TVT and TVT-Obturator: comparison of two operative procedures

AIM: To compare two anti-incontinence operations: the tension-free vaginal tape (TVT) and the TVT-Obturator for the first two 75-patient groups. METHODS: One surgeon operated on two patient groups with urodynamically proven urinary stress incontinence. The first 75-patient group in 1998 included the first TVT procedures performed according to Ulmsten [Ulmsten U, Henriksson L, Johnson P, Varhos G. An ambulatory surgical procedure under local anesthesia for treatment of female urinary incontinence. Int Urogynecol J 1996;7:81-6]. Follow-up lasted for 5-6 years. The second 75-patient group in 2004 included the first TVT-Obturator operations performed according to [De Leval J. Novel surgical technique for the treatment of female stress urinary incontinence: transobturator vaginal tape inside-out. Eur. Urol. 2003;44:724-30]. Follow-up lasted for 6-13 months. RESULTS: The two patient groups were similar from the demographic and therapeutic points of view. The TVT-Obturator procedure required neither bladder catheterization nor intra-operative diagnostic cystoscopy. TVT-related bladder penetration (8.0%), post-operative voiding difficulties (5.0%), intra-operative bleeding (4.0%), post-operative field infection (2.7%), and post-operative pelvic floor relaxation (1.3%) were not noted with the TVT-Obturator. The early therapeutic failure rates were 2.7% for the TVT and 1.3% for the TVT-Obturator, and neither bowel nor urethral injuries were recorded. CONCLUSIONS: The surgeons' learning curves of these two minimally invasive surgical procedures for the treatment of female urinary stress incontinence are comparable. The safety and cost-effectiveness of the TVT are well-established. The TVT-Obturator, a novel mid-urethral sling, was designed to overcome some of the TVT-related operative complications. The TVT-Obturator patients seem to have less intra-operative and post-operative surgical complications than the TVT patients. However, long-term comparative data collection is required prior to drawing solid conclusions concerning the superiority of one of these two operative techniques.     

Recurrence of dysplasia after loop electrosurgical excision procedures with long-term follow-up

OBJECTIVE: The aim of this study was to determine the rates of recurrent dysplasia with longer follow-up durations and to determine whether margin status and other variables were associated with recurrence. STUDY DESIGN: A retrospective chart review was performed for all women who underwent a loop electrosurgical excision procedure at Wilford Hall Medical Center, Lackland Air Force Base, Texas, between January 1993 and December 1994. Extracted information included age, parity, indication for the loop electrosurgical excision procedure, histologic classification of the loop electrosurgical excision procedure specimen, margin status, and whether a "deep" (endocervical) pass had been performed. Follow-up data included findings of repeated cytologic examination, colposcopy, and biopsy if performed. RESULTS: The mean duration of follow-up for all women was 24 months. Margins were positive in 28%, with 73% of these being endocervical. The overall recurrent dysplasia rate was 31%, with a mean time to recurrence of 11.9 months. Participants with any positive margins had a higher recurrence rate than did those with negative margins (47% vs 26%; P = .009). High-grade lesions at the margin were more commonly associated with recurrence than were low-grade lesions relative to those with clear margins (high-grade lesion vs negative margins, 55% vs 26%; P = .003; low-grade lesion vs negative margins, 36% vs 26%; P = .34). Recurrence was not associated either with the performance of an endocervical pass or with the histologic diagnosis of the loop electrosurgical excision procedure specimen. CONCLUSION: With comprehensive long-term follow-up, positive margins on loop electrosurgical excision procedure specimens were shown to be a risk factor for recurrence of cervical dysplasia, particularly when high-grade lesions were seen at the margin. Recurrence was also considerable among women with negative margins. Women should be counseled regarding this risk, and the importance of follow-up should be emphasized.     

