Filter by:The aim of this study is evaluate the effect of two different surgical treatment on lower rectal cancer after almost clinical complete response(almost-cCR). All almost clinical complete response(almost-cCRs) were entered into two groups randomly. The estimated sample size of the minimal operation group was 221, and 221 in the Mile's group. Three years' progression-free survival(PFS) and overall survival(OS) were compared.
Aim of the MANCO study is to establish for once and for all that monitoring the effect of heparin during NCVI (Non-Cardiac Vascular Interventions) is essential to ensure the individual patient of safe and tailor-made anticoagulation. Not measuring the effect of the administered heparin exposes the patient to unnecessary risks of thrombo-embolic and bleeding complications. First aim of the MANCO study is to prove that the standardized bolus of 5000 IU of heparin, used by 90% of vascular specialists in Europe, results in inadequate anticoagulation in more than 80% of patients. These measurements will be performed using the Hemostasis Management System by Medtronic.
Three-dimensional (3D) printing has gained popularity in medicine over the last decade. Once 3D printers have become more affordable, the true strength of this technique has been recognized because of its ability to obtain anatomical models based on the unique characteristics of each patient. Liver resections are challenging operations because of the complex nature of the liver and venous anatomy within the liver, so 3D imaging is a promising new tool for surgical planning.
This study is a multi-center phase 3 trial to evaluate a treatment strategy for selecting patients who can benefit from the synchronous resection of primary pancreatic cancer and liver oligometastasis after induction chemotherapy. Half of participants who meet the entry criterion will receive surgical intervention, while the other half will continue to receive standard chemotherapy.
An open label observational registry trial in which participating centers enroll subjects who had or will have a laparoscopically assisted surgery using the Senhance Surgical System.
Cholangiocarcinoma (CCA) is the most common biliary tract malignancy and the second most common primary hepatic malignancy. The prognosis of CCA is dismal. Surgery is the only potentially curative treatment, but the majority of patients present with advanced stage disease, and recurrence after resection is common. It is classified into intrahepatic (iCCA), perihilar (pCCA), and distal (dCCA) subtypes. Among all, pCCA is the most common subtype. This is a prospective, randomized, controlled multicenter trial with two treatment arms, three dimension laparoscopic approach versus open approach. The trial hypothesis is that three dimension laparoscopic surgery has advantages in postoperative recoveries and be equivalent in operation time, oncological results and long-term follow-up compared with open counterpart. The duration of the entire trial is two years including prearrangement, follow-up and analyses.
Esophageal cancer is one of the most common cancers worldwide, while more than half new cases and deaths occurred in China. Surgery is the main curative treatment for this disease, the 5-year survival of EC remains poor, since most diseases are diagnosed at advanced stages. In last decades, several large clinical trials and meta-analyses have demonstrated that neo-adjuvant chemoradiotherapy followed by surgery can significantly increase the overall survival of patients with EC compared with surgery alone, while no effect of nCRT was apparent on postoperative health-related quality of life . However, the optimal radiation dose and surgery timing are still unknown. The investigators hypothesize that patients who receive higher dose (50.4Gy/28F) of neoadjuvant chemoradiation will have better pathologic response and progress-free survival compared to lower dose (41.4Gy/23F) of chemoradiation followed by surgery.
In this prospective, multicentre, open, randomised, controlled clinical trial elderly patients (≥ 70 years) undergoing intermediate- or high-risk non-cardiac surgery will be randomised either to a liberal group (patients receive a RBC unit each time Hb falls ≤ 9 g/dl (≤ 5.6mmol/l) with a target range for the post-transfusion Hb level of 9-10.5 g/dl (5.6-6.5 mmol/l)) or restrictive group (patients receive a single RBC unit each time Hb falls ≤ 7.5 g/dl (≤ 4.7 mmol/l) with a target range for the post-transfusion Hb level of 7.5-9 g/dl (4.7-5.6 mmol/l). Primary efficacy endpoint: is a composite of death from any cause and anaemia-associated, ischaemic events (defined as acute myocardial infarction, acute ischaemic stroke, acute kidney injury stage III, acute mesenteric ischaemia, acute peripheral vascular ischaemia) within 90 days after surgery.
The role of nutritional therapy (TN) in the surgical patient is well described in the literature and is associated with reductions in postoperative complications, length of hospital stay, and mortality. Adequate determination of caloric and protein requirements is an essential step in the TN institution, avoiding hypoalimentation and hyperalimentation. Thus, it is essential to understand the changes in energy expenditure after surgery and its relation with nutritional status. In addition, little is known about the effect of nutritional therapy and caloric adequacy on parameters such as phase angle and dynamometry. Thus, the objective of this study is to evaluate the changes in energy expenditure after major abdominal surgeries and to evaluate the phase angle and dynamometry as possible markers of nutritional therapy. Energy expenditure will be assessed by indirect calorimetry. Functionality will be assessed by means of dynamometry and 6-minute walk test. Nutritional diagnosis will be given through subjective global assessment. Energy and protein intake will be monitored and registered daily. Phase angle will be obtained by performing bioelectrical impedance.
Investigators conducted a pilot study to to evaluate the autonomic function in participants with pectus excavatum before and after Nuss surgery.
