ABSTRACT

BACKGROUND: The aim of this study was to evaluate the impact of the transanal repair of rectocele and rectal mucosectomy with a single circular stapler (TRREMS) on the treatment of obstructed defecation due to rectocele and to identify the predictive factors for unsuccessful results. METHODS: Consecutive patients with obstructed defecation symptoms (ODS) associated with rectocele who had the TRREMS procedure were included. Each patient was assessed by echodefecography, manometry, and colonic transit time as well as the Cleveland Clinic constipation score (CCS) before therapy and at follow-up after 6 months. Reduction in the CCS score was calculated as a ratio. Factors correlated with a decrease in the CCS were analyzed in a univariate analysis. RESULTS: A total of 81 patients were included. Nineteen patients had postoperative complications that were not severe: 7 (8.6%) had tenesmus, 6 (7.4%) stenosis (4 treated with digital dilatation and 2 with endoscopic stricturectomy), 4 (4.9%) residual mucosal prolapse treated with rubber band ligation, 1 (1.2%) early bleeding, and 1(1.2%) thrombosis. Seventy-nine (97.5%) patients had a significant clinical response with significant reduction of the CCS constipation score from median 13 (range 17-10) to 4 (range, 8-2) (p = 0.0001); only 2 patients (2.5%) had an unsatisfactory response, complaining of straining and vaginal digitation during the evacuatory effort. Patients with anismus previously treated with biofeedback had a lower reduction ratio of the CCS score compared with patients without anismus (61.2 ± 2.8% versus 70.9% ± 1.5, p = 0.0006). There were no significant differences in the reduction of the CCS according to age, parity, type of delivery, previous hysterectomy, post-menopausal status, rectal mucosal prolapse and/or associated rectal intussusception, grade of rectocele and presence of complications. CONCLUSIONS: The TRREMS procedure significantly improved evacuation disorders in this study. Appropriate selection of patients is key for the success of this approach. Anismus even if previously treated with biofeedback, was the main predictive factor of unsuccessful treatment.

ABSTRACT

BACKGROUND: Vaginal delivery is the most frequent cause of direct anal sphincter trauma as well as pelvic floor muscle defects in women with corresponding signs and symptoms. The aim of the present study was to identify anatomical and functional abnormalities of the anal canal and pelvic floor in women who had had a vaginal delivery and determine the relationship between such abnormalities and the symptoms and severity of fecal incontinence (FI). METHODS: Consecutive female patients with symptoms of fecal and/or urinary incontinence were recruited through the colorectal and gynecological outpatient clinics at two large university hospitals and were eligible if they had had at a vaginal delivery. All women were assessed for symptoms FI by means of the Cleveland Clinic Florida Incontinence Scale (CCFIS) and for urinary incontinence symptoms, including the presence of complaints of any involuntary leakage of urine, leakage on exertion, sneezing, or coughing, and/or leaking or losing urine associated with an urge to urinate. All women underwent anorectal and endovaginal three-dimensional ultrasonography and anal manometry. The extent of the anal sphincter and PVM defects identified by ultrasound was scored from 1 to 6 based on the longitudinal involvement of the external and internal anal sphincter, the radial angle of the anterior external anal sphincter defect and the longitudinal involvement of the PVM. RESULTS: There were 130 women and 89 (68%) had at least one defect of the anal sphincter or the pubovisceral muscle or both (42/32% had a pubovisceral muscle defect with or without sphincter defects, 47/36% women had an intact pubovisceral muscle but sphincter defect); and 41 (32%) had intact anal sphincter and pubovisceral muscles. The mean levator hiatus area at rest in women with anal sphincter and/or pubovisceral muscle defects was 18 (± 4 SD) which was significantly greater than in women with no defects (16 ± 3 SD; p = 0.01). Women with PVM defects had significantly higher ultrasound scores (median ultrasound score = 4/range 1-10 vs Intact = 2/range 2-5), indicating more extensive defects (p = 0.001). Bivariate analysis revealed a positive association (p < 0.05) between increasing FI symptom severity (CCFIS score) and women with PVM defects (ρ = 0.6913). Within the group of women with defects mean maximum anal squeeze pressure was significantly lower in women with PVM defect (mean 73 ± 34 SD mmHg vs mean 93 ± 38 SD; p = 0.04). Women with PVM defects had significantly higher median CCFIS scores (median score, 7/range 0-16) compared to women with intact PVM (4/range 0-10) (p < 0.001). There was a significant positive correlation between the CCFIS and ultrasound scores (ρ = 0.625; p < 0.001). Bivariate analysis revealed a negative correlations between the CCFIS score and the lengths of the anterior EAS (ρ = - 0.5621, p < 0.001), IAS (ρ = - 0.40, p < 0.001) and the area of the levator hiatus (ρ = 0.5211, p = 0.001). However, no significant correlations were observed between CCFIS scores and the gap measurement (ρ = 0.101; p = 0.253) or the resting (ρ = - 0.08, p = 0.54) or squeeze pressure (ρ = - 0.12; p = 0.34) values on anal manometry. The variables associated with worsening FI symptom severity (CCFIS score) that remained significant in multiple linear regression included the shorter lengths of the anterior EAS and/or the lengths of the anterior IAS and increased area of the levator hiatus. CONCLUSIONS: The study data demonstrate that half of the women had combined defects of PVM and sphincter. There were correlations between anatomical abnormalities including the anal sphincter and/or pubovisceral muscle defects with decrease in the anal pressures and increased severity of FI.

