Effect of diode laser coagulation treatment on grade III internal hemorrhoids

OBJECTIVE:

To evaluate the curative effects of diode laser coagulation on grade III internal hemorrhoids.

METHODS:

From March 2004 to December 2004, 86 patients with grade III internal hemorrhoids were divided into two groups, received lasercoagulation (laser group, n=46) or received hemorrhoidectomy (control group, n=40). Complications, symptom relief, pain scores and satisfaction scores were compared between the two groups six months after operation.

RESULTS:

Pain scores were lower in laser group than that of the control group on the first day and seventh day after operation. Small amount of bleeding occurred in the laser group (12 cases) and control group (35 cases), however, non of them required special hemostasis. Laser coagulation and closed hemorrhoidectomy were equally effective in controlling symptomatic prolapse. There was no difference in terms of continence scores and patients satisfaction between the two groups (P> 0.05).

CONCLUSIONS:

Diode laser coagulation can be considered as a safe and effective procedure for the treatment of grade III hemorrhoids.

A new method for hemorrhoid surgery: experimental model of diode laser application in monkeys

OBJECTIVE:

Detailed here is an experimental model in monkeys of a new approach to treat hemorrhoids using a diode laser.

BACKGROUND DATA:

Hemorrhoids are a common source of pain and suffering. Endovascular laser therapy for variceal veins is a method that potentially could be used in the treatment of hemorrhoids. There is currently no such method described in the literature.

MATERIALS AND METHODS:

Hemorrhoids were induced in monkeys by ligation of the inferior hemorrhoidal vein, similar to their cause in humans. After the piles were identified, laser fibers were introduced into them, and they were irradiated with laser energy (810 nm at 1-2 W in 1-sec pulses of 1-2 J each, for a total fluency of 4-10 J).

RESULTS:

The piles were completely reduced, and histological examination performed 10 d post-surgery showed reduction of the dilated vessels and complete healing. The laser energy was not delivered directly into the veins, but instead to the surrounding submucosal interstitial tissue, effectively reducing the hemorrhoids.

CONCLUSION:

The diode laser energy delivered into the hemorrhoids led to their complete resolution. Further clinical trials using this protocol must be carried out to determine its applicability to human hemorrhoids.

Diode laser for treatment of symptomatic hemorrhoid

Hemorrhoid is protrusion of plexus or blood vessels in the anal canal. 

The hemorrhoid may cause symptoms that are: bleeding, pain, prolaps, itching, soilage of feces, and psychologic discomfort. There are many methods for treatment of hemorrhoid like, medical therapy, cryo-therapy, rubber band ligation, sclerotherapy, laser, and surgery. All methods have some complication in postoperative period and recurrence.

THE AIM OF THE STUDY:

Was to evaluate Diode laser for treatment of hemorrhoid.

MATERIAL AND METHODS:

This study included patients who suffer from the hemorrhoid. Cases with fistula and fissure had been omitted. Patients with hemorrhoid in grade 2, 3, 4 and mixed were treated with diode laser. Follow up was done 1,7,14, 30, 90, and 360 days laser therapy.

RESULTS:

In this study, 341 patients with hemorrhoid treated with diode laser were included. Results of follow-up were as follows: need for analgesia in hospital stay and home was very low total complication was seen in 12 patient (3.51%), edema in 8 patient (2.34%), hemorrhage and abscess each of them in 2 patient (0.58%), stricture and recurrence was zero after one year.

CONCLUSIONS:

All methods used for hemorrhoid treatment has advantages, disadvantages, and limitations. But treatment of hemorrhoid by Diodelaser, which is done by skilled surgeon has several advantages over other treatments. This advantages include, less operation time, less pain and bleeding, allow quick healing of piles, no stricture, and minimal recurrence after operation.

