Influence of Preoperative Educational Intervention for Patients Undergoing Fecal Ostomy Surgery: A Comparison Cohort Study.

PURPOSE: This aim of this study was to compare the impact on hospital stay and short-term overall complications prior to and following the introduction of an outpatient preoperative ostomy education program to an existing inpatient ostomy education program. DESIGN: A comparison cohort study. SUBJECTS AND SETTING: One hundred thirty-eight consecutive patients undergoing ostomy surgery were included. One group (n = 65, 47%) was given an experimental preoperative ostomy education intervention, along with standard care including a postoperative educational intervention during the initial hospital course. A second group (n = 73, 53%) received the same standardized education in the postoperative period. Data were collected from a single tertiary center located in Seville, Spain, during a 12-month period between July 2014 and June 2015. METHODS: Data were collected in 2 phases. Data from participants undergoing postoperative (standard) education were collected retrospectively. Data for the group receiving preoperative education were collective prospectively. Outcome variables were postoperative length of stay, surgical complications (severity was assessed by the Clavien-Dindo grading system), subsequent interventions, and readmission rates. RESULTS: Analysis indicated no differences between the average length of postoperative hospital stay (12.32 days in the preoperative education group vs 12.76 days in the postoperative education group, P = .401). In contrast, overall complications, mortality, and readmission rates were significantly higher in the preoperative education program group (P = .027, P = .047, and P = .046, respectively). CONCLUSIONS: Delivering a standardized educational intervention during the preoperative period versus postoperative education delivery during the ostomy surgery hospital course did not reduce length of stay. Analysis indicated that overall complications, mortality, and readmission rates were significantly higher in the preoperative education program group but we hypothesize that intervening factors may have influenced these outcomes.

Efficacy of Sacral Nerve Stimulation in Non-constipated Irritable Bowel Syndrome Patients: A Systematic Review.

BACKGROUND AND AIMS: Irritable bowel syndrome (IBS) is a prevalent disorder with a complex and heterogeneous physiopathology, including a dysregulation of gut-brain axis. Treatment for IBS is targeted to the predominant symptom and requires a multidisciplinary approach. This review aims to evaluate the efficacy and safety of sacral nerve stimulation in non-constipated IBS patients Methods: A literature search was carried out on MEDLINE, The Cochrane Central Register of Controlled Trials (CENTRAL) and Web of Science databases for all relevant articles. Quality of included papers was assessed using standardized guidelines Results: Of 129 initial citations, 7 articles met our predefined inclusion criteria, including five randomized trials, a pilot study and a descriptive follow-up study. Five of 7 studies reported a positive effect of sacral nerve stimulation on symptoms and quality of life improvement in non-constipated IBS patients. No study reported serious adverse events. CONCLUSIONS: Despite initial promising results of sacral nerve stimulation in non-constipated IBS patients, studies with larger sample sizes and longer follow-up are required.

Impact of a Donor Age >75 Years on the Survival of Liver Transplant Recipients.

BACKGROUND: An organ shortage is the reason why it is necessary to expand the pool of donors, which can be achieved by using elderly donors. The main goal of this study is to analyze the outcomes of liver transplant (LT) when it is performed with donors older than 75 years. METHODS: We carried out a retrospective case-control study (N = 212) that included LTs with donors older than 75 years (group A, n = 106 cases) that were performed in our center between the years 2010 and 2020. This cohort has been paired off with a similar control group (group B, n = 106) whose donors were significantly younger. A survival analysis using the Kaplan-Meier model was performed. RESULTS: Average (SD) age of donors in group A was statistically greater than group B (A, 79.1 [3.0] years vs B, 54.4 [15.3], P < .001). There were no differences either in the average age of the recipients or in the Model for End-Stage Liver Disease score of both groups. Indications for LT were distributed equally in both groups: the most common was cellular hepatocarcinoma followed by alcohol-related cirrhosis. Survival rates for group A were 81%, 78%, and 67%, in 1, 3, and 5 years, respectively, while in group B they were 85%, 76%, and 71%, respectively, without differences found between the groups (P = .57). CONCLUSIONS: Using elderly liver donors is safe, achieving good outcomes in terms of short- and midterm rates of survival.

