Abstract
INTRODUCTION Chronic constipation is a common disorder with a reported prevalence ranging from 3% to 27% in the general population. Several management strategies, including diagnostic tests, empiric treatments, and specific treatments, have been developed. Our aim was to develop European guidelines for the clinical management of constipation. DESIGN After a thorough review of the literature by experts in relevant fields, including gastroenterologists, surgeons, general practitioners, radiologists, and experts in gastrointestinal motility testing from various European countries, a Delphi consensus process was used to produce statements and practical algorithms for the management of chronic constipation. KEY RESULTS Seventy-three final statements were agreed upon after the Delphi process. The level of evidence for most statements was low or very low. A high level of evidence was agreed only for anorectal manometry as a comprehensive evaluation of anorectal function and for treatment with osmotic laxatives, especially polyethylene glycol, the prokinetic drug prucalopride, secretagogues, such as linaclotide and lubiprostone and PAMORAs for the treatment of opioid-induced constipation. However, the level of agreement between the authors was good for most statements (80% or more of the authors). The greatest disagreement was related to the surgical management of constipation. CONCLUSIONS AND INFERENCES European guidelines on chronic constipation, with recommendations and algorithms, were developed by experts. Despite the high level of agreement between the different experts, the level of scientific evidence for most recommendations was low, highlighting the need for future research to increase the evidence and improve treatment outcomes in these patients.

Systematic review with meta-analysis: defecography should be a first-line diagnostic modality in patients with refractory constipation. Aliment Pharmacol Ther 2018; 48:1186-1201. [PMID: 30417419 DOI: 10.1111/apt.15039] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Revised: 07/16/2018] [Accepted: 10/08/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Defecography is considered the reference standard for the assessment of pelvic floor anatomy and function in patients with a refractory evacuation disorder. However, the overlap of radiologically significant findings seen in patients with chronic constipation (CC) and healthy volunteers is poorly defined. AIM To systematically review rates of structural and functional abnormalities diagnosed by barium defecography and/or magnetic resonance imaging defecography (MRID) in patients with symptoms of CC and in healthy volunteers. METHODS Electronic searches of major databases were performed without date restrictions. RESULTS From a total of 1760 records identified, 175 full-text articles were assessed for eligibility. 63 studies were included providing data on outcomes of 7519 barium defecographies and 668 MRIDs in patients with CC, and 225 barium defecographies and 50 MRIDs in healthy volunteers. Pathological high-grade (Oxford III and IV) intussuscepta and large (>4 cm) rectoceles were diagnosed in 23.7% (95% CI: 16.8-31.4) and 15.9% (10.4-22.2) of patients, respectively. Enterocele and perineal descent were observed in 16.8% (12.7-21.4) and 44.4% (36.2-52.7) of patients, respectively. Barium defecography detected more intussuscepta than MRID (OR: 1.52 [1.12-2.14]; P = 0.009]). Normative data for both barium defecography and MRID structural and functional parameters were limited, particularly for MRID (only one eligible study). CONCLUSIONS Pathological structural abnormalities, as well as functional abnormalities, are common in patients with chronic constipation. Since structural abnormalities cannot be evaluated using nonimaging test modalities (balloon expulsion and anorectal manometry), defecography should be considered the first-line diagnostic test if resources allow.

Abstract
Chronic constipation is a considerable problem because it significantly affects the quality of a patient's life. Constipation can be diagnosed at every age and is more frequent in women and among the elderly. In epidemiological studies, its incidence is estimated at 2-27% in the general population. Chronic constipation may be primary or secondary. However, primary constipation (functional or idiopathic) can be classified into normal transit constipation, slow transit constipation, and pelvic outlet obstruction. In this review we make an attempt to present the current pathophysiological aspects and new therapeutic options for chronic idiopathic constipation, particularly highlighting the value of patient assessment for accurate diagnosis of the cause of the problem, thus helping in the choice of appropriate treatment.

