WATER LILY

SIGN

WATER LILY SIGN

• Detachment of the Endocyst membrane which results in floating membranes within the Pericyst that mimic the appearance of a water lily.

• Chest X-ray, US, CT or MRI.

• Transitional stage between active and inactive disease.

• Decreased intra-cystic pressure, degeneration, host response, trauma or following therapy.

HYDATID CYST

OPERATION EXCISION HYDATID CYST LIVERJuly 2017

• INCISION: Through scar previous Kocher incision

• FINDINGS:

1) Frozen abdomen! Extensive Adhesions.

2) Main large HC at the dome of the right lobe liver under the diaphragm

3) Small (incidental) HC near gall bladder fossa. (Likely the same HC encountered in previous cholecystectomy).


15

OPERATIVE FINDINGS:


16

The smaller HC at Gall

Bladder fossa

DR. M. AL-GAILANI FRCS, AHH SUWAIDI

OPERATIVE PROCEDURE:

1. Packing all around HC.

2. Hypertonic Saline intra cystic injection.

3. Complete evacuation all endocyst and daughter cysts of both HCs avoiding any spillage.

4. Two corrugated drains: sub hepatic & intra cavity of the larger HC.

FOLLOW UP

• Histology & Microbiology:

HC confirmed: HC wall enucleation, outer ectocyst, inner endocyst, germinal layer & daughter cysts.

• Uneventful postoperative recovery

• Drains removed 12th postoperative day

• Discharged well.

EPIDEMIOLOGY OF HC:


21

1. Human Hydatid Cyst is

prevalent in the Middle

East and North Africa.

2. Hyper endemic in Turkey,

Iraq, Jordan, Morocco,

Libya & Algeria.

3. Hydatid cysts are found in

Sheep, Goats, Cattle &

Camels.

4. Sheep-Dog spread is the

most important Zoonotic

transmission vehicle for

Human Hydatic Cyst

disease.

• Cystic Teratoma


• Cysticercosis

• Hepatic Cysts

• Liver Abscess

• Primary Hepatic Carcinoma

• Casoni Test: intradermal skin test Sensitivity 70%

• Plain X-ray: A thin rim of calcification delineating a cyst is suggestive

• US: Cyst Wall, Daughter Cysts, Water Lily Sign

• CT

• MRI


32

MANAGEMENT:

1. SURGERY: Remains the primary treatment and the only hope for complete cure.

2. MEDICAL:

Inoperable because of location or multiple organs

Unfit for General Anaesthesia

Disseminated Peritoneal disease.

a. Albendazole (10-15 mg/kg/day) orally for 3-6 months

b. Mebendazole (40-50 mg/kg/day) orally for 3-6 months


33

SURGICAL TECHNIQUE:

1. Isolation: surrounding tissues are protected by covering them with cetrimide-soaked pads

2. Intra Cystic Injection Scolicidal Agents: Hypertonic saline 20%, Chlorhexidine 10%, Absolute alcohol 95%, Hydrogen Peroxide 3% or Cetrimide 1.5%.

3. Cyst aspiration and evacuation: Spillage Free

4. Remaining cavity:

1) Close after closure of any biliary communications

2) Omental packing

3) Marsupialization

4) Drainage


34

PUBLIC HEALTH & PREVENTION:

• Breaking down the life cycle by stray dog control

• Preventing sheep offal from being fed to stray dogs

• Thorough washing of all vegetables especially lettuce with soap and running water

• Soaking of vegetables in Potasium Permangate or any other antiseptic is ineffective!
