Abstract:
Objective To explore the risk factors affecting T-tube sinus tract formation after common bile duct exploration and T-tube drainage by spiral computed tomography (SCT)examination.Methods The clinical data of 465 patients undergoing common bile duct exploration and T-tube drainage at the Affiliated Hospital of Youjiang Medical College for Nationalities from May 2011 to December 2013 were retrospectively analyzed.The residual stones and biliary stricture were detected by T-tube cholangiography,and the T-tube sinus tract formation in all the patients was detected by SCT examination at postoperative week 2.The factors affecting sinus tract formation were analyzed,including gender,age,albumin (Alb),C-reactive protein,alanine transaminase (ALT),total bilirubin (TBil),hemoglobin (Hb),surgical method,effusion around T tube,reoperation,diabetes.Univariate analysis was done using the chi-square test.Multivariate analysis was done using the Logistic regression.Results T-tubes of 465 patients were clear without residual stones.T-tube in the 397 patients was removed when the sinus tract formation was confirmed by CT examination at postoperative week 2.T-tubes in other patients were removed when the sinus tract formation was detected by CT reexamination at postoperative week 4.In univariate analysis,Alb,surgery method,effusion around T-tube and diabetes were important factors affecting T-tube sinus tract formation (x2 =50.750,7.671,19.022,15.373,P ＜ 0.05).Alb ＜ 30 g/L,laparoscopic surgery,effusion around T-tube and diabetes were independent risk factors affecting T-tube sinus tract formation in multivariate analysis [Odds ratio =1.135,0.493,0.262,0.363; 95％ confidence interval:1.061-1.214,0.280-0.865,0.104-0.658,0.156-0.843,P ＜ 0.05].Conclusions The T-tube removal is determined according to the sinus tract formation by CT examination at week 2 after common bile duct exploration and T-tube drainage.Alb ＜ 30 g/L,laparoscopic surgery,effusion around T-tube and diabetes are independent risk factors affecting T-tube sinus tract formation.
