Enterocele: what is the clinical implication?

PURPOSE: Because of the rarity of diagnosis, the clinical implication of enterocele remains unclear. This study was designed to clarify the characteristic symptoms and the role of surgical treatment for enterocele. METHODS: We reviewed a defecography database prospectively maintained from 1998 to 2004. Defecography was performed with oral barium to opacify the small bowel in all patients. Enterocele was defined as the small bowel falling down beyond the level of the vaginal vault practically, it was <3 cm from the anorectal angle in the lateral view. Patients' clinical information was collected using a questionnaire. Patients with intractable symptoms underwent surgical repair. RESULTS: Among 912 patients on defecography, 104 patients (11 percent) revealed an enterocele (18 males mean age, 63 (range, 21-86) years). Concomitant abnormal findings, such as perineal descent, rectocele, and rectal intussusception, were encountered in 79 patients (76 percent). Only 25 patients (24 percent) had isolated enteroceles. Characteristic symptoms were difficulty emptying (61 patients), postevacuation discomfort (54 patients), and pelvic pain (28 patients). Eleven patients (10 females) underwent Douglas' pouch repair. Three of the 11 patients reported complete resolution of pelvic pain. The remaining eight patients experienced reduced symptoms, mainly resolution of pelvic heaviness, but still had difficulty emptying or postevacuation discomfort. CONCLUSIONS: This study suggests that the characteristic symptoms of enterocele are: difficulty emptying, postevacuation discomfort, and pelvic pain or heaviness. Selected patients with pelvic pain rather than obstructed defecatory symptoms might benefit from surgical repair.

Colorectal motor and sensitivity features in patients affected by ulcerative proctitis with constipation: a radiological and manometric controlled study.

BACKGROUND AND AIM: Constipation may be present in ulcerative proctitis (UP), but its pathogenesis has not yet been evaluated. The aim of this article is to investigate functional and morphologic features of the anorectal region in patients with UP and constipation. MATERIALS AND METHODS: Eleven patients with quiescent clinical, endoscopic, and histological UP and constipation and 10 patients with functional constipation (FC) underwent radiologic evaluation of intestinal transit time, anorectal manometry, and defecography. Transit time was measured with radiograms at 72 h after ingestion of radiopaque markers. Manometry was carried out using a continuous perfused catheter and a balloon inflated with increasing volumes of air. Defecography was performed after the injection of a barium-sulfate solution in the rectum, with the registration of videotapes during straining, squeezing, and evacuation. RESULTS: Manometry showed in UP significantly lower values of rectal compliance than those in FC (3.10 and 5 mL/mmHg, respectively) (P = 0.03). Rectal sensitivity threshold was increased but without significant differences in UP and FC (30 and 50 mL air, respectively). At defecography, the median value of rectosacral space was increased in UP in comparison with FC (1.30 vs 0.8; P = 0.002). Lateral rectal diameter in UP was lower than in FC (6 and 8.8 cm, respectively; P = 0.016). Nonsymptomatic rectocele, mucosal prolapse, descending perineum, and abdominopelvic dyssynergy were equally present in UP and FC. The majority of UP patients showed a prolonged intestinal transit time similar to FC patients, and, more frequently, they showed low transit in the left colon in comparison with the right colon in comparison with FC patients. CONCLUSIONS: This study suggests that constipation in UP may be correlated with rectal fibrosis, which reduces the transit of stools from the left colon. The concomitance of asymptomatic anorectal organic or functional alteration may contribute to worsen constipation.

Investigation of the utility of colorectal function tests and Rome II criteria in dyssynergic defecation (Anismus).

