Hydatid disease in a thyroglossal cyst.
The location of hydatid disease in organs other than the liver and lung is unusual and occasionally producing difficulties in diagnosis. Thyroglossal cyst itself is not so common, so that more careful search of thyroglossal cyst for the presence of scolex and/or laminated membrane may result in increase in frequency of such a condition in the area where hydatid disease is prevailed. Since we were unable to find a case of hydatid disease involving thyroglossal cyst, as in our present case, we feel justified in reporting this case, considering it would be the first publication in world literature.

Prophylactic appendectomy: is it worth to be done?
There are still many controversial issues in prophylactic appendectomy. In this retrospective study, we have appraised the reasons and results of prophylactic appendectomies performed between January 1997 and August 1999. Sixty four prophylactic appendectomy cases were included in this study and all resected specimens were submitted to histopathological analysis. In 23 patients with incisional hernias, a prophylactic appendectomy was performed as, in the future, dense adhesions may lead to difficult appendectomy. Additional appendectomy had no negative effect on perioperative complications, compared with the patients without appendectomies. In conclusion, in the presence of optimal conditions, prophylactic appendectomy can be performed safely.

The influence of sphincterotomy and hepatic plexus vagotomy on ascending infections of the biliary tract: an experimental study in dogs.
BACKGROUND/AIMS: Hypertonic dyskinesia of the sphincter of Oddi is an important factor in the pathogenesis of postcholecystectomy syndrome, and this condition is usually treated by endoscopic sphincterotomy. However, it has been demonstrated that the biliary tract may also be contaminated after sphincterotomy. In various experimental studies, it has been established that the choledochal pressure decreases by a mean of 32% to 28% after hepatic plexus vagotomy. This experimental study was performed to investigate whether hepatic plexus vagotomy and/or sphincterotomy result in contamination of the biliary tract. METHODOLOGY: Thirty street dogs were divided into three equal groups. The three groups underwent simple laparotomy, transduodenal papillotomy, hepatic plexus vagotomy, respectively, and gallbladder bile samples were taken from all of them. Relaparotomy was performed after four weeks, and again, bile samples were taken from the gallbladder. All bile samples were examined microbiologically. RESULTS: Bacteria were not found in the first bile samples taken from the three groups. Bacteria were not found in the bile samples taken during the second surgery in the simple laparotomy and hepatic plexus vagotomy groups. However, both aerobic and anaerobic bacteria were found in the papillotomy group in seven of the ten dogs. CONCLUSION: These results demonstrate that hepatic plexus vagotomy decreased choledochal pressure and did not cause contamination of the biliary tract. It may be a treatment of choice to prevent postcholecystectomy syndrome resulting from sphincter of Oddi dysfunction.
