    Full Text Available Obstetric anal sphincter injuries can be associated with significant short and long term consequences causing devastating impacts on the quality of lives of young, otherwise healthy women. The major consequence is anal incontinence which may be short or long term and vary in severity. The other consequences include pain, infection, dyspareunia and sexual dysfunction. This may in turn result in considerable economic burden to health care providers and patients. It also has an implication on future deliveries. Although it can never be eliminated, it can be reduced by improving practice, training and provision of high quality multidisciplinary care in order to reduce long-term morbidity. Obstetric anal sphincter injuries are also a source of litigation which can be distressing to both patients and clinicians. The aim of this review article is to explore the available evidence on epidemiology, strategies for preventions, prognosis and also how to deal with governance issues.

    BACKGROUND: Anal incontinence is a major concern following delivery with obstetric anal sphincter injury and has been related to the degree of sphincter tear. OBJECTIVES: To 1) evaluate whether women with a fourth degree obstetric anal sphincter injury in the first delivery have an increased risk...... of long-term anal- and fecal incontinence after a second delivery and 2) assess the impact of mode of second delivery on anal incontinence and related symptoms in these patients. STUDY DESIGN: We performed secondary analyses of a national questionnaire study in all Danish women with an obstetric anal...... performed uni- and multivariable logistic regression analyses to evaluate the outcomes. RESULTS: In total, 2,008 patients had an obstetric anal sphincter injury of which 12.2% (n=245) had a fourth degree tear in the first delivery. The median follow-up time since the first delivery with OASIS was 11.6 years...

    Full Text Available Background: Anal sphincter tears during vaginal delivery may result in serious sequel. Anal sphincter tears occur in approximately 2–19 % of all vaginal deliveries and are the most common precursor for faecal incontinence,1 however »occult« anal sphincter injury has been defined in 33 % of primiparous women following vaginal delivery.2 Methods: 31-year old primiparous woman received transfusion due to atony after delivery. Episiotomy, second degree perineal tear and vaginal tear were surgically corrected immediately after delivery. In the following days inability to control passing of liquid stools and flatulence together with stress urinary incontinence appeared. The complaint persisted. Ultrasound and EMG examination confirmed rupture of the external anal sphincter, which had been missed at delivery. Over a year after delivery the patient had a posterior colporraphy with surgical correction of external anal sphincter, which did not result in any clinical improve- ment. On follow-up ultrasound examination a hypoechoegenic area between the external sphincter and vaginal wall was detected. The patient was referred to The University Hos- pital in Graz, where the tear will be treated with autologous myoblast transplantation in a clinical trial. Conclusions: Treatment of a missed anal sphincter tear is complicated, expensive and unpleasant for the patient. Early detection with immediate appropriate surgical correction after delivery is most efficient, but it takes experience.

    Full Text Available Background: Anal incontinence severely impairs quality of life. It affects 4 to 19 % of women and is statistically related to number of vaginal deliveries. It is grossly underreported and most patients that do seek help are referred to gastroenterologists or colorectal surgeons. Incidence of recognized sphincter injuries at time of delivery is 1 to 2 %. However studies with anal ultrasound showed incidence of anal sphincter injuries at 28 to 41 %. Depending on the degree of injury symptoms range from partial to complete inability to control passing of winds, liquid or solid stools. About three thirds of patients are asymp- tomatic in puerperium, however half of them are at risk of developing anal incontinence in later life. Hypoestrogenisem, additional perineal trauma during consequent deliveries and sphincter atrophy can unmask anal sphincter damage years later. Timely recognition and treatment are vital for good long term results and quality of life, if possible immediately after delivery. Good knowledge of perineal anatomy, recognition of risk factors, intense search and appropriate treatment and follow-up are essential to management of anal sphincter injuries. All secondary sphincter repair is less effective. Content: Updated overview of current opinion and guidelines on anal sphincter injuries are pre- sented. Anal sphincter is composed of external anal sphincter (EAS and internal anal sphincter (IAS. Striated EAS is divided into three parts – subcutaneous, superficial, deep, and con- nected to puborectalis muscle posteriorly. Smooth-muscled IAS is a continuation of a cir- cular smooth-muscle layer of rectum. In between there is a thin longitudinal muscle layer. IAS constitutes 70 % of resting tone and is under constant contraction. EAS contributes to 30 % of resting tone and almost all pressure during active contraction. EAS injury leads to insufficient contraction after rectal sampling and filling which causes urgency – patient can

    first birth, Asian race, a vaginal birth after cesarean, and type of obstetrical care provider 4 . Possible protective factors include obesity, perineal massage (RR 0.91, 95% CI 0.86-0.96) 5 , perineal protection at crowning 3 , warm compression during the second stage of labor (RR 0.48, 95% CI 0.28-0.84) 3 , mediolateral episiotomy in instrumental deliveries 6 , a wide angle of the mediolateral episiotomy (at least 60 degrees away from the midline when the perineum is distended) 7 , and pre-labor cesarean section 4 . However, clinicians and patients alike should be aware that risk factors do not allow the accurate prediction of OASI 3 . OASI is usually diagnosed in the immediate postpartum period. The classification is based on the extent of lacerations to the external and internal anal sphincter (EAS and IAS, respectively) and epithelium as devised by Sultan 2,3,8 (Figure 1) and adopted by the World Health Organization (WHO). The degree of damage impacts on the development of symptoms, with 3C and 4 th degree tears carrying a graver prognosis than 3A and 3B tears 9 . It is not unusual for a tear to be missed in the labor ward: the reported rates of missed OASI range from 26-87% 10 . Since all women having a vaginal delivery are at risk of sustaining OASI, they should be examined systematically, including a digital rectal examination, to assess the severity of damage, prior to suturing 3 .

    Shoulder dystocia is an obstetric emergency that occurs in 0.2-3% of all cephalic vaginal deliveries. We hypothesized that because of the difficult nature of deliveries complicated by shoulder dystocia, the condition may be associated with anal sphincter injury. We sought to identify risk factors for obstetric anal sphincter injury in women with shoulder dystocia. This retrospective analysis included all cases of shoulder dystocia from 2007 to 2011 at two large tertiary referral centers, in the USA and Ireland. Details of maternal demographics, intrapartum characteristics, and delivery outcomes in cases of shoulder dystocia were analyzed. Univariate and multivariate analyses were used to describe the association between shoulder dystocia and anal sphincter injury. There were 685 cases of shoulder dystocia, and the rate of shoulder dystocia was similar at both institutions. The incidence of anal sphincter injury was 8.8% (60 out of 685). The rate was 14% (45 out of 324) in nulliparas and 4.2% (15 out of 361) in multiparas. Women with sphincter injury were more likely to be nulliparous (75% [45 out of 60] vs 45% [279 out of 625]; p shoulder dystocia, the risk of anal sphincter injury is 9%. Risk factors include nulliparity, operative vaginal delivery, and use of internal maneuvers, whereas episiotomy was found to have a protective effect against anal sphincter injury during cases of shoulder dystocia.

    To assess the effect of vaginal delivery and caesarean section on faecal symptoms and structure and function of anal sphincter in women who sustained obstetric anal sphincter injuries (OASIS) in their previous pregnancy and were advised about the mode of delivery based on faecal incontinence symptoms, anal manometry and endoanal ultrasound. It is a descriptive study on a cohort of women who had OASIS from 2006 to 2013. They were assessed after OASIS and during subsequent pregnancy with a questionnaire, endoanal ultrasound and anal manometry. Vaginal delivery was recommended to asymptomatic women with normal investigations. Elective caesarean section was recommended to women with faecal symptoms, anal sphincter defects of more than 30° or low resting or incremental anal pressures. All women were reassessed after subsequent delivery. Fifty women who had pregnancies after OASIS, were seen after OASIS, during subsequent pregnancy and after the second delivery. 15 women had faecal symptoms after OASIS. The external, internal and combined anal sphincter defects were seen in 13, 11 and 9 women respectively. Low resting and incremental pressure were seen in 15 and 11 women respectively. Caesarean section was done in 22 women and 28 women delivered vaginally. Worsening of faecal symptoms and reduction in anal pressures were not observed in planned vaginal delivery or elective caesarean section groups. Faecal symptoms were worse with reduced anal pressures in three women from the planned caesarean section group. One of the women had a vaginal delivery and two women had emergency caesarean section at 7cm and 10cm dilatation. There were no new sphincter defects or recurrent OASIS in any of the women in the study group. Decision about the mode of delivery of pregnancy after OASIS based on symptoms, anal manometry and endoanal ultrasound helps in preserving the anal sphincter function and avoiding unnecessary caesarean sections. Further follow-up of these patients is essential

  1. Thermal responses of shape memory alloy artificial anal sphincters

    Luo, Yun; Takagi, Toshiyuki; Matsuzawa, Kenichi

    2003-08-01

    This paper presents a numerical investigation of the thermal behavior of an artificial anal sphincter using shape memory alloys (SMAs) proposed by the authors. The SMA artificial anal sphincter has the function of occlusion at body temperature and can be opened with a thermal transformation induced deformation of SMAs to solve the problem of severe fecal incontinence. The investigation of its thermal behavior is of great importance in terms of practical use in living bodies as a prosthesis. In this work, a previously proposed phenomenological model was applied to simulate the thermal responses of SMA plates that had undergone thermally induced transformation. The numerical approach for considering the thermal interaction between the prosthesis and surrounding tissues was discussed based on the classical bio-heat equation. Numerical predictions on both in vitro and in vivo cases were verified by experiments with acceptable agreements. The thermal responses of the SMA artificial anal sphincter were discussed based on the simulation results, with the values of the applied power and the geometric configuration of thermal insulation as parameters. The results obtained in the present work provided a framework for the further design of SMA artificial sphincters to meet demands from the viewpoint of thermal compatibility as prostheses.

    The purpose of this work is to evaluate the electromyography value of anal sphincter in patients with anorectal dysfunctions. Anorectal dysfunctions are frequent reason of pediatric consultation in children, especially with anal incontinence. A study of series of cases in patient with anorectal dysfunctions was carried out from January 2002 to January of 2006. 65 patients were studied. Anorectal malformations (ARM) represented the predominant affection with 38 patients (58.5%), prevailing the male sex in 25 patients (65.8%). Encopresis and intestinal agagliosis dicrease was observed. Sphincter was found before surgical treatment through electromyography in patients with anorectal malformations and colostomy; in those with definitive operation and open colostomy, it avoided the operation in a patient that did not have muscular activity of the external sphincter. In children already operated and with closed colostomy several electromyography changes were observed in correspondence with different incontinence grades. In encopresis cases the study was useful to rule out sphincter functional alterations. Electromyography was pathological in all the operated patients of intestinal aganglionosis. This procedure was very useful for anal incontinence study that helped to determine and establish the prognosis. (author)

    We have devised a modified seton technique that resects the external fistula tract while preserving the anal sphincter muscle. This study assessed the technique when used for the management of complex anal fistulas. Between January 2006 and December 2007, 239 patients (208 males and 31 females, median age: 41 years) underwent surgery for complex anal fistulas using the technique. Of the 239 patients, 198 patients had trans-sphincteric fistula and 41 patients had supra-sphincteric fistula. The durations of the surgeries were 17 min (47, 13) [median (range, interquartile range)] for trans-sphincteric fistulas and 38 (44, 16) for supra-sphincteric fistulas. The durations of the surgeries were significantly (P supra-sphincteric fistula than trans-sphincteric fistula. The hospital stays were 4 (13, 2) days and 5 (14, 3) days, respectively, for trans- and supra-sphincteric fistulas. The durations of seton placement until the spontaneous dropping of the seton were 42 (121, 48) and 141 (171, 55) days respectively. The recurrence rate was 0 % in patients with trans-sphincteric fistulas and 4.9 % (2 of 41) in patients with supra-sphincteric fistulas (P < 0.01). Serious incontinence was not observed. The technique provided favorable results for the treatment of complex anal fistulas and could be safely applied while preserving the sphincter function and conserving fecal continence.

    Obstetric sphincter damage is the most common cause of fecal incontinence in women. This review aimed to survey the literature, and reach a consensus, on its incidence, risk factors, and management. This systematic review identified relevant studies from the following sources: Medline, Cochrane database, cross referencing from identified articles, conference abstracts and proceedings, and guidelines published by the National Institute of Clinical Excellence (United Kingdom), Royal College of Obstetricians and Gynaecologists (United Kingdom), and American College of Obstetricians and Gynecologists. A total of 451 articles and abstracts were reviewed. There was a wide variation in the reported incidence of anal sphincter muscle injury from childbirth, with the true incidence likely to be approximately 11% of postpartum women. Risk factors for injury included instrumental delivery, prolonged second stage of labor, birth weight greater than 4 kg, fetal occipitoposterior presentation, and episiotomy. First vaginal delivery, induction of labor, epidural anesthesia, early pushing, and active restraint of the fetal head during delivery may be associated with an increased risk of sphincter trauma. The majority of sphincter tears can be identified clinically by a suitably trained clinician. In those with recognized tears at the time of delivery repair should be performed using long-term absorbable sutures. Patients presenting later with fecal incontinence may be managed successfully using antidiarrheal drugs and biofeedback. In those who fail conservative treatment, and who have a substantial sphincter disruption, elective repair may be attempted. The results of primary and elective repair may deteriorate with time. Sacral nerve stimulation may be an appropriate alternative treatment modality. Obstetric anal sphincter damage, and related fecal incontinence, are common. Risk factors for such trauma are well recognized, and should allow for reduction of injury by proactive

    SSc is a connective tissue, multisystem disorder of unknown aetiology. The gastrointestinal tract (GIT) is affected in up to 90% of patients. The exact pathophysiology of GIT involvement is not known, but it is related to both neurogenic and myogenic abnormalities as well as possible vascular and ischaemic changes. Thinning of the internal anal sphincter (IAS) has been demonstrated in SSc with faecal incontinence. We aimed to investigate anal sphincter structure in patients with SSc. Forty-four SSc patients [24 symptomatic (Sx) and 20 asymptomatic (ASx)] and 20 incontinent controls (ICs) were studied. Patients underwent anorectal manometry and endoanal US. In the ICs, external anal sphincter defects were more common, but the IAS was less atrophic, evident by both atrophy scores and IAS thickness. There was no significant difference in atrophy scores [Sx: 2 (1.5-3) vs ASx: 2 (1-2)] or IAS thickness [Sx: 1.85 (1.5-2.3) vs ASx: 1.8 (1.7-2.25)] between the Sx and ASx SSc patients. Patients with SSc (both Sx and ASx) have thin and atrophic IAS, suggesting that IAS atrophy develops even in ASx patients and this may be amenable to treatment with sacral neuromodulation.

    Obstetric anal sphincter injury is common but the effect on body image is unreported. The aim of this study was to explore patient perceived changes in body image and other psychological aspects in women attending a perineal follow-up clinic. This retrospective study analysed women's responses to a self-reported questionnaire. Consecutive women with anal sphincter injury who attended a United Kingdom Maternity Hospital perineal follow-up clinic between January 1999 and January 2012 were identified and the records obtained and reviewed. Multivariate regression analyses were performed to examine variables influencing self-reported change in body image. Questionnaires and operation notes were analysed from 422 women who attended at a median of four months after delivery. 222 (53%) reported a change in body image with 80 (19%) reporting lower self-esteem and 75 (18%) a change in their personality due to the change in body image. 248 (59%) perceived an anatomical change due to the delivery. Factors associated with increased likelihood of reporting a change in body image were reporting a perceived change in anatomy due to the delivery, adjusted OR 6.11 (3.56-10.49), anal incontinence, OR 1.97 (1.16-3.36), and delivery by forceps, OR 2.59 (1.23-5.43). This is the first study to quantify body image changes in women after anal sphincter injury sustained in childbirth. These were found to be very common, affecting up to 50% of women. The study has several limitations but it does highlight the significant psychosocial problems of negative self-esteem and personality changes associated with a perceived change in body image that has not previously been reported. It also outlines the further research questions that need to be addressed. Copyright © 2017 Elsevier B.V. All rights reserved.

    Background. The aim of the study was to visualize, by anal ultrasound (AUS), the suspected defects of the anal sphincters in the patients after colostomy and to analyze possible factors that could have led to such defects. Patients and methods. AUS, using a 7.0 MHz endorectal probe, was performed in a group of 25 patients with colostomy. The internal anal sphincter (IAS), external anal sphincter (EAS) and puborectalis muscle (PR) were visualized and the defects within them were qualified and quantified. For statistical analysis, the analysis of variance (ANOVA) was used. Results. The IAS was thin in all but three patients (22 patients; 88 %) with the mean thickness of 1.62 mm. A circular reduction of the thickness along the entire length of the IAS was seen in 20 patients (90.9 %). The echogenicity of the IAS was increased in 15 patients (60 %), and in 10 of them (66.6%), this defect embraced the whole length and circumference of the IAS. The margins of the IAS were not well-defined in 10 patients (40%). A significant correlation was found between the length of the patient's life with the stoma and the IAS echogenicity defect (p-value = 0.0001). No significant correlation was found between the dynamic examination, the IAS thickness and the IAS borders definition. Conclusion. The reduced thickness, increased echogenicity and borders definition defect of the IAS are seen in the patients after colostomy. The only significant correlation was confirmed between the length of the patient's life with the stoma and the IAS echogenicity defect. (author)

    To evaluate anal sphincter anatomy using three-dimensional ultrasonography (3-DAUS) in incontinent women with vaginal delivery, correlate anatomical findings with symptoms of fecal incontinence and determine the effect of vaginal delivery on anal canal anatomy and function. Female with fecal incontinence and vaginal delivery were assessed with Wexner's score, manometry, and 3DAUS. A control group comprising asymptomatic nulliparous was included. Anal pressure, the angle of the defect and length of the external anal sphincter (EAS), the anterior and posterior internal anal sphincter (IAS), the EAS + puborectal and the gap were measured and correlated with score. Of the 62, 49 had fecal incontinence and 13 were asymptomatic. Twenty five had EAS defects, 8 had combined EAS+IAS defects, 16 had intact sphincters and continence scores were similar. Subjects with sphincter defects had a shorter anterior EAS, IAS and longer gap than women without defects. Those with a vaginal delivery and intact sphincters had a shorter anterior EAS and longer gap than nulliparous. We found correlations between resting pressure and anterior EAS and IAS length in patients with defects. Fecal incontinence symptoms did not correlate with anal pressures and anal sphincter anatomy changes, but women with sphincter defects have shorter anterior EAS and IAS and a longer gap.

    To compare the sensitivity and specificity of two- (2D) and three- (3D) dimensional transperineal ultrasound (TPUS) and 3D endovaginal ultrasound (EVUS) with the gold standard 3D endoanal ultrasound (EAUS) in detecting residual defects after primary repair of obstetric anal sphincter injuries (OASIS). External (EAS) and internal (IAS) anal sphincters were evaluated by the four ultrasound modalities in women with repaired OASIS. 2D-TPUS was evaluated in real-time, whereas 3D-TPUS, 3D-EVUS and 3D-EAUS volumes were evaluated offline by six blinded readers. The presence/absence of any tear in EAS or IAS was recorded and defects were scored according to the Starck system. Sensitivity, specificity and predictive values were calculated, using 3D-EAUS as reference standard. Inter- and intraobserver analyses were performed for all 3D imaging modalities. Association between patients' symptoms (Wexner score) and ultrasound findings (Starck score) was calculated. Images from 55 patients were analyzed. Compared with findings on 3D-EAUS, the agreement for EAS evaluation was poor for 3D-EVUS (κ = 0.01), fair for 2D-TPUS (κ = 0.30) and good for 3D-TPUS (κ = 0.73). The agreement for IAS evaluation was moderate for both 3D-EVUS (κ = 0.41) and 2D-TPUS (κ = 0.52) and good for 3D-TPUS (κ = 0.66). Good intraobserver (3D-EAUS, κ = 0.73; 3D-TPUS, κ = 0.78) and interobserver (3D-EAUS, κ = 0.68; 3D-TPUS, κ = 0.60) agreement was reported. Significant association between Starck and Wexner scores was found only for 3D-EAUS (Spearman's rho = 0.277, P = 0.04). 2D-TPUS and 3D-EVUS are not accurate modalities for the assessment of anal sphincters after repair of OASIS. 3D-TPUS shows good agreement with the gold standard 3D-EAUS and a high sensitivity in detecting residual defects. It, thus, has potential as a screening tool after primary repair of OASIS. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd. Copyright © 2016 ISUOG

    BACKGROUND: Internal anal sphincter achalasia (IASA) is a condition with presentation similar to Hirschsprung\\'s disease (HD), but with the presence of ganglion cells on rectal suction biopsy (RSB). The diagnosis is made on anorectal manometry (ARM) by the absence of the rectosphincteric reflex on rectal balloon inflation. Internal sphincter myectomy (ISM) is the treatment of choice for patients with IASA. Recently, botulinum toxin has been used to treat IASA patients. The purpose of this study was to assess the long-term bowel function in patients with IASA following ISM. METHODS: The medical records of 24 patients with IASA managed by ISM during 1993-2005 were examined. There were 18 boys and 6 girls, aged 2-12 years. All patients presented with intractable constipation with or without soiling. The diagnosis was made by the demonstration of the absence of the rectosphincteric reflex on ARM. HD was excluded by the presence of ganglion cells and normal acetylcholinesterase activity in RSB. Patients were followed 4-14 years later. RESULTS: Fifteen (62.5%) patients at the time of follow-up had regular bowel motions without the use of laxatives. Six (25%) patients had regular bowel motions, but remained on small doses of laxatives. Two (8.3%) patients who suffered from constipation and soiling required twice weekly enemas to remain clean. One (4.2%) patient required resection of dilated rectosigmoid colon 3 years after myectomy, remains on laxatives, but has normal bowel control. No patients had faecal incontinence following ISM. CONCLUSION: This long-term follow-up study shows that the vast majority of IASA patients have normal bowel control following ISM.

    Ultrasonographic studies in healthy volunteers showed that the external anal sphincter (EAS) and internal anal sphincter (IAS) thicknesses were inversely related at rest. The functional importance of the two sphincters in continence control was demonstrated in the relationship between the sum of the thicknesses of the two sphincters and the anal canal resting pressure. The aims of the present study were to assess the morphometric appearance of the anal sphincters by endosonography in faecally incontinent patients and to contrast this with that of older healthy subjects. Twenty-eight female patients with neurogenic faecal incontinence (FI) were studied. An older group of 7 healthy women, aged 41-75 years, and a young group of 11 nulliparous healthy women, aged 20-23 years, served as control groups. Anal endosonography was performed with a radial rotating endoprobe, with the subject in the left lateral position. Conventional anal manometry was performed in all subjects. The EAS in the FI group was thicker than the EAS in the old (p IAS thickness in the FI group did not differ from that in the older group. In both these groups the IAS was thicker than in the young women (p IAS in the FI group does not seem to compensate for function and results in a failure of the sphincter mechanism to maintain continence, whereas in healthy elderly subjects the increased IAS thickness appears to be compensatory and important for continence control.

    The use of a surface coil in MR imaging improves signal-to-noise ratio of adjacent tissues of interest. We therefore devised an endoanal receiver coil for imaging the anal sphincter. The probe is solid and re-usable: it comprises a saddle geometry receiver with integral tuning, matching and decoupling. It is placed in the anal canal and immobilised externally. Both in vitro and in vivo normal anatomy is identified. The mucosa is high signal intensity, the submucosa low signal intensity, the internal sphincter uniformly high signal intensity and the external sphincter low signal intensity on T1- and T2-weighted images. In females, the transverse perineal muscle bridges the inferior part of the external sphincter anteriorly. In perianal sepsis, collections and the site of the endoanal opening are identified. In early-onset fecal incontinence following obstetric trauma/surgery, focal sphincter defects are demonstrated; in late-onset fecal incontinence external sphincter atrophy is seen. In fecally incontinent patients with scleroderma, forward deviation of the anterior sphincter musculature with descent of rectal air and feces into the anal canal is noted. The extent of sphincter invasion is assessed in low rectal tumours. In children with congenital anorectal anomalies, abnormalities of the muscle components are defined using smaller-diameter coils. Such information is invaluable in the assessment and surgical planning of patients with a variety of anorectal pathologies. (orig.) With 15 figs., 26 refs.

    Aim: To determine the accuracy and predictive value of transperineal (TPU) and endovaginal ultrasound (EVU) in the detection of anal sphincter defects in women with obstetric anal sphincter injuries and/or postpartum symptoms of faecal incontinence. Materials and methods: One hundred and sixty-five women were recruited, four women were excluded as they were seen years after their last delivery. TPU and EVU, followed by endonanal ultrasound (EAU), were performed using the B and K Viking 2400 scanner. Sensitivity and specificity, as well as predictive values with 95% confidence intervals, for detecting anal sphincter defects were calculated for EVU and TPU, using EAU as the reference standard. Results: On EAU a defect was found in 42 (26%) women: 39 (93%) had an external (EAS) and 23 (55%) an internal anal sphincter (IAS) defect. Analysable images of one level of the EAS combined with an analysable IAS were available in 140 (87%) women for EVU and in 131 (81%) for TPU. The sensitivity and specificity for the detection of any defect was 48% (30-67%) and 85% (77-91%) for EVU and 64% (44-81%) and 85% (77-91%) for TPU, respectively. Conclusion: Although EAU using a rotating endoprobe is the validated reference standard in the identification of anal sphincter defects, it is not universally available. However while TPU and/or EVU with conventional ultrasound probes can be useful in identifying normality, for clinical purposes they are not sensitive enough to identify an underlying sphincter defect.

    Objective Anal sphincter complex consists of anatomically overlapping internal anal sphincter (IAS), external anal sphincter (EAS) & puborectalis muscle (PRM). We determined the functional morphology of anal sphincter muscles using high definition manometery (HDAM), 3D-ultrasound (US) and Magnetic resonance (MR) imaging. Patients We studied 15 nulliparous women. Interventions HDAM probe equipped with 256 pressure transducers was used to measure the anal canal pressures at rest and squeeze. Lengths of IAS, PRM and EAS were determined from the 3D-US images and superimposed on the HDAM plots. Movements of anorectal angle with squeeze were determined from the dynamic MR images. Results HDAM plots reveal that anal canal pressures are highly asymmetric in the axial and circumferential direction. Anal canal length determined by the 3D-US images is slightly smaller than measured by HDAM. The EAS (1.9 ± 0.5 cm long) and PRM (1.7 ± 0.4 cm long) surround distal and proximal parts of the anal canal respectively. With voluntary contraction, anal canal pressures increase in the proximal (PRM) and distal (EAS zone) parts of anal canal. Posterior peak pressure in the anal canal moves cranially in relationship to the anterior peak pressure, with squeeze. Similar to the movement of peak posterior pressure, MR images show cranial movement of anorectal angle with squeeze. Conclusion Our study proves that the PRM is responsible for the closure of the cranial part of anal canal. HDAM, in addition to measuring constrictor function can also record the elevator function of levator ani/pelvic floor muscles. PMID:21951657

    Purpose: To assess the frequency and magnitude of changes in lower rectal cancer resulting from preoperative therapy and its impact on sphincter-saving surgery. Preoperative therapy can increase the rate of preserving surgery by shrinking the tumor and enhancing its distance from the anal sphincter. However, reliable data concerning these modifications are not yet available in published reports. Methods and Materials: A total of 98 cases of locally advanced cancer of the lower rectum (90 Stage uT3-T4N0-N+ and 8 uT2N+M0) that had undergone preoperative therapy were studied by endorectal ultrasonography. The maximal size of the tumor and its distance from the anal sphincter were measured in millimeters before and after preoperative therapy. Surgery was performed 6-8 weeks after therapy, and the histopathologic margins were compared with the endorectal ultrasound data. Results: Of the 90 cases, 82.5% showed tumor downsizing, varying from one-third to two-thirds or more of the original tumor mass. The distance between the tumor and the anal sphincter increased in 60.2% of cases. The median increase was 0.73 cm (range, 0.2-2.5). Downsizing was not always associated with an increase in distance. Preserving surgery was performed in 60.6% of cases. It was possible in nearly 30% of patients in whom the cancer had reached the anal sphincter before the preoperative therapy. The distal margin was tumor free in these cases. Conclusion: The results of our study have shown that in very low rectal cancer, preoperative therapy causes tumor downsizing in >80% of cases and in more than one-half enhances the distance between the tumor and anal sphincter. These modifications affect the primary surgical options, facilitating or making sphincter-saving surgery possible

    The early of pelvic irradiation on the anal sphincter has not been previously investigated. This study prospectively evaluated the acute effect of preoperative radiation on anal function. Twenty patients with rectal carcinoma received 4,500 cGy of preoperative external beam radiation. The field of radiation included the sphincter in 10 patients and was delivered above the anorectal ring in 10 patients. Anal manometry and transrectal ultrasound were performed before and four weeks after radiotherapy. No significant difference in mean maximal squeeze or resting pressure was found after radiation therapy. An increase in mean minimal sensory threshold was significant. Histologic examination revealed minimal radiation changes at the distal margin in 8 of 10 patients who underwent low anterior resection and in 1 of 3 patients who underwent abdominoperineal resection. The authors conclude that preoperative radiation therapy has minimal immediate effect on the anal sphincter and is not a major contributing factor to postoperative incontinence in patients after sphincter-saving operations for rectal cancer

    Directory of Open Access Journals (Sweden)

    2013-03-01

    Full Text Available The integration and coordination of the musculature of the pelvic floor and the anal sphincters is critical to two important physiological functions: defecation and continence. Consequently, disorders affecting the pelvic floor muscles, the anal sphincters, their innervation or their precise coordination will, depending on their nature, result either in obstructed defecation or fecal incontinence. Both of these disorders are much more common in females and the latter, in particular, is linked with parity. While the symptomatology, presentation and optimal mode of investigation of fecal incontinence are well standardized, considerable debate and controversy continues to surround the contributions of pelvic floor and anal sphincter dysfunction to chronic constipation and the optimal clinical approach to their investigation remains to be defined. In appropriately chosen cases surgical intervention may provide the best outcome for sufferers from incontinence; biofeedback approaches may be of value in both incontinence and obstructed defecation and surgery has little role to play in the latter.

    2018-02-01

    Full Text Available Background: Vaginal delivery is the most important risk factors for development of faecal incontinence, which significantly affects quality of life. Foreign studies show OASIS occur at 20 to 40 % of vaginal deliveries. In Slovenia we recognize sphincter injuries at 1.7 % of deliveries, while true incidence of OASIS in our population remains unknown. Caesarean section prevents anal sphincter injuries. Known risk factors in foreign studies include prolonged second stage of labour, fetal weight > 3500 g, malpresentation, forceps delivery, maternal age more than 35 years at the time of first delivery, first delivery. Few women complain about defecatory problems in puerperium unless they are directly asked about them, so true incidence of such injuries is grossly underestimated. Previously compensated anal sphincter dysfunction can clinically manifest as late as in menopause. The most probable cause is atrophy of muscle and fibrous tissue of pelvic floor and anal sphincter due to lack of estrogen support in this period. With anal ultrasound we tried to determine the incidence of occult damage to anal sphincter in primiparas after vaginal delivery and the relation of injury to symptoms 6 weeks after delivery and identify possible risk factors in our population. We also tried to find out how many patients with anal sphincter injury become symptomatic immediately after deliv- ery. Methods: From January to June 2009 we examined 26 primiparas after vaginal delivery in the Ljubljana Maternity Hospital with anal ultrasound and compared various data about the delivery from our national delivery form. We excluded all patients with caesarean section, recognized anal sphincter injury at the time of the delivery or previous anorectal surgery, history of irritable bowel syndrome or pre-existing inflammatory bowel disease. All patients completed a bowel-function questionnaire, which included questions about faecal urgency and involuntary passing of gas, liquid or

    Between 0.5 and 5% of vaginal deliveries involve obstetrical anal sphincter injuries (OASIS). Thirty to forty percent of patients with OASIS will suffer from anal incontinence in the subacute postpartum period. The aim of the present study was to assess the effectiveness of early pelvic floor muscle training (PFMT) combined with standard rehabilitation on anal incontinence after vaginal deliveries complicated by OASIS. The present work was a retrospective quantitative study performed in a tertiary-level maternity hospital. Women with 3rd or 4th degree obstetric tears were included. Women who gave birth between January 1st, 2011 and December 31st, 2012 underwent standard pelvic-perineal rehabilitation within 6-8 weeks postpartum. Women who gave birth between January 1st, 2013 and July 1st, 2014 had early rehabilitation (within 30 days after delivery) followed by the same standard rehabilitation received by the other group. Rehabilitation was performed by physiotherapists specialized in perineology. No electrostimulation was done in early rehabilitation. An in-house-validated modification of the Jorge and Wexner questionnaire was sent by mail to the patients to assess symptoms. The main judgment criterion was anal incontinence to gas, loose stools and/or solid stool. Two hundred and thirty patients were diagnosed with OASIS. Nineteen women (8.3%) were lost to follow-up. The intention-to-treat analysis included 211 patients, 109 of whom underwent standard rehabilitation and 102 early rehabilitation plus standard rehabilitation. The two groups were comparable in terms of parity, birth weight, assisted delivery, epidural anesthesia and rates of mediolateral episiotomy. Multivariate analyses adjusted for type of perineal lesion were performed. Early rehabilitation significantly reduced gas leakage: OR 0.51 [0.29-0.90] (p=0.02), liquid stool leakage: OR 0.22 [0.08-0.58] (p=0.02) and urinary stress incontinence: OR 0.43 [0.24-0.77] (p=0.004).

    Temporary stool deviation, using a stoma, is a well-known surgical principle to protect low colorectal or coloanal anastomoses. The purpose of this study was to evaluate any morphologic changes with regard to the anal sphincter muscles during and after temporary ileostomy. Forty-four patients with rectal carcinomas were studied prospectively. All patients underwent low anterior resection. Reconstruction was performed using either a coloanal pouch or a straight end-to-end anastomosis. A protective stoma was fashioned in all 44 patients (ileostomy n=41; colostomy n=3). Stoma closure was carried out after a median of 85 days (41-330 days). Using a standard protocol, anal-sphincter thickness [m. puborectalis, external anal sphincter (EAS) and internal anal (IAS) sphincter] was assessed by means of endoanal ultrasonography preoperatively, at the time of stoma closure, and every 3 months thereafter for 1 year. The diameter of the puborectal muscle decreased from a median preoperative value of 6.3 mm to 5.7 mm at the time of stoma closure (P=0.03). After 3 months, 6.2 mm was measured. This value remained stable for the complete follow-up period. Similar results were recorded for the EAS. The IAS thickness remained stable throughout the study period, measuring between 2.1 mm and 2.4 mm. Temporary stool deviation does lead to morphologic changes of the anal sphincter. While the smooth muscle remains unchanged, the striated counterpart undergoes atrophic transformation. However, after passage reconstruction, i.e., stoma closure, a rapid regeneration of the voluntary muscles is observed.

    Background and purpose: preoperative radiochemotherapy (RCT) followed by curative surgery is a well-accepted therapeutic option in the treatment of advanced rectal cancer. Usually, the anal sphincter is located in the irradiation area of a preoperative RCT regime. The aim of this study is to evaluate the influence of preoperative RCT on anal sphincter function. Patients and methods: between 1994 and 2000, 102 patients with rectal cancer stage uT3/uT4 were analyzed. All patients underwent radiotherapy with 45 Gy (5 x 1.8 Gy) including two cycles of 5-fluorouracil (5-FU)/leucovorin (folinic acid) chemotherapy. 46 patients were treated additionally with up to five sessions of locoregional hyperthermia. The sphincter function was analyzed by perfusion manometry before preoperative therapy and 4 weeks after pretreatment had been finished. For statistics, the Wilcoxon signed rank test and mann-whitney U-test were used (SPSS 9.0 for Windows trademark). Results: the mean value of all 102 patients showed a significant reduction of the mean maximum resting pressure from 97 to 89 mmHg (p = 0.02). For the mean maximal squeeze pressure no significant difference could be shown (178 vs. 176 mmHg). For patients with distal (≤ 7.5 cm from anal verge) tumors the difference was highly significant (92 vs. 79 mmHg). Locoregional hyperthermia had no additional influence on sphincter function. Conclusion: preoperative RCT impairs sphincter function especially in patients with distal tumors. In addition, RCT could have a negative influence on the continence of patients who received sphincter-preserving surgery. (orig.) [de

    Artificial sphincters have been developed for patients with fecal incontinence, but finding a way to make such sphincters more "intelligent" remains a problem. We assessed the function of a novel intelligent artificial anal sphincter (IAAS) in vitro and in vivo in rabbits. After the prosthesis was activated, rabbits were continent of feces during 81.4% of the activation time. The fecal detection unit provided 100% correct signals on stool in vitro and 65.7% in vivo. The results indicated that the IAAS could efficiently maintain continence and detect stool; however, the IAAS is still in the preliminary experimental stage and more work is needed to improve the system. © 2011, Copyright the Authors.

    This paper reports on the electromagnetic effects on the biological tissue surrounding a transcutaneous transformer for an artificial anal sphincter. The coupling coils and human tissues, including the skin, fat, muscle, liver, and blood, were considered. Specific absorption rate (SAR) and current density were analyzed by a finite-length solenoid model. First, SAR and current density as a function of frequency (10–107 Hz) for an emission current of 1.5 A were calculated under different tissue thickness. Then relations between SAR, current density, and five types of tissues under each frequency were deduced. As a result, both the SAR and current density were below the basic restrictions of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The results show that the analysis of these data is very important for developing the artificial anal sphincter system. PMID:21121071

    This paper presents some of the latest progress in the development of a novel artificial anal sphincter system (AASS) to treat severe fecal incontinence. We have redesigned and integrated an intelligent, remote-controlled artificial anal sphincter based on biological signal feedback mechanisms. The device consists of an external telemetry unit, an internal artificial anal sphincter (IAAS), and a transcutaneous energy transfer system (TETS). The mechanical medical micropump of the IAAS can realize bidirectional flow with a maximum flow rate of 8.5 ml/min and can build backpressure up to 170 kPa. The design of the prosthesis reduces occlusion pressure and allows for low inflation volumes (9 mL-10.5 mL); operating pressures between 4.05 kPa and 7.16 kPa indicate that the risk of ischemic injury to the bowel is minimal. Furthermore, the rechargeable battery based on TETS puts the operation time at an estimated 2 days. The performance characteristics of the AASS and its efficiency in achieving continence and sensing the stool inside the anorectum were evaluated in vitro and in vivo in a pig model. Experimental results confirm that the system can maintain continence and build the sense of defecation successfully. Moreover, this innovation can be integrated into not only severe fecal incontinence, erectile dysfunction, and therapy-resistant reflux disease, but also morbid adiposity therapeutic AASS applications.

    The normal parameters of 3-dimensional endoanal ultrasound (3DEAUS) of the anal sphincter have not been reported for primigravidae or pregnant women at present. 3DEAUS parameters in Asian primigravidae were assessed in this study. We analyzed 3DEAUS data of 101 consecutives Asian primigravidae, assessed in the early third trimester. The assessment was performed with a rigid ultrasonic probe (Olympus ® RU 12M-R1 probe and EU-ME1 ultrasound system (Olympus Corp., Shinjuku, Japan). The Wilcoxon signed-rank test was used to detect the differences in pressure in different quadrants. The participants had a mean age of 24.7 (standard deviation [SD], 5.1) years. The Cleveland Clinic Incontinence Score was normal in all participants. The anal sphincter complex had 3 characteristic segments that were identifiable: upper, middle and lower. The puborectalis muscle was identified as a striated "V"-shaped sling, and its mean thickness was 7.44 (SD, 1.41) mm. The mean thickness of internal (IAS) and external (EAS) sphincters at the mid-sphincter level were 1.78 (SD, 0.59) and 5.49 (SD, 1.21) mm, respectively. The EAS measured 6.02 (SD, 1.07) mm at the lower sphincter level. The statistically significant differences seen in the in quadrants were: the IAS was thicker anteriorly (Z = -2.642; P = .008), the EAS at both midsphincter level (Z = -3.70; P IAS was thicker at the 9 o'clock position (Z = -2.081; P = .037). Good symmetry at all 3 levels was seen in the EAS (including the puborectalis muscle). Normal values of 3DEAUS for primigravidae have been identified and may serve as reference values for other laboratories. © 2018 by the American Institute of Ultrasound in Medicine.

    Twenty-two patients with full-thickness rectal prolapse underwent ambulatory fine wire electromyography of the internal and sphincter (IAS), external and sphincter and puborectalis, together with anorectal manometry, using a computerized system. Examinations were performed both before and 3 to 4 months after rectopexy. The median (interquartile range (i.q.r.)) preoperative IAS electromyogram (EMG) frequency was 0.18 (0.05-0.31) Hz and the median (i.q.r.) preoperative resting anal pressure was 28 (15-64) cmH2O. An improvement in the IAS EMG frequency, median (i.q.r.) 0.29 (0.19-0.38) Hz (P less than 0.03), and resting anal pressure, median (i.q.r.) 41 (20-72) cmH2O (P less than 0.05), was recorded after operation, but these variables remained significantly lower than those found in normal controls: median (i.q.r.) IAS EMG frequency 0.44 (0.36-0.48) Hz and median (i.q.r.) resting anal pressure 92 (74-98) cmH2O. We suggest that repair of the prolapse allows the IAS to recover by removing the cause of persistent rectoanal inhibition.

    Full Text Available A chronic anal fissure is a common painful perianal condition.The main operative procedure to treat this painful condition is a lateral internal sphincteretomy (LIS.The aim of study is to compare the outcome and complications of closed LIS up to the dentate line (whole length of internal sphincter or up to the fissure apex (partial length of internal sphincter in the treatment of anal fissure.It is a prospective comparativestudy including 100 patients with chronic fissure in ano. All patients assigned to undergo closed LIS. Those patients were randomly divided into two groups: 50 patients underwent LIS to the level of dentate line (whole length and other 50 patients underwent LIS to the level of fissure apex (partial length. Patients were followed up weekly in the 1st month, twice monthly in the second month then monthly   for next 2 months and finally after 1 year. There was satisfactory relief of pain in all patients in both groups & complete healing of the fissure occurred. Regarding post operative incontinence no major degree of incontinence occur in both group but minor degree of incontinence persists In 7 patients after whole length LIS after one year. In conclusion, both whole length & partial length LIS associated with improvement of pain, good chance of healing but whole length LIS associated with more chance of long term  flatus incontinence. Hence,we recommend partial length LIS as treatment forchronic anal fissure.

    To analyze the relationship between mean radiation dose to the bowels and the anal-sphincter and occurrence of 'defecation into clothing without forewarning', a specific and serious fecal incontinence symptom after gynecological radiotherapy. Additional potential risk factors associated with the symptom are explored. Data were collected for 519 eligible gynecological cancer survivors, treated with pelvic radiotherapy, with a median follow-up of 5.8 years, using a study-specific questionnaire and medical records. Correlations between defecation into clothing without forewarning and mean dose to organs at risk; the anal-sphincter region, the rectum, the sigmoid and the small intestines were investigated, also taking other risk factors into account. Twelve percent reported having had the symptom at least once in the preceding six months. Mean doses >50 Gy to the anal-sphincter region, the rectum, the sigmoid and the small intestines were related to the occurrence of the symptom. Significantly associated risk factors were deliveries with high birth weight, heart failure and lactose and/or gluten intolerance. After adjusting for these factors, mean doses >50 Gy to the anal-sphincter region, the sigmoid and the small intestines remained related to the occurrence of the symptom. Mean doses to the bowels and anal-sphincter region are related to the risk of defecation into clothing without forewarning in long-term gynecological cancer survivors treated with pelvic radiotherapy. Further radiobiological modeling may distinguish which organ(s) contribute most to development of the symptom.

    Full Text Available Introduction: Obstetric Anal Sphincter Injuries (OASIS has been reported in up to 25% patients and occult OASIS has been reported in up to 1.2%. Instrumental delivery has been considered a risk factor for OASIS. Aim: To compare the anal sphincter functions as assessed by Anorectal Manometry (ARM in asymptomatic patients following instrument delivery with those of patients who underwent Lower Segment Caesarian Section (LSCS after six months of delivery. Materials and Methods: Seventeen women who had instrumental delivery and thirteen who underwent elective cesarean section were recruited. Evaluation included a detailed history and physical examination, administration of the Cleveland Clinic Questionnaire and ARM to record the basal pressure, squeeze pressure, anorectal sensation and balloon expulsion time. Categorical variables were compared using the Chi-square test. All calculations were done using the software SPSS 21.0. Results: We found statistically significant lower basal (34 ± 3.4 vs 60±2.3 mm hg, p<0.05 and squeeze pressures (56±4.1 vs 76±5.2 mm hg, p<0.05, and higher balloon expulsion time (58±2.9 s vs 19±1.8 seconds, p<0.05 in women with instrument delivery compared to LSCS. The rectal sensation was comparable in both the groups. Conclusion: Persistent subtle anal sphincter dysfunctions are common following instrument delivery compared to LSCS. The role of identifying these and preventing future incontinence in such women needs to be assessed in future studies.

    A large proportion of age-related fecal incontinence is attributed to weakness or degeneration of the muscles composing the anal continence organ. However, the individual role of these muscles and their functional interplay remain poorly understood. This study employs a novel technique based on the combination of MR imaging and FLIP measurements (MR-FLIP) to obtain anatomical and mechanical information simultaneously. Unlike previous methods used to assess the mechanics of the continence organ, MR-FLIP allows inter-individual comparisons and statistical analysis of the sphincter morpho-mechanical parameters. The anatomy as well as voluntary and involuntary mechanical properties of the anal continence organ were characterized in 20 healthy senior volunteers. Results showed that the external anal sphincter (EAS) forms a funnel-like shape with wall thickness increasing by a factor of 2.5 from distal (6 ± 0 mm) to proximal (15 ± 3 mm). Both voluntary and involuntary mechanical properties in this region correlate strongly with the thickness of the muscle. The positions of least compliance and maximal orifice closing were both located toward the proximal EAS end. In addition, maximal contraction during squeeze maneuvers was reached after 2 s, but high muscle fatigue was measured during a 7 s holding phase, corresponding to about 60% loss of the energy produced by the muscles during the contraction phase. This work reports baseline parameters describing the morpho-mechanical condition of the sphincter muscle of healthy elderly volunteers. New parameters were also proposed to quantify the active properties of the muscles based on the mechanical energy associated with muscle contraction and fatigue. This information could be used to assess patients suffering from AI or for the design of novel implants. © 2018 John Wiley & Sons Ltd.

