Patrones de recurrencia/persistencia en la operación de LIFT para la fístula anal de origen criptoglandular. Estudio observacional a largo plazo / Patterns of recurrence/persistence of criptoglandular anal fistula after the LIFT procedure. Long-term observacional study

Objetivo: Valorar la recidiva/persistencia de la fístula anal compleja tras cirugía de tipo LIFT y analizar los patrones de recurrencia/persistencia. Pacientes y método: Estudio observacional de pacientes afectos de fístula anal transesfinteriana o supraesfinteriana tratada mediante la técnica LIFT durante el periodo diciembre de 2008-abril de 2016. Se analizan las características clínicas, la técnica quirúrgica y su resultado. Se define la curación clínica y se emplean pruebas de imagen en casos de duda. Se utiliza la escala Wexner para el estudio de la continencia. El tiempo mínimo de seguimiento ha sido de un año. Resultados: Un total de 55 pacientes fueron intervenidos: 53 con fístula transesfinteriana y 2 supraesfinteriana. Se produjeron 16 fracasos (29%): 7 fístulas completas (originales), 6 interesfinterianas (downstage) y 3 trayecto residuales externos. La localización posterior y la complejidad del trayecto fueron factores de riesgo de recurrencia/persistencia. La presencia de un sedal previo no mejoró los resultados. Ningún caso presentó alteración de la continencia (Wexner 0). Del total, 9 pacientes presentaron complicaciones leves (9%): 4 heridas interesfinterianas con cierre tardío y una trombosis hemorroidal externa. La mediana del cierre del orificio externo fue de 5 semanas (RI: 2-6). Las heridas interesfinterianas curaron en 4-8 semanas. Conclusión: La técnica de LIFT en nuestra experiencia ha resultado una operación segura, reproductible, con escasa morbilidad, nula repercusión en la continencia y un porcentaje de éxito superior al 70%. Se definen 3 tipos de recurrencia: la fístula interesfinteriana, la fístula original (trans- o supraesfinteriana) y el trayecto externo residual. Considerando los tipos de recurrencia, tan solo el 12,7% de los pacientes han necesitado cirugías más complejas para solucionar esta entidad. El resto de las recurrencias/persistencias se han solucionado con gestos simples (fistulotomía en la formas interesfinterianas y legrados en los trayectos residuales) (AU)

Objective: To study the recurrence/persistence rate of complex cripotoglandular anal fistula after the LIFT procedure and analyse the patterns of recurrence/persistence. Patients and methods: Observational study of patients with transe-sphincteric or supra-sphincteric anal fistula treated using the LIFT procedure from December 2008 to April 2016. Variables studied included clinical characteristics, surgical technique and results. Clinical cure was defined and imaging studies were used in doubtful cases. Wexner's score was used for continence evaluation. The minimum follow-up time was one year. Results A total of 55 patients were operated on: 53 with a trans-sphincteric fistula and 2 supra-sphincteric. There were 16 failures (29%): 7 complete fistulas (original), 6 intersphincteric (downstage), and 3 external residual tracts. A posterior location and complexity of the tract were risk factors for recurrence/persistence. The presence of a seton did not improve results. No case presented decrease of continence (Wexner 0). Nine patients presented minor complications (9%): 4 intersphincteric wounds with delayed closure and one external hemorrhoidal thrombosis. The median time to closure of the external opening was 5 weeks (IR 2-6). Intersphincteric wounds closed in 4-8 weeks. Conclusion: In our experience, the LIFT technique is a safe and reproducible procedure with low morbidity, no repercussion on continence and a success rate over 70%. There are 3 types of recurrence: the intersphincteric fistula, the original fistulatula (trans- or supra-sphincteric) and the residual external tract. Considering the types of recurrence, only 12,7% of patients need more complex surgery to solve their pathology. The rest of the recurrences/persistence were solved by simple procedures (fistulotomy in intersphincteric forms and legrado in residual tracts) (AU)

Rehabilitación multimodal y cirugía intestinal por enfermedad de Crohn: Factores asociados a estancia hospitalaria prolongada / «Fast track» and intestinal surgery for Crohn’s disease: Factors associated with prolonged hospital stay

