title: Mechanical suction through wide bore catheters for nonsurgical management of Gharbi type III hepatic hydatid cysts.
abstract: OBJECTIVE
  To present our experience with management of complex hepatic hydatid cysts (Gharbi type III), using percutaneous large bore catheter drainage followed by active mechanical suction of cyst contents.
  
  
  METHODS
  Eleven patients (6 males and 5 females with a mean age of 43.2 years), with 13 complex Gharbi type III hepatic hydatid cysts were included in the study. Under sonography guidance the complex heterogeneous hepatic hydatid cysts were treated percutaneously using large bore drainage catheter and active mechanical suction.
  
  
  RESULTS
  Successful drainage of all 13 complex Gharbi type III hepatic hydatid cysts was achieved in all patients (n = 11). The mean duration of catheter placement was 11.3 days (range 7 to 40 days). The most common problem encountered was biliary fistula (n = 3), which was effectively managed with prolonged catheter drainage and/or endoscopic intervention. No serious complications or deaths were encountered. Minor complications were seen in 7 patients including, urticaria in 3, fever in 2 and reactive pleural effusion in 3. All patients responded to symptomatic treatment. Follow up serial ultrasound was performed on all patients, that showed near complete healing in 9 and formation ofpseudotumour in 4 patients. There was no recurrence with a mean follow up of 15.23 months (6 months - 2 years).
  
  
  CONCLUSIONS
  Percutaneous suction and large bore catheter drainage of Gharbi type III hepatic hydatid cysts is a safe and effective alternative therapy.
