Influence of Preoperative Educational Intervention for Patients Undergoing Fecal Ostomy Surgery: A Comparison Cohort Study.

PURPOSE: This aim of this study was to compare the impact on hospital stay and short-term overall complications prior to and following the introduction of an outpatient preoperative ostomy education program to an existing inpatient ostomy education program. DESIGN: A comparison cohort study. SUBJECTS AND SETTING: One hundred thirty-eight consecutive patients undergoing ostomy surgery were included. One group (n = 65, 47%) was given an experimental preoperative ostomy education intervention, along with standard care including a postoperative educational intervention during the initial hospital course. A second group (n = 73, 53%) received the same standardized education in the postoperative period. Data were collected from a single tertiary center located in Seville, Spain, during a 12-month period between July 2014 and June 2015. METHODS: Data were collected in 2 phases. Data from participants undergoing postoperative (standard) education were collected retrospectively. Data for the group receiving preoperative education were collective prospectively. Outcome variables were postoperative length of stay, surgical complications (severity was assessed by the Clavien-Dindo grading system), subsequent interventions, and readmission rates. RESULTS: Analysis indicated no differences between the average length of postoperative hospital stay (12.32 days in the preoperative education group vs 12.76 days in the postoperative education group, P = .401). In contrast, overall complications, mortality, and readmission rates were significantly higher in the preoperative education program group (P = .027, P = .047, and P = .046, respectively). CONCLUSIONS: Delivering a standardized educational intervention during the preoperative period versus postoperative education delivery during the ostomy surgery hospital course did not reduce length of stay. Analysis indicated that overall complications, mortality, and readmission rates were significantly higher in the preoperative education program group but we hypothesize that intervening factors may have influenced these outcomes.

Efficacy of Sacral Nerve Stimulation in Non-constipated Irritable Bowel Syndrome Patients: A Systematic Review.

BACKGROUND AND AIMS: Irritable bowel syndrome (IBS) is a prevalent disorder with a complex and heterogeneous physiopathology, including a dysregulation of gut-brain axis. Treatment for IBS is targeted to the predominant symptom and requires a multidisciplinary approach. This review aims to evaluate the efficacy and safety of sacral nerve stimulation in non-constipated IBS patients Methods: A literature search was carried out on MEDLINE, The Cochrane Central Register of Controlled Trials (CENTRAL) and Web of Science databases for all relevant articles. Quality of included papers was assessed using standardized guidelines Results: Of 129 initial citations, 7 articles met our predefined inclusion criteria, including five randomized trials, a pilot study and a descriptive follow-up study. Five of 7 studies reported a positive effect of sacral nerve stimulation on symptoms and quality of life improvement in non-constipated IBS patients. No study reported serious adverse events. CONCLUSIONS: Despite initial promising results of sacral nerve stimulation in non-constipated IBS patients, studies with larger sample sizes and longer follow-up are required.

Non-classical high harmonic generation in graphene driven by linearly-polarized laser pulses.

Recent studies in high-order harmonic generation (HHG) in solid targets reveal new scenarios of extraordinary rich electronic dynamics, in comparison to the atomic and molecular cases. For the later, the main aspects of the process can be described semiclassically in terms of electrons that recombine when the trajectories revisit the parent ion. HHG in solids has been described by an analogous mechanism, in this case involving electron-hole pair recombinations. However, it has been recently reported that a substantial part of the HHG emission corresponds to situations where the electron and hole trajectories do not overlap in space. According to the present knowledge, HHG from this imperfect recollisions reflects the quantum nature of the process, arising in systems with large Berry curvatures or for elliptically polarized driving fields. In this work, we demonstrate that imperfect recollisions are also relevant in the more general case. We show the signature of such recollisions in the HHG spectrum from monolayer graphene -a system with null Berry curvature- irradiated by linearly polarized driving fields. Our calculations also reveal that imperfect multiple-order recollisions contribute to the harmonic emission when electron-hole excursion times exceed one cycle of the driving field. We believe that our work adds a substantial contribution to the full understanding of the sub-femtosecond dynamics of HHG in solid systems.

Robotic abdominal wall repair: adoption and early outcomes in a large academic medical center.

