Filter by:The preservation surgery of the anal sphincter muscle has become the standard procedure in the treatment of rectal cancer and, thanks to advancements in surgical techniques, can now be performed for tumors located closer to the anus. This method allows patients to avoid a permanent artificial anus, maintaining continuity of the intestines and enabling bowel movements through the anus, making it a highly preferred procedure. Furthermore, advancements in various tumor treatments have led to improved long-term survival rates. Preservation surgery of the anal sphincter muscle is commonly used in the treatment of rectal cancer, resulting in approximately 90% of patients experiencing changes in bowel habits after surgery. These changes include characteristic diarrhea, urgent bowel movements, frequent bowel movements, and fecal incontinence, collectively known as Anterior Resection Syndrome (ARS). Particularly in the case of low rectal cancer, it often manifests as Low Anterior Resection Syndrome (LARS). These symptoms are most severe immediately after surgery, generally persisting in a significant degree for 1-2 years, with some improvement over time. However, for many patients, LARS remains a lifelong challenge, significantly impacting their quality of life. Nighttime symptoms of LARS, in particular, have a profound effect on sleep quality, potentially leading to a decline in overall quality of life. Currently, there is no definitive method to completely cure LARS, and the available approaches focus on empirical treatments or short-term symptom control using medications such as loperamide. Loperamide directly affects the neuromuscular system of the intestine, reducing its motility. This prolongs the time food stays in the intestine, allowing sufficient absorption of moisture and electrolytes, consequently reducing symptoms of diarrhea. Loperamide is available in two forms: loperamide oxide and loperamide hydrochloride. While loperamide oxide products like Arestal® were prescribed by doctors until August 2017, the approval was revoked, leaving loperamide hydrochloride as the only form used domestically. It comes in a single product containing 2 mg of loperamide hydrochloride and a combination product with 0.25 mg of loperamide hydrochloride, a sterilizing agent in the intestine (e.g., acrylonitrile, berberine), and an antispasmodic. Transanal irrigation (TAI) is a method where patients self-administer water into the rectum through an enema, physically cleansing the anus and rectum. This technique is often used for patients with chronic constipation or fecal incontinence. TAI has proven beneficial, particularly in improving symptoms for patients experiencing bowel dysfunction following sphincter-preserving surgery, especially for those who underwent low anterior resection. However, there is currently no research on the utility and safety of TAI for LARS patients, specifically addressing whether it can improve the nighttime symptoms associated with LARS syndrome and enhance sleep quality. Therefore, this study aims to investigate the impact of TAI on the quality of sleep in patients with nighttime symptoms of LARS syndrome.
Low Anterior Resection Syndrome (LARS) is an intestinal disorder affecting patients undergoing rectal resection for rectal cancer. A possible therapeutic option may be Gelsectan®, a class II device used in Irritable Bowel Syndrome (IBS). The aim of this study is to evaluate the efficacy of Gelsectan® in improving the symptoms of LARS.
The purposes of this study are to explore the trajectory of symptom distress and balance ability in patients with rectal cancer.
The goal of this study is to compare the postoperative anal function of patients with ultra-low rectal cancer after Parks operation (colon anal anastomosis) and Bacon operation (colon anal pull-out anastomosis), which may provide clinical evidence for the improvement of anal function and quality of life. The main questions it aims to answer are: the difference of anal function 1 year after surgery type of study: clinical trial participant population: patients with low rectal cancer Participants will receive Parks operation of Bacon operation If there is a comparison group: Researchers will compare Parks and Bacon operation to see if the anal function 1 year after surgery is different.
Introduction: About 50% of patients who undergo rectal resection (mostly as a treatment for rectal cancer) suffer from various and partly severe functional problems, despite the preservation of the anal fold. These complaints are summarized as low anterior resection syndrome (LARS). So far, there are no randomized clinical trials that would definitively confirm or deny the hypothesis regarding the most effective treatment for LARS. Objectives: To evaluate whether transanal irrigation improves bowel function and quality of life in patients after rectal resection compared with the best supportive care. Methods and analysis: Patients who have undergone low anterior resection will be approached for this study. During the patient's visit, we will assess their complaints regarding defecation problems, as well as any deterioration in their overall quality of life. To gather this information, we will have the patients fill out questionnaires such as the LARS (Low Anterior Resection Syndrome) and Wexner scale, along with quality of life questionnaires. Questionnaires and scales will be filled out again during the visit every 3 months for 1 year. Discussion: This multicentre, randomized controlled trial will lead to a better understanding of LARS treatment. Moreover, it will be hypothesis generating and inform areas needing future prospective studies.