Although 30-50% of constipated patients exhibit dyssynergia, an optimal method of diagnosis is unclear. Recently, consensus criteria have been proposed but their utility is unknown. To examine the diagnostic yield of colorectal tests, reproducibility of manometry and utility of Rome II criteria. A total of 100 patients with difficult defecation were prospectively evaluated with anorectal manometry, balloon expulsion, colonic transit and defecography. Fifty-three patients had repeat manometry. During attempted defecation, 30 showed normal and 70 one of three abnormal manometric patterns. Forty-six patients fulfilled Rome criteria and showed paradoxical anal contraction (type I) or impaired anal relaxation (type III) with adequate propulsion. However, 24 (34%) showed impaired propulsion (type II). Forty-five (64%) had slow transit, 42 (60%) impaired balloon expulsion and 26 (37%) abnormal defecography. Defecography provided no additional discriminant utility. Evidence of dyssynergia was reproducible in 51 of 53 patients. Symptoms alone could not differentiate dyssynergic subtypes or patients. Dyssynergic patients exhibited three patterns that were reproducible: paradoxical contraction, impaired propulsion and impaired relaxation. Although useful, Rome II criteria may be insufficient to identify or subclassify dyssynergic defecation. Symptoms together with abnormal manometry, abnormal balloon expulsion or colonic marker retention are necessary to optimally identify patients with difficult defecation.

Defecographic study of rectal evacuation in constipated patients and control subjects.

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.

Patients' perception of tests in the assessment of faecal incontinence.

The objective of this study was to evaluate patient perception of endoanal MRI compared with defecography and anorectal functional testing in the workup of patients with faecal incontinence. Consenting consecutive patients underwent a standard testing protocol consisting of endoanal MRI, defecography and anorectal function combination. Patient experience was evaluated with a self-administered questionnaire, addressing anxiety, embarrassment, pain and discomfort, each measured on a 1 (none) to 5 (extreme) point-scale. Patients were also asked to rank the three tests from least to most inconvenient. Statistical analysis was performed with parametric tests. Data from 211 patients (23 men; mean age 59 years (SD+/-12)) were available. MRI had the lowest average score for embarrassment and discomfort (1.6) and defecography the highest (1.9 and 2.0, respectively) (p<0.0001, tested with general linear model for related samples). The average pain score was lowest for MRI (1.4) and highest for the anorectal function combination (1.7) (p<0.0001). Level of anxiety was highest for MRI (1.6 versus 1.4; p = 0.03). MRI was scored as least inconvenient by 69% of patients. Endoanal MRI was scored as least inconvenient. However, the differences in patient burden between the three diagnostic tests were small and absolute values were low for all tests. Patient perception will not be a key feature in determining an optimal diagnostic strategy in faecal incontinence.

Defecographic assessment after colonic J pouch-anal anastomosis.

Colonic J pouch anal anastomosis is widely employed after rectal resection. In the 36 patients who participated in our retrospective study, although postoperative continence was retained/maintained in each individual, a survey questionnaire indicated some difficulties in neoanorectal function. Therefore, defecography was performed in 20 of these patients. Patients experiencing soiling were found to have an increased ano-pouch angle and pelvic floor descent. Loss of sensation and incomplete evacuation were also associated with an abnormally large pelvic floor descent. However, stool frequency, urgency, and the need for medication showed no correlation with any of the defecography parameters. These findings thus suggested that the puborectal muscle and the levator ani muscle played an important role in postoperative function. Defecography was also found to provide a dynamic assessment of the postoperative state of colonanal reconstruction.

Selection criteria for anterior rectal wall repair in symptomatic rectocele and anterior rectal wall prolapse.

