Prognostic Model for Vasopressor Requirement After Retroperitoneal Adrenalectomy for Pheochromocytoma: A Retrospective Study.

Objectives: To evaluate the risk factors for postoperative vasopressor requirement among patients with pheochromocytoma undergoing retroperitoneal adrenalectomy. The primary outcome was postoperative hypotension requiring vasopressor support.

Design: A single-center retrospective observational study.

[Treatment of postoperative complications after surgery for esophageal cancer and cancer of the cardioesophageal junction].

Out of 108 patients with gastric and cardiac cancer and surgical complications, 49 were treated in the routine manner and 59 operatively. The immediate results were equal in either cases: 17 (34.7 +/- 6.

Surgery of localized cardioesophageal cancer.

In cardioesophageal cancer the 5-year survival was 52.5% for operations on patients without regional metastasis or involvement of the serous gastric membrane. When regional metastases were present, the 5-year-survival was 23.

Non-standard combination of radiation and surgery for esophageal cancer.

Three schemes of nonstandard combination of irradiation and surgery for esophageal cancer are presented: individual approach (IA), dynamic planning (DP), and sequential scheme (SS). In IA preoperative fractionation is adjusted to the tumor size. In DP esophageal resection is performed only in nonresponders to small-fraction 40-45 Gy radiation.

[Surgical and combined treatment of esophageal cancer].

The authors analyse 37-year experience in the treatment of patients with esophageal carcinoma by various methods at the All-Union Cancer Research Center. The immediate and long-term results of radiotherapy and surgical and combined treatment of 1,850 patients are shown. Bearing in mind the considerable extension of the neoplastic process by the time of the operation, the authors substantiate the expediency of one-stage operations with the formation of intrapleural esophagogastric anastomoses.

[Garlock's operation in cancer of the esophagus].

Experience in 88 Garlock-type operations carried out in carcinoma of the esophagus allows a certain opinion to be formed on the advantages and shortcomings of this surgical intervention. In esophageal carcinoma with its proximal boundary within the range of the retropericardial segment of the esophagus, a left abdominothoracic approach (Garlock's operation) is adequate in resection of the esophagus in conformity with the oncological principles and allows the formation of the esophagogastric anastomosis at the level of the arch of the aorta without particular technical difficulties. Reduction of the time needed for the operation, determination of the resectability of the esophageal tumor before mobilization of the stomach are obvious advantages of the abdominothoracic approach.

[The combination of chronic lympholeukemia with other malignant neoplasms].

Altogether 23 patients examined for secondary tumors at the All-Union Cancer Research Center of the USSR AMS underwent a clinical analysis. The overwhelming majority of the patients (17) were subjected to surgical intervention. Of these, none of the patients developed any postoperative complications or showed progress of chronic lympholeukemia (CLL).

[Computerized tomography in the surgery of esophageal cancer].

Preoperative X-ray computerized tomography (CT) was performed in 60 patients with carcinoma of the esophagus at the All-Union Oncology Research Centre, USSR AMS in 1986-1989. The method is evaluated on the basis of comparison with the operative findings in determining the depth of invasion of the esophageal wall and adjoining structures by the tumor, metastatic involvement of the lymph nodes below the diaphragm, and metastases in the liver. Informativeness of X-ray CT proved to be highest in patients in whom the tumor had not spread beyond the esophageal wall.
