Encapsulated Enterococcus faecalis: role of encapsulation in persistence in mouse peritoneum in absence of mouse lethality

In 54 patients, transvaginal sacrospinous ligament fixation procedures were reviewed retrospectively. The mean operation time was 15 (12-45) min. The mean blood loss was 126 (110-175) cm3. The only intraoperative complication was a rectal laceration that was repaired primarily. The mean duration of follow-up was 28 (4-54) months. There were only 2 recurrent vaginal vault prolapses. There were 3 cases of cystocele (5.5%), 1 case of rectocele (1.8%), 5 cases of enterocele (9.2%), 3 cases of stress incontinence (5.5%), and 5 cases of dysparonia (9.2%). Sacrospinous ligament fixation can be used as an alternative treatment to vaginal hysterectomy in aged women with medical problems and young women suffering from genital descent with infertility. The procedure has the advantage of avoiding laparatomy, facilitating other vaginal repairs needed during the same operation, preserving vaginal function and shortening the time necessary for anesthesia and surgery.     

Bilateral transvaginal sacrospinous colpopexy: preliminary experience

OBJECTIVE: Our goal was to determine how often a transvaginal sacrospinous colpopexy procedure can be done bilaterally. STUDY DESIGN: Between August 1993 and July 1996, 66 patients were prospectively evaluated for uterine prolapse (19 patients) and posthysterectomy vaginal vault prolapse (47 patients). Twenty-six patients (25 with posthysterectomy vaginal vault prolapse) underwent an abdominal sacral colpopexy. The remaining 40 patients (18 with uterine prolapse, 22 with posthysterectomy vaginal vault prolapse) were preoperatively and intraoperatively assessed for a bilateral sacrospinous colpopexy. All patients with uterine prolapse underwent hysterectomy. RESULTS: In 10 of the 18 (56%) patients with uterine prolapse and in 16 of the 22 (73%) patients with posthysterectomy vaginal vault prolapse, bilateral suspension to the sacrospinous ligament was carried out. Follow-up has ranged from 6 to 40 months, and no recurrent vaginal cuff prolapses have been detected in any patients. In 3 patients, however, all in the bilateral fixation categories, distention cystoceles have developed; one patient has undergone a successful anterior colporrhaphy. CONCLUSIONS: The bilateral suspension is different from the unilateral suspension in that the former requires significant intraoperative judgment in its feasibility and in maintaining the width of the vaginal cuff to allow a bilateral suspension without tension. A bilateral fixation appears more attainable in a patient with posthysterectomy vaginal vault prolapse than in one with uterine prolapse.     

Expression and induction by IL-6 of the normal and variant genes for human plasminogen

A disposable suturing instrument is used in our surgical method for sacrospinous vault suspension to facilitate suture placement and retrieval. The pararectal space is dissected and the suturing device is placed just medial to the lateral third of the sacrospinous ligament-coccygeus muscle complex. Depression of the device's firing button advances a standard needle in a controlled circular path through the sacrospinous ligament-coccygeus muscle complex. The needle is retrieved with a straight-needle holder at a consistent location, 3 mm from the shaft of the instrument. A second suture is placed 0.5-1 cm medial to the first suture. If the holding strength for either suture is considered inadequate, the device is reloaded with the same suture and subsequent bites are taken. The procedure is completed using standard methods. In ten women treated for vaginal vault eversion, lateral dissection was completed in less than 10 minutes, and passage of two sutures through the sacrospinous ligament was accomplished in less than 2 minutes. There were no complications. One patient described mild buttock pain that resolved in 1 week. At 4-6 months' follow-up, vaginal examination with maximal straining demonstrated direct apposition of the vaginal wall to the sacrospinous ligament.     

