An anatomic and functional assessment of the discrete defect rectocele repair.

OBJECTIVE: The aim of this study was to describe the anatomic and functional results of the discrete fascial defect rectocele repair. STUDY DESIGN: Sixty-nine women underwent rectocele repair at Duke University Medical Center during a 3-year period beginning January 1, 1994. Repair was limited to reapproximation of discrete defects in the rectovaginal fascia, without levator plication or perineorrhaphy. Outcome measures included Pelvic Organ Prolapse Quantitation measurements, prolapse stage, and a symptom questionnaire. Univariate and nonparametric tests were used as appropriate. RESULTS: Before the operation 46% patients (32/69) reported constipation, 39% (27/69) reported splinting, 32% (22/69) reported tenesmus, and 13% (9/69) reported fecal incontinence. The median preoperative posterior Pelvic Organ Prolapse Quantitation stage was 2 (1-4). Pelvic Organ Prolapse Quantitation stage had improved for all but 2 women at 6 weeks. Eighteen percent (8/43) had recurrent rectoceles at 12 months. Mean values for the points describing the posterior vaginal wall improved >2 cm (P <.0001). Although perineorrhaphy was not performed, the genital hiatus decreased by 2. 3 cm (P <.0001), with no significant change in the length of the perineal body. Functional results mirrored anatomic results, with statistically significant improvements for all symptoms. CONCLUSIONS: The discrete defect rectocele repair provides anatomic correction of rectoceles with alleviation of associated symptoms for most women.

Urethral prolapse after collagen injection.

A woman who was treated for intrinsic urethral sphincteric deficiency with periurethral injection of glutaraldehyde cross-linked collagen had prolapse of the urethral mucosa and recurrence of incontinence. She subsequently required surgical resection and a fascia lata sling. This is the first known occurrence of this postinjection complication.

Reliability and correlation of measurements during and after bladder neck surgery. The Continence Program for Women Research Group.

OBJECTIVES: To assess the reliability of seven intraoperative measurements of the effects of bladder neck suspension and correlate these measurements with postoperative dynamic urethral obstruction, quantified as the cough-pressure transmission ratio. PATIENTS AND METHODS: Sixty women undergoing surgery for bladder neck hypermobility had seven measurements performed in duplicate: (i) the endoscopic appearance of the bladder neck: (ii) the bladder neck-retropubic surface distance (BN-RP distance); (iii) urethral axis; (iv) slow urethral pressure profilometry (UPP); (v) fast UPP; (vi) straining UPP; and (vii) dynamic UPP. Reliabilities were assessed by computing the intraclass correlation coefficient (R) for continuous data or Kappa statistic (K) for ordinal data. Pearson correlation coefficients were used to assess the relationships between the intra-operative measures and postoperative pressure transmission. RESULTS: The intra-operative reliabilities for maximum pressure, length and area from the three UPP techniques were high (R=0.88-0.98) as were those for urethral axis measurements (R=0.98). In contrast, reliabilities were poor for pressure transmission ratios (R=0.15-0.33), BN-RP distance (R=0.55), and endoscopic appearance (K=0.10). There were significant correlations of the pressures from the UPPs and intra-operative pressure transmission ratios with postoperative pressure transmission ratios; however, the poor intra-operative reliability of intra-operative pressure transmission limits their usefulness. None of the other measures correlated significantly with postoperative pressure transmission ratios. CONCLUSIONS: Of the measures studied, only intra-operative UPPs had both high reliability and good postoperative correlations.

Abdominal sacral colpoperineopexy: a new approach for correction of posterior compartment defects and perineal descent associated with vaginal vault prolapse.

