Study of treatment results and early complications of tube drainage versus capitonnage after the unroofing and aspiration of hydatid cysts

SummaryObjectiveThere is controversy concerning the management of the remaining cavity after the evacuation of a cyst in patients who have undergone surgical operation for liver hydatidosis. This study compares the results of capitonnage and tube drainage of the remaining cavity.MethodsIn this retrospective study, participants were selected from two groups of patients with a liver hydatid cyst who underwent capitonnage or tube drainage from 2004 to 2012. The patients were followed for 6–24 months. The data of age, sex, involved liver lobe, size of the cyst, complications, drain duration, and hospital stay were analyzed.ResultsParticipants included 155 patients consisting of 96 (61.94%) females and 59 (38.06%) males. Most cysts were in the right lobe, and the most common diameter of the cysts was greater than 10 cm. Capitonnage was performed on 90 (58.06%) patients and the tube drainage procedure was performed on the remaining 65 (41.94%) patients. In the tube drainage group and the capitonnage group, the operative times were 2.21 ± 0.65 hours and 2.53 ± 0.35 hours, respectively; the hospital stays were 5.695 ± 3.37 days and 4.43 ± 2.96 days, respectively; the drain duration was 9.2 ± 1.7 days and 2.1 ± 0.4 days, respectively; and the time to return to work was 14.7 ± 2.3 days and 8.3 ± 10.4 days, respectively. All variables were statistically significant, except for the operative time. Cavity infection and biliary fistula were identified in three patients and six patients, respectively, in the tube drainage group and identified in two patients and three patients, respectively, in the capitonnage group. This difference was not statistically significant.ConclusionThis study demonstrated that capitonnage versus the tube drainage method may result in a shorter hospital stay, decreased time to return to work, and low rate of morbidity and complications.
