[Experimental study of the suture of the intraocular lens sutured to the ciliary sulcus. Needle passage and distance from the limbus].

OBJECTIVE: To discover which technique is best to scleral suture fixation of the lens in the ciliary sulcus, based on two needle direction options: passing the needle from the outer part of the eyeball inwards or from the inner part outwards and to know at what distance the needle must be passed from the sclerocorneal limbus. MATERIAL AND METHODS: We used 40 cadaver eyes conserved in 10% formaldehyde. The needle was passed from the interior to the exterior of the eye, observing whether if it had crossed through the ciliary sulcus and the distance of the needle from the limbus. Stitches were also made, going from the exterior to the interior of the eyeball at a known distance from the limbus, either parallel to the iris or perpendicular to the sclera. RESULTS: When the needle was passed from the interior toward the exterior of the eye, it passed through the ciliary sulcus, exiting the eye at 1.50+/-0.16 mm from the limbus, in 80% of the cases. When the needle was passed from the exterior toward the interior of the globe perpendicularly to the sclera only 32.5% passed through the sulcus and when it was parallel to the iris only, only 40%. There is greater statistical probability that the needle will pass through the sulcus from the interior of the eyeball, exiting the limbus at approximately 1.5 mm. CONCLUSION: Since it is necessary to pass the suture through the sulcus in order to be able to place the lens haptics in the ciliary sulcus when suturing a posterior chamber lens to the sclera, it is best to pass the needle from the interior to the exterior of the eyeball and for the needle to exit at approximately 1.5 mm from the limbus.

Absorbable subcuticular sutures. How to avoid the childhood ordeal of suture removal.

Suture removal is psychologically traumatic to a child, and in the majority of relatively minor elective operations is a totally unnecessary procedure. Skin repair with subcuticular sutures of absorbable polyglycolic acid (Dexon) is advocated. Techniques of suturing are described. Advantages, potential disadvantages and contraindications are discussed.

[Laparoscopic suture or open suture in perforated duodenal ulcer].

Between Nov. 1994-Jan. 2001 we performed laparoscopic suture with omentoplasty of perforated duodenal ulcer (PDU) in 51 patients out of 56 it was intended (this constituted the laparoscopic group--LG). The selection criteria were young patients, age < 40 years, no associated diseases, onset of the operation under 12 hours from the occurrence of the perforation, absence of clear ulcer history. In the same period, we performed an open suture based on the same criteria in 105 patients (open group--OP). The results showed a difference between needed analgesia (2.8 days for LG vs. 5.2 days for OG) and a hospital stay of 6.1 days in LG vs. 7.7 days in OG. The incidence of postoperative complications was 5.88% in the LG and 7.61% in the OG with 1.96% and respective 1.90% reoperation rate. In conclusion laparoscopic suture of PDU with associated postoperative modern therapy of ulcer disease could be the treatment of choice in young patients.

A single continuous suture as a possible alternative to the interrupted suture for tubal anastomosis.

A simple alternative for microsurgical anastomosis of the fallopian tube is presented. The anastomosis is composed of a single continuous suture (8-0 nylon) extending through the serosa and muscularis, avoiding the mucosa. Experimentally this technique was performed on the uterine horns of 30 female rats and compared with the conventional interrupted suture technique on 30 additional female rats. Patency was established histologically in 100% of operated horns in both groups, with an average nidation index of 0.7 in the study group as compared with 0.6 in the conventional technique group. The results indicate that this simple method of anastomosis, which reduces operative time significantly, does not affect patency or nidation index in this model as compared with the conventional interrupted suture technique. It may, therefore, be a suitable procedure for anastomosis of equal-sized segments of the fallopian tubes, especially in cases of reversal of sterilization.

[Healing of ruptures of the anterior cruciate ligament treated with simple sutures. Possibilities, usefulness, clinical evaluation. Apropos of a series of 51 anterior cruciate ligament sutures using barbed wire with macroscopic verification of the healing].

Fifty-one ruptures of the anterior cruciate ligament were treated by early suture using barbed wires followed by plaster cast for 6 weeks. The state of healing was assessed by a second look during arthrotomy to remove the wire after an average of 6 months. In addition, 45 knees have been examined more than 20 months after the initial repair. Three out of 4 ligaments were found to be healed, but only one out of 3 had adequate tension and was correctly sited. The rate of satisfactory healing was high in cases of clear-cut rupture and when the pre-operative laxity was moderate. Associated lesions of the collateral ligaments healed satisfactorily thanks to the period of 6 weeks treatment in the plaster cast. The cases in which the cruciate ligaments had healed demonstrate subjective and objective stability better than others, even when the ligament had been found to be loose or incorrectly re-implanted and were superior from the functional point of view. There was no parallel between the true state of healing of the ligament and the clinical tests of stability. It is concluded that early suture of the cruciate ligament is worthwhile in cases of clear-cut rupture. In cases of attenuation or when there are severe lesions of the collateral ligaments, suture of the cruciate ligaments should be reinforced by carbon fibres. This management is valuable in active people or amateur sportsmen in whom rehabilitation is somewhat slow. In professional athletes peripheral ligamentoplasties lead to earlier resumption of sporting activities. In older patients, plaster cast immobilisation is sufficient to produce satisfactory results.