    Stem cells are an emerging treatment for regeneration of damaged anal sphincter tissues. Homing to the site of injury can be potentiated by stromal derived factor 1 (SDF-1) and monocyte chemotactic protein 3 (MCP-3) expression. The effects of electrical stimulation (ES) on upregulation of these cytokines were investigated. The anal sphincter complex of Sprague Dawley rats was stimulated with current of 0.25 mA, pulse duration of 40 pulses/s, pulse width of 100 μs, and frequency of 100 Hz for 1 or 4 h. Sham was created using the same needle which was inserted into the anal sphincter without electrical stimulation in different groups of animals. The rats were euthanized immediately or 24 h after stimulation. Cytokine analysis was performed using real-time polymerase chain reaction. Statistical analysis was performed. Results are presented as a fold increase compared to sham that was normalized to 1. SDF-1 and MCP-3 immediately after 1 h were 2.5 ± 0.77 and 3.1± 0.93 vs. sham, respectively, showing significant increase. After 1-h stimulation and euthanasia 24 h after, SDF-1 and MCP-3 were 1.49 ± 0.16 and 1.51± 0.14 vs. sham, respectively, showing significant increase. Immediately and 24 h after 4-h stimulation, SDF-1 was 1.21 ± 0.16 and 0.54 ± 0.16 vs. sham, respectively, and was not significantly different. Immediately and 24 h after 4-h stimulation, MCP-3 was 1.29 ± 0.41 and 0.35 ±1.0 vs. sham, respectively, and was not significantly different. SDF-1 and MCP-3 after 1 h were significantly higher than after 4 h of stimulation at both time points. Electrical stimulation for 1 h significantly upregulates SDF-1 and MCP-3 expression that persists for 24 h. Prolonged stimulation reduced chemokine expression, suggesting electrolysis of cells.

    Endoanal ultrasound (EAUS) is the gold standard for detecting anal sphincter defects in patients with faecal incontinence (FI), while anorectal manometry evaluates sphincter function. Three-dimensional high-resolution anorectal manometry (3D HRAM) is a newer modality with the potential to assess both sphincter function and anatomy. The purpose of the present study was to compare 3D HRAM with 3D EAUS for the detection of anal sphincter defects in patients with FI. A linkage analysis was performed between the 3D HRAM and 3D EAUS databases of a tertiary referral centre to identify patients with FI who underwent both 3D EAUS and 3D HRAM. With 3D HRAM, a defect was defined as any pressure measurement below 25 mmHg at rest with at least 18° of continuous expansion. The 3D HRAM findings were compared with those of 3D EAUS. The study cohort included 39 patients with a mean age of 64.7 ± 15.2 years (SD); and 31 (79%) were female. Eight (21%) patients had an anal sphincter defect on EAUS with a median size of 93° (range 40°-136°). Fourteen (36%) had a defect shown by 3D HRAM with a median size of 144° (36°-180°). The sensitivity, specificity and positive and negative predictive values of 3D HRAM in detecting a sphincter defect were 75%, 74%, 43% and 92%, respectively. With a negative predictive value of 92%, 3D HRAM may be a useful screening method for ruling out a sphincter defect in patients with FI, thereby avoiding both EAUS and manometry in selected patients.

    There is an increasing awareness of maternal somatic birth trauma, which affects many more women than previously thought, primarily in the form of anal sphincter and levator ani tears. Given that such trauma occurs in about one-third of all women giving birth vaginally for the first time, and given that it has serious long-term consequences, it should be audited by all maternity services with a view to providing remedial therapy to delay or prevent subsequent morbidity, and to facilitate practice improvement. The increasing availability of modern imaging equipment and the skills of using it for pelvic floor assessment means that it is now becoming possible to provide such services postnatally.

Data between the years 1999-2001 (era 1) when liberal mediolateral episiotomy was applied were compared with the years 2004-2008 (era 2) when restricted mediolateral episiotomy was implemented. Liberal mediolateral episiotomy was done for fetal or maternal indications, while restrictive mediolateral episiotomy was done when a tear was imminent. Primary outcome was the incidence of OAST. A total of 25,170 women who delivered vaginally were included. After adjusting for potential confounders, the incidence of OAST was found to be significantly higher in era 2 (0.4 %) compared to era 1 (0.1 %), (p = 0.02; adjusted OR 2.23; 95 % CI, 1.16-4.29). Among primiparous women, the incidence of mediolateral episiotomy was 71.8 and 27.1 % in eras 1 and 2, respectively (p liberal policy among primiparous women only, 124 deliveries are needed to prevent one OAST. Liberal compared to restrictive use of mediolateral episiotomy may be a sphincter-saving procedure among primiparous women.

  12. Radiological diagnosis in constipation and anal incontinence due to changes in the pelvic floor and sphincter apparatus of the anus

    International Nuclear Information System (INIS)

    Bistolfi, F.; Grillo Ruggeri, F.; Siragusa, A.

    1987-01-01

    Rectal constipation, anal incontinence and constipation combined with incontinence, are often caused by organic or simply functional changes in the pelvic floor and sphincterial apparatus. Therefore morphological as well as manometric and electromyographic studies of these anatomical parts are required. This is possible by combining two techniques: Intestinal Transit Time (ITT) and Defecatory Proctogram with Balloon (DPB). Personal experience of 38 patients with constipation with or without incontinence is reported. The results lead to the following conclusion: 1) ITT is a simple and non-invasive radiological technique that provides us with objective evidence of an impairment, i.e. constipation, whose symptoms are often only subjective; especially is allows us to identify rectal constipation, that can be caused by impairment of the anal sphincteral apparatus. 2) Using an uroprophylactic with a collar that adapts to the size of the anal duct, DPB always permits visualization of the duct with good representation of the recto-anal angle, whose changes may be the expression of organic or only functional impairments of the anal sphincterial apparatus. Increasing use of the two radiological techniques is therefore recommended in the diagnosis of alterations of the pelvic floor or anal sphincter

  13. Comparison of posterior internal anal sphincter myectomy and intrasphincteric botulinum toxin injection for treatment of internal anal sphincter achalasia: a meta-analysis.

    Friedmacher, Florian; Puri, Prem

    2012-08-01

    Internal anal sphincter (IAS) achalasia is a clinical condition with presentation similar to Hirschsprung's disease, but with the presence of ganglion cells on rectal suction biopsy (RSB). The diagnosis is made by anorectal manometry (ARM), which demonstrates the absence of the rectosphincteric reflex on rectal balloon inflation. The recommended treatment of choice is posterior IAS myectomy. Recently, intrasphincteric botulinum toxin (Botox) injection has been effectively used for treatment of IAS achalasia. The aim of this meta-analysis was to compare the efficacy of posterior IAS myectomy with intrasphincteric Botox injection for treatment of IAS achalasia. A systematic literature search for relevant articles was conducted using the following databases: MEDLINE( ® ), EMBASE(®), ISI Web of Science(SM) and the Cochrane Library. A meta-analysis was performed with the studies where IAS achalasia was diagnosed based on the results of ARM and RSB. Odds ratio (OR) with 95 % confidence intervals were calculated. Sixteen prospective and retrospective studies, published from 1973 to 2009, were identified. A total of 395 patients with IAS achalasia were included in this meta-analysis. Fifty-eight percent of patients underwent IAS myectomy and 42 % Botox injection. Regular bowel movements were significantly more frequent after IAS myectomy (OR 0.53, [95 % CI 0.29-0.99]; p = 0.04). There was no significant difference in continued use of laxatives or rectal enemas (OR 0.92, [95 % CI 0.34-2.53], p = 0.89) and in overall complication rates between both procedures (OR 0.68, [95 % CI 0.38-1.21]; p = 0.19). Looking at specific complications, the rate of transient faecal incontinence was significantly higher after Botox injection (OR 0.07, [95 % CI 0.01-0.54]; p IAS myectomy (OR 0.56, [95 % CI 0.32-0.97]; p = 0.04 and OR 0.25, [95 % CI 0.15-0.41]; p IAS achalasia, posterior IAS myectomy appears to be a more effective treatment option compared to intrasphincteric

    In this paper, a novel artificial anal sphincter (AAS) system based on rebuilding the rectal sensation function is proposed to treat human fecal incontinence. The executive mechanism of the traditional AAS system was redesigned and integrated for a simpler structure and better durability. The novel executive mechanism uses a sandwich structure to simulate the basic function of the natural human anal sphincter. To rebuild the lost rectal sensation function caused by fecal incontinence, we propose a novel method for rebuilding the rectal sensation function based on an Optimal Wavelet Packet Basis (OWPB) using the Davies-Bouldin (DB) index and a support vector machine (SVM). OWPB using a DB index is used for feature vector extraction, while a SVM is adopted for pattern recognition.Furthermore, an in vitro experiment with the AAS system based on rectal sensation function rebuilding was carried out. Experimental results indicate that the novel executive mechanism can simulate the basic function of the natural human anal sphincter, and the proposed method is quite effective for rebuilding rectal sensation in patients.

    For treating severe faecal incontinence, the authors developed an intelligent artificial anal sphincter system (AASS) equipped with a feedback sensor that utilized a transcutaneous energy transfer system (TETS). To deliver the correct amount of power (i.e. to match the load demand under variable coupling conditions caused by changes in positioning between the coils due to fitting and changes in posture), a regulating method to stabilize output voltage with a closed loop variable-frequency controller was developed in this paper. The method via which the voltage gain characteristics of a voltage-fed series-tuned TETS were derived is also described. The theoretical analysis was verified by the results of the experiment. A numerical analysis method was used as a control rule with respect to the relationship between operating frequency and output voltage. To validate the feedback control rules, a prototype of the TET charging system was constructed, and its performance was validated with the coupling variation between 0.12-0.42. The results show that the output voltage of the secondary side can be maintained at a constant 7 V across the whole coupling coefficient range, with a switching frequency regulation range of 271.4-320.5 kHz, and the proposed controller has reached a maximal end-to-end power efficiency of 67.5% at 1 W.

    Prostanoids, produced endogenously via cyclooxygenases (COXs), have been implicated in the sustained contraction of different smooth muscles. The two major types of COXs are COX-1 and COX-2. The COX subtype involved in the basal state of the internal anal sphincter (IAS) smooth muscle tone is not known. To identify the COX subtype, we examined the effect of COX-1- and COX-2-selective inhibitors, SC-560 and rofecoxib, respectively, on basal tone in the rat IAS. We also determined the effect of selective deletion of COX-1 and COX-2 genes (COX-1(-/-) and COX-2(-/-) mice) on basal tone in murine IAS. Our data show that SC-560 causes significantly more efficacious and potent concentration-dependent decreases in IAS tone than rofecoxib. In support of these data, significantly higher levels of COX-1 than COX-2 mRNA were found in the IAS. In addition, higher levels of COX-1 mRNA and protein were expressed in rat IAS than rectal smooth muscle. In wild-type mice, IAS tone was decreased 41.4 +/- 3.4% (mean +/- SE) by SC-560 (1 x 10(-5) M) and 5.4 +/- 2.2% by rofecoxib (P IAS from wild-type mice and significantly less (0.080 +/- 0.015 mN/mg) in the IAS from COX-1(-/-) mice (P IAS tone.

    This article presents a novel puborectalis muscle artificial anal sphincter system (PM-AASS) with the module of sensory perception for treating severe faecal incontinence (FI). Due to the implantable feature of PM-AASS, this system applied low-power design and the total energy consumption could drop to 48.8 Ah/d. To reduce the injury of intestine and the pressure exerted on intestine, the actuator, including the structure of tings and the robot mechanism, of PM-AASS was presented and the middle ring was optimised. To realise the sensory perception, the intestinal flexible pressure sensors, comprising the radial sensors and the axial sensors, were designed. The sensors calibration showed the R-square of each fitting line were above 0.998, which presented a high goodness of fit and indicated we could figure out the pressure value with the analogue voltage captured by MCU. Through the in-vitro experiment, the results that the radial sensors were more relevant to the occlusion threshold while the axial sensors had more effect on the alarm threshold could be concluded. The practicability of the PM-AASS was verified by the results of the in-vivo experiment, which showed that the PM-AASS had the effect of improvement to the anorectal internal pressure.

    To determine whether rates of obstetric anal sphincter injuries (OASIS) are continuing to increase and whether risk of OASIS according to mode of delivery is constant over time. In a retrospective population-based study, data were obtained for vaginal singleton vertex deliveries at 37-41 weeks of pregnancy among primiparous women in New South Wales, Australia, between January 2001 and December 2011. Annual OASIS rates were determined among non-instrumental, forceps, and vacuum deliveries with and without episiotomy. Multivariable logistic regression was used to determine adjusted odds ratios for each delivery mode category by year. Trends in adjusted odds ratios over time for each delivery category were compared. OASIS occurred in 955 (4.1%) of 23 081 deliveries in 2001 and 1487 (5.9%) of 25 081 deliveries in 2011. After adjustment for known risk factors, the only delivery categories to show statistically significant increases in OASIS over the study period were non-instrumental deliveries without episiotomy (linear trend Pdeliveries with episiotomy (linear trend P=0.004). Overall, OASIS rates have continued to increase. Known risk factors do not fully explain the increase in OASIS rates in non-instrumental deliveries without an episiotomy and in forceps deliveries with an episiotomy. Crown Copyright © 2015.

    Anorectal pressure studies have demonstrated internal anal sphincter (IAS) hypertonia in patients with chronic anal fissure. It is unknown however, if these changes in IAS function are associated with any abnormality in sphincter morphology. The first aim was to investigate the clinical characteristics and the manometric and endosonographic findings of the IAS in a cohort of patients with chronic anal fissure. The second aim was to investigate the association between these findings and the outcome with topical Glyceryl trinitrate (GTN) therapy. All patients who presented with chronic anal fissure from November 1999 to May 2004 were included after failure of conservative therapy. Anorectal manometry and anal endosonography were performed before treatment with 0.2% GTN ointment twice daily was initiated. Patients were evaluated after 8 weeks. One hundred and twenty-four patients (66 women, mean age, 45.2 +/- 14.8 years) were included. Hypertonia of the IAS was found in 84 (68%) patients. The mean maximum IAS thickness was 3.6 +/- 0.76 mm (1.6-5.5). An abnormally thick IAS, adjusted by age, was observed in 113 (91.1%) patients. We found no correlation between resting pressure and IAS thickness (r = 0.074; p = 0.41). At 8 weeks, 52 patients (42%) had healed with complete symptoms resolution. No statistically significant differences were observed when clinical features and manometric and endosonographic findings were compared between healing and no-healing fissures. The majority of patients with chronic anal fissure present an abnormally thick IAS. Clinical, manometric and endosonographic features had no association with outcome after GTN treatment.

    Full Text Available Abstract Background Early surgical results of anterior sphincter repair for faecal incontinence can be good, but in the longer term are often disappointing. This study aimed to determine the short and long term outcomes from anterior sphincter repair and identify factors predictive of long term success. Methods Patients who underwent anterior sphincter repair between 1989 and 2001 in one institution were identified. Postal questionnaires were sent to patients, which included validated scoring systems for symptom severity and quality of life assessments for faecal incontinence. Patient demographics and risk factors were recorded as were the results of anorectal physiology studies and endoanal ultrasound. Results Eighty-five patients underwent repair by one consultant. The length of follow up ranged from 1 to 12 years. Most patients (96% had early symptom improvement postoperatively. Of the 47 patients assessed long term (≥ 5 years, 28 (60% maintained this success. Significant improvements in quality of life were observed (P Conclusion There were no predictive factors of outcome success and no changes in anal manometry identified, however anterior sphincter repair remains worthwhile. Changes in compliance of the anorectum may be responsible for symptom improvement.

    The aim of this study was to investigate the efficacy of sacral neuromodulation (SNM) in the treatment of faecal incontinence and concomitant urinary incontinence in women with a history of obstetric anal sphincter injury (OASIS). In this prospective study, consecutive women with faecal incontinence following OASIS accepted for SNM were screened for concomitant urinary incontinence. The primary outcome was the change in urinary incontinence score on the International Consultation on Incontinence Questionnaire for Urinary Incontinence, Short Form (ICIQ-UI-SF), between baseline and 12 months. Secondary outcomes included the change in St Mark's score, sexual function and quality of life, change in grade of urinary incontinence and disappearance of urgency. From March 2012 to September 2014, 39 women with combined faecal incontinence and urinary incontinence received SNM. Thirty-seven women were available for analysis after 12 months. The mean reduction in the ICIQ-UI-SF score between the baseline and 12 months was 5.8 (95% CI 3.7-8.0, P < 0.001). ICIQ-UI-SF was reduced in 29 (78%) women, urinary incontinence resolved in 13/37 (35%, 95% CI 20%-50%) patients, and urgency disappeared in 14/33 (42%, 95% CI 26%-59%). The mean reduction in the St Mark's score was 10.6 (95% CI 8.6-12.7, P < 0.001). Disease-specific quality of life, Euroqual 5-dimension visual analogue scale (EQ-5D VAS) and several areas of sexual function changed significantly for the better. More than three-quarters of the women with combined faecal and urinary incontinence following OASIS reported a successful outcome with reduction in ICIQ-UI-SF at 12 months after SNM.

    To establish the prevalence of external (EAS) and internal anal sphincter (IAS) defects 15-24 years after childbirth in association to mode of delivery and faecal incontinence (FI), and compare the proportion of obstetric anal sphincter injuries (OASIS) reported at delivery with defects on ultrasound. This was a cross-sectional study including 563 women, who delivered their first child from 1990-97. Women responded to a validated questionnaire (PFDI) in 2013-14. The proportion of women with FI was recorded. Information about OASIS was obtained from the National Birth Registry. Study participants underwent 4D transperineal ultrasound examination. A defect of the EAS and IAS of ≥30° in ≥4/6 planes on tomographic ultrasound was registered. Multiple logistic regression was used to calculate adjusted odds ratios (aOR) for comparison of prevalence of EAS defects between different modes of delivery and in association to FI. Fisher's exact test was used for IAS defects. Defects of EAS and IAS were found after normal delivery (n = 201): 10% and 1%; forceps (n = 144): 32% and 7%; vacuum (n = 120): 15% and 4%, and no defects after caesarean section (n = 98). Forceps was associated with increased risk of EAS defects compared to normal delivery (aOR 4.1, 95% CI 2.3-7.2) and vacuum (aOR 3.0, 95% CI 1.6-5.6) and increased risk of IAS defects compared to normal delivery (cOR 7.4, 95% CI 1.5-70.5). The difference between vacuum and normal delivery was not significant. FI was indicated by 18% of women with EAS defects, 29% with IAS defects and 8% without sphincter defects. EAS and IAS defects were associated with increased risk of FI (aOR 2.5, 95% CI 1.3-4.9; cOR 4.2, 95% CI 1.1-13.5). 80% of ultrasonographical sphincter defects were not reported as OASIS at first or subsequent deliveries. Anal sphincter defects visualized by transperineal ultrasound 15-24 years after delivery were associated with forceps and FI. Undetected OASIS was frequent. This article is

    Bone marrow mesenchymal stem cells (BMSCs) and acupuncture are known to mitigate tissue damage. This study aimed to investigate the therapeutic effects of combined electroacupuncture (EA) stimulation and BMSC injection in a rat model of anal sphincter injury-induced faecal incontinence (FI). 60 Sprague-Dawley rats were randomly divided into five groups: sham-operated control, FI, FI+EA, FI+BMSC, and FI+BMSC+EA. The anorectal tissues were collected on days 1, 3, 7 and 14. Repair of the injured anal sphincter was compared using haematoxylin and eosin (HE) and immunocytochemiscal analyses with sarcomeric α actinin. The expression of stromal cell derived factor-1 (SDF-1) and monocyte chemoattractant protein-3 (MCP-3) was detected by quantitative reverse transcription PCR to evaluate the effects of EA on the homing of BMSCs. The therapeutic effect of combined EA+BMSCs on damaged tissue was the strongest among all the groups as indicated by HE and immunohistochemical staining. The expression of SDF-1 and MCP-3 was significantly increased by combined EA and BMSC treatment when compared with the other groups (P=0.01 to P<0.05), suggesting promotive effects of EA on the homing of BMSCs. The combination of EA and BMSC transplantation effectively repaired the impaired anal sphincters. The underlying mechanism might be associated with apparent promotive effects of EA on the homing of BMSCs. Our study provides a theoretical basis for the development of a non-surgical treatment method for FI secondary to muscle impairment. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To investigate the recurrence risk, the likelihood of having further deliveries and mode of delivery after third to fourth degree obstetric anal sphincter injuries (OASIS). Population-based cohort study. The Medical Birth Registry of Norway. A cohort of 828,864 mothers with singleton, vertex-presenting infants, weighing 500 g or more, during the period 1967-2004. Comparison of women with and without a history of OASIS with respect to the occurrence of OASIS, subsequent delivery rate and planned caesarean rate. OASIS in second and third deliveries, subsequent delivery rate and mode of delivery. Adjusted odds ratios of the recurrence of OASIS in women with a history of OASIS in the first, and in both the first and second deliveries, were 4.2 (95% CI 3.9-4.5; 5.6%) and 10.6 (95% CI 6.2-18.1; 9.5%), respectively, relative to women without a history of OASIS. Instrumental deliveries, in particular forceps deliveries, birthweights of 3500 g or more and large maternity units were associated with a recurrence of OASIS. Instrumental delivery did not further increase the excess recurrence risk associated with high birthweight. A man who fathered a child whose delivery was complicated by OASIS was more likely to father another child whose delivery was complicated by OASIS in another woman who gave birth in the same maternity unit (adjusted OR 2.1; 95% CI 1.2-3.7; 5.6%). However, if the deliveries took place in different maternity units, the recurrence risk was not significantly increased (OR 1.3; 95% CI 0.8-2.1; 4.4%). The subsequent delivery rate was not different in women with and without previous OASIS, whereas women with a previous OASIS were more often scheduled to caesarean delivery. Recurrence risks in second and third deliveries were high. A history of OASIS had little or no impact on the rates of subsequent deliveries. Women with previous OASIS were delivered more frequently by planned caesarean delivery. © 2011 The Authors BJOG An International Journal of

    The aim of this study was to optimize an intelligent artificial anal sphincter system (AASS) II for patients with severe fecal incontinence. Redesigning and integrating a pressure sensor into the sphincter prosthesis allows us to reduce the sensor volume and makes it suitable for a chronic, ambulatory application. Furthermore, a close-loop frequency control method was designed for the transcutaneous energy transfer system. Finally, a longer working time of the implanted device was obtained by the low-power design of the hardware and software. The new model was implanted in 2 dogs and studied for periods of up to 5 weeks. The output voltage induced on the load of 30 Ω, for a variation range in k of 0.12 ~ 0.42, was maintained at approximately 6.8 V with a frequency control range of the 270 ~ 320 kHz. The minimum and maximum output voltages of the pressure sensor were found to be 1.7 V and 2.34 V, respectively, which corresponded to a pressure range of 90 ~ 120 kPa with maximum change rate of approximately 3.7% caused by the temperature variations. Moreover, compared with AASS I, the low-power design resulting in 94% reduction in power consumption. The efficacy of the device in achieving continence and sensing the need to defecate was assessed in an animal model. The technical concept and the design of the AASS II turned out to be capable of fulfilling the medical requirements.

    Intersphincteric resection has become a widely used treatment for patients with rectal cancer. However, the detailed anatomy of the anal canal related to this procedure has remained unclear. The purpose of this study was to clarify the detailed anatomy of the anal canal. This is a descriptive study. Histologic evaluations of paraffin-embedded tissue specimens were conducted at a tertiary referral hospital. Tissue specimens were obtained from cadavers of 5 adults and from 13 patients who underwent abdominoperineal resection for rectal cancer. Sagittal sections from 9 circumferential portions of the cadaveric anal canal (histologic staining) and 3 circumferential portions from patients were studied (immunohistochemistry for smooth and skeletal muscle fibers). Longitudinal fibers between the internal and external anal sphincters consisted primarily of smooth muscle fibers that continued from the longitudinal muscle of the rectum. The levator ani muscle attached directly to the lateral surface of the longitudinal smooth muscle of the rectum. The length of the attachment was longer in the anterolateral portion and shorter in the posterior portion of the anal canal. In the lateral and posterior portions, the levator ani muscle partially overlapped the external anal sphincter; however, there was less overlap in the anterolateral portion. In the posterior portion, thick smooth muscle was present on the surface of the levator ani muscle and it continued to the longitudinal muscle of the rectum. We observed only limited portions in some surgical specimens because of obstruction by tumors. The levator ani muscle attaches directly to the longitudinal muscle of the rectum. The spatial relationship between the smooth and skeletal muscles differed in different portions of the anal canal. For intersphincteric resection, dissection must be performed between the longitudinal muscle of the rectum and the levator ani muscle/external anal sphincter, and the appropriate surgical lines

    Intra-operative neuromonitoring is increasingly applied in several surgical disciplines and has been introduced to facilitate pelvic autonomic nerve preservation. Nevertheless, it has been considered a questionable tool for the minimization of risk, as the results are variable and might be misleading. The aim of the present experimental study was to develop an intra-operative neuromonitoring system with improved reliability for monitoring pelvic autonomic nerve function. Fifteen pigs underwent low anterior rectal resection with pelvic autonomic nerve preservation. Intra-operative neuromonitoring was performed under autonomic nerve stimulation with observation of electromyographic signals of the internal anal sphincter and bladder manometry. As the internal anal sphincter frequency spectrum during stimulation was found to be mainly in the range of 5-20 Hz, intra-operative neuromonitoring signals were postoperatively processed by implementation of matching band pass filters. In 10 preliminary experiments, signal processing was performed offline in the postoperative analysis. Of 163 stimulations intra-operatively assessed by the surgeon as positive responses, 135 (83%) were confirmed after signal processing. In the following five consecutive experiments intra-operative online signal processing was realized and demonstrated reliable intra-operative neuromonitoring signals of internal anal sphincter activity with significant increase during pelvic autonomic nerve stimulation [0.5 μV (interquartile range = 0.3-0.7) vs 4.8 μV (interquartile range = 2.5-7.5); P signal processing of internal anal sphincter activity aids reliable identification of pelvic autonomic nerves with potential for improvement of intra-operative neuromonitoring in pelvic surgery. © 2011 The Authors.

    Wnt-β catenin is an important signaling pathway in the genesis of fibrosis in many organ systems. Our goal was to examine the role of Wnt pathway in the external anal sphincter (EAS) injury-related fibrosis and muscle dysfunction. New Zealand White female rabbits were subjected to surgical EAS myotomy and administered local injections of either a Wnt antagonist (sFRP-2; daily for 7 days) or saline. Anal canal pressure and EAS length-tension (L-T) were measured for 15 weeks after which the animals were sacrificed. Anal canal was harvested and processed for histochemical studies (Masson trichrome stain), molecular markers of fibrosis (collagen and transforming growth factor-β) and immunostaining for β catenin. Surgical myotomy of the EAS resulted in significant impairment in anal canal pressure and EAS muscle L-T function. Following myotomy, the EAS muscle was replaced with fibrous tissue. Immunostaining revealed β catenin activation and molecular studies revealed 1.5-2 fold increase in the levels of markers of fibrosis. Local injection of sFRP-2 attenuated the β catenin activation and fibrosis. EAS muscle content and function was significantly improved following sFRP-2 treatment. Our studies suggest that upregulation of Wnt signaling is an important molecular mechanism of injury related EAS muscle fibrosis and sphincter dysfunction.

    Our primary objective was to prospectively evaluate anorectal symptoms, anal manometry and endoanal ultrasound (EAUS) in women who followed the recommended mode of subsequent delivery following index obstetric anal sphincter injuries (OASIs) using our unit's standardised protocol. Our secondary objectives were to evaluate the role of internal anal sphincter defects and also to compare outcomes in a subgroup of symptomatic women with normal anorectal physiology. This is a prospective follow-up study of pregnant women with previous OASIs who were counselled regarding subsequent mode of delivery between January 2003 and December 2014. Assessment involved the St Mark's Incontinence Score (SMIS), anal manometry and EAUS at both antepartum and 3-month postpartum visits. Data were analysed using Wilcoxon and Mann-Whitney U tests. Three hundred and fifty women attended the perineal clinic over the study period, of whom 122 met the inclusion criteria (99 vaginal delivery [VD], 23 caesarean section). No significant worsening of anorectal symptoms was observed following subsequent delivery in the VD group (p = 0.896), although a reduced squeeze pressure was observed at 3 months postpartum (p delivery. In the absence of a randomised study, use of this protocol can aid clinicians in their decision-making.

    The aim of this study was to compare functional and quality of life data in patients with increasing grades of obstetric anal sphincter injury (OASI) presenting to a tertiary colorectal pelvic floor clinic within 24 months of delivery. Prospective data were collected from the patients for the period 2009-2016 and included data on functional outcomes and motor anorectal manometry parameters. The instruments used for the evaluation of functional outcomes were the Birmingham Bowel and Urinary Symptoms Questionnaire, the Wexner Incontinence Score, Short Form 36, and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire. OASI grade of injury was based on the postdelivery endoanal ultrasound scan. Data from patients with a grade 3a, 3b, 3c or 4 OASI were compared using one-way ANOVA for parametric data and the Kruskal-Wallis test for nonparametric data overall and for separate time periods (3-6 months, 6-12 months, 12-24 months). Functional patient data were available in 177 patients: 29 with grade 3a, 55 with grade 3b, 77 with grade 3c and 16 with grade 4 OASI. There was no discernible trend in worsening function with increasing severity of OASI overall, nor for the specified time periods of 3-6 months 58 patients), 6-12 months (85 patients) or 12-24 months (18 patients). Our series demonstrated no significant differences in functional outcomes or quality of life in patients with different OASI grades. Longer-term follow-up is required to ascertain any later functional differences which may become apparent with time.

    Obstetric anal sphincter injury (OASI) is a rare but serious outcome of vaginal birth. Based on concerns about the increasing number of women who commence childbearing later than previous generation, this study aimed at investigating age-related risk of OASI in women of different parity. A population-based register study including 959,559 live singleton vaginal births recorded in the Swedish Medical Birth Register 1999 to 2011. In each parity group risks of OASI at age 25-29 years, 30-34 years, and ≥35 years compared with age birth, education, region of birth, smoking, Body Mass Index, infant birthweight and fetal presentation; and in parous women, history of OASI and cesarean section. Additional analyses also adjusted for mediating factors, such as epidural analgesia, episiotomy, and instrumental delivery, and maternal age-related morbidity. Rates of OASI were 6.6%, 2.3% and 0.9% in first, second and third births respectively. Age-related risk increased from 25-29 years in first births (Adjusted OR 1.66; 95% CI 1.59-1.72) and second births (Adjusted OR 1.78; 95% CI 1.58-2.01), and from 30-34 years in third births (Adjusted OR 1.60; 95% CI 1.00-2.56). In all parity groups the risk was doubled at age ≥ 35 years, compared with the respective reference group of women under 25 years. Adding mediating factors and maternal age-related morbidity only marginally reduced these risk estimates. Maternal age is an independent risk factor for OASI in first, second and third births. Although age-related risks by parity are relatively similar, more nulliparous than parous women will be exposed to OASI due to the higher baseline rate.

    The purpose of this trial was to compare the effectiveness of sacral neuromodulation (SNM) with a submucosal injection of collagen (Permacol®) in women with faecal incontinence following obstetric anal sphincter injury (OASIS). This single-blinded randomized controlled trial at two hospital units in Norway included women with faecal incontinence following OASIS. Eligible women who had had a successful percutaneous nerve evaluation were randomly assigned to SNM or Permacol®. The primary outcome was the difference in the St Mark's incontinence score between baseline and 6 months. Secondary outcomes were changes in the disease-specific quality of life (FIQL) and urinary incontinence (ICIQ-UI-SF) scores. Fifty-eight women were randomly assigned to SNM (n = 30) and Permacol® (n = 28). The reduction in the St Mark's score between baseline and 6 months was 11.2 (SD 5.3) in the SNM group vs 2.3 (SD 5.0) in the Permacol® group, resulting in a difference of 8.9 (95% CI: 6.1-11.7, P < 0.0001). The differences in the four scales of FIQL (lifestyle, coping, depression, embarrassment) were 0.90 (95% CI: 0.50-1.30, P < 0.001), 1.05 (0.62-1.47, P < 0.001), 0.52 (95% CI: 0.16-0.87, P = 0.005) and 0.95 (95% CI: 0.50-1.40, P < 0.001), respectively, in favour of SNM. The difference in the ICIQ-UI-SF was 5.0 (95% CI: 1.97-8.02, P = 0.002) in favour of SNM. There were nine minor adverse events in the SNM group compared with seven in the Permacol® group (P = 0.77). SNM was superior to Permacol® in terms of reduction of St Mark's score, ICIQ-UI-SF and the change of the FIQL in women with faecal incontinence following OASIS.

    Biofeedback therapy (BFT) is an established treatment for fecal incontinence (FI), with access often being restricted to tertiary centers due to resources and the perceived requirement for high-intensity regimes. However, the optimal regime remains unknown. We evaluated outcomes from our low-intensity integrated BFT program in a secondary care center. Outcomes of our BFT service for FI were evaluated retrospectively. Response was defined by ≥50% improvement in FI frequency from baseline or complete continence. Responders were compared to non-responders for factors including symptoms, manometry data, sphincter exercise technique and duration of practice, and the number and frequency of sessions. Where patients dropped out, outcomes and the reason for dropout were obtained retrospectively. Fecal incontinence patients (n=205, median 62 years, 72% female) attended a median (IQR) 3 (2) BFT sessions with 55 (36) days between visits. Overall, 146/205 (71%) responded with 97/205 (47%) achieving continence. Fecal incontinence frequency improved dramatically in completed cases (P=0.000). While non-response was associated with males (P=0.03) and dropout (P=0.000), "good" anal sphincter exercise technique (P=0.008) and longer in-home practice (P=0.007) and more sessions (P=0.04) were associated with response. Dropout rate was 80/205 (39%), with the reason for dropout being obtained in 80%. Despite low-intensity BFT, comparable outcomes to data from tertiary centers were achieved. Our data emphasize the importance of technique and in-home practice of anal sphincter exercises. Customizing BFT intensity based on predictive factors and encouraging in-home practice may optimize outcomes, reduce dropout rates, and rationalize resources. © 2016 John Wiley & Sons Ltd.

    The internal anal sphincter (IAS) plays an important role in maintaining continence and a number of neurotransmitters are known to regulate IAS tone. The aim of this study was to determine the relative importance of the neurotransmitters involved in the relaxant and contractile responses of the porcine IAS. Responses of isolated strips of IAS to electrical field stimulation (EFS) were obtained in the absence and presence of inhibitors of neurotransmitter systems. Contractile responses of the sphincter to EFS were unaffected by the muscarinic receptor antagonist, atropine (1 μM), but were almost completely abolished by the adrenergic neuron blocker guanethidine (10 μM). Contractile responses were also reduced (by 45% at 5 Hz, P synthesis (40-50% reduction), zinc protoprophyrin IX (10 μM), an inhibitor of carbon monoxide synthesis (20-40% reduction), and also propargylglycine (30 μM) and aminooxyacetic acid (30 μM), inhibitors of hydrogen sulphide synthesis (15-20% reduction). Stimulation of IAS efferent nerves releases excitatory and inhibitory neurotransmitters: noradrenaline is the predominant contractile transmitter with a smaller component from ATP, whilst 3 gases mediate relaxation responses to EFS, with the combined contributions being nitric oxide > carbon monoxide > hydrogen sulfide.

    The aim of this study was to assess long-term pelvic floor symptoms after an obstetric anal sphincter injury (OASI). This retrospective cohort study included 237 cases of OASI (0.86% of deliveries) identified at Poitiers University Hospital between 2000 and 2011. Symptoms were assessed using validated self-administered questionnaires, including Female Pelvic Floor Questionnaire, Pescatori anal incontinence score, EuroQoL five-dimension score, and pain visual analogue scale (VAS). One hundred and sixty women (67%) filled out the questionnaires, on average 46 months after delivery (8-152). Among them, 93 (54%) reported at least one symptom occurring "frequently" (the most common being dyspareunia), and 45 (28%) a symptom occurring "daily" (the most common being flatus incontinence). Anal incontinence was reported by 32 (20%) women, flatus incontinence "frequently" or "daily" by 28 (18%), and stool incontinence "frequently" or "daily" by 9 (6%). Urinary incontinence was reported "frequently" or "daily" by 27 women (17%) at stress, 17 (11%) at urge, and 11 (7%) at mixed circumstances. Prolapse symptoms were reported "frequently" or "daily" by 6 women (4%). Pain during intercourse was reported "frequently" or "daily" by 17 women (11%). Twenty-four women (18%) reported chronic pelvic pain (VAS score≥4/10). Ninety-five percent of women reported a normal quality of life for mobility, self-care, and usual activities; however, alterations in pain/discomfort (32%) and anxiety/depression (33%) domains were frequently reported. Pelvic floor symptoms 4 years after OASI were highly prevalent. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Tobacco smoking can cause vascular injury, tissue hypoxia and fibrosis as can ionizing radiation. However, we do not know if tobacco smoking increases the risk of long-term side effects after radiotherapy for prostate cancer. We identified 985 men treated with radiotherapy for prostate cancer between 1993 and 2006. In 2008, long-lasting symptoms appearing after radiotherapy for prostate cancer were assessed through a study-specific questionnaire as were smoking habits and demographic factors of all these men. In the questionnaire the prostate-cancer survivors were asked to report symptom occurrence the previous six months. We obtained information on tobacco smoking from 836 of the 985 prostate-cancer survivors with a median time to follow-up of six years (range 2-14 years). The prevalence ratio of defecation urgency among current smokers compared to never smokers was 1.6 (95% CI 1.2-2.2). Corresponding prevalence ratio for diarrhea was 2.8 (95% CI 1.2-6.5), the sensation of bowel not completely emptied after defecation 2.1 (95% CI 1.3-3.3) and for sudden emptying of all stools into clothing without forewarning 4.7 (95% CI 2.3-9.7). Tobacco smoking among prostate-cancer survivors treated with radiotherapy increases the risk of certain long-lasting symptoms from the bowel and anal-sphincter region.

    organism. It presents with an ample specter of physiological actions being the most important its mechanism of action in the relaxation of the smooth musculature, its neurotransmissor activity in some systems and its involvement in the inflammatory process. The NO is synthesized in different tissues by the conversion of the L-arginine in L-citruline with the action of the enzyme nitric oxide sintase(NOS. OBJECTIVES: the aim of this study is to demonstrate the involvement of nitric oxide in the inflammatory intestinal process of Wistar rats submitted to experimental colitis with ascetic acid. MATERIAL AND METHODS: 20 male Wistar rats had been used with weight between 250 and 350 g divided in two groups of 10 animals. The animals of the group in study had been submitted to intracolonic administration, by enema, of a solution with acid ascetic diluted to 7% - 3 ml. The control group received only enema with saline solution. The histological scores, the expression of the enzyme nitric oxide sintase (iNOS and the sphincteric anal pressure had been evaluated. RESULTS: The histological scores had presented a significant rise in the group colitis when compared with the control group in the macroscopic as well as in the microscopical evaluation. The expression of the enzyme iNOS was also significantly higher in the colitis group when compared to the control group. The sphincteric anal pressure was significantly lower in the group colitis when compared to control group. CONCLUSION: The animals submitted to the experimental colitis presented an increase of the iNOS expression. This increase, associated with the consequent increase in nitric oxide level, causes a reduction of the sphincteric anal pressure levels.

    There is no standard of care for women sustaining an obstetric anal sphincter injury (OASIS). We sought to determine whether pelvic floor physical therapy (PFPT) would improve the quality of life and function in women 12 weeks after OASIS. This institutional review board-approved randomized trial enrolled primiparous women 2 weeks after delivery complicated by OASIS. After informed consent, all subjects underwent vaginal electromyography and anorectal manometry and completed validated questionnaires; measures were repeated for all subjects at 12 weeks after delivery. The intervention arm completed 4 PFPT sessions. The primary outcome was a change in the Fecal Incontinence Quality of Life. Three hundred four women were screened; 250 were excluded, and 54 were randomized. After four were lost to follow-up, analysis included 27 in the intervention arm and 23 in the control arm. Overall, mean age was 29.8 ± 4.7 years, and there were no demographic differences between groups.Fecal Incontinence Quality of Life domain scores showed improvement for both groups from baseline to 12 weeks for coping (P = 0.006) and depression (P = 0.009); however, there was no difference in domain scores between groups. For the secondary outcome of anorectal manometry, squeezing pressure improved for all subjects (P = 0.035) from baseline to 12 weeks. Vaginal EMG strength (microvolts) increased for all subjects in measures of rest average (P < 0.000), rapid peak (P = 0.006), and work average (P < 0.000), with no difference based on therapeutic arm. All women showed improvements in quality of life and function at 12 weeks after delivery, regardless of treatment allocation. Further study is needed to determine whether PFPT provides a significant benefit to women having OASIS.

    Obstetric anal sphincter injuries (OASIS) are associated with an increased risk of faecal incontinence after vaginal delivery. The aim of this retrospective population-based cohort study was to assess whether mediolateral episiotomy is associated with a reduction in the rate of OASIS during operative vaginal delivery. We used data from the Dutch Perinatal Registry (Perined) that includes records of almost all births between 2000 and 2010 in The Netherlands. In a cohort of 170,969 primiparous and multiparous women whose delivery was recorded, we estimated the association between mediolateral episiotomy and OASIS following both vacuum and forceps deliveries using univariate and multivariate logistic regression analysis. The incidences of OASIS following vacuum delivery in 130,157 primiparous women were 2.5% and 14% in those with and without a mediolateral episiotomy, respectively (adjusted OR 0.14, 95% CI 0.13-0.15), and in 29,183 multiparous women were 2.0% and 7.5%, respectively (adjusted OR 0.23, 95% CI 0.21-0.27). The incidences of OASIS following forceps delivery in 9,855 primiparous women were 3.4% and 26.7% in those with and without a mediolateral episiotomy, respectively (adjusted OR 0.09, 95% CI 0.07-0.11), and in 1,774 multiparous women were 2.6% and 14.2%, respectively (adjusted OR 0.13, 95% CI 0.08-0.22). The use of a mediolateral episiotomy during both vacuum delivery and forceps delivery is associated with a fivefold to tenfold reduction in the rate of OASIS in primiparous and multiparous women.

    This study evaluated the 4-year results of 32 patients with T1N0 low-lying rectal adenocarcinoma treated solely with californium-252 (Cf-252) neutron intracavity brachytherapy (ICBT). Patients were solicited into the study from January 2008 to June 2011. All the patients had refused surgery or surgery was contraindicated. The patients were treated with Cf-252 neutron ICBT using a novel 3.5-cm diameter off-axis 4-channel intrarectal applicator designed by the authors. The dose reference point was defined on the mucosa surface, with a total dose of 55-62 Gy-eq/4 f (13-16 Gy-eq/f/wk). All the patients completed the radiotherapy in accordance with our protocol. The rectal lesions regressed completely, and the acute rectal toxicity was mild (≤G2). The 4-year local control, overall survival, disease-free survival, and late complication (≥G2) rates were 96.9%, 90.6%, 87.5% and 15.6%, respectively. No severe late complication (≥G3) occurred. The mean follow-up was 56.1 ± 16.0 months. At the end of last follow-up, 29 patients remained alive. The mean survival time was 82.1 ± 2.7 months. Cf-252 neutron ICBT administered as the sole treatment (without surgery) for patients with T1N0 low-lying rectal adenocarcinoma is effective with acceptable late complications. Our study and method offers a definitive anal sphincter-preserving radiotherapy for T1N0 low-lying rectal adenocarcinoma patients.

    A comprehensive genomic and proteomic, computational, and physiological approach was employed to examine the (previously unexplored) role of microRNAs (miRNAs) as regulators of internal anal sphincter (IAS) smooth muscle contractile phenotype and basal tone. miRNA profiling, genome-wide expression, validation, and network analyses were employed to assess changes in mRNA and miRNA expression in IAS smooth muscles from young vs. aging rats. Multiple miRNAs, including rno-miR-1, rno-miR-340-5p, rno-miR-185, rno-miR-199a-3p, rno-miR-200c, rno-miR-200b, rno-miR-31, rno-miR-133a, and rno-miR-206, were found to be upregulated in aging IAS. qPCR confirmed the upregulated expression of these miRNAs and downregulation of multiple, predicted targets (Eln, Col3a1, Col1a1, Zeb2, Myocd, Srf, Smad1, Smad2, Rhoa/Rock2, Fn1, Tagln v2, Klf4, and Acta2) involved in regulation of smooth muscle contractility. Subsequent studies demonstrated an aging-associated increase in the expression of miR-133a, corresponding decreases in RhoA, ROCK2, MYOCD, SRF, and SM22α protein expression, RhoA-signaling, and a decrease in basal and agonist [U-46619 (thromboxane A 2 analog)]-induced increase in the IAS tone. Moreover, in vitro transfection of miR-133a caused a dose-dependent increase of IAS tone in strips, which was reversed by anti-miR-133a. Last, in vivo perianal injection of anti-miR-133a reversed the loss of IAS tone associated with age. This work establishes the important regulatory effect of miRNA-133a on basal and agonist-stimulated IAS tone. Moreover, reversal of age-associated loss of tone via anti-miR delivery strongly implicates miR dysregulation as a causal factor in the aging-associated decrease in IAS tone and suggests that miR-133a is a feasible therapeutic target in aging-associated rectoanal incontinence.

  16. Similar mechanisms of traumatic rectal injuries in patients who had anal sex with animals to those who were butt-fisted by human sexual partner.