Uterosacral ligament fixation for vaginal vault suspension in uterine and vaginal vault prolapse

OBJECTIVE: The purpose of this study was to determine the simplicity, safety, anatomic, and functional success of using the uterosacral ligaments for correction of significant complex uterine and vaginal vault prolapse by the vaginal route. STUDY DESIGN: Fifty women with uterine or vaginal vault prolapse with descent of the cervix or the vaginal vault to the introitus or greater were treated between 1993 and 1996 by the same surgeon with bilateral uterosacral ligament fixation to the vaginal cuff by the vaginal route. Included were patients with significant enterocele, cystourethrocele, rectocele, and stress urinary incontinence who had concomitant repair of coexisting pelvic support defects. An etiology of vaginal vault prolapse is discussed. RESULTS: Uterosacral ligaments were identified and used for successful vaginal vault suspension by the vaginal route in all 50 consecutive patients without subsequent failure or significant complications with a maximum follow-up of 4 years. One patient had recurrent stress urinary incontinence and two had asymptomatic cystoceles. Three patients had erosion of monofilament sutures at the vaginal apex. CONCLUSIONS: In these 50 patients with significant complex uterine or vaginal vault prolapse, uterosacral ligaments could always be identified and safely used for vaginal vault suspension by the vaginal route with no persistence or recurrence of vaginal vault prolapse 6 to 48 months after surgery. Excessive tension by the surgeon on tagged uterosacral ligaments at the time of hysterectomy may be an etiologic factor in vaginal vault prolapse.     

Dilatation of the left colon with a Foley catheter: an aid to staple anastomosis

Balloon dilatation of the left colon using a Foley catheter was performed in 26 patients prior to staple anastomosis. A 28-mm stapler was then used in six (23%) patients, a 29-mm in seven (27%), a 31-mm in eleven (42%) and a 33-mm in two (8%). Two anastomoses failed (7.9%) and one patient developed local recurrence. None of the remainder developed a symptomatic stricture. Flexible sigmoidoscopy was performed on 18 patients at least 3 months after surgery, revealing that one (5.5%) had developed an asymptomatic stricture. A 28-mm stapler had been used in this case. This technique of dilating the left colon with a Foley catheter is a useful aid to staple anastomosis in large bowel surgery.     

Anterior enterocele following cystectomy for intractable interstitial cystitis

PURPOSE: We clinically define the development of an anterior vaginal wall hernia following cystectomy for the management of intractable interstitial cystitis and establish surgical technique for its correction. MATERIALS AND METHODS: Of 27 women who underwent simple cystectomy and urethrectomy for intractable interstitial cystitis an anterior vaginal wall hernia developed in 3 (71, 56 and 61 years old) at 8, 14 and 16 months, respectively, postoperatively. Clinical appearance was similar to a midline cystocele but it contained bowel contents in the form of an anterior enterocele. Anterior enterocele was associated with vaginal vault prolapse in 1 patient who was treated with transvaginal sacro-spinous colpopexy. Patients with isolated anterior enterocele required a transabdominal approach with mobilization of the intestinal hernia contents and obliteration of the intervaginal abdominal wall space. RESULTS: At 12, 19 and 33 months following reconstruction prolapse has not recurred, and sexual function was restored in 1 patient. CONCLUSIONS: These cases suggest that an extended simple cystectomy performed on women with intractable interstitial cystitis may result in a weakening of the anterior vaginal wall with resultant anterior enterocele formation. When it is associated with vaginal vault prolapse a transvaginal technique may be considered but we prefer a transabdominal approach for an isolated anterior enterocele. Prevention of this entity may be warranted at the time of cystectomy.     

Carbon dioxide laser for laparoscopic enterocele repair

The use of the carbon dioxide (CO2) laser for laparoscopic enterocele repair was evaluated in four women with an enterocele as the only pathology. Three women had a large enterocele after earlier hysterectomy, and one young woman had a congenital enterocele. The technique consists of vaporizing the peritoneum of the enterocele; however, it is important first to delineate carefully the lesion's circumference because of the strong retraction during vaporization. Subsequently, a posterior culdotomy is performed taking care to restore the horizontal position of the upper vaginal axis by shortening the uterosacral ligaments, which are sutured together on the midline and the posterior vaginal wall. The (CO2) laser has the advantage that the superficial vaporization it produces is rapid (<5 min), safe, and completely bloodless. The shrinking during vaporization facilitates subsequent repair. Postoperative morbidity and recovery were uneventful for all patients. The (CO2) laser seems to have some advantages over sharp endoscopic resection of enteroceles. The relative simplicity of technique and the low postoperative morbidity suggest that endoscopy could become routine in pelvic floor surgery, improving diagnosis and complementing vaginal surgery while avoiding laparotomy.     

