Análisis de eventos adversos en los servicios de cirugía general y aparato digestivo. Estudio multicéntrico / Analysis of adverse events in general surgery: A multicenter study

Introducción: El conocimiento de los eventos adversos (EA) en los hospitales de agudos es un aspecto de especial relevancia en la seguridad del paciente. Su incidencia oscila entre un 3-17% y la cirugía se relaciona con la aparición de entre un 46-65% de todos los EA. Material y métodos: Se realiza un estudio observacional, descriptivo, retrospectivo y multicéntrico, con la participación de 31 hospitales de agudos españoles, para la determinación y análisis de los EA en los servicios de cirugía general. Resultados: La prevalencia de EA fue del 31,53%. Los tipos de EA más frecuentes fueron de tipo infeccioso (35%). Los pacientes con mayores grados de ASA, mayor complejidad y un tipo de ingreso urgente son factores asociados a la presencia de EA. A la mayoría de los pacientes se les atribuyó una categoría de daño F (daño temporal al paciente que requiera iniciar o prolongar la hospitalización) (58,42%). El 14,69% de los EA son considerados graves. El 34,22% de los EA se consideraron evitables. Conclusiones: La prevalencia de EA en los pacientes de cirugía general y del aparato digestivo (CGAD) es elevada. La mayor parte de los EA fueron de tipo infeccioso. El EA más frecuente fue la infección de herida o sitio quirúrgico. Los pacientes con mayores grados de ASA, mayor complejidad y un tipo de ingreso urgente son factores asociados a la presencia de EA. La mayoría de los EA detectados han supuesto un daño leve o moderado sobre los pacientes. Alrededor de un tercio de EA fueron evitables.(AU)

Introduction: Knowledge of adverse events (AE) in acute care hospitals is a particularly relevant aspect of patient safety. Its incidence ranges from 3% to 17%, and surgery is related to the occurrence of 46%-65% of all AE. Material and methods: An observational, descriptive, retrospective, multicenter study was conducted with the participation of 31 Spanish acute-care hospitals to determine and analyze AE in general surgery services. Results: The prevalence of AE was 31.53%. The most frequent types of AE were infectious (35%). Higher ASA grades, greater complexity and urgent-type admission are factors associated with the presence of AE. The majority of patients (58.42%) were attributed a category F event (temporary harm to the patient requiring initial or prolonged hospitalization); 14.69% of AE were considered severe, while 34.22% of AE were considered preventable. Conclusions: The prevalence of AE in General and GI Surgery (GGIS) patients is high. Most AE were infectious, and the most frequent AE was surgical site infection. Higher ASA grades, greater complexity and urgent-type admission are factors associated with the presence of AE. Most detected AE resulted in mild or moderate harm to the patients. About one-third of AE were preventable.(AU)

Advanced Lipoproteins and Lipidomic Profile in Plasma Determined by Nuclear Magnetic Resonance Before and After Bariatric Surgery.

BACKGROUND: Obesity is related to cardiovascular risk factors (CVRF) such as dyslipidemia, diabetes, and hypertension, which increase mortality. Basic lipid determinations could underestimate the true atherogenic risk of patients and the impact of bariatric surgery. The objective of the study is to demonstrate the change in the advanced molecular profile of lipoproteins determined by nuclear magnetic resonance spectroscopy in plasma after bariatric surgery, thus reducing the risk of cardiovascular disease. MATERIAL AND METHODS: Descriptive, observational, and prospective study in obese patients undergoing bariatric surgery. Advanced lipid profile was analyzed in plasma from the immediate preoperative period and at the 18th postoperative month by sending samples and performing plasma magnetic resonance spectroscopy in the BiosferTreslab® laboratory. RESULTS: Fifty-two patients were included. Average age of 46.3 years; 63.46% were women, 36.54% men. The average BMI was 43.57; the abdominal perimeter 133.50 cm; 32.6% were diabetics under medical treatment, 44.23% hypertensive, and 19.23% smokers; 86.53% of the patients presented alterations in at least one of the analytical parameters in the lipid study. Twenty-nine (55.7%) underwent banded gastric bypass (PGB), 19.23% underwent GBP, and 17.31% vertical gastrectomy. The rest were revision surgeries, two BPG-A and two biliopancreatic diversions after GV. All patients presented some improvement in advanced molecular profile of lipoproteins. Twenty percent of the patients normalized all the parameters. CONCLUSIONS: Bariatric surgery improves advanced molecular profile of lipoproteins, decreasing CVRF. Analysis of the characteristics of lipoprotein particles by NMR spectrometry is optimal for studying lipoprotein metabolism in patients undergoing bariatric surgery.

