¿Ha disminuido la colectomía por crisis de colitis ulcerosa?

Background: Treatment for moderate-severe active ulcerative colitis (UC) includes steroids, biologic therapy and total colectomy. Aim: To describe the features of patients with moderate to severe active UC, their hospital evolution and need for colectomy. Material and Methods: Non-concurrent cohort study of all patients admitted to our institution with a diagnosis of moderate or severe UC crisis between January 2008 and May 2019. Truelove Witts (TW) criteria were used to categorize disease severity. Twelve-month colectomy-free survival was estimated with Kaplan-Meier survival analysis. Results: One hundred-twenty patients aged 16 to 89 (median 35) years had 160 admissions for acute moderate to severe UC. Median admission per patient was 1 (1-3), and median hospital stay was six days (1-49). Cytomegalovirus and Clostridioides difficile were found in 17.5 and 14.2% of crises, respectively. Corticosteroids were used in all crises and biologic therapy in 6.9% of them. Emergency or elective colectomies were performed in 18.3 and 6.7% of patients, respectively. The need for emergency total colectomy decreased from 24.6 to 7.8% (Risk ratio 3.16, p < 0.01) between de first and second half of the study period. Kaplan-Meier analysis for long term colectomy-free survival in both periods confirmed this decrease (p < 0.01). Conclusions: Medical treatment for moderate to severe UC crises had a 86.3% success and a small percentage required emergency total colectomy. Emergency surgery decreased in the last decade.

Diagnóstico y manejo de colitis ulcerosa grave: una mirada actualizada / Management of severe ulcerative colitis: an up-to-date

Ulcerative Colitis (UC) is a chronic inflammatory disease involving the colon, with alternating periods of remission and activity. Exacerbations can be severe and associated with complications and mortality. Diagnosis of severe UC is based on clinical, biochemical and endoscopic variables. Patients with severe UC must be hospitalized. First line therapy is the use of intravenous corticoids which achieve clinical remission in most patients. However, 25% of patients will be refractory to corticoids, situation that should be evaluated at the third day of therapy. In patients without response, cytomegalovirus infection must be quickly ruled out to escalate to second line therapy with biological drugs or cyclosporine. Total colectomy must not be delayed if there is no response to second line therapy, if there is a contraindication for second line therapies or there are complications such as: megacolon, perforation or massive bleeding. An active management with quick escalation on therapy allows to decrease the prolonged exposure to corticoids, reduce colectomy rates and its perioperative complications.

Insuficiencia intestinal secundaria a síndrome de intestino corto: resultados de un programa multidisciplinario de rehabilitación intestinal / Intestinal failure due to short bowel syndrome: impact of a multidisciplinary intestinal rehabilitation program

Background: In patients suffering intestinal failure due to short bowel, the goal of an Intestinal Rehabilitation Program is to optimize and tailor all aspects of clinical management, and eventually, wean patients off lifelong parenteral nutrition. Aim: To report the results of our program in patients suffering intestinal failure. Patients and Methods: A registry of all patients referred to the Intestinal Failure unit between January 2009 and December 2015 was constructed. Initial work up included prior intestinal surgery, blood tests, endoscopic and imaging studies. Also demographic data, medical and surgical management as well as clinical follow-up, were registered. Results: Data from 14 consecutive patients aged 26 to 84 years (13 women) was reviewed. Mean length of remnant small bowel was 100 cm and they were on parenteral nutrition for a median of eight months. Seven of 14 patients had short bowel secondary to mesenteric vascular events (embolism/thrombosis). Medical management and autologous reconstruction of the bowel included jejuno-colic anastomosis in six, enterorraphies in three, entero-rectal anastomosis in two, lengthening procedures in two, ileo-colic anastomosis in one and reversal Roux-Y gastric bypass in one. Thirteen of 14 patients were weaned off parenteral nutrition. Conclusions: Our Multidisciplinary Intestinal Rehabilitation Program, allowed weaning most of the studied patients off parenteral nutrition.