PURPOSE: This study was undertaken to determine the outcome and changes produced by an endorectal anterior wall repair in objective functional parameters using anorectal manometry and defecography and to asses their usefulness in the selection of patients for the operation. METHODS: Between 1986 and 1990, we performed a prospective study of 76 consecutive patients with symptomatic rectocele and/or an anterior rectal wall prolapse. All patients were studied prospectively according to a fixed protocol. Standard questionnaire, defecation diary, clinical examination, defecography, and anal manometry were performed preoperatively and three to four months postoperatively. RESULTS: Three months postoperatively, 38 patients (50 percent) had no complaints at all (excellent result), 32 (42 percent) had only a minor complaint (good result), and in 6 patients (8 percent) the complaints were essentially unchanged (unsatisfactory result). After one year, similar figures were obtained. The postoperative mean stool frequency in all patients after three months was significantly increased (P < 0.05) but not after one year. Postoperative defecographies showed a complete absence or significant diminution of the rectocele at three months and were significantly correlated with relief of symptoms. An inverse correlation was found between improvement in incontinence grade after operation and (larger) preoperative volume at which urge to defecate was elicited, making it a good predictor of improvement in incontinence by the operation. CONCLUSIONS: The anterior rectal wall repair positively influences rectal sensation in patients with incontinence and/or obstructed defecation caused by a rectocele and/or an anterior rectal wall prolapse. Anorectal manometry was useful in studying the beneficial physiologic effects of the endorectal repair. In patients with no previous pelvic surgery, a large urge to defecate volume is a good predictor of a good clinical outcome.

Enterocele is correctable using the Ripstein rectopexy.

PURPOSE: About one-third of the patients with rectal prolapse or rectal intussusception have concurrent enterocele at defecography. The purpose of this study was to evaluate the effect of the Ripstein procedure on the concurrent enterocele and to study the outcome of the procedure with respect to the patients' symptoms. METHODS: Twenty-two patients with enterocele and either rectal prolapse or rectal intussusception at defecography were treated using the Ripstein procedure. Postoperatively, the patients were evaluated with clinical examination (22 patients) and defecography (16 patients). RESULTS: None of the patients had recurrence of enterocele, rectal prolapse, or intussusception at postoperative follow-up. Continence was improved in 15 of 16 incontinent patients. Emptying difficulties were unchanged in eight patients, improved in five patients, and had deteriorated in four patients. CONCLUSIONS: Enterocele is corrected by using the Ripstein rectopexy. Persisting defecation difficulties after the Ripstein procedure are unlikely to be secondary to enterocele. The Ripstein procedure can be an alternative in the treatment of enterocele, as a majority of these patients also have rectal prolapse or rectal intussusception.

Excellent outcome using selective criteria for rectocele repair.

PURPOSE: The aim of this study was to review our experience with patients with rectoceles using very selective criteria for operative repair and to critically review our surgical results. METHODS: This is a review of patients selected for rectocele repair between 1989 and 1994. RESULTS: Two hundred seventy-nine patients were evaluated for pelvic outlet symptoms in our clinic. Defecography was performed in 180 patients; rectocele was seen in 143 patients (79 percent; 135 females and 8 males). On physical examination, 132 patients had a palpable rectocele (73 percent). Rectocele repair was recommended for 35 patients (13 percent); 33 (32 females and 1 male) underwent this procedure. Mean age was 55 (range, 16-78) years. Although many patients complained of constipation, incontinence and pelvic pain, in these 33 patients criteria for repair included the sensation of a vaginal mass or bulge that required digital support and/or rectal digitizing for evacuation (58 percent), retention of barium in the rectocele on defecography (55 percent), or a very large rectocele with internal anterior rectal wall prolapse (6 percent). A hysterectomy had been performed previously in 47 percent of women repaired. Rectocele repair was performed by a standard transanal approach in 31 patients and transabdominally in 2 patients. Hospital stay averaged 3.7 (range, 1-8) days. Few postoperative complications occurred; urinary retention was the most common (18 percent). All patients were followed postoperatively, and 26 patients (79 percent) answered a standardized questionnaire. Mean follow-up was 31 (range, 5-64) months. Eighty percent of patients questioned who initially complained of a vaginal mass or bulge reported complete resolution (significant improvement by the sign test, P < 0.5). Subjectively, 92 percent of patients questioned reported improvement in their preoperative symptoms and satisfaction with the operation. CONCLUSION: Rectoceles are frequently identified during defecography, which is performed for pelvic floor complaints, yet are often asymptomatic. In contrast to other recent reports of rectocele repair, our data indicate that careful selection of patients using specific criteria may result in very good clinical results.