Ligamentum Teres Cardiopexy Might Not Prevent Gastro-esophageal Reflux After Laparoscopic Sleeve Gastrectomy: Case Series.

Roux-en-Y gastric bypass (RYGB) is considered the gold standard procedure in patients with obesity and gastroesophageal reflux (GERD), but in patients with preoperative hiatal hernia (HH) or GERD, who are unfit for RYGB, there are no clear guidelines. Ligamentum teres cardiopexy (LTC) has been proposed as an effective alternative. The purpose of this study was to analyze medium-term results of LTC procedure associated with laparoscopic sleeve gastrectomy (LSG) in patients with GERD or HH, according to the absence of pathologic acid reflux in esophageal 24 h pH monitoring test, symptom release, or PPI reduction. Five patients underwent LSG-LTC between March 2018 and October 2019. In one patient, the effectiveness of LTC as an anti-reflux procedure could not be assessed because of conversion to RYGB was required. After a follow-up period of 30 [24-42] months and excessive BMI loss of 62.74 ± 18.18%, GERD recurrence was observed in 75% of patients. The study was discontinued due to unsatisfactory preliminary results with LTC. Our results suggest that LTC might not prevent GERD after LSG in patients with preoperative GERD or HH.

Mechanical triangular esophagogastrostomy: Technical aspects and initial results.

INTRODUCTION: Esophageal cancer represents the eighth neoplasm worldwide. The therapeutic approach is interdisciplinary, with surgery being the most effective option. Several techniques have been proposed to perform esophagogastrostomy after esophagectomy, among them mechanical triangular esophagogastrostomy (MT), with a little experience published in the Western literature on the latter. The objective of this study is to describe the technical aspects and initial results of MT anastomosis. METHODS: A retrospective review of the patients who underwent esophagectomy according to the McKeown technique was performed, those in which MT anastomosis was implemented, between October 2017 and March 2020 in our hospital. RESULTS: 14 patients were included, with a mean age of 63 years. The mean operative time was 436 min (360-581), being diagnosed of anastomotic leak (AL) 3 of the 14 patients (21.4%), as well as 3 patients presented anastomotic stenosis (AS). The median stay was 20 days, without any death in the series. DISCUSSION: Multiple publications suggest the superiority in terms of AL and AS of the mechanical triangular anastomosis, which was also observed in our series, in which despite the small sample, a rapid improvement was observed in the indicators after the first cases. Therefore, this type of anastomosis may be a safe option for performing esophagogastric anastomosis after esophagectomy, being necessary more definitive conclusive studies.

Esofagogastrostomía triangular mecánica: aspectos técnicos y resultados iniciales / Mechanical triangular esophagogastrostomy: Technical aspects and initial results

IntroducciónEl cáncer de esófago representa la octava neoplasia a nivel mundial. El abordaje terapéutico es interdisciplinar y la cirugía es la opción más eficaz. Se han planteado varias técnicas para la realización de la esofagogastrostomía posterior a la esofagectomía, entre ellas, la esofagogastrostomía triangular mecánica, con muy poca experiencia publicada en la literatura occidental. El objetivo de este estudio es describir los aspectos técnicos y los resultados iniciales de la instauración de anastomosis triangular mecánica.MétodosSe realizó una revisión retrospectiva de los pacientes tratados mediante esofaguectomía según la técnica de McKeown, en los cuales se realizó anastomosis triangular mecánica entre octubre de 2017 y marzo de 2020 en nuestro hospital.ResultadosFueron incluidos 14 pacientes, con una media de edad de 63 años. El tiempo operatorio promedio fue de 436 min (360-581); fueron diagnosticados de fuga anastomótica 3 de los 14 pacientes (21,4%) y otros 3 pacientes presentaron estenosis anastomótica. La mediana de estancia fue de 20 días, sin ningún fallecimiento en la serie.ConclusionesMúltiples publicaciones señalan la superioridad en términos de fuga anastomótica y estenosis anastomótica de la anastomosis triangular mecánica. Esto también se observa en nuestra serie, en la cual, a pesar de lo reducido de la muestra, se observó una rápida mejoría en los indicadores posterior a los primeros casos, por lo que este tipo de anastomosis puede ser una opción segura para la confección de la anastomosis esofagogástrica posterior a la esofaguectomía. Son necesarios más estudios para alcanzar conclusiones definitivas (AU)

Predictive Power of the "Trigger Tool" for the detection of adverse events in general surgery: a multicenter observational validation study.

