Laparoscopic treatment of gallbladder duplication. A plea for removal of both gallbladders.

BACKGROUND: Gallbladder duplication is a rare congenital condition, which can now be detected preoperatively by imaging studies. METHODS: We report a case of duplicated gallbladder with symptomatic unilobar gallstones. Appropriate biliary workup (ultrasound, oral cholecystography, and intravenous cholangiography) allowed a correct preoperative diagnosis. RESULTS: Laparoscopic treatment included selective removal of the diseased accessory gallbladder. However, postoperative acute cholecystitis and symptomatic gallstone occurred in the remaining main gallbladder, and laparoscopic reintervention was required 27 months later. CONCLUSIONS: This case illustrates the need for complete removal of both gallbladders during initial surgery. Precise intraoperative recognition of vascular and biliary anatomy-including abnormalities-is highlighted to avoid mistakes during surgery.

Posttraumatic intra-gallbladder hemorrhage in a patient with liver cirrhosis.

We report a case of intra-gallbladder hemorrhage secondary to blunt abdominal trauma in a patient with liver cirrhosis. A 58-year-old man was admitted to a local hospital with persistent right upper quadrant abdominal pain. Anemia was detected, and computed tomography (CT) revealed a high-density mass in the gallbladder lumen. He was transferred to our hospital because a gallbladder tumor was suspected. He had a history of habitual alcohol abuse and had sustained blunt abdominal trauma in the right upper quadrant 29 days before admission to our hospital (4 days before to the admission local hospital). The intra-gallbladder high-density mass depicted on the CT scan, observed as non-shadowing low-level echoes, was deemed to represent a blood clot on ultrasonography (US) performed 31 days after the trauma. US-guided percutaneous transhepatic gallbladder aspiration and cholecystography confirmed the presence of an old blood clot in the lumen. Because of the patient's persistent pain, a cholecystectomy was performed. The distended gallbladder was filled with old clotted blood.

Disease of the gallbladder in patients with normal cholecystograms.

In contrast with what has widely been assumed, disease of the gallbladder sometimes remains undertected by even repeated cholecystography or cholegraphy. Chronic cholecystitis, gallstones, and acalculous cholesterolosis can escape detection by roentgenography of the gallbladder. Of 4,000 patients subjected to cholecystectomy between 1962 and 1973, the cholecystogram had been normal in only two. The range of indications for the operation has since been widened. Patients with typical symptons of gallbladder disease or recurrent pancreatitis of unknown origin have been operated on despite a normal cholecystogram. Within as short a period as eight months, an additional six patients with a normal cholecstogram have been operated on at our hospitals. Treatment consisted of cholecystectomy also in the four patients in whom no stones could be palpated in the gallbladder. Gross and microscopic examination of the gallbladder in these patients revealed cholesterolosis. When last seen, seven of the eight patients were still symptom-free an average fifteen months after the operation.

Detection of occult gallbladder disease by duodenal drainage.

Examination of gallbladder bile in the sediment of duodenal drainage obtained after magnesium sulfate stimulation was used to evaluate the presence or absence of gallbladder disease in thirty-four patients with symptoms suggestive of cholecystitis and normal or equivocal oral cholecystography. Ten patients had positive tests and nine of these had cholecystectomy. All nine had pathologically confirmed cholecystitis and seven of nine had cholelithiasis. Three patients with negative test results had laparotomy and normal gallbladders. The remaining twenty-one patients with negative tests have been followed up to three years, and none have returned with evidence of biliary tract disease. The results of this study suggest that duodenal drainage (Meltzer-Lyon test) is a valuable adjunctive diagnostic study in patients with gallbladder disease symptoms in whom normal or equivocal oral cholecystograms are obtained.

Prostaglandins in chronic cholecystitis.

