The role of laparoscopic ultrasound in the minimally invasive management of symptomatic hepatic cysts

Background: Now; that the laparoscopic treatment of symptomatic liver cysti c disease has proven feasible and safe! it is gaining wide acceptance. Howe ver, due to diagnostic pitfalls and a relatively high recurrence rate, furt her improvements and refinement of the procedure are still needed. We have evaluated the contribution of laparoscopic ultrasound in the diagnosis and management of patients with symptomatic Liver cysts, Methods: Twelve patients with single or multiple cysts of the liver and two patients with polycystic liver disease were managed laparoscopically. Lapa roscopic ultrasound served as an integral part of the procedure in all pati ents, Results: Patients underwent either complete cyst excision (two cases) or re section of the extrahepatic cystic component (eight cases), Additionally, i n two patients, deep cysts not demonstrated by preoperative imaging studies were detected and treated with a combination of larparoscopy and laparosco pic ultrasound. In one patient with a cystobiliary fistula, conversion to a n open cystjejunostomy was necessary. Patients with polycystic liver diseas e underwent a combination of excision and unroofing of both superficial and deeper cysts using laparoscopic contact ultrasound throughout the procedur e, Laparoscopic ultrasonography was found to have a significant impact an t he operative strategy in five patients (36%) with multiple cysts or polycys tic disease. The postoperative course was uneventful in all cases. Thirteen patients remained asymptomatic throughout the follow-up period of 30 month s: one patient with polycystic liver disease developed recurrent symptoms a fter 5 months and was treated with left hepatectomy. Conclusion: Additional use of laparoscopic ultrasound enables the detection , differentiation, and treatment of deep, nonvisualized cystic lesions (two patients, 16.6%) and validation of the adequacy of the laparoscopic proced ure.
