The triangular vaginal patch sling for stress urinary incontinence and hypermobile urethra

OBJECTIVE: We describe an alternative sling procedure that permits concomitant correction of urethral hypermobility and urinary incontinence through a single surgical exposure. STUDY DESIGN: Fifteen women with severe urinary stress incontinence and urethral hypermobility underwent a sling procedure by creation of a simple triangular patch from the anterior vaginal wall. RESULTS: The mean operative time for the vaginal sling procedure was 38 minutes (range 29 to 65 minutes) in addition to other operations. The mean postoperative hospital stay was 7.7 days (range 5 to 13 days) and all patients were routinely discharged with an indwelling Foley catheter. Spontaneous micturition occurred in 12 patients after a mean period of 25 days (range 13 to 36 days). In three cases long-term catheterization was necessary. By subjective and objective evaluations, all the patients were cured of their stress incontinence. CONCLUSION: The triangular vaginal patch with the single sutures on each side provides an alternative approach for bladder neck stabilization that may permit a more anatomic suspension of a hypermobile urethra.(Am J Obstet Gynecol 1997;177:31)     

Repair of anterior mitral leaflet prolapse using artificial Gore-Tex loops in preoperatively echo-determined length

Background Chordae reconstruction is one of the key points in repair of mitral valve prolapse,especially for anterior leaflets.Here we introduce our experiences of using echo-determined normal chordael length to make the loops preoperatively and rebuild the elongated / ruptured chordae intraoperatively.Materials and method From June 2011 to February 2012,19 consecutive cases with mitral anterior leaflet prolapse underwent valve repair procedures.Echocardiography was used to determine the length of normal chordae that the prolapsed leaflets should have for normal coaptation.The artificial chordae was fabricated in loops according to echo-determined length.Results All patients survived the operations.2.8 preoperatively prepared loops were used per patient to restore the anterior leaflets,as well as posterior leaflets.Artificial mitral valve rings were applied to 18 patients for mitral annuloplasty.16 patients were underwent different concomitant operations.Echocardiographic results at discharge showed that grade of mitral regurgitation,left ventricular end-diastolic,end-systolic dimension decreased definitely,respectively from 3.26 ± 1.10,53.79 ± 15.03 mm,33.00 ± 12.05 mm preoperatively to 0.47 ± 0.61(P < 0.01),44.74 ± 10.28 mm(P < 0.01),30.16 ± 10.58 mm(P < 0.05)postoperatively.All patients improved clinically and NYHA functional class decreased significantly from 2.17 ± 0.81 to 1.12 ± 0.33.Conclusion Reconstruction of prolapsed anterior leaflet chordae with artificial loops in preoperatively echo-determined length is safe and effective,and initial clinical outcome is satisfactory.     

Seroma after laparoscopic repair of hernia with PTFE patch: is it really a complication?

We evaluated the true incidence of seroma formation after laparoscopic repair of incisional hernia with polytetrafluoroethylene (PTFE) patch. In a prospective study, 20 patients who underwent laparoscopic repair of incisional hernia with PTFE were evaluated clinically and with ultrasound examination for seroma formation up to the 90th postoperative day. Seroma was diagnosed clinically in only 35% of cases, while ultrasound examination revealed the presence of seroma in 100% of patients. Ultrasound examination is a reliable tool for diagnosis of early or delayed postoperative seroma formation following laparoscopic repair of incisional hernia with Gore-Tex Dualmesh.

Sciatic hernias: choice of optimal prosthetic repair material in preventing long-term morbidity

Summary The case of a 77-year old female who presented with a buttock lump is reported. A sciatic hernia was diagnosed clinically. A transabdominal approach revealed this to be a greater sciatic hernia, which was repaired using an onlay of Gore-Tex dual mesh. Sciatic hernias are extremely rare, and it is the authors' opinion that use of such an inert material within the pelvis may prevent morbidity due to adhesions. The rationale for using this material in preference to other commonly used materials is discussed.

