腔内三重双J管引流技术治疗输尿管狭窄

目的探讨腔内三重双J管引流技术治疗输尿管狭窄的可行性. 方法 2000年3月～2003年6月,对27例输尿管狭窄采用输尿管腔内置入3根相同大小的双J管引流,术后留置10～12周. 结果 27例随访2～24个月,平均18个月.26例拔管后无腰胀、发热等症状.IVP示引流通畅,患肾积水排空好,无输尿管狭窄.1例术后6个月复查IVP,肾积水仍无改善,改开放手术.本组治疗成功率96%(26/27). 结论腔内三重双J管引流技术治疗输尿管狭窄可行.     

低位直肠癌保肛手术后发生吻合口漏的原因及处理

目的：探讨低位直肠癌保肛术后吻合口漏的原因及合理有效的防治方法。方法：对我院近10年来出现的低位直肠癌全系膜切除低位吻合手术后吻合口漏的发生及治疗情况进行回顾性分析。对吻合口漏的患者采用手术及保守治疗（骶前双腔管冲洗引流加肛管引流）。结果：共行低位保肛手术348例,术后发生吻合口漏11例,吻合口漏的发生率为3.2%。患者的年龄、吻合技术和肿瘤组织学分型与吻合口漏的发生无关。而患者的性别、肿瘤的大小与吻合口漏的发生密切相关（P〈0.05）。11例患者中有3例行手术治疗（HA手术）,8例采用保守治疗后均痊愈出院,吻合口漏发生至出院时间平均为10～15d。结论：充分的术前准备和良好的吻合技术是防止吻合口漏发生的关键。正确判断吻合口漏的发生及采用正确的处理方法是治疗的前提,双腔引流管加肛管引流是保守治疗吻合口漏的有效方法。     

Closed suction drainage after orthopaedic surgery: evidence versus practice

Abstract Closed suction drainage systems are commonly used in orthopaedic surgery, particularly in joint arthroplasty. The rationale for the use of drains is a theoretical reduction of wound haematomas and infection. However the benefit of using drains after total hip or knee arthroplasty is controversial. Several reports have shown that the use of drains does not reduce infection and morbidity and is an unnecessary and potentially dangerous practice. In fact most studies highlighted that at best their use appears to make no difference to important clinical outcomes. Recently a metaanalysis raised the question about the usefulness of closed suction drainage again, concluding that it has no major benefits. The purpose of this study was to review the evidences available concerning the utility of closed suction drainage outlining that this practice is not supported by clinical evidence.

A comparative study on therapeutic method of traumatic epidural hematoma

Objective： To explore the therapeutic methods, surgical indications and clinical practice of minimally invasive surgery on traumatic epidural hematoma （EDH）. Methods： Retrospective study was made on 135 patients with traumatic EDH admitted into our hospital from June 2002 to August 2005. Sixty-five patients were treated with mini-invasive negative pressure drainage （treatment group）, 70 patients with comparable condition used traditional craniotomy （control group ）. The mean time of operation, average days in hospital, expenditure and prognosis of two groups were recorded and analyzed. Results： There was no significant difference in therapeutic efficacy between two groups. Patients in treatment group had a shorter hospital stay and less expenditure than those in control group. Conclusion： Mini-invasive negative pressure drainage is simple, effective, economical and applicable to some traumatic EDH patients.     

Relative risks of ventriculostomy infection and morbidity

Summary Ventricular catheter placement is a common procedure for the management of increased intracranial pressure. Hypotheses regarding the etiology of infection of catheters center on two alternative assumptions: 1) contamination leading to infection occurs at the time of catheter insertion, implying that catheter duration has minimal effect on infection risk; and 2) infection of catheters derives from catheter contamination after insertion, suggesting that duration of catheter use may significantly affect infection risk.We have studied the relative complication rate of ventricular catheter insertions using a retrospective approach (n=161 patients and 253 catheter insertion procedures). The overall infection rate was 4.1%, but the daily infection hazard increased exponentially with time, to a maximum daily rate of 10.3% by day 6 of catheter insertion. This increasing risk appears most consistent with the second hypothesis. The risk of non-infectious complications was 5.6%, including hemorrhagic occurrences and misplacement severe enough to require a new catheter insertion. The daily hazard of infection approximately equalled the non-infectious risk of routine catheter replacement by day 5.Additional prospective data on the daily risk of CSF infection and the appropriateness of antibiotic prophylaxis either at the time of ventricular catheter insertion or continued through the catheter's-presence may be required to both definitively identify which hypothesis of infection risk is correct and whether antibiotics can significantly ameliorate this risk.
