Home-based prehabilitation improves physical conditions measured by ergospirometry and 6MWT in colorectal cancer patients: a randomized controlled pilot study.

PURPOSE/BACKGROUND: Prehabilitation aims to improve physical condition in the preoperative period and, therefore, decrease the loss of cardiopulmonary capacity postoperatively, with the aim of reducing complications and promoting an early recovery. This study aims to evaluate the impact of home-based prehabilitation on the physical condition of patients treated surgically for colorectal cancer. METHODS: A prospective and randomized clinical study was conducted on 60 patients during two periods from October 2018 to February 2019 and from September 2019 to September 2020, in a single university hospital. Patients were randomized into two study groups (30 per group): prehabilitation vs. standard care. Changes in physical condition, measured at diagnosis, the day before surgery, and at 6-8 weeks after surgery using the cardiopulmonary exercise testing (CPET) and the 6-minute walk test (6MWT) were evaluated. RESULTS: Prehabilitation reduced postoperative complications (17.4% vs. 33.3%, p = 0.22) and hospital stay (5.74 vs. 6.67 days, p = 0.30). 6MWT showed a significant improvement in the prehabilitation group (+78.9 m). Six weeks after surgery, prehabilitation showed a significant improvement in the 6MWT (+68.9 m vs. -27.2 m, p = 0.01). Significant differences were also observed in the ergospirometry between the diagnosis and postoperative study (+0.79 METs vs. -0.84 METs, p = 0.001). A strong correlation was observed between CPET and 6MWT (0.767 (p < 0.001)). CONCLUSION: Home prehabilitation achieved lower overall postoperative complications than standard care and reached significant improvements in 6MWT and CET. A strong correlation was observed between CET and 6MWT, which allows validation of 6MWT as a valid and reliable measure of functional exercise capacity in colorectal patients when other, more specific and expensive tests are not available.

Surgery Is in Itself a Risk Factor for the Patient.

(1) Background: Adverse events (AE) affect about 1 in 10 hospitalised patients, and almost half are related to surgical care. The aim of this study is to determine the prevalence of AE in operated and non-operated patients in surgical departments in order to determine whether surgical treatment is a risk factor for AE. (2) Methods: A cross-sectional design that included 3123 patients of 34 public hospitals in the Community of Madrid determining the prevalence of AEs in operated and non-operated patients in surgical departments. (3) Results: The prevalence of AE in non-operated patients was 8.7% and in those operated was 15.8%. The frequency of AE was higher in emergency surgery (20.6% vs. 12.4%). The 48.3% of AEs led to an increase in hospital stay, and surgery was involved in 92.4% of cases. The most frequent AEs were related to hospital-acquired infection (42.63%), followed by those related to a procedure (37.72%). In the multivariate analysis, being operated on represented 2.3 times the risk of developing an AE. (4) Conclusions: Surgical sites are particularly vulnerable to AE. Surgical intervention alone is a risk factor for AE, and we must continue to work to improve the safety of both patient care and the working environment of surgical professionals.

Assessment of Body Composition as an Indicator of Early Peripheral Parenteral Nutrition Therapy in Patients Undergoing Colorectal Cancer Surgery in an Enhanced Recovery Program.

BACKGROUND: A poor body composition (BC) has been identified as a risk factor for patients with colorectal cancer (CRC). This study was performed to assess the effect of early peripheral parenteral nutrition (PPN) on BC in patients undergoing CCR surgery within an enhanced recovery program. METHODS: Patients with normal nutritional status were prospectively included between October 2016 and September 2019, randomized into two groups (PPN with periOlimel N4-E versus conventional fluid therapy) and subsequently classified according to their preoperative CT scan into high- or low-risk BC groups. Postoperative complications and length of hospital stay (LOS) were assessed. RESULTS: Of the 156 patients analyzed, 88 patients (56.4%) were classified as having high-risk BC according to CT measurements. PPN led to a 15.4% reduction in postoperative complications in high-risk vs. 1.7% in low-risk BC patients. In the multivariate analysis, high-risk BC was related to an OR (95% CI) of 2 (p = 0.044) of presenting complications and of 1.9 (p = 0.066) for major complications, and was associated with an increase in LOS of 3.6 days (p = 0.039). CONCLUSIONS: The measurement of patients' BC can allow for the identification of target patients where PPN has been proven to be an effective tool to improve postoperative outcomes.

Effect of Early Peripheral Parenteral Nutrition Support in an Enhanced Recovery Program for Colorectal Cancer Surgery: A Randomized Open Trial.