    Sexual pleasure comes in various forms of physical play, for many it involves stimulation of the vagina, while the anus for others; some enjoy both. A recent report by Cappelletti et al. 1 shows a meta-analysis of cases describing anal trauma due to sexual fisting in human partners. This clinical article reports four cases of males diagnosed with zoophilia, and who received anal sex from animals, resulting in injuries. Surgical and psychiatric evaluations are summarized. Unusual etiology of sexual activity with animals caused peri-anal trauma in men who engaged in anal sex with dogs and farm animals. Injuries to patients who receive anal sex from animals are mechanistically similar to fisting-induced rectal damage. Among zoophiles, the mode of harm occurs through blood-engorged, interlocked penis that causes tissue lacerations upon retraction from an anus. In people experimenting with fisting, repetitive stretching within anal canal and of external sphincter causes the internal injuries. The mode of physical stimulation explains the extent of injuries in fisters vs. zoophiles: in fisting, the pressure applied by hand is controllable proximally around and within anal sphincter, while penetration by the animal penis is unpredictable and occurs within the proximal anal canal. Forensically, the findings presented in this article describe a significant mechanism of injury in fisters versus passive zoophiles. These descriptions may aid in clinically differentiating pleasurable and pathological rectal stimulation. Copyright © 2017 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

    (78% para incontinência fecal. Embora a pressão máxima de contração voluntária não indique falso-positivos, apresenta 72% de falso-negativos. A probabilidade deste fato acontecer com a medida de capacidade de sustentação da pressão de contração voluntária é, praticamente, 20% menor, valor estatisticamente significativo. CONCLUSÃO: O indicativo de função esfincteriana é melhor analisado pela capacidade de sustentação. A capacidade de sustentação traduz com mais exatidão, a capacidade funcional do canal anal em relação à continência voluntária, sendo isoladamente, melhor que a pressão máxima de contração voluntária.BACKGROUND: It has been demonstrated that the maximum squeeze pressure and the mean resting pressure do not reflect the true clinical situation of patients having fecal incontinence, as well as the functional status of the anal canal. Furthermore, a wrong diagnosis could be obtained and therefore misleading to a not effective treatment. AIM: Under the hypothesis that squeezing and sustaining the anal canal contraction is more important than the maximum squeeze pressure, the capacity to sustain the squeeze pressure of the anal canal was analyzed aiming to quantify the sphincteric function. METHODS: Seventy-two patients having fecal incontinence in different degrees (56 female and 15 normal individuals (9 female were submitted to anorectal manometry to measure the mean resting pressure, the maximum voluntary squeeze pressure and the capacity to sustain the squeeze pressure. RESULTS: Normal individuals had normal values of mean resting pressure and maximum squeeze pressure, and adequate capacity to sustain the squeeze pressure of the canal anal. Incontinent patients had mean resting pressure and maximum squeeze pressure with normal or below normal pressoric values and similar profile of capacity to sustain which was moderate in the initial phase and worse in the intermediate and final phases, with decreasing of the capacity to

    Correlations between anal sphincter function as assessed by anorectal manometry and anal sphincter anatomy measured by endoluminal ultrasound have been reported in the literature both for patients and for healthy individuals but have not been confirmed by other authors. For a larger series of patients (152 consecutive patients, mean age 54.1 +/- 15.5 years; female:male ratio, 111:41) with anorectal dysfunctions such as incontinence (n = 92), constipation (n = 37), and other symptoms (n = 23), diagnostic work-up included conventional multilumen anorectal manometry to evaluate internal sphincter pressure at rest, maximum external sphincter squeeze pressure during contraction, and endoanal sonography to determine anal sphincter integrity and to measure dorsal, left lateral, and right lateral diameter of the internal anal sphincter (IAS) and external anal sphincter (EAS) muscles. Maximum squeeze pressure was significantly correlated to muscle thickness of the EAS (P = 0.001). No association was found between resting pressure and IAS diameter. Women had significantly lower resting and squeeze pressures than men (P = 0.008 and P = 0.003, respectively), but age-related changes of function were only found for resting pressure. Endosonographic values of IAS and EAS did not differ between genders but were significantly correlated with age (P = 0.008 and P = 0.02, respectively). Because all correlations were rather weak, they only can explain a small portion of data variance. Anal manometry and anal ultrasound, therefore, are of complementary value and are both indicated in adequate clinical problems.

    Until now the evaluation of how to function on the sphincter muscle complex on the imaging study has been done by defecography. The purpose of this paper is to show the normal and abnormal functions of sphincter muscle complex at rest and squeeze using MRI. The subjects were 15 volunteers with informed consent and 13 post operative patients with a history anorectal anomalies. MR images were obtained with a 1.5 T unit. Sagittal and axial planes were evaluated both at rest and squeeze. Squeeze was simulated by insufflating a rectal balloon or enema on the volunteers. Only light stimulation was stressed on the post operative patients by means of balloon insufflation with 50 ml air. Under balloon stimulation, 71% of normal sphincter muscle complexes contracted only transverse dimention. The rest was as is. None revealed significant distension. All patients with continence demonstrated the same transverse contraction. Patients with incontinence showed no significant contraction. Under enema stimulation for normal subjects, sphincter muscle complex distended on both dimensions. Gluteal muscle contracted 50% of volunteers under enema stimulation. All post operative patients with continence demonstrated gluteal muscles contractions. Normal sphincter muscle complex contracts only in transverse dimension under balloon stimulation, which is caused by the muscle. Under enema stimulation, it distends on both dimensions. Gluteal muscle contract only under enema stimulation. In post operative patients, MRI shows different functions of anal sphincter muscle complex between continent and incontinent groups. It may explain causes of incontinence. The gluteal muscle and puborectal muscle seem to have one of the essentials for continence. (author)

    2015-06-01

    Sphincter of Oddi dyskinesia is a functional disorder of the papillary region which can lead to clinical symptoms due to functional obstruction of biliary and pancreatic outflow. Based on the severity of the clinical symptoms the disorder can be graded into three types (biliary and pancreatic types I-III). The manometric diagnosis of this disorder using sphincter of Oddi manometry is hampered by the relatively high risk of pancreatitis after endoscopic retrograde cholangiopancreatography. Although papillary manometry is often carried out in North America, in Europe this is the exception rather than the rule. Manometrically, sphincter of Oddi dyskinesia is characterized by an increased pressure in the biliary and/or the pancreatic sphincter segments and can be treated by endoscopic papillotomy. This overview counterbalances the arguments for primary invasive diagnostics and a pragmatic clinical approach, i.e. papillotomy should be directly carried out when a sphincter of Oddi dyskinesia is clinically suspected. For patients with biliary or pancreatic type I, endoscopic papillotomy is the treatment of choice. In biliary type II sphincter of Oddi manometry could be helpful for clinical decision-making; however, the exact risk-benefit ratio is still difficult to assess. In type III patient selection and the low predictive value of manometry for treatment success questions the clinical usefulness of sphincter of Oddi manometry.

    Up to this time the sigmoid colostomy has been widely accepted and conventional treatment for radiation-injured rectum, but patients without residual malignancy strongly desire to live without colostomy. We have tried to remove the involved rectal segments by sphincter-saving procedures. Four patients underwent these procedures, pull-through procedure in three and low anterior resection in one. Among sphincter-saving procedures, pull-through procedure was most adequate. Provided the following five conditions are fulfilled, pull-through procedure should be considered for severe radiation-injured rectum. (1) No recurrence of initial malignancy in the pelvis. (2) More than 2 cm intact rectal segment above dentate line may be preserved. (3) No radiation-injured segment in upper sigmoid. (4) No severe radiation damage in small intestine. (5) Patients under 70 year-old, with normal tonus of anal sphincter. (author)

    Stiff person syndrome is a neurologic disorder characterized by axial rigidity leading to progressive disability, with broad clinical spectrum. We report 2 cases with unique clinical presentation. Two young men suffered progressive urinary retention requiring bladder catheterization, anorectal spasms and constipation, complicated subsequently with lower extremity trigger-induced spasms, and gait instability. Associated symptoms revealed brainstem involvement (vertigo, diplopia, and cranial neuropathies) and dysautonomia (abnormal sweating and orthostatic hypotension). Anal manometry demonstrated incomplete relaxation of the anal sphincter. The first case was associated with diabetes mellitus type I, did not respond to classical therapies, but was responsive to rituximab. The second case responded to intravenous immunoglobulin infusions. Paraneoplastic profiles were negative, and anti-GAD65 antibody titers remained elevated despite successful therapeutic responses. We want to raise awareness that stiff person syndrome can present with esophageal, anorectal, and urethral sphincter disturbance. Rituximab is a good therapeutic option in intractable cases.

    2017-06-27

    Fecal incontinence (FI) is frequently associated with low sphincter pressures, sensory abnormalities, and advanced age. Twenty-three percent of patients with FI and 22% of healthy patients demonstrate dyssynergic defecation (DD) on high-resolution anorectal manometry. Overflow incontinence occurs in some DD patients with normal resting and squeeze anal sphincter pressures. Our aim was to identify factors associated with normal sphincter pressures in women with FI. We reviewed medical records of 134 women with FI. Patients with normal resting and squeeze anal pressures were compared with those with abnormal pressures using Wilcoxon rank sum test and Fisher exact. Multivariable logistic regression was performed to identify factors associated with normal resting and squeeze anal pressures. Among 134 women, abnormal resting and/or squeeze pressures were identified in 113 and normal pressures were identified in 21. Women with normal sphincter pressures were younger (mean age 52.7 ± 10.8 years vs 59.0 ± 14.0 years, P = 0.036), more often had abnormal defecation indices (100% vs 83.2%, P = 0.043) and higher rectal defecation pressures (30.8 ± 18.8 mm Hg vs 50.8 ± 22.6 mm Hg, P normal and abnormal sphincter pressure groups (P = 0.021). Dyssynergia subtypes I or III (odds ratio, 7.2; 95% confidence interval, 1.8-28.8) and age younger than 67 years (odds ratio, 8.5; 95% confidence interval, 1.5-48.6) were associated with greater odds of having normal sphincter pressures. Female FI patients with normal anal sphincter pressures are younger, have higher rectal defecation pressures, and more often have type I or type III DD.

    This study was performed to assess the differences in the birth canal lacerations following the lateral and fours posture deliveries compared with those following the supine posture deliveries. We examined the birth canal lacerations of our "low risk" pregnant women under the midwife-led delivery care at Japanese Red Cross Katsushika Maternity Hospital between April 2006 and March 2015. There were 3826, 1754 and 719 women who delivered with supine, lateral and fours postures. The rate of no laceration in the women who delivered with lateral posture was significant lower than that in the women who delivered with supine posture (OR 0.630, 95% CI 0.56-0.71, p < 0.01); however, the incidence of perineal laceration in the women who delivered with lateral posture was significant lower than that in the women who delivered with supine posture (OR 0.856, 95% CI 0.76-0.90, p < 0.01). The incidence of perineal laceration of third- or fourth-degree in the women who delivered with fours posture was significant higher than that in the women who delivered with supine posture (OR 2.28, 95% CI 1.2-4.2, p < 0.01). The current results may be to help for self-determination of birthing postures in prenatal women.

    To assess smooth muscle enfoldment and internal sphincter construction (SMESC) for improvement of continence after intersphincteric resection (ISR) for rectal cancer. Twenty-four Bama miniature pigs were randomly divided into a conventional ISR group and experimental SMESC group, with 12 pigs in each group. The proximal sigmoid colon was anastomosed directly to the anus in the ISR group. In the SMESC group, internal sphincter construction was performed. At 12 weeks before and after surgery, rectal resting pressure and anal canal length were assessed. Three-dimensional ultrasound was used to determine the thickness of the internal sphincter. After the animals were sacrificed, the rectum and anus were resected and pathological examinations were performed to evaluate the differences in sphincter thickness and muscle fibers. All 24 animals in the SMESC group and the ISR group survived the surgery. Twelve weeks post-surgery, the rectal resting pressure, length of the anal high-pressure zone and the postoperative internal sphincter thickness for the ISR group were significantly lower than for the SMESC group. There was a thickened area (about 2 cm) above the anastomotic stoma among animals from the SMESC group; in addition, the smooth muscles were significantly enlarged and enfolded when compared to the ISR group. This animal model study shows that the SMESC procedure achieved acceptable reconstruction of the internal anal neo-sphincter (IAN/S), without increasing surgical risk. However, the findings in this experimental animal model must be confirmed by clinical trials to determine the safety and efficacy of this procedure in clinical practice.

What is the clinical evidence base for tissue adhesives in the management of simple traumatic lacerations? Studies were identified by searches of the following databases: Cochrane Wounds Group Specialized Trials Register (September 2003), Cochrane Central Register of Controlled Trials (CENTRAL) (CDROM 2003, issue 3), MEDLINE (1966 to September 2003, week 1), EMBASE (1988 to 2003, week 36), Web of Science Science Citation Index (1975 to September 13, 2003) and various clinical trials registers (September 2003). Investigators and product manufacturers were contacted to identify additional eligible studies. The search terms included wounds and injuries, laceration, face injury, nose injury, tissue adhesives, and acrylates. Each study fulfilled the following criteria: (1) The study was a randomized controlled trial that compared tissue adhesives with standard wound closure (SWC) (sutures, staples, adhesive strips) or tissue adhesive with tissue adhesive. (2) The wounds were acute, linear lacerations less than 12 hours old, resulting from blunt or sharp trauma. (3) The wound length, width, and depth allowed for approximation of the edges with minimal tension after deep sutures were placed, if required. Studies were included with no language or publication status restriction, with participants of any age recruited in an emergency department, outpatient clinic, walk-in clinic, or other primary care setting. Studies were excluded if the wounds were stellate lacerations, puncture wounds, mammalian bites, infected, heavily contaminated or devitalized, crossing joints or mucocutaneous junctions, in hair-bearing areas, or in patients with keloid formation or chronic illness. The characteristics of the study and participants, interventions, outcome measures, and findings were extracted by one author and verified by a second

    Full Text Available Surgical sphincterotomy reduces anal tone and sphincter spasm and promotes ulcer healing. Because the surgery is associated with the side effect of faecal incontinence, pharmacological agents to treat chronic anal fissure have been explored recently. Glyceryl trinitrate (GTN ointment (0.2% has an efficacy of up to 68% in healing chronic anal fissure, but it is associated with headache as the major and most common side effect. Though botulinum toxin injected into the anal sphincter healed over 80% of chronic anal fis-sures, it is more invasive and expensive than GTN therapy. Diltiazem ointment achieved healing of chronic anal fissure comparable to 0.2% GTN ointment but was associated with fewer side effects. Other drugs that have been tried are lidocaine, the alpha-adrenergic antagonist indoramin, and the potassium channel opener minoxidil.

    To evaluate the usefulness of endoanal ultrasonography and to determine the imaging features of patients with fecal incontinence, anal abscess or anal fistula. Twenty five patients underwent endoanal ultrasonography between October 1995 and July 1996. Ten of these were fecal incontinence cases, eight had an anal abscess, and seven, an anal fistula. The incontinence grading scale (IGS) was used for clinical grading of fecal incontinence and pudendal nerve terminal motor latency (PNTML) for pudendal nerve injury. Endoanal ultrasonographic features and operative findings were retrospectively reviewed. Endoanal ultrasonography revealed defective sphincteric muscles in all three patients with myogenic fecal incontinence, but in six of seven cases with neurogenic fecal incontinence, these muscles were not difective. Myogenic and neurogenic incontience showed different findings (p=3D0.033). In comparison with surgical findings, endoanal ultrasonography was 88% accurate in anal abscess cases and 86% accurate in those of anal fistula. Endoanal ultrasonography in conjunction with PNTML was very useful for the detection of the site and severity of sphincteric muscle defect and diagnosis of the etiology of fecal incontinence. Through analysis of the site and type of lesion, the procedure can also serve as a guide to the surgical treatment of patients with anal abscess or fistula.=20.

    Full Text Available Abstract Objective To compare the function of the pelvic floor in primiparae before and during pregnancy with the status post partum concerning symptoms of incontinence, sphincter ruptures, bladder-neck mobility and the influence of the different modes of deliveries. Methods Questionnaire evaluating symptoms of urinary and anal incontinence in nulliparous women before and after delivery and correlating these symptoms with functional changes of the pelvic floor based on a careful gynaecologic examination as well as perineal and endoanal ultrasound. Results 112 women were included in our study and came for the first visit, 99 women returned for follow-up 6 months after childbirth. Stress and flatus incontinence significantly increased from before pregnancy (3 and 12% to after childbirth (21 and 28% in women with spontaneous delivery or vacuum extraction. No new symptoms occurred after c-section. There was no significant difference between the bladder neck position before and after delivery. The mobility of the bladder neck was significantly higher after vaginal delivery using a vacuum extraction compared to spontaneous delivery or c-section. The bladder neck in women with post partum urinary stress incontinence was significantly more mobile than in continent controls. The endoanal ultrasound detected seven occult sphincter defects without any correlation to symptoms of anal incontinence. Conclusion Several statistically significant changes of the pelvic floor after delivery were demonstrated. Spontaneous vaginal delivery or vacuum extraction increases the risk for stress or anal incontinence, delivery with vacuum extraction leads to higher bladder neck mobility and stress incontinent women have more mobile bladder necks than continent women.

    Anal metastasis from colorectal cancer rarely occurs, but it severely impairs the patient's quality of life, often requiring wide resection including the anal sphincter with permanent colostomy. This lesion can be misdiagnosed as a perianal fistula or an abscess, and it can be overlooked at the time of surgery because it is not included in the routine surgical extent of low anterior resection. We report two rare cases of anal metastasis from colorectal cancer. In both cases, perianal nodules with an internal solid portion were detected on preoperative rectal magnetic resonance imaging and additional local excisions of the anal lesions were performed during the process of treatment. Anal metastasis was pathologically confirmed by histology and immunohistochemical staining.

    Renal or ureteral diseases are often associated with gastrointestinal symptoms. In this communication, we studied the effect of renal pelvic or ureteric distension on the anorectal function in 12 healthy volunteers. A 3F balloon-tipped catheter was introduced into the renal pelvis. The balloon was filled with saline in increments of 2 ml up to 12 ml and the pressure response of the rectum and anal canal was recorded. Balloon filling was performed twice: rapidly (1 ml/sec) and slowly (1 ml/min). The test was repeated in the ureter with balloon fillings in increments of 0.25 ml up to 1 ml. The electromyographic (EMG) response of the external anal sphincter to distension of the renal pelvis or ureter was evaluated. The pressure response of the rectum, anal canal and external anal sphincter to distension of the anesthetised renal pelvis or ureter was then determined. The test was repeated after external anal sphincter anaesthetisation. Rapid renal pelvic or ureteric distension increased the anal canal pressure (p 0.05). With 10 and 12 ml rapid renal pelvis distension and with 0.75 and 1 ml rapid ureteric distension, the EMG activity of the external anal sphincter increased and was accompanied with loin and anal pain. Slow renal pelvic or ureteric distension caused no significant change in the anal or rectal pressures (p > 0.05) or in the EMG activity of the external anal sphincter and no anal pain was perceived. Distension of the anesthetised renal pelvis or ureter effected no changes in anal or rectal pressures (p > 0.05). The anesthetised external anal sphincter as well as the anal or rectal pressure did not respond to renal pelvis or ureteric distension. In conclusion, rapid renal pelvic or ureteric distension stimulates the mechanoreceptors in the renal pelvis or ureteric wall leading to reflex external anal sphincter contraction. This leads to elevation of the anal canal pressure. The findings suggest the possible involvement of a "reno-anal reflex" which is

    Skin cuts and lacerations are frequent injuries. A perfect result of the treatment is going without saying for the patient and its relatives. But there are some aspects to note for an adequate wound management. The main aims of wound management are clear: assist in hemostasis, to avoid infection and pain, and to ensure an esthetically pleasing scar. For these we have to treat not only the wound. Taking care for the hole patient and treating the sore pain and preventing painfull manipulations is the goal for the patients satisfaction. The basic aspects of wound healing and wound management will be described. Sutures, tissue adhesives, staples, and skin-closure tapes are options in the outpatient setting. Although suturing is the preferred method for laceration repair, tissue adhesives are similar in patient satisfaction, infection rates, and scarring risk in low skin-tension areas and may be also more cost-effective. Patient education and appropriate procedural coding are important after the repair. Please do not forget in every case to ask for the tetanus immunization and to think about an antibiotic therapy in case of human or animal bites and for wounds in risk areas and with contamination.

    Many new devices and techniques are being developed to attempt a reduction in embolic stroke risk for patients with atrial fibrillation who are either unable or unwilling to maintain long-term anticoagulation. One of these new devices (LARIAT®, SentreHEART Inc., Redwood City, California, USA) employs delivery of an epicardial suture to ligate the left atrial appendage after percutaneous pericardial and transseptal access. This series presents three clinical cases that demonstrate a serious and recurrent complication of left atrial laceration and cardiac tamponade shortly following delivery of an epicardial suture ligation to the left atrial appendage. Three clinical cases are described in detail with pre- and postprocedure angiography and echocardiography as well as illustrations reflecting the surgeon's findings on direct visualization of the left atrial lacerations postligation. Potential hypotheses of each injury are examined in light of the case timelines and findings at sternotomy. There was no suggestion that tamponade was related to pericardial or transseptal access, but rather a complication with device delivery. These three patients quickly progressed to clinical cardiac tamponade despite attempted drainage, stressing the importance of cardiovascular surgery backup, including a cardiopulmonary bypass pump, when delivering novel, percutaneous ligation devices for the left atrial appendage.

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    Full Text Available Context: Little seems to be known about the sexual dysfunction (SD in lumbar intervertebral disc herniation. Aims: Investigation of sexual and sphincter dysfunction in patient with lumbar disc hernitions. Settings and Design: A retrospective analysis. Materials and Methods: Sexual and sphincter dysfunction in patients admitted with lumbar disc herniations between September 2012-March 2014. Statistical Analysis Used: Statistical analysis was performed using the Predictive Analytics SoftWare (PASW Statistics 18.0 for Windows (Statistical Package for the Social Sciences, SPSS Inc., Chicago, Illinois. The statistical significance was set at P < 0.05. The Wilcoxon signed ranks test was used to evaluate the difference between patients. Results: Four patients with sexual and sphincter dysfunction were found, including two women and two men, aged between 20 and 52 years. All of them admitted without low back pain. In addition, on neurological examination, reflex and motor deficit were not found. However, almost all patients had perianal sensory deficit and sexual and sphincter dysfunction. Magnetic resonance imaging (MRI of three patients displayed a large extruded disc fragment at L5-S1 level on the left side. In fourth patient, there were not prominent disc herniations. There was not statistically significant difference between pre-operative and post-operative sexual function, anal-urethral sphincter function, and perianal sensation score. A syndrome in L5-S1 disc herniation with sexual and sphincter dysfunction without pain and muscle weakness was noted. We think that it is crucial for neurosurgeons to early realise that paralysis of the sphincter and sexual dysfunction are possible in patients with lumbar L5-S1 disc disease. Conclusion: A syndrome with perianal sensory deficit, paralysis of the sphincter, and sexual dysfunction may occur in patients with lumbar L5-S1 disc disease. The improvement of perianal sensory deficit after surgery was

    Purpose: This study was designed to evaluate the clinical success, complications, and transfusion requirements based on the location of and agents used for splenic artery embolization in patients with splenic trauma. Methods: A retrospective study was performed of patients with splenic trauma who underwent angiography and embolization from September 2000 to January 2010 at a level I trauma center. Electronic medical records were reviewed for demographics, imaging data, technical aspects of the procedure, and clinical outcomes. Results: Fifty patients were identified (34 men and 16 women), with an average age of 48 (range, 16-80) years. Extravasation was seen on initial angiography in 27 (54%) and was absent in 23 (46%). All 27 patients with extravasation were embolized, and 18 of 23 (78.2%) without extravasation were embolized empirically. Primary clinical success was similar (>75%) across all embolization locations, embolic agents, and grades of laceration treated. Of 45 patients treated, 9 patients (20%) were embolized in the main splenic artery, 34 (75.6%) in the splenic hilum, and 2 (4.4%) were embolized in both locations. Partial splenic infarctions developed in 47.3% treated in the splenic hilum compared with 12.5% treated in the main splenic artery. There were four (8.9%) mortalities: two occurred in patients with multiple critical injuries and two from nonbleeding etiologies. Conclusions: Embolization of traumatic splenic artery injuries is safe and effective, regardless of the location of treatment. Embolization in splenic hilar branches may have a higher incidence of infarction. The grade of laceration and agents used for embolotherapy did not impact the outcomes.

    Advances in surgical techniques and paradigm changes in rectal cancer treatment have led to a drastic decline in the abdominoperineal resection rate, and sphincter-preserving operation is possible in distal rectal cancer. The aim of this study is to evaluate the long-term incidence of permanent stoma after sphincter-preserving surgery for low rectal cancer and its corresponding risk factors. From 2000 to 2014, patients who underwent sphincter-preserving low anterior resection for low rectal cancer (within 5 cm from the anal verge) were included. The occurrence of permanent stoma over time and its risk factors were investigated by using a Cox proportional hazards regression model. This study included 194 patients who underwent ultra-low anterior resection for distal rectal cancer, and the median follow-up period was 77 months for the surviving patients. Forty-six (23.7%) patients required a permanent stoma eventfully. Anastomotic-related complications and disease progression were the main reasons for permanent stoma.

  14. Cough-Anal Reflex May Be the Expression of a Pre-Programmed Postural Action

    Directory of Open Access Journals (Sweden)

    Paolo Cavallari

    2017-09-01

    Full Text Available When coughing, an involuntary contraction of the external anal sphincter occurs, in order to prevent unwanted leakages or sagging of the pelvis muscular wall. Literature originally described such cough-anal response as a reflex elicited by cough, therefore identifying a precise cause-effect relationship. However, recent studies report that the anal contraction actually precedes the rise in abdominal pressure during cough expiratory effort, so that the sphincter activity should be pre-programmed. In recent years, an important family of pre-programmed muscle activities has been well documented to precede voluntary movements: these anticipatory actions play a fundamental role in whole body and segmental postural control, hence they are referred to as anticipatory postural adjustments (APAs. On these basis, we searched in literature for similarities between APAs and the cough-anal response, observing that both follow the same predictive homeostatic principle, namely that anticipatory collateral actions are needed to prevent the unwanted mechanical consequences induced by the primary movement. We thus propose that the cough-anal response also belongs to the family of pre-programmed actions, as it may be interpreted as an APA acting on the abdominal-thoracic compartment; in other words, the cough-anal response may actually be an Anticipatory Sphincter Adjustment, the visceral counterpart of APAs.

    Full Text Available Abstract Background This report describes a new technique of sphincter saving anorectoplasty (SSARP for the repair of anorectal malformations (ARM. Methods Twenty six males with high ARM were treated with SSARP. Preoperative localization of the center of the muscle complex is facilitated using real time sonography and computed tomography. A soft guide wire is inserted under image control which serves as the route for final pull through of bowel. The operative technique consists of a subcoccygeal approach to dissect the blind rectal pouch. The separation of the rectum from the fistulous communication followed by pull through of the bowel is performed through the same incision. The skin or the levators in the midline posteriorly are not divided. Postoperative anorectal function as assessed by clinical Wingspread scoring was judged as excellent, good, fair and poor. Older patients were examined for sensations of touch, pain, heat and cold in the circumanal skin and the perineum. Electromyography (EMG was done to assess preoperative and postoperative integrity of external anal sphincter (EAS. Results The patients were separated in 2 groups. The first group, Group I (n = 10, were newborns in whom SSARP was performed as a primary procedure. The second group, Group II (n = 16, were children who underwent an initial colostomy followed by delayed SSARP. There were no operative complications. The follow up ranged from 4 months to 18 months. Group I patients have symmetric anal contraction to stimulation and strong squeeze on digital rectal examination with an average number of bowel movements per day was 3–5. In group II the rate of excellent and good scores was 81% (13/16. All patients have an appropriate size anus and regular bowel actions. There has been no rectal prolapse, or anal stricture. EAS activity and perineal proprioception were preserved postoperatively. Follow up computed tomogram showed central placement the pull through bowel in between

He gave a history of playing with a river crab when suddenly the crab clamped his fingers. He attempted to fling the crab off, but the crab flew and hit his right eye. Ocular examination revealed a right eye corneal ulcer with clumps of fibrin located beneath the corneal ulcer and 1.6 mm level of hypopyon. At presentation, the Seidel test was negative, with a deep anterior chamber. Culture from the corneal scrapping specimen grew Citrobacter diversus and Proteus vulgaris, and the boy was treated with topical gentamicin and ceftazidime eyedrops. Fibrin clumps beneath the corneal ulcer subsequently dislodged, and revealed a full-thickness corneal laceration wound with a positive Seidel test and shallow anterior chamber. The patient underwent emergency corneal toileting and suturing. Postoperatively, he was treated with oral ciprofloxacin 250 mg 12-hourly for 1 week, topical gentamicin, ceftazidime, and dexamethasone eyedrops for 4 weeks. Right eye vision improved to 6/9 and 6/6 with pinhole at the 2-week follow-up following corneal suture removal. Keywords: corneal ulcer, pediatric trauma, ocular injury

    Full Text Available Objective. To determine if there is an association between BMI and 3rd- or 4th-degree perineal lacerations in normal spontaneous and operative vaginal deliveries. Study Design. We performed a retrospective case control study using a large obstetric quality improvement database over a six-year period. Cases were identified as singleton gestations with third- and fourth-degree lacerations. Controls were obtained randomly from the database of patients without third- or fourth-degree lacerations in a 1 : 1 ratio. Univariate and multivariate logistic regression analyses were performed. Results. Of 32,607 deliveries, 22,011 (67.5% charts with BMI documented were identified. Third- or fourth-degree lacerations occurred in 2.74% (n=605 of patients. 37% (n=223 were identified in operative vaginal deliveries. In the univariate analysis, obesity, older maternal age, non-Asian race, and birth weight <4000 g were all protective against 3rd- and 4th-degree lacerations. After controlling for age, race, mode of vaginal delivery, and birth weight, obesity remained significant. Conclusion. Being obese may protect against third- and fourth-degree lacerations independent of parity, race, birth weight, and mode of delivery.

    The aetiopathogenesis of chronic anal fissure (CAF) is unclear and is probably multifactorial. CAF represents 10-15% of proctological consultations. This case report identifies adulthood sexual abuse as a significant risk and a potential aetiopathogenic factor of CAF This case history was discovered while carrying out administrated interviews during authors' clinical retrospective study on CAF. The clinical presentation of this 49-year-old woman is predominated by chronic anal lesions (anal tears in the anoderm, anal sphincter hypertrophy), associated medical history as a high consumer of healthcare with very poor mental health, chronic traumatic anal sex practice history, and especially persistent recurrences of gastro-intestinal symptoms after surgery. Surgical history is summarized as: 7x spontaneous abortion; 5x fistulectomy and 3x anal abscess; 4x Bartholin's gland; 4x hypertrophy papilla ablation; 2x anal manometry, 2x fissurectomy and 1x sphincterotomy; 2x haemorrhoid; and 1x hysterectomy. These symptoms initially started and the operations in particular took place after she was married. After 26 years of sexual abuse within her marriage, the clinical diagnosis was made and was consented by this patient. A referral to a psychiatrist was evident and a long course of multidisciplinary therapy (medical, surgical, physiological and psychological approaches) seemed to be of benefit, in terms of improving the clinical symptoms. Authors suggest that physicians should suspect sexual abuse in any patient with a medical history as a high consumer of healthcare and especially when there is persistent recurrence after the lateral subcutaneous internal sphincterotomy. We recognise that the link or causality is difficult to prove and further study is probably needed to shed light on the link between sexual abuse and CAF: although in the United Kingdom, over 20.83% of the population are subject to sexual abuse. 83%.

    The purpose of this study was to assess the efficacy of percutaneous nerve evaluation (PNE) in women with faecal incontinence (FI) following obstetric anal sphincter injury and to relate the outcomes to baseline factors, with special emphasis on the extent of the sphincter defect. This was a prospective study at a tertiary colorectal referral unit at the University Hospital of North Norway conducted from 2012 to 2014. Sixty-three women underwent a 3-week PNE using a tined lead and the Verify ® external neurostimulator. The primary outcome was efficacy, defined as the percentage reduction in weekly FI episodes, and patients with a reduction of 50% or more were defined as responders. Baseline factors affecting the primary outcome were explored. Sphincter defects were classified with a validated three-dimensional endoanal ultrasound defect score. Fifty-six (89%) of the 63 women were responders with a reduction in weekly FI episodes of 94.5%, from a median (interquartile range) of 4.8 (2.0-11.0) to 0.5 (0-2.0) (P < 0.001). Twenty-nine (52%) reported no weekly FI episodes, and urgency episodes disappeared in 18 (32%). In the multivariable linear regression model, efficacy was related to concomitant urinary incontinence (P = 0.04), body mass index (BMI) (P = 0.03) and pain during PNE (P = 0.046) but not to the extent of the sphincter defect (P = 0.1). Responders had a higher St Mark's score than nonresponders (P = 0.046). The vast majority of women had successful PNE tests. Responders had higher baseline St Mark's scores than nonresponders. Efficacy was related to concomitant urinary incontinence, BMI and pain, not to the extent of the sphincter defect.

    1995-01-01

    Purpose: To determine if preoperative radiation therapy allows sphincter preservation in the treatment of rectal cancer. Methods and Materials: Thirty patients with the diagnosis of invasive, resectable, primary adenocarcinoma of the rectum limited to the pelvis were enrolled on a Phase I/II trial of preoperative radiation therapy plus low anterior resection/coloanal anastomosis. By preoperative assessment, all patients had invasive tumors (2: T2, 28: T3) involving the distal half of the rectum and required an abdominoperineal resection. The median tumor size was 4 cm (range: 1.5-6 cm) and the median distance from the anal verge was 4 cm (range: 3-7 cm). The whole pelvis received 46.8 Gy followed by a 3.60 Gy boost to the primary tumor bed. The median follow-up was 43 months (range: 6-82 months). Results: Of the 29 patients who underwent resection, 3 (10%) had a complete pathologic response and 24 (83%) were able to successfully undergo a low anterior resection/coloanal anastomosis. The incidence of local failure was crude: 17% and 4-year actuarial: 23%. The 4-year actuarial survival was 75%. One patient developed a partial disruption of the anastomosis and two developed rectal stenosis. Analysis of sphincter function using a previously published scale was performed at the time of last follow-up in 22 of the 24 patients who underwent a low anterior resection/coloanal anastomosis. Function was good or excellent in 77%. The median number of bowel movements/day was two (range: 1-6). Conclusions: This technique may be an alternative to an abdominoperineal resection in selected patients. Continued follow-up is needed to determine if this approach ultimately has similar local control and survival rates as an abdominoperineal resection

    Full Text Available The study was conducted on ten mares suffering from third degree rectovestibular laceration. Four uterine washes were performed in all cases by using diluted betadine (mixing 5ml of betadine antiseptic solution in 1 liter of sterile saline to control vaginal and uterine infections before surgery. Surgical repair of third degree rectovestibular laceration was done by one-stage Goetz technique after four to six weeks of initial injury, with the lateral dissection continued extensively until the two flaps were created and brought to the midline without any tension. Primary healing occurred in all cases without significant complications. The obtained results indicate that mares with third degree rectovestibular lacerations are candidates for uterine wash and one-stage Goetz technique with excessive lateral continuation of the flap.

    Knowledge of the innervation of pelvic floor and sphincter muscles is of great importance to understanding the pathophysiology of female pelvic floor dysfunctions. This report presents our high-density intravaginal and intrarectal electromyography (EMG) probes and a comprehensive innervation zone (IZ) imaging technique based on high-density EMG readings to characterize the IZ distribution. Both intravaginal and intrarectal probes are covered with a high-density surface electromyography electrode grid (8 × 8). Surface EMG signals were acquired in ten healthy women performing maximum voluntary contractions of their pelvic floor. EMG decomposition was performed to separate motor-unit action potentials (MUAPs) and then localize their IZs. High-density surface EMG signals were successfully acquired over the vaginal and rectal surfaces. The propagation patterns of muscle activity were clearly visualized for multiple muscle groups of the pelvic floor and anal sphincter. During each contraction, up to 218 and 456 repetitions of motor units were detected by the vaginal and rectal probes, respectively. MUAPs were separated with their IZs identified at various orientations and depths. The proposed probes are capable of providing a comprehensive mapping of IZs of the pelvic floor and sphincter muscles. They can be employed as diagnostic and preventative tools in clinical practices.

    To assess the feasibility and adequacy of double stapling technique (DST) and anal sphincter preservation with laparoscopic approach for low rectal cancer. DST and low/ultralow/coloanal anastomoses were performed laparoscopically on 30 patients with low rectal cancer. The 30 laparoscopic DST and low/ultralow/colo-anal anastomoses with anal sphincter preservation were successfully completed, and not one of the cases was converted to open procedures. The operation time was 155 min with the ranges from 110 to 320 min. The operative blood loss was 20 ml with a range between 5 and 80 ml. The time of bowel function restoration and post-operative ambulation was 1-2 days after the operation. 14 patients had postoperative analgesic requirement. The hospital stay varied from 5 to 14 days, averaging 8 days, and there were no intraoperative and postoperative complications in the 30 patients. Laparoscopic DST and low/ultralow/colo-anal anastomoses for low rectal cancer is a perspective minimally invasive technique, which is feasible, safe and effective. With the use of this technique, surgeons could accomplish higher rates of sphincter preservation, more accurate autonomic nerve preservation and good micturation with decreased postoperative pain and rapid recovery.

    Anal metastasis of colorectal cancer is very rare and is usually associated with a history of anal disease, including anal fistula, fissure, hemorrhoidectomy, and anastomotic injury. We report a case of rectal cancer with a synchronous anal metastasis consisting of adenocarcinoma of squamous cells without a history of anal disease. A 60-year-old woman had a chief complaint of melena. She had a 1.5-cm anal tumor on the perianal skin, and a Bollman type 2 rectal tumor on the Ra portion was found on colonoscopy. Biopsy of both tumors revealed a similar histology of well- to moderately differentiated adenocarcinoma. There was no sign of metastases in lymph nodes or other organs. For the purpose of diagnosis and treatment, transperineal local resection of the anal tumor was performed, and it was histologically identified as adenocarcinoma of squamous cells with no invasion to muscles, lymph ducts, or microvessels. The pathological margin was free. Then, to achieve radical cure, laparoscopic low anterior resection (LAR) with D3 lymphadenectomy was performed. The histological diagnosis of the anal tumor was adenocarcinoma of squamous cells without invasion to muscles, lymph ducts, or vessels. The surgical margin was completely free. Immunohistochemical analysis of both tumors revealed similar staining patterns, and the final diagnosis was rectal cancer with metastasis to the anal skin. The patient received no postoperative therapy, and no recurrences have been observed 12 months after surgery. We expect that our sphincter-preserving surgical strategy provided a good prognosis for the synchronous rectal cancer and anal metastasis. This is a rare report of a case with an anal metastasis of colorectal cancer on perianal squamous cells without a history of anal disease that was resected while preserving anal function.

    Full Text Available Objective: endoanal ultrasonography can detect organic causes of anal pain without pathology on physical examination. The aim of this study is to evaluate the importance of endoanal ultrasonography in the diagnosis and therapeutic management of idiopathic and functional anal pain. Material and methods: retrospective study, between 15 March 2005 and 15 June 2008, of all patients with proctalgia and normal examination or with alterations not responsible for anal pain at proctologic exam that have undergone an endoanal ultrasonography. Results: a total of 90 patients were analyzed, with a mean age of 50.5 years, 58% were female. Twenty-three patients had functional anal pain clinic criteria. Endoanal ultrasonography revealed alterations in 49% of patients. The primary findings were changes in sphincters in 14 patients, followed by anal sepsis in 12 patients, anal fissure in 10 patients, perirectal lesions in 6 patients and ulcer of the anal canal in 2 patients. Of the patients with sphincter defects, 5 patients had criteria of chronic anal pain. In this group of patients, no differences were found in manometric and defecographic results between the different ultrasound abnormalities. Conclusions: the endoanal ultrasonography detected occult organic lesions to proctologic examination, in half the patients with anal pain. Ultrasound abnormalities were found in 22% of patients with functional anal pain. However, there was no correlation between ultrasound findings and physiological studies, and therefore could not find etiological or pathogenic factors of functional anal pain.Objetivo: la ecografía endoanal puede detectar causas orgánicas en el dolor anal sin patología en la exploración física. El objetivo de este estudio es evaluar la importancia de la ecografía endoanal en el diagnóstico y en el abordaje terapéutico del dolor anal idiopática y funcional.

    We performed colonic J-pouch anal anastomosis in 61 patients with rectal cancer located <4 cm from the anal verge. Surgical and oncological results were evaluated in multimodality therapy for advanced rectal cancer. According to Wexner's score, 7% of patients were fully continent, 71% had acceptable function with minor continence problems, and 22% were incontinent. No patients required intermittent self-catheterization during follow-up. After a median follow-up of 49 months, there was only 1 case of local recurrence after surgery. Our surgical approach irrespective of internal sphincter resection produces satisfactory functional and oncological results in multimodality therapy using preoperative chemoradiotherapy for lower rectal cancer.

    2010-01-01

    Objective: To determine and evaluate the method of localization of anal verge by multislice spiral CT. To provide an imaging reference for operative guidance of low-rectal cancer. Methods Forty eight consecutive adult patients suspected of abnormalities other than rectal disease were evaluated with abdominal and pelvic CT scans since August, 2009. They were divided into two groups based on sex and age. There were 23 men and 25 women. The ages of young group were 28 to 50 years and the average age was 41 years. The ages of elderly group were 52 to 81 years and the average age was 64 years. A small cotton ball dipped with contrast media was put at the anal verge as a marker and CT scans were performed with 64-slice spiral CT scanner. The distances between the cotton balls and the lower margin of the pubis combination (La), the lower margin of the Sth sacral vertebra (Lb), the inferior aperture of minor pelvis (Lc) and the lower margin of the basement of external anal sphincter (Ld) were measured on the mid- sagittal images obtained by MPR. The averages, the standard deviations (s), the 95% and 80% confidence intervals of La, Lb, Lc and Ld were calculated. We took the intervals of ±1.96 s or ±1.28 s 0.05) between two different sex groups [male group, (10.0±1.2) mm], female group, (9.6±1.2) mm and between two age groups [young group, (9.6±1.2) mm, elderly group, (9.9±1.3) mm]. Conclusions: The lower margin of the basement of external anal sphincter was a useful anatomic landmark for localizing the anal verge, and could be definitely identified on the middle sagittal pelvic CT image. The distance between the structure and anal verge is constant enough and can be used in measuring distance from low rectal lesion to the anal verge. (authors)

    This study was conducted to provide normal reference features for canine and feline anal sacs using ultrasound, low-field magnetic resonance imaging (MRI) and radiograph contrast as diagnostic imaging tools. A total of ten clinically normal beagle dogs and eight clinically normally cats were included. General radiography with contrast, ultrasonography and low-field MRI scans were performed. The visualization of anal sacs, which are located at distinct sites in dogs and cats, is possible with a contrast study on radiography. Most surfaces of the anal sacs tissue, occasionally appearing as a hyperechoic thin line, were surrounded by the hypoechoic external sphincter muscle on ultrasonography. The normal anal sac contents of dogs and cats had variable echogenicity. Signals of anal sac contents on low-field MRI varied in cats and dogs, and contrast medium using T1-weighted images enhanced the anal sac walls more obviously than that on ultrasonography. In conclusion, this study provides the normal features of anal sacs from dogs and cats on diagnostic imaging. Further studies including anal sac evaluation are expected to investigate disease conditions.

    PurposeWe evaluated the management of transcatheter arterial embolization for postpartum hemorrhage caused by vaginal laceration.Materials and MethodsWe reviewed seven cases of patients (mean age 30.9 years; range 27–35) with intractable hemorrhages and pelvic hematomas caused by vaginal lacerations, who underwent superselective transcatheter arterial embolization from January 2008 to July 2014. Postpartum hemorrhage was evaluated by angiographic vascular mapping to determine the vaginal artery’s architecture, technical and clinical success rates, and complications.ResultsThe vaginal artery was confirmed as the source of bleeding in all cases. The artery was found to originate from the uterine artery in three cases, the uterine and obturator arteries in two, or the internal pudendal artery in two. After vaginal artery embolization, persistent contrast extravasation from the inferior mesenteric artery as an anastomotic branch was noted in one patient. Nontarget vessels (the inferior vesical artery and nonbleeding vaginal arterial branches) were embolized in one patient. Effective control of hemostasis and no post-procedural complications were confirmed for all cases.ConclusionPostpartum hemorrhages caused by vaginal lacerations involve the vaginal artery arising from the anterior trunk of the internal iliac artery with various branching patterns. Superselective vaginal artery embolization is clinically acceptable for the successful treatment of vaginal laceration hemorrhages, with no complications. After vaginal artery embolization, it is suggested to check for the presence of other possible bleeding vessels by pelvic aortography with a catheter tip at the L3 vertebral level, and to perform a follow-up assessment.

    Penetrating injury to the forearm may cause an isolated radial or ulnar artery injury, or a complex injury involving other structures including veins, tendons and nerves. The management of forearm laceration with arterial injury involves both operative and nonoperative strategies. An evolution in management has emerged especially at urban trauma centers, where the multidisciplinary resource of trauma and hand subspecialties may invoke controversy pertaining to the optimal management of such injuries. The objective of this review was to provide an evidence-based, systematic, operative and nonoperative approach to the management of isolated and complex forearm lacerations. A comprehensive search of MedLine, Cochrane Library, Embase and the National Guideline Clearinghouse did not yield evidence-based management guidelines for forearm arterial laceration injury. No professional or societal consensus guidelines or best practice guidelines exist to our knowledge. The optimal methods for achieving hemostasis are by a combination approach utilizing direct digital pressure, temporary tourniquet pressure, compressive dressings followed by wound closure. While surgical hemostasis may provide an expedited route for control of hemorrhage, this aggressive approach is often not needed (with a few exceptions) to achieve hemostasis for most forearm lacerations. Conservative methods mentioned above will attain the same result. Further, routine emergent or urgent operative exploration of forearm laceration injuries are not warranted and not cost-beneficial. It has been widely accepted with ample evidence in the literature that neither injury to forearm artery, nerve or tendon requires immediate surgical repair. Attention should be directed instead to control of bleeding, and perform a complete physical examination of the hand to document the presence or absence of other associated injuries. Critical ischemia will require expeditious surgical restoration of arterial perfusion. In a

    To determine the effect of perineal lacerations on pelvic floor outcomes, including urinary and anal incontinence, sexual function, and perineal pain in a nulliparous cohort with low incidence of episiotomy. Nulliparous women were prospectively recruited from a midwifery practice. Pelvic floor symptoms were assessed with validated questionnaires, physical examination, and objective measures in pregnancy and 6 months postpartum. Two trauma groups were compared, those with an intact perineum or only 1st degree lacerations and those with second-, third-, or fourth-degree lacerations. Four hundred and forty-eight women had vaginal deliveries. One hundred and fifty-one sustained second-degree or deeper perineal trauma and 297 had an intact perineum or minor trauma. Three hundred and thirty-six (74.8%) presented for 6-month follow-up. Perineal trauma was not associated with urinary or fecal incontinence, decreased sexual activity, perineal pain, or pelvic organ prolapse. Women with trauma had similar rates of sexual activity; however, they had slightly lower sexual function scores (27.3 vs 29.1). Objective measures of pelvic floor strength, rectal tone, urinary incontinence, and perineal anatomy were equivalent. The subgroup of women with deeper (> 2 centimeter) perineal trauma demonstrated increased likelihood of perineal pain (15.5% vs 6.2%) and weaker pelvic floor muscle strength (61.0% vs 44.3%) compared with women with more superficial trauma. Women having second-degree lacerations are not at increased risk for pelvic floor dysfunction other than increased pain, and slightly lower sexual function scores at 6 months postpartum. © 2016 Wiley Periodicals, Inc.