BACKGROUND: In spite of the global implementation of standardized surgical safety checklists and evidence-based practices, general surgery remains associated with a high residual risk of preventable perioperative complications and adverse events. This study was designed to validate the hypothesis that a new "Trigger Tool" represents a sensitive predictor of adverse events in general surgery. METHODS: An observational multicenter validation study was performed among 31 hospitals in Spain. The previously described "Trigger Tool" based on 40 specific triggers was applied to validate the predictive power of predicting adverse events in the perioperative care of surgical patients. A prediction model was used by means of a binary logistic regression analysis. RESULTS: The prevalence of adverse events among a total of 1,132 surgical cases included in this study was 31.53%. The "Trigger Tool" had a sensitivity and specificity of 86.27% and 79.55% respectively for predicting these adverse events. A total of 12 selected triggers of overall 40 triggers were identified for optimizing the predictive power of the "Trigger Tool". CONCLUSIONS: The "Trigger Tool" has a high predictive capacity for predicting adverse events in surgical procedures. We recommend a revision of the original 40 triggers to 12 selected triggers to optimize the predictive power of this tool, which will have to be validated in future studies.

Multicentre cohort study of acute cholecystitis management during the COVID-19 pandemic.

PURPOSE: To analyse acute cholecystitis (AC) management during the first pandemic outbreak after the recommendations given by the surgical societies estimating: morbidity, length of hospital stay, mortality and hospital-acquired SARS-CoV-2 infection rate. METHODS: Multicentre-combined (retrospective-prospective) cohort study with AC patients in the Community of Madrid between 1st March and 30th May 2020. 257 AC patients were involved in 16 public hospital. Multivariant binomial logistic regression (MBLR) was applied to mortality. RESULTS: Of COVID-19 patients, 30 were diagnosed at admission and 12 patients were diagnosed during de admission or 30 days after discharge. In non-COVID-19 patients, antibiotic therapy was received in 61.3% of grade I AC and 40.6% of grade II AC. 52.4% of grade III AC were treated with percutaneous drainage (PD). Median hospital stay was 5 [3-8] days, which was higher in the non-surgical treatment group with 7.51 days (p < 0.001) and a 3.25% of mortality rate (p < 0.21). 93.3% of patients with SARS-CoV-2 infection at admission were treated with non-surgical treatment (p = 0.03), median hospital stay was 11.0 [7.5-27.5] days (p < 0.001) with a 7.5% of mortality rate (p > 0.05). In patients with hospital-acquired SARS-CoV-2 infection, 91.7% of grade I-II AC were treated with non-surgical treatment (p = 0.037), with a median hospital stay of 16 [4-21] days and a 18.2% mortality rate (p > 0.05). Hospital-acquired infection risk when hospital stay is > 7 days is OR 4.7, CI 95% (1.3-16.6), p = 0.009. COVID-19 mortality rate was 11.9%, AC severity adjusted OR 5.64 (CI 95% 1.417-22.64). In MBLR analysis, age (OR 1.15, CI 95% 1.02-1.31), SARS-CoV-2 infection (OR 14.49, CI 95% 1.33-157.81), conservative treatment failure (OR 8.2, CI 95% 1.34-50.49) and AC severity were associated with an increased odd of mortality. CONCLUSION: In our population, during COVID-19 pandemic, there was an increase of non-surgical treatment which was accompanied by an increase of conservative treatment failure, morbidity and hospital stay length which may have led to an increased risk hospital-acquired SARS-CoV-2 infection. Age, SARS-CoV-2 infection, AC severity and conservative treatment failure were mortality risk factors.

Perforación intestinal por citomegalovirus durante un Síndrome de Reconstitución Inmune / Intestinal Perforation for Cytomegalovirus in Immune Reconstitution Syndrome

RESUMEN El síndrome de reconstitución inmune se produce debido a un aumento de la inmunocompetencia en pacientes previamente inmunocomprometidos. La situación es frecuente tras iniciar un tratamiento antirretroviral de alta eficacia, en pacientes con infección por el virus de inmunodeficiencia humana. En determinados casos, puede conllevar un empeoramiento paradójico de una infección previa. El citomegalovirus, es un germen oportunista que, en el seno de un síndrome de reconstitución inmune, puede dar lugar a perforación intestinal multifocal y peritonitis secundaria de difícil tratamiento. Es más frecuente en pacientes con recuento de linfocitos cooperadores inferior a 50 células/mm3 al iniciar el tratamiento antirretroviral. El objetivo es comunicar dicha situación a través, de un caso clínico para facilitar su sospecha lo más pronto posible, y realizar un tratamiento adecuado. Presentamos el caso de un paciente con virus de inmunideficiencia humana de reciente diagnóstico, en tratamiento con terapia antirretroviral de alta eficacia, que acude a urgencias con abdomen agudo secundario a perforación por citomegalovirus. La infección conlleva importante morbimortalidad, siendo imprescindible un diagnóstico temprano e iniciar precozmente el tratamiento antiviral intravenoso, asociado generalmente a tratamiento quirúrgico(AU)