Frequency of induced astigmatism following phacoemulsification with suturing versus without suturing.

BACKGROUND AND OBJECTIVES: To compare the postoperative astigmatism between sutured wounds and nonsutured wounds after cataract surgery with a 3.2-mm scleral tunnel incision. PATIENTS AND METHODS: One hundred ten eyes of 110 patients were studied. Eyes with cataracts were randomly assigned to either the sutured or the unsutured procedure. Identical surgical methods were used in every case except for wound closure technique. Data on uncorrected visual acuity and induced astigmatism were analyzed for 6 months after the surgery. RESULTS: Both groups displayed similar uncorrected visual acuity. Mean induced corneal astigmatism was "against-the-rule" with both techniques, and it remained stable during the study. No significant differences were found between the two groups (P > .1). CONCLUSION: This study has shown that the differences in surgically induced astigmatisms of sutured wounds and nonsutured wounds after cataract surgery were not statistically significant when a 3.2-mm self-sealing incision was used.

[Dynamics of thickness and width of the scar after suturing the wound of the stomach wall with different methods of external protection of the penetrating suture in an experiment].

The results of morphometric study of the effect of one-row penetrating suture external protection with musculoserous sutures, flap of the great omentum on vascular peduncle, surgical glue "Sulfacrilat" and collagenic explant "Sanguicol" in necrotic gastric wounds of 79 rabbits were represented. Single orientation of dynamics of the scar width and thickness under protection with the great omentum flap, surgical glue and collagenic explant and peculiarities of their dynamics in peritonization with musculoserous sutures were demonstrated. In submucosal coat the scar width was shown to exceed those in muscular one during initial period of the intervention and heterochronous convergention of the scar width in the gastric wall layers dependent on the method of external protection was discovered as well.

Strength of the suture in the epitenon and within the tendon fibres: development of stronger peripheral suture technique.

In tendon repair, the peripheral stitches are usually placed in the epitenon, but it has not yet been defined whether the grasping strength of the sutures in the epitenon and within the tendon fibres are different. The first stage of this work investigated this difference and found that peripheral stitches within cadaveric tendon fibres were 83% stronger than those in the epitenon layer. A new peripheral stitch, based on this finding, has been designed. Mechanical tests of a range of peripheral suture types in vitro found that the new technique gave a resistance to gap formation twice that of the peripheral stitches commonly in use at present and a rupture strength more than three times, while still avoiding eversion problems.

Study of the efficacy of Coated VICRYL Plus Antibacterial suture (coated Polyglactin 910 suture with Triclosan) in two animal models of general surgery.

OBJECTIVES: To evaluate the efficacy in vitro and in vivo of a new antibacterial suture (PGAB) compared with a traditional braided suture (PG). Our primary goals were to study microbiological effectiveness and impact on wound healing of PGAB vs PG. Secondary goal was to analyze influence on inflammatory response. METHODS: In vitro study: clinical samples of Staphylococcus epidermidis, Staphylococcus aureus, S. hominis, Staphylococcus haemolyticus, Staphylococcus auricularis, Enterococcus faecalis, Corynebacterium spp. and Escherichia coli were studied. We also implanted a flat mesh in 10 minipigs, four incisions each (two PG and two PGAB) two contaminated with S. epidermidis and two not contaminated. Finally, we performed four colic anastomosis in each of 10 minipigs, two contaminated with E. coli and two not contaminated (two PG and two PGAB). We studied the inflammatory and wound healing processes in both models. RESULTS: We observed a bactericidal efficacy of PGAB against grampositive, and bacteriostatic effect against E. coli. Mesh study: recovered CFU were lower in the group PGAB vs PG. In the group PGAB, inflammatory mediators' concentrations were lower. In the group PGAB, concentrations of wound healing mediators were normal. Colic anastomosis: recovered CFU were lower in the group PGAB vs the group PG. In the group PGAB we observed a reduction of inflammatory mediators. In the group PGAB we observed normalized concentrations of wound healing mediators. CONCLUSIONS: This study demonstrates microbiological efficacy of PGAB, that normalizes wound healing process, and an anti-inflammatory effect.

[Sutures and suture technics. Current trends and our method in oral surgery].

Suture techniques are a fundamental aspect of surgical practice in terms of the successful outcome of the operation. Even in dentistry it is important to have a clear idea of the method and the type of thread used. This paper lists the types of suture threads most commonly available today, the main techniques used and, on the basis of the authors' personal experience, explains a method used for oral surgery.

[Experiences with a resorbable suture (PDS) in tendon sutures].

67 tendon sutures were performed on 29 patients using polydioxanon (PDS), a synthetic absorbable suture material. The results after a mean survey period of twelve months are documented; there were no ruptures and fistula, only two infections and in four cases the need for tenolysis. In the reconstruction of isolated flexor tendon injuries 89% excellent results were found. The satisfactory and bad results in reconstructing flexor and extensor tendon injuries accompanied by complex hand injuries are analyzed and discussed.

