Filter by:- Aim: The aim of this study is to perform a prospective, international 4 months cohort study evaluating bowel function before curative rectal cancer surgery and one year after the surgery using the LARS score. - Primary outcome measure: LARS score before surgery and 1 year after the surgery. - Primary comparison: Between average LARS score before and after curative surgery and also comparing these with publish LARS score on normal population.
The incidence of prerectal resection syndrome (LARS) after middle and low rectal cancer surgery is as high as 70%, which seriously affects the quality of life of patients. Studies have shown that colon pouch can reduce and alleviate LARS symptoms. However, most previous studies focused on open surgery, and the evaluation index lacked objectivity. Therefore, in the context of minimally invasive rectal cancer surgery, it is necessary to re-evaluate the value of improved surgical methods for the prevention of LARS, so as to improve the quality of life of patients.
Acupuncture has it's role in treating patients with fecal incontinence and diarrhea-predominant irritable bowel syndrome. There is no trial or case-report assessing it's role in treatment of Low anterior resection syndrome.
After undergoing restorative proctectomy for rectal cancer, many patients are left with significant bowel dysfunction, known as Low Anterior Resection Syndrome (LARS). Increased LARS severity correlates with worse perceived global health status and quality of life (QoL). Among patients undergoing rectal resection with a permanent ostomy, there is evidence that supportive and educational interventions improve QoL, ostomy proficiency, self-efficacy and knowledge. However, evidence regarding the impact of such interventions in patients who undergo restorative proctectomy is lacking, despite the latter operation being far more frequently performed. The overall goal of this study is to evaluate the extent to which a LARS Patient-Centered Program impacts on patient-reported outcome measures (PROMs) after restorative proctectomy for rectal cancer. This is a randomized-controlled muticenter trial that will include patients who have undergone restorative proctectomy for neoplastic disease (benign or malignant) located in the rectum (0-15cm from the anal verge) with a diverting ostomy and who are scheduled for ostomy closure.
Low anterior resection syndrome (LARS) is a complex disorder suffered by patients who undergo rectal resection mainly due to rectal cancer. It is characterized by fecal incontinence, fragmented defecation, constipation, defecatory urgency among others, which induce an impairment in quality of life. LARS treatment armamentarium is scarce and with no long-term relief, being a difficult challenge for surgeons. There is evidence showing that sacral neuromodulation (SNM) improves patients' symptoms and quality of life. However, no prospective randomized studies have supported this improvement. This is a prospective randomized cross-over study which evaluates the effectiveness of SNM in LARS, specifically analyzing intestinal, urinary, sexual symptoms as well as quality of life.
Oncological rectal cancer outcomes have improved considerably because of optimal surgery by total mesorectal excision in conjunction with multidisciplinary team management by selective multimodal therapy (ie, neo-adjuvant chemo-radiotherapy). The 5-year survival has increased to more than 50% and local recurrence has been reduced to less than 10%. These advancements have resulted in more patient receiving sphincter-preserving surgery (SPS). With an increasing number of rectal cancer survivors, the investigators observe a rising attention to the disordered bowel function after SPS, called "low anterior resection syndrome" (LARS). LARS appear immediately after surgery, becoming most pronounced during the first few months, and improved thereafter, reaching a steady state after around two years. However, up to 60% of patients with SPS suffer from LARS which impaired their quality of life (QoL). The prevalence and severity of LARS is difficult to assess due to heterogeneity of the assessment tools. A group of Danish authors have recently developed and validated a five-item instruments for evaluation of LARS (LARS score). It represents to date the best questionnaire to capture anorectal postoperative function and consists of five items: incontinence for flatus, incontinence for liquid stool, frequency of bowel movements, clustering of stools, and urgency. It allows a categorization of patients into 3 groups: no LARS (0-20 points), minor LARS (21-29 points), and major LARS (30-42 points). Developed in Danish, it is now internationally validated with translations in Chinese, English, German, Spanish and Swedish. To our knowledge, French version of the LARS score is not yet available. The aim of our study will be to adapt the LARS scale questionnaire to the French language (LARS-F), and assess its psychometric properties. Inclusion criteria will be patients 18 years old or above who were operated for rectal cancer from 2007 to 2015. Exclusion criteria will include the presence of stoma and/or known disseminated or recurrent disease. Patients will be identified through local databases by the local investigators at each of the participating centers with a minimum duration of 24 months after surgery to allow their bowel function to have regained stability. This study will be supported by the French Research Group of Rectal Cancer Surgery in order to allow the feasibility of the project. After translation/back-translation procedures in accordance with the permission from the original authors, the LARS-F score and the whole translation process will be then sent to the original authors