Initial Experience Using 3-Dimensional Printed Models for Head and Neck Reconstruction in Haiti.

This report describes the first use of a novel workflow for in-house computer-aided design (CAD) for application in a resource-limited surgical outreach setting. Preoperative computed tomography imaging obtained locally in Haiti was used to produce rapid-prototyped 3-dimensional (3D) mandibular models for 2 patients with large ameloblastomas. Models were used for patient consent, surgical education, and surgical planning. Computer-aided design and 3D models have the potential to significantly aid the process of complex surgery in the outreach setting by aiding in surgical consent and education, in addition to expected surgical applications of improved anatomic reconstruction

Portal Vein Gas, a Changing Clinical Entity. Report of 7 Patients and Review of the Literature.

OBJECTIVE: To assess the clinical significance of portal vein gas (PVG) demonstrated by computed tomography (CT). DESIGN: Review of medical records. SETTING: Three network-affiliated hospitals providing both primary community-based and tertiary services. METHODS: Review of diagnosis, clinical circumstances, and significance of PVG in 7 patients detected by CT during a 3-year period in 3 affiliated hospitals. RESULTS: Four of 7 patients underwent laparotomy; 1 patient refused surgery. Two patients were treated with intravenous antibiotics only and had uneventful clinical courses. Of the 3 patients who died, 1 refused and 2 underwent laparotomy. CONCLUSIONS: This series indicates that more sensitive imaging and more widespread use of endoscopic retrograde cholangiopancreatography, colonoscopy, and liver transplantation have changed the clinical presentation of PVG; PVG may be found in various clinical settings that do not mandate laparotomy; and the significance of PVG must be derived from the clinical context of the individual patient
