The efficacy of porcine dermal collagen to treat complex anal fistulae: results of a multicenter cohort

Introduction: The management of complex anal fistulae remains a topical surgical problem. The choice and success of surgical management are based on the balance between healing and continence. Although porcine dermal collagen (Permacol Collagen Paste [PCP]- Covidien plc, Gosport, Hampshire, UK) represents a new generation of non-solid biomaterials, its results in anal fistulae are mixed. Methods: A multicenter observational retrospective analysis of consecutive patients with cryptoglandular anal fistula treated in four colorectal surgery units was performed between 2015 and 2020. Clinical cure of the fistula was the main outcome measure. Adverse events and alterations in anal continence were secondary outcomes. Results: The study included 119 patients (87 males, 71.1%), with a mean age of 53 years (IR 44-65). Most patients had complex (80.6%) and recurrent (91.6%) fistulae. With the first PCP treatment, the overall cure rate was 41.2% (49 patients) and 45.4% with the second treatment (5 out of 17 patients). The mean follow-up period was 17 months (IR 5-25). Healing was not affected by the location and type of fistula, the existence or not of a cavity, the number of tracts, or the administration of prophylactic antibiotics. After the PCP treatment, no patient in the series had worsening of continence. Morbidity affected 22.7% of the patients (27), with postoperative abscesses being the most frequent adverse event. There were no statistical differences between the four hospitals studied. Conclusions: Permacol collagen paste is a safe and easily reproducible therapy for complicated anal fistulae that has moderate efficacy. The overall success rate is slightly over 40%, with no detriment to fecal continence. (AU)

Care burden and outcome of the surgical management of ulcerative colitis: A retrospective analysis of the last 20 years in a tertiary hospital in Spain / Carga asistencial y resultados del tratamiento quirúrgico de la colitis ulcerativa: un análisis retrospectivo de los últimos 20 años en un hospital terciario de España

Aim: To analyze the surgical burden of UC care in the last two decades, analyzing the characteristics of the patients, surgical indications along with the short and long-term results. Method: Single-center retrospective cohort analysis of UC patients undergoing abdominal and anorectal surgery between January 2000 and December 2020. The care burden, clinical data and results were analyzed according to distribution by decades. Results: 128 patients, 37% female, underwent 376 surgical interventions (296 intestinal procedures and 80 anorectal). Mean follow-up for the cohort was 106±64 months. Timing from diagnosis to first surgery was under 5 years in 53.3%. In the second decade of the study there were fewer operated patients (73 vs. 48) as well as the total number of interventions per patient (2.7 vs. 2.0). The proportion between elective and urgent surgery was reversed in the second decade, observing an increase in laparoscopic surgery (70% vs. 8%) together with a decrease in major postoperative morbidity (Clavien-Dindo≥IIIa) (20% vs 8.4%). 80 patients underwent a restorative proctocolectomy, with a failure of 5% at 1 year but 23.7% in the long term. 37 patients required anorectal surgery, of which 26 (71%) were serial interventions, most due to septic complications of the pouches. Conclusions: The number of colectomies and interventions per patient decreased in the last decade, while there were improvements in morbidity and surgical approach. The need for sequential surgeries and long-term active instrumental surveillance for possible functional deterioration constitutes a significant clinical burden. (AU)

Objetivo: Analizar la carga quirúrgica asistencial por CU en 20 años, analizando las características de los pacientes, indicaciones quirúrgicas y resultados a corto y largo plazo. Método: Análisis retrospectivo unicéntrico de pacientes intervenidos de enero del 2000 a diciembre del 2020. La carga asistencial, los datos clínicos y los resultados se analizaron según distribución por décadas. Resultados: Ciento veintiocho pacientes, 37% mujeres, con 376 intervenciones quirúrgicas (296 procedimientos intestinales y 80 anorrectales). El seguimiento medio de la cohorte fue de 106±64 meses. El lapso entre el diagnóstico y la primera cirugía fue <5 años en el 53,3%. En la segunda década del estudio hubo menos pacientes operados (73 frente a 48) y un menor número de intervenciones por paciente (2,7 frente a 2,0). La proporción entre cirugía electiva y urgente se revirtió en la segunda década, observándose un aumento de la cirugía laparoscópica (70% vs. 8%) junto con una disminución de la morbilidad postoperatoria mayor (Clavien-Dindo≥IIIa) (20% vs 8.4%). Se realizó una proctocolectomía restauradora a 80 pacientes, con un fracaso al año del 5% pero del 23,7% a largo plazo. Treinta y siete pacientes requirieron cirugía anorrectal, de los cuales 26 (71%) fueron intervenciones seriadas, la mayoría por complicaciones sépticas de los reservorios. Conclusiones: El número de colectomías y de intervenciones por paciente disminuyó en la última década, a la vez que hubo mejorías en la morbilidad y el abordaje quirúrgico. La necesidad de cirugías secuenciales y de una vigilancia instrumental activa a largo plazo por el posible deterioro funcional constituye una importante carga clínica. (AU)

Gender differences in stage at diagnosis and preoperative radiotherapy in patients with rectal cancer.

