Chondrosarcomas of the hand are rare and generally treated with surgical resection. Thirteen patients with Grade 1 chondrosarcoma of the small bones of the hand were followed up for a mean of 99.8 months (range, 26-293 months). In eight patients (Group 1) curettage and reconstruction with cancellous bone was done and in five patients (Group 2) a wide resection was done. No patient experienced relapse in Group 2. In Group 1 one patient had a local relapse 18 months after intralesional resection. Using the Musculoskeletal Tumor Society score for evaluation, the clinical results showed an average of 98% and 95% of the normal function in Groups 1 and 2, respectively. None of the patients had evidence of systemic spread of the disease. With a relapse rate of 12.5% and no distant metastases after curettage, intralesional resection is the preferred method of treatment in Grade 1 chondrosarcoma of the hand, allowing the patient to avoid amputation and major loss of function.  相似文献

OBJECTIVE: Interventional radiologists, cardiologists, and vascular surgeons are capable of performing endovascular procedures successfully in their respective environments. Suboptimal anatomy or intraoperative technical problems can be encountered, and endovascular management alone is not always suitable. The objectives of this study were to define the incidence of adjunctive surgical techniques, to discuss the rationale for endovascular reconstruction in a well-developed surgical environment, and to assess the effect of experience on the incidence of adjunctive repair. METHODS: All primary aortic and aortoiliac elective, urgent, and emergent endovascular procedures performed at the Peter Lougheed Center and entered into a prospective database from May 25, 1999 to June 01, 2005, were reviewed. All adjunctive surgical techniques to enable stent deployment, enhance attachment site, or solve intraoperative difficulties were captured. The study period was divided into two time periods based on learning curve data to assess the effect of experience on the rate of adjunctive repairs. RESULTS: Four hundred thirty-eight patients underwent elective (80%), urgent (15%), or emergent (5%) endovascular procedures during the study period. These consisted of 101 thoracic and 337 abdominal operations, including the use of 13 fenestrated stents. One hundred thirty-nine patients (31.7%) required 180 open surgical procedures. Complete data were available for the entire patient cohort. The mean follow-up was 793.2 days (SD, 519.1 days). Procedures were necessary for vascular access, arterial dissection/rupture, limb ischemia, and enhancement/elongation of the stent attachment site. The persistent endoleak rate was 5.3%, the late rupture rate was 0.7%, the conversion rate was 1.6%, the 30-day surgical mortality rate was 3.2%, all-cause mortality to date is 7.3%, and the reintervention rate was 4.6%. There was no statistically significant effect of the learning curve on the incidence of surgical adjunctive procedures in either the thoracic group (11/26 [42.3%] for phase 1 vs 17/75 [22.6%] for phase 2) or the abdominal group (14/50 [28.0%] for phase 1 vs 97/287 [33.8%] for phase 2). Overall, 31.5% of patients required adjunctive surgical repair. CONCLUSIONS: Successful endografting requires endovascular expertise in addition to a well-developed surgical environment to increase applicability and decrease patient risk. Despite advances in endovascular technology, hybrid techniques will continue to be required to achieve good overall success rates.  相似文献

BACKGROUND: Previous studies have suggested that patients transported by emergency medical services (EMS) following major trauma had a longer injury-to-treatment interval and a higher mortality rate than their non-EMS-transported counterparts. HYPOTHESIS: There is little actual benefit of thoracolumbar immobilization for patients with torso gunshot wounds (GSW). DESIGN: Retrospective analysis of prospectively gathered data from the Maryland Institute for Emergency Medical Service Systems State Trauma Registry from July 1, 1995, through June 30, 1998. SETTINGS: All designated trauma centers in Maryland. PATIENTS: All patients with torso GSW. MAIN OUTCOME MEASURES: (1) A patient was considered to have benefited from immobilization if he or she had less than complete neurologic deficits in the presence of an unstable vertebral column, as shown by the need for operative stabilization of the vertebral column; (2) mortality. RESULTS: There were 1000 patients with torso GSW. Among them, 141 patients (14.1%) had vertebral column and/or spinal cord injuries. Two patients (0.2%) (95% confidence interval, -0.077% to 0.48%) required operative vertebral column stabilization, while 6 others required other spinal operations for decompression and/or foreign body removal. The presence of vertebral column injury was actually associated with lower mortality (7.1% vs 14.8%, P<.02). CONCLUSIONS: This study suggests that thoracolumbar immobilization is almost never beneficial in patients with torso GSW, and that a higher mortality rate existed among those GSW patients without vertebral column injury vs those with such injuries. The role of formal thoracolumbar immobilization for patients with torso GSW should be reexamined.  相似文献

