Resection of plantar fibromatosis with interposition of Marlex surgical mesh.

Successful surgical resection of plantar fibromatosis is often difficult because of high recurrence rates and frequent postoperative complications. In this study, two different surgical procedures, both used to excise plantar fibromatosis permanently, are compared and evaluated. These procedures are local resection of plantar fibromatosis and local resection of plantar fibromatosis with interposition of Marlex surgical mesh. A 10-year follow-up study comparing the results of both procedures is presented. Interpretation of our results indicates that recurrence of plantar fibromatosis after surgical resection can be significantly reduced by utilizing Marlex surgical mesh.

Characterization of morphologic and mechanical properties of surgical mesh fabrics.

The objective of this study is to use standard testing methods to characterize the currently available synthetic mesh fabrics in terms of their chemical, physical, mechanical, and morphologic properties. Three commonly used surgical mesh fabrics, Mersilene (Ethicon), Marlex (Davol), and Teflon (USCI), were used, and the tests reveal that they differ from one another chemically as well as configurationally. The experiment included an identification of the structure of the yarn and fabrics; a measurement of the porosity, pore size and shape; and a determination of tensile and bursting strength, flexural rigidity, and wrinkle recovery. A wide variation in structure and performance was observed among the three mesh fabrics. Mersilene mesh fabrics have the highest relative porosity, while Marlex and Teflon meshes have an equivalent, but lower value. Marlex meshes have the highest tensile and bursting strength followed by Teflon and Mersilene meshes. All three meshes have one common strength characteristic--a distinctive difference in tensile strength between the wale and course directions. Marlex mesh fabrics exhibit an immense flexural rigidity and poor wrinkle recovery, due mainly to the monofilament structure of the yarn. Mersilene and Teflon mesh fabrics have similar but considerably lower, flexural rigidity than Marlex. Thus, it is evident that the chemical nature of the constituent fibers, as well as the yarn and fabric structure, have a great effect on the performance of the resulting mesh fabrics. The availability of this characterization data can serve as the basis for a surgeon's selection of the most appropriate commercial surgical mesh fabric for each case, as well as to provide a foundation for the subsequent comparison of their in vivo performance.

Porosity of surgical mesh fabrics: new technology.

A new method using an image processing system developed in our laboratories is used to measure the pore size in Mersilene, Marlex, and Teflon surgical meshes. All three meshes appear to have sufficiently large pores and should facilitate tissue growth/attachment. Results obtained in this study are compared to results of an earlier paper.

Induction of leukocyte activation by meshes surgically implanted in the peritoneal cavity.

The search for surgical prosthetics that do not act to promote infection has been frustrating. However, recent experience with the implantation of polyglycolic acid mesh (PGA) used as an intestinal sling has been associated with a lack of pelvic infections. To examine the basis for these observations, 1 x 1-cm pieces of biomaterials were sewn onto the peritoneal cavity of rats. The biomaterials examined included PGA mesh, a composite mesh composed of a permanent nonabsorbable Novafil inner layer coated with a PGA outer layer, polyvinyl alcohol sponge, and silicon elastomer. Biomaterials were removed at postoperative days 1, 2, 8, and 14, and examined for bacteriostatic and bactericidal activity by standard techniques. Mesh adherent leukocytes were evaluated for their ability to oxidize dichlorofluorescein diacetate (DCFH-DA), which is fluorescent in the presence of intracellular hydrogen peroxide produced by both polymorphonuclear cells and monocytes. PGA and the composite mesh had no intrinsic bacteriostatic or bactericidal activity. However, adherent leukocytes were induced to oxidize DCFH at levels 10-fold and 5-fold, respectively, by postoperative day 14, compared with earlier time points and other biomaterials. The ability of these PGA meshes to stimulate respiratory bursts by peritoneal cells may partly be responsible for the lack of infections associated with their use.

[Experience with a surgical mesh covering a hepatectomy incision].

A polyglycolic acid net (Vicryl) has been applied against the hepatectomy section of 27 patients (14% of all our liver resections) to complete its hemostasis. The indications for the use of this net were: the persistence of blood oozing and/or the necessity to shorten the operation. In one patient suffering from severe coagulopathy, active bleeding continued until the patient died; another patient bled until his blood dyscrasia was corrected. One case of abscess was encountered, and treated through a percutaneous approach. Although the achievement of perfect hemostasis is usual in surgical exeresis of the liver, a minority of patients can present with resistant bleeding of the resection slice, for which packing with a net may prove to be useful.

[Inguinal herniorrhaphies by the pre-peritoneal method using surgical mesh].

