Toward a sutureless vasovasostomy: use of biomaterials and surgical sealants in a rodent vasovasostomy model.

PURPOSE: With 500,000 to 800,000 vasectomies performed annually and a reversal rate of 3% to 8% vasectomy reversal has become a commonly performed procedure. Two-layer microsurgical vasovasostomy remains the gold standard for surgical reconstruction of the vas. However, this procedure is technically demanding and time-consuming. We determined the ability of biomaterials and surgical sealants to decrease the number of sutures used, enhance anastomosis watertightness and decrease operative time. MATERIALS AND METHODS: Adult male Wistar rats underwent vasectomy 2 weeks prior to vasovasostomy. Standard 2-layer microsurgical repair was performed in control animals. Experimental groups underwent 3-suture mucosal approximation and then completion of the anastomosis with a biomaterial membrane and/or synthetic sealant. The rats were sacrificed 9 weeks after vasovasostomy. Anastomotic patency was assessed functionally by the presence of motile sperm in the vas distal to the testes and anastomosis, and mechanically by methylene blue vasogram. The presence and size of sperm granulomas were also recorded. RESULTS: Microsurgical vasovasostomy required significantly less time when biomaterial (42.7 minutes) or sealant (40 minutes) was used compared to the standard sutured group (102.5 minutes, each p < 0.001). There was no difference in patency between the standard sutured and biomaterial groups (90% vs 92%). Patency was significantly lower in the sealant groups, that is 70% in the suture, biomaterial and sealant group, and 75% in the suture and sealant group. The biomaterial group had only 1 sperm granuloma in 12 procedures, which was significantly better than the 7 in the control group (p <0.001). CONCLUSIONS: Using a biomaterial wrap during vasovasostomy resulted in significantly decreased operative time and fewer sperm granulomas than in the control group. Sealants were not effective. Biomaterial wrap may support vasovasostomy and by decreasing leakage improve the outcome.

Sutureless intestinal plication.

BACKGROUND: Adhesions form between damaged mesothelial surfaces and can cause recurrent small bowel obstruction. Repeat laparotomies may be required in some cases, which can be associated with significant morbidities. METHODS: A technique is described for plication of the small bowel in an orderly manner with the use of two silicone indwelling urinary catheters. CONCLUSIONS: This plication technique, a modification of the Noble and Childs-Phillips operations, is effective, safe, quick and cost-effective.

Inadvertent atrial location of a sutureless epicardial pacemaker electrode.

A 70-year-old woman had an epicardial pacing system implanted after transvenous right ventricular endocardial pacing resulted in cardiac perforation. At the time of revision of the epicardial system for pacing failure, it was noted that one of the bipolar epicardial electrodes was pacing atrial tissue. The differential diagnosis of this unusual finding is discussed and recommendation urged for systematic analysis of pacing system function at the time of implant, in order to avoid inadvertent electrode placement.

Experimental and clinical study of a new permanent myocardial atrial sutureless pacing lead.

A new permanent lead has been developed for atrial epicardial use. Early clinical evaluation (26 human implants) following thorough canine studies indicates that the new lead is safe, effective, and reliable. Canine thresholds and P-wave amplitudes as a function of implant time are similar to those of transvenous atrial "J" leads. Human thresholds at implant are higher than canine, but change less with time. Implant and acute repositioning were found to be easy. There have been no lead-related operations.

Sutureless repair of postinfarction cardiac rupture.

A 62-year-old female with a history of progressive angina experienced an acute myocardial infarction. Seven days later, cardiac rupture ensued. She underwent surgical repair without the aid of extracorporeal circulation. A Teflon patch was glued over the myocardial tear with medical adhesive. She recovered and is leading a normal life, 15 months after surgery.

Successful management of a postinfarction left ventricular rupture using a sutureless technique with concomitant myocardial revascularization.

We present a case of left ventricular (LV) rupture that occurred on the second day after inferolateral myocardial infarction (MI). An aggressive diagnostic approach with rapid coronary angiography prior to surgical repair provides a benefit characterized postoperatively by complete recovery of myocardial contractility in the akinetic infarcted area. We believe that coronary artery disease associated with subacute ventricular rupture may, in fact, be better investigated and simultaneously treated under a protocol of early surgical repair.

Adal-1 bioadhesive for sutureless recession muscle surgery: a clinical trial.

AIMS: To evaluate the efficacy and biotolerance of the Adal-1 adhesive for muscle sealing in strabismus surgery. METHODS: 27 eyes were included in the study: 17 in the control group and 10 in the study group. Surgery was performed on the recession of the horizontal rectus muscles. In the control group the muscle was joined to the sclera by a Vicryl 7/0 suture. In the study group, the Adal-1 adhesive was used instead. The efficacy of the sealing of the muscle to the sclera and the biotolerance of the surrounding tissues were evaluated. RESULTS: The muscular recession in the control group was 8.17 (SD 2.38) with displacement of the sealing point of 0.02 (1.7) mm. In the group sealed with adhesive, the muscular recession was 9.09 (3.08) and the displacement was 0.15 (1.56) mm, with no significant differences between the techniques (p<0.05). The inflammation of the surrounding tissues in the immediate postoperative period was greater with the suture technique (p>0.05), but there were no differences in the other postoperative periods (Mann-Whitney U test). CONCLUSION: Adal-1 was an effective and safe alternative to sutures in muscle recession for strabismus surgery in this study.