    Sphincter-preserving procedures for the treatment of transsphincteric fistulas fail in at least one out of every three patients. It has been suggested that failure is due to ongoing disease in the remaining fistula tract. Cytokines play an important role in inflammation. At present, biologicals targeting cytokines are available. Therefore, detection and identification of cytokines in anal fistulas might have implications for future treatment modalities. The objective of the present study was to assess local production of a selected panel of cytokines in anal fistulas, including pro-inflammatory interleukin (IL)-1β and tumor necrosis factor α (TNF-α). Fistula tract tissue was obtained from 27 patients with a transsphincteric fistula of cryptoglandular origin who underwent flap repair, ligation of the intersphincteric fistula tract or a combination of both procedures. Patients with a rectovaginal fistula or a fistula due to Crohn's disease were excluded. Frozen tissue samples were sectioned and stained using advanced immuno-enzyme staining methods for detection of selected cytokines, IL-1β, IL-8, IL-10, IL-12p40, IL-17A, IL-18, IL-36 and TNF-α. The presence and frequencies of cytokine-producing cells in samples were quantitated. The key finding was abundant expression of IL-1β in 93 % of the anal fistulas. Frequencies of IL-1β-producing cells were highest (>50 positive stained cells) in 7 % of the anal fistulas. Also, cytokines IL-8, IL-12p40 and TNF-α were present in respectively 70, 33 and 30 % of the anal fistulas. IL-1β is expressed in the large majority of cryptoglandular anal fistulas, as well as several other pro-inflammatory cytokines.

    To describe the MR imaging findings in adults presenting with anal incontinence following pull-through perineoplasty for anorectal atresia. 15 adults (12 male, 3 female; age 22-52 years) with anal incontinence following a prior perineal pull-through procedure as an infant for anorectal atresia were identified retrospectively. MR imaging was performed using either an endoanal coil or body coil. MR images were reviewed by three observers who noted whether pelvic floor and sphincter muscles were present and, if so, whether they were thinned or not. Data were tabulated and raw frequencies determined. Images were unavailable for one patient, leaving 14 for analysis. Anal stenosis prevented endoanal coil placement in 5. The pull-through was anatomically correct in 12 (86 %) patients but was misdirected in 2. Thinned muscle was seen in 11 (79 %) patients. External sphincter thinning was commonest (present in 10 patients), with levator plate thinning least common (present in 4 patients). Only one patient had thinning of all muscle groups. MR imaging may be used to determine the extent and quality of residual pelvic floor and anal sphincter muscle in adults who have functional disability following pull-through perineoplasty for anorectal agenesis.

    Full Text Available Abstract This issue of CytoJournal contains an article on screening for anal intraepithelial neoplasia in high-risk male patients. This accompanying Editorial focuses on current understanding of this relatively new disease entity, with insights as to the potential role of screening cytopathology in the epidemiology, pathophysiology and clinical management of this HIV and HPV related anal lesion, which predominates in male patients living long-term with AIDS. Mention is made of techniques of obtaining samples, methods of preparation, and morphologic classification. Issues of anoscopic confirmation, as well as topical and surgical management are emphasized. The similarity of initial experiences in anal screening to problems encountered early in cervical cancer screening programs several decades ago, are highlighted.

    1997-01-01

    PURPOSE: To determine the long term follow-up of sphincter preservation with pre-operative RT and coloanal anastomosis for rectal cancer. MATERIALS AND METHODS: A total of 36 pts (M:25, F:11) with invasive, clinically resectable, primary adenocarcinoma of the rectum were enrolled from 1/87 through 4/96 on a prospective Phase I/II trial. All patients were examined in the office by their operating surgeon prior to the start of RT and were judged clinically to require an abdominoperineal resection (APR) due to the proximity (but not invasion of) the tumor to the anal sphincter. By transrectal ultrasound, clinical T stage was T2:5, and T3:31. The median age was 55 years (range: 33-76 years), and the median distance from the anal verge was 4 cm (range: 3-7 cm). The median tumor size was 3.8 cm (range: 1.5-7 cm). Pts received 4680 cGy (180 cGy/day) to the whole pelvis followed by a boost to 5040 cGy followed by surgery 4-5 weeks later. Although no chemotherapy was delivered concurrently with RT, patients with pathologically positive pelvic nodes (13) or metastatic disease (6) received post-operative 5-FU based chemotherapy. All underwent fecal diversion which was closed 2-4 months post-op. Sphincter function was performed using a telephone survey according to the MSKCC sphincter function scale (Excellent: 1-2 bowel movements/day, no soilage, Good: 3-4 bowel movements/day, and/or mild soilage, fair: Episodic > 4 bowel movements/day, and/or moderate soilage, and Poor: incontinence). Actuarial calculations were performed using the Kaplan-Meier method. The median follow-up was 56 months (range: 4-121 months). RESULTS: Of the 35 patients who underwent surgery (1 pt with unresectable liver mets did not undergo surgery) (27(35)) (77%) were able to undergo a coloanal anastomosis and the pathological complete response rate was 14%. Post-operative complications included 1 (3%) partial anastamotic disruption, 2 (6%) rectal stenosis, and 1 (3%) pelvic abscess. For the total group of

  14. Optimization of the artificial urinary sphincter: modelling and experimental validation

    The artificial urinary sphincter should be long enough to prevent strangulation effects of the urethral tissue and short enough to avoid the improper dissection of the surrounding tissue. To optimize the sphincter length, the empirical three-parameter urethra compression model is proposed based on the mechanical properties of the urethra: wall pressure, tissue response rim force and sphincter periphery length. In vitro studies using explanted animal or human urethras and different artificial sphincters demonstrate its applicability. The pressure of the sphincter to close the urethra is shown to be a linear function of the bladder pressure. The force to close the urethra depends on the sphincter length linearly. Human urethras display the same dependences as the urethras of pig, dog, sheep and calf. Quantitatively, however, sow urethras resemble best the human ones. For the human urethras, the mean wall pressure corresponds to (-12.6 ± 0.9) cmH 2 O and (-8.7 ± 1.1) cmH 2 O, the rim length to (3.0 ± 0.3) mm and (5.1 ± 0.3) mm and the rim force to (60 ± 20) mN and (100 ± 20) mN for urethra opening and closing, respectively. Assuming an intravesical pressure of 40 cmH 2 O, and an external pressure on the urethra of 60 cmH 2 O, the model leads to the optimized sphincter length of (17.3 ± 3.8) mm

    1998-07-01

    Full Text Available Repair of parotid duct lacerations in 2 horses is described using intraluminal silastic tubing as a stent. The duct was lacerated traumatically at the facial vessel notch (incisura vasorum facialium in the 1st horse, and iatrogenically after removal of an intraluminal sialolith after development of infection within the duct in the 2nd horse. In both cases, a silastic tube was passed retrograde into the duct via the salivary papilla, past the wound until the end lay rostroventral to the parotid salivary gland. The severed salivary ducts and the wounds were sutured. The external portion of the silastic tube was sutured to the skin and the tube left in place. Recovery in the 1st case was uneventful. In the 2nd case a salivary duct/cutaneous fistula formed at a wound distant from the sutured wound, which healed spontaneously. This technique differs from a similar described technique in that the stent tube exits the oral cavity and is attached to the outer skin surface.

    Background: To determine if preoperative radiation therapy allows sphincter preservation in the treatment of rectal cancer. Methods: Thirty six patients with the diagnosis of invasive, resectable, primary adenocarcinoma of the rectum limited to the pelvis were enrolled on a Phase I/II trial of preoperative radiation therapy plus low anterior resection/coloanal anastomosis. By preoperative assessment, all patients had invasive tumors (5,T 2; 31,T 3 ) involving the distal half of the rectum and clinically required an abdominoperineal resection. The median tumor size was 3.8 cm [range: 1.5-7 cm] and the median distance from the anal verge was 4 cm [range: 3-7 cm]. The whole pelvis received 46.80 Gy followed by a 3.60 Gy boost to the primary tumor bed. The median follow-up was 56 months [range: 4-121 months]. Results: Of the 35 patients who underwent resection, 5 (14%) had a complete pathologic response and 27 (77%) were able to successfully undergo a low anterior resection/coloanal anastomosis. The incidence of local failure was crude: 17% and 5-year actuarial: 21%. The 5-year actuarial survival was 64%. Analysis of sphincter function using a previously published scale was performed at the time of last follow-up in the 27 patients who underwent a low anterior resection/coloanal anastomosis. Function was good or excellent in 85%. The median number of bowel movements/day was 2 (range: 0-8). Conclusions: Our data suggest that preoperative radiation therapy allows sphincter preservation in 77% of selected patients who would otherwise require an abdominoperineal resection, and 85% have good to excellent sphincter function. Given the moderate local failure rate, we now routinely use preoperative combined modality therapy plus postoperative chemotherapy for patients with clinical T 3 disease

    : Pediatric solid organ lacerations are a relatively uncommon but potentially dangerous injury that must be addressed urgently once recognized. Seen most often during recreational or team sports, they usually occur after a blunt or deceleration mechanism to the abdomen or flank. Depending on the severity of injury, solid organ laceration may not be immediately apparent clinically. This emphasizes the importance of sideline witnessing and evaluation, acting quickly once symptoms develop, and placing importance on safe sporting technique. In addition, management has changed over time to favor medical management for minor injuries, with laparotomy reserved for high-grade or hemodynamically unstable lacerations. Awareness of solid organ laceration in pediatric populations is more important than ever as they are beginning to appear in younger adolescents. Here we present a case of a 14-yr-old girl sustaining a grade IV liver laceration while playing contact team sports.

    Thirteen adult male patients who had an AS 800 artificial urinary sphincter inserted are reviewed. Five have had malfunction, and in four the causes were diagnosed radiologically. These included: fistula formation, leakage of hydraulic fluid, air in the system, and inadequate deflation of the cuff. Since the sphincter is filled with contrast medium, it is ideally suited to radiological assessment. (author). 5 refs.; 6 figs

    To evaluate whether Asian race is an independent risk factor for severe perineal lacerations. We performed a nationwide population-based retrospective cohort study examining the relationship between Asian race and severe perineal lacerations (third and fourth degree). The data were collected from the 2012 Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS). Characteristics of Asian American women were compared with those of non-Asian women. The primary outcome of interest was severe perineal lacerations. Multivariable logistic regression was used to refine the associations between Asian race and severe perineal lacerations while adjusting for confounding effects. Results were compared with previously published data using a pooled odds ratio. 2,270,044 Women with singleton vaginal deliveries were identified, and 120,452 (5.3%) were Asian. After adjusting for confounders, Asian women were more likely to experience severe perineal lacerations than any other racial group (3.5% versus 6.3%, adjusted odds ratio [aOR] 1.50, 99% CI 1.29-1.74, p literature indicated that Asian American women are 74% more likely to experience severe perineal lacerations (aOR 1.74, 99% CI 1.72-1.76, p Asians.

    2014-06-01

    The artificial urinary sphincter remains the gold standard for treatment of post-prostatectomy urinary incontinence. The AMS 800 (American Medical Systems, Minnetonka, MN, USA) is the most commonly implanted artificial urinary sphincter. Having been on the market for almost 40 years, there is an abundance of literature regarding its use, but no recent review has been published. We reviewed the current literature regarding the indications, surgical principles, outcomes and complications of artificial urinary sphincter implantation for stress urinary incontinence after prostatectomy. A PubMed search was carried out for articles on the artificial urinary sphincter from 1995 to present. The review was centered on articles related to the use of the AMS 800 for stress urinary incontinence in males after prostatectomy. Relevant articles were reviewed. The majority of patients will achieve social continence (1 pad per day) after artificial urinary sphincter implantation; however, rates of total continence (no pad usage) are significantly lower. Patient satisfaction outcomes average greater than 80% in most series. Potential complications requiring reoperation include infection (0.5-10.6%) and urethral erosion (2.9-12%). Revision surgeries are most commonly as a result of urethral atrophy, which ranges from 1.6 to 11.4%. The 5-year Kaplan-Meier freedom from reoperation ranges from 50 to 79%, while the 10-year Kaplan-Meier freedom from mechanical failure is 64%. The artificial urinary sphincter is a reliable device with good outcomes. As expected with any prosthetic device, complications including mechanical failure, infection, erosion and recurrent incontinence remain significant concerns. Despite known complications, the patient satisfaction rates after artificial urinary sphincter implantation remain high. Appropriate patient counseling and adherence to surgical principles are imperative. © 2014 The Japanese Urological Association.

    Intestinal constipation--a common symptom among the general population--is more frequent in women. It may be secondary to an improper diet or organic or functional disturbances, such as dyskinesia of the pelvic floor. This is basically characterized by the absence of relaxation or paradoxical contraction of the pelvic floor and anal sphincter during evacuation. To analyze, by manometric data, the anal pressure variation at rest, during evacuation effort by using the Valsalva maneuver and forced post-expiratory apnea in subjects with secondary constipation. Twenty-one patients (19 females--90.4%) with a mean age of 47.5 years old (23-72) were studied. The diagnosis was performed using anorectal manometry, with a catheter containing eight channels disposed at the axial axis, measuring the proximal (1) and distal (2) portions of the anal orifice. The elevation of the pressure values in relation to the resting with the evacuation effort was present in all patients. The Agachan score was used for clinical evaluation of constipation. The variables studied were: mean anal pressure of the anal orifice for 20 seconds at rest, the effort of evacuation using Valsalva maneuver and the effort of evacuation during apnea after forced expiration, as well as the area under the curve of the manometric tracing at moments Valsalva and apnea. The analysis of the mean values of the anal pressure variation at rest evidenced difference between proximal and distal channels (P = 0.007), independent of the moment and tendency to differ during moments Valsalva and apnea (P = 0.06). The mean of values of the area under the manometric tracing curve showed differences between moments Valsalva and apnea (P = 0.0008), either at the proximal portion or at the distal portion of the anal orifice. The effort of evacuation associated with postexpiratory apnea, when compared with the effort associated with the Valsalva maneuver, provides lower elevation of anal pressure at rest by the parameter area

    The dielectric elastomers are functional materials that have promising potential as actuators with muscle-like mechanical properties due to their inherent compliancy and overall performance: the combination of large deformations, high energy densities and unique sensory capabilities. Consequently, such actuators should be realized to replace the currently available artificial urinary sphincters building dielectric thin film structures that work with several 10 V. The present communication describes the determination of the forces (1 - 10 N) and deformation levels (~10%) necessary for the appropriate operation of the artificial sphincter as well as the response time to master stress incontinence (reaction time less than 0.1 s). Knowing the dimensions of the presently used artificial urinary sphincters, these macroscopic parameters form the basis of the actuator design. Here, we follow the strategy to start from organic thin films maybe even monolayers, which should work with low voltages but only provide small deformations. Actuators out of 10,000 or 100,000 layers will finally provide the necessary force. The suitable choice of elastomer and electrode materials is vital for the success. As the number of incontinent patients is steadily increasing worldwide, it becomes more and more important to reveal the sphincter's function under static and stress conditions to realize artificial urinary sphincters, based on sophisticated, biologically inspired concepts to become nature analogue.

    Workers in poultry processing and pork meatpacking have high rates of acute injuries and chronic disease among. The presence of zoonotic pathogens in these workplaces may interact with injury. We investigated incidence of worker injuries, lacerations, and infections reported by 10 companies from 2004 to 2009 and calculated annual incidence rates by industry and company along with temporal trends and job-related risk factors. Average annual mean total injury rates were 6.4 per 100 workers (poultry) and 13.2 per 100 workers (pork). Average annual mean rates for lacerations were 1.8 per 100 workers (poultry) and 1.9 per 100 (pork). Sharp tools and animal products were most frequently reported as sources for lacerations. Animal products were most frequently reported as sources of infected lacerations. The results indicate that these industries continue to have high injury rates. The results also suggest that zoonotic pathogens may be preventable health and safety risks. © 2014 Wiley Periodicals, Inc.

    Tissue adhesives are effective and yield results comparable to those with conventional suturing of superficial, linear, and low-tension lacerations. The cosmetic outcome is similar; wound complications, such as infection and dehiscence, may be lower with tissue adhesives. Wound closure of superficial lacerations by tissue adhesives is quicker and less painful compared with conventional suturing (strength of recommendation: A, systematic reviews of randomized trials).

    To examine whether episiotomy at first vaginal delivery increases the risk of spontaneous obstetric laceration in the subsequent delivery. A review was conducted of women with consecutive vaginal deliveries at Magee-Womens Hospital between 1995 and 2005, using the Magee Obstetrical Maternal and Infant database. The primary exposure of interest was episiotomy at first vaginal delivery. Multivariable polytomous logistic regression modeling of potential risk factors was used to estimate odds ratios (ORs) for obstetric laceration in the second vaginal delivery. A total of 6,052 patients were included, of whom 47.8% had episiotomy at first delivery. Spontaneous second-degree lacerations at the time of second delivery occurred in 51.3% of women with history of episiotomy at first delivery compared with 26.7% without history of episiotomy (Phistory of episiotomy at first delivery compared with 1.7% without history of episiotomy (Pdelivery after controlling for confounders. Based on these findings, for every four episiotomies not performed one second-degree laceration would be prevented. To prevent one severe laceration, performing 32 fewer episiotomies is required. Episiotomy at first vaginal delivery increases the risk of spontaneous obstetric laceration in the subsequent delivery. This finding should encourage obstetric providers to further restrict the use of episiotomy. II.

    Perineal lacerations during birth can cause ongoing physical, psychological, and social problems. However, the prevalence of lacerations following normal spontaneous vaginal birth in women with low-risk pregnancies is unknown. We investigated the prevalence of perineal lacerations and factors associated with lacerations among low-risk Japanese women who had normal spontaneous vaginal births. Pregnant women who were cared for between January 1, 2008, and June 30, 2011, in 3 midwife-led birth centers in Tokyo, Japan, where invasive medical interventions are rarely applied, were included. We investigated the prevalence of perineal lacerations and conducted univariate and multivariate analyses on the relationship between the prevalence of lacerations and selected maternal and neonatal characteristics. A total of 1881 pregnant women had initial antenatal care at one of the 3 study sites. Of these, 1521 were eligible for inclusion. Intact perineum rates were 49.5% (209/422) and 69.9% (768/1099) in nulliparous and multiparous women, respectively. First-degree lacerations occurred in 36.7% (155/422) of nulliparous women and 27.1% (298/1099) of multiparous women, and second-degree lacerations occurred in 13.5% (57/422) of nulliparous women and 3.0% (33/1099) of multiparous women. One multiparous woman experienced a third-degree laceration (0.1%). No women suffered fourth-degree or cervical lacerations. Logistic regression analyses showed that older age (≥ 35 years), the hands-and-knees position, and using a birthing chair during birth increased the risk of perineal laceration both in nulliparous and in multiparous women. In addition, waterbirths increased the risk of perineal laceration in multiparous women. In normal spontaneous vaginal births among a low-risk population, it is possible to avoid episiotomy and achieve a high rate of intact perineum, with few second-degree and third-degree lacerations. © 2015 by the American College of Nurse-Midwives.

  8. External urethral sphincter pressure measurement: an accurate method for the diagnosis of detrusor external sphincter dyssynergia?

    Directory of Open Access Journals (Sweden)

    Carlos H Suzuki Bellucci

    Full Text Available Combined pelvic floor electromyography (EMG and videocystourethrography (VCUG during urodynamic investigation are the most acceptable and widely agreed methods for diagnosing detrusor external sphincter dyssynergia (DESD. Theoretically, external urethral sphincter pressure (EUSP measurement would provide enough information for the diagnosis of DESD and could simplify the urodynamic investigation replacing combined pelvic floor EMG and VCUG. Thus, we evaluated the diagnostic accuracy of EUSP measurement for DESD. PATIENTS #ENTITYSTARTX00026;A consecutive series of 72 patients (36 women, 36 men with neurogenic lower urinary tract dysfunction able to void spontaneously was prospectively evaluated at a single university spinal cord injury center. Diagnosis of DESD using EUSP measurement (index test versus combined pelvic floor EMG and VCUG (reference standard was assessed according to the recommendations of the Standards for Reporting of Diagnostic Accuracy Initiative.Using EUSP measurement (index test and combined pelvic floor EMG and VCUR (reference standard, DESD was diagnosed in 10 (14% and in 41 (57% patients, respectively. More than half of the patients presented discordant diagnosis between the index test and the reference standard. Among 41 patients with DESD diagnosed by combined pelvic floor EMG and VCUR, EUSP measurement identified only 6 patients. EUSP measurement had a sensitivity of 15% (95% CI 5%-25%, specificity of 87% (95% CI 76%-98%, positive predictive value of 60% (95% CI 30%-90%, and negative predictive value of 56% (95% CI 44%-68% for the diagnosis of DESD.For diagnosis of DESD, EUSP measurement is inaccurate and cannot replace combined pelvic floor EMG and VCUR.

  9. Influence of hiatal hernia on lower esophageal sphincter function.

    Sliding hiatal hernia has long term been implicated as a cause of lower esophageal sphincter (LES) incompetence and gastroesophageal reflux. The physics of LES function in hiatal hernia were investigated in in vitro and in vivo experiments. In vitro models of sliding hernias were constructed from excised canine gastroesophageal specimens. A "sphincter" was simulated with a rubber band around the gastroesophageal junction. It was found that placement of a ligature "hernia ring" on the stomach increased the opening pressure of the model sphincter. Addition of a tissue "hernia sac" sutured to the esophagus above the sphincter further increased the opening pressure, the protective effect being related to the pressure transmitted from the stomach to the hernia sac. There was no fluid leakage from the hernia sac between the hernia ring and the stomach. In anesthetized dogs (in vivo model) gastric and esophageal pressures were measured during gastric infusion while the LES gas way to reflux. A ligature tied loosely around the stomach to simulate a "hernia ring" and a sliding hernia without a hernia sac increased both the opening and the closing pressures of the LES by 36 +/- 18% and 35 +/- 20% (mean +/- SD), respectively. The opening pressure was increased by a decrease in gastric wall tension at the gastroesophageal junction, which was caused by the decreased radius of the herniated portion of the stomach. Pressure transmitted from the stomach to the hernia sac added to the LES pressure, and thereby further increased the opening pressure of the sphincter. The results explain how gastroesophageal reflux may be prevented in patients with hiatal hernia. It was recognized that the hernia sac may protect the sphincter, provided that it inserts into the esophagus above the LES. PMID:7469555

    2004-01-01

    After sphincter-sparing core fistulectomy for deep anal fistula most surgeons advance a rectal mucosal flap to reinforce closure of the internal opening. Our own method having for many years been simple appositional closure the resulting series presented an opportunity for comparison. From November 1987 to January 2001, 44 patients underwent 46 core fistulectomies with flap-less direct appositional closure in our unit. Records were kept prospectively. Twenty-six fistulae (in 28 patients) appeared healed at two to five months follow-up and the patients had been discharged. A full review was mounted in May 2001, when 16 of the healed patients could be contacted and questionnaires completed. Two patients were excluded from the study. The procedure failed in 16 patients initially and was found to have done so in two more at long-term follow-up (41% overall). Three patients had died and five could not be traced. Simple appositional closure after core fistulectomy for deep anal fistula seems inferior to methods using flap reinforcement.

    Anal canal carcinoma are highly curable by irradiation, combined with chemotherapy in locally advanced disease, with preservation of sphincter function. The clinical target volume for the nodes is extended, often including the inguinal nodes, which is not usual for other pelvic tumours. Acute and late effects are correlated with the volume and dose delivered to organs at risk, i. e. small bowel, bladder and increased by concomitant chemotherapy. Intensity modulated irradiation (IMRT) makes it possible to optimize the dose distribution in this 'complex U shaped' volume, while maintaining the dose distribution for the target volumes. The conversion from conformal irradiation to IMRT necessitates good knowledge of the definition and skills to delineate target volumes and organs at risk, including new volumes needed to optimize the dose distribution. Dosimetric and clinical benefits of IMRT are described, based on early descriptions and evidence-based publication. The growing development of IMRT in anal canal radiotherapy must be encouraged, and long-term benefits should be soon published. Radiation oncologists should precisely learn IMRT recommendations before starting the technique, and evaluate its early and late results for adverse effects, but also for long-term tumour control.

    Faecal incontinence is a physically, psychologically and socially disabling condition. NICE guidance (2007) recommends surgical intervention, including sacral nerve stimulation (SNS), after failed conservative therapies. The FENIX magnetic sphincter augmentation (MSA) device is a novel continence device consisting of a flexible band of interlinked titanium beads with magnetic cores that is placed around the anal canal to augment anal sphincter tone through passive attraction of the beads. Preliminary studies suggest the FENIX MSA is safe, but efficacy data is limited. Rigorous evaluation is required prior to widespread adoption. The SaFaRI trial is a National Institute of Health Research (NIHR) Health Technology Assessment (HTA)-funded UK multi-site, parallel group, randomised controlled, unblinded trial that will investigate the use of the FENIX MSA, as compared to SNS, for adult faecal incontinence resistant to conservative management. Twenty sites across the UK, experienced in the treatment of faecal incontinence, will recruit 350 patients randomised equally to receive either SNS or FENIX MSA. Participants will be followed-up at 2 weeks post-surgery and at 6, 12 and 18 months post-randomisation. The primary endpoint is success, as defined by device in use and ≥50 % improvement in the Cleveland Clinic Incontinence Score (CCIS) at 18 months post-randomisation. Secondary endpoints include complications, quality of life and cost effectiveness. SaFaRI will rigorously evaluate a new technology for faecal incontinence, the FENIX™ MSA, allowing its safe and controlled introduction into current clinical practice. These results will inform the future surgical management of adult faecal incontinence.

    Seventy-five doctors completed a questionnaire documenting their grade, specialty, and experience in performing digital rectal examination (DRE). A model anus, using a pressure transducer surrounding an artificial canal, was assembled and calibrated. Participants performed 4 DREs on the model (with a break between attempts) and predicted tone as "reduced" or "normal" (35 and 60 mm Hg, respectively), followed by a "squeeze" test. Thirty health care assistants partook as a control group with no training in DRE. Our main objective was to investigate the validity of digital rectal examination (DRE) for assessment of anal tone. Cauda equina syndrome represents the constellation of symptoms and signs resulting from compression of lumbrosacral nerve routes. Combined with subjective neurological findings, a reduction in anal tone is an important sign, deeming further imaging necessary. DRE is an invasive procedure used to assess anal tone despite debated accuracy. A total of 75 doctors from various specialties were asked to fill in a questionnaire detailing their grade, age, and area of expertise. In addition, information was gathered with regard to prior training in performing DRE to assess anal tone and the importance placed on any findings. Thirty hospital health care assistants (HCAs) were used as a control group. HCAs were selected as a control group because they receive no training on the technique and would never be required to perform it in their clinical practice. A model anus was assembled using a modified pediatric sphygmomanometer cuff to act as a sphincter. The cuff could be inflated to simulate a full range of anal tone. The cuff was incorporated into an artificial anal canal, which was, in turn, placed into a model buttock created from plaster of Paris. The apparatus was calibrated across a range of pressures. In each attempt, 60%, 61%, 63%, and 67% of doctors correctly identified the anal tone, respectively (average accuracy: 64%). HCAs had an identical

    Over the years from 1992 to 1997, 41 anorectal malformations (ARM) with histopathologic alterations were investigated to determine which morphologic abnormalities of the distal rectum accompany ARMs. Three other cases showed normal neuromuscular morphology; 9 further cases could not be evaluated owing to scanty biopsies. All resected specimens were caudocranially coiled and cryostat cut at -20 degrees C into serial sections, which were stained with a lactic dehydrogenase, succinic dehydrogenase, nitroxide synthase, and acetylcholinesterase reaction as well as hemalum and sirius red. Ten low, 15 intermediate, and 10 high forms of anal atresia (AA) were studied. In addition, six cloacal abnormalities were investigated. In 7 cases (17%) (5 intermediate, 2 low AAs), the characteristics of Hirschsprung's disease were observed. Oligoneuronal hypoganglionosis of the myenteric plexus proximal to the anal floor was diagnosed in 7 AAs (12%). In 10 children with high-type AA and resection of 1-5 cm distal rectum and in all cloacal anomalies (n = 6) defects of the muscularis propria were seen in the rectal-atresia sac. These defects were characterized by hypoplasia of the circular-muscle layer and/or the internal anal sphincter (IAS). Intestinal neuronal dysplasia of the submucous plexus was most frequently observed (12%) in high-type AA. A correlation between innervation anomalies or anomalies of the muscularis propria and the type of fistula could not be seen. In conclusion, all cases with high-type AA and cloacal anomalies were characterized by anomalies of the muscularis propria and/or IAS but this was not the case in intermediate and low-type AAs. Anomalies of the enteric nervous system were diagnosed in 60% of AAs.

    The defecation disorders represents the 3% of consultations in pediatrics patients. Our goal was to demonstrate the effectiveness and efficiency of the reeducation of the defecation maneuver through home training in patients with encopresis and sphincter dyssynergia. Study of patients with fecal incontinence treated with home training at our center between 2014-2015. Anorectal manometry was performed and was valued defecation maneuver by expulsion of rectal probe with or without the ball. Daily sessions were performed using a Foley catheter (18-20Fr.) with progressive filling of the balloon, maximum 20cc. The response to the treatment was assessed in terms of episodes of soiling. Seven patients (6 males and 1 female) with a mean age of 9.7 years (range, 5-15) were included; two patients with anorectal malformation history, 1 Hirschsprung disease, 1 sacrococcygeal teratoma and 3 functional encopresis. Three patients had soiling episodes daily and 4 patients frequently. The mean basal pressure of anal channel was 32.34mmHg (range, 11.74-50.75) with negative defecation maneuver in 2 cases, deficient in 3 and dyssynergic in 2 patients. The mean time of biofeedback therapy to be asymptomatic was 5.14 months (range, 2-11), with a mean of 16.14 months (range, 3-24), with the 7 patients currently maintained clean. The present study suggests that re-education of defecation maneuver through home training, seems to be an effective and efficient therapy, achieving excellent results in medium term.

    Accident-induced liver trauma is a significant human health concern, as this organ is readily injured during periods at which the abdominal region is compromised. In this work, electromagnetic thermotherapy was successfully developed and employed in vitro and in vivo to treat livers that had been lacerated. Briefly, a new hemostasis plug was integrated with an electromagnetic thermotherapy system (ETS) to perform surgery on lacerated livers. The high-frequency, alternating electromagnetic field (EMF) was generated by the ETS and was shown to induce a pre-set temperature increase within the hemostasis plug embedded in the target tissue. In order to prevent overheating and maintain a constant hemostasis temperature, a temperature feedback control system was utilized. The effect of the intensity of the EMF on the heating capacity of the ETS-hemostasis system was first explored. Furthermore, the relationship between the coagulation zone and operating temperature were investigated in vitro. By utilizing the temperature feedback control system, the hemostasis plug could be heated to a specific temperature for efficient hemostasis. With this approach, the optimal treatment temperature and time were investigated for liver laceration. Lacerated livers from New Zealand white rabbits were successfully treated with the hemostasis plug and ETS within a short period of time. When compared with the traditional perihepatic packing approach, the volume of blood loss from liver laceration surgeries treated by ETS has been dramatically reduced by 83%, suggesting a high therapeutic potential for this system.

    Information is accumulating on exceptional cases of oily orange anal leakage, probably caused by certain foods and their form of consumption. The leakage is usually inadvertent and is worrisome for patients. Clinical data was gathered on a case series presenting with massive and inadvertent orange oily anal leakage, without sphincter sensation, causing the patients to feel alarmed. This condition usually occurs after eating fish, especially Japanese cuisine. Eleven patients were included (four women and seven men). The mean age was 47.3 years. Colonoscopy had previously been performed in four patients, with normal results. The symptoms, described as keriorrhea, were probably produced by accumulation of indigestible "wax esters", es Mero present in some oily fish, recently incorporated in raw fish dishes (sashimi) or as Japanese Mero sea bass. These oils, which cannot be absorbed or digested, accumulate in the rectum and may also filter spontaneously and induce toxin-related sphincter dysfunction. The same symptoms are sometimes produced after consumption of cooked versions of these species. The diagnosis is given by clinical data, prior ingestion of these types of fish and the self-limiting nature of the symptoms, without the need for further investigations. We describe a case series of a recently described entity associated with dietary changes. This entity is benign and self-limiting. Clinicians should be familiar with the symptoms to inform patients correctly and avoid unnecessary laboratory studies. Copyright © 2011 Elsevier España, S.L. All rights reserved.

    To investigate the application of gluteus maximus transplantation for fecal incontinence after surgery of high anal atresia. Between December 2002 and November 2010, 25 patients with fecal incontinence were treated with gluteus maximus transplantation, which was caused by surgery of high anal atresia. There were 11 males and 14 females with an average age of 10.2 years (range, 3-22 years). Preoperative radiography, anorectal manometer, and electromyogram showed abnormality or deficiency of anal sphincter function. Wexner score, Fecal Incontinence Quality of Life (FIQL) questionnaire, and Self-rated Health Measurement Scale Version 1.0 (SRHMS) score were used to evaluate life quality of the patients. The anorectal manometer, intra-rectal ultrasound examination, and defecation radiography were performed. Healing of incision by first intention was achieved in 23 cases and rectal-wound fistula occurred in 2 cases. The follow-up time was 1 to 9 years (mean, 6.3 years). Defecation frequency was decreased from more than 10 times to 4-6 times every day. Wexner score and SRHMS were significantly improved at 1 or 2 years after surgery when compared with preoperative socres (P Gluteus maximus transplantation can improve defecation controls in the patients with fecal incontinence after surgery of high anal atresia.

    Injuries caused by glass occur frequently, in particular in children, and make up an estimated 3% to 5% of all emergency visits, most frequently involving lacerations of hands, feet, and face. About 30% to 40% of glass injuries occur at home and often involve so-called architectural glass or bottles and glass containers. Accidents reported in association with showering mostly refer to falls or scalding by hot water. However, an increasing number of shower screens are made of tempered glass, which may potentially brake. Such injuries may be potentially severe, causing laceration of extremity arteries; requiring hospitalization or outpatient treatment for injuries; causing absence from work. These injuries are likely underreported in the medical literature but could have potential medicolegal consequences for the patient. We report a case of multiple lacerations developed in a third-trimester pregnant woman caused by the spontaneous shattering of a shower screen glass and discuss the apparent unawareness to this potential hazard in the scientific literature.

    Blow-out fracture and canalicular laceration can occur simultaneously as a result of the same trauma. Despite its importance, little research has been conducted to identify clinical characteristics or surgical techniques for repair of a blow-out fracture accompanied by canalicular laceration. The aim of this study was to evaluate the clinical characteristics, the surgical approach, and the outcomes. Thirty-four eyes of 34 patients who underwent simultaneous repair of canalicular laceration using silicone tube intubation and reconstruction of blow-out fracture were included. Medical records were retrospectively reviewed for patient demographics, nature of injury, affected canaliculus, location, and severity of blow-out fracture, associated facial bone fracture, ophthalmic diagnosis, length of follow-up period, and surgical outcome. Mean patient age was 40.0 years (range, 17-71 y). The mean follow-up was 7.3 months. Fist to the orbital area (10 patients, 29.4%) was the most common cause. There were 24 lower canalicular lacerations (70.6%), 6 upper canalicular lacerations (17.6%), and 4 upper and lower canalicular lacerations (11.8%). Isolated medial wall fractures were most common (area A4: 20/34, 58.8%). Fractures involving both the floor and medial wall and maxillo-ethmoidal strut (areas A1, A2, A3, and A4) were the second most common (6/34, 17.6%), and floor and medial wall with intact strut (areas A1, A2, and A4) were injured in 6 patients (17.6%). Pure inferior wall fractures were least frequent (areas A1 and A2: 2/34, 5.9%). The severity of the fracture was severe in most patients except for 1 linear fracture with tissue entrapment and 1 moderate medial wall fracture (32/34, 94.1%). There was lid laceration in 20 patients (58.8%). Nasal bone fracture (5/34, 14.7%) was the most common facial bone fracture. Tubes were removed at a mean of 3.3 months (range, 3-4 mo). In total, 31 patients (91.2%) achieved complete success in canalicular laceration and blow

    Lacerations to the extensor mechanism are usually diagnosed clinically. Ultrasound (US) has been a growing diagnostic tool for tendon injuries since the 1990s. To date, there has been no publication establishing the accuracy and reliability of US in the evaluation of extensor mechanism lacerations in the hand. The purpose of this study is to determine the accuracy of US to detect extensor tendon injuries in the hand. Sixteen fingers and 4 thumbs in 4 fresh-frozen and thawed cadaveric hands were used. Sixty-eight 0.5-cm transverse skin lacerations were created. Twenty-seven extensor tendons were sharply transected. The remaining skin lacerations were used as sham dissection controls. One US technologist and one fellowship-trained musculoskeletal radiologist performed real-time dynamic US studies in and out of water bath. A second fellowship trained musculoskeletal radiologist subsequently reviewed the static US images. Dynamic and static US interpretation accuracy was assessed using dissection as "truth." All 27 extensor tendon lacerations and controls were identified correctly with dynamic imaging as either injury models that had a transected extensor tendon or sham controls with intact extensor tendons (sensitivity = 100%, specificity = 100%, positive predictive value = 1.0; all significantly greater than chance). Static imaging had a sensitivity of 85%, specificity of 89%, and accuracy of 88% (all significantly greater than chance). The results of the dynamic real time versus static US imaging were clearly different but did not reach statistical significance. Diagnostic US is a very accurate noninvasive study that can identify extensor mechanism injuries. Clinically suspected cases of acute extensor tendon injury scanned by high-frequency US can aid and/or confirm the diagnosis, with dynamic imaging providing added value compared to static. Ultrasonography, to aid in the diagnosis of extensor mechanism lacerations, can be successfully used in a reliable and

    Full Text Available Introduction: Cleft lip and palate are common congenital abnormalities with typical functional disorders on speech, deglutition and middle ear function. Objective: This article reviews functional labiopalatine disorders through a pathophysiological view. Method: We performed a literature search on line, as well as books and periodicals related to velopharyngeal sphincter. Our sources were LILACS, MEDLINE and SciELO databases, and we applied to the research Keywords of interest on the velopharyngeal pathophysiology, for articles published between 1965 and 2007. Conclusion: Velopharyngeal sphincter plays a central role in speech, swallowing and middle ear physiology in patients with labiopalatine cleft. At the end of our bibliographic review, pursuant to the velopharyngeal physiology in individuals with this disorder in the functional speech, deglutition and otologic function, we observed that although there is a great number of published data discussing this issue, further studies are necessary to completely understand the pathophysiology, due to the fact they have been exploited superficially.

    Artificial urinary sphincter (AUS) is regarded as the gold standard treatment for post-prostatectomy urinary incontinence. Kidney transplantation is gold standard treatment for end stage renal disease. Since both AUS implantation and renal transplant surgeries are relatively common, a co-occurrence is likely and a patient with AUS may need a kidney transplant. Herein, we report a patient with an AUS who underwent second kidney transplantation. Since the iliac fossa ipsilateral to the AUS part...

    Main endpoint was a response rate to therapy; secondary endpoints were disease-free survival, overall survival, acute and late toxicities, specially in terms of anorectal and urinary continence. Radiochemotherapy for anal cancer achieves a good clinical response, locoregional control, anal function preservation. However, oncologic outcomes can differ using radiotherapy plus fluorouracil and mytomicin vs. cisplatin and fluorouracil. Between 2000 and 2012, 27 anal cancer patients receiving radiotherapy combined with two different radiochemotherapy schedules, fluorouracil and mytomicin (group A) and cisplatin plus fluorouracil (group B). The Kaplan-Meier method was also used to estimate local control, overall survival and disease free survival. Statistical significance between curves was evaluated using the Log-rank test. Complete pathological response was found in 85.2% of patients, with higher rates of response in the group A (100% vs. 63.6%, p = 0.039). No significantly difference was found between the two groups for the other endpoints. Low rates of both acute and late toxicities were recorded. Radiotherapy plus fluorouracil and mytomicin provide a better complete pathological response than radiotherapy plus cisplatin and fluorouracil and a greater rate of anal sphincter function preservation. Globally, radiochemotherapy of the anal cancer provides excellent clinical outcomes with a good profile of acute and late toxicity, without difference between the two groups studied.

    Organ shortage is the main bottleneck in the wait-list for transplantation; therefore, expanding the donor pool is an effective way to solve the problem. Usage of the traumatized liver for transplantation has been applied, but the use of lacerated kidneys for transplant donor is rarely reported. We reported a successful case of donation after brain death. The donor committed suicide by jumping from a campus dormitory building. One of the donated kidneys was severely injured. Two lacerations measured 4 × 1 × 1 cm in the medial margin of the graft and 1 × 1 × 1.5 cm in the front side of the graft, respectively. After repair with continuous absorbable suture, the lacerated kidney was transplanted to a recipient. The post-transplantation renal function gradually recovered. Furthermore, serious complications, such as large amounts of hemorrhage, delayed graft function, or urinary fistula did not occur. The serum creatinine dropped from 1232 μmol/L to 120 μmol/L and maintained normal range after surgery. In addition, the daily urine output was normal. At day 12 after operation, the patient was discharged. Our case shows that the use of a lacerated donor kidney appears to be feasible, but long-term effects need further observation.

    Full Text Available AIM: To investigate the epidemiology and surgical outcomes of old canalicular laceration and analyze the variables impacting on the prognosis of reparation. METHODS: A retrospective review of all old canalicular laceration repairs from Jan. 1, 2008 to Dec. 30, 2015 was performed. Analyzed data included demographics, mechanisms of injury, the time from injury to repair, causes for delayed repair, old associated injuries, the types of surgery, and the effects of repair using canaliculus anastomosis combined with bicanalicular stent intubation. RESULTS: Totally 148 patients with old canalicular laceration received surgical repair and were enrolled. The mean age at presentation was 32.52 years old (ranged from 3 to 63 years old. The 110 patients (74.32% were male and 127 patients (85.81% were adults (≥18 years old. The old upper, lower, and bicanalicular lacerations were found in 5 (3.38%, 39 (26.35%, and 104 patients (70.27%, respectively. The mechanism of old injury was primarily due to motor vehicle accidents (n=53, 35.81%. The mean time from injury to repair was 43.61mo (ranged from 1 to 360mo. Associated old ocular and orbit injuries were found in 65 patients (43.92%, and chronic dacryocystitis in 18 patients (12.16%. The main cause of delayed repair was that doctors or patients didn’t pay attention to the canalicular laceration because of the concurrent severe injuries (n=71, 47.97%. Totally 136 patients (91.89% with old canalicular laceration underwent canaliculus anastomosis combined with bicanalicular stent intubation. In all of them, 20 patients (13.51% were combined with dacryocystorhinostomy.

    This prospective, randomized, controlled trial was designed to compare the clinical, functional, and morphologic results of pneumatic balloon dilatation with lateral internal sphincterotomy for the treatment of chronic anal fissure. All patients with symptomatic chronic anal fissure were randomly assigned to pneumatic balloon dilatation or lateral internal sphincterotomy and invited to complete a standardized questionnaire inquiring about their symptoms. Anal ultrasonography and anal manometry were performed before and six months after surgery. A proctologic examination was performed between the fifth and sixth postoperative weeks. Anal continence, scored by using a validated continence grading scale, was evaluated preoperatively at 1 and 6 weeks and at 12 and 24 months. Fifty-three patients, who satisfied selection criteria, were enrolled in the trial. Four patients (7.5 percent) were lost to follow-up. Twenty-four patients (11 males; mean age, 42 +/- 8.2 years) underwent pneumatic balloon dilatation and 25 patients (10 males; mean age, 44 +/- 7.3 years) underwent lateral internal sphincterotomy. Fissure-healing rates were 83.3 percent in the pneumatic balloon dilatation and 92 percent in the lateral internal sphincterotomy group. Recurrent anal fissure was observed in one patient (4 percent) after lateral internal sphincterotomy. At anal manometry, mean resting pressure decrements obtained after pneumatic balloon dilatation and lateral internal sphincterotomy were 30.5 and 34.3 percent, respectively. After pneumatic balloon dilatation, anal ultrasonography did not show any significant sphincter damage. At 24-month follow-up, the incidence of incontinence, irrespective of severity, was 0 percent in the pneumatic balloon dilatation group and 16 percent in the lateral internal sphincterotomy group (P < 0.0001). As lateral internal sphincterotomy, pneumatic balloon dilatation grants a high anal fissure-healing rate but with a statistically significant reduction in

    Full Text Available Objective: to assess the efficiency of endorectal ultrasound (ERUS in the study of chronic idiopathic anal pain (CIAP. Material and method: this is a prospective and descriptive study in which 40 patients, 18 men and 22 women with an average of 47 years, were included. They had chronic anal pain of at least 3 months' duration. A complete colonoscopy was performed in all patients, which found no abnormalities to explain clinical symptoms. Patients with anal fissure and internal hemorrhoids of any degree, perianal suppurative processes, and pelvic surgery were excluded from the study. An ALOKA ProSound SSD-4000 ultrasound console attached to a multifrequency radial transductor ASU-67 (7.5 and 10 MHz was used. Results: one patient could not tolerate the examination. In 8 patients (20% of cases alterations were detected during ultrasonography: in 4 patients (10% of the cases; 1 man and 3 women internal anal sphincter (IAS hypertrophy, and in 5 patients (4 women and 1 man a torn sphincter complex. A tear in the upper IAS canal and hypertrophy of the middle anal canal were observed in one patient (1 woman. Conclusions: ERUS is a simple, economic and useful test to study anorectal pathologies. Although in most studied cases no damage to the anal canal or rectal wall was detected, in a considerable number of patients we observed a thickening of the IAS, a probable cause of anal pain.

    Purpose: The aim of the present study was to compare the influence of preoperative chemoradiotherapy (CRT) with postoperative CRT on the incidence and types of postoperative complications in rectal cancer patients who underwent sphincter-saving resection. Patients and Methods: We reviewed 285 patients who received preoperative CRT and 418 patients who received postoperative CRT between January 2000 and December 2006. Results: There was no between-group difference in age, gender, or cancer stage. In the pre-CRT group, the mean level of anastomosis from the anal verge was lower (3.5 ± 1.4 cm vs. 4.3 ± 1.7 cm, p < 0.001) and the rate of T4 lesion and temporary diverting ileostomy was higher than in the post-CRT group. Delayed anastomotic leakage and rectovaginal fistulae developed more frequently in the pre-CRT group than in the post-CRT group (3.9% vs. 1.2%, p = 0.020, 6.5% vs. 1.3%, p = 0.027, respectively). Small bowel obstruction (arising from radiation enteritis) requiring surgical intervention was more frequent in the post-CRT group (0% in the pre-CRT group vs. 1.4% in the post-CRT group, p = 0.042). Multivariate analysis identified preoperative CRT as an independent risk factor for fistulous complications (delayed anastomotic leakage, rectovaginal fistula, rectovesical fistula), and postoperative CRT as a risk factor for obstructive complications (anastomotic stricture, small bowel obstruction). The stoma-free rates were significantly lower in the pre-CRT group than in the post-CRT group (5-year stoma-free rates: 92.8% vs. 97.0%, p = 0.008). Conclusion: The overall postoperative complication rates were similar between the pre-CRT and the Post-CRT groups. However, the pattern of postoperative complications seen after sphincter- saving resection differed with reference to the timing of CRT.

