RESUMEN
AIM: Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA) is the most frequently performed operation for intractable ulcerative colitis (UC) and for many patients with familial adenomatous polyposis (FAP). It can be complicated by a functional evacuation difficulty, which is not well understood. We aimed to evaluate the role of defaecating pouchography in an attempt to assess the mechanism of evacuation difficulty in pouch patients. METHOD: All RPC patients who had had a defaecating pouchogram for evacuation difficulty at one hospital between 2006 and 2014 were retrospectively reviewed. The findings and features were correlated with the symptoms. Demographic, clinical and radiological variables were analysed. RESULTS: Eighty-seven [55 (63%) female] patients aged 47.6 ± 12.5 years (mean standard ± SD) were identified. Thirty-five had a mechanical outlet obstruction and 52 had no identified mechanical cause to explain the evacuation difficulty. The mean age of these 52 [33 (63%) female] patients was 48.2 ± 13 years. Of these 52 patients, significantly more used anti-diarrhoeal medication (P = 0.029), complained of a high frequency of defaecation (P = 0.005), experienced a longer time to the initiation of defaecation (P = 0.049) and underwent pouchoscopy (P = 0.003). Biofeedback appeared to improve the symptoms in 7 of 16 patients with a nonmechanical defaecatory difficulty. The most common findings on defaecating pouchography included residual barium of more than 33% after an attempted evacuation (46%, n = 24), slow evacuation (35%, n = 18) and mucosal irregularity (33%, n = 17). Correlation between radiological features and symptoms showed a statistically significant relationship between straining, anal pain, incontinence and urgency with patterns of anismus or pelvic floor descent or weakness seen on the defaecating pouchogram. Symptoms of incomplete evacuation, difficulty in the initiation of defaecation, high defaecatory frequency and abdominal pain were not correlated with the radiological features of the pouchogram. CONCLUSION: Defaecating pouchography may be useful for identifying anismus and pelvic floor disorders in pouch patients who have symptoms of straining, anal pain or incontinence. In patients with a high frequency of defaecation and abdominal pain it does not provide clinically meaningful information. Patients who complain of straining, incontinence, anal pain or urgency and have anismus or pelvic floor disorders may benefit from behavioural therapy.

BACKGROUND AND AIM: Appropriate treatment of perianal fistulas in Crohn's disease (CD) involves accurate anatomic evaluation. EUS is an accepted imaging method for this purpose. The aim of the current study was to evaluate the clinical and endosonographic characteristics of perianal fistula in CD and to assess its impact on therapy. METHODS: All CD patients referred to the Sheba medical center from June 2004 to August 2008 for EUS examination of perianal fistulas were included. Perianal fistulas were diagnosed based on a clinical examination revealing at least one perianal cutaneous orifice. Demographic, clinical and therapeutic data was obtained. EUS was performed using an ultrasound scanner producing a 360° cross sectional image of the anal sphincters. RESULTS: Fifty six patients were included in the study. Four patients were excluded from the final analysis: 3 because no fistula could be detected by EUS, and one due to inability to tolerate the examination. The mean CD duration was 10±9.16 years (range 1-37). Mean perianal disease duration was 5.3±6.5 (range 1-29) years. 27 patients had perianal involvement at presentation. Among the fistulas diagnosed, 13 were simple (25%) and 39 were (75%) complex. No correlation was found between CD duration or location, patients' age and gender or fistula location with fistula type or complexity. EUS results influenced patient management in 86% of the patients. CONCLUSIONS: CD-associated perianal fistulas are mainly complex. EUS is a well tolerated and informative imaging modality, with significant impact on treatment.

