Cholelithiasis Clinical Trial
Official title:
The Study of Laparoscope Combined Ureteroscopic Air-pressure Ballistic Lithotripsy to Treat Patients With Hepatolithiasis
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.
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.
The experimental group performed under the situation of tracheal intubation general,placing
the ureteroscope into common bile duct and exploring the bile duct after laparoscopic
cholecystectomy and choledochotomy.Associated with air-pressure ballistic lithotripsy once
discover bile duct stones and retrieve the rubble by flowing it out.To stone's diameter
lower than 5 mm,use lithotomy forceps pull it out.Examining the bottom of common bile
duct,ensuring that it will not obstructed.Last,placing the T-tube continuous drainage the
residual stones.The control group using the way of hepatectomy.Choosing suitable surgical
options according to the stones' location and associating with choledochoenterostomy if
needed.
Contrastive analyse two groups' clinical indicators,such as operation time,blood loss during
the surgery,hospital stay,the stone clearance rate,the residual stone rate,the incidence of
postoperative complications and so on.