OBJETIVO: Los objetivos del trabajo fueron determinar los factores asociados a una estancia postoperatoria (EP) prolongada en pacientes con resección intestinal por enfermedad de Crohn (EC) con un protocolo de rehabilitación multimodal (RM). MÉTODOS: Se incluyó a los pacientes intervenidos entre enero de 2013 y diciembre de 2015 por EC. Para la RM se siguió un protocolo de 8 puntos. Las variables estudiadas fueron: edad, sexo, EP, ASA, localización y patrón de la EC, presencia de enfermedad perianal, índice de Harvey-Bradshaw, resección previa, tipo de cirugía actual (mínimamente invasiva vs. laparotomía) y Clavien-Dindo. Se realizó un estudio inferencial para identificar los factores asociados a una EP > de 6 días y un modelo logístico multivariante. RESULTADOS: Se intervino a 52 pacientes. La EP mediana fue de 8 días (RI: 5-11). En el análisis univariante, la localización (L1 vs. L2-3), el patrón (B2 vs. B3), la existencia de enfermedad perianal, la cirugía previa, el tipo de cirugía realizada, el Harvey-Bradshaw y el grado de Clavien-Dindo se asociaron todos ellos con una EP inferior o superior a 6 días. El modelo parsimonioso que mejor ajusta para predecir una EP >6 días es el que contiene la variable Harvey-Bradshaw (OR: 6,49; IC 95%: 1,46-28,8) y el tipo de cirugía efectuado (OR: 0,23; IC 95%: 0,05-0,95). CONCLUSIONES: La estancia prolongada tras cirugía resectiva por EC se relaciona más con el tipo o gravedad de la enfermedad y de cirugía realizada que con otras características del paciente. Los pacientes con EC requieren una buena coordinación entre prehabilitación, RM y transferencia de cuidados postoperatorios

OBJECTIVE: The aim of this study was to determine factors associated with a prolonged postoperative stay (PS) in patients operated on with bowel resection for Crohn's disease (CD) included in an enhanced recovery program (ERP). METHODS: We included patients operated on for CD between January 2013 and December 2015. ERP was organized following an 8-point protocol. Variables studied were: age, sex, PS, ASA, location and type of CD, presence of perianal disease, Harvey-Bradshaw index, previous resection, type of surgery (minimally invasive vs. laparotomy) and Clavien Dindo. An inferential study was performed to identify factors related with a PS > 6 days and multivariate analysis. RESULTS: A total of 52 patients were operated on. The median PS was 8 days (IR: 5-11). In the univariate analysis, location (L1 vs. L2-3), type (B2 vs. B3), presence of perianal disease, prior surgery, type of surgery performed, Harvey-Bradshaw index and Clavien-Dindo were associated with a PS > or< than 6 days. The model that best adjusts to predict a PS > 6 days contained the variable Harvey-Bradshaw (OR: 6,49; 95% CI: 1,46-28,8) and the type of surgery (OR: 0,23; 95%CI: 0,05-0,95). CONCLUSION: A prolonged postoperative stay after bowel resection for CD is more related to the type or severity of the disease and the type of surgery performed, than with other patient factors. Patients with CD need good coordination between prehabilitation, ERP and postoperative management

Incidencia y caracterización del síndrome de resección anterior de recto mediante la utilización de la escala LARS (low anterior resection score) / Incidence and characterization of the anterior resection syndrome through the use of the LARS scale (low anterior resection score)

INTRODUCCIÓN: Recientemente se ha validado una escala internacional de puntuación (LARS) que cuantifica el síndrome de resección anterior (SRA). El objetivo de este estudio es conocer la incidencia y gravedad del SRA utilizando el LARS y su relación con variables seleccionadas. MÉTODOS: A todos los pacientes con resección anterior por cáncer de recto operados entre octubre de 2007 y febrero de 2014, con intención curativa y con más de un año de funcionalidad, se les envió el cuestionario LARS. Las variables estudiadas fueron: edad, sexo, tiempo transcurrido desde la cirugía, tipo de resección, vía quirúrgica, tipo de anastomosis, realización de estoma derivativo, complicación postoperatoria y régimen de radioterapia. RESULTADOS: De 195 pacientes, 136 (70%) respondieron (132 adecuadamente). El 47% de los pacientes presentaba un LARS mayor y el 34% no desarrolló SRA cuantificable. Se relacionó un LARS mayor con peor calidad de vida (p = 0,002). En el análisis univariante, la escisión mesorrectal total (ETM), la radioterapia larga y el estoma derivativo se asociaron a un LARS mayor, y la utilización de un reservorio, a uno menor. En el análisis multivariante solo el tipo de resección (p < 0,001) y la utilización de reservorio (p = 0,002) fueron factores individuales relacionados con el LARS. CONCLUSIONES: La mitad de los pacientes operados presentaron un LARS mayor y solo un tercio no presentó un SRA cuantificable. La percepción global de la calidad de vida fue significativamente peor en los pacientes con LARS mayor. La ausencia de recto (ETM) y la forma de reconstrucción anastomótica fueron los principales factores asociados a la puntuación LARS