Sphincter sparing rectal resection surgery, either total mesorectal excision (TME) with a temporary loop ileostomy or partial mesorectal excision (PME), is the mainstay of rectal cancer treatment , however, these treatments are associated with the development of Low anterior resection syndrome (LARS). This syndrome is characterized by a constellation of symptoms such as fecal frequency, urgency and clustering of bowel movements and can lead to fecal and flatus incontinence. There is no gold standard therapy designed to treat the root cause of the problems associated with LARS. Paula Method of exercises, based on the theory that the body has the natural ability to self-heal and that all sphincter muscles in the body affect one another other and thus, exercising one healthy region can positively impact another. The purpose of this study is to evaluate the usefulness of the Paula Method of exercises in patients post sphincter sparing rectal resection surgery with LARS Syndrome.
The ACO-ASSO (Austrian Society of Surgical Oncology) colorectal group and Austrian Working Group for Coloproctology present the LARS Austria study. It is a prospective, multicenter observational study. The primary objective of this study is to collect information about LARS (LARS score) and QoL (EORTC -CR29) in patients with non-metastatic rectal cancer who received therapy. As a secondary objective, the impact of radiotherapy on the occurrence of LARS will be investigated.
This study aims to evaluate the incidence of low anterior resection syndrome and quality of life after cytoreductive surgery for advanced ovarian cancer patients.
The survival rate of colorectal cancer patients is increasing due to the development of medical technology. However, many colorectal cancer survivors (CRCs) have bowel dysfunction unlike other cancer survivors. After bowel dysfunction of CRCs was known, many previous studies were conducted to improve bowel dysfunction. Medication, probiotics, Biofeedback training (BFT), Kegel exercise, and sacral nerve stimulation were the methods of intervention research to improve bowel movements in CRCs. Research on randomized control trial of BFT and Kegel exercise is very insufficient. Surgery, chemo, and radiation have a lot of influence on the bowel process of CRCs. In particular, damage to the abdominal muscles, pelvic floor muscles, and autonomic nervous system can also be caused by secondary symptoms such as increased fatigue, reduced physical strength, and musculoskeletal diseases. Therefore, the investigators examine that exercise which can improve fatigue, physical fitness, and musculoskeletal disease affects bowel symptoms of colon cancer survivors.
The treatment of rectal cancer is currently based on surgical resection of the rectum with total excision of the mesorectum, associated with neoadjuvant radiochemotherapy. Surgical resections with sphincter preservation are frequently (60% of cases) associated with problems related to intestinal and defecatory function, which together are called Anterior Resection Syndrome (ARS) with varying degrees of severity. Among the different treatments the investigators find posterior tibial nerve stimulation, a simple and non-invasive technique, which is currently used. The study aims to analyze whether postoperative posterior tibial nerve stimulation in patients undergoing low anterior resection of the rectum has an impact on the incidence and duration of low anterior resection syndrome (LARS) and therefore on the quality of life of patients undergoing this type of intervention. Therefore, treatment with PNTS is currently established for the management of LARS symptoms. Given that a large percentage of patients operated on for rectal neoplasms will develop this syndrome, the investigators intend to apply this treatment before the onset of symptoms in patients at risk for LARS. It is also an intervention with a low rate of side effects, the benefit that the investigators can obtain from its preventive application is clearly superior to the risk of undergoing such treatment. The investigators´ hypothesis is: Posterior tibial stimulation for 6 weeks post-operative of low anterior resection with anastomosis has a favorable impact by reducing the incidence and duration of ARS and improving the quality of life of patients undergoing anterior rectal resections for cancer.
