Colonic anastomosis with the nickel-titanium temperature-dependent memory-shape device

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.

Intraocular Lens Implantation: A Review

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.     

Ultrasound demonstration of clip migration to Skin within 6 weeks of 11-gauge vacuum-assisted stereotactic breast biopsy

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.

Efficacy of Absorbable Clips Compared with Metal Clips for Cystic Duct Ligation in Laparoscopic Cholecystectomy

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.

结直肠局限病变术前定位微创手术治疗探讨

【目的】探讨结直肠局限性病变术前钛夹定位、小切口手术的优越性。【方法】经内镜在结肠病变旁置钛夹，X线下腹壁定位，66例与传统定位法58例进行临床疗效对比分析。【结果】66例钛夹定手术切口小（5～10cm即可），缩短手术时间（1—2h），明显优于传统定位方法。【结论】钛夹术前定位法指导结直肠外科开展微创手术治疗作用明显优于各种传统定位方法，是一种国内尚无报道、有效的，值得推广的新方法。     

Small bowel obstruction at a Filshie clip applicator port site

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.
