Podiatry Laser Surgery / Laser Therapy For Hemorrhoid Treatment - LHP
Hemorrhoidal disease is ranked first amongst diseases of the rectum and large intestine, and the estimated worldwide prevalence ranges from 2.9% to 27.9%, of which more than 4% are symptomatic. Approximately, one third of these patients seek physicians for advice. Age distribution demonstrates a Gaussian distribution with a peak incidence between 45 and 65 years with subsequent decline after 65 years. Men are more frequently affected than women. The anorectal vascular cushions along with the internal anal sphincter are essential in the maintenance of continence by providing soft tissue support and keeping the anal canal closed tightly. Hemorrhoids are considered to be due to the downward displacement suspensory (Treitz) muscle. The treatment options for symptomatic hemorrhoids have varied over time. Measures have included conservative medical management, non-surgical treatments and various surgical techniques. The various non-surgical treatments include rubber band ligation (RBL), injection sclerotherapy, cryotherapy,Laser hemorrhoids coagulation, laser therapy and diathermy coagulation; all of which may be performed as out patient procedures without anaesthesia. These nonsurgical methods are considered to be the primary option for grades one to three (grade I-III) hemorrhoids. If conservative measures fail to control symptoms, patients may be referred to a surgeon for operative management. The indications for the surgical treatment include the presence of a significant external component, hypertrophied papillae, associated fissure, extensive thrombosis or recurrence of symptoms after repeated RBL. Post hemorrhoidectomy pain is the commonest problem associated with the surgical techniques. The other early complications are urinary retention (20.1%), bleeding (secondary or reactionary) (2.4%–6%) and subcutaneous abscess (0.5%). The long-term complications include anal fissure (1% -2.6%), anal stenosis (1%), incontinence (0.4%), fistula (0.5%) and recurrence of hemorrhoids.
Laser Hemorrhoidoplasty (LHP)
Hemorrhoid laser procedure is a new laser procedure for outpatient treatment of hemorrhoids in which hemorrhoidal arterial flow feeding the hemorrhoidal plexus is stopped by means of Doppler-guided laser coagulation.
In the hemorrhoid laser procedure operation, With the patient in the lithotomy position, a Doppler probe was inserted into the anal canal through a dedicated disposable proctoscope to identify the terminal branches of superior hemorrhoidal arteries approximately 3 cm above the dentate line. Five pulsed laser shots with a 980-diode laser were delivered to each identified artery through the proctoscope to close the terminal branches. The procedure was repeated for each artery through clockwise rotation of the proctoscope. The depth of shrinkage can be regulated by the power and duration of the laser beam.
As far as pain is concerned, early postoperative pain is dominantly lower in the LHP group compared with surgical group. The same values also resulted for the period of one month. laser hemorrhoidectomy had the advantages of being haemostatic, bactericidal, fast healing, not affecting neighboring structures, less postoperative complications and less hemorrhage and stenosis
Laser hemorrhoidectomy is associated with lesser duration time compared with open surgical hemorrhoidectomy, which is satisfactory for symptomatic hemorrhoidal patients with III or IV stage (15.94 vs. 26.76 min). Laser hemorrhoidoplasty procedure is more preferred in comparison with conventional open surgical hemorrhoidectomy. Postoperative pain is significantly lesser in laser procedure compared with surgical procedure. Duration time is significantly shorter in laser procedure.
