Systematic review of laparoscopic versus open surgery in the treatment of non-parasitic liver cysts.
We conducted a systematic review of the literature on the electronic databases Medline, Embase, Ovid and Cochrane to identify studies from 1990 to 2011 regarding the surgical management of non-parasitic liver cysts treated with laparoscopy (LT) and/or laparotomy (OT) to identify short-term and long-term outcomes of the relative treatments. Two reviewers independently extracted data regarding the following parameters: first author, year of publication, type of journal, study design, number of patients operated on, male/female ratio, mean age, mean size of the cysts treated, laparoscopic conversion rate, morbidity, mortality and recurrence in both groups (LT and OT). A qualitative analysis was carried out using the Pearson Chi square test and the Fischer's exact test where necessary. ⋯ The current data in the literature show that the laparoscopic approach may be the treatment of choice in patients with symptomatic non-parasitic cysts of the liver, providing the short-term advantages of minimally invasive surgery. Recurrence rates were acceptable and comparable to those of conventional surgery. Long-term outcomes should be verified by additional randomised controlled trials and long-term follow-ups.