Factores de riesgo para injertos hepáticos no válidos. Estudio multivariante a partir de las variables recogidas en el protocolo de donación de la Organización Nacional de Trasplantes / Risk Factors for No Valid Liver Graft. Multivariate Study Based on the Variables Included in the Donation Protocol of the National Trasplant Organisation

INTRODUCCIÓN: Entre las estrategias diseñadas para optimizar el número de injertos hepáticos existentes para trasplante, la implementación del proceso de valoración de injertos constituye una de las menos exploradas. El objetivo principal es identificar los factores de riesgo que presentan los donantes hepáticos para la «NO validez». Secundariamente analizamos la coincidencia entre la valoración del cirujano y la del anatomopatólogo en los donantes NO válidos. MATERIAL Y MÉTODO: Estudio retrospectivo realizado a partir de una base de datos prospectiva que analiza 190 donantes hepáticos, 95 válidos y 95 NO válidos. Se estudian las variables de cada uno de ellos correspondientes al protocolo de donación de la Organización Nacional de Trasplantes. Mediante el estudio multivariante determinamos los factores de riesgo independientes de NO validez. Cotejamos las causas de NO validez argumentadas con los hallazgos histopatológicos de dichos injertos. RESULTADOS: Los factores de riesgo independientes de NO validez en el estudio multivariante (p < 0,05) fueron: dislipemia, antecedentes personales médicos distintos a factores de riesgo cardiovascular y quirúrgicos abdominales, GGT, BrT, y el resultado de la ecografía hepática previa. Las dos causas más frecuentes de NO validez fueron: esteatosis y fibrosis. El 78% de las biopsias confirmaron la NO validez del injerto (en 57,9% del total coincidían los hallazgos histológicos con los descritos por el cirujano). El 22% restante de las biopsias no presentaban hallazgos patológicos. CONCLUSIONES: La determinación de los factores de riesgo de NO validez contribuirá al diseño de futuros scores de valoración que constituyan herramientas útiles en el proceso de valoración de injertos hepáticos

INTRODUCTION: Among the strategies designed to optimize the number of existing liver grafts for transplantation, the implementation of the graft assessment process is one of the least explored. The main objective is to identify the risk factors presented by liver donors for «NO validity». Secondly, we analyzed the coincidence between the surgeon's assessment and that of the anatomo-pathologist in the invalid donors. MATERIAL AND METHOD: Retrospective study conducted from a prospective database that analyzes 190 liver donors, 95 valid and 95 NOT valid. The variables of each of them corresponding to the donation protocol of the National Transplant Organization are studied. Through a multivariate study we determine the independent risk factors of NO validity. We checked the causes of NO validity argued with the histopathological findings of these grafts. RESULTS: The independent risk factors of non-validity in the multivariate study (P < .05) were: dyslipidemia, personal medical history other than cardiovascular and abdominal surgical risk factors, GGT, BrT, and the result of previous liver ultrasound. The 3 most frequent causes of NO validity were: steatosis, fibrosis and macroscopic appearance of the organ. 78% of the biopsies confirmed the NO validity of the graft (in 57.9% of the cases the histological findings coincided with those described by the surgeon). The 22.1% of the biopsies hadńt pathological findings. CONCLUSIONS: The determination of the risk factors of NO validity will contribute to the design of future assessment scores that are useful tools in the process of liver graft assessment)

Association of Negative Pressure Wound Therapy and Dermatotraction for Management of Necrotizing Soft Tissue Infections: A Case Series.

INTRODUCTION: Soft tissue infections (STIs), which include infections of the skin, subcutaneous tissue, fascia, and muscle, encompass a wide variety of heterogeneous pathologies. Treatment of STIs is based on surgical debridement of the affected area. One such treatment, negative pressure wound therapy (NPWT), has improved the management of STIs. OBJECTIVE: The purpose of this study is to assess the safety and utility of NPWT in conjunction with dermatotraction in the early stage management of necrotizing STIs. MATERIALS AND METHODS: The authors report a retrospective series of 3 cases in which NPWT and dermatotraction (NPWT-D) were used in an attempt to manage necrotizing STI. The NPWT-D device combination was employed to approximate the edges of the wounds. The NPWT device was changed every 2 or 3 days, and dermatotraction tension was adjusted concurrently. RESULTS: The NPWT-D device changes ranged from 3 to 4 times for 2 of the 3 patients, as 1 patient passed away secondary to STIs and therefore did not receive complete treatment. The total treatment ranged from 8 to 10 days in the remaining 2 patients. In both cases, complete wound closure was achieved while avoiding skin grafts. After 5 days of therapy in the incomplete treatment case, the wound area was reduced by about half. CONCLUSIONS: Based on the experiences herein, NPWT-D may be a safe and useful alternative surgical treatment for the management of necrotizing STIs. In the present cases, NPWT-D improved and shortened the wound healing process, and it achieved a tertiary wound closure, thereby avoiding the need for skin grafts.

Body Mass Index as a Prognostic Factor in Liver Transplantation.

