ABSTRACT
Objective To discuss the treatment method and opportunity for patients with gallbladder stones and extrahepatic bile duct stones who failed endoscopic removal of common bile duct stones by endoscopic retrograde cholangiopancreaticography (ERCP). Methods 12 patients, with gallbladder stones and extrahepatic bile duct stones, failed endoscopic stone extraction (ESE), underwent emergency one-stage laparoscopic cholecystectomy (LC) and Laparoscopic common bile duct exploration (LCBDE). Results All of the patients were successfully completed LC +LCBDE and stones were completely removed. Hyperamylasemia occurred in 3 cases and there was no bile leakage, intestinal leakage, cholangitis, pancreatitis, biliary bleeding and other complications. Conclusions Emergency LCBDE has been shown to be a safe and effective salvage procedure for failed ESE.
ABSTRACT
Objective To observe the characteristics of electromyography of sphincter of Oddi (SO) in patients with cholelithiasis after common bile duct exploration,and investigate new methods for detecting the motility of SO.Methods The basal pressure of SO(SOBP)and electromyography of SO were detected in 33 patients with cholelithiasis who were reexamined at the Southwest Hospital from January to October,2010.All patients were divided into low SOBP group,normal SOBP group and high SOBP group.The amplitude,frequency and duration of SO spike burst(SOSB)of the three groups were compared.Results The numbers of patients in the low SOBP group,normal SOBP group and high SOBP group were 14,13 and 6,respectively.The mean SOBP of the low SOBP group,normal SOBP group and high SOBP group were(3.1±1.2),(18.5±7.6),(39.8±4.8)mm Hg (1 mm Hg=0.133 kPa).The amplitude,frequency and duration of SOSB were(41±27)μV,(5.8±1.6) times/minutes and(2.7±0.6)s in the low SOBP group,and(150±71)μV,(6.9±1.4)times/minutes and (3.4±0.7)s in the normal SOBP group,and(301±109)μV,(7.8±1.2)times/minutes and(4.2±0.7)s in the high SOBP group,respectively,with significant difference among the three groups(F=50.751,4.293,13.159,P<0.05).Conclusion The results of electromyography of SO could reflect the function of SO,and it is possible to be a prospective method in the clinical research of SO.
