RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Multiple clinical trials have demonstrated the benefits of adjuvant 5-fluorouracil-based chemotherapy for patients with resectable colon cancer (CC), especially in stage III. AIM: To describe the clinical characteristics of a cohort of CC patients treated at a single university hospital in Chile since 2002, and to investigate if chemotherapy had an effect on survival rates. MATERIAL AND METHODS: Review of a tumor registry of the hospital. Medical records of patients with CC treated between 2002 and 2012 were reviewed. Death certificates from the National Identification Service were used to determine mortality. Overall survival was described using the Kaplan-Meier method. A multivariate Cox proportional hazard regression model was also used. RESULTS: A total of 370 patients were treated during the study period (202 in stage II and 168 in stage III). Adjuvant chemotherapy was administered to 22 and 70% of patients in stage II and III respectively. The median follow-up period was 4.6 years. The 5-year survival rate for stage II patients was 79% and there was no benefit observed with adjuvant chemotherapy. For stage III patients, the 5-year survival rate was 81% for patients who received adjuvant chemotherapy, compared to 56% for those who did not receive chemotherapy (hazard ratio (HR): 0.29; 95% confidence interval (CI): 0.15-0.56). The benefit of chemotherapy was found to persist after adjustment for other prognostic variables (HR: 0.47; 95% CI: 0.23-0.94). CONCLUSIONS: Patients with colon cancer in stage III who received adjuvant chemotherapy had a better overall survival.

RESUMEN

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.