Abstract
BACKGROUND AND AIMS We report our experience of concomitant laparoscopic treatment for enterocele and stapled transanal rectal resection (STARR) for rectocele and/or rectal prolapse in patients with complex obstructed defecation syndrome (ODS). PATIENTS AND METHODS From June 2005 to June 2007, we submitted 20 patients with ODS due to rectal prolapse and/or rectocele, combined with stable enterocele, to STARR and laparoscopic correction of the enterocele. Preoperative assessment included symptom evaluation with standardized questionnaires, clinical examination, colonoscopy, proctoscopy, anal sphincter ultrasonography, video-defecography with synchronous opacification of the ileal loops in all patients and colpography in female patients, and anorectal manometry. Follow-up was performed in the first, third, sixth, 12th, and 24th month after surgery. RESULTS Eighteen (90%) patients were submitted to both procedures, simultaneously. One patient, previously submitted to STARR, underwent laparoscopic treatment of the enterocele. Postoperative complications occurred in two (10%) patients: one case of postoperative rectal bleeding and one case of retropneumoperitoneum. Median (range) preoperative and postoperative Altomare's obstructed defecation score was ten (6-14) and two (0-14), respectively (p<0.001). Median (range) preoperative and postoperative quality of life score was 79 (39-109) and 109 (50-126), respectively (p<0.001). No symptom related to ODS was detected at 6-month follow-up (19 patients) and at 24-month follow-up (19 patients). CONCLUSION The combination of STARR and laparoscopy provides a safe and effective method to treat ODS caused by rectal internal prolapse and/or rectocele combined with enterocele.

Abstract
Constipation is a subjective symptom of various pathological conditions. Incidence of constipation fluctuates from 2 to 30% in the general population. Approximately 50% of constipated patients referred to tertiary care centers have obstructed defecation constipation. Constipation of obstructed defecation may be due to mechanical causes or functional disorders of the anorectal region. Mechanical causes are related to morphological abnormalities of the anorectum (megarectum, rectal prolapse, rectocele, enterocele, neoplasms, stenosis). Functional disorders are associated with neurological disorders and dysfunction of the pelvic floor muscles or anorectal muscles (anismus, descending perineum syndrome, Hirschsprung's disease). However, this type of constipation should be differentiated by colonic slow transit constipation which, if coexists, should be managed to a second time. Assessment of patients with severe constipation includes a good history, physical examination and specialized investigations (colonic transit time, anorectal manometry, rectal balloon expulsion test, defecography, electromyography), which contribute to the diagnosis and the differential diagnosis of the cause of the obstructed defecation. Thereby, constipated patients can be given appropriate treatment for their problem, which may be conservative (bulk agents, high-fiber diet or laxatives), biofeedback training or surgery.

Abstract
PURPOSE This study was undertaken to analyze whether intra-anal ultrasound examination, anorectal physiologic evaluation, and histopathologic examination in patients with chronic idiopathic anal pain presented any common features and whether the results of different treatment modalities correlated with these findings. METHODS Eighteen patients who met the criteria for chronic idiopathic anal pain were studied. All had an intra-anal ultrasound examination and a complete anorectal physiologic evaluation. In a selected group of patients, ultrasound-guided biopsy samples were taken from pathological areas in the internal and external sphincter. Treatment consisted of analgesics only in four patients, 0.2 percent nitroglycerin ointment in four, and ultrasound injection of botulin (botulinum toxin, Botox) into the intersphincteric space in nine. Two patients, including one who was previously treated with botulin, ultimately had a colostomy. RESULTS Four patients were managed satisfactorily on analgesic treatment under the guidance of the hospital's pain clinic. Nitroglycerin ointment resulted in temporary pain relief in one of four patients. Injection of botulin resulted in a permanent improvement in four patients, a temporary improvement in one patient, and no effect in four patients. Two patients had a colostomy, resulting in complete pain relief. The effect or lack of effect of nitroglycerin ointment and botulin was not related to changes in anal pressure. CONCLUSION Chronic idiopathic anal pain is a condition of unknown origin for which no proven therapy exists. As in other syndromes based on muscular dystonia, some patients may benefit from injection of botulin.

