Filter by:The investigators designed a new preoperative chemoradiotherapy regimen to focus on the most important radiation area and hope to reduce the radiation volume and try to reduce the postoperative mortality and treatment-related mortality.
The purpose of this study is to determine the effects of two different internal limiting membrane peeling with distinct diameters after macular hole surgery on anatomical closure grades.
The aim of this study is to explore whether the use of ultrasound guided phrenic nerve block can reduce the postoperative pain in the shoulder after liver resection. The intervention is directed postoperative to the patients experiencing novel right sided shoulder pain.
The purpose is to calculate the time for an optimal recovery (T4/T1 > 0.9) from the moment when 2 responses to double burst stimulation are visually identical and this for 95% of patients.
The purpose of this study is to determine whether a local fractionated radiation therapy achieves a better local tumor control after complete surgical metastases resection at 6 month as compared to observation alone. Further it should be evaluated if cognitive functioning and quality of life is similar in both groups.
This will be a multicentre, randomised, controlled and prospective clinical trial. All participants provided their written informed consent to participate in a randomized trial that examined the effects of low-level MAP (60-70 mmHg) vs. high-level MAP (90-100 mmHg) in elderly patients (65 or more years of age) during noncardiothoracic surgery under general anesthesia. The investigators hypothesise high-level blood presure of the intervention for reducing the incidence of post-operative complications.
Usually, cervical spine fractures are not considered as osteoporotic fractures. However, recent studies show that odontoid fractures are the most common fractures of the cervical spine in elderly and may occur in a context of low trauma energy. Thus, the goal of this observationnal study is : - to describe the different type of odontoid fracture and to characterize bone status in elderly patient (>65 y) who underwent odontoid fracture in a context of low trauma energy. - To describe short and long term outcomes
This prospective randomized study aims to determine the influence of the use of local hemostatic on the incidence of local complications derived from the edge of transection: biliary fistula or bleeding, after scheduled hepatic resection.
Compared with traditional open proctectomy, laparoscopic surgery is associated with less pain, earlier recovery, and better cosmetic outcome, and its long-term oncologic outcomes have been demonstrated. However, the rate of urinary dysfunction after rectal cancer surgery was about 19-38% because of mesorectal excision. The type of drainage is unclear. Some studies show that the rates of urinary tract infection, second catheterization, and urinary symptom are lower with suprapubic catheterization (SPC) than with transurethral catheterization (TUC). Moreover，SPC allows for testing the bladder voiding without drainage removal. Furthermore，SPC using central venous catheter(CVC) is less invasive. Currently, there is lack of randomized controlled trial(RCT) to compare SPC with TUC. Therefore, investigators perform this prospective randomized trial to compare SPC using CVC with TUC in laparoscopic surgery for rectal cancer.
The purpose of this study is to evaluate whether the long-term outcome and safety of wedge resection are comparable to segmentectomy for the surgical treatment of early stage (IA) non-small cell lung cancer (NSCLC). Zhang et al. performed a meta-analysis of 53 studies and suggested that sublobectomy achieved a survival rate comparable to lobectomy in a selected population of patients with Stage I NSCLC. However, one critical question needs to be addressed, that is, does sublobectomy require segmentectomy or wedge resection? Cho et al. reported that, for pulmonary ground glass opacity (GGO) nodules (Stage IA NSCLC), wedge resection achieved a 5-year survival rate of 98.6% in the pure GGO group and 95.5% in the mixed GGO group. Cho et al. cautioned against performing wedge resection for mixed GGO nodules with GGO component ≤ 75%, due to the high recurrence rate. When radiology shows that the GGO component is ≥75%, pathology usually finds that the lesions are non-invasive. Therefore, these lesions are potential candidates for wedge resection. This randomized clinical trial is to assess whether wedge resection can be established as a standard treatment for Stage IA NSCLC with tumor size ≤ 2 cm and GGO component ≥ 75%.
