Prediction of Postoperative Complications: Ventilatory Efficiency and Rest End-tidal Carbon Dioxide.

Background: Cardiopulmonary exercise testing parameters including ventilatory efficiency (V/VCO slope) are used for risk assessment of lung resection candidates. However, many patients are unable or unwilling to undergo exercise. V/VCO slope is closely related to the partial pressure of end-tidal carbon dioxide (PCO).

Acute hiatal hernias.

Introduction: In surgical practice, hiatal hernias are often related to gastro esophageal reflux disease treatment in which continuous proton pump inhibitor administration is very successful. In large hiatal hernias, life threatening complications may occur. However, planned surgical repair of hiatal hernias is associated with very good functional outcomes with a low risk of postoperative complications.

Results of minimally invasive esophagectomy for esophageal cancer performed after ischemic gastric conditioning.

Introduction: Esophageal tumor resections are extensive procedures with high postoperative complication rates including anastomotic leak. An anastomotic leak occurs when microcirculation in the proximal gastric wall used for esophageal replacement is impaired. Preoperative occlusion of certain gastric vessels (ischemic gastric conditioning) may lead to changes in vascularization and can potentially reduce the occurrence and severity of anastomotic leak after esophageal resection.

[Complications in patients undergoing pulmonary oncological surgery].

Aim: A survey evaluating incidence and risk factors of complications in persons underwent complete open lung resection because of primary or secondary lung malignancy.

Material And Methods: Retrospective study of 189 open surgery procedures in 128 males and 61 females, mean age males 61 years (range 21-78), females 64 years (range 33-80) during a five-years period (2003-2007). Data processing and analysis were performed with the statistical software system Statistica and compared by parametres odds ratio a chi2 test.

[Benign lymphoepithelial cyst of the pancreas: a case report].

Lymphoepithelial cyst of the pancreas represents an extremely rare and benign entity of undetermined pathogenesis. This lesion must be taken into consideration in the differential diagnosis of pancreatic cystic lesions. A case of resected lymphoepithelial cyst of pancreas in 59-year-old man with an attack of acute pancreatitis in anamnesis is reported.
