Abstract
Background
Laser treatment is increasingly used in the treatment of symptomatic hemorrhoids, and several studies have attempted to describe its clinical outcomes. In this systematic review, we aimed to comprehensively analyze the clinical outcomes and effectiveness of laser treatment.
Methods
We performed a systematic review of currently available data on laser treatment for hemorrhoids. We searched MEDLINE and Google Scholar between January 2009 and May 2020. Studies that described the clinical outcomes and effectiveness of laser treatment were selected based on pre-specified inclusion criteria with a minimum follow-up period of 3 months. Qualitative synthesis of the clinical outcomes, effectiveness and complications was performed.
Results
Nineteen studies including 1937 patients were analyzed. The majority were males (n = 1239) and included grade 2 and 3 hemorrhoids. In the majority (n = 1750, 90.34%), the 980 nm wave length diode laser was used as the energy source. Doppler-guided localization was performed in six studies (n = 579, 29.89%). All studies (n = 1937) reported low postoperative pain scores and nine studies (n = 1131) showed significantly lower pain compared to open technique. Furthermore, six studies (n = 1023) showed significantly less intra- and postoperative bleeding compared to open technique. Seven studies (n = 1052) reported long-term follow-up results and were found to be satisfactory in terms of symptom relief and recurrence. This study was limited by heterogeneity of outcomes precluding a meta-analysis.
Conclusion
Laser treatment had acceptable clinical outcomes for grade 2 and 3 hemorrhoids with lower rates of postoperative pain and bleeding with satisfactory long-term outcomes.
