Patients with gastroesophageal reflux disease and respiratory manifestations do not present lung function disorders during cardiopulmonary exercise test.

Gastroesophageal reflux disease (GERD) has been associated with a variety of pulmonary manifestations, but it is unclear if gastroesophageal reflux causes any abnormality in pulmonary function. Cardiopulmonary exercise test (CPET) is a specialized method that is used to evaluate respiratory function during exercise. The aim of this study was to reveal any abnormality of pulmonary function in patients with GERD and respiratory symptoms. We evaluated 34 patients with GERD (24 men and 10 women, aged 21-63) and extraesophageal respiratory symptoms (wheezing and/or cough) before therapy and after a 12-week treatment with double dose of omeprazole. No patient presented abnormal spirometry. CPET was performed in all the patients at baseline and after completion of the 12-week treatment. CPET parameters including VO(2) rest, VO(2) max, VCO(2) rest, VCO(2) max, O(2)-puls rest, O(2)-puls max, HR (heart rate) rest, HRmax, PETCO(2) rest, PETCO(2) max, and VE/VCO(2) slope were recorded pretreatment and posttreatment. Twenty-four patients (70.6%) had esophagitis (grade A-D), 16 patients had hiatal hernia (47.1%), and 13 patients (38.2%) tested positive for Helicobacter pylori. All of the patients completed the CPET. No one presented shortness of breath or respiratory symptoms. CPET parameters were within normal limits in all of the patients. Twenty-eight patients were reevaluated. No improvement in any CPET parameter posttreatment was observed despite remission of esophageal and extraesophageal respiratory symptoms in all patients. No statistically significant difference was observed pretreatment and posttreatment between the patients older and younger than 40 years, smokers and nonsmokers, Hp(+) and Hp(-) patients, and those with and without hiatal hernia and esophagitis. The patients with GERD and respiratory manifestations and normal spirometry present no pulmonary dysfunction during CPET. No alterations in CPET values posttreatment or differences in CPET values according to age, smoking, Hp status, presence of esophagitis, or hiatal hernia were observed.

Endoscopic retrogade cholangiopancreatography is safe and effective method for diagnosis and treatment of biliary and pancreatic disorders in octogenarians.

BACKGROUND AND AIM: Diagnosis and treatment of pancreatic and biliary diseases represents a special problem in old patients who often suffer from one or more concomitant diseases. The aim of this study was to evaluate the safety and efficacy of ERCP in very old patients (octogenarians). PATIENTS AND METHODS: Patients 80 years or older who underwent ERCP from October 2001 to December 2005 were studied retrospectively. RESULTS: A total of 209 patients (121 women, 88 men), with a mean age 86 +/- 4.4 years old (80-102) underwent 251 ERCPs. All but three patients tolerated the procedure well. Three procedures were not completed due to patients' discomfort (1.4%). Two of these patients underwent percutaneous transhepatic cholangiography and the other one was treated conservatively. A cholangiogram was obtained in 193 cases (92.3%), although in 7 patients an additional attempt was required. The main endoscopic findings were common bile duct stones in 51.8% (100/193) and cancer in 28% (54/193) of patients. Based on the diagnostic findings, a therapeutic intervention was indicated in 189 patients (90.4%) and was achieved in 181 of them (95.8%). Complications were observed in 9.6% of ERCPs (24/251). Post - ERCP mild pancreatitis was the more frequent complication in 11 procedures (4.4%). No severe pancreatitis was observed. Six procedures were complicated by cholangitis (2.4%) and two by cholecystitis (0.8%). Early surgical intervention was required in 2 cases because of oesophageal perforation and retroperitoneal perforation respectively. Two patients died (0.8%); one patient with pancreatic cancer died due to septic shock after inadequate biliary drainage and the other one died after operation for retroperitoneal perforation. CONCLUSIONS: In conclusion, ERCP is safe and effective method for diagnosis and treatment of biliary and pancreatic disorders in octogenarians despite the high comorbidity in this group of patients.
