Brief Summary

Pancreaticobiliary reflux has been found in patients with cholelithiasis and gallbladder cancer associated with normal pancreaticobiliary union. However, the presence of pancreaticobiliary reflux has not been studied in patients without gallstones (healthy gallbladders). The authors believe that pancreaticobiliary reflux might be a normal phenomenon in patients with and without gallstones, although in patients with cholelithiasis it might constitute a pathological condition associated with dismotility of the biliary tree and the sphincter of Oddi.

Outcome Measures

Primary Outcomes (1)

  • Amylase and Lipase Values in Gallbladder Bile

    Normal values of lipase and amylase in gallbladder bile should be zero

    24 hours

Secondary Outcomes (4)

  • Amylase and Lipase Values in Normal Gallbladders

    24 hours

  • Amylase and Lipase Values in Gallbladders With Cholelithiasis

    24 hours

  • Normal Operative Cholangiography

    24 hours

  • Normal Preoperative Serum Values of Amylase and Lipase

    24 hours

Study Arms (2)

Normal Gallbladder

Patients with normal gallbladder (without gallstones) evidenced by preoperative ultrasonography (and postoperative biopsy) submitted to elective gastroesophageal surgery (gastrectomy for gastric cancer, bariatric surgery or esophageal surgery such as Nissen plicature or miotomy for achalasia). The pancreaticobiliary junction must be normal as evidenced by intraoperative cholangiography. Preoperative values of amylase and lipase must be normal.

Procedure: Gallbladder bile sampling and intraoperative cholangiography

Gallbladder with gallstones

Patients submitted to elective cholecystectomy for diseased gallbladders (gallbladder with gallstones evidenced by preoperative ultrasound). The pancreaticobiliary junction must be normal as evidenced by intraoperative cholangiography and the preoperative amylase and lipase levels must also be normal.

Procedure: Gallbladder bile sampling and intraoperative cholangiography

Interventions

Interventions were exactly similar for both groups, and that is how it was intended to be: Gallbladder bile sampling: Sample 5 cc of gallbladder bile after the cystic duct has been clipped or ligated. Intraoperative cholangiography: Perform cholangiography before the cholecystectomy is finished