4-Defect repair of grade 4 cystocele

PURPOSE: The 4-defect repair of grade 4 cystocele corrects discrete and severe deficiencies of vesicourethral support. We describe this technique used during pelvic reconstruction in 130 women. MATERIALS AND METHODS: During a 3-year period 130 patients (age range 35 to 96 years) underwent repair of grade 4 cystocele using the 4-defect repair technique. Cystocele repair had been performed in 60 patients (46%) and hysterectomy had been performed in 85 (65%). A "goalpost incision" is used in the vaginal wall to facilitate separation of the wall from underlying perivesical fascia, entry into the retropubic space, and exposure of the urethropelvic ligament, cardinal ligament and perivesical fascia. The 4 polypropylene sutures are used to provide an anterior vaginal wall sling which is modified to incorporate perivesical fascia and cardinal ligaments. Central defect repair is achieved by approximation of the cardinal ligaments and midline plication of the perivesical fascia over absorbable mesh. RESULTS: A total of 112 patients were available for followup which ranged from 6 to 42 months (mean 21). Repair of grade 4 cystocele was accompanied by other transvaginal repairs in 94 patients (83%), including rectocele repair in 81, hysterectomy in 22 and enterocele repair in 31. Of the patients 92% had excellent objective and subjective results for anatomical cystocele repair. Of the patients with preoperative stress urinary incontinence 90% had excellent or good subjective results. De novo urge incontinence was seen in 7% of patients. CONCLUSIONS: The 4-defect repair technique relies on anatomical restoration of 4 distinct deficiencies of pelvic support and is highly effective for relief of symptoms of grade 4 cystocele.     

Globoside expression within the human placenta

PURPOSE: To validate a computer-based area calculation method of quantification of rectal evacuation by using defecography videotapes and to use that method to compare evacuation in constipated patients with that in control subjects. MATERIALS AND METHODS: For validation of the method, simultaneous defecography and weight measurements were compared in 36 patients with constipation or incontinence. Evacuation was calculated as the rate of change of the contrast medium-covered rectal area (percentage per second) or of the evacuated amount of contrast medium (percentage per second [relative] and grams per second [absolute]). After method validation, from a series of 215 consecutive constipated patients, individuals with an isolated radiologic diagnosis of intussusception greater than 0.6 cm (n = 27), rectocele greater than 2 cm (n = 19), enterocele (n = 12), or paradoxic puborectal muscle contraction (n = 12) were selected. Rectal evacuation in these groups was compared with that in 30 control subjects. RESULTS: Rectal evacuation rates measured at defecography correlated well with weighed amounts of evacuated contrast medium during the initial and total evacuation periods in 21 patients without contrast medium leak (r = 0.92, P < .001). Constipation overall, a rectocele greater than 2 cm, or paradoxic puborectal muscle contraction were associated with impaired evacuation (P < .001). CONCLUSION: Area calculations of rectal evacuation reflect rectal emptying. A rectocele greater than 2 cm or a paradoxic puborectal muscle contraction may be associated with obstructed defecation.     

Renal stone fragments following shock wave lithotripsy

BACKGROUND: To reinforce the staple line of the emphysematous lung and thereby prevent air leakage during thoracoscopic operations, we have developed a procedure of lung excision that uses a gelatin-resorcinol-formaldehyde-glutaraldehyde (GRFG) glue-spread stapler. METHODS: Formaldehyde-glutaraldehyde (FG) jelly is prepared by mixing FG fluid with 2.5% sodium carboxymethyl cellulose. The FG jelly is placed in the stapler groove and staple holes, and a gelatin-resorcinol (GR) mixture is applied. The GRFG glue-spread stapler was applied to emphysematous lung cutting during thoracoscopic operations in 10 cases. RESULTS: An adhesion-strength test showed no difference in glue adhesion between FG fluid and FG jelly. An experiment using swine lung showed that with this newly developed stapler, no resistance in firing occurred, and GRFG glue covered every staple hole. Clinical application in 10 cases with emphysematous lung demonstrated no air leakage from the staple line, even long after the operation. CONCLUSIONS: Emphysematous lung excision using the GRFG glue-spread stapler during thoracoscopic operations is useful in preventing air leakage from the staple line and is a simple, safe, and low-cost procedure.     

