Technetium-99m-pyridoxylideneglutamate (99mTc-PG) is a nontoxic radiopharmaceutical that was found to undergo rapid biliary excretion in normal humans. The biliary tree and gallbladder were seen within 10-15 min of injection and by 20 min marked accumulation of radioactivity was noted in the gallbladder and gastrointestinal tract. Of ten "control" volunteers, seven had normal 99mTc-PG-cholescintigrams. In the remaining three, the gallbladder was not visualized. Gallbladder disease was not excluded in these three subjects. Of 24 patients referred for investigation of right upper quadrant abdominal pain, 13 proved to have gallbladder disease. All seven patients with acute cholecystitis and one of four patients with chronic cholecystitis had nonvisualization of the gallbladder on the cholescintigram whereas five patients with chronic cholecystitis or cholesterolosis had normal cholescintigrams. Six of the eight patients with nonvisualization of the gallbladder on cholescintigram had contrast radiologic studies (oral cholecystogram or intravenous cholangiogram or both), and in all six, nonvisualization of the gallbladder was also reported on the contrast study. cholescintigraphy was found to be greatly inferior to contrast radiologic studies in the detection of gallbladder stones. Eleven patients had complete extrahepatic biliary obstruction and this diagnosis was correctly made in all 11 by the cholescintigram. Fourteen patients had incomplete extrahepatic biliary obstruction. The correct diagnosis was made on the cholescintigram in seven but in the remaining seven it was not possible to distinguish between incomplete extrahepatic biliary obstruction and hepatocellular disease. Malignant lesions (carcinomas of head of pancreas, gallbladder, common bile duct or ampulla of Vater) were the cause of obstruction in 10 of the 25 patients with complete or incomplete obstruction and the diagnosis of obstruction due to malignancy was correctly made in 8 of these 10 by means of a scintigraphic equivalent to Courvoisier's sing. Finally, 11 patients had hepatocellular disease and a nonspecific pattern consistent with either imcomplete biliary obstruction or hepatocellular disease was observed on the cholescintigram in all 11. The 99mTc-PG cholescintigram is suggested for a role complementary to that of contrast radiologic studies in the preoperative investigation of patients with possible surgical disease of the biliary tract. Contrast radiologic techniques are advocated as being more appropriate in the nonjaundiced patient with suspected gallbladder disease whereas the 99mTc-PG cholescintigram is advocated as being more appropriate in the patient with jaundice. The value of the 99mTc-PG cholescintigram lies in the confidence with which complete extrahepatic biliary obstruction can be diagnosed. The "scintigraphic Courvoisier's sign" seems a useful indicator of malignant obstruction.

"Stenosing papillitis" is a descriptive term for an anatomic deformity of the papilla of Vater that is characterized by narrowing of the lower end of the bile duct and the proximal end of the duct of Wirsung. The defect is secondary to inflammation and fibrosis from the chronic passage of gallstones, episodes of acute pancreatitis, chronic pancreatitis, sclerosing cholangitis, peptic ulcer disease, and cholesterolosis. Patients with papillary stenosis from gallstones may present with episodes of severe upper-abdominal pain several years after cholecystectomy. The pain is often incapacitating, and patients are often addicted to narcotic analgesics. The work-up includes abdominal ultrasonography and CT scanning and endoscopic retrograde cholangiopancreatography even though the findings usually are normal. Liver and pancreatic enzymes are not frequently elevated with the painful episodes. Transendoscopic manometry may reveal elevated pressures within the papillary portion of the distal bile duct. Some patients are relieved of their pain by transduodenal sphincteroplasty and transampullary septectomy, thereby ablating the sphincter of Oddi around the bile and pancreatic ducts and enlarging their openings.

Ninety-two patients underwent a transduodenal sphincteroplasty and transampullary septectomy (extended papilloplasty) for chronic, incapacitating upper abdominal pain over an 11-year period. Seventy-nine had a prior cholecystectomy; 42 of 56 patients with reported pathology had documented gallstone disease. Serious morbidity included two moderately severe cases of postoperative pancreatitis and a pulmonary embolus. There were no deaths. Operative findings revealed stenosing papillitis (n = 45), transampullary septitis (n = 40), and papillary dysfunction (n = 7). Histologic examination of septal biopsy specimens revealed inflammation in 34 cases and fibrosis in 19 cases. There were no microscopic abnormalities in 39 biopsy specimens. The results at 1 to 10 years in 83 patients is as follows: good in 36 patients (no pain--43%), fair in 27 patients (occasional pain--33%), and poor in 20 patients (unrelieved by the procedure--24%). Patients with prior sphincteroplasty (12 of 15 with a fair to good result) benefitted the most from the procedure. Those who underwent concomitant cholecystectomy responded poorly. Risk factors for failure include alcoholism, drug addiction, mental illness, and duodenal ulcer disease. The finding of papillary cholesterolosis at operation also was accompanied by a less than optimal result. Transduodenal sphincteroplasty with transampullary septectomy provides long-term benefit to carefully selected patients with chronic abdominal pain after cholecystectomy.

Polypoid lesions of the gallbladder (PLGs) are often incidentally identified during ultrasonographic examination of abdominal pain. The present study was designed to determine the reliability of ultrasonography (US) in the diagnosis of PLGs. The records of 853 patients who underwent laparoscopic cholecystectomy (LC) for PLGs in Gazi Medical School from January 2000 to January 2004 were reviewed. Data were collected regarding the patients' gender, age, symptoms, serum lipid levels, the size and the number of polyps on US, surgical indications for PLGs and histopathological diagnosis. In all, 56 of 853 patients had PLGs and underwent LC. Right upper quadrant pain (59%) was the most common presenting symptom that led to gallbladder US. Nearly 75% of the lesions were smaller than 10 mm. At histopathologic examination cholesterolosis was found in 17 of 56 (30%) patients, and 12 of 56 (21%) demonstrated only cholelithiasis; 17 (30%) patients had both cholesterolosis and stones. Only 10 (18%) patients had adenomatous polyp and 8 of these polyps were larger than 1 cm. Overall US-based diagnosis of gallbladder polyp was inaccurate in 82%. The sensitivity and specificity of US for polyps <1 cm was 20% and 95.1%, respectively, whereas the sensitivity and specificity of US for polyps >1 cm was 80% and 99.3%, respectively. The accuracy of US in diagnosing PLGs was poor, especially in polyps <1 cm.

Acute pancreatitis is an inflammatory condition of the pancreas manifesting with abdominal pain and elevated serum levels of pancreatic enzymes. Gallstones and chronic alcohol use are the most commonly described causes. A less studied cause is cholesterolosis, gallbladder polyps that cause mechanical obstruction of the sphincter of Oddi. Here, we present the case of a 55-year-old woman who presented with acute pancreatitis and was found to have cholesterol polyps in her gallbladder with no evidence of gallstones. The patient underwent cholecystectomy with complete resolution of her symptoms.

We present a 22-year-old pregnant woman at 15 weeks of gestation, with abdominal pain and vomiting. We demonstrate that diagnosis and treatment of vomiting and abdominal pain in pregnancy can be difficult. Therefore, involvement of other medical specialists is important when common treatments fail. Cholesterolosis can cause symptoms similar to those caused by cholelithiasis. Controversial to gallstones, identification of cholesterolosis by ultrasound is hard. Cholecystectomy is the only effective treatment option for cholesterolosis and can be performed safely during pregnancy. Cholecystectomy in pregnancy should be considered if, despite atypical symptoms, gallbladder disease is suspected and other diagnoses are ruled out. This may reduce recurrent symptoms, hospital admissions, exposure to harmful drugs and obstetric complications.
