Operative Death (operative + death)
Selected AbstractsSurgery in thoracic esophageal perforation: primary repair is feasibleDISEASES OF THE ESOPHAGUS, Issue 3 2002S. W. Sung SUMMARY. Prompt diagnosis and effective treatment are important for thoracic esophageal perforations. The decision for proper management is difficult especially when diagnosed late. However, there is an increasing consensus that primary repair provides good results for repair of thoracic esophageal perforations, which are not diagnosed on time. Primary repair for thoracic esophageal perforations was applied in 20 out of 25 consecutive patients. The time interval between perforation and repair was less than 24 h in six patients (group I), and more than 24 h in 14 patients (group II). The remaining five patients underwent esophagectomy with simultaneous or staged reconstruction because of incorrectable underlying esophageal pathology. Group I had much more iatrogenic causes (P < 0.05). Preoperative sepsis occurred only in group II (P=0.05) and was highly associated with Boerhaave syndrome (P=0.001). Regional viable tissue was used to reinforce the sites of primary repair (n=15, 75%). All of the postoperative morbidity (n=9, 45%) including esophageal leaks (n=6, 30%) and operative death (n=1, 5%) occurred in group II. In patients with postoperative leaks, five eventually healed, but one became a fistula that required reoperation. Primary healing with preservation of the native esophagus was achieved in all 19 patients except one operative death. In addition, the increased incidence of leak and morbidity did not lead to an increase in mortality. In the esophagectomy group, there was no mortality, but one minor suture leak. Regardless of the time interval between the injury and the operation, primary repair is recommended for non-malignant, thoracic, esophageal perforations, but not for anastomotic leaks. Reinforcement that may change the nature of a possible leak is also useful. For incorrectable underlying esophageal pathology, esophagectomy with simultaneous or staged reconstruction is indicated.

The aim of this study is to present the principles of "radical" management that should be targeted to excision of the kidney together with the cavoatrial tumor-thrombus. Material: From 2003 through 2008, we treated six patients with renal-cell carcinoma involving the IVC and/or the right cardiac chambers. The main symptoms leading to the diagnosis were hematuria, dyspnea, or lower limb edema. The extension of the tumor was type IV in three cases, type III in two, and type II in one case. Method: Extracorporeal circulation combined with a short period of hypothermic circulatory arrest was the method used. Radical nephrectomy combined with cavotomy and atriotomy was performed to an "en-block" extirpation of the tumor-thrombus and allowed oncologic surgical clearance of the disease. Results: There was no operative death. The mean postoperative course duration was 11 days, apart from one obese patient who presented postoperative pancreatitis and died on the 44th postoperative day due to respiratory failure. During the cumulative postoperative follow-up of 171 months the patients remain free of recurrence. Conclusions: The use of extracorporeal circulation and deep hypothermic circulatory arrest provides a good method for radical excision of renal carcinomas involving the IVC with satisfactory morbidity and long-term survival results. Cooperation of urologists and cardiac surgeons is necessary for this type of operation. [source] Minimized Mortality and Neurological Complications in Surgery for Chronic Arch Aneurysm:JOURNAL OF CARDIAC SURGERY, Issue 4 2004Axillary Artery Cannulation, Replacement of the Ascending, Selective Cerebral Perfusion, Total Arch Aorta For preventing this complication, axillary artery cannulation, selective cerebral perfusion, and replacement of the ascending and arch aorta were applied to thoracic aortic aneurysm involving aortic arch. Method: From May 1999 to July 2002, consecutive 39 patients with true aneurysm (29 patients) or chronic aortic dissection (10 patients) involving aortic arch underwent replacement of the ascending and arch aorta with an elephant trunk under hypothermic cardiopulmonary bypass through the axillary artery cannulation and selective cerebral perfusion. The brain was continuously perfused without any intermission through the axillary artery. Concomitant operation included coronary artery bypass grafting (CABG) in two patients, aortic valve replacement (AVR) in one, Bentall operation in two, mitral valve replacement (MVR) in one, and aortic valve sparing operation in one. Patient age at operation was 40,84 (72 + 9) years and 24 of them were older than 70 years of age. Results: There was one operative death (2.5%) due to bleeding from the left lung, and one hospital death due to respiratory failure. Postoperative permanent neurological dysfunction was found in one patient (2.5%). Two patients presented temporary neurological dysfunction (5%). Thirty-six of the 39 patients were discharged from hospital on foot. Conclusion: Continuous perfusion through the axillary artery with selective cerebral perfusion and replacement of the ascending and arch aorta may minimize cerebral complication leading to satisfactory results in patients with chronic aortic aneurysm involving aortic arch. [source] Predictors of operative death after oesophagectomy for carcinomaBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 8 2005H. Abunasra Background: Oesophagectomy for carcinoma provides a chance of cure but carries significant risk. This study defined risk factors for death after oesophageal resection for malignant disease. Methods: Between 1990 and 2003, 773 oesophagectomies for oesophageal cancer were performed. Continuous variables were categorized into quartiles for analysis. Predictors of operative mortality were identified by univariate and multiple logistic regression analysis. Results: The operative mortality rate was 4·8 per cent (37 of 773). In univariate analysis, advanced age, reduced forced expiratory volume in 1 s (FEV1), reduced forced vital capacity, presence of diabetes and tumour located in the upper third of the oesophagus were associated with a higher mortality rate. Multivariate analysis identified age (highest relative to lowest quartile, odds ratio (OR) 4·87 (95 per cent confidence interval (c.i.) 1·35 to 17·55); P = 0·009), tumour position (upper third relative to other locations, OR 4·23 (95 per cent c.i. 1·06 to 16·86); P = 0·041) and FEV1 (lowest relative to highest quartile, OR 4·72 (95 per cent c.i. 1·01 to 21·99); P = 0·018) as independent predictors of death. Conclusion: Advanced age, impaired preoperative respiratory function and a tumour high in the oesophagus are associated with a significantly increased risk of death after oesophagectomy for carcinoma.

[source] Aortic Arch Surgery With a Single Centrifugal Pump for Selective Cerebral Perfusion and Systemic CirculationARTIFICIAL ORGANS, Issue 1 2010Keiji Iwata Abstract In aortic arch surgery, two pumps are required for systemic perfusion and selective cerebral perfusion (SCP). A new technique with a single centrifugal pump for systemic perfusion and SCP was developed and its efficacy and safety evaluated. This technique was adopted for total arch replacement in 22 consecutive patients with true aneurysms (13) and aortic dissection (nine) from January 2005 to January 2008. Cerebral perfusion lines branched from the main perfusion line. During SCP, right radial arterial pressure was maintained at 50 mm Hg and left common carotid arterial pressure at 60 mm Hg, and the regional cerebral oxygen saturation (rSO2) values were maintained at approximately >80% of the baseline value. Two operative deaths (9%) occurred due to pneumonia and hemorrhage in the left lung, respectively. Stroke occurred in one patient (5%). This simple circuit system can thus be easily and safely applied for aortic arch surgery. [source] | ||||||||||
