Higher Adherence to ERAS Society® Recommendations is Associated with Shorter Hospital Stay Without an Increase in Postoperative Complications or Readmissions in Bariatric Surgery: the Association Between Use of Enhanced Recovery After Surgery Protocols and Postoperative Complications after Bariatric Surgery (POWER 3) Multicenter Observational Study.

PURPOSE: The effectiveness of enhanced recovery after surgery (ERAS) pathways in patients undergoing bariatric surgery remains unclear. Our objective was to determine the effect of the ERAS elements on patient outcomes following elective bariatric surgery. MATERIALS AND METHODS: Prospective cohort study in adult patients undergoing elective bariatric surgery. Each participating center selected a single 3-month data collection period between October 2019 and September 2020. We assessed the 24 individual components of the ERAS pathways in all patients. We used a multivariable and multilevel logistic regression model to adjust for baseline risk factors, ERAS elements, and center differences RESULTS: We included 1419 patients. One hundred and fourteen patients (8%) developed postoperative complications. There were no differences in the incidence of overall postoperative complications between the self-designated ERAS and non-ERAS groups (54 (8.7%) vs. 60 (7.6%); OR, 1.14; 95% CI, 0.73-1.79; P = .56), neither for moderate-to-severe complications, readmissions, re-interventions, mortality, or hospital stay (2 [IQR 2-3] vs. 3 [IQR 2-4] days, 0.85; 95% CI, 0.62-1.17; P = .33) Adherence to the ERAS elements in the highest adherence quartile (Q1) was greater than 72.2%, while in the lowest adherence quartile (Q4) it was less than 55%. Patients with the highest adherence rates had shorter hospital stay (2 [IQR 2-3] vs. 3 [IQR 2-4] days, 1.54; 95% CI, 1.09-2.17; P = .015), while there were no differences in the other outcomes CONCLUSIONS: Higher adherence to ERAS Society® recommendations was associated with a shorter hospital stay without an increase in postoperative complications or readmissions.

Lesión pancreática aislada tras traumatismo abdominal cerrado: a propósito de un caso / Isolated pancreatic injury after blunt abdominal trauma: a case report

Introducción. La incidencia de lesiones traumáticas del páncreas es baja debido a su localización retroperitoneal, y las lesiones aisladas son excepcionales debido a la proximidad del páncreas a otros órganos y estructuras vasculares. Caso clínico. Presentamos el caso de un varón de 21 años con lesión aislada del páncreas tras traumatismo abdominal cerrado, que precisó manejo quirúrgico. Discusión. Las lesiones pancreáticas aisladas secundarias a traumatismo son raras, pero debemos tenerlas en cuenta en un paciente politraumatizado. Su diagnóstico precoz y manejo adecuado son cruciales para evitar el desarrollo de complicaciones

Introduction. The incidence of traumatic injuries to the pancreas is low due to its retroperitoneal location, and isolated injuries are rare due to the proximity of the pancreas to other vascular organs and structures. Clinical case. We present the case of a 21-year-old man with an isolated lesion of the pancreas after blunt abdominal trauma, which required surgical management.Discussion. Isolated pancreatic injuries secondary to trauma are rare but must be taken into account in a multiple trauma patient. Its early diagnosis and proper management are crucial to avoid the development of complications

Isquemia crítica de miembros inferiores en paciente joven: presentación atípica del síndrome de atrapamiento poplíteo / Critical lower extremity ischemia in a young patient: atypical presentation of the popliteal artery entrapment syndrome

Introducción. El síndrome de atrapamiento poplíteo es una entidad infrecuente, cuya incidencia oscila entre 0,17 y 3,5 %, representando una de las principales causas de isquemia en miembros inferiores en adultos jóvenes. Suele manifestarse con claudicación intermitente (69 %) o isquemia aguda (26 %), siendo muy rara su presentación con isquemia crítica de miembros inferiores. Caso clínico. Paciente de 30 años quien presentó úlcera subungueal en primer dedo de pie derecho con dolor intenso. En la exploración física no se palpaban pulsos distales y se observó palidez cutánea intensa y frialdad. Se realizó arteriografía donde se observó defecto de repleción de bordes regulares y desplazamiento medial de la arteria poplítea. La resonancia magnética mostró una inserción anómala del gastrocnemio medial, con lo que se hizo diagnóstico de síndrome de atrapamiento poplíteo tipo I. Mediante abordaje posterior se realizó reconstrucción vascular con injerto venoso y sección tendinosa del gastrocnemio medial. En el postoperatorio inmediato el paciente recupera pulso pedio y en el seguimiento a un año el paciente no presenta clínica de isquemia de miembros inferiores, encontrándose el baipás permeable. Discusión. A pesar de su baja incidencia, es importante incluir el síndrome de atrapamiento poplíteo en el diagnóstico diferencial de isquemia en miembros inferiores en adultos jóvenes. Su presentación con isquemia crítica es excepcional, encontrando muy pocos casos publicados en la literatura. La reconstrucción arterial precoz mediante injerto o plastia con material autólogo constituye el tratamiento de elección