Trauma to epidural catheters on insertion or removal may result in shearing or breakage. Although there is no evidence of neurologic sequelae from a sheared catheter, many reports still advocate eventual surgical removal. The literature suggests the following options: (1) using slow continuous force at all times; (2) discontinuing application of force if the catheter begins to stretch and reapplying traction several hours later; (3) placing of the patient in the same position as insertion; (4) placing the patient in the lateral decubitus position if possible; (5) attempting to remove in extreme flexion if the previous interventions are not efficacious; (6) attempting extension if flexion fails; (7) attempting removal after injection of preservative-free normal saline through the catheter; (8) considering use of a convex surgical frame; (9) considering computed tomographic scan to identify the etiology of entrapment; (10) considering leaving a retained epidural catheter in place in adult patients; (11) providing patient education regarding "red flags" to watch out for; and (12) neurosurgical consultation for all cases in which the catheter fragment is in the spinal canal.  相似文献

INTRODUCTION

This paper assesses the outcomes of patients after surgery for a proximal femur fracture while on clopidogrel. It describes a single-centre retrospective observational study over a two-year period.

PATIENTS AND METHODS

A total of 31 surgical patients were included in this study. Of these, 28 were on clopidogrel and 3 on dipyridamole. Patients were split into subgroups based on when surgery took place and the type of hip fracture. The ‘early surgery’ (<48 hours from admission to theatre) group contained 16 patients (51.6%) and the ‘late surgery’ (>48 hours) group composed 15 patients (48.4%). Type of surgery performed and pre-and postoperative haemoglobin (Hb) levels were recorded. Furthermore, the number of units of blood transfused per patient as well as complications before and after surgery were noted.

RESULTS

A significantly larger mean Hb drop occurred in the early surgery group (3.2g/dl) compared with the late surgery group (2.3g/dl) (p=0.027). The mean length of inpatient stay was 21 days in the early and 23 days in the late group (p=0.456). A significantly larger Hb mean drop occurred in patients with extracapsular hip fractures (3.4g/dl; n=16) compared with patients with intracapsular fractures (2.3g/dl; n=15) (p=0.020). The extracapsular patients had longer stays in hospital: 24.5 days versus 19.8 days in the intracapsular group (p=0.521). There was no statistical difference in the 30-day mortality between the early surgery (3/16 deaths) and late surgery (2/15 deaths) groups (p=0.481).

CONCLUSIONS

Patients with extracapsular fractures, treated with early surgery, appear to be most at risk of complications after surgery.  相似文献

In many centers internationally, current standard of care is to excise all papillomas of the breast, despite recently reported low rates of upgrade to malignancy on final excision. The objective of this study was to determine the upgrade rate to malignancy in patients with papilloma without atypia. A retrospective review of a prospectively maintained database of all cases of benign intraductal papilloma in a tertiary referral symptomatic breast unit between July 2008 and July 2018 was performed. Patients with evidence of malignancy or atypia on core biopsy and those with a history of breast cancer or genetic mutations predisposing to breast cancer were excluded. One hundred and seventy‐three cases of benign papilloma diagnosed on core biopsy were identified. Following exclusions, the final cohort comprised of 138 patients. Mean age at presentation was 51. Mean follow‐up time was 9.6 months. The most common symptom was a lump (40%). Of the 124 patients who underwent excision, three had ductal carcinoma in situ and there were no cases of invasive disease, giving an upgrade rate to malignancy of 2.4%. Upgrade to other high‐risk lesions (atypical lobular and ductal hyperplasia and lobular carcinoma in situ) was demonstrated in 15 cases (12.1%). Benign papilloma was confirmed in 100 cases (81.5%), and 6 (4.8%) had no residual papilloma found on final excision. Twelve patients (8.7%) were managed conservatively. Of those, one later went on to develop malignancy. Patients with a diagnosis of benign papilloma without atypia on core biopsy have a low risk of upgrade to malignancy on final pathology, suggesting that observation may be a safe alternative to surgical excision. Further research is warranted to determine which patients can be safely managed conservatively.  相似文献

