely accepted that diverticula are likely to be the result of complex interactions among genetic factors, alteration of colonic motility, lifestyle conditions such as smoking, obesity, alcohol consumption, fiber and meat intake with diet. Recently many authors considered also alterations in colonic microbiota composition, co-morbidity with diabetes and hypertension and the chronic assumption of certain medications like PPI, ARB and aspirin, as important risk factors for the development of diverticulosis. The aim of this narrative review is to summarise current knowledges on this topic.

Background: Endoscopic treatment of post-esophagectomy/gastrectomy anastomotic dehiscence includes Self-Expandable Metal Stents (SEMS), which have represented the “gold standard” for many years, and Endoscopic Vacuum Therapy (EVT), which was recently introduced, showing promising results. The aim of the study was to compare outcomes of SEMS and EVT in the treatment of post-esophagectomy/gastrectomy anastomotic leaks, focusing on oncologic surgery. Methods: A systematic search was performed on Pubmed and Embase, identifying studies comparing EVT versus SEMS for the treatment of leaks after upper gastro-intestinal surgery for malignant or benign pathologies. The primary outcome was the rate of successful leak closure. A meta-analysis was conducted, performing an a priori-defined subgroup analysis for the oncologic surgery group. Results: Eight retrospective studies with 357 patients were eligible. Overall, the EVT group showed a higher success rate (odd ratio [OR] 2.58, 95% CI 1.43–4.66), a lower number of devices (pooled mean difference [pmd] 4.90, 95% CI 3.08–6.71), shorter treatment duration (pmd −9.18, 95% CI −17.05–−1.32), lower short-term complication (OR 0.35, 95% CI 0.18–0.71) and mortality rates (OR 0.47, 95% CI 0.24–0.92) compared to stenting. In the oncologic surgery subgroup analysis, no differences in the success rate were found (OR 1.59, 95% CI 0.74–3.40, I² = 0%). Conclusions: Overall, EVT has been revealed to be more effective and less burdened by complications compared to stenting. In the oncologic surgery subgroup analysis, efficacy rates were similar between the two groups. Further prospective data need to define a unique management algorithm for anastomotic leaks.

Gastric cancer is, still nowadays, an important healthcare problem worldwide. In Italy, it represents the fifth tumour by frequency in both men and women over 70 years old. A crucial point is represented by the percentage of early gastric cancers usually found, which is actually very low, and it carries to a worse morbidity and mortality. The most important focus in this oncological disease, is to perform an effective detection of the most common precancerous lesion linked with this neoplasia, chronic atrophic gastritis, in order to avoid the future outcome of gastric cancer itself.

The manifestations of gastroesophageal reflux disease (GERD) have been recently classified into either esophageal or extra-esophageal syndromes. Clinical history, questionnaire data and response to antisecretory therapy are insufficient to make a conclusive diagnosis of GERD. Endoscopy had a low sensitivity. Recently, the availability of multichannel intraluminal impedance and pH-monitoring (MII-pH) has modified the diagnostic approach towards atypical manifestations of GERD. There is a rising consensus that this technique should be considered as the gold standard for GERD diagnosis. Gastrin 17 (G-17) has been proposed as a non-invasive marker of GERD, due to the negative feedback between acid and the hormone. G17 levels seem able to identify patients with acid and non-acid reflux.
