AIM To investigate the functional effects of abnormal esophagogastric(EGJ) measurements in asymptomatic healthy volunteers over eighty years of age. METHODS Data from 30 young controls(11 M, mean age 37 ± 11 years) and 15 aged subjects(9 M, 85 ± 4 years) were compared for novel metrics of EGJ-function: EGJcontractile integral(EGJ-CI), "total" EGJ-CI and bolus flow time(BFT). Data were acquired using a 3.2 mm, 25 pressure(1 cm spacing) and 12 impedance segment(2 cm) solid-state catheter(Unisensor and MMS SolarGI system) across the EGJ. Five swallows each of 5 m L liquid(L) and viscous(V) bolus were analyzed. Mean values were compared using Student's t test for normally distributed data or Mann Whitney U-test when non-normally distributed. A P value < 0.05 was considered *** EGJ-CI at rest was similar for older subjects compared to controls. "Total" EGJ-CI, measured during liquid swallowing, was increased in older individuals when compared to young controls(O 39 ± 7 mm *** vs C 18 ± 3 mm ***; P = 0.006). For both liquid and viscous bolus consistencies, IRP4 was increased(L: 11.9 ± 2.3 mm Hg vs 5.9 ± 1.0 mm Hg, P = 0.019 and V: 14.3 ± 2.4 mm Hg vs 7.3 ± 0.8 mm Hg; P = 0.02) and BFT was reduced(L: 1.7 ± 0.3 s vs 3.8 ± 0.2 s and V: 1.9 ± 0.3 s vs 3.8 ± 0.2 s; P < 0.001 for both) in older subjects, when compared to young. A matrix of bolus flow and presence above the EGJ indicated reductions in bolus flow at the EGJ occurred due to both impaired bolus transport through the esophageal body(i.e., the bolus never reached the EGJ) and increased flow resistance at the EGJ(i.e., the bolus retained just above the EGJ).CONCLUSION Bolus flow through the EGJ is reduced in asymptomatic older individuals. Both ineffective esophageal bolus transport and increased EGJ resistance contribute to impaired bolus flow.

Dysphagia lusoria: A late onset presentation

Dysphagia lusoria is a term used to describe dysphagia secondary to vascular compression of the oesophagus. The various embryologic anomalies of the arterial brachial arch system often remain unrecognised and asymptomatic, but in 30%-40% of cases can result in tracheo-oesophageal symptoms, which in the majority of cases manifest as dysphagia. Diagnosis of dysphagia lusoria is via barium swallow and chest Computed tomography scan. Manometric abnormalities are variable, but age-related manometric changes may contribute to clinically relevant dysphagia lusoria in patients who present later in life. Our report describes a case of lateonset dysphagia secondary to a right aortic arch with an aberrant left subclavian artery, which represents a rare variant of dysphagia lusoria. The patient had proven additional oesophageal dysmotility with solid bolus only and a clinical response to dietary modification.
