Search for: [Abstract = "Approximately 70 % of patients after low anterior resection of rectum report embarrassing rectoanal dysfunctions \(in form of various degrees of faecal incontinence\) so\-called low anterior resection syndrome \(LARS\). Disturbances in sphincters innervation as an implication of sugery can play the main goal in the etiology of LARS. The primary aim was to assess the influence of oncological treatment on motor functions evaluated with superficial multi\-channel electromyography \(sEMG\) and evaluation of influence of the extend of resection of the rectum on spatio\-temporal sEMG registration with consideration of time trends. The following secondary aim was\: determination of the correlation between sEMG \(RMS, MNF\) parameters and the results of anorectal manometry \(MRP, MSP, RAIR\) with the degree of faecal incontinence measured in FISI range. A total of 35 rectal cancer patients \(M\:F\: 28\/7\; age 6511.4\) were included into the study. sEMG parameters, manometric measures and clinical evaluation \(FISI\) were performed during qualification for the treatment and 1, 6 and 12 months after surgery. The patients qualified to pre\-operative radiotherapy were also examined before and 6 days after radiotherapy. A Three ring \(48 channel\) anorectal probe connected with 16 channels EMG–amplifier 16 II BF was used for sEMG recording \(OT Bioelettronica, Torino, Italy\). Two independent measures were assessed"]