ABSTRACT

BACKGROUND: The aim of this study was to evaluate the role of dynamic translabial ultrasound (TLUS) in the assessment of pelvic floor dysfunction and compare the results with echodefecography (EDF) combined with the endovaginal approach. METHODS: Consecutive female patients with pelvic floor dysfunction were eligible. Each patient was assessed with EDF combined with the endovaginal approach and TLUS. The diagnostic accuracy of the TLUS was evaluated using the results of EDF as the standard for comparison. RESULTS: A total of 42 women were included. Four sphincter defects were identified with both techniques, and EDF clearly showed if the defect was partial or total and additionally identified the pubovisceral muscle defect. There was substantial concordance regarding normal relaxation and anismus. Perfect concordance was found with rectocele and cystocele. The rectocele depth was measured with TLUS and quantified according to the EDF classification. Fair concordance was found for intussusception. There was no correlation between the displacement of the puborectal muscle at maximum straining on EDF with the displacement of the anorectal junction (ARJ), compared at rest with maximal straining on TLUS to determine perineal descent (PD). The mean ARJ displacement was similar in patients with normal and those with excessive PD on TLUS. CONCLUSIONS: Both modalities can be used as a method to assess pelvic floor dysfunction. The EDF using 3D anorectal and endovaginal approaches showed advantages in identification of the anal sphincters and pubodefects (partial or total). There was good correlation between the two techniques, and a TLUS rectocele classification based on size that corresponds to the established classification using EDF was established.

ABSTRACT

AIM: We assessed pubovisceral muscle (PVM) defects, levator hiatal dimensions and anal sphincter defects using three-dimensional (3D) endovaginal and anorectal ultrasonography in women with previous vaginal delivery and faecal incontinence to determine the relationship between anatomic/functional findings and severity of faecal incontinence symptoms. METHOD: This was a prospective, observational study including 52 women with faecal incontinence symptoms who had undergone vaginal delivery. Asymptomatic nulliparous women (n = 17) served as controls to provide reference values for pelvic floor measurements. All participants underwent 3D endovaginal and anorectal ultrasonography. We used an ultrasound score to identify and quantify the extent of PVM defects and sphincter damage and to measure levator hiatal dimensions. Incontinence was assessed using the Cleveland Clinic Florida Incontinence Scoring System. RESULTS: Defects of the PVM were identified with 3D endovaginal ultrasonography in 27% of women with faecal incontinence who had undergone vaginal delivery. The incontinence score and the ultrasound score were significantly higher in women with a PVM defect. A significant, positive correlation was found between the incontinence score and the ultrasound score. The levator hiatal dimensions were significantly greater, and the positions of the anorectal junction and bladder neck were lower, in women who had undergone vaginal delivery than in nulliparous women. CONCLUSION: As determined by the 3D ultrasound score, severity of incontinence is related to the extent of damage of the PVM, as well as of the anal sphincters. Additionally, vaginal delivery results in enlargement of the levator hiatus and a lower position of the anorectal junction and bladder neck compared with nulliparous women.

