Superior mesenteric artery aneurysm: 45 years later.

Superior mesenteric artery aneurysms (SMAAs) have been described for the past 100 years, with the first successful treatment being published in 1953 by Drs. M.E. DeBakey and D.A. Cooley. It is now 45 years after this first successful treatment, and we have a case study of SMAA that depicts the typical presentation and treatment of such an aneurysm. Our SMAA was repaired with proximal and distal ligation of the aneurysm, with intestinal viability determined by Doppler probe, fluorescein dye and repeated laparotomy in 24 hours. The patient tolerated the procedure well, and there were no postoperative sequelae. In general, SMAAs have a broad range of treatments, including vessel ligation with or without excision, revascularization with primary anastomosis, and obliterative aneurysmorrhaphy. In the future, these SMAAs and other visceral aneurysms can be treated with transluminally placed endovascular grafts with the combined efforts of the vascular surgeon and the interventional radiologist. Our article provides an overall examination of SMAAs with a review of the literature.

149 ambulatory laparoscopic cholecystectomies.

BACKGROUND: The purpose of this study was to compare ambulatory laparoscopic cholecystectomy (LC) with overnight LC and to determine its safety and the factors which will predict its success. METHODS: Ambulatory LC was defined as LC followed by less than a 12-h stay in the ambulatory surgery unit; overnight LC was defined as LC followed by a hospital admission of less than 24 h. A retrospective chart review was completed. RESULTS: One hundred forty-nine ambulatory LC, were performed in an 18-month period. Ninety-one were successful (61%); 58 patients required overnight admission for pain management, control of nausea, or their reluctance to be discharged. There were five complications and no mortalities. The duration of the surgical procedure was the only significant objective factor we could find in predicting success of ambulatory LC. CONCLUSIONS: We conclude that ambulatory LC is safe and effective in treating patients requiring cholecystectomy. The duration of the procedure and the patient's own motivation are key factors in predicting success of early discharge.

Disruption of the proximal anastomosis of axillobifemoral grafts: two case reports.

The use of axillobifemoral grafting in the treatment of infected aortic prostheses or in the treatment of patients at high risk for aortoiliac occlusive disease has become a widely accepted treatment modality. Few complications involving the proximal anastomosis have been reported. The present report describes two patients who suffered proximal anastomotic dehiscence several weeks after surgery when they fully extended and raised the affected arm.

Subcutaneous angiolymphoid hyperplasia (Kimura disease). Report of a case.

A subcutaneous mass removed from the cheek showed histologic features of subcutaneous angiolymphoid hyperplasia (Kimura disease) at its early stage. The condition shows a wide spectrum of pathologic changes. At its early stage, the main findings consist of active vascular proliferation with plump endothelial cells and varying degrees of lymphocytic, histiocytic, and eosinophilic infiltration. The lesion at its later stage features hyperplastic blood vessels with inconspicuous endothelial cells, well-formed lymphoid follicles, and varying degrees of lymphocytic and eosinophilic infilitration. Blood eosinophilia is frequently seen. Review of the literature and study of our own case strongly suggest that this disease is a distinct clinical and pathologic entity.
