Pelvic floor dysfunction after intervention, compared with expectant management, in prolonged second stage of labour: A population-based questionnaire and cohort study.

OBJECTIVE: To investigate the effect of vacuum extraction (VE) or caesarean section (CS), compared with expectant management, on pelvic floor dysfunction (PFD) 1-2 years postpartum in primiparous women with a prolonged second stage of labour. DESIGN: A population-based questionnaire and cohort study. SETTING: Stockholm, Sweden. POPULATION: A cohort of 1302 primiparous women with a second stage duration of ≥3 h, delivering from December 2017 to November 2018. METHODS: The 1-year follow-up questionnaire from the Swedish National Perineal Laceration Register was distributed 12-24 months postpartum. Exposure was VE or CS at 3-4 h or 4-5 h, compared with expectant management. MAIN OUTCOME MEASURES: Pelvic floor dysfunction was defined as at least weekly symptoms of urinary incontinence, pelvic organ prolapse or a Wexner score of ≥4. The risk of PFD was calculated using Poisson regression with robust variance estimation, presented as crude and adjusted relative risks (RRs and aRRs) with 95% confidence intervals (95% CIs). The implication of obstetric anal sphincter injury (OASI) on pelvic floor disorders was investigated through mediation analysis. RESULTS: In total, 35.1% of women reported PFD. Compared with expectant management, the risk of PFD was increased after VE at 3-4 h (aRR 1.33, 95% CI 1.06-1.65) and 4-5 h (aRR 1.34, 95% CI 1.05-1.70), but remained unchanged after CS. The increased risk after VE was not mediated by OASI. CONCLUSIONS: Pelvic floor dysfunction was common in primiparous women after a prolonged second stage, and the risk of PFD increased after VE but was unaffected by CS, compared with expectant management. If a spontaneous vaginal delivery eventually occurred, allowing an extended duration of labour did not increase the risk of PFD.

Incidence and risk factors of bowel dysfunction after minimally invasive rectal cancer surgery and discrepancies between the Wexner score and the low anterior resection syndrome (LARS) score.

PURPOSE: Bowel dysfunction after sphincter-preserving-surgery (SPS) impacts quality of life. The Wexner score (WS) and the low anterior resection syndrome (LARS) score (LS) are instruments for assessing postoperative bowel dysfunction. We analyzed the incidence of and risk factors for each symptom and examined the discrepancies between the two scores. METHODS: A total of 142 patients with rectal cancer, who underwent minimally invasive SPS between May, 2018 and July, 2019, were included. A questionnaire survey using the two scores was given to the patients 2 years after SPS. RESULTS: Tumor location and preoperative radiotherapy were independent risk factors for major LARS. Intersphincteric resection with a hand-sewn anastomosis (HSA) was an independent risk factor for high WS. Among the patients who underwent HSA, 82% experienced incontinence for liquid stools, needed to wear pads, and suffered lifestyle alterations. Of the 35 patients with minor LARS, only 1 had a high WS, and 80.0% reported no lifestyle alterations. Among the 75 patients with major LARS, 58.7% had a low WS and 21.3% reported no lifestyle alterations. CONCLUSION: The results of this study provide practical data to help patients understand potential bowel dysfunction after SPS. The discrepancies between the WS and LS were clarified, and further efforts are required to utilize these scores in clinical practice.

Wexner score and quality of life in women with obstetric anal sphincter injury.

