[Classification, differentiated and topic diagnosis, and treatment of hepatic cystic lesions].

Accumulated in 2004-2014 yrs in Department of laparoscopic surgery and choledocholithiasis experience of treatment in patients, suffering parasitic and nonparasitic hepatic cysts, was analyzed. Own improved classification of hepatic cystic lesions was proposed. Peculiarities of performance of open operations, of the puncture miniinvasive operations and interventions for hepatic cysts, using laparoscopic approach, were enlighten. Main indications for surgical treatment of hepatic cysts were adduced, depending on their kind, size, localization and clinical signs.

[Analysis of immediate causes of mortality in the injured persons, suffering open hepatic injury on a prehospital stage].

The results of a medical help delivery on prehospital stage to 200 injured persons, suffering penetrating abdominal wounding with hepatic damage, were analyzed. The main cause of death in 87.5% of the injured persons with open hepatic damage is a non-compensated blood loss, in 12.5%--traumatic shock and a prehospital stage duration. In accordance to data of the expert estimation, the anesthesiologic adequacy have constituted in the group of survivors--80.76%, and in those, who died--68.75%, confirming a very high level of the anesthesy adequacy. Level of adequacy of the blood loss compensation have constituted in group of survivors--57.69%, and in the group of patients, who died--37.50%, what could not be considered satisfactory. In patients--survivors a conditional adequacy of application of hemostatics have constituted 76%, and in a group of the injured persons, who have died--0.

[Prognostication of efficacy of simultant laparoscopic operations in accordance to the risk estimation scale, and the method of establishing of indications and contraindications].

Experience of surgical treatment was summarized and its results were analyzed in patients, suffering biliary calculous disease, coexistent with other surgical diseases of abdominal organs. Main aspects of diagnosis and prognosis for efficacy of simultant operations were presented, and there were also adduced the method of prognosis of the operative treatment results in such patients, the proposed principle of determination of indications and contraindications for performance of simultant laparoscopic operations, a scale of the risk estimation for performance of such operative interventions.

[The trocar hernia after laparoscopic operative interventions. classification, treatment, prophylaxis].

Own experience of treatment of patients, suffering trocar hernias, occurred after laparoscopic operative interventions, was analyzed. Classification of trocar hernias was proposed, the main factors of risk and prognostic criteria of a trocar hernias formation were analyzed. The main methods of the trocar hernias correction are adduced.

[Laparoscopic surgery performed for focal liver pathology of various etiology].

The own experience on surgical treatment of more than 400 patients, suffering parasytic and nonparasitic hepatic cysts, benign and malignant hepatic tumors, using laparoscopic technologies, was summarized. Indications for laparoscopic operations, the main technical aspects, immediate and late follow-up results were analyzed. Advantages of laparoscopic operations in comparison to open operative interventions in thoroughly selected patients were noted.

[Combined laparoscopic operations in patients with acute appendicitis and biliary calculous disease].

The experience of surgical treatment was summarized in patients, suffering an acute appendicitis, in whom simultaneously a biliary calculous disease was revealed. The procedure and technical aspects of performance of simultant laparoscoplic operation were depicted, the indications and contraindications for simultant operation conduction were determined, a consequence of the operative stages performance was determined. The main advantages of simultant laparoscopic operations were proved and the results of treatment analyzed.

[Simultaneous laparoscopic operations for biliary calculous disease, inflammatory and cystic diseases of abdominal organs].

The results of treatment in patients, in whom biliary calculous disease and inflammatory and cystic diseases of abdominal organs were diagnosed simultaneously, were analyzed. Main aspects of diagnosis and prognostication of efficacy of simultant operations conduction, technical rules of surgical interventions were presented. In such patients there were elaborated indications for performance of simultant completely laparoscopic and laparoscopic combined operations.

[Simultant laparoscopic operations for biliary calculi disease and hernia of the anterior abdominal wall].

The results of treatment of patients, in whom biliocalculous disease and hernia of anterior abdominal wall were diagnosed, were analyzed. The main aspects of diagnosis and prognosis of simultant operations in such patients, some technical procedures of operative interventions were depicted. Indications for performance of simultant completely laparoscopic and simultant laparoscopic combined operations in these patients were determined.

[Estimation of endosonography method in the patients with moderate risk for choledocholithiasis].

Efficacy of endoultrasonography application in conditions of moderate risk for choledocholithiasis occurrence was estimated in 33 patients, in whom ultrasonography (US) did not reveal the common biliary duct concrements. Sensitivity, specificity, accuracy, positive and negative prognostic values of the method in suspicion for choledocholithiasis presence while US performance have had constituted 78.6, 94.7, 82.0, 98.2 and 54.5%; vs for endoultrasonography--100, 94.4, 97, 93.8 and 100% accordingly. Endoultrasonography constitutes a safe and highly effective method of investigation in patients in suspicion of the biliary ducts disease presence, it permits to reveal choledocholithiasis in significant part of patients after ineffective US. This diagnostic option permits to reduce the need for performance of diagnostic endoscopic retrograde cholangiopancreaticography.

[Simultant laparoscopic operative interventions for cholelithic disease].

Experience of simultant laparoscopic operations was analyzed. The main diagnostic aspects were determined in patients with concomitant pathology of abdominal organs, retrospective analysis of the results obtained was conducted. There was elaborated algorithm of a surgeon activities while doing intraoperative diagnosis of concomitant surgical diseases, which may be eliminated by the usage of simultant operative intervention.
