Abstract
Purpose
Hemorrhoidectomy remains the gold standard treatment for grade III–IV hemorrhoids. However, despite strong recommendations for the suitability of outpatient surgery, post-operative pain has been a limitation to the widespread inclusion of this condition in day surgery programs.
The aims of the study were to analyze and compare the post-operative pain of conventional open hemorrhoidectomy, considered the reference technique, against other surgical procedures such as closed hemorrhoidectomy, open hemorrhoidectomy using bipolar or ultrasonic sealant, hemorrhoidopexy, or HAL-RAR, when performed exclusively as outpatients.
Methods
A systematic review and meta-analysis was conducted according to PRISMA methodology. All prospective and randomized studies of patients operated on for hemorrhoids in day surgery and specifying the value of post-operative pain, using a validated scale, were included. Conventional meta-analyses and a random-effects network meta-analysis were carried out.
Results
Twenty-nine studies were included (3309 patients). None of the procedures described severe pain in the post-operative period. Hemorrhoidopexy was the least painful. Conventional open hemorrhoidectomy was the most painful on the first and seventh post-operative days. Pain was reduced after closed hemorrhoidectomy technique and when bipolar or harmonic scalpel was used. Furthermore, transfixive ligation of the hemorrhoidal pedicle was associated with increased post-operative pain.
Conclusion
Hemorrhoidal surgery is feasible in day surgery units and post-operative pain can be adequately managed in an outpatient setting. Hemorrhoidopexy was the least painful; however, data should be carefully evaluated by the high rate of long-term recurrence described in literature. Closed hemorrhoidectomy, performed with bipolar or ultrasonic sealing, avoiding transfixive ligation of the hemorrhoidal pedicle, may improve post-operative pain control.