Resultados inmediatos y alejados del reservorio ileal con anastomosis reservorio-anal practicado en forma simultánea o diferida con la proctocolectomía en pacientes portadores de colitis ulcerosa / Ileal pouch-anal anastomosis performed simultaneously or delayed with the proctocolectomy: short and long-term results in patients with ulcerative colitis

Objetivo: Analizar las diferencias en los resultados quirúrgicos entre 2 grupos en colitis ulcerosa: proctocolectomía, reservorio ileal y anastomosis reservorio-anal (RIARA), simultáneo con la proctocolectomía (grupo 1) o diferido (grupo 2). Material y método: Estudio retrospectivo en 126 pacientes sometidos a RIARA. En todos los pacientes se confeccionó un RIARA en «J¼, excepto en 4 que se hizo en «S¼. Todos fueron protegidos con ileostomía. Complicaciones Clavien-Dindo II-V fueron registradas. Resultados: Pacientes con una mediana de edad de 37 años (12-61), 72 eran de género femenino (57%). Se practicó proctocolectomía y RIARA en 24 pacientes (19%) y proctectomía y RIARA en 102 (81%). Se observaron complicaciones postoperatorias en 19 pacientes (13%). Infección de la herida y sepsis pelviana, en 4% respectivamente, fueron las más frecuentes. Tres pacientes fueron reintervenidos: 2 por hemoperitoneo y uno por necrosis isquémica del reservorio. No hubo mortalidad postoperatoria. No se observó diferencia significativa en la morbilidad postoperatoria entre los grupos. Se observaron complicaciones a largo plazo en 48 pacientes (38%): obstrucción intestinal en 18 pacientes (14%), fístula reservorio-vaginal (FRV) en 9 (12,5%), y reservoritis crónica en 8 (6,9%) fueron las más frecuentes. Al comparar los 2 grupos, se observó mayor frecuencia de FRV en el grupo 1 (p = 0,02). Conclusión: En este estudio no se demostró diferencia en la morbilidad postoperatoria entre el grupo 1 y 2. En los resultados alejados hubo mayor frecuencia significativa de FRV en el grupo 1.

Aim: To compare the surgical results of both groups: Simultaneous with the proctocolectomy (SRP) (group 1) or delayed after colectomy (DRP) (group 2). Material and methods: Retrospective study on 126 patients submitted to RP. All patients had a J-pouch, except 4 S. All of them protected with a loop ileostomy. The median time between colectomy and IPAA was 5 months (4-6 range). Clavien-Dindo II-V complications were registered. Results: 126 patients had IPAA. Age median 37 years (12-61 range); 72 (57%) women. SRP in 24 (19%) and DRP was performed in 102 (81%). Postoperative complications were recorded in 19 patients (13%). Wound infection and pelvic sepsis were observed in 4% each. Three patients needed early reoperation: two for hemoperitoneum and one for ischemic necrosis of the pouch. There was no post-operative mortality. No significant difference in 30 days postoperative complication rate was found between SRP and DRP. On long-term follow-up: Intestinal obstruction in 18 patients (14%), pouch-vaginal fistula (PVF) in 9 (12.5%) and chronic pouchitis in 8 (6.9%) were the most common complications. PVF was significantly more frequent on group 1. Conclusion: In this series, no significant difference was found in the early surgical results between group 1 and 2. In the long term, PVF was significantly more common in group 1.

Ileostomía en asa derivativa y lavado colónico intraoperatorio como alternativa de tratamiento en un caso de colitis grave por Clostridium difficile / Treatment of a severe Clostridium difficile infection with colonic lavages. Report of one case

A loop ileostomy with intraoperative anterograde colonic lavage has been described as an alternative to colectomy in the management of cases of Clostridium difficile infection refractory to medical treatment. We report a 69 years old diabetic women admitted with a septic shock. An abdominal CAT scan showed a pan-colitis that seemed to be infectious. A polymerase chain reaction was positive for Clostridium Difficile. Due to the failure to improve after full medical treatment, a derivative loop ileostomy and intra-operatory colonic lavage were performed, leaving a Foley catheter in the proximal colon. In the postoperative period, anterograde colonic instillations of Vancomycin flushes through the catheter were performed every 6 hours. Forty eight hours after surgery, the patient improved. A colonoscopy prior to discharge showed resolution of the pseudomembranous colitis.

