NCT ID: NCT03658083 Recruiting - Lung Cancer Clinical Trials

Exploring Robotic-assisted Thoracic Surgery for Lung Cancer

Start date: October 12, 2017
Study type: Observational

Background Surgery for lung cancer can be performed using open (thoracotomy) or minimally invasive techniques (Video Assisted Thoracic Surgery (VATS)). Despite being associated with fewer postoperative complications (PPCs) VATS is difficult to perform and is only used by 20-44% of thoracic surgeons in the UK. Robotic-Assisted Thoracic Surgery (RATS) maybe a more attractive minimally invasive approach. To date, no studies have explored the impact of RATS on exercise capacity or physical activity and although 1 study has looked at Heath Related Quality of Life (HRQOL) post-RATS compared to an open technique indicators of surgical technique were not controlled for. Furthermore, investigators have little understanding of patients' experience of RATS. Aims 1. To examine the variability of change in exercise capacity and health-related quality of life (HRQOL) between those who receive thoracotomy V RATS. 2. To compare the difference in post-operative physical activity (step and activity count), across 7 days, in those who receive thoracotomy V RATS. 3. To explore the manner in which patients appraise their experience of undergoing RATS. Methods: A mixed-method, multi-center study will be undertaken, utilizing a prospective quasi-experimental study design and an interpretive phenomenological approach. 80 individuals, referred for a lung lobectomy with a primary or secondary diagnosis of lung cancer, will complete outcomes assessed at 4 time-points. The Incremental Shuttle Walk Test (ISWT) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C30) and the EORTC Lung Cancer module (EORTC QLQ LC13) will be completed at: baseline, 3-6 days post surgery, 6-weeks post-surgery and at 3-month follow up. Patients will wear an activity monitor immediately post-surgery until 1-week post-discharge. Step and activity counts will be recorded. In-depth interviews will be conducted with up to 15 patients who underwent RATS to explore the manner in which patients appraise their experience of RATS.

NCT ID: NCT03651973 Not yet recruiting - Breast Cancer Clinical Trials

Prevention of Sequelae Pain After Breast Cancer Surgery by Self-massages and Self Stretching. Impact of Learning Workshops.

Start date: September 15, 2018
Phase: N/A
Study type: Interventional

Myofascial pain syndrome is a common cause of chronic pain characterized by myofascial pain and trigger points. Recommendations regarding management of pain after breast cancer don't mention myofascial syndrome despite a study suggests possible myofascial syndrome with roughly 75% of patients in pain. 144 patients having a local breast cancer requiring surgery will be randomized in this study, ratio 1:1 standard and experimental groups. Every patients (standard and experimental groups) will attend 4 specific consultations during which standard recommendations will be given, pain, quality of life, shoulder range of motion, global upper limbs force will be assessed. In addition, patient randomized in experimental group will attend self massages and self stretching workshops, one before surgery and one after surgery. Patients will be encouraged to performed daily self massages and self stretching. The aim of the study is to assess impact of self massages and self stretching workshops on sequelae pain further surgery for breast cancer.

NCT ID: NCT03646734 Completed - Surgery Clinical Trials

Guided Bone Regeneration With Particulate Versus Block Graft

Start date: January 10, 2017
Study type: Observational

The aim of present study was to compare two bone augmentation techniques (Guided Bone Regeneration, GBR, with autogenous block graft and GBR with particulate autograft plus xenograft) in terms of efficacy, complications, operational parameters (cost of the materials used, time for patient preparation, time for surgery, fatigue of the physician caused by surgery) tolerability by the patient and patient comfort.

NCT ID: NCT03645252 Not yet recruiting - Lung Cancer Clinical Trials

Sequence of Vessel Interruption and Circulating Tumor Cells in Surgical Lung Cancer

Start date: August 31, 2018
Phase: N/A
Study type: Interventional

This study aims to define the impact of the sequence of vessel interruption on change in CTC and CTC clusters density in the tumor-draining pulmonary vein between the period before surgical manipulation and before tumor-draining vein interruption.