[Development of the mechanical suture and comparison with the manual suture in surgery].

Mechanical sutures in surgery were first used in 1908 by Hültl. Since then they have found a large field of application in thoracic and abdominal surgery because of their ease in handling and consequent reduction of duration of operation, as well as reduction of contamination from hollow organs. Safety, diminished tissue trauma and early function of anastomotic continuity are other advantages that recommend the use of staplers over hand sutures.

[Percutaneous suture of femoral artery access sites after diagnostic heart catheterization and or coronary intervention. Safety and effectiveness of a new arterial suture technic].

UNLABELLED: The safety and efficacy of a suture-based closure device designed to achieve hemostasis at the femoral access site post catheterization procedures was compared to manual compression in a 600 patients randomized trial (data available for 590 patients). The patients were randomized to percutaneous vascular surgery (PVS) or manual compression after diagnostic (401 patients) and interventional (189 patients) procedures. Two types of PVS devices were used delivering 1 or 2 sutures at the arterial access site. The overall results as well as the results by procedure type demonstrated a significant reduction in time of hemostasis (7.8 +/- 4.8 min vs 19.6 +/- 13.2 min, p < 0.01) and time to ambulation (4.5 +/- 6.5 hours vs 17.8 +/- 5.0 hours, p < 0.01) with the use of the PVS device. The safety results showed no significant differences in the incidence of vascular complications (5.7% for PVS vs 11.3% for compression) in the overall population or in the interventional patients subset (8.4% for PVS vs 9.6% for compression). However, the PVS device demonstrated a significant reduction in the incidence of vascular complications post diagnostic catheterization procedures (4.4 for PVS vs 12.1% for compression, p < 0.05). The incidence of vascular complications and the time of hemostasis was similar in an American multicenter study (STAND II). CONCLUSION: Percutaneous vascular surgery is a safe and effective method to achieve hemostasis post catheterization procedure providing faster hemostasis and ambulation without increasing the rate of complication.

[Is the stapled suture in visceral surgery still justified? A prospective controlled, randomized study of cost effectiveness of manual and stapler suture].

Hospitals are facing increasing economic pressure. It therefore seems necessary to evaluate the efficiency and effectiveness of medical or surgical interventions. In this study 324 anastomoses (167 stapled and 157 hand-sewn) were performed after randomization during 200 elective operations [20.5% gastrectomies, 14% gastric resections (Billroth II), 15% Whipple's procedures, 4% segmental colonic resections, 18% right-sided hemicolectomies, 4% left-sided hemicolectomies, 22% sigmoid- or anterior rectal resections, 2.5% total colectomies with pouch-anal anastomoses] in 200 patients. Postoperative motility (time to full oral diet, time with naso-gastric tube) and hospitalization were comparable in both groups. Anastomotic insufficiency was observed in 2.1% of all patients, five after stapled and two after hand-sewn anastomoses. Hospital mortality was 1.5%. All stapled anastomoses were performed significantly (P < 0.001) faster. However, the cost of material for these anastomoses was significantly (P < 0.001) higher, resulting in significantly higher total costs for reconstruction. The time saving for the reconstruction did not influence the total operative time (except for stapled gastrectomy). Therefore, all operations with stapled reconstruction were more expensive than those with sutured reconstruction. The difference was significant for the gastrectomy (P < 0.01), colonic resection (P < 0.01) and sigmoid and rectal resection (P < 0.001) groups. Stapled and sutured anastomoses are equally effective. Stapled anastomoses are not efficient, however, and should be reserved for individual indications.

A novel dysmorphic syndrome with open calvarial sutures and sutural cataracts maps to chromosome 14q13-q21.

We describe a new dysmorphic syndrome in an inbred Saudi Arabian family with 21 members. Five males and one female have similar craniofacial features including wide open calvarial sutures with large and late-closing anterior fontanels, frontal bossing, hyperpigmentation with capillary hemangioma of the forehead, significant hypertelorism, and a broad and prominent nose. In addition, these individuals have Y-shaped sutural cataracts diagnosed by 1-2 years of age. No chromosomal or biochemical abnormalities were identified. A genome-wide scan was performed, and two-point LOD score analysis, assuming autosomal recessive inheritance, detected linkage to chromosome 14q13-q21. The highest LOD scores were obtained for marker GATA136A04 (LOD=4.58 at theta=0.00) and for the adjacent telomeric marker D14S1048 (LOD=4.32 at theta=0.00). Multipoint linkage analysis resulted in a maximum LOD score of 5.44 between markers D14S1048 and GATA136A04. Model independent analysis by SIBPAL confirmed linkage to the same chromosomal region. Haplotype analysis indicated that all affected individuals were homozygous for the interval on chromosome 14q13-q21 with two recombinants for D14S1014 (centromeric) and one recombinant for D14S301 (telomeric). These recombinations limit the disease locus to a region of approximately 7.26 Mb. Candidate genes localized to this region were identified, and analysis of PAX9 did not identify mutations in these patients. The unique clinical phenotype and the mapping data suggest that this family represents a novel autosomal recessive syndrome.
