Abstract
Background

Retroperitoneal sarcoma (RPS) is a rare malignancy requiring complex surgical management. While Enhanced Recovery After Surgery (ERAS) protocols have improved outcomes in various surgical specialties, their implementation in RPS remains inconsistent.

Objective

This study aimed to evaluate current perioperative care practices for RPS surgery across Spain and Portugal, identifying gaps in protocol standardization and assessing the feasibility of consensus-based approaches.

Methods

A structured online survey was distributed to members of the Spanish and Portuguese Societies of Surgeons. The questionnaire encompassed five domains: demographics, preoperative, intraoperative, and postoperative practices, and attitudes toward perioperative consensus.

Results

Among 266 survey accesses, 37 complete responses were analyzed. Only 27% of respondents reported having a dedicated ERAS protocol for RPS, though 89.2% employed ERAS pathways for other surgeries. Prehabilitation elements—such as smoking cessation (21.6%), nutritional support (73%), and supervised physical therapy (37.8%)—were inconsistently applied. Intraoperatively, goal-directed fluid therapy was used by 51.4%, while 97.3% adhered to restrictive transfusion thresholds. Postoperative variability was notable in diet resumption, mobilization, and nasogastric tube use. All respondents supported the creation of an RPS-specific perioperative care consensus.

Conclusions

There is marked heterogeneity in perioperative care for RPS across Iberian centers. Standardized, evidence-based guidelines are urgently needed to improve consistency and optimize patient outcomes.

Resumen
Introducción

El sarcoma retroperitoneal (SRP) es una neoplasia infrecuente que requiere un manejo quirúrgico complejo. Aunque los protocolos de Enhanced Recovery After Surgery (ERAS) han demostrado mejorar los resultados en diversas especialidades quirúrgicas, su implementación en SRP es aún inconsistente.

Objetivo

Evaluar las prácticas actuales en el cuidado perioperatorio de la cirugía del SRP en España y Portugal, identificando deficiencias en la estandarización de protocolos y explorando la necesidad de enfoques basados en consenso.

Métodos

Se distribuyó una encuesta estructurada en línea a miembros de las Asociacón Española de Cirujanos y Sociedad Portuguesa de Cirugía. El cuestionario abarcó cinco dominios: datos demográficos, prácticas preoperatorias, intraoperatorias y postoperatorias, y actitudes hacia un consenso en relación al perioperatorio.

Resultados

De 266 accesos a la encuesta, se analizaron 37 respuestas completas. Solo el 27% de los encuestados afirmó tener un protocolo ERAS específico para SRP, aunque el 89,2% aplicaba ERAS en otras cirugías. Elementos de prehabilitación —como cese del hábito tabáquico (21,6%), soporte nutricional (73%) y fisioterapia supervisada (37,8%)— se aplicaban de forma inconsistente. Intraoperatoriamente, el 51,4% utilizó terapia de fluidos guiada por objetivos, y el 97,3% siguió umbrales transfusionales restrictivos. La variabilidad postoperatoria fue notable en la reanudación de la dieta, movilización precoz y uso de sonda nasogástrica. Todos los participantes apoyaron la creación de un consenso específico para el cuidado perioperatorio en SRP.

Conclusiones

Existe una marcada heterogeneidad en el manejo perioperatorio del SRP en los centros ibéricos. Se necesitan con urgencia guías estandarizadas, basadas en evidencia, para mejorar la coherencia de la atención y optimizar los resultados de los pacientes.
