【Abstract】Objective To investigate the features of gallbladder carcinoma in two-phase spiral CT, and to analysis the values of two-phase spiral CT for the differential diagnosis between gallbladder carcinoma and chronic cholecystitis. Methods The two-phase spiral CT manifestations of 30 cases of gallbladder carcinoma, proved by surgery and pathology, and 30 cases of chronic cholecystitis were analyzed. Results According to the CT findings, the gallbladder carcinoma was categorized into 3 types: intraluminal mass of gallbladder in 6 out of 30 (20.0%）， thickening of the gallbladder wall in 11 (33.7%), and mass replacing the normal gallbladder in 13(43.4%). The most common enhancement patterns of the wall in gallbladder carcinoma were hyperattenuation during the arterial phase, while isoattenuation with the adjacent hepatic parenchyma during the venous phase; or hyperattenuation during both phases. The most common enhancement pattern of the wall in chronic cholecystitis was isoattenuation during both phases, with clear hypoattenuation linear shadow in the gallbladder fossa. Other ancillary features of gallbladder carcinomas included: infiltration of the adjacent parenchyma, local lymphadenopathy and intrahepatic metastasis. Conclusion Two-phase spiral CT scan can identify the features of the gallbladder carcinoma and is helpful for the differential diagnosis of these two different disease entities.
Objective To explore the effects of bile from patients with cholecystolithiasis on the growth of human gallbladder carcinoma cells GBC-SD and the potential correlation between cholecystolithiasis and gallbladder carcinoma. Methods Cholecystolithiasis bile (CB) and normal bile (NB) specimens were used for this study. The proliferative effects of bile were measured by methabenzthiazuron (MTT) assay and cell cycle and apoptosis were analyzed by flow cytometry. Results CB can significantly promote the proliferation of GBC-SD cells, GBC-SD proliferative index increased significantly after treated with 1% CB for 48 h （P＜0.05）.The Sphase fraction of CB 〔（49.26±8.07）%〕 increased remarkably (P＜0.05) compared with that of NB 〔（25.54±6.57）%〕, and the CB percentage of G0/G1 phase 〔（40.59±9.12）%〕 decreased remarkably (P＜0.05) compared with NB 〔(60.64±13.42）〕%. Conclusion CB can promote the proliferation of human gallbladder carcinoma GBC-SD cells.
Objective To explore the prevention and treatment of injury to brangches of the middle hepatic vein in laparoecopic cholecystectomy. Methods The clinical data of 27 hemorrhage cases of injury to brangches of the middle hepatic vein in laparoscopic cholecystectomy from January 2008 to January 2010 were analyzed retrospectively. Results All 27 hemorrhage cases were successfully stopped bleeding under laparoscopy by the way of packing hemostasis （n=17）, clamping hemostasis （n=6）, and suturing hemostasis （n=4）. In the 3 hemostasis methods, the operating time and amout of bleeding in the cases with packing hemostasis was the shortest and the least, respectively, which was （90.26±12.46） min and （240.32±80.15）ml, respectively, but the differences of the 3 methods were not statistical significance （P＞0.05）. Conclusions During laparoscopic cholecystectomy, gallbladder bed should be seperated in the correct plane to avoid injury to brangches of the middle hepatic vein. The most important to ensure surgery safety is applying the right surgical hemostasis method to stop bleeding quickly, and the open surgery will be the first choice in the right time when the difficult hemostasis occurs under laparoscopy.
ObjectiveTo discuss the clinical effects of T-tube with side holes in the gallbladder-common hepatic duct anastomosis. MethodsThe clinical data of 60 cases that performed gallbladder-common hepatic duct anastomosis from Jul. 2009 to Jul. 2012 were retrospectively analyzed. The contractile functions and mucosal recovery of gallbladder were compared between the conventional T-tube and T-tube with side holes. ResultsTwenty-four cases of gallbladder-common hepatic duct anastomosis used conventional T-tube, the gallbladder were not developing in 6-8 weeks after operation by T-tube cholangiography, the gallbladder mucosa of 17 cases were normal without edema, congestion and edema were observed in 6 cases, and the normal gallbladder mucosa structure disappeared in 1 case. The gallbladder were developing in 6-8 weeks after operation by T-tube cholangiography in 36 cases that used T-tube with side holes, the gallbladder mucosa structure had not congestion, edema, and erosion. The gallbladder contractile function were normal. ConclusionsThe floc, blood clots, and inflammatory substances in gallbladder can be discharged into the intestine or drainage in vitro, and the bile can go into gallbladder and can be concentrated through the T-tube with side holes. Physiological flow of bile can return to normal and the function of gallbladder can recover early.
