T-tube drainage appeared to result in significantly longer operating time and hospital stay compared with primary closure without any apparent evidence of benefit on clinically important outcomes after open common bile duct exploration. Based on the currently available evidence, there is no justification for the routine use of T-tube drainage after open common bile duct exploration in patients with common bile duct stones. T-tube drainage should not be used outside well designed randomised clinical trials. More randomised trials comparing the effects of T-tube drainage versus primary closure after open common bile duct exploration may be needed. Such trials should be conducted with low risk of bias and assessing the long-term beneficial and harmful effects of T-tube drainage, including long-term complications such as bile stricture and recurrence of common bile duct stones.
Choledochotomy for biliary lithiasis: T-tube drainage or primary closure. Effects on postoperative bacteremia and T-tube bile infection.
To compare the incidence of postoperative bacteremia in patients with biliary lithiasis after choledochotomy supplemented by either T-tube drainage or primary common bile duct closure, 117 patients who underwent surgery are presented in this clinical trial. It has been shown that primary common bile duct closure is associated with a lower incidence of postoperative bacteremia (3.3 percent), a lower mortality rate (0 percent), and a lower early morbidity rate (13.3 percent) than T-tube drainage (31.5, 3.5, and 36.1 percent, respectively). The above evidence supports the view that T-tube drainage might well provoke the exogenous acquisition of environmental microorganisms and thus promote further infection.