ABSTRACT

BACKGROUND: Knowledge of risk factors is particularly useful to prevent or manage pelvic floor dysfunction but although a number of such factors have been proposed, results remain inconsistent. The purpose of this study was to evaluate the impact of aging on the incidence of posterior pelvic floor disorders in women with obstructed defecation syndrome evaluated using echodefecography. METHODS: A total of 334 patients with obstructed defecation were evaluated using echodefecography in order to quantify posterior pelvic floor dysfunction (rectocele, intussusception, mucosal prolapse, paradoxical contraction or non-relaxation of the puborectalis muscle, and grade III enterocele/sigmoidocele). Patients were grouped according to the age (Group I = patients up to 50 years of age; Group II = patients over 50 years of age) to evaluate the isolated and associated incidence of dysfunctions. To evaluate the relationship between dysfunction and age-related changes, patients were also stratified into decades. RESULTS: Group I included 196 patients and Group II included 138. The incidence of significant rectocele, intussusception, rectocele associated with intussusception, rectocele associated with mucosal prolapse and 3 associated disorders was higher in Group II, whereas anismus was more prevalent in Group I. The incidence of significant rectocele, intussusception, mucosal prolapse and grade III enterocele/sigmoidocele was found to increase with age. Conversely, anismus decreased with age. CONCLUSIONS: Aging was shown to influence the incidence of posterior pelvic floor disorders (rectocele, intussusception, mucosa prolapse and enterocele/sigmoidocele), but not the incidence of anismus, in women with obstructed defecation syndrome.

ABSTRACT

AIM: The effect of vaginal delivery and ageing on the anatomy of the anal canal was assessed using three-dimensional anorectal ultrasound to determine the interobserver reliability. METHOD: One-hundred and eighteen asymptomatic women without sphincter damage were grouped according to parity and mode of delivery. They were then stratified by age (≤50 years vs >50 years). Group I consisted of 35 nulliparous women, of mean ages 36 years (n = 20) and 62 years (n = 15), Group II consisted of multiparous women, having one or more vaginal deliveries (n = 43), of mean ages 43 years (n = 20) and 60 years (n = 23) and Group III consisted of women who had a Caesarean section (n = 40) of mean ages 41 years (n = 20) and 56 years (n = 20). The groups were compared with regard to the length and the thickness of the external anal sphincter, the internal anal sphincter, the posterior external sphincter and the puborectalis in all quadrants and the anterior gap. Interobserver variability was assessed. RESULTS: In women having vaginal delivery the length of the anterior external sphincter was shorter (P = 0.0004) and the gap was longer (P = 0.0306). The external sphincter tended to be thinner in individuals having vaginal delivery (P = 0.0677) and in those subjects over 50 years of age having had a vaginal delivery (P = 0.0164). In nulliparous women, the internal sphincter was thicker in subjects over 50 years of age (P = 0.0229). The intraclass correlation coefficient was 0.755-0.916 for sphincter muscle and gap length and 0.446-0.769 for muscle thickness. CONCLUSION: Vaginal delivery was associated with a shorter anterior external sphincter, a longer gap and a thinner anterior external sphincter in asymptomatic women. Age was correlated with sphincter thickness, and nulliparous women >50 years of age had a thicker internal sphincter. Three-dimensional ultrasound was found to be a reliable method for measuring anal structures.