INTRODUCTION AND HYPOTHESIS: Obstetric anal sphincter injury causes anal incontinence in half of the women affected. However, most symptoms are mild. The objective of this study was to evaluate the prevalence of anal incontinence and quality of life in women at long term after delivery with obstetric anal sphincter injury. We also wanted to identify a relevant cutoff level of the Wexner score (also known as the Cleveland Clinic Incontinence Score) to indicate affected quality of life in these women. METHODS: We performed a population-based questionnaire cohort study with prospective follow-up, including all women in Denmark with obstetric anal sphincter injury and one subsequent delivery between 1997 and 2005. We performed uni- and multivariate analyses and calculated the area under the ROC curve. RESULTS: In Denmark, 3885 women had an obstetric anal sphincter injury in their first delivery and a second delivery between 1997 and 2005 and no subsequent deliveries until 2010-2011. Questionnaires were sent to 3259 eligible women, and the response rate was 74.6%. In total, 2004 women could be included in the final analyses. Of these, 29.2% (n = 584) reported affected quality of life due to anal incontinence at long-term follow-up. We found that all symptoms of anal incontinence were associated with affected quality of life. The median age at follow-up was 40.3 years. The area under the ROC curve was 0.96 (95% CI 0.95-0.97) with a sensitivity of 0.94 (95% CI 0.92-0.96) and a specificity of 0.85 (95% CI 0.84-0.87) corresponding to an optimal cutoff level of the Wexner score of ≥ 2 to identify women with affected quality of life due to anal incontinence. CONCLUSIONS: In women with obstetric anal sphincter injury, 29% reported affected quality of life due to anal incontinence at long-term follow-up, and we found a low Wexner score cutoff level of ≥ 2 to identify women with affected quality of life.

Strong agreement between interview-obtained and self-administered Wexner and St. Mark's scores using a single questionnaire.

INTRODUCTION AND HYPOTHESIS: St Mark's incontinence score (SMIS) and the Wexner score have been constructed and validated as interview-based scoring systems. We developed a single questionnaire from which a separate SMIS or Wexner score could be derived. This study aimed to demonstrate the level of agreement between self-administered (sSMIS and sWexner) and interview-based (iSMIS and iWexner) scores using this questionnaire. METHODS: One hundred five consecutive patients (30 male) seen in the incontinence outpatient clinics at the Østfold Hospital Trust, Sarpsborg, and University Hospital of North Norway, Tromsø, completed the self-administered incontinence questionnaire prior to the appointment. Following clinical investigation, the patients were interviewed about their symptoms according to the SMIS and Wexner scores, with the interviewers blinded to the results from self-reported questionnaire. Agreement between total scores and between subscores of the various items were determined using interclass correlation coefficient (ICC) and kappa statistics, respectively. RESULTS: The self-administered questionnaire was incomplete in six cases (5.7%) and the interview-based was incomplete in two cases. Agreement was almost perfect between the iSMIS and sSMIS and between the iWexner score and sWexner score (ICC 0.90 and 0.92, respectively). Agreement was substantial to almost perfect for all items in both scoring systems, with kappa values ranging from 0.64-0.94. Mean iSMIS was 9.48 versus 9.53 for sSMIS (p = 0.90) and 8.26 versus 8.44 for the iWexner and sWexner score, respectively (p = 0.42). CONCLUSION: The SMIS and Wexner scores can be completed by the patients using a single questionnaire, and the derived SMIS and Wexner scores are highly consistent with scores obtained by interview.

Long Term Results of Modified Intersphincteric Resections for Low Rectal Cancer: A Single Center Experience.

BACKGROUND AND OBJECTIVES: The objective of this article is to evaluate the long-term oncological and functional outcomes following modified intersphincteric resections (ISR) for low rectal cancer. The modified technique consisted of the abandonment of colonic J-pouches, transverse coloplasty, or defunctioning temporary stoma in favor of a direct handsewn coloanal anastomosis (CAA). MATERIAL AND METHODS: Sixty consecutive patients with type II and III (juxta-anal or intra-anal) low rectal tumors underwent modified ISR by the same surgical team and were followed for a period of five years. Functional outcomes using the Wexner Score, postoperative complications, recurrence rates, morbidity, and mortality rates were assessed. RESULTS: The five-year survival rate was 93.3% with a disease-free interval at three years of 98%. Morbidity was 15% (n = 9) consisting of intestinal wall necrosis (n = 6), stenosis (n = 2), and sacral metastasis (n = 1). The Wexner score values were, at 1 year, 8.5 (range, 4-13); at three years 7.2 (range, 2-11); and at 5 years 6.7 (range, 2-12). A second surgery was needed in only one case that showed postoperative transmural necrosis of the colonic wall. CONCLUSIONS: In highly selected patients with type II or III low rectal tumors and proper preoperative imaging staging, ISR might be a viable alternative to other techniques such as abdominoperineal resection and low anterior resection, both from a functional and an oncological perspective.

