Details of teaching, learning and training in laparoscopic surgery.

The authors discuss the specific details of teaching, learning and training in laparoscopy in 6 main sections, on the basis of their experience gained through basic and advanced courses held for approximately 480 participants at the courses organised at the Department of Experimental Surgery of the University Medical School of Debrecen, between 1989 and 1996. The 6 section cover the following: 1. Why these courses are needed? 2. Who should participate in them? 3. When courses should be held (continuously for beginners, at an appointed time for advanced participants, and chances for training should be provided at any time, according to demand) 4. What should be taught? 5. Where teaching and training should take place (surgical learning/training centres) and 6. What methods of teaching should be used.

Free radical reactions in the gallbladder.

The changes in the composition of bile can lead to the process of it's crystallization in the gallbladder. In bile model it was shown that inflammation with the generation of reactive oxygen metabolites may induce and influence the cholesterol monohydrate crystal formation within supersaturated bile. The aim of this study was to investigate the ability to detect traces of reactive oxygen metabolites, thiobarbituric acid reactive compounds and dien, in order to compare cholesterol and bilirubin contents in bile and serum during different conditions of inflammation in the gallbladder's wall. In every bile sample a reference to free radical reaction was found. There was an increase in MDA during higher degree of inflammation in the gallbladder, but no alteration in the dien content was observed. In case of common bile duct stones the bilirubin in the serum and in the gallbladder was parallelly high, but in other cases there were no significant correlation. In an occluded gallbladder with hydrops the content of protein was significantly higher in 85% of the cholesterol stones. As a conclusion, free radical reactions in the wall of gallbladder as well as in bile can induce gallstone formation. Further studies are needed to clarify the time which is sufficient to change the composition of bile and the degree of inflammation which lead to the onset of stone formation.

Bile duct injuries in the era of laparoscopic cholecystectomy.

By the introduction of laparoscopic cholecystectomy a new field of surgical development has been opened, resulting in the reduction of conventional surgical trauma, and giving the chance to the patient seeking for less postoperative pain, short hospital stay and quick return to activity and work. In spite of these advantages, many laparoscopic cholecystectomy related complications occurred, especially in the period of the learning curve. Due to the special technical requirements, problems of the two dimensional vision, depth perception and hand-eye coordination guided to injuries of the bile ducts, which reached a high rate of 3%. This rate is ten times more when compared with conventional cholecystectomy. The authors present a detailed account of the causes of the injuries, their typical localisation and the best way to avoid and treat them.
