    Notes: Abstract The pathogenetic mechanisms causing esophageal dysmotility is not well understood. We examined 13 patients with solid bolus dysphagia in a radiologic barium study including, the swallowing of a 14-mm tablet. In all 13 patients the tablet was caught in the proximal or midesophagus. In 8 patients, the entrapment was associated with symptoms (Group 1) whereas in 5 patients (Group 2), no symptoms were reported. All 13 patients together with a control group of 56 healthy, nondysphagic subjects were tested for autonomic nerve function. Autonomic nerve function tests included registration of electrocardiographic R-R interval variation during deep breathing test (E/I ratio), a test of parasympathetic, vagal, nerve function. The results showed that the E/I ratio was significantly lower in patients with symptoms of bolus-specific esophageal dysmotility (-2,19 [1.76]) (median [interquartile range]) compared with patients without symptoms (0.05 [2, 87], p=0.0192) and controls (-0.25 [1.26], p=0.0009). In conclusion, symptomatic bolus-specific esophageal dysmotility is associated with vagal nerve dysfunction.

    Notes: Abstract Neurologic deficiencies, with special reference to pharyngeal function, were studied prospectively in 12 patients before and after they underwent carotid endarterectomy. Pharyngeal function was monitored with cineradiography. Five patients developed pharyngeal dysfunction: defective closure of the laryngeal vestibule, epiglottic dysmotility, and pharyngeal constrictor paresis 1 week postoperatively. In 2 patients this dysfunction remained, while in 3 it had resolved 4 weeks after the operation. Pharyngeal dysfunction was more common in patients with preoperative minor stroke and a temporary perioperative carotid shunt and in patients with a long operation time. The registered transient pharyngeal dysfunction may be due to manipulation of the cervical structures including the vagus nerve and the pharynx or due to cerebrovascular damage during the operation. Our findings support careful monitoring of postoperative oral feeding in patients at risk.