BACKGROUND: Peripheral parenteral nutrition allows repletion of acute nutrient deficiencies and could prevent further nutrition deficits before and after colorectal surgery. A randomized open study was performed to evaluate the effect of perioperative peripheral parenteral nutrition (PPN) support on postoperative morbidity after colorectal cancer surgery within an enhanced recovery program. METHODS: Patients were randomized into two groups: peripheral parenteral nutrition (PPN) (with Peri-Olimel N4-E) versus conventional fluid therapy (FT). Ninety-day postoperative complications, laboratory parameters, length of hospital stay, and compliance with the ERAS protocol were assessed. RESULTS: A total of 158 patients were analysed. The overall 90-day complication rate was 38.6% (61 patients), and 24 patients had major complications (Clavien-Dindo III-V) (15.2%). In the multivariate analysis, the intervention (PPN vs. FC) showed a protective effect against postoperative complications (p = 0.0031, OR = 0.2 (CI: 0.08-0.87)). Following ordinal regression, PPN and early oral tolerance showed a protective effect, being less likely to develop complications or to move from minor to major complications. In patients with low compliance to ERAS during the first postoperative day, PPN showed a protective effect, preventing 28% of morbidity. CONCLUSIONS: Perioperative peripheral parenteral nutrition (PPN) support with Peri-Olimel N4-E in colorectal cancer surgery associated with early oral intake could reduce postoperative complications.

Effect of Preoperative Immunonutrition on Postoperative Major Morbidity after Cytoreductive Surgery and HIPEC in Patients with Peritoneal Metastasis.

The effect of preoperative immunonutrition intake on postoperative major complications in patients following cytoreductive surgery (CRS) with or without hyperthermic intraperitoneal chemotherapy (HIPEC) was assessed. The accuracy of C-Reactive Protein (CRP) for detecting postoperative complications was also analyzed. Patients treated within a peritoneal carcinomatosis program in which a complete or optimal cytoreduction was achieved were retrospectively analyzed. They were divided into two groups based on whether preoperative immunonutrition (IMN) or not (non-IMN) were administered. Clinical and surgical variables and postoperative complications were gathered. Predictive values of major morbidity of CRP during the first 3 postoperative days (POD) were also evaluated. A total of 107 patients were included, 48 belonging to the IMN group and 59 to the non-IMN group. In multivariate analysis immunonutrition (OR 0.247; 95%CI 0.071-0.859; p = 0.028), and the number of visceral resections (OR 1.947; 95%CI 1.086-3.488; p = 0.025) emerged as independent factors associated with postoperative major morbidity. CRP values above 103 mg/L yielded a negative predictive value of 84%. Preoperative intake of immunonutrition was associated with a decrease of postoperative major morbidity and might be recommended to patients with peritoneal carcinomatosis following CRS. Measuring CRP levels during the 3 first postoperative days is useful to rule out major morbidity.

Effect of home-based prehabilitation in an enhanced recovery after surgery program for patients undergoing colorectal cancer surgery during the COVID-19 pandemic.

BACKGROUND: Surgery remains the first curative treatment for colorectal cancer. Prehabilitation seems to attenuate the loss of lean mass in the early postoperative period. However, its long-term role has not been studied. Lockdown due to the COVID-19 pandemic has forced to carry out the prehabilitation program at home. This study aimed to assess the effect of home prehabilitation on body composition, complications, and hospital stay in patients undergoing oncological colorectal surgery. METHODS: A prospective and randomized clinical study was conducted in 20 patients operated of colorectal cancer during COVID-19 lockdown (13 March to 21 June 2020) in a single university clinical hospital. Patients were randomized into two study groups (10 per group): prehabilitation vs standard care. Changes in lean mass and fat mass at 45 and 90 days after surgery were measured using multifrequency bioelectrical impedance analysis. RESULTS: Prehabilitation managed to reduce hospital stay (4.8 vs 7.2 days, p = 0.052) and postoperative complications (20% vs 50%, p = 0.16). Forty-five days after surgery, the loss of lean mass decreased (1.7% vs 7.1%, p = 0.17). These differences in lean mass were attenuated at 90 days; however, the standard care group increased considerably their fat mass compared to the prehabilitation group (+ 8.72% vs - 8.16%). CONCLUSIONS: Home prehabilitation has proven its effectiveness, achieving an attenuation of lean mass loss in the early postoperative period and a lower gain in fat mass in the late postoperative period. In addition, it has managed to reduce hospital stays and postoperative complications. REGISTRATION NUMBER: This article is part of an ongoing, randomized, and controlled clinical trial approved by the ethics committee of our hospital and registered in ClinicalTrials.gov in August 2018 with registration number NCT03618329.

The Thiel cadaveric model for pelvic floor surgery: Best rated in transferable simulation-based training for postgraduate studies.