ABSTRACT

BACKGROUND: The aim of this prospective study was to evaluate the relationship between the pathogenesis of anorectocele and the anatomy of the anal canal and anorectal junction using echodefecography. METHODS: The study was conducted on a total of 100 women with obstructed defecation, mean age 46.6 years, who underwent echodefecography. Patients were classified based on rectocele status into group I, without rectocele (n = 32); group II, grade I rectocele (n = 11); group III, grade II (n = 27); and group IV, grade III (n = 30). We identified the layers of the anterior anorectal wall and measured anterior external sphincter length, posterior external sphincter and puborectalis length, gap between anterior external sphincter and anorectal junction, anorectal wall thickness in 3 locations: (1) proximal to anterior external anal sphincter; (2) anterior anorectal junction; (3) 1.0 cm proximal to anorectal junction. RESULTS: The anterior part of the external anal sphincter was significantly longer in group I (18.91 ± 0.38 mm) than in group III (16.94 ± 0.45 mm) (p < 0.05), and the length in group I was similar to that in group II (18.56 ± 0.44 mm) (p = 0.6223). The gap was significantly shorter in group I (21.24 ± 0.97 mm) than in group III (25.04 ± 0.82 mm) and group IV (23.82 ± 0.80 mm) (p < 0.05). The length of the anterior part of the external anal sphincter as a percentage of the length of the posterior external anal sphincter together with the puborectalis muscle was a mean of 57.39 ± 2.13% in group I, 56.01 ± 1.581% in group II, 47.77 ± 1.48% in group III, and 50.45 ± 1.61% in group IV, with a significantly higher percentage in group I than in groups III (p = 0.0126) and IV (p = 0.0007). No significant differences were identified between any of the groups regarding anorectal wall thickness at any of the 3 selected locations (p > 0.05). The muscularis propria layer of the rectal wall was not identified in 2 patients in group I (6.25%), 3 patients in group II (11.11%), and 3 patients in group III (10.00%), and 6 in group IV (8.82%), with no significant differences among groups. CONCLUSIONS: The pathogenesis of anorectocele may be associated with a shorter anterior part of the external anal sphincter and consequently a longer gap.

ABSTRACT

AIM: The purpose of the study was to describe a novel three-dimensional dynamic anorectal ultrasonography technique (dynamic 3-DAUS) for assessment of perineal descent (PD) and establishment of normal range values, comparing it with defaecography. Secondarily, the study compares the ability of the two techniques to identify various pelvic floor dysfunctions. METHOD: A prospective study was undertaken in 29 women (mean age 43 years) with obstructed defecation disorder. All patients underwent defaecography and dynamic 3-DAUS and the results were compared. Lee kappa coefficients (K) were used. RESULTS: On defaecography, PD > 3 cm was detected in 12 patients. On dynamic 3-DAUS, 10 of these patients had PD > 2.5 cm. Seventeen had normal PD on defaecography and PD ≤ 2.5 cm on dynamic 3-DAUS (K 0.85). Normal relaxation was observed in 10 patients and anismus in 14 with both techniques (K 0.65). Both techniques identified five patients without rectocele, two with grade I rectocele (K 0.89 and 1.00, respectively) and 10 with grade II and nine with grade III (K 0.72 and 0.77, respectively). Rectal intussusception was identified in six patients on defaecography. These were confirmed on dynamic 3-DAUS in addition to the identification of another seven cases indicating moderate agreement (K 0.46). Enterocele/sigmoidocele grade III was identified in one patient with both techniques, indicating substantial agreement (K 0.65). CONCLUSION: Dynamic 3-DAUS was shown to be a reliable technique for the assessment of PD and pelvic floor dysfunctions, identifying all disorders and confirming findings from defaecography.

ABSTRACT

AIM: The aim of this study was to identify criteria for three-dimensional anorectal ultrasonography (3D-AUS) to assess the response of rectal cancer to chemoradiotherapy; the 3D-AUS results were compared with the histopathological findings of the resected specimen. METHOD: Thirty-five patients underwent 3D-AUS and were grouped according to the presence (GI; n = 19) or absence (GII; n = 16) of anal canal invasion. All patients received chemoradiotherapy, then underwent a second 3D-AUS. The response (complete, partial or insignificant and lymph node metastasis) was evaluated. Tumour length (cm) and volume (cm(3) ), length and volume regression percentage (%), distal length regression, and distance between the distal tumour edge and the proximal border of the internal anal sphincter were measured before and after chemoradiotherapy. All patients underwent surgery, and the 3D-AUS image was compared with the histopathological findings. RESULTS: Before chemoradiotherapy, the average tumour length was similar in G1 and GII, but the volume differed significantly (P = 0.0408). The response was insignificant in seven (37%) patients, partial in 10 (53%) patients and complete in two (10%) patients in GI. The corresponding figures for GII were one (6%) patient, 12 (75%) patients and three (19%) patients (P = 0.0318). The agreement between pathological and post-chemoratherapy 3D-AUS findings was almost identical for the identification of residual tumour or complete response (κ = 1.0) and substantial for lymph node metastases (κ = 0.74). The mean distance to the internal anal sphincter was greater in GII. A sphincter-saving resection was performed in 2/19 patients in GI and in 14/16 patients in GII (P < 0.0001). The histopathological examination revealed a free distal margin. CONCLUSION: 3D-AUS was shown to evaluate accurately the response to chemoradiotherapy, helping in the selection of patients for a sphincter-saving resection. The distance between the tumour and the internal anal sphincter was the most important parameter in this respect.