INTRODUCTION: Recently a score (LARS) has been internationally validates that quantifies the anterior resection syndrome (ARS). The objective of this study is to know the incidence and severity of the ARS using LARS and its correlation with selected variables or risk factors. METHODS: All operated patients with anterior resection for rectal cancer between October 2007 and February 2014, with curative intention and at least one year of functionality, were sent a LARS questionnaire. The variables studied were: Age sex, time elapsed since surgery, type of surgical approach, type of anastomosis, derivative ileostomy, postoperative pelvic complication, and radiotherapy regimen. RESULTS: Out of 195 patients, 136 (70%) responded, and 132 responded properly. A total of 47% of the patients presented «severe» LARS and 34% did not develop quantifiable ARS. Quality of life was worse in the highest LARS scores (P=.002). In the univariate analysis, total mesorectal excision, long radiotherapy regimen and derivative stoma were associated to «severe» LARS and the use of a reservoir was associated with minor LARS. In multivariate analysis only the type of resection (P<.001) and the use of a reservoir (P=.002) were individual factors related to LARS. CONCLUSIONS: Half of the operated patients presented high LARS score and only a third did not provide a quantifiable ARS. The overall perception of quality of life was significantly worse in patients with more severe LARS. The absence of the rectum (total mesorectal excision) and the type of anastomosis were the main factors associated with the LARS score

Exenteración pélvica total en el tratamiento de las neoplasias avanzadas, primarias o recurrentes, de vísceras pélvicas / Total pelvic exenteration for the treatment of advanced primary or recurrent pelvic neoplasia

INTRODUCCIÓN: La resección completa con márgenes libres en los tumores viscerales pélvicos localmente avanzados, primarios o recurrentes, requiere ocasionalmente de una exenteración pélvica total (EPT). MÉTODOS: Revisamos los resultados obtenidos con la EPT en 34 pacientes consecutivos operados entre junio de 2006 y diciembre de 2013. RESULTADOS: La mediana de edad fue de 62 (40-82) años; 24 (70%) eran varones. El origen tumoral más frecuente fue el avanzado y primitivo de recto (TAPR), con 19 casos (55,9%) y el tipo de exenteración, la supraelevadora (61,8%). Se logró una resección R0 en 24 (70,6%) pacientes y en 16 (85%) de los TAPR. Quince (79%) pacientes con TAPR tenían pT4, y 4 (20%) pN+. La continuidad intestinal y urinaria se realizó con 2 estomas en 17 casos (50%), Bricker y anastomosis colorrectal en 11 (32,3%) y colostomía húmeda double barreled en 6 (17,6%). No hubo mortalidad postoperatoria; 23 (67,5%) pacientes tuvieron complicaciones y 5 (14,6%) requirieron una reoperación en el postoperatorio. La mediana de seguimiento fue de 23 (13-45) meses. La supervivencia global (SG) y libre de enfermedad (SLE) a los 2 años fueron del 67% y 58% respectivamente, y la mediana de SG y SLE fue de 59 meses (IC 95%: 26 a 110) y de 39 meses (IC 95%: 14 a 64), respectivamente. La SLE de las R0 fue significativamente mejor (p = 0,003) que las R1. CONCLUSIONES: La EPT es un procedimiento potencialmente curativo para las neoplasias viscerales avanzadas de la pelvis, con una morbimortalidad similar a otras cirugías exeréticas mayores

INTRODUCTION: Complete resection with clear margins in locally advanced pelvic visceral tumors, primary or recurrent, occasionally requires total pelvic exenteration (TPE). METHODS: We reviewed the results of EFA in 34 consecutive patients operated on between June 2006 and December 2013.ResultsMedian age was 62 (40-82) years; 24 (70%) were male. The tumor origin most frequent was advanced primary rectal tumor (APRT), with 19 cases (55.9%) and most common type of exenteration was supraelevator (61.8%). R0 resection was achieved in 24 (70.6%) patients and in 16 (85%) of the APRT. Fifteen (79%) patients had pT4 APRT, and 4 (20%) pN +. Reconstruction of the bowel and bladder was performed with two stomas in 17 cases (50%), colorectal anastomosis and Bricker in 11 (32.3%) and wet double barreled colostomy in 6 (17.6%). There was no postoperative mortality; 23 (67,5%) patients had complications, and 5 (14.6%) required a postoperative reoperation to solve them. Median follow-up was 23 (13-45) months. Overall survival (OS) and disease free survival (DFS) at 2 years were 67% and 58% respectively, and the median OS and DFS was 59 months (95% CI 26-110) and 39 months (95% CI 14-64), respectively. The DFS of R0 was significantly better (p = 0.003) than R1. CONCLUSIONS: TPE is a potentially curative procedure for advanced pelvic visceral malignancies with similar morbi-mortality than other extended excisional surgery

Delorme's Procedure for Complete Rectal Prolapse: A Study of Recurrence Patterns in the Long Term.

