ABSTRACT
INTRODUCTION: Liver cancer is one of the most common malignancies of the digestive system. Minimally invasive ablation procedures have become one of the major means for treating unresectable multifocal liver cancer and have been extensively applied in primary and metastatic liver cancer treatment. Laparoscopic B-ultrasound-guided microwave ablation is an example of the progress made in this field. AIM: To analyze and summarize the results of and experience with laparoscopic B-ultrasound-guided microwave ablation for multifocal primary liver cancer; moreover, the ablation effects were compared between tumors of different sizes. MATERIAL AND METHODS: Laparoscope-guided needle ablation was conducted on 84 lesions from 32 patients with primary liver cancer based on tumor size, quantity, and location. Moreover, the perioperative data, ablation effects according to tumor size, and long-term follow-up results were analyzed. RESULTS: Among the 84 nodules treated via microwave ablation, tumors measuring ≤ 3 cm demonstrated complete ablation upon imaging analysis conducted 1 month after surgery. Moreover, 5 of the tumors measuring > 3 cm demonstrated incomplete ablation. In these cases, a second procedure was performed, until imaging studies confirmed that complete ablation was achieved. CONCLUSIONS: Laparoscopic microwave ablation allows for precise puncture positioning, an effective ablation range, and safe and feasible surgery, which is especially suitable for liver tumors located in sites difficult to access.
ABSTRACT
The aim of this study was to analyze clinical treatment and outcome of injection MTX for Cesarean scar pregnancy (CSP). We use retrospective study to compare the time in CSP of blood chorionic gonadotropin (ß-HCG) and progesterone drooped to the normal, blood flow resistance and hospitalization days. 34 patients diagnosed with CSP were reviewed in our department from 2000 to 2013, including clinical characteristics, early diagnosis, treatment methods and treatment outcome. All patients were divided into B ultrasound-guided gestational MTX inject group (Group one), local intramuscular treatment group (Group two) and uterine artery perfusion MTX group (Group three). All cases had responded well to treatment. Except three cases of local intramuscular serum ß-HCG decreased slowly MTX 10 mg intramuscular again, the average serum ß-HCG decline of 65% the 4th day after treatment. In intramuscular group, the average length of stay is 19 ± 2.1 days. Serum ß-HCG, progesterone recovery time were 20 to 89 days, an average of 54.5 days. B ultrasound-guided group hospital stay were 15 ± 3.1 days, serum ß-HCG, progesterone recovery time were 18 to 71 days, an average of 44.5 days. In Uterine artery embolization group, the average length of stay is 16 ± 2.4 days, serum ß-HCG, progesterone recovery time were 20 to 70 days, an average of 45 days. Statistical data results using T-test and chi-square test analysis. Three groups of ß-HCG, progesterone decreased to normal days the difference was statistically significant (P < 0.05), but uterine artery embolization group and ultrasound-guided group B showed no significant difference (P > 0.05). B ultrasound-guided gestational injection of MTX and uterine artery embolization perfusion MTX are the better ways to treat uterine scar pregnancy.
ABSTRACT
Objective To investigate the application value of B-ultrasound guided liver puncture biopsy in antiviral therapy for chronic hepatitis B. Methods 20 cases with chronic hepatitis B proposed antiretroviral treatment got liver biopsy for grading the degree,and had anti-viral treatment.We had analysis before and after treatment.Results Pathology results showed that grading of inflammation and fibrosis in varying degrees improved.Comparison of before and after treatment had statistical significance(P
ABSTRACT
Objective To explore the clinical value of B ultrasound-guided psychro-circulation percutaneous microwave coagulation therapy(PMCT) in the treatment of liver cancer.Methods One hundred and sixteen liver cancer patients with 154 lesions were selected to receive psychro-circulation PMCT in our department from July 2004 to December 2007.The pre-and postoperative alpha fetoprotein(AFP) levels were detected.The diameters and blood flow state of the tumors were measured and compared by use of B ultrasound and computerized tomographic scanning(CT).The postoperative 1,2 and 3 y survival rate of those patients was followed up and recorded.Results No mortality or severe complications occurred in this series.Preoperative serum AFP level of the patients was(421.6?36.5)?g/L and decreased obviously to(232.5?25.6)?g/L at 1 month after psychro-circulation PMCT(P
