Ultrasound-guided drainage is the first-line modality for drainage of symptomatic of pancreatic fluid collections. In the context of pancreatic cancer, use of multiple double-pigtail plastic stents suffice, with high treatment efficacy. This approach provides similar success rates with low complications and better quality of life compared with surgery. Lumen apposing metallic stents (LAMSs) permit more effective drainage with larger diameter; because of their higher costs than plastic stents, their main role is probably in the context of walled-off necrosis, but the place and the use of LAMS should be studied to avoid and reduce the risks of complications...

New applications of confocal laser endomicroscopy (CLE) have been developed, such as needle-based CLE (nCLE) for pancreatic masses, pancreatic cystic tumors, and lymph nodes. nCLE is feasible during endoscopic ultrasound (EUS) examination, and preliminary results are very encouraging and suggest this technology may be used in future as a useful adjunct in cases of inconclusive EUS-guided fine-needle aspiration. The aim of this paper is to give an update in this new technology and to define its place in the diagnosis of pancreatic masses and mediastinal diseases...

Endoscopic ultrasound (EUS)-guided drainage is now the treatment of choice in cases of pancreatic pseudocysts and walled-off necrosis, especially in the absence of luminal bulging and in patients with portal hypertension. Malignant refractory ascites usually heralds a poor prognosis and substantially impairs the quality of life of patients because of the symptoms experienced and the need for repeated paracentesis. EUS-guided placement of lumen-apposing, fully covered, self-expandable metal stents (FCSEMS) has been reported for the drainage of malignant ascites...

Preclinical models based on patient-derived xenografts have remarkable specificity in distinguishing transformed human tumor cells from non-transformed murine stromal cells computationally. We obtained 29 pancreatic ductal adenocarcinoma (PDAC) xenografts from either resectable or non-resectable patients (surgery and endoscopic ultrasound-guided fine-needle aspirate, respectively). Extensive multiomic profiling revealed two subtypes with distinct clinical outcomes. These subtypes uncovered specific alterations in DNA methylation and transcription as well as in signaling pathways involved in tumor-stromal cross-talk...

BACKGROUND: Currently, colonoscopy and polypectomy are the gold standard methods for the prevention of incident cases of colorectal cancer. The use of a new colonoscope (Fuse(®), EndoChoice(®)) with a larger view of up to 330° appears to improve the adenoma detection rate (ADR). We performed a prospective observational study concerning this scope. The primary endpoint was potentially omitted adenomas (POA), i.e. adenomas seen on the side screens that will not appear on the central display during colonoscopy withdrawal without oriented movements...

Pancreatic adenocarcinoma represents the fourth most common cause of cancer mortality and death due to pancreatic cancer (PC) have increased since 2003. Its incidence has also raised about 30% in the past decade and it is expected to become the second cause of cancer mortality by 2020 in the USA. Most PC present with metastatic disease and improvements in treatment outcomes for this group have been disappointing. These observations support the idea that screening to identify patients at an earlier stage might be an important strategy in improving overall PC outcomes...

BACKGROUND AND OBJECTIVES: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) represents an option to treat obstructive jaundice when endoscopic retrograde cholangiopancreatography (ERCP) fails. The success rate of this procedure has been shown to be very high. Up to now, plastic and self-expandable metallic stents (SEMSs) have been employed, each of them presenting some limitations. The aims of this study were to evaluate the technical and functional success rates of EUS-HGS using a dedicated biliary SEMS with a half-covered part (Giobor® stent)...

BACKGROUND: Cytomegalovirus (CMV) infection remains one of the most common and feared complications of transplantation, justifying prophylaxis or preemptive strategies guided by donor and recipient CMV serostatus. In case of seronegative donor and recipient (D-/R-), no prophylaxis is recommended. Late-onset CMV disease is usually defined as occurring after prophylaxis discontinuation in D+/R- transplant patients. CASE PRESENTATION: We are reporting the case of a D-/R- kidney Caucasian transplant recipient presenting with CMV primoinfection 12 years after renal transplant, and discuss the role of a secondary prophylaxis so late after transplantation...

BACKGROUND: Endoscopic management of Barrett's esophagus (BE) depends on the histological stage of BE and includes the following: follow up, endotherapy with thermal ablation, and piecemeal or monobloc endoscopic resection (ER). We know that biopsies are unreliable in 20-75% of cases. The aim of our study was to evaluate the efficiency of probe confocal laser endomicroscopy (pCLE) in the diagnosis of the histological stage of BE, compared with the final histological results after ER. METHODS: This retrospective study was based on a prospective registry of patients referred for management of BE-associated dysplasia...

c-MYC controls more than 15% of genes responsible for proliferation, differentiation, and cellular metabolism in pancreatic as well as other cancers making this transcription factor a prime target for treating patients. The transcriptome of 55 patient-derived xenografts show that 30% of them share an exacerbated expression profile of MYC transcriptional targets (MYC-high). This cohort is characterized by a high level of Ki67 staining, a lower differentiation state, and a shorter survival time compared to the MYC-low subgroup...