Introduction. The objective of this study was to determine the recurrence rate and associated risk factors of full-thickness rectal prolapse in the long term after Delorme's procedure. Patients and Methods. The study involved adult patients with rectal prolapse treated with Delorme's surgery between 2000 and 2012 and followed up prospectively in an outpatient unit. We assessed epidemiological data, Wexner constipation and incontinence score, recurrence patterns, and risk factors. Data were analyzed by univariate and multivariate studies and follow-up was performed according to Kaplan-Meier technique. The primary outcome was recurrence. Results. A total of 42 patients, where 71.4% (n = 30) were women, with a median age of 76 years (IQR 66 to 86), underwent Delorme's surgery. The median follow-up was 85 months (IQR 28 to 132). There was no mortality, and morbidity was 9.5%. Recurrence occurred in five patients (12%) within 14 months after surgery. Actuarial recurrence at five years was 9.9%. According to the univariate analysis, constipation and concomitant pelvic floor repair were the only factors found to be associated with recurrence. Multivariate analysis showed no statistically significant differences among variables studied. Kaplan-Meier estimate revealed that constipation was associated with a higher risk of recurrence (log-rank test, p = 0.006). Conclusions. Delorme's procedure is a safe technique with an actuarial recurrence at five years of 9.9%. The outcomes obtained in this study support the performance of concomitant postanal repair and levatorplasty to reduce recurrences. Also, severe constipation is associated with a higher recurrence rate.

Preventing complications in colorectal anastomosis: results of a randomized controlled trial using bioabsorbable staple line reinforcement for circular stapler.

BACKGROUND: Anastomotic complications, including leaks, stenoses, and bleeding, cause considerable mortality and morbidity after colorectal surgery. OBJETIVE: The purpose of this work was to evaluate the effectiveness of bioabsorbable staple line reinforcement in reducing colorectal anastomotic complications. DESIGN: This was a prospective randomized clinical study. SETTINGS: This study was conducted at a university hospital within a specialized colorectal unit. PATIENTS: Patients undergoing left colon resection for a benign or malignant condition were eligible. A total of 302 patients participated, including 154 control subjects and 148 with reinforcement. INTERVENTION: Patients were prospectively randomly assigned to reinforcement of circular stapled anastomosis with a bioabsorbable device versus stapled circular anastomosis without reinforcement. MAIN OUTCOME MEASURES: The primary end point was the rate of pooled incidences of anastomotic complications (leakage, bleeding, or stenosis). Secondary outcomes were the rate of reoperations and the length of hospital stay. RESULTS: Baseline characteristics were similar between both groups. Intention-to-treat analysis revealed that there were no significant differences in the pooled incidences of anastomotic complications (p = 0.821). Regarding individual complications, we did not observe statistical differences between groups, including leakage (6.6% vs 4.8%; p = 0.518), hemorrhage (1.4% vs 1.3%; p = 0.431), or stenosis (2.9% vs 6.8%; p = 0.128). Again, no significant differences were observed in length of stay (7 days; p = 0.242) or rate of reoperation (7.3% vs 9.6%; p = 0.490). A patient (0.3%) in the control group died. LIMITATIONS: Sample size calculation was performed including all 3 of the complications, which may render it underpowered to detect differences regarding a specific complication. Anastomoses located within 5 cm from the anal verge were excluded from the study. CONCLUSIONS: The results obtained show that bioabsorbable staple line reinforcement in a colorectal anastomosis >5 cm from the anal verge does not reduce the rate of pooled anastomotic complications (ie, leaks, bleeding, or stenosis).

Prognosis and follow-up of 135 patients with ischemic colitis over a five-year period.

