Background:
There has been no solid evidence regarding the actual efficacy of adhesion barriers in liver surgery.
Methods:
Difficulty grade of lysis of adhesion was evaluated in 122 patients who underwent repeat hepatectomy (ReHx) using the TORAD score. Technical difficulty of lysis of adhesion and incidence of complication were then compared between the group of patients who received a sheet-type adhesion barrier (Seprafilm®) in the previous hepatectomy (n = 70) and those who did not (n = 52) using the inverse probability weighting method.
Results:
Use of Seprafilm was significantly associated with lower grade of difficulty of lysis of adhesion according to the TORAD score (P < 0.001). Postoperative morbidity rate was lower and postoperative stay was shorter in the Seprafilm group in the propensity-score adjusted population (37% vs. 74%, P < 0.001 and 12 days vs. 14 days in median, P = 0.048). Multivariate analysis confirmed that use of Seprafilm was independent predictor for severity of adhesion (odds ratio [OR] 0.24, 95% CI, 0.09-0.65, P = 0.005) and decreased incidence of postoperative morbidity at ReHx (OR, 0.34; 95% CI, 0.14-0.84, P = 0.020).
Conclusions:
Use of Seprafilm may be associated with decreased technical difficulty of lysis of adhesion and may correlate with lower risk of postoperative morbidity in patients undergoing ReHx.