Prostaglandin-like material was extracted from the mucosa and muscle wall of chronically inflamed human gallbladders. Bioassays showed that "synthesised" levels were 3-5 times corresponding "basal" levels, indicating that both mucosa and muscle wall can synthesise PG-like substances, and that indomethacin (10 mug/ml) inhibited this synthesis. Mucosal PG levels were higher in gallbladders with multiple gallstones than with a solitary stone, and overall the mean PG level in mucosa was 12-13 times higher than in the muscle wall. Chromatography of mucosal extracts showed substances indistinguishable from primary PGE and F compounds together with a PGD2-like component. An attempt has been made to relate these findings to the degree of chronic inflammatory cell infiltration and to radiological visualisation at pre-operative cholecystography.

Radiographic features of oral cholecystograms of 448 symptomatic gallstone patients: implications for nonsurgical therapy.

Since radiographic findings on oral cholecystography (OCG) have implications for the eligibility for nonsurgical therapy of elderly patients, we investigated the OCGs of 448 symptomatic gallstone patients (109 male, 339 female; mean age, 49.8 +/- 14 (range, 21-88)). Opacification of the gallbladder was found in 323 cases (72.1%). Calcifications of gallstones were found in 85 opacified gallbladders (26.3%). Solitary and multiple stones were calcified in 35.3% and 18.2%, respectively (P < 0.0005). When divided into two groups (< or = 40 years and > 40 years), there was a significant increase in calcifications (P < 0.02) and a non-significant increase in opacification with increasing age. It is concluded that age is a determinant for calcification of gallstones and not opacification of the gallbladder. Since multiple stones are proportionately observed more in clinical studies than in epidemiologic studies, it is suggested that multiplicity of stones predisposes to biliary complaints. That solitary stones are more likely to be calcified than multiple stones, adds to the hypothesis that solitary and multiple stones have a different pathogenesis. Elderly patients, in whom non-surgical therapy is most likely to be indicated and cost-effective, are less likely to be suitable for this form of treatment, since age is a determinant for stone calcification.

Oral and contact dissolution of gallstones.

The appropriate selection of patients for treatment with oral ursodeoxycholic acid (UDCA)--a drug that has virtually no side effects--results in about 50% of patients experiencing safe dissolution of gallstones within 2 years. Eligible patients have small (less than 20 mm in diameter) radiolucent gallstones in a gallbladder visualized by oral cholecystography (OCG); ideal candidates are thin women who have gallstones that are less than 15 mm in diameter, floating when observed by OCG, or of low density on computed tomographic (CT) scanning. Contact dissolution with methyl tert-butyl ether (MTBE) is rapid, effective more often than UDCA, and safe but requires the expertise of an interventional radiologist. Any size and number of cholesterol gallstones that are not CT-dense will be dissolved by MTBE, leaving at most only insoluble debris that is clinically innocuous. Although gallstones recur after dissolution by UDCA or MTBE in 50% of patients within 5 years, recurrent gallstones are usually asymptomatic and/or can probably be dissolved. We conclude that oral or contact dissolution provides an alternative treatment to cholecystectomy for about 30% of patients with symptomatic gallstones.

The value of ultrasound in predicting non-visualization of the gall-bladder on OCG: implications for imaging strategies in patient selection for non-surgical therapy of gallstones.

Gall-bladder visualization on oral cholecystography (OCG) is required for most non-surgical therapies of gallstones. In this study we attempted to establish sonographic criteria which will predict non-visualization of the gall-bladder on OCG. For this purpose we compared the results of ultrasound (US) and OCG in 171 patients with gallstones being assessed for non-surgical therapy. Sonographic criteria for non-visualization were a contracted gall-bladder and stone impaction in the gall-bladder neck or cystic duct. In detecting findings which predict non-visualization on OCG, US had a sensitivity of 78.3% and a specificity of 97.6%. The predictive values were: positive findings 92.3% and negative findings 92.4%. The overall accuracy was 92.4%. We conclude that US can be used as a first step in selecting patients for non-surgical therapy and if US indicates a contracted gall-bladder, 11% of the patients can be excluded from further diagnostic imaging.

