Colposcopic survey of Papanicolaou test-negative cases with hyperkeratosis or parakeratosis.

A colposcopic survey was performed in 269 consecutive women with negative cytology showing hyperkeratosis or parakeratosis. A colposcopy-guided biopsy specimen of cervical abnormalities was taken in 88 cases, and human papillomavirus infection (HPV) was detected histologically in 25 cases. No cervical intraepithelial neoplasia (CIN) was detected. The detection rate of HPV was not significantly different from that observed in a consecutive series of 1073 Papanicolaou test-negative subjects self-referred for colposcopy. Colposcopic screening of subjects showing hyperkeratosis or parakeratosis with otherwise negative smears is not recommended because it does not allow detection of cytologically false-negative CIN.

Percutaneous transhepatic cholangioscopy with a 2.8 mm fiberscope.

The authors describe their initial experience with a 2.8 mm (8.5F) fiberscope. The instrument, used to refine interventional radiology maneuvers of the intra- and extra-hepatic bile ducts, caused no additional discomfort to the 18 patients treated. The fiberscope permitted differentiation between different causes of biliary stenosis in the few cases where doubt persisted after percutaneous cholangiography. Brushing was also performed wherever necessary. The color, and thus the composition, of bile duct stones could also be determined. This has helped us to plan the therapy with methyl-tert-butyl-ether (MTBE) in patients with cholesterol stones. Compared with traditional fiberscopes (diameter of 5mm or more) the new instrument is easier to use, and allows more peripheral ducts to be reached, but is expensive and has a smaller field of view and fewer possibilities for therapeutic applications.

[Percutaneous transhepatic cholangioscopy with an 8.5 French endoscopic catheter. Technic and preliminary results].

The authors describe their preliminary personal experience in bile duct endoscopy with a very small diameter catheter (8.5 F) much less traumatic than traditional choledochoscope (15 F). The CE can be reutilized after sterilization; an angiographic guide wire up to 0.042" can be introduced in the operating channel. The CE was used in 3 patients with uncertain cholangiographic diagnosis. Instrument introduction is facilitated when simple technical manoeuvres are followed; there were no difficulties in report interpretation. An experienced interventional radiologist and an endoscopist are needed to handle the instrument. Cytologic sample, biopsy and gallstone lithotomy instruments will increase diagnostic and therapeutic possibilities of the system: for this a wider CE use in the immediate future to complete interventional radiology manoeuvres can be expected.

[Clinical evaluation of chemical cholelitholysis using methyl tertiary butyl ether in lithiasis of the bile ducts].

Personal experience is reported in the treatment of calculosis of the biliary ways using MTBE and injected through percutaneous biliary drainage catheters placed surgically or endoscopically in 11 patients in whom surgery appeared to be contraindicated or particularly dangerous. In 10 out of the 11 cases chemical cholelitholysis was successful and the technique is therefore proposed as a valid alternative to surgery in ductal cholelitholysis when sphincterotomy and endoscopic removal of the stones cannot cure the conditions.

Methyl-TER-butyl ether (MTBE) and endoscopic sphincterotomy. A possible solution for dissolving gallstones.

MTBE was instilled in 6 cases of lithiasis (1 intrahepatic, 5 giant common bile duct stones following EPT). The nasobiliary route (3 cases) and a percutaneous biliary drain (3 cases) were used for this purpose. Complete stone dissolution was achieved in four cases. In the other two, volume reduction was sufficient to allow spontaneous elimination after EPT. A full clinical recovery was obtained in all cases. Further investigation is required in cases of intrahepatic and common bile duct stones when their removal by EPT is not enough to lead to clinical resolution. Follow-up is indispensable.

[Transcutaneous chemical cholelitholysis with methyl tert-butyl ether (MTBE). lst results in man].

Three patients have been treated, with instillation of MTBE through a transcutaneous biliary drainage after transduodenal sphincterotomy. The first had gallbladder stones, the second common bile duct stones and the last intrahepatic stones (V segment). While in the first case there has been only a partial success in the other two we have obtained a total dissolution of the stones, with complete clinical recovery. This treatment has not caused immediate side effects but the absence of long term damage has not yet been proven. We think that the use of MTBE is not indicated in gallbladder stone disease. Its major indication is the dissolution of ductal gallstones when transduodenal sphincterotomy and endoscopic removal of the stones have failed.

Contribution of cytology, colposcopy, target biopsy and conization to the early diagnosis of precancerous and cancerous lesions of the cervix uteri.

The study is based on 334 cytologic suspect or positive women observed in the area of Florence. Cytologic diagnoses of dysplasia, carcinoma in situ (CIS), and invasive carcinoma are related to the histologic reports. To the same histologic reports are related the colposcopic aspects. Lastly, diagnoses made by target biopsy are compared with the final diagnoses made by cone biopsy. The 3 diagnostic methods and their diagnostic accuracy are then compared. As regards dysplasia, the diagnostic precision of cytology is 40.2% and for target biopsy in 76.9%. In the diagnosis of CIS, cytology shows a diagnostic accuracy (77.7%) that is a little lower than that of target biopsy (81.7%). In invasive carcinoma, cytology has a good diagnostic precision (88.2%), which becomes 100% if the diagnosis is made by target biopsy. The correlation between colposcopic aspects and histologic reports is not very reliable. We conclude that cytology is a valid test in an extensive mass screening, that colposcopy is essential to execute target biopsy, and that the latter is useful in defining dysplasia and invasive carcinoma diagnoses. On the contrary, in the case of CIS, target biopsy does not greatly increase cytology diagnostic precision.

[Morphological studies of gastric arteries in patients with gastro-duodenal ulcer].

Microscopic lesions of the gastric arteries have been studied in 21 patients subjected to resection for gastroduodenal ulcer. The left gastric artery, particularly in patients with gastric ulcer, presents lesions to the intima and media and these can lead to obliteration of the lumen, classifiable as atherosclerotic disease. The seriousness of the lesions would seem to be independent of sex and age. In some cases gastric artery lesions were compared with those to the arterioles in the vicinity of the ulcer. At least as far as the gastric district is concerned, there would not appear to be any gravity correlation between large and small vessels. Some aspects of the vascular pathogenesis of gastroduodenal ulcer are discussed.
