Experimental research and surgery: why, how, and when?

Experimental research faces two great problems: the significant reduction of public funding and the firm opposition of the public opinion. The law forbids the use of large animals, so that it is possible to use small animals only, which require microsurgical techniques. However, even a skillful surgeon does not know how to perform microsurgery and has to begin a long and tiring training to master techniques.

[Advantages of reabsorbable intradermal sutures in general surgery. Experience on 201 sutures].

Surgical wound suture is often considered of minor importance compared to the whole surgical operation. The aesthetical result of a wound suture is still hardly considered in general surgical practice compared to other "traditional" wound sutures. The Authors carried a prospective study an 201 intradermal absorbable sutures in clean general surgery.

[Benign tumors of the liver].

Diagnostic and therapeutic findings of benign hepatic tumors are analysed. In particularly the authors describe the more frequent tumors such as angioma, adenoma and FNH, but also give a guidelines on how to approach less frequent lesions.

Endoscopic ultrasonography in a case of gastric leiomyoblastoma.

Endoscopic ultrasonographic diagnosis of a gastric leiomyoblastoma stemming from the gastric wall is reported. Transparietal echography and CT had indicated that this tumor arose form the right ovary.

DDD pacemakers maximize hemodynamic benefits and minimize complications for most patients.

A 44-month retrospective analysis was performed on 666 pacemakers implanted at Mt. Sinai Medical Center. Mapping techniques and endocardial waveform analyses were used during lead positioning to ensure the best electrical environment.

Pacemaker clinic evaluations: key to early identification of surgical problems.

The pacemaker center evaluation was responsible for the timely reoperation of 341 pacemaker patients over the last three years. The most common indication for reoperation was battery end-of-service (46.3%).