Chronic cholecystitis and the oral cholecystogram.

Gallbladder image density at oral cholecystography has been compared with histological grading of the severity of chronic cholecystitis in resulting cholecystectomy specimens. (i) There was a linear relationship between gallbladder opacification and the grade of chronic cholecystitis. (ii) Removal of patients with either non-opacified gallbladders or abnormal liver function did not alter the linear trend. (iii) The occurrence of gallstones was independent of the degree of gallbladder opacification. (iv) The presence of gallstones did not correlate with the severity of chronic cholecystitis. A standardised oral cholecystographic technique with a grading system for gallbladder image density can be used as an index of the severity of chronic cholecystitis.

Hepatic imaging with radiology and ultrasound.

Radiographically, the diseased liver may change in size, shape, position, or opacity. Contrast studies such as peritoneography, cholecystography, portography, and arteriography may be performed to increase the specificity of the radiographic diagnosis. Ultrasound can be used to detect the changes in liver echogenicity associated with disease, identify focal verses diffuse disease processes, detect vascular and biliary abnormalities noninvasively, and direct needle aspirates and biopsies for culture, cytology, and histopathology.

[Iodine-induced hyperthyroidism due to contrast media (author's transl)].

A prospective study in an area with endemic goitre showed 18 patients (15.1%) out of 119 investigated with iodine containing contrast media to be hyperthyroid after 28 days. Oral cholecystography led to the highest (27.9%) and infusion urography to the lowest (5.3%) rate of hyperthyroidism. Determination of the serum concentration of thyroxine, triiodothyronine, basal and stimulated thyrotropine is not a suitable method to detect the risk for hormonally euthyroid patients before a contrast media investigation.

[Ultrasound diagnosis of cholelithiasis: comparison with radiological studies (author's transl)].

Results of ultrasonic anc cholecystographic (oral or intravenous) gall-bladder studies were compared retrospectively. 302 radiological studies of the gall-bladder, 156 oral and 146 intravenous cholecystograms, had been performed on 223 patients tested by ultrasound within six months. The gall-bladder was visualised by ultrasound in 217 (97.3%), in the intravenous cholecystogram in 92 of 146 (63%) and the oral cholecystogram in 82 of 156 (53%). The diagnosis of cholelithiasis by ultrasound was made in 97 of 223 cases, confirmed in 96 by further studies or operation. There was only one false-positive result. 143 radiological studies in these 97 patients gave 87 negative cholecystograms, gall-stones being directly demonstrated radiologically in only 46. There was one false-positive intravenous cholecystogram. In a further 97 patients ultrasound studies failed to demonstrate any gall-bladder disease, but in three of them radiology demonstrated stone (2.9% false-negative results). Amond 49 normal intravenous cholecysto-cholangiograms 47 were confirmed; once the diagnosis was made by ultrasound and at surgery (2% false-negative results). Oral cholecystography was the least reliable study. In every fourth negative test ultrasound and intravenous contrast-medium injection demonstrated a normal gall-bladder (28% false-positive).

[The segmental form of adenomyomatosis of the gallbladder in the roentgen image and sonogram].

Case report of a 58-year-old patient, whose sonogram showed a segmental narrowing and thickening of the gallbladder wall. It was possible only by means of an intravenous cholecystography revealing the Rokitansy-Aschoff-sinus, to make the diagnosis of segmental adenomyomatosis. The criteria for the diagnosis of adenomyomatosis by sonogram as compared to x-ray are described.

[Glucagon as an adjuvant to infusion cholecysto-cholangiography].

