Solitary rectal ulcer syndrome—The role of autofluorescence colonoscopy

Solitary rectal ulcer syndrome

“…Patients typically complain of rectal pain, rectal prolapse, bleeding, pain, tenesmus, mucus, chronic and severe constipation, lengthened straining on defecation, pelvic discomfort as well as a sense of incomplete evacuation. [5,11] Nonetheless, it has been suggested that up to 26% of patients may be asymptomatic. [14] The most common clinical symptom is reported to be rectal bleeding.…”

“…[17] Self-induced trauma has been reported in people who have been trying to remove stools by rectal digitation. [11,18,19]…”

“…It has been stated that the most important theories are associated with direct trauma or causes of local ischemia. [11] Straining: Lengthened straining during bowel movements in the patient who suffers from constipation may result in a direct trauma to the mucosa. [20] Self-induced trauma: self-instrumentation can be occurred when individuals attempt to remove impacted stool by rectal digitation.…”

“…[20] Self-induced trauma: self-instrumentation can be occurred when individuals attempt to remove impacted stool by rectal digitation. [11,18] Paradoxical contraction of puborectalis muscle : Uncoordinated muscle contraction in the puborectalis muscle has been indicated to be associated with increased intrarectum pressure and anal canal, resulting in ischemic production and ulceration. [8,11] Rectal prolapse and intussusception: Rectal intussusception can lead to localized vascular trauma and consequently the onset of solitary local ulceration.…”

“…Autofluorescence colonoscopy by means of the Onco‐LIFE system appears to be a promising approach in diagnosis of SRUS. The estimation of numerical color value, which is an objective test of autofluorescence intensity, facilitates the differential diagnosis and helps to choose the right management of SRUS (80).…”