Influence of age and prostate-specific antigen on the chance of curable prostate cancer among men with nonpalpable disease

OBJECTIVE: Our aim was to retrospectively analyze the Mayo Clinic experience of descending perineum syndrome from 1987-1997. METHODS: Clinical records were abstracted for demographic features, risk factors, results of anorectal and defecation tests, and a mailed questionnaire evaluated outcome and current symptoms. RESULTS: All results are mean +/- SD. Clinically, 39 patients (38 women, one man), mean age 53+/-14 yr, presented with constipation (97%), incomplete rectal evacuation (92%), excessive straining (97%), digital rectal evacuation (38%), and fecal incontinence (15%). Laboratory tests showed anal sphincter resting pressure was 54+/-26 mm Hg, and squeeze pressure was 96+/-35 mm Hg; expulsion from the rectum of a 50-ml balloon required > 200 g added weight in 27%; perineal descent was 4.4+/-1 cm (normal < 4 cm) by scintigraphy. Scintigraphic evacuation, rectoanal angle change during defecation, and perineal descent were abnormal in 23%, 57%, and 78% of the patients, respectively. Associated features included female gender (96%), multiparity with vaginal delivery (55%), hysterectomy or cystocele/rectocele repair (74%). On follow-up, 64% responded; 17 of these 25 responders underwent pelvic floor retraining. At 2-yr median follow-up (range, 1-6 yr), 12 still experienced constipation or excessive straining; their perineal descent was greater than in patients who responded to retraining (p = 0.005). CONCLUSIONS: Descending perineum syndrome is identifiable by clinical history and examination, and the most prevalent abnormality on testing is perineal descent > 4 cm; rectal balloon expulsion is an insensitive screening test for descending perineum syndrome. Pelvic floor retraining is a suboptimal treatment for this chronic disorder of rectal evacuation; the extent of perineal descent appears to be a useful predictor of response to retraining.     

Constipation assessed on the basis of colorectal physiology

BACKGROUND: Constipation is a collective term for symptoms of different aetiologies and pathophysiologies. Our aim was to determine the prevalence of colorectal pathophysiology findings in a prospective series of patients with chronic constipation. METHODS: A total of 155 consecutive patients with chronic constipation underwent anorectal manometry, electromyography (EMG), the balloon expulsion test, colonic transit-time study, and defecography. RESULTS: All investigations were completed by 134 patients (112 females) with a median age 52 (range, 17-79) years. Patients were categorized on the basis of transit time and pelvic-floor function as belonging to 1 of 4 groups: slow-transit constipation (STC) (delayed transit time but normal pelvic-floor function, n = 28), pelvic-floor dysfunction (PFD) (pelvic-floor dysfunction and normal transit time, n = 32), combined slow transit and pelvic-floor dysfunction (STC + PFD) (n = 27), and normal-transit constipation (NTC) (normal transit time and normal pelvic-floor function, n = 47). There was no difference between diagnostic groups in anal sphincter pressures. However, rectal sensitivity to balloon distension was lower (P < 0.05) in patients with delayed transit. Paradoxical puborectalis contraction (PPC) was found on EMG in 42 patients (31%). The prevalence of PPC was higher (P < 0.001) in patients with pelvic-floor dysfunction. Inability to evacuate the rectal balloon was reported by 37% of patients with pelvic-floor dysfunction and 12% of patients with normal pelvic-floor function (P < 0.001). Rectocele was the only anatomic abnormality at defecography which was associated with poor rectal emptying. CONCLUSIONS: About two-thirds of our patients with constipation had objective evidence of delayed transit or pelvic-floor dysfunction. No single test could reliably identify any of the pathophysiologic subgroups of constipation.     

Colorectal surgery using a biofragmentable anastomotic ring

To compare the efficacy of the biofragmentable anastomotic ring (Valtrac-BAR, Davis and Geck, Medical Device Division, Danbury, CT, USA) with conventional anastomotic techniques, 30 patients who underwent colorectal surgery from August 1993 to March 1995 were retrospectively studied. The use of the BAR was also compared with conventional techniques including hand-sewn sutures in 30 patients and an end-to-end anastomosis (EEA) stapler in 24 patients. There were 17 men and 13 women in the BAR group with ages ranging from 37 to 80 years, 18 men and 12 women in the hand-sewn group with ages ranging from 41 to 82 years and 14 men and 10 women in the EEA group with ages ranging from 38 to 72 years. Surgical indications included: 25 colon cancers and five rectal cancers in the BAR group; 27 colon cancers and three rectal cancers in the hand-sewn group; and six colon cancers and 18 rectal cancers in the EEA group. There was no conversion to other anastomotic methods. Most of the patients tolerated a low-residual diet from the fifth post-operative day. No clinical leakage or stricture was noted. Only seven patients were aware of the passage of BAR fragments. The mean hospital stay was 14.1 days. There were no significant differences among these techniques in the return of bowel function, the incidence of surgical complications, including anastomotic leakage, or the length of hospitalization. BAR anastomosis was more time efficient than conventional techniques. Our results confirmed that BAR was an ideal sutureless alternative for anastomosis in colorectal surgery.     

