Abstract
PURPOSE The aim of this study was to define the values of percutaneous ultrasound shear-wave and strain elastography of the pancreas in healthy volunteers. METHODS This is a single-center prospective study conducted on volunteers who underwent examination of percutaneous point shear‑wave elastography and strain elastography. Both the shear-wave speed (Vs) and strain histogram were measured 3 times and median values were evaluated. Relevant recorded clinical data were age, sex, and height. RESULTS From May 2020 to October 2021 a total of 90 patients (21 male, 69 female) were included in the study. Their average age was 26 years (from 22 to 65). The average SWM in kPa was 6.07 (2.58-17.29). The average value of SE was 134.44 (78.51-184.35). Most of the patients had BMI in the range of normal weight with an average value of 22.75 (17.5-28). The average depth of the localization of the pancreas was 4.5 cm. The effect of BMI on the strain histogram was significant (p < 0.05). We found a significant relationship between the strain histogram and the depth of localization of the pancreas (p < 0.01). CONCLUSION We described normal values for pancreatic stiffness using ultrasound elastography by 2D-SWE and strain elastography. Our results indicate changes in values depending on BMI and depth of the pancreas. (Tab. 1, Fig. 5, Ref. 19).

Abstract
NTRODUCTION Distal pancreatectomy is a standard surgical procedure for selected benign, premalignant, and malignant lesions localized in the pancreatic body or tail. Surgical resection remains the only curative option for patients diagnosed with adenocarcinoma of the pancreas. PATIENTS AND METHODS Perioperative and postoperative clinical courses were retrospectively assessed in patients, who underwent distal pancreatectomy during the 2011‒2021 period. RESULTS During the 2011‒2021 period, a total of 112 distal pancreatectomies were performed. 67 patients (59.8%) underwent laparoscopic distal pancreatectomy, and 45 patients (40.2%) open laparotomy. The conversion was necessary for 13 patients (11.6%). Distal pancreatectomies performed laparoscopically were associated more often with biochemical leak and the development of grade B fistula, on the other hand grade C fistula developed only in patients operated by open laparotomy (LPT). The mean operating time was slightly longer in the laparoscopic group (227.1 min vs 214.6 min). The mean estimated blood loss was significantly higher in the LPT group (540.4 ml vs 191.9 ml). The mean hospitalization time was slightly longer in the LPT group (11.8 days vs 9.3 days). The rates of early reoperations were comparable between both groups (6 vs 5). CONCLUSION Laparoscopic techniques are preferred in centers around the world to bring patients benefits by using a minimally invasive approach. These techniques are also preferred in our center, in nearly 60% of all distal pancreatectomies performed during 10 years, but on the other hand, there is a much more careful approach chosen in cases of malignant disease to achieve adequate radicality (Tab.4, Ref. 20).

Abstract
The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has had a significant impact on the lives of millions of people, especially those with other concomitant diseases, such as chronic liver diseases. To date, seven coronaviruses have been identified to infect humans. The main site of pathological action of these viruses is lung tissue. However, a substantial number of studies have proven that SARS-CoV-2 shows affinity towards several organs, including the gastrointestinal tract and the liver. The current state of evidence points to several proposed mechanisms of liver injury in patients with COVID-19 and their combination. Liver impairment is considered to be the result of the direct effect of the virus on the hepatic tissue cells, a systemic reaction consisting of inflammation, hypoxia and cytokine storm, drug-induced liver injury, with the possible contribution of a perturbed gut-liver axis. Reactivation of chronic hepatic disease could be another factor for liver impairment in patients with SARS-CoV-2 infection. Acute-on-chronic liver failure (ACLF) is a relatively new syndrome that occurs in 10%–30% of all hospitalized patients with chronic liver disease. It is crucial to recognize high-risk patients due to the increased morbidity and mortality in these cases. Several published studies have reported virus infection as a trigger factor for ACLF. However, to date, there are few relevant studies describing the presence of ACLF in patients with acute SARS-CoV-2 infection. In this minireview we summarize the current state of knowledge regarding the relation between ACLF and acute SARS-CoV-2 infection.

Abstract
INTRODUCTION Insulinomas are rare neuroendocrine tumors of pancreas. Clinical manifestations include various symptoms of hypoglycemia, which is the result of insulin overproduction. Symptoms of hypoglycemia are heterogenous what most probably contributes to diagnostic delay. In this study we retrospectively evaluated clinical features of hypoglycemia. We discovered that a substantial number of patients suffered from hypoglycemia unawareness. MATERIALS AND METHODS We performed retrospective analysis of prospectively collected patients with histologically confirmed insulinoma. We evaluated clinical features and signs of hypoglycemia and the duration of symptoms and performed thorough review of the patients' files in order to identify whether patients had been falsely diagnosed previously. Each patient underwent 72 hour fasting test during which levels of immunoreactive insulin (IRI), C-peptide and nadir blood glucose level were obtained. Based on the clinical findings and results of 72 hour fasting test we identified a subgroup of patients with hypoglycemia unawareness. These had an episode of clinically silent hypoglycemia. We compared IRI and C-peptide levels obtained at the time of the fasting test termination in the unawareness group and the group without hypoglycemia unawareness. RESULTS Twenty two patients with insulinoma that had been hospitalized in our tertiary center were included in the analysis. Mean age was 51±16.7 years. The most common symptom reported by 63.6% of patients was fatigue, followed by increased appetite with consequent weight gain and the loss of consciousness, both reported by 40.9% of patients. Based on the review of clinical features and the results of the fasting test we identified a group of patients with hypoglycemia unawareness. We labeled the patient accordingly in case of the loss of consciousness in personal history as well as asymptomatic hypoglycemia or severe neuroglycopenic symptoms during the fasting test without any accompanying or preceding clinical signs. There were 7 patients with hypoglycemia unawareness in our cohort (31.8%). Patients with this phenomenon had significantly lower levels of both IRI (2.35±1.25 vs. 5.88±3.92ng/ml, p=0.01) and C-peptide (9.14±7.36 vs. 50±42.8 µU/ml, p=0.01) than the rest of the patients. Nadir blood glucose level during the fasting test showed no significant difference (9.4±8.2 vs. 12.2±8.2 months, p=0.28) in the unawareness group and the rest of the patients, respectively. CONCLUSION We described the phenomenon of unawareness to hypoglycemia in the patients with insulinoma. This has not been recognized in insulinoma patients yet since available evidence mostly relates to type I diabetic patients. It might lead to higher morbidity and diagnostic delay. Further studies with prospective evaluation should be performed to further confirm relatively high prevalence in patients with insulinoma.

Abstract
Dumping syndrome is a common post-operative complication following gastric surgery. Clinically, severe dumping can be a serious medical condition with a negative impact on the patient's life. In our case report, we present a case of refractory dumping syndrome which developed after laparoscopic subtotal gastrectomy with gastrojejunoanastomosis due to massive gastroptosis with stomach evacuation problems. Conservative gastroenterology treatment was not successful. Due to the progression of weight loss and life-threatening hypoglycaemia, the decision for surgical treatment was made. After the corrective gastro-duodenal and jejuno-jejunal anastomoses, all clinical symptoms resolved completely. With regard to the presented case, we discuss the common treatment options for dumping syndrome: the standard recommendations for dietary habits, pharmacological treatment and finally the surgery and its pitfalls. Due to the absence of randomized trials and guidelines, every patient should be treated in a personalized way.
