Sutures may cause endothelial trauma and occlusion. The vascular clip system (VCS) clip applier may minimize endothelial injury. Fourteen carotid arteries of nine adult rabbits were transected and re-anastomosed with either #7-0 polypropylene (Group I, n=8) or VCS clips (Group II, n=6). The animals were sacrificed at 1, 3, 8, 14, and 30 days postoperatively. The operation time and bleeding amount were checked for each anastomosis. Carotid angiograms, photography, H&E staining and scanning electron microscopy (SEM) were performed. Fibrin and thrombus, inflammatory cell infiltration, endothelial disruption, luminal distortion, fibrosis, and wall thickening were compared. The luminal diameter was greater in group II. There were minimal differences in thrombosis, wall thickening and fibrosis between the two groups. However, fibrin, inflammatory cell infiltration, multinucleated giant cell formation, endothelial disruption, and luminal distortion were greater in group I. On SEM, group I showed trans-mural penetration. In contrast, group II showed suture margin eversion and no transmural penetration. Stenosis was greater in group I than in group II on carotid angiogram. The operation time was shorter in group II than in group I, i.e. 5+/-1.4 min vs. 11+/-3.8 min, respectively. The current data showed similar or superior results with VCS clips in comparison to conventional suturing with polypropylene.

2.The invention and application of the vaginal suturing-aid apparatus.
Chinese Journal of Medical Instrumentation 2002;26(4):296-297
We have invented a barrel-shape suturing-aid apparatus with a light source on one side and a trapzoid cranny for suturing on the other side. There are many advantages proved by clinical practices in applying the suturing-aid apparatus: 1. to increase the suturing speed and relieve the pains of patients; 2. to avoid the infection of HBV by blood and crossinfection; 3. to improve the illumination condition and avoid no suturing of the hurt tissue.

Journal of Korean Medical Science 2006;21(6):1033-1036
This study was conducted to evaluate the mid-term results of cervical esophagogastric anastomosis using a side-to-side stapled anastomosis method for treatment of patients with malignant esophageal disease. A total of 13 patients were reviewed retrospectively from January 2001 to November 2005 who underwent total esophagectomy through a right thoracotomy, gastric tube formation through a midline laparotomy and finally a cervical esophagogastric anastomosis. Average patient age was 62.6 yr old and the male to female ratio was 11:2. The mean anastomosis time was measured to be about 32.5 min; all patients were followed for about 22.8+/-9.9 months postoperatively. There were no early or late mortalities. There were no complications of anastomosis site leakage or conduit necrosis. A mild anastomotic stricture was noted in one patient, and required two endoscopic bougination procedures at postoperative 4th month. Construction of a cervical esophagogastric anastomosis by side-to-side stapled anastomosis is relatively easy to apply and can be performed in a timely manner. Follow up outcomes are very good. We, therefore, suggest that the side-to-side stapled anastomosis could be used as a safe and effective option for cervical esophagogastric anastomosis.
