A novel reopenable clip with sharp claw for complete closure of mucosal defects after colorectal endoscopic submucosal dissection.

Background: The MANTIS Closure Device (MCD; Boston Scientific, Marlborough, Massachusetts, USA) is a reopenable clip with a sharp claw used for closure after endoscopic submucosal dissection (ESD). We evaluated the effectiveness of the MCD for fast and complete closure after colorectal ESD.

Methods: Cases involving closure with the MCD after ESD of 20-60-mm colorectal lesions between April 2023 and January 2024 were reviewed.

Practical approach to linear endoscopic ultrasound examination of the gallbladder.

The gallbladder (GB) is a susceptible organ, prone to various pathologies that can be identified using different imaging techniques. Transabdominal ultrasound (TUS) is typically the initial diagnostic method due to its numerous well-established advantages. However, in cases of uncertainty or when a definitive diagnosis cannot be established, computed tomography (CT) or magnetic resonance imaging may be employed to provide more detailed information.

Inflammatory bowel disease evolution in the past two decades: a chronological multinational study.

Background: The multifactorial nature of inflammatory bowel disease (IBD), which manifests differently in individuals creates a need for a better understanding of the behaviour and pattern of the disease due to environmental factors. The current study aimed to study the changes in IBD behaviour, presentation, and characteristics in patients over the past two decades with a goal of improving patients' diagnosis, management and outcomes.

Methods: During a 6-month period (1/02/2022-30/07/2022), the information of patients with IBD who attended IBD outpatient clinics of 11 referral centre's in six countries was collected, and based on the first time of diagnosis with IBD, they were allocated as group A (those who were diagnosed more than 15 years ago), group B (those who were diagnosed with IBD between 5 and 15 years ago) and group C (IBD cases who diagnosed in recent 5 years).

Role of endoscopic ultrasound in the characterization of solid pseudopapillary neoplasm of the pancreas.

Background: Solid pseudopapillary neoplasm (SPN) is an uncommon pathology of the pancreas with unpredictable malignant potential. Endoscopic ultrasound (EUS) assessment plays a vital role in lesion characterization and confirmation of the tissue diagnosis. However, there is a paucity of data regarding the imaging assessment of these lesions.

Endoluminal ultrasound versus magnetic resonance imaging in assessment of rectal cancer after neoadjuvant therapy.

Background: Accurate rectal tumor staging guides the choice of treatment options. EUS and MRI are the main modalities for staging.

Aim Of The Work: To compare the performance of EUS and MRI for loco-regional staging of anorectal cancer after neo-adjuvant therapy.

Safety and efficacy of endoscopic ultrasound as a diagnostic and therapeutic tool in pediatric patients: a multicenter study.

Background: Despite the well-established diagnostic and therapeutic applications of endoscopic ultrasound (EUS) in adults, data about its use in children are limited. In this study, we tried to assess the feasibility, safety, and clinical impact of EUS in pediatric patients.

Methods: Data of pediatric patients (<18 years) referred for EUS over a 3-year period to the endoscopy units of four Egyptian tertiary centers were retrospectively analyzed.

Technical and Clinical Outcomes of Using a Single Wide-Caliber Double-Pigtail Stent for Endoscopic Ultrasound-Guided Pancreatic Pseudocyst Drainage: A Multicenter Prospective Study.

Introduction: Endoscopic ultrasound (EUS)-guided pancreatic cysto-gastrostomy/duodenostomy is the current accepted practice for management of symptomatic pancreatic pseudocysts with insertion of two or more double-pigtail (DP) stents. There is no much work on the efficacy of using a single wide-caliber DP stent, aiming to decrease the time, complications, and accessories used in the procedure.

Aim Of The Work: The aim of this study was to assess technical and clinical outcomes of using a single wide-caliber DP stent in EUSguided pancreatic pseudocyst drainage.

Clinico-Epidemiological Characteristics of Patients With Inflammatory Bowel Disease in Egypt: A Nationwide Multicenter Study.

Background And Aims: Ulcerative colitis (UC) and Crohn's disease (CD) are the most common types of Inflammatory bowel disease (IBD), with variable responses to traditional therapies and unpredicted prognosis. In Egypt and most developing countries, the lack of recent epidemiological and prognostic data adversely affects management strategies. We collected and analyzed data of patients with IBD from multiple centers across Egypt to evaluate patients' clinical and epidemiological characteristics.

Association of TNF-α G-308 a Promoter Polymorphism with the Course and Outcome of COVID-19 Patients.

Background: Tumor necrosis factor-ɑ (TNF-ɑ) is one of the most important cytokines that manage the host defense mechanism, which may play a role in the pathogenesis of COVID-19 patients. The work aims to study the association of TNF-ɑ G-308 A gene polymorphism with the course and outcome of COVID-19 patients in Mansoura University Hospital.

Methods: 900 patients with COVID-19 infection and 184 controls were tested for TNF-ɑ G-308 A promoter polymorphism.

Chronic Hepatitis C Patients with Obesity: Do we Need two Operators for Accurate Evaluation of Liver Stiffness?

Introduction And Aim: Transient elastography is gaining popularity as a non-invasive method for predicting liver fibrosis, but inter observer agreement and factors influencing reproducibility have not been adequately assessed.

Material And Methods: This cross-sectional study was conducted at Specialized Medical Hospital and the Egyptian Liver Foundation, Mansoura, Egypt. The inclusion criteria were: age older than 18 years and chronic infection by hepatitis C.

Resection of rectal GIST using a novel technique: a report of two cases.

Rectal gastrointestinal stromal tumours (GISTs) are uncommon tumours and usually present with large sizes. We present two cases of rectal GIST. Imatinib was used in the setting of neoadjuvant and adjuvant therapy.
