¹The main reasons for conversion to open surgery were bleeding and difficult location of the cyst;

²Wound infection, cyst rupture, anaphylactic reaction, hemorrhage, atelectasis, pneumonia and hernia. One patient died 1 mo postoperatively of candida sepsis in the Bickel et al[58] study and 1.16 % (2 patients) for open surgical procedure in the Zaharie et al[60] study. No postoperative mortality was observed in the others studies;

³Conversion the closed cavity of the cyst into an open pouch by incising it and suturing the edges of its wall to the edges of the wound;

⁴Laparoscopy approach.