Robotic-assisted abdominal wall repair (RAWR) has seen an exponential adoption over the last 5 years. Skepticism surrounding the safety, efficacy, and cost continues to limit a more widespread adoption of the platform. We describe our initial experience of 312 patients undergoing RAWR at a large academic center. A retrospective review of all patients undergoing any RAWR from July 1, 2016 to March 18, 2020 was completed. Patient specific, operation specific, and 30-day outcomes specific data were collected. Univariate analysis and multivariate logistic regression were used to assess factors associated with 30-day complications. There was a steady adoption of RAWR over the study period. A total of 312 patient were included, 138 (44%) were abdominal wall repairs and 174 (56%) were inguinal repairs. The mean age of the cohort was 54.2 years (SD 16), 69% were males, and the mean BMI was 29 kg/m2 (SD 4.8). There were two reported intraoperative events and nine operative conversions. 60 patients had at least one complication at 30-days. These include: 52 seromas, 4 hematomas, 2 surgical-site infections, 1 deep venous thrombus, and 1 recurrence at 30-days. BMI, type of hernia, and sex were not associated with complications at 30-days. The use of absorbable mesh, longer hospital stay, operative conversion, previous repair, and expert hernia surgeon were significant predictors of 30-day complications. Age, operative conversion, and previous repair were the only predictors of 30-day complications on multivariate regression. Our initial experience of 312 patients demonstrates the adoption and comparable short-term outcomes for a wide variety of robotic-assisted hernia repairs.

Decreasing Surgical Site Infection Associated with the Use of Circular Staplers During Roux-En-Y Gastric Bypass.

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been established as a leading treatment of obesity. Surgical site infections (SSIs) remain the most common complication. Objective: To compare the incidence of SSIs before and after the implementation of our technique. Methods: Our intraoperative technique limits enteric contact with the abdominal wall through a wound protector at the end-to-end anastomosis stapler port site, with enteric retrieval with a specimen bag followed by betadine irrigation. We analyzed our SSIs outcomes before and after implementation of our technique in all RYGB and laparoscopic sleeve-to-bypass conversions at our institution performed by two providers between January 1, 2009 to December 31, 2011 and January 1, 2019 to December 31, 2021. We compared patient age, sex, body mass index, American Society of Anesthesiologists class; and comorbidities including hypertension, diabetes, and hyperlipidemia. The χ2, Fischer exact, Wilcoxon Rank Sum tests, and multivariate analysis were performed. Results: Four hundred twenty-nine patients underwent LRYGB and sleeve-to-bypass conversion during the two study periods. Group 1 (162 patients, 37.76%) all underwent RYGB. Group 2 (267 patients, 62.24%) of whom 199 underwent RYGB and 68 underwent a laparoscopic sleeve-to-bypass conversion. The SSI rate was 9.26% in Group 1 and 2.62% in Group 2 (p = 0.002514). Statistical significance was also noted for operating room time (137 min vs 123 min, p = 0.02) and hospital length of stay (2 - 3 interquartile range vs 1 - 2 interquartile range, p = 0.04). Conclusion: We propose a safe, reproducible technique that significantly reduces SSI rates during LRYGB.

Feasibility and safety of calcium alginate hydrogel sealant for the treatment of cryptoglandular fistula-in-ano: phase I/IIa clinical trial.

AIM: Complex perianal fistulas pose a challenge to the surgeon since the fistulous tract must be eliminated without impairing continence. Although without strong scientific evidence, some bibliography has demonstrated the efficacy of some sealants in the treatment of anal fistulas. We aimed to assess the feasibility and safety of calcium alginate hydrogel injections into the fistulous tract as treatment for trans-sphincteric cryptoglandular fistulas. METHODS: A prospective, single-centre, case series of this novel technique was conducted in a level 3 Spanish hospital, including patients diagnosed with trans-sphincteric perianal fistulas and treated with a calcium alginate hydrogel sealant. A strict follow-up was performed by an independent surgeon at 1, 3, 6 and 12 months. The main outcome measures were feasibility, safety (number of adverse events) and efficacy of the treatment. RESULTS: Twenty patients were treated. The treatment was performed for all patients. Seven adverse events related to the injection product or the surgical procedure were identified. After a 12-month follow-up, 12 patients were completely cured and eight were not cured, with a greater response in the first 6 months. These findings were confirmed by endoanal ultrasound, with a Cohen's kappa concordance rate of 0.89. No statistically significant differences were observed in pain measured using the visual analogue scale, faecal incontinence measured using the Wexner scoring system, and quality of life analysed by the SF-36 Health Survey. CONCLUSION: The treatment was feasible, safe and with discrete satisfactory healing results. It also demonstrated an acceptable safety profile, without worsening of faecal incontinence, quality of life and pain following treatment.

