ABSTRACT
BACKGROUND: Conventional hemorrhoidectomy is still used for patients but a variety of less invasive treatments are also developed. Stapled hemorrhoidectomy is known as a beneficial technique. Here we aimed to evaluate and compare the results of stapled hemorrhoidectomy with conventional methods in patients who require hemorrhoidectomy. METHODS: This study was performed on 120 patients with stage 3 or 4 hemorrhoids. Mean resting pressure (MRP) and mean squeezing pressure (MSP) were measured before surgeries. Patients were then randomized into 2 groups of 60 patients. Group 1 underwent stapled hemorrhoidectomy and group 2 underwent conventional hemorrhoidectomy. The pain of patients was also determined using the visual analogue scale (VAS) for each patient 1, 2 and 3 days after the surgeries. Patients were then followed for 1 month after surgeries for evaluating the surgical outcomes, MRP and MSP. In terms of recurrence, they underwent clinical and anoscopic re-examination at least once in the next 6 months and 12 months after interventions. RESULTS: We showed that both MRP and MSP did not change significantly in both groups after interventions (P>0.05). We also observed a significant decline in the pain of both groups (P<0.001) and also a significantly lower pain in group 1 (P<0.05). Our data showed that patients in group 1 required less analgesic after procedures (P=0.001). Evaluation of recurrence rate 6 and 12 months after interventions showed that patients who underwent stapled hemorrhoidectomy had a significant higher recurrence rate within 12 months compared to the other group (P=0.003). CONCLUSION: Stapled hemorrhoidectomy is a safe and effective method that is associated with lower pain, hospitalization duration and no significant complications within 1 year follow-up. But on the other hand, this surgical method was associated with a higher recurrence rate.
