Hem-o-lok结扎锁在后腹腔镜肾切除术肾蒂血管处理中的应用 总被引:1,自引:0,他引:1
目的:探讨后腹腔镜肾切除术中应用Hem-o-lok结扎锁处理肾蒂血管的价值。方法:我们为63例患者行后腹腔镜肾切除术并采用Hem-o-lok结扎锁处理肾蒂血管,其中肾动脉近端用大号Hem-o-lok2枚结扎,远端用2枚钛夹夹闭后剪断,肾静脉用加大号Hem-o-lok近端2枚、远端1枚结扎后剪断。结果:本组手术时间90~255min,平均135min;出血量20~180ml,平均45ml;术后住院时间5~8d;术中肾蒂血管处理满意,术中、术后未发生严重并发症。结论:腹腔镜肾切除术中用Hem-o-lok结扎锁分别处理肾动静脉,安全可靠,经济实用,值得临床推广应用。 相似文献

The OTSC® Proctology clip system for anorectal fistula closure: the ‘Anal Fistula Claw’: Case report
《Minimally invasive therapy & allied technologies》2013,22(4):307-312
AbstractSurgical treatment of high or complex anal fistulas often renders unsatisfying results. This is the report of the first successful closure of such anal fistula using a special Nitinol clip and applicator, the OTSC® Proctology system (Ovesco AG, Tuebingen, Germany): A 54-year old female patient was suffering from a high transsphincteric anal fistula. After seton drainage of the fistula for ten weeks, the fistula track was debrided using a special fistula brush. After transanal clip release from the applicator, the internal fistula opening was adequately closed by the clip. Eight months after clip closure the fistula had healed and the clip was removed using the OTSC® Proctology Clip Cutter. Fistula closure using the OTSC® Proctology system represents a promising sphincter-preserving minimally invasive procedure. 相似文献

Colonic anastomosis with the nickel-titanium temperature-dependent memory-shape device 总被引:9,自引:0,他引:9
BACKGROUND: This study was prompted by our successful experience with a compression anastomosis clip (CAC) in an animal model. METHODS: The study sample included 20 patients scheduled for colonic resections, of whom 10 underwent anastomosis with the CAC and 10 with staplers. RESULTS: Neither group had anastomotic or other complications, except for 1 patient in the CAC group in whom a subphrenic infected hematoma developed after left hemicolectomy with splenectomy. CONCLUSIONS: Our study demonstrates that this CAC is safe and simple to use, coming close to the "no touch surgery concept" and is of low cost compared with the staples used today. 相似文献

Intraocular lens implantation has been developing over the past 15 years in Europe and is now becoming popular in the United States. Lens materials and designs as well as surgical techniques are still being evaluated. The overall results are excellent, with a small increase in complications being the price paid for a dramatic increase in visual rehabilitation. 相似文献

A 39-year-old woman underwent 11-gauge vacuum-assisted stereotactic biopsy of a cluster of calcifications at the 5 o'clock location in the left breast. Initial clip placement was confirmed by mammograms to be at the biopsy site. The patient experienced episodic minimal bleeding at the skin entry site when she went home. The patient presented 6 weeks later with a history of progressive discomfort and lump at the stereotactic breast biopsy scar site. Ultrasound confirmed clip migration to the skin incision site. The clip was removed percutaneously by the radiologist, relieving the patient of her symptoms. 相似文献

Purpose: This study was conducted to examine the usefulness and safety of absorbable clips in laparoscopic cholecystectomy (LC).
Methods: We retrospectively compared the clinical data of 328 patients who underwent LC using absorbable clips for cystic duct ligation
and 444 patients who underwent LC using metal clips for cystic duct ligation.
Results: The mean operative time in the absorbable clip group was significantly shorter than that in the metal clip group. The mean
intraoperative blood loss and hospital stay were not significantly different between the two groups. The rate of conversion
to open laparotomy in the absorbable clip group was significantly higher than that in the metal clip group, at 6.7% vs 2.3%, respectively. The most common reason for conversion was difficult adhesions and inflammation around the gallbladder.
The morbidity of the metal clip group was significantly higher than that of the absorbable clip group, at 8.4% vs 4.0%, respectively. The incidence of major postoperative complications requiring laparotomy did not differ between the two
groups. There were no deaths in the absorbable clip group, but 1 of the 444 patients (0.23%) in the metal clip group died
from disseminated intravascular coagulation on postoperative day 3.
Conclusion: The results of this study suggest that absorbable clips are as safe and effective as standard metal clips for vessel and
duct ligation in LC.

Laparoscopic Filshie clip sterilisation remains a common method of permanent female contraception. Worldwide, approximately
190 million couples use tubal occlusion (United Nations world population monitoring. United Nations, 2002). Trocar site incisional
hernia has been reported as a complication of laparoscopic surgery where a 10-mm port was employed (Tonouchi et al. Arch Surg
139(11):1248–1256, 2004). It is common practice to repair port sites of 10 mm or more to prevent herniation. Port sites of
5 mm are not routinely repaired by most surgeons because it is thought that such iatrogenic fascial defects are not large
enough to predispose to hernia (Reardon et al. J Laparoendosc Adv Surg Tech A 9(6):523–525, 1999). We report a rare case of
early Filshie clip applicator port site intestinal obstruction following laparoscopic sterilisation. The mechanism of hernia
formation and a preventive strategy are discussed. 相似文献