Influence of robotics in surgical complication rate in elderly population with rectal cancer.

BACKGROUND: Rectal cancer surgery is a technically complex procedure. Moreover, short-term outcomes show high rate of complications especially in elderly and laparoscopic surgery has not demonstrated to be able to reduce this complication rate. Robotics has several advantages in pelvic surgical procedures, which could have an impact in complication rates in elderly patients. AIMS: The aim of our study is to demonstrate whether robotic surgery has any influence on the reduction of complications in the aged population undergoing rectal cancer. METHODS: We performed a retrospective analysis of a prospective database of 151 patients who underwent robotic surgery for rectal cancer. We divided our population into three groups: under 65-year-old, between 65- and 80-year-old and above 80-year-old. We recorded complications in each group intra and post procedure. RESULTS: The present study included 151 patients (94 males). Of them, 77 patients were under 66 year old, 63 patients were between 66 and 79 year old and 11 patients were 80 year old and above. The analysis showed conversion rates of 10.38%, 13.69%, 27.27%, and the complication rate of 23.4%, 23.8%, and 27.3% in each group. Univariate analysis showed no differences between the three groups. Nevertheless, there were statistical differences from BMI, ASA and neoadjuvant therapy. In multivariant analysis only neoadjuvant therapy was significant. CONCLUSIONS: Robotic approach does not decrease complications in elderly population and conversion is similar in these age groups. So we should not rule out robotic surgery in elderly patients, although we must select each case with a multidisciplinary approach.

Platelet-rich plasma (PRP) versus fibrin glue in cryptogenic fistula-in-ano: a phase III single-center, randomized, double-blind trial.

PURPOSE: To compare the clinical outcome of autologous platelet-rich growth factor (PRP) with commercial fibrin glue in the management of high cryptogenic fistulae-in-ano. METHOD: The study was conducted at a single center between July 2012 and July 2015 and performed as a phase III, randomized, double-blind comparison of autologously prepared PRP versus fibrin glue for cryptoglandular anal fistulae without active sepsis. Patients were assessed with clinical and endosonographic follow-up. Patients were followed up at 1 week and then at 3, 6, and 12 postoperative months. The primary outcome measure was the fistula healing rate (complete, partial, and non-healing) with secondary outcome measures assessing fistula recurrence, continence status, quality of life, and visual analog pain scores. RESULTS: Of the 56 enrolled patients, 32 were PRP-treated and 24 were fibrin-treated. The groups were well matched for fistula type with an improved overall healing rate for PRP-treated over fibrin-treated cases (71% vs. 58.3%, respectively; P = 0.608); a complete healing rate of 48.4% vs. 41.7%, respectively; and a partial healing rate of 22.6% vs. 16.7%, respectively. The median pain scores of PRP-treated patients were lower at the first visit with a greater initial pain decrease early during follow-up. Improvements in pain reduction impacted the quality of life measures (P = 0.035). All adverse events were minor and no patient experienced a negative impact on continence. CONCLUSION: Treatment of complex cryptoglandular anal fistula with autologous PRP is as effective as fibrin glue with less cost and no adverse effect on continence.

Incontinencia fecal en el paciente anciano. Revisión de conjunto / Fecal incontinence in older patients. A narrative review

La incontinencia fecal representa una de las principales causas de institucionalización en las últimas décadas de la vida de una persona, asociando además gran repercusión psicosocial y económica. La literatura muestra escasa evidencia cuando se trata de analizar de forma específica a este grupo de población, debido a la falta de uniformidad en la consideración de «paciente anciano» y en la dificultad de su detección y diagnóstico. El objetivo de este artículo ha sido realizar una revisión narrativa de los principales aspectos relacionados con la incontinencia fecal en el anciano y facilitar el manejo de estos pacientes. La asistencia para la defecación, las modificaciones dietéticas y el control de la consistencia de las deposiciones o el tratamiento farmacológico son en muchos casos medidas suficientes. No obstante, otras terapias como el biofeedback, la neuromodulación o el tratamiento quirúrgico no deben descartarse y han de ser valoradas de forma selectiva en pacientes ancianos

Fecal incontinence is one of the leading causes for the institutionalization of people in the last decades of life, associated with a great psychosocial and economic burden. The literature is scarce in this population group, due to the absence of universally accepted criteria to define "elderly patients" and difficulties in detection and diagnostic. The aim of this article was to conduct a narrative review of the main aspects related to fecal incontinence in older patients, providing management support. Toileting assistance, dietary change, controlling stool consistency and medical treatment can be used to treat these patients. Nevertheless, other therapies, such as biofeedback, neuromodulation or surgical treatment, can be considered in selected patients

Factibility and security study of the PICS-AF™ plug for the treatment of cryptoglandular anal fistula. / Estudio de factibilidad y seguridad del plug de colágeno (PICS-AF™) en el tratamiento de la fístula anal criptoglandular.