AIM: To study the prognosis (recurrence and mortality) of patients with ischemic colitis (IC). METHODS: This study was conducted in four Spanish hospitals, participants in the Ischemic Colitis in Spain study We analyzed prospectively 135 consecutive patients who met criteria for definitive or probable IC according to Brandt criteria, and follow up these patients during the next five years, retrospectively. Long-term results (recurrence and mortality) were evaluated retrospectively after a median interval of 62 mo (range 54-75 mo). RESULTS: Estimated IC recurrence rates were 2.9%, 5.1%, 8.1% and 9.7% at years 1, 2, 3 and 5 years, respectively. Five-year survival was 69% (93 of 135) and 24% (10 of 42 patients) died for causes related to the IC. Among these 10 patients, 8 died in their first episode at hospital (4 had gangrenous colitis and 4 fulminant colitis) and 2 due to recurrence. CONCLUSION: The five-year recurrence rate of IC was low. On the other hand, mortality during follow-up was high and was not associated with ischemic colitis.

Metástasis pancreáticas por carcinoma renal. Nuestra casuística y revisión de la literatura / Pancreatic metastases due to renal carcinoma. Our cases and a literature review

Analizar los casos de metástasis pancreáticas por carcinoma renal intervenidos en nuestro hospital entre los años 2000 y 2011.Material y métodos Estudio retrospectivo donde se recogen diferentes variables de 8 pacientes con metástasis pancreáticas por carcinoma renal intervenidos. Comparación de nuestros datos con los de la literatura. Resultados La enfermedad metastásica del páncreas por carcinoma renal en nuestra serie ha sido de 1,2%. Todas las metástasis han sido metacrónicas. La afectación por sexo ha sido igual. El tiempo medio entre la resección del tumor renal y el diagnóstico de las metástasis ha sido de 12,42 años (rango: 1,62-30,13 años). La actitud terapéutica ante las lesiones pancreáticas ha sido quirúrgica en todos los casos. Hasta la fecha, 7 pacientes continúan vivos. Conclusión La enfermedad metastásica del páncreas por carcinoma renal es poco frecuente (1-2,8%). El intervalo entre la resección primaria y las metástasis puede ser bastante largo. Siempre debe sospecharse metástasis pancreática en los pacientes que presenten masa pancreática e historia de carcinoma renal. Se recomienda un tratamiento quirúrgico agresivo en casos seleccionados. La cirugía en estos casos mejora la supervivencia y la calidad de vida (AU)

Objective: To analyse the cases of pancreatic metastases due to renal carcinoma operated on in our hospital between the years 2000 and 2011.Material and methods: A retrospective study using the variables of 8 patients who were subjected to surgery of pancreatic metastases due to renal carcinoma, and a comparison of our data with those from the literature. Results: The incidence of metastatic disease of the pancreas due to renal carcinoma in our series was 1.2%. All the metastases were metachronous, with both sexes being affected equally. The mean time between resection of the renal tumour and the diagnosis of the metastasis was 12.42 years (range: 1.62-30.13 years). The therapeutic approach to the pancreatic lesions was surgical in all cases. Seven patients are currently still alive. Conclusion: Metastatic disease of the pancreas due to renal carcinoma is uncommon(1%-2.8%). The interval between the primary resection and the metastasis can be quite long. Pancreatic metastasis must always be suspected in patients who present with a pancreatic mass and a history of renal carcinoma. Aggressive surgical treatment is recommended in selected cases. The surgery in these cases improves survival and the quality of life (AU)

Proctitis actínica, hemorrágica crónica y refractaria. Experiencia con formaldehído al 4% / Radiation proctitis and chronic and refractory bleeding. Experience with 4% formaldehyde

Introducción: La hemorragia es una complicación frecuente de la proctitis secundaria a radioterapia de tumores pélvicos. Entre el 5 y el 10% pueden ocasionar cuadros graves y rebeldes a los tratamientos tópicos y endoscópicos. Se presenta la experiencia con la aplicación de formaldehído al 4%.Pacientes y método Estudio retrospectivo y descriptivo de una cohorte de pacientes con proctitis actínica grave ingresados en el Hospital Universitario Donostia entre enero de 2003 y septiembre de 2009. Todos los pacientes fueron diagnosticados por colonoscopia e ingresados por su severidad para tratamiento. Se empleó formaldehído al 4% tanto con la técnica de la gasa como mediante enemas, en los casos rebeldes al tratamiento tópico y endoscópico con argón. La técnica se realizó en quirófano con anestesia regional. Se realizaron controles clínicos y endoscópicos. Resultados Veinticinco varones (73,5%) y 9 mujeres (26,5%), con una edad media de 69 años (32–80) presentaron rectorragia por proctitis actínica y precisaron ingreso. En 6 pacientes (28,5%) fracasaron todos los tratamientos y se empleó formaldehído al 4%. La respuesta a la hemorragia fue completa en los 6 pacientes, 3 casos con una sesión y otros 3 con 2 sesiones. En 4 pacientes se empleó la técnica de la gasa y en otros 2 (por presencia de estenosis) enema de formaldehído al 4%. En 2 pacientes apareció dolor como complicación principal (33,3). La mediana de seguimiento ha sido de 60 meses (rango intercuartílico 26 a 67 meses). Conclusiones El formaldehído al 4% en la hemorragia por proctitis actínica es una técnica eficaz, fácilmente reproducible y con poca morbilidad (AU)

