Filter by:This study aims to establish a colorectal cancer cohort, collect clinicopathological information, collect biological samples for multi-omics testing, and perform relevant analysis, to predict the prognosis of colorectal cancer, guide the diagnosis and treatment of colorectal cancer and the formulation of health policies.
Sudden hypotension, which may develop during liver resection operations performed under general anesthesia, can affect the patient satisfaction at a high rate by causing complications during and after the operation as a result of disrupting the blood supply of the tissues. Although there are standard monitoring methods such as blood pressure, heart rate, and oxygen status that show unwanted hypotension during anesthesia, it is possible to show hypotension in the early period with new generation methods. Although there are many clinical studies proving the effectiveness of these methods, these methods have not yet been included in the standard monitoring methods. Our prediction in this study is that the development of intraoperative and postoperative complications in patients who will undergo liver surgery, in whom tissue blood flow is monitored with the help of devices, will be less than in patients who are followed up with traditional methods. If an individual participate in this study, he will not be subjected to any additional procedures other than routine practice during the participant's operation. Before standard general anesthesia for his surgery, heart rate, oxygenation status, blood pressure parameters will be monitored. After the initiation of general anesthesia, the procedures performed in each liver surgery will be applied. In addition, he will be followed by using a probe that allows monitoring of tissue blood flow and reflects a value to the screen, to which it is attached, by simply sticking to his skin.
With the digital age, guided surgery and cases of fully computer-assisted surgeries via 3D printing guides and preformed plates are booming. Our project aims to study the performance and safety of personalized implants (personalized guides and plates) in orthognathic surgery in order to obtain specific clinical data on SLS France devices.
A patient with a tumor lesion of the chest wall undergoes CT scan with a step width of less than 1 mm, then engineers design an individual model to replace the defect. Using a 3D printer, a model is made based on titanium alloy powder. Preoperative preparation takes an average of 14-21 days. The next stage is surgical treatment in the amount of resection of the chest wall with plastic defect with an individual titanium implant. In some cases, the titanium framework is separated from the pleural cavity by a polytetrafluoroethylene plate in order to seal and prevent the development of pulmonary hernias. The advantages of titanium individual prostheses include accurate matching of the implant to the size and characteristics of the defect, individual modeling allows you to repeat the anatomical features of the patient. This method helps to recreate the original shape of the chest, and most importantly, symmetrical, relatively healthy half. With the help of titanium, individualized prostheses are made based on 3D modeling, which will reduce the incidence of complications, accelerate rehabilitation and improve the quality of life of patients with tumor lesions of the chest wall. The postoperative period takes 15-30 days.
To evaluate the short-term outcomes of single-incision plus one-port laparoscopic surgery (SILS + 1) versus conventional laparoscopic surgery(CLS) for distal gastric cancer whose clinical stage was cT1-3N0-2M0
Real-world studies on long-term prognosis in patients who underwent anti-tumor treatments during hospitalization from a hospital-based cancer registry in china.
The objective of the present study is to compare the effectiveness of dry-lab laparoscopic training and robotic simulator training among medical students without any prior laparoscopic experience.
An observational study to collect data from the participants who received urologic surgeries using the Senhance Robotic system.
Conventional monopolar or bipolar transurethral resection of bladder tumors is the most common method for resection of a bladder mass. En bloc resection has demonstrated success in the literature utilizing different techniques and lasers, including utilizing the Ho:YAG and Tm:YAG lasers. A recent metanalysis revealed several benefits to laser en bloc resection including less complications and lower recurrence rate.22 Subsequently, laser technology has also advanced with the development of a super pulsed TFL which overcomes many limitations of prior traditional lasers. Olympus' SOLTIVE™ TFL, which has demonstrated improved maneuverability and control, has a shallow depth of tissue penetration at 0.15mm leading to precise resection and optimal hemostasis. Despite these beneficial characteristics and qualities along with the promising utility of en bloc resection, the Olympus SOLTIVE™ TFL has not been described in en bloc resection of bladder tumors. The investigator seek to determine if the proposed benefits of this device can be realized both pathologically and clinically in en bloc resection of bladder tumors.
Magnetic devices have been successfully used in bariatric surgery. To the date the only reported use of the magnet was for liver retraction. This study is to demonstrate the safety and viability of using the magnetic system as a second surgical assistant in bariatric surgery and not only for liver retraction.