Abstract
PURPOSE Anorectal angle and perineal descent can be measured either by drawing a line defined by the impression of the puborectalis muscle and the tangential of the posterior rectal wall (Method A) or by drawing a straight line at the level of the posterior rectal wall parallel to the central longitudinal axis of the rectum (Method B). The aim of this study was to assess the reproducibility of measuring anorectal angle and perineal descent by two different methods according to intraobserver and interobserver measurement and to evaluate which method yields more consistent results. METHODS Five physicians who have had an average of 1.3 years (range, 6 months to 1.5 years) experience in defecographic measurement drew both lines on 63 randomly selected defecographic films and measured anorectal angle and perineal descent by the two methods. The defecographic parameters were measured twice by each observer during a three-week interval. To avoid potential bias, one physician who did not participate in either measurement of perineal descent or anorectal angle performed all data collection. Intraobserver and interobserver agreement was quantified using Shrout and Fleiss intraclass correlation coefficients. RESULTS The mean and range of intraclass correlation coefficients for intraobserver agreement of measuring anorectal angle and perineal descent by Method A were 0.71 (0.6-0.78) and 0.89 (0.74-0.97), respectively, whereas with Method B the coefficients were 0.81 (0.73-0.89) and 0.93 (0.89-0.99), respectively. Regarding the interobserver agreement of the five observers, the mean coefficients for measurement of both anorectal angle and perineal descent by both methods showed similar agreement levels (0.88 and 0.98 by Method A and 0.89 and 0.97 by Method B). The mean (+/- standard deviation) values of anorectal angle and perineal descent found by Method B were significantly larger than those found by Method A (103.3 degrees +/- 19.6 and 6.56+/-3.20 cm and 91.1 degrees +/- 25.6 and 5.64+/-3.42 cm, respectively; P<0.001). CONCLUSION Intraobserver and interobserver intraclass correlation coefficients of anorectal angle and perineal descent, which were measured by both methods, were more than 0.60, indicating that both methods are reliable and consistent for measurement of anorectal angle and perineal descent. However, centers should consistently use the same line for measurement of anorectal angle and perineal descent because of the statistically significant differences between the two methods and the possibility of inconsistent results.

Abstract
PURPOSE This study was designed to evaluate symptoms and clinical findings in a prospective series of patients with chronic constipation. METHODS A total of 155 consecutive patients with intractable constipation underwent detailed symptom registration, anorectal manometry, electromyography, colonic transit time measurement, and defecography. RESULTS All investigations were completed by 134 patients (112 females) with a median age of 52 (range, 17-79) years. Whole-gut transit time was delayed in 55 patients (41 percent), pelvic floor dysfunction was diagnosed in 59 patients (44 percent), but in 35 percent of patients both transit time and pelvic floor function were found to be normal. Three symptoms were shown to have an independent value for the diagnosis of slow-transit constipation. Patients with slow transit more often reported two or fewer stools per week (84 vs. 46 percent), laxative dependence (87 vs. 44 percent), and a history of constipation since childhood (58 vs. 22 percent) than did those with normal transit. Pelvic floor dysfunction was associated with a higher prevalence of backache (53 vs. 33 percent) and a lower prevalence of normal stool frequency (19 vs. 36 percent), heartburn (12 vs. 27 percent), and a history of anorectal surgery (7 vs. 21 percent) compared with those with normal pelvic floor function. All four symptoms retained an independent value in the logistic regression analysis for pelvic floor dysfunction. Two symptoms characterized the group with normal transit and normal pelvic floor function: normal stool frequency and alternating diarrhea and constipation. CONCLUSIONS Symptoms are good predictors of transit time but poorer predictors of pelvic floor function in patients with constipation.

Abstract
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.

Abstract
PURPOSE This study was undertaken to assess the effect of biofeedback therapy in patients with constipation and paradoxical puborectalis contraction and to compare two different feedback modes. METHODS Twenty-six patients were randomly allocated to either of two feedback modes: anal pressure using a manometry probe or anal sphincter electromyography (EMG) using surface electrodes. RESULTS Six patients were unable to complete their training; ten patients were retrained using anal manometry and ten patients using EMG. The paradoxical puborectalis contraction disappeared after retraining with manometry feedback in eight of ten patients and with EMG feedback in ten of ten patients. A significant improvement in both bowel function and abdominal symptoms was found after training and a continued improvement at follow-up six months later. Six patients in the manometry group and nine in the EMG group experienced an overall improvement in symptoms. The two feedback methods did not differ in terms of efficacy. CONCLUSIONS Our results suggest that biofeedback, using either manometry or EMG, is effective in improving symptoms and anorectal function caused by paradoxical puborectalis contraction.

