Purpose: The proximal anastomosis of free right internal thoracic artery to ascending aorta is technically difficult when the caliber is not enough.
Methods: We incise the proximal stump of the graft longitudinally for 10 mm. One side of start point of longitudinal incision is sewn to the end point of incision by 7-0 polypropylene. The folded sideline (5 mm length) is then closed with a running suture, then formation of pouch like anastomotic end is accomplished.
Results: We used this technique in consecutive 34 patients who underwent coronary artery bypass surgery including revascularization to circumflex arteries. Postoperative angiography revealed 97% patency. It does not need another graft material like saphenous vein or radial artery, and possible not only in on pump surgery but also in off pump.
Conclusion: This new "Pouch technique" will make it easy to use right internal thoracic artery as a free graft in coronary artery bypass surgery.

Introduction: Biliary tract cancer (BTC) comprises a clinically diverse and genetically heterogeneous group of tumors along the intra- and extrahepatic biliary system (intrahepatic and extrahepatic cholangiocarcinoma) and gallbladder cancer with the common feature of a poor prognosis, despite increasing molecular knowledge of associated genetic aberrations and possible targeted therapies. Therefore, the search for even more precise and individualized therapies is ongoing and preclinical tumor models are central to the development of such new approaches.
Areas Covered: The models described in the current review include simple and advanced in vitro and in vivo models, including cell lines, 2D monolayer, spheroid and organoid cultures, 3D bioprinting, patient-derived xenografts, and more recently, machine-perfusion platform-based models of resected liver specimens.
Risk factors analysis of hypokalemia after radical resection of esophageal cancer and establishment of a nomogram risk prediction model.

Objective: This study aimed to explore the risk factors of hypokalemia after radical resection of esophageal cancer (EC) and establish a nomogram risk prediction model to evaluate hypokalemia risk after esophagectomy. Thus, this study provides a reference for the clinical development of intervention measures.
Methods: Clinical data of EC patients who underwent radical surgery from January 2020 to November 2022 in the First Affiliated Hospital of Guangxi Medical University were retrospectively collected.
Type B Aortic Dissection Secondary to Non-typhoidal Salmonella Aortitis: A Case Report and Literature Review.
J Community Hosp Intern Med Perspect

Department of Nursing, Karnali Academy of Health Science, Jumla, Nepal.
Infectious aortitis is an uncommon but potentially fatal condition that can lead to aortic dissection or rupture. We describe a case of a 69-year-old female who developed a Stanford type B aortic dissection, presumptively caused by Salmonella, which was successfully managed with thoracic endovascular aneurysm repair (TEVAR) and long-term antibiotics. A literature review of 17 reported cases from 2000 to 2024 of aortic dissection secondary to infectious aortitis was conducted.

Background: Deep learning (DL)-based adipose tissue segmentation methods have shown great performance and efficacy for adipose tissue distribution analysis using magnetic resonance (MR) images, an important indicator of metabolic health and disease. The aim of this study was to evaluate the reproducibility of whole-body adipose tissue distribution analysis using proton density fat fraction (PDFF) images at different MR strengths.
Methods: A total of 24 volunteers were imaged using both 1.