Laser proctology surgery

What are hemorrhoids and how often they are faced?
At birth everybody has a vascular plexus around the rectum, mostly consisting of veins. It has a specific function –  function of barrier. Often, during the lifetime, this vascular plexus is affected by various factors and as the result enlarges and begins to disturb. This situation is then known as hemorrhoids.
Up to 50% of all EU citizens are faced with problems or discomfort in this regard. Both men and women are struggling with hemorrhoids. The highest risk of experiencing the hemorrhoid problems is between 45 to 55 years, although in practice it's possible to see very young and very elderly patients with hemorrhoid problems.

How hemorrhoids let know about itslef?
Presentations are very different. Discomfort in the rectal area, itch, spotting (fresh) at the bowel, inflammations (painful formations in the rectal area), at the later stages nodes in the time of dejection or physical exertion.
Hemorrhoids don’t have specific symptoms. There may be similar symptoms in the cases of relatively harmless diseases (small rupture of the mucous coat, small polyp, etc.) or very serious diseases (cancer, rectal inflammations - ulcerative colitis and Crohn's disease), requiring immediate and serious treatment.

The hemorrhoid problems can be solved only surgically?
People often have the impression that the surgeon-proctologist should definitely operate every patient. There are cases, when it’s necessary, but there are also other methods of treatment. The main problem is to go to the proctologist, and then to continue the dialogue.

Is it necessary to prepare something specific for the visit to the proctologist?
The first visit does not require any specific preparation. Some people think that it’s forbidden to eat or drink during the whole day, or use any medicines for bowel cleansing  - it is not necessary. If a person subjectively feels that it will be better, he can make one microclyster with non-prescription medicines, bought in pharmacy, but this is not obligatory. If during the preparation for a specific procedure some additional actions will be necessary, the doctor will tell about them in details. No medicine,  prescription or non-prescription, should not be used unnecessarily. Patients of laser medical clinic patients are provided with the most discreet and delicate attitude and comfort, which are not less important.

Which technologies are used during surgery?
By using a laser, the haemorrhoids nourishing blood vessels are burned up. Studies have proved that in case of enlarged haemorrhoids, these blood vessels are badly enlarges, the circulation of blood is increased. This method is mostly being used at early stages of hemorrhoids, when the nodes in anal orifice are not observed, but the patient has more complaints directly on the bleeding.

With the use of  laser technology for more complex haemorrhoid problems, in the hemorrhoid node is sticked a “laser needle” and burning up is performed, leading to node flattening, so to say - stick to the gut wall. It’s very accurately estimated how much energy is needed for this purpose, in order to prevent affection of the sphincter or rectal mucosa. This can be local anesthesia, with the help of a special barrier, but there are situations, when the surgery requires anesthesia (usually spinal or intravenous anesthesia).
The pain is not very strong, but there is a physiological burn, certain discomfort and the anaesthetic pills should be used, but in terms of pain that is not comparable to the classical operation. In general, several hours should be spent in the clinic. If the patient lives far away, operation is scheduled for afternoon or the disease degree is high, we offer to stay in hospital for the night.

Treatment Parameters



It depends on the  spot size  so I will give you a few protocols 
600 micron fiber  one cm away from toe nail //// T on  3 ms  /////     T off  30 ms  ////  total joules 500 joules hallux toe nail ///  250 joules   less toes//// PEAK POWER 15 watts  

You may have to turn down the  PEAK POWER  to 10-15 watts if the  patients feel too much heat.  or you can  increase the T off  40,50 ms I prefer to  keep with 15 watts and adjust the T off to 40 ,50 ms
If you can't adapt to this protocol  Use  650 us Ton and 650 Toff  . Some doctor have power learning how to move the handpiece so we start with this protocol and with experience move to the  first protocol
Remember if its too hot  and it all depends on patient you stop place finger on toe nail and press will cool the  nail. Then adjust the  power and or the T0ff. I like to adjust the Toff instead of reducing the peak power down from 15 to 12 watts. Also this is at least  three treatments 30 days apart. This is a painting motion with the hand piece.