OBJECTIVE: Our purpose was to assess a modification of abdominal sacral colpopexy in 19 patients. STUDY DESIGN: The rectovaginal space was dissected to the superior aspect of the posterior vaginal fascia still contiguous with the perineal body. Mersilene (Ethicon, Somerville, N.J.) mesh was sutured to this fascia and along the entire posterior vaginal wall. Patients with vault prolapse, perineal descent, and associated rectoceles or enteroceles are reported. Outcome measures included bowel symptoms and pelvic organ prolapse staging. Defecography was performed in three patients. Wilcoxon signed rank analysis was used for comparison of prolapse measures. RESULTS: Mean follow-up was 11 weeks. Bowel symptoms improved in 8 of 11 women. No subjects had greater than stage II prolapse postoperatively and median improvement in stage was 3 (range 2 to 4). The mean decrease in the genital hiatus measurement was 3.13 +/- 1.25 (range 2 to 6) cm. Postoperative defecography documented correction of rectoceles and enteroceles and improvement in perineal descent with straining. CONCLUSIONS: Abdominal sacral colpoperineopexy is effective surgery for vaginal vault prolapse associated with perineal descent and posterior vaginal defects.

The value of intraoperative cystoscopy in urogynecologic and reconstructive pelvic surgery.

OBJECTIVE: Our goal was to evaluate the role of intraoperative cystoscopy during surgery for pelvic organ prolapse and urinary incontinence. STUDY DESIGN: Charts of 224 consecutive patients who had intraoperative cystoscopy performed after urogynecologic surgery were reviewed. RESULTS: Nine injuries occurred that were unsuspected before cystoscopy, for an incidence of 4%. Six ureteral ligations occurred, four after Burch cystourethropexy and two after vaginal culdoplasty. Intravesical sutures were noted after two Burch procedures, and another injury occurred with passage of fascia lata through the bladder during a pubovaginal sling procedure. Eight injuries were managed by removal and replacement of the suture or sling with only one requiring ureteroneocystotomy. When patients with injuries were compared with those without, there were no statistical differences in demographic or surgical parameters. CONCLUSIONS: The potential for damage to the lower urinary tract is significant with complex urogynecologic surgery. Because of the increased and delayed morbidity associated with unrecognized injury, intraoperative surveillance cystoscopy should be considered a part of all such procedures.

Randomized prospective comparison of needle colposuspension versus endopelvic fascia plication for potential stress incontinence prophylaxis in women undergoing vaginal reconstruction for stage III or IV pelvic organ prolapse. The Continence Program for Women Research Group.

OBJECTIVE: Severe prolapse may mask potential genuine stress urinary incontinence in women. Some have suggested that a suspending urethropexy be performed in women who have potential genuine stress incontinence demonstrated by barrier reduction of the prolapse preoperatively. Our aim was to compare outcomes after prolapse surgery that included a formal bladder neck suspension with those operations that did not. STUDY DESIGN: This prospective randomized clinical trial assigned 32 women with bladder neck hypermobility and stage III or IV pelvic organ prolapse to receive either a needle colposuspension or bladder neck endopelvic fascia plication as part of the vaginal reconstructive surgery. Twenty-nine subjects underwent detailed clinical, anatomic, urodynamic, and quality-of-life evaluations before and 6 weeks and 6 months after surgery; 23 completed urinary diary and quality-of-life evaluations after a mean of 2.9 years. RESULTS: Needle colposuspension increased short-term complications without providing additional protection from de novo stress incontinence. Barrier testing before surgery predicted urethral sphincteric resistance after surgery; however, such testing neither predicted a patient's function after surgery nor indicated the need for a suspending urethropexy. The combination of a needle colposuspension with a sacrospinous ligament suspension predisposed to the early development of support defects of the upper anterior vaginal segment and to failure of bladder neck support. CONCLUSIONS: Preoperative barrier testing in women with severe prolapse is not useful in identifying individuals who require a suspending urethropexy. Needle colposuspension increases short-term complications, lacks durability, and may predispose to early and severe recurrent anterior prolapse when performed with a sacrospinous ligament vault suspension.

Voiding function following prolapse surgery. Impact of estrogen replacement.