ABSTRACT

AIM: We evaluated the impact of immunosuppressive drugs on the short-term outcome following loop ileostomy closure in patients with inflammatory bowel disease. METHOD: Data on 249 patients with inflammatory bowel disease, who underwent loop ileostomy closure from 2001 to 2008, were retrospectively reviewed from a prospectively maintained database. Patients were distributed among groups according to the inflammatory bowel disease drugs used. Comorbidity, diagnosis, intra-operative and postoperative morbidity and length of stay data were analysed. Patients in group (INF) were receiving infliximab with or without other immunosuppressive agents (28), patients in group (S) were receiving only steroids (72) and those, in group III (S&I) were on steroids plus immunosuppressive agents, other than infliximab (35). Patients in group (ND) had not received any immunosuppressive agents for 2 months and served as the control group (114). RESULTS: Postoperative complication rates (wound infection, hernia, obstruction, intra-abdominal abscess, leakage, enterocutaneous fistula and sepsis) occured in 4.0, 12.0, 14 and 17.0% of patients in the four groups (P > 0.05). Reoperation was needed in 3.0% (2) of patients in group S, 6.0% (2) in S&I and 3.0% (3) in C groups, and the mean hospital stay was 4.6 (± 2.1), 5.6 (± 4.6), 5.2 (± 4.7) and 5.2 (± 6) days in groups INF, S, S&I and ND, respectively. There was no mortality. CONCLUSION: There were no significantly increased postoperative complications after ileostomy closure in patients who received infliximab or other immunosuppressive medications compared with patients who did not.

ABSTRACT

BACKGROUND: The aim of the present study was to make a preoperative and postoperative clinical and functional evaluation of patients who underwent transanal repair of rectocele and rectal mucosectomy with a single circular stapler (TRREMS procedure) as treatment for obstructed defecation syndrome (ODS) caused by rectocele and rectal mucosal prolapse (RMP). METHODS: This prospective study included 35 female patients, 34 multiparous and one nulliparous, with an average age of 47.5 years (range 31-67 years), rectocele grade II (n = 13/37.1%) or grade III (n = 22/62.9%), associated with RMP. The study parameters included ODS, constipation, functional continence scores and pre- and postoperative cinedefecographic findings. RESULTS: The average preoperative ODS score, the constipation score and the functional continence score were significantly reduced after surgery from 10.63 to 2.91 (p = 0.001), 15.23 to 4.46 (p = 0.001) and 2.77 to 1.71 (p = 0.001), respectively. Between the first and the eighth postoperative day, the average visual analog scale pain score fell from 5.23 to 1.20 (p = 0.001). Satisfaction with treatment outcome was 79.97, 86.54, 87.65 and 88.06 at 1, 3, 6 and 12 months, respectively. Cinedefecography revealed average reductions in rectocele size from 19.23 ± 8.84 mm (3-42) to 6.68 ± 3.65 mm (range 0-7) at rest and from 34.89 ± 12.30 mm (range 20-70) to 10.94 ± 5.97 mm (range 0-25) during evacuation (both P = 0.001). CONCLUSION: The TRREMS procedure is a safe and efficient technique associated with satisfactory anatomic and functional results and with a low incidence of postoperative pain and complications.