Abstract
PURPOSE The aim of this study was to evaluate the role of defecography in predicting clinical outcome of rectocele repair. METHODS Between January 1988 and July 1994, 74 consecutive patients (median age, 54 (range, 35-81) years) with a rectocele and symptoms of obstructed defecation were studied prospectively. After preoperative evaluation by a standardized questionnaire, physical examination, and defecography, a combined transvaginal/transanal rectocele repair was performed. At follow-up, all patients had defecography. Long-term results were qualified by an independent observer after a median follow-up of 58 (range, 14-89) months as "excellent," "good," or "poor." RESULTS Rectocele repair was considered excellent in 37 patients and good in 13 patients. Defecography six months after surgery did not show persistent or recurrent rectocele in any of the patients. Size of the rectocele, barium-trapping in the rectocele, internal intussusception, rectal evacuation, and perineal descent did not appear to influence clinical outcome. Radiologic evidence of anismus did not correlate with long-term results of rectocele repair. CONCLUSIONS Combined transanal/transvaginal repair of rectocele is an efficient therapy in patients with obstructed defecation. Various defecographic parameters (size of rectocele, internal intussusception, rectal evacuation, perineal descent, radiologic signs of anismus) do not appear to influence clinical outcome of surgery. The main value of defecography is the objective demonstration of rectocele and any associated abnormalities such as an enterocele preoperatively and again in objective assessment of the postoperative results.

Abstract
We reviewed the medical records and defecograms in 55 consecutive patients to determine the impact of results of defecography on clinical management. Main indication for defecography was constipation, present in 40 (73%) of 55 patients. In the remaining 15 patients, indications included obstructed defecation (5), incontinence (5), and miscellaneous symptoms (5). Defecography evaluated pelvic floor motion by assessing changes in the anorectal angle (ARA) and anorectal junction (ARJ) during various maneuvers, extent of evacuation, and structural abnormalities. Patients were grouped based on results of defecography as being normal (26) or abnormal (29). Comparison of measurements of the ARA and ARJ with various maneuvers showed no significant differences between the two groups. Clinical impact was determined by analyzing therapy done following defecography and subsequent patient response. In the normal group, 15 patients were managed medically, seven surgically, and four lost to follow-up. Clinical improvement occurred in 13 (59%) of 22 patients, with similar results between medical (60%) and surgical (57%) therapy. In the abnormal group, 16 had medical management, seven surgical therapy, and six lost to follow-up. Clinical improvement occurred in 13 (57%) of 23 patients but surgical therapy showed more improvement. In conclusion, most standard measurements of the ARA and ARJ were of no value in determining abnormality. Results of defecography did not alter selection of medical or surgical therapy, and had little impact on patient response to therapy.

Abstract
PURPOSE Conventional assessment of anorectal function with defecating videoproctography is semiquantitative and the high radiation exposure precludes prolonged or repeated testing. The aim of this study was to develop a dynamic scintigraphic method of assessing anorectal function. METHODS Fourteen patients with fecal incontinence, 18 patients with chronic constipation, and 8 control subjects were assessed by scintigraphic defecography. This involves introduction of a technetium-99m-radiolabeled artificial stool into the rectum of the subject and acquisition of gamma camera images during evacuation. RESULTS Mean evacuation rate was 2.8 percent/second in incontinent patients and 0.9 percent/second in constipated patients (P < 0.001). The mean anorectal angles were 136 degrees and 133 degrees, respectively. There were 18 cases of pelvic floor descent and 6 rectoceles. Scintigraphic defecography provides quantitative information on rectal evacuation. Anorectal angle and pelvic floor movement can be examined. The radiation dose to pelvic organs is significantly less than with videoproctography. CONCLUSION We believe that scintigraphic defecography is the investigation of choice for objective and dynamic assessment of anorectal function.

Abstract
Patients with obstructed defecation show no consistent abnormalities when assessed by standard anorectal physiologic methods. With a recently developed technique for dynamic anal manometry, we studied 13 female patients with obstructed defecation and 20 healthy volunteers. Seven parameters of anal function were measured. There were no differences between the median values for the two groups. Seven patients (54 percent; 95 percent confidence limits, 25-81 percent) had anal compliance below the normal range, either during opening or closing of the sphincter at rest (five patients), during squeeze (one patient), or both (one patient). Opening and closing pressures of the sphincter at rest, maximal closing pressure during squeeze, and anal hysteresis were normal. Standard anal manometry did not show any differences between patients and controls. Rectal compliance was lower in patients with obstructed defecation, median difference 5 ml/cm H2O (95 percent confidence limits, 1-9 ml/cm H2O). In conclusion, the more detailed method of dynamic anal manometry shows that some patients with obstructed defecation have a less compliant anal sphincter and a less compliant rectum, but in many patients no abnormal findings can be made.

