  Laparoscopic cystectomy is widely performed for dermoid cysts. However, the total laparoscopic approach is associated with greater risk of intraoperative spillage (IOS). Although a few cases of chemical peritonitis (CP) have been reported following IOS, the association remains unclear. We conducted a retrospective study of spillage of dermoid cysts during laparoscopic cystectomy in a single institution. A total of 141 patients who underwent laparoscopic cystectomy for dermoid cysts at our institution between 2012 and 2016 were identified. Eighty patients (57%) developed IOS, and had a significantly longer operative time (60.0±25.7 min vs. 47.9±11.9 min, p<0.01) compared with patients who did not develop IOS. We did not observe significant differences in cyst diameter (6.8±2.4 cm vs. 6.1±1.4 cm, p=0.06), or in the rate of postoperative fever between the groups. No patients developed CP. We concluded that controlled IOS was not associated with postoperative complications, although further investigation is needed.