INTRODUCTION: Proctalgia fugax (PF) is a benign, self-limiting disease characterized by episodes of intense anorectal pain at frequent intervals in the absence of organic proctological disease. Even though PF was described more than a century ago, its etiology remains unclear. Currently there is no information available. Few papers quoting many ways of management have been published. The aim of this study was to investigate patients complaining of this condition and to treat them with sequential therapy. PATIENTS AND METHODS: We devised a descriptive, prospective study of patients complaining of acute perianal pain--duration less than 30 minutes--without organic disease or previous perianal surgery since 1996 to 2002 in our Department. We treated these patients using a three-step treatment (1: information, hip bath, benzodiazepines; 2: sublingual nifedipine 10 mg, or topic 0.1% nitroglycerin on demand; 3: internal anal sphincterotomy if hypertrophy of the internal anal sphincter was demonstrated by anal ultrasonography and no improvement was confirmed with the previous steps of treatment). We defined remarkable improvement as a decrease in the number of episodes by half or in pain intensity by 50%. RESULTS: Fifteen patients with an average follow-up of 4 years. Anal endosonography confirmed a grossly thickened internal anal sphincter (IAS) in 5 cases. After the first step of treatment 7 patients improved and 1 patient was cured; after the second step of treatment 3 patients improved and 1 was cured; the third step was applied to 3 patients with a thickened IAS; 1 patient improved and 1 patient was cured. CONCLUSION: A total resolution of PF is not always possible, but we may improve symptoms and their frequency. Almost 50% of patients in our series improved with the first step of treatment; 30% of our patients had IAS hypertrophy. Anal endosonography can help in the diagnosis of organic diseases or IAS hypertrophy, for which we can perform an internal anal sphincter myectomy.

PURPOSE: This study was designed to determine whether patients with fecal incontinence and endoanal ultrasound evidence of anal sphincter disruption may be successfully treated by sacral nerve stimulation. METHODS: Five consecutive females with incontinence to solids and endoanal ultrasound evidence of anal sphincter disruption were treated by a two-week trial of sacral nerve stimulation. If successful, patients then proceeded to permanent sacral nerve stimulation implantation. RESULTS: Five patients, aged 34 to 56 years, were treated by temporary sacral nerve stimulation. Four had symptoms starting after childbirth. Two had previously had an anterior sphincter repair. After a two-week trial, three females reported full continence and an improvement in all aspects of their Rockwood fecal incontinence quality of life scores. These three females underwent permanent sacral nerve stimulation implantation. The remaining two patients reported no improvement and underwent dynamic graciloplasty or end colostomy respectively. CONCLUSIONS: Sacral nerve stimulation may successfully restore bowel continence in some patients with endoanal ultrasound evidence of a defect in their external anal sphincter.

AIMS: To evaluate the impact of adjuvant biofeedback following sphincter surgery. METHODS: Thirty-eight patients were randomized into sphincter repair or sphincter repair plus biofeedback groups. Outcome measures included a symptom questionnaire, patient's rating of satisfaction with continence function and improvement, change in continence score, quality of life and anorectal physiology. Endoanal ultrasonography was also performed pre- and post-operatively. RESULTS: Immediately following surgery, there was no statistically significant difference in any of the functional or physiological variables between the groups. Continence and patient satisfaction scores improved with a mean difference of -0.48 (95% CI: -3.30-2.33, P = 0.73) and 1.03 (95% CI: -1.40-3.46, P = 0.39), respectively. Only the difference in embarrassment scores reached statistical significance (mean) 0.56 (95% CI: 0.12-0.99, P = 0.014). Resting and squeeze pressures also improved. Thirteen of 14 in the biofeedback and 11 of 17 (control) reported symptomatic improvement. In the biofeedback group, although not statistically significant continence and satisfaction scores improved and were sustained over time. In the control group, continence and satisfaction scores changed little between 3 and 12 months (P = NS). Quality of life measures improved within the biofeedback group but there was no statistical difference between the groups. CONCLUSION: Following surgery continence function improves in all patients but adjuvant biofeedback therapy improves quality of life and maintains symptomatic improvement over time.