INTRODUCTION: The PICS-AF™ (Curaseal Inc.) device is a new plug made of collagen that has a retention system in the internal orifice. This pilot study was designed to assess both the feasibility and safety of this plug in the treatment of trans-sphincteric anal fístulas. METHODS: A total of 44 patients (34 men), with a mean age of 54.68±7.3, with trans-sphincteric anal fístulas were included in the study; 34 of them were analyzed. All patients were examined according to a strict preoperative protocol and until 6 months after surgery. The feasibility of the procedure and the adverse events were analyzed. RESULTS: Finally, 34 patients were operated on, and in 30 of them the plug was used. Therefore, the feasibility was calculated at 88%. There was a total of 16 adverse events, 4recorded as not related (3 mild and one moderate) and 12 related to the procedure or to the device implanted. Of these, 5were mild, 5moderate and 2severe. The majority of the events reported were related to proctalgia (4 patients) or infection at the implant site (4 patients). CONCLUSIONS: The present study indicates that the new collagen plug can be placed effectively and with an acceptable complication rate.

Learning curve in robotic rectal cancer surgery: current state of affairs.

INTRODUCTION: Robotic-assisted rectal cancer surgery offers multiple advantages for surgeons, and it seems to yield the same clinical outcomes as regards the short-time follow-up of patients compared to conventional laparoscopy. This surgical approach emerges as a technique aiming at overcoming the limitations posed by rectal cancer and other surgical fields of difficult access, in order to obtain better outcomes and a shorter learning curve. MATERIAL AND METHODS: A systematic review of the literature of robot-assisted rectal surgery was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The search was conducted in October 2015 in PubMed, MEDLINE and the Cochrane Central Register of Controlled Trials, for articles published in the last 10 years and pertaining the learning curve of robotic surgery for colorectal cancer. It consisted of the following key words: "rectal cancer/learning curve/robotic-assisted laparoscopic surgery". RESULTS: A total of 34 references were identified, but only 9 full texts specifically addressed the analysis of the learning curve in robot-assisted rectal cancer surgery, 7 were case series and 2 were non-randomised case-comparison series. Eight papers used the cumulative sum (CUSUM) method, and only one author divided the series into two groups to compare both. The mean number of cases for phase I of the learning curve was calculated to be 29.7 patients; phase II corresponds to a mean number 37.4 patients. The mean number of cases required for the surgeon to be classed as an expert in robotic surgery was calculated to be 39 patients. CONCLUSION: Robotic advantages could have an impact on learning curve for rectal cancer and lower the number of cases that are necessary for rectal resections.

Validation of a new scoring system: Rapid assessment faecal incontinence score.

AIM: To implement a quick and simple test - rapid assessment faecal incontinence score (RAFIS) and show its reliability and validity. METHODS: From March 2008 through March 2010, we evaluated a total of 261 consecutive patients, including 53 patients with faecal incontinence. Demographic and comorbidity information was collected. In a single visit, patients were administered the RAFIS. The results obtained with the new score were compared with those of both Wexner score and faecal incontinence quality of life scale (FIQL) questionnaire. The patient without influence of the surgeon completed the test. The role of surgeon was explaining the meaning of each section and how he had to fill. Reliability of the RAFIS score was measured using intra-observer agreement and Cronbach's alpha (internal consistency) coefficient. Multivariate analysis of the main components within the different scores was performed in order to determine whether all the scores measured the same factor and to conclude whether the information could be encompassed in a single factor. A sample size of 50 patients with faecal incontinence was estimated to be enough to detect a correlation of 0.55 or better at 5% level of significance with 80% power. RESULTS: We analysed the results obtained by 53 consecutive patients with faecal incontinence (median age 61.55 ± 12.49 years) in the three scoring systems. A total of 208 healthy volunteers (median age 58.41 ± 18.41 years) without faecal incontinence were included in the study as negative controls. Pearson's correlation coefficient between "state" and "leaks" was excellent (r = 0.92, P < 0.005). Internal consistency in the comparison of "state" and "leaks" yielded also excellent correlation (Cronbach's α = 0.93). Results in each score were compared using regression analysis and a correlation value of r = 0.98 was obtained with Wexner score. As regards FIQL questionnaire, the values of "r" for the different subscales of the questionnaire were: "lifestyle" r = -0.87, "coping/behaviour" r = -0.91, "depression" r = -0.36 and "embarrassment" r = -0.90, (P < 0.01). A multivariate analysis showed that all the scoring systems measured the same factor. A single factor may explain 80.84% of the variability of FI, so all the scoring systems measure the same factor. Patient's continence improves when RAFIS and Jorge-Wexner scores show low values and when the values obtained in the FIQL questionnaire are high. CONCLUSION: RAFIS is a valid and reliable tool to assess Faecal Incontinence.

Utilidad de la ecografía dinámica tridimensional en el estudio del suelo pélvico / The role of tridimensional dynamic ultrasound for pelvic floor evaluation

INTRODUCCIÓN: La ecografía endoanal dinámica (EEAD) en 3 dimensiones ha surgido en los últimos años como una alternativa a las pruebas existentes en el diagnóstico de las alteraciones del suelo pélvico. El objetivo de este trabajo es determinar la utilidad de la ecodefecografía en el diagnóstico y evaluación de los pacientes que presentan síntomas de obstrucción defecatoria, así como mostrar los resultados obtenidos tras su implementación en una unidad de suelo pélvico. MÉTODOS: Estudio retrospectivo que analiza a 66 pacientes (61 mujeres), con una edad media de 55 años (19-83). Se realizó una EEAD y se correlacionó con los síntomas y los hallazgos exploratorios en consulta. Se realizó tanto un estudio descriptivo como inferencial, así como un índice Kappa para buscar correlación entre la exploración física y la EEAD. RESULTADOS: Los motivos de consulta fueron: síndrome de obstrucción defecatoria (SOD) 36 pacientes (54,5%), prolapso de órganos pélvicos (POP) 27 pacientes (40,9%) y SOD junto con POP 3 pacientes (4,5%). La correlación de ambos grupos indica que la EEAD diagnostica más pacientes con rectocele grado III, enteroceles y anismos que la combinación de exploración-manometría-proctoscopia-ecografía bidimensional (Kappa 0,26; 0,38 y 0,21; IC 95%: 0,07-1,00; 0,15-1,00 y 0,12-1,00, respectivamente) (p < 0,001). Por el contrario, la EEAD diagnostica menos descensos del periné (Kappa 0,28; IC 95% 0,12-1,00). CONCLUSIÓN: La ecografía dinámica puede tener un papel relevante como prueba complementaria en el paciente con enfermedad del suelo pélvico, ya que permite diagnosticar procesos que mediante la inspección, la exploración física y la manometría pasarían desapercibidos

INTRODUCTION: Dynamic endoanal ultrasound has emerged in recent years as a test that could replace the now existing tests in the diagnosis of pelvic floor disorders. The aim of this paper is to determine the usefulness of echodefecography in the diagnosis and evaluation of patients with symptoms of anorrectal obstruction, and show the results obtained after its implementation in a pelvic floor unit, as a complementary tool that could replace conventional defecography. METHODS: In this retrospective study we analyzed 66 patients with a mean age of 55 years (19-83), 61 women (92%). All dynamic ultrasound was performed in 3 dimensions and was correlated with symptoms and physical findings in the consultation. A descriptive and inferential study was performed to find a kappa correlation between physical examination and echodefecography. RESULTS: The reasons for consultation were: Anorrectal obstruction syndrome 36 patients (54.5%), pelvic organ prolapse 27 patients (40.9%), and anorrectal obstruction syndrome along with pelvic organ prolapse 3 patients (4.5%). The correlation of the 2 groups indicated that echodefecography diagnosed more patients with grade III rectocele, enteroceles, and anismus than the combination of scan-ultrasound-manometry-proctoscopy (Kappa 0.26, 0.38 and 0.21, 95% CI: from 0,07 to 1.00, 0.15 to 1.00 and from 0.12 to 1.00, respectively) (P<.001). Conversely, echodefecography diagnosed less perineal descense (Kappa 0.28, 95% CI: 0.12 to 1.00). CONCLUSIONS: Dynamic anal ultrasonography may have a role as a complementary test in patients with pelvic floor disorders, achieving diagnoses that would go undetected by inspection, physical examination and manometry