NCT ID: NCT03643926 Not yet recruiting - Surgery Clinical Trials

Arthroscopic Versus Open Brostrom for Ankle Instability

Start date: October 1, 2018
Phase: N/A
Study type: Interventional

Background: Ankle sprains are among the most prevalent lesions in primary care. A substantial number of these ligament lesions will develop ankle instability and require a surgical procedure. The Brostrom-Gould technique is the standard surgical approach for this condition, providing excellent results over the years. Thru the last decades, the arthroscopic Brostrom has gain popularity and support by several studies. Yet, there is no consensus regarding the best procedure to treat ankle instability nowadays. Hypothesis: The arthroscopic Brostrom technique will present better levels of pain and function when compared to the standard open approach. Design: blinded, in parallel groups, multicentric, randomized, clinical trial. Materials and Methods: 98 patients with a diagnosis of chronic ankle instability, referred from primary or secondary health care services, will be assessed and enrolled in this study. Participants will be divided in two groups (randomized by sequentially numbered identical envelopes, which will be administered serially to participants), one containing the open Brostrom repair technique and the other comprehending the arthroscopic Brostrom approach. The assessments will occur in 3, 6, 12, 24 and 48 weeks. Patients will be evaluated primarily by complications and secondarily the Cumberland Ankle Instability Tool (CAIT), American Orthopedic Foot and Ankle Society (AOFAS), the Visual Analogue Scale (VAS), the Foot Function Index (FFI) and the 36 Item Short Form Health Survey (SF-36). The investigators will use Comparison of Two Proportions via relative frequency analysis, the Pearson Correlation the Chi-Square test and the ANOVA for statistical analyses. Discussion: This study intends to establish if the arthroscopic Brostrom technique can produce excellent and reliable results when treating chronic ankle instability. A shorter surgical time, a better cosmetic appearance and a smaller soft tissue injury would support the choice for this procedure if the outcomes could be compared to the open approach.

NCT ID: NCT03638492 Completed - Melanoma Clinical Trials

Trial of Surgical Excision Margins in Thick Primary Melanoma - 2

Start date: January 1992
Phase: N/A
Study type: Interventional

Objectives: The purpose of this study was to assess the long-term follow-up of the overall and melanoma-specific survival in the randomised, open-lable multicenter trial (NTC NCT01183936) comparing excision margin of 2 cm versus 4 cm for patients with primary cutaneous malignant melanoma (CMM) thicker than 2 mm. Study hypothesis: The hypothesis is that there is no difference between the two treatment arms measured as melanoma-specific survival and overall survival.

NCT ID: NCT03636568 Recruiting - Surgery Clinical Trials

Hyponatremia Study (Delayed Hyponatremia After Pituitary Surgery)

Start date: June 2, 2016
Phase: N/A
Study type: Interventional

Hyponatremia is defined as sodium below the normal range of 135-145. Symptomatically, it can cause patients to experience a wide range of symptoms including lethargy, headache, nausea, vomiting and in severe cases coma and even death. The goal of this study is to prospectively compare two approaches to the postoperative fluid management of patients undergoing transsphenoidal resection of a pituitary tumor or cyst to decrease the occurrence of postoperative delayed hyponatremia. One group will be placed on moderate fluid restriction and the other group will be placed on ad lib fluid intake.

NCT ID: NCT03627325 Completed - Surgery Clinical Trials

The Difference in Preoperative Evaluation That is Given by a Senior Physician, a Specialist, and a Computer Program

Start date: October 2, 2014
Study type: Observational

There is an increasing need and interest in being able to empirically estimate customized, patient-specific risks for virtually all surgical operations in a user-friendly format. The ACS (American College of Surgeons) surgical risk calculator is a decision-support tool based on reliable multi institutional clinical data, which can be used to estimate the risks of most operations.1 The aim of this study is to compare the assessment provided by the The ACS Surgical Risk Calculator with the assessment provided by a senior and a resident anesthesiologist, and by that comparison to establish the need for the ACS calculator
