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.
Y. Ziv, 2008
Hemorrhoids
• Medical Treatment :
• Sitz baths,• Diet,• Hygiene,• Stool modifiers,• Topical creams, Suppositories.
Y. Ziv, 2008
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
Y. Ziv, 2008
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)
• Swelling
• Fever
Ano-rectal Pain & High Temp.
= Abscess, until proven otherwise !
Y. Ziv, 2008
Anal FistulaDiagnosis:• History & Physical Examination• Digital Examination• Ano/Rectoscopy• EUA• Fistulography• TRUS• CT-Fistulography• MRI (Ext., Coil)
Y. Ziv, 2008
Anal Fistula
• 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)
• Special Fistulas Recto - Vaginal Fistula,
Associated with Underlying Disease
(TB, IBD, Irradiation, Infections)
Y. Ziv, 2008
Anal Fistula
• Asymptomatic Fistulas
Require No Therapy !!!
• Medical Treatment May Cure Simple Mild Symptomatic Fistulas (sitz-baths, antibiotics)
Y. Ziv, 2008
Anal Fistula• Surgical Treatment :
Fistulotomy or FistulectomyFibrin GlueAnal PlageSeton Placement (Loose, Tight)RAF (Mucosal or Full Thickness)ColostomyAnterior resectionPatches (Omentum, Muscles)

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–

של ODSאבחנה
השבועות האחרונים 12הופעה קבועה ביותר מרבע היציאות ב-של:
מאמץ מוגבר ביותר ביציאה–צואה קשה וגושית–הרגשה של חוסר התרוקנות–הרגשה של הפרעה או חסימה ביציאה– שימוש ביד לצורך יציאה- לחץ וגינאלי, רקטלי, לחץ על –
חיץ הנקביםפחות משלוש יציאות לשבוע–

הקליני הברור
לפני הניתוח על החולה לעבור סדרה של בדיקות אשר יגדירו האם הוא מתאים ליפול שמרני או
ניתוח
דפקוגרפיה•
מנומטריה •
אלקטרומיוגרפיה EMGבדיקת •
TTIבדיקת זמן מעבר •
TRUSבדיקת •