    Objective: To evaluate the development of the sphincter muscle complex (SMC) and defecation function in pediatric patients with congenital anorectal malformations (ARM). Methods: A total of 64 children underwent MRI, among whom 39 were patients with ARM, and the others were patients without ARM undergoing MRI because of other dieases. The dimensions of the SMC in different planes were evaluated with different sequences and coils. The relationship between the SMC development and the defecation function was investigated. Results: In control group, the absolute value of SMC width was (3.63 ± 0.22)mm, which had a high correlation with age (r=0.998, P 0.05). The SMCs in intermediate ARM patients [muscle index (MI)=0.47 ± 0.05] and low ARM patients (MI=0.49 ± 0.05) were well developed. The SMCs in a portion of patients with high ARM (MI=0.28 ± 0.06) were poorly developed, when MI≤0.18, anorectal contraction pressure was significantly lower (t=3.55, P 0.18[(0.85 ± 0.20) vs (2.24 ± 1.02) kPa]. The length of anal canal with high-pressure[(10.88 ± 3.64) vs (20.26 ± 4.34)mm] was shorter (t= 5.18, P 0.18, the anorectal angle was less than 90 degrees, and normal continent function was found in 21 of 23 cases (91%). Conclusion: MRI can be employed to evaluate the development of SMC in patients with ARM, MI was an objective criteria to evaluate the development of SMC. When MI≤0.18, maldevelopment of SMC will be highly suspected. (authors)

  15. Variation of the anal resting pressure induced by postexpiratory apnea effort in patients with constipation

    Full Text Available CONTEXT: Intestinal constipation - a common symptom among the general population - is more frequent in women. It may be secondary to an improper diet or organic or functional disturbances, such as dyskinesia of the pelvic floor. This is basically characterized by the absence of relaxation or paradoxical contraction of the pelvic floor and anal sphincter during evacuation. OBJECTIVE: To analyze, by manometric data, the anal pressure variation at rest, during evacuation effort by using the Valsalva maneuver and forced post-expiratory apnea in subjects with secondary constipation. METHODS: Twenty-one patients (19 females - 90.4% with a mean age of 47.5 years old (23-72 were studied. The diagnosis was performed using anorectal manometry, with a catheter containing eight channels disposed at the axial axis, measuring the proximal (1 and distal (2 portions of the anal orifice. The elevation of the pressure values in relation to the resting with the evacuation effort was present in all patients. The Agachan score was used for clinical evaluation of constipation. The variables studied were: mean anal pressure of the anal orifice for 20 seconds at rest, the effort of evacuation using Valsalva maneuver and the effort of evacuation during apnea after forced expiration, as well as the area under the curve of the manometric tracing at moments Valsalva and apnea. RESULTS: The analysis of the mean values of the anal pressure variation at rest evidenced difference between proximal and distal channels (P = 0.007, independent of the moment and tendency to differ during moments Valsalva and apnea (P = 0.06. The mean of values of the area under the manometric tracing curve showed differences between moments Valsalva and apnea (P = 0.0008, either at the proximal portion or at the distal portion of the anal orifice. CONCLUSION: The effort of evacuation associated with postexpiratory apnea, when compared with the effort associated with the Valsalva maneuver, provides

    Seventy-five Mallory-Weiss lacerations were visualized endoscopically in 58 of 528 patients evaluated acutely for upper gastrointestinal bleeding. The Mallory-Weiss mucosal laceration is more common than generally recognized, is usually associated with hiatal hernia and a prodrome of retching or vomiting, and the ingestion of alcohol or acetylsalicyclic acid, or both. The lacerations are most commonly gastric and are associated with other mucosal lesions which may in fact be the instigating cause of the retching and vomiting. Although blood loss may be considerable, 90% or more patients with this lesion can be managed nonsurgically with appropriate blood component replacement and occasional use of systemic pitressin. There was one fatality in this series of 58 patients with Mallory-Weiss lacerations.

    Full Text Available Various topical anti-microbial agents are used for lacerated wounds. The reports on the efficacy of these agents in healing the wounds are not comprehensive. This study reviews the results of seven topical antimicrobial agents applied under sterile occlusive dressing of superficial lacerated wounds in children. All the patients were given P.O. amplicillin for five days. Healing rate of 100% was achieved with framycetin, gention violet paint, mercurochrome paint and povidone iodine with 4-6 days of treatment; whereas only 56.25%, 66.66% and 54.55% wound healing were observed with nitrofurazone, polymixin + neomycin + bacitracin and silver sulphadiazine respectively. The nonheating wounds in the latter group when subjected to an application of the agents that showed 100% healing, heated in another 5-6 days.

    Full Text Available Thoracic complications belong to exostosis with the other abnormality are extremely rare. A 40 year-old man presented with right-sided pleuritic chest pain. Computed tomographic scan of the chest revealed exostosis length 2.5 cm pushing pleura and diaphragm and compressing adjacent to lung and liver. Middle and lower lobe bronchiectasis was also identified. There were a web lesion in bronchial lumen at the level of middle lobe at bronchoscopy. In operation, diaphragm lac-eration was repaired with sutures. Bilobectomy inferior was performed and 10th costa was partially resected together with exostosis. Exostosis cases which lead to diaphragm laceration and bronchiectasis in addition with bronchial web as we present in this case are quite rare.

    Full Text Available The published evidence concerning the safety, efficacy, and patient satisfaction for implantation of the current model of the artificial urinary sphincter (AS 800 in men with post prostatectomy urinary incontinence was the objective of this review. A Pub Med English language literature search from 1995 to 2011 was performed. A majority of men who undergo AUS implantation for post prostatectomy urinary incontinence achieve satisfactory results (0 to 1 pad per day. Infection rates range from 0.46 to 7%, cuff erosion rates range from 3.8 to 10%, and urethral atrophy ranges from 9.6 to 11.4%. Kaplan-Meier 5 year projections for freedom from any reoperation were 50% for a small series and 79.4% for a larger series. Kaplan-Meier projections for freedom from mechanical failure were 79% at 5 years and 72% at 10 years. In another series 10 year projections for freedom from mechanical failure were 64%. Although the artificial urinary sphincter (AUS is the gold standard for the treatment of this disorder, most men will continue to need at least one pad per day for protection, and they are subject to a significant chance of future AUS revision or replacement.

    Erectile dysfunction (ED) and stress urinary incontinence (SUI) from urethral sphincteric deficiency is not an uncommon problem. The commonest etiology is intervention for localized prostate cancer and/or radical cystoprostatectomy for muscle invasive bladder cancer. Despite advances in surgical technology with robotic assisted laparoscopic prostatectomy and nerve sparing techniques, the rates of ED and SUI remain relatively unchanged. They both impact greatly on quality of life domains and have been associated with poor performance outcomes. Both the artificial urinary sphincter and penile prosthesis are gold standard treatments with proven efficacy, satisfaction and durability for end-stage SUI and ED respectively. Simultaneous prosthesis implantation for concurrent conditions has been well described, mostly in small retrospective series. The uptake of combination surgery has been slow due in part to technical demands of the surgery and to an extent, a heightened anxiety over potential complications. This paper aims to discuss the technical aspect of concurrent surgery for both disease entity and the current published outcomes of the various surgical techniques with this approach. PMID:23202702

    Full Text Available Methods of macromicroscopy and morphometry have been used to study sphincter zone glands by 54 total preparations of a urinary bladder received from corpses of people of different ages without any pathology of organs of urine-genital apparatus. The glands were painted by 0, 05% methylene blue solution and were investigated with the application of stereomicroscopic-binocular microscope MBS-9. Microscopic sections of sphincter zone glands in the thickness 5-7 microns were stained with hematoxylin-eosin, azure-2-eosin and with hematoxylin-picrofucsin by Van-Gizon technique. Sphincter zone glands are arranged firmly without dependence on age, length and width of initial department of glands of these zones. In postnatal ontogenesis size indices of sphincter zone glands have been essentially changed. These indices are equal for left and right ureter sphincter zone glands

Sixty-seven cases of anal pain ocurred in patients with previous perineal or pelvic surgery: anal fissure (48, hemorrhoidectomy (12, episiotomy (4, fistula (2, and prostatectomy (1. After fissure surgery, incomplete sphincterotomy was the first cause of anal pain. Twenty-eight patients had no previous surgery, and more than 57.14% of them were found to have internal anal sphincter hypertrophy. Conclusions: patients with anal pain can be studied by endoanal ultrasounds in spite of the use of an endoprobe. With this exploration a cause of pain is found in 81.93% of cases. Internal anal sphincter hypertrophy is the most frequent finding associated with spontaneous anal pain.

    Full Text Available Hemothorax is a rare but potentially fatal postthoracentesis complication. Early clinical signs may be nonspecific resulting in diagnostic delay. A high index of suspicion is vital for early diagnosis and intervention to avoid further bleeding. Following procedure, early bedside ultrasound findings can be vital for early detection. We report a case of massive hemothorax in a 63-year-old male following therapeutic thoracentesis. Diagnosis was made following highly suggestive sonographic findings prompting thoracotomy and lacerated intercostal artery cauterization.

    Case report. Tendon lacerations of the hallux are potentially devastating to a dancer. Strength of the hallux musculature is necessary to attain and maintain balance, push-off in multiple turns, and decelerate in jumps and hops. The purpose of this paper is to report on the repair and rehabilitation of extensor hallucis longus and extensor hallucis brevis tendon lacerations in a professional dancer. A 30-year-old dancer sustained complete laceration of her extensor hallucis longus and extensor hallucis brevis tendons, and partial laceration of the dorsal aspect of the hallux metatarsophalangeal (MTP) joint capsule. Following primary repair, at 9 weeks postsurgery, hallux MTP joint active dorsiflexion was limited to 5 degrees and passive dorsiflexion to 70 degrees . First toe dorsiflexion and plantar flexion strength was 4/5 at the MTP and 3+/5 at the interphalangeal joint. Rehabilitation included functional electrical stimulation to address considerable calf atrophy, strengthening exercises, functional retraining, and progressive return to dance. The dancer returned to her previous level of dancing in 18 weeks, with 73 degrees and 85 degrees of hallux MTP joint active and passive dorsiflexion, and 30 degrees and 35 degrees of active and passive plantar flexion, respectively. Hallux MTP and interphalangeal joint muscle strength were 5/5 and 4+/5, respectively. Improvement, manifested in her SF-36 and Dance Functional Outcome System scores, accompanied her full functional recovery. Hallux stability provided by coactivation of the great toe extensors and flexors is crucial to accomplish the demands of bipedal and unipedal balances and activities in dance. This report demonstrates the success of primary surgical repair and rehabilitation in a dancer/athlete experiencing this injury.

    The glycolipid biosurfactants mannosylerythritol lipids (MELs) attract great attention for their biodegradability, super emulsifying properties and versatile bioactivities. In this study, the MEL deriving from Ceriporia lacerate CHZJU was identified as MEL-A, and its critical micelle concentration and emulsifying activities were assessed. To examine the production of MELs from Ceriporia lacerate, a Plackett-Burman design and response surface methodology were used to optimize the culture nutrients. The optimal medium contains 1g/L yeast extract, 1.5g/L (NH 4 ) 2 SO 4 , 0.5g/L KH 2 PO 4 , 0.04g/L CaCl 2 , 119.6mL/L soybean oil and 0.297g/L MnSO 4 . Subsequent verification revealed that the yield of MELs was 129.64±5.67g/L. Furthermore, an unstructured kinetic model was developed for mycelial growth, MEL production and substrate utilization. This work provides insight into Ceriporia lacerate CHZJU, a predominant fungus producing MEL-A. Optimization using response surface methodology enhanced the mannosylerythritol lipid recovery. Importantly, we developed fermentation kinetic modelling for mannosylerythritol lipid production. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Treatment for anal fistulas in patients with Crohn's disease is still challenging, even for the expert surgeon. The advancement flap technique is characterized by the preservation of the anal sphincter complex. A systematic review of the literature, selecting series of patients affected by Crohn's disease and anal fistulas and treated using advancement flap technique was performed. Patients followed during at least 6 months have been included. From 128 initial studies, 11 studies were selected, including overall 135 patients. Those studies show low- level evidence. Results in a series with follow-up from 8,4 to 82 months, stated a clinical success of 66% and recurrence rate around 30%. However there was an evident heterogeneity of results. The review concludes that the advancement flap technique to treat anal fistulas in patients with Crohn's disease is an adequate alternative. New studies are necessary to provide higher-level evidence. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    PURPOSE: The advent of effective non-operative treatment for anal carcinoma with combined chemotherapy and radiation (CRT) has obviated the need for permanent colostomy in the majority of such patients. However, little is known about the long-term functional outcome of patients treated in this manner. The purpose of this analysis was to assess the outcome, including sphincter function and late toxicity, among anal cancer patients treated with definitive CRT. PATIENTS and METHODS: From 1978 to 1995, 47 anal cancer patients received CRT with curative intent at Thomas Jefferson University Hospital. Radiation (RT) dose to the primary tumor ranged from 30.0 to 72.7 Gy (median 46.8 Gy). RT dose to the pelvis ranged from 30.0 to 45.0 Gy. Chemotherapy consisted of concurrent infusional 5-FU and IV bolus Mitomycin-C. Patient outcome was analyzed with respect to tumor stage and radiation dose. Follow-up time ranged from 7 to 193 months (median 40 months). Actuarial local tumor control (LC), disease-specific survival (DSS) and colostomy + disease-free survival (CDFS) rates were calculated. Sphincter function was assessed among 17 of 20 evaluable patients (alive without colostomy with a minimum follow-up time of 1 year) using the FAIT-F (Version 3) quality of life assessment tool in conjunction with standard continence criteria. RESULTS: Thirty-two patients had Stage I or II disease and 15 had Stage III disease. Twenty-two patients received ≤ 45 Gy of RT and 25 patients received > 45 Gy. Only (3(22)) (14%) of patients receiving ≤ 45 Gy had Stage III disease, compared with(12(25)) (48%) of patients receiving > 45 Gy. The actuarial 5-year patient outcome analysis is summarized below: Overall, (3(47)) (6%) patients required a colostomy following treatment. In 2 patients, salvage abdominal perineal resection (APR) was performed at the time of local failure, and 1 patient who received 65 Gy of RT required a diverting colostomy due to a non-healing anal ulcer following treatment

    The magnetic sphincter augmentation device continues to become a more common antireflux surgical option with low complication rates. Erosion into the esophagus is an important complication to recognize and is reported to occur at very low incidences (0.1-0.15%). Characterization of this complication remains limited. We aim to describe the worldwide experience with erosion of the magnetic sphincter augmentation device including presentation, techniques for removal, and possible risk factors. We reviewed data obtained from the device manufacturer Torax Medical, Inc., as well as the Manufacturer and User Facility Device Experience (MAUDE) database. The study period was from February 2007 through July 2017 and included all devices placed worldwide. In total, 9453 devices were placed and there were 29 reported cases of erosions. The median time to presentation of an erosion was 26 months with most occurring between 1 and 4 years after placement. The risk of erosion was 0.3% at 4 years after device implantation. Most patients experienced new-onset dysphagia prompting evaluation. Devices were successfully removed in all patients most commonly via an endoscopic removal of the eroded portion followed by a delayed laparoscopic removal of the remaining beads. At a median follow-up of 58 days post-removal, there were no complications and 24 patients have returned to baseline. Four patients reported ongoing mild dysphagia. Erosion of the LINX device is an important but rare complication to recognize that has been safely managed via minimally invasive approaches without long-term consequences.

    We sought to investigate the impact of the duration of second stage of labor on risk of severe perineal lacerations (third and fourth degree). This population based cohort study was conducted in the Stockholm/Gotland region, Sweden, 2008-2014. Study population included 52 211 primiparous women undergoing vaginal delivery with cephalic presentation at term. Unconditional logistic regression analysis was used to calculate crude and adjusted odds ratios (OR), using 95% confidence intervals (CI). Main exposure was duration of second stage of labor, and main outcome was risks of severe perineal lacerations (third and fourth degree). Risk of severe perineal lacerations increased with duration of second stage of labor. Compared with a second stage of labor of 1 h or less, women with a second stage of more than 2 h had an increased risk (aOR 1.42; 95% CI 1.28-1.58). Compared with non-instrumental vaginal deliveries, the risk was elevated among instrumental vaginal deliveries (aOR 2.24; 95% CI 2.07-2.42). The risk of perineal laceration increased with duration of second stage of labor until less than 3 h in both instrumental and non-instrumental vaginal deliveries, but after 3 h, the ORs did not further increase. After adjustments for potential confounders, macrosomia (birth weight > 4 500 g) and occiput posterior fetal position were risk factors of severe perineal lacerations. The risk of severe perineal laceration increases with duration until the third hour of second stage of labor. Instrumental delivery is the most significant risk factor for severe lacerations, followed by duration of second stage of labor, fetal size and occiput posterior fetal position.

    Sphincter of Oddi manometry (SOM) is recognized as the standard diagnostic modality for sphincter of Oddi dysfunction (SOD). However, SOM is not commonly performed because of its technical difficulty and the high incidence of post-procedural pancreatitis. To diminish post-procedural pancreatitis, we tried to develop a new method of SOM. This study examined the feasibility of SOM with a guide-wire-type manometer, which is commonly used to measure the arterial pressure for coronary angiography, for the assessment of SO motility. A total of 35 procedures were performed in 8 patients with biliary type III SOD and 14 patients with other disease. We performed SOM using the guide-wire-type manometer on SOD cases and other cases [amplitude, duration, frequency and the area under the curve (AUC) of SO contractions]. The mean time required for the measurement was 7.5 ± 4.1 min. The amplitude, frequency and AUC of SO contractions were significantly larger in the SOD cases than in other diseases (147.2 vs. 92.8 mmHg, p = 0.042; 10 vs. 5/min, p = 0.007; 2,837 vs. 1,122 mmHg s, p = 0.003, respectively). In 6 patients who underwent endoscopic sphincterotomy (EST), the SO amplitude decreased dramatically after EST. In this study, mild pancreatitis was observed in only one patient. SOM using a guide-wire-type manometer is safe, reliable and easy to apply for the clinical assessment of SO motility. The guide-wire-type manometer may become a new method to measure SO function for the diagnosis of SOD.

    To evaluate the efficacy of two-step retrograde closed stenting for treating canalicular laceration. methods: Forty-eight consecutive canalicular laceration cases (48 eyes) were randomised and divided into two groups: a one-step group and a two-step group. In the two-step group (23 cases), the first step was performed in the outpatient department and included identifying the medial cut end of the canaliculus and probing under a slit-lamp microscope, followed by a retrograde canalicular stenting assisted by a memory titanium stylet. The second step was canalicular anastomosis, which was performed in the operating room. In the one-step group (25 cases), all of the surgical procedures were performed when preoperative preparations were simultaneously available. The time elapsed from the doctor visit to the treatment was 4.3 ± 2.4 h in the two-step group and 18.8 ± 6.3 h in the one-step group (Ptwo-step group, and 51.4 ± 24.2 min was needed in the one-step group (Ptwo-step group and 5.4 ± 2.2 in the one-step group (Ptwo-step group and nine cases (36%) in the one-step group required other assisted methods to locate the medial cut end (P=0.007). Twenty-one cases (91.3%) in the two-step group and 20 cases (80%) in the one-step group achieved patent lacrimal drainage systems during a 12-month follow-up (P=0.528). The two-step canalicular anastomosis method allows an early search for the medial cut end of the canaliculus and improves the chances of finding it; it is also a quicker, less invasive method for treating canalicular lacerations.

    Objective: The objective of this study was to compare 5/0 polypropylene suture with 5/0 chromic catgut in small clean pediatric facial laceration repair in terms of cosmetic outcome. Study Design: Randomized controlled trial.Place and Duration of Study: Combined Military Hospital, Rawalpindi from 26th May 2012 to 25th Nov 2012.Patients and Methods: A total of 300 patients of both gender under 12 years of age, with small clean facial lacerations were selected and divided in two equal groups using random number tables. All the patients underwent suturing in minor operating theater of trauma centre CMH Rawalpindi as day care cases, under local anesthesia and aseptic measures. In group 1, polypropylene 5/0 suture was used where as in group 2 chromic catgut 5/0 was used for suturing. Aseptic dressing was applied. All patients were reviewed on 5th day (for stitch removal in polypropylene group) and 3 months post-operatively to establish cosmetic outcome which was determined by scar visual analog score both by parents of the child and consultant surgeon. Results: The mean VAS (visual analog score) as observed by Consultant surgeon was 79.14 and 78.63 for polypropylene and chromic catgut groups respectively. The mean VAS observed by the parents of the child for respective groups was 76.67 and 76.03. The significance value was 0.961 for parental VAS and 0.988 for surgeons VAS depicting insignificant difference in both suture groups.Conclusion: There is no long-term difference in cosmetic outcomes of both the sutures in the repair of facial lacerations in the pediatric population. No difference in complication rate of wound was observed. In addition, the parents of the children in absorbable suture group expressed satisfaction over prevention of psychological trauma of stitch removal. (author)

    Full Text Available Extensor tendon injuries are widely believed to be straightforward problems that are relatively simple to manage. However, these injuries can be complex and demand a thorough understanding of anatomy to achieve the best functional outcomes. When lacerations occur in the forearm as in Zones VIII and IX injury, the repair of the extensor tendon and muscle, and posterior interosseous nerve (PIN is often challenging. A review of the literature shows little guidance and attention for these injuries. We present four patients with injuries to Zones VIII and IX as well as a review of surgical technique, postoperative rehabilitation, and pearls that may be of benefit to those managing these injuries.

    The objective of the study was to compare the prevalence of incontinence disorders in relation with spontaneous vaginal delivery or cesarean section. Two hundred women with spontaneous vaginal deliveries only were compared with 195 women with cesarean deliveries only 10 years after first delivery. When compared with cesarean section, vaginal delivery was associated with an increased frequency of stress urinary incontinence (P = .006) and an increased use of protective pads (P = .008) as well as an increased frequency of fecal urgency (P = .048) and gas incontinence (P = .01). At multivariate regression analysis, mode of delivery showed no significant association with incontinence symptoms other than an increased risk for flatus incontinence in women with a history of obstetric anal sphincter injury (odds ratio 3.1; 95% confidence interval, 1.5 to 8.9). Incontinence symptoms are more common following spontaneous vaginal delivery when compared with cesarean section 10 years after first delivery. However, cesarean section is not associated with a major reduction of anal and urinary incontinence.

  17. Coexistence of elastic fibers with hyaluronic acid in the human urethral sphincter complex: a histological study.

    Science.gov (United States)

    Hinata, Nobuyuki; Murakami, Gen; Abe, Shin-ichi; Shibata, Shunichi; Morizane, Shuichi; Honda, Masashi; Isoyama, Tadahiro; Sejima, Takehiro; Takenaka, Atsushi

    2013-10-01

    To promote the prevention and treatment of urethral sphincteric dysfunction, we examined the distribution of elastic fibers around the urethral sphincter complex and the histological localization of hyaluronic acid in relation to elastic fiber architecture. Using elastica-Masson staining as well as biotinated hyaluronic acid binding protein, we examined specimens of the urethral sphincter complex obtained from 14 elderly Japanese cadavers, including 10 men and 4 women. As a control, we also observed other striated muscles in male cadavers. Elastic fibers were densely distributed throughout the submucosal and smooth muscle layers along the entire length of the male urethra, including the prostatic urethra. The levator ani fascia and rhabdosphincter also contained abundant elastic fibers. An intramuscular elastic net was seen in the rhabdosphincter but not in other striated muscles. Strong staining for hyaluronic acid was evident in the submucosa and smooth muscle sphincter of the urethra but not in the levator ani fascia or rhabdosphincter, suggesting that elastic fibers and hyaluronic acid might interact at the former sites. Gender related differences in the distribution of elastic fibers and hyaluronic acid were noted with a much lower density of elastic fibers and hyaluronic acid staining in women than in men. Urethral sites where elastic fibers and hyaluronic acid coexist could be targeted for the prevention and treatment of urethral sphincteric insufficiency. These findings should improve our understanding of the human urethral sphincter complex. Copyright © 2013 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    Full Text Available Billy H Cordon,1 Nirmish Singla,1 Ajay K Singla2 1Department of Urology, University of Texas Southwestern Medical Center, Dallas, TX, 2Department of Urology, University of Toledo College of Medicine, Toledo, OH, USA Abstract: The artificial urinary sphincter (AUS, which has evolved over many years, has become a safe and reliable treatment for stress urinary incontinence and is currently the gold standard. After 4 decades of existence, there is substantial experience with the AUS. Today AUS is most commonly placed for postprostatectomy stress urinary incontinence. Only a small proportion of urologists routinely place AUS. In a survey in 2005, only 4% of urologists were considered high-volume AUS implanters, performing >20 per year. Globally, ~11,500 AUSs are placed annually. Over 400 articles have been published regarding the outcomes of AUS, with a wide variance in success rates ranging from 61% to 100%. Generally speaking, the AUS has good long-term outcomes, with social continence rates of ~79% and high patient satisfaction usually between 80% and 90%. Despite good outcomes, a substantial proportion of patients, generally ~25%, will require revision surgery, with the rate of revision increasing with time. Complications requiring revision include infection, urethral atrophy, erosion, and mechanical failure. Most infections are gram-positive skin flora. Urethral atrophy and erosion lie on a spectrum resulting from the same problem, constant urethral compression. However, these two complications are managed differently. Mechanical failure is usually a late complication occurring on average later than infection, atrophy, or erosions. Various techniques may be used during revisions, including cuff relocation, downsizing, transcorporal cuff placement, or tandem cuff placement. Patient satisfaction does not appear to be affected by the need for revision as long as continence is restored. Additionally, AUS following prior sling surgery has comparable

  19. [Foreign body retention after soft tissue laceration. A case of insufficient inspection and documentation].

    Science.gov (United States)

    Kempf, L; Braun, K F; Neu, J

    2014-02-01

    A 52-year-old man sustained a laceration to his left eyebrow after a fall in his bathroom. His plastic glasses shattered upon impact. The patient was referred to a local emergency department. After a quick exploration by the physician on call, the wound was closed by a nurse using the Steri-Strip Wound Closure system. No further exploration or imaging was performed. Four weeks after the incident the patient presented to a dermatologist with a "foreign body sensation" at the site of the laceration. Assuming a foreign body granuloma, he was referred to a maxillofacial surgeon who removed plastic debris (parts of the glasses worn by the patient). The wound subsequently healed without further complications.The patient filed a complaint for inadequate treatment in the emergency department. No detailed patient and accident history had been obtained, the wound exploration performed by the physician was superficial, and the wound closure was performed by a nurse. The expert opinion of the arbitration board ascertained a medical malpractice in terms of insufficient history, examination, and a lack of documentation. Specific questioning of the accident history would have led to the suspicion of possible foreign bodies, thus, leading to a more thorough exploration and likely further imaging. The arbitration board concluded that obtaining a detailed accident history and an accurate examination would have revealed the foreign bodies and/or led to further imaging. Complying with this, the patient could have been spared further harm and secondary surgery would have been unnecessary.

  20. Acute Isolated Flexor Tendon Laceration Associated With a Distal Radius Fracture.

    Science.gov (United States)

    Hill, J Ryan; Alluri, Ram K; Ghiassi, Alidad

    2017-05-01

    Subacute rupture of the flexor tendons secondary to distal radius fractures is well documented. Recently, accounts of flexor tendon rupture following open reduction internal fixation have been associated with volar plate fixation. However, discovery of an occult traumatic flexor tendon laceration during fixation of an acute distal radius fracture is not well described. This case indicates the importance of careful preoperative and intraoperative examination of the flexor tendons in the setting of comminuted distal radius fractures. A forty-seven-year-old male sustained a comminuted, dorsally displaced distal radius fracture. Initial and post-reduction examinations revealed no gross functional abnormalities. Upon operative fixation of the fracture, laceration of the flexor digitorum profundus (FDP) tendon to the index finger was incidentally noted at the level of the fracture site. Due to extensive dorsal comminution, shortening, and the presence of a lunate facet fragment, we performed volar fragment-specific and dorsal spanning bridge plate fixation. The proximal and distal ends of the FDP tendon were marked, but repair was deferred until implant removal. This allowed for proper informed consent and avoided potential compromise of the repair given the presence of a volar implant. Acute flexor tendon rupture secondary to closed distal radius fractures may go unnoticed if a high index of suspicion is not maintained. Delayed diagnosis of these ruptures convolutes the mechanism of injury and disrupts the recovery process. Hand surgeons should be vigilant in examining flexor tendon function during the preoperative evaluation, especially in the setting of acute high-energy injury.

  1. Endosonography and magnetic resonance imaging in the diagnosis of high anal fistulae – a comparison

    Directory of Open Access Journals (Sweden)

    Iwona Sudoł-Szopińska

    2014-06-01

    Full Text Available Anal fistula is a benign inflammatory disease with unclear etiology which develops in approximately 10 in 100 000 adult patients. Surgical treatment of fistulae is associated with a risk of damaging anal sphincters. This usually happens in treating high fistulae, branched fistulae, and anterior ones in females. In preoperative diagnosis of anal fistulae, endosonography and magnetic resonance imaging play a significant role in planning the surgical technique. The majority of fistulae are diagnosed in endosonography, but magnetic resonance is performed when the presence of high fistulae, particularly branched ones, and recurrent is suspected. The aim of this paper was to compare the roles of the two examinations in preoperative assessment of high anal fistulae. Material and methods: The results of endosonographic and magnetic resonance examinations performed in 2011–2012 in 14 patients (4 women and 10 men with high anal fistulae diagnosed intraoperatively were subject to a retrospective analysis. The patients were aged from 23 to 66 (mean 47. The endosonographic examinations were performed with the use of a BK Medical Pro Focus system with endorectal 3D transducers with the frequency of 16 MHz. The magnetic resonance scans were performed using a Siemens Avanto 1.5 T scanner with a surface coil in T1, T1FS, FLAIR, T2 sequences and in T1 following contrast medium administration. The sensitivity and specificity of endosonography and magnetic resonance imaging were analyzed. A surgical treatment served as a method for verification. The agreement of each method with the surgery and the agreement of endosonography and magnetic resonance imaging were compared in terms of the assessment of the fistula type, localization of its internal opening and branches. The agreement level was determined based on the percentage of consistent assessments and Cohen’s coefficient of agreement, κ. The integrity of the anal sphincters was assessed in each case

  2. Intersphincteric anal lipofilling with micro-fragmented fat tissue for the treatment of faecal incontinence: preliminary results of three patients.

    2015-07-01

    Faecal incontinence is a very debilitating problem. Many techniques have been proposed to treat this condition, with controversial results. Autologous transplant of fat tissue is an established procedure used for the repair of tissue damage, and recent studies revealed the potentiality of tissue regeneration by human adipose-derived stem cells. We treated this condition with the injection, in the intersphincteric anal groove, of lipoaspirate processed by an innovative technology (Lipogems). The aim of the study was to evaluate the efficacy of Lipogems injection for the treatment of faecal incontinence. In February 2014 we treated 3 patients with faecal incontinence. The surgical procedure required three phases: lipoaspiration, processing of lipoaspirate with the Lipogems system, and injection of the obtained product in the intersphincteric anal groove. An accurate proctological examination followed at 1 week, 1 month and 6 months after treatment. Each patient reported an improved Wexner incontinence score at 1 month after the procedure. We observed an increase of resting pressure (by at least 10 mm Hg) and thickness of the internal anal sphincter respectively at ano-rectal manometry and by ultrasound (US) evaluation at the sixth month of follow-up. Our preliminary results are encouraging, but multicentric studies with longer follow-up are needed to validate this novel technique for treatment of faecal incontinence.

  3. Sacral neuromodulation effects on periurethral sensation and urethral sphincter activity.

    To characterize the effect of sacral neuromodulation (SNM) on urethral neuromuscular function. Following IRB approval, women with refractory overactive bladder (OAB) underwent standardized urethral testing prior to and after Stage 1 SNM implantation. Periurethral sensation was measured using current perception thresholds (CPT). Striated urethral sphincter activity was quantified using concentric needle electromyography (CNE) and Multi-Motor Unit Action Potential (MUP) analysis software. Nonparametric analyses were used to characterize pre/post changes with intervention. Baseline CPT and CNE findings were compared between SNM responders and non-responders. Twenty-seven women were enrolled in this pilot study with a mean age of 61 ± 13 years. Twenty of 26 women (76.9%) responded to SNM and went to Stage 2 permanent implantation. Four (14.8%) withdrew after Stage 1 implantation; three of the four withdrawals had not had therapeutic responses to SNM. CPT and CNE parameters did not significantly differ from baseline 2 weeks after SNM. Pre-SNM urethral sensation was not significantly different between responders and non-responders. However, responders had larger amplitude, longer duration and more turns and phases at baseline approaching significance, reflecting more successful urethral reinnervation, than non-responders. SNM does not alter urethral neuromuscular function 2 weeks post Stage 1 implantation. Copyright © 2012 Wiley Periodicals, Inc.

  4. The vagal control of the feline pyloric sphincter.

    Science.gov (United States)

    Edin, R; Ahlman, H; Kewenter, J

    1979-10-01

    In acute experiments on cats in chloralose anesthesia the effects of efferent and afferent electrical stimulation of the cervical vagi on an applied constant flow of saline through the feline pylorus was studied. The motor activity of the stomach was recorded simultaneously with a volume recording technique. Efferent cervical vagal stimulation caused a decrease in the transpyloric flow and an increased gastric motor activity. In a few animals the decreased transsphincteric flow was preceded by a short period of increased flow. When the transpyloric flow was reduced by splanchnic nerve stimulation or a noradrenaline infusion, vagal nerve stimulation induced an increased flow through the pylorus indicating the presence of relaxatory fibres to the pylorus within the vagi. Electrical stimulation of the central end of the ipsilateral vagal nerve in the neck, with the contralateral vagal verve left intact, resulted in a decreased transpyloric flow and relaxation of the stomach. This response could be induced with or without intact splanchnic nerves, and disappeared when the intact contralateral vagus was cut. It is concluded that the vagi mediate both excitatory and inhibitory fibres to the pyloric sphincter in the cat. A vago-vagal excitatory reflex to the pylorus can be elicited by afferent vagal nerve stimulation together with a vago-vagal relaxatory response of the stomach.

  5. Leg raise increases pressure in lower and upper esophageal sphincter among patients with gastroesophageal reflux disease.

    2016-07-01

    The purpose of this study was to determine the relation between posturally increased intra-abdominal pressure and lower/upper esophageal sphincter pressure changes in patients with gastroesophageal reflux disease. We used high resolution manometry to measure pressure changes in lower and upper esophageal sphincter during bilateral leg rise. We also examined whether the rate of lower and upper esophageal sphincter pressure would increase during leg raise differentially in individuals with versus without normal resting pressure. Fifty eight patients with gastroesophageal reflux disease participated in the study. High resolution manometry was performed in relaxed supine position, then lower and upper esophageal sphincter pressure was measured. Finally, the subjects were instructed to keep their legs lifted while performing 90-degree flexion at the hips and knees and the pressure was measured again. Paired t-test and independent samples t-test were used. There was a significant increase in both lower (P leg raise compared to the initial resting position. Individuals with initially higher pressure in lower esophageal sphincter (>10 mmHg) exhibited a greater pressure increase during leg raise than those with initially lower pressure (pressure ≤10 mmHg; P = 0.002). Similarly individuals with higher resting upper esophageal sphincter pressure (>44 mmHg) showed a greater pressure increase during leg raise than those with lower resting pressure (≤44 mmHg; P leg activities on intraesophageal pressure in patients with gastroesophageal reflux disease, indicating by means of high resolution manometry that diaphragmatic postural and sphincter function are likely interrelated in this population.

    2015-01-01

    Full Text Available Background: On an average 30-50% of patients who undergo incision and drainage (I and D of anal abscess will develop recurrence or fistula formation. It is claimed that finding the internal orifice of anal abscess to distract the corresponding anal gland duct; will decline the rate of future anal fistula. Surgeons supporting I and D alone claim that finding the internal opening is hazardous. This study is conducted to assess short-term results of optional method to manage patients with anal abscess and fitula-in-ano at the same time. Materials and Methods: In this cross-sectional descriptive study 49 from 77 patients with anal abscess whose internal orifice was not identified by pressing on the abscess, diluted hydrogen peroxide (2% and methylene blue was injected into the abscess cavity and the anal canal was inspected to find out the internal opening. Once the opening was distinguished, an incision was given from the anal verge to the internal opening. Results: The internal orifice was identified in 44 out of 49 patients (90% who underwent this new technique. Up to 18 months during follow-up, only 2.5% of patients with primary fistulotomy developed fistula on the site of a previous abscess. Conclusion: Conventional method to seek the internal orifice of anal abscesses is successful in about one-third of cases. By applying this new technique, surgeons would properly find the internal opening in >90% of patients. Needless to say, safe identification of the anal gland orifice in anal abscess disease best helps surgeons to do primary fistulotomy and in turn it would significantly decrease the rate of recurrence in anal abscess and fistula formation.

    Objective: To investigate proton magnetic resonance spectroscopy ( 1 H-MRS) findings and value on dog's brain contusion and laceration. Methods: Models of focal brain contusion and laceration in 10 dogs were established through hitting on the right frontal-parietal lobe with a freely drop of 200g weight at 1.3 m height. Serial examinations (1 h, 24 h, 72 h, 5 day, 8 day and 14 day after trauma) were performed with conventional MRI and 1 H-MRS. NAA/Cr, Cho/Cr and NAA/Cho rates were analyzed with GE system 1.5 T scanner and relative software. After examination, all dogs were executed to death. Pathological study was performed at local brain contusion. Results: 1 h and 24 h-post trauma, NAA/Cr, Cho/Cr, NAA/Cho were significantly reduced (NAA/Cr 0.843±0.214, 0.862±0.204, contralateral ones 1.069±0.284, 1.048±0.232, t=-7.227, -6.718, Cho/Cr 1.181±0.224, 1.243±0.134, contralateral 1.415±0.305, 1.455±0.159, t=-4.332, -4.489, NAA/Cho 0.701±0.147, 0.536±0.136, contralateral 0.832±0.245, 0.613±0.165, t=-2.652, -2.665. P 0.05), Cho/Cr was significantly increased (1.457±0.168, 1.572±0.374, contralateral 1.334±0.174, 1.366±0.352, t=7.312, 3.201. P<0.05). Inflammatory and glial hyperplasia was more significant, granuloma were seen. Lipid and Lac peak were not seen at all stages. Conclusion: MRS could be a methods to monitor neuron injury and repair, and dynamically to detect the metabolic changes of brain contusion and laceration, reflecting injury severity and provide theory data for early treatment and predicting long-term outcome after trauma.

    To investigate the emergency treatment on facial laceration of dog bite wounds and identify whether immediate primary closure is feasible. Six hundred cases with facial laceration attacked by dog were divided into two groups randomly and evenly. After thorough debridement, the facial lacerations of group A were left open, while the lacerations of group B were undertaken immediate primary closure. Antibiotics use was administrated only after wound infected, not prophylactically given. The infection rate, infection time and healing time were analyzed. The infection rate of group A and B was 8.3% and 6.3% respectively (P>0.05); the infection time was 26.3 ± 11.6h and 24.9 ± 13.8h respectively (P>0.05), the healing time was 9.12 ± 1.30 d and 6.57 ± 0.49 d respectively (Pbite wounds should be primary closed immediately after formal and thoroughly debridement. And the primary closure would shorten the healing time of the dog bite wounds without increasing the rate and period of infection. There is no potentiality of increasing infection incidence and infection speed, compared immediate primary closure with the wounds left open. On the contrary, primary closure the wounds can promote its primary healing. Prophylactic antibiotics administration was not recommended. and the important facial organ or tissue injuries should be secondary reconditioned.

    Investigations of young workers, including limited surveys in supervised school settings, suggested their elevated injury risk. This study identified factors contributing to cuts-lacerations among adolescents in New Jersey secondary school career, technical, and vocational education programs. Of 1,772 injuries reported between December 1, 1998, and September 1, 2010, 777 (44%) were cuts-lacerations; analyses focused on 224 reports (n = 182 post-exclusions) submitted after fall 2005 in three career groups-Food, Hospitality & Tourism (FH&T) (n = 71), Manufacturing & Construction (M&C) (n = 84), and Automotive & Transportation (A&T) (n = 27). Most students were "struck by" tools or hard surfaces (n = 93, 51%); 63 cuts were from knives in FH&T. In M&C, most cuts-lacerations were caused by hand-held tools (n = 18) and being "struck against/by" or "caught between hard surfaces" (n = 19). Males reported more cuts-lacerations (n = 145), most commonly among 11th graders (n = 54) and ages 16 to 17 years (n = 79). Fingers (n = 117) were most often injured, usually by cutting tools (n = 83). Training, supervision, and appropriate equipment, and further assessments of "struck by" and "pinch point" hazards, are needed. Copyright 2012, SLACK Incorporated.

    Full Text Available Purpose: To evaluate the impact of incontinence etiology on artificial urinary sphincter (AUS device outcomes. Materials and Methods: We identified 925 patients who underwent primary AUS placement from 1983 to 2011. The etiology of incontinence was categorized as radical prostatectomy alone, radical prostatectomy with radiation, benign prostate resection, and those with cryotherapy as a salvage prostate cancer treatment. Hazard regression and competing risk analyses were used to determine the association of the etiology of incontinence with device outcomes. Results: The distribution of the 4 etiologies of incontinence included: 598 patients (64.6% treated with prostatectomy alone, 206 (22.2% with prostatectomy and pelvic radiation therapy, 104 (11.2% with benign prostate resection, and 17 (1.8% with prior cryotherapy. With a median follow-up of 4.9 years (interquartile range, 1.2–8.8 years, there was significant difference in the cumulative incidence of device infection/urethral erosion events between the four etiologies (p=0.003. On multivariable analysis, prior cryotherapy (reference prostatectomy alone; hazard ratio [HR], 3.44; p=0.01, older age (HR, 1.07; p=0.0009 and history of a transient ischemic attack (HR, 2.57; p=0.04 were associated with an increased risk of device infection or erosion. Notably, pelvic radiation therapy with prostatectomy was not associated with an increased risk of device infection or erosion (reference prostatectomy alone, p=0.30. Conclusions: Compared to prostatectomy alone, prior treatment with salvage cryotherapy for recurrent prostate cancer was associated with an increased risk of AUS infection/erosion, whereas radiation (in addition to prostatectomy was not.

    The artificial urinary sphincter (AUS), which has evolved over many years, has become a safe and reliable treatment for stress urinary incontinence and is currently the gold standard. After 4 decades of existence, there is substantial experience with the AUS. Today AUS is most commonly placed for postprostatectomy stress urinary incontinence. Only a small proportion of urologists routinely place AUS. In a survey in 2005, only 4% of urologists were considered high-volume AUS implanters, performing >20 per year. Globally, ~11,500 AUSs are placed annually. Over 400 articles have been published regarding the outcomes of AUS, with a wide variance in success rates ranging from 61% to 100%. Generally speaking, the AUS has good long-term outcomes, with social continence rates of ~79% and high patient satisfaction usually between 80% and 90%. Despite good outcomes, a substantial proportion of patients, generally ~25%, will require revision surgery, with the rate of revision increasing with time. Complications requiring revision include infection, urethral atrophy, erosion, and mechanical failure. Most infections are gram-positive skin flora. Urethral atrophy and erosion lie on a spectrum resulting from the same problem, constant urethral compression. However, these two complications are managed differently. Mechanical failure is usually a late complication occurring on average later than infection, atrophy, or erosions. Various techniques may be used during revisions, including cuff relocation, downsizing, transcorporal cuff placement, or tandem cuff placement. Patient satisfaction does not appear to be affected by the need for revision as long as continence is restored. Additionally, AUS following prior sling surgery has comparable outcomes to primary AUS placement. Several new inventions are on the horizon, although none have been approved for use in the US at this point.

    We explored the psychological impact of disfigurement resulting from facial lacerations in patients who presented at an accident and emergency department in the UK. Patients participated in relevant sections of the Derriford Appearance Scale and State Trait Anxiety Inventory at one week and six months after injury. In all patients self-consciousness and anxiety scores were higher than in the general population. The extent of the scar, the patient's living arrangements, and the cause of the injury were significantly related to self-consciousness and anxiety. General self-consciousness improved at six months but not social self-consciousness and anxiety. These injuries may have a considerable impact on the lives of the affected people.

    Full Text Available AIM: To evaluate the efficacy and safety of one-stitch anastomosis through the skin with bicanalicular silicone tube intubation in repairing of bicanalicular laceration.METHODS:The clinical data of 15 consecutive patients with both superior and inferior canalicular laceration in one eye who underwent surgical repair using one-stitch anastomosis through the skin and bicanalicular stent were retrospective studied. All the operations were performed under surgical microscope, 5-0 silk sutures were used and were with bicanalicular silicone tube (diameter was 8mm intubation, for one lacerated canaliculi one-stitch anastomosis through the skin. The stents were left in place for 3 months postoperatively and then removed. The follow-up period was 3 - 36 months (average 14 months.RESULTS:In 15 patients, 13 patients were cured entirely, 1 patient was meliorated, 1 patient with no effects. All patients had got good recovery of eyelid laceration with no traumatic deformity in eyelid and canthus. Complication was seen in one case, for not followed the doctor’s guidance to come back to hospital to had the suture removed on the 7th day after operation, when he came at the 15th day, the inferior canalicular wall and eyelid skin were corroded by the suture caused 2mm wound, and the inside silicone tube was exposed, a promptly repair with 10-0 nylon suture was done, the wound healed in a week. There were no early tube protrusions and punctal slits in the patients.CONCLUSION:One-stitch anastomosis through the skin with bicanalicular silicone tube intubation is a good method in repair of bicanalicular laceration in one eye, the cut ends can be anastomosed directly, and with excellent cosmetic results, it is acceptable for the patients. For there is no suture remained in the wound permanently, so there is no suture-related granuloma which may cause obstruction or stenosis of canaliculi. It is simple, economical, effective and safe.

