Objective To introduce the current status of clinical research on endoscopic cholecystolithotomy with reservation of gallbladder. Methods Literatures related to the basis, advantage, indication, contraindication, operative method and current controversy were reviewed and summarized. Results The objective evidences were afforded by postoperative complications of cholecystectomy for endoscopic cholecystolithotomy with reservation of gallbladder. The progress of endoscopic technique made it possible for reservation of gallbladder. The controversy in endoscopic cholecystolithotomy with reservation of gallbladder was focused on the choice of indications and operative procedure. Incorrect patient selection and undue pursuit of cholecystolithotomy with reservation of gallbladder would be completely opposite to the treatment of gallstone. Conclusion It is feasible for endoscopic cholecystolithotomy with reservation of gallbladder to remove completely stone and reserve gallbladder function, but further investigation and long-term follow up are required to delineate gallstone recurrence after operation.
Objective To evaluate the clinical efficacy of t ransplantation of autologous peripheral blood stemcells ( PBSC) for the t reatment of lower limb arterial ischemic disease. Methods From March 2004 to February2007 , 16 patient s with severe lower limb arterial ischemic disease were t reated with autologous PBSC t ransplantation. Recombinated granulocytecolony stimulating factor ( G2CSF) was used to mobilize the proliferation of bonemarrow stem cells and then the stem cells were released into peripheral blood. Af ter 5 - 6 days , PBSC were collected by CS23000 PLUS blood2cells separator. Such concent rated stem cells fluid was int ramuscularly injected into theischemic areas of the lower limbs. Results The result s of 3 to 242month following2up after the t ransplantation ofstem cells showed that the resting pains of the affected limb were greatly relieved , and ulcers were healed. The distance and duration of intermittent limping became farther and longer. Conclusion Transplantation of autologousPBSC would be a novel and effective method for the t reatment of arterial ischemic disease. However , this method isstill at the stage of initial clinical application , so it still need to be further studied.
Objective To evaluate the impact of transcatheter arterial chemoembolization（TACE） on survival and tumor recurrence in patients with primary liver cancer， provide reference of clinical diagnosis and treatment for the primary liver cancer patients. Methods Two hundred and twenty-two cases of primary liver cancer were divided into TACE group （n=110） and control group （n=110）， TACE was performed after operation in the TACE group， convention treatment was performed after operation in the control group. The survival and tumor recurrence rates were compared between the TACE group and control group. Results The 1-， 2-， and 3-year survival rates were 83.64%， 56.36%，and 42.73% in the TACE group， respectively， which were 65.45%， 40.91%， and 21.82% in the control group，respectively. The differences were statistically significant （P＜0.05）. The 1-， 2-， and 3-year tumor recurrence rates were 20.91%， 54.55%， and 67.27% in the TACE group， respectively， which were 38.18%， 57.27%， and 70.91% in the control group， respectively. The 1-year tumor recurrence rate in the TACE group was significantly lower than that in the control group （P＜0.05）， but the differences of the 2- and 3-year recurrence rates were not statistically significant（P＞0.05）. Conclusions TACE treatment for primary liver cancer patients can increase long-term survival， but can’tdecrease long-term recurrence.