Abstract
Of 71 patients with paradoxical sphincter reaction, 54 had symptoms of constipation or outlet obstruction and 17 were incontinent. The patients were investigated with defecography, colon transit time, anorectal manometry and electromyography. Ninety-six percent of the patients had additional changes in anorectal anatomy and physiology; 70% of the patients had abnormal defecography and 42% had delayed colon transit time. Decreased maximal anal pressure (MAP) and maximal squeeze pressure (MSP), indicating impaired function of the anal sphincters might be one reason for incontinence in patients with paradoxical sphincter reaction. The paradoxical reaction occurred in the puborectalis muscle and in three tested sites in the external sphincter. It is sufficient to record the EMG activity in one muscle and at one point to diagnose a paradoxical sphincter reaction. The absence of a normal closing reflex on electromyography is evidence for a paradoxical sphincter reaction. Denervation was more pronounced in the external sphincter than in the puborectalis muscle. The right pudendal nerve was subjected to damage more often than the left nerve.

Abstract
A prospective study was undertaken to compare two different methods of measuring the anorectal angle (ARA), balloon proctography (BP) and cinedefecography (CD), as well as to evaluate the reproducibility of this measurement using each technique. One hundred four consecutive patients (75 women and 29 men) with constipation (63 patients), fecal incontinence (25 patients), or rectal pain (16 patients) underwent both BP and CD. The ARA was measured by taking lateral radiographs of the pelvis during rest (R), squeeze (S), and push (P). The same interpretation process was performed 2 to 12 months later by the same observer, blinded as to diagnosis and initial measurements. There were highly significant differences in each measurement category, R (P less than 0.0001), S (P less than 0.0001), and P (P less than 0.0004) between BP and CD. However, the correlation between the first and second measurements was excellent (P less than 0.0001). BP was consistently more difficult to interpret because of balloon configuration. Although BP and CD have poor correlation with each other, each examination can be reliably interpreted. CD appears to be a superior examination because of the added ability to delineate rectoceles, intussusceptions, and other structural defects.

Abstract
To evaluate the results and clinical impact of defecography in patients with anorectal disorders, 100 results of defecographic examinations from 92 patients were reviewed. The defecographic results were screened for the anorectal angle, defined both at rest and during straining, perineal descent, and abnormalities of the rectal configuration during straining. Anal manometry, saline infusion test, rectal capacity measurement, and anal electromyography (EMG) were also performed. There was a significant difference (P less than 0.001) both at rest (22 degrees) and during straining (12 degrees) between the two anorectal angle measurements. Incontinent patients had a larger anorectal angle, both at rest and during straining, than continent patients (P less than 0.04), but with a large overlap. The anorectal angle was not influenced by gender or age. An abnormal rectal configuration was found in 62 defecographic examinations. From the 8 patients with rectopexy performed for a large rectocele or intussusception, incontinent patients with an intussusception had the best results. In four patients, anal EMG showed an increased activity of the external sphincter during straining. Two of these four patients had abnormal defecograhic results. No correlations were found between anorectal angle and the other function tests. In conclusion, the anorectal angle lacks clinical relevance. In patients with defecation problems, defecography may be indicated whenever other investigations (physical examination, anal manometry, anal EMG) have excluded local pathology or a spastic pelvic floor syndrome. In these situations, defecography could detect an intussusception, which could easily be treated with rectopexy.

Abstract
Perineal descent was studied by defaecography with the patients in the sitting position in 55 healthy volunteers, 21 women with idiopathic faecal incontinence and 8 women with obstructed defaecation. This technique provides data necessary for the evaluation of defaecation disorders, i.e. morphological changes during defaecation as well as the dynamics of the pelvic floor. It was found that the pelvic floor position during rest and during straining is almost the same in women with incontinence and in women with obstructed defaecation. Furthermore patients with normal position of the pelvic floor during rest may exhibit considerable descent during straining while patients with abnormal position of the perineum during rest may show normal descent during straining. This observation may indicate that the first sign of abnormal function may be an increased descent during straining, only later following by descent during rest. The importance of establishing control data is emphasized since differences in defaecographic techniques between different centres may render comparison difficult.
