Objective To compare the clinical efficacy between endoscopic thyroidectomy via breast approach conventional open thyroidectomy in patients with nodular goiter. Methods A series of 70 patients with unilateral nodular goiter divided into two groups, either receiving endoscopic thyroidectomy through breast approach(endoscopic group,35 cases),or conventional open thyroidectomy(open group,35 cases). The therapeutic efficacy was compared between the two groups. Results The operating time of endoscopic group was significantly longer in the endoscopic group (100.4±26.6)min than in the open group (73.5±14.5) min(t=5. 627, P=0. 000). The postoperative drainage volume in the endoscopic group (66.7±24.9) ml significantly more than that in the open group ( 13.3±6.4)ml( t = 14. 403, P = 0. 000 ). The postoperative hospital stasignificantly longer in the endoscopic group (4.3±1.1 )d than in the open group (3.6±0.9)d(t=2.886, P=0.005). And a satisfactory cosmetic result was achieved in significantly more patients in the endoscopic group(9/24 cases) than in the open group(34/51 )(x2 = 7.235, P=0.007). There was no significant difference in intraoperative loss between the endoscopic group (22.5±15.3)ml and the open group (18.3±7.5 )ml(t=1.273, P=0.207), a consumption of analgesics between the endoscopic group (9/24 eases) and the open group(21/51 cases) (X2=0.028, P=0.867), respectively. No severe complications was encountered ,such as massive hemorrhage,injuries of the recurrent or sularyngeal nerve, or parathyroidgland injury. Conclusion Both breast approach endoscopic thyroidectomy and conventional open thyroidectomy are safe and effective, former gives better cosmetic outcomes.

Objective To investigate the feasibility of establishing a digital model of juxtahepatic vena cava.Methods The clinical data of 120 participants (without liver diseases) who were admitted to the Cangzhou Central Hospital from January 2013 to May 2013 were collected.The results of computed tomography were analyzed.The diameters of juxtahepatic vena cava on different levels (P1 plane:inferior vena cava at the entrance to the right atrium,P2 plane:the upper margin of the roots of hepatic veins,P4 plane:lower boundary of liver,P5 plane:confluence of renal veins and inferior vena cava),and the circumference of the inferior vena cava and the lengths between these levels were recorded.A digital model of juxtahepatic vena cava was established by these data on the premise that the juxtahepatic vena cava was engorged.All data were analyzed using the analysis of variance,paired sample t test and independent samples t test,and correlation and regression were used in analysis of relations between there data.Results Data of the P1 plane and P2 plane were both missed in 3 cases,and the data of the P4 plane was missed in 8 cases.The theoretical diameter of hepatic vena cava at the P1,P2 and P4 planes were (28.1 ± 4.0) mm,(28.7 ± 3.5) mm and (23.5 ± 2.7) mm,respectively.The median diameter of hepatic vena cava at the P5 plane was 24.3 mm.The juxtahepatic vena cava was a 3 dimensional structure of cylinder with a slightly protruding middle part.There were significant differences in P1D-P2D,P2D-P4D,P1D-P4D (F =77.5,P ＜ 0.05).There were significant differences between P2D-P4D and P1D-P4D (t =14.893,11.210,P ＜ 0.05).The median length of hepatic vena cava between P1 and P2 planes was 7.5 mm.The lengths of hepatic vena cava between P1 and P4 planes,P2 and P4 planes were (85.2 ± 11.0)mm and (78.2 ±9.8)mm,respectively.The median length of hepatic vena cava between the P4 and P5 planes was 10.0 mm.P1D-P2D,P2D-P4D,P2D-P5D and P4D-P5D were positively correlated (r =0.862,0.308,0.186,0.788,P ＜ 0.05),while P1D-P4D and P2D-P5D did not correlated (r =0.180,0.118,P ＞0.05).P2D was correlated with the body weight,and P5 D was correlated with the age (r =0.200,0.130,P ＜ 0.05).The P1 D,P2D,P4D and P5 D of the inferior vena cava were (28.5 ± 3.7) mm,(29.0 ± 3.4) mm,(23.9 ± 2.8) mm and (24.3 ± 2.6) mm in males,and (27.8 ±4.2) mm,(28.5 ± 3.6) mm,(23.1 ± 2.5) mm and 24.0 mm in females.There were no significant difference in P1D,P2D,P4D and P5D between males and females (t =0.911,0.809,1.588,1.902,P ＞ 0.05).The length between P1 and P2 planes was negatively correlated with P1D and P2D (r =-0.245,-0.160,P ＜ 0.05),while the length between P4 and P5 planes was positively correlated with P1D (r =0.149,P ＜ 0.05).The length between P2 and P4 planes was positively correlated with P2D (r =0.195,P ＜ 0.05).The length between P1 and P2 planes did not correlated with the age,height and body weight (r =-0.092,-0.047,-0.033,P ＞ 0.05).The lengths between P2 and P4 planes,P1 and P4 planes were negatively correlated with the age (r =-0.343,-0.371,P ＜ 0.05),but positively correlated with the body weight (r =0.271,0.208,P ＜ 0.05).The length between P4 and P5 planes was positively correlated with the height and body weight (r =0.154,0.255,P ＜ 0.05).There were no significant difference in the lengths between P1 and P2 planes,P1 and P4 planes,P2 and P4 planes,P4 and P5 planes between males and females (t =-1.046,-1.274,-0.908,1.375,P ＞ O.05).The length between P2 and P4 planes was similar to the length of retrohepatic vena cava.The length between P2 and P4 planes(mm) =71.23-0.293 × age (years) +0.32 × body weight (kilogram).Conclusion The establishment of digital model of juxtahepatic vena cava based on the computed tomography imaging data is feasible,which provides basis for clinical investigation.

Objective To study the efficacy of surgical treatment in hilar cholangiocarcinoma patients. Methods One hundred and four cases underwent surgical treatment of hilar cholangiocarcinoma were retrospective enrolled in the study from 1998 to 2008, including 45 cases of radical resection, 38 cases of palliative resection, vitro bridge drainage in 21 cases, 93 cases of postoperative patients. Ninty-three patients were followed up for 5 - 67 months, the different procedures of the treatment was summerized. Results Oneyear survival rate of radical resection and palliative resection was 80. 0% ( 32/40 ) and 86. 8% ( 33/38 ),respectively. No significant difference between the two groups (P ＞0. 01 ) were found; 2-year survival rate was 67. 5% (27/40) and 39. 5% ( 15/38), with significant difference between the two groups (P ＜0. 01 ) ;3-year survival rates were 37.5% ( 15/40 ) and 13.2% ( 5/38 ), with significant difference between the two groups (P＜0. 05). Palliative resection had higher 1-year survival rate than in vitro bridge drainage(P ＜ 0.01).Conclusion Surgical treatment of hilar cholangiocarcinoma is the most effective way to prolong the survival time of radical resection, radical surgery had better efficacy than palliative surgery, and palliative surgery is superior to external drainage. In patients of severe jaundice combined with biliary drainage infection, preoperative bridge drainage would improve the safety.
