AIMTo investigate whether duodenal lesions induced by major venous occlusions can be attenuated by BPC 157 regardless nitric oxide (NO) system involvement.METHODSMale Wistar rats underwent superior anterior pancreaticoduodenal vein (SAPDV)-ligation and were treated with a bath at the ligated SAPDV site (BPC 157 10 μg, 10 ng/kg per 1 mL bath/rat; L-NAME 5 mg/kg per 1 mL bath/rat; L-arginine 100 mg/kg per 1 mL bath/rat, alone and/or together; or BPC 157 10 μg/kg instilled into the rat stomach, at 1 min ligation-time). We recorded the vessel presentation (filled/appearance or emptied/disappearance) between the 5 arcade vessels arising from the SAPDV on the ventral duodenum side, the inferior anterior pancreaticoduodenal vein (IAPDV) and superior mesenteric vein (SMV) as bypassing vascular pathway to document the duodenal lesions presentation; increased NO- and oxidative stress [malondialdehyde (MDA)]-levels in duodenum.RESULTSUnlike the severe course in the SAPDV-ligated controls, after BPC 157 application, the rats exhibited strong attenuation of the mucosal lesions and serosal congestion, improved vessel presentation, increased interconnections, increased branching by more than 60% from the initial value, the IAPDV and SMV were not congested. Interestingly, after 5 min and 30 min of L-NAME and L-arginine treatment alone, decreased mucosal and serosal duodenal lesions were observed; their effect was worsened at 24 h, and no effect on the collateral vessels and branching was seen. Together, L-NAME+L-arginine antagonized each other’s response, and thus, there was an NO-related effect. With BPC 157, all SAPDV-ligated rats receiving L-NAME and/or L-arginine appeared similar to the rats treated with BPC 157 alone. Also, BPC 157 in SAPDV-ligated rats normalized levels of NO and MDA, two oxidative stress markers, in duodenal tissues.CONCLUSIONBPC 157, rapidly bypassing occlusion, rescued the original duodenal flow through IAPDV to SMV flow, an effect related to the NO system and reduction of free radical formation.

There is no clinical evidence supporting the routine use of endoscopic staplers. The appendiceal stump can be secured safely with the use of endoloops in the majority of patients. Surgeons have to be more selective when choosing how to perform closure, and an endostapler should be used only in cases where it is clinically indicated.

The comprehensive approach demonstrated in this study enables correct differentiation of benign and malignant FLL in 96% of patients by using RT-2D-SWE.

Strong evidence supports the hepatoprotective effect of RIPC and LIPC preconditioning from an ischemia-reperfusion injury of the liver. Better synthetic liver function preservation in these two groups supports this conclusion.

Laparoscopic TAPP hernia repair has proven to be an efficient method for the treatment of groin hernias at our institution. Most patients can be treated as day-cases, namely they are hospitalized for 1 day, and they demonstrate a low recurrence rate (0.70%). Such low morbidity makes TAPP an attractive method for the routine treatment of groin hernias.

Introduction Despite some new treatment possibilities, the improvement in survival rate for hepatocellular carcinoma (HCC) patients is still poor due to late diagnosis. The aim of this study was to investigate the diagnostic sensitivity and specificity of protein induced by vitamin K absence or antagonist-II (PIVKAII), Glypican-3 (GP3), Cystatin B (CSTB), squamous cell carcinoma antigen 1 (SCCA1) and hepatocyte growth factor (HGF) as potential tumour markers for HCC in patients with alcoholic liver cirrhosis (ALC) using imaging techniques (MSCT and MRI) as reference standards. Patients and methods Eighty-three participants were included: 20 healthy volunteers, 31 patients with ALC and 32 patients with HCC. Peripheral blood sampling was performed for each participant, and serum concentrations of PIVKAII, GP3, CSTB, SCCA1 and HGF were determined using commercial ELISA kits. Results Only serum concentrations of PIVKAII were significantly higher in HCC patients as compared with ALC and healthy controls (cut-off: 2.06  µg/L; AUC: 0.903), whereas individual diagnostic performance of other individual compounds was inadequate. The 'best' combination of tumour markers in our study includes all tested markers with AUC of 0.967. Conclusion While novel diagnostic tumour markers are urgently needed, the examined potential tumour markers, with the exception of PIVKAII seem to be inadequate for diagnosing HCC in ALC. Furthermore, probably the future is in finding the best optimal combination of tumour markers for diagnosing HCC based on cost-effectiveness.

SUMMARY – The aim of the study was to explore predictive value of the ALBI, PALBI and MELD scores on survival in patients resected for hepatocellular carcinoma with compensated liver cirrhosis and no macrovascular infiltration. In this retrospective study, longitudinal survival analysis was performed. We analyzed patient/tumor characteristics and MELD, ALBI and PALBI scores as liver function tests for predicting survival outcome. Survival was analyzed from the date of liver resection until death, liver transplantation, or end of follow-up. Patients were stratified for age, cirrhosis etiology, presence of esophageal varices, hepatocellular carcinoma stage, microvascular invasion, histologic differentiation, and resection margins. We identified 38 patients (alcoholic cirrhosis in 84.2% of patients) resected over an 8-year period. Median preoperative MELD score was 8, ALBI score -2.63, and PALBI score -2.38. During the follow-up period, 24 patients died. Estimated median survival time was 36 months. Microvascular invasion was observed in 33 patients. Higher ALBI score was associated with 23.1% higher relative risk of death. PALBI score was associated with 12.1% higher relative risk of death, whereas MELD score was not associated with the risk of death. In conclusion, ALBI score demonstrated significant predictive capabilities for survival in patients with compensated cirrhosis resected for hepatocellular carcinoma.

Introduction and importance The falciform ligament is a peritoneal fold that extends from the anterior abdominal wall to the liver, which divides the liver into two lobes. Cysts of the falciform ligament are rare and without an apparent cause. The range of the symptoms can vary from abdominal pain to asymptomatic patients. Cysts are treated surgically, and resection is used to make a definitive diagnosis. Case presentation A 36-year-old female patient was treated at an outpatient facility for epigastric pain that lasted for three months. Abdominal MRI and MSCT were performed to verify a cyst formation in the left liver area of about 12 cm in size. Laparoscopic resection of the cist was performed under general endotracheal anaesthesia. Clinical discussion Falciform ligament tumours can be malignant or benign. Treatment of the cyst includes complete excision and pathohistological diagnosis to rule out malignancy. In most cases reported thus far, excision has been done after laparotomy. In our case, the operation was performed in a less invasive way, laparoscopically. Conclusion Laparoscopy can serve as a diagnostic and therapeutic method for cysts of the falciform ligament, both smaller and more significant, that infiltrate the surrounding structures.
