Filter by:In patients who underwent sphincter preserving surgery with toal mesorectal excision and diverting stoma after neoadjuvant chemoradiation therapy for rectal cancer, the inestigators would evaluate the effect of a biofeedback therpy before stoma closure on their anorectal function after stoma closure.
The purpose of this research study is to evaluate if a negative-pressure dressing placed over a surgical incision can reduce the risk of developing a surgical site infection compared to a commonly-used sterile gauze incision dressing. In this study, the negative-pressure dressing will be compared to a standard post-surgical sterile gauze dressing. In this study patients will either receive a negative-pressure dressing or a standard sterile gauze dressing
The purpose of this study is to evaluate the efficacy, toxicity and feasibility of FOLFOX/ bevacizumab and FOLFOXIRI/ bevacizumab neoadjuvant therapy in poor prognosis rectal cancer as defined by MRI.
At the end of the neoadjuvant radiochemotherapy, patients are seen by their surgeon to planify the surgery. During this visit, the study will be explained them and their consent obtained. They will then be randomized between the two groups 7 weeks vs. 11 weeks. Patients were reviewed 15 days before surgery and at 1 and 3 months after surgery. Participation in this study does not change treatment, investigations and consultations usually necessary for management of rectal cancer. The objective is to improve the pathological complete response rate of the rectal cancer.
The present prospective randomized study investigated the results of ELRR (ENDOLUMINAL LOCO-REGIONAL RESECTION BY TRANSANAL ENDOSCOPIC MICROSURGERY) versus LTME (LAPAROSCOPIC TOTAL MESORECTAL EXCISION) in the management of 100 patients with iT2N0M0 small low rectal cancer after Neoadjuvant Treatment.
The clinical benefit of resection of the primary tumour in patients with synchronous unresectable metastases is not known. In the literature studies usually describe retrospective selected patients with synchronous metastases treated with or without resection of the primary tumour. All these studies are biased in patient selection and there are no prospective randomized studies on this topic. In patients with few or absent symptoms of the primary tumour, arguments both in favour and against initial resection have been presented, and therefore a randomized trial is warranted. Although recent publications suggest that resection of the primary tumour in synchronous metastasized colon cancer patients might not be necessary, this appears to be based on feasibility and not on clinical outcome. Several studies comparing large groups of patients with or without resection of the primary tumour suggest an improved survival when the primary tumour is resected. A potential benefit of resection of the primary tumour is to prevent complications of the primary tumour during chemotherapy treatment or during later stages of the disease. A recent analysis of the CAIRO and CAIRO2 data showed that metastatic colon cancer patients who had a resection of the primary tumour prior to study entry, had an improved survival compared to patients without a resection of the primary tumour. However, these patients were selected after the primary tumour was resected and therefore these results are not corrected for surgical morbidity and mortality. The investigators here propose a randomized trial in order to demonstrate that resection of the primary tumour does improve overall survival.
Low anterior resection syndrome (LARS) is frequent after treatment for low rectal cancer. Increased bowel frequency and urgency with rectal spasms and incontinence have deleterious impacts on quality of life in a third of the cases. One possible physiopathology hypothesis suggests an ongoing spastic process; different mechanisms have been postulated. These include alteration of normal anorectal sensation with loss of the recto-anal inhibitory reflex (RAIR), decreased rectal compliance and reduced rectal capacity as well as sphincter damage secondary to preoperative chemoradiation therapy or during surgery. Current available treatments are often ineffective, highlighting the need for more successful management. Botulinum toxin A (BTX-A) is a neurotoxin inhibiting acetylcholine release at the neuromuscular junction. It is currently used for the treatment of various smooth muscle spastic diseases. The hypothesis of this study is that intra-rectal BTX-A injections could represent a medical treatment alternative for LARS. The goal of this study is to document the effects of intra-rectal BTX-A injections on sphincter function and quality of life of patients with LARS.
One of the major problems of rectal cancer surgery is pelvic autonomic nerve damage, which is the main cause of urogenital dysfunction influencing postoperative quality of life. Costs for diagnostics and treatment of short and long-term urogenital dysfunction are immense. Varying degrees of urogenital dysfunction are found in up to 32% and 55% of patients with rectal cancer despite potentially nerve-sparing total mesorectal excision (TME). The study will examine the impact of a newly developed continuous monitoring device for preservation of urogenital function in patients with TME for rectal cancer. 188 patients will be included in the prospective, randomized, single-blind, parallel group multi-centre trial including two arms (TME with and without intraoperative continuous monitoring of pelvic autonomic nerves). The primary efficacy endpoint is the change in urinary function measured by International Prostate Function Score (IPSS) 12 months after surgery. Genital functions measured as secondary endpoints. The application of the continuous intraoperative neuromonitoring device could enhance the objective intraoperative confirmation of pelvic nerve sparing surgery. The investigators hypothesis is that the use of his device minimizes the risk of postoperative urogenital dysfunction in patients with TME for rectal cancer. An enormous reduction of treatment costs is to be expected.
Background: Single-port laparoscopic surgery is emerging as a method to improve morbidity and cosmetic benefits of conventional laparoscopic surgery and minimize the surgical trauma. However, the feasibility of this procedure in rectal surgery has not been determined yet. The aim of this study is to evaluate our initial experience using single port access in laparoscopic rectal surgery. Design: randomized, prospective clinical study Patients: 40 patients