OBJECTIVE: To identify factors that would predict postoperative bladder function in postmenopausal women undergoing pelvic reconstructive surgery for pelvic organ prolapse. STUDY DESIGN: Demographic variables and urodynamic measures were analyzed in respect to the length of postoperative bladder catheterization. RESULTS: Patient age, the presence of abnormal preoperative voiding patterns or elevated postvoid residuals, the route of surgical approach and the performance of urethropexy did not correlate significantly with the length of postoperative catheterization; only hormonal status did. Postmenopausal women using estrogen replacement therapy required significantly fewer days of catheterization than those who were not receiving estrogen replacement therapy. CONCLUSION: The use of preoperative estrogen replacement therapy is associated with a reduction in the length of postoperative bladder catheterization in women undergoing pelvic reconstructive surgery for pelvic organ prolapse.

Comparison of oral estrogens and estrogens plus androgen on bone mineral density, menopausal symptoms, and lipid-lipoprotein profiles in surgical menopause.

OBJECTIVE: To compare an oral estrogen-androgen combination with estrogens alone on bone, menopausal symptoms, and lipoprotein profiles in postmenopausal women. METHODS: Surgically menopausal women received oral esterified estrogens (1.25 mg), or esterified estrogens (1.25 mg) and methyltestosterone (2.5 mg) daily, for 2 years. Bone mineral density of the lumbar spine and hip, menopausal symptoms, lipoprotein profiles, and biochemical and hematologic indices were evaluated. RESULTS: Sixty-six patients were enrolled in the study. Both treatment regimens prevented bone loss at the spine and hip; combined estrogen-androgen therapy was associated with a significant increase in spinal bone mineral density compared with baseline (n = 24; mean score +/- standard error 3.4 +/- 1.2%, P < .01). In the estrogen group, high-density lipoprotein (HDL) cholesterol increased significantly and low-density lipoprotein cholesterol decreased significantly. Cholesterol, HDL cholesterol, and triglycerides decreased significantly in the estrogen-androgen group. Menopausal symptoms of somatic origin (hot flashes, vaginal dryness, and insomnia) were improved significantly by both treatments. Neither adverse hepatic effects nor significant safety or tolerance problems were reported in either group. CONCLUSION: Oral estrogen-androgen increased vertebral bone mineral density compared with pre-treatment values and relieved somatic symptoms. Safety indices, including lipoprotein levels, indicated that the combination was well tolerated over the 2 years of treatment.

Pelvic relaxation involving the middle compartment.

Loss of pelvic support involving the 'middle compartment' is manifested by herniation through the central pelvic floor in proximity to the intersection of an imaginary line from the public symphysis to the coccyx with another from one ischial spine to opposite ischial spine. Loss of middle compartment support may exist in association with 'anterior compartment' defects, 'posterior compartment' defects, or both. The severity of middle compartment relaxation ranges from mild uterine descensus to total uterovaginal prolapse when the uterus is present. When the uterus has been removed, it may range from vaginal vault descent to total vaginal eversion and includes all grades of enterocele. Middle compartment defects are usually not isolated. The recent literature relevant to middle compartment defects consists primarily of additional reports on surgical management, including continued modification and evolution of surgical techniques. Larger surgical series with longer follow-up periods have been reported. Cadaveric and histologic studies have appeared which have added to the understanding of normal anatomy and the disruptions thereof, which can cause middle compartment defects. Sophisticated diagnostic imaging techniques have generated preliminary reports which are of interest.

Pelvic inflammatory disease: findings during inpatient treatment of clinically severe, laparoscopy-documented disease.

OBJECTIVES: We evaluated the relationship between clinically severe pelvic inflammatory disease and laparoscopic diagnosis and grading, comparative treatment with clindamycin plus cefamandole or doxycycline, and a management protocol for inpatient pelvic inflammatory disease treatment. STUDY DESIGN: Thirty-three patients who met our clinical criteria for severe pelvic inflammatory disease underwent diagnostic laparoscopy. Pelvic inflammatory disease patients were randomized to double-blind treatment with clindamycin plus cefamandole or doxycycline within our management protocol; postdischarge oral antibiotics were omitted. RESULTS: Laparoscopy confirmed pelvic inflammatory disease in 23 (70%) patients; 10 (44%) had mild pelvic inflammatory disease by laparoscopic grading. Laparoscopic grade alone predicted necessary duration of therapy to response: mild pelvic inflammatory disease, 2.3 +/- 0.5 days; moderate pelvic inflammatory disease, 2.7 +/- 1.5 days; and severe pelvic inflammatory disease, 3.9 +/- 1.5 days (p less than 0.05). Using the management plan presented, response rates for both antibiotic regimens were 100%. CONCLUSIONS: Clinical diagnosis and grading of severe pelvic inflammatory disease has poor specificity. Laparoscopic grading of severity of pelvic inflammatory disease seems accurate. Both clindamycin plus cefamandole and clindamycin plus doxycycline are equally effective regimens for treatment of pelvic inflammatory disease and did not require supplementation after discharge. Our management plan is objective and practical; daily bimanual examination is the most sensitive indicator of persistent disease.