Angina pectoris caused by subclavian coronary steal

A 79-year-old white woman underwent coronary bypass graft surgery using a left internal mammary artery graft. The patient represented with chest pains 4 months later. A total occlusion of the left subclavian artery was documented with a coronary subclavian steal. The patient was treated with an axillo-axillary Gore-Tex graft. Pathophysiology and therapeutic options of the coronary subclavian steal are discussed.© 1993 Wlley-Liss, Inc     

Thyroplasty type I without arytenoid adduction in patients with unilateral laryngeal nerve paralysis: the montgomery implant versus the Gore-Tex implant

Objective The current series was designed to compare the results achieved with the Montgomery and Gore-Tex implants in thyroplasty type I without arytenoid adduction in patients with unilateral laryngeal nerve paralysis.

Material and Methods An inception cohort of 57 French language speakers with unilateral laryngeal nerve paralysis were managed with thyroplasty type I using Gore-Tex (Group GT; n=24) or Montgomery (Group M; n=33) implants. The two groups had similar patient characteristics. Morbidity, phonatory results according to self assessment by the patient and selected speech and voice parameters (fundamental frequency, jitter, shimmer, noise:harmonic ratio, phonation time, phrase grouping and speech rate) were analyzed 1 month postoperatively in both groups.

Results Dyspnea, as noted in three patients, was the only immediate complication. Late complications included persistent inflammation of the vocal cord after insertion of a Gore-Tex implant, endolaryngeal extrusion of the Gore-Tex implant and dislodgment of the Montgomery implant in one patient each. Postoperatively, all patients reported improvements in speech and voice. Secondary degradation of speech and voice was noted in one patient in each group. Comparison of selected speech and voice parameters at 1 month postoperatively showed (i) a statistically significant (p<0.01) decrease in the jitter, shimmer and noise:harmonic ratio values and (ii) a statistically significant (p<0.01) increase in the speech rate values in Group M compared to Group GT patients. Also, a trend (0.05<p<0.1) was noted towards an increase in the phrase grouping values in Group M compared to Group GT patients.

Conclusions Although limitations exist in the interpretation of the reported data, our results suggest that in patients with unilateral laryngeal nerve paralysis managed with a thyroplasty type I technique without arytenoid adduction, the use of a Montgomery compared to a Gore-Tex implant does not influence the success of the procedure according to the patient's self evaluation or the morbidity but does lead to a significant improvement in the values of selected speech and voice parameters.     

Congenital diaphragmatic hernia: onset of respiratory distress and size of the defect

The purpose of this study was to evaluate the outcome in neonates with congenital diaphragmatic hernia (CDH) either presenting within the first 24 h of life or diagnosed prenatally. The study was particularly focused on the time of onset of respiratory distress and on the use of the Gore-Tex (GT) patch for diaphragmatic reconstruction. Records of 104 neonates with CDH were retrospectively reviewed. The data were analyzed by ANOVA, Kruskal–Wallis test or χ ² test as appropriate. The result showed that the overall survival rate was 73.1% (76/104). Survival of operated neonates was 91.6% (76/83). Postnatally diagnosed neonates with the onset of respiratory distress within the first minute of life survived in 67%, with the onset between 2 and 10 min survived in 89%, whilst neonates with the onset of respiratory distress after l0 min survived in 100% (P = 0.007). Birth weight, gestational age, time of onset of respiratory distress and Apgar score significantly differed between survivors and nonsurvivors. Primary closure of the diaphragmatic defect was performed in 62 patients while the GT patch was used in 21 patients. The survival of patients with a large defect treated with a GT patch was lower (76.2 vs. 96.8%, P = 0.003). There was only one case of recurrence in our series with the GT patch. Survival depends on the time of onset of respiratory distress and size of the defect, both of which correlate with the degree of pulmonary hypoplasia. The term high-risk CDH is appropriate only for children with respiratory distress within the first 10 min of life and those diagnosed prenatally. The GT patch is a suitable material for the diaphragmatic reconstruction; we suppose that the recurrence is caused by incorrect attachment of the patch to the thoracic wall.