To study the expressions of CA19-9 and CA125 and their clinicopathologic significancesin gallbladder adenocarcinoma , pericancerous tissues and chronic cholecystitis. Methods EnVisionTM immunohistochemist ry was used for assaying the expressive levels of CA1929 and CA125 in the routinely paraffin2embedded sections of specimens f rom gallbladder adenocarcinoma ( n = 108) , pericancerous tissues ( n = 46) , and chronic cholecystitis ( n = 35) . Results The positive rates of CA19-9 and CA125 were significantly higher in gallbladder adenocarcinoma ( 49. 1 % , 51. 9 %) than those in pericancerous tissues ( 26. 1 % , 15. 2 %) and chronic cholecystitis(14. 3 % , 5. 7 %) , respectively ( Plt; 0. 01) . The positive rates of CA19-9 and CA125 were significantly lower in thecases of adenomatous canceration , maximal diameter lt; 2 cm , no-metastasis of lymph node and no-invasion of regional tissues than those in the ones of low-differentiated adenocarcinoma , maximal diameter ≥2 cm , metastasis oflymph node and invasion of regional tissues ( Plt; 0. 05 , Plt; 0. 01 ) . The consistence of CA19-9 and CA125 expressivelevels was found in gallbladder adenocarcinoma (χ2 = 44. 69 , Plt; 0. 01) . Conclusion The expressions of CA19-9 andCA125 may be important tumor markers to reflect the carcinogenesis , progression , biological behaviors and prognosis of gallbladder adenocarcinoma.
From the March of 1993 to the May of 1994, we had performed laparoscopic cholecystectomy (LC) for 200 patients of the age ranged 19-77 years. In these cases, 12 had previous abdominal surgery; 3 cases had hepatic cysts; 11 cases had stones in the neck of gall bladders. We had successfully performed LC for 190 cases (95%). But we also had some unsuccesful experiences, including accidental injury to the stomach or duodenum, and bleeding from cystic arteris of the gallbladder. Operation (LC) was abandoned in one patient because of severe cardiac arrhyshmia developed during operation, and billiary tract injury was found postoperatively in three patients with no postoperative death. The operative indications and technical problems of LC are discussed in detail and measures in avoiding injury to billiary or GI tract from LC are introduced.
Objective To explore the effect of gallbladder preserving surgery with laparoscope and choledochoscope.Methods The data of 60 cases of gallbladder preserving surgery with laparoscope and choledochoscope （observation group） and carried out with the same period 61 cases of small incision gallbladder preserving surgery （control group） between June 2008 to January 2013 were retrospective analyzed. Results All patients were followed up for （18±2.4）months （6-36 months）. The intraoperative blood loss， postoperative gallbladder hemorrhage rate， gallbladder dysfunctionrate， postoperative hospitalization time， stone recurrence rate， and reoperation rate in observation group were less orlower or shorter than the control group （P＜0.05）. The operative time and hospital costs in observation group were longeror higher than that of the control group （P＜0.05）. The rest of the observation index of two groups were no significant differences （P＞0.05）. Conclusions The gallbladder preserving surgery with laparoscope and choledochoscope is safeand feasible in technique level， and the short-term effect after operation is better. But the operation indications must be controlled strictly. The long-term efficacy needs further accumulation of cases and collect enough evidence to verify.
Objective To enhance survival rate and treatment effect for advanced gallbladder cancer (GBC). MethodsEighty cases of advanced GBC were treated surgically from January 1990 to June 2001.Seventyone cases had obstructive jaundice, 15 had palpable abdominal mass. Extended radical cholecystectomy was performed in 39 cases of advanced GBC in which the tumor invaded the surrounding organs or tissues but without distant metastasis. ResultsFollowup showed that the survival period was between 8 and 37 months (average 18.1 months), 1， 2 and 3year survival rates were 43.6%， 20.5% and 5.1% respectively. Palliative operations were performed in other 41 advanced GBC cases with distant metastasis. All of the patients died within one year. Conclusion This result suggests that extended radical cholecystectomy is effective for advanced GBC.
Objective To evaluate the clinical application value of the tauro ursodeoxycholic acid (TUDCA) for preventing the relapse of lithiasis after the gallbladder-protected lithotomy. Methods Totally 80 cholecyslithiasis patients in Chengdu General Military Hospital who met the demand of lithotomy in protecting gallbladder were divided into two groups by random permutations, with 40 patients in each. The calculus was removed by using the percutaneous ultrasonic lithotripsy in order to preserve the well-functioning gallbladder. The patients in the trial group were given TUDCA after surgery for two years, whereas the patients in the control group received the same nursing and diet therapies without medication. The thickness of gallbladder wall and the contraction function of gallbladder were checked two years after surgery, the statistics of the recurrence rate of liary calculus symptoms and cholecyslithiasis were conducted, and the comparison between those two groups was performed. Results All the operations of gallbladder-protected lithotomy were successful. There was significant difference between those two groups two years after surgery in terms of the thickness of gallbladder wall and the contraction function of gallbladder (Plt;0.05). The relapse of lithiasis was remarkably decreased in the trial group (Plt;0.05). Conclusion The application of TUDCA for patients with gallbladder-protected lithotomy can prevent the relapse of cholecyslithiasis.
