Few studies have examined outcomes of laparoscopic and open sigmoid colectomy performed at US academic centers. Using ICD-9
diagnosis and procedural codes, data was obtained from the University HealthSystem Consortium (UHC) Clinical Database of 10,603
patients who underwent laparoscopic or open sigmoid colectomy for benign and malignant disease between 2003–2006. A total
of 1,092 patients (10.3%) underwent laparoscopic sigmoid colectomy. Laparoscopic sigmoid colectomy was associated with a significantly
shorter length of stay (5.4 vs 7.4 days), lower overall complication rate (19.7 vs 26.0%), lower 30-day readmission rate (3.4
vs 4.6), and a lower hospital cost ($13,814 vs $15,626). When a subset analysis of malignant and benign groups was performed,
a significantly shorter length of stay in both the malignant laparoscopic group (6.4 ± 6.4 vs 7.8 ± 6.6 days) and in the benign
laparoscopic groups (5.1 ± 3.5 vs 7.2 ± 7.6) exists. A lower wound complication rate (2.1 vs 5.5%, malignant and 4.0 vs 6.1,
benign) is also evident. Laparoscopic sigmoid colectomy was associated with a shorter length of stay, less complications,
and a lower 30-day readmission rate. The shorter length of stay and wound infection rate maintain significance when comparing
laparoscopic vs open sigmoid resections for malignant and benign disease.

Summary This study deals with 49 fractures of the dens treated at the Orthopedic Department of Athens University during the past 17 years. These fractures represent 14.2% of all cervical fractures treated during the same period at our department. Forty-one cases have been reviewed and analyzed, the average follow-up time being 10 years (1–16). Pseudarthrosis was found to be present in seven cases (17%), and its relationship to different factors was examined. The type of fracture and particularly the direction of the fracture line were found to be major factors leading to pseudarthrosis. Many other factors, such as displacement, traction, the stability obtained, the presence of associated injuries, and the time elapsed till treatment was started, as well as the age of the patients, seem to play — alone or in combination — important roles in the development of pseudarthrosis. These factors have been classified according to their importance and graded. With a total of 10 points or more a dens fracture is characterized as a fracture at risk of pseudarthrosis, i.e., a fracture with a higher possibility of developing a pseudarthrosis. This knowledge may contribute to proper and earlier management of such an injury. 相似文献

Closed tendon injuries of the hand and wrist are very common in the athletic population. Most of these injuries, especially those involving the extensor tendons, can be treated successfully with nonoperative management if seen acutely. Acute closed flexor tendon injuries, however, usually require operative intervention for the best result. Although evaluation and diagnosis of flexor tendon injuries are relatively straightforward, diagnosis is still commonly delayed secondary to both delayed presentation and missed diagnoses. If diagnosis is delayed, operative intervention becomes less optimal and the patient may have a permanent disability regardless of treatment. Generally, athletes are able to return to their pre-injury level of participation regardless of treatment. This is a product of both the finger involved--usually ring or little--and the extent of the disability. In many instances, the athlete may even continue participation during treatment with protective splinting. 相似文献

Tracheobronchopathia osteochondroplastica (TO) is a rare benign disease characterized by the presence of osseous and cartilaginous submucosal nodules projecting into the tracheobronchial tree. Most cases are asymptomatic and discovered incidentally at post‐mortem. We identified a case of TO on thoracic spiral CT and confirmed the diagnosis on bronchoscopy. This article reviews the imaging characteristics of TO, and shows the 3‐D virtual bronchoscopic and multiplanar reconstruction appearances of TO. 相似文献

The present study compared the accuracy of ventilation perfusion scintigraphy (VQS) and CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism. This was a prospective observational study of 112 patients with suspected pulmonary embolism (PE) who could be studied with both investigations within 24 h. Results were compared to final diagnosis at completion of 6-month follow up, using receiver operating characteristic (ROC) analysis. Pulmonary embolism was diagnosed in 27 referred patients (24%). The sensitivity and specificity of VQS and CTPA were similar to that reported from the literature. A normal VQ scan had the highest negative predictive value (100%), while a high-probability VQ scan had the highest positive predictive value (92%). There was no overall difference (area under the ROC curve (AUC)) between VQS (AUC (95% CI) = 0.82 (0.75,0.89)) and CTPA (AUC = 0.88 (0.81,0.94)) for the diagnosis of PE. Among patients with abnormal chest X-rays, CTPA (AUC 0.90 (0.83,0.97)) appeared somewhat better than VQS (AUC 0.78 (0.68,0.88)) but this difference did not reach statistical significance. In this instance, CTPA is at least as accurate as VQS and may provide an opportunity to make alternative diagnoses. 相似文献
