Stem Cell Therapy in Refractory Perineal Crohn's Disease: Long-term Follow-up.

AIM: To describe the long-term outcomes of adipose-mesenchymal stem cells, platelet-rich plasma, and endorectal advancement flaps in patients with Perineal Crohn's Disease. METHOD: This was a single-center, prospective, observational pilot study performed between March 2013 and December 2016. The study included adult patients diagnosed with Perianal Crohn's Disease (with complex perianal fistulas) refractory to previous surgical and/or biological treatment. Patients underwent surgical treatment in two stages. Stage 1: Fistula mapping, drainage, seton placement and lipoaspiration to obtain adipose-mesenchymal stem cells were performed. Stage 2: The setons were removed, and the fistula tract was debrided. A small endorectal advancement flap was created, with closure of the previous internal fistula opening. Then, 100-120 million adipose-mesenchymal stem cells mixed with platelet-rich plasma were injected into the internal fistula opening and fistula tract. RESULTS: The study included nine patients (seven females), with a median age of 36 years (r = 23-57). Eleven fistula tracks were treated, of which, two were pouch-vaginal fistulas. The median follow-up period was 31 months (r=21-37). At the end of the follow-up period, 10/11 (91%) fistulas were completely healed and 1/11 (9%) was partially healed. At the end of this period, there was no evidence of fistula relapse or adverse reactions in any patients. The Perianal Disease Activity Index and Inflammatory Bowel Disease Questionnaire scores significantly improved after the procedure. CONCLUSION: Combined therapy with adipose-mesenchymal stem cells, platelet-rich plasma and endorectal advancement flaps yielded good results in patients with refractory Perineal Crohn's Disease.

[Inflammatory bowel disease. Experience in 316 patients]. / Enfermedad inflamatoria intestinal a partir de una experiencia local.

BACKGROUND: The incidence and prevalence of Inflammatory Bowel Disease (IBD) has increased. AIM: To determine demographic and clinical characteristics of patients with IBD in a Chilean private hospital. PATIENTS AND METHODS: Review of a prospective registry of patients with IBD, started on 2012. It includes clinical, imaging, endoscopical and pathological information of patients. RESULTS: Data of 316 patients with IBD, aged 16 to 86 years (56% females), were analyzed. Ulcerative Colitis (UC), Crohn´s and non-classifiable IBD were diagnosed in 230, 77 and 9 patients, respectively. The disease was diagnosed in 82% of patients in the period between 2002 and 2012. There was a peak in the diagnosis of both UC and CD between 20 and 39 years of age, without gender differences. The disease switched from UC to CD in six patients. In four, there was a change in disease behavior. Thirty eight patients were treated with biological therapy. The median lapse between the diagnosis and the use of biological therapy was 1 year in patients diagnosed after 2007, compared with 5.5 years among those patients diagnosed before 2007 (p = 0.001). There was a trend towards a higher requirement of surgery until 2006. Subsequently there was a stabilization of the requirement, concomitant with the incorporation of biological therapy. CONCLUSIONS: An adequate registry of IBD patients is necessary to improve demographic and clinical characteristics. A national registry is needed to assess the epidemiological changes of IBD in Chile.

Does obesity increase early postoperative complications after laparoscopic colorectal surgery? Results from a single center.

BACKGROUND: Laparoscopic colorectal surgery (LCRS) has several advantages over open surgery, but LCRS has been associated with a higher rate of postoperative complications (POCs) among obese patients [body mass index (BMI), ≥30 kg/m(2)]. The prevalence of obesity in Chile is increasing, up to 25.1% in 2010, suggesting that a higher percentage of patients undergoing LCRS will be obese. This study compared POC rates between obese and nonobese patients undergoing LCRS. METHODS: This study included case and control patients in a prospectively maintained LCRS database who underwent LCRS between July 2007 and June 2012 at Clinica Las Condes, Santiago, Chile. Obese and nonobese (BMI <30 kg/m(2)) patients were paired by gender, age, American Society of Anesthesiologists class, preoperative diagnosis, and type of surgery. Intraoperative complications and POCs were documented up to 30 days. The severity of each POC was classified by Clavien-Dindo score. RESULTS: In this study, 449 patients who underwent LCRS during the study period were identified. The study paired 53 obese patients (mean BMI 33.1 kg/m(2)) with 53 nonobese patients (mean BMI 25.9 kg/m(2)). The median age was 55 years in the obese group and 57 years in the nonobese group, and 60% of the patients in both groups were men. The findings showed POCs in 13 obese (24.5%) and 15 nonobese (28.3%) patients (p = 0.66). Stratified by severity of POCs, the two groups were similar (p = 0.62). The two groups did not differ in terms of the median time to the first feeding (1 day each) or the hospital length of stay (4 days each). Similar percentages of patients in the two groups required reoperation (p = 0.4), intensive care unit (ICU) admission (p = 0.77), and readmission to the hospital (p = 0.65) because of POCs. CONCLUSION: The frequency of POCs after LCRS was no higher among the obese patients than among the nonobese patients.

