Association between use of enhanced recovery after surgery protocols and postoperative complications after gastric surgery for cancer (POWER 4): a nationwide, prospective multicentre study.

INTRODUCTION: The effectiveness of the Enhanced Recovery After Surgery (ERAS) protocols in gastric cancer surgery remains controversial. METHODS: Multicentre prospective cohort study of adult patients undergoing surgery for gastric cancer. Adherence with 22 individual components of ERAS pathways were assessed in all patients, regardless of whether they were treated in a self-designed ERAS centre. Each centre had a three-month recruitment period between October 2019 and September 2020. The primary outcome was moderate-to-severe postoperative complications within 30 days after surgery. Secondary outcomes were overall postoperative complications, adherence to the ERAS pathway, 30 day-mortality and hospital length of stay (LOS). RESULTS: A total of 743 patients in 72 Spanish hospitals were included, 211 of them (28.4 %) from self-declared ERAS centres. A total of 245 patients (33 %) experienced postoperative complications, graded as moderate-to-severe complications in 172 patients (23.1 %). There were no differences in the incidence of moderate-to-severe complications (22.3% vs. 23.5%; OR, 0.92 (95% CI, 0.59 to 1.41); P = 0.068), or overall postoperative complications between the self-declared ERAS and non-ERAS groups (33.6% vs. 32.7%; OR, 1.05 (95 % CI, 0.70 to 1.56); P = 0.825). The overall rate of adherence to the ERAS pathway was 52% [IQR 45 to 60]. There were no differences in postoperative outcomes between higher (Q1, > 60 %) and lower (Q4, ≤ 45 %) ERAS adherence quartiles. CONCLUSIONS: Neither the partial application of perioperative ERAS measures nor treatment in self-designated ERAS centres improved postoperative outcomes in patients undergoing gastric surgery for cancer.

Anastomosis gastroyeyunal con separación gástrica parcial frente al tratamiento endoscópico para el tratamiento del síndrome de obstrucción antroduodenal de causa maligna / Stomach-partitioning gastrojejunostomy versus stent placement for the treatment of malignant gastric outlet obstruction

Introducción: El síndrome de obstrucción antroduodenal es una complicación presente en neoplasias avanzadas. Se caracteriza por clínica de obstrucción gastrointestinal alta, con desnutrición progresiva, y se asocia con una disminución de la supervivencia. La derivación mediante gastroyeyunostomía y el tratamiento endoscópico (TE) son las alternativas para el tratamiento del síndrome de obstrucción antroduodenal. El objetivo de este estudio es comparar la eficacia y la supervivencia de ambas. Métodos: Estudio monocentro, observacional y prospectivo de 58 pacientes con síndrome de obstrucción antroduodenal que recibieron tratamiento quirúrgico mediante gastroyeyunostomía con separación gástrica parcial (GYSGP) o TE con prótesis enterales autoexpandibles entre los años 2007-2018. Resultados: A 30 pacientes se les realizó GYSGP y a 28 pacientes TE. La edad media de los pacientes con GYSGP fue significativamente menor (69 vs. 78 años, p = 0,001). No hubo diferencias en cuanto al sexo, el riesgo anestésico-quirúrgico ni la etiología de la neoplasia. Las complicaciones posprocedimiento fueron superiores, aunque no significativas, en el grupo de GYSGP (p = 0,156). El TE se asoció con una menor estancia hospitalaria (p = 0,02) y una mayor precocidad de la tolerancia oral (p < 0,0001). Sin embargo, los pacientes presentaron tasas más altas de obstrucción persistente y recurrente (p = 0,048 y 0,01, respectivamente), unos peores objetivos energéticos (p = 0,009) y una supervivencia menor (9,61 vs. 4,47 meses, p = 0,008). Conclusiones: La GYSGP obtiene una mayor permeabilidad luminal, una mejor tolerancia a la vía oral y una mayor supervivencia. El TE estaría recomendado para pacientes no subsidiarios de la cirugía con un pronóstico limitado a corto plazo

Introduction: Gastric outlet obstruction is a complication of advanced tumors. It causes upper gastrointestinal obstruction, with progressive malnutrition and reduced survival. Currently, gastrojejunostomy or stent placement (SP) are feasible alternatives for the treatment of malignant gastric outlet obstruction. The aim of this study is to compare the efficacy and survival of both techniques. Methods: Single-center observational and prospective study of 58 patients with gastric outlet obstruction who underwent surgical treatment with stomach-partitioning gastrojejunostomy (SPGJ) or SP with self-expanding intraluminal prostheses between 2007 and 2018. Results: Thirty patients underwent SPGJ and 28 SP. The mean age of the first group was significantly lower (69 vs. 78 years, respectively; P = .001). There were no statistically significant differences in terms of sex, perioperative risk or tumor etiology. Postoperative complications were non-significantly higher in the SPGJ group (P = .156). SP was associated with a shorter hospital stay (P = .02) and faster oral intake (P < .0001). However, SP had significantly higher rates of persistent and recurrent obstruction (P = .048 and .01, respectively), poorer energy targets (P=.009) and shorter survival (9.61 vs. 4.47 months; P = .008). Conclusions: SPGJ presents greater luminal permeability, better oral intake and greater survival than SP. SP is preferable for non-surgical patients with a limited short-term prognosis