OBJECTIVE: Obesity is one of the main growing epidemics of the last century and is responsible for many deaths worldwide. The aim of this study is to analyze the impact of the body mass index (BMI) of the recipient on survival and morbidity after liver transplantation (LT). MATERIAL AND METHODS: We conducted a retrospective cohort study of all transplanted recipients in a third-level hospital between 2006 and 2018. The following donor variables were analyzed: age, sex, weight, BMI, cause of death. Additionally, the following recipient variables were analyzed: age, sex, weight, height, BMI, procedure indication. Finally, outcome variables were analyzed: postoperative complications, early mortality, graft loss, and overall survival. This study strictly complies with the Helsinki Congress and the Istanbul Declaration regarding donor source. RESULTS: We analyzed 825 of 837 LTs from January 2006 to December 2018. These were grouped by BMI categories: 271 (29%) normal, 322 (34.3%) overweight, and 228 (24.3%) obesity. The overall survival at 5 years was 83% in the normal group, 76% in the overweight group, and 71% in the obesity group. These differences were statistically significant (P = .027). The early mortality rate was 4.42% in the normal weight group, 6.5% in the overweight group, and 5.26% in the obesity group. No differences were found between groups in terms of postoperative complications: hemorrhagic, vascular, biliary, respiratory, hemodynamic, digestive, renal, neurologic, rebel ascites, and infections. No differences were found regarding the need for re-operation. CONCLUSIONS: In this study, overall survival in LT decreases as the BMI of recipient increases; but overweight and obesity do not constitute a risk factor for early morbidity and mortality in LT.

Management of Large, Spontaneous Portosystemic Shunts in Liver Transplantation: Case Report and Review of Literature.

BACKGROUND: The presence of collateral circulation in liver cirrhosis patients with portal hypertension is quite frequent due to re-permeabilization of closed embryonic channels. In some cases, these shunts could measure over 1 cm wide, therefore, containing a significative blood flow. Its management during liver transplantation could be challenging due to possible complications resulting from either ligation of the shunts or from ignoring them. We present the case of a patient with recurrent hepatic encephalopathy (HE) and a large spontaneous portosystemic shunt (SPSS) who submitted to liver transplant and review the literature identifying options, complications, and outcomes with the aim of facilitating decision making. MATERIAL AND METHODS: A 68-year-old, Spanish man diagnosed with liver cirrhosis with portal hypertension and recurrent episodes of HE is proposed for LT. The patient's Child-Pugh score was A6-B7, and the Model for End-stage Liver Disease score was 12. Preoperatively, a computed tomography scan showed a large SPSS running to the inferior cava vein. During the surgery, a small-sized portal vein and a large shunt measuring almost 3 cm wide were identified. After reperfusion, portal vein flow was 1000 to 1100 mL/min. Owing to the previous HE and the risk of low portal flow, the shunt was closed increasing the portal flow to 1800 mL/min. The patient was discharged without any complications. CONCLUSIONS: The presence of large SPSSs are frequent during LT. Decision making intraoperatively can be challenging due to possible complications derived from ligation of the SPSS or from ignoring it. Either preoperative assessment of a further HE risk or portal vein flow measurement after reperfusion are essential to achieve a correct resolution.

Incontinencia fecal en el paciente anciano. Revisión de conjunto / Fecal incontinence in older patients. A narrative review

La incontinencia fecal representa una de las principales causas de institucionalización en las últimas décadas de la vida de una persona, asociando además gran repercusión psicosocial y económica. La literatura muestra escasa evidencia cuando se trata de analizar de forma específica a este grupo de población, debido a la falta de uniformidad en la consideración de «paciente anciano» y en la dificultad de su detección y diagnóstico. El objetivo de este artículo ha sido realizar una revisión narrativa de los principales aspectos relacionados con la incontinencia fecal en el anciano y facilitar el manejo de estos pacientes. La asistencia para la defecación, las modificaciones dietéticas y el control de la consistencia de las deposiciones o el tratamiento farmacológico son en muchos casos medidas suficientes. No obstante, otras terapias como el biofeedback, la neuromodulación o el tratamiento quirúrgico no deben descartarse y han de ser valoradas de forma selectiva en pacientes ancianos

Fecal incontinence is one of the leading causes for the institutionalization of people in the last decades of life, associated with a great psychosocial and economic burden. The literature is scarce in this population group, due to the absence of universally accepted criteria to define "elderly patients" and difficulties in detection and diagnostic. The aim of this article was to conduct a narrative review of the main aspects related to fecal incontinence in older patients, providing management support. Toileting assistance, dietary change, controlling stool consistency and medical treatment can be used to treat these patients. Nevertheless, other therapies, such as biofeedback, neuromodulation or surgical treatment, can be considered in selected patients
