WHAT ARE HAEMORRHOIDS?
They are vascular cushions, composed mainly of venous blood. Their purpose is:

  1. Accompany faeces to the outside reducing anal trauma
  2. Complete the complex system of faecal continence.

Only when symptoms are present, they can be defined as a haemorrhoidal disease.
They are the most common cause of pain in the anorectal region.
More than 50% of the adult population of the western world suffers or has suffered from them.
Many people neglect symptoms for a long time before seeking medical help.
Current forms of treatment are able to eliminate the problem with little or no pain, especially in the early stages.

WHAT IS HAEMORRHOIDAL DISEASE?
They are erroneously described as “varicose of the anus”. Pathological haemorrhoids are cavern like corpses, increased in volume, with contain blood of the veins and of the arteries, and can protrude from the anus. Depending on the plexus where they have origin, they can be divided into internal and external.
Internal haemorrhoids increase their  volume inside the anus  and  one becomes aware of them only during the passage of faeces because of pain, bleeding and  rash, they can prolapsed  towards the outside of the anus ad return inside spontaneously or with manual  help. They become painful if they can’t be placed back into position.
External haemorrhoids develop at the margin of the anus, if under tension they become painful; they become more complicated than internal haemorrhoids due to the formation of internal clot (haemorrhoidal thrombosis).

WHAT CAUSES HAEMORRHOIDS?
It is a multifactorial disease and there isn’t one only cause. Haemorrhoids disease develops more with: the increase in age, excessive straining during evacuation, long periods of time on the toilet, very hard or irritating stools such as in diarrhea, pregnancy and hereditary factors, hygienic-behaviours such as a low-fibre diet, low intake of fluids, sedentary life style.

WHAT ARE THE SYMPTOMS OF HAEMORRHOIDS?
As already mentioned, if any of the following symptoms are present, it is possible to speak of haemorrhoidal pathology:
1.    Bleeding during the passage of stools or on toilet paper or in the cup of water at the end of       defecation. (sparkling fresh red blood).
2.    Prolapsed that can re-enter more or less easily.
3.    Itching often accompanied by the feeling of humidity (in the anus).
4.    Pain, generally as a burning sensation.
5.    External painful lumps, at times they develop within a few hours.

IS THERE ANY CORRELATION WITH CANCER?
There is no correlation. However many of these symptoms can be present even when there is a rectal cancer. This makes it necessary to undergo  a proctologic check-up, even type of treatment which is given without specialist indications, can cause an unacceptable delay in a correct diagnosis and in prescribing adequate treatment.

WHAT FORMS OF TREATMENT ARE THERE?
Medical treatment must be aimed at the possible cause:
  1. If constipation: increase in vegetable fibre and use of laxatives forming a mass that gives
      softer stools.
  1. Correction of diarrhea, if present.
  2. Regaining the habit of a correct passage of stools (avoiding pushing too much and for too
long).
  1. Bidet with warm water to reduce spasm and pain.
  2. Flavonoids.
  3. Correction of diet, intake of fluids, avoids irritating foods and alcohol.

In case of severe attacks, mostly due to haemorrhoidal thrombosis, these aids can be useful, in
combination with analgesics and within about seven days the attack clears up. If the pain persists,
the doctor in charge carries out a small incision, under local anaesthetic in order to remove the clot/s.
If the case is of a more serious nature and is a thrombosis, treatment in hospital may be necessary.
Treatment can be given as an outpatient or in hospital depending on the stage of the disorder and
on its clinical importance.