    To demonstrate a cost-effective, quick, and easily reproducible three-dimensional sticky note model to enhance the understanding and conceptualization of the geometry and steps of the pharyngeal flap and sphincter pharyngoplasty. The method involves making specified incisions and rearrangements of readily available components, including disposable clear plastic cups, yellow and pink sticky notes, and white paper. Once assembly is complete, further incisions and remodeling are performed to simulate a pharyngeal flap or sphincter pharyngoplasty. The cost of the materials to make one model was $0.94. Average construction time was less than 10 min. This three-dimensional model is an efficient, interactive, and simple visual aid to teach surgical trainees the geometry and steps of the pharyngeal flap and sphincter pharyngoplasty.

    Full Text Available OBJECTIVES: To search for relationships between phasic (P and terminal (T DO with age, urodynamic findings and sphincter behavior during involuntary detrusor contraction in woman. MATERIALS AND METHODS: Urodynamic studies (triple lumen catheter 7F, seated position of 164 successive women referred for LUTS with diagnosis of DO were reviewed. Patients were stratified in 4 sub-groups: pre- (18-44y, peri- (45-54 y, post-menopause (55-74 y and oldest old (≥ 75 y. The urethral sensor was positioned at the level of the maximum urethral closure pressure for sphincter behavior analysis. A variation of at least 5 cmH2O in pressure (detrusor or urethra was chosen to assert DO or sphincter response. Sphincter response was classified as relaxation (re before or during DO, or steady (st. RESULTS: Occurrence of P and TDO was similar: 77 P and 87 T. The PDO group was significantly younger (p = 0.0003. TDO was more frequent in patients with a history of neurological disease. The percentage of PDO remained almost constant in age groups, while that of TDO increased with age from 6.7% to 23.2% (p = 0.0013. Uninhibited contraction occurred at a smaller bladder volume in the P group: 149 ± 95 vs. 221 ± 113 mL (p < 0.0001. Steady sphincter predominated in the TDO subgroup: 45.9% vs. 32.1% and increased significantly in each DO sub-group of ³ 75y. CONCLUSION: Steady sphincter during both P and TDO, and occurrence of TDO appear as specific of aging. The last result could be related to structural changes in the detrusor muscle with aging.

    Sphincteroplasty (SP) is used to treat faecal incontinence (FI) in patients with a sphincter defect. Although sacral nerve stimulation (SNS) is used in patients, its outcome in patients with a sphincter defect has not been definitively evaluated. We compared the results of SP and SNS for FI associated with a sphincter defect. Patients treated by SNS or SP for FI with an associated sphincter defect were retrospectively identified from an Institutional Review Board approved prospective database. Patients with ultrasound evidence of a sphincter defect were matched by age, gender and body mass index. The main outcome measure was change in the Cleveland Clinic Florida Faecal Incontinence Score (CCF-FIS). Twenty-six female patients with a sphincter defect were included in the study. The 13 patients in each group were similar for age, body mass index, initial CCF-FIS and the duration of follow-up. No differences were observed in parity (P = 1.00), the rate of concomitant urinary incontinence (P = 0.62) or early postoperative complications. Within-group analysis showed a significant reduction of the CCF-FIS among patients having SNS (15.9-8.4; P = 0.003) but not SP (16.9-12.9; P = 0.078). There was a trend towards a more significant improvement in CCF-FIS in the SNS than in the SP group (post-treatment CCF-FIS 8.4 vs 12.9, P = 0.06). Net improvement in CCF-FIS was not significantly different between the groups (P = 0.06). Significant improvement in CCF-FIS was observed in patients treated with SNS but not SP patients. A trend towards better results was seen with SNS. Colorectal Disease © 2016 The Association of Coloproctology of Great Britain and Ireland.

    Full Text Available OBJECTIVE: To describe the arrangement of the muscle fibers of the striated urethral sphincter and its relationship with the prostate during the fetal period in humans. MATERIALS AND METHODS: We analyzed 17 prostates from well preserved fresh human fetuses ranging in age from 10 to 31 weeks postconception (WPC. Transversal sections were obtained and stained with Gomori's trichrome and immunolabeled with anti alpha-actin antibody. RESULTS: We found that the urethral striated sphincter (rabdosphincter is located on the periphery of the smooth muscle and there was no merge between striated and smooth muscle fibers in any fetal period. In the prostate apex, the striated sphincter shows a circular arrangement and covers completely the urethra externally, whereas adjacent to verumontanum, it looks like a "horseshoe" and covers only the anterior and lateral surfaces of the urethra. Near the bladder neck, in fetuses younger than 20 WPC, we have found striated muscle fibers only at the anterior surface of the prostate, while in fetuses older than 20 WPC, the striated muscle covers the anterior and lateral surfaces of the prostate. CONCLUSIONS: The urethral sphincter muscle covers the anterior and lateral surfaces of the urethra in all fetuses older than 20 WPC, close to the bladder neck and at the distal prostate. In the region of the prostate apex, the urethral sphincter covers completely the urethra circularly. The knowledge of the normal anatomy of the urethral sphincter in fetuses could be important to understand its alterations in congenital anomalies involving the base of the bladder, the bladder neck and the proximal urethra.

    Case records were reviewed to determine the diagnostic efficacy of plain radiographs in the evaluation of inflatable artificial urethral sphincters. Of 84 patients with prostheses, 21 (25%) developed complications. Fluid leaks were found in 16 patients who presented with recurrent incontinence; plain radiographs demonstrated an interval decrease in balloon reservoir diameter. Kinked tubing, which was evident on plain films, caused acute urinary retention in three patients. However, plain radiographs failed to detect evidence of prosthesis erosion into the urethra in either of two patients with this complication. Although urethroscopy is needed to detect urethral erosion, plain radiographs are inexpensive and reliable in the initial evaluation of artifical sphincter malfunction

    Background and purpose: The aim of this study was to define the effects of voluntary anal contraction on prostate motion in an experimental setting. Materials and methods: Thirty-eight patients (median age, 76 years) with prostate cancer underwent thin-slice computed tomography (CT) in the vicinity of the prostate before and after active anal contraction. Three-dimensional displacement of the pelvis and prostate was measured. Results: Mean (±standard deviation, SD) overall displacement of the prostate due to anal contraction was 0.3 ± 1.4 mm to the right, 9.3 ± 7.8 mm to the anterior, and 5 ± 4 mm to the cranial direction. Mean displacement of the pelvis was 0.5 ± 1.8 mm to the right, 4.1 ± 7.1 mm to the anterior, and 1 ± 3 mm to the cranial direction. Mean displacement of the prostate relative to the pelvis was 0.1 ± 1.1 mm to the left, 5.2 ± 3.3 mm to the anterior, and 4 ± 4 mm to the cranial direction. Conclusions: Voluntary anal contraction within an experimental setting induces large prostate and bone motion, mainly in the anterior and cranial directions. The frequency and magnitude of actual anal contractions during radiotherapy for prostate cancer need to be determined.

    To assess clinical outcomes of patients treated with a high-dose rate brachytherapy boost for anal canal cancer (ACC). From August 2005 to February 2013, 28 patients presenting an ACC treated by split-course external beam radiotherapy (EBRT) and HDR brachytherapy with or without chemotherapy in a French regional cancer center in Nice were retrospectively analyzed. Median age was 60.6 years [34 – 83], 25 patients presented a squamous cell carcinoma and 3 an adenocarcinoma; 21 received chemotherapy. Median dose of EBRT was 45 Gy [43.2 – 52]. Median dose of HDR brachytherapy was 12 Gy [10 - 15] with a median duration of 2 days. Median overall treatment time was 63 days and median delay between EBRT and brachytherapy was 20 days. Two-year local relapse free, metastatic free, disease free and overall survivals were 83%, 81.9%, 71.8% and 87.7% respectively. Acute toxicities were frequent but not severe with mostly grade 1 toxicities: 37% of genito-urinary, 40.7% of gastro-intestinal and 3.7% of cutaneous toxicities. Late toxicities were mainly G1 (43.1%) and G2 (22%). Two-year colostomy-free survival was 75.1%, one patient had a definitive sphincter amputation. High-dose rate brachytherapy for anal canal carcinoma as boost represents a feasible technique compared to low or pulsed-dose rate brachytherapy. This technique remains an excellent approach to precisely boost the tumor in reducing the overall treatment time

    The purpose of this study was to report our experience in the management of severe primary postpartum hemorrhage due to genital tract laceration following operative vaginal delivery with forceps using pelvic transcatheter arterial embolization (TAE). Ten women (mean age, 31.9 years) with severe primary postpartum hemorrhage due to genital tract laceration after operative delivery with forceps were treated with TAE. TAE was indicated because of intractable bleeding that could not be controlled with uterotonic drugs, blood transfusion, attempted suturing and packing in all patients. Postdelivery perineal examination showed cervical or vaginal tears in all women and associated paravaginal hematoma in four. Angiography revealed extravasation of contrast material in six patients. TAE performed with gelatin sponge allowed to control the bleeding in all patients. Cervical and vaginal suturing was made possible and successfully achieved in the six women who had failed suturing attempts before TAE. Paravaginal hematoma was successfully evacuated in four patients in whom it was present after TAE. No complications related to TAE were noted. We conclude that in women with severe primary postpartum hemorrhage due to genital tract laceration after operative delivery with forceps, TAE is effective and safe for stopping the bleeding and helps genital tract suturing and evacuation of hematoma.

    Full Text Available Various surgical approaches may be employed for esophageal resection. Major airway injuries due to transhiatal esophagectomy include vertical tears in the membranous trachea. Tracheal injury is an uncommon but potentially fatal complication. This article describes the technique to repair the posterior membranous tracheal tear, extended just over the carina through a transcervical–transsternal approach, thereby avoiding a second thoracotomy. Six patients with posterior membranous tracheal injury underwent this procedure. The laceration ranged from 3 cm to 5 cm in length. Four patients had received neoadjuvant chemoradiation. The management of tracheal laceration added approximately 60 minutes to the total operation time. There was no mortality related to tracheal injury. Patients were followed up for 6 months after surgery, and both posterior tracheal wall and transverse tracheotomy remained intact without stenosis. The transcervical–transsternal approach decreases the need of thoracotomy and its complications in patients with tracheal laceration in any stage, even in cases of an extended tear down to the carina.

    Although minor facial injuries are relatively common, their psychological impact is an area neglected in the literature. For physiologically major injuries (such as facial cancers, burns and fractures), the face has been suggested to be a psychologically significant area of the body and disfigurement has been found to have numerous potential social consequences for patients. This paper reports the findings of an inquiry that explored the psychological impact of minor facial injuries and the influence of patient and scar characteristics in relation to self-consciousness and anxiety levels. Data were collected in 2001 in an accident and emergency unit from patients with a visible laceration over 1.5 cm that was treatable in an outpatient setting. The Derriford Appearance Scale (with general and social self-consciousness subscales) and the State-Trait Anxiety Inventory were administered to 63 patients 1 week later; data on 50 patients were also available 6 months after the injury. Larger scar size, living alone and aetiology of injury were significantly related to self-consciousness and anxiety levels, although gender, age, socio-economic group, location of scar, satisfaction with appearance and number of scars were not. General self-consciousness improved at 6 months but social self-consciousness and anxiety remained the same. Patient factors were not related to changes in general self-consciousness over time. Minor facial scars can have significant psychological impact for some people. Awareness training for health professionals, social skills training for affected patients and a patient information leaflet are recommended.

    To describe and evaluate full-thickness skin grafting of equine wounds. Case series. Adult horses (n=6). A full-thickness graft was harvested from the pectoral region with the horse anesthetized or standing and sedated after local anesthetic infiltration. Grafts were attached to the cutaneous margin of the wound with staples and/or sutures if the horse was anesthetized or if the recipient site was desensitized. Cyanoacrylate glue was used to attach the grafts to the cutaneous margin of the wound of 3 horses. Medical records were reviewed for history, physical examination findings, grafting technique, postoperative complications, and outcome. Three horses had full-thickness skin grafting to cover a fresh defect created by excision of a cutaneous neoplasm, and 3 horses had full-thickness skin grafting to cover a fresh or granulating laceration. Grafts were completely accepted in 5 horses. The superficial layers of all grafts sloughed, but the final cosmetic appearance of accepted grafts was good. Full-thickness skin grafting can be performed in standing sedated horses with good cosmesis, especially when the meshed graft is expanded minimally. Good acceptance of a full-thickness graft can be expected, regardless of whether the graft is applied to a fresh or granulating wound.

    To help students critique sex/gender norms, sexuality educators should address men's anal pleasure. Men's anal receptivity blurs accepted binaries like male/female, masculine/feminine, and straight/queer. By suppressing men's receptivity, the taboo against men's anal pleasure helps legitimize hegemonic sex/gender beliefs--and the sexism,…

    2008-01-01

    Background and purpose: The aim of this study was to prospectively assess the quality of life (QOL) of patients treated by concomitant chemo radiation for locally advanced anal canal carcinoma. Materials and methods: We report on a subgroup of 119 patients enrolled in a 306-patient therapeutic intensification prospective trial (ACCORD 03). This trial evaluated the impact on colostomy-free survival of induction chemotherapy and/or high dose radiotherapy (factorial design 2 * 2 treatment arms). QOL was assessed both before and 2 months after treatment using the EORTC QLQ-C30 questionnaire as well as a questionnaire relating to anal sphincter conservative treatment (AS-CT). Results: Compared to pre-treatment scores, patients reported significant improvement in their emotional function (+8.4 points p = 0.002), global health status (+5.9 points p = 0.0007), as well as a decrease in insomnia (-13.8 points p < 0.0001), constipation (-12.0 points p < 0.0001), appetite loss (-10.3 points p < 0.0001) and pain (-9.6 points p = 0.0002). The AS-CT degree of satisfaction with intestinal functions score was increased (+11.2 points p < 0.0001). Conclusion: This is the first prospective study comparing QOL of patients with advanced anal canal carcinoma, before and 2 months after conservative treatment. Two months after treatment, QOL was improved. Induction chemotherapy and/or high dose radiotherapy did not provide a negative impact on QOL

    Transient lower esophageal sphincter relaxation (tLESR) and decreased basal lower esophageal sphincter (LES) pressure are postulated mechanisms of gastroesophageal reflux (GER). There is conflicting evidence on the effect of carbonated drinks on lower esophageal sphincter function. This study was conducted to assess the effect of a carbonated beverage on tLESR and LES pressure. High resolution manometry tracings (16 channel water-perfused, Trace 1.2, Hebbard, Australia) were obtained in 18 healthy volunteers (6 men) for 30 min each at baseline, and after 200 mL of chilled potable water and 200 mL of chilled carbonated cola drink (Pepsi [Pepsico India Ltd]). The sequence of administration of the drinks was determined by random number method generated by a computer. The analysis of tracings was done using TRACE 1.2 software by a physician who was unaware of the sequence of administration of fluids. The mean (SD) age of the participant was 37.3 (12.9) years. The median (range) frequency of tLESr was higher after the carbonated beverage (10.5 [0-26]) as compared to baseline (0 [0-3], p = 0.005) as well as after water (1 [0-14], p = 0.010). The LES pressure decreased after ingestion of the carbonated beverage (18.5 [11-37] mmHg) compared to baseline (40.5 [25-66] mmHg, p = 0.0001) and after water (34 [15-67] mmHg, p = 0.003). Gastric pressure was not different in the three groups. Ingestion of a carbonated beverage increases tLESr and lowers LES pressure in healthy subjects.

    Purpose: To determine the efficacy and tolerance of a standardized protocol of chemotherapy and low-dose radiotherapy in the treatment of anal cancer in human immunodeficiency virus (HIV)-infected patients. Methods and Materials: Between 1987 and 1995, eight HIV-positive patients with squamous cell carcinoma of the anal canal, four of whom had acquired immunodeficiency syndrome (AIDS), received therapy at the Kaiser Permanente Medical Center. All patients were treated using a combined modality approach consisting of lowdose radiotherapy (30 Gy in 15 fractions delivered 5 days/week), and chemotherapy [1000 mg/m 2 of 5-fluorouracil (5-FU) delivered on days 1-4 and 29-32 as a continuous infusion over 96 h, and 10 mg/m 2 of mitomycin C delivered as a bolus injection on day 1]. Patients have been followed from 4 to 81 months (mean 41, median 38). Results: All eight patients completed the therapy with minor variations to the protocol, and all have attained a clinical complete response. Four patients are alive and free of disease, and four died as a result of complications of AIDS, but remained free of anal carcinoma. There were no mortalities from the protocol and the morbidity was acceptable. Only one patient each was noted to have Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer Grade 4 hematologic and gastrointestinal acute toxicity, and no Grade 4 skin toxicity was noted. Conclusion: This combined therapy is effective for HIV-infected patients and appears to be tolerable with acceptable toxicities. It is best applied to patients who are HIV positive, or who have AIDS without concurrent major opportunistic infections. This approach is reasonable and affords patients a reasonably good chance at sphincter preservation by avoiding abdominoperineal resection. The optimal therapy for HIV-positive patients with advanced AIDS remains less well defined

    We report the impact of urethral risk factors on erosion rates and device survival outcomes after transcorporeal artificial urinary sphincter placement. We performed a retrospective analysis of all transcorporeal artificial urinary sphincters placed at a single institution between January 2000 and May 2014. We assessed patient demographic, comorbid diseases and surgical characteristics for risk factors considered poor for device survival. Risk factors were compared to postoperative complications requiring explantation, including cuff erosion, infection and device revision. A total of 37 transcorporeal artificial urinary sphincters were placed in 35 men. Placement was performed as a primary procedure in 21 of 37 cases (56.8%) and as salvage in the remainder. In this transcorporeal population there were 7 explantations (18.9%) due to erosion in 4 cases, cuff downsizing in 2 and infection in 1. Median followup from implantation to last followup was 8.5 months (range 0.9 to 63). Median time from artificial urinary sphincter placement to explantation was 17.3 months (range 0.9 to 63) and time specifically to transcorporeal erosion was 7.4 months (range 0.9 to 26). On univariate analysis no parameters were associated with sphincter cuff erosion but a history of an inflatable penile prosthesis was associated with a higher device explantation rate (60% vs 12.5%, p=0.04). No associations were revealed on multivariate logistic analysis. All 4 cuff erosion cases demonstrated greater than 2 urethral risk factors, including prior radiation therapy in all. The probability of cuff erosion in patients with 2 or more urethral risk factors was 1.65 times the probability of erosion in those with 0 or 1 urethral risk factor (95% CI 1.3, 2.2). The proportion of patients free of erosion at 35 months was 100% in those with 0 or 1 urethral risk factor and 64% in those with 2 or more risk factors (log rank test p=0.00). Similarly the proportion of patients free of explantation at 35 months

    To report clinical and dosimetric outcomes of a consecutive series of patients with anal cancer treated with volumetric-modulated arc therapy (VMAT) concomitant to chemotherapy (CT). A cohort of 39 patients underwent VMAT employing a schedule consisting of 50.4 Gy/28 fractions to the gross tumour volume (GTV) and 42 Gy/28 fractions to the elective nodal volumes for patients with cT2N0 disease. Patients with cT3-T4/N0-N3 tumours were prescribed 54 Gy/30 fractions to the GTV and 50.4 Gy/30 fractions to the gross nodal volumes if sized ≤3 cm or 54 Gy/30 fractions if > 3 cm. Elective nodal regions were given 45 Gy/30 fractions. CT was administered concurrently following Nigro's regimen. The primary end point was acute toxicity. Secondary end points were colostomy-free survival (CFS), disease-free survival (DFS), cancer-specific survival (CSS) and overall survival (OS). Dosimetric data are also provided. Median follow-up was 21 months. Maximum acute toxicities were: dermatologic-G3: 18%; gastrointestinal-G3: 5%; genitourinary-G3: 2%; anaemia-G2: 7%; leukopenia-G3: 28%; G4: 8%; neutropenia-G3: 13%; G4: 18%; thrombocytopenia-G3: 11%; and G4: 2%. The actuarial 2-year CFS was 77.9% [95% confidence interval (CI): 54-90.4%]. Actuarial 2-year OS and CSS were 85.2% (95% CI: 60.1-95.1%), while DFS was 75.1% (95% CI: 52.4.7-88.1%). Our clinical results support the use of VMAT as a safe and effective intensity-modulated radiotherapy (IMRT) option in the combined modality treatment of anal cancer, with consistent dosimetry, mild toxicity and promising sphincter preservation and survival rates. IMRT is a standard of care for patients with anal cancer, and VMAT is a robust technical solution in this setting.

    The aim of this study was to systematically review the findings of publications addressing the epidemiology of anal human papillomavirus (HPV) infection, anal intraepithelial neoplasia, and anal cancer in women. We conducted a systematic review among publications published from Jan. 1, 1997, to Sept. 30, 2013, to limit to publications from the combined antiretroviral therapy era. Three searches were performed of the National Library of Medicine PubMed database using the following search terms: women and anal HPV, women anal intraepithelial neoplasia, and women and anal cancer. Publications were included in the review if they addressed any of the following outcomes: (1) prevalence, incidence, or clearance of anal HPV infection, (2) prevalence of anal cytological or histological neoplastic abnormalities, or (3) incidence or risk of anal cancer. Thirty-seven publications addressing anal HPV infection and anal cytology remained after applying selection criteria, and 23 anal cancer publications met the selection criteria. Among HIV-positive women, the prevalence of high-risk (HR)-HPV in the anus was 16-85%. Among HIV-negative women, the prevalence of anal HR-HPV infection ranged from 4% to 86%. The prevalence of anal HR-HPV in HIV-negative women with HPV-related pathology of the vulva, vagina, and cervix compared with women with no known HPV-related pathology, varied from 23% to 86% and from 5% to 22%, respectively. Histological anal high-grade squamous intraepithelial lesions (anal intraepithelial neoplasia 2 or greater) was found in 3-26% of the women living with HIV, 0-9% among women with lower genital tract pathology, and 0-3% for women who are HIV negative without known lower genital tract pathology. The incidence of anal cancer among HIV-infected women ranged from 3.9 to 30 per 100,000. Among women with a history of cervical cancer or cervical intraepithelial neoplasia 3, the incidence rates of anal cancer ranged from 0.8 to 63.8 per 100,000 person-years, and in

    The development of a Pulse Height Analizer is described. This equipment is essential to analize data coming from detectors producing information codified in pulse amplitudes. The system developed consist of a Signal Input Module connected to a Controller Module based on a 8085A microprocessor capable to memorize pulses up to 1 uS in 256 channels with a resolution better than 20 mV. A Communication Module with a serial interface is used for data transfer to a host computer using RS232c protocol. The Monitoring and Operation Module consist of a hexadecimal Keybord, a 6 digit 7-segment display and a XY analog output enabling real time visualization of data on a XY monitor. The hardware and the software designed for this low cost system were optimized to obtain a typical dead time of approximately 100 uS. As application, this device was used to adquire curves at the Small Angle X-ray Scattering Laboratory in this Department. The apparatus performance was tested by comparing its data with a Northern Pulse Height Analizer model NS633 output, with favorable results. (Author) [pt

  4. Anal intraepitelial neoplasia: a narrative review

    Full Text Available Anal intraepitelial neoplasia (AIN constitutes a major health problem in certain risk groups, such as patients with immunosuppression of varied origin, males who have sexual relations with other males, and females with a previous history of vaginal or cervical abnormalities in cytology. Its relationship with the human papillomavirus (HPV infection has been well documented; however, many of the factors involved in the progression and regression of the viral infection to dysplasia and anal carcinoma are unknown. AIN can be diagnosed through cytology of the anal canal or biopsy guided by high-resolution anoscopy. However, the need for these techniques in high-risk groups remains controversial. Treatment depends on the risk factors and given the high morbidity and high recurrence rates the utility of the different local treatments is still a subject of debate. Surgical biopsy is justified only in the case of progression suggesting lesions. The role of the vaccination in high-risk patients as primary prevention has been debated by different groups. However, there is no general consensus on its use or on the need for screening this population.

    We review our outcomes and experience of artificial urinary sphincter implantation for patients with refractory urinary incontinence from different causes. Between April 2002 and May 2017, a total of 32 patients (median age, 40.8 years) with urinary incontinence had undergone artificial urinary sphincter placement during urinary tract reconstruction. Eighteen patients (56.3%) were urethral injuries associated urinary incontinence, 9 (28.1%) had neurogenic urinary incontinence and 5 (15.6%) were post-prostatectomy incontinence. Necessary surgeries were conducted before artificial urinary sphincter placement as staged procedures, including urethral strictures incision, sphincterotomy, and augmentation cystoplasty. The mean follow-up time was 39 months. At the latest visit, 25 patients (78.1%) maintained the original artificial urinary sphincter. Four patients (12.5%) had artificial urinary sphincter revisions. Explantations were performed in three patients. Twenty-four patients were socially continent, leading to the overall success rate as 75%. The complication rate was 28.1%; including infections (n = 4), erosions (n = 4), and mechanical failure (n = 1). The impact of urinary incontinence on the quality of life measured by the visual analogue scale dropped from 7.0 ± 1.2 to 2.2 ± 1.5 (P urinary sphincter implantation in our center are unique, and the procedure is an effective treatment as a part of urinary tract reconstruction in complicated urinary incontinence cases with complex etiology.

    Sphincter gymnastics seem to be able to recruit central pattern generators--networks of neurons that generate motor patterns--through peripheral rhythmic stimuli and to activate them without supraspinal signals. This physical therapy method is thus suitable for treating spinal cord injured and spinal cord transected patients, for it can reach below the injured segment and feed signals into the central nervous system, thus activating vital organs. This article presents some observations and discusses a possible mechanism.

    Mammalian tachykinins are a family of neuropeptides which are potent modulators of smooth muscle function with a significant contractile effect on human smooth muscle preparations. Tachykinins act via three distinct G protein-coupled neurokinin (NK) receptors, NK1, NK2 and NK3, coded by the genes TACR1, TACR2 and TACR3 respectively. The purpose of this paper was to measure the mRNA and protein expression of these receptors and their isoforms in the clasp and sling fibers of the human lower esophageal sphincter complex and circular muscle from the adjacent distal esophagus and proximal stomach. We found differences in expression between the different receptors within these muscle types, but the rank order of the receptor expression did not differ between the different muscle types. The rank order of the mRNA expression was TACR2 (α isoform)>TACR2 (β isoform)>TACR1 (short isoform)>TACR1 (long isoform)>TACR3. The rank order of the protein expression was NK2>NK1>NK3. This is the first report of the measurement of the transcript and protein expression of the tachykinin receptors and their isoforms in the muscles of the human lower esophageal sphincter complex. The results provide evidence that the tachykinin receptors could contribute to the regulation of the human lower esophageal sphincter, particularly the TACR2 α isoform which encodes the functional isoform of the tachykinin NK2 receptor was the most highly expressed of the tachykinin receptors in the muscles associated with the lower esophageal sphincter.

    Flexor tendon lacerations are traditionally repaired by using non-absorbable monofilament sutures. Recent investigations have explored to improve the healing process by growth factor delivery from the sutures. However, it is difficult to conjugate growth factors to nylon or other synthetic sutures. This study explores the performance of a novel electrochemically aligned collagen suture in a flexor tendon repair model with and without platelet derived growth factor following complete tendon laceration in vivo. Collagen suture was fabricated via electrochemical alignment process. Heparin was covalently bound to electrochemically aligned collagen sutures (ELAS) to facilitate affinity bound delivery of platelet-derived growth factor-BB (PDGF-BB). Complete laceration of the flexor digitorum profundus in the third digit of the foot was performed in 36 skeletally mature White Leghorn chickens. The left foot was used as the positive control. Animals were randomly divided into three groups: control specimens treated with standard nylon suture (n=12), specimens repaired with heparinated ELAS suture without PDGF-BB (n=12) and specimens repaired with heparinated ELAS suture with affinity bound PDGF-BB (n=12). Specimens were harvested at either 4weeks or 12weeks following tendon repair. Differences between groups were evaluated by the degree of gross tendon excursion, failure load/stress, stiffness/modulus, absorbed energy at failure, elongation/strain at failure. Quantitative histological scoring was performed to assess cellularity and vascularity. Closed flexion angle measurements demonstrated no significant differences in tendon excursion between the study groups at 4 or 12weeks. Biomechanical testing showed that the group treated with PDGF-BB bound heparinated ELAS suture had significantly higher stiffness and failure load (pBB bound suture had significantly higher ultimate tensile strength and Young's modulus (pBB improved biomechanics and vascularity during tendon healing

    2015-09-01

    Intrinsic sphincter deficiency (ISD) is a common cause of stress urinary incontinence and is associated with more severe symptoms, often being associated with failed previous surgery. Due to the impaired sphincteric function, alternative surgical approaches are often required. The purpose of this review is to appraise the contemporary literature on the diagnosis and management of ISD. A PubMed search was performed to identify articles published between 1990 and 2014 using the following terms: ISD, stress urinary incontinence and type III stress urinary incontinence. Publications were screened for relevance, and full manuscripts were retrieved. Most studies base the diagnosis of ISD upon urodynamic appearances using recognized criteria (Valsalva leak point pressure <60 cm H2O or a maximum urethral closure pressure <20 cm H2O) in addition to clinical features. A range of non-surgical and surgical treatment options are available for the patient. Pubovaginal slings are more effective than retropubic colposuspensions with outcomes comparable to those reported with midurethral slings. The artificial urinary sphincter provides long-term cure rates; however, it is associated with specific morbidity including device erosion, mechanical failure and revision. The benefits of bulking agents, however, are not sustained beyond 1 year. There are few randomized controlled trials that compare accepted treatments specifically for patients with ISD. The lack of standardization in the definition and diagnostic criteria used limits inter-study comparisons. An assessment of urethral pressure profile when combined with the clinical features may help predict outcomes of surgical intervention.

    Full Text Available OBJECTIVE: To analyze the impact of low levels of testosterone induced by orchiectomy and the effect of alpha-tocopherol supplementation on oxidative stress in the urethral sphincter. MATERIALS AND METHODS: Forty male Wistar rats weighing 250-300g were divided into four groups with 10 each: Sham group; Orchiectomy group: bilateral orchiectomy; Orchiectomy-pre-Tocopherol group: bilateral orchiectomy preceded by alpha-tocopherol supplementation for four weeks; Orchiectomy-full-Tocopherol group: bilateral orchiectomy with alpha-tocopherol supplementation for four weeks preceding the procedure and for eight weeks afterwards. At the protocol end, animals were euthanized and had the sphincter analyzed stereologically focusing on collagen and muscle fibers percentage. Oxidative stress levels were determined using 8-epi-PGF2. RESULTS: The 8-epi-PGF2 levels were statistically higher (p < 0.0003 in the Orchiectomy group compared to others groups while Sham and Orchiectomy-full-Tocopherol groups presented statistically similar values (p = 0.52. Collagen volumetric densities were significantly lower in Sham and Orchiectomy-full-Tocopherol groups (p < 0.022. Sham group presented statistically greater muscle fiber percent. CONCLUSION: Castration caused oxidative stress in the urethral sphincter complex, with increased collagen deposition. Alpha-tocopherol had a protective effect and its supplementation for twelve weeks provided the greatest protection.

    To assess the merits of currently available treatment options in the management of patients with low rectal cancer, a review of the medical literature pertaining to the operative and non-operative management of low rectal cancer was performed, with particular emphasis on sphincter preservation, oncological outcome, functional outcome, morbidity, quality of life, and patient preference. Low anterior resection (AR) is technically feasible in an increasing proportion of patients with low rectal cancer. The cost of sphincter preservation is the risk of morbidity and poor functional outcome in a significant proportion of patients. Transanal and endoscopic surgery are attractive options in selected patients that can provide satisfactory oncological outcomes while avoiding the morbidity and functional sequelae of open total mesorectal excision. In complete responders to neo-adjuvant chemoradiotherapy, a non-operative approach may prove to be an option. Abdominoperineal excision (APE) imposes a permanent stoma and is associated with significant incidence of perineal morbidity but avoids the risk of poor functional outcome following AR. Quality of life following AR and APE is comparable. Given the choice, most patients will choose AR over APE, however patients following APE positively appraise this option. In striving toward sphincter preservation the challenge is not only to achieve the best possible oncological outcome, but also to ensure that patients with low rectal cancer have realistic and accurate expectations of their treatment choice so that the best possible overall outcome can be obtained by each individual.

    The evolution of the artificial urinary sphincter has affected the current surgical options for urinary incontinence. With its unique features, the artificial urinary sphincter (AUS) has been an attractive option for the treatment of urinary incontinence regardless of gender. The current paper discusses the indications, contraindications, types of devices, surgical approaches, outcomes, and complications of the AUS in the treatment of both male and female urinary incontinence. A PubMed review of the available literature was performed and articles reporting implantation of artificial urinary sphincters for urinary incontinence in both male and female patients were evaluated. There was a comparable satisfactory continence rate after the implantation of an AUS (59~97% in males vs. 60~92% in females). In comparison, there were some differences in the indications, contraindications, surgical approaches, outcomes, and complications of the AUS implanted for urinary incontinence in male and female patients. AUS implantation is a safe and effective surgical option for the treatment of urinary incontinence of various etiologies. Continuous evolution of the device has made it an attractive option for the treatment of both male and female urinary incontinence.

    The surgical management of anal fistulas is still a matter of discussion and no clear recommendations exist. The present study analyses the results of the ligation of the intersphincteric fistula tract (LIFT) technique in treating complex anal fistulas, in particular healing, fecal continence, and recurrence. Between October 2010 and February 2012, a total of 26 consecutive patients underwent LIFT. All patients had a primary complex anal fistula and preoperatively all underwent clinical examination, proctoscopy, transanal ultrasonography/magnetic resonance imaging, and were treated with the LIFT procedure. For the purpose of this study, fistulas were classified as complex if any of the following conditions were present: tract crossing more than 30% of the external sphincter, anterior fistula in a woman, recurrent fistula, or preexisting incontinence. Patient's postoperative complications, healing time, recurrence rate, and postoperative continence were recorded during follow-up. The minimum follow-up was 16 months. Five patients required delayed LIFT after previous seton. There were no surgical complications. Primary healing was achieved in 19 patients (73%). Seven patients (27%) had recurrence presenting between 4 and 8 weeks postoperatively and required further surgical treatment. Two of them (29%) had previous insertion of a seton. No patients reported any incontinence postoperatively and we did not observe postoperative continence worsening. In our experience, LIFT appears easy to perform, is safe with no surgical complication, has no risk of incontinence, and has a low recurrence rate. These results suggest that LIFT as a minimally invasive technique should be routinely considered for patients affected by complex anal fistula. © The Author(s) 2013.

    Anal squamous cell carcinoma is rare in the general population but certain populations, such as persons with HIV, are at increased risk. High-risk populations can be screened for anal cancer using strategies similar to those used for cervical cancer. However, little is known about the use of such screening practices across jurisdictions. Data were collected using an online survey. Health care professionals currently providing anal cancer screening services were invited to complete the survey via email and/or fax. Information was collected on populations screened, services and treatments offered, and personnel. Over 300 invitations were sent; 82 providers from 80 clinics around the world completed the survey. Fourteen clinics have each examined more than 1000 patients. Over a third of clinics do not restrict access to screening; in the rest, eligibility is most commonly based on HIV status and abnormal anal cytology results. Fifty-three percent of clinics require abnormal anal cytology prior to performing high-resolution anoscopy (HRA) in asymptomatic patients. Almost all clinics offer both anal cytology and HRA. Internal high-grade anal intraepithelial neoplasia (AIN) is most often treated with infrared coagulation (61%), whereas external high-grade AIN is most commonly treated with imiquimod (49%). Most procedures are performed by physicians, followed by nurse practitioners. Our study is the first description of global anal cancer screening practices. Our findings may be used to inform practice and health policy in jurisdictions considering anal cancer screening

    Purpose: To investigate the influence of therapeutic parameters on local control in T2-T3 anal carcinoma treated by chemo-radiotherapy or radiation therapy alone. Materials and Methods: From 1976 to 1993, 137 patients with anal carcinoma staged T2 (85) or T3 (52) completed curative sphincter-conservating treatment, 54 with radiotherapy alone and 83 with concomitant chemo-radiotherapy. Radiation therapy was delivered in two sequences with a median gap of 46 days. The two main techniques used for the first sequence were a direct perineal cobalt field ± a sacral arc field with a median dose of 30 Gy/10 fractions/19 days (27.7%) and two antero-posterior opposed pelvic fields (≥ 6 MV photons) with a median dose of 40 Gy/20 fractions/31 days (62%). Iridium-192 implant boost was used in 116 patients (median dose 20 Gy, Paris system) and external radiation boost in 21 patients (median dose 20 Gy/10 fractions/13 days). Generally the chemoradiotherapy patients received starting on day 1 an IV bolus of Mitomycin-C (0.4 mg/kg, maximum 20 mg) and a 5-day continuous infusion of 5-fluorourcil 600-800 mg/m 2 /day. For surviving patients median follow-up was 65 months. Univariate and multivariate analyses were carried out to determine therapeutic parameters affecting local control after adjustment for clinical factors. Results: The 5-year actuarial local control was 77%. Factors associated with a decrease of local control in univariate analysis included: age less than 66 years (67% vs 85%), male gender (65% vs 81%), tumor extension more than (1(3)) circumference of the anal canal (68% vs 90%), lymph node involvement (64% vs 81%), use of external irradiation for the boost (62% vs 79%), and overall treatment time more than 74 days (69% vs 85%). In a multivariate analysis none of the therapeutic parameters remained significant when adjusted for the four significant clinical factors. The only therapeutic factor which might have had an impact was overall treatment time (p = .09

    Postoperative pancreatic fistula represents the most important complication after distal pancreatectomy. The aim of this study was to evaluate the use of a preoperative endoscopic injection of botulinum toxin into the sphincter of Oddi to prevent postoperative pancreatic fistula (German Clinical Trials Register number: DRKS00007885). This was an investigator-initiated, prospective clinical phase I/II trial with an exploratory study design. We included patients who underwent preoperative endoscopic sphincter botulinum toxin injection (100 units of Botox). End points were the feasibility, safety, and postoperative outcomes, including postoperative pancreatic fistula within 30 days after distal pancreatectomy. Botulinum toxin patients were compared with a control collective of patients undergoing distal pancreatectomy without botulinum toxin injection by case-control matching in a 1:1 ratio. Between February 2015 and February 2016, 29 patients were included. All patients underwent successful sphincter of Oddi botulinum toxin injection within a median of 6 (range 0-10) days before operation. One patient had an asymptomatic, self-limiting (48 hours) increase in serum amylase and lipase after injection. Distal pancreatectomy was performed in 24/29 patients; 5 patients were not resectable. Of the patients receiving botulinum toxin, 7 (29%) had increased amylase levels in drainage fluid on postoperative day 3 (the International Study Group of Pancreatic Surgery definition of postoperative pancreatic fistula grade A) without symptoms or need for reintervention. Importantly, no clinically relevant fistulas (International Study Group of Pancreatic Surgery grades B/C) were observed in botulinum toxin patients compared to 33% postoperative pancreatic fistula grade B/C in case-control patients (P pancreatectomy. The results of the present trial suggest its efficacy in the prevention of clinically relevant postoperative pancreatic fistula and are validated currently in the

    Full Text Available Artificial urinary sphincter (AUS is the gold standard treatment for urinary incontinence owing to sphincter incompetence. We reviewed our experience in AUS implantation. From 1995 to 2009, 19 patients underwent 25 AUS implantations performed by a single surgeon. The cause of incontinence was sphincter incompetence, which was secondary to prostate surgery, neurogenic bladder, radiation, and post-traumatic urethral lesion. Twenty-three prostheses were placed in the bulbar urethra for male patients: 11 AUS cuffs were placed through the perineal approach and 12 through the penoscrotal approach. Two procedures were applied over the bladder neck for the female patients. Through a retrospective review of charts, continence and complications were analyzed. The mean follow-up time was 50.0 ± 42.9 months (range: 2–146 months. There were 16 successful surgeries (64%, and these patients were free from the need for a pad. In eight surgeries (32%, the devices were removed due to infection, while one implantation (4% was unsuccessful due to perforation into the bulbar urethra. There was a statistically significant difference (p = 0.024 in failure rates between patients who received radiotherapy (100% and other patients (22.7%. There was no statistically significant difference in dry and revision rates (p > 0.05 between the perineal and penoscrotal approach. Accordingly, over half of the patients with total incontinence benefitted from AUS implantation. In consideration of the high failure rate for patients receiving radiotherapy, caution should be exercised in the use of implantation. Secondary implantation has a satisfactory success rate in selected patients. The same success rate was noted for both perineal and penoscrotal approaches.

    Full Text Available Paragangliomas of the cauda equina are rare neuroepithelial tumors, usually manifesting clinically as sciatica. Here, we report a case of cauda equina paraganglioma with an unusual course in a 43-year-old man. His main complaints were erectile and sphincter dysfunction. The low back pain was initially ascribed to accidental injury. Magnetic resonance imaging revealed intradural tumor at the L2/L3 level. The patient underwent gross tumor resection, and the diagnosis of paraganglioma was based on neuropathologic examination. The symptoms completely resolved after tumor resection.

Clinical outcomes are reviewed and compared so that measures to reduce their occurrence and improve outcome can be proffered. Methods Records of all children between the ages of 1-18 yrs, who presented with penetrating eye injuries at the eye clinic of the University of Port Harcourt teaching Hospital, Rivers state, Nigeria between January 2002 and December 2009 were included. Information retrieved -patient’s Bio data, presenting symptoms, presenting visual acuity (VA, source of injury, surgical intervention and outcome using VA. All data analysed with EPI Info version 6 with the aid of a statistician. Results Folders of thirty-six children (36 eyes between the ages of 0–18 years diagnosed with corneal laceration over a period of 8 years out of 65 cases managed within that period available. Other folders reported as missing. Male female ratio 3:1, the mean age is 8.7 years (SD ± 3.67. Only one presented within 24 hours.

    The purpose of this study was to investigate a means of providing pain relief during repair of facial lacerations in children in the emergency room. This study was conducted in the emergency room of a tertiary care, university-affiliated hospital. Fifty percent nitrous oxide was administered by the surgeon who sutured the laceration. A nurse monitored the child throughout the procedure. At the end of the procedure, pain scores were evaluated by the surgeon and nurse using the FLACC (face, legs, activity, cry, and consolability) scale, a structured observational-behavioral scale for measurement of pain. Sixty patients between the ages of 1 and 16 years participated in the study. Of these, 15 were sutured using standard care (lidocaine infiltration), and 45 children received nitrous oxide in addition to lidocaine infiltration. Nitrous oxide was administered for an average of 11.9 +/- 5.1 minutes (range, 4 to 30 minutes). Forty-three children recovered to preprocedure activity in less than 1 minute. Two children recovered in less than 3 minutes. Average FLACC scores during infiltration and suturing were significantly lower in the nitrous oxide group compared with controls (infiltration, 1.9 of 10 versus 9.7 of 10; suturing, 2 of 10 versus 8.8 of 10). Forceful restraining was necessary in all the controls, whereas in the nitrous oxide group mild force was required in only 15 percent. Seventy percent of the children receiving nitrous oxide had no side effects. Vomiting and nausea were the most common (17 percent), transient side effects. No respiratory or cardiovascular side effects occurred. Nitrous oxide can be safely administered by plastic surgeons while suturing facial lacerations in the emergency room. The fast onset and rapid recovery characteristics of nitrous oxide provide a convenient environment for performing short surgical procedures. This safe method for provision of analgesia and anxiolysis may be appealing to plastic surgeons for ambulatory procedures (e

    Hajipour, L; Gulihar, A; Dias, J

    2010-08-01

    We carried out lacerations of 50%, followed by trimming, in ten turkey flexor tendons in vitro and measured the coefficient of friction at the tendon-pulley interface with loads of 200 g and 400 g and in 10 degrees , 30 degrees, 50 degrees and 70 degrees of flexion. Laceration increased the coefficient of friction from 0.12 for the intact tendon to 0.3 at both the test loads. Trimming the laceration reduced the coefficient of friction to 0.2. An exponential increase in the gliding resistance was found at 50 degrees and 70 degrees of flexion (p = 0.02 and p = 0.003, respectively) following trimming compared to that of the intact tendon. We concluded that trimming partially lacerated flexor tendons will reduce the gliding resistance at the tendon-pulley interface, but will lead to fragmentation and triggering of the tendon at higher degrees of flexion and loading. We recommend that higher degrees of flexion be avoided during early post-operative rehabilitation following trimming of a flexor tendon.

    Full Text Available Inclusion body myositis (IBM is a progressive degenerative skeletal muscle disease leading to weakening and atrophy of both proximal and distal muscles. Dysphagia is reported in up to 86% of IBM patients. Surgical cricopharyngeal myotomy may be effective for cricopharyngeal dysphagia and there is one published report that botulinum toxin A, injected into the cricopharyngeus muscle using a hypopharyngoscope under general anesthesia, relieved IBM-associated dysphagia. This report presents the first documentation of botulinum toxin A injection into the upper esophageal sphincter using a flexible esophagogastroduodenoscope under conscious sedation, to reduce upper esophageal sphincter pressure and successfully alleviate oropharyngeal dysphagia in two IBM patients.

    Educators of trainees in procedure-based specialties need focused assessment tools that are valid, objective, and assess technical skills in a realistic context. A framework for hybrid assessment using standardized patient scenarios and bench skills testing might facilitate evaluation of competency. Seven PGY-1 obstetrics and gynecology residents participated in a hybrid assessment that used observed structured clinical examination (OSCE) by a standardized patient who had sustained a vaginal laceration during vaginal delivery. The residents elicited a history and counseled the patient, and then completed a laceration repair on a pelvic model. The residents were rated on their performance in the scenario, which included issues of cultural competency, rapport-building, patient counseling. The technical skills were videotaped and rated using a modified global assessment form by 2 faculty members on a 3-point scale from "not done" to "partly done" to "well-done." Residents also completed a subjective assessment of the station. Mean technical performance of the residents on the technical skills was 55% "well-done," with a range of 20%-90%. The assessment identified 3 residents as below the mean, and 1 resident with areas of deficiency. Subjective assessment by the residents was that juggling the technical, cognitive, and affective components of the examination was challenging. Technical skills can be included in a case-based assessment using scenarios that address a range of cognitive and affective skills required of physicians. Results may help training programs assess individuals' abilities as well as identify program needs for curricular improvement.

