Purpose: We examined muscle strength and walking ability after hernia repair to compare the effects of laparoscopic hernioplasty and
conventional repair.
Methods: Twenty-seven patients with primary inguinal hernias were randomly divided into two groups according to the surgical procedure:
15 patients were treated with laparoscopic hernioplasty and 12 with conventional repair. Two types of muscle testing around
the inguinal region, one by manual examination and one using a musculator, were done preoperatively and 1 week postoperatively.
Walking exercise tests were performed at the same time as muscle testing.
Results: Manual examination showed that the postoperative muscle strength of the iliopsoas muscle was decreased in six patients from
the conventional repair group, but not in any of those from the laparoscopic hernioplasty group. The musculator showed decreased
strength of the iliopsoas muscle after conventional repair, but not after laparoscopic hernioplasty. The walking exercise
test showed that conventional hernia repair influenced walking.
Conclusion: A decline in muscle strength of the iliopsoas muscle and walking ability was evident after conventional repair, but not after
laparoscopic hernioplasty. Thus, laparoscopic hernioplasty is superior to conventional repair from the perspective of muscle
testing and walking ability.

对CT和手术证实的三组颅内占位病变测试脑干听觉诱发电位(BAEP)和正中神经短潜伏期体感诱发电位(SLSEP)。16例病程中出现小脑幕裂孔下疝(DTH)的幕上病变,BAEP和SLSEP均异常。36例出现假性定位体征的幕上病变,BAEP异常35例,SLSEP异常33例。BAEP异常主要为v波峰潜伏期(PL),Ⅰ~Ⅴ、Ⅲ~Ⅴ峰间潜伏期(IPr)延迟;SLSEP以P(14),波异常及N(13)~N(20)IPL延迟为主。14例幕下病变所致的枕骨大孔疝,BAEP和SLSEP均异常,其中6例病程中复查了诱发电位。结果提示,BAEP和SLSEP可作为DTH患者脑干功能损害的客观指标,且可用于评价未出现DTH患者的脑干功能。BAEP和单次SLSEP测试对枕骨大孔疝的诊断意义不大,后颅窝病变进行SLSEP动态观察,对枕骨大孔疝的早期诊断有价值。 相似文献

Summary In this report we describe 3 patients with syringomyelia in association with tumours of the posterior fossa. In each patient the syrinx was demonstrated on pre-operative magnetic resonance imaging (MRI). After total or partial removal of the tumour the syrinx collapsed. It is concluded that the pathogenesis of syrinx formation in this entity requires interference with normal cerebrospinal fluid (CSF) flow at the foramen magnum. We suggest that the obstruction to the flow of CSF causes alterations in the passage of extracellular fluid (ECF) in the spinal cord which lead to syringomyelia. 相似文献

Open mesh versus non-mesh repair of groin hernia meta-analysis of randomized trials leased on individual patient data 总被引:1,自引:1,他引:0
Abstract
Background. The EU Hernia Trialists Collaboration was established to provide reliable evaluation of newer methods of groin hernia repair.
It involved 70 investigators in 20 countries.
Materials and methods. Twenty eligible trials (5016 participants) of open mesh vs. non-mesh groin hernia repair were identified. Meta-analysis was
performed using raw individual patient data where possible.
Results. Fewer hernia recurrences were reported after mesh repair. There were no clear differences between mesh and non-mesh groups
in complications. Overall, those in the mesh groups had a shorter hospital stay, quicker return to usual activities and less
frequent persisting pain, but individual trial results varied.
Conclusions. The review provides strong evidence that open mesh repair is associated with a reduction in the risk of recurrence of between
50% and 75%. There is also some evidence of quicker recovery and of lower rates of persisting pain following open mesh repair.

Preliminary experience with new bioactive prosthetic material for repair of hernias in infected fields 总被引:15,自引:5,他引:10
Surgisis (Cook Surgical, Bloomington, Ind., USA) is a new four-ply bioactive, prosthetic mesh for hernia repair derived from
porcine small-intestinal submucosa. It is a naturally occurring extracellular matrix which is easily absorbed, supports early
and abundant new vessel growth, and serves as a template for the constructive remodeling of many tissues. As such, we believe
that Surgisis mesh is ideal for use in contaminated or potentially contaminated fields in which ventral, incisional, or inguinal
hernia repairs are required. From November 2000 through May 2002, 25 patients (11 male, 14 female) underwent placement of
Surgisis mesh for a variety of different hernia repairs. A total of 25 hernia repairs were performed in our patient population.
Fourteen procedures (56%) were performed in a potentially contaminated setting (i.e. with incarcerated/strangulated bowel
within the hernia or coincident with a laparoscopic cholecystectomy/colectomy). Eleven repairs (44%) were performed in a grossly
contaminated field, including one in which an infected polypropylene mesh from a previous inguinal hernia repair was replaced
with Surgisis and one in which necrotic bowel was discovered within the hernial sac. Median follow-up was 15 months with a
range of 1–20 months. Of the 25 total repairs, there was one wound infection complicated by enterocutaneous fistula in a patient
originally operated on for ischemic bowel. The fistula was in a location independent of the Surgisis mesh. There were no mesh-related
complications or recurrent hernias in our early postoperative follow-up period. Surgisis mesh appears to be a promising new
prosthetic material for hernia repair, especially in contaminated or potentially contaminated fields. Obviously, long-term
follow-up is still required.

Blood gas analysis can be used to reliably predict outcome in infants with congenital diaphragmatic hernia (CDH) both before and after surgical repair, providing these values are indexed to some measurement of alveolar ventilation. Until recently there has been difficulty in interpreting some of the published data because of differing sampling sites and the fact that ventilatory parameters, which have major influences on all blood gas values in this anomaly, were not included. Application of this information enables us to identify infants with similar degrees of severity of CDH in order to evaluate the efficacy of novel forms of therapy and to determine whether they represent a genuine advance in management where more conventional forms of treatment have failed. 相似文献

回顾5例由于神经根变异或特殊类型椎间盘突出引起的腰腿痛病人,对其病理及术中处理做了介绍,认为由于神经根的解剖变异,更容易受到椎间盘突出的卡压。手术中如临床症状符合椎间盘突出症,而预定探查间隙未发现突出物,或与临床症状不符者,应根据神经根激惹及松紧程度,扩大探查范围,查明造成疼痛的原因,避免二次手术。 相似文献

Long-term result and current status of the Lichtenstein open tension-free hernioplasty 总被引:12,自引:6,他引:6
Summary The tension-free hernioplasty project began in 1984 at the Lichtenstein Hernia Institute. The method consists of complete reinforcement of the inguinal floor with a large sheet of mesh, with adequate mesh tissue interface beyond the boundary of the inguinal floor and creation of a new internal ring made of prosthesis. The preliminary report of this operation was published in 1989, with no recurrence at that point in time. Shortly after the submission of the report, several recurrences were encountered. Based on the lesson learned from those recurrences, the operation was slightly modified and reported in 1991 [Amid 1993]. Since then, the Lichtenstein technique has gained world-wide popularity. Outcome measures identical to ours and other authors have been achieved by even those surgeons who have no special interest or expertise in herniology. The purpose of this article is to report the current state of the open tension-free hernioplasty for the repair of primary and recurrent inguinal hernias. 相似文献