OBJECTIVE: To determine whether the Thiel cadaveric model is better and more realistic than other surgical simulation techniques for learning pelvic floor and perineal surgical procedures according to the opinions of urogynecologists and surgeons participating in international postgraduate pelvic floor surgery courses using cadavers embalmed by the Thiel method. STUDY DESIGN: An observational prospective study was performed in urogynecologists and surgeons attending international postgraduate pelvic floor and perineal surgery courses using cadavers embalmed by the Thiel method. A survey was completed by the participants after finishing the course. Based on the answers collected, we analyzed the differences, including in the satisfaction degree and teaching level for each surgical procedure, between different surgical simulation models that the participants had already used and the Thiel simulation method employed. RESULTS: The students recognized that Thiel cadavers present more similarities to patients than other simulation methods. The Thiel cadaveric method was considered by most responders to be the best for the simulation of surgical procedures on the pelvic floor and perineum. Most of the surgeons surveyed recommended conducting these courses with Thiel cadavers for different colleagues in other specialties as a reliable simulation method for training for difficult surgical procedures. CONCLUSIONS: Participants in the course on pelvic floor surgery in Thiel cadavers recognized that this is the most realistic model for surgical simulation and the best way to gain confidence, self-determination and precise surgical skills for performing pelvic floor and perineal surgery.

Risk Analysis for Patient Safety in Surgical Departments: Cross-Sectional Design Usefulness.

(1) Background: Identifying and measuring adverse events (AE) is a priority for patient safety, which allows us to define and prioritise areas for improvement and evaluate and develop solutions to improve health care quality. The aim of this work was to determine the prevalence of AEs in surgical and medical-surgical departments and to know the health impact of these AEs. (2) Methods: A cross-sectional study determining the prevalence of AEs in surgical and medical-surgical departments was conducted and a comparison was made among both clinical areas. A total of 5228 patients were admitted in 58 hospitals in Argentina, Colombia, Costa Rica, Mexico, and Peru, within the Latin American Study of Adverse Events (IBEAS), led by the Spanish Ministry of Health, the Pan American Health Organization, and the WHO Patient Safety programme. (3) Results: The global prevalence of AEs was 10.7%. However, the prevalence of AEs in surgical departments was 11.9%, while in medical-surgical departments it was 8.9%. The causes of these AEs were associated with surgical procedures (38.6%) and nosocomial infections (35.4%). About 60.6% of the AEs extended hospital stays by 30.7 days on average and 25.8% led to readmission with an average hospitalisation of 15 days. About 22.4% resulted in death, disability, or surgical reintervention. (4) Conclusions: Surgical departments were associated with a higher risk of experiencing AEs.

Revisión narrativa de la prehabilitación en cirugía: situación actual y perspectivas futuras / A Narrative Review About Prehabilitation in Surgery: Current Situation and Future Perspectives

La prehabilitación tiene una concepción multimodal con tres pilares fundamentales: mejora en la condición física del paciente, optimización nutricional e intervención cognitiva para reducir el estrés y la ansiedad, además de otras medidas como la deshabituación tabáquica o la corrección de la anemia. El objetivo principal es la optimización del paciente durante el periodo de tiempo preoperatorio (diagnóstico-intervención) con la finalidad de mejorar la capacidad funcional y disminuir las complicaciones derivadas de la cirugía. Al igual que ocurre con los protocolos de rehabilitación multimodal, las acciones de los programas de prehabilitación tienen efectos sinérgicos, es decir, pequeños cambios que por sí solos no tienen transcendencia clínica pero que al sumarse producen una mejoría significativa en la evolución postoperatoria de los pacientes. Aunque se requieren más estudios que evalúen el impacto concreto de estos programas en poblaciones de pacientes con diversas patologías, intervenciones y distintos factores de riesgo, se hace necesaria su implementación progresiva en la práctica clínica habitual de nuestros pacientes. El objetivo de esta revisión narrativa es evaluar la literatura disponible sobre la prehabilitación en cirugía, haciendo especial hincapié en las estrategias actualmente establecidas, así como en las lagunas de conocimiento actuales y futuros focos de investigación

Prehabilitation has a multimodal conception based on three fundamental pillars: improvement of the patient's physical condition, nutritional optimization and cognitive intervention to reduce stress and anxiety, as well as other measures such as smoking cessation and correction of anemia. The aim of prehabilitation programs is to optimize the patient from the moment of diagnosis until the surgical intervention in order to reduce postoperative complications. As in the case of multimodal rehabilitation protocols, the actions of prehabilitation programs have synergistic effects, that is, small changes that, by themselves, do not have clinical significance but when added up, they produce a significant improvement in the postoperative evolution of patients. Although more studies are required to evaluate the impact of these programs on patients groups with different pathologies, interventions and risk factors, their progressive implementation is necessary in the daily clinical practice of our patients. The objective of this narrative review is to evaluate the available evidence about prehabilitation in surgery, focusing on current established strategies, knowledge gaps and future research