Un índice neutrófilo/linfocito elevado se asocia a peor pronóstico en cancer de colon etapa II resecado / An elevated neutrophil/lymphocyte ratio is associated with poor prognosis in stage II resected colon cancer

Background: The neutrophil/lymphocyte ratio is an effective marker of inflammation ana can have prognostic value in surgical patients. Aim: To evaluate the effect of an increased neutrophil/lymphocyte ratio (NLR) on perioperative complications ana overall ana disease-free survival in patients undergoing elective resection for stage II colon cancer. Material and Methods: Data was obtained from clinical charts, preoperative blood results and hospital records of all patients undergoing an elective curative resection for colon cancer, between 2000 and 2007. Preoperative NLR was calculated. Follow-up was obtained from a prospectively maintained colorectal cancer database, clinical records and questionnaires. Uni and multivariable analysis were performed to identify associations, and survival analysis was performed using Kaplan-Meier curves. Results: One hundred twenty two patients with a mean age of69years (52% males), were evaluated. Median follow-up was 73 months, and overall survival for 1 and 5years was 95% and 68%, respectively. On a multivariable analysis after adjusting for age, sex, tumor depth invasion, use of adjuvant therapies and American Society of Anesthesiology preoperative risk score, an NLR > 5 was associated with an increased perioperative complication rate (odds ratio: 3,06, p = 0,033). Kaplan-Meier survival analysis showed a worse overall and disease-free survival for patients with NLR greater than five. Conclusions: A preoperative NLR of five or more is associated with greater perioperative morbidity and worse oncological outcomes in patients undergoing resection for elective stage II colon cancer.

Evaluación de la mucosectomía cincunferencial (PPH) en el tratamiento de la patología hemorroidal: experiencia U. C / Evaluation of circunferential mucosectomy (PPH) in the treatment of hemorrhoidal pathology: U. C. experience

En el tratamiento quirúrgico de la patología hemorroidal se ha reportado el uso de engrapadora circular asociada con menor dolor en el postoperatorio y una temprana incorporación a la actividad normal. El objetivo de este trabajo fue evaluar los resultados de la mucosectomía circunferencial con engrapadora en pacientes con prolapso hemorroidal y/o mucoso en nuestro centro. Material y Métodos. Se realizó un estudio prospectivo de pacientes con patología hemorroidal sintomática, entre agosto del 2001 y julio del 2004. Los pacientes fueron sometidos a mucosectomía circunferencial con engrapadora. Todos los pacientes recibieron cuidados pre-operatorios estándares y regímenes de analgesia con anti-inflamatorios no esteroidales (AINES) en el post-operatorio. En la primera semana del postoperatorio los pacientes completaron encuestas de escalas análogas de dolor (1-10). Durante el seguimiento los pacientes fueron evaluados con un cuestionario por teléfono y contacto con el médico tratante. Resultados. En total 34 pacientes fueron evaluados. El promedio de dolor en el primer día postoperatorio fue escaso (promedio 2,8) y hacia el cuarto día referían mínimo dolor (promedio 1,3). La mediana de seguimiento fue de 12 meses. Las complicaciones en el postoperatorio inmediato fueron: Tres pacientes presentaron hemorragia aguda y uno presentó retención urinaria. Durante el seguimiento 5 pacientes presentaron recidiva de síntomas hemorroidales (2 debieron ser reoperados). Además, 2 presentaron dolor anal limitado y 2 dolor anal crónico por corchete de la engrapadora circular. Conclusión. En esta serie la mucosectomía circunferencial con engrapadora demostró ser la técnica asociada con escaso dolor en el post-operatorio. Sin embargo, no está exenta de complicaciones y recidiva que deben considerarse al ofrecer este procedimiento a nuestros pacientes.
