Filter by:Intraoperative fluorescent cholangiography (IFC) with concomitant fluorescent angiography is a recently developed method for non-invasive visualisation of the relevant anatomy during laparoscopic cholecystectomy. The objective of this study was to assess the time required by routine-use of IFC and to evaluate success-rate of the procedures. Methods Thirty-five patients scheduled for laparoscopic cholecystectomy and operated by the same surgeon were consecutively enrolled. A standardized protocol with IFC including concomitant angiography was performed during laparoscopic cholecystectomy. Intra-operative time-registration and exposure of predefined anatomical structures were recorded.
Objective:To explore the role of the right portal pedicle and Rouviere's sulcus as an anatomic landmark in laparoscopic cholecystectomy. Methods:The investigators are going to select 60 patients intending to perform Laparoscopic cholecystectomy from April 2014 to April 2015.Check out the presence of the right portal pedicle and Rouviere's sulcus during the surgery and divide into the experimental group and the control group.Experimental group operated in Laparoscopic cholecystectomy with the guide of Rouviere's sulcus while the Control group operated with the traditional way. Research hypothesis:Compare the differences between the Experimental group and the Control group in bile duct injury rate,complication rate,blood loss,operative time ,conversion rate and hospital stay.It is supposed that the results of Experimental group are superior to the control group,difference is statistically significant(P<0.05). So the investigators can draw the conclusion that the anatomy method with the guide of right portal pedicle and Rouviere's sulcus is useful in laparoscopic cholecystectomy.
Objective:the purpose of this study is to investigate the efficacy,feasibility,reliability,and safety of laparoscope combined air-pressure ballistic lithotripsy in the treatment of patients with bile duct stones. Methods:We are going to select 60 patients diagnosed with hepatolithiasis who carry on the treatment in our hospital from April 2014 to April 2015.According to the unified inclusion and exclusion criteria,the patients are divided into the experimental group and the control group.The experimental group use the treatment of laparoscope combine with air-pressure ballistic lithotripsy to treat hepatolithiasis,while the control group treat the patients with hepatolithiasis with the method of lobectomy and segmental resection of liver.Contrastive analyzed two group of patients' clinical care effects. Research hypothesis:according to compare two groups' duration of surgery,blood loss,postoperative complication rate,hospital stay,the stone clearance rate,,the residual stone rate,reoperation rate etc.We suppose that the clinical results of the experimental group are superior to the control group,difference is statistically significant(P<0.05).So we can draw the conclusion that the method of laparoscope combined air-pressure ballistic lithotripsy is useful in treatment of patients with hepatolithiasis.
Laparoscopic Cholecystectomy applied to Artificial pneumoperitoneum and the extent of Surgical stimulation cause the wave of hemodynamics increase vigorously, which make it difficult to judge the depth of anesthesia according to traditional hemodynamics index such as heart rate and blood pressure.In case of this, the investigators design this research to study the Closed-Loop Target Controlled Infusion to anaesthesia of individualization guided by a Narcotrend index monitor in Laparoscopic Cholecystectomy.

The objective of this study is to determine if IV acetaminophen administered intraoperatively can decrease the dose of narcotics required for adequate pain control and shorten recovery time in the PACU specifically in obese patients at risk for obstructive sleep apnea.
We found a new Double sphincter which located in the neck of gallbladder，we supposed it may be related to control pressure of bile duct.Its formation is related to genetic factors.
Analgesic efficacy of multi-modal analgesia is superior to standard analgesia for patients undergoing elective laparoscopic cholecystectomy for symptomatic cholelithiasis. Topical cystic plate and port-site incision 0.25% bupivacaine significantly reduces pain after laparoscopic cholecystectomy.
The trial aims to assess the value of two-regimen antibiotic prophylaxis versus placebo in elective laparoscopic cholecystectomy.
The burden of iatrogenic bile duct injury (BDI), the most feared complication of laparoscopic cholecystectomy (LC), is extremely high and the repercussions on the patient's outcomes may be severe ranging from intraoperative repair to liver transplant or patient's death. Different techniques have been proposed to prevent BDI. Our hypothesis is that a fluorescence-based Imaging would allow visualization of the biliary tree anatomy as good as with the Intraoperative Cholangiogram with several main advantages: 1. ease of use 2. lack of invasiveness 3. absence of ionizing radiation to the patient and the operating staff 4. performed prior to any dissection (prior to "critical view of safety") Capacity of enhanced-reality based on virtual cholangiography (computer treatment of MRI images) to guide biliary tree anatomy visualization will be also evaluated in this study. The study requires a 2-month patient participation.