A short-term follow-up comparison of two trans-obturator tape procedures

The objective of the study was to compare the clinical outcomes at the short-term follow-ups of two novel transobturator mid-urethral sling procedures – the transobturator tape (TOT) procedure and the tension-free vaginal tape (TVT)-obturator procedure. The study cohort consisted two groups of 40 women with urodynamically proven stress urinary incontinence (SUI). The patients in one group underwent the TOT procedure, performed according to Delorme (Prog Urol 11:1306–1313, 2001); those in the second group underwent the TVT-obturator operation, performed according to de Leval (Eur Urol 44:724–730, 2003). Intra-operative diagnostic cystoscopy was not performed with either the TVT-obturator or the TOT procedures. The average follow-up was 12 months. The two patient groups were similar in terms of demographic and therapeutic criteria, except for patient age, which was significantly younger in the TVT-obturator group. Previously reported TVT-related operative complications, such as bladder penetration, intra-operative bleeding, field infection and post-operative pelvic floor relaxation, were not observed in patients of either group. Bowel and urethral injuries were also not recorded. The therapeutic failure rates were 10% for the TOT procedure and 5% for the TVT-obturator procedure. Urinary frequency and urgency post-operatively were reported in 25% of the TOT patients and 19% of the TVT-obturator patients, pelvic or vaginal pain affected 10% of the TOT and 5% of the TVT-obturator patients, while post-operative voiding difficulty was experienced by 12.5% of the TOT and 7.5% of the TVT-obturator patients. None of the above-mentioned differences between the two patient groups were of statistical significance. The TVT-obturator and TOT procedures, both minimally invasive, novel, mid-urethral sling procedures, seem to be safe, easy-to-perform and effective in treating female SUI. The patients of both study groups suffered less intra- and post-operative surgical complications than previously been reported in connection with the TVT operation. The TVT-obturator patients had fewer therapeutic failures, less post-operative urinary frequency and urgency, less pelvic pain and less voiding difficulty. All of these findings, however, had no statistical significance; consequently, long-term comparative data collection will be required before solid conclusions can be drawn on the superiority of either of these two operative techniques.     

Melanoma and pregnancy: a long-term follow-up

Treatment of the pregnant woman with melanoma is contentious. With the aid of a computerized melanoma register, in which pregnancy data can be recorded, 290 women with melanoma were reviewed (249 alive and 41 dead). Overall, 23 patients were pregnant at the time of diagnosis of melanoma, and another 23 became pregnant at some time after primary treatment of a melanoma. Pregnancy appears to have no significant influence on the survival of patients with melanoma, but it is recommended that pregnancy should be avoided for the first three years following excision of a melanoma.     

Laparoscopic surgery for endometriosis: a long-term follow-up

OBJECTIVE: To investigate if complete resolution of endometriosis by laparoscopic surgery is beneficial to postoperative fecundity, dysmenorrhea and dyspareunia. DESIGN: An observational comparative study on the outcome of laparoscopic surgery. Patients: Laparoscopically-treated symptomatic women with endometriosis (total n = 236); complete (n = 185) and incomplete (n = 51) surgery groups. MEASUREMENTS: Postoperative fecundity and symptom reduction. RESULTS: With whole populations, no surgical completeness-related difference was observed in cumulative pregnancy rates during the postoperative days 0-400 (cycle fecundity rate = 0.0319). Further accumulation of pregnant cases was followed in the complete surgery group (final cumulative pregnancy rate = 80%), but not in the counterpart group (p = 0.003). The similar result was obtained when only r-AFS classification stages III and IV were compared (p = 0.007). No r-AFS stage-related difference was observed in cumulative pregnancy rates when only patients of complete surgery were selected for comparison. The surgery reduced dysmenorrhea (84.7%) and dyspareunia (80.0%). CONCLUSIONS: Laparoscopic conservative surgery for endometriosis, especially when it is complete, increases fecundity and reduces disease-related symptoms, such as dysmenorrhea and dyspareunia.     

Brachytherapy for early endometrial carcinoma: a comparative study with long-term follow-up

The current study was undertaken to evaluate the effect of preoperative uterine or postoperative vaginal brachytherapy compared to no adjuvant therapy on the disease-free interval, sites of recurrence, and survival in favorable stage IB endometrial carcinoma.
One hundred and forty-six patients with FIGO grade 1 and 2 endometrial carcinoma and 1–33% myometrial invasion treated between 1974 and 1992 were retrospectively studied. The use of brachytherapy varied among the treating physicians during the study period. A Kaplan-Meier survival analysis was used to estimate disease-free survival and differences between treatment groups were evaluated with the Mantel-Cox statistic.
Recurrent disease occurred in 7 patients (5.3%). Vaginal recurrences accounted for 6 of the 7 sites of recurrences. Recurrences occurred in 1.3% of grade 1 vs. 8.7% of grade 2 tumors ( P = 0.04). Among 69 grade 2 tumors, recurrences occurred in 7.5% of those treated with brachytherapy vs. 10.3% of those not treated ( P = 0.68). Brachytherapy did not affect the disease-free or overall survival. No serious complications directly related to therapy occurred.
Vaginal recurrences occur even in early endometrial carcinoma. This study demonstrates no apparent benefit to brachytherapy. A larger study would be required to see a recurrence or survival difference.     

