Sumario:Background: Solitary rectal ulcer syndrome (SRUS) is a benign rectal condition associated with defecation disorder that has multifactor pathologies and variable findings on presentation, endoscopy, and histopathology. A diagnostic dilemma with an overlap of differentials and step-wise management that starts with conservative therapies and goes up to repeated surgeries in case of failure of the conservative approach. Objective: This study aims to observe clinical, endoscopic, and histological features of SRUS in patients presenting with lower gastrointestinal bleeding. Material and methods: The study was conducted at the Department of Gastroenterology, Medical Teaching Institute, Lady Reading Hospital Peshawar from October 2018 to April 2020. After written informed consent, 257 patients (149 males and 108 females) from ages 15 to 70 who presented with lower GI bleeding were included via non-probability convenient sampling. Sociodemographic details were recorded in a pre-designed proforma. A colonoscopy was performed with the Colonoscope CF200 Z, Olympus Tokyo, Japan, and findings were noted. Suspected lesions were magnified, dyed with 0.2% indigo carmine, biopsied from the middle and edges of the ulcer, and sent for histopathology. All data were recorded and analyzed in SPSS-20. The mean with SD was calculated for quantitative variables, and frequency and percentages were calculated for qualitative variables. The chi-square test was used to check the significance, and a p-value of <0.05 was considered statistically significant. Results: SRUS was found in 17 (6.6%) patients with lower GI bleeding, with a male predominance of 57% (n=11). Perirectal bleeding, constipation, mucous discharge, abdominal pain, and anemia were common clinical findings. Solitary lesions, ulceration, and anterior rectum location were the most common endoscopy findings. Obliterated lamina propria with collagen, ulceration, crypt distortion, and inflammatory infiltrates were common histopathological findings. Conclusion: SRUS is a benign defecation disorder commonly presenting with lower GI bleeding, constipation, straining, and abdominal pain. It needs a stepwise approach with conservative management, medical management, biofeedback, and surgeries as a last resort.