OBJECTIVE: Lung biopsy is associated with substantial mortality rates. We reviewed our experience with this operation, primarily in patients with immunocompetence, to determine whether the results justify the continued performance of this procedure. METHODS: We conducted a retrospective review of all diagnostic lung biopsies performed at 3 university-affiliated hospitals between July 1, 1992, and December 31, 1998. RESULTS: There were 75 patients: 25 patients were treated electively, 17 were treated on an urgent basis, 27 patients on an emergency basis, and the urgency was unclear in 6 patients. Significant beneficial therapeutic changes were made in 15 of 25 elective procedures (60%), in 16 of 17 urgent procedures (94%), and in 11 of 27 emergency procedures (41%; P =.001). Significant beneficial therapeutic changes consisted of immunosuppression in 13 of 15 (87%) patients treated on an elective basis, in 9 of 16 (56%) treated on an urgent basis, and in 9 of 11 (82%) treated on an emergency basis in whom therapy was altered (P =.14). Operative death was 0 of 25 for elective operations (0%), 3 of 17 for urgent operations (18%), and 14 of 26 for emergency operations (54%). Multivariable analysis of operative death showed urgency to be the only significant predictor of death (P =.002). CONCLUSIONS: In patients with immunocompetence, elective and urgent lung biopsies have acceptable operative mortality rates and frequently result in important beneficial therapeutic changes. Consequently biopsies are appropriate in these patients. Emergency biopsies are associated with high operative mortality rates and rarely result in a therapeutic change other than immunosuppression. These patients should not undergo lung biopsy if they are in stable condition and should be treated empirically with immunosuppression without operation if their condition is deteriorating.  相似文献

INTRODUCTION: Most surgical wounds are closed primarily, but some are allowed to heal by secondary intention. This usually involves repeated packing and dressing of the raw wound surfaces. Although the long-term care of such wounds has devolved to the care of nurses in the community or out-patient setting, the initial wound dressing or cavity packing is done by the surgeon in the operating theatre. Many surgeons are unaware of the growth of the discipline of wound care, and still use traditional soaked gauze for dressing and packing open surgical wounds and cavities. RESULTS: This review summarises the some of the modern alternatives available and the evidence--or the lack of it--for their use in both the acute and chronic setting.  相似文献

The diagnostic accuracy of computed tomography in treatment of bullous disease as the most frequent cause of recurrent spontaneous pneumothorax was 55.5%, while that of roentgenography was 16%. The recovery of patients with recurrent spontaneous pneumothorax treated by active surgical measures takes place in 85% of cases, while with drainage of the pleural cavity--in 65%.  相似文献

Minimal head injury: is admission necessary?   总被引:3,自引:0,他引:3  
The records of 138 patients admitted a Glasgow Coma Score (GCS) of 14 or 15 following head injury were reviewed to assess the need for hospital observation and to determine whether obtaining a normal computerized tomography (CT) scan in the emergency department could have avoided admission. GCS was 15 in 103 patients (74%) and 14 in 35 (26%). Eighty-three patients were admitted for their head injury alone, and 55 had other injuries but would have required admission for their head injury. Loss of consciousness was documented in 51 per cent and suspected in another 29 per cent and was distributed equally regardless of GCS. Seven per cent (5/71) of skull x rays were positive and were associated with CNS pathology in three patients. Skull x rays in an additional four patients with positive CT findings were negative including a patient with an epidural hematoma (EDH). Seventeen per cent (13/75) of CT scans were positive (contusions 5, subdural hematoma 3, subarachnoid hemorrhage 2, edema 2, EDH 1). Only the patient with the EDH required operative treatment. No patient with a normal CT scan went on to develop any neurosurgical problems, and 78 per cent of the patients admitted with isolated head injuries were discharged within 48 hours. Significant CNS pathology does occur following "minimal" head injuries. Skull x rays are not helpful. The use of CT scanning appears to triage those patients requiring admission and in hospital observation.  相似文献

Informed consent plays a pivotal role in human clinical research. It serves as a marker for the subject's comprehension of all the pertinent elements of the study. It is also a pledge by the investigator that during the trial, the rights and safety of the subject will be protected. Informed consent attempts to ensure that ethical behaviour will be upheld throughout the study. However, obtaining informed consent from certain vulnerable populations is a challenge, and thus warrants improvement. While informed consent is mandated for almost all clinical trial involving human subjects, there are situations of emergency research and trials with minimal risk that call for a waiver of the consent.  相似文献

Recent recommendations from the U.S. Preventative Services Task Force suggest that screening mammography for women should be biennial starting at age 50 years and continue to age 74 years. With these recommendations in mind, we proposed a study to evaluate women at our institution in whom breast cancer is diagnosed within 1 year of a previously benign mammogram. A retrospective chart review was performed over a 4-year period. Only patients who had both diagnostic mammograms and previous mammograms performed at our institution and a pathologic diagnosis of breast cancer were included. Benign mammograms were defined as either Breast Imaging Reporting And Data System 1 or 2. Analysis of the time elapse between benign mammogram and subsequent mammogram indicative of the diagnosis of breast cancer was performed. A total of 205 patients were included. The average age was 64 years. From our results, 48 patients, 23 per cent of the total, had a documented benign mammogram at 12 months or less before a breast cancer diagnosis. One hundred forty-three (70%) patients had a benign mammogram at 18 months or less prior. This study raises concern that 2 years between screening mammograms may delay diagnosis and possible treatment options for many women.  相似文献
