The goal of this clinical study is to gain further insights into the treatment of patients with Low Anterior Resection Syndrome (LARS) symptoms after rectal resection. The main question is: Can LARS symptoms and quality of life be improved by implementing an intensified follow-up program? Researchers will compare the results of the intervention group with the results of a control group in which patients do not receive an intensified follow-up program to determine whether the intervention works. Participants will undergo an intensified follow-up program which consists of several follow-up visits and medical treatment, pelvic floor muscle training and gynaecological and urological co-treatment in case of LARS symptoms and urinary or sexual complaints.
Background: After surgical treatment of patients with rectal cancer, up to 65% experience a symptom complex known as LARS (Low Anterior Resection Syndrome). Those affected suffer from symptoms such as fecal incontinence, frequent bowel movements and a strong urge to defecate, which can severely impair their quality of life. Therapy options include treatment with medication such as bulking agents or drugs that reduce bowel motility, pelvic floor muscle training or stimulation of the nerves that control the function of the rectum and pelvic floor.
Objective: The aim of the present study is to investigate whether an intensified follow-up program can improve the LARS symptoms and consequently the quality of life of patients after rectal resection. If the planned study shows success of the program, we will be able to structurally improve the aftercare of those affected.
Methods: The study is being conducted at several centers in Switzerland, including St. Claraspital Basel. Patients who have had a rectal resection are recruited prior to the repositioning of the artificial bowel outlet, which was created during the primary operation, and randomly assigned to one of the both study groups (intensified follow-up or standard treatment). The symptoms are recorded using various questionnaires and patients will be treated according to our action plan. If LARS symptoms occur, patients receive drug treatment, pelvic floor physiotherapy and, if necessary, sacral neurostimulation, which means implanting a device which stimulates the nerves that control the function of the rectum and pelvic floor. If patients suffer from urinary problems or impaired sexual function they will be referred to our urology or gynecology department for further diagnosis and treatment.

| Intensified follow-up program | Other | The study intervention will be an intensified follow-up program which consists of different measures. Patients will attend follow-up visits 1, 4, 7 and 13 months after ileostomy repositioning, at which LARS symptoms, quality of life as well as sexual and urinary function will be recorded using various questionnaires. In case of LARS symptoms patients will receive medical treatment with loperamide and metamucil as well as pelvic floor muscle training (including biofeedback and home exercises). Regarding pelvic floor muscle training we are planning nine sessions instructed by physiotherapy staff. In case of therapy-resistant LARS symptoms after 6 months sacral neurostimulation is offered to the patients with a focus on incontinence symptoms and desire for surgery or transanal irrigation in patients with a focus on voiding disorders. In case of urinary and sexual complaints patients are referred to our urology or gynaecology department for further diagnostic and treatment. |

| Improvement of the LARS score after 13 months | The primary outcome is the change of the LARS score after participation for 13 months in an intensified follow-up program compared to standard treatment which means patients are only treated if they present themselves in our consultation hours due to complaints. The LARS score is recorded using the LARS score questionnaire, developed 2012 by Emmertson et al.. The LARS score consists of five questions on the topics incontinence for flatus, incontinence for liquid stools, frequency of bowel movements, clustering of stools and urgency. Each answer results in a number of points, those points are summarized in the end to give a total score. This score is categorized into a range of no LARS (score 21 and lower), minor LARS (score 21 - 29) and major LARS (score 30 - 42). | 13 months after closure of ileostomy |
| Measure | Description | Time Frame |
|---|---|---|
| Patients' quality of life (QoL) | Patients' quality of life will be recorded using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Colorectal Cancer (EORTC-QLQ-CR29) which will be filled out by the patients before closure of ileostomy as well as 1, 4, 7 and 13 months after closure of ileostomy. Maximum score is 140 points, minimum score 35 points. Higher scores mean worse outcomes. |
