RecruitingPhase 3Clinical trialImproving Functional Outcomes and Quality of Life in Patients With Rectal Cancer After Surgery With Intensified Follow-up & SurveillanceThe 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.
