Abstract

Anococcygeal ligament (ACL) determines the spatial anorectal configuration due to traction and counter-traction mechanism of anal continence, and namely due to compression and displacement of the rectum characterized by its displacement with respect to points of fixation to osteoligamentous apparatus of the small pelvis, and that is why any surgical intervention, which includes removing even a small component of this complex, inevitably leads to functional disturbance of continence after the intervention.
Objective: to determine functional disorders of anal sphincter apparatus in case of ACL damage or its plastic surgery.
Material and methods. We have conducted a retrospective study of the treatment outcomes in patients who were treated in the clinic, 15 of them underwent coccygectomy with ACL resection, and 13 patients had ACL plasty. By creating a spatial mathematical model of ACL function it was established that in case of its damage the anorectal angle can be decreased up to +63°, which leads to functional disorders of distal segments of large intestine.
Results. The conducted studies confirmed that the main component of preventing defecation disorders in this group of patients must be the intraoperative removal of rectococcygeal cavity with ACL plastic surgery in order to repair the continuity of musculoligamentous apparatus by imitating its anatomical fixation.
Conclusions. Repair by imitating anatomical fixation of anococcygeal ligament junction after intraoperative damage allows creating conditions for its physiological functioning, which, in its turn, helps to prevent defecation disorders.
