We aimed to perform a comprehensive prospective histological analysis in a cohort of 40 inflammatory bowel disease (IBD) patients, both prior to and during biological therapy. The main objective was to establish the impact of histological activity in assessing treatment response and therapy guidance. Biopsy samples were assessed in two different stages of the disease course - before introduction of biological therapy and during follow-up (6-12 months later).

Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is a promising tool for pNETs, with a good safety profile and favorable results.
Patients, Materials And Methods: This is a single-center, retrospective case series including all patients with functional (F) and non-functional (NF) pNETs treated with EUS-RFA in the Department of Gastroenterology, Emergency Clinical Hospital of Bucharest, Romania, between March 2023 and March 2024 and followed for a mean period of 11.

Globally, cancer is the leading cause of mortality, with colorectal neoplasia ranking third in terms of incidence and mortality worldwide. Patients face disease- and treatment-specific impacts, which can significantly influence their quality of life (QoL). Aim: This study aimed to propose a protocol to measure in-hospital and long-term QoL in patients with complicated colorectal cancer (CRC).

Cholangiocarcinoma (CCA) is an adenocarcinoma originating from the epithelial cells of the bile ducts/hepatocytes or peribiliary glands. There are three types of cholangiocarcinoma: intrahepatic, perihilar and distal. CCA represents approximately 3% of the gastrointestinal malignancies.

Today, these materials mostly remain interesting objects for in-depth fundamental studies and scientific curiosity due to issues related to their preparation and environmental stability, limiting potential industrial applications. This work proposes a simple and inexpensive concept of composite electrodes composed of molybdenum- and titanium-containing MAX phases and MXene as functional materials.

Endoscopic remission had been the most significant endpoint target in the last years; nevertheless, a remarkable proportion of patients continue to relapse despite a normal-appearing mucosa, highlighting that endoscopy may underestimate the true extent of the disease. A subtle hint of the importance that histology plays in the long-term course of the disease has been endorsed by the STRIDE-II consensus, which recommends considering histologic healing for ulcerative colitis (UC), even though it is not stated to be a compulsory formal target.

Peri-pancreatic fluid collections are late complications of acute pancreatitis. Loculated peri-pancreatic fluid collections, even rare, remain the "black sheep" in terms of drainage, due to difficulty to puncture all compartments, thus prohibiting proper drainage of all compartments. Recombined tissue plasminogen activator (r-tPA) has been advocated as treatment of the loculated collections, due to its ability to dissolve the fibrinous strands and thus facilitate proper drainage.

Nevertheless, the rate of surgery is still at a very high rate, profoundly affecting the quality of life. We aimed to analyze surgical cases at three major IBD units in order to identify the main risk factors and the impact of biologic therapy on pre- and postsurgical outcomes.

Artificial intelligence (AI) is a term that covers a multitude of techniques that are used in a manner that tries to reproduce human intelligence. AI is helpful in various medical specialties that use imaging for diagnostic purposes, and gastroenterology is no exception. In this field, AI has several applications, such as detecting and classifying polyps, detecting the malignancy in polyps, diagnosing Helicobacter pylori infection, gastritis, inflammatory bowel disease, gastric cancer, esophageal neoplasia, and pancreatic and hepatic lesions.

The development and progression of colorectal cancer (CRC) have been associated with inflammation processes that involve the overactivation of the NF-κB signalling pathway. The characterization of the NF-κB expression profile in CRC is an important topic since the suppression of NF-κB represents a potential therapeutic approach. In this study, we assessed the expression levels of 84 NF-κB-related genes in paired tumoral (T) and peritumoral (PT) tissues from 18 CRC patients and 18 normal colonic mucosae, and the expression levels of three miRNAs targeting the most dysregulated genes revealed by the case-control analysis.

Background: Cholangiocarcinoma is the most common malignancy of the bile ducts causing intrahepatic, hilar, or distal bile duct obstruction. Most jaundiced patients are diagnosed with unresectable tumors in need for palliative bile duct drainage and chemotherapy. Endobiliary radiofrequency ablation (RFA) is an adjuvant technique that may be applied prior to biliary stenting.

Background and Aim. Endoscopic therapy is the method of choice in the management of biliary strictures after orthotopic liver transplantation (OLT). Even though the mainstay approach for OLT stricture complications is represented by consecutive procedures of multiple plastic stents (MPS) insertion, a valuable alternative is the use of fully covered self-expandable metal stents (FCSEMS).

Microelectromechanical systems (MEMS) have been increasingly used worldwide in a wide range of applications, including high tech, energy, medicine or environmental applications. Magnetic polymer composite films have been used extensively in the development of the micropumps and valves, which are critical components of the microelectromechanical systems. Based on the literature survey, several polymers and magnetic micro and nanopowders can be identified and, depending on their nature, ratio, processing route and the design of the device, their performances can be tuned from simple valves and pumps to biomimetic devices, such as, for instance, hearth ventricles.

Acute pancreatitis (AP) represents a major burden for the medical system, associating important morbidity and mortality rates. This paper is focused on debatable aspects of the management of biliary AP, namely indications, timing and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) on the hand and, on the other hand, same-admission cholecystectomy as a preventive measure for recurrent disease. Material and methods: This is a retrospective study including 108 patients with biliary AP in whom ERCP was performed, treated in the Clinical Emergency Hospital of Bucharest between 2016 and 2020.

Objective: The purpose of this study was to present the experience of a single center on endoscopic ultrasound-fine-needle biopsy (EUS-FNB) of pancreatic solid tumors amenable to immunohistochemistry (IHC) assay.
Patients, Materials And Methods: Inclusion criterion for this prospective study was identifying patients with pancreatic solid tumors, by means of imaging methods, from January 2018 to February 2020, within the Department of Gastroenterology, Emergency Clinical Hospital, Bucharest, Romania. All patients underwent EUS-FNB and the harvested tissue was sent to the Department of Pathology for histopathological (HP) diagnosis and IHC assessment if tumoral origin remained undetermined.
Introduction: Pancreatic malignancies represent highly fatal diseases with poor prognosis and constantly increasing incidence despite modern diagnostic and therapeutic options. Both endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are regarded as mainstays in pancreatic cancer management. The present study aims to evaluate whether accuracy EUS with fine-needle aspiration or biopsy (FNA or FNB) in pancreatic cancer diagnosis is influenced by prior biliary stenting or by technical or anatomical features (stent type, number of needle passes, common bile duct or Wirsung's diameter, topographical characteristics and diameter of the pancreatic tumor).
