Purpose: This study was performed in order to evaluate effectiveness of controlled hypotension decreasing blood lose in transthoracic esophageal resection., Patients and Methods: Thirty-six patients were enrolled in this randomized study. The patients were divided in to two groups. We used controlled hypotension induced by thoracic epidural anaesthesia for the group T (n=18/50%). For the group K (n=18/50%) we used only endotracheal anesthesia. The median arterial pressure was about 50 mmHg in group T and 80-110 mmHg in group K. We investigated intra-operative and post-operative blood loss, the average operating time, opioid and inhaled anesthetic use and stay in intensive care unite., Results: The intra-operative blood loss was less for 45.7% in group T than in group K but post-operative blood loss was the same in groups. The mean operation time was 14.2% shorter in group T. We used 80% less fentanyl and 43% less inhaled anesthetics in group T. The stay in intensive care unit was 2.6 days in group T and 3.9 in group K. There were no significant complications caused by controlled hypotension., Conclusion: We conclude that controlled hypotension is an effective method to decrease blood loos and blood transfusions. It creates better conditions for surgery and reduces operation time. There were no serious cardiac, neurological and renal intra-operative and post-operative complications resulting from the use of controlled hypotension.

Unlabelled: Objective was to evaluate prognostic factors influencing the postoperative mortality after esophagectomy., Material and Methods: The results of surgical treatment of 106 patients suffering from esophageal cancer were analyzed retrospectively. The presurgical risk factors in the surviving patients (group I, n=94) and in those patients, who died within the postoperative period (group II, n=12), were compared. The following indicators were analyzed: patients' age, body mass index, preoperative loss of body mass, tumor location, type and duration of operation, amount of blood transfused, ECG changes, changes in the lungs visible on chest X-ray, and spirometry indices. We examined the volume of forced expiration within the first second (FEV1), forced expiratory vital capacity (FVC), peak expiratory flow (PEF), Gaensler index (FEV1/FVC), Tiffeneu index (FEV1/VC) and amount of PaCO(2)in arterial blood., Results: Postoperative mortality was 11.3%. The following statistically reliable differences in the indices of group I and group II patients were established: FEV1 (82.3% and 65.4%), Gaensler index (75.2% and 68.5%), PaCO(2)(37.4 mmHg ir 42 mmHg), radiographic changes in the lings (13.6%l and 61.2%), loss of body mass within the preoperative period (11.2% and 18.3%), lower albumin values (39.9 g/l and 30.5 g/l) and tumor localization within the upper third of the esophagus (22% and 68.8%). The leak of anastomosis - 11.8% and 82.8%., Conclusion: The postoperative mortality after esophagectomy mostly depends on the status of pulmonary function during the postoperative period, inadequate nutrition during the preoperative period and tumor localization in the upper third of the esophagus. Main complications after esophagectomy are pulmonary insufficiency and leak of anastomosis.

Unlabelled: Objective of work was to evaluate efficacy of surgery for esophageal cancer with one-step gastric pipe reconstruction, to analyze postoperative complications, causes of deaths and patient's life expectancy. In 1992-2002 in Clinic of Surgery Vilnius University Institute of Oncology 213 patients underwent surgery for esophageal cancer; 177 patients (83.0%) were applied transthoracic approach, 34 patients (15.9%) transhiatal and 2 patients (0.9%) Lewis type operations. TNM of patients were T3N1M0 - 99 (46.4%), T2N1M0 - 17 (7.9%), T2N0M0 - 16 (7.5%), T4N2M0 - 54 (25.3%), T2-3N2M1 - 27 (12.6%). Patient performance status according to WHO scale was 0-2. The following postoperative complications were observed: vagus pneumonia - 52 (24.2%) patients, heart insufficiency- 13 patients (6.1%), aortal bleeding 3 (1.4%) patients, suture leakadge - 33 (15.4%) patients, injury of n. reccurentis 17 (7.9%) patients, pleurites 29 (13.6%). Postoperative mortality after transthoracic approach - 29.3%, transhiatal - 15%, Lewis resections - 0%. Median survival after transthoracic approach - 29 months, transhiatal - 34 months, Lewis resections - 39 months., Conclusions: Surgery for esophageal cancer is the most sufficient way of esophageal cancer treatment. Three-level lymphadenectomies postpone early relapses. Postoperative mortality varies from 15 to 29.3%, median survival from 29 to 39 months.