The effect of glucagon on the results of intravenous cholangio-cholecystography (IVC) was studied in a randomised trial on 246 patients. The injection of 1 mg. glucagon increased the speed of contrast excretion from the liver. This led to a significantly quicker demonstration of the gallbladder, with a tendency to more rapid filling of the biliary ducts. In patients with hyperbilirubinaemia there were somewhat fewer negative cholangiograms and significantly fewer negative cholecystograms. Considering the patients as a whole, the use of glucagon has the advantage of reducing the time taken for the examination and of a reduction of negative IVCs. Since glucagon has practically no side effects, our experience suggests that it can be recommended as an adjuvant to IVC. Improvements in IVCs are particularly significant since they are now only used for special indications.

Gallbladder disease. Prevalence in a South Wales industrial town.

In a weighted random sample of the specially enumerated population of a South Wales industrial town, examined by cholecystography for gallstones, the overall prevalence rates were 6.2 per cent for men 45 to 69 years of age and 12.1 per cent for women of the same ages. Contrary to our expectation there was no marked increase in prevalence with age in either sex. Symptoms of dyspepsia said to be suggestive of gallstones were found with approximately equal frequency in those with and without gallbladder disease.

Abnormalities in gallbladder morphology and function in patients with cholelithiasis.

Thirty-seven symptomatic cholelithiasis patients who had cholecystectomy were studied to determine the relationships between clinical manifestations, histologic findings and gallbladder absorptive capability. A clinical score was calculated from clinical data which we thought might be predictive of abnormal gallbladder histology. Histologic parameters indicative of gallbladder disease were used to calculate a histologic score. Shortcircuit current measurements, which reflect gallbladder sodium absorption,were used to assess absorptive function. Patients with very high clinical scores, indicative of pronounced clinical score was not predictive of histologic findings or absorptive function of the gallbladder is directly related to the degree of histologic abnormality, and that absorptive capability is not an all-or-none phenomenon. The data also show that visualization on oral cholecystography is an unreliable measure of gallbladder absorptive capability.

Reliability of pre- and intraoperative tests for biliary lithiasis.

The records of 242 patients, operated consecutively for biliary lithiasis, were analyzed to determine the reliability of oral cholecystography (OCG), ultrasonography (US), and HIDA in detecting biliary calculi. Preoperative interpretations were correlated to operative findings. OCG obtained in 138 patients was accurate in 92%. US obtained in 150 was correct in 89%. The accuracy of HIDA was 92% in acute and 78% in chronic cholecystitis. Intraoperative cholangiography (IOC) done in 173 patients indicated the need for exploratory choledochotomy in 24; 21 had choledocholithiasis. These observations suggest that OCG and US are very accurate, but not infallible, in detecting cholelithiasis. US should be done first; when doubt persists, the addition of OCG allows the preoperative diagnosis of gallstones in 97% of the cases. HIDA is highly accurate but not infallible in detecting acute calculous cholecystitis. IOC is very reliable in detecting choledocholithiasis; thus, its routine is justifiable.

Kinevac (sincalide for injection)/Squibb Diagnostics.

Sincalide is a rapid-acting, synthetic analog of cholecystokinin for intravenous use in postevacuation cholecystography. Serious reactions to sincalide have not been reported. The intravenous administration of sincalide causes a prompt contraction of the gallbladder as compared to the stimulus of a fatty meal which causes progressive contraction that becomes maximal in about 40 minutes. The use of Kinevac to accelerate the transit time through the small bowel decreases the time and extent of radiation associated with fluoroscopy and length of the x-ray examination of the intestinal tract. Duodenal aspiration obtained after the administration of Kinevac provides a sample of concentrated bile for analysis of cholesterol, bile salts, phospholipids and crystals. When used in conjunction with secretin to stimulate pancreatic secretion, an aspirate is readily obtained for analysis of enzyme activity, composition and cytology. As the development of endoscopic manometry affords a modality to measure and record sphincter of Oddi pressures, the paradoxical responses noted to the intravenous administration of CCK during manometric evaluation supports the diagnostic value of Kinevac used as a provocative agent in the evaluation of biliary dyskinesia.
