title: The Comparison of 2 New Promising Weapons for the Treatment of Hydatid Cyst Disease: PAIR and Laparoscopic Therapy.
abstract: BACKGROUND
  To compare the effectiveness and safety for hydatid disease treatment, the 2 new minimally invasive therapies: laparoscopic and PAIR (puncture, aspiration, injection, and reaspiration) were compared by systematic meta-analysis.
  
  
  METHODS
  A comprehensive analysis of published cases from 1990 to 2014 was performed using PubMed database. A total of 231 publications on laparoscopic treatment of hydatid cysts and 298 publications on the PAIR treatment were identified. Thirty-eight studies involved 1230 laparoscope-treated subjects and 41 involved 2686 PAIR-treated subjects in this review. The effectiveness and safety of emphasis is placed on the recurrence, insufficient response, death, cure, and postoperative complications. Operation time and hospital stay are also discussed as new evaluation index. The stages of cyst are summarized to determine which stage is suitable for PAIR.
  
  
  RESULTS
  Clinical and parasitological cure occurred in 98.7% of patients undergoing laparoscopic intervention and in 97.5% of patients receiving PAIR plus chemotherapy (P<0.014). Recurrence occurred in 1.0% and 1.6%, respectively (P<0.087). Insufficient response occurred in 0.16% and 0.9%, respectively (P<0.009); 2 patients died in each group (P<0.594). Allergic reaction/urticarial/anaphylactic shock occurs in 0.14% and 4.24% of patients receiving laparoscopic intervention and PAIR plus chemotherapy, respectively (P<0.001). Infection/abscess (5.37% and 2.57%; P<0.001) and surgical-related complications (7.32% and 3.43%; P<0.001) were seen more frequently in laparoscopic intervention subjects than PAIR plus chemotherapy subjects.
  
  
  CONCLUSIONS
  Laparoscopic therapy and PAIR intervention are shown to be safe and effective alternative for open surgery with suitable indication such as cyst type and location. They have different postoperative complication features. The biliary fistula/bile leakage was more frequent in laparoscopic intervention (P<0.001) and fever occurred more in PAIR plus chemotherapy patients.
