A rare case of ganglioneuromatous polyposis of the colon found in association with mucinous adenocarcinoma and primary hyperparathyroidism caused by a parathyroid adenoma in a 77-year-old woman is described. We discuss the clinical implications of this finding and review the literature.
OBJECTIVE: To analyze the use of self-expanding metal coated esophageal stents a palliative therapy of malignant dysphagia. METHOD: We performed a one year prospective study placing 12 stents in 10 patients with malignant dysphagia. RESULTS: The insertion mean time was lower than 25 min, and most of our patients (70%) reported a good tolerance. Dysphagia score improved immediately and it lasted until death with no occlusions. Complications appeared early, 17% at the time of placement, with one patient having a life-threatening complication. The probability for these patients not to develop any complications after the three first weeks will be about 60%. CONCLUSIONS: Self-expanding metal coated esophageal stents provide a fast and lasting relief in malignant dysphagia, with a good tolerance.
A case of localized phlegmonous gastritis is reported. Features of this condition and the diagnostic and therapeutic usefulness of endoscopy are briefly considered.
Squamous papilloma of the esophagus is a benign tumor. The diagnosis is usually made accidentally when an upper gastrointestinal endoscopy is performed due to upper abdominal or esophageal symptoms. After having reviewed 14,900 upper gastrointestinal endoscopies during the past 8 yr, we report six additional cases of esophageal squamous papilloma. The lesion seems to be relatively quiescent without apparent malignant changes, at least on a short-term basis. The etiology is unknown; however, we conclude that gastroesophageal reflux may predispose to the lesion and that endoscopic follow-up on these patients may be unnecessary due to the benign nature of the lesion.