Viscous fluid expulsion in the evaluation of the constipated patient.

PURPOSE: The aim of this study was to evaluate a viscous fluid expulsion test as a method for quantifying rectal outlet obstruction. METHODS: We examined the ability of 30 severely constipated patients and 40 healthy control subjects to expel a viscous fluid simulating feces. RESULTS: Constipated patients with defecographic rectal retention expelled a significant lower viscous fluid volume compared with controls (P < 0.0001). Considering the viscous fluid expulsion test to be positive if the patient expelled less than 160 ml of fluid (lower 95 percent confidence value in healthy controls) and using the presence of defecographic rectal outlet obstruction as a reference, the predictive value of a negative viscous fluid expulsion test was 100 percent, the predictive value of a positive test was 67 percent, and sensitivity and specificity was 100 percent and 82 percent, respectively. The viscous fluid test identified symptomatic outlet obstruction in almost twice as many patients as did defecography. Some patients, however are-despite their obstructive symptoms-able to evacuate their rectum when examined in the laboratory. CONCLUSION: The viscous fluid expulsion test is a simple, reproducible, nonionizing, and low-cost method of quantifying rectal outlet obstruction. A positive test result should lead to a defecography, whereas a negative test result renders defecography dispensable and spares the patient from pelvic radiation.

Defecographic evaluation of dynamic graciloplasty for fecal incontinence.

PURPOSE: A prospective defecographic study was performed to evaluate the anorectal physiology of dynamic graciloplasty (gracilis muscle transposition and subsequent implantation of an electric stimulator) for treatment of fecal incontinence. METHODS: From November 1986 until May 1993, 38 consecutive patients with incapacitating fecal incontinence were treated with "anal dynamic graciloplasty." Defecography was performed before and after surgical procedures. Defecographic data (anorectal angle, perineal descent, anal canal length, anal canal width, and anal leakage) were correlated with respect to clinical outcome and anal manometry. RESULTS: Fecal continence was achieved in 24 patients, which correlated significantly with no leakage of barium contrast during defecography (P < 0.01, Kruskal-Wallis one-way analysis of variance). In addition, minimum anal canal width decreased from 7 mm before surgery to 1 mm after dynamic graciloplasty (P < 0.01, paired Student's t-test). CONCLUSION: Defecography is an efficient method to evaluate dynamic graciloplasty for fecal incontinence.

Balloon expulsion test facilitates diagnosis of pelvic floor outlet obstruction due to nonrelaxing puborectalis muscle.

We compared balloon expulsion, defecography, colonic transit times, anal manometry, and electromyography in 21 patients with severe constipation. Defecography demonstrated nonrelaxation of the sphincter during straining in all patients. Only 12 patients were unable to expel a balloon. Colonic transit was normal (five) or showed rectosigmoid delay (seven). All 12 patients were offered biofeedback. The nine patients able to expel a balloon had normal colonic transit (six) or colonic inertia (two). Rectosigmoid delay was due to severe intussusception in one patient. Anal manometry and pudendal nerve latencies revealed no difference between those who could and those who could not expel a balloon. Balloon expulsion seems to be a more reliable way to diagnose pelvic floor outlet obstruction due to nonrelaxation of the puborectalis muscle. Nonrelaxation of the sphincter on defecography should be correlated with balloon expulsion and colonic transit studies.

Diagnosis of disturbances of continence and defecation.

Defecography was performed in 60 patients with disorders of continence or defecation in whom previous investigative procedures had not revealed any abnormality that could explain the disorder. A correct diagnosis was made in 47 patients (78%). Defecography appears to be a suitable procedure to detect functional disturbances of defecation. Since anterior rectal wall abnormalities such as colitis cystica profunda and solitary rectal ulcer were seen in eight patients, it is suggested that these abnormalities are a result of functional disorders of defecation. Furthermore, the function of the pelvic floor musculature can be assessed by defecography in order to determine the cause of fecal incontinence.

Diagnosis of functional disorders of defecation causing the solitary rectal ulcer syndrome.

