Solitary Rectal Ulcer Syndrome: A Narrative Review

Solitary rectal ulcer syndrome is a multifactorial pathology, which entails a variety of clinical, histologic and endoscopic aspects that needs step-wise logical approach for management especially in relapsing refractory cases. Apart from the diagnostic dilemma that may be faced due to similarities of presentation with inflammatory bowel diseases or colorectal neoplastic lesions, the syndrome also overlaps with dyssynergic defecation syndrome, health anxiety disorder, obsessive compulsive disorder, and latent mucosal rectal prolapse, a systematic composite treatment modality including psychological, pharmacological, physiological and possibly surgical interventions are sometimes essential. Selecting appropriate treatment in this condition not only affects clinical outcome but also patients’ experience and further stigma of SRUS life-long. In this review, we will discuss the detailed pathophysiology, diagnostic and therapeutic approaches in dealing with solitary rectal ulcer syndrome.

Effective treatment of solitary rectal ulcer syndrome using argon plasma coagulation

Solitary rectal ulcer syndrome (SRUS) is a chronic, multiform, non-cancerous disorder of the rectum, the final diagnosis of which is based upon histopathological criteria. This disorder is often accompanied by latent proctoptosis. We present a patient who (in 1996) was the first case in which argon plasma coagulation (APC) was used for SRUS treatment. In the years 2004–2005 the same patient underwent 15 APC sessions (at monthly intervals) obtaining full recovery from SRUS, although she had been treated unsuccessfully for 17 years prior to that. Six-year observation did not show any relapse. Local therapy with APC seems to be an important alternative in SRUS treatment without prolapse of the rectum and could become a basic method for bleeding treatment in SRUS.
