DefinitionA break in the epithelial continuity
Discontinuity of the skin or mucous membrane which occurs due to the microscopic death of the tissues

Wagner’s Grading of ulcers
Grade 0 - Preulcerative lesion/healed ulcerGrade 1 - Superficial ulcerGrade 2 - Ulcer deeper to Subcutaneous tissue
exposing soft tissue or boneGrade 3 - Abscess formation or osteomyelitisGrade 4 - Gangrene of part of tissues/limb/footGrade 5 - Gangrene of entire one area/foot

EDGE
Induration (hardness) of the edge is very char acteristic of squamous cell carcinoma.
It is said to be a host defense mechanism.
Tenderness of the edge is characteristic of infected ulcers and arterial ulcers.
![Page 36: Ulcer sinus fistula](https://reader037.fdocuments.in/reader037/viewer/2022102323/58f9b25c760da3da068bca71/html5/thumbnails/36.jpg)
BASEIt is the area on which ulcer rests.
Marked induration at the base is diagnostic of squamous cell carcinoma.
![Page 37: Ulcer sinus fistula](https://reader037.fdocuments.in/reader037/viewer/2022102323/58f9b25c760da3da068bca71/html5/thumbnails/37.jpg)
INDURATION
• The edge, base and the surrounding area should be examined for induration.
Maximum induration Squamous cell carcinoma
Minimal induration Malignant melanoma.
Brawny induration Abscess.
Cyanotic induration Chronic venous congestion as in varicose ulcer.
![Page 38: Ulcer sinus fistula](https://reader037.fdocuments.in/reader037/viewer/2022102323/58f9b25c760da3da068bca71/html5/thumbnails/38.jpg)
MOBILITY
Gentle attempt is made to move the ulcer to know its fixity to the underlying tissues.
Malignant ulcers are usually fixed, benign ulcers are not.
![Page 39: Ulcer sinus fistula](https://reader037.fdocuments.in/reader037/viewer/2022102323/58f9b25c760da3da068bca71/html5/thumbnails/39.jpg)
BLEEDING
Malignant ulcer is friable like a cauliflower. On gentle palpation, it bleeds.
Granulation tissue as in a healing ulcer also causes bleeding.
![Page 40: Ulcer sinus fistula](https://reader037.fdocuments.in/reader037/viewer/2022102323/58f9b25c760da3da068bca71/html5/thumbnails/40.jpg)
SURROUNDING AREAThickening and induration is found
in squamous cell carcinoma.
Tenderness and pitting on pressure indicates spreading inflammation surround ing the ulcer.

TREATMENT OF SPREADING ULCERSPus Culture/Sensitivity report, Appropriate Antibiotics Solutions to treat the Slough : H₂O₂ & EUSOL -
Edinburgh University Solution (Hypochlorite solution)
Excessive Granulation Tissue (Proud Flesh) : Excision or Application of Copper Sulphate or Silver Nitrate
Repeated Dressings,
![Page 47: Ulcer sinus fistula](https://reader037.fdocuments.in/reader037/viewer/2022102323/58f9b25c760da3da068bca71/html5/thumbnails/47.jpg)
TREATMENT OF HEALING ULCERRegular dressings are done for a few daysAntiseptic creams like Liquid Iodine, Zinc Oxide
or Silver Sulphadiazine.Culture swab is taken to rule out Streptococcus
Haemolyticus ( contraindication for skin grafting )Ulcer is small - Heals by itself ( Epithelialization )
Large - Free Split Skin Graft applied
![Page 48: Ulcer sinus fistula](https://reader037.fdocuments.in/reader037/viewer/2022102323/58f9b25c760da3da068bca71/html5/thumbnails/48.jpg)
TREATMENT OF CHRONIC ULCERS These do not respond to conventional methods of
treatment. The following are tried: Infrared radiation, short-wave therapy, ultraviolet rays
decrease the size of the ulcer. Amnion helps in epithelialization. Chorion helps in granulation tissue. These ulcers ultimately may require skin grafting.

FISTULOGRAPHY/ SINUSOGRAPHY:
• For knowing the exact extent/origin of sinus (or)fistula.
• Water soluble or ultrafluid lipoidal iodine dye is used.
• Lipoidal iodine is poppy seed oil containing 40% iodine.

TUBERCULAR SINUS OF NECK
Causative organism: mostly M.tuberculosis but also M.bovisSite and mode of infection: a) lymph nodes in anterior triangle from tonsils. b) lymph nodes in posterior triangle from adenoids. c) supraclavicular nodes from apex of the lung.

Stage of cold abscess: due to caseating necrosis.
non-tender, cystic, fluctuant swelling not adherent to overlying skin. Sternocleidomastoid contraction test- present deep to deep fascia trans illumination negative

solution with closure of wound without placing a drain.
ATT NOTE: I&D not done-persistent TB sinus.

CLINICAL ASSESMENT
HISTORY: full medical history incl. obstetric,anal, gastrointestinal, surgical, continence DRE: area of induration, fibrous tract and internal opening may be felt (“button-hole” defect in Ca rectum) PROCTOSIGMOIDOSCOPY: To evaluate rectal mucosa for any underlying disease process.

GOODSALL’S RULE• If external opening in anterior half of
anus, fistula usually runs directly into anal canal.
• If external opening in posterior half of anus, fistula usually curves midline of the anal canal posteriorly.

FISTULOTOMY In inter-sphincteric and low trans-
sphincteric fistulas. Identification of tract with probe followed by
division of all structures between external and internal openings.
Secondary tracts laid open. +/- marsupialization.
![Page 101: Ulcer sinus fistula](https://reader037.fdocuments.in/reader037/viewer/2022102323/58f9b25c760da3da068bca71/html5/thumbnails/101.jpg)
Advantages least chance of recurrence
relatively easy procedure minor degree of incontinence.
Risks results in large and deep wounds that might take months to heal.

FISTULECTOMY• All chronic (low) and also for posterior horse-
shoe shaped fistulas.• Excision of entire fibrous tissue and tract
and wound kept open.• Sphincter repair +/- advancement flap.• High anal fistulas +/-colostomy.

SETON SUTURE PLACEMENT• Preferable surgical option for high variety.• Setons are usually made from rubber slings• 2 types of seton suture can be placed• Draining Seton
Facilitates draining of sepsis Left loose and allows fistula to heal by fibrosis
• Cutting Seto Slowly "cheese-wires" though the sphincter muscle
Allows fibrosis to take place behind as it gradually cuts through

FIBRIN GLUE
Multi component system containing mainly human plasma fibrinogen and thrombin.
Injected into fistula track which hardens in few minutes and fills the track.
![Page 106: Ulcer sinus fistula](https://reader037.fdocuments.in/reader037/viewer/2022102323/58f9b25c760da3da068bca71/html5/thumbnails/106.jpg)
ANAL FISTULA PLUG The Anal fistula plug is a minimally
invasive and sphincter-preserving alternative to traditional fistula surgery.
The plug is a conical device and is placed by drawing it through the fistula tract and suturing it in place.
the plug, once implanted, incorporates naturally over time into the human tissue (human cells and tissues will 'grow' into the plug), thus facilitating the closure of the fistula.
