Proctitis - an inflammation in or on anus which a painful inflammation of the tissue around the rectum that can occur in cute or chronic factor.
Its etiology can be stds, autoimmune disease,harmful physical agents.symptoms are pain,fever,chills, malaise,skin irritation,discharge of pus, constipation
CHRONIC PARAPROCTITISManifested festeringfistula
• Mouth of fistulous passage[ depends on
tract’s path]: near the anus; on the
buttock.
• Pain is usually not expressed- unlike in
acute
• Pus – frequently flushes out of fistula
• Presence of feces indicates connection to
rectum’s lumen
Factor contributing to chronic nature
1. Persistent infection source
2. Fistula tract characteristics
[epithialization,granulation]
3. Reactivation of dormant infection
7.
Diagnosis
• Complains- painin area of rectum and anus – can go with basic anal check up
Ultrasound examination
using rectal sensor
Fistulography

OPERATIVE TREATMENT
Surgical treatmentof acute paraproctitis includes early emergency surgical intervention
by opening the abscess with removal of pus and necrotic tissues, examination of the
abscess cavity with a finger, separation of the bridges and drainage of the cavity.

Approaches to radicalsurgery
1. Opening > Drainage > cyst excision > FISTULA DISSECTION
Fistulous tract is dissected and separated from surrounding tissue and opened into lumen of
rectum ensuring complete drainage and removal of infected tissue.
2. Opening > Drainage > Crypt excision > SPHINCTEROTOMY
A portion of anal sphincter muscle is cut. This approach is used when fistula tract runs through
the anal sphincter muscle.
3. Dissection > drainage > crypt excision > LIGATION
The fistulatous tract is tied off using suture. The aim is to interrupt the connection between
the infected area and rectum . It is less common method for acute infections.
4. Dissection > Drainage > DELAYED CRYPT EXCISION > GUT FLAP MOVEMENT
Abcess opened an drained. The removal of crypt is delayed until acute inflammation subsides.
A flap of rectal tissue is moved to cover the opening and interrupt the communication btw
rectum and infected area. This breaks the pathway for further infection and help to heal.
Mostly used in severe cases.

• In orderto help the examiner predict the trajectory of the
tract and probable location of the internal opening, Goodsall's
Rule can be applied.
• With the patient in the lithotomy position :If the external
opening is anterior to an imaginary line drawn-across the
midpoint of the anus, the fistula runs straightly into the anal
canal.
• If the external opening is situated posterior to the line, the
track usually will curve and the internal opening will be on the
midline posterior of the anal canal.
• An exception to this rule is when the external opening is
anterior to this imaginary line but is situated more than 1½
inches away from the anus. In this case the track will curve
posteriorly and end in posterior midline.

INCISION
APPLY SEMILUNAR AND
RADIALINCISIONS [ they
provide gapping wound
which helps the purulent
outflow]
1. For perineal abscess
2. Behind mousse
3. Ischiorectal
Surgical approch for [1] ischiorectal
[2] pelviorectal abcesses

DISSECTION – Insubcutaneous paraproctitis
Incision in-
radial direction
Retrorectal incision
TREATMENT
• ANTIBIOTICS s/aDoxycycline[oracea, vibramycin]
• ANTIVIRAL drugs s/a acyclovir[zovirax]
• Treatment to destroy damaged tissue – by this technique
ablation which is bleeding can be removed
• Medications in form of suppository, enema which helps in
reducing inflammation and reduce bleeding.
• Surgery

COMPLICATIONS
• Purulent Fusionof the Rectum Wall with Spread of
Intestinal Contents: This is the primary initiating
event. The infection erodes the rectal wall.
• Formation of a Purulent Fistula Between the
Rectum and Vagina:
• Purulent Melting of the Urethra and Spread to the
Scrotum:
• Breakdown of Pus into the Abdominal Cavity and
Retroperitoneal Tissue: The most life-threatening
complication is the spread of the infection into the
free abdominal cavity.
* Peritonitis; Retroperitoneal
Phlegmon ;Sepsis;Death
• Necrosis of the Skin: The skin overlying the abscess
can undergo necrosis (tissue death) due to the
pressure and destructive effects of the infection.
