Laser hemorrhoidoplasty (LHP) is a minimally invasive technique that uses targeted laser energy to treat internal hemorrhoids from within, aiming to reduce tissue volume without excising the hemorrhoidal columns or their overlying mucosa. Among the various wavelengths used in laser medicine, 1470 nm has become a common choice for this application due to its particular absorption characteristics in tissue. This article explains how the procedure works and where it fits among hemorrhoid treatment choices.
What Happens During Laser Hemorrhoidoplasty?
During LHP, a thin laser fiber is inserted directly into the hemorrhoidal tissue, typically through a small puncture rather than an open incision. The laser then delivers energy along the length of the treated column in a controlled fashion, generating localized heat that causes the tissue to gradually shrink and fibrose over subsequent weeks. Because the fiber is introduced through a puncture rather than a cutting instrument, the overlying anal mucosa and skin are generally preserved, which is one of the features distinguishing LHP from traditional excisional hemorrhoidectomy.
Why Is 1470 nm Wavelength Commonly Used?
The 1470 nm wavelength is notable for a relatively strong absorption peak in water, a major component of soft tissue. This property allows the laser energy to be absorbed efficiently within a limited tissue depth, which can support a more controlled, localized thermal effect compared with some other wavelengths. This absorption characteristic is one reason 1470 nm lasers have found broader adoption not only in hemorrhoidal treatment but also in other soft-tissue and vascular laser applications, since predictable energy absorption supports more consistent treatment outcomes across cases.
How Does LHP Compare to Traditional Hemorrhoidectomy?
Traditional hemorrhoidectomy involves surgical excision of hemorrhoidal tissue and is generally associated with a more significant postoperative recovery period due to the surgical wound created. LHP, by preserving the mucosal surface and avoiding a large excisional wound, is often associated with a different recovery profile, with many patients reporting less immediate postoperative pain. However, LHP is not a universal replacement for excisional surgery — it is generally considered more suitable for lower to moderate grade hemorrhoids, while more advanced prolapse with significant redundant tissue may still be better addressed through excisional or stapling techniques. The appropriate choice depends on hemorrhoid grade and the treating surgeon's assessment.
What Does Recovery From LHP Typically Involve?
Because LHP avoids an open surgical wound, many patients experience a comparatively shorter period of significant discomfort, though some soreness, mild swelling, or minor bleeding in the days following the procedure is commonly reported. Most patients are able to resume normal activities relatively quickly compared with excisional surgery, though the exact timeline depends on the number of columns treated and individual healing response. As with any hemorrhoid procedure, follow-up with the treating physician helps confirm that healing is progressing as expected.
Who Might Be a Candidate for Laser Hemorrhoidoplasty?
LHP is generally considered for patients with symptomatic internal hemorrhoids, often grade II–III, who are seeking an option that avoids open excision. Patient anatomy, hemorrhoid grade, and prior treatment history all factor into whether this technique is appropriate for a given individual, and a qualified physician determines suitability following a direct clinical examination.
Can laser hemorrhoidoplasty be combined with other hemorrhoid treatments?
In some cases, LHP may be used alongside other techniques, such as rubber band ligation for an accompanying prolapse component, depending on the individual presentation. This decision is made by the treating colorectal surgeon based on the full clinical picture.
