## Abstract The collision technique was used to determine the origin of distal fasciculations in 25 motor units from 9 patients with amyotrophic lateral sclerosis and 6 with other diseases involving motoneurons. Fasciculations originated in the nerve proximal to the knee or elbow in 15 and distally

✦ Synopsis
A 35-year-old male patient presented with symptoms of a cramp-fasciculation syndrome, but also reported difficulties swallowing. Esophageal manometry showed spontaneous nonperistaltic contractions, pathologically increased amplitudes and duration of the contractile complexes, and an asynchronous propagation. Electromyographic evidence of fasciculations in the sternocleidomastoid and pectoralis muscles was found. Apparently all types of peripheral motor fibers can be involved in this heterogeneous syndrome, including cranial motor nerves, the vagal nerve, and enteric motor fibers of the gastrointestinal tract.

## Background and Objectives: In carcinoma of the thoracic esophagus, most surgeons consider that esophagectomy is contraindicated in patients with clinical evidence of major extraesophageal involvement in the lower neck or peritracheal regions. However, metastases to these regions are commonly fo
