Objective: LT has become the gold standard treatment for many liver diseases, especially chronic liver disease. A commonly seen problem, even in donors who do not develop any major complications after living donor hepatectomy (LDH), is the persistent drainage of lymphatic fluid from the hepatectomy site drain, which causes extensive hospitalization and consequent loss to the workforce. To our knowledge, no study has yet been published comparing LVSS and conventional knot-tying methods for hilar dissection, which is an important stage of the LDH procedure. We aimed to prospectively compare the outcomes of these two treatment methods.
Patients and methods: Donor candidates were divided into two groups: conventional suture tying (conventional knot tying group; n=34) and Ligasure vessel sealing system (LVSS; n=34). A simple randomization method of drawing lots was used to assign the patients to each group. The following parameters were analyzed for all patients: age, gender, BMI, duration of surgery, postoperative drainage amounts, drain removal times and complications, length of hospital stay, morbidity, and mortality.
Results: There were no significant differences in terms of operative times, postoperative drainage levels, hospital stay or drain removal times.
Conclusions: In this study, the use of LVSS in LDH was found to be safe, although it did not offer any advantage over conventional methods. Nevertheless, it seems probable that the use of LVSS could reduce operative time and amounts of lymphatic drainage, especially in centers with minimal experience with LDH, such as new LDH centers.
