Anastomotic leaks are a serious complication associated with Ivor Lewis esophagectomies. Endoluminal negative pressure vacuum devices create a possible treatment alternative to conventional surgical intervention. Ten pigs had an intrathoracic esophageal anastomosis with a 1-cm defect. The experimental group had the device placed intraoperatively across the defect, whereas the control group did not. Once treatment was completed, a contrast fluoroscopic study and necropsy was performed. All control pigs had contrast extravasation on fluoroscopy and contamination on necropsy. The experimental group had no radiologic leak and no contamination on necropsy. The P value for leak is 0.03. This study demonstrated that endoluminal negative pressure vacuum therapy is tolerated in the swine model and is successful in facilitating the healing of anastomotic leaks. Endoluminal negative pressure vacuum therapy has potential clinical benefits, including decreased morbidity and length of hospital stay.

Objective To characterize epidemiologic and clinical features of red primary amelanotic melanomas, an atypical presentation of melanoma that is underemphasized in patient and physician education. Patients and methods Review of a prospectively collected melanoma database identified 46 patients with red amelanotic melanomas, whose clinical features were compared with 329 patients with pigmented melanomas from the same database and same timeframe from January 1964 to September 2005. Results Red amelanotic melanomas represented 3.9% of all melanomas recorded in our database and accounted for nearly 70% of amelanotic melanomas. Melanoma was included in the clinical differential diagnosis in 32% of red amelanotic melanomas vs. 94% of pigmented melanomas (P

Introduction Metastatic melanoma has few FDA approved treatments, and aggressive surgical resection has to be considered for management of bulky axillary metastases. We hypothesized that axillary resection in this setting is well tolerated and improves symptoms in the majority of patients.
