Patient characteristics. The characteristics of the PPS patients and normal patients are shown in Table 1.A total of 72 patients who met the study criteria, including 26 men and 46 women with a mean age of 54.1 ± 14.5 years (range, 14-77 years), were included in the study. The puborectalis is a muscle of the pelvic floor. It is part of the levator ani muscle group, and the most important for maintaining faecal continence. Attachments: Originates from the posterior surface of the pubis. It forms a U-shaped sling around the anal canal, and attaches to the pubis on the contralateral side. Levator ani muscle (Musculus levator ani) The levator ani is a broad muscular sheet located in the pelvis.Together with the coccygeus muscle and their associated fascias it forms the pelvic diaphragm.. The levator ani is collection of three muscles: puborectalis (puboanalis), pubococcygeus, and iliococcygeus. The function of the entire levator ani muscle is crucial, in that it stabilizes the The concept that the puborectalis muscle is anatomically a part of the external anal sphincter muscle, rather than the levator ani muscle has been previously proposed from a cadaver study. 2. Although the puborectalis and external anal sphincter muscle form a functional unit in maintaining continence, developmental studies provide evidence that Anismus or non-relaxing puborectalis muscle (PRM) on straining may affect over 40% of patients with obstructed defecation (OD). Management is usually with biofeedback, or botulin toxin injection or partial puborectalis muscle myotomy. Such a procedure can be difficult technically. Bleeding and rectal injury may occur when detaching the PRM from the rectum.