INTRODUCCIÓN: La disinergia del piso pelviano (DPP) es una causa frecuente de estreñimiento por obstrucción defecatoria. El tratamiento de esta enfermedad esta basado en la rehabilitación pelviperineal (RPP). El objetivo de este estudio es evaluar los resultados de la RPP en pacientes con DPP. Métodos Se incluye a pacientes con DPP a quienes se les realizó RPP entre el año 2010 y el 2011. Se aplicó previamente a las sesiones y al término de ellas un cuestionario de estreñimiento (KESS) (escala de 0 a 39 puntos: a mayor puntuación mayor sintomatología). Se compararon los resultados del cuestionario KESS, de forma previa y posterior a la RPP. Análisis estadístico mediante Mann-Whitney-Wilcoxon para muestras pareadas; se consideró significativo p < 0,05. RESULTADOS: Se incluyó a 13 pacientes (11 mujeres), edad promedio: 44,3 años (r: 18-76). La puntuación promedio del KESS previa y posterior al tratamiento fue de 19,6 (DE: 5,8) y de 12,6 puntos (DE: 6,3), respectivamente (p = 0,002). La frecuencia evacuatoria, consistencia de las deposiciones, dolor abdominal y distensión abdominal no varían significativamente con el tratamiento. La necesidad del uso de enemas, laxantes o digitación, así como la evacuación no exitosa o incompleta disminuyeron en forma significativa. Asimismo, el tiempo total de evacuación (pre: 1,53 vs. post: 1; p = 0,012) y la percepción de dificultad para evacuar (pre: 2,08 vs. post: 1,07; p = 0,001) mejoraron significativamente. CONCLUSIONES: La RPP en pacientes con DPP mejora significativamente los síntomas de la obstrucción defecatoria, principalmente con relación a la asistencia mecánica y percepción de dificultad defecatoria

INTRODUCTION: Pelvic floor dyssynergia (PPD) is a common cause of outlet obstruction constipation. Treatment for this condition is based on pelvi-perineal re-education (PPR). The aim of this study was to evaluate the results of PPR on patients with PPD. METHOD: Patients with the diagnosis of PPD were included. The study was conducted between 2010 and 2011. PPR was performed by specialized kinesiologists. Prior and after treatment a constipation questionnaire was performed (KESS) (scale from 0 to 39 points, a higher score is associated with more symptom severity). KESS score before and after PPR were compared. Mann-Whitney-Wilcoxon rank sum test for paired samples was used for statistical analysis, p value < 0,05 was considered as significant. RESULTS: Thirteen patients were included (11 women), mean age 44.3 years old (r: 18-76). Mean total KESS score prior and after PPR were 19.6 (SD: 5.8) and 12.6 (DS: 63), respectively (P = .002). Frequency of bowel movements, stool consistency, abdominal pain and abdominal bloating did not present statistically significant changes before and after treatment. Use of laxatives, enemas and/or digitations, as well as unsuccessful evacuation, feelings of incomplete evacuation improved significantly. Total evacuation time (before 1.53 vs after 1; P = .012) and difficult evacuation causing painful efforts (before 2.08 vs after 1.07; P = .001) also decreased significantly. CONCLUSION: PPR in patients with PPD, significantly improves the symptoms of obstructive constipation, mainly with respect to mechanical assistance and difficult evacuation

