人体颈部位于头与胸部之间,呈圆颈筒形,连接头、躯干和上肢。颈部的正前方有呼吸道及消化道的上段,正后方有颈椎及上段胸椎,两侧有大血管及神经,颈根部胸膜顶和肺尖,并有斜行的大血管和神经[1]。颈部肌肉组织较薄,除有丰富的神经、大血管外,还有甲状腺等重要器官。受伤后容易引起大出血,重者喉肌痉挛,气管堵塞以至危及生命。必须迅速采取急救措施,才能脱离危险。我科2005年3月-2014年3月收治了36例颈部切割伤患者,经积极抢救、治疗及精心护理,效果满意。现报告如下。 相似文献

BackgroundIn megaprosthetic knee replacement, surgeons use cutting guides that depend on anatomLevel of evidenceical references to determine the ideal cutting plane alignment. In this work, we investigated the accuracy of using femoral cortical surfaces and tibial canal portions as the references. The study aims to improve the design and use of the cutting guides.ResultsAt the central femoral region, on average, both lateral and medial cortical surfaces give accurate alignment of the ideal cutting plane (0.6° and 0.8°, respectively), with no significant difference (p > 0.01). At the distal region, the lateral cortical surface gives significantly better alignment compared to the medial cortical surface (p < 0.01), but not as accurate (1.4°) as in the central region. For tibia, the central tibial canal gives significantly accurate alignment of the ideal cutting plane (−0.3°) on average, compared to the proximal tibial canal (p < 0.01).ConclusionsFor a femoral cut, both lateral and medial cortical surfaces are the best anatomical references, but only at the central region. For a tibial cut, the central anatomical axis is the best reference.

Abstract.
Background:
Cutting setons have been used in complicated perirectal
sepsis with good effect, although there is a moderately high
incidence of fecal leakage after their use. The aim of this
study was to compare a modified cutting seton, which repaired
the internal anal sphincter muscle and re-routed the seton
through the intersphincteric space, with a conventional cutting
seton.
Methods:
A total of 34 patients were randomized between 1998 and
2002. They were prospectively assessed by continence score and
anorectal manometry, and for anal function, clinical sepsis and
fistula recurrence.
Results:
There was no difference in postoperative continence score,
incidence of recurrent fistula or healing time between groups
after a mean follow-up of 12 months. Resting anal manometric
pressures and vector volumes were consistently higher with the
modified seton (although not statistically significant), as was
the area under the inhibitory curve during elicitation of the
rectoanal inhibitory reflex across the full sphincter length.
(p<0.05).
Conclusion:
A larger prospective study of internal anal
sphincter-preserving seton use in cryptogenic high
transshincteric fistula-in-ano appears justified. 相似文献

Background We report one safe and standardized technique of seton placement and management.Conclusions A simplified way to manage cutting setons helps to minimize manipulation and may reduce pain. In most patients our technique can be used with no additional anesthesia and in an outpatient setting.An invited commentary on this paper is available at 相似文献

Risk factors for bleeding after endoscopic mucosal resection 总被引:11,自引:0,他引:11
Shiba M Higuchi K Kadouchi K Montani A Yamamori K Okazaki H Taguchi M Wada T Itani A Watanabe T Tominaga K Fujiwara Y Hayashi T Tsumura K Arakawa T 《World journal of gastroenterology : WJG》2005,11(46):7335-7339
AIM: To clarify the risk factors for bleeding after endoscopic mucosal resection (EMR). METHODS: A total of 297 consecutive patients who underwent EMR were enrolled. Some of the patients had multiple lesions. Bleeding requiring endoscopic treatment was defined as bleeding after EMR. Odds ratios (OR) with 95% confidence intervals (CI), calculated by logistic regression with multivariate adjustments for covariates, were the measures of association. RESULTS: Of the 297 patients, 57 (19.2%) patients with bleeding after EMR were confirmed. With multivariate adjustment, the cutting method of EMR, diameter, and endoscopic pattern of the tumor were associated with the risk of bleeding after EMR. The multivariate-adjusted OR for bleeding after EMR using endoscopic aspiration mucosectomy was 3.07 (95%CI, 1.59-5.92) compared with strip biopsy. The multiple-adjusted OR for bleeding after EMR for the highest quartile (16-50 mm) of tumor diameter was 5.63 (95%CI, 1.84-17.23) compared with that for the lowest (4-7 mm). The multiple-adjusted OR for bleeding after EMR for depressed type of tumor was 4.21 (95%CI, 1.75-10.10) compared with elevated type. CONCLUSION: It is important to take tumor characteristics (tumor size and endoscopic pattern) and cutting method of EMR into consideration in predicting bleeding after EMR. 相似文献

Results of a Peripheral Cutting Balloon Prospective Multicenter European Registry in Hemodialysis Vascular Access 总被引:2,自引:2,他引:0
Purpose To report initial experience with the Peripheral Cutting Balloon (PCB) in treatment of failing hemodialysis shunts.
Methods A total of 190 patients (95 men, 95 women; average age 64.4 ± 11.9 years, range 32–87 years) who were treated with the PCB
for pressure-resistant stenosis, restenosis or failed percutaneous transluminal angioplasty (PTA) in the venous limb of an
arteriovenous shunt were followed in seven European centers using a simple registry. The group consisted of 109 de novo lesions
(57%) and 79 restenotic lesions (43%).
Results Technical success was achieved in 88.9% of cases. Primary patency was as follows (the results for whole group and simultaneous
results for de novo lesions and restenoses are presented): 1 month (140 patients followed): 94%, 98%, and 93%; 3 months (116
patients followed): 93%, 98%, and 92%; 6 months (40 patients followed): 85%, 92%, and 79%; 12 months (27 patients followed):
74%, 87%, and 48%. No complication occurred. Patients experienced an equal or lower level of pain during the procedure compared
with conventional PTA.
Conclusion The PCB proved to be successful in dilating pressure-resistant stenoses. We cannot conclude whether PCB angioplasty can lower
the restenosis rate in hemodialysis access lesions, but the long-term patency for de novo lesions is high. A further randomized
study is advisable. 相似文献

Setons are employed in high perianal fistulae. Our study aimed to use multiple setons in addition to a partial fistulotomy in high perianal fistulae involving the sphincter complex to combine the effects of cutting and drainage of the fistulous tract. This prospective study included 16 patients over a period of 4 years who presented with high perianal fistulae. The internal opening was identified and tract laid open till the dentate line. Four prolene threads were passed along the remainder of the tract and taken out through the external opening. One was tied tightly while the others were tightened every 7 days. No patients developed major faecal incontinence. Fistula recurred in one patient within a year and one patient had occasional incontinence to flatus. Multiple setons after partial fistulotomy is an effective treatment for high anal fistulae with low incidence of incontinence and recurrence and adequate patient satisfaction. 相似文献