Validity and reliability of a Lithuanian version of low anterior resection syndrome score.

BACKGROUND: Up to 90 % of patients undergoing low anterior resection complain of increased daily bowel movements, urgency, and a variable degree of incontinence. A symptom-based scoring system for bowel dysfunction after low anterior resection for rectal cancer has recently been developed and validated. The aim of our study was to adapt the low anterior resection syndrome (LARS) scale questionnaire to the Lithuanian language, and assess its psychometric properties. METHODS: The LARS questionnaire was translated into Lithuanian by the Scientific Advisory Committee of the Medical Outcomes Trust using a standard procedure of double-back translation. The Lithuanian version of the LARS (LARS-LT) questionnaire was completed by 111 patients who underwent low anterior resection with total mesorectal excision in the period from January 1, 2008, to December 31, 2012, at the National Cancer Institute. An anchor question from the Wexner score assessing the impact of bowel function on lifestyle was included. A subgroup of 20 patients completed the LARS-LT questionnaire twice. Validity was tested using a factor analysis, and internal reliability was estimated using the Cronbach's alpha and intraclass correlation coefficients. RESULTS: Twenty-seven patients (25 %) had no LARS, 26 (24 %) had minor LARS, and 55 (56 %) had major LARS. The response rate was 60.7 %. The LARS-LT showed significantly high reliability and internal consistency [Cronbach's α = 0.88, interclass correlation coefficient-0.86 (0.71-0.98)]. The LARS score showed significant correlations with the lifestyle question (p < 0.05). It could not detect differences between female and male patient groups (p = 0.33), patients' age (p = 0.45), patients who had/had not undergone radiation therapy (p = 0.07), and those in whom the distal edge of the tumor was close to or far from the anal verge (p = 0.17). CONCLUSIONS: The Lithuanian version of the LARS-LT shows acceptable psychometric properties and can be considered a valuable and specific instrument to assess bowel function in rectal cancer patients, both for research purposes and in clinical practice.

Evaluating the clinical application and effect of acupuncture therapy in anal function rehabilitation after low-tension rectal cancer surgery.

BACKGROUND: According to the indexes of serum and anal function, acupuncture therapy was applied to patients with low rectal cancer in order to avoid the occurrence of anal incontinence and reduce complications. AIM: To explore the clinical application and evaluate the effect of acupuncture therapy for anal function rehabilitation after low-tension rectal cancer surgery. METHODS: From the anorectal surgery cases, we selected 120 patients who underwent colorectal cancer surgery between January 2020 and December 2022 and randomly divided them into a control group (n = 60), observation group (n = 60), and control group after surgery for lifestyle intervention (including smoking cessation and exercise), dietary factor adjustment, anal movement, and oral loperamide treatment. The serum levels of motilin, 5-hydroxytryptamine, and vasoactive intestinal peptide (VIP), Wexner score for anal incontinence, and incidence of complications were compared between groups. RESULTS: After treatment, the VIP and 5-hydroxytryptamine levels in the observation group were lower than those in the control group (P < 0.05). The motilin level was higher than that in the control group (P < 0.05). Postoperative anal incontinence was better in the observation group than in the control group (P < 0.05). The incidence of complications in the observation group was 6.67%, which was significantly lower than that in the control group (21.67%; P < 0.05). CONCLUSION: Acupuncture therapy has a positive effect on the rehabilitation of anal function after low-tension rectal cancer surgery; it can effectively help to improve the serum indices of patients, avoid the occurrence of anal incontinence, and reduce the incidence of complications. Popularizing and applying it will be valuable.

Investigating anorectal function using postoperative MRI-based fibrosis score in patients with locally advanced rectal cancer receiving neoadjuvant chemoradiotherapy: a two-center study.