ABSTRACT

OBJECTIVE: The aim of this prospective study was to test two-dimensional dynamic anorectal ultrasonography (2D-DAUS) in the assessment of anismus and compare it with echodefecography (ECD). METHOD: Fifty consecutive female patients with outlet delay were submitted to 2D and 3D-DAUS, measuring the relaxing or contracting puborectalis muscle angle during straining. The patients were assigned to one of two groups based on ECD findings. Group I consisted of 29 patients without anismus and group II included 21 patients diagnosed with anismus. Subsequently 2D-DAUS images were checked for anismus and compared with ECD findings. RESULTS: Upon straining, the angle produced by the movement of the puborectalis muscle decreased in 26 out of the 29 (89.6%) patients of group I and increased 19 out of the 21 (90.4%) patients of group II. The mean angle during straining differed significantly between group I and group II. The index of agreement between the two scanning modes was 89.6% (26/29) for group I (Kappa: 0.796; CI: 95%; range: 0.51-1.0) and 90.4% (19/21) for group II (Kappa: 0.796; CI: 95%; range: 0.51-1.0). CONCLUSION: Two-dimensional dynamic anal ultrasonography can be used as an alternative method to assess patients with anismus, although the 3-D modality is more precise to evaluate the PR angle as the sphincters integrity as the whole muscle length is clearly visualized.

ABSTRACT

OBJECTIVE: The study aimed to verify the role of parity, age and bowel function in the pathogenesis of anorectocele. METHOD: A cross-sectional study was conducted regarding age, obstetrical history, Cleveland Clinic Constipation Score (CCCS), cinedefecography and anal manometry findings. Forty-five adult women complaining of obstructed defecation were evaluated; the median age was 46 years and median CCCS, 13. Fifteen patients were nulliparous and 23 multiparous (median parity 2). Eighteen had a history of episiotomy, fourteen delivered large babies and two had forceps-assisted delivery. Statistical analysis was performed using Spearman's correlation test and Fisher's exact test. RESULTS: Anal hypertonia was found in 14 (31.1%) patients, anal hypotonia in eight (17.8%), anismus in 13 (28.9%) and anorectoceles in 34 (75.6%) [median size 2.8 cm (0-6.4)]. There were no correlations between anorectocele and anal hypertonia (P = 0.7171), anismus (P = 0.4666), parity comparing nulliparous and multiparous patients (P = 1.000), episiotomy (P = 1.0000), forceps assistance (P = 1.0000), delivery of a large baby (P = 1.0000) anal resting pressure (P = 0.0883), anal voluntary pressure (P = 0.7327), parity (P = 0.4987) and age (P = 0.8603). There were correlations between anorectocele and the CCCS (P = 0.0082) and anal hypotonia (P = 0.0141). CONCLUSION: Anorectocele is not correlated with parity, age, episiotomy, delivery of a large baby and anismus. It was more frequent in patients with severe constipation and less common in patients with anal hypotonia.

ABSTRACT

PURPOSE: The effects of rapid sustained inflation versus rapid inflation/deflation of the intrarectal balloon upon rectoanal inhibitory reflex (RAIR) parameters were evaluated in asymptomatic subjects. METHODS: Forty asymptomatic adults were submitted to anorectal manometry with rapid or sustained inflation with 30 and 60 mL air. The average age was 27.4 years (range, 20-40). The subjects were divided into Group I (20 men) and Group II (20 women) for analysis. RAIR parameters were registered in order to compare the inflation patterns within each group, and Groups I and II were compared for each inflation pattern with regard to RAIR parameters. RESULTS: Sustained inflation significantly increased IAS relaxation time and duration of the reflex in both groups, and IAS tone recovery time in Group I. CONCLUSIONS: RAIR parameters are influenced by the choice of inflation pattern. Further studies are required to establish a standard intrarectal balloon inflation pattern.

