Background:
Laparoscopic deroofing has been shown to produce good patient satisfaction and to have results similar to those of open surgical techniques. We evaluated the feasibility and efficacy of laparoscopic deroofing using an argon beam coagulator (ABC) in the patients with nonparasitic liver cysts.
Methods:
Laparoscopic deroofing for the treatment of liver cysts was attempted on 14 patients. After the deroofing, the secreting epithelium within the residual cystic cavity wall was destroyed using the ABC.
Results:
Laparoscopic deroofing was successful in all patients. No deaths or surgical morbidity occurred, and no postoperative complications were recorded. The median postoperative hospital stay was 7 days. The median follow-up was 56 months for all patients, and all patients have remained completely asymptomatic for 6 months after the surgery, with no recurrence of the cysts.
Conclusions:
Our results indicate that laparoscopic deroofing using the ABC method in patients with nonparasitic liver cysts was effective in preventing cyst recurrence.
