  Purpose
Timing of laparoscopic cholecystectomy following after endoscopic retrograde cholangiography for acute biliary pancreatitis is a controversial issue. There are still many confounding findings offering either early laparoscopic cholecystectomy within 72 hours following endoscopic sphincterotomy or delayed surgery after 6 weeks. Peritoneal plasmin system is known to be an important factor in peritoneal healing and adhesion formation. Measurement of tissue concentrations of tissue-type plasminogen activator and its specific activity, urokinase-type plasminogen activator, and plasminogen activator inhibitor type 1 are thought to be helpful to show peritoneal adhesions after endoscopic sphincterotomy.

Condition Intervention Phase
Cholelithiasis Associated With Common Bile Duct Stones Other: tissue sampling from peritoneum of the gallbladder Early Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: Prospective Randomized Clinical Study for Timing of Laparoscopic Cholecystectomy After Endoscopic Retrograde Cholangiography for Acute Biliary Pancreatitis

Primary Outcome Measures:
  • measurement of peritoneal fibrinolytic response following endoscopic retrograde cholangiography [ Time Frame: six months ]
    measurement of tissue concentrations of tissue-type plasminogen activator and its specific activity, urokinase-type plasminogen activator , and plasminogen activator inhibitor type 1


Secondary Outcome Measures:
  • surgical outcomes of laparoscopic cholecystectomy following endoscopic retrograde cholangiography [ Time Frame: six months ]
    evaluation of surgical outcomes including operating time, morbidity and mortality of laparoscopic cholecystectomy


Enrollment: 60
Study Start Date: September 2012
Estimated Study Completion Date: August 2015
Estimated Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: activity of peritoneal fibrinolysis
measurements of peritoneal fibrinolysis using tissue-type plasminogen activator and its specific activity, urokinase-type plasminogen activator, and plasminogen activator inhibitor type 1
Other: tissue sampling from peritoneum of the gallbladder
tissue sampling from peritoneum of the gallbladder during laparoscopic cholecystectomy after an acute attack of acute biliary pancreatitis
Active Comparator: surgical outcomes
surgical outcomes of laparoscopic cholecystectomy
Other: tissue sampling from peritoneum of the gallbladder
tissue sampling from peritoneum of the gallbladder during laparoscopic cholecystectomy after an acute attack of acute biliary pancreatitis

Detailed Description:

Peritoneal fibrinolysis is crucial in peritoneal healing processes and subsequent adhesion formation. It is expected that endoscopic retrograde cholangiography is a trauma causing adhesions around the hepatobiliary area. Such adhesions may cause some difficulty for consequent gallbladder surgery. For that reason, tissue measurements of factors indicating degree of peritoneal healing and adhesion is helpful for timing of such surgical interventions.

Patients are going to be randomized to early and delayed surgery groups. Sampling of peritoneum around the gallbladder during laparoscopic cholecystectomy in patients after endoscopic retrograde cholangiography is performed. Tissue concentrations of tissue-type plasminogen activator and its specific activity, urokinase-type plasminogen activator, and plasminogen activator inhibitor type 1 are going to be studied by using commercial assays.

Peritoneal fibrinolytic activity and surgical outcomes are going to be compared.