PURPOSE: This study aimed to develop a postoperative MRI-based fibrosis scoring system and to assess its correlation with anorectal function in locally advanced rectal cancer (LARC) cases administered neoadjuvant chemoradiotherapy (nCRT). METHODS: Pathologically confirmed LARC cases administered nCRT and radical resection were assessed retrospectively. Based on postoperative magnetic resonance imaging (MRI) findings, anastomotic fibrosis score (AFS) and perirectal fibrosis score (PFS) were determined to evaluate the extent of fibrosis. The Wexner continence score for anorectal function was obtained 2 years postoperatively and assessed for correlation with MRI fibrosis scores. The cases were divided into 2 groups by the median Wexner score. Univariable and multivariable analyses were adopted for building a nomogram model, whose diagnostic performance was estimated by receiver operating characteristic (ROC) and decision curve analyses (DCA). RESULTS: Finally, 144 patients with LARC were included in cohort 1 (training set). 52 patients were enrolled in cohort 2 (external validation set). Spearman correlation analysis indicated that AFS and PFS were positively correlated with the Wexner score. Univariable and multivariable analyses revealed age, tumor height, AFS, and PFS were independent predictors of anorectal function. The nomogram model achieved a good diagnostic performance, with AUCs of 0.800 and 0.827 in the training and validation sets, respectively; its predicting value was also confirmed by DCA. CONCLUSION: The present study showed AFS and PFS derived from postoperative MRI are positively correlated with Wexner score. In addition, the new scoring system was effective in predicting anorectal function in LARC cases administered nCRT.

Short and long term results of anatomical reconstruction of perineal body and sphincter complex in obstetric anal sphincter injuries.

Objectives: The effective way to reduce the risk of fecal incontinence (FI) in primary repaired obstetric anal sphincter injuries (OASIS) patients is to accurately detect the injury and provide complete anatomical reconstruction. The aim of the study was to evaluate the short-term and long-term results of OASIS cases that were diagnosed by an experienced surgical team and whose perineal body and anal sphincters were reconstructed separately. Material and Methods: Sixteen patients that required consultations due to anal sphincter damage during vaginal delivery and underwent anatomical reconstruction due to Grade 3c and Grade 4 sphincter damage between 2007 and 2019 were included in the study. These cases were divided into three groups [Group 1 (≤12 months), Group 2 (12-60 months), Group 3 (≥60 months)] according to the time elapsed until anal manometry, and incontinence questionnaires were conducted in the postoperative period. Recto-anal inhibitory reflex (RAIR), mean resting (IB) and squeezing (SB) pressures were measured by anal manometry. Anal incontinence (AI) and FI rates were determined by questionnaires. Anal sphincter damage repair techniques (overlapping, end-to-end) were determined. These parameters were compared between the three groups. Results: Mean age of the patients was 27.5 (16-35) years. Six (37.5%) patients had Grade 3c, while 10 (62.5%) had Grade 4 injury. The overall mean RP and SP were 35 (26-56) mmHg and 67 (31-100) mmHg, respectively. Mean RP and SP were 46/67 mmHg, 33.5/75.5 mmHg, and 37.5/70.5 mmHg in Groups 1, 2, and 3 respectively. There was no difference between the three groups in terms of mean RP and SP (p= 0.691, p= 0.673). The rate of AI and FI in all patients were 18.75% and 12.5%, respectively while the rate of severe AI incontinence was 6%. Severe AI was observed in 1 (16.7%) case in Group 1, mild AI was observed in 1 (25%) case in group 2, and in 1 (16.7%) case in Group 3. RAIR was positive in all patients. In Group 1, 5 (83.3%) patients underwent overlapping repair, and in Group 3, 6 (100%) patients underwent end-to-end repair. This difference was statistically significant (p= 0.011). Conclusion: In vaginal births, evaluation of anal sphincter damage, determination of perineal body structures and anal sphincters separately and performing anatomical reconstruction when needed significantly reduce the rate of FI in the short and long term.

Correlations of obstetric anal sphincter injury (OASIS) grade, specific symptoms of anal incontinence, and measurements by endoanal and transperineal ultrasound.