BACKGROUND: Few studies have examined gender differences in the clinical management of rectal cancer. We examine differences in stage at diagnosis and preoperative radiotherapy in rectal cancer patients. METHODS: A prospective cohort study was conducted in 22 hospitals in Spain including 770 patients undergoing surgery for rectal cancer. Study outcomes were disseminated disease at diagnosis and receiving preoperative radiotherapy. Age, comorbidity, referral from a screening program, diagnostic delay, distance from the anal verge, and tumor depth were considered as factors that might explain gender differences in these outcomes. RESULTS: Women were more likely to be diagnosed with disseminated disease among those referred from screening (odds ratio, confidence interval 95% (OR, CI = 7.2, 0.9-55.8) and among those with a diagnostic delay greater than 3 months (OR, CI = 5.1, 1.2-21.6). Women were less likely to receive preoperative radiotherapy if they were younger than 65 years of age (OR, CI = 0.6, 0.3-1.0) and if their tumors were cT3 or cT4 (OR, CI = 0.5, 0.4-0.7). CONCLUSIONS: The gender-specific sensitivity of rectal cancer screening tests, gender differences in referrals and clinical reasons for not prescribing preoperative radiotherapy in women should be further examined. If these gender differences are not clinically justifiable, their elimination might enhance survival.

Late anastomotic leakages in rectal surgery: a wake-up call about their impact on long-term results.

OBJECTIVE: To assess the impact of the incidence of late anastomotic dehiscences, defined as those occurring after the 60th post-operative day, in the final results of rectal cancer treatment. METHODS: A retrospective analysis was performed reviewing all anastomotic leakages (AL) recorded in a prospective rectal cancer database, from November 2006 to December 2015. RESULTS: The analysis included 395 (71.5%) colo-rectal anastomosis performed in 552 patients undergoing rectal cancer surgery. Overall 32 (8.1%). AL were identified: 25 (78%) early and 7 (22%) late. Late AL compared to early AL were significantly associated with: higher ASA score (p = 0.021), higher CLS score (p = 0.005), lower rectal tumours (p = 0.014), neo-adjuvant radio-chemotherapy (p = 0.028), presence of ileostomy (p = 0.013), early hospital discharge (p = 0.048) and with the need for definitive stoma creation (p = 0.003). CONCLUSIONS: Late AL can represent up to 22% of all AL; with significant long-term implications such as an increase of the requirement of definitive stoma or chronic pelvic sepsis. This findings could modify the long-term outcomes in rectal cancer published. In our experience, the late AL do not represent a distinct clinical process compared to early forms, with exception of the chronological criteria.

OBJETIVO: Valorar el impacto de la incidencia de dehiscencias anastomóticas tardías, definidas como las aparecidas después del día 60 del posoperatorio, en los resultados finales del tratamiento del cáncer de recto. MÉTODO: Estudio retrospectivo de todas las dehiscencias anastomóticas recogidas a largo plazo en un registro prospectivo de cáncer de recto entre noviembre de 2006 y diciembre de 2015. RESULTADOS: Se realizaron 395 anastomosis colorrectales en 552 pacientes con cáncer de recto (71.5%) y se diagnosticaron 32 dehiscencias anastomóticas (8.1%): 25 precoces (78%) y 7 tardías (22%). Las tardías se diferenciaron de las precoces por presentarse en pacientes con mayor puntuación ASA (p = 0.021), mayor puntuación predictiva CLS (p = 0.005), tumores más bajos (p = 0.014), neoadyuvancia (p = 0.028), ileostomía (p = 0.013), menos tiempo de estancia posoperatoria (p = 0.048) y mayor necesidad de estomas definitivos (p = 0.003). CONCLUSIONES: Las dehiscencias anastomóticas tardías pueden suponer el 22% de las dehiscencias totales y se acompañan de un aumento de estomas definitivos y de sepsis pélvica crónica que podrían empeorar los estándares publicados en cáncer de recto. En nuestra experiencia no son diferentes de las formas precoces salvo en su cronología.