During a period of 5 years, 314 patients with 427 inguinal hernias were operated. 80 males with bilateral inguinal hernia recurrent, or not, were operated with an insertion of a Crinoplaque by a pre-peritoneal approach. The operative time was 65 +/- 26 minutes. 10 patients (12.5%) had by the same incision a concomitant pelvic procedure (9 varicoceles, 1 benign prostatic hypertrophy). 4 patients (5%) developed minor parietal complications. After 1 to 4 years of follow-up, 1 patient (1,25%) showed one side recurrence, in the beginning of our experience. In conclusion, we consider the pre-peritoneal Crinoplaque insertion as a treatment of choice for bilateral recurrent, or not, inguinal hernia for its simplicity and its lower complication rate.

Renorrhaphy using knitted polyglycolic acid mesh.

Surgical techniques for treatment of penetrating trauma to the kidney have ranged from simple drainage to nephrectomy, depending on the severity of the injury. Based upon successful experience in the surgical management of splenic injuries using knitted polyglycolic acid mesh, we report a case in which absorbable mesh was used to repair a laceration of the kidney.

Technical note: development of a duodenal cannula for sheep.

A single T-shaped duodenal cannula of silicone rubber with a gutter-type small inner flange was developed for sheep. The barrel of the cannula was 24 mm long with an internal diameter of 12 mm. A polyester surgical mesh (100 mm x 100 mm) was connected to the barrel of the cannula as an anchor. Fibrous tissues grew on the polyester mesh anchor and adhered firmly to the serosa of the intestine, thus leaving no gap and, hence, preventing any leakage of intestinal contents from the side of the fistula. The small (24 mm in diameter) and thin (3 mm in thickness) outer flange of the cannula became buried in the wool and prevented any mechanical disturbance of the cannula by the activity of the animal. The elasticity of the silicone rubber prevented distortion of the duodenum around the barrel of the cannula. No erosion of the tissue between the inner flange of the cannula and the mesh was seen in postmortem observations.

[Securing colon anastomoses by surrounding it with a polyglycolic acid filament net. An animal experiment study].

Resorbable polyglycolic-acid (PGA)-nets are used successfully for the treatment of traumatic ruptures of parenchymous organs. This experimental study was carried out to investigate whether PGA-nets can also re-enforce jeopardized colon anastomoses. In 75 Wistar rats the transverse colon was transsected and reanastomosed. Animals were divided into 2 groups: in one group the anastomosis was applied sufficiently, in the other group the anastomosis was applied potentially insufficient. Out of each group a PGA-net was placed around the anastomosis in one half of the animals. The results demonstrated that delayed healing of the anastomoses as well as spontaneous suture line disruptions followed by peritonitis only occurred in those animals in which a PGA-net had been used. The evaluation of the bursting strength could confirm this finding of delayed consolidation. The bursting pressure therefore was significantly decreased in all animals in which a PGA-net had been applied, compared to the control group operated without PGA-net application. We therefore conclude that PGA-net application in colon anastomoses inhibits the consolidation of the suture line, probably because of a lack of contact to the peritoneal and omental tissue.

Sutureless laparoscopic rectopexy for procidentia. Technique and implications.

Procedures for treating rectal prolapse may constitute some of the best applications for colorectal laparoscopic techniques. Although the condition is benign, rectal prolapse is often debilitating and frequently progressive in terms of functional limitations. Moreover, many patients are elderly, medically unfit, or both. A technique that afforded relief of prolapse and of incontinence by laparoscopic rectal sacropexy, performed without sutures, using a newly designed laparoscopic sacral tacker and laparoscopic staples, is described. Indications, contraindications, technical details, and surgical implications are discussed. Laparoscopic pelvic suspension procedures are presented as realistic and appropriate objectives for colon and rectal surgeons.

Exploding the myths of hernia repair.

Sacred prinicples guiding surgical repair of groin hernias have remained basically unaltered since their inception. This may explain the failure of results to improve significantly over the years. Ten hallowed concepts have been critically analyzed in the light of modern technology and contemporary experience. Although challenging established surgical traditions invariably invites debate, it is essential to scientific progress.

Functional alveolar reconstruction in a patient with total mandibular replacement.

Alveolar reconstruction in a case of total mandibular replacement is presented. The placement of hydroxylapatite bone substitute and the staple bone plate into a previously grafted area demonstrates that the properties of transplanted bone are similar to natural bone. Furthermore, the safety and effectiveness of the utilization of these biomaterials in areas of previous osseous reconstruction is documented. An awareness of biologic tissue response may have also contributed to successful functional restoration. In addition, a major question about the functions of the muscles of mastication arises.