PURPOSE: The aim of the study was to investigate the association between the initial grade of obstetrical anal sphincter injury (OASIS), and Wexner score parameters, with ultrasonographic findings by endoanal ultrasound (EAUS, golden standard) and transperineal ultrasound (TPUS) 6 months post-partum. METHODS: Fifty-nine women after primary repair of OASIS were included at Helsingborg Hospital, Sweden, 2016-2017. Six months post-partum the women filled in a questionnaire regarding symptoms of anal incontinence by the Wexner score and were scanned with EAUS and TPUS (resting state and contracting state) for classification of the residual defect by a modified Starck score. RESULTS: Correlations were found between the OASIS grade and residual defects; length (rs = 0.41, P = 0.003), depth (rs = 0.38, P = 0.006) and angle (rs = 0.40, P = 0.004) of the external anal sphincter (EAS) measured with TPUS in resting state. Using EAUS, correlation between OASIS grade and EAS depth (rs = 0.35, P = 0.007) and angle (rs = 0.37, P = 0.004) were similar, but there was no correlation with length (rs = 0.20, P = 0.14). Between incontinence to gas and the angle of the residual defect in the IAS using TPUS in resting state, correlation was moderate (rs = 0.42, P = 0.003). Regarding incontinence to liquid stool, measurements by TPUS in resting state of EAS residual defect depth (rs = 0.46, P < 0.001) and angle (rs = 0.44, P = 0.001) also correlated moderately. Both corresponding correlations using EAUS were weaker. CONCLUSION: Defects measured with EAUS and TPUS six months post-partum correlated to initial OASIS grade and symptoms of anal incontinence. Specific symptoms correlated with specific anatomical defects, and TPUS was not an inferior method to EAUS.

Application of trinity new model home nursing in postoperative management of children with Hirschsprung's disease.

OBJECTIVE: To explore the application effect of Trinity new model home nursing in postoperative management of children with Hirschsprung's disease (HD). METHODS: A retrospective control research was designed, including 80 HD children underwent surgical treatment. According to the nursing model, the children were divided into control group (n=40) and observation group (n=40). They received conventional nursing and Trinity home nursing intervention respectively. The defecation function and quality of life, scores of self-rating anxiety scale (SAS) and family caregiver task inventory (FCTI), incidence of complications and nursing satisfaction before surgery, 3 and 6 months after surgery between the two groups were compared. RESULTS: Compared with the control group, the children in the observation group had lower Wexner constipation and fecal incontinence scores at 3 and 6 months after surgery (both P<0.001), while the children's quality of life generic core scale (PedsQLTM4.0) scores at 6 months after operation were higher than those in the control group (P<0.001). The SAS and FCTI scores of family members in the observation group were lower than those in the control group after intervention (all P<0.001). Compared with the control group, the observation group had lower total incidence of complications and higher nursing satisfaction (all P<0.05). CONCLUSION: Trinity new model home nursing can effectively increase the intestinal management quality of children undergoing HD surgery, improve their defecation function and quality of life, and reduce the risk of complications.

Tools for fecal incontinence assessment: lessons for inflammatory bowel disease trials based on a systematic review.

BACKGROUND: Fecal incontinence is a disabling condition affecting up to 20% of women. OBJECTIVE: We investigated fecal incontinence assessment in both inflammatory bowel disease and non-inflammatory bowel disease patients to propose a diagnostic approach for inflammatory bowel disease trials. METHODS: We searched on Pubmed, Embase and Cochrane Library for all studies on adult inflammatory bowel disease and non-inflammatory bowel disease patients reporting data on fecal incontinence assessment from January 2009 to December 2019. RESULTS: In total, 328 studies were included; 306 studies enrolled non-inflammatory bowel disease patients and 22 studies enrolled inflammatory bowel disease patients. In non-inflammatory bowel disease trials the most used tools were the Wexner score, fecal incontinence quality of life questionnaire, Vaizey score and fecal incontinence severity index (in 187, 91, 62 and 33 studies). Anal manometry was adopted in 41.2% and endoanal ultrasonography in 34.0% of the studies. In 142 studies (46.4%) fecal incontinence evaluation was performed with a single instrument, while in 64 (20.9%) and 100 (32.7%) studies two or more instruments were used. In inflammatory bowel disease studies the Wexner score, Vaizey score and inflammatory bowel disease quality of life questionnaire were the most commonly adopted tools (in five (22.7%), five (22.7%) and four (18.2%) studies). Anal manometry and endoanal ultrasonography were performed in 45.4% and 18.2% of the studies. CONCLUSION: Based on prior validation and experience, we propose to use the Wexner score as the first step for fecal incontinence assessment in inflammatory bowel disease trials. Anal manometry and/or endoanal ultrasonography should be taken into account in the case of positive questionnaires.

