Study on the strategy of three-dimensional anatomy of the duodenum and its surrounding organs

: 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 are 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.


Introduction
Resection surgery is currently recognized worldwide as the most effective treatment for many malignant diseases. Through the regular resection of the diseased organ, the diseased organ can be completely removed without affecting the basic body functions of the person. However, with the irregular resection, more functional tissues are lost. Patients with weak physical fitness especially face a greater risk of postoperative organ failure [1]. In medical treatment, through traditional CT, MRI and other imaging technologies, doctors combined with rich clinical experience can also predict the shape and size of the lesion to a certain extent, but because of the limitations of this technology, there are still Variations of some blood vessels and bile ducts which cannot be detected in advance, and there will still be many emergencies during the operation [2]. Some doctors do not have enough experience to fully grasp the spatial relationship between the pathogen and the surrounding blood vessels and related structures. Therefore, the formulation of the surgical plan will also be unreasonable. The blindness and risk of the operation also exist, and there are some deviations in the precise resection. In the course of the operation, other injuries are caused to the patient, and complications may occur in serious cases [3].
Three-dimensional visualization technology can greatly improve anatomical resection from a technical level [4]. The volume of the duodenum and its surrounding organs and the ratio of the volume of the duodenum and its surrounding organs can be calculated using this technology before surgery. It can be analyzed from many aspects of organ reserve function. Predict the surgical risk in advance, reduce the surgical risk, evaluate the probability of postoperative risk, and effectively improve the safety of surgery [5]. At the same time, when performing preoperative predictive analysis, patients and their families can intuitively understand the surgical plan and surgical risks, which is beneficial to promote communication between doctors and patients and reduce unnecessary medical disputes [6].
In the current era, medical technology still has many shortcomings. For example, the application technology of imaging technology in medicine is not yet mature, and the pipeline structure in the organ is too small, so problems can only be discovered and solved in time during surgery. In clinical practice, it is often difficult for doctors to obtain ideal images of bile ducts in organs [7][8]. Although 3D visualization technology is a relatively mature technology at present, it still has limitations and shortcomings. Doctors should not blindly rely on this technology in clinical practice, and they need to have certain knowledge and rich clinical experience. Blindly relying on three-dimensional visualization technology and ignoring the doctor himself, this will cause judgment and surgical deviation to a certain extent, which is not conducive to the operation [9]. Only on the basis of obtaining reliable and high-quality CT image data, combining the doctor's solid foundation and rich clinical experience, accurately identifying the problematic organ during the operation, and performing resection, can it be possible to maximize the use of 3D visualization technology clinical value advantage [10].

Preoperative analysis
Preoperative comprehensive analysis and discussion of the patient's medical history, combined with three-dimensional visualization technology to accurately assess the patient's current condition, clarify the function of the duodenum and its surrounding organs, and analyze the duodenum and its surrounding organs before the operation anatomy and variation. There is also an accurate risk assessment of this operation, combined with the three-dimensional visualization model for doctors to study and discuss, and work out the best surgical plan.

Statistical methods
The SPASS19.0 statistical system was used for statistical analysis, the measurement data was using t-test, and the comparison of rates was using the PearsonX2 test. When the expected count is small (theoretical frequency T<5), the Fisher's exact test is used. P<0.05 indicates a significant difference. Statistical significance. If a function g(f) satisfies the following relationship: Then the space formed by the function g(f) is called the square integrable space, that is, g(t)∈(R). From this formula, we can see that g(t) is an energy finite function. If the function y(f)∈(t), its corresponding Fourier transform is, when the condition is met: It is called a basic wavelet function. After the function is translated and stretched, the result is a wavelet sequence: The above probability is： R =1-R 4 The above formula leads to the following ruling： x 0 x 1 5

Tree-D model establishment
Since the beginning of the 21st century, 3D printing (3DP) technology has been applied in the medical field. 3D printing technology is the opposite of traditional material removal processing methods. It is based on a three-dimensional digital model and usually uses a layer-by-layer manufacturing method to combine materials. In recent years, 3DP technology has been widely used, such as personalized surgical planning and guiding medical research. Compared with CT, magnetic resonance imaging (MRI) and other two-dimensional imaging, three-dimensional visualization (3Dv) and 3DP models are more intuitive and accurate in displaying the anatomical and spatial structures of organs, and have made great achievements. Three-dimensional visualization reconstruction is to use software to reconstruct a two-dimensional CT image into a three-dimensional visualization model. In order to better show the relationship between tumors or lesions and blood vessels and adjacent organs, 3D printing models can print complete models of tumors, surrounding organs, and large blood vessels, or only print models of selected organs and large blood vessels. Through the physical model and being able to touch the model, it is helpful for clinicians to closely observe the anatomical relationship of the tumor and make preoperative plans. They have been widely used in liver surgery, plastic surgery and orthopedics. However, the application of 3Dv and 3DP in the diagnosis of complex intestinal obstruction is still at an early stage, with few reports. We report a case of intestinal obstruction caused by internal hernia confirmed by 3D visualization technology. Due to timely diagnosis and timely surgery, the patient has a good prognosis.

