Clinical utility of videofluorography with concomitant Tensilon administration in the diagnosis of bulbar myasthenia gravis.

Myasthenia gravis (MG) classically presents with ocular, bulbar, and predominantly proximal muscle weakness. Isolated bulbar symptoms occur in less than 25% of cases and can mimic stroke (1-3). If left untreated, MG can lead to significant morbidity and mortality, including myasthenic crisis and recurrent aspiration pneumonia. We describe a case of a 68-year-old man who presented with isolated bulbar symptoms. We used a novel approach to diagnosis which included a videofluorographic swallow study with concomitant Tensilon (edrophonium) injection.

Transgastric laparoscopic resection of a giant esophageal lipoma.

We present an unusual case of a giant, pedunculated esophageal lipoma originating in the mid-esophagus ball-valving through the gastroesophageal junction resulting in intermittent obstruction and hemorrhage. Endoscopic ultrasonography revealed a 1 cm in diameter vessel in the stalk of the polyp, and endoscopic resection was not performed. Transgastric laparoscopic resection with endoscopic guidance was successfully performed using 2 balloon-tipped laparoscopic trocars inserted laparoscopically into the gastric lumen through separate gastrotomies. Intraoperative esophagoscopy confirmed proper port placement and the exact location of the mass. Under direct visualization, a Snowden-Pencer grasper was used to pull the polyp down into the stomach and an Endo-GIA blue articulating stapler was used to transect its stalk. The polyp was retrieved via an endopouch placed through the intragastric laparoscopic port. We conclude that transgastric laparoscopy should be considered for the resection of a variety of pedunculated esophageal lesions when the use of standard endoscopic techniques is not possible.

Colonic ischemia associated with naratriptan use.

A 54-year-old woman with acute onset of hematochezia and lower abdominal pain proved to have ischemic colitis associated with the use of naratriptan. The diagnosis was established by colonoscopy with biopsy. There were no other obvious risk factors for intestinal ischemia. The condition resolved within 4 days. Because the use of triptans for the treatment of migraine is increasing, health care providers should be aware of their potential for inducing ischemic colitis.