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.     

High-dose-rate intracavitary brachytherapy in the management of cervical and vaginal intraepithelial neoplasia

PURPOSE: To assess the effectiveness of high-dose rate intracavitary brachytherapy (HDR-ICR) in patients with grade 3 cervical intraepithelial neoplasia (CIN-3) and grade 3 vaginal intraepithelial neoplasia (VAIN-3). METHODS AND MATERIALS: This was a retrospective analysis in 20 patients with CIN-3 (n = 14) or VAIN-3 (n = 6), average age 61.9 years, managed with HDR-ICR at Kanagawa Cancer Center. Two patients with CIN-3 with microinvasive foci and 11 other patients with CIN-3 were treated with HDR-ICR for cervical lesions. Six patients with CIN-3 after hysterectomy received HDR-ICR for recurrent or residual VAIN-3 lesions. One patient received radiation therapy for both CIN-3 and VAIN-3 lesions. All these patients but one were postmenopausal. RESULTS: Seventeen patients were treated with HDR-ICR alone, and three with combined external radiation therapy. The dose was calculated at Point A located 2 cm superior to the external os and 2 cm lateral to the axis of the intrauterine tube for intact uterus. For lesions of the vaginal stump, the dose was calculated at a point 1 cm superior to the vaginal apex or 1 cm beyond vaginal mucosa. In the 14 patients treated for CIN-3 lesions, the mean total dose of HDR-ICR was 26.1 Gy (range 20-30). Six patients received HDR-ICR for VAIN-3 lesions with mean dose of 23.3 Gy (range 15-30). At follow-up (mean 90.5 months; range 13-153), 14 patients were alive and 6 had died owing to nonmalignant intercurrent disease. No patient developed recurrent disease. Rectal bleeding occurred in three patients, but this symptom subsided spontaneously. Moderate and severe vaginal reactions were noted in two patients, in whom the treatment had included the entire vagina. CONCLUSIONS: HDR-ICR can be employed as the primary management strategy for postmenopausal women with CIN-3. In intraepithelial neoplasia involving the vaginal wall after hysterectomy, HDR-ICR should be considered as an alternative to total vaginectomy.     

Successful peer review of courses: a case study

PURPOSE: In patients with early cervix carcinoma, both radiotherapy and surgery or combined modalities provide effective therapies. In the two last modalities, recommended surgery is radical hysterectomy. The purpose of this prospective study was to assess the value of a limited vaginal hysterectomy after brachytherapy in patients without any unfavorable prognostic factor. PATIENTS AND METHODS: Twenty-two patients (stage Ia2 with vascular invasion: three patients, stage Ib 1:19 patients) with 1 cm median maximal tumor size and with previous negative laparoscopic lymphadenectomy (median number of lymph nodes: 12) underwent a limited vaginal hysterectomy 6 weeks after utero-vaginal brachytherapy. RESULTS: Two mild intra-operative complications were noted. Venous hemorrhage (100 mL) occurred in one patient during lymphadenectomy and another patient presented bladder injury during hysterectomy. These two complications were successfully controlled with no need for laparotomy. Only one late complication was observed: bladder grade G2 (b). With a 29 months follow-up (20-48 months), no recurrence was reported. CONCLUSION: These results appear promising in patients with very early cervix carcinoma but remain to be confirmed on a larger scale.     

