    ABSTRACT: We demonstrate indications for external mechanical stapler diverticulectomy in the modern era of endoscopic treatment. We review treatment of a large diverticulum and discuss considerations that should be made in deciding on the type of surgical treatment. The index case was in a 75-year-old man who had undergone open cricopharyngeal myotomy with diverticulopexy 35 years earlier. He presented with 25 years of recurrent symptoms. A swallow study showed a 6.5 x 5.0-cm diverticulum. The diverticulum was deemed too large for standard endoscopic myotomy, so diverticulectomy was performed with a stapler. The patient was discharged on postoperative day 3 without complications. A swallow study on postoperative day 5 demonstrated no diverticulum or extravasation of barium. The patient resumed a normal diet with resolution of dysphagia. Two additional patients with large Zenker's diverticula that were managed similarly are also discussed. Although endoscopic laser cricopharyngeal myotomy and stapler diverticulostomy have become standard treatments for Zenker's diverticulum, this case of a large recurrent diverticulum illustrates a situation in which older techniques may be preferred. Use of the mechanical stapler allowed for a shorter surgery time than traditional suture techniques, and the potential for an earlier return to a normal diet.

    ABSTRACT: Intraoral exposure to dental restorations can cause contact allergy that may induce carcinogenesis. We investigated the relationship of intraoral metal contact allergy to epithelial carcinogenesis. The prevalence of positive patch test reactions to dental restoration metals in 65 prospectively enrolled patients with newly or previously diagnosed oral squamous cell carcinoma (SCC) was compared to that in 48 control patients. The relative risk of oral SCC was estimated by calculating odds ratios for exposure to dental metals resulting in allergy. Of the 65 patients with oral SCC, 34% were allergic to at least 1 adjacent metal. They were 1.57 times as likely as control patients to have metal contact allergy (odds ratio, 1.57; 95% confidence interval, 0.65 to 3.80) and more than 3 times as likely to react to mercury (odds ratio, 3.20; 95% confidence interval, 0.42 to 33.20). Patients with oral SCC who have metal dental restorations should undergo patch testing and possible removal of the restorations if their reactions are positive.