Prognosis of women with pelvic pain during pregnancy: a long-term follow-up study

STUDY DESIGN: A follow-up study of women with pelvic pain during pregnancy. OBJECTIVES: To evaluate prognostic factors for pelvic pain. METHODS: Out of a cohort of 870 pelvic pain patients, 598 women, who delivered less than 42 months prior to the follow-up measurement, were selected for follow-up. RESULTS: Data of 430 women were available for analysis with a mean follow-up duration of 18 months postpartum. Forty-three women still experienced moderate or severe pain and were seriously hindered in more than one activity. At intake symptomatic women experienced a higher overall severity of complaints, more walking deficiencies, and mentioned prepregnancy back pain more often and reported labor lasting longer than 18 h 2.5 times more often than asymptomatic women. Explained variance of these factors is small. CONCLUSIONS: Mean 18 months postpartum a small group had moderate or severe pain. Prepregnancy back pain, severity of complaints, and number of walking deficiencies at primary referral as well as duration of labor showed a significant relation with symptoms.     

Abdominal sacral colpopexy in patients with gynecologic cancer: report of 25 cases with long-term follow-up and literature review

OBJECTIVE: The aim of this study was to evaluate abdominal sacral colpopexy performed in conjunction with radical pelvic surgery for gynecologic cancer. METHODS: Over a 9-year period from 1990 to 1999 25 patients with invasive gynecologic cancer and concomitant uterovaginal or vaginal vault prolapse underwent surgery. These patients were compared to a series of 50 patients with no history of gynecologic cancer who underwent abdominal sacral colpopexy during the same period. RESULTS: All surgeries were performed without intraoperative complication. There was one failed vault suspension in each group and no postoperative mesh complications as a result of radical pelvic surgery or postoperative radiation or chemotherapy. CONCLUSION: Abdominal sacral colpopexy may be safely performed along with radical pelvic surgery for gynecologic cancer without an increase in intra- or postoperative morbidity even if patients require chemotherapy or radiation therapy after surgery.     

Major complications of operative gynecologic laparoscopy in southern Taiwan: a follow-up study

STUDY OBJECTIVES: This follow-up study examined the major complications among 4307 operative gynecologic laparoscopies. The overall complication rate and each individual category were compared with those of our previous study period. The clinical outcome and salvage procedures were correlated with the time of recognition and the severity of initial procedures in the individual injury type. DESIGN: Retrospective, comparative study based on medical record reviewing (Canadian Task Force classification II-3). SETTING: Tertiary teaching hospital, Chi Mei Foundation Hospital in southern Taiwan. PATIENTS: Records of women (n = 4307) aged 40.5 +/- 11.7 years (mean +/- SD [95% CI 40.1-40.5]) who underwent operative gynecologic laparoscopies from January 2000 through February 2006 were reviewed in this study. The complications were compared with those of our previous study based on 1507 laparoscopies performed between December 1992 and November 1999 for follow-up comparison. INTERVENTIONS: Gynecologic laparoscopic surgeries. MEASUREMENTS AND MAIN RESULTS: Thirty-four complications occurred in 31 patients requiring repair procedures, 3 of whom had multiple complications, with an overall complication rate of 0.72% (31/4307). There were 13 bladder injuries (0.30%), 7 bowel injuries (0.16%), 3 cases of internal bleeding (0.07%), 4 vaginal stump hematomas or abscesses (0.09%), 3 ureteral injuries (0.07%), 3 major vessel injuries (0.07%), and 1 trocar site hematoma (0.02%). In addition, there were 125 (2.88%) postoperative blood transfusions without additional operative intervention. The major complication rate decreased compared with that of the previous study (0.72% [95% CI 0.51%-1.02%] vs 1.59% [95% CI 1.07%-2.36%]; p = .005). The overall complication rates were not significantly different between laparoscopic hysterectomy (LH) group and non-LH group. However, bladder injury happened more frequently in the LH group, whereas bowel injury was more common in the non-LH group. In addition, the severity of the original injury, timing of recognition, and accompanying salvage procedures correlated with the clinical outcomes. CONCLUSION: The significantly decreased major complication rate, as compared with that of our previous study period, confirms the importance of experience accumulation and use of preventive maneuvers in reducing the complication rate. There were no significant differences among the individual injury category during these 2 study periods. The manifestations of bowel injury were highly variable and individualized. The accumulation of surgical experience with the aid of preventive maneuvers is helpful to reduce the complication rate significantly.     

Toxoplasmosis and pregnancy,with a long-term follow-up of the children

A prospective study was done on the incidence and effects of congenital infections with toxoplasmosis occurring during pregnancy. 3040 women were examined during pregnancy, 1821 of them were controlled at least twice, using the Sabin-Feldman dyetest. The frequency of infected children was 0.65%, total number 12. Of the 12 children only one child had clinical symptoms, she was squinting; three children had scars at the periphery of the retina, which were only found because of this study, and in one child without clinical symptoms the parasite was isolated from the placenta and the cerebrospinal fluid. The other children showed an asymptomatic form of the disease. A follow-up of the infected children for 7 years did not show serious abnormalities such as mental retardation, blindness, etc. No congenital infections were found in children with mothers who had had an old chronic infection. Statistically we did not find evidence that infections with toxoplasmosis of the mother occurring before pregnancy were the cause of abortion, habitual abortion or still-born children. One of the purposes of the study was to investigate the necessity for future routine control in all pregnant women on toxoplasmosis. We do not recommend this because of the problem in making a timely diagnosis, the unreliability of the medical treatment used until now and the expense of repeated serological control during all pregnancies.     