Survival and functional and oncological outcomes following intersphincteric resection for low rectal cancer: short-term results.

Objective This study was performed to evaluate the 1-year survival rate and functional outcomes of 20 patients who underwent intersphincteric resection (ISR) for low rectal cancer. Methods Twenty patients who underwent ISR for low rectal cancer were followed up for 1 year. Complications, functional outcomes objectified by the Wexner score, and oncological outcomes were assessed. Results The short-term survival rate was 100%. The median Wexner score was ≤10 in all patients at 12 months after surgery. Signs of local recurrence were absent, and antigen levels remained within the reference ranges 1 year postoperatively. Conclusions ISR is a feasible alternative in highly selected patients who primarily refuse a colostomy bag and present with type II or III tumors. In the present study, patient-reported continence was satisfactory, and the absence of a colostomy bag increased patients' quality of life. The oncological outcomes were satisfactory at 1 year postoperatively.

Early pelvic floor muscle training after obstetrical anal sphincter injuries for the reduction of anal incontinence.

OBJECTIVES: 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. STUDY DESIGN: 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. RESULTS: 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). CONCLUSIONS: We recommend early (during the first month postpartum) PFMT after vaginal deliveries associated with OASIS. Rehabilitation should be carried out by a physiotherapist specialized in perineology in order to prevent medium-term functional consequences. A longer follow-up may be necessary to confirm the stability of results.

Laparoscopic pelvic organ suspension with mesh: a modified technique and primary results / Suspensão laparoscópica de órgão pélvico com malha: uma técnica modificada e resultados primários

Abstract Background: Pelvic organ prolapse recurrence rate is an important issue which impacts the patient's quality of life and results in a new surgical procedure. We use a new technique of laparoscopic pelvic organ suspension (rectal suspension) for pelvic organ prolapse treatment in our center. We evaluated the results of this technique, three months after surgery and at the time of study reporting. Methods: All patients with pelvic organ prolapse for whom laparoscopic pelvic organ prolapse had been done were evaluated. Data were collected from the patient's charts and their short term follow up 3 months after the surgery and their last follow up visit. Demographic, history, physical examination, Wexner's fecal incontinence score and Altomare's Obstructed Defecation Syndrome score, post-operation complications and patient's satisfaction were analyzed, retrospectively. Results: All patients were female with a mean age of 57 ± 11.43 years (range 32-86 years). Mean BMI was 26.1 ± 3.73. Nine patients had rectal bleeding (31%), 18 had prolonged or difficult defecation (62%), 16 had rectal prolapse (55.2%), 11 had gas incontinence (37.9%), 9 had liquid stool incontinence (31%), 5 had stool incontinence (17.2%), 9 had vaginal prolapse (31%), 23 had constipation (79.3%), 9 complaint of pelvic pain (31%), 9 had urge or stress urinary incontinence (31%) and 13 had dyspareunia (44.8%). Conclusions: In conclusion, we believe this procedure has good results in short term follow up (3 months after surgery), but a high recurrence rate in the middle term follow up. Therefore, this procedure is no longer recommended.

