Background/Aim:
Solitary rectal ulcer syndrome (SRUS) is a benign, chronic defecation disorder with varied presentations. The aim of this study is to summarize the clinical features, endoscopic findings, histological appearance, and treatment strategies associated with SRUS.
Patients And Methods:
This is a retrospective study of all patients diagnosed with SRUS at the King Faisal Specialist Hospital and Research Centre in Riyadh from January 2003 to December 2013. Cases were identified using the Department of Pathology database. Data were obtained from medical records that included clinical manifestation, endoscopic findings, and histopathological features.
Results:
Twenty patients were identified. The mean age was 42.5 years (±18.5) and 55% were females. Most of the patients presented with bleeding per rectum (85%), constipation (75%), and straining (50%), with a mean symptom duration of 26.7 months. The most common associated factors identified were constipation (75%), history of rectal surgery (25%), digital rectal manipulation (20%), and rectal prolapse (20%). Endoscopic findings included a single ulcer (50%) and multiple ulcers (30%); 55% had a polypoidal appearance. On histopathology, there was surface ulceration (95%), fibrosis of the lamina propria (60%), distorted architecture (55%), and muscle hypertrophy with increased mucin production (50%). Patients were treated conservatively and none required surgery.
Conclusion:
SRUS is a rare disorder with variable clinical presentations. Stool softeners, a high fiber diet in addition to topical mesalamine, and biofeedback proved to be effective in this patient population.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
