Background: Low anterior resection syndrome LARS covers disordered bowel function after rectal resection, leading to deterioration in patients' quality of life. The aim of this study was to evaluate anorectal function after laparoscopic low anterior resection LAR by means of standardized instruments. Methods: This was a prospective clinical cohort study conducted in a single institution to assess functional outcome of patients 1 year after laparoscopic LAR by means of LARS score and high-resolution anorectal manometry. Results: In total, 65 patients were enrolled in the study. Mean tumour height was 9. One year after the surgery, minor LARS was detected in
Rectal manometry is performed to measure muscular function, anorectal sensitivity, and the stiffness compliance of the rectum. Rectal manometry is the most important test to diagnose faecal incontinence. It measures pressure and movements of the rectal sealing function and anal clamping function sphincter muscles. However, the test should also be conducted when a person experiences chronic constipation due to inadequate muscular relaxation of the sphincter. Instead of opening, during the intestine's squeezing contractions, the sphincter remains closed or may even tense up.
Anorectal manometry ARM is a medical test used to measure pressures in the anus and rectum and to assess their function. From to , the international anorectal physiology working group IAPWG meet several times to develop consensus on indications for anorectal manometry. Since its introduction in , high resolution anorectal manometry HR-ARM has increasingly replaced conventional anorectal manometry as the standard.
The aim of this study was to measure the rectal compliance in different patient groups compared with controls and to establish the clinical effect of rectal compliance. Normal values were obtained from 24 controls. Rectal compliance measurement was performed by filling a latex rectal balloon with water at a rate of 60 ml per minute.
