Objective To study the diagnosis,treatment and therapeutic results of 11 patients who suffered from mucinous tumor of the bile duct.Methods Eleven patients who were diagnosed to suffer from mucinous tumor of the bile duct were retrospectively studied.Three patients who presented with obstructive jaundice were diagnosed on ERCP,and 8 patients who had extra-and intrahepatic cholangiolithiasis were diagnosed by biopsy during choledochoscopy.Results One of the 3 patients who underwent ERCP died from obstructive jaundice after failed drainage of bile using endoscopic nasobiliary drainage (ENBD).The remaining two patients underwent laparoscopic common bile duct exploration and T tube drainage.The eight patients who had extra-and intrahepatic cholangiolithiasis were diagnosed by biopsy during choledochoscopy.Conclusions The clinical presentation of mucinous tumor of bile duct is non-specific and the preoperative misdiagnosis rate is high.Common bile duct exploration,T tube drainage and long-term T tube drainage is a good way to treat mucinous tumor of the bile duct.

The clinical data of 143 patients with type Ⅱ a hepatolithiasis with normal function of the sphincter of Oddi were analyzed.The patients were divided into two groups at random.The data of the 2 groups of patients were compared on the operating time,hospitalization,rates of complication,residual stone rates and recurrence rates.The A group patients underwent laparoscopic video choledochoscopic hepaticocholangiolithotomy,T-tube drainage and choledochoscopic lithotomy.The B group patients underwent laparoscopic video hepatectomy and choledochoscopic lithotomy.For most of the patients in the A group,the treatment had the advantages of less trauma,less complications and quicker recovery.There was no significant differences in residual stone rates and recurrence rates between the two groups.As it was difficult to remove stones in the caudate lobes of Ⅱ a type patients in A group due to the sharp angle between the hepatic duct and bile ducts of the caudate lobe,individualized programs should be adopted according to the location of stones on individual patients.

Objective To observe the effect and quality of life score of laparoscopic choledochotomy and T tube drainage for the patients of extrahepatic bile duct stones.Methods A total of 80 patients with calculus of extrahepatic bile duct in Shandong Provincial Third Hospital from February 2016 to April 2017 were retrospectively analyzed,including 41 males and 39 females,among which,40 patients were treated with laparoscopic choledocholithotomy and T tube drainage(the study group),and the other 40 cases were operated on laparotomy (the control group) by hierarchical randomization grouping.After operation,the time of operation,the amount of bleeding during the operation,the time of postoperative exhaust,the time of postoperative hospitalization and the difference of adverse reactions were observed in the two groups.Follow-up at the end of 1 st and 3th month,quality of life score was compared between the two groups.The measurement data with normal distribution were expressed as mean ± standard deviation (Mean ± SD),comparison between groups were performed using t test.The count data were expressed as rate(％),comparison between groups were performed using chi-square test.Results Comparison of data between the study group and the control group:operation time respectively were (97.23 ± 10.21) min,(117.52 ± 10.01) min,the amount of bleeding respectively were(87.73 ± 10.54) ml,(185.13 ± 11.56) ml,postoperative exhaust time respectively were (17.57± 2.96) h,(38.44 ± 3.06) h and the postoperative hospitalization time were (7.75 ± 1.21) d,(12.03 ± 3.85) d.The data of each group in the study group were lower than those in the control group,and the difference was statistically significant(P ＜ 0.05).The quality of life scores of the 1 months and 3 months after treatment in the study group were (45.82 ± 3.22) scores and (47.29 ± 3.09) scores,the control group were (32.56 ± 3.29) scores and (36.19 ± 3.06) scores.The study group was significantly superior to the control group,and the difference was statistically significant(P ＜ 0.05).The complications of the patients in the study group were not statistically significant between the control group and the control group(P ＞ 0.05).Conclusions Compared with open surgery,laparoscopic choledocholithotomy with T tube drainage has significant clinical effect in the treatment of extrahepatic bile duct stones.It can improve the quality of life and safety,and it is suitable for clinical application.