Introduction: Bleeding is a common complication of proctitis secondary to radiotherapy of pelvic tumours. Between 5 and 10% may become severe and refractory to topical and endoscopic treatment. Experience with the application of 4% formaldehyde is presented. Patients and method: A retrospective and descriptive study was performed on a patient cohort with severe radiation proctitis admitted to the Hospital Universitario Donostia between January 2003 and September 2009. All patients were diagnosed by colonoscopy and admitted due to the severity of their treatment. Both 4% formaldehyde and the gauze technique were used, as well as using enemas, in cases refractory to topical and endoscopic treatment with argon. The technique was performed in theatre with regional anaesthetic. Clinical and endoscopic follow up was carried out. Results: The study included 25 males (73.5%) and 9 women (26.5%), with a mean age of69 years (32–80) who had rectal bleeding due to radiation proctitis and required admission. All treatments failed in 6 (28.5%) patients, and 4% formaldehyde was used, with a complete response to the bleeding in all 6 patients, with 3 cases requiring one session, and the 3 others2 sessions. The gauze technique was used in 4 patients and another 2 were given a formaldehyde enema due to the presence of stenosis. Pain appeared as the main complication in 2 (33.3%) patients. The median follow up was 60 months (interquartile range 26 to67 months).Conclusions: The use of 4% formaldehyde in bleeding due to radiation proctitis is an effective, easy to reproduce technique, with a low morbidity (AU)

[Pancreatic metastases due to renal carcinoma. Our cases and a literature review]. / Metástasis pancreáticas por carcinoma renal. Nuestra casuística y revisión de la literatura.

OBJECTIVE: To analyse the cases of pancreatic metastases due to renal carcinoma operated on in our hospital between the years 2000 and 2011. MATERIAL AND METHODS: A retrospective study using the variables of 8 patients who were subjected to surgery of pancreatic metastases due to renal carcinoma, and a comparison of our data with those from the literature. RESULTS: The incidence of metastatic disease of the pancreas due to renal carcinoma in our series was 1.2%. All the metastases were metachronous, with both sexes being affected equally. The mean time between resection of the renal tumour and the diagnosis of the metastasis was 12.42 years (range: 1.62-30.13 years). The therapeutic approach to the pancreatic lesions was surgical in all cases. Seven patients are currently still alive. CONCLUSION: Metastatic disease of the pancreas due to renal carcinoma is uncommon (1%-2.8%). The interval between the primary resection and the metastasis can be quite long. Pancreatic metastasis must always be suspected in patients who present with a pancreatic mass and a history of renal carcinoma. Aggressive surgical treatment is recommended in selected cases. The surgery in these cases improves survival and the quality of life.

[Radiation proctitis and chronic and refractory bleeding. Experience with 4% formaldehyde]. / Proctitis actínica, hemorrágica crónica y refractaria. Experiencia con formaldehído al 4%

INTRODUCTION: Bleeding is a common complication of proctitis secondary to radiotherapy of pelvic tumours. Between 5 and 10% may become severe and refractory to topical and endoscopic treatment. Experience with the application of 4% formaldehyde is presented. PATIENTS AND METHOD: A retrospective and descriptive study was performed on a patient cohort with severe radiation proctitis admitted to the Hospital Universitario Donostia between January 2003 and September 2009. All patients were diagnosed by colonoscopy and admitted due to the severity of their treatment. Both 4% formaldehyde and the gauze technique were used, as well as using enemas, in cases refractory to topical and endoscopic treatment with argon. The technique was performed in theatre with regional anaesthetic. Clinical and endoscopic follow up was carried out. RESULTS: The study included 25 males (73.5%) and 9 women (26.5%), with a mean age of 69 years (32-80) who had rectal bleeding due to radiation proctitis and required admission. All treatments failed in 6 (28.5%) patients, and 4% formaldehyde was used, with a complete response to the bleeding in all 6 patients, with 3 cases requiring one session, and the 3 others 2 sessions. The gauze technique was used in 4 patients and another 2 were given a formaldehyde enema due to the presence of stenosis. Pain appeared as the main complication in 2 (33.3%) patients. The median follow up was 60 months (interquartile range 26 to 67 months). CONCLUSIONS: The use of 4% formaldehyde in bleeding due to radiation proctitis is an effective, easy to reproduce technique, with a low morbidity.