Of course, after accurate proctologic examination, exploration, proctoscopy (and eventually a colonoscopy) and a classification of the severity of haemorrhoidal disease can undergo therapy.
Medical treatment should be given to patients with piles of 1st and 2nd degree without complication and is based on the use of different substances. Initially, if necessary, we must encourage evacuation daily and "soft" to avoid the effort and are useful for this purpose all those substances which increase faecal bulk and are not irritants. We must promote increased circulation to the haemorrhoidal venous return with preparations of flavonoids and the like. Finally you can use to relieve symptoms, creams, and pastes, gels containing anti-inflammatory, anaesthetics and lately hyaluronic acid.
In some cases, resistant to medical treatment, can be implemented local treatments, para-surgical therapies such as rubber band ligation used in treating haemorrhoids and for internal rectal prolapsed mucosa. It consists in the application of small elastic rings at the basis of the haemorrhoids or prolapsed; this is carried out without any anaesthetic. This procedure does
not generally cause pain although in the hours that follow the procedure there could be a
bothersome heavy feeling. The small elastic rings remain in place between 7 and 15 days
and generally their expulsion is not felt except for a slight loss of blood that should not
frighten the patient. Only in exceptional cases there is a haemorrhage, and it is necessary
to go to emergency or to contact one’s own doctor or specialist.
Sclerotherapy and infrared coagulation are only used in the treatment of general
haemorrhoids and not for prolapsing ones. Such procedures cause only slight pain and the
result is a discrete reduction in volume of the haemorrhoids.
Patient’s refractory to these therapies, in cases where it has been impossible to obtain a satisfactory result and haemorrhoids of 3rd and 4 degree with skin tags are candidates for surgery.
Typically require a brief hospitalization (or often outpatient day-surgery) and are made under anaesthesia. There are several protocols for the control of postoperative pain and discomfort.
So the surgical intervention in haemorrhoidal disease is indicate in:
  1. The haemorrhoids of 2nd and 3 rd degree and refractory to medical para-surgical therapy.
  2. In haemorrhoids 4 degree.
  3. In cases of haemorrhoids recurrence.
  4. In cases associated with occult rectal mucosal prolapsed.
  5. In cases associated with anal fissure.
The ideal intervention should meet several requirements:  NO PAIN, NO COMPLICATIONS AND minimum hospital stays with an early return to work.
Techniques that use laser scalpel do not give a reduction in pain compared to the more traditional. The use of new tools for radiofrequency coagulation (LigaSure®) and ultrasound can reduces post-operative pain.
A
bove mentioned techniques, or in cases that have not reached satisfactory results, there
are many techniques that have in common the removal of haemorrhoids. They require a
short stay in hospital and are performed under anaesthesia. There are different protocols
that control the discomfort and post-operational pain. Techniques that make use of laser
scalpel do not reduce the amount of pain, compared to traditional scalpel.
A new technique foresees the use of circular stitches.
Mucoprolassectomy with mechanical (circular) stapler is used, with sufficient consensus in literature, for haemorrhoids of 3rd degree, while for other grades there is still a lot of discussion among experts.
Mucoprolassectomy is carried out in hospital with spinal anaesthesia. The short term
results are good but relapses are frequent. Complications are rare, sometimes persistent
and difficult to treat.
The ligation of the terminal superior haemorrhoidal artery identified by a post-surgery
doppler system and followed by haemorrhoidal surgery is a new technique. It is mainly
performed on haemorrhoids of 3rd degree even if scientifically studies have described this
technique in haemorrhoids of different grades. The procedure is performed in day surgery,
under local or spinal anaesthesia.
80% of patients do not require analgesics following the procedure, and the complications
are minimum in severity and duration of time. Only a very small percentage of
patients requires a new procedure due to relapse.
The ligation of the superior haemorrhoidal artery terminal branches identified with the intraoperative use of a Doppler system and the hemorrhoidopexy (THD®) is carried out mainly in haemorrhoids of 3rd degree, although scientific studies have described this technique for others. The treatment is performed as an outpatient, under local anaesthesia with sedation or spinal anaesthesia, and 80% of patients did not need analgesics after surgery, and complications are minimal in the reported number, severity and duration; only a small percentage of patients need new treatments for relapse. The surgery is performed in an area devoid of nerve endings and thus has little or no pain. It is a minimally invasive intervention.
Cryotherapy, in radical treatment, is painful in comparison to other forms of outpatient treatment has a higher risk of recurrence.  Other techniques such as direct fulguration and BICAP are not a preferable form of treatment in major international centres of proctology.
Therefore, as a guideline for the treatment of haemorrhoidal disease we can say that  haemorrhoids grade 1 and 2 symptomatic, first is important to performed medical nutrition therapy, if no improvement of symptoms them we proceed with the para-surgical techniques (rubber band ligation, sclerotherapy, photocoagulation).
In the third degree and degrees in the failure of previous surgery we will can use: THD®, prolassectomia with stapler if there is in association with mucosal prolapsed.
In the fourth degree with big skin tags: haemorrhoidectomy (LigaSure®, Ultracision®, Milligan-Morgan or THD® with removal of the skin tags.