We report a rare case of perianal endometriosis, diagnosed in a 39-year-old woman who presented with a several-day history of a painful mass in the perineum. Perianal examination showed redness and swelling in the right anterior direction. A soft tumor was palpated, but there was no evidence of an episiotomy scar, or of fistula orifices. An anal endosonography in the right anterior direction revealed a sharply defined lesion, 17 x 14 mm in diameter, with high echoic enhancement at its center. The lesion was located along the edge of the external anal sphincter but did not involve it. Based on these endosonographic findings, the tumor was not considered to be an abscess or fistula. We detected its location, and judged it possible to enucleate the tumor under local anesthesia without injuring the anal sphincter. The operation was performed uneventfully and a histological diagnosis of endometriosis was confirmed. Using anal endosonography, we were able to determine the exact anatomic relationship of the lesion in the internal and external sphincter, which substantially influenced the diagnosis and operative procedures.

OBJECTIVE: We aimed to determine the positive predictive value of impaired evacuation during evacuation proctography for the subsequent diagnosis of anismus. SUBJECTS AND METHODS: Thirty-one adults with signs of impaired evacuation (defined as the inability to evacuate two thirds of a 120 mL contrast enema within 30 sec) during evacuation proctography underwent subsequent anorectal physiologic testing for anismus. A physiologic diagnosis of anismus was based on a typical clinical history of the condition combined with impaired rectal balloon expulsion or abnormal surface electromyogram. RESULTS: Twenty-eight (90%) of the 31 patients with impaired proctographic evacuation were found to have anismus at subsequent physiologic testing. Among the 28 were all 10 patients who evacuated no contrast medium and all 11 patients with inadequate pelvic floor descent, giving evacuation proctography a positive predictive value of 90% for the diagnosis of anismus. A prominent puborectal impression was seen in only three subjects during proctography, one of whom subsequently showed no physiologic sign of anismus. CONCLUSION: Impaired evacuation during evacuation proctography is highly predictive for diagnosis of anismus.

REPORT STUDY: Defaecography reports from 2816 patients were evaluated. Twenty-three percent of the investigations were considered normal, 31% showed rectal intussusception, 13% rectal prolapse, 27% rectocele, and 19% enterocele. A standardised protocol is suggested to ensure a complete evaluation of defaecography. One hundred and ten reports were unclear and reviewed. The unclear reports usually concerned an unexplained widening of the rectovaginal space, and gave incitement to further studies. TECHNIQUE STUDY: Twelve patients with an unexplained widening of the rectovaginal space at defaecography were investigated using defaecography and peritoneography simultaneously, by us named defaeco-peritoneography. All investigations were carried out without complications. Defaeco-peritoneography proved the unexplained widening to be an extension of the pouch of Douglas, a peritoneocele. UNEXPLAINED WIDENING STUDY: Twenty-two patients with unexplained widening of the rectovaginal space noted at defaecography were studied using defaeco-peritoneography. The outline and movements of the peritoneum in the pelvic cavity could be visualised during the dynamic act of defaecation. The unexplained widening of the rectovaginal space was caused completely by a peritoneocele in 14 patients, partially in 6 patients and 2 remained unexplained. However, only 9 out of 22 widenings were peritoneoceles with an enterocele. Just 11 peritoneoceles only contained fluid. Three types of peritoneocele were demonstrated: vaginal, septal, and rectal, with or without enterocele. Combinations of these were also found. RECTAL INTUSSUSCEPTION STUDY: Fifty-seven patients with defaecation disorders were examined using defaeco-peritoneography. Twenty-three patients had rectal intussusception and 7 patients had a rectal prolapse. All these patients had a rectal peritoneocele in the serosal ring-pocket of the rectal intussusception or in the rectal prolapse. Twenty-seven patients had neither rectal intussusception nor rectal prolapse and none of these patients had a rectal peritoneocele. DAILY LIFE STUDY: Twenty-six female patients showing peritoneocele without a contrast-filled rectum at start at defaeco-peritoneography were investigated; 13 of them had enteroceles. Spot radiographs before and after filling the rectum with contrast medium were compared. The peritoneocele disappeared completely in 19 of the patients and was reduced in size in the remaining 7, and the enterocele disappeared completely when the rectum was distended. Defaeco-peritoneography should therefore include a radiograph before the rectum is filled, as it shows the habitual (daily life) anatomy and can disclose pathology as peritoneocele and enterocele. TRANSFORMATION STUDY: Forty-six patients with peritoneocele at defaeco-peritoneography were studied at three different stages during rectal evacuation. At start with contrast-filled rectum, 14 patients had a peritoneocele, and 32 were regarded as normal. At maximum straining, all patients had a peritoneocele and 20 of these were still present after rectal evacuation. The peritoneoceles were largest at straining and rectal types were most common. No enterocele was seen at start. At maximum straining, 21 patients developed an enterocele.

