The incidence of biliary tract pathologies increases as the population ages leading to an increase in the demand of therapeutic use of endoscopic retrograde cholangiopancreatography (ERCP). This study was carried out to assess the effectiveness of therapeutic ERCP in elderly patients. It was a prospective observational study. Patients aged 65 years or more referred for therapeutic ERCP from July 2007 to June 2008 were reviewed by a preformed data sheet which included all the relevant details of the procedure. It was collected at the time of ERCP & before discharge. Of 67 patients audited, successful therapeutic ERCP was performed in 91.04% cases. Our study showed that ERCP was effective in the elderly patients.Bangladesh Med J. 2016 Jan; 45 (1): 44-46

Abstract Background Early and accurate diagnosis of pancreatic cancer is important. Our aim was to identify potential volatile organic compounds (VOCs) in the bile that can help distinguish pancreatic cancer from chronic pancreatitis. Methods In this prospective observational study, bile was aspirated from patients undergoing endoscopic retrograde cholangiopancreatography for chronic pancreatitis and pancreatic cancer, and the gaseous headspace was analyzed using mass spectrometry. Results The study included a discovery cohort of 57 patients (46 pancreatic cancer, 11 chronic pancreatitis) and a validation cohort of 31 patients (19 and 12, respectively). Using logistic regression analysis, the model [0.158 × age + 9.747 × log (ammonia) – 3.994 × log (acetonitrile) + 5.044 × log (trimethylamine) – 30.23] successfully identified patients with pancreatic cancer with a sensitivity of 93.5 % and specificity of 100 % (likelihood ratio 40.9, area under the curve 0.98, 95 % confidence interval 0.95 – 1.00). The diagnostic accuracy of this model was confirmed in the second independent validation cohort. Conclusion The measurement of VOCs in bile helped to accurately distinguish pancreatic cancer from chronic pancreatitis.

Aim: This study was conducted to examine perioperative cerebral oximetry changes in elderly patients undergoing hip fracture repair and evaluate the correlation between regional oxygen saturation (rSO2) values, postoperative cognitive dysfunction (POCD) and hospital stay. Materials and Methods: This prospective observational study included 69 patients. Data recorded included demographic information, rSO2 values from baseline until the second postoperative hour and Mini Mental State Examination (MMSE) scores preoperatively and on postoperative day 7. MMSE score ≤23 was considered evidence of cognitive dysfunction. Postoperative confusion or agitation, medications administered for postoperative agitation, and hospital length of stay were also recorded. Data were analyzed with Student’s t-test, Pearson’s correlation or multiple regression analysis as appropriate. Results: Patient age was 74±13 years. Baseline left sided rSO2 values were 60±10 and increased significantly after intubation. Baseline rSO2 L<50 and <45 was observed in 11.6% and 10.1% of patients respectively. Perioperative cerebral desaturation occurred in 40% of patients. MMSE score was 26.23 ± 2.77 before surgery and 25.94 ± 2.52 on postoperative day 7 (p=0.326). MMSE scores ≤ 23 were observed preoperatively in 6 and postoperatively in 9 patients. Patients with cognitive dysfunction had lower preoperative hematocrit, hemoglobin, SpO2 and rSO2 values at all times, compared to patients who did not. There was no correlation between rSO2 or POCD and hospital stay. Patients with baseline rSO2 <5 required more medications for postoperative agitation. Conclusion: Cognitive dysfunction occurs preoperatively and postoperatively in elderly patients with hip fractures, and is associated with low cerebral rSO2 values.