Ligaduras múltiples verticales: un nuevo enfoque en el tratamiento de la enfermedad hemorroidal grado III. Estudio de seguridad y eficacia / Multiple vertical ligatures: A new approach to the treatment of haemorrhoidal disease grade III. Safety and efficacy study

Introducción: La ligadura elástica es el método ambulatorio más empleado en la enfermedad hemorroidal, con excelentes resultados en el control de la hemorragia. Sin embargo, las recurrencias en el prolapso oscilan del 15 al 40%. Proponemos un nuevo método de aplicación de ligaduras elásticas. Pacientes Diecisiete pacientes con hemorroides iii fueron elegidos para las ligaduras verticales (LV). La primera banda se colocó de 3 a 4cm a de la línea pectínea y 1 o 2 más en la raíz del grupo hemorroidal. Treinta y cuatro pacientes seleccionados aleatoriamente fueron empleados como grupo control. Se recogieron los datos demográficos, número de bandas y sesiones, escala de dolor, complicaciones y resultados. Los controles se realizaron a la semana, a la 3a semana, a los 3 meses y al año. Resultados Doce varones y 5 mujeres, con una mediana de edad de 46 años fueron tratados con LV. La mediana de seguimiento fue de 10 meses (de 8 a 19). Una mediana de 3 sesiones y 7 bandas fueron empleadas. Seis pacientes presentaron dolor moderado que requirió tratamiento analgésico. Ningún paciente precisó tratamiento urgente por dolor o hemorragia. Hubo respuesta completa al sangrado en 15 pacientes (88,2%) y al prolapso en 14 (82,2%). Dos pacientes requirieron hemorroidectomía por fracaso del tratamiento. Al final del año las medidas del efecto terapéutico fueron: NNT de 4 (IC 95%, de 2 a 22), para el prolapso y NNT de 4 (IC 95%, 2 a 15) para el sangrado. Conclusiones Las ligaduras elásticas verticales pueden representar una nueva alternativa para el tratamiento de hemorroides grado iii, mejorando los controles de sangrado y prolapso (AU)

INTRODUCTION: The elastic ligature is the most used method for the out-patient treatment of haemorrhoids, with excellent results in control of bleeding. However, the recurrences in prolapse vary between 15 and 40%. We propose a new method for applying the elastic ligatures. PATIENTS: A total of 17 patients with grade iii haemorrhoids were chosen for the vertical ligatures (VL). The first elastic band was placed 3 to 4 cm from the pectineal line and 1 or 2 more in the root of the haemorrhoid group. Another 34 randomly selected patients were used as a control group. Data collected included, demographic details, number of bands and sessions, pain scale, complications and results. The patients were followed up at week one, week 3, and 3 months and one year after the intervention. RESULTS: A total of 12 males and 5 females, with a median age of 46 years, were treated with VL. The median follow-up was 10 (from 8 to 19) months. A median of 3 sessions and 7 elastic bands were used, with 6 patients having moderate pain that required analgesic treatment. None of the patients needed urgent treatment for pain or bleeding. There was a complete response to bleeding in 15 patients (88.2%) and to prolapse in 14 (82.2%). Two patients required haemorrhoidectomy due to treatment failure. The measurements of therapeutic effect after one year were: number needed to treat (NNT) of 4 (95% CI, 2 to 22), for prolapse, and NNT of 4 (95% CI, 2 a 15), for bleeding. CONCLUSIONS: Elastic ligatures could become a new treatment option for Grade iii haemorrhoids, improving control of bleeding and prolapse.

Patterns of local recurrence in rectal cancer after a multidisciplinary approach.