    Affectation of the bladder after open prostatectomy is demonstrated. Decrease in bladder capacity and bladder compliance, detrusor hyper-or hypo-activity and voiding dysfunction are observed. We propose to investigate the effects of robotic surgery on bladder and sphincter function through the comparative study of preoperative and postoperative urodynamic values 3 months after prostatectomy. Prospective study of 32 consecutive patients undergoing robotic prostatectomy. They all underwent urodynamic study one month before the intervention and 3 months after the radical prostatectomy. Twenty five percent of patients undergoing robotic prostatectomy showed detrusor hyperactivity accompanied by a decrease in bladder compliance of 30.2 to 21.8 ml/cmH2O. Urethral profile showed diminished functional length of 67 to 44 mm and decreased maximum urethral pressure of 48.5 to 29.3 cmH2O. After robotic prostatectomy 21.8% of patients had detrusor hypoactivity, obstruction decreased between 28.1% to 12.5%. Decreased bladder compliance, detrusor hypo- or hyperactivity and obstruction improvement observed in the study of the flow pressure have been associated with sphincter involvement. It is part of the complex of lower urinary tract dysfunction that occurs after robotic prostatectomy. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

    The aim of the study was to report our 13-year experience of 14 children with gluteus maximus muscular transposition to treat post-trauma fecal incontinence and discuss our technical modifications to this surgical procedure. Fourteen children (median age: 9.9years) with complete fecal incontinence after traumas received this procedure from December 1998 to February 2011. The major modification of the surgery was that we transposed two thick muscular bundles about 2cm in diameter bilaterally. They surrounded the middle portion of rectum to act as sphincters. We used dynamic defecography and anorectal endosonography to observe the functions of the transposed muscles. Wexner scores, fecal incontinence quality of life questionnaire and self-rated health measurement scale scores had been used to evaluate their life quality. The median follow-up time was 6.3years. Twelve children reported prominently improved fecal controls with reduced stool frequency. Postoperative dynamic defecography and anorectal endosongraphy vividly demonstrated the satisfactory voluntary contractile and relaxed states of the reconstructed muscle. Wexner scores were significantly improved both 1year and 2years after the procedure (Pgluteus maximus transposition for reconstruction of sphincter efficiently improved fecal control and life quality for pediatric patients with traumatic fecal incontinence.

    Full Text Available ObjectiveTo observe the efficacy of duodenoscopic treatment of biliary ascariasis while preserving the function of the duodenal sphincter and to explore the feasibility of this technique as the preferred method for treatment of biliary ascariasis. MethodsA retrospective analysis was performed on the clinical data of 69 patients with biliary ascariasis who received duodenoscopic treatment while preserving the function of the duodenal sphincter in our department from 2007 to 2013. ResultsAll the 69 patients with biliary ascariasis not only preserved the function of the duodenal sphincter, but also had the biliary ascarids successfully removed. The patients were discharged 2-3 days later and then received conventional helminthic treatment. No patients developed complications such as acute pancreatitis, bleeding, and perforation. ConclusionDuodenoscopic treatment of biliary ascariasis while preserving the function of the duodenal sphincter is safe and effective and causes fewer surgical complications, so it should be considered as the preferred method for treatment of biliary ascariasis.

    Full Text Available  Introduction:Anal condylomata acuminata was a well-known disease in ancient times but in recent years there has been a rapidly increasing number of people who suffer from this disease. The main cause of this disease is infection of human papilloma virus (HPV which occurs through sexual contact.Currently there are three different ways to treat anal condylomata. Small changes of anal condylomata can be treated with local therapeutic agents, but the best results of treatment of extensive changes are obtained by surgical techniques.Material/Methods:The study group consisted of 30 patients with diagnosed extensive anal condylomata who underwent surgery in Mikolaj Pirogow High Specialized Hospital in Lodz. The survey was conducted from 2007 to 2011. Patients had been directed to the surgical ward by general surgeons and practitioners, proctologists and urologists. The diagnosis was made after proctological assessment in the knee-chest position.Results:All patients underwent surgery and had complete macroscopic electroexcision of anal condylomata. In the research group there was no mortality. Postoperative complications occurred in 4 (13.3�20patients – postoperative bleeding. Strong pain was present in 14 (46.7�20patients but only in the postoperative period. During postoperative follow-up there was no observed infection in the anal region or recurrence of disease. In the operated group there were no observed cosmetic deformations of the anus and/or the anal canal, narrow anal canal or functional fecal incontinence symptoms.Conclusions:Surgical treatment of anal condylomata is an effective and safe method for the patient. In our research there were no serious postoperative complications or recurrence of the disease during the follow-up period.

    Full Text Available The most important component of the upper esophageal sphincter (UES is the cricopharyngeal muscle. During the measurement of sphincter pressure the catheter passed through the sphincter affects the pressure value. In Chagas' disease and primary achalasia there is an esophageal myenteric plexus denervation which may affect UES pressure. We measured the UES pressure of 115 patients with Chagas' disease, 28 patients with primary achalasia and 40 healthy volunteers. We used a round manometric catheter with continuous perfusion and the rapid pull-through method, performed in triplicate during apnea. Pressures were measured in four directions, and the direction with the highest pressure (anterior/posterior and the average of the four directions were measured. The highest UES pressure in Chagas' disease patients without abnormalities upon radiologic esophageal examination (N = 63 was higher than in normal volunteers (142.8 ± 47.4 mmHg vs 113.0 ± 46.0 mmHg, mean ± SD, P<0.05. There was no difference in UES pressure between patients with primary achalasia and patients with Chagas' disease and similar esophageal involvement and normal volunteers (P>0.05. There was no difference between patients with or without esophageal dilation. In the group of subjects less than 50 years of age the UES pressure of primary achalasia (N = 21 was lower than that of Chagas' disease patients with normal radiologic esophageal examination (N = 41, measured at the site with the highest pressure (109.3 ± 31.5 mmHg vs 149.6 ± 45.3 mmHg, P<0.01 and as the average of the four directions (64.2 ± 17.1 mmHg vs 83.5 ± 28.6 mmHg, P<0.05. We conclude that there is no difference in UES pressure between patients with Chagas' disease, primary achalasia and normal volunteers, except for patients with minor involvement by Chagas' disease, for whom the UES pressure at the site with the highest pressure was higher than the pressure of normal volunteers and patients with primary

    Full Text Available Abstract Background Stem cell injection therapies have been proposed to overcome the limited efficacy and adverse reactions of bulking agents. However, most have significant limitations, including painful procurement, requirement for anesthesia, donor site infection and a frequently low cell yield. Recently, human amniotic fluid stem cells (hAFSCs have been proposed as an ideal cell therapy source. In this study, we investigated whether periurethral injection of hAFSCs can restore urethral sphincter competency in a mouse model. Methods Amniotic fluids were collected and harvested cells were analyzed for stem cell characteristics and in vitro myogenic differentiation potency. Mice underwent bilateral pudendal nerve transection to generate a stress urinary incontinence (SUI model and received either periurethral injection of hAFSCs, periurethral injection of Plasma-Lyte (control group, or underwent a sham (normal control group. For in vivo cell tracking, cells were labeled with silica-coated magnetic nanoparticles containing rhodamine B isothiocyanate (MNPs@SiO2 (RITC and were injected into the urethral sphincter region (n = 9. Signals were detected by optical imaging. Leak point pressure and closing pressure were recorded serially after injection. Tumorigenicity of hAFSCs was evaluated by implanting hAFSCs into the subcapsular space of the kidney, followed two weeks later by retrieval and histologic analysis. Results Flow activated cell sorting showed that hAFSCs expressed mesenchymal stem cell (MSC markers, but no hematopoietic stem cell markers. Induction of myogenic differentiation in the hAFSCs resulted in expression of PAX7 and MYOD at Day 3, and DYSTROPHIN at Day 7. The nanoparticle-labeled hAFSCs could be tracked in vivo with optical imaging for up to 10 days after injection. Four weeks after injection, the mean LPP and CP were significantly increased in the hAFSC-injected group compared with the control group. Nerve regeneration and

    To investigate patients' bowel symptom experiences and self-care strategies following sphincter-saving surgery for rectal cancer and the relationship between bowel symptom experiences and the self-care strategies used. Earlier diagnosis of rectal cancer allows for less invasive surgical treatments such as sphincter-saving procedures to be performed. Although a permanent stoma is generally not required, patients experience changes in bowel function following this surgery. However, limited research exists on patients' bowel symptom experiences and the self-care strategies used to manage symptoms following sphincter-saving surgery of rectal cancer. Quantitative descriptive correlational. A convenience sample of 143 patients aged 30 to over 70 years was used. Data were collected (April 2010-December 2010) using the Illness Perception Questionnaires, the Difficulties of Life Scale and a researcher developed Self-care Strategy Measure. The research was underpinned by the Symptom Management Theory. Relating to the four most effective self-care strategies used respondents reporting more bowel symptom were more likely to use the self-care strategy proximity/knowing the location of a toilet at all times. Females, respondents with high timeline cyclical scores and respondents with high physiological responses scores were more likely to use protective clothing. Respondents reporting more bowel symptom and with high social responses scores were more likely to use bowel medication. Females were more likely to wear incontinence pads. This research provides insights into the daily bowel symptom experiences of patients following sphincter-saving surgery for rectal cancer. It demonstrates the range of self-care strategies that individuals use to manage their bowel symptoms and the self-care-strategies that were most effective for them. Patients should be encouraged to report on-going bowel problems following sphincter-saving surgery for rectal cancer. Supportive care for patients

    Substantial controversy and conflicting data exist regarding the survival of the artificial urinary sphincter in patients with prior radiation therapy. We present data from a multi-institutional analysis examining the effect of prior radiation for prostate cancer on device survival. A database was compiled of patients with artificial urinary sphincter cuff erosion, which included demographic and comorbid patient characteristics, functional analyses and interventions. We identified 80 patients with iatrogenic or idiopathic artificial urinary sphincter erosion. Idiopathic erosion cases were further analyzed to determine factors influencing device survival with specific stratification for radiation therapy. A total of 56 patients were identified with idiopathic artificial urinary sphincter erosion. Of those men 33 (58.9%) had not undergone radiation treatment while 23 (41.1%) had a history of brachytherapy or external beam radiotherapy. In patients without radiation erosion-free median device survival was 3.15 years (95% CI 1.95-5.80), in contrast to the median device survival of only 1.00 year (95% CI 0.36-3.00) in irradiated patients. The erosion-free survival experience of patients with vs without radiation differed significantly (Wilcoxon-Breslow test for equality of survivor functions p = 0.03). Radiation therapy in patients with known idiopathic cuff erosion in this contemporary analysis correlated with significantly increased time to erosion. Mean time to idiopathic cuff erosion was accelerated by approximately 2 years in irradiated cases. To our knowledge these data represent the first demonstration of substantial outcome differences associated with radiation in patients with an artificial urinary sphincter who present specifically with cuff erosion.

    The incidence of anal cancer has increased over the last 25 years. No organized screening exists for the precursors of anal cancer (anal intraepithelial neoplasia and carcinoma in situ) and diagnosis is often delayed. Treatment for precursor lesions is of limited success, while cancer management is traumatic for the patient. Like cancers of the cervix, most cases of anal cancer are associated with infection with human papillomavirus (HPV). With increases in the incidence of anal cancer, and in light of the availability of prevention strategies such as screening and HPV vaccination, it is important, from a public health perspective, to assess the economic burden of anal cancer in France. We performed a retrospective analysis based on data extracted from a French hospital database - the Programme de médicalisation des systèmes d'information (PMSI) - to assess the number and management of patients hospitalized for anal cancer in 2006. Data on radiotherapy sessions performed in private hospitals were obtained from the Statistiques annuelles des établissements de santé (SAE) database. Costs of hospitalization, from the healthcare-payer perspective, were obtained from official diagnosis-related group tariffs for public and private hospitals. Ambulatory and indirect costs were estimated using information obtained from the literature. In 2006, 3,711 patients with anal cancer were treated in hospitals in France. Of these, the majority were women (69%). The annual cost of hospital treatment for anal cancer was estimated at € 20,326,868. The overall estimated cost (including hospitalization, outpatient and daily allowances costs) to the healthcare payer was € 38,249,981. This study, the first to investigate the economic burden of anal cancer in France, shows that the management costs of anal cancer are high and comparable to cervical cancer management costs (€ 44 million). Further research is required to determine the cost of management of precursor lesions, which

    A 65-year-old woman suffered from both chronic gastroesophageal reflux, which was complicated by columnar metaplasia (Barrett's epithelium), and profound hypothyroidism. An esophageal motility tracing showed absence of peristalsis in the lower esophagus and the lower esophageal sphincter (LES) could not be identified. Thyroid replacement therapy, in conjunction with antacid and cimetidine treatment, was associated not only with improvement in the gastroesophageal reflux symptoms, but also with a return of esophageal peristalsis and LES pressure to normal. To support our clinical observations, we rendered four cats hypothyroid with 131 I and documented a fall in LES pressure. We propose that abnormal smooth-muscle function of the esophagus may be another manifestation of the gastrointestinal motility disturbances which are associated with hypothyroidism

    Incontinence after prostatectomy for benign or malignant disease is a well-known and often a feared outcome. Although small degrees of incidental incontinence may go virtually unnoticed, larger degrees of incontinence can have a major impact on a man's quality of life.Conceptually, post-prostatectomy incontinence may be caused by sphincter malfunction or bladder dysfunction, or both. Most men with post-prostatectomy incontinence (60% to 100%) have stress urinary incontinence, which is involuntary urinary leakage on effort or exertion, or on sneezing or coughing. This may be due to intrinsic sphincter deficiency and may be treated with surgery for optimal management of incontinence. Detrusor dysfunction is more common after surgery for benign prostatic disease. To determine the effects of surgical treatment for urinary incontinence related to presumed sphincter deficiency after prostate surgery for:- men with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) - transurethral resection of prostate (TURP), photo vaporisation of the prostate, laser enucleation of the prostate or open prostatectomy - and- men with prostate cancer - radical prostatectomy (retropubic, perineal, laparoscopic, or robotic). We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, and handsearching of journals and conference proceedings (searched 31 March 2014); MEDLINE (January 1966 to April 2014); EMBASE (January 1988 to April 2014); and LILACS (January 1982 to April 2014). We handsearched the reference lists of relevant articles and conference proceedings. We contacted investigators to locate studies. Randomised or quasi-randomised trials that include surgical treatments of urinary incontinence after prostate surgery.

    The authors compared the clinical, radiographic, and manometric findings in ten patients with atypical achalasia showing complete but short-duration lower esophageal sphincter (LES) relaxation with findings in 39 patients with classic achalasia. Patients with atypical achalasia were younger, had dysphagia and weight loss of shorter duration, and had less esophageal dilation than patients with classic achalesia. LES pressure and esophagogastric junction caliber, however, were similar in the two groups. The majority of patients in both groups responded well to pneumatic dilation. They conclude that achalasia with apparent LES relaxation may represent an early form of this motor disorder and that the radiographic findings remain characteristic except for less dilation of the esophagus

    The failure rate for anti-incontinence surgery ranges from 5% to 80%. There is not actual consensus on the use of artificial urinary sphincter (AUS) as treatment for recurrent urinary incontinence in women. Several authors have shown that AUS can be useful, if the intrinsic sphincteric deficiency is checked. We present the first case in Spain, to our knowledge, of laparoscopic implantation of AUS as treatment for female recurrent urinary incontinence. Under general anaesthesia, patient was placed in supine decubitus with slight Trendelenburg, access to the vagina was verified. Through a transperitoneal pelvic laparoscopic approach, Retzius space was opened and then the laterovaginal spaces up to the endopelvic fascia. To facilitate the dissection of the bladder neck, we inserted a swab into the vagina, performing simultaneous traction and countertraction manoeuvres. As an access port for the AUS, we widened the incision of the lower trocar. We adjusted the periurethral cuff and then placed the reservoir and the pump in the laterovesical space and the labia majora of the vulva, respectively. Lastly, we connected the 3 AUS elements and peritoneum was closed to isolate AUS from the intestine. The surgical time was 92min, the estimated blood loss was <100cc(3) and the hospital stay was 48h. There were no intraoperative or postoperative complications. The AUS was activated at 6 weeks. At 24 months, patient managed the AUS adequately and total continence was achieved. Laparoscopic implantation of AUS is a feasible technique. Transvaginal traction and countertraction manoeuvres can prevent intraoperative lesions. Copyright © 2016 AEU.

    Full Text Available OBJECTIVE: The aim of the study was to develop a new durable animal model (using rabbits for anatomical-functional evaluation of urethral sphincter deficiency. MATERIALS AND METHODS: A total of 40 New Zealand male rabbits, weighting 2.500 kg to 3.100 kg, were evaluated to develop an incontinent animal model. Thirty-two animals underwent urethrolysis and 8 animals received sham operation. Before and at 2, 4, 8 and 12 weeks after urethrolysis or sham operation, it was performed cystometry and leak point pressure (LPP evaluation with different bladder distension volumes (10, 20, 30 mL. In each time point, 10 animals (8 from the study group and 2 from the sham group were sacrificed to harvest the bladder and urethra. The samples were evaluated by H&E and Masson's Trichrome to determine urethral morphology and collagen/smooth muscle density. RESULTS: Twelve weeks after urethrolysis, it was observed a significant decrease in LPP regardless the bladder volume (from 33.7 ± 6.6 to 12.8 ± 2.2 cmH2O. The histological analysis evidenced a decrease of 22% in smooth muscle density with a proportional increase in the collagen, vessels and elastin density (p < 0.01. CONCLUSIONS: Transabdominal urethrolysis develops urethral sphincter insufficiency in rabbits, with significant decrease in LPP associated with decrease of smooth muscle fibers and increase of collagen density. This animal model can be used to test autologous cell therapy for stress urinary incontinence treatment.

    The oppossum sphincter of Oddi (SO) exhibits peristaltic spike bursts with accompanying contraction waves that originate proximally in the sphincter of Oddi and propagate toward the duodenum. In this study we recorded myoelectrical activity of the opossum SO and upper gastrointestinal tract in six conscious animals using chronically implanted electrodes. Biopolar electrodes were implanted in the gastric antrum, duodenum, SO segment, jejunum, and ileum. During fasting the frequency of SO spike bursts, scored as number per minute, showed a cyclic pattern consisting of four phases (A to D). Phase A had a low spike burst frequency of ∼2/min that lasted ∼20 min. In phase B, the spike burst frequency increased progressively during a 40-45 min interval culminating in a short interval of phase C activity characterized by a maximal spike burst frequency of ∼5/min. During phase D, the spike bursts decreased over 15 min to merge with the low frequency of phase A and the cycle repeated. Cycle length of the interdigestive SO cycle, 87±11 SD min, was virtually identical with that of the interdigestive migrating myoelectric complex (MMC) of the upper gastrointestinal tract. The onset of phase C activity in the SO began 1-2 min before phase III of the MMC activity in the duodenum. Feeding abolished the cyclic pattern of spike burst activity in the SO as well as in the upper gastrointestinal tract. After feeding the SO spike bursts occurred at a frequency of 5-6/min for at least 3 h. We conclude that: (a) During fasting, the oppossum SO exhibits cyclic changes in its spike burst frequency; (b) Maximal spike burst frequency of the SO occurs virtually concurrent with passage of phase III MMC activity through the duodenum and; (c) Feeding abolishes the interdigestive cyclic spike burst pattern of the SO as well as that of the gastrointestinal tract.

    The temporary prosthetic sphincterotomy is a possible treatment for neurologic detrusor sphincter dyssynergia (DSD). The purpose of the study was to verify the feasibility and effectiveness of the urethral stent (US) Temporary ALLIUM BUS "BULBAR URETHRAL STENT". A prospective, non-comparative, single-center starting in 2015 was conducted. Were included patients over 18 years, with a neurologic DSD proved urodynamically for which medical treatment was not indicated or failed. The primary endpoint was the percentage of patients who had a voiding method considered as improved or much improved at 1 month and the feasibility of the procedure. From January to June 2015, 7 patients, (mean age 47.9 years [24-76 years]) were prospectively enrolled. One patient was lost to sight at one month and therefore excluded. The median follow-up was 8.1 months (1-10 months). All procedures were technically successful. At 1 month, there were 57% of grade 2 complications (Clavien-Dindo), 1 of 6 patients had a migration of the US. At one month, quality of life and the urologic situation was considered good in 3 patients, unchanged in 2 patients and decreased in 1 patient. The study was stopped after the inclusion of seven patients. At the date of the latest news, 5 of 6 patients had a migrated or an explanted US. The temporary urethral stent ALLIUM BUS does not seem to be a possible surgical alternative for the treatment of detrusor sphincter dyssynergia. 4. Copyright © 2016 Elsevier Masson SAS.

    1995-01-01

    Sphincteric anatomy and function are present at the caecocolonic junction in several mammals. In humans, radiologists and endoscopists have respectively reported a circumferential contraction and a prominent ileocaecal fold at the border area between the caecum and the ascending colon. Anatomical findings on necropsy material failed to confirm its presence. Microscopic studies on surgical specimens showed the existence of muscular and innervational patterns different from those of adjacent areas. The aim of this work was to confirm the existence of a specialised fold at the caecocolonic junction in humans and to ascertain its role by carrying out a study of functional anatomy. Pancolonoscopies were performed on 100 patients and ileocaecal fold behaviour was observed before and after mechanical stimulation. Isolated ileocaecocolonic regions, surgically obtained, were filled with a fixative solution to study their macro and microscopic morphology after stimulation. Endoscopically, the ileocaecal fold was semilunar or circular in shape and spontaneous or evoked spasms occurred in 52 patients. A prominent circular fold could be seen in surgical specimens after stimulation. The entire muscle coat deeply penetrated this fold, showing the features characteristic of the ileocaecal junction. In particular, the inner portion of the circular muscle showed a peculiar arrangement and was thicker than elsewhere. These results show that in humans the caecocolonic junction is provided with a sphincter morphology and function. Little is known about its physiological relevance in ileal flow accommodation and caecal filling and emptying but it should not be underestimated with regard to some colonic motility disorders.

    Full Text Available Abstract Introduction A pancreatic pseudocyst is a common sequela of severe acute pancreatitis. Commonly, it presents with abdominal pain and a mass in the epigastrium several weeks after the acute episode and can be managed conservatively, endoscopically or surgically. We report a patient with a pancreatic pseudocyst awaiting endoscopic therapy who developed a life-threatening complication following a rather innocuous trauma to the abdomen. Case presentation A 23-year-old Asian male student presented as an emergency with an acute abdomen a week after a minor trauma to his upper abdomen. The injury occurred when he was innocently punched in the abdomen by a friend. He experienced only moderate discomfort briefly at the time. His past medical history included coeliac disease and an admission four months previously with severe acute pancreatitis. He was hospitalized for 15 days; his pancreatitis was thought to be due to alcohol binge drinking on weekends. Ultrasound scanning showed no evidence of gallstone disease. Five days after the trauma, he became anorexic, lethargic and feverish and started vomiting bilious content. Seven days post-trauma, he presented to our emergency department with severe abdominal pain. An emergency laparotomy was performed where a transverse linear duodenal laceration was found at the junction of the first and second part of his duodenum, with generalized peritonitis. His stomach and duodenum were stretched over a large pancreatic pseudocyst posterior to his stomach. It was postulated that an incomplete duodenal injury (possibly a serosal tear occurred following the initial minor trauma, which was followed by local tissue necrosis at the injury site resulting in a delayed presentation of generalized peritonitis. Conclusion This is the first reported case of a traumatic duodenal laceration following minor blunt trauma in the presence of a large pancreatic pseudocyst. Minor blunt abdominal trauma in a normal healthy adult

    The aim of the study was to determine the incidences of anal cancer and high-grade anal intraepithelial neoplasia (AIN2/3) over time in Danish women and men. Describing the burden of anal cancer and AIN may be valuable in future evaluations of the human papillomavirus (HPV) vaccine. We included all...... in women. Between 1978-1982 and 2003-2008, the age-standardized incidence rate of anal cancer increased from 0.68 to 1.48 per 100 000 person-years in women and from 0.45 to 0.80 per 100 000 person-years in men. Although there is no systematic screening for AIN in Denmark, we nevertheless identified 608...

    The incidence of high-grade anal intraepithelial neoplasia (HGAIN) -with an aetiological based on high-risk types of human papillomavirus- is increasing in some high-risk groups. Screening for HGAIN includes routine anal cytology and, more recently, HPV genotyping. The main objective of this study was to determine the sensitivity and specificity of anal cytology and HPV genotyping for the detection of HGAIN. This is a study to determine the correlation of cytological and microbiological findings with anal biopsy findings in a cohort of patients at high risk of developing AIN referred to the department of sexually transmitted infections of the Hospital Costa del Sol, Spain, between January 2008 and December 2014. Of the 151 patients subjected to screening, a total of 92 patients, all of them with the result of three screening test (anal cytology, genotyping and biopsy) were included in the study. Just under two-thirds (62%) of them were HIV-positive. The sensitivity and specificity of anal cytology to detect HGAIN were 52.8 and 85.7%, respectively (k: 0.328), and 78 and 62.8% to detect two or more HPV oncogenic genotypes (k: 0.417). The detection of oncogenic HPV genotypes allowed the identification of 23 new cases of HGAIN that had been underdiagnosed with anal cytology, with 14 cases containing at least three high-risk genotypes. Anal cytology did not show enough sensitivity in HGAIN screening. HPV genotyping has shown to be a useful tool to detect HGAIN cases, although it could lead to an over-diagnosis as a solitary screening procedure.

    Byrne, Ann-Maria

    2009-01-01

    INTRODUCTION: Necrotising fasciits is a rapidly progressive disease characterised by extensive necrosis of the fascia, skin, and subcutaneous tissue, with relative sparing of the underlying muscle. CASE PRESENTATION: We present the case of a 24-year old Irish male student who sustained a laceration to his right shin from contact with a coral reef while swimming in the Phuket region, off the west coast of Thailand. The following day, he returned to Ireland and presented with an aggressive and destructive variant of group A beta-hemolytic streptococcal necrotising fasciitis originating at the site of the coral reef injury, and exacerbated by the long-haul flight. He was successfully treated with aggressive surgical debridement, vacuum-assisted dressings, split skin grafting and broad spectrum antibiotics. CONCLUSION: Necrotising fasciitis can progress rapidly to systemic toxicity and even death without expedient diagnosis and aggressive treatment. Long-haul flights induce significant fluid accumulation in the lower extremity. These physiological fluid shifts may have contributed to the severity of our patient\\'s necrotizing condition following his flight from Thailand.

    Large numbers of dead seals with characteristic spiral lesions have been washing ashore around the North Atlantic over the past two decades. Interactions with ship propellers and shark predation have been suggested as the likely causal mechanisms. However, new evidence points towards a more likely candidate: grey seal predation. An adult male grey seal was observed and recorded catching, killing and eating five weaned grey seal pups over a period of one week on the Isle of May, Scotland. A further 9 carcasses found in the same area exhibited similar injuries. Post mortem analysis of lesions indicated the wound characteristics were similar to each other and in 12 of the 14 carcasses analysed, were indistinguishable from carcasses previously attributed to propeller interaction. We therefore propose that most of the seal carcasses displaying spiral lacerations in the UK are caused by grey seal predation. Cases in other locations should be re-evaluated using the scoring system presented here to identify whether grey seal predation is a major cause of mortality in phocid seals.

    Full Text Available Background: chronic anal fissure is one of the most frequent proctological disorders in Western populations. Open lateral internal sphincterotomy is one of the therapeutic options accepted as the treatment of choice for chronic anal fissure, since it reduces the hypertonia of the internal anal sphincter (the main etiopathogenic mechanism of fissures, decreases anal pain, and allows the fissure to heal. Material and methods: we carried out a prospective study of 120 patients operated on for chronic anal fissure with open sphincterotomy under local anesthesia at our Proctology Outpatient Unit from 1998 to 2001. No preoperative studies, bowel preparation, or antibiotic prophylaxis were carried out. All patients were followed up after 1 week, 2 months, 6 months, and 1 year, and underwent an anal manometry before and after surgery. Results: early complications: 3 hematoma-ecchymosis of the wound (2.5%, 3 self-limited hemorrhage events (2.5%. No hemorrhoidal thrombosis, fistulas, or perianal abscesses occurred. Fissures recurred in nine patients (7.5% within one year. The initial rate of incontinence of 7.5% at two months dropped down to 5% at six months. The mean resting pressure (MRP in incontinent patients was lower than in continent patients (55±7 mmHg versus 80.7 ± 21 mmHg. The difference in mean squeeze pressure (MSP between incontinent patients and continent patients was not statistically significant. Conclusions: open sphincterotomy under local anesthesia has a long-term rate of healing and a morbidity rate similar to other techniques. It may therefore be considered an effective treatment for chronic anal fissure.Introducción: la fisura anal crónica sigue siendo uno de los problemas proctológicos más frecuentes e incapacitantes en la población occidental actual.

    After swallowing, the upper esophageal sphincter (UES) needs a certain amount of time to return from maximum pressure to the resting condition. Disturbances of sphincter function not only during the swallowing process but also in this phase of pressure restitution may lead to globus sensation or dysphagia. Since UES pressures do not decrease in a linear or asymptotic manner, it is difficult to determine the exact time when the resting pressure is reached, even when using high resolution manometry (HRM). To overcome this problem a Machine Learning model was established to objectively determine the UES restitution time (RT) and moreover to collect physiological data on sphincter function after swallowing. HRM-data of 15 healthy participants performing 10 swallows each were included. After manual annotation of the RT interval by two swallowing experts, data were transferred to the Machine Learning model, which applied a sequence labeling modeling approach based on logistic regression to learn and objectivize the characteristics of all swallows. Individually computed RT values were then compared with the annotated values. Estimates of the RT were generated by the Machine Learning model for all 150 swallows. When annotated by swallowing experts mean RT of 11.16s±5.7 (SD) and 10.04s±5.74 were determined respectively, compared to model-generated values from 8.91s±3.71 to 10.87s±4.68 depending on model selection. The correlation score for the annotated RT of both examiners was 0.76 and 0.63 to 0.68 for comparison of model predicted values. Restitution time represents an important physiologic swallowing parameter not previously considered in HRM-studies of the UES, especially since disturbances of UES restitution may increase the risk of aspiration. The data presented here show that it takes approximately 9 to 11s for the UES to come to rest after swallowing. Based on maximal RT values, we demonstrate that an interval of 25-30s in between swallows is necessary until the

    In cancers of the distal rectum, preoperative radiotherapy is often associated with low anterior resection. This study assesses the choice of surgical procedure, oncological results, and quality of life outcomes in a retrospective cohort of patients with low-lying rectal cancers. The results obtained reinforce the notion of the feasibility, in routine practice, of sphincter-sparing surgery after preoperative radiotherapy in a significant proportion of low rectal cancers. The oncological results seem to be unaffected by the choice of surgical procedure. However, with the possible exception of body image and sexual aspects in males, quality of life parameters were not necessarily better in the restorative surgery group. Prospective studies are mandatory to clarify the putative quality of life advantages of sphincter-conserving procedures in this context. (author)

    Up to 50% of patients receiving an artificial urinary sphincter (AUS) require surgical revision after initial placement. However, the literature is heterogeneous regarding the leading causes of AUS failure and appropriate surgical management. To inform a revision approach by tabulating the causes of AUS failure, assessing AUS component survival, and examining the single-component revision efficacy. We retrospectively reviewed 168 patients receiving AUS placements carried out by a single surgeon from 2008 to 2016 at a high-volume academic institution. The median follow-up from initial placement was 2.7 yr, with 37.5% experiencing recurrent incontinence. The cuff size ranged from 4.0 to 5.5cm, with median size of 4.5cm. Patients without infection or erosion underwent systematic device interrogation and revision, starting with the pressure-regulating balloon (PRB) and then, if necessary, the urethral cuff. Device revision involved either PRB-only correction or cuff and PRB revision. We used bootstrapped intervals to estimate the mean time to failure for individual AUS components. Kaplan-Meier estimates were used to compare survival for individual components and for revised devices by revision technique. PRB malfunction most commonly caused device failure, while cuff or pump malfunction was rare. Among patients undergoing surgical revision, those with PRB-only correction had similar outcomes to those with more extensive device correction (cuff and PRB exchange; p=0.46). This study, while systematic and detailed, is limited by sample size, follow-up length, and its retrospective nature. PRB malfunction most commonly caused AUS failure in our cohort. PRB-only correction may satisfactorily restore AUS function in select patients. Consequently, initial interrogation of the PRB may avoid a second incision and urethral exposure for many patients requiring AUS revision. Artificial urinary sphincters remain prone to failure over time. In many instances, correcting only the

    Full Text Available Background: Whether preserving sphincter of Oddi (SO function by endoscopic papillary balloon dilation (EPBD is beneficial for preventing recurrent common bile duct stone disease (CBDS is controversial. The aim of this study was to measure sphincter of Oddi (SO function by using SO manometry, and to evaluate the association with recurrent CBDS. Methods: Patients with suspected CBDS who underwent successful EPBD were included. These patients underwent SO manometry at two months after EPBD with bile duct clearance. They were regularly followed for recurrent CBDS. Results: From January 2000 to December 2009, 185 patients received EPBD and SO manometry was included. There were 64% male with mean age of 65 ± 15.6 years. Mean ballooning inflation size was 1.1 ± 0.19 cm and mean ballooning time was 4.5 ± 0.85 min 55.7% had a sphincter of Oddi basal pressure (SOBP of 0 mmHg, 16.2%  40 mmHg. In multivariate analysis, EPBD with balloon ≥1.2 cm was the only factor for loss of SO function. Moreover, patients with preserved SO function had higher stone recurrence rate (15% vs. 5%, p = 0.034. Conclusion: EPBD using balloon ≥1.2 cm is a major factor for loss of SO function, which seems to reduce the risk of recurrent CBD stones.

    A 38-year-old white man had a 10-year history of human immunodeficiency virus (HIV) infection (A3), with no episodes of opportunistic diseases and in good immunologic recovery (CD4 cell count: 450 and indetectable HIV viral load) while on HAART. He presented with a two-month history of mild anal symptoms, including pruritus and episodic bleeding. He referred past episodes of anal warts, self-treated with several topical compounds, all proven unsuccessful. Perianal examination showed erythema and scratching. A 0.5cm sized tumor, with infiltration at the base was detected on digital exam, located at 15mm from the anal margin. Local biopsy driven by high-resolution anuscopy (AAR) yielded a final diagnosis of infiltrative epidermoid carcinoma. Might that neoplasia have been prevented? Copyright © 2013 Elsevier España, S.L.

    Full Text Available During the process of pregnancy, childbirth and puerperium the majority of the women experience a decrease of the frequency of the sexual relations, of the libido and of the pleasure that provides these relations to them. The presence of the episiotomy does that the normalization of the sexual relations is late. There does no seem to be relation between the type of childbirth (vaginal or caesarean and the sexual function. Certain factors influence the resumption of the sexual relations.Objectives: To determine the time that the women are late in the sexual relations restart after the childbirth vaginal route, to value that repercussion has the episiotomy and the perineal laceration on the regularization of the sexual activity of the women, to know that type of sexual relation is kept of beginning after the childbirth, to detect factors that influence the normalization of the sexual relations after the childbirth. Methodology: Observational, analytical prospective Study in the sanitary area of the Hospital San Juan de la Cruz de Úbeda, women who give birth in the Hospital San Juan de la Cruz de Úbeda (Jaen between the months of Julio and December, 2008, realizes telephonic interview to 60 days of the childbirth. There will be in use a questionnaire of proper elaboration. Discussion: Sex partner benefits physical, psychological and social, according to various studies, these relationships are affected by the process of pregnancy, childbirth and puerperium, a policy of selective episiotomy that recommends all the scientific evidence favors normalization of sexual activity. It is possible that we are certain biases such as non-response bias in classification, etc. but methodological tools to deal with its impact on the results are minimized.

    Esophageal axial shortening is caused by longitudinal muscle (LM) contraction, but circular muscle (CM) may also contribute to axial shortening because of its spiral morphology. The goal of our study was to show patterns of contraction of CM and LM layers during peristalsis and transient lower esophageal sphincter (LES) relaxation (TLESR). In rats, esophageal and LES morphology was assessed by histology and immunohistochemistry, and function with the use of piezo-electric crystals and manometry. Electrical stimulation of the vagus nerve was used to induce esophageal contractions. In 18 healthy subjects, manometry and high frequency intraluminal ultrasound imaging during swallow-induced esophageal contractions and TLESR were evaluated. CM and LM thicknesses were measured (40 swallows and 30 TLESRs) as markers of axial shortening, before and at peak contraction, as well as during TLESRs. Animal studies revealed muscular connections between the LM and CM layers of the LES but not in the esophagus. During vagal stimulated esophageal contraction there was relative movement between the LM and CM. Human studies show that LM-to-CM (LM/CM) thickness ratio at baseline was 1. At the peak of swallow-induced contraction LM/CM ratio decreased significantly (2). The pattern of contraction of CM and LM suggests sliding of the two muscles. Furthermore, the sliding patterns are in the opposite direction during peristalsis and TLESR. PMID:26045610

    2012-01-01

    This study aimed to apply novel high-resolution manometry with eight-sector radial pressure resolution (3D-HRM technology) to resolve the deglutitive pressure morphology at the esophagogastric junction (EGJ) before, during, and after bolus transit. A hybrid HRM assembly, including a 9-cm-long 3D-HRM array, was used to record EGJ pressure morphology in 15 normal subjects. Concurrent videofluoroscopy was used to relate bolus movement to pressure morphology and EGJ anatomy, aided by an endoclip marking the squamocolumnar junction (SCJ). The contractile deceleration point (CDP) marked the time at which luminal clearance slowed to 1.1 cm/s and the location (4 cm proximal to the elevated SCJ) at which peristalsis terminated. The phrenic ampulla spanned from the CDP to the SCJ. The subsequent radial and axial collapse of the ampulla coincided with the reconstitution of the effaced and elongated lower esophageal sphincter (LES). Following ampullary emptying, the stretched LES (maximum length 4.0 cm) progressively collapsed to its baseline length of 1.9 cm (P stomach. During ampullary emptying, the LES circular muscle contracts, and longitudinal muscle shortens while that of the adjacent esophagus reelongates. The likely LES elongation with the formation of the ampulla and shortening to its native length after ampullary emptying suggest that reduction in the resting tone of the longitudinal muscle within the LES segment is a previously unrecognized component of LES relaxation.

    Sphincter of Oddi dysfunction (SOD) refers to an abnormality of SO contractility. It is a benign, non-calculus obstruction to the flow of bile or pancreatic juice through the pancreaticobiliary junction. Although morphine can cause an excitatory effect on SO motility, there are no comprehensive data about opium as a risk factor in inducing SOD in chronic opium abusers. The aim of the study was to assess potential risk factors, especially opium addiction (OA), in patients with SOD. In a case-control study, opium addiction, cigarette smoking, cholecystectomy, and periampullary diverticulum in patients with SOD were recorded and compared with healthy subjects. SOD was diagnosed by the Geenen-Hogan classification (type I). OA (p=0.001) and cholecystectomy (p<0.001) were two independent risk factors in patients with SOD. Chronic use of opiates by the oral or inhalational route may induce SOD, but whether chronic use of other morphine derivatives or i.v. drug abuse induce this disorder is not clear and needs further evaluation.

    Esophageal dysphagia is a relatively common symptom. We aimed to evaluate whether subtle, presently not acknowledged forms of dysfunction of the lower esophageal sphincter (LES) could explain dysphagia in a subset of patients with normal findings at high-resolution manometry (HRM) according to the Chicago classification v3.0. We used HRM to compare LES relaxation characteristics in 97 patients with unexplained dysphagia with those in 44 healthy subjects. In addition, normative values for time to LES relaxation and completeness of LES relaxation were calculated. Patients with delayed or incomplete LES relaxation were compared with patients with normal relaxation. Dysphagia patients had a higher nadir LES pressure (P=.001) and a longer time to LES relaxation (P=.012) than healthy subjects. Based on the findings in healthy subjects, normal values of LES relaxation were defined as: ≥50% of swallows with normal LES relaxation time (relaxation (not reaching a value below 10 mm Hg). Dysphagia patients had significantly more often >50% swallows with delayed and/or incomplete LES relaxation than healthy controls (25% vs 4.5%; P=.004). Dysphagia patients with >50% delayed and/or incomplete LES relaxation had a significantly higher LES resting pressure (Prelaxation abnormalities, such as a delayed relaxation of the LES and/or incomplete LES relaxation, could be a cause of dysphagia in approximately one quarter of the patients with otherwise unexplained esophageal dysphagia. © 2017 John Wiley & Sons Ltd.

    Purpose: To evaluate the impact of preoperative external radiation therapy intensified by systemic chemotherapy including bolus cisplatin (c-DDP) and 4-day infusional 5-fluorouracil (PLAFUR-4) on tumor response and sphincter preservation in patients with extraperitoneal T3 rectal cancer with acceptable toxicity, and to compare the results to our previous experience with bolus mitomycin c (MMC) and 4-day infusion 5-FU (FUMIR). Methods and Materials: Between October 1995 and March 1998, 40 consecutive patients with resectable extraperitoneal adenocarcinoma of the rectum were treated with preoperative chemoradiation: slow infusion iv c-DDP, 60 mg/m 2 , day 1 and 29 plus 24-h continuous infusion iv 5-fluorouracil (5-FU) 1000 mg/m 2 , days 1-4 and 29-32, and concurrent external beam radiotherapy (45 Gy whole pelvis followed by 5.4 Gy boost). All but 3 patients had T3 disease. Surgery was performed 6-8 weeks after the end of chemoradiation. Results: No patient had Grade 4 acute toxicity. Grade 3 hematological toxicity was observed only in 2 (5%) patients. No patient had major gastrointestinal, skin, or urological acute toxicity. All patients had radical surgery. There was no perioperative mortality; perioperative morbidity rate was 12%. Overall, 23% (9 of 40) of patients had a complete pathological response and 10% (4 of 40) of patients had rare isolated residual cancer cells (Tmic). Comparing the stage at the diagnostic workup with the pathological stage, tumor downstaging was observed in 27 (68%) patients; nodal status downstaging was detected in 24 (60%) patients. Thirty-four (85%) patients had a sphincter-saving surgical procedure. In 4 of 10 (40%) patients who were definitive candidates for an abdominoperineal resection (APR), the sphincter was preserved, as it was in 13 of 13 (100%) probable candidates. Lengthening of the distance between the anorectal ring and the lower pole of the tumor ≥ 20 mm was observed in 9 (23%) patients. None of the patients had soilage

    No previous study has explored the relationship between cytology and the frequency of behaviours associated with anal sac disease (ASD). The goals of the study were: (i) to compare the cytological findings between anal sac secretions from normal dogs with no history of ASD to those with non-neoplastic ASD; (ii) to determine whether anal sac cytological findings can be used to differentiate between normal dogs and dogs with ASD; (iii) to explore the correlation of anal sac cytology and behaviour between normal dogs and dogs with ASD; and (iv) to describe behaviours typical of ASD as reported by owners. Thirty dogs were selected for this study, based on their behavioural history as detailed in a questionnaire completed by their owners. Of the thirty dogs, ten were considered normal insofar as they had no history of ASD clinical signs. The remaining 20 dogs were characterized as having ASD, with a chronic history of perianal pruritus, but no other pruritus. All dogs had their anal sacs manually expressed, and the discharge was examined microscopically in a blinded manner. A total of 171 oil immersion fields (OIFs) were examined from normal dogs and 333 OIFs from dogs with ASD. The behavioural results for dogs with ASD revealed that scooting recurred with a median frequency of 3 weeks post-anal sac expression. There were no clinically statistically significant cytological differences between normal dogs and those with ASD, thereby leading to the conclusion that cytology is an ineffective tool for diagnosing ASD. © 2010 The Authors.

    Full Text Available The purpose of the study was to compare immediate surgical outcomes of low anterior resections (LAR and intersphincteric resections (ISR of the rectum. Materials and methods. Treatment outcomes of 42 patients operated on between March, 2014 and January, 2015 were presented. Group I consisted of 24 patients who underwent laparoscopic ultra-low anterior resection (uLAR for rectal cancer. Group II comprised 18 patients who underwent laparoscopic ISR. Results. No significant differences in the median length of surgery and blood loss between two groups were observed. Circular and distal resection margins were negative in all cases. In 18 (75 % patients of Group I and in 14 (77.7 % patients of Group II, total mesorectumectomy(TME was assessed as grade 3 (p=0.83. The frequency of postoperative complications in uLAR-treated group was 20.8 %, not requiring a secondary revision procedure, and 27.8 % in ISR-treated group, requiring repeated surgery. The mean value of the fecal incontinence according to the Wechsler scale in a month after surgery was significantly higher in group II than in Group I patients (9.3 versus 6.2, р=0.01. The average treatment cost for uLAR was higher by 45,000 rubles than that for ISR. Conclusion. Both surgical procedures were matched by the duration of operation, amount of blood loss and the quality of mesorectumectomy. The complication rate was not significantly different between two groups, however, 16.8 % of Group II patients required relaparotomy, likely due to the mastering of the ISR technique. Ultra-low anterior resections of the rectum are functionally preferred. When performing ISR, the technique of reservoir colo-anal anastomosis with preservation of the portion of the internal sphincter provides functional results comparable with those obtained using LAR.

    Full Text Available Aim: To review 12 cases of anovestibular fistula with normal anal opening. Methods: Retrospective analysis of 12 children with anovestibular fistula and normal anal opening were treated between the years 2000 and 2007. Of these, 11 patients were diagnosed as having acquired anovestibular fistula with normal anal opening and were managed by conservative management. Results: Most of them presented with diarrhea and labial redness. One patient was considered to have fistula of congenital origin and was managed surgically. Eleven patients presented between the ages of 1.5-11 months and were considered as cases of acquired anovestibular fistula and only two of them required surgical management in the form of colostomy and fistula excision. Others were successfully managed by conservative treatment; the fistulous output and labial redness decreased gradually within a period of 5-19 (average 11.5 days. Conclusions: Not all presentations of anovestibular fistula with normal anal opening can be considered as congenital. Presence of inflammation, paramedian fistula, and a favourable response to conservative management/colostomy suggest acquired etiology. Trial of conservative management should be given in the acquired variety.

    From 1966 to 1981, 47 patients with a diagnosis of anal carcinoma were irradiated. This group was composed of 23 males and 24 females, with age ranging from 38 to 84 years (average 64.4 years). Five patients were treated preoperatively and 34 were treated definitively with cancericidal doses of irradiation. Acute radiation reactions requiring a rest-break were noted in 28% of patients, but all were managed as outpatients without untoward chronic sequelae. Chronic complications were noted in 13 patients, including two patients who required colostomy for severe anal stenosis and two who required A-P resection for large painful ulcers. Twenty-eight of 35 patients (80%) treated with irradiation alone have remained locally controlled without further treatment. An additional four have been salvaged by surgery. Only three patients had interstitial implants as part of their treatment course. Actuarial survival at five years for the N/sub 0/ patients and the group as a whole are 95.6 and 79.3%, respectively. It is concluded that external beam irradiation alone, properly fractionated to cancericidal doses, can control anal carcinoma with acceptable morbidity rates and without the use of either chemotherapy or interstitial implants in most cases. There is also a strong correlation suggesting that anal intercourse and male homosexuality play a significant role in the etiology of this disease.