Resumo Introdução: A taxa de recorrência do prolapso de órgãos pélvicos é uma questão importante que afeta a qualidade de vida do paciente, resultando em um novo procedimento cirúrgico. Os autores adotaram uma nova técnica de suspensão laparoscópica de órgãos pélvicos (suspensão retal) no tratamento de prolapso de órgãos pélvicos. Os resultados dessa técnica foram avaliados três meses após a cirurgia e no momento do relato do estudo. Métodos: Todos os pacientes com prolapso de órgão pélvico submetidos a suspensão laparoscópica foram avaliados. Os dados foram coletados do prontuário do paciente, na visita de acompanhamento três meses após a cirurgia e na última visita de acompanhamento. Os dados demográficos, histórico médico, avaliação física, escore de incontinência fecal de Wexner, escore da síndrome da defecação obstruída de Altomare, complicações pós-operatórias e satisfação do paciente foram analisados retrospectivamente. Resultados: Todos os pacientes eram do sexo feminino, com média de idade de 57 ± 11,43 anos (variação de 32 a 86 anos). O índice de massa corporal médio foi de 26,1 ± 3,73. Nove (31%) pacientes apresentaram sangramento retal; 18 (62%), defecação prolongada ou difícil; 16 (55,2%), prolapso retal; 11 (37,9%), incontinência gasosa; nove (31%), incontinência fecal líquida, cinco (17,2%), incontinência fecal; nove (31%), prolapso vaginal; 23 (79,3%), constipação; nove (31%), queixa de dor pélvica; nove (31%), incontinência urinária de urgência ou esforço e 13 (44,8%), dispareunia. Conclusões: Os autores acreditam que este procedimento apresenta bons resultados no seguimento de curto prazo (três meses após a cirurgia), mas uma alta taxa de recorrência no acompanhamento a médio prazo. Portanto, esse procedimento não é mais recomendado.

Effects of vagus nerve preservation and vagotomy on peptide YY and body weight after subtotal gastrectomy.

AIM: To investigate the relationship between the function of vagus nerve and peptide YY(3-36) and ghrelin levels after subtotal gastrectomy. METHODS: We enrolled a total of 16 patients who underwent subtotal gastrectomy due to gastric cancer. All surgeries were performed by a single skilled surgeon. We measured peptide YY(3-36), ghrelin, leptin, insulin, growth hormone levels, and body weight immediately before and one month after surgery. RESULTS: Vagus nerve preservation group showed less body weight loss and less increase of peptide YY(3-36) compared with vagotomy group (-5.56 ± 2.24 kg vs -7.85 ± 1.57 kg, P = 0.037 and 0.06 ± 0.08 ng/mL vs 0.19 ± 0.12 ng/mL, P = 0.021, respectively). Moreover, patients with body weight loss of less than 10% exhibited reduced elevation of peptide YY(3-36) level, typically less than 20% [6 (66.7%) vs 0 (0.0%), P = 0.011, odd ratio = 3.333, 95% confidence interval (1.293, 8.591)]. CONCLUSION: Vagus nerve preservation contributes to the maintenance of body weight after gastrectomy, and this phenomenon may be related to the suppressed activity of peptide YY(3-36).

Excisional hemorrhoidal surgery and its effect on anal continence.

