ABSTRACT
Objective To explore the feasibility of two-port laparoscopic drainage in the treatment of liver abscess. Methods A total of 18 patients with bacterial hepatic abscess underwent twoport laparoscopic drainage.Two incisions were made at the superior border of the umbilicus and 4～5 cm below the right costal margin near the anterior axillary line,respectively.The abscess was cut through in "┼" or "╫" shape.The pus cavity was debrided bluntly,and a double-lumen drainage tube was placed.Results The laparoscopic drainage was performed successfully in all the 18 patients.The operative duration was 30～75 min(mean,45 min).A bile leakage for 80～100 ml per day occurred in 1 patient.The drainage tube was removed on the 12th postoperative day and the patient was discharged from hospital on the 14th postoperative day.Of the 18 patients,the hospital stay after operation was 7～14 d(mean,8.5 d).All the patients were followed for 5～12 months(mean,9 months) and no residual abscess or recurrence was found. Conclusions Two-port laparoscopic drainage for liver abscess is an ideal approach with advantages of simple manipulation,slight contamination inside abdominal cavity,little trauma,low complication rates,and rapid recovery.
ABSTRACT
Objective: To better understand homing potentiality of hematopoietic stem cells (HSC) in human umbilial cord blood (UCB) and the mechanism of dextran sulfate (DS) mobilization. Methods: Sub lethally irradiated or DS pretreated severe combined immunodeficient (SCID) mice were transplanted with UCB, which was cryopreserved at -80℃.Human cells in recipient mice were detected by flow cytometry and CFU GM assay from each host organ. Results: In contrast with the controls, engraftment after irradiation or administration of DS resulted in a higher percentage of CD45 +,CD34 +,CD19 + cells produced in SCID mice. While comparison between the experimental groups, higher implantation level was obtained in the former if equivalent donor cells were used in both groups. Conclusion:DS is a safe and effective pretreatment, which can mobilize HSC, but also vocate niches for transplanted HSC homing. [