ABSTRACT Immune reconstitution syndrome occurs due to increased immunocompetence in previously immunocompetent patients. The condition is frequent in patients with human immunodeficiency virus infection who have started a highly active antiretroviral therapy. In certain cases, the syndrome can lead to a paradoxical worsening of a previous infection. Cytomegalovirus is an opportunistic germ that, during an immune reconstitution syndrome, can lead to multifocal intestinal perforation and secondary peritonitis, in cases that are difficult to treat. The syndrome is more frequent in patients with CD4 lymphocyte count below 50/mm3 at the time of starting antiretroviral treatment. The objective is to communicate this situation through a clinical case presentation in order to facilitate suspicion as soon as possible, and to carry out appropriate treatment. We present the case of a patient with a recently diagnosed human immunodeficiency virus, under treatment with highly active antiretroviral therapy, who attended the emergency department with an acute abdomen secondary to perforation due to cytomegalovirus. Infection carries significant morbidity and mortality, and early diagnosis is essential and intravenous antiviral treatment should be started early, generally associated with surgical treatment(AU)

Esofagitis enfisematosa con perforación gástrica / Emphysematous esophagitis with gastric perforation

La esofagitis enfisematosa es una entidad extremadamente infrecuente sin prácticamente ningún caso descrito en la literatura. Presentamos el caso de una paciente con esofagitis y gastritis enfisematosa con afectación de toda la pared del esófago y el estómago al diagnóstico. Fue intervenida quirúrgicamente por perforación gástrica en dos ocasiones, realizándose cierre primario en ambas con evolución posterior favorable. Pese a la gran extensión de la esófago-gastritis enfisematosa al diagnóstico y la presencia de una perforación gástrica, es seguro realizar un manejo semejante a la gastritis enfisematosa siendo lo más conservadores posibles en caso de precisar cirugía

Emphysematous esophagitis is an extremely rare disease and there are very few previous reports in the literature. We report a case of emphysematous esophagitis and gastritis with complete affectation of the gastric and esophageal wall at diagnosis. Two surgical interventions were performed due to gastric perforation that was treated in both cases with primary closure. The post-operative recovery was satisfactory. Despite the large emphysematous esophago-gastritis affectation at diagnosis and the presence of gastric perforation, it is safe to perform the same management principles as with emphysematous gastritis. This should be as conservative as possible in case a surgical procedure is required

Nutrición enteral por yeyunostomía como causa de perforación y necrosis intestinal / Enteral feeding via jejunostomy as a cause of intestinal perforation and necrosis

Introducción: la yeyunostomía de alimentación es una excelente manera de nutrir por vía enteral a pacientes que no pueden tolerar dieta oral con una tasa de complicaciones baja. Se utiliza comúnmente una sonda de Foley, tubo de Ryle, de Kerh o catéter con aguja (Jejuno-Cath®). Caso clínico: presentamos el caso de un paciente varón de 80 años que presentó una perforación intestinal como consecuencia de la nutrición a través de un yeyunocath en el postoperatorio de una gastrectomía subtotal con reconstrucción en Y de Roux, y de otro paciente varón de 53 años con perforación gástrica y múltiples complicaciones postoperatorias, entre ellas, necrosis de un segmento de intestino delgado por impactación de nutrición enteral. Discusión: revisamos la literatura existente sobre esta rara complicación (AU)

Jejunostomy for enteral feeding is excellent for patients who cannot manage oral intake, with a low complication rate. A Foley catheter, Ryle tube, Kerh tube or needle-catheter (Jejuno-Cath®) are commonly used. It is a safe procedure but it can lead to severe complications. We present two cases: firstly, an 80 year old male who was admitted to the Emergency Room with a bowel perforation secondary to Jejuno-Cath® for enteral feeding after a subtotal gastrectomy with Roux-en-Y reconstruction; and secondly, a 53 year old male who was admitted to the Emergency Room due to gastric perforation developing multiple complications, including bowel necrosis and enteral feeding impaction. We have reviewed the recent literature with regard to this rare complication (AU)
