In recent years, there is a growing evidence that using 5-aminolevulinic acid (5-ALA)-guided resection of a cerebral glioblastoma, associated with chemoradiotherapy determine a prolonged survival of these patients, even though this period do not exceed 15 months. 5-ALA is a natural biochemical precursor of heme that is metabolized to fluorescent porphyrins, particularly protoporphyrin IX (PPIX) and no foreign reaction were noted until now. However, foreign body reaction developing in neurosurgery is documented in a few number of cases to suture material, surgical hemostatic material, or surgical glove starch, but up to now we could not find any article about granulomatous inflammation to polyglycolic acid (PGA) suture after brain tumor resection...

INTRODUCTION: Though surgical drainage is used as a safety measure, it's not without complications. Migration of various drains has been described, but very little literature refers to the migration of peritoneal drain. PRESENTATION OF CASE: A 55-year male underwent anterior Gastro-Jejunostomy for inoperable metastatic carcinoma of the Gastric Pylorus. We found the peritoneal drain missing on the third post-operative day. On further evaluation, we found it to have migrated into the peritoneal cavity...

Today's sutures are the result of a 4000-year innovation process with regard to their materials and manufacturing techniques, yet little has been done to enhance the therapeutic value of the suture itself. In this review, we explore the historical development, regulatory database and clinical literature of sutures to gain a fuller picture of suture advances to date. First, we examine historical shifts in suture manufacturing companies and review suture regulatory databases to understand the forces driving suture development...

Sutures penetrate tissues to close wounds. This process leads to inflammatory responses, prolongs healing time, and increases operation complexity. It becomes even worse when sutures are applied to stress-sensitive and fragile tissues. By bonding tissues via forming covalent bonds, some medical adhesives are not convenient to be used by surgeons and have side effects to the tissues. Here egg albumen adhesive (EAA) is reported with ultrahigh adhesive strength to bond various types of materials and can be easily used without any chemical and physical modifications...

INTRODUCTION: There continues to be debate regarding the best surgical technique for the treatment of paraesophageal hernias. While laparoscopic and robotic approaches are widely employed around the world, the benefits of mesh use to reinforce hiatal closure are still not well established. The goal of this manuscript is to describe the currently available results with biologic and bioabsorbable meshes for treatment of paraesophageal hernias, particularly with reference to the rate of recurrence...

Nowadays there is a wide variety of surgical sutures available in the market. Surgical sutures have different sizes, structures, materials and coatings, whereas they are being used for various surgeries. The frictional performances of surgical sutures have been found to play a vital role in their functionality. The high friction force of surgical sutures in the suturing process may cause inflammation and pain to the person, leading to a longer recovery time, and the second trauma of soft or fragile tissue. Thus, the investigation into the frictional performance of surgical suture is essential...

This technique is used when a single dental implant is placed. A stent made of autopolymerized acrylic resin was used to transfer the implant position to the laboratory. Once the implant position was transferred, the stone cast was scanned, and a computer-aided design and computer-aided manufacturing (CAD-CAM) interim implant-supported crown was milled from a poly(methyl methacrylate) (PMMA) block. A titanium insert, in contact with the implant platform and not the PMMA material, was used to support the crown...

INTRODUCTION: Craniosynostosis is a rare condition and requires a personalised surgical approach, which is why we consider the use of 3D printed models beneficial in the surgical planning of this procedure. MATERIAL AND METHODS: Acrylonitrile butadiene styrene plastic skull models were designed and printed from CT images of patients between 3 and 6 months of age with craniosynostosis of different sutures. The models were used to simulate surgical procedures. RESULTS: Four models of four patients with craniosynostosis were produced: two with closure of the metopic suture and two with sagittal suture closure...

Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) has an effective role in both diagnosis and management of patients with lung cancer. There are many reasons could cause false positivity on PET/CT.A 60-year-old man was admitted a mass on thorax CT and diagnosed as squamous cell carcinoma. Lobectomy with lymph node dissection was performed after evaluation of distant metastases. There were pathological lymph nodes detected on PET/CT at six month following period. Endobronchial ultrasonography guided transbronchial needle aspiration was performed for differantial diagnosis...

OBJECTIVE: To investigate the anti-slip strength of closing systems employing sutures terminated with a Hem-o-Lok®/Lapra-Ty® clip combination to determine which sutures perform best for this application. Partial nephrectomy (PN) is the reference standard for treatment of small renal masses. The main disadvantage of PN is the risk of technical complications, including renorrhaphy site bleeding and urine leak. MATERIALS AND METHODS: A materials testing system produced a constant velocity pull on the free end of an anchored suture...

PURPOSE: Anastomotic or "stitch hole" bleeding is common during vascular surgery with synthetic material such as Dacron or polytetrafluoroethylene (PTFE). Hemostatic adjuncts such as fibrin sealant (FS) may reduce blood loss and operating time in such circumstances. We evaluated the safety and the hemostatic effectiveness of a ready-to-use human plasma-derived FS in vascular surgery. METHODS: Patients with mild / moderate suture line bleeding during elective, open, vascular surgery using synthetic grafts or patches were studied...

Conventional surgical techniques to seal and repair defects in highly stressed elastic tissues are insufficient. Therefore, this study aimed to engineer an inexpensive, highly adhesive, biocompatible, and biodegradable sealant based on a modified and naturally derived biopolymer, gelatin methacryloyl (GelMA). We tuned the degree of gelatin modification, prepolymer concentration, photoinitiator concentration, and crosslinking conditions to optimize the physical properties and adhesion of the photocrosslinked GelMA sealants...

BACKGROUND: There is no international consensus regarding the optimum management of infected aortae (mycotic aneurysms, infected aortic grafts). Neoaortoiliac reconstruction has advantages over extra-anatomical bypass grafting; however, the use of autologous vein is associated with venous hypertension and compartment syndrome, alternatively cadaveric homografts are associated with high rates of perianastomotic hemorrhage, limb occlusion, and pseudoaneurysm. Arterial repair using xenoprosthetic patches is associated with lower infection rates compared to the use of prosthetic material...

The present study compares a knotless, barbed, absorbable suture material against a conventional monofilament absorbable suture material in oral mucosal wound closure. The parameters measured include time of closure and differences in healing at 2 and 4 weeks postoperatively. A prospective study comparing a knotless, barbed suture system with conventional absorbable sutures was undertaken in 19 cats. Nineteen cats had full mouth extractions performed. Following the extraction procedures, the incisions in the arcades (maxillary and mandibular) were apposed with the barbed, knotless suture system in a continuous pattern on one side and with a conventional smooth suture in an interrupted pattern on the other...

INTRODUCTION AND HYPOTHESIS: Surgeons use a variety of sutures and knot-tying methods during pelvic reconstructive procedures. We hypothesized that knot-strength integrity will be similar with regards to type of knot, type of suture, and the knot-tying process. METHODS: Using six different suture materials, flat square knots and slip knots were tied robotically and by hand by two surgeons. Knot integrity was evaluated using an Instron 5544 machine. We measured force and elongation at suture failure or knot slippage (whichever came first) as well as force at 3-mm displacement...