Introduction. The popliteal entrapment syndrome is an infrequent entity, whose incidence ranges between 0.17 and 3.5%, representing one of the main causes of lower limb ischemia in young adults. It usually manifests with intermittent claudication (69%) or acute ischemia (26%), being very rare its presentation with critical ischemia of the lower limbs.Clinical case. A 30-year-old patient with a history of smoking, with no other risk factors, who presented with a subungual ulcer on the first right toe. On physical examination, distal pulses are not palpated, intense skin paleness and coldness are observed. Magnetic resonance imaging showed an anomalous insertion of the medial gastrocnemius with extrinsic compression of the popliteal artery, confirming a diagnosis of popliteal entrapment syndrome type I. Vascular reconstruction with venous graft and tendon section of the medial gastrocnemius was performed through a posterior approach. In the immediate postoperative period, the patient recovers a pediatric pulse and in the one-year follow-up the patient does not present symptoms of lower limb ischemia, finding the bypass patent. Discussion. Despite its low incidence, it is important to include popliteal impingement syndrome in the differential diagnosis of lower limb ischemia in young adults. Its presentation with critical ischemia is exceptional, finding very few cases published in the literature. Early arterial reconstruction by graft or plasty with autologous material is the treatment of choice

¿Qué hacer ante una neoplasia mucinosa papilar intraductal de páncreas? Nuestra experiencia / What to do with an intraductal papilary mucinous pancreatic neoplasm? Our experience

INTRODUCCIÓN: Las neoplasias quísticas pancreáticas representan un grupo heterogéneo de enfermedades, donde la neoplasia mucinosa papilar intraductal está alcanzando protagonismo. El objetivo del estudio es revisar nuestra serie de neoplasias quísticas pancreáticas intervenidas y valorar la concordancia con las recomendaciones de Fukuoka. MÉTODOS: Revisamos de forma retrospectiva nuestra experiencia analizando los datos clínicos y radiológicos, la indicación quirúrgica y el estudio histológico de los 11 pacientes intervenidos en nuestro centro desde julio de 2011 a julio de 2015 por esta enfermedad, con el objetivo de valorar la concordancia con los consensos actuales. RESULTADOS: En nuestra serie la mayoría de los casos (7/11) presentaban síntomas al diagnóstico. El diagnóstico preoperatorio se alcanzó en 10 pacientes mediante radiología y/o ecoendoscopia. Las indicaciones quirúrgicas fueron presencia de síntomas, datos radiológicos de sospecha de malignidad y neoplasia de rama secundaria asintomática mayor a 30mm. Los hallazgos en estudio histológico fueron de malignidad en 6/11 (2 neoplasia invasiva, 4 displasia de alto grado), displasia moderada en 2/11, displasia de bajo grado en 2/11 y ausencia de displasia en un paciente. CONCLUSIONES: La indicación quirúrgica de las neoplasias mucinosas papilares intraductales de páncreas depende de los síntomas asociados, dimensiones, localización, riesgo y sospecha de malignidad

INTRODUCTION: Cystic pancreatic neoplasms are a heterogeneous group of pathology, and intraductal papillary mucinous neoplasia is becoming more common. The aim of this study is to review our series of cystic pancreatic neoplasms that underwent surgery and to evaluate the similarities with Fukuoka recommendations. METHODS: Retrospective review of our experience analyzing clinical and radiological data, indication for surgery and pathology study of 11 patients operated on in our centre from july 2011 to july 2015, aiming to evaluate the degree of agreement with the current consensus. RESULTS: In our series the majority of cases (7/11) had symptoms at diagnosis. Preoperative diagnosis was achieved in 10 patients using radiology and/or endoscopy. Indications for surgery were the presence of symptoms, radiological data suspicious of malignancy, and secondary branch neoplasia over 30mm. Pathological findings were malignancy in 6/11 cases (2 invasive neoplasia, 4 high grade dysplasia), moderate dysplasia in 2/11, low-grade dysplasia in 2/11 and no dysplasia in one patient. CONCLUSIONS: Surgical indication of intraductal mucinous pancreatic neoplasms depends on the associated symptoms, size, location, risk and suspicion of malignancy
