Abstract We present here the three-dimensional (3D) visualization fused with ultrasound and to evaluate its clinical application effect preliminarily. One hundred and eighteen patients with renal calculi in our hospital from September 2017 to December 2019 were prospectively randomized into two groups. The experimental group was treated with percutaneous renal puncture guided by the 3D visualization fused with ultrasound. The control group was treated with percutaneous renal puncture guided by B-ultrasonography (B-US). The puncture time, operation time, and the loss of hemoglobin in the experimental group were lower than those in the control group, and the success rate of establishing the channel at one time, and the coincidence rate between the channel and the longitudinal axis of the target renal calyx were higher. The stone clearance rate in the experimental group was higher, while the postoperative blood transfusion rate and interventional embolization rate in the experimental group were significantly lower. The difference was statistically significant (P < 0.05). 3D visualization assisted ultrasound could preliminarily guide precise navigation to puncture tissues, reduced operation time and bleeding, improved stone clearance rate and operation safety.

The objective of this study is to retrospectively evaluate factors significantly contributing to a failed stone extraction (SE) in patients with difficult to extract bile duct stones (BDS). Patients and Methods. During a 10-year period 1390 patients with BDS underwent successfully endoscopic sphincterotomy. Endoscopic SE was graded as easy; relatively easy; difficult; and failed. Difficult SE was encountered in 221 patients while failed SE was encountered in 205. A retrospective analysis of the criteria governing the difficulty of endoscopic SE following the index endoscopic intervention was performed to evaluate their significance in determining failure of complete SE among patients with difficult to extract bile duct stones. Results. Age ≥ 85 years, periampullary diverticula, multiple CBD stones (>4), and diameter of CBD stones (≥15 mm) were all significant contributing factors to a failed SE in univariate statistical tests. In the definitive multivariate analysis age, multiple stones and diameter of stones were found to be the significant, independent contributors. Conclusion. Failed conventional endoscopic stone clearance in patients with difficult to extract BDS is more likely to occur in overage patients, in patients with multiple CBD stones >4, and in patients with CBD stone(s) diameter ≥15 mm.

With the development of science and technology, there are constantly new technologies used in medicine, and related medical technologies have also been greatly improved. Anatomy is one of them. This technology has been widely used in clinical practice, but traditional anatomy is evaluated before surgery. There shortcomings, and it is impossible to have a more accurate understanding of the disease. Therefore, improper operation may still cause some problems during the operation, such as bile duct and blood vessel damage, organ failure and other adverse consequences. Duodenum and its surrounding organs are a complex surgical method. Based on the characteristics of the site, it involves multiple organs such as the pancreas, duodenum, and bile ducts. The anatomical structure of the organism is destroyed, and the destroyed structure is artificially constructed to create a highly difficult surgical technique for new physiological channels. With the development of medicine, the application of three-dimensional visualization technology in this operation can accurately measure the pathology of the duodenum and its surrounding organs, and make preoperative planning and planning for the excision of the duodenum and its surrounding organs. The success of the operation plays an important role. This article mainly analyzes the current situation of the anatomy of the duodenum and its surrounding organs under the background of current medical technology, and proposes an idea on how to optimize and enhance the anatomy of the duodenum and its surrounding organs. Series recommendations. And try to find a new way out for the anatomy of the duodenum and its surrounding organs in the current era based on the results of these studies. Experimental research shows that the use of three-dimensional technology can greatly improve the anatomy of the duodenum and its surrounding organs. The use of this technology, combined with the doctor's solid foundation, can greatly improve the success rate of the operation.

Abstract Background Peroral cholangioscopy (POCS) can be useful for difficult bile duct stone clearance. Large prospective multinational data on POCS-guided lithotripsy for clearing difficult bile duct stones in a single session of endoscopic retrograde cholangiopancreatography (ERCP) are missing. Methods Patients with difficult bile duct stones (defined as one or more of: largest stone diameter ≥ 15 mm, failed prior attempt at stone clearance, impacted, multiple, hepatic duct location, or located above a stricture) were enrolled at 17 centers in 10 countries. The principal endpoint was stone clearance in a single ERCP procedure using POCS. Results 156 patients underwent 174 sessions of POCS-guided electrohydraulic or laser lithotripsy. Stone clearance had failed in a previous ERCP using traditional techniques in 124/156 patients (80 %), while 32 /156 patients (21 %) were referred directly to POCS-guided therapy based on preprocedural assessment of the difficulty of stone clearance. In 101/156 patients (65 %), there were impacted stones. POCS-guided stone clearance was achieved in a single POCS procedure in 125 /156 patients (80 %, 95 % confidence interval [CI] 73 % – 86 %), and was significantly more likely for stones ≤ 30 mm compared with > 30 mm (odds ratio 7.9, 95 %CI 2.4 – 26.2; P = 0.002). Serious adverse events occurred in 3/156 patients (1.9 %, 95 %CI 0.4 % – 5.5 %), and included pancreatitis, perforation due to laser lithotripsy, and cholangitis (n = 1 each), all resolved within 1 week. Conclusion POCS-guided lithotripsy is highly effective for clearance of difficult bile duct stones in a single procedure and successfully salvages most prior treatment failures. It may also be considered first-line therapy for patients with difficult choledocholithiasis to avoid serial procedures.

Combining classical educational methods with interactive three-dimensional (3D) visualization technology has great power to support and provide students with a unique opportunity to use them in the study process, training, and/or simulation of different medical procedures in terms of a Human Anatomy course. In 2016, Rīga Stradiņš University (RSU) offered students the 3D Virtual Dissection Table “Anatomage” with possibilities of virtual dissection and digital images at the Department of Morphology. The first 3D models were printed in 2018 and a new printing course was integrated into the Human Anatomy curriculum. This study was focused on the interaction of students with digital images, 3D models, and their combinations. The incorporation and use of digital technologies offered students great tools for their creativity, increased the level of knowledge and skills, and gave them a possibility to study human body structures and to develop relationships between basic and clinical studies.

Objective: The current study aimed to examine the anatomical structure of the hepatic vein of segment IV liver (S4) of the liver using three-dimensional (3D) visualization technology in order to explore the surgical value of the middle hepatic vein (MHV) manipulation and highlight the importance of current research in hepatic surgery.Methods: Between January 2014 and December 2019, 52 patients with abdominal diseases(not including hepatic disease) were selected for multiphasic computed tomography-enhanced scans of the upper abdomen. A 3D visualization system was utilized to display the structural details of the hepatic veins in S4 of their livers. Couinaud's eight-segment classification system was used to denote the liver' sections.Results: The constructed 3D model clearly displayed vascular morphological characteristics and their location in the liver, hepatic artery and vein system, and portal vein system. Of the 52 patients, 43 had an umbilical fissure vein (UFV) (82.7%), 19 had an accessory S4 liver vein (36.5%), 16 had both a UFV (30.8%) and an accessory S4 liver vein, and 6 had neither (11.5%). A total of 79% of the patients with a UFV and 74.2% of those with an accessory S4 liver vein had venous blood returning into the left hepatic vein.Conclusion: 3D visualization technology was used to determine hepatic venous return of S4 hepatic veins and was found to improve the safety of evaluation in hepatic surgery.
