Bipolar diathermy involves the use of electrical current to coagulate the hemorrhoids, including the mucosa and submucosa. The machine generates a 2-second pulse of energy to accomplish the treatment. This approach is applicable for small bleeding hemorrhoids and probably has no greater efficacy than sclerosing.
Other variations on the use of energy to scarify internal hemorrhoids and fix them to underlying tissues includes infrared coagulation and direct current therapy or Ultroid (Microvasive, Boston, MA) therapy. Infrared coagulation uses a tungsten halogen lamp that generates heat energy for 1.5 seconds, resulting in destruction of the mucosa and submucosa at the application site . The depth of penetration of this injury is usually 3 mm. Conversely, the Ultroid uses electrical current that is applied for up to 10 minutes per complex treated. Ultimately, these new modalities are a variation on the theme of local tissue destruction and fixation of the hemorrhoids at the appropriate level.
A new entry into the arena of excisional hemorrhoidectomy is the circular stapled hemorrhoidectomy .The technique uses a circular, transanally placed pursestring suture 4 cm from the dentate line and within the enlarged internal hemorrhoids. A 31-mm stapler is then placed transanally to perform a circumferential excision of the hemorrhoidal tissue and a repositioning and fixation of the anoderm to its proper location in the anal canal. The results appear promising, with decreased postoperative pain, shorter periods of convalescence, and similar complication rates compared with other forms of excisional hemorrhoidectomy.
Although sclerotherapy, first advocated by Mitchell in 1871, has been used often in hemorrhoids, it is rarely performed in the United States.The purpose of sclerotherapy is to scar the submucosa, resulting in atrophy of the tissue injected and scarification with fixation of the hemorrhoidal complex within its normal location in the anal canal. A variety of solutions have been advocated, although it appears that sodium morrhuate and sodium tetradechol sulfate predominate. This modality is most effective in situations with minimal enlargement of hemorrhoidal complexes where the primary complaint is bright red rectal bleeding.
The procedure is performed with the patient in the left lateral decubitus position. An anoscope is inserted to clearly identify the symptomatic complex, and a 25-gauge spinal needle is used to instill the sclerosant into the submucosal space . The syrine should be aspirated before injection to avoid a direct intravascular injection. Typically, 1 to 2 ml of sclerosant is adequate. The surgeon can inject as many locations as desired because the procedure is essentially painless. It is important, however, not to circumferentially inject the anal canal, because this may induce stricture formation.
The majority of patients evaluated for hematochezia that ultimately proves to be hemorrhoidal in origin can be and should be managed with fiber supplementation. Although it is not clearly proved that constipation contributes to hemorrhoidal symptoms, it is certainly reasonable to improve bowel function to reduce hemorrhoidal complaints in the majority of early-stage patients. The remaining nonoperative and operative interventions should be reserved for patients with advanced hemorrhoids and patients who are unresponsive to this simple but effective medical management routine.
Barron was the first to describe hemorrhoidal banding with rubber bands in 1963.Since this original description, there have been a number of reports that have documented the efficacy banding offers for the management of the majority of patients with bleeding stage II and III internal hemorrhoids.The procedure is generally well tolerated without the need for prescription analgesia if the band is placed above the level of the dentate line. The technique is demonstrated in the picture below . It is important to ask the patient if he or she experiences any pain during placement of the bander, before deployment of the band. Discomfort immediately after band placement may be reduced by the injection of a local anesthetic agent, but this does not appear to be a long-lasting benefit. Banding is associated with the rare but frequently fatal complication of postbanding sepsis, which is heralded by the symptoms of increasing rectal pain, fever, and inability to void.It is essential to treat these symptoms early and aggressively with early antibiotic treatment coupled with surgical drainage
Options for hemorrhoidectomy include the techniques of Milligan-Morgan hemorrhoidectomy, closed Ferguson hemorrhoidectomy, Whitehead hemorrhoidectomy, and the stapled hemorrhoidectomy. The procedures are usually performed in the operating room after minimal preoperative preparation of the bowel. Lasers have no role to play in excisional hemorrhoidectomy, and in fact they cause delayed healing, increased pain, and increased cost.Anesthetic management is usually left to the anesthesiologist and patient; however, local anesthesia supplemented by the administration of intravenous narcotics and propofol is very effective. The use of spinal anesthesia, although effective, may increase the risk of postoperative urinary retention.
The Milligan-Morgan hemorrhoidectomy, which is widely practiced in Europe, was originally described in 1937, and its efficacy has been subsequently documented in many series.This technique includes resection of the entire enlarged internal hemorrhoid complex, ligation of the arterial pedicle, and preservation of the intervening anoderm.[33] The distal anoderm and external skin is left open to minimize the risk of infection in the wounds. This technique is safe and effective. However, the fact that the external wounds are left open can be a cause of considerable discomfort and prolonged morbidity.