ABSTRACT

OBJECTIVE: This study aimed to determine the value of three-dimensional (3D) dynamic endosonography in the assessment of anismus. METHOD: Sixty-one women submitted to anorectal manometry were enrolled including 40 healthy women and 21 patients with anismus diagnosed by manometry. Patients were submitted to 3D endosonography. Images were acquired at rest and during straining and analysed in axial and midline longitudinal planes. Sphincter integrity was quantified. The angle between the internal edge of the puborectalis with a vertical line according to the anal canal axis was calculated at rest and during straining. RESULTS: The angle increased in 39 of the 40 normal individuals and decreased in all patients with anismus during straining compared with the angle at rest (88.36 degrees ) and straining (98.65 degrees ) in normal individuals. In the anismus group, the angle decreased at rest (90.91 degrees ) and straining (84.89 degrees ). The difference between angle sizes in normal and anismus patients during straining was statistically significant (P < 0.5). CONCLUSION: Three-dimensional endosonography is a useful method to assess patients with anismus confirming the anorectal manometric results.

ABSTRACT

OBJECTIVE: The anatomy of the anal canal, the anorectal junction and the lower rectum was studied with 3-D ultrasound. METHOD: Seventeen women with normal bowel transit, without rectocele (group 1) and 17 female patients with a large anterior rectocele (group 2) were examined with a B&K Medical Rawk. Mean age was 44.5 and 51.6 years respectively. In group 1, one (5.8%) patient was nuliparous, five (29.4%) had a caesarian section, 11 (64.7%) had a vaginal delivery while in group 2, two (11.7%) patients were nuliparous, four (23.5%) had a caesarian section and 11 (64.7%) had a vaginal delivery. Images were reconstructed in midline longitudinal (ML) and transverse (T) planes. The external (EAS) and internal (IAS) anal sphincters were measured in both projections. RESULTS: In the ML plane, the EAS length was longer in group 1 (1.94 cm vs 1.61 cm, P < 0.05), the gap length was shorter (1.54 cm vs 1.0 cm P < 0.01) and the wall thickness was shorter in group 2 (0.40 cm vs 0.50 cm P < 0.01). The IAS (0.18 cm vs 0.23 cm P < 0.01) and EAS thickness (0.68 cm vs 0.77 cm, P < 0.05) (left lateral of the posterior quadrant) was greater in group 2. In group 1, the anterior upper anal canal wall in normal females was an extension of the rectal wall and the circular muscle was thicker in the mid-anal canal to form the IAS. In group 2, however, the wall layers were not identified and the IAS was found to be more distal. The differences were not statistically significant in the anal canal resting and squeeze pressures in the two groups. CONCLUSION: Obstetric trauma does not seem to play any role in rectocele pathogenesis because the anal sphincter muscles are anatomically and functionally normal and rectocele is also present in nuliparous and in women with caesarian sections. It seems that it is associated with the absence of EAS and thinner IAS in the anterior upper anal canal. Herniation starts at the upper anal canal extending to the lower rectum in high or large rectoceles and maybe produced by rectal intussusception because of excessive and prolonged straining during defecation. In fact, the denomination 'rectocele' should be changed to 'anorectocele'.

ABSTRACT

We present a new surgical stapling technique for treatment of rectocele when associated with internal mucosal prolapse or haemorrhoids using only one circular mechanical stapler. Eight female patients, mean age 53 years (range, 42-70), complaining of obstructed defecation with vaginal digitation because of rectocele associated with internal mucosal prolapse underwent transanal repair of rectocele and rectal mucosectomy using one circular stapler between April and July 2004. A running horizontal mattress suture was placed through the base of the rectocele including mucosa, submucosa and the muscle layer of the whole anterior anorectal junction wall. The prolapsed mucosa and the muscular layer were then excised with an electrical scapel. A continuous pursestring rectal mucosa suture was placed 0.5 cm before the previous anterior mucosa and muscle layers resected wound, including the anorectal junction wall which was kept separate from the posterior vaginal wall by a Babcock forceps. Posteriorly, the pursestring suture included only mucosal and submucosal layers. The stapled suture was positioned between normal anterior rectal wall and the anal canal, 0.5 cm above the pectinate line. The stapler was then closed, fired and withdrawn. One patient complained of a perianal hematoma on the seventh postoperative day, requiring surgical excision. Postoperative defecography showed correction of the rectocele and outlet obstruction disappeared in all patients. This novel combined manual-stapled technique for rectocele and rectal internal mucosal prolapse seems to be a safe procedure and the preliminary results are encouraging. Further investigations have to be performed to assess long-term outcome in a larger number of patients.
