Assessments of Pudendal Motor and Sensory Nerves in Patients with or without Fecal Incontinence after Low Anterior Resection for Lower Rectal Cancer
Background:?To clarify the pudendal motor (PMN) and sensory (PSN) nerves?play in preventing fecal incontinence (FI) after low anterior resection (LAR) for lower rectal cancer, the PMN and PSN functions were studied. Methods:?Sixty patients were divided into groups A (n = 20, FI) and B (n = 40, continence). These were compared with group C (n = 30, control subjects). PMN latency (PMNL) (right, left, and posterior sides of the anal canal) was studied by sacral magnetic stimulation. Anal mucosal electric sensitivity (AMES) was measured at the lower, dentate line (DL), and upper zones. Results:?The distance of anastomosis from anal verge (DAAV) in group A was significantly shorter than in group B (p?value p?value p?value p?value Conclusion:?FI after LAR with a short DAAV?may?lead to?external anal sphincter dysfunction due to damage of both PMN and PSN.
