Streszczenie
Według szacunkowych danych dolegliwości związane z chorobą hemoroidalną dotyczą ponad połowy populacji po 50. roku życia. Do głównych objawów choroby hemoroidalnej należą: krwawienia, wypadanie hemoroidów, dyskomfort, pieczenie i swędzenie oraz uczucie niepełnego wypróżnienia. Różnorodne nasilenie objawów zależne jest od wielu czynników. Celem leczenia choroby hemoroidalnej jest przede wszystkim ograniczenie dolegliwości, co można uzyskać leczeniem zachowawczym, zabiegowym lub operacyjnym. Wskazaniem do leczenia zabiegowego jest choroba hemoroidalna w stopniu II i III, objawowa, w której leczenie zachowawcze nie przynosi oczekiwanego efektu lub gdy efekt leczenia zachowawczego jest jedynie krótkotrwały. Poszukiwania alternatywnych metod leczenia guzków krwawniczych przynoszą nowe rozwiązania lub kolejne modyfikacje już istniejących sposobów leczenia mające na celu poprawę wyników i indywidualizację leczenia. Do alternatywnych metod leczenia guzków krwawniczych należą: metoda Barrona, skleroterapia, DGHAL, krioterapia, diatermia jednobiegunowa i niskonapięciowa (met. Hemoron), elektrokoagulacja bipolarna, laser CO2, diodowy oraz neodymowo-yagowy. W artykule przedstawiono aktualne dane dotyczące skuteczności poszczególnych metod w oparciu o najnowsze piśmiennictwo i wyniki publikowanych badań. Autorzy zwracają również uwagę na ograniczenia i specyficzne dla poszczególnych metod powikłania.
Summary
It is estimated that haemorrhoids affect more than half of the population over 50 years of age. The main symptoms of haemorrhoidal disease include bleeding, haemorrhoidal prolapse, discomfort, burning, itching and a feeling of incomplete evacuation. The severity of symptoms depends on many factors. The treatment of haemorrhoidal disease is primarily aimed to limit the symptoms, which can be achieved via conservative, interventional or surgical treatment. Indications for interventional treatment include symptomatic stage II and III haemorrhoidal disease when conservative therapy does not bring the desired effect, or the effect is only temporary. The search for alternative methods for the treatment of haemorrhoids results in new solutions as well as further modifications of the existing treatments, which is aimed at therapeutic outcome improvement and treatment individualisation. Alternative interventional therapies include Barron’s method, Sclerotherapy, DGHAL, cryotherapy, unipolar and low-voltage diathermy (Hemoron), bipolar electrocautery, CO2, diode and Nd:YAG laser. The article presents current data on the effectiveness of these methods based on the latest literature and published studies. The authors also point to limitations and complications associated with the described methods.
Introduction
It is estimated that haemorrhoids affect more than half of the population over 50 years of age. The main symptoms of haemorrhoidal disease include bleeding, discomfort, burning, itching and a feeling of incomplete evacuation. Pain and haemorrhoidal prolapse can occur in later stages of the disease. The varying severity of the symptoms depends on many factors, such as, primarily, the stage of the disease, but also diet, age, sports activity, type of work and genetic predispositions. The treatment of haemorrhoidal disease is mainly aimed to limit the symptoms. In most cases, conservative or interventional treatment is sufficient. At present, only 10% of patients require surgical treatment. Indications for alternative interventional treatment include symptomatic stage II and III haemorrhoidal disease when conservative therapy does not bring the desired effect, or the effect is only temporary. In exceptional cases, interventional treatment is used in patients with stage IV haemorrhoidal disease, particularly in patients not qualified for surgical treatment due to age or multiple comorbidities. The lack of patient’s consent for surgical treatment, which often results from the fear of potential postoperative pain and complications, sphincter dysfunction in particular, is another indication for interventional treatment. For centuries, the search for alternative methods for the treatment of haemorrhoids have brought new solutions or further modifications of the existing treatments (1). The aim of these measures is to improve treatment outcomes and allow for tailoring therapy for individual patients. Efficacy assessments for a given technique found in the literature are based on the rate of recurrence as well as the incidence and the type of complications. Methods for interventional treatment of haemorrhoidal disease are presented in table 1.

Although the Barron’s method (rubber band ligation – RBL) was first described in 1963, it is still one of the most popular non-surgical procedures for the treatment of haemorrhoids (2). This popularity is due to the low costs, acceptable efficacy and low complication rate. The technique involves placing a rubber-band around the base of the haemorrhoid using a special cylindrical ligator. The haemorrhoidal tissue is pulled into a cylinder to allow the placement of rubber bands around the base of the haemorrhoid. As a result, ischemia develops, leading to haemorrhoid fibrosis, necrosis and spontaneous amputation (3). Patients with stage II and III haemorrhoids, particularly those complaining of bleeding or haemorrhoidal prolapse, are qualified for the procedure. Providing the patient with detailed information about the course of the procedure as well as symptoms that may occur during the procedure is an important element of this type of treatment. Moderate pain, minor bleeding after several days or tenesmus are expected symptoms that usually resolve after 1 or 2 days and should not cause anxiety. Prolonged symptoms, lack of response to pharmacotherapy or increased temperature should be alarming for patients, who should contact their doctor. The need to repeat the procedure several times in order to achieve the desired effect is an inconvenience of this technique. Usually, one rubber band is placed on a single haemorrhoid. Once the wound has healed, another rubber band is placed on another haemorrhoid (fig. 1).

Sclerotherapy is also one of the most commonly used methods in the treatment of haemorrhoids. Haemorrhoid fibrosis occurs as a result of inflammatory response to the injected obliterating agent into the submucosal layer at the base of the haemorrhoid. A simple anoscope or an anoscope featuring special canal for the injection needle is used in the procedure (4). Obliterating preparations have changed over the years. The name of the procedure was determined by the type of obliterating preparation – Blanchard’s method used 5% phenol in almond oil, while an injection of quinine urethane was used in the Blond method (5, 6). Presently, 3% polidocanol is the most popular preparation. Obliterating preparation is administered in the form of fluid or foam. A simultaneous injection of all haemorrhoids, which allows for a quick effect and limits the need for repeated medical appointments, is an advantage of the method. Proper administration of the agent into the submucosal layer is an important technical aspect of this method. Deeper injection can lead to complications, such as inflammation and even local necrosis (fig. 2).

DGHAL requires local, peripheral or general anaesthesia and involves ligation of the vessels that supply haemorrhoids using a special Doppler-equipped anoscope (7). Limitation of indications to early stage disease is a disadvantage of the method. Patients with stage II non-prolapsed haemorrhoids are qualified for this treatment. The technique is additionally limited by high costs. In patients with prolapsing haemorrhoids, DGHAL can be combined with recto-anal-repair (RAR), which involves lifting and fixing the prolapsing mucosa into its correct position, which reduces the prolapse.