Abdominal sacral colpopexy in 163 women with posthysterectomy vaginal vault prolapse and enterocele. Evolution of operative techniques.

Abdominal sacral colpopexy with retroperitoneal interposition of a suspensory hammock between a prolapsed vaginal vault and the anterior surface of the sacrum was performed on 163 women for correction of vaginal vault prolapse during 18 consecutive years, from 1972 through 1989. Hysterectomy had previously been performed on 160 of the patients, 2 patients had congenital absence of the uterus, and 1 patient underwent vaginal hysterectomy at the time of the sacral colpopexy. The patients had been followed for 9 months to 18 years at this writing, with a median follow-up of 33 months. An additional 25 patients underwent successful sacral colpopexy since the end of the study period, but those data are not included here. Modifications of surgical techniques have evolved from our experience.

Necrotizing fasciitis in irradiated tissue from diabetic women. A report of two cases.

Two diabetic women with pelvic malignancies developed necrotizing fasciitis within the irradiation fields. Despite aggressive surgical and medical therapy, both died when their health became too unstable for them to tolerate further surgery to resect the residual infection. We attribute their poor outcome to several factors. First, postradiation tissue changes obscured the early clinical findings necessary for a prompt diagnosis and made the identification of adequate surgical margins difficult. Second, diabetic patients have increased susceptibility to this infection. Third, the cumulative effects of radiation, diabetes mellitus and other factors that are common in patients with gynecologic malignancy (advanced age, vascular disease, obesity) favor the development, progression and persistence of necrotizing fasciitis. Radiographic studies were helpful in defining the extent of the infection in one patient.

Choice of operation for genuine stress incontinence.

Surgery, the definitive treatment for most patients with genuine stress urinary incontinence, continues to evolve, as does the rationale for choice and application of given operations. The history of surgical progress to the present is well covered by Kohorn (Obstet Gynecol Clin North Am 1989, 16:841-852) and includes those operations that have progressively supplanted the anterior colporrhaphy on which the gynecologist traditionally depended. Emphasis on the secure retropubic placement of the bladder neck has led to the development of a number of modifications of open retropubic cystourethropexy, minimal incision needle suspension techniques, and various sling operations; recently reported modifications are acknowledged. The rationale of curing incontinence by restoring normal anatomy in the course of identifying and repairing discrete fascial defects has led to increased acceptance and use of the paravaginal or obturator shelf repair.

Thumbtack use for control of presacral bleeding, with description of an instrument for thumbtack application.

There is well-known difficulty in controlling hemorrhage from presacral vessels. There are reports on the use of thumbtacks to secure hemostasis in the face of presacral hemorrhage. This communication reports the successful use of thumbtacks to establish presacral hemostasis and describes a simple instrument designed to afford easier and more precise anterior sacral application of thumbtacks. The instrument is easy to make. It was devised because of difficulty encountered with manual placement of hemostatic thumbtacks and the absence of totally satisfactory delivery by any of the standard surgical instruments available.

Suprapubic teloscopy: extraperitoneal intraoperative technique to demonstrate ureteral patency.

A simple method for intraoperative visualization of the ureteral orifices to demonstrate ureteral function is described. This method, called suprapubic teloscopy because only the telescope of a cystoscope is used for visualization, allows intraoperative assessment without the need for completely closing the abdomen or repositioning the patient. The use of this equipment, standard in all operating suites, is detailed, and experience with 37 patients is presented.