Dome-shaped high tibial osteotomy: a long-term follow-up study.

BACKGROUND: High tibial osteotomy (HTO) is a well-established treatment for unicompartmental gonarthrosis of the knee, but its durability and complications remain controversial. We previously introduced a novel dome-shaped HTO, and the long-term follow-up results using this technique are analyzed in this study. METHODS: We treated 25 varus knees in 22 patients with medial gonarthrosis, using a specially designed calibrated cutting jig along with rigid external fixation and early joint motion postoperatively. A total of 16 patients (19 knees) completed the study protocol and were followed up for 13-16 years (mean, 15 years). RESULTS: The surgery attempted to obtain 8 degrees valgus; the actual postoperative alignment averaged 12.4 degrees valgus, which decreased significantly to 7.8 degrees valgus after 5 years. The outcome as assessed by the Hospital for Special Surgery knee score was excellent or good in 18 knees at 5 years postoperatively, and in 13 knees at the final follow-up, showing a significant deterioration with time. Loss of correction with time was not correlated with the postoperative alignment achieved: at 5 years, loss greater than 2 degrees was found in 12 knees, but their mean corrected angle (11.8 degrees valgus) was not significantly different from that of the others (13.3 degrees valgus). Nor was the loss of correction correlated with the knee scores. The mean amount of joint motion after surgery did not change significantly with time: 124 degrees preoperatively and 114 degrees at the final follow-up. The patellar position also did not change from preoperative values during postoperative follow-up: mean Insall-Salvati index was 0.88 before and 0.90 5 years after surgery, neither showing patella baja. CONCLUSION: Dome-shaped HTO is a durable time-buying procedure for patients with unicompartmental medial gonarthrosis, and can avoid subsequent development of patella baja that may complicate further prosthetic arthroplasty.     

In vitro fertilization: a long-term follow-up after treatment failure

There is a considerable body of psychological research on women presenting for in vitro fertilization (IVF), but relatively little on the long-term adjustment of such women after unsuccessful treatment. This study examined the adjustment (4--9 years after treatment) of a sample (n = 76) of women whose treatment had failed. At follow-up, it was found that eight (10.53%) of the women had conceived naturally and 16 (21.05%) had become adoptive parents. In comparison with population norms, the women who had not subsequently conceived or adopted (n = 52) were found to rate themselves as more highly stressed (P < 0.001), but rated themselves as higher in self-esteem (P < 0.001). However, when women who remained childless after unsuccessful IVF were compared with those who subsequently conceived or adopted, the former group rated themselves as more stressed (P < 0.05), more depressed (P < 0.001) and with a lower satisfaction with life (P < 0.005) and lower self-esteem (P < 0.05). Women who wished to adopt but were unable to do so made a major contribution to this negative pattern. The study indicates that infertility long after failed IVF treatment contributes to psychological dysfunction. It highlights the need to prepare women better for treatment failure and to ensure appropriate counselling is available when further IVF treatment is no longer appropriate.     

Transcervical endometrial resection in women with menorrhagia: long-term follow-up

OBJECTIVE: Hysteroscopic endometrial resection is an innovative and conservative surgical technique considered, very often, as an alternative to hysterectomy. The aim of the study was to evaluate long-term efficacy of endometrial resection performed in women with menorrhagia. STUDY DESIGN: Retrospective study of 111 premenopausal women with menorrhagia, unresponsive to medical treatment, who underwent endometrial resection by resectohysteroscope (electrocautery technique supplied with a fundus rollerball electrode, with corneal areas, and with a 90 degrees loop for intrauterine walls and used with glycine 1% as distending fluid) between 1994 and 1999. RESULTS: Long-term follow-up questionnaires were completed in 106 cases, while 5 cases dropped-out (4.5%). The mean-age at menopause in our subjects was 52.8 years (17.6+/-18.4 months after operation). After 53.2+/-16.4 months, 82 patients (77.4%) showed a normal menstrual pattern or amenorrhea, while failure was recorded in 24 patients (22.6%) and 12/24 patients underwent hysterectomy. Percentage of success in the older population (>49 years) (94%) was significantly higher than in the younger population (70%). The histologic finding of only fibrosis (41.7%) correlated with failure of the technique. CONCLUSION: Our data suggest that endometrial resection by resectohysteroscope is an innovative and conservative but not exclusive surgical technique in selected younger women, while in older women endometrial resection nearly always resolves long-term menorrhagia.
