Aim of the study: To evaluate the effects of warm water sitz bath on post-hemorrhoidectomy symptoms. Patients and Methods: Research design: Prospective randomized controlled trial. Setting: General Surgery Wards and Outpatient Clinics of General Surgery at Assiut University Hospital. Sample: A random sample of 60 adult patients with hemorrhoids (grade III or IV) that did not respond to conservative treatment and consequently had undergone hemorrhoidectomy. Patients were randomly assigned to study group and control group, 30 patients for each group. Tools: Tool I: Patient assessment sheet: Tool II: Symptoms assessment sheet. Results: A significant improvement in the level of pain and anal burning during the 4 weeks follow-up period that was more apparent in the study group than in the control group (p0.01). A noticeable improvement of anal itching was found in both groups but it was higher in the study group more than the control one; however, it reached a statistically significant level at the third and fourth week. Wound healing was higher among the study group when compared with the control group. Conclusion: Warm water sitz bath had a statistically significant effect on improvement of posthemorrhoidectomy pain, anal burning, and anal irritation.
