[The comparative analysis of laparoscopic and minilaparotomic techniques in emergency abdominal surgery].

Owing the experience of 16 101 miniinvasive operations by acute diseases of the abdominal cavity, the authors pose that the introduction of polytechnological methods has certain perspectives. The combination of different methods with the use of modern technologies lead to better results.

[Technical classification of minimally invasive operations].

9167 minimally invasive operative procedures performed in a single institute during 1993-2007yy. were analyzed. A worked out classification, based on a predominantly used surgical technique, was suggested.

[Methodological and technological aspects of relaparoscopy].

Overall 3457 laparoscopic procedures after open and laparoscopic abdominal operations have been performed including 270 relaparoscopies due to intraabdominal postoperative complications. Basing on their own experience, the authors give methodological and technological recommendations allowing to increase diagnostic and surgical efficacy of relaparoscopy and to reduce the rate of complications.

[Endoscopic sclerotherapy of esophageal varicose veins in portal hypertension].

The results of endoscopic sclerotherapy (EST) in the patients with portal hypertension (PH) are analyzed. Efficacy of methods in the treatment of gastroesophageal varicosity in urgent situations (bleeding) and "cold" period was evaluated. Schemes of staged minimally-invasive surgical correction of PH syndrome are described.
