A 67-year-old man with previous cardiovascular disease was referred to our consultation due to a 5-month history of recurrent epigastric pain. Esophagogastroduodenoscopy and full blood workup presented no alterations. CT scan showed an irregularly shaped mass at the root of the mesentery, measuring 40x25x47mm, with spiculated contours and retractile behaviour (a). Simultaneous densification of the adjacent fat and infracentimetric ganglionic formations scattered throughout the mesentery were shown. Surgical biopsy revealed extensive storiform fibrosclerosis, with the presence of interstitial lymphoplasmocytic infiltrate and obliterative phlebitis (b); the plasma cells had mostly IgG expression, with IgG4:IgG ratio >40% (c), accounting for more than 30- 40 IgG4 plasma cells per field. The serum IgG4 level was 137mg/dL. A diagnosis of IgG4-related sclerosing mesenteritis was made, without other organ involvement. Prednisolone (0.6mg/kg/d) improved partially the abdominal pain, so steroid sparing strategy with off-label rituximab was associated. Due to its low prevalence, the understanding of this entity is scarce, and its diagnosis is challenging. Unlike other manifestations of IgG4-related disease, the intra-abdominal disease is identified in later stages, due to unspecific symptoms. This case aims to raise awareness about this condition as a differential diagnosis of abdominal pain.

Background and aims: In the presence of malignant dysphagia in non-surgical candidates, a self-expanding metal stent (SEMS) represents a safe and effective approach. Recently, a through-the-scope (TTS) SEMS was launched. The aim of our study was to assess the feasibility and safety of the TTS versus over-the-wire (OTW) SEMS in patients with malignant dysphagia.

Methods: This single-center retrospective cohort study included patients with malignant dysphagia undergoing esophageal TTS and OTW-SEMS from 2012 to May-2022. The primary outcomes were the technical and the clinical success of the SEMS placement. Secondary outcomes included adverse events, patency, and survival. Patients were prospectively followed until death or loss of follow-up.

Results: A total of 98 patients were enrolled, including 34 patients in the TTS group and 64 patients in the OTW group. TTS and OTW SEMS placement were feasible in 33 (97.1%) and 64 (100%) procedures , respectively (p=0.118). Overall, 32 patients (94.1%) in the TTS group and 62 patients (96.9%) in the OTW group showed an improvement in Ogilvie score (p=0.432). Recurrent dysphagia occurred in 30 patients, 12 in TTS group and 18 in OTW group, due to migration (4 vs. 5), stent deformation (1 vs. 1), tissue ingrowth (5 vs. 5) and overgrowth (2 vs. 7). No patient died from a stent-related cause. Median survival was 123 days (IQR: 59-209) in TTS group and 113 days (IQR: 73-271) in OTW group (p=0.349).

Conclusions: Placement of esophageal TTS and OTW stents resulted in similar technical and clinical outcomes, stent patency and survival in patients with malignant dysphagia.

Background and aims: Primary liver cancer (PLC) ranks among of the most common cancers worldwide. Within this group, a minority of cases displays characteristics of both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA), known as combined hepatocellular cholangiocarcinoma (cHCC- CCA). Currently, there is no specific standardized therapy for these mixed tumors. Therefore, the aim of our study was to analyze the clinical course, treatment and outcome of cHCC-CCA patients in a European population-based registry.

Methods: We investigated 9,144 patients with PLC (6,622 HCC, 2,356 iCCA, and 166 cHCC-CCA) diagnosed between 2009 and 2020. All data were obtained from Clinical Cancer Registry of Baden-Württemberg (BW), Germany.

Results: In all three groups patients were predominantly male (82%, 57%, and 68% for HCC, iCCA and cHCC-CCA groups, respectively). 48% of cHCC-CCA patients were diagnosed as stage IV cancers, which was more than for HCC (31%) but less compared to CCA (64%). Overall median survival of cHCC-CCA patients was worse compared to HCC (9-13 months vs. 15.5 months, p<0.001) and rather comparable to CCA (11.8 months).

Conclusions: Our data demonstrated that cHCC-CCA tumors appear to have a distinct clinical course with worse overall survival compared to HCC. Thus, identification of these cancers by histopathology is essential in order to further characterize this tumor entity and to provide accurate treatment to these patients.

Background and aims: In the last years increasing scientific evidence drew attention on the potential effects of anesthetic drugs on postoperative outcome in cancer patients. Local anesthetics, especially lidocaine, have been intensively studied in relation with postoperative outcome in colorectal cancer patients. Our study objectives were to investigate the effects of perioperative intravenous lidocaine infusion on neutrophil-to-lymphocyte ratio and short-term postoperative outcome. Additionally, we also looked at 1 year outcome after intended radical colorectal cancer surgery.

