Background and study  Aim: Endoscopic ultrasound (EUS) demarcates several layers of the gastrointestinal ‎wall, with little reports about its use as a diagnostic modality for rectal and ‎perirectal lesions. So, we aimed to evaluate its role in diagnosis of rectal and ‎perirectal lesions‎.‎
Patients and Methods: ‎‎‎ During the period between 2017 and 2019, a cross-sectional study was done. ‎Seventy adult patients included in the study who had rectal and/or perirectal ‎lesions. All the 70 patients had rectal EUS. Out of the 70 patients, EUS-FNA was ‎performed for 26 patients where it was possible and the wall was thick enough to ‎allow for sampling (>7mm)‎.‎
Results: Mean age of the study population was 51.91 ± 9.90 years, with a range of age ‎between 26 and 69 years. There was a perfect agreement (Kappa Agreement = 1) ‎with statistically significant difference between EUS diagnosis, EUS-FNA ‎diagnosis and final diagnosis. There was a perfect agreement (Kappa Agreement = ‎‎0.97) with statistically significant difference between presumptive diagnosis and ‎final diagnosis. Our study showed a relationship between EUS elastography and ‎the final diagnosis of the lesions where soft pattern corresponded to most of the ‎benign cases (67.60%) and firm pattern corresponded to most of the malignant ‎cases (78.70%)‎‎‎‎.
Conclusion: EUS is a useful diagnostic tool for rectal and perirectal lesions‎ ‎‎‎‎‎‎‎‎.