Background: Currently there is a consensus in oncological safety for laparoscopic surgery for colon cancer; however, in rectal cancer long term outcomes are still a subject of debate. The aim is to analyze long term survival in patients who underwent laparoscopic surgery for rectal cancer. Material and Methods: From the prospective database of laparoscopic colorectal surgery, we selected patients operated on between October 2000 and December 2009. Patients with hereditary colorectal cancer were excluded. Follow-up data was obtained by medical records and national vital records. Survival was analyzed using the Kaplan-Meier method. Results: In this period, 60 patients were operated on for rectal cancer. Two died in the early postoperative period and were excluded from the analysis; therefore, 58 patients were included in follow-up. Forty-one percent were female and mean age was 60±11.6 years old. Tumors were localized in the upper, mid and lower rectum in 28%, 28% and 44%, respectively. Surgeries performed were abdominoperineal resection, ultra-low intersphincteric resection, ultralow anterior resection and low anterior resection in 8%, 28%, 5% and 59% of patients, respectively. Fifty percent received neoadjuvant treatment. After postoperative staging 4% were classified as stage 0,17% as stage I, 28% as stage II, 28% as stage III, and 13% as stage IV. At a mean 42.6 month follow-up (r: 17-103 months) estimated overall 5-year survival was 85%. When analyzed according to stage, estimated overall 5-year survival was 100% for stages 0 and I, 88% for stage II, 74% for stage III, and 57% for stage IV. Conclusion: Long term survival in patients undergoing laparoscopic surgery for rectal cancer is satisfactory and is within the values reported by international centers.

Stapled hemorrhoidectomy: initial experience of a Latin American group.

The purpose of the present study was to determine the value of circular hemorrhoidectomy (procedure for prolapse and hemorrhoids [PPH]) on the basis of data collected prospectively during the initial experience of a group of Latin American surgeons. Between 2000 and 2001, PPH was performed using a circular stapler in 177 patients who had third- and fourth-degree hemorrhoidal disease. The average age of the patients was 47.7 years (range 26 to 85 years). Anal bleeding was the most common preoperative complaint (93.2%) followed by anal pain (60.2%), anal itching (43%), and constipation (41%). Hemorrhoids were classified as third degree in 132 patients (74%) and fourth degree in 45 patients (25.4%). Skin tags were detected in 86 patients (48.8%) and rectocele in 14 patients (7.9%). Data collected included patient demographics, type of anesthesia, and specific details of the surgery such as duration of the operation, distance from the staple line to the dentate line, need for complementary hemostasis, and any unexpected occurrences. Postoperative data collected included the degree of pain, which was evaluated on the basis of the type and dosage of analgesics required, laxative consumption, and the presence of bleeding, fever, urinary retention, or hematomas. Each patient completed a written questionnaire addressing these events. Patients returned for follow-up visits on days 7, 15, 30, and 90. Responses to pain, bleeding, fever, anal continence, recurrence of hemorrhoids, and level of satisfaction were compiled. The duration of the procedure ranged from 6 minutes to 2 hours (average 23 minutes), and most operations lasted no more than 20 minutes, with the exception of one that lasted 2 hours because of intraoperative bleeding. Intraoperative problems were minor. An additional one or a few sutures were required in 58.7% of patients to achieve perfect hemostasis. In 128 patients (72.3%) the hospital stay was less than 24 hours. Same-day surgery was chosen for 37 patients (20.9%). Pain was controlled with analgesia only using one to six doses of oral dipirona in 126 patients. Five patients were readmitted to the hospital: four for control of bleeding and one for conventional hemorrhoidectomy due to an acute episode of external hemorrhoidal thrombosis. At day 30, patients rated the efficacy of the procedure in alleviating preoperative symptoms as follows: 77.5% excellent; 16% good; 5.3% average, and 1.2% poor. At 3 months postoperatively no patient had had a recurrence of hemorrhoidal prolapse, and there were no instances of stenosis or anal incontinence. Surgeons also rated the efficacy of the procedure as excellent in 75%, good in 19.8%, average in 4.7%, and poor in 0.6%. With proper selection of patients and adequate stapling technique, stapled hemorrhoidectomy may be considered safe; it is easily learned, has a satisfactory degree of pain, and is well accepted by both patients and surgeons.
