Causes  of hemorrhoids prolapse

To the pathogenetic factor because the disease manifests itself, a series of predisposing or triggering factors must be added:

Constipation and socio-environmental, behavioral, individual, hormonal factors

1. Chronic constipation
2. Diarrhea
3. Low-fiber diet
4. Habit to pamping
5. Heavy work
6. Work that requires long periods in a sitting or standing position
7. Excessive sedentariness
8. Weight gain or obesity
9. Abuse of alcohol, tobacco, spices
10. Pregnancy
11. Cyclical hormonal influences in the female (acting on the tone of the venous walls)
12. Traumatizing sports (motorcycling, cycling, riding, weightlifting)


Hemorrhoidal anatomy

Anatomically we distinguish:
- internal hemorrhoids
- external hemorrhoids.

The internal hemorrhoids are borne by the upper hemorrhoidal plexus, are submucous, located across the anorectal line and up to the hairline, above the semilunar valves (and the Parks ligament); external hemorrhoids are on the lower hemorrhoidal plexus, are subcutaneous and are located below the comb line and semilunar valves (and Parks ligaments).

Clinical classifications of hemorrhoidal prolapse

The old classification is simply the punishment and prolapse of the anodermine with the breaking of the bonds of parks as a cause and the risk of haemorrhoidal prolapse as an effect.
Hemorrhoids are classified into four grades according to their size and their prolapse.
1st degree: haemorrhoids increased in size, due to congestion, only during defecation, internally, only visible with rectal examination or anoscopy; internal mucosal prolapse. In this case the symptoms may be missing, they are present, they are modest and precise of heaviness and annoyance in the anal region; sometimes itching; rarely and sporadically can be a slight bleeding at the end of defecation.

2nd degree: there is the progressive distension of the venous packets and the release of the submucosa with prolapse; the gremocci protrude during defecation, but are reduced spontaneously at the end of the same; external mucosal prolapse which can be reduced spontaneously. The symptomatology is present but of variable entity. Generally the symptoms are modest (tenor, tenority, persistent sense of weight and annoyance); more often the symptom is the bleeding that accompanies or follows the defecation and that can be of various entities: mostly it is modest and occasional; if chronic or intense it can lead to a framework of anemia; it can present itself as a real haemorrhage with consequent acute anemia. Compare initial sections of symptoms from ODS (obstructed defecation syndrome) that are represented by constipation or its appearance, if previously absent.


3rd degree: the size of the hemorrhoidal packets is always greater, the ligament of parks is more and more relaxed and released, exacerbating the mucous prolapse; the gremocci protrude outside during defecation and can be put back in place only manually; external mucosal prolapse manually reducible.

The symptomatology is accentuated; worsen the tenesmus, the itching, the sense of heaviness, can compare the lighter, more often stippling or burning; bleeding is present more frequently; the appearance of "dirt" is possible; the bleeding is almost constant. Compare or worsen if already present, including symptoms from ODS: constipation, fragmented defecation, incontinence in faeces.

4th degree: there is complete unraveling of the bonds of Parks with prolapsed muco-cutaneous prolapse and of the gavoccioli which become increasingly large; permanent external mucosal prolapse.

What are the signs and symptoms?

The symptoms are further aggravated; the pain is felt as puncture or burning or occurs with spasms, more frequently nocturnal; there is intense itching, tenesmus, a sense of tension due to edema and congestion, a sensation of a foreign body, constant "soiling" can cause irritation and maceration of perianal skin; the bleeding is almost constant. ODS symptoms are aggravated: constipation, fragmented defecation, stool incontinence, excessive and prolonged exacerbations, pain or rectal and perineal pain.

Morphological classification

To this traditional and dated classification, recently a new, morphological one has been added, which refers to the mucous prolapse:

TYPE 1: rectal mucous prolapse with anoderm in anatomical position
TYPE II: a) anoderm located in distal, soft and mobile position;

b) dislocated anoderm in distal, fibrotic and with plicomas (skin-tags)
This classification was also old compared to the new thrusts and the new studies of the pelvic floor pathology. In two important forums and in the presence of important international proctosurgery, we have come to a new and modern classification that brought together the pathology of the prolapse of the rectum and of the pelvic floor disorders in a complete and complete classification below:
