Socioeconomic Disparities in Anal Cancer: Effect on Treatment Delay and Survival.

BACKGROUND: Socioeconomic inequities have implications for access to health care and may be associated with disparities in treatment and survival. OBJECTIVE: To investigate the impact of socioeconomic inequities on time to treatment and survival of anal squamous-cell carcinoma. DESIGN: This is a retrospective study using a nationwide data set. SETTINGS: The patients were selected from the National Cancer Database and enrolled from 2004 to 2016. PATIENTS: We identified patients with stage I to III squamous-cell carcinoma of the anus who were treated with chemoradiation therapy. MAIN OUTCOMES MEASURES: Socioeconomic factors, including race, insurance status, median household income, and percentage of the population with no high school degrees, were included. The association of these factors with treatment delay and overall survival was investigated. RESULTS: A total of 24,143 patients who underwent treatment for grade I to III squamous-cell carcinoma of the anus were identified. The median age was 60 years, and 70% of patients were women. The median time to initiation of treatment was 33 days. Patients from zip codes with lower median income, patients with a higher percentage of no high school degree, and patients with other government insurance followed by Medicaid insurance had treatment initiated after 60 days from diagnosis. Kaplan-Meier survival analysis showed that the late-treatment group had worse overall survival compared to the early treatment group (98 vs 125 months; p < 0.001). LIMITATIONS: No detailed information is available about the chemoradiotherapy regimen, completion of treatment, recurrence, disease-free survival, and individual-level socioeconomic condition and risk factors. CONCLUSION: Patients from communities with lower median income, level of education, and enrolled in public insurance had longer time to treatment. Lower socioeconomic status was also associated with poorer overall survival. These results warrant further analysis and measures to improve access to care to address this disparity.

DESIGUALDADES SOCIOECONMICAS EN CASOS DE CNCER ANAL EFECTOS EN EL RETRASO DEL TRATAMIENTO Y LA SOBREVIDA: ANTECEDENTES:Las desigualdades socio-económicas tienen implicaciones en el acceso a la atención médica y pueden estar asociadas con disparidades en el tratamiento y la sobrevida.OBJETIVO:Indagar el impacto de las desigualdades socio-económicas sobre el tiempo de retraso en el tratamiento y la sobrevida en casos de carcinoma a células escamosas del ano (CCEA).DISEÑO:Estudio retrospectivo utilizando un conjunto de datos a nivel nacional.AJUSTES:Todos aquellos pacientes inscritos entre 2004 a 2016 y que fueron seleccionados de la Base Nacional de Datos sobre el Cáncer.PACIENTES:Identificamos pacientes con CCEA en estadíos I-III y que fueron tratados con radio-quimioterápia.PRINCIPALES MEDIDAS DE RESULTADOS:Se incluyeron factores socio-económicos tales como la raza, el tipo de seguro de salud, el ingreso familiar medio y el porcentaje de personas sin bachillerato de secundaria (SBS). Se investigó la asociación entre estos factores con el retraso en iniciar el tratamiento y la sobrevida global.RESULTADOS:Se identificaron un total de 24.143 pacientes que recibieron tratamiento para CCEA estadíos I-III. La mediana de edad fue de 60 años donde 70% eran de sexo femenino. La mediana del tiempo transcurrido desde el diagnóstico hasta el inicio del tratamiento fue de 33 días. Los pacientes residentes en zonas de código postal con ingresos medios más bajos, con un mayor porcentaje de individuos SBS y los pacientes con otro tipo de seguro gubernamental de salud, seguidos del seguro tipo Medicaid iniciaron el tratamiento solamente después de 60 días al diagnóstico inicial de CCEA. El análisis de Kaplan-Meier de la sobrevida mostró que el grupo de tratamiento tardío tuvo una peor supervivencia general comparada con el grupo de tratamiento precoz o temprano (98 frente a 125 meses; p <0,001).LIMITACIONES:No se dispone de información detallada sobre el tipo de radio-quimioterapia utilizada, ni sobre la finalización del tratamiento o la recurrencia, tampoco acerca de la sobrevida libre de enfermedad ni sobre las condiciones socio-económicas o aquellos factores de riesgo a nivel individual.CONCLUSIÓN:Los pacientes de comunidades con ingresos medios más bajos, con un nivel de educación limitado e inscritos en un seguro público tardaron mucho más tiempo en recibir el tratamiento prescrito. El nivel socio-económico más bajo también se asoció con una sobrevida global más baja. Los presentes resultados justifican mayor análisis y medidas mas importantes para mejorar el acceso a la atención en salud y poder afrontar esta disparidad. (Traducción-Dr. Xavier Delgadillo ).

Development of a Consensus-Derived Synoptic Operative Report for Rectal Prolapse: A Report From the Pelvic Floor Disorders Consortium.

BACKGROUND: Narrative operative reports may omit or obscure data from an operation. OBJECTIVE: To develop a synoptic operative report for rectal prolapse that includes core descriptors as developed by an international consensus of expert pelvic floor surgeons. DESIGN: Descriptors for patients undergoing rectal prolapse surgery were generated through review. Members of the Pelvic Floor Disorders Consortium were recruited to participate in a 3-round Delphi process using a 9-point Likert scale. Descriptors that achieved 70% agreement were kept from the first round, and descriptors scoring 40% to 70% agreement were recirculated in subsequent rounds. A final list of operative descriptors was determined at a consensus meeting, with a final consensus meeting more than 70% agreement. SETTINGS: This survey was administered to members of the Pelvic Floor Disorders Consortium. PATIENTS: No patient data are included in this study. MAIN OUTCOME MEASURES: Descriptors meeting greater than 70% agreement were selected. RESULTS: One hundred seventy-six surgeons representing colorectal surgeons, urogynecologists, and urologists distributed throughout North America (56%), Latin America (4%), Western Europe (29%), Asia (4%), and Africa (1%) participated in the first round of Delphi voting. After 2 additional rounds and a final consensus meeting, 16 of 30 descriptors met 70% consensus. Descriptors that met consensus were surgery type, posterior dissection, ventral dissection, mesh used, type of mesh used, mesh location, sutures used, suture type, pouch of Douglas and peritoneum reclosed, length of rectum imbricated, length of bowel resected, levatoroplasty, simultaneous vaginal procedure, simultaneous gynecologic procedure, simultaneous enterocele repair, and simultaneous urinary incontinence procedure. LIMITATIONS: The survey represents the views of members of the Delphi panel and may not represent the viewpoints of all surgeons. CONCLUSIONS: This Delphi survey establishes international consensus descriptors for intraoperative variables that have been used to produce a synoptic operative report. This will help establish defined operative reporting to improve clinical communication, quality measures, and clinical research. See Video Abstract .

Después de dos rondas adicionales y una reunión de consenso final, 16 de 30 descriptores alcanzaron un 70% de consenso. Los descriptores que alcanzaron consenso fueron: tipo de cirugía, disección posterior, disección ventral, malla utilizada, tipo de malla utilizada, ubicación de la malla, suturas utilizadas, tipo de sutura, cierre del fondo de saco de Douglas y peritoneo, longitud del recto superpuesto, longitud del intestino resecado, plastía de los elevadores , procedimiento vaginal simultáneo, procedimiento ginecológico simultáneo, reparación simultánea de enterocele y procedimiento simultáneo de incontinencia urinaria.LIMITACIONES:La encuesta representa las opiniones de los miembros del panel Delphi y puede no representar los puntos de vista de todos los cirujanos.CONCLUSIONES/DISCUSIÓN:Esta encuesta Delphi establece descriptores de consenso internacional para las variables intraoperatorias que se han utilizado para producir un protocolo operatorio sinóptico. Esto ayudará a establecer protocolos operativos definidos para mejorar la comunicación clínica, las medidas de calidad y la investigación clínica. (Traducción-Dr. Felipe Bellolio ).

Leukocyte subtyping predicts for treatment failure and poor survival in anal squamous cell carcinoma.

BACKGROUND: Anal squamous cell carcinoma (SCC) generally carries a favorable prognosis, as most tumors are highly sensitive to standard of care chemoradiation. However, outcomes are poor for the 20-30% of patients who are refractory to this approach, and many will require additional invasive procedures with no guarantee of disease resolution. METHODS: To identify the patients who are unlikely to respond to the current standard of care chemoradiation protocol, we explored a variety of objective clinical findings as a potential predictor of treatment failure and/or mortality in a single center retrospective study of 42 patients with anal SCC. RESULTS: Patients with an increase in total peripheral white blood cells (WBC) and/or neutrophils (ANC) had comparatively poor clinical outcomes, with increased rates of death and treatment failure, respectively. Using pre-treatment biopsies from 27 patients, tumors with an inflamed, neutrophil dominant stroma also had poor therapeutic responses, as well as reduced overall and disease-specific survival. Following chemoradiation, we observed uniform reductions in nearly all peripheral blood leukocyte subtypes, and no association between peripheral white blood cells and/or neutrophils and clinical outcomes. Additionally, post-treatment biopsies were available from 13 patients. In post-treatment specimens, patients with an inflamed tumor stroma now demonstrated improved overall and disease-specific survival, particularly those with robust T-cell infiltration. CONCLUSIONS: Combined, these results suggest that routinely performed leukocyte subtyping may have utility in risk stratifying patients for treatment failure in anal SCC. Specifically, pre-treatment patients with a high WBC, ANC, and/or a neutrophil-dense tumor stroma may be less likely to achieve complete response using the standard of care chemoradiation regimen, and may benefit from the addition of a subsequent line of therapy.

Open vs Minimally Invasive Approach for Emergent Colectomy in Perforated Diverticulitis.

BACKGROUND: Traditionally, perforated diverticulitis has been managed with an open approach, with a Hartmann procedure or a colectomy with primary anastomosis. Minimally invasive surgery is associated with postoperative advantages in the elective setting and may show a benefit in the emergent setting. OBJECTIVE: The aim of this study was to compare postoperative outcomes of open vs minimally invasive approaches for emergent perforated diverticulitis. DESIGN: This was a retrospective review of the American College of Surgeons National Surgical Quality Improvement Program targeted colectomy database using propensity score matching. SETTINGS: Interventions were performed in hospitals participating in the national database. PATIENTS: Patients who underwent emergent colectomy from 2012 to 2017 were included. Procedures were divided into Hartmann procedure and primary anastomosis. Open vs minimally invasive groups were defined by intention to treat. MAIN OUTCOME MEASURES: Outcomes measures included length of stay and overall morbidity and mortality. RESULTS: Of 130,616 patients, 7105 met inclusion criteria (4486 Hartmann procedure and 2619 primary anastomosis). A total of 1989 open Hartmann procedure cases were matched to 663 minimally invasive cases. The minimally invasive group underwent longer operations and had lower rates of respiratory failure. There were no differences in overall complications, mortality, length of stay, or home discharge. In the primary anastomosis group, 1027 cases were matched 1:1. The minimally invasive approach was associated with longer operative times, but reduced wound dehiscence, sepsis, bleeding, overall complications, and length of stay. No difference was detected in anastomotic leak, mortality, reoperation, or readmission rates. LIMITATIONS: Limitations include retrospective nature, data loss, nonuniformity, selection bias, and coding errors. CONCLUSIONS: Emergent minimally invasive primary anastomosis results in a shorter length of stay and decreased 30-day morbidity in comparison with open primary anastomosis for perforated diverticulitis. Emergent open and minimally invasive Hartmann procedures for perforated diverticulitis have comparable outcomes, perhaps because of a 40% conversion rate.

ABORDAJE ABIERTO VERSUS MNIMAMENTE INVASIVO PARA COLECTOMA DE EMERGENCIA EN DIVERTICULITIS PERFORADA: ANTECEDENTES:Tradicionalmente, la diverticulitis perforada se ha tratado con un abordaje abierto, con un procedimiento de Hartmann o una colectomía con anastomosis primaria. La cirugía mínimamente invasiva se asocia con ventajas posoperatorias en el escenario electivo y puede mostrar beneficio en el escenario emergente.OBJETIVO:El objetivo de este estudio fue comparar los resultados posoperatorios del abordaje abierto versus el mínimamente invasivo para la diverticulitis perforada emergente.DISEÑO:Ésta fue una revisión retrospectiva de la base de datos de colectomía dirigida del Programa Nacional de Mejoramiento de la Calidad Quirúrgica del Colegio Americano de Cirujanos utilizando el pareamiento por puntaje de propensión.ESCENARIO:Las intervenciones se realizaron en los hospitales participantes en la base de datos nacional.PACIENTES:Se incluyeron pacientes que fueron sometidos a colectomía emergente de 2012 a 2017. Los procedimientos se dividieron en procedimiento de Hartmann y anastomosis primaria. Los grupos abierto versus mínimamente invasivo se definieron por intención de tratar.PRINCIPALES MEDIDAS DE RESULTADO:Las medidas de resultado incluyeron la duración de la estancia, la morbilidad general y la mortalidad.RESULTADOS:De 130,616 pacientes, 7,105 cumplieron los criterios de inclusión (4,486 procedimiento de Hartmann y 2,619 anastomosis primaria). 1,989 casos abiertos de procedimientos de Hartmann se emparejaron con 663 casos mínimamente invasivos. El grupo mínimamente invasivo se sometió a operaciones más prolongadas y tuvo tasas más bajas de insuficiencia respiratoria. No hubo diferencias en las complicaciones generales, la mortalidad, la duración de la estancia o el alta domiciliaria. En el grupo de anastomosis primaria, 1,027 casos se emparejaron 1: 1. El abordaje mínimamente invasivo se asoció con tiempos quirúrgicos más prolongados, pero también con tasas reducidas de dehiscencia de herida, sepsis, sangrado, complicaciones generales y la duración de la estancia. No se detectaron diferencias en las tasas de fuga anastomótica, mortalidad, reintervención o reingreso.LIMITACIONES:Las limitaciones incluyen la naturaleza retrospectiva, pérdida de datos, falta de uniformidad, sesgo de selección y errores de codificación.CONCLUSIONES:La anastomosis primaria mínimamente invasiva emergente resulta en una estancia más corta y una disminución de la morbilidad a los 30 días en comparación con la anastomosis primaria abierta para la diverticulitis perforada. El procedimiento de Hartmann abierto y mínimamente invasivo de emergencia para la diverticulitis perforada tiene resultados comparables, quizás debido a una tasa de conversión del 40%.

Evaluation of a Minimally Invasive Bipolar Coagulation System for the Treatment of Grade I and II Internal Hemorrhoids.

BACKGROUND: Hemorrhoids are common and affect mainly the young and middle-aged populations. Current guidelines recommend treating grade I and II hemorrhoids with office-based procedures. These therapies usually require multiple applications. Hemorrhoid energy therapy treats the hemorrhoids at 1 treatment session. OBJECTIVE: The purpose of this study was to evaluate the safety and efficacy of hemorrhoid energy therapy. DESIGN: This was a prospective pilot study evaluating patients with symptomatic grade I and II internal hemorrhoids. SETTINGS: The study was conducted at a tertiary academic center. PATIENTS: Patients over the age of 18 years with chronic, symptomatic grade I and II internal hemorrhoids who failed 2 weeks of conservative therapy were enrolled between July 2015 and January 2019. Exclusion criteria included patients with grade III or IV internal hemorrhoids, external hemorrhoids, nonhemorrhoidal GI bleeding, active proctitis, and IBD. INTERVENTIONS: Hemorrhoid energy therapy was administered in clinic, and 2 postprocedure visits were completed. A pretreatment hemorrhoid symptom score was obtained from each patient. A visual analog score was assessed posttreatment. MAIN OUTCOME MEASURES: The primary end point was to evaluate the effect of hemorrhoid energy therapy on hemorrhoid symptoms and its safety. The secondary end point was evaluation of postprocedural pain. RESULTS: A total of 35 patients were enrolled. The mean duration of hemorrhoid symptoms was 3.3 ± 6.4 years, and rectal bleeding and hemorrhoidal prolapse were the most common symptoms. After the procedure, patient hemorrhoid symptom scores decreased from mean 5.5 to 1.4. The mean immediate postprocedural visual analog score was 2.4 ± 2.1 and decreased to <1.0 after 14 days. LIMITATIONS: The limitations include lack of comparative groups, single-center design, and small cohort of patients. CONCLUSIONS: The application of hemorrhoid energy therapy in the treatment of grade I and II internal hemorrhoids is safe and results in reduction of symptoms, low rate of short-term complications, and minimal pain.

International Consensus Definition of Low Anterior Resection Syndrome.

BACKGROUND: Low anterior resection syndrome is pragmatically defined as disordered bowel function after rectal resection leading to a detriment in quality of life. This broad characterization does not allow for precise estimates of prevalence. The low anterior resection syndrome score was designed as a simple tool for clinical evaluation of low anterior resection syndrome. Although the low anterior resection syndrome score has good clinical utility, it may not capture all important aspects that patients may experience. OBJECTIVE: The aim of this collaboration was to develop an international consensus definition of low anterior resection syndrome that encompasses all aspects of the condition and is informed by all stakeholders. DESIGN: This international patient-provider initiative used an online Delphi survey, regional patient consultation meetings, and an international consensus meeting. PARTICIPANTS: Three expert groups participated: patients, surgeons, and other health professionals from 5 regions (Australasia, Denmark, Spain, Great Britain and Ireland, and North America) and in 3 languages (English, Spanish, and Danish). MAIN OUTCOME MEASURE: The primary outcome measured was the priorities for the definition of low anterior resection syndrome. RESULTS: Three hundred twenty-five participants (156 patients) registered. The response rates for successive rounds of the Delphi survey were 86%, 96%, and 99%. Eighteen priorities emerged from the Delphi survey. Patient consultation and consensus meetings refined these priorities to 8 symptoms and 8 consequences that capture essential aspects of the syndrome. LIMITATIONS: Sampling bias may have been present, in particular, in the patient panel because social media was used extensively in recruitment. There was also dominance of the surgical panel at the final consensus meeting despite attempts to mitigate this. CONCLUSIONS: This is the first definition of low anterior resection syndrome developed with direct input from a large international patient panel. The involvement of patients in all phases has ensured that the definition presented encompasses the vital aspects of the patient experience of low anterior resection syndrome. The novel separation of symptoms and consequences may enable greater sensitivity to detect changes in low anterior resection syndrome over time and with intervention.

Long-term Experience of Magnetic Anal Sphincter Augmentation in Patients With Fecal Incontinence.

BACKGROUND: Magnetic anal sphincter augmentation is a novel technique for the treatment of patients with fecal incontinence. OBJECTIVE: The current study reports the long-term effectiveness and safety of this new treatment modality. DESIGN: This was a prospective multicenter pilot study. SETTINGS: The study was performed at 4 clinical sites in Europe and the United States. PATIENTS: The cohort included patients with severe fecal incontinence for ≥6 months who had previously failed conservative therapy and were implanted with a magnetic anal sphincter device between 2008 and 2011. MAIN OUTCOME MEASURES: Adverse events, symptom severity, quality of life, and bowel diary data were collected. RESULTS: A total of 35 patients (34 women) underwent magnetic anal sphincter augmentation. The median length of follow-up was 5.0 years (range, 0-5.6 years), with 23 patients completing assessment at 5 years. Eight patients underwent a subsequent operation (7 device explantations) because of device failure or complications, 7 of which occurred in the first year. Therapeutic success rates, with patients who underwent device explantation or stoma creation counted as treatment failures, were 63% at year 1, 66% at year 3 and 53% at year 5. In patients who retained their device, the number of incontinent episodes per week and Cleveland Clinic incontinence scores significantly decreased from baseline, and there were significant improvements in all 4 scales of the Fecal Incontinence Quality of Life instrument. There were 30 adverse events reported in 20 patients, most commonly defecatory dysfunction (20%), pain (14%), erosion (11%), and infection (11%). LIMITATIONS: This study does not allow for comparison between surgical treatments and involves a limited number of patients. CONCLUSIONS: Magnetic anal sphincter augmentation provided excellent outcomes in patients who retained a functioning device at long-term follow-up. Protocols to reduce early complications will be important to improve overall results.

Sphincter-Sparing Anal Fistula Repair: Are We Getting Better?

BACKGROUND: Sphincter-sparing repairs are commonly used to treat anal fistulas with significant muscle involvement. OBJECTIVE: The current study evaluates the trends and efficacy of sphincter-sparing repairs and determines risk factors for fistula recurrence. DESIGN AND SETTINGS: A retrospective review was performed at 3 university-affiliated teaching hospitals. PATIENTS: All 462 patients with cryptoglandular anal fistulas who underwent 573 sphincter-sparing repairs between 2005 and 2015 were included. Patients with Crohn's disease were excluded. MAIN OUTCOME MEASURES: The primary outcome was the rate of fistula healing defined as cessation of drainage with closure of the external opening. Risk factors for nonhealing were also analyzed. RESULTS: Five hundred three sphincter-sparing repairs were analyzed, whereas 70 were lost to follow-up. Two hundred twenty sphincter-sparing repairs (44%) resulted in healing, 283 (56%) resulted in nonhealing with a median follow-up of 9 (range, 1-125) months. The median time to fistula recurrence was 3 (range, 0-75) months with 79% and 91% of recurrences noted within 6 and 12 months. Patients treated with a dermal advancement flap, rectal advancement flap, or ligation of the intersphincteric tract procedure were less likely to have a recurrence than patients treated with a fistula plug or fibrin glue (p < 0.001). Over time, there was a significantly increased use of the ligation of the intersphincteric tract procedure (p < 0.001) and a significantly decreased use of fistula plugs and fibrin glue (p < 0.001); healing rates improved accordingly. There were no significant differences in healing rates with respect to patient demographics, comorbidities, or fistula characteristics. LIMITATIONS: This study was limited by its retrospective design. CONCLUSIONS: Healing rates following sphincter-sparing repairs of cryptoglandular anal fistulas are modest, but have improved over time with the use of better surgical techniques. In this study, ligation of the intersphincteric fistula tract and flaps were superior to fistula plugs and fibrin glue; the former procedures are therefore favored.

Bio-Thiersch as an Adjunct to Perineal Proctectomy Reduces Rates of Recurrent Rectal Prolapse.

BACKGROUND: The rates of recurrent prolapse after perineal proctectomy vary widely in the literature, with incidences ranging between 0% and 50%. The Thiersch procedure, first described in 1891 for the treatment of rectal prolapse, involves encircling the anus with a foreign material with the goal of confining the prolapsing rectum above the anus. The Bio-Thiersch procedure uses biological mesh for anal encirclement and can be used as an adjunct to perineal proctectomy for rectal prolapse to reduce recurrence. OBJECTIVE: The aim of this study was to evaluate the Bio-Thiersch procedure as an adjunct to perineal proctectomy and its impact on recurrence compared with perineal proctectomy alone. DESIGN: A retrospective review of consecutive patients undergoing perineal proctectomy with and without Bio-Thiersch was performed. SETTINGS: Procedures took place in the Division of Colon and Rectal Surgery at a tertiary academic teaching hospital. PATIENTS: Patients who had undergone perineal proctectomy and those who received perineal proctectomy with Bio-Thiersch were evaluated and compared. INTERVENTIONS: All of the patients with rectal prolapse received perineal proctectomy with levatorplasty, and a proportion of those patients had a Bio-Thiersch placed as an adjunct. MAIN OUTCOME MEASURES: The incidence of recurrent rectal prolapse after perineal proctectomy alone or perineal proctectomy with Bio-Thiersch was documented. RESULTS: Sixty-two patients underwent perineal proctectomy (8 had a previous prolapse procedure), and 25 patients underwent perineal proctectomy with Bio-Thiersch (12 had a previous prolapse procedure). Patients who received perineal proctectomy with Bio-Thiersch had a lower rate of recurrent rectal prolapse (p < 0.05) despite a higher proportion of them having had a previous prolapse procedure (p < 0.01). Perineal proctectomy with Bio-Thiersch had a lower recurrence over time versus perineal proctectomy alone (p < 0.05). LIMITATIONS: This study was limited by nature of being a retrospective review. CONCLUSIONS: Bio-Thiersch as an adjunct to perineal proctectomy may reduce the risk for recurrent rectal prolapse and can be particularly effective in patients with a history of previous failed prolapse procedures.

Pathogenesis and persistence of cryptoglandular anal fistula: a systematic review.

Anal fistulas continue to be a problem for patients and surgeons alike despite scientific advances. While patient and anatomical characteristics are important to surgeons who are evaluating patients with anal fistulas, their development and persistence likely involves a multifaceted interaction of histological, microbiological, and molecular factors. Histological studies have shown that anal fistulas are variably epithelialized and are surrounded by dense collagen tissue with pockets of inflammatory cells. Yet, it remains unknown if or how histological differences impact fistula healing. The presence of a perianal abscess that contains gut flora commonly leads to the development of anal fistula. This implies a microbiological component, but bacteria are infrequently found in chronic fistulas. Recent work has shown an increased expression of proinflammatory cytokines and epithelial to mesenchymal cell transition in both cryptoglandular and Crohn's perianal fistulas. This suggests that molecular mechanisms may also play a role in both fistula development and persistence. The aim of this study was to examine the histological, microbiological, molecular, and host factors that contribute to the development and persistence of anal fistulas.

A posterior anal sling for fecal incontinence: results of a 152-patient prospective multicenter study.

BACKGROUND: The transobturator posterior anal sling (TOPAS) system is a posterior anal sling that is a minimally invasive, self-fixating polypropylene mesh intended to treat fecal incontinence (FI) in women who have failed conservative therapy. OBJECTIVE: We are reporting 1-year outcome in a prospective, multicenter study under investigational device exemption, evaluating this new treatment modality. STUDY DESIGN: A total of 152 women were implanted with the TOPAS system at 14 centers in the United States. FI was assessed preoperatively and at the 12-month follow up with a 14-day bowel diary, Cleveland Clinic Incontinence Scores, and FI Quality of Life questionnaires. Treatment success was defined as reduction in number of FI episodes of ≥50% compared to baseline. Missing bowel diary data were considered treatment failures. The Wilcoxon signed rank test was used to compare changes observed at 12 months vs baseline. RESULTS: Mean age was 59.6 years old (SD 9.7). The mean duration of FI was 110 mo (range 8-712) months. Mean length of the implant procedure was 33.4 (SD 11.6) minutes. Mean EBL was 12.9 (SD 10.5) mL. Average follow-up was 24.9 months. At 12 months, 69.1% of patients met the criteria for treatment success, and 19% of subjects reported complete continence. FI episodes/wk decreased from a median of 9.0 (range 2-40) at baseline to 2.5 (range 0-40) (P < .001). FI days decreased from a median of 5.0 (range 1.5-7) at baseline to 2.0 (range 0-7) (P < .001) over a 7-day period. FI associated with urgency decreased from a median at baseline of 2.0 (range 0-26) to 0 (range 0-14.5) (P < .001). The mean Cleveland Clinic Incontinence Scores decreased from 13.9 at baseline to 9.6 at 12 months (P < .001). FI Quality of Life scores for all 4 domains improved significantly from baseline to 12 months (P < .001). A total of 66 subjects experienced 104 procedure- and/or device-related adverse events (AEs). Most AEs were short in duration and 97% were managed without therapy or with nonsurgical interventions. No treatment-related deaths, erosions, extrusions, or device revisions were reported. The most common AE categories were pelvic pain (n = 47) and infection (n = 26). Those subjects experiencing pelvic pain had a mean pain score (0-10 scale, 0 = no pain) during the 12-month follow-up of 1.2 (SD 2.4). CONCLUSION: The TOPAS system provides significant improvements in FI symptoms and quality of life with an acceptable AE profile and may therefore be a viable minimally invasive treatment option for FI in women.

Adenocarcinoma of the rectum in patients under age 40 is increasing: impact of signet-ring cell histology.

BACKGROUND: Overall, the incidence of colorectal cancer appears to be stable or diminishing. However, based on our practice pattern, we observed that the incidence of rectal cancer in patients under 40 is increasing and may be associated with a prominence of signet-ring cell histology. OBJECTIVE: The aim of this study was to verify the rising trend in rectal cancer in patients under 40 and describe the histology prominent in that cohort. DESIGN: This is a retrospective cohort study. SETTING AND PATIENTS: We performed a retrospective cohort study of all patients diagnosed with rectal adenocarcinoma from 1980 to 2010 using the Surveillance, Epidemiology, and End Results cancer registry. MAIN OUTCOME MEASURES: Rectal cancer incidence, histology, and associated staging characteristics were the primary outcomes measured. RESULTS: Although the incidence of rectal cancer for all ages remained stable from 1980 to 2010, we observed an annual percent change of +3.6% in the incidence of rectal cancer in patients under 40. The prevalence of signet cell histology in patients under 40 was significantly greater than in patients over 40 (3% vs 0.87%, p < 0.01). A multivariate regression analysis revealed an adjusted odds ratio of 3.6 (95% CI, 2.6-5.1) for signet cell histology in rectal adenocarcinoma under age 40. Signet cell histology was also significantly associated with a more advanced stage at presentation, poorly differentiated tumor grade, and worse prognosis compared with mucinous and nonmucinous rectal adenocarcinoma. LIMITATIONS: The study was limited by its retrospective nature and the information available in the Surveillance, Epidemiology, and End Results database. CONCLUSIONS: Despite a stable incidence of rectal cancer for all ages, the incidence in patients under 40 has quadrupled since 1980, and cancers in this group are 3.6 times more likely to have signet cell histology. Given the worse outcomes associated with signet cell histology, these data highlight a need for thorough evaluation of young patients with rectal symptoms.

Clinical outcomes of perineal proctectomy among patients of advanced age.

BACKGROUND: Rectal prolapse occurs primarily in older patients who often have significant comorbidities. With the aging population, increasing numbers of elderly patients are presenting with rectal prolapse. The perineal approach is preferred for these patients because it involves less perioperative risk than an abdominal procedure, but the outcomes of this procedure in elderly patients are unknown. OBJECTIVE: The aim of this study was to examine whether clinical outcomes after perineal proctectomy are similar among elderly patients versus patients of younger age. DESIGN: This study was a retrospective review. SETTING: This study was conducted in mixed academic and private practice; the operations were performed at 16 hospitals. PATIENTS: Patients who had perineal proctectomy for rectal prolapse from 1994 to 2012 were grouped according to age: <70 (group A), 70 to 79 (group B), 80 to 89 (group C), and ≥90 years (group D). INTERVENTIONS: Perineal proctectomy with or without concurrent levatorplasty was performed. MAIN OUTCOME MEASURES: The primary outcomes measured were postoperative complications, recurrence, and survival after perineal proctectomy. RESULTS: Four hundred patients underwent 518 perineal proctectomies: group A, N = 113; group B, N = 113; group C, N = 208; and group D, N = 84. The immediate and late complication rates were 5.6% and 3.5% and did not vary by age. Recurrence was 22.6% and was significantly different between groups, with the lowest recurrence in group D, 14.3% (p = 0.007). Reoperation after recurrence was less likely in group D. The main type of reoperation was perineal proctectomy (41.5%), but, for group D, recurrence was usually managed nonoperatively (58.3%). Median survival after operation was more than 4 years in the advanced age group. LIMITATIONS: Retrospective data, which did not allow analysis of patients with rectal prolapse who did not undergo surgery, were used in this study. CONCLUSIONS: When selected appropriately, patients 90 years of age or older have outcomes similar to younger patients; therefore, age alone should not be a contraindication to surgery. In addition, elderly patients have a median survival of more than 4 years after surgery, so the operative risk can be worth the benefit accrued.

Outcomes after transanal endoscopic microsurgery with intraperitoneal anastomosis.

BACKGROUND: Transanal endoscopic microsurgery has gained increasing popularity as a treatment alternative for early stage rectal neoplasms. With continued advances in technique and experience, more proximal rectal tumors are being surgically managed by using transanal endoscopic microsurgery with an intraperitoneal anastomosis. OBJECTIVE: The purpose of this study was to review the outcomes of patients who have undergone intraperitoneal anastomosis with the use of the transanal endoscopic microsurgery technique. DESIGN: A prospective, single-surgeon database documented 445 consecutive patients undergoing transanal endoscopic microsurgery from October 1, 1996 through January 1, 2012. We retrospectively reviewed information from all patients who underwent transanal endoscopic microsurgery with an intraperitoneal anastomosis in this prospective database. SETTINGS: All procedures took place in an inpatient hospital setting. PATIENTS: All patients satisfied workup criteria to undergo surgery for rectal neoplasm. INTERVENTIONS: All patients underwent transanal endoscopic microsurgery for rectal neoplasm. MAIN OUTCOME MEASURES: Size and pathology of lesion, length of procedure, hospital stay, estimated blood loss, margin status, and complications were the outcomes measured. RESULTS: Twenty-eight patients who underwent transanal endoscopic microsurgery had definitively documented intraperitoneal entry and anastomosis. Median follow-up was 12 months (range, 0.5-111 months). There were no operative mortalities. Procedure-related complications included urinary retention (11%), fever (11%), and fecal seepage (4%). Four patients (14%) had positive margins on final pathology. One patient (3%) required abdominal exploration for an anastomotic leak but did not require diversion. LIMITATIONS: Although this study analyzes prospectively collected data, it is nonetheless a retrospective analysis that can introduce bias. Because this is a single-center study with a relatively homogenous population, the results may not be generalizable. Our sample size may also be underpowered to detect clinically significant outcomes. CONCLUSIONS: Transanal endoscopic microsurgery with intraperitoneal anastomosis can be safely performed without fecal diversion by experienced surgeons.

Pelvic Necrosis with Formation of a Pelvic "Cloaca" and Necrotizing Soft Tissue Infection After Radiation for Anal Squamous Cell Carcinoma.

BACKGROUND Anal squamous cell carcinoma (SCC) is a rare cancer commonly treated with the Nigro protocol, which combines chemotherapy and radiation. Patients who received radiation therapy prior to modern advances, such as computer-based tumor targeting, volumetric planning, and intensity-modulated radiation therapy, experience more acute and chronic adverse effects. Though exceedingly rare, radiation necrosis is of particular concern, as it can result in significant morbidity and mortality, including complex pelvic fistula formation and predisposition to potentially life-threatening necrotizing soft-tissue infections. CASE REPORT Here, we present a case of a 66-year-old woman with a prior history of anal SCC stage T3N×M0 who was treated with the Nigro protocol. Her treatment course was complicated by radiation proctitis, necessitating fecal diversion and ureteral strictures, requiring frequent stent exchanges. She presented 18 years after her cancer treatment, with widespread necrosis of her pelvic organs and surrounding soft tissue, resulting in formation of a large pelvic "cloaca", with a superimposed necrotizing soft-tissue infection. She was successfully treated by expedited resuscitation, septic source control, using multiple extensive debridements, and complete urinary diversion, utilizing a multidisciplinary team. CONCLUSIONS This case highlights the importance of monitoring patients for signs of radiation toxicity, particularly in patients who received radiation prior to the latest technological advancements, as they are at increased risk of developing severe, late adverse effects decades after treatment. When these complications are recognized, early and aggressive intervention is required to spare the patient significant morbidity and mortality.