Methods: 150 patients scheduled for colorectal cancer surgery were randomized to receive sevoflurane anaesthesia with or without 48 hours lidocaine infusion.

Results: 73 patients were included in the group A (sevoflurane) and 77 in the group B (sevoflurane with lidocaine). Lidocaine infusion did not modify neutrophil-to-lymphocyte ratio at 24 hours after surgery (p=0.58). Patients receiving intravenous lidocaine had significantly lower morphine consumption (p=0.04), faster mobilization time (p=0.001) and fewer days spent in the hospital (p=0.04). Moreover, at 1 year follow- up, patients in group B had a significant decreased rate of recurrences (p=0.03). There was no significant difference in 1 year survival (p=0.22).

Conclusions: In our study, intravenous lidocaine infusion hastened the postoperative recovery of patients in terms of mobilization, hospital discharge and opioid consumption and reduced 1 year recurrence rate. Further studies on larger groups of patients are needed.

Irritable bowel syndrome (IBS) is a common chronic functional gastrointestinal disorder defined by disturbances in bowel habits and abdominal pain, in the absence of known organic pathology that affects between 5 to 10% of healthy populations. Despite improvements in detection and treatment, the pathogenesis of IBS has not been clarified. Several microRNAs (miRNAs) are involved in the pathogenesis of IBS through increased intestinal permeability, inflammation, and modulation of visceral hyperalgesia, and they may have the potential to be used as biomarkers and therapeutic targets. Here, we have summarized the recent advances about the role of miRNAs in the development of IBS symptoms and the possibility to use them as therapeutic targets to mitigate symptoms in IBS.

Aims: To compare the effectiveness and safety of transarterial chemoembolization (TACE) combined with apatinib plus camrelizumab (TACE+AC) versus TACE combined with apatinib alone (TACE+A) for patients with advanced HBV-related hepatocellular carcinoma (HBV-HCC).

Methods: The clinical data of patients with HBV-HCC who received either TACE+AC or TACE+A treatment were retrospectively analyzed. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and adverse events (AEs) were compared between the two groups. Multivariate Cox proportional hazards model regression analysis was used to identify the independent prognostic factors of OS.

Results: Between March 2019 to January 2022, 76 patients were assigned to the TACE+AC group (n = 37) and the TACE+A group (n=39). The median OS and PFS in the TACE+AC group were significantly longer than those in the TACE+A group (OS, 15.4 vs. 11.3 months; p=0.008; PFS, 7.4 vs. 5.1 months; p=0.001) and the ORR and DCR in the TACE + AC group were significantly greater than those in the TACE+A group (ORR, 43.2% vs. 20.5%; p=0.033; DCR, 67.6% vs. 43.6%; p=0.036). There was no significant difference in the incidence of grade ≥3 AEs between the two groups (p=0.483). Multivariate regression analysis identified the treatment modalities, AFP level, and extrahepatic metastasis as independent prognostic factors (p<0.05).

Conclusion: TACE+AC significantly improved the clinical outcomes of patients with HBV-HCC and elicited relatively controllable AEs.

Background and aims: Transjugular intrahepatic portosystemic shunt (TIPS) is often used in patients with cirrhosis to manage portal hypertension-related complications. Unfortunately, 35-50% of patients develop overt hepatic encephalopathy (HE) after TIPS. However, data on lactulose and rifaximin to prevent post-TIPS HE is limited. Therefore, we aimed to perform a network meta-analysis to investigate the efficacy of multiple pharmacological regimens in the prevention of post-TIPS HE.

Methods: A comprehensive search strategy to identify reports of studies of rifaximin use on post-TIPS hepatic encephalopathy was constructed using truncated keywords, phrases, and subject headings developed in Embase. This strategy was translated to MEDLINE, Cochrane Central Register of Controlled Trials, and the Web of Science Core Collection, with all searches performed on 10 February 2022. No publication date or language limits were used.

Results: The initial search identified 72 studies, and 56 studies were screened after removing duplicates. Five studies, two randomized controlled trials (RCTs) and three retrospective studies, met our inclusion criteria and were included in the final analysis. A total of 840 patients were included, with 65% male. Our meta- analysis did not find a statistically significant difference between lactulose vs placebo/no prophylaxis, nor rifaximin vs placebo/no prophylaxis, nor rifaximin plus lactulose vs placebo/no prophylaxis in the reduction of post-TIPS HE.

Conclusions: Rifaximin alone, lactulose alone, and rifaximin plus lactulose did not significantly reduce the development of post-TIPS HE. Based on the P-scores of the three treatment groups, the combination of rifaximin plus lactulose showed the most promising trend towards preventing post-TIPS HE. More studies, especially large RCTs, are warranted.
