Filter by:After the Introduction of the pathological circumferential resection margin (CRM status by LEEPP Protocol), residual cancer (R1 resection) was most often found in the dorsal and medial resection margins. Yet only the medial resection margin is preoperatively evaluated during staging, while the dorsal resection margin which embeds the mesopancreatic fat and thus resembles the area of the mesopancreas, is not considered during preoperative assessment for resectability. Local recurrence is similarly prevalent as systemic relapse, and revised lower rates of R0CRM- resections through the LEEPP protocol explained the poor local tumor control. The aim of this study is to interdisciplinary approach the circumferential infiltration status of the PDAC concentrating foremost on the mesopancreas of the dorsal resection margin by including anatomic and embryologic derived perspectives.
To understand the current situation of the postoperative gastrointestinal dysfunction in patients with colorectal cancer effect a radical cure, and analyze the risk factors, and build the colorectal cancer radical surgery in patients with gastrointestinal dysfunction risk prediction nomogram model decision tree classification and regression tree model, through internal validation evaluation the performance of the two models in the modeling data set and dividing the postoperative gastrointestinal dysfunction risk level.Two risk prediction models were used to carry out external verification, evaluate the clinical practicability and effectiveness of the model, and provide reference for further promotion of the model.
The investigators designed a protocol for a Bayesian unplanned posthoc analysis using the pooled dataset from three large randomized clinical trials. The primary endpoint will be a composite of postoperative pulmonary complications (PPC) within the first seven postoperative days, which reflects the primary endpoint of the original studies. The investigators will carry out a reanalysis of the harmonised database using Bayesian statistics.
The shoulder is the most mobile joint in the human body. Movements are carried out in most of the activities we participate in, such as work, sports, household tasks, shopping and leisure activities. Shoulder diseases affect 21% of the western population and is one of the most frequent reasons for consultation in orthopedics and rehabilitation consultations. Shoulder pain is in a large majority of cases related to the slope of the acromion and rotator cuff pathology, which would include the slope of the acromion syndrome. The degree of involvement can range from bursitis, tendinitis, to tendinous ruptures. Initial treatment is usually conservative and may consist of anti-inflammatory medication and rehabilitation. When the pain is not relieved, surgery is usually recommended. Surgery for rotator cuff tears is increasingly performed minimally invasive, using arthroscopy. Hospital admission days are currently being reduced, so many of the scheduled shoulder surgeries are performed via the Outpatient Surgery Unit. Often, users are not seen again by the surgeon until a week after the intervention. The affected person must empower themselves and participate actively and progressively in their recovery process. This process begins right after the surgical intervention. Therefore, it is very important that the person has all the necessary information about the surgical procedure that has been performed. Patient education is crucial to reduce anxiety and optimize surgical outcomes.
Study Design - A Counterbalanced Study Aims - To determine the effect of a) warm-up exercises and b) mental visualisation on the musculoskeletal demands and cognitive demands respectively during robot-assisted laparoscopic surgery. Outcome Measures - 1. EMG measurements of frequency and amplitude across muscle fibres. 2. EEG measurements of peak alpha power, and alpha spindle duration and amplitude. Study Participants and Eligibility - Surgeons who have certificates of completion of training (CCT) and performing surgical procedures using the minimally invasive techniques of RALS. Planned Size of Sample - The investigators have chosen the higher value for our power calculation (an effect size of 0.24) which requires 10 surgeons per condition performing 1 -2 operations for 80% power to detect a difference between conditions, at an alpha of 0.05. Planned Study Period-Duration - Each surgeon will be required to participate in the study for approximately 3 - 4 weeks performing 3 surgical procedures and based on estimates that surgeons routinely perform an average of 1 robotic procedure per week we anticipate the study will run for 6 months. Research Question - Does structured simulated warm-up exercises prior to performing surgery improve surgeons' ergonomic awareness and maintain the low muscle fatigue impact associated with RALS? The investigators also hypothesize that mental imagery, inducing a flow state associated with overall cortical synchronisation could decrease cognitive demands experienced by surgeons and potentially mitigate against the cognitive fatigue surgeons experience whilst performing procedures.
Intercostal cryoanalgesia is a technique that allows extensive and prolonged analgesia of the hemithorax. The aim of this study is to demonstrate the efficacy of intercostal cryoanalgesia as an adjunct to a single-injection paravertebral block for the prevention of chronic thoracic pain after VATS lung resection surgery.
The aim of the study is to examine the effects of distraction methods such as watching cartoons and ball squeezing on the level of pain and physiological parameters in the postoperative period in children aged 6-12 years who have outpatient surgery. The research is a randomized controlled trial. The sample number was determined as 40 children (total 120) in each group. Information Form, Physiological Parameters Follow-up Form, Wong-Baker Faces Pain Scale will be used to collect research data. In the initiative group, two attempts will be implemented, namely watching cartoons and squeezing the ball. Interventions will be implemented for a total of 15 minutes. Physiological Parameters Follow-up Form and Wong-Baker Faces Pain Scale will be filled in before the interventions are applied, 10 minutes during the intervention and 5 minutes after the intervention is completed. In the control group, the 10th and 20th minute physiological parameters and the Wong-Baker Faces Pain Scale will be evaluated after the child comes to the service after the operation and is prepared for the postoperative period (taking vital signs, putting on clothes, controlling bleeding, telling the feeding time, etc.). In the analysis of study data; chi-square test for descriptive statistics, chi-square test for repeated measurements, single factor analysis of variance, Mann-Whitney U test and Friedman will be used. In the study, values at the p<0.05 level were considered statistically significant.
Patients' outcome was studied after surgery for renal cell carcinoma. The primary outcome was overall survival and desease free survival. Secondary outcame was complications to surgery.
Background: Bone-patellar tendon-bone (BPTB) and a double-looped semitendinosus gracilis (hamstring group) graft are commonly used for ACL reconstruction. Short-term and mid-term studies show little to no significant difference between the two groups, and there are a few long term studies to compare results between the two grafts. Purpose: To compare the results after using either BPTB grafts or hamstring grafts 18 years after ACL reconstruction. Study design: Randomized controlled trial; Level of evidence II. Methods: 114 patients with ACL rupture between 2001 and 2004 were randomized to reconstruction with either BPTB graft or a hamstring graft. Patients were operated at four major hospitals. The 18-year follow-up evaluation included isokinetic testing of muscle strength, patient-reported outcome measures, clinical knee examination and an assessment of radiological osteoarthritis using the Kellgren-Lawrence classification. Hypothesis:Hypothesis is that there will be no difference in the long-term outcome between the two groups, as well hypothesis of no difference in patients with prosthesis after ACL reconstruction, arthrosis difference in operated knees and the rate of graft failure between the two groups. Previous follow-up studies showed a significant difference in total flexion work between the two groups, so detecting a persistent difference between the groups will be point of interest.
This study aims to find out the role of plasma I-FABP level, SOFA score, fluid balance, and vasopressor dose in predicting gastrointestinal dysfunction in high-risk postoperative patients treated in ICU
