Quality of life after oesophagectomy in patients with carcinoma of oesophagus: A prospective study.

Background: The present study was done to see if quality of life improves following oesophagectomy for carcinoma of oesophagus. Materials and Methods: This was a prospective study done from June 2007 to July 2009. All patients undergoing oesophagectomy and cervical anastomoses for squamous cell carcinoma and adenocarcinoma of oesophagus were included in the study. Quality of life assessment was done using EORTC QLQ C-30 and its oesophagus specific module (OES-18) before surgery and at 3, 6, 9 and 12 months. Results: There were 55 patients who underwent oesophagectomy for carcinoma of oesophagus. On the EORTC functional scale it was noted that patients undergoing transhiatal oesophagectomy showed significant improvement of emotional function only. Patients undergoing transthoracic oesophagectomy showed a decrease in functional scores in the first three months which improved later but this change was not significant. On the EORTC symptom scale, patients undergoing transhiatal oesophagectomy showed significant improvement of constipation but not in other symptoms. Patients undergoing transthoracic oesophagectomy showed an increase in symptoms for the first three months followed by a decrease which was significant with respect to scores for constipation and pain. On the EORTC oesophagus specific symptom scores, patients in both groups showed significant improvement of dysphagia and eating. Conclusion: Patients with carcinoma of oesophagus undergoing transhiatal oesophagectomy may not show significant improvement in quality of life. However there will be significant improvement in dysphagia and eating. Patients undergoing transthoracic oesophagectomy may show an initial decrease in the quality of life.

Bacterial isolates from mechanically ventilated patients with nosocomial pneumonia within intensive care unit of a tertiary care center.

Nosocomial pneumonia is a common complication in mechanically ventilated patients. A study was carried out to determine the incidence, common bacterial etiologic agents and their antimicrobial susceptibility, and outcome of such pneumonia in an Intensive Care Unit (ICU) of a tertiary care center. In Surgical ICU (SICU) 176 patients required mechanical ventilation for more than 72 hours. A total of 39 (22.1%) of these patients developed nosocomial bacterial pneumonia as determined by microbiological assays. Endotracheal aspirate cultures detected a single bacterial isolate in 22 (56.4%) patients while two and three organisms were isolated from 10 (25.6%) and 7 (17.9%) patients respectively. Fifty three (84.1%) of a total of 63 isolates were Gram negative bacilli. The most frequently encountered pathogens were Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter species among the Gram negative bacilli and Staphylococcus aureus among the Gram positives. Resistance of bacterial isolates varied from 24 to 90% against commonly used antibiotics. Amikacin had the best profile, with 14% to 55% resistance against various isolates. Twenty three (59%) of 39 patients with pneumonia expired in the ICU. P. aeruginosa (25.6%) and K. pneunmoniae (17.9%) were the predominant isolates in these patients. Nosocomial pneumonia with high mortality is a frequent occurrence in mechanically ventilated patients in our ICU setting. Gram negative organisms with high levels of antimicrobial resistance are the most common isolates. Regular surveillance and monitoring of changes in antibiotic susceptibility of bacterial pathogens and appropriate therapeutic measures are likely to reduce the mortality in these patients.