Although the anorectal junction is easily accessible, this area may be difficult to evaluate both radiologically and endoscopically because it is relatively collapsed. This pictorial essay illustrates the barium enema radiographic findings and reviews the radiologic and endoscopic pitfalls in the diagnosis of lesions of the anorectal junction.

The authors report two cases of colonic intussusception in the adult protruding from the anus--or colon-anal intussusception--, not due to a tumor. The first case was a chronic ileo-caeco-colique intussusception, the second case was an acute colo-rectal intussusception. Colo-anal intussusceptions are very rare: less than twenty cases have been described since 1925 in adults. The absence of a tumor origin in our cases represents a special feature, as only three other similar cases have been described. The surgical treatment in both cases was primary colonic resection without colostomy. The surgical treatment of the first case was subtotal colectomy with ileo-rectal anastomosis. The second case was primarily reduced by barium enema which allowed optimal secondary surgical resection of a prepared colon.

This retrospective study examines the value of an air contrast barium enema examination in detecting proximal neoplasia in the patient presenting with benign anorectal disease as determined by history, physical examination, rigid, and flexible sigmoidoscopy. In 428 of these patients, the roentgenographic studies showed proximal colonic cancer or polyps in less than 1 percent of patients reviewed. In addition, a review of 402 patients with known colon and rectal cancer were surveyed using the same criteria for diagnosis, and less than 1 percent were misinterpreted as having benign anorectal disease.

A rare example of xanthogranulomatous inflammatory mass and abscess of a Mullerian duct remnant involving the anorectal area is reported. A barium enema showed a bilobed precoccygeal mass of moderate size involving the posterior aspect of the distal rectum. Computed tomography (CT) showed two nonfatty, round masses, one of which contained a small central cystic area. The other mass had a homogeneous appearance and was believed to be in the wall of the rectum. The pathologic specimen showed organizing abscesses and a chronic xanthogranulomatous inflammation in tissue compatible with urogenital tissue, presumably a Mullerian duct remnant. This is the first documented report of anorectal xanthogranulomatous abscess in a Mullerian duct remnant with radiologic findings and histopathologic correlation. Though rare, this lesion should be considered in the differential diagnosis of extrinsic and intramural rectal masses seen on barium enema and CT examinations.

Defecography is a technique of examining the rectum and anal canal in which the patient is studied while sitting down rather than recumbent and recordings are obtained both at rest and during straining. The authors describe their findings in 83 patients with dyschezia. Defecation was normal in 28 patients. Prolapse of the anal mucosa was seen in 13 patients and internal procidentia in 23, 12 of whom also had intussusception manifested as rectal prolapse. A deep rectogenital fossa associated with an enterocele was seen in 16 patients; 13 had a proctocele, while fecal retention was seen in 5. Descent of the pelvic floor and changes in the angle between the rectum and anal canal were assessed. The authors recommend defecography as a more physiological means of assessing rectal dysfunction.
