Abstrakt: Background: Laser Hemorrhoidoplasty (LHP) is a minimally invasive surgical option for the management of hemorrhoidal disease that has been increasingly adopted by surgeons over the last decade. Two wavelengths; 980 nm and 1470 nm have been employed in LHP. However, no data exist comparing the effects of these two wavelengths for this indication. This systematic review investigates both wavelengths for the management of hemorrhoids via the LHP procedure.
Methods: This systematic analysis and meta-analysis was performed following the PICOS and PRISMA guidelines. A systematic research of MEDLINE, Scopus, Clinicaltrials.gov, Embase, Cochrane Central Register of Controlled Trials, CENTRAL and Google Scholar databases from inception until March 2024 was performed.
Results: Overall, 19 studies including seven randomized control trials (RCT) and 12 non-randomized control trials with a total of 2492 patients were included in this systematic review and meta-analysis. The duration of LHP with both wavelengths was significantly shorter compared to open hemorrhoidectomy, postoperative pain and the rate of postoperative complications were significantly lower following LHP. There was no statistically significant difference in the rate of recurrence between LHP with the 980-nm wavelength and open hemorrhoidectomy. However, LHP with 1470-nm wavelength resulted in significantly higher recurrence rate compared to hemorrhoidectomy.
Conclusion: Although no direct studies have compared the two wavelengths used in LHP, the outcomes of LHP seem to be independent of the wavelength used. Both wavelengths, when correctly used provide similar results, which are mostly better compared to open hemorrhoidectomy in terms of postoperative complications and postoperative pain, but not in terms of recurrence, where at least for the 1470-nm wavelength, LHP seems to show a higher recurrence rate when compared to open hemorrhoidectomy. Although a direct comparison of both wavelengths was not possible, technical issues regarding number of shots and energy per pile represent relevant parameters for recurrence after LHP.