AIM: To investigate the role of anal cushions in hemorrhoidectomy and its effect on anal continence of the patients. METHODS: Seventy-six consecutive patients (33 men and 43 women) with a mean age of 44 years were included. They underwent Milligan-Morgan hemorrhoidectomy because of symptomatic third- and fourth-degree hemorrhoids and failure in conservative treatment for years. Wexner score was recorded and liquid continence test was performed for each patient before and two months after operation using the techniques described in our previous work. The speed-constant rectal lavage apparatus was prepared in our laboratory. The device could output a pulsed and speed-constant saline stream with a high pressure, which is capable of overcoming any rectal resistance change. The patients were divided into three groups, group A (< 900 mL), group B (900-1200 mL) and group C (> 1200 mL) according to the results of the preoperative liquid continence test. RESULTS: All the patients completed the study. The average number of hemorrhoidal masses excised was 2.4. Most patients presented with hemorrhoidal symptoms for more than one year, including a mean duration of incontinence of 5.2 years. The most common symptoms before surgery were anal bleeding (n = 55), prolapsed lesion (n = 34), anal pain (n = 12) and constipation (n = 17). There were grade III hemorrhoids in 39 (51.3%) patients, and grade IV in 37 (48.7%) patients according to Goligher classification. Five patients had experienced hemorrhoid surgery at least once. Compared with postoperative results, the retained volume in the preoperative liquid continence test was higher in 40 patients, lower in 27 patients, and similar in the other 9 patients. The overall preoperative retained volume in the liquid continence test was 1130.61 ± 78.35 mL, and postoperative volume was slightly decreased (991.27 ± 42.77 mL), but there was no significant difference (P = 0.057). Difference was significant in the test value before and after hemorrhoidectomy in group A (858.24 ± 32.01 mL vs 574.18 ± 60.28 mL, P = 0.011), but no obvious difference was noted in group B or group C. There was no significant difference in Wexner score before and after operation (1.68 ± 0.13 vs 2.10 ± 0.17, P = 0.064). By further stratified analysis, there was significant difference before and 2 months after operation in group A (2.71 ± 0.30 vs 3.58 ± 0.40, P = 0.003). In contrast, there were no significant differences in group B or group C (1.89 ± 0.15 vs 2.11 ± 0.19, P = 0.179; 0.98 ± 0.11 vs 1.34 ± 0.19, P = 0.123). CONCLUSION: There is no difference in the continence status of patients before and after Milligan-Morgan hemorrhoidectomy. However, patients with preoperative compromised continence may have further deterioration of their continence, hence Milligan-Morgan hemorrhoidectomy should be avoided in such patients.

Prevalencia de incontinencia fecal en personas que acuden a policlínicos de un hospital universitario / Frequency of fecal incontinence in ambulatory patients

Abstract Background: Fecal incontinence (FI) affects quality of life and is a cause embarrassment, hampering the collection of data about the problem. It is more common in older people and it is important to know risk the factors and scope of the problem. Aim: Determine the prevalence and risk factors associated to FI in a population of patients consulting in a health center. Material and Methods: A self-applied questionnaire was answered by a randomly selected sample of 1136 ambulatory patients aged 50 ± 15years (59% females), excluding those who consulted in colorectal surgery and gynecology. Demographic variables, obstetric history, history of anorectal surgery, anorectal symptoms, involuntary urine loss, and the FI Wexner or Cleveland Clinic Fecal Incontinence scores were recorded. Results: Thirty one percent of respondents had some degree of FI. In multivariate analysis presence of anorectal pain, urinary incontinence and number of vaginal deliveries were significantly associated with FI. Conclusions: Prevalence of FI in this study is similar, though slightly higher, to data reported in national and international publications.

Resumen Introducción: La incontinencia fecal (IF) es una entidad que afecta la calidad de vida y produce vergüenza, esto hace difícil la obtención de datos fidedignos en cuanto a su prevalencia. Dado el aumento de la población mayor en nuestro país y su relación con la aparición de IF, es importante conocer los factores de riesgo y magnitud del problema, para así realizar prevención además de un diagnóstico y tratamiento precoz. Objetivo: Determinar la prevalencia y los factores asociados a IF en personas que acuden a un centro de salud por otra causa. Material y Método: Se realizó una encuesta auto aplicada en el Hospital Clínico de la Universidad de Chile, entre mayo y junio de 2012. La muestra se seleccionó en forma aleatoria incluyendo pacientes mayores de 20 años que acudieron a diversos policlínicos, excluyéndose los policlínicos de coloproctología y ginecología. Se registraron variables demográficas, antecedentes obstétricos, antecedentes quirúrgico sanorrectales, sintomatología anorrectal, pérdida involuntaria de orina, y la escala de incontinencia fecal de Wexner o CCFIS. Resultados: De un total de 1.136 individuos, 59,2% eran mujeres y la edad promedio fue de 50,53 ± 15,49 años. Un 31,07% presentaba algún grado de IF. En el análisis multivariado la presencia de dolor e incontinencia de orina, así como el número de partos presentaron una asociación significativa con la IF. Conclusión: Las cifras de prevalencia de IF en este estudio son algo mayores con respecto a datos nacionales e internacionales.