for approval. Then a pilot study will be conducted. The French questionnaire (LARS-F score) will be then administered to 100 patients in order to verify the adequacy and degree of comprehension of the questions. Reproducibility will be investigated by a test-retest procedure. A randomly selected subgroup of participants (n= 400) will be sent the LARS-F score questionnaire twice (with an interval of two weeks). The test-retest reliability of the questionnaire will be assessed by the Cohen's Kappa (no, minor and major LARS scores) or by intra-class correlation coefficient, ICC (quantitative LARS score). Then, eligible patients will receive a postal invitation to complete the LARS-F score and the l'European Organization for Research and treatment of Cancer (EORTC) QLQ-C30 and QLQ-CR29, respectively. The validity of the LARS-F score will be tested by using the indicators of convergent validity and discriminant validity. The convergent validity will be determined notably in this study by computing the correlations between the LARS-F score and the EORTC QLQ-C30 and QLQ-CR29 domains. For discriminant validity testing, the investigators will use known variables to affect bowel function after SPS, such as gender, age, neo-adjuvant radiation therapy, distance of the tumor from the anal verge, prior temporary stoma, and length of postoperative period. The validation of the French version of the LARS score will allow to use a scientific instrument in order to assess both prevalence and severity of LARS. This instrument will allow to develop a future research and clinical practice in France. It will be used in the daily clinical practice to identify patients with LARS score. It will hopefully lead to improve the awareness of clinicians, in order to improve the prevention and the treatment of bowel dysfunction, as well as the information given to patients. In the future, the investigators will able to develop a new patient-led follow-up program based on symptom burden and health-related QoL.
Background: Patients treated for rectal cancer are in high risk of developing poor quality of life and faecal incontinence. Faecal incontinence has a negative impact on quality of life. However, there is limited knowledge on how to prevent it. Known exposures are ; age at surgery, gender, tumor height, pre-operative radiotherapy, surgical technique and temporary stoma. In order to evaluate the underlying mechanisms of faecal incontinence, it is central to evaluate the anorectal muscle function for sensory and motor impairment. Exposures representing different constructs in the biopsychosocial model are likewise likely to be associated with quality of life and faecal incontinence. These exposures include sexual dysfunction, urinary incontinence, fatique, physical inactivity and finding meaning in life. There are to our knowledge, no records on these relationships from prior to surgery to 2 years after. These biopsychosocial exposures are central to include when developing strategies that can prevent poor quality of life and faecal incontinence for patients treated for rectal cancer. Purpose: The primary purpose of the EDFI-Cohort study is to determine how several variables (surgical technique, anorectal muscle function, faecal incontinence, urinary incontinence, sexual dysfunction, fatigue, physical activity and finding meaning in life) develop over time and predicts quality of life. Secondary how it predicts LARS-score in patients with rectal cancer from prior to surgery to 2 years after primary treatment. Methods: We will include subjects diagnosed with rectal cancer and have received curative surgery (low anterior resection) with/without adjuvant (radiation/chemo) therapy. The cohort aim to recruit all eligible patients in a one year period. We estimate to recruit 70 patients. Self-reported outcomes will be collected with a series of validated questionnaires that subjects will be asked to complete 6 times during the two year study at 3, 6, 12, 26 78 and 104 weeks. Outcomes include: Quality of life using (EORTC QLQ-C30) (primary outcome), (CR29) and (FA12), bowel related quality of life (LARS-score) (secondary outcome), faecal incontinence (Vaizey score), urinary incontinence (ICIQ-UI), (MLUTS/FLUTS) and (MLUTSsex/FLUTSsex), physical activity level from Danish National Health Profile and finding meaning in life (SOME). Objective measures will be collected at 6 weeks, 6 months, 12 months and 24 months and include: Anorectal manometry that measures anorectal muscle function and rectal perception, a digital examination of anorectal muscle function using the Digital Rectal Examination Scoring System (DRESS) and the six-minute walk test a measure of submaximal exercise capacity. We plan to analyze the EDFI-Cohort study as repeated measures with both simple and multiple linear regression models for the continuous data. We plan to adjust for known confounders and variables related to treatment.
A randomized controlled trial (RCT) in patients who underwent sphincter preserving surgery due to rectal cancer. The study will analyze the effect of Transanal irrigation (TAI) and medication that can help control of the bowel movement in patients with low anterior resection syndrome.
The study aims to evaluate the efficacy of percutaneous tibial nerve stimulation (PTNS) associated with conservative therapy (arm A) for the treatment of low anterior resection syndrome (LARS) compared with only conservative therapy (arm B). The secondary aims are the evaluation of the following parameters: - Effect of PTNS on manometric parameters - Effect of PTNS on quality of life - Effect of PTNS on the severity of fecal incontinence and / or obstructed defecation - Safety of PTNS
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.
