Quantification of hemi-hepatic ischemia using real-time multispectral oxygenation imaging with single snapshot imaging of optical properties (SSOP).

Background: Identifying liver ischemia is crucial in liver surgery. This study aimed to develop a hemi-hepatic ischemia model for assessing liver ischemia using single snapshot imaging of optical properties (SSOP), a noninvasive optical imaging modality that provides real-time measurements of tissue oxygen saturation (StO2).

Materials And Methods: Twelve swine were randomly assigned to two groups: One undergoing total vascular inflow occlusion (TVIO) and the other undergoing hepatic artery occlusion (HAO).

Comparing perspectives: frontal and oblique endoscopic ultrasound.

The oblique-view echoendoscope is currently the sole tool for ultrasound-guided endoscopic procedures (EUS) in most hospital centers, despite its limitations like a lack of forward vision, issues with needle angle, and restricted accessory device size due to channel angulation. However, our study revealed no significant differences between the oblique and frontal endoscopes, except for minor variations in specific regions. For routine diagnostic studies, interchangeability between the devices is feasible.

Colorectal Cancer and Polyp Detection Using a New Preparation-Free, Colon-Scan Capsule: A Pilot Study of Safety and Patient Satisfaction.

Background: Current strategies to prevent colorectal cancer (CRC) vary considerably regarding safety, invasiveness, and patient satisfaction. A known deterrent for patients is the required bowel cleansing for colonoscopy. A new colon-scan capsule system is a unique preparation-free approach that provides structural information on colonic mucosa intended for detection of colorectal polyps and masses.

Outcomes of endoscopic ultrasound and endoscopic resection of gastrointestinal subepithelial lesions: a single-center retrospective cohort study.

Background: Endoscopic resection (ER) is an emerging therapeutic alternative for subepithelial gastrointestinal lesions (SELs). We aimed to determine whether size, layer of origin, and histology based on endoscopic ultrasound (EUS) and EUS-guided sampling (EUS-GS) influenced the outcomes and selection of patients for ER.

Methods: We performed a retrospective review of patients who underwent EUS, EUS-GS and resection of SELs from 2012-2019.

Step-by-step instruction: using an endoscopic tack and suture device for gastrointestinal defect closure.

Training, Reading, and Reporting for Small Bowel Video Capsule Endoscopy.

Video capsule endoscopy (VCE) is an established modality for examining the small bowel. Formal training in interpretation and reporting of VCE examinations, along with assessment of performance metrics, is advocated for all gastroenterology fellowship programs. This review provides an overview of VCE minimum training requirements and competency assessment, cognitive and technical aspects of interpretation, and standardized reporting of findings.
