RESUMEN
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 2011â2021 period. RESULTS: During the 2011â2021 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).

Introduction: Benign lesions of the liver are very common findings, usually randomly discovered, especially during examinations for other indications. The frequent use of imaging modalities may be responsible for the statistical increase in the incidence of these findings. Case Presentation: In this publication, we present the cases of 2 female patients with benign liver lesions, the occurrence of which is considered rare, and only a few dozen cases have been described worldwide. In both cases, clinical symptoms, diagnostic approach, and surgical treatment are presented. Conclusion: Due to increasing availability of imaging methods, the occurrence of previously considered rare benign liver lesions increases as well. In many cases, the malignant potential of these findings remains unclear. Decision-making process should include a multidisciplinary board.
RESUMEN
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 shearwave 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).

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.
RESUMEN
Rupture of the spleen is a serious medical condition manifesting as a sudden abdominal event, potentially life-threatening. Spontaneous spleen rupture is a rare condition. Atraumatic rupture of the spleen is a very unlikely condition. Risk factors include splenomegaly, hemato-oncological diseases, and infections, such as malaria or infectious mononucleosis. Extremely rare is splenic rupture described in autoimmune disease or vasculitis. There has been no reported case of spontaneous splenic rupture as a first manifestation of Churg- Strauss syndrome so far.

Insulinoma is a rare functional neuroendocrine tumor of pancreas. The only recommended treatment is surgical removal. We present a case of a 46-year-old female patient who underwent the enucleation of insulinoma localized nearby pancreatic main duct after preoperative endoscopic insertion of pancreatic stent. The tumor was safely identified during the surgery and was enucleated without injury of pancreatic duct or postoperative complications.
RESUMEN
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.
RESUMEN
Mixed connective tissue diseases (MCTD) is a very rare autoimmune disease connecting clinical signs of systemic lupus, systemic sclerosis, polymyositis and rheumatoid arthritis. Clinical manifestations are very diverse. In some patients, the digestive tract is affected in varying degrees. The esophagus is affected most often, and patients are complaining of dysphagia. Morphologically, this disorder is similar to the injure in systemic scleroderma. In this case, we describe a unique case of a severe damage of digestive tract manifested by esophageal motility disorders, cachectization, ascites, and repeated ileus conditions.

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.

BACKGROUND: Several studies demonstrated that proton pump inhibitors (PPIs) co-administrated with dabigatran in patients with atrial fibrillation (AF) decreased dabigatran trough and peak plasma levels. However, it is still unknown whether this interaction is reversible or not, and whether the withdrawal of PPI would lead to normalization of dabigatran plasma levels. AIM OF STUDY: The aim of this study was to determine the effect of PPI withdrawal on dabigatran plasma levels in patients with AF. METHODS: This pilot prospective study enrolled 23 AF patients on long-term dabigatran and PPI therapy (omeprazole 20 mg twice daily or pantoprazole 40 mg once daily). Dabigatran trough and peak levels (ng/mL) were tested on PPI and after a 2-week period of PPI withdrawal with Hemoclot Thrombin Inhibitor Assay. RESULTS: The analysis of dabigatran plasma levels demonstrated significant elevation in trough dabigatran levels after 2 weeks of PPI withdrawal (97.2 ± 79.7 vs. 163.8 ± 105.5 ng/mL; P < 0.05). Moreover, significantly higher peak dabigatran levels were observed after 2 weeks of PPI withdrawal (142.4 ± 102.8 vs. 255 ± 129.5 ng/mL; P ≤ 0.001). CONCLUSIONS: This study showed that a 2-week period of PPI withdrawal lead to a significant increase in dabigatran trough and peak plasma levels in patients with AF.

The sensitization of cough reflex observed in patients with gastroesophageal reflux disease (GERD) is attributed to activation of vagal C-fibers innervating the esophagus by acid, while the heartburn in GERD is mediated by esophageal acid sensitive C-fibers derived from (dorsal root ganglia) DRG. Here we explored the relationship between cough reflex sensitivity (CRS) and esophageal sensitivity to acid. We evaluated CRS to capsaicin inhalation and esophageal sensitivity to acid (intensity of heartburn evoked by esophageal infusions of acid pHâ¯=â¯3, 2 and 1) in patients with GERD and chronic heartburn before and 3 months after proton pump inhibitor (PPI) treatment. There was no correlation between CRS and esophageal sensitivity to acid at any pH tested. PPI treatment substantially reduced esophageal sensitivity to acid but did not affect CRS. We conclude that a simple direct relationship between CRS and esophageal sensitivity to acid is unlikely. The results indicate that spinal and vagal afferent pathways from the esophagus are probably influenced separately in subjects with GERD.