Improvements in surgery and the application of combined approaches to fight rectal cancer have succeeded in reducing the local recurrence (LR) rate and when there is LR it tends to appear later and less often in isolation. Moreover, a subtle change in the distribution of LRs with respect to the pelvis has been observed. In general terms, prior to total mesorectal excision the most common LRs were central types (perianastomotic and anterior) while lateral and posterior forms (presacral) have become more common since the growth in the use of combined treatments. No differences have been reported in the current pattern of LRs as a function of the type of approach used, that is, neo-adjuvant therapies (short-term or long-course radiotherapy, or chemoradiotherapy versus extended lymphadenectomy, though there is a trend towards posterior or presacral LR in patients in the Western world and lateral LR in Asia. Nevertheless, both may arise from the same mechanism. Moreover, as well as the mode of treatment, the type of LR is related to the height of the initial tumor. Nowadays most LRs are related to the advanced nature of the disease. Involvement of the circumferential radial margin and spillage of residual tumor cells from lymphatic leakage in the pelvic side wall are two plausible mechanisms for the genesis of LR. The patterns of pelvic recurrence itself (pelvic subsites) also have important implications for prognosis and are related to the potential success of salvage curative approach. The re-operability for cure and prognosis are generally better for anastomotic and anterior types than for presacral and lateral recurrences. Overall survival after LR diagnosis is lower with radio or chemoradiotherapy plus optimal surgery approaches, compared to optimal surgery alone.

Recto (colpo, perineo) sacropexia ventral en el tratamiento del prolapso rectal y rectogenital / Ventral rectal sacropexy (colpo-perineal) in the treatment of rectal and rectogenital prolapse

Introducción La sacrorrectopexia ventral con malla permite la corrección del prolapso rectal minimizando la disección del recto. La colpopexia posterior corrige los prolapsos apicales y posteriores de la vagina. La combinación de ambos procedimientos permite la corrección simultánea de los prolapsos de los órganos pelvianos (POP).Objetivo Presentar los resultados de una serie de pacientes con distintos tipos de POP tratados mediante la misma técnica quirúrgica. Material y método Entre enero de 2005 y agosto de 2008 intervinimos mediante una recto(colpo)sacropexia ventral a 57 pacientes diagnosticados de alguna forma de POP, que dividimos en tres grupos: grupo A, prolapso rectal total aislado o combinado con histerocele o colpocele (11 pacientes); grupo B, rectoenterocele con invaginación rectal interna y/o periné descendente (4 pacientes), y grupo C, prolapso genital del compartimento medio-posterior (42 pacientes). Se intervino por vía laparoscópica a los 15 pacientes de los grupos A y B y a 11 del grupo C. En 41 casos se empleó una malla biológica, y en los demás, una sintética macroporosa. Resultados La media de edad de la serie era 66 (19–81) años; 55 eran mujeres y 2, varones; la mediana de seguimiento fue 25 (4–48) meses). No hubo complicaciones postoperatorias mayores. En el grupo A registramos una recurrencia del prolapso (1/11); los 7 pacientes que presentaban incontinencia mejoraron tras la intervención; no se registró ningún caso de estreñimiento de novo y 8 de los 9 pacientes de los grupos A y B, con defecación obstructiva, mejoraron. En el grupo C se detectaron 9 (21%) recurrencias de alguno de los compartimentos vaginales, pero sólo 4 (9%) requirieron reintervención. En todas las recurrencias se había utilizado una malla biológica (..) (AU)

Introduction Ventral sacral-rectopexy with mesh corrects rectal prolapse and minimises rectal dissection. Subsequent colpopexy corrects apical and posterior prolapses of the vagina. The combination of both procedures can lead to the simultaneous correction of pelvic organ prolapses (POP). Objective To present the results of a patient series with several types of POP treated using the same approach and operation. Material and method A total of 57 patients diagnosed with any type of POP were operated on between January 2005 and August 2008 using ventral rectal-colpo-sacropexy, who were grouped into three types: A, total rectal prolapse isolated or combined with a hysterocele or colpocele (11 patients); B, rectoenterocele with internal rectal invagination and/or descending perineum (4 patients); and C, middle and posterior genital compartment prolapse (42 patients). The laparoscopic approach was used in the 15 patients of groups A and B and 11 from group C. A b iological mesh was used in 41 patients and a macroporous synthetic one in the rest. Results The mean age of the patients in the series was 66 (19–81) years, with 55 females and 2 males. The median follow up was 25 (4–48) months. There were no major post-surgical complications. A recurrence of prolapse was recorded in one patient in group A (1/11); the 7 patients who suffered from incontinence improved after the surgery, no case of de novo constipation being recorded and an improvement in 8 of the 9 patients from groups A and B with obstructive defaecation. There were 9 (21%) recurrences detected in group C, but only 4 (9%) required reintervention. In all the recurrences a biological mesh had been used. Conclusions Laparoscopic ventral rectal-colpo-pexy is an effective technique to correct POP. Although safe and innocuous, the results with biological meshes did not last as long (AU)
