Retroperitoneal Laparoscopic Nephrectomy in Children   总被引:1,自引:0,他引:1  
Retroperitoneal pediatric laparoscopic nephrectomy is described in 3 patients requiring 3 to 5 hours with an estimated blood loss of 10 to 60 cc. The children returned to school within 7 days postoperatively. Advantages of this procedure include the avoidance of intraoperative repositioning of the patient and easy conversion to an open lumbodorsal approach, if necessary; early laparoscopic visualization of the renal artery; applicability in cases of previous abdominal surgery, and avoidance of intraperitoneal adhesion.  相似文献

Laparoscopic surgery is gaining popularity among the surgical community. While its prevalence expands, the need for reliable training and assessment tools is becoming increasingly important. Laparoscopic skills are not an innate behavior, nor can they be easily mimicked, and can only be acquired through hands-on training. A consensus exists among physicians that establishment and evaluation of technical skill in surgical training programs are inadequate and in need of improvement. A validated, reliable bench model that could train and assess could be standardized and provide numerous benefits including determination of which medical students should consider a career in surgery, valuable feedback to residents, a tracking mechanism of resident performance, a possible certification and recertification tool, and to allow for interinstitutional comparison. To this end, several potentially successful bench models testing dexterity, hand-eye coordination, and depth perception have been developed. A few models have been proven to be both valid and reliable indicators of technical skill. Although the future remains uncertain, enough groundwork has been laid to begin incorporating technical skill training and assessment into surgical training programs.  相似文献

Summary In the rat, prolonged administration of the luteinizing, hormone-releasing hormone agonist buserelin (25 μg/kg body wt/day s.c.) lowers blood estradiol, raises bone resorption, and induces osteopenia. The present study was undertaken to determine whether withdrawal of buserelin normalizes blood estradiol, slows bone resorption, and corrects buserelin-mediated osteopenia. Four groups of female rats with45Ca-labeled bones were studied: group 1A received 0.2 ml saline s.c. daily for 4 weeks; group 2A received 0.2 ml buserelin s.c. daily for 4 weeks; group 1B received 0.2 ml saline s.c. daily for 8 weeks; group 2B received 0.2 ml buserelin s.c. daily for 4 weeks followed by 0.2 ml saline s.c. daily for 4 weeks. Bone resorption was monitored by measuring urinary45Ca and hydroxyproline. The rats in groups 1A and 2A were killed after 4 weeks and those in groups 1B and 2B after 8 weeks. The mineral contents of the femoral bones and the whole skeletons were measured. Buserelin lowered blood estradiol, elevated urinary45Ca and urinary hydroxyproline, and lowered femur and total body calcium and45Ca in group 2A vs. 1A (P<0.05). By contrast all these measurements became similar in groups 2B and 1B. Thus, osteopenia generated by a 4-week period of buserelin-mediated hypo-estrogenism is reversible by withdrawing buserelin for 4 weeks. Consequently, buserelin administration and withdrawal may be used to study effects of inducing and reversing estrogen-deficiency bone loss in the rat.  相似文献

We present four cases of acute mesenteric infarction in patients with active ulcerative colitis: one presenting prior to the diagnosis of ulcerative colitis, two at the time of diagnosis, and one many years after the diagnosis had been made. Intestinal ischaemia is an important part of the differential diagnosis in patients with ulcerative colitis presenting with abdominal pain. Conversely, in patients presenting with bloody diarrhoea after mesenteric ischaemia, ulcerative colitis should be considered.  相似文献

OBJECTIVE: To determine the quality of life in individuals with corrected tetralogy of Fallot. METHODS AND SUBJECTS: Questionnaires concerning quality of life were sent to all 87 surviving patients aged between 16 and 40 years who had undergone intracardiac repair of tetralogy of Fallot and follow-up in the Wessex Cardiothoracic Unit, and to 87 age and sex matched controls, with medically treated haemodynamically insignificant ventricular septal defects. RESULTS: The only significant difference found between the cases and controls was in requirements for schooling, where those with tetralogy of Fallot were more likely to require additional educational help at school (p = 0.044). For all other aspects of quality of life examined by the questionnaire, including social and genetic history, exercise ability, and health related quality of life, no significant differences were found. Different operative techniques, such as transjunctional patching, right ventriculotomy, and previous palliative shunting, did not affect the quality of life of our population with Tetralogy of Fallot, on average twenty years after their surgery, although the range of operative techniques was limited. Neither age at surgery, nor time since surgery, was correlated with measurements of quality of life. CONCLUSIONS: Those who have undergone surgical correction of tetralogy of Fallot have a normal quality of life, with few differences compared to controls.  相似文献

Objective

We aimed to explore how patients with long-term conditions choose between available healthcare options during a health crisis.

Methods

Patients in North-West England with one or more of four long-term conditions were invited to take part in a questionnaire cohort study of healthcare use. Semi-structured interviews were conducted with a sub-sample of fifty consenting patients. Data were analysed qualitatively, using a framework approach.

Results

Patients described using emergency care only in response to perceived urgent need. Their judgements about urgency of need, and their choices about what services to use were guided by previous experiences of care, particularly how accessible services were and the perceived expertise of practitioners.

Conclusion

Recursivity and candidacy provide a framework for understanding patient decision-making around emergency care use. Patients were knowledgeable and discriminating users of services, drawing on experiential knowledge of healthcare to choose between services. Their sense of ‘candidacy’ for specific emergency care services, was recursively shaped by previous experiences.

Practice implications

Strategies that emphasise the need to educate patients about healthcare services use alone are unlikely to change care-seeking behaviour. Practitioners need to modify care experiences that recursively shape patients’ judgements of candidacy and their perceptions of accessible expertise in alternative services.  相似文献