Laparoscopy-assisted and -prepared hysterectomy. A series of 80 cases

OBJECTIVE: Our objective was to determine the interest of laparoscopic assisted vaginal hysterectomy. STUDY DESIGN: Between January 1991 to december 1994, 80 patients had laparoscopically assisted vaginal hysterectomy. We reviewed with particular emphasis characteristic indications, complications. RESULTS: Eighty were performed as laparoscopically assisted vaginal hysterectomy. 14 patients (17.5%) had laparotomy conversion; because of size of uterus in 3 cases, suspected ovarian tumor in 3 cases. Pelvic adherences in 4 cases, urinary tract injuries in 1 case, hypercapnia in 1 case, hemorrhage in 2 cases. 9 patients experienced febrile morbidity and 1 urinary infection. 1 patient received 2 units of packed red blood cells. The hospital stay was 5 days for laparoscopically assisted vaginal hysterectomy versus 5.9 for laparotomic hysterectomy. CONCLUSION: Laparoscopically assisted vaginal hysterectomy offers a technique to convert certain abdominal hysterectomies into vaginal hysterectomies with a 17.5% laparoconversion rate.     

Surgical evaluation and management of refractory constipation in older children

Chronic constipation is a common childhood problem that accounts for 3% to 5% of pediatric visits and 10% to 25% of referrals to pediatric gastroenterologists. The etiology of constipation can be elusive, and extensive investigation often fails to identify a specific cause. The authors conducted a 5-year retrospective review of the patients referred for deep transanal rectal biopsy to determine the usefulness of this procedure in the evaluation and subsequent surgical management of refractory constipation. Specimens obtained by transanal rectal biopsy established a diagnosis for 30 of the 70 patients, and 17 of these 30 had subsequent procedures in the treatment of their constipation. The authors conclude that transanal rectal biopsy identifies a significant number of patients with previously unidentified neuroenteric disorders who may benefit from additional surgery in the treatment of constipation refractory to medical management.     

Primary surgery for stage IB-IIA cervical cancer, including short-term and long-term morbidity and treatment in pregnancy

Radical hysterectomy and pelvic lymphadenectomy are indicated for the treatment of cervical carcinoma that is localized clinically to the cervix and upper vagina. Intraoperative complications have been reported in 1.1%-7.4% of patients. Long-term complications include bladder dysfunction (2% at 3 years), urinary fistula (vesical, 0.8%; ureteral, 1.2%), stress urinary incontinence (29%), ureteral stricture (1%), rectal dysfunction (80%), severe constipation (5.3%), lymphocysts (20% by ultrasonography; 2% clinically), and lymphedema (10%). The operative mortality is 0.7%. The 5-year survival rate for patients with stage IB disease is 85.7% and for stage IIA is 69.6%. The recurrence rate is 27.2%. Recurrences are distributed equally between the pelvis and extrapelvic sites. Radical hysterectomy is the treatment of choice for pregnant patients with early cervical cancer. It affords termination or delivery of the pregnancy at the same time that the treatment is provided. For patients with stage I disease treated with radical hysterectomy, the survival rate is 92.1%.     

Euthanasia and the terminally ill: can the civil killing of others be eroded?

Hysterectomy is associated with severe constipation in a subgroup of patients, and an adverse effect on colonic motility has been described in the literature. The onset of irritable bowel syndrome and urinary bladder dysfunction has also been reported after hysterectomy. In this prospective study, we investigated the effect of simple hysterectomy on ano-rectal physiology and bowel function. Thirty consecutive patients were assessed before and 16 weeks after operation. An abdominal hysterectomy was performed in 16 patients, and a vaginal procedure was performed in 14. The parameters measured included the mean resting, and maximal forced voluntary contraction anal pressures, the recto-anal inhibitory reflex, and rectal sensation to distension. In 8 patients, the terminal motor latency of the pudendal nerve was assessed bilaterally. Pre-operatively, 8 patients were constipated. This improved following hysterectomy in 4, worsened in 2, and was unchanged in 2. Symptomatology did not correlate with changes in manometry. Although, the mean resting pressure was reduced after hysterectomy (57 mmHg-53 mmHg, P = 0.0541), the maximal forced voluntary contraction pressure was significantly decreased (115 mmHg-105 mmHg, P = 0.029). This effect was more pronounced in those with five or more previous vaginal deliveries (P = 0.0244, n = 9). There was no significant change in the number of patients with an intact ano-rectal inhibitory reflex after hysterectomy. There was no change in rectal sensation to distension, and the right and left pudendal nerve terminal motor latencies were unaltered at follow-up. Our results demonstrate that hysterectomy causes a decrease in the maximal forced voluntary contraction and pressure, and this appears to be due to a large decrease in a small group of patients with previous multiple vaginal deliveries.
