Background: There is a growing interest in the use of local anaesthesia for inguinal hernia repair. It certainly seems to
be an acceptable alternative for the elderly. Supporting intravenous sedation, however, still requires monitoring, anaesthetic
personnel and some preparations for the patient. Therefore we set up a feasibility study of hernia repair under local anaesthesia
without intravenous sedation or monitoring in elderly patients. Method: A total of 62 patients (aged 65 years or more) with
unilateral inguinal hernia received a Mesh Plug Repair. Prospectively collected data included procedure-related complications
and information on pain and quality of life as measured by Short Form 36. Results: No procedure-related complications were
noted. Comparing the preoperative scores, the SF-36 on day 14 (n=61) did not differ significantly. After a median follow-up of ten months (n=54), significantly higher scores were found for scales of physical and emotional role and pain (all p<0.05). Twenty-two patients reported some form of pain (40.7%). 94.4% of the patients would recommend the procedure when asked.
Conclusion: The results of this study indicated that Mesh Plug Repair performed under unmonitored local anaesthesia with no
intravenous sedation is a feasible alternative for elderly patients. It has advantages for the medical organization without
disadvantages for the patient. 相似文献

目的分析肺癌骨转移引起腰腿痛症状导致误诊的原因及教训。方法对1例误诊为腰椎间盘突出症、腰臀部慢性软组织损害的肺癌骨转移致腰腿痛患者的诊疗过程结合文献进行综合分析。结果肺癌骨转移所致腰腿麻痛症状是因受累椎体发生溶骨性破坏或楔形变,对应椎管位置狭窄,肿瘤侵犯骨皮质或软组织肿块压迫刺激脊髓和神经根而引起,本病误诊的主要原因是病史询问不详,查体简单、粗疏,未做针对性强的影像学检查。结论仔细询问病史,认真查体,与早期行针对性强的影像学检查相结合,可有效降低误诊率。 相似文献

The surgical approach to ischemic mitral regurgitation with concomitant inferior left ventricular aneurysm remains uncertain
in terms of the indication for operation and the short-and long-term outcomes. We performed concomitant mitral valve repair,
left ventricular reconstruction, and aortic valve replacement on a 71-year-old male with severe ischemic mitral regurgitation,
inferior left ventricular aneurysm, and degenerative aortic regurgitation. Postoperative status was in New York Heart Association
functional class I without mitral regurgitation 8 months after operation. We discuss, and review the procedures reported in
the literature. 相似文献

Repair of large midline incisional hernias with polypropylene mesh: Comparison of three operative techniques 总被引:9,自引:0,他引:9

Polypropylene mesh is widely used for the reconstruction of incisional hernias that cannot be closed primarily. Several techniques have been advocated to implant the mesh. The objective of this study was to evaluate, retrospectively, early and late results of three different techniques, onlay, inlay, and underlay. The records of 53 consecutive patients with a large midline incisional hernia — 25 women and 28 men, mean age 60.4 (range 28–94) — were reviewed. Polypropylene mesh was implanted using the onlay technique in 13 patients, inlay in 23 patients, and underlay in 17 patients. Either the greater omentum or a polyglactin mesh was interponated between the mesh and the viscera. The records of these 53 patients were reviewed with respect to: size and cause of the hernia, pre- and postoperative mortality and morbidity, with special attention to wound complications. Patients were invited to attend the outpatient clinic at least 12 months after implantation of the mesh for physical examination of the abdominal wall. Postoperative complications occurred in 14 (26.4%) patients. The onlay technique had significantly more complications, as compared to both other techniques. Reherniation occurred in 15 (28.3%) patients. The reherniation rate of the inlay technique was significantly higher than after the underlay technique (44% vs 12%, P=0.03) and tended to be higher than the onlay technique (44% vs 23%, P=0.22). Repair of large midline incisional hernias with the use of a polypropylene mesh carries a high risk of complications and has a high reherniation rate. The underlay technique seems to be the better technique. 相似文献