Experimental investigation objects
In order to be able to analyze the research of the three-dimensional anatomy program in more depth, this article has conducted investigations from both the patients and the doctors, through the anatomy treatment of the duodenum and surrounding organs of 40 patients in a hospital in the past month Understand the situation; and what doctors think about the use of 3D technology in surgery and the impact on surgery. Conduct research and investigation to understand the research results of the research subjects on the subject of this article. Based on the 3D technology Problems and causes in clinical medicine. Through comprehensive processing and analysis of data.

Experimental design
After 40 patients were admitted to the hospital, a comprehensive examination was performed. All patients had no serious surgical contraindications, related matters that could be performed normally, and no related diseases that could not tolerate surgery. 40 patients were treated in groups. Divide them into experimental and control groups, each with 20 people. The experimental group used three-dimensional technology for surgery, while the control group did not use three-dimensional technology for surgery. When selecting 40 patients for surgery, statistics were made on the patients' operating time, surgical blood loss, and postoperative recovery. The experimental group established a three-dimensional reconstruction model for preoperative planning and intraoperative application, while the control group did not establish a three-dimensional reconstruction model for preoperative planning and intraoperative application. Among the relevant indicators for the investigation of the anatomy of the duodenum and its surrounding organs, the average time spent in the experimental group for an anatomical operation of the duodenum and its surrounding organs was about 164 minutes, and the control The average time of the group was significantly reduced compared to 205min, so the difference was statistically significant (P=0.016). The average intraoperative blood loss during the operation of the experimental group was about 240 mL, which was significantly reduced compared with the 420 mL of the control group. The difference was statistically significant (P=0.011). In terms of postoperative recovery, the average time for the experimental group to return to a normal state was 10 days; compared with the 15 days of the control group, it was also significantly reduced, and the difference was statistically significant (P=0.043). From the comparison between the experimental group and the control group, we can see that the experimental group has established a three-dimensional reconstruction model for preoperative planning and intraoperative application. The operation time, surgical blood loss and postoperative recovery are better than the experimental group, so it can It is concluded that three-dimensional technology has a huge improvement in the success rate of surgery, and can be used on a large scale in clinical surgery to reduce the problems that occur during surgery. The data shown in Figure 1 is a survey of doctors in the hospital. From the data in the figure, it can be seen that the use of three-dimensional technology in the anatomy of the duodenum and its surrounding organs still has a great impact on the operation. It has a certain degree of influence on the mainstream ideology of doctors. 85% of doctors believe that 3D technology has a great impact on the anatomy of the duodenum and its surrounding organs, and 12% of doctors believe that 3D technology is useful for the anatomy of the duodenum and its surrounding organs. 2% of doctors believe that 3D technology has little effect on the anatomy of the duodenum and its surrounding organs, and 1% of doctors believe that 3D technology has little effect on the duodenum and its surrounding organs. The anatomy performed has no effect. According to the results of this investigation, three-dimensional technology has a great impact on the anatomy of the duodenum and its surrounding organs.

Experimental results
With the support of three-dimensional technology, doctors have reduced a lot during the operation. burden. Especially after the continuous development of 3D technology and some breakthrough progress, it gradually began to receive the attention of medical staff.  From the data in Figure 2, it can be seen that the current anatomy of the duodenum and its surrounding organs is basically inseparable from three-dimensional technology. According to the data, 96% of the cases are in the duodenum and its surrounding organs. The three-dimensional technique is often used in the anatomy of the organ. In 3% of the cases, the three-dimensional technique is occasionally used in the anatomy of the duodenum and its surrounding organs, and in 1% of the cases. No need to use 3D technology. Three-dimensional technology is very important and positive for the anatomy of the duodenum and its surrounding organs. The use of this technology in the anatomy of the duodenum and its surrounding organs can greatly improve the success of the operation. rate.