The solitary rectal ulcer and colitis cystica profunda are different manifestations of the solitary rectal ulcer syndrome. The cause of solitary rectal ulcer syndrome remains unknown. Since defecation disorders are common among patients with solitary rectal ulcer syndrome, defecography is indicated. Defecography was performed on 19 patients with solitary rectal ulcer syndrome. In five patients, the spastic pelvic floor syndrome had occurred. Twelve patients had internal intussusception of the rectum, and one patient had an anterior rectal wall prolapse. In one patient, no abnormalities could be detected. These abnormalities led to severe straining, which can damage the anterior rectal wall. Findings strongly support the hypothesis that solitary rectal ulcers are traumatic lesions caused by straining. Defecography is a suitable procedure for detecting the causative disorder of defecation and for selecting patients for treatment.

Rectocele is associated with paradoxical anal sphincter reaction.

Rectocele is a frequent finding in constipated patients. However, constipation is not always relieved by rectocele repair, which may be due to other overlooked reasons for constipation. The study was designed to investigate patients with rectocele, in order to elucidate concomitant colorectal disorders and their association with rectocele. One hundred and twelve female patients suffering from severe constipation and rectal emptying difficulties were investigated using defecography, electrophysiology, anorectal manometry and colon transit time. Fifty-six patients with rectocele demonstrated by defecography were compared with 56 patients without rectocele, but with other abnormal findings at defecography. The frequency of paradoxical anal sphincter reaction (PSR) was higher in patients with rectocele (60%) than in patients without rectocele (24%). The present study supports an association between rectocele and PSR. We suggest that constipated patients with a rectocele should be investigated thoroughly before rectocele repair is considered. Further studies on the effect of biofeedback training in patients with rectocele and PSR are indicated.

Transvaginal anterior levatorplasty with posterior colporrhaphy for symptomatic rectocele.

BACKGROUND: We evaluated functional and morphological outcomes of transvaginal anterior levatorplasty with posterior colporrhaphy for symptomatic rectocele. METHODS: Ten women (median 68 years) underwent transvaginal anterior levatorplasty with posterior colporrhaphy for symptomatic rectocele. Symptoms and continence were monitored before and after surgery. Manovolumetric study and defecography were performed in 9 of 10 patients before and 3-6 months after surgery. Twenty-one females without anorectal diseases were used as controls in manovolumetric study. The patients were followed up after a median of 89 months (range, 3-103). RESULTS: Main symptoms (defecatory disorders in 9 patients, vaginal mass in 6, perineal discomfort in 2) disappeared after surgery. Six patients performed digitation preoperatively and gave up digitation on defecation after surgery. Stool incontinence disappeared in 4 of 5 preoperatively incontinent patients (Cleveland clinic score, 5-12) and continence score improved from 5 to 2 in the remaining patient. Three patients with urinary cough incontinence preoperatively did not experience incontinence after surgery but cough incontinence occurred occasionally in an 81-year-old patient postoperatively. Rectocele demonstrated on defecography disappeared postoperatively in all 9 patients who underwent defecography. High threshold volume and maximum tolerable volume, which were observed preoperatively, decreased to control levels after surgery. CONCLUSION: Transvaginal anterior levatorplasty with posterior colporrhaphy might be an option for symptomatic rectocele to improve anorectal and urinary dysfunctions with morphological disorders.

Which surgical approach for rectocele? A multicentric report from Italian coloproctologists.

