Hemorrhoids

Y. Ziv, 2008

Hemorrhoids

• Normal components (sub-mucosal vascular tissue) of human anatomy

• External (Inf. Hem. Plexus, Somatic Nerve)

• Internal (Sup. Hem. Plexus, Above DL, Senseless)

• Mixed

• 2 – Right Side, Anterior & Posterior• 1 – Left Side• M = F, Peak = 45-65y

Y. Ziv, 2008

Hemorrhoids

• Pathogenesis : - Increased age

- Ch. diarrhea or constipation

- Increased Intra - Abdominal Pressure

(prolonged sitting, pregnancy etc.)

• Hypothesis: Hypertrophy or

Increased Muscle Tone

Y. Ziv, 2008

Hemorrhoids

• Internal Hem. Classification• 1st deg : project into lumen & bleed.

• 2nd deg : protrude – spont. reduction

• 3rd deg : protrude – manual reduction

• 4th deg : irreducibly prolapsed.

Y. Ziv, 2008

Hemorrhoids

• Diagnosis• Medical History

• Physical Examination

Inspection

Digital Exam.

Rectoscopy

Y. Ziv, 2008

Hemorrhoids

• Symptoms :

– Ext, Hem.• Pain, bleed, swelling

– Int, Hem.• Bleed, swelling, soilage, itching, pain, discharge, protrusion.

• Medical Treatment :

• Sitz baths,• Diet,• Hygiene,• Stool modifiers,• Topical creams, Suppositories.

Hemorrhoids

• Minimally Invasive Treatment :• Int, Hemorrhoids (Grade 2-3)

• RBL

• IRC

• Sclerotherapy

• Cryo

Y. Ziv, 2008

Hemorrhoids

• Surgical Treatment :

• Ext, Hem.• Thrombectomy (Emergency)• Excision (Failed Med. Treat.)

• Int, Hem.• Excision or Resection with Anopexy or DHL

(Failed Med. or Invasive Treat. 4th degree, Association with other anal disease)

Y. Ziv, 2008

HemorrhoidsSurgical Treatment :

• Anal Dilatation (rarely used)

• Excision:- Open (Milligen-Morgan)

- Closed (Fergusson)- Semiclosed

• Resection with Anopexy (Longo Proc.)

• Trans Anal Ligation of Hem. Arteries

Y. Ziv, 2008

Hemorrhoids• Surgical Options :

• Scissors & Scalp

• Ligasure

• Harmonic Scalpel

• Laser

• Stapler

• DHL

Hemorrhoids

• Surgical Treatment :•Complications :

– Incontinence, Stenosis,

– Bleeding, Urinary Retention

– Infection (absc., fistula) > Sepsis

– Persistent Hemorrhoids

Y. Ziv, 2008

Hemorrhoids

• Incarcerated Hemorrhoids

• Treat Medically !!!

(Rest, Magnesium Sulphate 30%,

Suppsitories, Stool-softeners)

Avoids Complications Rate

Y. Ziv, 2008

Hemorrhoids

Hemorrhoids in Pregnancy• Treat Medically or Minimally Invasive

• Failure

Surgery

Y. Ziv, 2008

Anal Fissure

• Vertical tear in squamous epihelial lining of the anal canal between the anal verge and the dentate line

• Location :

Post – 85%, Ant - 10%, Lat – 5%

Y. Ziv, 2008

Anal Fissure

• Acute – No secondary changes

• Chronic– > 30d

– Symptoms > 50%

– Secondary changes

Y. Ziv, 2008

Anal Fissure

• Secondary changes:– Sentinel tag (sometimes w fistula)

– Hypertrophied anal papilla

– Indurated edges

– Exposed Int. Sphincter fibers

Y. Ziv, 2008

Anal Fissure

• Etioligy :- Trauma

- Spec. underlying Disease :

Chlamidia, Gonorrhea, Herpes, Syphillis, Aids, TB, Neoplasia, Crohn, Ulcerative Colitis.

Y. Ziv, 2008

Anal Fissure

• Pathogenesis :- Repeated trauma- Raised Mean Rest. Pressure- Spasm, ischemia “Stress fractures of the anal canal“- Underlying disease

Y. Ziv, 2008

Anal Fissure

• Symptoms :– Pain, bleeding, discharge,

swelling, itching.

Diagnosis :- Inspection, palpation- Anoscopy/rectoscopy (not recom.)

Y. Ziv, 2008

Anal Fissure

• Treatment• Acute AF

– Medical : Diet, Bulk laxatives,

Sitz baths, Topical creams.

• Chronic AF– Medical, Surgery

Y. Ziv, 2008

Anal Fissure

• Medical Treat. of Chronic AF- Diet, Bulk lax., Sitz baths, Creams.

“Chemical” Sphincterotomy- NTG, ISDN - NO transmitor- Nifedipine - Ca Channel Blocker- Botolinum A - ACE Inhibitor- Alpha-1 adrenoceptor blockade

Y. Ziv, 2008

Anal Fissure

• Surgical Treat. of Ch AF

- Open / Closed LIS

- Anal Dilatation (only in special cases)

- Fissurectomy

- Advancement Flap (from inside or outside)

Y. Ziv, 2008

Anal Fissure

• Surgical Treat. of Recurrent Ch AF

- Open / Closed LIS (other side, after TRUS)

- Anal Dilatation (only in special cases)

- Fissurectomy

- Advancement Flap (from inside or outside)

Y. Ziv, 2008

Anal Fissure

• Complications– Incontinence Conservative, Surgery

– Stenosis Dilatation, Surgery

– Hemorrhage Hemostasis

– Infection, Ab, Drainage – Urin. Reten. Cateterization

Y. Ziv, 2008

Anal Fistula

Pathogenesis :• Infected Anal Glands

(open to Dentate Line)

• Ductal Obstruction lead to ;

Stasis, Infection, Abscess.

50% develop Fistula

Y. Ziv, 2008

Anal Fistula

Signs & Symptoms :• Pain, Pruritus, Bleeding, Discharge.

• Pressure (evacution, cough, sitting)

• Park’s Classification:– Trans - Sphincteric

– Inter - Sphincteric

– Supra - Sphincteric

– Extra - Sphincteric

Y. Ziv, 2008

Anal Fistula

• Other Classification:– Simple Vs Compound (horseshoe)– Low, Middle, High (Anal Canal)– Small, Large (Int. opening)

ODSObstructive Defacation Syndroms

מצב שבו החולה אינו מסוגל להתרוקן באופן רגיל ונאלץלהשתמש במשלשלים, חוקנים או אמצעים אחרים.

כאבים בזמן יציאה–צורך במאמץ חריג על מנת להתרוקן–ישיבה ממושכת בשירותים– ימים5-10מרווחים ארוכים בין היציאות –אי נוחות באזור חייץ הנקבים בזמן עמידה– =Tenesmusתחושה מתמדת של חוסר התרוקנות – =Incomplete Evac התרוקנות לא רציפה –Incontinence = הפרעות בשליטה–