    Patients with dysphagia may be diagnosed with impaired lower esophageal sphincter (LES) relaxation and treated with pneumatic dilation (PD), stretching and tearing LES muscle fibers. Esophageal perforation has been reported to be as high as 10%. We conducted a retrospective study to evaluate the perforation rate of PD when used for impaired relaxation of the LES using current techniques. A chart review was conducted to identify patients referred for esophageal manometry by high-resolution manometry and later received PD from January 2013 to April 2016. The diagnoses of achalasia, gastroesophageal junction outlet obstruction or hypertensive LES with accompanying impaired LES relaxation were based on the Chicago Classification III. Demographic data, clinical findings, treatment approaches and outcomes were explored. A total of 187 patients were referred for dysphagia and had esophageal manometry during this time frame. In all, 62 patients (34 female), mean age of 52 years, met the criteria for incomplete relaxation of the LES and underwent a total of 88 PD procedures. All initial PD procedures used the 30-mm diameter balloon, 18 subsequently required a 35-mm balloon and 8 went on to 40-mm balloon size. No perforations or other complications were documented by esophagogastroduodenoscopy, gastrografin testing immediately postdilation or by subsequent clinical outcome. PD by an experienced gastroenterologist using general anesthesia, fluoroscopic guidance, Rigiflex balloon equipment and a specific repetitive technique can be successfully performed without perforation. Hence, the already known therapeutic efficacy of PD can now be combined with the knowledge that there is essentially no accompanying perforation rate.

    Gilbert, R J; Dodds, W J

    1987-10-01

    We assessed the characteristics of muscarinic neural transmission in the vagal inhibitory pathway to the lower esophageal sphincter (LES) of anesthetized opossums. LES relaxation was induced by electrical stimulation of the cervical vagus. Measurements were made of LES relaxation before and after intravenous administration of nicotinic (hexamethonium), serotonergic (5-Meo-DMT), nonselective muscarinic (atropine), and selective muscarinic (pirenzepine-M1 and 4-DAMP-M2) antagonists. The latency of LES relaxation was increased substantially by pirenzepine and atropine, increased slightly by hexamethonium, but was not affected by 4-DAMP or 5-Meo-DMT. Given as concurrent intravenous infusions, hexamethonium, 5-Meo-DMT and 4-DAMP added to pirenzepine or atropine did not significantly increase LES relaxation latency above that caused by pirenzepine or atropine alone. None of the antagonists alone had a significant effect on percent LES relaxation. The combination of pirenzepine or 4-DAMP with hexamethonium and 5-Meo-DMT did not affect percent LES relaxation. The combination of atropine with hexamethonium and 5-Meo-DMT reduced LES relaxation to 18%. The combination of pirenzepine and 4-DAMP with hexamethonium and 5-Meo-DMT, however, had no effect on percent LES relaxation. We conclude that muscarinic participation in vagally induced LES relaxation exhibits two functional receptor subtypes: (1) M1 receptors that determine LES relaxation latency and are antagonized by pirenzepine or atropine, and (2) non-M1, non-M2 receptors (Mx receptors) that contribute to the magnitude of LES relaxation and are antagonized by atropine, but not by pirenzepine or 4-DAMP.

  15. Artificial urinary sphincter for urinary incontinence after radical prostatectomy: a historical cohort from 2004 to 2015

    Directory of Open Access Journals (Sweden)

    Augusto Cesar Soares dos Santos Junior

    Full Text Available ABSTRACT This study aimed to retrospectively evaluate a cohort of patients with prostate cancer and persistent urinary incontinence after radical prostatectomy. From January 2004 to December 2015, eighty-six individuals were identified to have received an AUS implant, provided by a private nonprofit HMO operating in Belo Horizonte, Brazil. On total, there were 91 AUS implants, with a median interval between radical prostatectomy and AUS implant of 3.6 years (IQR 1.9 to 5.5. The rate of AUS cumulative survival, after a median follow-up of 4.1 years (IQR 1.7-7.2 years, was 44% (n=40. The median survival of AUS implants was 2.9 years (IQR 0.5-7.9 years. Thirty-seven AUS implants (40.7% resulted in grade III surgical complications. There were 5 deaths at 2.1, 4.7, 5.7, 5.7 and 6.5 years of follow-up, but none due to causes directly associated to the AUS implant. Persistent severe incontinence was documented in 14 (15.3% additional patients. From the 51 AUS implants which resulted in grade III surgical complications or persistent severe incontinence, 24 (47.1% underwent surgical revisions. Explantation of the sphincter or its components was observed in 6 cases (25.0%. Mechanical failure, described as fluid loss and/or inability to recycle the AUS device, was observed in 4 devices (16.7%. In conclusion, although AUS implants are recommended as the gold-standard treatment of severe urinary incontinence after prostatectomy, the observed high rates of malfunction and grade III adverse events are a matter of concern warranting further assessment on the safety and efficacy of these devices.

    To characterize the risk of delayed infectious complications from retained pressure-regulating balloons (PRBs) after artificial urinary sphincter (AUS) cuff erosion. From our database of 530 AUS cases between 2007 and 2016, we identified 40 total AUS cuff erosions. Twenty-four (60%) presented without evidence of gross device infection and underwent explant of cuff and pump without removal of the PRB. Space of Retzius (SoR) and high submuscular (HSM) balloon locations were analyzed to assess for ease of removal. Presenting clinical features and retained balloon-related outcomes are reported. Of the 24 AUS cuff erosions with retained balloons, 6 (25%) men subsequently required PRB removal for infection during the median follow-up of 36 months (interquartile range 29-53). The median time to balloon infection after AUS erosion surgery was 4 months (interquartile range 4-16). Infection risk was reduced in those without concurrent inflatable penile prosthesis (20%) and in those who underwent "drain and retain" of the PRB (13%). The most common presenting clinical symptoms with retained PRB infection were pain and erythema near the site of the PRB (83%). No patient developed sepsis-related complications. The location of the PRB in this subcohort included 2 SoR and 4 HSM placements. The median operative time for balloon removal in the SoR was 3.5 times greater than that for HSM PRBs (133 minutes vs 38 minutes). With extended follow-up, three-quarters of the men with retained PRBs after AUS cuff erosion experienced no infectious complications. Removal of infected SoR PRBs was associated with greater operative times and surgical complexity relative to HSM PRBs. Copyright © 2017 Elsevier Inc. All rights reserved.

    Electrical stimulation therapy (EST) of lower esophageal sphincters (LES) is a new technique for the treatment of gastroesophageal reflux disease (GERD). In this paper, an implantable LES stimulator with wireless power transmission is proposed for the treatment of GERD. The LES stimulator is composed of an implantable pulse generator (IPG), an external controller, and a wireless power transmission module. The IPG, whose area is 31×21 mm 2 , is designed to generate voltage-regulated constant-current stimulation pulses. The external controller allows for wireless programming of the IPG via a Bluetooth Low Energy (BLE) module. The wireless power transmission module provides power for the IPG. According to the measurement of output stimulus waveforms, the proposed LES stimulator is capable of delivering electrical stimulations with a current ranging between 0 and 8 mA. To evaluate the safety and efficacy of the proposed LES stimulator, experiments were performed on 12 male New Zealand white rabbits. Esophageal manometry was performed before and after the procedure and the LES pressure (LESP) has been recorded. The mean LESP is increased significantly in the stimulation group than the sham group (stimulation group: 9.25±1.24 mmHg vs 13.99 ±1.28 mmHg, p<;0.05; sham group: 9.00±1.22 mmHg vs 9.23±1.27 mmHg, p=0.267). The results show that the electrical stimulation delivered by the LES stimulator can safely and effectively increase resting LES pressure in acute animal models, suggesting that the implantable LES stimulator is a perspective approach for treating GERD in clinics.

    At present, automated analysis of high-resolution manometry (HRM) provides details of upper esophageal sphincter (UES) relaxation parameters. The aim of this study was to assess the accuracy of automatic analysis of UES relaxation parameters. One hundred and fifty three subjects (78 males, mean age 68.6 years, range 26-97) underwent HRM. UES relaxation parameters were interpreted twice, once visually (V) by two experts and once automatically (AS) using the ManoView ESO analysis software. Agreement between the two analysis methods was assessed using Bland-Altman plots and Lin's concordance correlation coefficient (CCC). The agreement between V and AS analyses of basal UES pressure (CCC 0.996; 95% confidence interval (CI) 0.994-0.997) and residual UES pressure (CCC 0.918; 95% CI 0.895-0.936) was good to excellent. Agreement for time to UES relaxation nadir (CCC 0.208; 95% CI 0.068-0.339) and UES relaxation duration (CCC 0.286; 95% CI 0.148-0.413) between V and AS analyses was poor. There was moderate agreement for recovery time of UES relaxation (CCC 0.522; 95% CI 0.397-0.627) and peak pharyngeal pressure (CCC 0.695; 95% CI 0.605-0.767) between V and AS analysis. AS analysis was unreliable, especially regarding the time variables of UES relaxation. Due to the difference in the clinical interpretation of pharyngoesophageal dysfunction between V and AS analysis, the use of visual analysis is justified.

    To evaluate the influence of both repair type and degree of cuff erosion on postoperative urethral stricture rate. Sparse literature exists regarding patient outcomes after artificial urinary sphincter (AUS) cuff erosion. Surgeons from 6 high-volume male continence centers compiled a comprehensive database of post-erosion patients to examine outcomes. This retrospective multi-institution study included 80 patients treated for AUS cuff erosions. Seventy-eight patients had specific information regarding post-cuff erosion urethral strictures. Erosion patients were categorized into 1 of 3 repair types at the time of explant surgery: catheter only, single-layer capsule-to-capsule repair (urethrorrhaphy), and formal urethroplasty. Operative notes and available medical records were extensively reviewed to collect study data. Twenty-five of 78 patients manifested a urethral stricture after AUS cuff erosion (32%). More strictures occurred among patients who underwent urethrorrhaphy (40% vs 29% for catheter only and 14% for urethroplasty). Stricture rates did not vary significantly by repair type (P = .2). Strictures occurred significantly more frequently in patients with complete cuff erosions (58%) as compared to partial erosions (25%, P = .037). A trend was detected regarding increased percentage of erosion correlating with increased stricture rate, but this did not reach statistical significance (P = .057). Partially eroded patients were more likely to undergo urethrorrhaphy repair (60%, P = .002). Urethral stricture was more likely to occur after complete cuff erosion as opposed to partial erosion in this multicenter retrospective population. Repair type, whether catheter only, urethrorrhaphy, or formal urethroplasty, did not appear to influence postoperative stricture rate. Copyright © 2017 Elsevier Inc. All rights reserved.

    Stress urinary incontinence (SUI) is a degradation of the quality of life factor in the consequences of radical prostatectomy. Artificial urinary sphincter (AUS) is the standard treatment. Screening and preoperative treatment of anastomotic strictures (AS) is an essential step for the success of the intervention. The objective of the study was to assess the impact of AS on the results of AUA. We retrospectively studied 147 AUS settlements from 2005 to 2013 in the urology department of the Centre Hospitalier Lyon by three operators. The demographic characteristics, the irradiation history, the severity of incontinence, the complications of AUS, the continence rate and the postoperative satisfaction were collected. Wilcoxon statistical tests and Fischer and a Kaplan-Meier curve were used to compare the two control groups and AS. Logistic regression analysis looked for predictors of surgical reintervention. Of the 147 patients included, 24 (16.3%) had a history of AS. Of these, 21 (87.5%) were treated with endoscopic urethrotomy. Patients in the AS group had more severe incontinence (P<0.05) than in the control group. Explantation rates, recurrence of incontinence and reoperation was 12.5%, 8.3% and 33.3% in the AS group against 4.9%, 15.4% and 27.6% in the control group. In logistic regression, history of AS has not been found as reoperation risk factor. Continents and satisfied patients rate were 77.8% and 76.5%, respectively in the AS group against 91.1% and 81.1% in the control group. The history of AS does not appear to be predictive of poor outcome after implementation of a AUS. Larger cohort studies are needed to confirm these results. 4. Copyright © 2016 Elsevier Masson SAS.

    Full Text Available Anal cancer is relatively rare; however, its incidence has increased in recent years. Several risk factors are associated with the development of anal cancer, including age older than 50 years, low-fiber diet, chronic anal fistulas, smoking, multiple partners, anal intercourse practice, Human Immunodeficiency Virus infection and immunosuppression. However, the presence of human papillomavirus represents the main risk factor for the development of anal cancer. The aim of this study was to evaluate the clinicopathological aspects of a series of patients with anal carcinomas diagnosed in Hospital Araújo Jorge, Goiânia-Goiás, as well as the prevalence of human papillomavirus genome in these tumors. Clinical, pathological and socio-demographic data were collected from the respective medical files and paraffin blocks containing anal carcinomas specimens were used for DNA extraction and detection of human papillomavirus, by means of polymerase chain reaction, using short PCR fragment primers. Forty-three cases were selected and had the data analyzed, while 38 cases were tested for human papillomavirus genome detection. Among the evaluated patients, 62.8% were women; 53.4% of tumors were squamous cell carcinoma and 46.5% of the patients were aged between 60 and 75 years. Risk factors, such as smoking (39.5% and alcoholism (20.9% were recorded in the studied group. Lymph node metastases were detected in 30.2% of cases and 7.0% had distant metastasis. The detection of human papillomavirus DNA was positive in 76% of cases assessed and this was significantly associated with squamous cell carcinomas. Aggressive behavior and advanced stage of anal cancer described in this study highlight the need for preventive measures that contemplate these tumors, including vaccination against human papillomavirus.

    The rectum is insensitive to stimuli capable of causing pain and other sensations when applied to a somatic cutaneous surface. It is, however, sensitive to distension by an experimental balloon introduced through the anus, though it is not known whether it is the stretching or reflex contraction of the gut wall, or the distortion of the mesentery and adjacent structures which induces the sensation. No specific sensory receptors are seen on careful histological examination of the rectum in humans. However, myelinated and non-myelinated nerve fibres are seen adjacent to the rectal mucosa, but no intraepithelial fibres arise from these. The sensation of rectal distension travels with the parasympathetic system to S2, S3 and S4. The two main methods for quantifying rectal sensation are rectal balloon distension and mucosal electrosensitivity. The balloon is progressively distended until particular sensations are perceived by the patient. The volumes at which these sensations are perceived are recorded. Three sensory thresholds are usually defined: constant sensation of fullness, urge to defecate, and maximum tolerated volume. The modalities of anal sensation can be precisely defined. Touch, pain and temperature sensation exist in normal subjects. There is profuse innervation of the anal canal with a variety of specialized sensory nerve endings: Meissner's corpuscles which record touch sensation, Krause end-bulbs which respond to thermal stimuli, Golgi-Mazzoni bodies and pacinian corpuscles which respond to changes in tension and pressure, and genital corpuscles which respond to friction. In addition, there are large diameter free nerve endings within the epithelium. The nerve pathway for anal canal sensation is via the inferior haemorrhoidal branches of the pudendal nerve to the sacral roots of S2, S3 and S4. Anal sensation may be quantitatively measured in response to electrical stimulation. The technique involves the use of a specialized constant current generator

    Full Text Available Artificial urinary sphincters (AUSs are commonly used after radical prostatectomy for those who are incontinent of urine. However, they are associated with complications, the most common being reservoir uprising or migration. We present a unique case of occlusive external iliac and femoral vein obstruction by the AUS reservoir causing thrombosis. Deflation of the reservoir and anticoagulation has, thus far, not been successful at decreasing thrombus burden. We present this case as a rare, but significant surgical complication; explore the risk factors that may have contributed, and other potential endovascular therapies to address this previously unreported AUS complication.

    We report a case of isolated gastrointestinal metastasis from breast lobular carcinoma, which mimicked primary anal cancer. In July 2000, an 88-year-old woman presented with infiltrating lobular cancer (pT1/G2/N2). The patient received postoperative radiotherapy and hormonal therapy. Four years later, she presented with an anal polypoid lesion. The mass was removed for biopsy. Immunohistochemical staining suggested a breast origin. Radiotherapy was chosen for this patient, which resulted in complete regression of the lesion. The patient died 3 years after the first manifestation of gastrointestinal metastasis. According to the current literature, we consider the immunohistochemistry features that are essential to support the suspicion of gastrointestinal breast metastasis, and since we consider the gastrointestinal involvement as a sign of systemic disease, the therapy should be less aggressive and systemic.

    Female sex workers have been disproportionately affected with HIV and anal sexual experience elevate their vulnerability. Anal intercourse has more risk of HIV transmission than vaginal intercourse for receptors that coupled with low condom and proper lubricant use behavior during anal sex. Besides majority of them did not understand HIV transmission risk of anal intercourse. In Ethiopia, studies on anal sexual experience is almost none existent, so the purpose of this study is to explored anal sexual experience and HIV transmission risk awareness among female sex worker in Dire Dawa, Eastern Ethiopia. Qualitative study with thematic analysis approach was conducted among 18 female sex workers and recruitment of study participants performed until saturation of information. The principal investigator conducted in-depth interviews using local language (Amharic) and it was recorded on audio recorder. Tape recorded data was transcribed and translated to English and entered into open code version 3.4 for coding and theme identification. Data collection conducted simultaneously with data analysis. Female sex workers practiced anal sex for different themes like financial influence, coercion, intentionally, peer pressure and as a sign of intimacy and love. Coercion, negative attitudes, poor awareness about HIV transmission risks of anal sex and protection capacity of condom and proper lubricants are the identified themes for not using condom and proper lubricants during anal sex by female sex workers. Inaccessibility and unavailability of health services for issues related to anal sex was the core reason for female sex workers' misperception and risk anal sexual experience. Female sex workers practiced anal sex without risk reduction approaches and they did not understand exacerbated risk of anal sex to HIV transmission. Stakeholders including ministry of health need to incorporate potential awareness raising tasks and programs about risk of anal sex and methods of risk

    Full Text Available The aim of this study was to investigate the clinical characteristics, treatment outcomes and psychological distress in patients with chronic idiopathic anal pain. The study was conducted on patients referred to Hangzhou Third Hospital for chronic anal pain from January, 2010 to December, 2014. Patient demographics, clinical history, anorectal physiology, and radiological imaging data were recorded for all patients. The treatment outcome was noted for patients treated and followed up for more than 6 month at the present unit. Ninety-six patients with mean age of 45.1 years (range, 17-82 were studied. Seventy-one patients (74.0% had functional anorectal pain(FARP. The main complaints were dull, sharp, stabbing, or spasm pain. Among all patients, 34.3% reported that their pain radiated into other locations. Fifty-one patients (53.1% had bowel dysfunction, while 28.1% patients had urinary dysfunction. The common factors associated with pain relief were day time, lying down and warm water baths; the factors that contributed to aggravated pain were night time, defecation or sitting. 92.7% (89/96 of patients reported symptoms of psychological disturbance. FARP patients exhibited increased depression than non-FARP patients(P<0.05. In addition, female patients were more likely to have depression than male patients (P<0.05. The overall pain treatment success rate was 55.2% (53/96. The pain treatment outcome was better in non-FARP patients than in FARP patients(χ2=3.85, P<0.05. Conclusively, chronic idiopathic anal pain is a complex clinical symptom, involving pelvic floor muscles, the nervous system, endocrine system, and the patients’ psychological conditions. Further research is needed to improve diagnosis and treatment for patients with chronic idiopathic anal pain.

    Research Highlights: Human papillomaviruses cause anal intraepithelial neoplasia (AIN). Digital image processing was carried out to classify the grades of AIN quantitatively. The fractal dimension as well as grey value statistics was calculated. Higher grades of AIN yielded higher values of the fractal dimension. An automatic detection system is feasible. - Abstract: It is well known that human papillomaviruses (HPV) induce a variety of tumorous lesions of the skin. HPV-subtypes also cause premalignant lesions which are termed anal intraepithelial neoplasia (AIN). The clinical classification of AIN is of growing interest in clinical practice, due to increasing HPV infection rates throughout human population. The common classification approach is based on subjective inspections of histological slices of anal tissues with all the drawbacks of depending on the status and individual variances of the trained pathologists. Therefore, a nonlinear quantitative classification method including the calculation of the fractal dimension and first order as well as second order image statistical parameters was developed. The absolute values of these quantitative parameters reflected the distinct grades of AIN very well. The quantitative approach has the potential to decrease classification errors significantly and it could be used as a widely applied screening technique.

    A paucity of research is available on patients' bowel symptom experiences and self-care strategies following sphincter-saving surgery for rectal cancer. Most research undertaken to date on patients' bowel symptoms following surgery for rectal cancer has been largely atheoretical. The purpose of this paper is to describe the process of choosing a theoretical framework to guide a study of patients' bowel symptoms and self-care strategies following sphincter-saving surgery for rectal cancer. As a result of a thorough literature review, we determined that the Symptom Management Theory provided the most comprehensive framework to guide our research. Copyright © 2013 Elsevier Inc.

    Sphincter of Oddi spasm from opioids has been documented, presenting as severe epigastric pain and potentially overlooked in a differential diagnosis. We present a case of sphincter of Oddi spasm from periarticular morphine in a patient under spinal anesthesia, causing severe distress and treated effectively with glucagon. It is important for anesthesiologists using opioids to consider it as a cause of perioperative pain and be familiar with treatment as it may be refractory by conventional use of opioids for pain relief. It is also important to consider the systemic effects of periarticular absorption, as evident by our case.

    Full Text Available Rectal cancer is the third most common site for cancer in the world, with a high morbidity and mortality. The new techniques for the treatment of low rectal cancer have been improved recently, allowing sphincter-sparing surgery to be available for more patients, with an optimal oncological and functional outcome. The most fundamental advance in rectal cancer surgery was the concept of total mesorectal resection (TME introduced by Heald in 1982. Association with neoadjuvant radio-chemotherapy determines regression of the disease by “down staging” the tumors and allows for sphincter-sparing surgery to be performed, with low recurrence rate and increased overall survival. We present the case of 48-year old woman who had low rectal resection with colorectal anastomosis for middle rectal cancer. The patient had a BMI of 29, was hypertensive, had uterine fibroids and underwent neoadjuvant radiotherapy. During the 4th postoperative day the patient developed an anastomotic leakage grade B which was spontaneously closed on the 15th postoperative day. The patient did not manifest fever or any other symptoms. Normal bowel function resumed on the 5th postoperative day. No recurrence was detected at the one-year follow-up.

    Obesity has been an independent risk factor for female stress urinary incontinence (SUI), the mechanism of this association remains unknown. The aim of this study is to validate the hypothesis that urethral dysfunction is a possible contributor to SUI in obese women. Ten Zucker Fatty (ZF) (ZUC-Lepr fa 185) and 10 Zucker Lean (ZL) (ZUC-Lepr fa 186) female rats at 12-week-old were used in this experiment. The urethral sphincter rings were harvested from the bladder neck through to the most proximal 2/3 regions. In the organ bath study, single pulses of electrical field stimulation (EFS) were applied. For the fatiguing stimulation, repeated multi-pulse EFS with 70 mA were applied at frequency of 5 Hz for 5 min. Caffeine-containing Krebs' solution was administrated to contract the urethra until the contraction began to reach a plateau for 10 min. We performed immunofluorescence staining of the urethra after the experiment was finished. Compared to ZL controls, ZF rats had significantly impaired muscle contractile activity (MCA) (P female rats had significantly impaired contractile properties of striated urethral sphincter, suggesting urethral dysfunction could be an important contributor to SUI in obesity. © 2016 Wiley Periodicals, Inc.

    The aim of this analysis was to compare the advantages of the anal fistula plug (AFP) with the mucosa advancement flap (MAF) for complex anal fistulas. Comparative studies of the efficacy of AFP and MAF were included. Two independent reviewers selected articles for inclusion. After information collection, a meta-analysis was performed using data on overall healing rates, complications, incontinences and recurrences. The quality of postoperative life and cost were also included with the clinical results. Ten studies included 778 patients who were divided into AFP and MAF groups in this meta-analysis. During the follow-up period, no significant difference in healing rates, complications and recurrences were found (P = 0.55, P = 0.78 and P = 0.23, respectively). The incontinence rate of AFP was lower than that of MAF (P = 0.04). The postoperative quality of life of AFP patients was superior to that of MAF patients. The AFP patients had less persistent pain of a shorter duration and shortened healing time and hospital stay. The treatment cost of AFP patient was lower than that of MAF. Compared to the MAF procedure, the AFP procedure has some advantages for complex anal fistulas, but more and large randomized clinical trials comparing the two procedures for fistula management need to be conducted. © 2016 Royal Australasian College of Surgeons.

  1. HPV infection and intraepithelial lesions from the anal region: how to diagnose?

    Directory of Open Access Journals (Sweden)

    Newton Sérgio de Carvalho

    Full Text Available In the last years, the prevalence of HPV infection in the anal region has increased, especially in some groups like homosexual and HIV-positive people. Since this infection can be associated with the development of squamous anal cancer due to its progression from HPV infection to anal intraepithelial neoplasia (AIN and finally to cancer, the screening and evaluation of these conditions are important. Anal cytology and high resolution anoscopy are good methods that are available and can be used. Although useful, these methods should be performed correctly and not indiscriminately in all patients. Patients for whom anal cytology screening is recommended are: HIV-infected patients, homosexuals, women who present with high-grade vulvar squamous intraepithelial neoplasia, vulvar cancer or cervical cancer. An abnormal anal cytology should be further evaluated with high resolution anoscopy.

    This study examines whether the anal fin undergoes secondary sexual development similar to other reproductive traits in salmonids. This hypothesis was tested by comparing the anal-fin size of female kokanee salmon Oncorhynchus nerka that were in the early and late stages of sexual development. Females in an advanced stage of maturation had significantly larger anal fins relative to females in an early state of maturation (+4-7%), indicating that the anal fin undergoes secondary sexual development. The magnitude of this secondary growth was comparable with snout length (+9-10%), which is known to undergo secondary sexual development in female salmonids. When morphological trait dimensions were compared between the sexes, the anal fin was the only morphological trait found to have a female-biased sexual size dimorphism. This is the first study to show that the anal fin of female salmonids undergoes secondary sexual development. © 2015 The Fisheries Society of the British Isles.

    The LINX ® magnetic sphincter augmentation system (MSA) is a surgical technique with short-term evidence demonstrating efficacy in the treatment of medically refractory or chronic gastroesophageal reflux disease (GERD). Currently, the Nissen fundoplication is the gold-standard surgical treatment for GERD. We are the first to systematically review the literature and perform a meta-analysis comparing MSA to the Nissen fundoplication. A comprehensive search of electronic databases (e.g., MEDLINE, EMBASE, SCOPUS, Web of Science and the Cochrane Library) using search terms "Gastroesophageal reflux or heartburn" and "LINX or endoluminal or magnetic" and "fundoplication or Nissen" was completed. All randomized controlled trials, non-randomized comparison study and case series with greater than 5 patients were included. Five hundred and forty-seven titles were identified through primary search, and 197 titles or abstracts were screened after removing duplicates. Meta-analysis was performed on postoperative quality of life outcomes, procedural efficacy and patient procedural satisfaction. Three primary studies identified a total of 688 patients, of whom 273 and 415 underwent Nissen fundoplication and MSA, respectively. MSA was statistically superior to LNF in preserving patient's ability to belch (95.2 vs 65.9%, p < 0.00001) and ability to emesis (93.5 vs 49.5%, p < 0.0001). There was no statistically significant difference between MSA and LNF in gas/bloating (26.7 vs 53.4%, p = 0.06), postoperative dysphagia (33.9 vs 47.1%, p = 0.43) and proton pump inhibitor (PPI) elimination (81.4 vs 81.5%, p = 0.68). Magnetic sphincter augmentation appears to be an effective treatment for GERD with short-term outcomes comparable to the more technically challenging and time-consuming Nissen fundoplication. Long-term comparative outcome data past 1 year are needed in order to further understand the efficacy of magnetic sphincter augmentation.

    Full Text Available Objective To investigate the mechanism and effect of columnar balloon dilatation therapy on treating patients with severe dysphagia caused by upper esophageal sphincter (UES achalasia after stroke. Methods Sixty -four patients with severe dysphagia caused by UES achalasia after stroke were diagnosed through Video Fluoroscopic Swallowing Study (VFSS and esophageal dynamics testing. The patients were randomly divided into control group (N = 32 and treatment group (N = 32. Patients in control group were treated with routine drug treatment and routine rehabilitation training, while patients in treatment group were treated with columnar balloon dilatation therapy on the basis of routine treatment. The treatment end point was either the patient resuming an oral diet or after 4-weeks treatment. All cases were evaluated by swallowing function of VFSS, high resolution manometry (HRM and scores of the severity of dysphagia before treatment and at treatment end point. Results Compared with before treatment, UES resting pressure (P = 0.000 and residual pressure (P = 0.000 were significantly decreased, peak pressure was significantly increased (P = 0.000, duration of relaxation was prolonged (P = 0.000, and scores of the severity of dysphagia were significantly increased (P = 0.000, 0.000 in both groups after treatment. Compared with control group, UES resting pressure (P = 0.001 and residual pressure (P = 0.000 were significantly decreased, peak pressure was significantly increased (P = 0.002, duration of relaxation was prolonged (P = 0.000, and scores of the severity of dysphagia were significantly increased (P = 0.000 in treatment group after treatment. Until the treatment end point or after 4-week treatment, the total effective rate in treatment group was significantly higher than that in control group [93.75% (30/32 vs. 81.25% (26/32; χ2 = 4.010, P = 0.000].

    To study the results of stem-cell therapy under a Compassionate-use Program for patients with recurrent anal fistulae. Under controlled circumstances, and approved by European and Spanish laws, a Compassionate-use Program allows the use of stem-cell therapy for patients with very complex anal fistulae. Candidates had previously undergone multiple surgical interventions that had failed to resolve the fistulae, and presented symptomatic recurrence. The intervention consisted of limited surgery (with closure of the internal opening), followed by local implant of stem cells in the fistula-tract wall. Autologous expanded adipose-derived stem cells were the main cell type selected for implant. The first evaluation was performed on the 8(th) postoperative week; outcome was classified as response or partial response. Evaluation one year after the intervention confirmed if complete healing of the fistula was achieved. Ten patients (8 male) with highly recurrent and complex fistulae were treated (mean age: 49 years, range: 28-76 years). Seven cases were non-Crohn's fistulae, and three were Crohn's-associated fistulae. Previous surgical attempts ranged from 3 to 12. Two patients presented with preoperative incontinence (Wexner scores of 12 and 13 points). After the intervention, six patients showed clinical response on the 8(th) postoperative week, with a complete cessation of suppuration from the fistula. Three patients presented a partial response, with an evident decrease in suppuration. A year later, six patients (60%) remained healed, with complete reepithelization of the external opening. Postoperative Wexner Scores were 0 in six cases. The two patients with previous incontinence improved their scores from 12 to 8 points and from 13 to 5 points. No adverse reactions or complications related to stem-cell therapy were reported during the study period. Stem cells are safe and useful for treating anal fistulae. Healing can be achieved in severe cases, sparing fecal

    Until recently, no studies have prospectively evaluated bowel function after sphincter-preserving surgery for rectal cancer with the use of a validated bowel function scoring system. The aim of this study was to investigate possible risk factors for altered bowel function after sphincter-preserving surgery. This was a prospective study. The study was conducted between January 2006 and May 2012 at the authors' institution. Patients who underwent sphincter-preserving rectal cancer surgery were recruited. Bowel function was assessed 1 day before (baseline) and at 1 year after sphincter-preserving surgery or temporary ileostomy takedown with the use of the Memorial Sloan Kettering Cancer Center questionnaire. Multivariable analysis was performed to identify the factors associated with altered bowel function after surgery. Overall, 266 patients were eligible for the analysis. The tumor was located in the upper, middle, and lower rectum in 68 (25.5%), 113 (42.5%), and 85 (32.0%) patients. Intersphincteric resection and temporary ileostomy were performed in 18 (6.8%) and 129 (48.5%) patients. The mean Memorial Sloan Kettering Cancer Center score was 64.5 ± 7.6 at 1 year after sphincter-preserving surgery or temporary ileostomy takedown. The Memorial Sloan Kettering Cancer Center score decreased in 163/266 patients (61.3%) between baseline and 1 year after surgery. Tumor location (p = 0.01), operative method (p = 0.03), anastomotic type (p = 0.01), and temporary ileostomy (p = 0.01) were associated with altered bowel function after sphincter-preserving surgery in univariate analyses. In multivariable analysis, only tumor location was independently associated with impaired bowel function after sphincter-preserving rectal cancer surgery. This study was limited by its nonrandomized design and the lack of measurement before preoperative chemoradiotherapy. We suggest that preoperative counseling should be implemented to inform patients of the risk of bowel dysfunction

    Full Text Available Gastric ulcerations in the region of antrum pylori represent a serious medical problem in humans and animals. Such localization of ulcers can influence the intrinsic descending nerve supply to the pyloric sphincter. The pyloric function is precisely regulated by intrinsic and extrinsic nerves. Impaired neural regulation could result in pyloric sphincter dysfunction and gastric emptying malfunction. The aim of the study was to determine the effect of gastric antral ulcerations on the density and distribution of intramural gastric descending neurons supplying the pyloric sphincter in pigs.The experiment was performed on 2 groups of pigs: healthy gilts (n=6 and gilts with experimentally induced peptic ulcers in the region of antrum pylori (n=6. Gastric neurons supplying pyloric sphincter were labeled using the retrograde neuronal tracing technique (20μl of Fast Blue tracer injected into the pyloric sphincter muscle. After a week survival period the animals were sacrificed and the stomachs were collected. Then, the stomach wall was cross-cut into 0.5cm thick sections taken in specified intervals (section I - 1.5cm; section II - 3.5cm; section III - 5.5cm; section IV - 7.5cm starting from the sphincter. Consecutive microscopic slices prepared from each section were analyzed under fluorescent microscope to count traced neurons. Obtained data were statistically analyzed. The total number of FB-positive perikarya observed within all studied sections significantly decreased from 903.3 ± 130.7 in control to 243.8 ± 67.3 in experimental animals. In healthy pigs 76.1 ± 6.7% of labeled neurons were observed within the section I, 23.53 ± 6.5% in section II and only occasional cells in section III. In experimental animals, as many as 93.8 ± 2.1% of labeled cells were observed within the section I and only 6.2 ± 2.2% in section II, while section III was devoid of such neurons. There were no traced perikarya in section IV observed in both groups of pigs

    Purpose: To analyze the impact of patient and treatment parameters in concurrent chemoradiation treatment for anal carcinoma. Methods and Materials: Retrospective review of 50 MO anal cancer patients treated from 1984-1994. Most patients received concurrent 5-FU, mitomycin, and radiation. Local control and disease-free/overall survival were determined and analyzed according to patient and treatment parameters. Results: With 43 month median follow-up, projected overall survival is 66% at 5 and 8 years. Disease-free survival is 67% at 5 years and 59% at 8 years. Local control is 70% at 5 and 8 years. Doses of ≥54 Gy are associated with improved 5-year survival (84 vs. 47%, p = 0.02), disease-free survival (74 v. 56%, p = 0.09), and local control (77 vs. 61%, p = 0.04). Although local control, disease-free survival, and overall survival were improved in patients whose overall treatment time was <40 days, this was not statistically significant. Outcome in the four patients with pretreatment hemoglobin (Hgb) <10 appeared worse with 3-year overall survival 50 vs. 68% (p = 0.07), disease-free survival 0 vs. 67% (p = 0.11), and local control 0 vs. 74% (p = 0.05). Projected 5-year overall survival, relapse-free survival, and local control in 4 HIV (+) patients is 0, 75, and 75%. Multivariate analysis reveals that dose (p 0.02) and Hgb (p = 0.05) independently affect local control, dose (p = 0.02) affects disease-free survival, and dose (p = 0.01), Hgb (p = 0.03), T-stage (p = 0.03), and HIV-status (0.07) independently influence overall survival. Conclusion: Radiation doses of ≥54 Gy are associated with significantly improved survival and local control in anal cancer patients treated with chemoradiation. Overall treatment times of less than 40 days are associated with a trend towards improved outcome, but this is not significant. Pretreatment hemoglobin <10 is associated with worse treatment outcome. Survival of HIV (+) patient is poor, but the majority of such patients

    Chronic anal fissures represent 15% of proctologic consultations, although their aetiopathogenesis is unclear and multifactorial. This study aims to identify the aetiopathogenesis, risk factor of recurrence after lateral subcutaneous internal anal sphincterotomy and existing correlation with sexual abuse, as sexual abuse accounts for over 21% of anal fissures. We retrospectively studied 80 cases of surgical (n = 54) and medical (n = 26) patients known with chronic anal fissure over eight months. We built an original questionnaire referring to the NorVold Abuse Questionnaire. Sixty cases were interviewed with only twenty filling the questionnaire themselves. Among the aetiological factors observed, as reported by these patients, we underlined chronic constipation 51 (64%), postoperative haemorrhoidectomy 15 (19%), sexual abuse 15 (19%), vaginal delivery and hysterectomy 10 (13%), traumatic anal sex 10 (13%), digital anal examination 4 (5%), anti-inflammatory non-steroid suppository 3 (4%), asthma with chronic cough 3 (4%). The recurrence rate reached 39% (31 cases, 13/26 (50%) in the medical group, against 18/54 (33%) in the surgical group. The 4/15 (27%) of sexual abuse happened in adulthood and 6/15 (40%) never disclosed this information. Sexual abuse is a significant aetiological factor of chronic anal fissures and it is to be suspected in cases of recurrence after anal sphincterotomy. For such cases, a multidisciplinary treatment is crucial to improve the prognosis of the disease. We recognise that the causality is difficult to prove and we cannot confirm that every sexually abused person could inevitably develop chronic anal fissure.

    Little data exist on the outcome of combined inflatable penile prosthesis and artificial urinary sphincter insertion for erectile dysfunction and stress urinary incontinence. We assessed patient outcomes for combined vs single device implantation at a single institution. We retrospectively reviewed the records of all patients who underwent inflatable penile prosthesis and artificial urinary sphincter insertion at our hospital from January 2000 to December 2011. A total of 55 combined procedures were performed compared to the single insertion of 336 inflatable penile prostheses and 279 artificial urinary sphincters. The surgical approach consisted of penoscrotal incisions for inflatable penile prostheses and transperineal incisions for artificial urinary sphincter cuff placement with a secondary lower abdominal incision for reservoir placement. Men treated with combined implantation had greater mean age and were at greater risk for prostate cancer diagnosis and treatment, and at lesser risk for Peyronie disease than men who received an inflatable penile prosthesis alone (each pprosthesis alone and the AUS alone (mean 218.1 vs 145.9 and 114.7 minutes, respectively, p0.05). Combined inflatable penile prosthesis-artificial urinary sphincter implantation and staged prosthesis implantation are feasible without an increased risk of adverse outcomes compared to implantation of a single prosthesis. Patients with concomitant erectile dysfunction and stress urinary incontinence should be counseled about the possible advantages of this surgical option, which include a single anesthesia event and faster resumption of sexual activity and urinary control.

    Fourteen patients were examined one to four years after cricopharyngeal myotomy that had been carried out because of dysfunction of the pharyngo-esophageal sphincter. Twelve patients were examined radiologically. Eleven of the 14 patients were clinically improved or cured. In two patients who were not improved, the underlying condition was a polymyositis. The other patients suffered from an idiopathic dysfunction. Because of the small numbers involved, no detailed statistical analysis was carried out. Nevertheless, our results indicate that: Cricopharyngeus myotomy produces marked improvement or cure in patients with idiopathic dysfunction. Weak propulsive peristalsis of the pharyngeal constrictors is a prognostic factor indicating a poor clinical result of surgery. There is little chance of clinical improvement in patients with polymyositis.

  15. Local recurrence after sphincter-saving resection for rectal and rectosigmoid carcinoma: Value of various diagnostic methods

    The authors reviewed 51 cases of local recurrence after sphincter-saving resection for rectal and rectosigmoid carcinoma to assess the sensitivity of current diagnostic procedures. A combination of followup serum CEA levels and rectoscopy was found to be most efficient during the first two years after surgery in terms of the time frequency, and location of the recurrence as well as the cost-benefit ratio. On the other hand, almost all recurrent lesions developed extraluminally, infiltrating the suture line secondarily; moreover, one fourth extended outside the bowel wall. Thus in addition to endoscopy, CT is useful as a means of defining the entire mass at the anastomosis as well as detecting pericolic recurrence and is essential if repeat resection is contemplated.

    Urinary incontinence (UI) is a major health problem causing a significant social and economic impact affecting more than 200million people (women and men) worldwide. Over the past few years researchers have been investigating cell therapy as a promising approach for the treatment of stress urinary incontinence (SUI) since such an approach may improve the function of a weakened sphincter. Currently, a diverse collection of SUI animal models is available. We describe the features of the different models of SUI/urethral dysfunction and the pros and cons of these animal models in regard to cell therapy applications. We also discuss different cell therapy approaches and cell types tested in preclinical animal models. Finally, we propose new research approaches and perspectives to ensure the use of cellular therapy becomes a real treatment option for SUI. Copyright © 2014 Elsevier B.V. All rights reserved.

    1. We have used selective tachykinin receptor agonists and antagonists to investigate the nature of the receptors mediating responses to endogenous and exogenous tachykinins in the rabbit iris sphincter preparation in vitro. 2. The NK1-selective agonist, substance P methyl ester, induced contraction with a pD2 of 9.16 indicating the presence of NK1 receptors. In confirmation, the NK1-selective antagonist, GR82334, competitively antagonized responses to substance P methyl ester with high affinity (pKB 7.46). 3. NK3 receptors also mediate contraction since NK3-selective agonists exhibited high potency, e.g. the pD2 of [Me-Phe7]-neurokinin B was 9.67, and their responses were not inhibited by GR82334 (10 microM). 4. NK2 receptor activation does not seem to contribute to contraction since the NK2-selective agonist [beta-Ala8]-neurokinin A(4-10) had relatively low potency (pD2 6.43), and the NK2-selective antagonists MEN10207 (1 microM) and L-659,877 (10 microM) were inactive or had low affinity, respectively. 5. GR82334 (1 microM) significantly inhibited responses to electrical field-stimulation of non-adrenergic non-cholinergic sensory nerves (3, 10 and 30 Hz), and caused a rightward shift of the log concentration-response curve to bradykinin (lateral shift ca. 1000 fold). Higher concentrations of GR82334 (10 microM) significantly attenuated responses to capsaicin (1-60 microM) whilst completely abolishing responses to field-stimulation (3, 10 and 30 Hz) and bradykinin (1 nM- 3 microM). 6. In conclusion, NK1 and NK3 receptor activation results in contraction of the rabbit iris sphincter. The contractile response following sensory nerve stimulation by bradykinin, capsaicin and electrical field stimulation results from NK1 receptor activation. PMID:8401912

    Transient lower esophageal sphincter relaxation (TLESR) is the major mechanism of gastroesophageal reflux, but the regulation of TLESR by stimuli in the esophagus is incompletely understood. We have recently reported that acid infusion in the esophagus substantially (by 75%) increased the number of meal-induced TLESR in healthy subjects. We concluded that the TLESR reflex triggered by gastric distention with meal was enhanced by the stimulation of esophageal nerves by acid. However, the possibilities that the acid infused into the esophagus acts after passing though lower esophageal sphincter in stomach to enhance TLESR, or that the acid directly initiates TLESR from the esophagus were not addressed. Here, we evaluated the effect of acid infusion into the proximal stomach on meal-induced TLESR (study 1) and the ability of acid infusion into the esophagus to initiate TLESR without prior meal (study 2). We analyzed TLESRs by using high-resolution manometry in healthy subjects in paired randomized studies. In study 1, we found that acid infusion into the proximal stomach did not affect TLESRs induced by standard meal. The number of meal-induced TLESRs following the acid infusion into the proximal stomach was similar to the number of meal-induced TLESRs following the control infusion. In study 2, we found that acid infusion into the esophagus without prior meal did not initiate TLESRs. We conclude that the increase in the meal-induced TLESRs by acid in the esophagus demonstrated in our previous study is not attributable to the action of acid in the stomach or to direct initiation of TLESR from the esophagus by acid. Our studies are consistent with the concept that the stimuli in the esophagus can influence TLESRs. The enhancement of TLESR by acid in the esophagus may contribute to pathogenesis of gastroesophageal reflux in some patients. © 2015 International Society for Diseases of the Esophagus.

    Full Text Available Os objetivos deste estudo foram avaliar a frequência de HPV anal em pacientes com neoplasia intraepitelial cervical (NIC, verificar a concordância entre os subtipos encontrados nos dois locais e investigar os fatores que influenciaram a ocorrência de HPV anal em mulheres com NIC sem evidências clínicas de imunodepressão. Foram avaliadas 52 mulheres com idades entre 16 e 72 anos e diagnóstico de neoplasia intraepitelial cervical graus I, II e III. A identificação do DNA (ácido desoxirribonucleico do HPV e de sete subtipos dos vírus foi realizada por meio da reação em cadeia da polimerase (PCR em material colhido no ânus e colo uterino. Foram pesquisados fatores que poderiam contribuir para a infecção anal, como paridade, número de parceiros, tabagismo, manipulação e coito anal e o tipo de doença ginecológica. Das 52 mulheres, foi diagnosticado HPV na região anal em 25 (48%, das quais 23 (44% também apresentavam HPV no colo uterino - resultado significativo para existência do HPV em portadoras de NIC. Em 16 (31% o HPV foi diagnosticado somente no colo uterino e em 11 (21% não foi identificado em colo ou ânus. Houve associação significativa nas variáveis paridade (p=0,02 e número de parceiros (p=0,04. Concluiu-se que: as mulheres com HPV genital têm mais probabilidade de serem acometidas por HPV anal; não há concordância unânime entre os subtipos do HPV do colo do útero e do ânus e a paridade e o número de parceiros contribuem para aumentar a incidência de HPV anal nas mulheres sem imunodeficiência e com HPV cervical.This study aims were to assess the frequency of HPV anal infection in patients with cervical intra-epithelial neoplasia (CIN, to find out the relation between the found subtypes, when present in both regions, and investigate factors that influenced the occurrence of anal HPV in women with CIN.