The most effective surgical technique for rectocele has not yet been clearly established. A retrospective multicentric study was carried out to compare the long-term results of 3 endorectal techniques (Block, Sarles and stapled) and the perineal levatorplasty, alone and in association, in a series of patients with symptomatic rectocele. From January 1992 to December 1999, 2212 patients with defecation disorders were referred to 5 Italian coloproctology units. An anterior rectocele was clinically diagnosed in 1045 patients and confirmed with defecography. On the basis of clinical and radiological parameters, 317 patients (312 women; mean age, 52.4+/-20.1 years) were selected for surgery. Group 1 consisted of 141 patients (136 women; mean age, 50.4+/-18.8 years) who were submitted to endorectal operations. Group 2 consisted of 126 women (mean age, 52.5+/-19.7 years) who received perineal levatorplasty. Finally, 50 women (mean age, 54.3+/-21.9 years) in Group 3 received endorectal operations associated with perineal levatorplasty. A total of 269 patients were followed postoperatively (mean period, 24.2+/-3.1 months, 27.5+/-5.4 months and, 22.8+/-2.8 months, respectively) with the same questionnaire and clinical examination. Three months after surgery, a defecography examination and anorectal manometry were performed in 136 and 132 patients, respectively. Operative time, hospital stay and time to return to work were significantly higher in Group 3 (p<0.001). There was one death in Group 3 due to severe sepsis. Main postoperative complications were: in Group 1, hemorrhage (7.8%, all Sarles), dehiscence of the endorectal suture (5.0%, all Block), distal rectal stenosis (2.1%, 1 stapled, 2 block), and rectovaginal fistula (1.4%, all Sarles); in Group 2, delayed healing of the perineal wound (16.4%); in Group 3 delayed healing of the perineal wound (22.0%), hemorrhage (6%, all Sarles), dehiscence (4.0%), stenosis (2.0%). 17.3% of patients of Group 2 and 22.5% of Group 3 complained of dyspareunia. Postoperative defecography showed a complete absence of the rectocele in 44.1% of patients and reduction of size in the others, without significant differences among the three groups. Manometric pattern was not significantly modified by surgery. Significant symptoms recurred in 5.9% of the patients in Group 1, 6.4% in Group 2, and 5.0% in Group 3. Perineal levatorplasty did not significantly improve obstructed defecation, as it did not allow to excise the rectal mucosal prolapse, and was followed by an high incidence of delayed healing of the perineal wound and dyspareunia. Sarles procedure achieved better control of mucosal prolapse but carried a higher complication rate compared to the others. The association of the perineal levatorplasty with an endorectal technique required significantly longer operative time, and led to a longer hospital stay and time to return to work. In conclusion, the investigated techniques showed different patterns of postoperative complications: bleeding after Sarles, dehiscence after Block, dyspareunia after perineoplasty and fatal gangrene after stapled, but non of them showed a clear superiority over the others in term of clinical or functional results 2 years after surgery.

Transverse coloplasty pouch after total mesorectal excision: functional assessment of evacuation.

PURPOSE: Colon pouch reconstruction after total mesorectal excision is functionally superior to straight colorectal/ anal anastomosis. In the long-term, stool evacuation difficulties could jeopardize the functional benefit. The transverse coloplasty pouch presents an alternative to the standard J-pouch. This study was designed to analyze functional outcome and defecography findings after total mesorectal excision and transverse coloplasty pouch reconstruction. METHODS: Thirty consecutive patients with cancer of the middle and lower third of the rectum underwent a total mesorectal excision and were examined in a prospective study. In all patients, reconstruction was performed with a transverse coloplasty pouch. Pouch and anastomosis were checked by Gastrografin enema postoperatively. Patients were examined within eight months by means of defecography, manometry, pouch volumetry, and a standardized continence questionnaire. RESULTS: Total mesorectal excision with transverse coloplasty pouch anastomosis was performed successfully in all patients. Symptomatic anastomotic leakage was observed in 2 of 30 patients and the radiologic leak rate was 4 of 30. All patients evacuated the pouch completely; none needed enemas or suppositories to facilitate defecation. Twenty-five of 27 patients had a maximum of three bowel movements per day, and all patients were continent for solid stools. Patients with abnormal findings on defecography proved more likely to have anal dysfunction. CONCLUSIONS: Transverse coloplasty pouch reconstruction after total mesorectal excision leads to good functional results and is not associated with stool evacuation problems. Urgency and incontinence correlate rather with impaired pelvic floor movement than with pouch size or anal sphincter tonus.
